Sprinkler turnplate driven by stepping motor and control method

Abstract

Disclosed are a sprinkler turnplate driven by a stepping motor and a control method. The sprinkler turnplate comprises a pulse signal generator, a drive circuit, the stepping motor, an inner plate and an outer plate. One flange is arranged at the upper end of the inner plate, and the other flange is arranged at the lower end of the outer plate and mounted on the inner plate. Balls capable of moving relatively are arranged between the inner plate and the outer plate. An inner gear ring is fixed on the inner wall of the inner plate, and a gear meshing with the inner gear ring is arranged on the inner side of the inner plate and is directly arranged on an output shaft of the stepping motor. Inner plate pin holes and outer plate pin holes are formed on the corresponding circumferences of the flange at the upper end of the inner plate and the flange at the lower end of the outer plate. The drive circuit controls running of the stepping motor so as to drive a gear mechanism to drive the turnplate to rotate. When the stepping motor drives the turnplate to a position required, input of electric pulse signals to the drive circuit is stopped; by inserting pins to the pin holes on the corresponding circumferences, the turnplate is positioned and locked. The sprinkler turnplate is simple in structure, convenient to operate, high in reliability and labor saving.

Description

technical field [0001] The invention relates to a turntable of a sprinkler irrigation machine driven by a stepping motor and a control method thereof, and is especially suitable for rotating and locking the turntable of a reel type sprinkler irrigation machine. Background technique [0002] With the development of agricultural technology, reel sprinkler irrigation machines are widely used in agricultural production because of their uniform spraying and high efficiency. But in the actual operation of the reel sprinkler irrigation machine at present, the rotation of the turntable of the reel sprinkler irrigation machine is mainly driven by manpower, and it is time-consuming and laborious to rotate it to the required position, which causes inconvenience to agricultural production. Contents of the invention [0003] Technical problem: The purpose of this invention is to overcome the shortcomings of the existing sprinkler irrigation machine turntable drive method, and provide a...
