Problems solved by technology

[0004] The existing grain cleaning machine includes a specific gravity separation table and a grading sieve. The specific gravity separation table and the grading sieve are reciprocally driven by a swing rod to achieve the vibration effect, but the grain cleaning machine vibrates during the grain selection process. Larger, high vibration frequency, easy to cause damage to equipment, short service life, and generate large noise during production, causing damage to the auditory system of on-site workers

Abstract

The invention relates to the field of grain processing equipment, in particular to an electromagnetic type grain winnowing device. The device comprises a screen net, wherein the screen net is fixed ona screen net frame, the screen net frame is a square frame, the opposite sides of the screen net frame are provided with guiding rails, a sliding slot is formed in one side of each guiding rail opposite to the screen net frame, the screen net frame is embedded into the sliding slots of the guiding rails, the other two sides of the screen net frame are fixedly provided with magnets, and one side,back onto the screen net frame, of each magnet is provided with an electromagnet. The electromagnetic type grain winnowing device has the advantages that an electromagnetic driving method is effectively adopted to repeatedly drive a grading screen, and only acts on the movement in the driving direction, compared with a traditional method of adopting a swinging rod to repeatedly drive the grading screen, the vibration is smaller, damage to the device is less likely to be caused, the service life of the device is prolonged, and less noise is generated during the production process, thereby reducing damage to the auditory system of field men.

Description

technical field [0001] The invention relates to the field of grain processing equipment, in particular to an electromagnetic grain selection device. Background technique [0002] Grain selection refers to the cleaning of grain, and is generally used to separate impurities that are different in size, shape, and weight from grain particles, such as stones, mud, metal particles, glass, ceramics, and cinders. [0003] Grain selection is essential in the process of grain harvesting, transportation, and processing. During the harvesting, transportation, and processing of grain, it is inevitable to be mixed with some sundries, including spoiled mold, soil dust, stones, shells or The core straw of corn and other grains must be cleaned of sundries and grains to obtain clean grains before harvesting, transportation and processing. [0004] The existing grain cleaning machine includes a specific gravity separation table and a grading sieve. The specific gravity separation table and th...
