[0002] Coal is a very precious natural resource. It is a solid combustible mineral that was gradually formed by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. The discovery, mining and processing of coal have provided convenience for human life. Due to the uneven road surface at the coal construction site and the inconvenience of short-distance transportation, most of the dump trucks on the market only rely on the wheels for shock absorption when encountering potholes during transportation, which cannot play a shock absorption role and easily lead to leakage of the transported coal, resulting in waste. Moreover, during the dumping process, the operator must stop and manually pull the lock to open it. After the operation is completed, the lock must be manually closed, which is cumbersome and inconvenient to use.

[0003] Therefore, it is urgent to improve the dump truck to solve the above-mentioned problems. Utility Model Content

One side of the lower end surface of the bucket 2 is hinged to the upper end surface of the bottom plate 101;

[0028] Further, such as Figure 2As shown, both sides of the support frame 1 are provided with connectors 7 for connecting with the bucket 2, and the connector 7 includes a circular slot 701 welded on the outside of the bottom plate 101 and a connecting rod 702 welded on the outside of the bucket 2 and rotatably connected with the circular slot 701, which facilitates the dumping of the bucket 2;

[0029] Furthermore, Figure 2 As shown, a support leg 8 is provided on the side of the lower end surface of the bottom plate 101 away from the connector 7, and the support leg 8 can effectively ensure the stability of the dump truck when it is parked;

[0030] Furthermore, if Figure 3 As shown, a compression spring 106 is sleeved on the telescopic column 102, and the cushioning property of the compression spring 106 is utilized to make the overall shock absorption effect better;

[0031] The fixing device 3 includes a fixing plate 301 arranged on the upper end surface of the bottom plate 101, a first fixing block 302 slidably connected to the fixing plate 301, a support plate 303 arranged on the side of the bucket 2 close to the fixing plate 301, a second fixing block 304 arranged on the lower end surface of the supporting plate 303, and second connecting columns 305 arranged on both sides of the upper end surface of the bottom plate 101, a pulley 306 is arranged on the upper end of the second connecting column 305, the first fixing block 302 and the pulley 306 are connected by a rope 10, and a handle 7 connected to the pulley 306 is arranged on the outer side of the upper end surface of the second connecting column 305; Figure 2 As shown, the handle 9 passes through the second connecting column 305 and is connected to the pulley 306. The side of the pulley 306 away from the handle 9 is rotatably connected to the second connecting column 305, which facilitates the operator to push and open the lock;

[0032] Further, such as Figure 6 As shown, both sides of the upper end surface of the fixed plate 301 are provided with sliding grooves 4, both sides of the sliding grooves 4 are provided with auxiliary sliding grooves 401, the lower end surface of the first fixed block 302 is slidably connected with the sliding grooves 4, both sides of the first fixed block 302 are provided with sliders 5 slidably connected with the auxiliary sliding grooves 401, the side of the sliding groove 4 close to the second connecting column 305 and the side of the slider 5 close to the second connecting column 305 are supported and connected by springs 6, and by utilizing the rebound effect of the spring 6, when the handle 9 is turned, the first fixed block 302 drives the slider 5 to slide outward in the auxiliary sliding groove 401, and when the handle 9 is released, the first fixed block 302 can be automatically reset;

[0033] Furthermore, Figure 3As shown, the first fixing block 302 is matched with the second fixing block 304. The first fixing block 302 is an arrow structure with an arrow pointing upward, and the second fixing block 304 is an arrow structure with an arrow pointing downward.

[0034] Furthermore, if Figure 1 As shown, a push rod 11 is provided on the side of the support plate 303 away from the bucket 2 to facilitate pushing the bucket 2 back to its original position;

[0035] Furthermore, Figure 3 As shown, a through groove 12 is vertically opened in the second connecting column 305, one side of the rope 10 is fixedly connected to the first fixed block 302, and the other side of the rope 10 passes through the lower end of the through groove 12 and is fixedly connected to the pulley 306 above. By utilizing the connection between the rope 10 and the pulley 306, the pulley 306 can drive the first fixed block 302 connected by the rope 10 to be pulled outward.

[0036] like Figure 1-Figure 8 As shown, the principle of the dump truck provided in this embodiment is as follows: when in use, add filler into the bucket 2, and after filling, push the handle 9 and use the wheel 105 to move. During the movement, the buffering effect of the telescopic column 102 and the compression spring 106 in the support frame 1 can effectively reduce shock and reduce coal leakage. After reaching the specified position, the handle 9 is rotated inward or outward on both sides to drive the pulley 306 to rotate, and the rope 10 is used to pull the first fixed block 302 to move to both sides, driving the slider 5 to slide in the sliding groove 4, squeezing the spring 6 to make the first fixed block 302 disengage from the second fixed block 304, so that the bucket 2 is tipped, and the handle 9 is released. Using the rebound effect of the spring 6, the first fixed block 302 automatically returns to its position. After pouring out the transported coal, the bucket 2 is returned to its original position, and the first fixed block 302 and the second fixed block 304 are automatically engaged.

[0037] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".
