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 new screening device for sesame harvester

Abstract

The invention relates to a novel sesame harvester screening device. According to the novel sesame harvester screening device, sesame seeds are primarily screened through a vibration type winnowing assembly, fan blades in a fan cover generate wind power and blow air to the tail part of a winnowing vibration hopper through an air blowing opening in the upper part, and light straw entering the winnowing vibration hopper from a conical feeding hopper is blown away; a belt wheel A drives a rotating shaft to rotate through a belt wheel B, the rotating shaft continuously pushes and pulls the winnowing vibration hopper through an eccentric wheel and a driving connecting rod, the winnowing vibration hopper shakes front and back at the front end of a rack through a connecting rods hinged to the twoends, and the screening effect of front-back shaking during winnowing is better; and the winnowing vibration hopper shakes to continuously push and pull a screening shell through the lower part of a connecting rod A, the screening shell shakes front and back at the rear end of the rack through the connecting rod, and the multiple layers of screening plates screen out straw with heavy mass step bystep. Sesame mingled with the straw is screened step by step through vibration winnowing and vibration screening, the screening process is finer, screening is through, and the overall screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sesame harvesters, in particular to a novel 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 ...
