Spray irrigation device for greenhouse

Abstract

The invention discloses a spray irrigation device for a greenhouse, which comprises a span transfer device and a lifting device, wherein the span transfer device comprises longitudinal rails, transverse rails, a span transfer trolley and a spray irrigation trolley; the span transfer trolley moves along the transverse rails; centring rail are hung below the span transfer trolley; one centring rail is internally provided with a centring mechanism; the spray irrigation trolley moves along the centring rails; the lifting device is hung below the centring rails; in the lifting device, an upper movable frame is connected the upside of a parallelogram telescopic frame; a lower movable frame is connected with the underneath of the parallelogram telescopic frame; a water pipe support rod is located below the lower movable frame; at least one group of spray heads is arranged on the water pipe support rod; each group of spray heads comprises vertical spray heads sprinkling downwards; and a first spray head and a second spray head sprinkling to the two sides are arranged on the two sides of each vertical spray head respectively. The spray irrigation device adopting the structure can realize dead-zone-free spray irrigation, is high in working efficiency, and has good spray irrigation, insecticide spraying and insect killing effects.

Description

technical field [0001] The invention relates to a sprinkler irrigation device, in particular to a sprinkler irrigation device used in a greenhouse. Background technique [0002] In agricultural production, irrigation is an indispensable agricultural operation. With the development of agriculture, the application of greenhouses is becoming more and more extensive. The current domestic greenhouses are generally equipped with several spans, especially steel structure greenhouses. , There are several columns between the spans to support the greenhouse to strengthen the structural strength of the greenhouse. Traditionally, manual sprinkler irrigation or sprinkler irrigation machines that can walk on land are mostly used to irrigate plants in greenhouses. However, with the development of agricultural automation, manual sprinkler irrigation and land-based sprinkler irrigation machines have gradually been replaced by suspended sprinkler irrigation devices. Longitudinal rails are se...

Problems solved by technology

[0003] The main disadvantage of the sprinkler irrigation device with the above structure is that it can only realize the automatic sprinkler irrigation function for a single span in the greenhouse, and cannot automatically switch and move between multiple spans. When the plants in the plant are sprinkled, some plants will not be irrigated, there are dead spots, and the work efficiency is low, and the operation is cumbersome; in addition, the sprinkler range of the sprinkler will become smaller as the plants grow taller, which will cause some plants not to be irrigated. Sufficient water affects the growth of plants; some sprinkler irrigation devices with spraying function, the nozzles are sprayed from top to bottom, the medicine can only be sprayed on the leaf surface, and the medicine can not be sprayed on the back of the leaf, which can only kill the plants Pests on the leaves, it is difficult to kill the pests on the back of the leaves, and the effect of spraying pesticides is not good
