The bucket 2 is provided with a coal shoveling member 9 and a driving unit that drives the coal shoveling member 9 to move along the interior of the bucket 2.

[0033] The coal shoveling part 9 includes a mounting plate 92 arranged inside the truck bed 2. The bottom of the mounting plate 92 is provided with a cleaning plate 93 and a cleaning part 97 distributed in sequence along its moving direction. The coal shoveling side of the cleaning plate 93 is beveled to form a cleaning part. The cleaning part 97 mainly includes a base plate. The bottom of the base plate is provided with dense brush strips, which clean the inside of the truck bed 2 through the brush strips.

[0034] Regarding the above-mentioned driving part, the driving part includes a movable plate 91 arranged inside the truck bed 2, and a cylinder 5 is also provided on the upper side of the truck bed 2. A slot is opened at the bottom of the movable plate 91, and the mounting plate 92 is installed in the slot. The cylinder 5 is connected to the pneumatic hydraulic system 4.

Then, the truck bed 2 can be opened to allow the coal to be tilted downward from the truck bed 2, thereby realizing the transportation of the coal.

[0036] After the bucket 2 is unloaded, the pneumatic-hydraulic system 4 can be used to control the extension and contraction of the piston rod inside the cylinder 5, so that the cylinder 5 drives the movable plate 91 to move through its piston rod. At this time, the movable plate 91 drives the cleaning plate 93 and the cleaning member 97 to move along the inside of the bucket 2. During the movement, the cleaning plate 93 can clean the inside of the bucket 2, and the cleaning member 97 can be used to brush the inside of the bucket 2, thereby cleaning the inside of the bucket 2, thereby avoiding coal residue in the bucket 2. There is no need for coal miners to manually clean the bucket 2, which can greatly reduce the labor intensity of coal miners and help improve the work efficiency of coal miners.

[0037] Among them, it should be noted that the crawler walking part 1 in this embodiment mainly includes a crawler chassis and a walking motor reducer, the pneumatic hydraulic system 4 includes a pneumatic device and a hydraulic system, the hydraulic system is electrically connected to the walking motor reducer, and the hydraulic system includes an oil tank assembly; the pneumatic device includes an air motor and an air source triplet, the air motor is connected to the air source triplet, the underground compressed air enters the air motor through the air source triplet, the air motor is connected to the hydraulic system, and the air motor drives the crawler walking part 1 to move through the hydraulic system, and the structures and principles of the crawler walking part 1 and the pneumatic hydraulic system 4 are all existing technologies. For details, please refer to the comparative document (publication number: CN109606097A, name: Mining crawler pneumatic material transport vehicle), which will not be elaborated here.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, a sliding block 10 is mounted on the top of the movable plate 91, a bracket 6 is mounted on the rear end of the bucket 2, and a crossbar 7 is installed between the bracket 6 and the head of the bucket 2. The sliding block 10 is slidably connected to the crossbar 7. Based on this, when the cylinder 5 drives the movable plate 91 to move along the inside of the bucket 2, the sliding block 10 can slide along the crossbar 7 to limit the movable plate 91, facilitating the stable movement of the movable plate 91 and facilitating the cleaning of the inside of the bucket 2.

[0039] Furthermore, in order to increase the stability of the moving plate 91 during its movement, as shown in FIG. Figures 1-4 As shown, limiting strips 8 are installed on both sides of the inner wall of the bucket 2, and limiting grooves matching with the limiting strips 8 are opened on both sides of the movable plate 91.

[0041] When the cleaning plate 93 and the cleaning member 97 need to be replaced, the stop block 944 can be pulled upward by the pull rod 941, so that the stop block 944 rises along the cavity and squeezes the spring 949 to shrink until the stop block 944 is separated from the insertion block 942. Then the mounting plate 92 is pulled to move the insertion block 942 from the opening, thereby removing the mounting plate 92 from the notch at the bottom of the movable plate 91, and then the cleaning plate 93 and the cleaning member 97 are replaced. After replacement, the mounting plate 92 can be inserted into the The movable plate 91 is inserted into the groove at the bottom thereof, and the insertion block 942 is driven to be inserted into the cavity from the opening. Then the pull rod 941 is loosened, and the spring 949 pushes the stop block 944 to descend along the cavity until it is plugged into one side of the insertion block 942, so as to plug and fix the insertion block 942, thereby realizing the installation and fixation of the mounting plate 92 and the movable plate 91, thereby realizing the rapid disassembly and assembly of the cleaning plate 93 and the cleaning part 97, facilitating the replacement of the cleaning plate 93 and the cleaning part 97, and being beneficial to ensuring the cleaning effect of the coal shoveling part 9 on the bucket 2.

[0044] Furthermore, in order to facilitate the fit of the blocking block 944 and the inserting block 942, the inserting block 942 is inserted and blocked, as shown in FIG. Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, one side of the insertion block 942 and the adjacent stop block 944 is beveled to form a fitting portion 947 , and one side of the two fitting portions 947 extends outward to form an extension portion 948 .
