[0025] The fixed base 1, the screening frame 2 and the feeding mechanism 4 are independent of each other and are respectively fixedly installed on the machine tool bracket.

[0026] The feeding mechanism 4 includes a raw material box 41 fixedly mounted on a machine tool support, a feeding frame 42 is fixedly connected to the bottom of the raw material box 41 , and a feeding cavity 43 is provided in the middle of the feeding frame 42 .

The upper and lower ends of the feeding chamber 43 pass through the feeding frame 42, and the upper end of the feeding chamber 43 is connected with the inside of the raw material box 41, and the lower end of the feeding chamber 43 is located directly above the feeding end of the screening frame 2.

[0028] The connector 9 includes a connecting block 91 fixedly connected to the feeding end of the multi-stage screening plate 11, the connecting block 91 corresponds to the multi-stage screening plate 11 one by one, a linkage spring 92 is fixedly connected between adjacent connecting blocks 91, a positioning spring 93 is connected to the side of the connecting block 91, and the other end of the positioning spring 93 is fixedly connected to the inner wall of the screening frame 2;

[0029] Due to the setting of the positioning spring 93, one end of the multi-stage screening plate 11 can vibrate up and down, and with the cooperation of the linkage spring 92, the vibration roller 95 and the vibrating screen plate 94 can drive the upper multi-stage screening plate 11 to vibrate, and at the same time, can drive multiple multi-stage screening plates 11 below to vibrate at the same time, and the vibration intensity can be adapted to the amount of raw materials on each top.

[0030] Among them, a vibration screen plate 94 is fixedly connected to the side of the outer surface of the top connection block 91 away from the positioning spring 93, and the vibration screen plate 94 is closely attached to the bottom of the multi-stage screening plate 11;

[0031] A vibration roller 95 is provided at the bottom of the vibration screen plate 94 . The cross section of the vibration roller 95 is elliptical. The outer surface of the vibration roller 95 contacts the bottom of the vibration screen plate 94 . A transmission rod 96 is fixedly sleeved inside the vibration roller 95 .

The bottom of the support rod 13 passes through the screening frame 2 and is fixedly connected to the fixed base 1. The support rod 13 is movably sleeved inside the screening frame 2.

[0034] The working principle and use process of this utility model:

[0035] Turn on the vibration motor 10 to drive the transmission rod 96 to rotate, which can drive the vibration roller 95 and the driving gear 6 to rotate synchronously. Due to the rotation of the vibration roller 95, its long and short axes are in continuous and alternating contact with the bottom of the vibrating screen plate 94, and then the left end of the multi-stage screening plate 11 is continuously vibrated up and down under the cooperation of the positioning spring 93 and the linkage spring 92;

[0036] The rotation of the driving gear 6 can drive the driven gear 7 to rotate through the transmission gear 8. Since the rotation of the driven gear 7 can drive the feeding roller 5 to rotate continuously, when the feeding roller 5 rotates, the raw materials dropped from the raw material box 41 and the feeding rack 42 can be transferred to the bottom of the inner cavity of the feeding cavity 43 through the feeding roller 5, and fall onto the receiving plate 12 under the action of gravity, and finally slide onto the multi-stage screening plate 11;

[0037] When there are a lot of falling materials in the fixed base 1, the fixed base 1 is pressed down due to the action of gravity and the support spring 3 is compressed, so that the transmission gear 8 on the front side of the fixed base 1 is disengaged from the driven gear 7 on the front side of the feeding roller 5. At this time, the driving gear 6 follows the continuous rotation of the vibration roller 95 and the transmission rod 96 and will not drive the feeding roller 5 to rotate, thereby stopping the transfer of raw materials; and after the screened raw materials in the fixed base 1 are discharged to reduce the overall weight of the fixed base 1, the driven gear 7 and the transmission gear 8 can be meshed again under the recovery action of the support spring 3, so as to continue feeding.
