TECHNICAL FIELD
[0001] The utility model relates to agricultural sprinkling equipment technical field, concretely relates to a center support shaft formula sprinkling machine center tower. BACKGROUND
[0002] In modern agricultural irrigation systems, center support shaft formula sprinkling machines (also known as circular sprinkling machines) are widely used due to their efficient and uniform irrigation effects. These sprinkling systems typically consist of a center tower, support arms, sprinkler heads, and other components. The center tower rotates to drive the support arms and sprinkler heads along a circular trajectory, achieving omnidirectional irrigation of farmland. However, in practical applications, center support shaft formula sprinkling machines face a pressing problem - line entanglement.
[0003] In traditional designs, various lines required by the center tower and its associated equipment (such as control systems, power supply lines, signal transmission lines, etc.) are often directly exposed or simply fixed to the external structure of the sprinkling machine. As the center tower rotates, these lines are prone to entangling with each other or rubbing against mechanical components, which not only may cause line damage, signal interruption, or power transmission failure, but also may affect the normal operation of the sprinkling machine, reducing operational efficiency and stability. In addition, complex line layouts increase the difficulty and cost of equipment maintenance, which is not conducive to the long-term stable operation of the equipment.
[0004] To solve the above problems, various methods have been tried in the industry, such as using sliding rings or rotary joints to guide the rotation of the lines with the center tower. However, these solutions often have complex structures, high costs, and certain reliability issues in practical applications. Therefore, it is particularly important to develop a new center support shaft formula sprinkling machine center tower design that can effectively avoid line entanglement while maintaining a simple structure and stable operation.

The water supply pipe assembly 3 includes a vertically installed fixed pipe 6, the upper part of which is fixed to the tower 2 by tie rods. A rotating joint 7 is provided at the upper part of the fixed pipe 6, a collector ring 8 is provided at the upper part of the rotating joint 7, and a sealing gasket 9 is provided at the connection between the lower part and the fixed pipe 6. A conduit 10 for use with the collector ring 8 is provided inside the fixed pipe 6. The design of the rotating elbow 7 enables water supply while the truss rotates. At the same time, the design of the conduit 10 allows the wire to be threaded through the pipe and connected to the collector ring 8, ensuring that the wire will not get tangled in the fixed pipe 6 or the rotating joint 7 when the rotating joint 7 rotates, thus preventing damage to the equipment. This improves the operational stability of the equipment and eliminates the need to prepare extra pipelines for distribution on the tower 2, making the overall equipment structure simpler.
