As a Seed Cleaner and Grader Manufacturer, share with you.

There are three types of grain screening machines: one is a fan plus a double-deck vibrating screen cleaning mechanism; the other is a fan plus a double-cylinder cleaning mechanism; the third is a cyclone airflow sorting mechanism.

Seed Cleaner and Grader

1. The double-layer vibrating screen and fan-type grain cleaning mechanism has the characteristics of simple structure, reliable work and high productivity. It is a kind of cleaning mechanism that is currently used more. However, it also has large vibration, poor screening and productivity. Improve restrictions and other issues.

2. The double-cylinder screen type impurity removal mechanism is a relatively new type of impurity removal mechanism, which has the advantages of relatively simple structure, no vibration, and low operating noise. In recent years, in order to improve the performance of the cylindrical screen, scholars from various countries have proposed and studied some improved devices, such as changing the cross-sectional shape of the screen cylinder or adding auxiliary components to the cylindrical screen. Although many achievements have been made in these tasks, they have not yet fully met the production requirements.

3. The cyclone air sorting mechanism is a screenless air separation device. Compared with the traditional air screen type impurity removal device, its structure is greatly simplified, basically no fault, low power consumption, and very reliable operation. However, because the technology is not yet mature, it has not been widely used in harvesting machinery.

As far as the combine harvester currently on the market is concerned, due to the mature technology of the fan and double-layer vibrating screen grain removal mechanism and convenient maintenance, although there are some problems, these problems are not insurmountable. Therefore, most products use traditional fans. The structure with double-layer vibrating screen, a small part of it uses a fan and a cylindrical screen structure, and basically does not use a cyclone air flow cleaning mechanism.
