Anti-material-blocking conveyor for cereal grain lifting

Abstract

The invention relates to an anti-material-blocking conveyor for cereal grain lifting and belongs to the technical field of mechanical conveying equipment. The anti-material-blocking conveyor comprises a shell. A feeding opening and a discharging opening are correspondingly formed in the two ends of the shell. A lower-protruding filter screen is arranged in the feeding opening. A support ring is arranged below the filter screen. An ultrasonic vibration generator is arranged beside the support ring. The lower protruding face of the filter screen is in contact fit with the support ring. According to the technical scheme, through the combined design of the filter screen and the ultrasonic vibration generator, cereal grains in the filter screen can be promoted to collide with one another, and for some impurities which are entangled with cereal and difficult to separate, the filtering efficiency of the cereal can be improved remarkably.

Description

technical field [0001] The invention relates to an anti-blocking material conveyor used for lifting grain particles, and belongs to the technical field of conveying machinery 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,...

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
