Description

Technical Field

[0001] The utility model relates to the technical field of rotary screens, in particular to a horizontal rotary screen for grain and oil processing. Background Technique

[0002] The rotary screen, also known as the cylindrical screen, is different from the general cylindrical screen. Generally, the screen of the cylindrical screen is single-layer, while the rotary screen is a special screen for compound fertilizers, and the horizontal rotary screen is a grain cleaning equipment that relies on the inertial centrifugal force of the counterweight to realize the horizontal rotation of the screen body. For different materials, the corresponding screen sheets, screen surface inclination angles, motor speeds and the mass of the rotating body can be used to achieve the best comprehensive screening effect. It is suitable for the screening and grading of solid materials and is widely used in the cleaning of grains such as wheat and rice. However, there are still some problems and defects in the use of traditional rotary screens.

[0012] Preferably, limiting sliders are connected to both bottoms of the two sides of the lifting cylinder. Limiting sliding grooves matched with the limiting sliders are connected to both sides inside the support cylinder. The limiting sliders sliding along the limiting sliding grooves can limit and assist the lifting cylinder to move up and down linearly along the screw rod.
