Intermittent rewind type small reel sprinkling irrigation machine

Abstract

The invention discloses an intermittent rewind type small reel sprinkling irrigation machine. The machine comprises a machine frame, a clamping channel type reel, a sprinkling irrigation device and astepping driving device; the clamping channel type reel is provided with a clamping channel in a circumferential direction; the stepping driving device includes a direct current motor, a gearbox, an eccentric swing mechanism, an upper caliper, a lower caliper and an electronic control mechanism; the upper caliper and the lower caliper are clamped on the clamping channel in a cooperation mode. Theintermittent rewind type small reel sprinkling irritation machine adopts the direct current motor to drive the eccentric swing mechanism to achieve eccentric swing, thereby driving the upper caliper to move up and down to intermittently engage the clamping channel of the clamping channel type reel to achieve automatic recycle of a sprinkling irrigation PE pipe by driving the clamping channel typereel to intermittently rewind, during the intermittent rewind process of the clamping channel type reel, the lower caliper can prevent the reversal of the clamping channel reel, the whole machine is mobile and flexible, purposes of saving water resources and reducing working quantities are achieved, simultaneously uniform sprinkling irrigation can be achieved, and the machine is especially suitable for the sprinkling irrigation in greening places such parks, botanical gardens and the like.

Description

technical field [0001] The invention relates to a small reel sprinkler irrigation machine, in particular to an intermittent rewind small 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 position of the wate...

AI Technical Summary

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.
