After the circular plate 301 is inverted, the feeding square tube 3073 is facing downward, and the electromagnets 4079 on each height fixed box 4071 are controlled to be energized in turn, thereby generating attraction for the second magnetic block 40717, so that the clamping rod 40711 moves upward and disengages from the clamping groove 40712, and the first magnetic block 4078 moves under the action of the attraction of the electromagnet 4079, so that the plug plate 4075 pulls the longitudinal baffle plate 3091 to rotate and open, so as to facilitate the batch unloading of the screened camellia fruits and avoid re-mixing during unloading.

[0024] Working principle: When working, firstly, the second motor 405 controls the screw rod 404 to rotate, and then drives the longitudinal rod 401 to move downward, and then drives the double-sided toothed plates 40616 to move downward. Since the double-sided toothed plates 40616 and the guide rod 40615 are meshed and connected with the third gear 40621, the double-sided toothed plates 40616 move downward and drive the guide rod 40615 to move upward, thereby pulling the clamping rod 40611 to move toward the inside of the movable groove 4069, so that the clamping rod 40611 is disengaged from the clamping groove 4063, and then the longitudinal rod 401 continues to move downward, and the two horizontal baffle plates 4066 are pushed to rotate downward around the fixed axis 4061 through the first connecting rod 4068, and then the feed The camellia fruits to be screened are inputted at the top of the square tube 3073, so that all the camellia fruits enter the inner side of the first annular plate 3071, and then the longitudinal rod 401 is controlled to move back upward, first driving the transverse baffle plate 4066 to rotate upward until the top wall of the transverse baffle plate 4066 is in close contact with the bottom wall of the feeding square tube 3073, and then the double-sided toothed plates 40616 are controlled to move upward relative to the sliding beam 4064, thereby driving the guide rod 40615 to move downward, and the clamping rod 40611 is pushed outward by the second connecting rod 40613 to be clamped in the clamping groove 4063, thereby fixing the sliding beam 4064, thereby preventing the camellia fruits from falling out of the feeding square tube 3073 when the circular plate 301 rotates; When feeding, since the longitudinal baffle plate 3091 is located at the side of the discharge side groove 308 close to the inner side of the feeding square tube 3073, the discharge side groove 308 is closed, thereby preventing camellia fruits from directly entering the discharge side groove 308 during feeding, thereby improving the guiding effect on the camellia fruits. At the same time, when the longitudinal rod 401 moves downward, the plug plate 4075 is driven to move downward. Since the plug plate 4075 is located inside the plate groove 3096, and the clamping rod 40711 is clamped in the clamping groove 40712 at this time, the pull rod 4074 is fixed to the fixed box 4071, so that the longitudinal rod 401 moves downward, and the extrusion block 4076 generates a thrust on the pressure block 3099, pushing the slide plate 3098 to move toward the side of the longitudinal baffle plate 3091, so that the first spring 30910 is compressed, and then the longitudinal baffle plate 3091 is pressed by the elastic force of the first spring 30910, further improving the feeding effect of camellia fruits. Then, the first motor 305 is turned on to rotate the second gear 304, and the circular plate 301 is driven to swing continuously through the first gear 303. During the swinging process, the camellia fruits inside the first annular plate 3071 are continuously rolled. During the rolling process, the small camellia fruits and the medium-sized camellia fruits enter the inner side of the second annular plate 3072 through the first screening holes 3074, while the large camellia fruits remain in the first annular plate 3071, and the small camellia fruits enter the inner side of the circular plate 301 through the second screening holes 3075, and the smallest camellia fruits fall out of the third screening holes 3076 to the inside of the bottom box 1, thereby completing the screening of camellia fruits of different sizes; When it is necessary to discharge the fruits, the circular plate 301 is adjusted to an inverted state so that the feeding square tube 3073 is set downward, and then the two longitudinal baffle plates 3091 corresponding to the circular plate 301 are controlled to open in sequence so that the small camellia fruits are discharged first, and then the longitudinal baffle plates 3091 corresponding to the second annular plate 3072 are controlled to open so that the medium-sized camellia fruits are discharged, and finally the longitudinal baffle plates 3091 corresponding to the first annular plate 3071 are controlled to open so that the large camellia fruits are discharged; When the longitudinal baffle plate 3091 is discharged, the control electromagnet 4079 is energized to generate attraction for the first magnetic block 4078 and the second magnetic block 40717. When the second magnetic block 40717 is attracted, it drives the transverse rod 40714 to move toward the longitudinal rod 401, and pulls the engaging rod 40711 upward through the third connecting rod 40715 to disengage from the engaging groove 40712. Then, the first magnetic block 4078 pulls the plug plate 4075 toward the side of the longitudinal rod 401 under the action of attraction. Since the plug plate 4075 is located inside the plate groove 3096, the longitudinal baffle plate 3091 is pulled outward to open the discharge side groove 308 for discharge.
