[0035] One side of the support block 83 fixedly connected to the claw body 7 is hingedly connected to one side of the second connecting rod 82, the other side of the support block 83 is hingedly connected to one end of the fifth support rod 75, the other end of the fifth support rod 75 is hingedly connected to one end of the sixth support rod 76, and the other end of the sixth support rod 76 is concentrically hinged at the hinge position of the third support rod 73 and the second connecting rod 82.

[0036] The operating principle of the utility model is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, before use, the first electric jacking cylinder 31 is placed horizontally, the second electric jacking cylinder 32 is placed vertically, and the output end of the second electric jacking cylinder 32 is at the lower end, and the claw body 7 is placed in a folded shape.

[0038] When in use, start the moving device to drive the base 1 close to the inner wall of the cargo hold. The moving device is preferably a tracked vehicle, which is convenient for moving on uneven ground. After the tracked vehicle moves into place, start the third electric top cylinder 24 first. The extended end of the third electric top cylinder 24 drives the hinged chassis 25 to rotate in a counterclockwise direction, and drives the first electric top cylinder 31 connected to the chassis 25 to flip and lift in a counterclockwise direction. Since the third electric top cylinder 24 is hingedly connected to the bracket 23, as the third electric top cylinder 24 is extended and the position of the chassis 25 rises and changes, the non-extended end of the third electric top cylinder 24 can also be adaptively rotated and adjusted to avoid movement interference.

[0039] After the first electric top cylinder 31 is rotated and lifted into position, the second electric top cylinder 32 is started, and the electric rotating cylinder 4 and the connected translation unit and lifting unit are synchronously moved close to the inner wall of the cargo hold. After the output end of the second electric top cylinder 32 is moved into position, the second power motor 61 is started again according to the specific position of the target coal block, so that the threaded connecting frame 53 moves in the vertical direction along the third screw rod 62, and synchronously drives the claw body 7 to move. Then, the first power motor 51 is started, so that the threaded connecting frame 53 moves in the horizontal direction along the second screw rod 52, and also synchronously drives the claw body 7 to move.

[0040] Then, the linear motor 80 is turned on, and the output end of the linear motor 80 moves back, driving the guide block 801 to move up along the vertical rod 802 and the first connecting rod 81 to rotate in the clockwise direction, and synchronously driving the first support rod 71, the second support rod 72, the third support rod 73 and the fourth support rod 74 which are hingedly connected to each other to rotate in the clockwise direction at the same time. Among them, since the third support rod 73 has three hinge positions, a third guide rod 70 passing through the guide groove 63 is provided at one end adjacent to the second fixed plate 6, and the third guide rod 70 slides in the axial direction of the guide groove 63, so that the third support rod 73 drives the second connecting rod 82 to move, and as the second connecting rod 82 moves up, the claw body 7 is synchronously driven to move up until it is arranged in a vertical shape (such as Figure 4 and Figure 6 status shown).

[0041] At this time, according to the distance between the claw body 7 and the coal block on the cabin wall, the driving motor 20 is started, and the fixed block 22 is translated on the fitted bottom plate 2 to approach the coal block. After it is adjusted to the right position, the linear motor 80 is started again, and the output end of the linear motor 80 moves outward, driving the guide block 801 to move down along the vertical rod 802 and the first connecting rod 81 to rotate in the counterclockwise direction, and synchronously drives the first support rod 71, the second support rod 72, the third support rod 73 and the fourth support rod 74 which are hingedly connected to each other to rotate in the counterclockwise direction at the same time, and the third support rod 73 drives the second connecting rod 82 to move down, and also synchronously drives the claw body 7 to move down until it is in a folded shape, and at the same time, the hinged ends of the fifth support rod 75 and the sixth support rod 76 rotate in the clockwise direction, and make the sixth support rod 76 coincide with one end of the second connecting rod 82 (such as Figure 3 and Figure 5 After reaching the folded position, the linear motor 80 is started in reverse, and the claw body 7 is unfolded according to the corresponding steps mentioned above, and the claw body 7 is moved back and forth in this way, that is, a claw-retracting and scraping action is completed to remove the coal blocks on the inner wall of the cargo hold.

[0042] During the reciprocating movement of the claw body 7, according to the coal planing situation, the first power motor 51 or the second power motor 61 should be started in time to drive the claw body 7 to move in the horizontal direction or the vertical direction respectively, so as to meet the requirements of continuous coal planing and improve the coal planing efficiency.

[0043] It should be noted that, if the coal blocks are not piled high, the first electric cylinder 24 only needs to be rotated to a certain angle to be used (such as Figure 7 in addition, due to the wide distribution of the positions of the residual coal blocks, some coal blocks in the corners may not be removed during the initial coal planing. Under necessary conditions, the electric rotary cylinder 4 can be started to drive the translation unit, the lifting unit, the extension assembly and the claw body 7 to rotate synchronously in the vertical direction to fit the residual positions of the coal blocks for planing operations.

[0044] In addition, in order to improve the use efficiency and ensure the use stability, combined with the width of the claw body 7, the first support rod 71, the second support rod 72, the third support rod 73, the fourth support rod 74, the fifth support rod 75 and the sixth support rod 76, as well as the first connecting rod 81, the second connecting rod 82 and the support block 83 are all arranged in a left-right symmetrical form (such as Figure 3 and Figure 4 status shown).

[0045] In addition, in order to ensure the normal use of the above-mentioned electronic components, a power supply (not marked) should be set on the base 1, and the power supply is preferably a battery; in order to facilitate operation, a camera (not marked) and a PLC controller (not marked) connected to each motor are set on the base 1, and then a remote control with a display function wirelessly connected to the camera and the PLC controller is set for remote operation to improve the accuracy of the coal planing operation.

[0046] This application does not involve the control principle of the PLC controller and is a direct use of the existing technology, so the specific connection settings of the PLC controller will not be repeated here.
