Seed threshing and cleaning device

Abstract

The embodiment of the invention provides a seed threshing and cleaning device, and relates to the field of agricultural machinery. The seed threshing and cleaning device comprises a rack, a roller threshing mechanism, a vibration screening mechanism, a material conveying mechanism and a driving mechanism, wherein the roller threshing mechanism is arranged at the top of the rack, the vibration screening mechanism is arranged in the middle of the rack and located below the roller threshing mechanism, the material conveying mechanism is arranged at the bottom of the rack and located below the vibration screening mechanism, and the driving mechanism is arranged on one side of the rack and is in transmission connection with the roller threshing mechanism, the vibration screening mechanism and the material conveying mechanism. Compared with the prior art, the seed threshing and cleaning device can achieve the function of threshing, cleaning and conveying forage grass seed; and meanwhile, thecleaning effect can be improved by adopting a multi-layer vibration woven screening mode, and the rate of impurities in the seeds is low.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a seed threshing and cleaning device. Background technique [0002] Grass seeds are an important material basis for obtaining high-quality forage grass, controlling grassland degradation, improving grassland productivity, improving ecological environment, and realizing sustainable development of animal husbandry. The production of forage seeds is also a major measure to promote the modernization of animal husbandry and the development of agricultural economy in our country, which is of great significance to the success of economic development and ecological construction in our country. Grass seed industry is a sunrise industry full of vitality, which can definitely become the highlight of my country's agricultural structure adjustment and a new growth point of national economic development. The development of the forage seed industry is conducive to promoting the adjustment...

AI Technical Summary

Problems solved by technology

Forage seeds are small in size, light in weight, surrounded by pods on the outside, special in shape, and inconsistent in maturity, which brings difficulties to the threshing, cleaning and harvesting of forage seeds

[0003] At present, forage seeds are mostly directly harvested by grain harvesting machinery, which has poor adaptability and cannot effectively realize the functions of threshing, screening, and transportation of forage seeds.
