Anti-blocking grain baffling type screening machine

Abstract

The invention discloses an anti-blocking type grain baffle screening machine, which comprises a support box and an overturn box fixed on the support box and communicated with the support box. There is a connecting channel between the boxes. The bottom of the flip box is equipped with a material guide slant plate with a lower left and a higher right. There are two partition plates arranged in parallel at the bottom of the support box. The partition plate separates the support box into three storage boxes. In the material area, the overturning box is a rectangular box, and a heat-conducting oil jacket is installed on the side wall of the overturning box, and the heat-conducting oil jacket is connected with a heat-conducting oil furnace through a circulating pipeline; The feeder is blocked; the left and right inner walls of the turning box are crossed with several baffle and turning plates; the upper right side of the turning box is provided with an exhaust pipe, which is connected to the air injection pipe on the upper left side of the support box through the air hose; the air hose Pass through the exhaust fan, dust box and drying box on the right side of the turning box from top to bottom.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an anti-blocking grain baffle screening machine. 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

[0003] 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

[0004] 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 feeding and turning effect of materials is poor, which leads to poor dust removal and drying effects of the device
