Problems solved by technology

[0004] The reel type sprinkler generally adopts the water turbine power drive system, which usually mainly includes the chassis, reel, PE pipe, water turbine, gearbox, speed compensation device and sprinkler truck. The turbine shaft is transmitted to the reducer, and after the speed is reduced, the chain drive generates a large torque to drive the winch to rotate, thereby realizing the automatic recovery of the PE pipe. Although the reel sprinkler has high irrigation efficiency and saves water, it is usually During the sprinkling irrigation operation, the PE pipe is gradually rolled back onto the reel. During the sprinkling irrigation operation, the effective diameter of the reel and the frictional resistance between the PE pipe and the ground change, and the angular velocity of the reel also changes. However, the rotation speed of the reel is usually constant, which will inevitably cause the movement speed of the PE pipe to change, which will lead to unsatisfactory sprinkler irrigation effects. In the prior art, a pull rod mechanism installed on a safety winding device is usually used. The automatic speed regulation mechanism composed of traction wire rope and the second valve realizes automatic speed regulation. Specifically, the purpose of automatic speed regulation is achieved by adjusting the opening of the second valve to control the flow of the water turbine through the pull rod mechanism, but the structure is more complicated and purely mechanical. The manufacturing error of the structural rod mechanism and the transmission at all levels will easily lead to inaccurate operation and the inability to accurately control the recovery speed of PE pipes
