The chestnut baffle 8 is vertically fixed on the inner wall of the box, and the chestnut baffle 8 is located above the first guide inclined plate 17. It is used to block the chestnuts and allow a small number of chestnuts to flow through the first guide inclined plate 17 to the first top plate 14. A fixed guide plate 16 is slidably disposed between the first top plate 14 and the second top plate 15. The fixed guide plate 16 is fixedly connected to the box body. The bottom end of the first guide inclined plate 17 is attached to the side of the first top plate 14. The upper surfaces of the first top plate 14, the fixed guide plate 16, and the second top plate 15 are all inclined surfaces, facing the chestnut cutting chamber 2, and the width of the inclined surface can only accommodate one row of chestnuts. Chestnuts are placed on the first guide inclined plate 17 and roll along it to one side of the first top plate 14. The motor reducer 11 drives the first top plate 14 to descend to a position lower than the lower end of the first guide inclined plate 17. The chestnuts fall freely onto the upper inclined surface of the first top plate 14. The motor reducer 11 drives the first top plate 14 to rise. After the first top plate 14 passes the fixed guide plate 16, the chestnuts slide smoothly into the upper inclined surface of the fixed guide plate 16. The motor reducer 11 drives the first top plate 14 and the second top plate 15 to descend simultaneously. The first top plate 14 begins the next round of feeding, while the second top plate 15 descends past the inclined surface of the fixed guide plate 16, and the chestnuts slide into the upper inclined surface of the second top plate 15.

The chain of the sprocket drive structure is externally connected to the lower drive shaft 261, so that the upper drive shaft 251 and the lower drive shaft 261 rotate in opposite directions to ensure that the chestnut passes through smoothly. A guide drive sprocket 7 is also provided inside the main transmission box 21. The guide drive sprocket 7 is located between the lower transmission shaft 261 and the output shaft 231. The guide drive sprocket 7 is used to guide the chain of the sprocket drive structure and increase the contact length between the chain and the sprocket on the lower transmission shaft 261.

[0028] A second vibration motor 2211 is installed on the guide baffle 221, and a first vibration motor 171 is installed on the lower surface of the first guide inclined panel 17 to realize the vibration of the guide baffle 221 and the first guide inclined panel 17, thereby assisting the chestnut to be fed smoothly.

[0029] Working principle: Using the pull arm 12 and connecting rod 13, the first top plate 14 and the second top plate 15 are driven by the motor reducer 11 to reciprocate through the fixed guide plate 16, pushing a row of individual chestnuts into the second guide inclined plate 22 in sequence. Then, they automatically slide through the feeding roller 24 and the third guide inclined plate 29 into the space between the upper conveyor belt 25 and the lower conveyor belt 26. After passing through the circular blade assembly 27, they are cut open and then sent out. The guide baffle 221 divides and guides the chestnuts, while the movable baffle assembly 223 and the V-shaped guide elastic clamp 28 comb the chestnuts, so that individual chestnuts enter the upper conveyor belt 25 and the lower conveyor belt 26 in sequence.

[0030] Example 2: Please refer to Figure 10 This utility model provides a technical solution: a novel chestnut cutting machine, including: a feeding bin 1.
