    [0004] OBJECT OF THE INVENTION
    [0006] The object of the present patent application is an amphibious dredging machine, according to claim 1, which incorporates notable innovations and advantages over known similar machines.
    [0008] BACKGROUND OF THE INVENTION
    [0010] At present, most of the sedimentary basins of the Levant and South of Spain have serious problems of silt sedimentation in their natural channels. As such they are understood, either the rivers that cross clay, silty, sandy soils, etc., or the dams and reservoirs, where the natural channels are intercepted by these infrastructures. This situation also occurs in other irrigation infrastructures, such as canals and ponds. To these sedimentation problems must be added others, such as the presence of invasive species (zebra mussel, bushes, algae, etc.), which also affect riverbeds and channels.
    [0012] Said sedimentation in reservoirs, canals, irrigation ponds, etc., are currently posing a serious problem for the exploitation of infrastructures. Some of the most common drawbacks are those related to the reduction of the transport and storage capacity in a situation of high river level, and also with collapse due to blockages and continuous cleaning of seeps in low level river distributions, such as drips, seeps , etc.
    [0014] Various public entities and organizations have been trying to find solutions for years, without satisfactory results to date. Thus, the infrastructures in some areas are at the limit, or almost unused, due to the problem of sedimentation. This sometimes requires the carrying out of emergency works, or the public bidding of tenders that solve the problem, without obtaining profitable solutions, or that present adequate economic returns.
    [0015] Several technical developments focused on alleviating the problem are known in the market, such as static suction and pumping mechanisms, manual extractions by means of various machinery, microwave systems for disintegrating the sedimentation and subsequent hydraulic vehicle, and dredging systems, with more or less automation and / or performance.
    [0017] In this regard, it is known from the state of the art, as described in document WO9947758, a machine for carrying out work on land and / or in water comprising a frame that moves on wheels, a platform body in the upper part frame, an extension arm attached to the lower frame that rotates relative to the lower frame and deck body, and a work implement attached to the extension arm. The machine features a telescopic extension arm, at the end of which removable work implements can be attached. A platform body can move along the length of the lower frame, and a front edge on the platform body is essentially open, in order to allow loading and unloading of material.
    [0019] It is also known from the state of the art, as described in document CN2934365, a four-wheel amphibious hydraulic excavating and cutting machine with self-adjusting floating box type caterpillar track. It has buoyancy advantages, and the relative pressure on the ground is small, as well as the resistance in driving. Moreover, the driving force is large, and the service life is long. It comprises a power unit that is mounted on a cart, being connected to a working mechanism. The cart is mounted on two floating boxes on the two sides. It comprises a caterpillar is mounted on each floating box. A chain wheel guide and a tensioning mechanism are arranged at the front of each floating box. A drive chain wheel mechanism is arranged at the rear of each floating box. The drive chain wheel mechanism builds a four-wheel drive structure. Features one or more integrated speed reducer hydraulic motors at both ends of the drive chain wheel shaft.
    [0021] The object of the present invention is to overcome the aforementioned problems, presenting an efficient equipment that replaces obsolete river and port maintenance systems in the extraction of sludge and silt that cover natural and man-made hydraulic pipelines. It is also intended to achieve a superior extraction performance, additionally counting with amphibious capacity, which allows the machine work from land or submerged, according to the specific needs that arise.
    [0023] BRIEF DESCRIPTION OF THE INVENTION
    [0025] The present invention refers to a machine whose objective is to present an efficient equipment for river and port maintenance, in particular in the function of extracting sludge and silt that cover natural and man-made hydraulic pipelines. It is intended to obtain an extraction performance superior to the alternatives on the market, counting in turn with amphibious capacity, which opens the possibility of working, either from land, or submerged, depending on the needs of the specific river area. Thanks to its adaptability to the particular situation of each infrastructure, and its amphibious capacity, it can adapt to the geometry of the riverbed, canal, pond or reservoir. The possibility of operating, both from within the channel or reservoir, as well as from its margins, allows cleaning the deepest and inner areas, a situation that is impossible with a backhoe. Thus, this multipurpose self-propelled amphibious equipment represents a technological innovation for the maintenance and cleaning of the bottoms of rivers, canals, ponds, reservoirs, etc., and in the dredging of marinas and in the extraction of sludge in irrigation ponds. , wastewater and mining.
    [0027] In other words, the objective of the present invention is to present a dredging machine or equipment intended to alleviate, if not to solve, one of the serious problems of irrigation channels and infrastructures in clay, silty and sandy areas, with the environmental objective of returning to their original location the muds and silts dragged by erosion, returning to enrich the land by replacing them. This work allows a restoration of the slopes and fields attached to rivers, canals, ponds, reservoirs or ports.
    [0029] Therefore, its activity respects the environment and collaborates in the maintenance and conservation of the margins of said infrastructures, returning the intercepted sludge to the original slopes, providing nutrients to the adjacent crop fields.
    [0031] Therefore, an integral environmental solution is presented, not only with the extracted sludge, but also with the removed biomass, being able to clean the riverbed by working from the riverbed itself, in flotation. Specify that the biomass is preferably shredded, with a frontal brush cutter, being later poured either into a container, or into a storage area. This biomass can later be used in the construction of dikes, thus retaining the sediments on the slopes where the sediments are discharged for the restoration of fertile soil.
    [0032] The possibility of taking advantage of the extracted sediments and sludge, rich in nutrients, can be achieved thanks to means such as a pump and hoses that can deposit it in the fields required by farmers in the contour of the river environment.
    [0034] Also from a social point of view, advantages are achieved such as the creation of jobs in the design, manufacture and operation of the machine; the increase in yield in the cultivated fields where the sludge is deposited, improving their agricultural capacity; the restoration of slopes and fields attached to these channels affected by erosion, promoting in some way the recreational activity associated with them.
    [0036] Thus, and more specifically, the amphibious dredging machine of the present invention comprises an upper platform, and a lower platform connected with at least one first dredging means, wherein said lower platform comprises means for moving the amphibious dredging machine , and wherein the upper platform is connected to the lower platform through extensible clamping means, so that the distance between the upper platform and the lower platform is adjustable. In this way, in a first support situation of the lower platform on the river bed, the upper platform can be kept above or above the water level. And in a second situation of flotation of the machine, and of maintenance of the upper platform on the bathymetric plane, the lower platform can be raised above the river bed, staying on it at the distance that is considered most adequate for an efficient work of the dredging means, being able to even regulate the pressure that the lower platform, or the dredging means, exert on the river bed, in order to achieve optimum efficiency in the dredging work.
    [0038] Thus, the support on the sediments of the river bed can be regulated, for example, by placing the lower platform in a semi-suspended state within the aquatic environment, which allows the machine to be kept in a uniform bathymetry and is not affected by jumps or jumps. bottom holes at different depths. Thus, the amphibious dredging machine can both work in support or by flotation, depending on the topographic or bathymetric needs, extracting from 200 to 1500 m3 / h of sediments (m3 equal to lamina bathymetry sediments), evacuating the sediments in the form of pulp, with sediment concentrations of 30-60%.
    [0040] It should be further specified that, in a particular embodiment, the displacement means move the upper platform. Thus, said means of movement, even being located on the lower platform, can cause the upper platform to move as there is between both platforms, upper and lower, an adjustable and / or extensible mechanical linkage or connection, although capable of being arranged in a rigid configuration.
    [0042] More in particular, the extensible clamping means of the amphibious dredging machine comprise a scissor mechanism, so that the distance between the upper platform and the lower platform is adjustable and / or extensible, the upper platform being at the same time clamped and / or or supported on the lower platform in a robust and reliable way. By means of said scissor mechanism, operation is possible horizontally to the bathymetric plane, with total control of the support on the bottom, or alternatively, at the working depth and pressure level on the river bed that are determined as optimal. .
    [0044] In a preferred embodiment of the invention, the amphibious dredging machine comprises a first mechanical element for connecting the lower platform with the extensible clamping means, so that both elements are mechanically linked or connected, and in a sufficiently robust way for the machine operation.
    [0046] According to another aspect of the invention, the first dredging means comprise suction means, intended for cleaning sludge by suction. Said suction means preferably comprise suction nozzle or dredging nozzle with rotor, in order to regulate the suction capacity, which presents a high performance in relation to energy consumption, being in an order of five times of the offered performance. by other machines known from the state of the art. Advantageously, and with a view to better cleaning, the first dredging means can comprise an auxiliary pump that expels water under pressure over the river bed. Optionally, the suction nozzle can have means of orientation of the working angle, in order to improve the efficiency of the cleaning operation, depending on the consistency of the layer of mud and the residues present in the riverbed.
    [0047] Advantageously, the amphibious dredging machine comprises second dredging means, wherein said second dredging means comprise stripping means. In this way the machine, when working in open waters and in channels, can intercept, in its function of extracting mud, foreign bodies such as stones, trees, debris, etc. located within the mud itself. Thus, and to avoid problems with these hard bodies, it is possible to implement optionally, said brushing means, type rotary rake-punch, in the forward position, according to the direction of advance of the machine, with the mission of carrying out a forward sweep to remove foreign bodies, protecting the suction nozzle from clogging.
    [0049] Thus, and for the aforementioned purposes of protecting the first dredging means, which are preferably suction means, against jams and blockages, the second dredging means are located ahead of the first dredging means according to the direction of movement of the machine. Consequently, the second dredging means is preferably located at the front of the dredging machine, and the second dredging means is preferably located at the rear.
    [0051] According to another aspect of the invention, the first dredging means and / or the second dredging means comprise a second mechanical connection element with the lower platform, so that both are mechanically linked in a robust and reliable way to the main structure of the machine.
    [0053] Advantageously, the first mechanical connection element and / or the second mechanical connection element have at least one degree of freedom of rotation. In this way, the advance of the machine is made possible by the means of movement on inclined and sloping river beds. And it is also possible, on the other hand, to adapt the working angles of the first dredging means and / or the second dredging means to the different roughnesses and inclinations of the bottom or riverbed.
    [0055] More specifically, the at least one degree of freedom of rotation is with respect to an axis parallel to the direction of travel of the machine and / or with respect to an axis perpendicular to the direction of travel of the machine. In this way, the upper platform can maintain horizontality on the bathymetric plane, the extensible fastening means being able to maintain verticality, despite the fact that the floor of the bottom or river bed presents inclinations, both lateral and frontal.
    [0056] In a preferred embodiment of the invention, the amphibious dredging machine comprises a geopositioning system, which makes it possible to determine the position of the dredging machine, and its location in a plane of the geography of the fluvial environment through which the machine is moving. . Preferably geopositioning system is a GPS type system, optionally including an antenna. In this way, precision in work is improved, maximizing the efficiency of cleaning and treatment tasks.
    [0058] On the other hand, it should be mentioned that the means of movement are a mechanical caterpillar, so that the dredging machine is enabled for a land movement, having a caterpillar track to support and advance on the ground.

Said fin has a preferably concave shape on the inside, so that when the track rotates in an aquatic environment, the fin pushes the water back with a high resistance on the underside of the mechanical track tread, while, on the upper side of the mechanical track tread, the resistance is lower, as the fin has a convex shape on the outside.
    [0062] According to another aspect of the invention, the upper platform comprises flotation means, so that the dredging machine has an amphibious capacity. Said flotation means have a flotation module that allows the machine to move in float with a draft of up to 800 mm and a net load capacity of up to 16,000 kg, also making it possible to drag a pipe and an electric cable of autonomous way.
    [0064] Additionally, the upper platform comprises means for extracting waste from the river bed, in order to be able to remove said waste elements from the river environment. Optionally, the extraction means can be an extraction clamp or crane, in order to better transport the waste to a container, or storage area. Preferably the extraction means are located in the upper part of the upper platform.
    [0066] According to another aspect of the invention, the dredging machine comprises a contact sensor that detects when the lower platform makes contact with a river bed. In this way, the extensible clamping means can be adjusted with greater precision, properly adjusting the distance between the upper deck and the lower deck. Specifically, the probe transmits the vibration collected by an accelerometer to a control screen located in the accommodation for the operator who operates the machine, warning that the riverbed has been touched.
    [0068] Preferably, the first dredging means and / or the second dredging means are actuated by hydraulic transmission means, orienting and positioning said dredging means in the most adapted way possible to the river bed. Said hydraulic transmission means are preferably hydraulic pistons. The hydraulic transmission means are hydraulically connected to at least one hydraulic pump, so that they are hydraulically powered. Said at least one hydraulic pump is mechanically connected to at least one heat engine.
    [0070] It should be noted, on the other hand, that the upper platform comprises a cabin or housing for at least one operator, so that the dredging machine can be operated and operated in a comfortable and efficient manner. Said cabin or accommodation for the operator comprises a series of control means that make it possible to regulate and control the different parameters of the machine.
    [0072] The control means can comprise electrical and electro-hydraulic controls, a plotter or plotter with a probe to see in real time the background that is being worked on and a GPS screen intended to be viewed by the person operating the machine. In this screen you can trace the path of the machine for a better orientation of the operator. Said control means may also comprise a screen with the graphics of the position of the first dredging means (suction nozzle) and / or second dredging means (bucket with rake). Optionally, the machine can have means for adjusting the advance, as well as regulating the revolutions of the suction nozzle drum. The graphic display can show a revolution counter, a temperature gauge for the heat engine, controls for the advance adjustment and the revolutions of the suction nozzle drum.
    [0074] It should be mentioned that the first dredging means and / or the second dredging means can be electrically powered, and that the first dredging means is preferably connected to at least one sludge extraction pipe, so that it can be transported to another point. distant the extracted material. Additionally, the dredging machine has a series of means for dragging the pipe and the electric cable, so that they do not interfere with the forward and maneuvering movements. Sayings Forward and maneuvering movements are facilitated by floating means, which are, optionally, pontoons connected with practicable articulated joints, which can be separated from the upper platform by removing connecting bolts.
    [0076] On the other hand, the machine can have a support and flotation wheel, with support and hydraulic cylinder, which serves to bridge differences in level and sediment banks, being controlled from the cabin or housing with an electrohydraulic control. There are also a series of wheels in the corner of the pontoon, to push the floating pipes, and that they are not damaged. In the lower part you can see a wheel, preferably metallic, at the vertex of the bottom of the pontoon, to avoid snagging in the concrete of the bottoms.
    [0078] It should be noted that the machine can advance by pulling the extraction means that go on the machine, optionally including a winch. It can have 1000 meters of steel cable and a towing capacity of 5000 kg. Said winch will also be used for the extraction of bodies held by the front rake, with a hydraulic clamp installed at the tip of the winch cable.

The first dredging means (21) are in a suction operation of the sludge or residues (91) from the bottom. For their part, the second dredging means (22) carry out a preliminary task, according to the direction of travel, of clearing and cleaning solid elements that could block the first dredging means (21). In the upper part, the extraction means (23) are observed in a collected position on the cabin or housing (81) for the operator (82). The displacement means (3) are supported on the river bed (9), specifically by means of the mechanical track (31) and its fins (32). The extendable clamping means (4) are in an intermediate position, neither retracted nor fully extended, according to the necessary distance, so that the upper platform (11) is at the bathymetric level of the river surface, and the lower platform (12) rests on the river bed (9). In this situation, the flotation means (5) only partially exert their function as there is a mechanical support on the bottom. The hydraulic transmission means (73) are also in an intermediate extension position, being hydraulically powered from a hydraulic pump (72) activated by a heat engine (71). Behind the dredging machine you can see the pipe (74) for evacuating the sludge and waste (91) absorbed by the first dredging means (21), together with an electric cable (75) feeding the different electrical devices .
