Power transmission system of reel sprinkling irrigation machine and working method thereof

Abstract

The invention discloses a power transmission system of a reel sprinkling irrigation machine and a working method thereof. The power transmission system comprises a controller. The output end of the controller is connected with the input end of a driver. The output end of the driver is connected with the input end of a stepping motor. An output shaft of the stepping motor is connected with an input shaft of a speed reducer. An output shaft of the speed reducer is connected with an inner hole in one end of an electromagnetic clutch. A flange at the other end of the electromagnetic clutch is connected with a minor sprocket. The minor sprocket is connected with a large chain ring through a chain. The large chain ring is fixed to a reel. Before an irrigation cart is dragged to a work place, the electromagnetic clutch is powered off to be opened; when a PE pipe and the irrigation cart are recycled, the electromagnetic clutch is powered on to be closed. A controller produces a pulse signal, and the stepping motor is driven by the driver to run, the stepping motor drives the large chain ring through a transmission structure to rotate, and the large chain ring drives the reel to rotate to recycle the PE pipe and the irrigation cart. According to the power transmission system, the speed can be accurately adjusted, the energy consumption is reduced, the number of adopted mechanical structures is reduced, the cost is reduced, the reliability is high, and the automation degree is high.

Description

technical field [0001] The invention relates to the field of farmland water-saving irrigation, in particular to a power transmission system and a working method of a reel sprinkler irrigation machine suitable for farmland water-saving irrigation. Background technique [0002] With the rapid development of modern agricultural technology, the reel sprinkler has become a widely used farmland irrigation and drainage equipment. The existing reel sprinkler irrigation machine mainly uses the water pump to generate pressure water to drive the water turbine to generate power, and then drives the reel to run through the transmission device, pulls the PE pipe to wind on the winch, and pulls the sprinkler car to move and spray automatically. [0003] The water turbine currently used causes a large pressure drop, high energy consumption, and low efficiency, so a high-power water pump needs to be selected as the power source; at the same time, the existing reel sprinkler irrigation machin...

Problems solved by technology

[0003] The water turbine currently used causes a large pressure drop, high energy consumption, and low efficiency, so a high-power water pump needs to be selected as the power source; at the same time, the existing reel sprinkler irrigation machine speed control system is a set of connecting rod mechanism, through the connecting rod mechanism The speed of the water turbine is controlled by controlling the opening of the tongue of the water turbine. The structure is complex and the control accuracy is low; and the meshing and disconnection of the sliding gears are controlled through the gear release mechanism in the gearbox, and the cutting and closing of the power is controlled, which is convenient for the sprinkler truck. release and recovery, but this makes the structure of the gearbox complex, high in cost, and large in overall size; although the existing sprinkler can use a set of linkage mechanisms to achieve speed regulation and off-gear, the overall structure is complex, and it will affect the action of the mechanism after long-term use accuracy, poor reliability
