Crop lifting and conveying mechanism

Abstract

The invention relates to a crop lifting and conveying mechanism, which comprises a casing, and two ends of the casing are respectively provided with a material inlet and a material outlet, and a downwardly convex filter is arranged inside the inlet, and a There is a support ring; the lower convex surface of the filter screen is in contact with the support ring. The technical solution can effectively restrain the vibration of the grain on the second filter screen through the existence of the grain accommodation cavity, so as to prevent the grain grain from "jumping" above the feed inlet, thereby causing the grain to spill out.

Description

technical field [0001] The invention relates to a crop lifting and conveying mechanism, which belongs to the technical field of conveying machinery and equipment. Background technique [0002] Cereals generally refer to rice, wheat, millet, soybeans, etc. and other granular food fruits. Most of the existing grains are harvested by mechanization. After harvesting, centralized threshing is carried out to separate the straw from the grain. However, limited by the separation accuracy of the existing equipment, the grain is still mixed with a small amount of impurities such as straw and awn after separation. Although it does not affect the storage of grains, in order to meet the requirements of food safety, other impurities must be completely removed before the grains are further processed. Therefore, most grain processing enterprises use special lifting field equipment to efficiently screen grains to improve the separation accuracy of impurities. However, this method requires a...

Problems solved by technology

Most of the existing grains are harvested by mechanization. After harvesting, centralized threshing is carried out to separate the straw from the grain. However, limited by the separation accuracy of the existing equipment, the grain is still mixed with a small amount of impurities such as straw and awn after separation. Although it does not affect the storage of grains, in order to meet the requirements of food safety, other impurities must be completely removed before further processing of grains

Therefore, most grain processing enterprises use special lifting field equipment to efficiently screen grains to improve the separation accuracy of impurities, but this method requires a large investment in equipment, which is not conducive to the large-scale promotion of the field of agricultural product processing
