Control method of eccentric swing stepping rollback reel sprinkler

Abstract

The invention discloses a control method of an eccentric swing stepping rollback reel sprinkler. The eccentric swing stepping rollback reel sprinkler comprises a rack, a clamping channel type reel, asprinkling device and a stepping driving device; the clamping channel type reel is provided with a clamping channel arranged in the circumferential direction; the stepping driving device comprises a water turbine gearbox, an eccentric swing mechanism, an upper clamping caliper and a lower clamping caliper, and the upper caliper and the lower caliper are cooperatively clamped to the clamping channel. By means of the control method of the eccentric swing stepping rollback reel sprinkler, a water turbine is adopted to drive the eccentric swing mechanism to achieve eccentric swing and then drivesthe upper clamping caliper and the lower clamping caliper to be intermittently meshed with then clamping channel of a clamping channel type reel to drive the clamping channel type reel to be intermittently rolled to automatically recycle a sprinkling PE pipe, gardening vegetation is conveniently sprinkled, the using flexibility is high, maintenance is facilitated, on the premise of saving water resources, water in sprinkled soil can be uniformly distributed, uniform irrigation is guaranteed, and the control method is particularly applicable to gardening irrigation.

Description

technical field [0001] The invention relates to a control method of a reel sprinkler irrigation machine, in particular to a control method of an eccentric swing step-rewind type reel sprinkler irrigation machine suitable for garden sprinkler irrigation, and belongs to the technical field of garden sprinkler irrigation equipment. Background technique [0002] Using engineering technology and artistic means in a certain area to create a beautiful natural environment and recreational environment by transforming the terrain (or further building mountains, stacking stones, and water management), planting trees and flowers, building buildings, and arranging garden roads, etc. It is called gardens, and gardens usually include gardens, house gardens, small gardens, gardens, parks, botanical gardens, etc. Gardens are not only used for recreation, but also have the function of protecting and improving the environment, which has played a positive role in urban greening and environmental...

AI Technical Summary

Problems solved by technology

[0005]1. Due to the pre-buried water pipe network during garden construction, not only is the engineering volume huge, but also the water pipe network pre-buried below the ground is not easy to maintain. It is difficult to troubleshoot when there is a fault or water leakage;

[0006]2. Factors such as the shape of the garden plot, the slope of the ground, and the direction of vegetation planting will all affect the layout of the water pipe network, which will invisibly increase the amount of engineering;

[0008]4. Usually, the pressurized pumping station needs to be located in the center of the lot to reduce the amount of pipeline consumption and the head loss of the water pipeline, thereby reducing the investment cost and operating cost, but often As a result, the pressurized pump station that is far away from the water source needs to be additionally pre-buried to install the water delivery pipeline of the pressurized pump station, which is also difficult to maintain;

[0009]5. Since the sprinkler water sprayed from the nozzle is affected by its own gravity, the horizontal distribution in the soil will gradually decrease from the center of the sprinkler to the outside during the sprinkler irrigation process. , The cross-section is a conical structure. Although the proper nozzle combination spacing can avoid the dead angle of irrigation, it will still cause uneven irrigation and waste of water resources.
