[0024] The feeding mechanism 4 can make the nuts fall evenly into the crushing bin 2. Figure 1-2 As shown, the feeding mechanism 4 includes a flip frame 401 whose middle part is rotatably arranged on the frame 1 through a rotating shaft, a mounting plate 402 is fixed at the end of the flip frame 401, a pair of limit shafts 403 are fixed on the mounting plate 402, a connecting plate 404 is fixed at the corresponding position on the frame 1, the end of the limit shaft 403 extends to the side of the connecting plate 404, the outer side of the limit shaft 403 is sleeved with a compression spring 405, the compression spring 405 is arranged between the mounting plate 402 and the connecting plate 404, a connecting plate 406 extending into the hopper 3 is provided on the flip frame 401 through a rotating shaft, a support plate 407 is fixed at the end of the connecting plate 406, and the other end portion of the support plate 407 extends to the outside of the hopper 3.

[0025] The turning frame 401 rotates, and the mounting plate 402 at one end of the turning frame 401 squeezes the compression spring 405, and can drive the support plate 407 to shake left and right in the hopper 3 through the connecting plate 406, so that the nuts on the support plate 407 can fall evenly from the gap between the support plate 407 and the inner wall of the hopper 3.

[0026] An extension plate 408 is slidably installed on the support plate 407. The gap between the support plate 407 and the side wall of the hopper 3 can be changed by changing the installation position of the extension plate 408 on the support plate 407, thereby changing the feeding rate of the nuts. A long hole is opened on the extension plate 408, and a threaded through hole threadedly connected to the bolt is opened on the support plate 407. After moving the extension plate 408, the extension plate 408 can be fixed to the support plate 407 by bolts.
