Description

Technical Field

[0002] Crop seeds refer to plant seeds used in agricultural production and are one of the most basic means of production in agricultural production. The quality standards for crop seeds include purity, clarity, germination rate, moisture content and other indicators. The seed quality standards for different crops vary.

[0003] When producing crop seeds, cleaning and removing impurities from the seeds is an important part of improving seed quality. Water sorting is one of the common methods. Water sorting uses the different specific gravities of seeds and impurities to separate them. It is common to pour the seeds into a centrifuge, and the centrifuge is located in a cleaning box and immersed in the water flow of the cleaning box. As the centrifuge rotates, the seeds inside the centrifuge can be stirred and cleaned, thereby achieving cleaning and removing impurities from the seed particles.

[0004] However, in order to ensure the stability of the centrifuge barrel during operation, the centrifuge barrel is usually directly installed in the cleaning box by rotating through the transmission shaft. In this way, after the seed particles are cleaned and removed, the seed particles inside the centrifuge barrel need to be manually dug out little by little. Since the centrifuge barrel is barrel-shaped, the efficiency of digging out the seeds decreases as the seeds inside the centrifuge barrel decreases, which will affect the efficiency of seed washing and thus has certain defects.

The shielding box drives the top cover assembly to rise, so that the centrifugal cylinder can be directly removed, so as to facilitate the removal of the seed particles inside the centrifugal cylinder. (2) The present invention utilizes a configuration in which a centrifugal cylinder and a top cover assembly cooperate. The top cover assembly includes a shielding cover, a limiting frame, a limiting frame, a floating block and a connecting ring. The limiting frame and the limiting frame are used in combination to ensure the stability of the centrifugal cylinder during operation. When cleaning impurities inside the centrifugal cylinder, water is injected into the shielding box and is higher than the height of the centrifugal cylinder. Under the action of the water flow, the shielding cover can float up and separate from the centrifugal cylinder, so that the floating impurities are discharged from the top of the centrifugal cylinder. When drying the seed particles inside the centrifugal cylinder, the shielding cover can shield the top of the centrifugal cylinder under the action of the limiting spring to prevent the seeds inside the centrifugal cylinder from spilling out due to the centrifugal force when the centrifugal cylinder rotates.
