a rejecting mechanism adapted to couple with the screen 120 in conjunction with the movement of the screen 120 for changing the aperture size of the screen 120 to reject stem jammed within the screen 120.

That is, the screen 120 is driven by the vibration motor to move up and down in the vibrating groove 111 of the frame 110, the tobacco stems are thrown onto the screen 120 from the upper end of the screen 120, and the tobacco stems on the screen 120 move along the extending direction of the screen 120 (from the high end 121 to the low end 122 of the screen 120) along with the up and down vibration of the screen 120, wherein the waste materials in the tobacco stems are sifted by the screen 120, and part of the original stems are blocked in the mesh 123, and at this time, the original stems blocked in the screen 120 are removed under the action of the removing mechanism; this former stalk screening machine 100 can avoid screen cloth 120 to take place to block up, improves work efficiency, improves the utilization ratio of offal.

In an example of the present invention, the removing mechanism includes:

a rejection plate 130 fixedly coupled within the seismic trough 111 and located at a lower end of the screen 120;
