[0028] The feeding assembly 1 comprises a feeding hopper 11, a feeding pipe 13 is arranged at the bottom of the feeding hopper 11, and a solenoid valve 12 is arranged on the feeding pipe 13;

At the same time, because the nut shell is cut first and then pressure is applied, the force is smaller than that of the traditional direct pressure crushing device, thereby protecting the nut kernel and ensuring the integrity of the nut kernel.

[0032] Working principle: When the nut shelling machine is used, the solenoid valve 12 is automatically opened first, and the nuts in the upper hopper 11 fall into the grooves on the surface of the conveying chain plate 74 through the discharge pipe 13. At this time, the negative pressure fan 76 is started, and the nuts are firmly adsorbed in the grooves of the conveying chain plate 74 under the action of negative pressure. Then, the conveying chain plate 74 is driven by the third motor 72 to drive the nuts to be slowly conveyed to the cutting assembly 5. When the nuts move to the bottom of the blade 54, the lead screw slide 59 drives the first connecting plate 51 and the components at the bottom of the first connecting plate 51 to synchronously decrease in height, so that the blade 54 moves to one side of the nut. Then, the first hydraulic cylinder 511 pushes the slider 52 to slide at the bottom of the first connecting plate 51. During the sliding process of the slider 52, the first fixed plate 53 and the blade 54 at the bottom of the first fixed plate 53 are driven to approach the nut. The blade 54 completes the cutting of the nut shell during the rotation process. When the cutting work is completed, the blade 54 is reset, and then the conveying chain plate 74 continues to drive the nut to be conveyed to the bottom of the shell pressing assembly 6. When the nut moves to the bottom of the pressing column 64, the second hydraulic cylinder 61 pushes the pressing column 64 downward to press the nut shell to complete the crushing of the nut shell. At the same time, the negative pressure fan 76 is closed, and then the conveying chain plate 74 continues to drive the nut shell and nut kernel to move close to the lower hopper 4. The conveying chain plate 74 pours the nut shell and nut kernel in the groove out and discharges them from the lower hopper 4 during the rotation process.
