Environmental-friendly circulating drip-irrigation device for trees

Abstract

The invention provides an environmental-friendly circulating drip-irrigation device for trees. An outer barrel is of a cylindrical structure; drip-irrigation holes are formed in the outer barrel; an end cover is arranged on the upper end of the outer barrel; a filter drum is assembled in the outer barrel; a one-way solenoid valve is arranged on the upper end of the end cover, and is assembled with a water pipe; a light sensor is arranged on the upper end position of the end cover; a humidity sensor is arranged on the lower end position of the side face of the outer barrel. The trees are irrigated through adding the drip-irrigation holes on the outer barrel; with the design, the water-saving efficiency is effectively improved; the filter drum located in the outer barrel plays a role in filtering water, so that impurities in water are prevented from blocking the drip-irrigation holes, and thus the cost required for maintaining the environmental-friendly circulating drip-irrigation device is reduced to some extent; in addition, with the design of the light sensor, the detection on external lights is realized; the humidity sensor is used for detecting humidity of the lower end of the outer barrel; the design can conveniently control the one-way solenoid valve to switch on and switch off.

Description

technical field [0001] The invention is an environment-friendly circular drip irrigation device for trees, which belongs to the field of agricultural equipment. Background technique [0002] In the prior art, drought and water shortage is a worldwide problem. The arable and semi-arid areas of the world account for about 43% of the total arable land, and about 80 countries and 40% of the population are facing the problem of water shortage. my country is one of the 13 countries with severe water shortage in the world, and also one of the countries with serious shortage of agricultural water resources. The shortage of agricultural water resources has become a factor restricting agricultural development for a long time after arable land resources. Under the condition of limited arable land and water resources, it is necessary to rely on science and technology to greatly increase land productivity and accelerate the development of water-saving agriculture. At present, drip irrig...

AI Technical Summary

Problems solved by technology

At present, drip irrigation uses a combination of water storage bags, siphons and drip irrigation heads, which effectively solve the problem of water storage, uniform irrigation, fertilizer and pesticide application, but these drip irrigation devices are mainly installed on the surface, and the water mainly moves to the underground root system through the surface. , it takes a certain amount of time to penetrate the soil to reach the root system of the tree. After irrigation, the soil water content decreases from the surface to the deep soil layer in turn, and the evaporation on the surface is large, the consumption is large, and the water resource utilization efficiency is low. Therefore, an environmental protection cycle drip irrigation device for trees is needed. solve the above problems
