Focus on U-bolts
The core application scenarios of U-bolts in agricultural machinery
2026-02-05
The plow body is fixed to the plow frame.
In tillage machinery, the plow body is connected to the plow beam via U-shaped screws. For example, the five-furrow plow and the lightweight seven-furrow plow use a combination of straight bolts and U-shaped screws for secure fastening, ensuring that the plow body remains stable and does not loosen during cultivation.
The design of part of the plow body features an L-shaped shallow groove secured by two U-shaped screws, enabling precise positioning and adapting to the tillage requirements under various soil conditions.
Depth-limiting wheel installation
The depth-limiting wheel is used to control the tillage depth. Its components—including the wheel rim, wheel hub connector, and inner sleeve— are secured to the longitudinal beams of the plow frame by U-shaped screws.
The U-shaped screw’s open design allows for quick adjustment of the depth-limiting wheel height, making it adaptable to the planting requirements of different crops.
Round plow blade fixed
The rotary plow blade consists of a blade disc, a blade holder, and other components. It is fixed to the longitudinal beam of the plow frame via a blade post bracket and U-shaped screws.
The adjustable position of the mobile knife holder allows you to optimize the front-to-back distance of the rotary tiller blades, thereby enhancing soil-crushing performance. The flexibility of the U-shaped screw is crucial in this application.
Dam-forming unit assembly connection
In the paddy-field ridge-building machine, the ridge-building plow is secured to the mounting bracket by means of locking screws, and the mounting bracket is then connected to the machine frame via U-shaped screws.
The vibration-resistant properties of the U-shaped screw ensure that the ridge-forming plow remains stable during soil cultivation, producing neatly formed ridges.
Livestock equipment fixed
U-shaped screws specially designed for livestock machinery such as cattle stalls and milking machines are made from galvanized or stainless steel, making them suitable for humid environments and resistant to corrosion.
For example, the U-shaped screws specifically designed for cattle lying-down positions are secured to the bed frame via pressure plates, ensuring that the equipment remains stable even when the livestock is moving.
