专利说明:
[0001] The present invention relates to an excavator aspirator. Such a public works machine is conventionally constituted by a carrier vehicle on which are mounted a machine compartment 5 equipped with bodies for pumping waste and rubble and a tank subdivided by a partition into a filter compartment adjacent to the compartment machine in which is mounted a filter lining comprising a series of dust filters, and a storage compartment of waste and vacuumed rubble equipped at its rear part 10 with an articulated suction arm connected to a suction circuit connected to the suction side of the pumping devices. The tank of such an excavator aspirator can tilt transversely about a horizontal tilt axis substantially parallel to its median longitudinal axis between a rectified position or working position in which the waste and the rubble can be sucked and transferred to the storage compartment, and on the other hand a tilted position or emptying position. Excavator vacuumers of the aforementioned type can advantageously be used in the context of many activities such as digging trenches on roads or in urban areas without the risk of deterioration of the underground pipes, or to suck rubble on terraces or in the upper part. buildings, or to perform snow removal operations. The tank of excavator vacuums currently available on the market is closed at its upper part by a large cover hinged thereto which extends over the entire storage compartment and the filter compartment. The articulated vacuum arm is directly connected to this large cover which encloses most of the suction circuit. As a result, in order to drain the accumulated waste and accumulations in the storage compartment and under the filters it is necessary to lift the large lid before tilting the tank so as to disengage the upper part of the storage compartment and filter compartment. [0002] This necessity implies that it is possible to have a high height above the vehicle that is not always available, for example in the presence of electrical conductors or trams. In addition, dust entrained with the sucked air can be retained on the lid and then fall on the tank and the filter lining, which is not protected at this level, clean air side. Another disadvantage of excavator aspirators of this type is related to the fact that the filter liner is only difficult to access and that the maintenance and replacement of filters 10 require to lift the large lid, which is impractical. It is also very difficult to perform the operations of replacing and cleaning the inner parts of the lid and in particular the inlet port of the pumping channel. The object of the present invention is to provide an excavating suction pump which makes it possible to remedy these drawbacks. According to the invention, the upper part of the tank of this excavator aspirator is subdivided longitudinally into a closed part, below which is mounted at the storage compartment, a longitudinal section of the suction circuit connected to the arm as - Pirateur 20 articulated, and an open part closed by a hinged longitudinal lid which is open when transferring the tank from the working position to the emptying position to allow the evacuation of waste and rubble collected in the compartment of storage and dust collected in the filter compartment. According to the invention, the tank advantageously has a rounded portion at the bottom, making it easier to empty the waste and the rubbish and to improve its vacuum resistance. The excavating aspirator which is the subject of the invention is thus distinguished from machines of this type currently on the market by replacing the large lid to be lifted before tilting the vessel by a small longitudinal cover extending along a closed portion over the entire length of the tank, that is to say, the upper part of the storage compartment and the filter compartment. [0003] To this longitudinal cover which is open when the tank is tilted, is added a hinged protective cover which covers the filter lining and remains closed during the tilting of the tank from the working position to the emptying position. [0004] This protective cover, which extends laterally to the longitudinal cover, is only open during the operations of handling and replacing the filters, which are thus greatly facilitated, all the more so as it can advantageously be provided to facilitate access to the filter lining a secure platform including a caille- leis fixed to the front part of the tank and equipped with a railing formed by the rear part of the machine compartment. It should be noted that as part of this presentation, the terms high, low, lower, upper ... refer to the excavator aspirator straightened in the working position while the terms front, rear must be included in the direction from the driver's cab of the carrier vehicle to the articulated vacuum arm. Another essential difference between the currently claimed excavator and the machines of the same type currently on the market is related to the fact that the articulated suction arm is not mounted on the lid, but directly on the tank, upper part of it at the rear part of the storage compartment below the fixed part. Due to this arrangement, it is necessary to equip the excavator aspirator according to the invention with connection members for disengaging the tank and the suction circuit of the articulated vacuum arm and the pump members mounted in the compartment. machine when moving this tank from the working position to the emptying position, and re-coupling them during the reverse movement to allow the suction of waste and rubble. [0005] Such connecting members have the advantage of enabling the discharge orifice of the waste and rubble of the articulated vacuum arm to be released and the inlet for this waste and rubble in the tank when the latter is tilted to the emptying position so as to clean these orifices which are frequently clogged with fat soil entrained with the sucked air. [0006] In order to make it possible to visualize the clogging state of the abovementioned orifices and to facilitate their cleaning when they are uncoupled, a gateway facilitating access to these orifices may advantageously be mounted on the tank at the rear part of the storage compartment. [0007] According to another characteristic of the invention, the longitudinal section of the suction circuit located below the closed portion at the storage compartment comprises a pumping channel of waste and rubble connected to the articulated vacuum arm and an air suction channel connected to the suction side of the pumping members. This air suction channel is mounted laterally adjacent the pumping channel of waste and rubble parallel thereto and has an air passage opening at its rear end. [0008] The air enters the storage compartment of the tank with the waste and rubble is precipitated at the bottom of this compartment; the air is sucked upwards parallel and enters the air intake channel through the passage opening at the rear end of this channel causing the fine dust. [0009] According to a preferred feature of the invention, the air suction channel has a substantially U-shaped section and comprises a central branch and two lateral branches, one of which is fixed to the longitudinal cover at its end. As a result, when the longitudinal cover is open, the lateral branch of the air suction channel thus fixed to this cover is driven with it to clear this channel, and the dust entrained with the sucked air can be evacuated during the switchover. of the tank in the emptying position. According to another characteristic of the invention, the air suction channel extends into the filter compartment by a suction pipe extending from top to bottom and laterally in front of the partition separating the storage compartment from the compartment. filtering along the filter lining, then through this lining and at the outlet thereof by a collection chamber connected to the suction side of the pumping members. [0010] It should be noted that the filter compartment can advantageously be equipped, in front of the partition wall, a baffle partition of the air flow. The air leaving the air intake channel through an outlet opening 5 and passing through the suction line thus passes below and on the sides of this baffle wall. The filters fitted to the filter lining are thus traversed from bottom to top by the sucked-up air and the clean air freed of dust leaves the tank in the upper part at the front thereof, to be transferred to the machine compartment. towards the suction side of the pumping devices. The dust that is drawn into the suction line by the sucked air is collected in a dust accumulation chamber located below the filter pad. According to a particularly advantageous characteristic of the invention, this dust accumulation chamber extends upward along the filtering lining by a draining passageway opening at its upper part by a dust discharge opening which is 20 located in line with the extension of the longitudinal cover at the filter compartment. As a result, after opening this longitudinal cover and tilting of the tank to the emptying position, the dust collected in the dust accumulation chamber is discharged from the tank 25 with the waste and rubbish collected at the lower part of the compartment. storage. According to another characteristic of the invention, the protective cover covering the filter lining is equipped with filter de-clogging members by counter-current compressed air supplied by an air compressor. This declogging may advantageously be carried out intermittently according to an automated cycle. It should be noted that in the working position as in the emptying position the tank rests on telescopic crutches equipped at their lower part with support cylinders on the ground so as to relieve the wheels of the carrier vehicle. These crutches are advantageously three in number, namely: - one at the rear, right side, - one at the rear, left side, one between the machine compartment 2 and the tank 3 side tilt axis of the tank. When the vacuum arm is used the two crutches are lowered. When emptying, the two side stands are lowered. According to another characteristic of the invention, the rear stand located at the rear right side and supporting the articulated arm is equipped at its upper part with an axis welded to it and coming to be inserted at the end. the tilting of the tank between the emptying position and the working position in the attachment parts attached to the rear part of this tank. This coupling makes it possible to make the rear stand solid with the bowl to prevent it from bending when using the articulated suction arm. According to another characteristic of the invention, a connecting member movable in rotation about an axis and controlled by a jack makes it possible to quickly disconnect the pumping channel from the waste and rubble and the articulated arm to allow the tilting of the tank. The characteristics of the excavator aspirator which is the subject of the invention will be described in more detail with reference to the accompanying non-limiting drawings in which: FIG. 1 is a perspective view of the excavating aspirator, FIG. is a perspective view of the excavator aspirator from another angle, the filter protection cover being open and the upper part of the machine compartment removed, Figure 3 is a perspective view of the excavator suction tank in the emptying position representing the upper part of this tank, open longitudinal cover, - Figure 4 is a partial section of the tank of the excavator aspirator representing the pumping channel of waste and rubble, Figure 5 is a view in perspective similar to Figure 4 but showing the air suction channel, Figure 6 is a partial sectional view of the storage compartment at part a Figure 7 is a partial section of the front part of the excavator suction tank, at the level of the filter compartment, Figure 8 is a detail showing the hooking of the rear stand with the tank. According to FIG. 1, the excavating aspirator is constituted by a carrier vehicle 1 on which are mounted by moving from the front to the rear of this vehicle a machine compartment 2 equipped with bodies for pumping waste and rubble are not shown in the figures and a tank 3, the lower part 4 has a rounded shape. The tank 3 is subdivided by a partition wall 28 from its front part to its rear part into a filter compartment 5 adjacent to the machine compartment 2 and a storage compartment 20 6 waste and rubbed material. The filter compartment 5 is equipped at its inner part with a filtering lining 7 comprising a series of filters 8 which are visible in FIGS. 4 and 7. The storage compartment 6 is equipped at its rear with an articulated vacuuming arm 9 shown schematically in Figures 1 and 2 which is also visible in Figure 3. This articulated arm 9 is connected to a suction circuit connected to the suction side of the pump members mounted in the machine compartment 2. The characteristics of this suction circuit will be described in more detail later in this presentation. The vessel 3 may tilt transversely about a horizontal lateral tilting axis 10 parallel to its median longitudinal axis between a rectified position or working position shown in Figures 1, 2, 4, 5 and 6 in which waste and rubble can be sucked and transferred to the storage compartment 6 and a tilted position or drain position shown in Figures 3 and 7. The tilting of the tank 3 about the axis 10 between the working position and the drain position is controlled by double-acting cylinders 16 whose attachment shafts 17 are located vertically to the bearings of the tilting axis 10. The upper part of the vessel 3 is subdivided longitudinally into a closed fixed part 11 and a open portion closed by an articulated longitudinal cover 12 which extends over the entire length of this tank at the filter compartment 5 and at the storage compartment 6 This longitudinal cover 12 is open during the transfer of the tank 3 from the working position to the emptying position to allow the evacuation of waste and rubble as well as dust as shown in FIG. longitudinal 12 is controlled by cylinders 15. According to Figures 1, 2 and 3, the filter compartment 5 is further open at its upper right to the filter lining 7 and 20 equipped at this level with a hinged protective cover 13 whose displacement is controlled by a cylinder 14. This protective cover 13, which extends laterally to the extension of the longitudinal cover 12 at the filter compartment 5, remains closed during the tilting of the vessel 3 of the working position at the emptying position as shown in Figure 3. According to Figures 4, 5 and 6, a longitudinal section 18 of the suction circuit is mounted in the upper part of the storage compartment 6 below the closed portion 11 of the tank 3. This longitudinal section 18 comprises a pumping channel 30 of waste and rubble 19 and an air suction channel 20 mounted laterally in the vicinity of this pumping channel. waste and rubble 19 parallel to this channel. According to FIG. 3, the pumping channel for the waste and rubble 19 opens at the rear part of the tank 3 through an inlet orifice in this tank 21 which is connected to the outlet orifice 22 of the articulated suction arm 9. According to FIG. 8, a connecting member 23 movable in rotation around an axis 43 and controlled by a jack 24 makes it possible to deactivate the orifices 21 and 22 and as a result to rapidly disconnect the pumping channel from the waste and the rubbish 19 and the articulated arm 9 to allow the tilting of the tank 3. A bridge 30 mounted to the rear part of the tank 3 which is visible in Figures 1, 3 and 4 allows, when the inlet port 21 of the channel pumping waste and rubble 19 and the outlet port 22 of the articulated vacuum arm 9 are cleared to view the waste contained in the storage compartment 6 and to rid these holes of the earth and sticky materials having been there agglomerate. Similarly and again to allow the tilting of the tank 3 between the working position and the emptying position, there are provided at the front of this tank connection members 25 controlled by a jack 26 which can uncouple the circuit In FIGS. 4, 5 and 6, the air intake channel 20 which is connected to the suction side of the pump members mounted in the machine compartment 2 has a U-shaped section and comprises a central branch 31 and two lateral branches 32, 32 'one of which 32' is adjacent to the pumping channel of waste and rubble 19. The air intake channel 20 has an air passage opening 33 at its rear end. The air enters the storage compartment 6 of the tank 3 with the waste via the inlet port 21 of the pumping channel 19 and the sucked rubbish is precipitated at the lower part of this storage compartment 6. 30 L' air and the fine particles contained in the waste enter the air intake channel 20 through the passage opening 33 before leaving this channel 20 in the filter compartment 5 through an opening 34 visible in FIG. 4 According to FIGS. 1, 5 and 6, the lateral branch 32 opposite the pumping channel of the waste and rubbish 19 of the air intake channel 20 is fixed to the longitudinal cover 12 at its end so that this channel is released when opening the longitudinal cover 12 as shown in Figure 1 to allow the evacuation of dust that may have been entrained with the air sucked during the tilting of the vessel 3. According to Figures 4 and 5, the air loaded with dust that penetrates in the filter compartment 5 through the outlet opening 34 of the air suction channel 20 is transferred into a suction line 35 extending this suction channel 20 beyond the partition wall 28 of the storage 6 and the filter compartment 5. This suction pipe 35 extends from top to bottom at the front of the partition wall 28. At the outlet of the suction pipe 35, the air circulates laterally and goes back towards the upper part of the tank 3 through the filters 8 equipping the filtering lining 7, and then the clean air freed of dust is transferred into a collection chamber 36 visible in FIG. 7 which is connected to the suction side of the Pumping mounted in the machine compartment 2. Upstream of the filter pack 7, the dust entrained with the sucked air is collected in a dust accumulation chamber 37 visible in FIGS. 5 and 7 which is located below 7. According to FIG. 7, the dust accumulation chamber 37 extends upwards along the filtering lining 7 by a draining cowl 38 opening at its upper part through an opening of emptying 39 also visible in Figure 3. This emptying opening 39 allows the evacuation of the dust contained in the accumulation chamber 37 when the tank 3 is transferred to the emptying position, as shown in Figure 3. As shown in FIG. In particular in FIG. 3, the hinged cover 12 extends at the level of the filter compartment 5 to the right of the dust discharge opening 39 so as to close it in the working position. [0011] This extension of the longitudinal cover 12 is directly adjacent to the protective cover 13 closing the filter lining 7. As already indicated, the protective cover 13 5 is closed both in the working position and in the emptying position and n ' is open only to allow the maintenance of the filter lining 7 and the replacement of the filters 8 equipping this lining. According to FIGS. 1 and 2, access to the filter lining 7 is facilitated by a secure platform 40 constituted by a grating fixed on the tank 3 and by a railing defined by the rear end of the machine compartment 2 Furthermore, in the working position and in the emptying position, and according to FIGS. 1 and 2, the carrier vehicle 1 rests on telescopic stands 41 equipped at their lower part with support cylinders 15 not shown on the the figures that help relieve the wheels. These crutches 41 are three in number, namely: one at the rear, right side, one at the rear, left side, one between the machine compartment 2 and the tank 3, on the rocking side of the tank. According to FIG. 8, the tank 3 is equipped at its rear part with hooking pieces 42A in which an axle 42B integral with the rear stand 41 located at the rear right side and supporting the articulated arm 9 is inserted respectively. at the end of the tilting of the tank 3 between the emptying position and the working position. This coupling makes it possible to make the rear stand 41 integral with the tank 3 to prevent it from bending during the use of the articulated suction arm 9.
