Middle-through type electric farm windmill

Abstract

The invention relates to a middle-through type electric farm windmill, which comprises a fan, a wind-force adjusting knob, a feed hopper, a feed control board, a bellows, a residue outlet, an immature-product discharge hopper, an immature-product outlet, a certified-product discharge hopper, a certified-product outlet and a rack. The middle-through type electric farm windmill is characterized in that the lower part of the bellows is connected with the rack, and the fan is arranged at the left end of the bellows; the wind-force adjusting knob is connected onto the fan, and the right end of the bellows is connected with the residue outlet; the feed hopper is arranged in the middle of the upper surface of the bellows, and the lower end of the feed hopper is connected with the feed control board; the lower surface of the bellows positioned below the feed hopper is connected with the certified-product discharge hopper, and the lower surface of the bellows close to the certified-product discharge hopper is also connected with the immature-product discharge hopper; the certified-product outlet and the immature-product outlet are respectively formed in the certified-product discharge hopper and the immature-product discharge hopper. The middle-through type electric farm windmill has the advantages of simplifying the structure, increasing the mechanical efficiency, reducing the occupied site, saving labor force and being safe and practical. The structure is more reasonable and compact, the screening efficiency and the rate of finished products are increased, and the operation and the use are convenient.

Description

technical field [0001] The invention relates to a Zhongtong type electric agricultural windmill. Background technique [0002] At present, the windmills used in rural areas to select grains such as rice and wheat have been gradually replaced by electric ones, and the problem of labor-intensive work in the past has been solved. However, both manual windmills and electric windmills currently used are windmills with one end open and the other closed. These windmills have structures such as bellows and blades, which not only occupy the volume of the windmill, but also increase the load on the windmill, making it difficult to move. . Simultaneously, because the electric windmill that uses now is that motor is directly contained on the windmill, neither is easy to repair, maintain, and is equally heavy and inconvenient to operate. Therefore existing windmill is not convenient enough yet, needs improvement. In addition, because the shape design of the genuine product hopper and ...

AI Technical Summary

Problems solved by technology

[0002] At present, the windmills used in rural areas to select grains such as rice and wheat have gradually replaced manual ones by electric ones, and the problem of labor-intensive work in the past has been solved.

However, both manual windmills and electric windmills currently used are windmills with one end open and the other closed. These windmills have structures such as bellows and blades, which not only occupy the volume of the windmill, but also increase the load on the windmill, making it difficult to move.

At the same time, since the electric windmills currently in use are directly mounted on the motors, it is not easy to repair and maintain, and it is also very heavy and inconvenient to operate.

Therefore existing windmill is not convenient enough, needs improvement

In addition, there are also great defects in the shape design of the genuine product discharge hopper and the grain product discharge hopper in the current bellows, which makes the authenticity rate of the crops screened by gravity and wind force very low, and the screening efficiency is also very low, which cannot meet the requirements of different crops. The screening of crops can only be used by a single machine
