Description

Technical Field

[0001] The invention relates to the field of oat washing machines, and in particular to a water-circulating oat washing device and a washing method for graded cleaning of multiple impurities. Background Art

[0002] During the harvesting and transportation process, wheat grains will be mixed with some impurities. Therefore, the wheat grains need to be cleaned before processing. However, the existing cleaning devices can only wash away the dust attached to the surface of the wheat grains, but cannot separate the impurities such as gravel and crushed stones mixed in the wheat grains, and the cleaning quality is limited.

[0003] To this end, Chinese patent application CN116139966A discloses a wheat washing machine utilizing circulating water, which adopts a graded cleaning method to clean impurities in the wheat grains. First, impurities in the wheat grains whose weight is less than the weight of the wheat grains are cleaned through a first cleaning mechanism, and then gravel and cleaning water are passed into a water collecting cover through a first filter plate. The gravel is screened out and retained in the water collecting cover by a second filter plate, and the gravel in the water collecting cover can be discharged from the discharge hopper through a pushing mechanism. When the wheat grains and larger impurities enter the transfer pipe, the larger impurities can be screened out through the second cleaning mechanism, so that the wheat grains can directly enter the dehydration cylinder, and the gravel, dust and larger impurities in the wheat grains can be automatically separated, thereby improving the effect of wheat washing.

[0004] However, due to the different sizes of impurities, some impurities or wheat grains will be stuck in the filter holes of the filter plate during the long screening process, affecting the filtering efficiency of the filter plate. After the impurities and wheat grains are mixed, some impurities are closely combined with the wheat grains during screening, resulting in low screening efficiency and some impurities cannot be successfully screened out.
