[0002] Peanut kernels refer to the part after removing the peanut shells. In fact, they are the seeds of peanuts. The whole peanut is called a fruit, a pod, and is also called peanut kernels, also known as groundnuts, earth nuts, and Tang people's beans. Peanuts are rich in nutrition and can prolong life. Therefore, they are also called "longevity fruits" among the people. And like soybeans, they are known as "plant meat" and "the meat among vegetables". Before storing peanut kernels, it is necessary to screen them to determine their different qualities.
[0003] At present, manual screening for peanut seed selection is slow and labor-intensive. Therefore, a vibrating screen is usually used to screen peanut seeds. The peanut seeds are directly poured into the vibrating screen for screening. However, the peanut seeds fall at a relatively fast speed after being poured, which is prone to missed screening. Moreover, when there are more peanut kernels entering later, they will pile up with the peanut kernels that entered earlier, reducing the screening effect. For this reason, we propose a screening device for peanut seed selection. Content of the Utility Model
