The installation end of multistage expansion bracket 10 is connected with the drive roll subassembly 20 that rotates the setting, and the cantilever end of multistage expansion bracket 10 is connected with the driven voller subassembly 30 that rotates the setting, and around being equipped with the conveyer belt 40 that is used for carrying the material on drive roll subassembly 20 and the driven voller subassembly 30, multistage expansion bracket 10 is located and is enclosed the annular ring that establishes and form by conveyer belt 40. The driving roller assembly 20 is connected with a driving assembly 50, and the driving assembly 50 is used for driving the driving roller assembly 20 to rotate so as to move the conveyer belt 40 under the driving of the driving roller assembly 20 to convey the material after the multi-stage telescopic frame 10 extends to the proper position and tensions the conveyer belt 40.
Before the vehicle-mounted butt joint conveying device works, the device retracts into a carriage 130 of vehicle-mounted equipment, when materials need to be conveyed, a multi-stage telescopic frame 10 automatically extends along the material conveying direction and extends into the carriage of the butted vehicle-mounted equipment, or extends into the carriage of the butted vehicle-mounted equipment under the action of manual pulling force, when the multi-stage telescopic frame 10 extends to the limit position, a conveying belt 40 is tensioned on a driving roller assembly 20 and a driven roller assembly 30, then a driving assembly 50 acts to drive the driving roller assembly 20 to rotate, the driving roller assembly 20 drives the conveying belt 40 to move and the driven roller assembly 30 to synchronously rotate when rotating, so that the conveying of the materials placed on the conveying belt 40 is realized, after the conveying of the materials is finished, the driving assembly 50 stops driving, and the multi-stage telescopic frame 10 automatically or manually retracts into the carriage 130.
The vehicle-mounted butt-joint conveying device of the invention retracts into the carriage 130 when not in operation, does not influence the normal running and the external appearance of the vehicle-mounted equipment, when the unloading is required, the material can automatically extend out or extend out under the action of manual tension and extend into a carriage of the butted vehicle-mounted equipment, thereby forming a typical material conveyor for unloading or seamless docking with the docking vehicle-mounted device, thereby greatly reducing the working intensity of unloading operators, reducing the cost of manpower and material resources required by the unloading operation, does not affect the health of the unloading operators, can greatly improve the unloading efficiency, prevents the materials from splashing outside the vehicle to cause secondary pollution to the environment, the vehicle-mounted butt-joint conveying device can effectively finish unloading for bulk material or material mixing vehicle-mounted equipment, particularly vehicle-mounted equipment such as a garbage compression vehicle or a garbage screening vehicle.
Alternatively, as shown in fig. 4, the multi-stage telescopic frame 10 includes a starting frame 11, a multi-stage intermediate frame 12 and an end frame 13, and the starting frame 11, the intermediate frame 12 and the end frame 13 are all hollow box-shaped. The multi-stage middle sleeve frame 12 is sequentially nested in a sliding manner from inside to outside. The starting sleeve frame 11 is fixed with the bottom plate in the carriage 130, and the outermost intermediate sleeve frame 12 is nested in the starting sleeve frame 11 in a sliding mode. The end stock 13 is slidably nested within the innermost intermediate stock 12, and the driven roller assembly 30 is connected to the end stock 13. In actual design, when the multi-stage telescopic frame 10 extends to the limit position, the overlap ratio between the sleeve frame and the sleeve frame is kept about 10% -20%, so that the multi-stage telescopic frame 10 has certain rigidity; when the multi-stage telescopic frame 10 retracts to the limit position, the overlap ratio between the frame and the frame is kept about 70-80%, so that the external dimension in the length direction is reduced. The more the number of the intermediate sleeves 12 of the multi-stage telescopic frame 10 is, the larger the telescopic stroke is, generally speaking, the telescopic amount can reach at least 1 meter, so as to meet the requirements of the butt joint and unloading operation.
In this alternative, as shown in fig. 4, 5 and 7, the starting jacket frame 11, the middle jacket frame 12 and the end jacket frame 13 each include an upper box plate 141 and a lower box plate 142 which are arranged opposite to each other in the up-down direction, and two side plates 143 which connect the upper box plate 141 and the lower box plate 142, and the upper box plate 141, the lower box plate 142 and the side plates 143 are enclosed to form a hollow cylinder. The side plate 143 is provided with a limit groove 1431 extending along the material conveying direction and penetrating through the plate body of the side plate 143. The side plates 143 of the middle sleeve frame 12 and the end sleeve frame 13 are further provided with a limiting block 144, and the limiting block 144 is positioned on one side of the limiting groove 1431 close to the starting sleeve frame 11. The limiting block 144 on the middle sleeve frame 12 is used for sliding matching with a limiting groove 1431 correspondingly arranged on the starting sleeve frame 11 or the upper middle sleeve frame 12 so as to respectively limit the extending limit position and the retracting limit position of the middle sleeve frame 12. The limiting block 144 of the end socket frame 13 is used for sliding fit with a corresponding limiting groove 1431 of the innermost middle socket frame 12, so as to respectively limit the extending limit position and the retracting limit position of the end socket frame 13.
Further, as shown in fig. 5 and 6, in order to reduce the wear of each stage of jacket frame during the expansion and contraction process, in an alternative of the present invention, the outer wall surfaces of the upper box plate 141, the lower box plate 142 and the side plates 143 of the middle jacket frame 12 and the end jacket frame 13 are respectively provided with a sliding block 145, and the sliding block 145 is disposed near one side of the starting jacket frame 11. The outermost intermediate holder 12 is slidably fitted in the starting holder 11 by the contact between the slider 145 and the inner wall surface of the starting holder 11. The intermediate holder 12 of the next stage is slidably fitted in the intermediate holder 12 of the previous stage by the contact between the inner wall surfaces of the intermediate holder 12 of the previous stage and the slider 145 of the intermediate holder 12 of the next stage.
