Water-saving irrigation device for agricultural greenhouse planting

Abstract

The invention discloses a water-saving irrigation device for agricultural greenhouse planting. The water-saving irrigation device comprises a movable irrigation frame, two irrigation connecting frames, an irrigation spray pipe, a connecting assembly and a rotating roller shaft, wherein the two irrigation connecting frames are mutually symmetrical about the axis of the movable irrigation frame; andthe irrigation spray pipe is horizontally fixed between the top ends of the two irrigation connecting frames. The water-saving irrigation device has the advantages that the bottom of the irrigation spray pipe is horizontally connected with the rotating roller shaft through the connecting assembly; the surface of the rotating roller shaft is connected with a turning tooth frame; during irrigationoperation, the rotating roller shaft can be driven by a driving motor to rotate; the rotating roller shaft drives the turning tooth frame to push aside leaves of plants; then, water spraying irrigation is performed through an irrigation spray head arranged on the irrigation spray pipe, so that the sprayed water can be directly sprayed onto the soil to be absorbed by the soil; the circumstance thata great number of water is attached onto the leaves is avoided; the evaporation loss is reduced; the water quantity required by the single irrigation is reduced; and a purpose of saving water is achieved.

Description

technical field [0001] The invention relates to the technical field of greenhouse planting irrigation devices, in particular to a water-saving irrigation device for agricultural greenhouse planting. Background technique [0002] With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. Greenhouses were originally special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. Currently, greenhouses have been used for potted plants. and cut flower cultivation; fruit tree production is used to cultivate grapes, strawberries, watermelons, melons, peaches and citrus, etc.; forestry production is used for tree seedling cultivation, ornamental tree cultivation, etc. The water-saving irrigation device for agricultural greenhouse planting is a kind of agricultural greenhouse. Equipment for irrigating and watering plants grown in...

AI Technical Summary

Problems solved by technology

[0003] Most of the water-saving irrigation devices used in the market for planting in agricultural greenhouses are to install irrigation nozzles on the movable irrigation racks, and set irrigation nozzles on the irrigation nozzles to realize mobile watering of the plants in the greenhouses, but when watering Because the leaves of the plants are relatively dense, the water for irrigation will adhere to the leaves and then be evaporated, but cannot be absorbed by the soil. It is necessary to increase the amount of water for irrigation to improve the humidity of the soil, which wastes water resources. At the same time, the existing agricultural greenhouses are planted The two mobile rollers on the mobile watering frame of the water-saving irrigation device are mostly fixed structures, which cannot be adjusted, and cannot be used for mobile watering on planting beds of different widths
