Description

Technical Field

[0001] The utility model relates to the field of radish seeds, in particular to a threshing and screening machine for radish seeds. Background Art

[0002] Radish is a biennial or annual herbaceous plant of the genus radish in the family Cruciferae. It has a taproot that is fleshy, oblong or conical, with a green, white or red outer skin. The stem has hairless branches. The leaves are large, pinnate, and semi-cleft, with blunt teeth and sparsely covered with coarse hairs. The flowers are white or pink, and the petals are obovate with purple stripes. When processing radish seeds, a screening machine is needed to screen and classify the radish seeds.

[0003] After searching, the application number is "202222536335.8", which provides a new type of radish seed threshing and screening machine. Since the three sets of fans are in the turned-on state, when the radish seeds fall and pass through the front end of the fan, the fan can be aligned with the gap between the baffle and the partition and the air outlet, and the wind force of the fan can blow out some lighter shriveled seeds or seed skins in the radish seeds from between the baffle and the partition and in the collection box, while those heavier seeds will continue to fall down on top of the screening plate. The vibration generated by the small vibration motor on the upper ends of the two connecting plates and the elasticity of the two springs under the two connecting plates make the screening plate vibrate up and down and left and right, and the radish seeds falling on the screening plate are screened for the second time. The above-mentioned vibrating screen plate screens the radish seeds, which is convenient for the processing of radish seeds. However, after the screening of the radish seeds is completed, large seeds will remain on the screen plate. When the amount of residual seeds is large, the screen plate is easily blocked, affecting the screening effect of the radish seeds next time. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a radish seed threshing and screening machine, which is convenient for screening radish seeds through the screening box, the lifting plate, the screening frame, the rotating shaft, the motor, the gears and the spring, and the motor controls the rotation of the gears to control the flipping of the screening frame, so as to quickly discharge the radish seeds on the screening frame and avoid clogging of the screening frame.
