Technical Field

[0001] This utility model relates to the field of dump truck technology, specifically a rear tipping support for dump trucks. Background Technology

[0002] Dump trucks are vehicles that unload goods themselves using hydraulic or mechanical lifting; they are also known as tipper trucks. Because the loading compartment can automatically tilt at a certain angle for unloading, they greatly save unloading time and labor, shorten transportation cycles, improve production efficiency, and reduce transportation costs, making them a commonly used type of special-purpose transport vehicle.

[0003] Traditional dump trucks use hydraulic devices to tilt the hopper when loading and unloading goods, causing the material to pour out from inside the head. However, the hydraulic device is exposed to the outside for a long time during use, causing dust to adhere to its surface, which can obstruct the rotation of the hydraulic device and affect its normal use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rear tipping support for dump trucks, which solves the problem mentioned in the background art where hydraulic devices are exposed to the elements for extended periods during use, causing dust to adhere to their surfaces, thus hindering the rotation of the hydraulic devices and affecting their normal operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dump truck rear tipping support, comprising a dump truck body, an mounting base fixedly mounted on the upper surface of the dump truck body, a vertical plate fixedly mounted on the upper surface of the mounting base, a first rotating shaft movably mounted on the adjacent surface of the vertical plate, a sleeve fixedly mounted on the outer surface of the first rotating shaft, a supporting inclined rod fixedly mounted on the outer surface of the sleeve, a movable block fixedly mounted on the left end of the supporting inclined rod, a connecting rod fixedly mounted on the front and rear surfaces of the movable block, a limit block fixedly mounted at the end of the connecting rod, a hopper provided on the upper surface of the mounting base, a groove provided on the lower surface of the hopper, a limit groove provided on the front and rear inner walls of the groove, a limit plate fixedly mounted on the inner wall of the limit groove, and a servo motor fixedly mounted on the rear surface of the vertical plate.

[0006] Furthermore, the upper surface of the mounting base is provided with a groove, a telescopic rod is fixedly installed on the lower inner wall of the groove, a spring is fixedly installed on the upper surface of the telescopic rod, a second rotating shaft is movably installed on the inner wall of the groove, and a buffer plate is fixedly installed on the outer surface of the second rotating shaft.

[0007] Furthermore, the outer surface of the connecting rod is in contact with the surface of the limiting plate, the outer surface of the limiting block is movably connected to the inner wall of the limiting groove, and the outer surface of the movable block is movably connected to the inner wall of the sliding groove.

[0008] Furthermore, the output end of the servo motor is fixedly connected to the rear end of the first rotating shaft, the servo motor is electrically connected to the main body of the dump truck, and the size of the support diagonal rod is matched with that of the slide groove.

[0009] Furthermore, the upper end of the spring is fixedly connected to the lower surface of the buffer plate, the upper end of the telescopic rod is fixedly connected to the lower surface of the buffer plate, and the outer surface of the buffer plate is movably connected to the inner wall of the groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The rear tipping support of this dump truck uses a servo motor to drive the first rotating shaft to rotate, thereby moving the movable block and the support rod to support the hopper.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please refer to the following: Figures 1-5 This utility model provides a technical solution: a dump truck rear tipping support, including a dump truck body 1, an mounting base 2 fixedly mounted on the upper surface of the dump truck body 1, a vertical plate 3 fixedly mounted on the upper surface of the mounting base 2, a first rotating shaft 4 movably mounted on the adjacent surface of the vertical plate 3, a sleeve 5 fixedly mounted on the outer surface of the first rotating shaft 4, a supporting inclined rod 6 fixedly mounted on the outer surface of the sleeve 5, a movable block 7 fixedly mounted on the left end of the supporting inclined rod 6, a connecting rod 8 fixedly mounted on the front and rear surfaces of the movable block 7, a limit block 9 fixedly mounted at the end of the connecting rod 8, a hopper 10 provided on the upper surface of the mounting base 2, a sliding groove 11 provided on the lower surface of the hopper 10, and limit grooves 1 on the front and rear inner walls of the sliding groove 11. 2. A limiting plate 13 is fixedly installed on the inner wall of the limiting device, and a servo motor 14 is fixedly installed on the rear surface of the vertical plate 3. Specifically, the main body 1 of the dump truck controls the servo motor 14 to start, thereby driving the first rotating shaft 4 to rotate. The first rotating shaft 4 rotates, thereby driving the sleeve 5 and the support inclined rod 6 to rotate, thereby driving the movable block 7 to slide inside the slide groove 11. At this time, the limiting block 9 moves along the inside of the limiting groove 12. When the movable block 7 moves to the right, the hopper 10 is flipped, thereby dumping the goods inside. After dumping, the servo motor 14 reverses, thereby driving the movable block 7 to move to the left, thereby recovering the hopper 10, thus completing the unloading.

[0022] In this embodiment, a groove 15 is provided on the upper surface of the mounting base 2. A telescopic rod 16 is fixedly installed on the lower inner wall of the groove 15. A spring 17 is fixedly installed on the upper surface of the telescopic rod 16. A second rotating shaft 18 is movably installed on the inner wall of the groove 15. A buffer plate 19 is fixedly installed on the outer surface of the second rotating shaft 18. Specifically, when the hopper 10 is unloading and undergoing recycling, when the hopper 10 contacts the buffer plate 19, the design of the spring 17 and the telescopic rod 16 buffers the buffer plate 19. The buffer plate 19 directly transmits the buffering force to the lower part of the hopper 10, thereby buffering the hopper 10. The closer it is to the upper part of the mounting base 2, the greater the compression force of the spring 17, and the greater its buffering force, so that it slowly approaches the mounting base 2 until the buffer plate 19 enters the interior of the groove 15. At this time, the upper surface of the mounting base 2 and the lower surface of the hopper 10 are in contact with each other, thereby completing the recycling buffer.

[0023] In this embodiment, the outer surface of the connecting rod 8 is in contact with the surface of the limiting plate 13, the outer surface of the limiting block 9 is movably connected to the inner wall of the limiting groove 12, and the outer surface of the movable block 7 is movably connected to the inner wall of the slide groove 11. Specifically, through the design of the limiting block 9 and the limiting groove 12, the movable block 7 is limited inside the slide groove 11 to prevent it from shifting or falling off.

[0024] In this embodiment, the output end of the servo motor 14 is fixedly connected to the rear end of the first rotating shaft 4, the servo motor 14 is electrically connected to the dump truck body 1, and the size of the support rod 6 and the chute 11 are matched. Specifically, the servo motor 14 drives the first rotating shaft 4 to rotate, thereby driving the support rod 6 to move, thus supporting the hopper 10. When the hopper 10 is recovered, the support rod 6 will be completely inside the chute 11.

[0025] In this embodiment, the upper end of the spring 17 is fixedly connected to the lower surface of the buffer plate 19, the upper end of the telescopic rod 16 is fixedly connected to the lower surface of the buffer plate 19, and the outer surface of the buffer plate 19 is movably connected to the inner wall of the groove 15. Specifically, the telescopic rod 16 and the spring 17 form a damping spring 17, which buffers the hopper 10 when it contacts the buffer plate 19.

[0026] Working principle: When this utility model is in use, if it is necessary to dump the goods inside the hopper 10, the servo motor 14 is started by controlling the main body 1 of the dump truck, which drives the first rotating shaft 4 to rotate. The rotation of the first rotating shaft 4 drives the sleeve 5 and the supporting inclined rod 6 to rotate, thereby causing the movable block 7 to slide inside the slide groove 11. At this time, the limiting block 9 moves along the inside of the limiting groove 12. When the movable block 7 moves to the right, the hopper 10 is flipped, thereby dumping the goods inside. After dumping is completed, the servo motor 14 reverses, thereby driving the movable block 7 to move to the left, thereby recovering the hopper 10 and completing the unloading.

[0027] When the hopper 10 completes unloading and begins recycling, it comes into contact with the buffer plate 19. The design of the spring 17 and the telescopic rod 16 buffers the buffer plate 19, which transmits the buffering force directly to the bottom of the hopper 10. The closer the hopper 10 is to the top of the mounting base 2, the greater the compression force of the spring 17 and the greater the buffering force, causing it to slowly approach the mounting base 2 until the buffer plate 19 enters the interior of the groove 15. At this point, the upper surface of the mounting base 2 and the lower surface of the hopper 10 are in contact, thus completing the recycling buffer.

[0028] The selection of various devices differs depending on the specific circumstances, and should be based on actual needs, taking into account various parameters, and ensuring that the equipment's function and desired effect are aligned. 。

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. 。
