Through the casters 11 provided on the base plate 1, when the staff controls the movement of the device, the casters 11 provided on the bottom end of the device can facilitate the movement of the device, and then through the hydraulic cylinder 12 provided on the base plate 1 and the anti-skid plate 13 fixedly provided on its output end, the friction between the ground can be increased, thereby ensuring the stability and safety of the device when in use.

[0033] Reference Figure 1-3 A discharge port 31 is provided on the top plate 3, and a discharge pipe 32 is fixedly provided on the lower end surface of the top plate 3. The upper end of the discharge pipe 32 matches the discharge port 31. Through the discharge port 31 provided on the top plate 3, the device can discharge the material through the discharge port 31 on the top plate 3 after completing the processing of the material, and then transport the material to a predetermined position through the discharge pipe 32 to complete the collection.

[0034] Reference Figure 1-2 The discharge port 31 is funnel-shaped with a large upper end and a small bottom end, and the discharge pipe 32 is curved. By setting the discharge port 31 to be funnel-shaped with a large top end and a small bottom end, the material receiving area of ​​the discharge port 31 is increased.

[0035] Reference Figure 1 、 3And 4, the positioning mechanism 7 includes a loading plate 71 rotatably set on the top plate 3, a plurality of evenly arranged U-shaped frames 72 are fixedly set on the loading plate 71, an extrusion column 73 is slidably set on the U-shaped frame 72, and a positioning jig 74 corresponding to the extrusion column 73 is fixedly set on the other end of the extrusion column 73, an adjustment unit 75 for controlling the elongation of the extrusion column 73 is fixedly set on the top plate 3, and a controller for controlling the rotation of the loading plate 71 is fixedly set on the top plate 3. By means of the loading plate 71 set on the top plate 3 and the U-shaped frame 72 fixedly set on the loading plate 71, the positioning and installation of the material to be processed is realized, and the prepared material can be placed in the U-shaped frame 72, which is simple and convenient.

[0036] Reference Figure 1 、 3 And 4, the adjustment unit 75 includes a turntable 751 fixedly set on the output end of the motor 6, the turntable 751, and a guide plate 752 fixedly set in the loading plate 71, a plurality of arc grooves 753 of the same size are provided on the turntable 751, and a guide groove 754 is provided on the guide plate 752. A slide rod 755 is slidably provided on the guide groove 754 and the arc groove 753 to ensure that the slide rod 755 passes through the guide groove 754 and the arc groove 753. The turntable 751 provided on the motor 6 can realize that when the staff starts the motor 6, the turntable 751 fixedly connected to the output end of the motor 6 rotates. At this time, as the turntable 751 rotates, the slide rod 755 slidingly set on the arc groove 753 of the turntable 751 moves, and then the moving direction of the slide rod 755 is controlled by the guide groove 754 provided on the guide plate 752 to ensure the stability of the device when it is used.

By setting the horizontal height of the shaft 7552, it is ensured that the shaft 7552 can keep the material in the positioning mechanism 7 squeezed and fixed during the movement, so that the device can be processed stably.

[0039] The specific solution is as follows: when using the device, the staff first moves the device to a suitable position, and through the casters 11 set on the bottom plate 1, the staff can control the movement of the device. The casters 11 set on the bottom end of the device can facilitate the movement of the device. Then, the hydraulic cylinder 12 set on the bottom plate 1 and the anti-skid plate 13 fixed on its output end can increase the friction between the ground and ensure the stability and safety of the device when in use. The loading tray 71 set on the top plate 3 and the U-shaped frame 72 fixed on the loading tray 71 realize the positioning and installation of the material to be processed, and the prepared material is placed in the U-shaped frame 72 That is, when the staff starts the motor 6, the turntable 751 fixedly connected to the output end of the motor 6 rotates. At this time, as the turntable 751 rotates, the slide bar 755 set on the arc groove 753 of the turntable 751 moves, and then the moving direction of the slide bar 755 is controlled by the guide groove 754 set on the guide plate 752 to ensure the stability of the device during use. The slider 7551 set on the slide bar 755 is realized by the slider 7551 being always in contact with the inner wall of the guide groove 754 during the movement of the slide bar 755, thereby ensuring that the slide bar 755 moves in parallel without axial rotation, thereby completing the precise positioning of the material.
