Self-locking device for spray head trolley suspending and descending

Abstract

The invention discloses a self-locking device for spray head trolley suspending and descending. The self-locking device comprises supporting frames, an electric cabinet, triangular plates, motors, threaded self-locking device bodies, a beam and a pressure sensor. The pressure sensor is arranged on the beam, the supporting frames are arranged at the two ends of the beam, each supporting frame comprises a side support, an inclined support and a front support, the two ends of the beam are connected with the front supports, the electric cabinet is arranged on one side support, the side supports are connected with one ends of the inclined supports, the other ends of the inclined supports are hinged to one ends of the front supports, the other ends of the front supports are hinged to one ends of the threaded self-locking device bodies, the other ends of the threaded self-locking device bodies are connected with the motors, the motors are rotationally connected with the triangular plates, the triangular plates are connected with the inclined supports, and the electric cabinet is connected with the motors and the pressure sensor through wires. The spray head trolley can be safely and reliably recovered, suspended and descended and can be transferred synchronously with a reel.

Description

technical field [0001] The invention relates to a reel-type sprinkler irrigation machine, in particular to a self-locking device for hanging and dropping a sprinkler cart, which is used for safe and reliable recovery of the suspended and dropped sprinkler cart, and facilitates the synchronous transfer of the sprinkler cart and the reel. Background technique [0002] With the development of agricultural technology, the reel type sprinkler is widely used in the field of agricultural irrigation because of its excellent spraying performance and the characteristics that the sprinkler truck can be hung on the sprinkler after being recovered and transferred synchronously with it. However, the currently used sprinkling irrigation machine nozzle car suspension device has a fixed recovery suspension angle, and adopts the method of inertial suspension after the recovery nozzle vehicle violently hits the beam, which leads to unreasonable force on the recovery suspension components, which...

AI Technical Summary

Problems solved by technology

However, the currently used sprinkling irrigation machine nozzle car suspension device has a fixed recovery suspension angle, and adopts the method of inertial suspension after the recovery nozzle vehicle violently hits the beam, which leads to unreasonable force on the recovery suspension components, which is likely to cause component damage. The recovery suspension is safe and reliable. The reliability is low, and when the terrain is undulating, the use efficiency of the recovery suspension device is greatly limited, and the process of dropping the sprinkler truck before the start of sprinkler irrigation is labor-intensive, which seriously hinders the promotion and development of sprinkler irrigation machines
