when the base 1 is moved, the coal seam in the advancing direction of the base 1 is not completely cut by a coal mining machine, a part of the coal seam is left, the output end of the double-shaft motor 801 drives the clamping sheet 209 and the conveyor belt 202 to rotate, the clamping sheet 209 is clamped with the driven gear 902, so that the driven gear 902 is driven to rotate, the driven gear 902 is driven to rotate by the transmission rod 901, the driven gear 903 drives the belt 904 to rotate, the belt 904 drives the driving teeth 211 to rotate, the driving teeth 211 drives the crushing cylinder 201 to rotate, a plurality of groups of crushing thimbles 208 arranged on the outer wall of the crushing cylinder 201 crush the remaining coal seam, and crushed coal blocks reach the scraper 3 under the driving of the crawler belt 402, so that the situation that the remaining coal blocks block the base 1 from advancing can be effectively avoided;
after the coal seam is cut, the coal seam at the back needs to be cut, at this time, the external mobile equipment pushes the base 1 to move towards the coal seam, the base 1 moves through the roller 404, the movable rod 401 and the supporting leg 403 move forwards simultaneously, if the advanced position is slightly depressed, the movable rod 401 slides downward by gravity, thereby driving the resistor 411 to slide downwards, increasing the length of the resistor 411 between the electrical contact 406 and the thread 407, thereby reducing the voltage divided among the groups of electromagnets 409, reducing the magnetic force of the electromagnets 409, ensuring that the thrust of the supporting spring 408 is larger than the pull force of the electromagnets, ensuring that the supporting legs 403 have the tendency of moving downwards, when the supporting leg 403 also enters the recess, the supporting leg 403 moves downward under the urging of the supporting spring 408 to contact with the inner wall of the recess, so that the supporting leg 403 can be tightly attached to the ground when moving; when the base 1 encounters a slight bulge when moving, firstly, the movable rod 401 contacts with the bulge through the crawler 402, so that the bulge can jack up the crawler 402 and the movable rod 401, the movable rod 401 can drive the resistor 411 to move upwards, so as to drive the resistor 411 to slide upwards, the length of the resistor 411 between the electric connector 406 and the thread 407 is reduced, so that the voltage distributed between each group of electromagnets 409 is increased, the magnetic force of the electromagnets 409 is improved, the thrust of the supporting spring 408 is smaller than the electromagnetic tension, the supporting leg 403 is pulled upwards by the electromagnet 409 and extrudes the supporting spring 408, the thrust of the supporting spring 408 is continuously increased until the same as the electromagnetic tension, the supporting leg 403 stops moving, the supporting leg 403 moves upwards, so that the supporting leg can be tightly attached to the bulge, when the ground slightly deforms, the base 1 can always keep stable in moving, the stability of the base 1 is improved.
