Control method of small reel spray irrigation machine for greening spray irrigation

Abstract

The invention discloses a control method of a small reel spray irrigation machine for greening spray irrigation. The small reel spray irrigation machine for greening spray irrigation comprises a machine frame, a clamping way type reel, a spray irrigation device and a stepping driving device. A clamping way in the circumferential direction is arranged on the clamping way type reel. The stepping driving device comprises a reciprocating lifting cylinder, an upper clamping claw, a lower clamping claw, an electromagnetic reversing valve and an electric control mechanism. The upper clamping claw andthe lower clamping claw are matched and clamped on the clamping way. According to the control method of the small reel spray irrigation machine for greening spray irrigation, pressure water passes through an electromagnetic reversing valve to drive a lifting cylinder so as to make a piston rod periodically rise and fall, then the upper clamping claw is driven to move up and down so as to be intermittently meshed with the clamping way of the clamping way type reel, the clamping way type reel is driven to intermittently reel so as to automatically collect a spray irrigation PE pipe, the lower clamping claw can prevent the clamping way type reel from rotating backward in the intermittent reeling process of the clamping way type reel, water resources can be saved, the engineering amount is reduced, uniform spray irrigation can be achieved, and the small reel spray irrigation machine is particularly suitable for spray irrigation of greening places such as parks and planting gardens.

Description

technical field [0001] The invention relates to a control method of a reel sprinkler irrigation machine, in particular to a control method of a small-scale reel sprinkler irrigation machine suitable for small-scale sprinkler irrigation in green places such as parks and botanical gardens, and belongs to the technical field of sprinkler irrigation equipment. Background technique [0002] Sprinkler irrigation is an irrigation method that uses special equipment such as nozzles to spray pressurized water into the air to form water droplets that fall to the ground and crop surfaces. [0003] Such as parks, botanical gardens and other green places can not only be used for recreation, but also have the function of protecting and improving the environment, which has played a positive role in promoting urban greening and environmental protection. Existing sprinkling irrigation of green places mostly uses nozzles for irrigation, that is, the nozzles are fixed and installed on the set p...

Problems solved by technology

[0004] This traditional sprinkler irrigation method requires pre-embedded water delivery pipe network during the construction of green spaces, so not only is the project volume huge, but also the pre-buried water delivery pipe network arranged below the ground is not easy to maintain, and it is difficult to troubleshoot in case of failure or water leakage ; and factors such as the topography, ground slope, and vegetation planting direction of the greening site will affect the layout of the water delivery pipe network, which will invisibly increase the amount of engineering; due to the use of fixed-point sprinkler irrigation, the coverage area of ​​​​a single sprinkler head is limited. Therefore, it is necessary to set a suitable nozzle combination spacing to avoid the dead angle of sprinkler irrigation; in addition, since the sprinkler water sprayed from the sprinkler is affected by its own gravity, the horizontal distribution of the soil during the sprinkler irrigation process will gradually decrease from the center of the sprinkler to the outside. The cross-section is conical. Although the proper nozzle combination spacing can avoid the dead angle of irrigation, it will still cause uneven irrigation and waste of water resources.
