When the spline 17 is docked with the second key cylinder 18, the first connecting plate 10 and the second connecting plate 11 can keep the fixing ring 12 facing upward, thereby realizing the function of automatic engagement after docking.

[0033] Embodiment 2:

[0034] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0035] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the first support seat 1, the fixed rod 2, the connecting rod 3, the bracket 4 and the outer sleeve 7 are a whole, and the support seat 1 is symmetrically distributed on both sides below the first connecting plate 10 to ensure that the device as a whole can be stably supported, and a conveyor belt 15 is arranged between two adjacent first support seats 1, and the screened chestnuts can be subsequently transported by the conveyor belt 15.

[0036] like Figure 1 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the inner wall of the outer bushing 7 and the outer wall of the connecting shaft 8 are fitted with each other, and the connecting shaft 8 can rotate smoothly inside the outer bushing 7, and the outer bushing 7, the connecting shaft 8 and the connecting plate 9 are symmetrically distributed on the left and right sides of the first connecting disk 10, ensuring that the device can dump the remaining chestnuts after the screening is completed.

[0037] like Figure 1 and Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the height of the fixing ring 12 is greater than the thickness of the second connecting disk 11, and the through hole 13 on the second connecting disk 11 has the same aperture as the through hole 13 on the first connecting disk 10. The device can change the screening effect of the device by changing the degree of staggering of the through holes 13 on the first connecting disk 10 and the second connecting disk 11, thereby enhancing the adjustability of the device to facilitate subsequent screening of chestnuts of different sizes.

[0038] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the adjustment component 16 includes a fixed shaft 1601 fixedly connected to the bracket 4, a swivel 1602 is fixedly provided at the bottom of the fixed shaft 1601, a second electric push rod 1603 is installed on the swivel 1602, the second electric push rod 1603 is fixedly provided with a connecting ring 1605, a connecting block 1604 is rotatably provided in the connecting ring 1605, the connecting block 1604 and the spline 17 are fixedly connected, and the connecting block 1604 and the first key cylinder 6 are slidably connected. The device can make the connecting ring 1605 drive the connecting block 1604 and the spline 17 to move up and down by extending or shortening the second electric push rod 1603, so as to subsequently turn over the chestnuts inside the device to achieve a more efficient screening effect.

[0039] like Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the fixed shaft 1601, the swivel 1602, the second electric push rod 1603 and the bracket 4 are a whole, the spline 17 is suitable for being connected with the second key cylinder 18 when the second electric push rod 1603 is extended, and the material of the spline 17 is rubber material. The spline 17 made of rubber material can bend and dock with the second key cylinder 18 when the position of the second key cylinder 18 is offset, so that the device can still be used normally after adjusting the screening size, thereby enhancing the adaptability of the device.

[0040] like Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the stirring rod 19 and the second connecting disk 11 are rotatably connected, the through holes 13 are evenly distributed on the first connecting disk 10 and the second connecting disk 11, and the rotatably installed stirring rod 19 can turn over the chestnuts on the device when rotating, and the evenly distributed through holes 13 can ensure the screening effect of the device.

[0041] Specifically, when the chestnut size screening device is used: Figure 1-Figure 3 and Figure 5As shown, when the device is working, the first electric push rod 14 is extended or shortened according to the required screening effect, thereby changing the left and right position of the second connecting disk 11 below the fixed ring 12 on the first connecting disk 10, thereby adjusting the overlapping area of ​​the through holes 13 at various locations on the first connecting disk 10 and the second connecting disk 11, and changing the screening size of the device. The larger the overlapping area of ​​the through holes 13 on the first connecting disk 10 and the second connecting disk 11, the larger the screening size. During the screening process, the rubber spline 17 needs to be docked with the second key cylinder 18.

[0042] like Figure 2-Figure 4 As shown, when the spline 17 is docked with the second key cylinder 18, the height of the connecting ring 1605 is changed by extending the fixed shaft 1601 and the second electric push rod 1603 under the rotating ring 1602, and the connecting block 1604 that is rotatably connected in the connecting ring 1605 will drive the spline 17 to move up and down. The spline 17 made of rubber material can dock with the second key cylinder 18 after rotation. At this time, the motor 5 can be started to drive the first key cylinder 6 to rotate, thereby driving the spline 17, the second key cylinder 18 and the stirring rod 19 to rotate. The stirring rod 19 flips the chestnuts in the device to realize the screening function. After the screening is completed, the overlapping area of ​​the through holes 13 on the first connecting disk 10 and the second connecting disk 11 can continue to be adjusted to realize the next screening. The remaining chestnuts can be transported by shortening the second electric push rod 1603. At this time, the spline 17 is no longer connected to the second key cylinder 18. By rotating the connecting shaft 8 in the outer bushing 7, the connecting plate 9, the first connecting disk 10 and the second connecting disk 11 are rotated, and the remaining chestnuts are poured onto the conveyor belt 15 to transport chestnuts of larger size.

[0043] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
