Abstract

The invention discloses a teff combined type cleaning system and a teff threshing and cleaning machine. The teff combined type cleaning system comprises a rack, a vibrating screen assembly and an airflow cleaning device, wherein the vibrating screen assembly and the airflow cleaning device are arranged on the rack; the vibrating screen assembly is used for screening away long straw and weeds whichare obtained after teff threshing; a seed discharge port of the vibrating screen assembly is connected with the airflow cleaning device; after being adsorbed by the airflow cleaning device, seeds aredischarged from the seed discharging port of the vibrating screen assembly, and shells in the seeds and the fine straw are discharged from an impurity removal port of the airflow cleaning device. Thecombined type cleaning system is provided with the teff threshing and cleaning machine and comprises a feeding device, a threshing device, a combined type cleaning system body, an engine device and awalking land wheel. The teff threshing and cleaning machine is reasonable in structure matching, convenient to operate, simple in test process and reliable to apply, and a solution is provided for obtaining the clean teff seeds.

Description

technical field [0001] The invention relates to the technical field of harvesting of small seed crops, more specifically, to a combined cleaning system for teff seed crops and a teff threshing and cleaning machine. Background technique [0002] Teff is the main food crop in Ethiopia and is widely planted. At present, the agricultural production of teff mainly relies on labor and animal power. The production method is backward and the production efficiency is low. It is extremely difficult to meet the demand for teff due to population growth. Threshing and cleaning are one of the most important links, mainly relying on manual harvesting, drying on the field, manual threshing with cattle treading, and then using natural wind for manual cleaning. Due to the small size of teff grains, the thousand-grain weight is only 0.26-0.42g, and the grain-to-grass ratio is very small, and the amount of straw is large, among which there are many very fine straws. After threshing and crushin...
