[0027] By rotating bidirectional threaded rod 8, the distance between the two mounting plates 2 can be adjusted accordingly.

[0028] Please refer to Figure 3 and Figure 4 , the drive assembly includes a hydraulic cylinder 11 and two stabilizing rods 12. Hydraulic cylinder 11 is installed on moving plate 3. And the telescopic end of hydraulic cylinder 11 is fixedly connected to one side of mounting plate 2. Two stabilizing grooves are opened on one side of moving plate 3 where it is located.

[0029] Please refer to Figure 2 , telescopic rods 9 are fixedly connected to both the bottom wall and the bottom wall inside lifting groove 7. Control switches 10 are installed on the opposite sides of the two telescopic rods 9.

[0030] The hydraulic cylinder 11 is electrically connected to two control switches 10. The uppermost control switch 10 controls the contraction of the telescopic rod 9 on the hydraulic cylinder 11, that is, drives the moving plate 3 away from the mounting plate 2. The lowermost control switch 10 controls the extension of the telescopic rod 9 on the hydraulic cylinder 11, that is, drives the moving plate 3 closer to the mounting plate 2. Touch plates are provided on the opposite sides of the two control switches 10. When the safety abutting plate 5 contacts the touch plate, the control switch 10 will be activated to operate.

This application will not go into too much detail. The servo motor 13 is electrically connected to the power supply.

[0035] Please refer to Figure 3 and Figure 4 , the safety abutting plate 5 includes a main board 501, a protruding board 502 and a baffle 503. The baffle 503 and the protruding board 502 are respectively fixedly connected to one side of the main board 501 and the upper part of the main board 501. An upper blocking board 15 and a lower blocking board 16 are respectively fixedly connected to the top wall and the bottom wall of the installation opening 14. One side of the protruding board 502 abuts against one side of the upper blocking board 15, and the bottom of the protruding board 502 contacts the upper part of the lower blocking board 16.

[0036] Working principle: Place the material between the two lifting plates 6, and the material abuts against the upper parts of the two lifting plates 6. Then use the lifting driving mechanism to lift the lifting plate 6 to slide in the lifting groove 7 and make the bottom of the material flush with the upper part of the conveyor belt. After that, use the rotation driving mechanism to drive the pushing wheels to drive the material to be conveyed onto the conveyor belt;

[0037] When the lifting plate 6 rises to be located at the corresponding mounting opening 14, the movable end of the safety abutting plate 5 will rotate upward. At the same time, the safety abutting plate 5 will completely rotate into the mounting opening 14 for storage, and the spring is in a compressed state until the lifting plate 6 passes through the mounting opening 14. At this time, the safety abutting plate 5 pops out of the cavity of the mounting opening 14 through the spring and resets. When the lifting plate 6 moves downward, the lower part of the lifting plate 6 will be abutted by the upper part of the safety abutting plate 5, so as to ensure that the material will not fall suddenly;

[0038] When it is necessary to lower or reset the lifting plate 6, only need to drive the hydraulic cylinder 11 to drive the moving plate 3 away from the mounting plate 2. The moving plate 3 will drive the moving rod 4 to slide out of the mounting opening 14. At the same time, the moving rod 4 will also drive the safety abutting plate 5 to disengage from the lifting groove 7, so as to prevent the safety abutting plate 5 from hindering the descent of the lifting plate 6;

[0039] Among them, when the lifting plate 6 lifts the material to a certain height, it will stop rising. At this time, the material is transported, and then the lifting plate 6 continues to rise and contacts the uppermost control switch 10. The control switch 10 starts the hydraulic cylinder 11 to drive the moving plate 3 away from the mounting plate 2. Then, the lifting plate 6 is driven to descend. When the lifting plate 6 is reset, the lifting plate 6 will contact the lowermost control switch 10, so as to use this control switch 10 to start the hydraulic cylinder 11 to drive the moving plate 3 to approach the mounting plate 2, so as to reset the safety abutting plate 5.
