the two side positions of the support frame 2 are symmetrically sleeved with the sleeve frames 7, the two sleeve frames 7 are connected through the support plate 4, and the sleeve frames 7 move on the support frame 2 due to the mobility of the sleeve frames 7, so that when the conveyor belt 3 drives the driving motor 1 to move, the sleeve frames 7 on the two sides are also driven to synchronously move, and the two sleeve frames 7 can better control the movement stability of the driving motor 1;

in the design, the bearing frame 6 and the sleeve frame 7 are connected and fixed, so that the supporting plate 4 can not drive the motor 1 forwards when the driving motor 1 and the jacking pipe work are stopped, when the bearing frame 6 can drive the sleeve frame 7 forwards because of the driving of the conveying belt 3, the supporting plate 4 does not move at the moment, the sleeve frame 7 moves forwards along a slideway on the supporting plate 4 and self-moves forwards, and a compression spring 803 in the outer frame 802 can be compressed by a round rod 801 in the moving process, so that buffering during stopping is achieved;

the buffer can solve the problem that the upper side pause is not matched with the lower side movement when the problem occurs, and meanwhile, the moving pressure can be properly slowed down when the buffer is performed due to the arrangement of the compression spring 803;
