Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary unloading, in particular to an auxiliary unloading mechanism for a dump truck to unload goods. Background Technique

[0002] A dump truck refers to a vehicle that unloads goods by hydraulic or mechanical lifting, also known as a tipping truck, which is composed of a vehicle chassis, a hydraulic lifting mechanism, a cargo box and other components. The cargo box of the dump truck is divided into two types: rearward tipping and side tipping. By controlling the movement of the piston rod through the control system, rearward tipping is more common, pushing the piston rod to tip the cargo box, and a few are double tipping.

[0003] At present, the unloading method of a dump truck mainly relies on the inclination of the vehicle body and the action of gravity, and it cannot move during the unloading process. Therefore, the goods unloaded on the ground are easy to pile up. For sandy or muddy goods, the pile-up will bury the tires of the vehicle. After the tires are buried, the vehicle may be hindered when starting or turning, resulting in poor driving. Based on this, this solution provides an auxiliary unloading mechanism for a dump truck to solve the above-mentioned problems. Content of the Utility Model

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0024] Refer to Figures 1 - 5As shown in the figure, an auxiliary unloading mechanism for a dump truck to unload goods includes a vehicle chassis 1. At the lower end of the vehicle chassis 1, two sets of wheels 2 are rotatably installed. At the right end of the vehicle chassis 1, a vehicle head 3 is provided. In the middle of the upper end of the vehicle chassis 1, a first rectangular groove 4 is opened. At the bottom end inside the first rectangular groove 4, an inclination sensor 5 is provided. The inclination sensor 5 can adopt the model: 3DM-GX3-25. The inclination sensor 5 can be any sensor that can achieve this function in the prior art without limitation. The inclination sensor 5 is electrically connected to the vehicle machine in the cab. The inclination sensor 5 can measure the inclination angle of the cargo box 10 in real time to ensure the stability of the vehicle body during the lifting and unloading process and prevent the dump truck from tipping over due to excessive inclination of the cargo box 10. When the detected inclination angle exceeds the safety threshold, an alarm will be issued on the vehicle machine in the cab to remind the operator to take corresponding measures. On the upper end of the vehicle chassis 1, a cargo box 10 is provided. At the rear end of the cargo box 10, a unloading auxiliary component 7 is provided. The unloading auxiliary component 7 includes a fixed frame 701. The front end of the fixed frame 701 abuts against the rear end of the vehicle chassis 1. The fixed frame 701 is installed at the rear end of the vehicle chassis 1 through a locking bolt 702. The fixed frame 701 can be detached from the vehicle through the locking bolt 702. After detachment, it is more convenient to inspect and clean the component, timely discover and solve wear or fault problems, and extend the service life of the equipment. On the front and rear sides of the rear end of the fixed frame 701, extension blocks 703 are fixedly connected. Between the two extension blocks 703, a rotating rod 704 is rotatably installed. On the surface of the rotating rod 704, a unloading plate 705 is provided. The unloading plate 705 can block the sediment-like goods and reduce their direct contact with the wheels 2, thereby preventing the tires from being buried in the sediment. After the sediment is effectively isolated, the goods can be unloaded more quickly without worrying about the wheels 2 slipping or getting stuck in the mud. On the front and rear sides of the upper end of the unloading plate 705, limit plates 706 are fixedly connected. Through holes 707 are opened through the front ends of the two limit plates 706.

[0025] Referring to Figures 3 - 5As shown in the figure, a baffle 13 is rotatably installed at the rear end of the cargo box 10. A limiting groove 6 adapted to the limiting hole 707 is formed through the front end of the baffle 13. A limiting rod 17 is arranged inside the limiting groove 6 and the limiting hole 707. Threads 18 are arranged at both ends of the outer surface of the limiting rod 17. The limiting rod 17 is fixed inside the limiting groove 6 and the limiting hole 707 through the cooperation of the threads 18 and the nuts 19. When transporting goods, it is necessary to rotate the unloading plate 705 to the rear side of the baffle 13. By inserting the limiting rod 17 into the limiting groove 6 and the limiting hole 707 and then using the nuts 19 to limit both ends of the limiting rod 17, the unloading plate 705 can be fixed at the rear end of the baffle 13. When unloading is required, the limiting rod 17 can be extracted from the limiting groove 6 and the limiting hole 707 to move the unloading plate 705. A second rectangular groove 8 is arranged at the front end of the first rectangular groove 4. The second rectangular groove 8 is formed at the upper end of the vehicle chassis 1. A lifting oil cylinder 9 is arranged inside the second rectangular groove 8. The output end of the lifting oil cylinder 9 is rotatably connected to a hinge seat arranged at the front side of the lower end of the cargo box 10. The rear side of the lower end of the cargo box 10 is rotatably installed with the upper rear side of the vehicle chassis 1 through a hinge seat. A hydraulic cylinder 11 is fixedly installed at the right end of the cargo box 10. The output end of the hydraulic cylinder 11 extends into the cargo box 10 and is fixedly connected to a push plate 12. The hydraulic cylinder 11 drives the push plate 12 to move on the inner side wall of the cargo box 10 to push the goods remaining in the cargo box 10 out of the cargo box 10, reducing residues and improving the unloading efficiency. A fixing block 14 is arranged at the rear end of the vehicle head 3. The lower end of the fixing block 14 is fixedly connected to the upper end of the vehicle chassis 1. A placement groove 15 is formed at the upper end of the fixing block 14. A rubber pad 16 is arranged at the bottom end inside the placement groove 15. When the cargo box 10 moves to the lowest end, the hydraulic cylinder 11 just moves above the rubber pad 16 arranged inside the placement groove 15.

[0026] Working principle and usage process of the utility model: Before unloading, by rotating the nuts 19 at both ends of the limit rod 17, after removing the nuts 19 from the limit rod 17, then pulling out the limit rod 17 from the inside of the limit groove 6 and the limit hole 707. At this time, the unloading plate 705 can move. Then, make the rear end of the unloading plate 705 contact the ground, so that the unloading plate 705 is in an inclined state. Then, drive one end of the cargo box 10 to move upward through the lifting oil cylinder 9, so that the cargo box 10 can be inclined with the upper rear side of the chassis as the origin. When inclined to a certain extent, the sediment-like goods inside the cargo box 10 slide out of the cargo box 10 from the rear end under the action of gravity. And during the upward movement of the cargo box 10, the inclination angle is collected in real time through the inclination sensor 5, and an alarm is issued when it exceeds the preset threshold to ensure safety. When the sediment-like goods in the cargo box 10 no longer slide from the inside of the cargo box 10 to the ground, there may be some sediment-like goods remaining inside the cargo box 10. At this time, drive the push plate 12 to move through the hydraulic cylinder 11, so that the push plate 12 moves along the inner side wall of the cargo box 10, scraping off the sediment-like goods that may remain on the inner wall of the cargo box 10. The scraped sediment-like goods slide to the ground along the unloading plate.
