[0025] like Figure 4 , Figure 5As shown, the conveying mechanism includes a driving shaft 13 and a rotating shaft 14. The first end of the driving shaft 13 is fixedly connected to the output end of the conveying motor 6, and the second end of the driving shaft 13 passes through two side baffles 15 and is fixedly connected to a bearing 20. There are multiple bearings 20. The position of the driving shaft 13 close to the direction of the conveying motor 6 is fixedly connected to the bearing 20. Both ends of the rotating shaft 14 are fixedly installed in the bearing 20. A pair of conveying pulleys 16 are fixedly installed at the positions of the driving shaft 13 and the rotating shaft 14 close to the inner side walls of the side baffles 15. A conveying roller 17 is fixedly connected to the middle of the driving shaft 13 and the rotating shaft 14. A plurality of conveying rollers 18 are rotatably installed between the two side baffles 15. The conveying pulleys 16 on the driving shaft 13 and the rotating shaft 14 are connected through a conveyor belt 19.

[0026] like Figure 5 As shown, the auxiliary shock absorbing mechanism includes a bearing slide 21, in which a bearing 20 is fixedly installed. The upper and lower ends of the bearing slide 21 are fixedly connected to the first end of the shaft end spring 22, and the second end of the shaft end spring 22 is fixedly connected to the two ends of the rectangular groove of the side wall of the side baffle 15.

[0028] Working principle: When the device starts working, the control console 27 controls the conveying motor 6 to start, the conveying motor 6 drives the driving shaft 13 to rotate, and then drives the conveying belt wheel 16 to rotate, and the conveying belt wheel 16 drives the conveying belt 19 to rotate, so as to convey the material, and the conveying roller 18 is used to support and convey the material;

[0029] After the conveying motor 6 is started, the high-speed rotation of the driving shaft 13 causes the conveying motor 6 to vibrate, thereby compressing the damping plate 7, and the damping plate 7 moves downward, compressing the U-shaped support plate 8 to move downward. When the U-shaped support plate 8 moves downward, it drives the spring support block 9 to move downward, so that the bottom spring 10 is compressed, and the longitudinal shock absorption of the conveying motor 6 is achieved during the compression and reset of the bottom spring 10; when the conveying motor 6 vibrates, it drives the motor fixing plate 5 to vibrate together, and then drives the motor fixing seat 4 to move horizontally in the motor support seat 3. During the movement of the motor fixing seat 4, the side springs 11 and the rear springs 12 are compressed, and the lateral shock absorption of the conveying motor 6 is achieved during the compression and reset of the side springs 11 and the rear springs 12;

[0030] When the conveying motor 6 vibrates, the drive shaft 13 will also vibrate slightly. Since both ends of the drive shaft 13 are fixedly connected to the bearings 20, the drive shaft 13 drives the bearings 20 to move when vibrating, and the bearings 20 drive the bearing slide 21 to slide on the side wall of the side baffle 15, so that the shaft end spring 22 is compressed and reset, realizing auxiliary shock absorption of the drive shaft 13;

[0031] During the transportation of the device, the motor part and the transportation part will vibrate as a whole, thereby causing the upper support plate 2 supporting the upper working part to vibrate. After the upper support plate 2 vibrates, it compresses the hydraulic rod 24 to move downward, thereby compressing the main spring 25. At the same time, the upper support plate 2 will compress the spring sheet 26, causing the spring sheet 26 to be pressed down, and the elastic force of the main spring 25 and the spring sheet 26 is used to reset the upper support plate 2. At the same time, the presence of the hydraulic cylinder 23 and the hydraulic rod 24 can prevent the main spring 25 from rebounding quickly and affecting the shock absorption effect.
