The extension assembly 44 is fixed to the support frame 15 connected with the transfer belt 41, and the extension assembly 44 includes a power output end. The power output end is connected with one end of the transfer belt 41 and drives the one end of the transfer belt 41 to extend to the outside of the side edge of the vehicle frame 12. The fourth position is located outside the vehicle frame 12.

[0040] With reference to Figure 1 and Figure 2 The dredging adjustment assembly 31 is fixed to the front end of the vehicle frame 12 and is separately arranged on the two sides of the front end of the vehicle frame 12 from the lifting assembly 21. One end of the dredging adjustment assembly 31 is fixed to the vehicle frame 12, and the other end forms a power output end. The cleaning assembly 32 is fixedly connected with the power output end of the dredging adjustment assembly 31, and the cleaning assembly 32 can be driven by the dredging adjustment assembly 31 to move from the second position to the first position.

[0041] In the embodiment, the coal powder particles below the belt are collected by the dredging mechanism 3 on the feeding mechanism 2, lifted and transferred to the transfer mechanism 4 above the vehicle frame 12 by the feeding mechanism 2, and further transferred to the fourth position away from the belt conveyor by the transfer mechanism 4 for treatment. The walking mechanism 1 can transfer the above-mentioned components to different positions of the belt conveyor, so as to comprehensively clean the below of the belt conveyor.

[0042] In the example embodiment of the present disclosure, with reference to Figure 1 and Figure 2The feeding mechanism 2 comprises two feeding rollers 23 rotatably connected to the second position and the third position respectively, the lifting assembly 21 comprises a transition roller 211 rotatably connected between the two feeding rollers 23, and a lifter 212 for moving one feeding roller 23 from the second position to the first position, and the transition roller 211 is always tensioned on the feeding belt 22.

[0044] In this embodiment, referring to Figure 2 The lifter 212 comprises a low-speed torque motor fixedly connected to the head of the frame 12 and a rotating rod fixedly connected to the power output end of the low-speed torque motor, one end of the rotating rod is fixedly connected to the low-speed torque motor, and the other end is rotatably connected to one feeding roller 23, and the rotation axis of the feeding roller 23 is parallel to the rotation axis of the power output end of the low-speed torque motor.

[0045] When it is needed to move one end of the feeding belt 22 from the second position to the first position through the lifting assembly 21 to move the material at the first position to the third position through the feeding belt 22, the rotating rod is driven to rotate by the low-speed torque motor, thereby driving the feeding roller 23 located at the second position to rotate around the output shaft of the low-speed torque motor at a low speed and to descend in height during the rotation, and to move from the second position to the first position. During the movement of the feeding roller 23, since the transition roller 211 is always in contact with the feeding belt 22, the feeding belt 22 will be displaced relative to the feeding roller 23 and the transition roller 211, and the feeding belt 22 is still tensioned after the feeding roller 23 moves from the second position to the first position.

[0048] In the embodiment, when the material needs to be transferred from the third position to the fourth position through the transfer mechanism 4, the power output end of the transfer telescopic device 441 drives one transfer roller 42 to move towards the fourth position, and the power output end of the tensioner 442 drives the tension roller 443 to move vertically upwards, so that the end of the transfer belt 41 towards the fourth position can approach the fourth position together with the transfer roller 42, and extend to the fourth position, thereby transferring the material from the third position to the fourth position. Due to the non-fixity of the fourth position, in actual operation, the stroke of the extension assembly 44 and the tensioner 442 can be adjusted according to the distance between the fourth position and the vehicle frame 12, thereby meeting the transfer of the material in different situations, and the transfer telescopic device 441 can be retracted to the minimum stroke, and the tensioner 442 can be extended to the maximum stroke, so as to reduce the length of the transfer belt 41 extending out of the vehicle frame 12, thereby meeting the purpose of the vehicle frame 12 moving in the narrow roadway.
