Simple agricultural grain winnowing machine

Abstract

The invention discloses a simple agricultural grain winnowing machine which comprises a winnowing box and a de-dusting drying oven. The simple agricultural grain winnowing machine is characterized in that support legs are symmetrically arranged on left and right sides of the winnowing box; the winnowing box is arranged as a rectangular box; the de-dusting drying oven is arranged on the left side at the upper end of the winnowing box; the de-dusting drying oven is arranged as a cylindrical drum; an electromagnetic heating coil is clamped in a wall of the de-dusting drying oven; the bottom left side of the drying oven is communicated with the winnowing box through a connecting pipe; a blanking pipe is arranged in the middle of the top of the de-dusting drying oven; an adjusting valve is arranged on the blanking pipe; a feeding hopper is arranged at the upper end of the blanking pipe; a material collecting hopper is arranged in the de-dusting drying oven; an edge at the upper end of the material collecting hopper is connected with an inner wall of the winnowing box; a blanking hole is formed in a middle position at the lower end of the material collecting hopper; and a material distributing hopper is arranged above the material collecting hopper. The simple agricultural grain winnowing machine has the advantages of simple and reasonable structure, good winnowing effect, good de-dusting and drying effects, capability of reducing production cost of the device and high practicability.

Description

technical field [0001] The invention relates to a winnowing machine, in particular to a simple agricultural grain winnowing 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

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
