Problems solved by technology
[0002] In the production of traditional crops, it is usually necessary to separate and screen the fruits to obtain fruits with uniform quality, such as corn and sorghum after machine threshing, there will always be many broken and incomplete particles in the cereal fruits just after harvesting, and Nowadays, with the improvement of living standards, people have higher requirements on the quality and appearance of grains. The existing grain screening and separation equipment has a complex structure, especially the vibration structure, which has high production costs and poor separation effect, which is not conducive to promotional use

The invention discloses a grain vibration screening device which comprises a machine frame, a vibration mechanism and a screen located on the vibration mechanism. The vibration mechanism comprises a V-shaped block. A through hole is formed in the sharp corner of the V-shaped block. The V-shaped block is movably arranged on a central shaft in a sleeving mode through the through hole. The top end of the central shaft does not extend out of the upper port of the through hole. The upper port of the through hole is connected with the bottom of a screen pot. The screen is arranged in the screen pot. Rectangular blocks are hinged to the two end points of the opening end of the V-shaped block respectively. A polished shaft capable of freely moving in the rectangular block is arranged in each rectangular block in a penetrating mode. The polished shaft on the left side is fixedly connected with and is parallel to a flat plate on an output shaft of a motor. The polished shaft on the right side is connected with and is parallel to a mandrel through a connecting plate and can rotate around the mandrel. The distance between the polished shaft on the left side and the output shaft of the motor is equal to the distance between the polished shaft on the right side and the core shaft. The grain vibration screening device is simple and compact in structure, high in work efficiency and good in separation screening effect.
Description
technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to grain screening and separation equipment. Background technique [0002] In the production of traditional crops, it is usually necessary to separate and screen the fruits to obtain fruits with uniform quality, such as corn and sorghum after machine threshing, there will always be many broken and incomplete particles in the cereal fruits just after harvesting, and Nowadays, with the improvement of living standards, people have higher requirements on the quality and appearance of grains. The existing grain screening and separation equipment has a complex structure, especially the vibration structure, which has high production costs and poor separation effect, which is not conducive to Promotional use. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a grain vibration screening d...
