[0018] The present invention provides a Chinese asparagus seed coating device, which has the following beneficial effects:

[0019] 1. The Chinese milk vetch seed coating device, driven by the motor through the shaft tube, drives the turning assembly to make counterclockwise rotation movement inside the tank body with the help of the stirring component. The wing plate can follow the counterclockwise rotation movement of the elliptical tube, and combined with the shielding and guidance of the edge of the wing plate by the side tube strip, the wing plate can guide the Chinese milk vetch seeds to make a short-distance spiral movement along the elliptical tube. In the local space inside the tank body, the Chinese milk vetch seeds located on the left side of the elliptical tube can be periodically and automatically rolled to the right for stirring.

[0020] 2. The milk vetch seed coating device supports the middle parts of the two groups of scraper frames through the ring tube, and is also responsible for connecting the two scraper frames into a whole, so that the two groups of scraper frames can make smooth rotational motion around the shaft tube on the inner side of the tank body under the guidance of the circular trajectory of the ring tube, and a part of the resistance generated by the scraper frames when stirring the milk vetch seeds is shared through the ring tube and the inclined push rod, and at the same time, the inclined push rod can be used to help the stirring assembly to stir the milk vetch seeds near the shaft tube.

[0021] 3. The milk vetch seed coating device can effectively prevent some milk vetch seeds from agglomerating into clumps and being unable to be fully wrapped and mixed by coating agents, ingredients or auxiliary materials through the multi-directional stirring action of the milk vetch seeds by the scraper frame, guide angle frame, inclined push rod, thick tube, wingspan, elliptical tube and wing plate, so that each milk vetch seed can be coated.

[0022] Fourth, the milk vetch seed coating device can use the wingspan to stir the milk vetch seeds near the shaft tube by means of a structural form that elastically extends from the inner side of the card slot while the turning assembly is coating the milk vetch seeds left and right, thereby accelerating the mixing efficiency of the milk vetch seeds near the shaft tube and the ingredients and eliminating dead corners in stirring.

[0023] 5. The Chinese milk vetch seed coating device can use a spring to install two wingspans in a card slot structure to reduce the impact force of the wingspan on the Chinese milk vetch seeds during mixing and stirring, avoid the hard collision of the wingspan on the Chinese milk vetch seeds, and reduce the damage of the Chinese milk vetch seeds during the stirring process by the wingspan. The overall streamlined design of the turning assembly is used to reduce the damage of the turning assembly to the Chinese milk vetch seeds during the stirring process, effectively ensuring that the coating device can efficiently coat the Chinese milk vetch seeds while reducing the damage to the Chinese milk vetch seeds during the coating process, reducing the defective output rate of the Chinese milk vetch seeds, and improving the product quality of the coated Chinese milk vetch seeds.

[0024] 6. The milk vetch seed coating device, by controlling the motor to drive the shaft tube to rotate clockwise inside the tank body, can periodically and automatically roll and stir the milk vetch seeds located on the right side of the elliptical tube to the left in the local space inside the tank body. By periodically changing the rotation direction of the shaft tube inside the tank body, the turning assembly can realize left and right rolling mixing of the milk vetch seeds and ingredients, which can drive the milk vetch seeds to fully contact and mix with the ingredients inside the tank body, realize all-round coating of the milk vetch seeds, and eliminate coating omissions.

[0025] 7. The milk vetch seed coating device rotates in accordance with the direction of the guide angle frame on the scraper frame, and uses the guide angle frame to continuously scrape off the seeds attached to the inner wall of the tank, so that the milk vetch seeds cannot be attached to the inner wall of the tank for a long time, ensuring that all the milk vetch seeds can participate in the stirring movement of the turning assembly and the stirring component.

After all the ingredients are added, the feed pipe 4 is closed, and the turning assembly 6, the scraping assembly 7 and the stirring assembly 8 are driven by the motor 2 to fully stir and mix the Chinese milk vetch seeds. Subsequently, the feed pipe 4 can be used to observe whether the seed coating inside the tank body 1 is completely wrapped to determine whether to open the discharge pipe 9 to discharge the coated Chinese milk vetch seeds.

[0041] The second embodiment is based on the first embodiment. Figures 2 to 5 As shown, an arrow plate 67 is installed at one end of the elliptical tube 61 close to the motor 2, and a plug 68 is connected to the middle of the end of the arrow plate 67 facing the elliptical tube 61. The arrow plate 67 is assembled with the elliptical tube 61 through the plug 68, and the arrow plate 67 is used to shovel seeds onto the wing plate 62; a ring tube 74 is connected to the middle of the scraper frame 72, and the ring tube 74 is installed between the two scraper frames 72, and the ring tube 74 is installed in close contact with the inner wall of the tank body 1, for supporting and guiding the scraper frame 72 to rotate in a circle around the axis of the tank body 1 on the inner side of the tank body 1.

[0042] A tilted push rod 75 is threadedly connected between the scraper frame 72 and the shaft tube 5, and the tilted push rod 75 is symmetrically installed at both ends of the shaft tube 5, which can provide support for the inner side of the scraper frame 72, and the scraper assembly 7 is rotatably installed with the tank body 1 through the shaft tube 5 and the motor 2; the elliptical tube 61 is assembled with the shaft tube 5 through the sleeve 65 and the thick tube 81, and the material turning assembly 6 is rotatably installed with the tank body 1 through the stirring component 8 on the shaft tube 5 and the motor 2, and the entire material turning assembly 6 is arranged within the range covered by the scraper assembly 7.

[0043] When in use, the shaft tube 5 is driven by the motor 2 and the stirring component 8 to drive the turning assembly 6 to make a counterclockwise rotation movement inside the tank body 1.
