Agricultural blowing and drying and screening machine

Abstract

The invention discloses an agricultural blower drying and screening machine, which comprises a heating box, an equipment box and a collection chamber; a fan and a heating box are installed at the bottom of the heating box, and a horizontal arc-shaped Stencil; a horizontal receiving device is installed in the heating box, and the receiving device includes a plate body, a guide seat, a screen, a feeding port and a guide groove, and guide seats are fixed on both sides of the plate body; An upper rack and a lower rack are respectively installed on the top and the bottom of the push-pull cylinder, and half gears are installed in the push-pull cylinder. The invention uses the hot air blowing upwards to quickly dry the grains. The dried grains are blown upwards under the action of the wind and fall on the receiving device. The grain is put down and falls into the receiving hopper below, discharged and collected, and the fully dried grain is separated from the arc-shaped mesh plate under the wind screening, and the screening is accurate.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural blast drying and screening machine. Background technique [0002] With the deepening of the reform of my country's grain circulation system, the full opening of the grain purchase market, and the diversification of grain purchase entities, in recent years some farmers, grain depots, and grain processing enterprises have equipped themselves with grain dryers, so that they can purchase high-moisture grains in a timely manner. Drying and storage, the use of these dryers has greatly alleviated the problem that grains with high moisture content cannot be purchased and stored in time, reduced the loss of grain mildew, and improved the economic benefits of farmers and enterprises. However, the performance and quality of the dryers currently on the market still cannot meet the requirements for grain drying. Therefore, the problem of how to more effectively dry and store grain has...

AI Technical Summary

Problems solved by technology

[0003] During the grain drying process, due to the large amount of grain, the fully dried grain is still being dried, and it is taken out only after all the grain is dried, which increases the energy consumption of the equipment, and also makes the grain excessively dry, affecting the food consumption. It is not conducive to the sale of grain and reduces the income of farmers. Therefore, it is necessary to improve the existing dryer
