Technical Field

[0001] The utility model relates to the technical field of dump trucks, in particular to a dump truck. Background Art

[0002] A dump truck is a means of transport used for transporting and loading and unloading materials. It is characterized by a reversible bucket that can be manually dumped. It is suitable for small-scale handling work, such as handling bulk materials in warehouses, factories and other places. The advantages of a dump truck are that it is flexible and lightweight, easy to operate, fast loading and unloading speed and high efficiency, and can quickly complete the transportation and loading and unloading of large amounts of materials; the disadvantage is that it needs to burn diesel or be charged. As a new type of transportation tool, the dump truck has a wide range of applications, is flexible and lightweight, and has the advantages of high efficiency and labor saving, making it an indispensable transportation equipment in many industries.

[0003] The working process of a dump truck is relatively simple, mainly including three steps: loading, transporting and unloading. Before loading, the operator parks the truck at the location where the goods are piled, and then the loader and unloader load the goods into the truck bucket; after loading, the operator controls the truck to move to the unloading location through the drive system, and when it is safely parked, the operator controls the truck bucket to unload the goods and complete the work. However, during the operation of the existing dump truck, the bucket cannot be flipped to a vertical state or a state close to a vertical state. When the bucket is loaded with small granular materials such as sand and soil, the flip angle of the bucket is not large enough to dump all the materials out. It is necessary to manually clean up and pour out the unpoured materials, which is time-consuming and labor-intensive, and has low transportation efficiency.

[0004] Therefore, how to design a dump truck that can dump all the materials in the transport vehicle without manual cleaning and dumping, thereby improving the transportation efficiency, is a technical problem that has not yet been solved in the prior art. Utility Model Content

[0059] When the dump truck of this embodiment is used, in the initial state, the bucket fixing structure controls the bucket 200 horizontally on the bucket mounting seat 6 through the bucket stopper 201; the two ends of the second rotating shaft 5 pass through the sleeve shaft 2 and pass through the first through hole 202, and the sleeve shaft 2 is movably installed in the first mounting groove 61; the first rotating shaft 3 is rotatably installed in the second mounting groove 62, and the bucket 200 does not contact the connecting plate 1. When the bucket 200 needs to be turned over, the bucket fixing structure is operated to release the control of the bucket 200, and the bucket 200 can turn forward and downward around the second rotating shaft 5 under the action of its own gravity, and the bucket 200 stops turning when it turns to the bottom and contacts the connecting plate 1; when the bucket 200 needs to be turned over again, the bucket 200 is pushed by external force to rotate around the first rotating shaft 3 until the stopper shaft 4 rotates to the third mounting groove 63, completing the second turning.

[0060] That is to say, in the dump truck of this embodiment, the bucket 200 can be flipped twice, so that the flipping angle of the bucket 200 can be close to a vertical state, and all the goods can be dumped out without manual cleaning and dumping, thereby improving transportation efficiency.

[0061] like Figure 4 and 8 As shown, the second mounting groove 62 has threaded through holes 64 on opposite sides thereof; it also includes a shaft stopper 7, the middle of which has an inverted U-shaped groove 71, and the two sides of the inverted U-shaped groove 71 have third through holes 72 on opposite sides thereof; after the first rotating shaft 3 is installed in the second mounting groove 62, the shaft stopper 7 is sleeved onto the first rotating shaft 3 through the inverted U-shaped groove 71, and the third through hole 72 is opposite to the threaded through hole 64; a bolt passes through the third through hole 72 and is threadedly connected to the threaded through hole 64. The shaft stopper 7 can limit the first rotating shaft 3 in the second mounting groove 62, so as to prevent the first rotating shaft 3 from losing its position when the bucket 200 rotates around the first rotating shaft 3, causing the bucket 200 to flip over too much and fall off the frame 100, thus causing a transportation accident.

When the truck bucket 200 needs to be flipped, the truck bucket hook 203 is pulled by the control handle 204 to release the connection between the truck bucket hook 203 and the truck bucket limiting member 201, thereby flipping the truck bucket 200.

[0064] like Figure 5As shown, a bucket base 205 is fixedly provided at the bottom of the bucket 200 , and rotating connecting plates 206 are provided on both sides of the bucket base 205 , and the first through hole 202 is opened on the rotating connecting plates 206 .

[0065] like Fig. 9 As shown, the vehicle frame 100 includes an armrest portion 101 and a mounting portion 102; and further includes a shock absorbing member 103, which is fixedly mounted between the armrest portion 101 and the mounting portion 102 and is used to reduce vibration for the transport vehicle. During the transportation of the transport vehicle, the shock absorbing member 103 can reduce vibration for the transport vehicle, making the transportation more stable.

[0066] The tilting device is mounted on the vehicle frame 100, the vehicle bucket 200 is mounted on the tilting device, and the fuel tank 300 and the engine 400 are mounted between the armrests 101. Two driving wheels 500 are mounted on both sides of the mounting portion 102.

[0067] The dump truck in this embodiment is used as follows: when using the dump truck in this embodiment, in the initial state, the truck bucket hook 203 and the truck bucket limiter 201 are engaged to horizontally control the truck bucket 200 on the truck bucket mounting seat 6; both ends of the second rotating shaft 5 pass through the sleeve shaft 2 and pass through the first through hole 202, and the sleeve shaft 2 is movably installed in the first mounting groove 61; the first rotating shaft 3 is rotatably installed in the second mounting groove 62, and the truck bucket 200 is not in contact with the connecting plate 1. When it is necessary to flip the bucket 200, pull the control handle 204, and pull the bucket hook 203 through the control handle 204 to release the control of the bucket limiter 201. The bucket 200 can flip forward and downward around the second rotation axis 5 under the action of its own gravity, and stop flipping when the bucket 200 flips to the bottom and abuts against the connecting plate 1; when the bucket 200 needs to be flipped again, push the bucket 200 through external force to make it rotate around the first rotation axis 3 until the limit axis 4 rotates into the third mounting groove 63, completing the second flipping.

[0068] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of this innovative technical solution.
