    Apparatus for Unloading Particulate Material from Silos into Mobile Receptacles Technical Field The present invention relates to the extraction of goods from silos or fixed vertical receptacles into smaller mobile receptacles.
    In particular, the present invention relates to an apparatus for increasing the safety of unloading from a silo to a mobile container while reducing the amount of goods spilled during that process.
    Technological Background of the Invention The invention relates to particulate material which is stored and maintained in oversized silos (+300m*) for delivery to a Final Customer, in particular the pouring of granular materials from such silos. The pouring or extraction of those materials from silos and other types of vertical containers is a common practice for many industrial logistics providers.
    These logistics providers have certain higher level organizations and campaigns that try to improve the safety, efficiency and quality of their work, but also in terms of environmental and social impact on the transport of goods. The ECTA (European Chemical Transport Association) is an example of such an organization, which seeks to unite logistics service providers and improve their way of working. Another example is Operation clean sweep, a campaign that encourages logistics service providers handling plastic resins to adopt techniques and practices to aim for zero loss of granules, flakes and powders. After all, those losses would end up in waterways, which eventually lead to the ocean and damage the animals and plants that live there.
    Industrial logistics providers perform such extractions of materials that are stored and preserved in silos on a very regular basis using gravity dumping or pumping. This often requires the mobile receptacle to be placed directly under the silo, as most such silos have an extraction outlet located at the bottom. That discharge process runs at a specific flow rate, depending on the type of material and the dimensions of the respective extraction outlet, which describes the amount of material that leaves the silo during a specific period of time. To ensure that the correct amount of material leaves the silo and enters the mobile container, the process is often timed manually or, in the case of more expensive systems, electronically timed by the pump or the dump system itself. Timing should be done with care, as a sufficient amount of material should be loaded to meet customer needs, while avoiding overloading the mobile receptacle and causing material spillage. In some cases, a quantity of goods is already present in the mobile receptacle, which must then be taken into account.
    Industrial logistics service providers generally need to store a variety of materials, each of which is stored in one or more silos. Different silos are used to store those diverse materials, and the number of extraction mechanisms available In the industrial service provider's installation, less than one extraction mechanism may be allocated to a single silo. That is, extraction mechanisms should be connected to one silo and then to another silo, and cleaned frequently between different extractions, especially when the next silo to be connected contains a different type of material, to prevent a residue from leading to contamination of new mobile receptacles to be loaded with a different type of material.
    The extraction outlet located at the bottom end of the silo can be used to discharge the granular material directly, or to connect an additional extraction tube and extend the extraction outlet.
    Some industrial logistics providers use a multi-storey solution, with at least 2 floors, where the ground level (the ground floor) is accessible to porters of mobile containers, such as trucks, trains or even boats.
    The first level (first floor) is used to support the silos and facilitate the process for the operator who is located on the first floor and performs the dumping of the stored materials into the receptacle, as it provides easier access to the extraction outlet of the silo, and is already located above the loading opening available on the mobile container itself.
    Such multi-storey solutions require an extraction tube to establish a connection between the extraction outlet of the silo and the loading opening in the mobile container.
    Those extraction tubes should be easily connectable to the silo, should be easy to clean and should make it possible to monitor the current level of granular material already loaded in the mobile container.
    Currently there are several automated telescopic bellows available on the market, which are equipped with an automatic level detection system.
    These make it possible to automatically interrupt the charging process when the desired level is reached in the mobile container to be filled.
    However, they take up a lot of space, which means they are less desirable in multi-storey loading solutions, require a lot of workspace when disconnected from a silo, require a labor intensive cleaning process and are quite expensive.
    Furthermore, when the particulate material is of synthetic origin, such as plastic or polymer granules, logistics providers face the challenge and are willing to work according to the rules set by organisations/campaigns to protect the environment and to remove plastic granules from the seawater without making the operation of a loading system a labour-intensive and complex process. There is thus a need for an 'easy to operate', affordable and safe landfill system that can be used to deposit the material from such silos into mobile receptacles.
    BRIEF SUMMARY OF THE INVENTION According to the present invention, there is provided an apparatus arranged for loading a mobile receptacle with particulate material from a silo, said silo comprising a vessel designed to contain said particulate material, having an outlet opening on the side. the underside of said silo for extracting said particulate material, which is adapted to connect an extraction tube and through which said particulate material is able to leave the silo under the influence of gravity to enter the mobile container, wherein said mobile receptacle is provided with a loading opening located in an upper portion of said mobile receptacle, the apparatus of the invention further comprising a flexible chute having an outer wall surrounding a hollow body adapted to be connected to a distal portion of the said extraction tube with a mutual locking means, said flexible chute comprising a proximal portion and a distal portion, said proximal portion of said flexible chute adapted to surround said distal portion of said extraction tube, said distal portion extending from said proximal portion and terminates at a free end of said flexible chute, said chute comprising a skirt connected to the distal portion of the chute and arranged to cover the loading opening on said mobile receptacle. As can be seen, the device according to the present invention enables an 'easy to operate' and safe system. As will become apparent from the following explanation, the flexible chute makes it possible to increase the safety of the pouring process from the silo to the mobile container, but at the same time it is easy to connect and disconnect from the existing pipe. on the silo, or even directly on the silo. Furthermore, the distal portion, which includes the rim connected to the distal portion, makes it possible to cover said loading opening on the mobile container, thereby preventing said particulate material from being spilled and released into the environment.
    During the loading process, the mobile container is positioned right under the extraction outlet of the silo. Afterwards, the person performing the loading process opens the loading hole of the mobile receptacle, which can be done directly from the loading floor through the through hole, by means of a hook or by means of a ladder in case no loading floor is available. Next, the operator moves the extraction tube to a position where said extraction tube is directly between the extraction outlet of the silo and the loading hole. The upper end of the extraction tube is then connected to the outlet opening of the silo to allow the particulate material in the silo to flow through the extraction tube and the loading hole into the mobile receptacle. The lower part of the extraction tube is connected to the device according to the invention. After the extraction tube has been lowered, the device according to the invention is located above the loading hole of the mobile receptacle, or (for a small part) in the loading hole.
    Particulate matter ricocheted upwards by impacting the lower part of the mobile receptacle will bounce off the rim and remain in the mobile receptacle instead of exiting the mobile receptacle and entering the environment.
    When the material has reached the desired level in the mobile container, the outlet valve of the silo is closed, stopping the loading process.
    Since most of the mobile receptacles have multiple loading holes to facilitate spreading of the material, that loading process may need to be repeated several times.
    In that case, the extraction tube with the device according to the invention is removed from the loading hole of the mobile container such that the mobile container can reposition itself, and the next loading hole is aligned with the extraction outlet of the silo to continue the loading process .
    After the mobile container has been loaded with the desired amount of particulate material, the extraction tube along with the apparatus is removed from the loading hole and disconnected from the outlet valve of the silo.
    After the mobile receptacle is completely filled, the mobile receptacle leaves the loading floor and is delivered to the client.
    In the meantime, the extraction tube is completely removed from the silo and the device according to the invention is disconnected from the extraction tube.
    This makes it possible to intensively clean both components independently.
    Since both the flexible chute and the rim of the device according to the invention are made of polyurethane which is approved for use with food (FDA or food compatible), they can be cleaned easily and quickly to prepare them for the next loading process.
    The collar provided on the distal portion of the sleeves is arranged to cover the loading opening of the mobile container, which prevents particulate material from being spilled during the loading process. If, for whatever reason, the operator of the mobile container accidentally moves the mobile container during the loading process, it will be the device according to the invention that absorbs the forces absorbing the forces and that bends or tears due to the flexibility of the said duct, instead of the extraction tube. If the forces were to be applied to the extraction tube, this could cause damage to the extraction tube and the silo to which it is connected, creating a hazardous situation for both the person carrying out the loading process and the person transporting the mobile container.
    In a preferred embodiment, the collar is a collar made of a transparent material, such as transparent polyurethane, which is approved for use with food.
    Accordingly, the person performing the loading process from the mezzanine level will be able to see through the transparent skirt of the flexible chute, to monitor the current level of grit material already in the mobile receptacle and to prevent that the mobile receptacle is overcharged - resulting in material spillage - or to prevent the charging process from stopping prematurely, which would not fill the mobile receptacle sufficiently.
    With the term 'particulate matter! within the scope of the present invention is meant any material of any origin, such as chemical, biological, mineral, agricultural material, in the form of a powder, gravel, granules or pebbles and having an average particle size from a few nanometers, such as 10 nm, to 10 cm or more.
    Advantageously, said particulate material is a granule material with an average particle size d50 which is between 1 mm and ó mm. That range of particle sizes of the particulate material allows a gravity loading process without using a more expensive pumping installation.
    Preferably, said mobile receptacle is a bulk receptacle or a tank receptacle which is transported by means of a truck or train. Said truck or train positions the loading opening directly below the outlet opening of said silo and transports the goods to a client after the loading process is completed.
    In a particular Embodiment according to the present invention, said flow connection is established by a mutual locking means arranged to connect said flexible chute to said extraction tube, at the distal portion of the extraction tube. This mutual locking means prevents an undesired uncoupling of the said extraction tube and the device according to the invention.
    In a preferred embodiment, the mutual locking means is a manually operated quick release locking means. This makes it possible to manually remove and/or mount the device to the extraction tube without the use of tools. This makes it possible to quickly mount the device on the required silos and to remove the device again for cleaning or for use in other silos.
    In a preferred embodiment of the present invention, said locking means comprises a first, male locking means adapted to be applied to an outer surface of said extraction tube, and a female locking means forming a through-hole through said wall of said extraction tube. including said flexible storage sleeve adapted to receive said male locking means.
    Said locking means simplifies the connection process of said device with said expiratory tube.
    This means that the disassembly can be carried out without too much complexity, but nevertheless allows a sufficiently firm connection between the extraction tube and the device.
    Such a locking agent offers an easy-to-clean solution, since very frequent cleaning is required to prevent contamination.
    The locking means also allows connection between the device according to the invention and another type of extraction tubes, and facilitates the process of moving the extraction tube between different loading holes, since they can now be moved as a single entity.
    Advantageously, said sleeve has a substantially cylindrical shape, said skirt mounted on the sleeve having a substantially annular shape with an inner circle in which the sleeve is received.
    Furthermore, since most of the loading inlets of mobile receptacles have a circular shape, it facilitates the set-up before the start of the loading process and provides better coverage of the loading hole during said process, avoiding gaps between the rim and the loading opening.
    In a particular Embodiment according to the present invention, said skirt mounted on the sleeve has a substantially conical shape, preferably a frustoconical shape, and is preferably made partly of a transparent material, e.g. with windows or completely transparent .
    This allows the person performing the lagging process to monitor the current level of material already in the mobile receptacle.
    Since most of these mobile receptacles have multiple loading holes to facilitate the spreading of the material to be loaded, it becomes more difficult to determine how much material can be loaded into each individual loading hole. The ability to monitor the current level of material present in the mobile container thus eliminates the need for a timer or expensive digital measurement tools, while still preventing material spillage during the process.
    Preferably, said collar is made of a flexible material which is approved for use with food, more preferably of polyurethane which is approved for use with food.
    In a preferred embodiment, said surface of said flexible chute is made of a polyurethane approved for use with food. Such materials have elastic characteristics, which prevent a sudden movement of the mobile receptacle, for example due to a communication problem between the person handling the loading and the person moving the mobile receptacle, from causing the extraction tube, or worse, , the silo itself is damaged. Instead, the least expensive part of the system will bend or tear, namely the device itself.
    In a preferred embodiment of the present invention, said sleeve comprises a lip projecting outwardly from the outer surface of the outer wall to which said terminal collar is connected, preferably welded or bonded to the sleeve, said lip being preferably between 0 and 15 cm, more preferably between 5 and 13 cm, and most preferably between 8 and 10 cm from the free end of the second portion provided to contact the lagad opening provided on said mobile receptacle. Said lip allows a rigid connection between the sleeve and the skirt, such that the device is resistant to daily wear and can be reused many times. The portion of the sleeve below the lip is brought into the charging hole during the charging process. Other embodiments of the device according to the present invention are stated in the appended claims. The present invention further relates to a storage and loading system comprising: a) at least one loading platform extending horizontally, said loading platform being arranged to be located below an outlet opening of at least one silo, preferably a vertical silo, wherein said outlet opening is adapted to be connected to a loading inlet on a mobile receptacle located below said loading platform, said loading platform further comprising at least one loading hole arranged to provide access to said mobile receptacle located below said loading platform is located, b) at least one extraction tube, with an upper end adapted to be connected to said outlet opening of said silo, and d) at least one device according to the invention.
    According to the present invention there is provided a system comprising a loading platform provided with at least one silo containing a particulate material to be dumped from the silo into a mobile container. As already explained, the silo comprises a vessel containing the particulate material, an outlet opening at the bottom of said silo for extracting said particulate material, and an extraction tube connected to and extending the outlet opening. When the mobile receptacle is to be loaded with particulate material, it reaches its loading position below the loading platform. Said loading platform allows mobile containers to pass underneath, which simplifies the positioning right under the outlet opening of the silo, without having to look out for the system supporting the silo. Said loading platform further facilitates access to the silos themselves for the person who has to carry out the loading process.
    The loading opening located in an upper part of the mobile container faces the outlet opening of the silo. The loading platform is provided with a through hole. The through hole, the loading opening and the discharge opening are aligned when the mobile receptacle is in its loading position. Said extraction tube allows a firm connection between the outlet opening of the silo and the loading hole of said mobile container.
    The system also comprises a device according to the present invention, the latter comprising a flexible chute having an outer wall surrounding a hollow body, adapted to be connected to a distal portion of said extraction tube with a mutual locking means, said flexible chute comprises a proximal portion and a distal portion, said proximal portion of said flexible chute being configured to surround said distal portion of said extraction tube, and said distal portion extends from said proximal portion and terminates at a free end of said flexible chute, said chute comprising a skirt connected to the distal portion of the chute and arranged to cover the loading opening on said mobile receptacle.
    The system according to the present invention is 'easy to operate' and safe.
    In the system of the present invention, the flexible chute is connected to the extraction tube, forming an assembly which passes through the loading hole of the loading platform.
    The three main elements are easy to connect and disconnect, while the collar connected to the distal portion makes it possible to cover said loading opening on the mobile container to prevent said particulate material from being spilled and released into the environment .
    The person performing the loading process is usually on the loading platform and is able to see through the transparent border of the flexible chute, to monitor the current level of particulate material already in the mobile receptacle and to prevent the mobile receptacle from being overloaded — which would cause material spillage — or prevent the filling process from stopping prematurely, resulting in insufficient filling of the mobile receptacle.
    Any material that is bounced upwards by impacting the mobile receptacle will bounce off the board and remain in the mobile receptacle, instead of leaving the mobile receptacle and ending up in the environment.
    When the material has reached the desired level, the outlet valve of the silo is closed.
    Since most of the mobile receptacles have multiple loading holes to facilitate spreading of the material, that loading process may need to be repeated several times.
    In that case, the extraction tube with the device according to the invention is removed from the loading hole of the mobile container such that the mobile container can reposition itself, and the next loading hole is aligned with the extraction outlet of the silo to continue the loading process .
    After the mobile container has been loaded with the desired amount of particulate material, the extraction tube along with the apparatus is removed from the loading hole and disconnected from the outlet valve of the silo.
    If, for whatever reason, the mobile receptacle operator accidentally moves the mobile receptacle while the extraction tube is still connected to the silo and goods are loaded into the mobile receptacle, it will, thanks to the presence of a flexible chute, the device according to the invention which absorbs the forces and which bends or tears.
    If the forces were applied to the extraction tube, it would cause massive damage to the silo and potentially endanger the person performing the loading process, which could be very harmful to the operator or cause costly damage to the industrial logistics provider .
    After the mobile receptacle is completely filled, the mobile receptacle leaves the loading floor and is delivered to the client.
    Meanwhile, the extraction tube is completely removed from the silo and the device according to the invention is removed from the extraction tube.
    This makes it easier to intensively clean both components to prepare them for the next charging process.
    In a preferred embodiment, the extraction tube is a telescopic extraction tube having an extended position and a retracted position.
    Those 2 positions make it easier for the person performing the loading process to place the extraction tube in the correct position.
    Advantageously, said system further comprises a loading wagon, said loading wagon comprising a stairway, a raised wagon platform and a Wheelbase, said loading wagon being adapted to be placed on said loading platform and to move thereon, and furthermore to gain access. up to the outlet opening of said silo, said loading carriage being further arranged to carry and transport said extraction tube to different positions on said loading platform. Thereby it is avoided that said extraction tube has to be carried and repositioned by hand, and furthermore its position is stabilized during the connection between said silo and said loading hole.
    In an additional variant, the system comprises a loading wagon, said loading wagon comprising a staircase, said loading platform and a wheelbase, said loading wagon being arranged to provide access to the outlet opening of said silo, said loading wagon being further arranged to carry and transport said expiratory tube to different positions above the loading inlet on said mobile receptacle Preferably, said mobile receptacle is a bulk receptacle or a tank receptacle transported by a truck or train, said mobile receptacle having a loading inlet wherein said loading hole is positioned right below one of the at least one through hole in said loading platform.
    More advantageously, said through-hole comprises a lp extending vertically upwards from said through-hole, said lip preferably having a height between 0 and 30 cm, more preferably between 15 and 25 cm. Said lip prevents any residues of material present on the floor of said loading platform from landing on the ground or in the mobile container, causing spillage. The lip has the same shape as the through hole, or some other shape enclosing the through hole.
    The present invention also relates to other embodiments of the system according to the present invention which are stated in the appended claims.
    Other features and advantages of the present invention are apparent from the following, non-limiting description, and from the drawings and examples.

    Figure 3 shows some of the possible variations of the system according to the invention.
    Figure 4 shows the locking means used in a preferred embodiment.
    In the drawings, like reference numerals are assigned to like or analogous elements.
    Detailed Description of the Invention As can be seen in Figure 1, the apparatus of the present invention comprises a flexible chute made of a material such as polyurethane which is approved for use with food. The flexible chute comprises a surface surrounding a hollow body 1, and a flexible skirt 2 connected to the end portion of said flexible chute. Said flexible board is made of a food approved material, such as food approved polyurethane.
    The device is connected to an expiratory tube 3, which comprises a male locking means 4 (i.e. a pin released from the extraction tube) inserted into the female locking means 5 which is attached to said surface surrounding a hollow body. The horizontal part of the U-shaped opening is closed by a vertical metal plate fixed with screws, thereby establishing a firm connection between said device and said extraction tube. The vertical space provided in the U-shaped opening in said female locking means 5 allows the male locking means to move in a vertical direction, enabling the device according to the invention to follow the vertical level of the goods that are transferred to a mobile container during the loading process. The extraction tube, with the apparatus of the present invention attached thereto, is then inserted through the through hole 6 provided in the loading floor of the multi-storey loading rig. When the charging process is complete, that through hole can be covered with a lid. Figure 2 shows an example of when the flexible chute is attached to the end portion of an extraction tube 3 during a loading process. The cover is now removed from the through-hole and the extraction tube is placed through said through-hole 6 together with the connected device. The upper part of the extraction tube is connected to a silo, and a loading hole of a mobile container is aligned with the through hole of the loading floor. Said loading hole is then opened and the lower part of the device according to the invention is inserted into said loading hole. The flexible edge then ensures that no material can be bounced upwards in the mobile container, thus preventing those goods from ending up in the environment.
    Because the flexible board is transparent, the person performing the loading process on the loading floor is able to monitor the level of particulate material in the mobile container and end the loading process at the right time.
    In order to further prevent the same amount of residues of material on the loading floor from entering the said multi-storey loading arrangement in the mobile receptacle which is located directly below the through-hole 6, a metal border 7 is provided around the through-hole, said border being equally spaced. whatever shape it can take, as long as it encloses the through hole.
    Figure 3A shows a schematic representation of a mobile receptacle 11 positioned directly below the silo, with both the outlet opening 10 of the silo and the loading hole 12 of the mobile receptacle 11 aligned along the vertical axis.
    The extraction tube 3 is connected to the outlet opening 10 of the silo 9. The flexible chute comprises a hollow body 1 and a flexible skirt 2, and is in flow communication with the end portion of said extraction tube covering the loading hole 12 of the mobile container 11 .
    Figure 3B shows a schematic representation of a mobile receptacle being loaded using the multi-storey system.
    The loading carriage 8 is located on the loading platform 12 which extends horizontally, said loading platform being arranged to facilitate access to both the loading hole of the mobile container and the loading outlet of the silo.
    The loading platform includes at least one through gate through which access is provided to the loading hole of the mobile receptacle.
    The loading hole of the mobile receptacle can then be opened directly from the loading platform, for example by means of a hook.
    The loading wagon 8 is supported by a wheelbase 18. The wheelbase 18 comprises a frame with at least four legs 19 and wheels 20 at the intersection of the legs 19 to allow a good movement of the loading wagon 8 on the loading floor 13 .
    As can be seen in Fig. 3B, the preferred loading carriage 8 is arranged to carry and transport said extraction tube 3 to different positions on said loading platform 13 .
    The extraction tube 3 is in flow communication with the device according to the invention, with a flexible chute 1 surrounding a hollow space and a flexible, preferably transparent border 2. The assembly of a loading carriage 8 and the expiratory tube 3 is particularly useful when the same expiratory tube has to be used. are used for different silos.
    As already explained earlier, there are usually several different silos on the loading floor, which contain different types of material.
    In such a case, it is particularly convenient to move the extraction tube on the loading floor to dump different types of materials into different mobile receptacles located on the ground floor.
    Since such extraction tubes are heavy and quite large to be carried by a human being, the fact that they are connected to and carried by the loading carriage makes the process of moving and unloading considerably easier.
    This makes it possible for the same extraction tube, device according to the invention and loading wagon to be used for unloading more than one recipient, thereby avoiding having to purchase a system per silo.
    The mobile container 11 itself is free to move on the ground floor, to position each of its loading holes directly below the through hole and the outlet of the silo.
    Figure 3C shows a schematic representation of the system when the loading carriage 8 comprises the loading floor.
    As can be seen, the loading carriage 8 comprises a staircase 17 which allows the operator to climb from the ground floor 18 on which the mobile container 11 is located to the loading platform 13 on the ground floor 18 . In that case, the loading vehicle is located on the ground floor.
    When the truck carrying the mobile container 11 is in its loading position, the mobile container is under the loading platform 13. The silo 9 has an outlet opening 10 and in its lag position, in the system, the outlet opening of the silo 10, the loading hole of the platform 6 and the loading hole 12 of the mobile container 11 are substantially aligned along a vertical axis to allow the particulate material to be deposited from the silo 9 into the mobile container 11 .
    The extraction tube 3 has a proximal portion 14 which, in the loading position of the mobile container 11, is connected to the outlet opening 10 of the silo 9.
    By the words "proximal portion connected to the outlet opening" it is meant that there is a flow connection between the extraction tube and the inside of the silo. In some examples it is possible to provide a physical connection where the extraction tube is fixed to the silo, for example by locking, by clamping or by screwing, but it is also possible to provide the extraction tube, provided with a hopper, simply under the outlet opening of placing the silo, without contact, but allowing the particulate material to flow from the silo into the extraction tube, under the influence of gravity, when the outlet opening of the silo is open.
    The distal portion 15 of the extraction tube 3 is provided in a preferred embodiment with a coupling means 4. The flexible chute 1 is provided with a mutual coupling means 5. The distal portion 15 of the extraction tube 3 is connected to the flexible chute 1 by a connection between the mutual coupling means 5 and the coupling means 4.
    Preferably, the excitation tube 3 is a telescopic extraction tube having an extended position and a retracted position.
    When the mobile receptacle is in the loading position, the extraction tube 3 is deployed in its extended position to establish a flow connection between the silo 9 to which it is connected and the loading hole 12 of the mobile receptacle 11 by means of the flexible chute 1 .
    In a preferred loading carriage 6 in the system according to the present invention, the horizontal portion defined by virtually connecting the four wheels 20 together is higher than the horizontal portion (i.e. the surface of the lag platform) of the loading platform 13 to increase the stability of the loading carriage 8.
    In another embodiment (not shown), the horizontal portion defined by Virtually Connecting the four wheels together is equivalent to the horizontal portion (i.e., the surface of the platform) of the platform.
    The frame typically comprises at least two vertical legs 21 and two inclined legs 22. The two inclined legs 22 are connected to each other by means of horizontal steps 23 which form the Tap of the loading carriage 8. Furthermore, the loading hole 6 comprises a lip 7 projecting upwardly from said loading hole 6, said lip 7 preferably having a height between 0 and 30 cm, more preferably between 15 and 25 cm. The loading carriage 8 of the system according to the present invention not only facilitates the transportation of said extraction tube, but also provides better access to a silo 9. The proximal portion 14 of the extraction tube 3 is placed either directly below the outlet valve of a silo 9, or associated therewith, said silo comprising particulate material to be dumped and further transported to clients. When the mobile container 10 is placed directly below the loading platform, with the loading opening 11 of said mobile container 11 directly below the loading hole 12 through which the extraction tube 3 is inserted, the particulate material in the silo 9 will pass through the outlet opening 10, the extraction tube 3, the device according to the invention and the loading inlet 12 in the said mobile receptacle 11, and finally end up in the mobile receptacle 11. Said extraction can take place either under the influence of gravity or by means of a pump.
    In Figure 4, (a) is a representation of the female locking means to be attached to a preferred embodiment of the device according to the invention. The female locking means consists of a metal plate with a cut-out U-shape. Said female locking means is to be fixed by screwing through the fixing holes 25, to the flexible chute or to the extraction tube, while the male locking means — which is preferably a flat-headed metal stud having a dimension greater than the largest dimension of said U-shaped cutout — is connected by welding or gluing to the other part. The male locking means should be slid into the U-shaped extrusion mold. The connection can be secured by means of an additional metal component which is connected between the two holes 26a and 26b. Said metal component, which can be seen in Fig. 4(b), is screwed onto the female locking means by inserting screws through holes 27a and 27b and blocking the horizontal part of the U-shaped cutout. This allows the male locking means to move along the vertical axis and allows the device according to the invention to move with the increasing volume level in the mobile receptacle.
    If the mobile receptacle makes a sudden movement, for example as a result of a communication breakdown, the locking means enables the device according to the invention to also perform a small rotation, which causes the device to 'jump' out of the loading hole, causing damage to the extraction tube and the silo is avoided.
