Description

Technical Field

[0001] The utility model relates to the technical field of seed selection devices, in particular to a soybean seed selection device. Background Art

[0002] The main function of the soybean seed selection device is to improve the quality and germination rate of seeds and ensure the high yield and high quality of crops. The working principle of the soybean seed selection device mainly involves screen vibration screening and airflow screening. Screen vibration screening is to let soybeans enter the machine casing from the feed inlet. Through the vibration of the screen, smaller impurities and broken beans are screened out, while larger intact beans fall through the coarse screen.

[0003] When the existing soybean seed selection screen vibration screening machine is in use, soybeans are fed into the machine casing from the feed port and screened by the vibration of the screen. However, after the screening is completed, soil and impurities will remain on the screen and cause blockage, thereby affecting the next use. At the same time, the long-term accumulation of impurities and soil will also damage the screen and reduce its service life. Therefore, to address the above problems, we provide a soybean seed selection device. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, a cleaning device is formed by arranging a push rod, a brush assembly, an internal threaded sleeve, a magnet and an iron handle. When the screen plate assembly has finished screening the soybeans, the internal threaded sleeve is rotated outward so that the internal threaded sleeve is separated from the threaded ring on the push rod, and then the internal threaded sleeve is moved to the right close to the iron handle, so that the magnet and the iron handle are magnetically attracted to each other and fixed, and then the iron handle is pushed to the left, and the iron handle drives the push rod and the brush assembly to move to the left, so that the brush assembly can clean the dirt and impurities on the screen plate assembly in time, so as not to affect the next use.
