Baffling grain winnowing machine

Abstract

The invention discloses a baffling grain winnowing machine. The baffling grain winnowing machine comprises a support box and a turnover box, and is characterized in that the support box is a rectangular box body; support legs are symmetrically arranged on the left and right two sides of the support box; the turnover box is arranged on the left side of the upper end of the support box; a communicating pipe is arranged between the left lower end of the support box and the turnover box; the upper end of the communicating pipe is leveled with the inner bottom surface of the turnover box; a guide inclined plate is arranged at the bottom of the turnover box in a left-low and right-high manner; the left end of the guide inclined plate is leveled with the inner bottom surface of the turnover box; two separation plates are arranged at the inner bottom of the support box in parallel for dividing the support box into three collecting areas; the three collecting areas are respectively a sand grain collecting hopper, a grain collecting hopper and a dryup material collecting hopper; and the turnover box is a rectangular box body. The baffling grain winnowing machine is simple and reasonable in structure, excellent in winnowing effect and excellent in dust removing and drying effect, reduces the production cost, and is high i practicability.

Description

technical field [0001] The invention relates to a wind separator, in particular to a baffle type grain wind separator. Background technique [0002] Agriculture has been the foundation of the national economy since ancient times. In order to realize the economic take-off and the improvement of comprehensive strength of our country, our country has been exploring the road of agricultural development, and has made great achievements in agricultural technology, economy and various aspects. But now China's agriculture has problems in society, economy and ecology, etc., which seriously restrict the development of agriculture. The development of my country's agriculture must set clear goals, choose an agricultural development model suitable for my country's actual conditions, and finally realize agricultural modernization.

Problems solved by technology

But now China's agriculture has problems in society, economy and ecology, etc., which seriously restrict the development of agriculture. The development of my country's agriculture must set clear goals, choose an agricultural development model suitable for my country's actual conditions, and finally realize agricultural modernization. For a long time, agriculture It is an indisputable fact that the profit level of the production link is not high. On the one hand, it is due to the long-term impact of the national development strategy of supporting industrial development with agriculture for many years. On the other hand, it is also due to the fact that the vast majority of agricultural producers are scattered and weak. And the barriers to entry are low, and they do not have the bargaining power of the industry chain

In addition, the prices of raw materials and agricultural materials have generally risen, and the prices of chemical fertilizers, greenhouse films, and diesel have increased significantly in the past few years, pushing up the cost of agricultural production

Although the price of agricultural products has also risen, because agriculture is related to the food problem of hundreds of millions of people, the government has adopted certain control measures on the price increase of terminal agricultural products, which will have a certain negative impact on the overall profit level of agriculture

Especially in some hilly areas, the field area is small, the distribution is diffuse, it is difficult to use large-scale machinery for centralized development, the harvest of grain is small, and the grain contains gravel, shriveled grains, etc., large-scale machinery is uneconomical and costly

[0003] In order to solve the above-mentioned problems, the patent with the existing patent notification number CN205308789U discloses a kind of winnowing machine, but this device arranges winnowing and dust removal in one program, and then affects the winnowing effect of the device, and in this kind of device The turning effect of the material is poor, which leads to poor dust removal and drying effects of the device
