[0038] When the present invention is in use, the coal mining cutter head 2 cuts and mines the coal seam, and at the same time the coal conveying device is started to convey the coal mine, that is, the conveying chain belt 5 starts to transmit and transport the coal mine. During this process, the plurality of toothed protrusions 7 on the upper layer of the conveying chain belt 5 continuously move in the direction away from the coal mining cutter head 2, and the plurality of toothed protrusions 7 on both sides of the upper layer of the conveying chain belt 5 can push against and push the plurality of first protrusions 9, thereby driving the two first transmission belts 8 to transmit.

[0039] At the same time, as the conveyor chain 5 continues to run, the several toothed protrusions 7 on the lower layer of the conveyor chain 5 push against the several second protrusions 13, thereby driving the second transmission belt 12 to transmit and run. Since the running direction of the several toothed protrusions 7 on the lower layer of the conveyor chain 5 is toward the coal mining cutter head 2, the second transmission belt 12 can drive the several pushing rods 14 close to the conveyor chain 5 to move toward the coal mining cutter head 2. At this time, the material to be transported can be placed on the inner circle of the second transmission belt 12 and pushed and moved by the pushing rods 14, thereby realizing the transportation of the material in the direction of the lower coal mining cutter head 2, effectively improving the efficiency of material handling.

[0040] Through the above operation, the material can be transported through the second transmission belt 12 to realize the transportation of anchoring and anchoring nets, and the anchoring nets are transported in a rolled-up state. When the material is transported to the notch position of the conveyor belt frame 6, the staff can take the material off and then carry out subsequent operations. The anchor rod supplement operation is carried out, that is, the anchor rods of the anchor rod drilling machine 17 are supplemented, so that several anchor rod drilling machines 17 can work normally. The anchor net can be unfolded, and then the unfolded anchor net can be cut into a suitable size, and the anchor net of suitable size can be placed on the side of the sliding plate 15, and several insertion rods 16 are used to insert and position it, and then the steel cable of the sliding plate 15 is started to drive the sliding plate 15 and the anchor net to rise, and finally move to the top of the support frame 4, and then as the sliding plate 15 moves, the sliding plate 15 is finally horizontal, and the anchor net is horizontally set to the top of the support frame 4, at this time, several anchor rod drilling rigs 17 located above the equipment body 1 can be started, the anchor net can be attached to the top of the tunnel and anchored, and then the anchor net fixing operation on the left and right sides of the equipment body 1 can be carried out. Through the above operation, the intensity of manual operation is effectively reduced, thereby improving work efficiency.
