Teff threshing and sorting machine

Abstract

The invention discloses a teff threshing and sorting machine. The machine comprises a rack, a threshing device, a conveying device, a sorting device and a driving device, wherein the threshing deviceis arranged at the upper part of the rack and used for teff threshing and long straw discharging; the conveying device is arranged below the threshing device, the sorting device is arranged at the discharging end of the conveying device, and the threshing device and the conveying device are in driving connection with the driving device separately; teff falls into the conveying device after being threshed by the threshing device, and is conveyed to the sorting device; the sorting device is a wind power sorting device and is used for separating threshed seeds from shells and the fine straw. Thethreshing device, the conveying device and the sorting device are arranged on the rack and complete the threshing work of the teff in sequence, and the threshed seeds, the shells and the fine straw are separated by the aid of the wind power sorting device, so that the threshing rate of the teff is greatly increased, the loss rate caused by mixing is reduced, the impurity content of the teff is reduced, and a solution is provided for threshing and sorting of teff crops.

Description

technical field [0001] The invention relates to the technical field of harvesting small seed crops, in particular to 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 crushing, many short and thin straws, seeds, and glumes will be pr...
