Sesame harvester screening device

Abstract

The invention relates to a screening device for a sesame harvester. The screening device conducts primary screening of sesame seeds through a vibrating winnowing assembly, and the fan blades in the fan housing generate wind force and blow air to the tail of the winnowing vibrating bucket through the blowing port on the upper part. , the lighter straw that enters the winnowing vibrating bucket from the conical feed hopper is blown away, and the pulley A drives the rotating shaft through the pulley B, and the rotating shaft passes through the eccentric wheel and the driving connecting rod A and driving connecting rod B to continuously push and pull the winnowing vibration The air selection vibrating bucket shakes back and forth at the front end of the frame through the connecting rods hinged at both ends, and the screening effect is better when the air selection is accompanied by the front and rear shaking; body, the screening shell shakes back and forth at the rear end of the frame through the connecting rod, and the multi-layer screening plate screens out the heavier straws step by step; Step by step screening, the screening process is more refined and cleaner, which improves the overall screening efficiency.

Description

technical field [0001] The invention relates to the technical field of sesame harvesters, in particular to a screening device for sesame harvesters. Background technique [0002] Sesamum (Sesamum indicum L.) is a herbaceous plant belonging to the family Linaceae, mainly planted in Asia and Africa, with high economic and nutritional value. Sesame has been cultivated in my country for more than 2,700 years. It is rich in functional health substances such as unsaturated fatty acids, vitamin E, sterols, and sesamin. Chinese consumers love it. The development of sesame production in suitable regions and soils has broad economic and social prospects. In recent years, my country's demand for sesame has been increasing, and it has become the world's largest consumer and importer. However, the current domestic production and supply of sesame is only about 40%. Improving the self-sufficiency rate of sesame is an urgent problem to be solved. [0003] The traditional production mode o...

Problems solved by technology

[0003] The traditional production mode of sesame is manual harvesting at maturity, including complex processes such as cutting, binding, scaffolding, drying, threshing, cleaning, and straw handling, which is time-consuming and laborious

With the advancement of technology, a combine harvester for sesame appears on the market. After the sesame is crushed, the sesame seeds are separated by the screening device in the combine harvester. The sesame seeds are smaller in size and denser when they are gathered together. , the screening procedure of the screening device in the existing combine harvester is relatively simple, and the screening effect on the sesame seeds mixed with finely crushed straw is not good. Screening, prolonging the entire operating procedure, the efficiency is not high, so it is necessary to design a screening device for sesame harvester
