[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. Pour the nuts from the inlet, and the nuts will fall from the inlet pipe onto the second filter plate and the lower crushing teeth. Then start the cylinder, which drives the expansion and contraction of the connecting block, which drives the expansion and contraction of the connecting plate, and the expansion and contraction of the connecting plate drives the upper crushing teeth to expand and contract in the direction of the lower crushing teeth. The mutual contact and extrusion of the upper crushing teeth and the lower crushing teeth are conducive to shelling the nuts on the second filter plate; while the upper crushing teeth are in contact and extrusion with the lower crushing teeth, the lower crushing teeth and the second filter plate are driven to slide on the slide groove, which in turn drives the slide to squeeze the fixed slide, thereby generating a pressure on the spring. Therefore, when the upper crushing teeth rise, the spring will give a rebound force to the fixed slide, and then give a rebound force to the slide, thereby giving a rebound force to the nuts on the second filter plate and the lower crushing teeth and causing them to vibrate, thereby accelerating the filtering process of shelling the nuts.

[0009] 2. The filtered fruit particles and nut shells will fall onto the first filter plate, and then the vibrator is turned on. The vibrator drives the vibration of the first filter plate, and then drives the vibration of the fruit particles and nut shells above. This operation is conducive to the full shelling of the semi-shelled nuts, and then they fall onto the circular filter plate. At this time, the vibration of the first filter plate drives the vibration of the fixed connection block through the connecting rod, and then drives the vibration of the filter connecting plate and the circular filter plate. Then turn on the motor, the motor drives the rotation of the shaft, and then drives the rotation of the circular filter plate on the filter connecting plate, thereby driving the vibration and rotation of the fruit particles and nut shells above, and finally making them fall onto the holding plate; after multiple vibrations and filtering, it is conducive to the complete separation of the fruit particles and nut shells, and the dust generated by the shelling work in the device box can be sucked out by turning on the dust suction fan.
