Adjustable screw is a mechanical transmission component, usually composed of a screw (lead screw shaft) and a nut. The basic principle is to drive the nut to move axially through the rotation of the screw, achieving linear motion. This design allows the Seedbed to rise or fall as needed, thereby adjusting the height or position of the seedbed.

Screw transmission belongs to spiral transmission, which achieves linear motion through the engagement of nuts and screws, with small transmission errors (usually up to 0.01-0.1mm level), and can accurately control the movement distance of greenhouse equipment.

The greenhouse environment has high humidity and may contain corrosive gases such as pesticide or fertilizer volatilization. The adjustable screw is hot-dip galvanized to enhance rust prevention and corrosion resistance.

The  adjustable screw is widely used in seedbeds and plays a crucial role in adjusting the height of the seedbed.
