An adjustable underground alternate irrigation device

Abstract

The present invention disclosed a adjustable underground alternate irrigation device, including cylindrical, breaking cone, irrigation mechanism, water supply pipes, irrigation operation mechanisms, irrigation direction operation mechanisms.In the body, the water supply parts connect to the irrigation mechanism, and the irrigation operating agency and the irrigation direction operating mechanism connect to the irrigation mechanism; the irrigation mechanism has up and down irrigation machines, the upper and lower irrigation devices have two irrigation directions.Solid water pipe water supply; this device adopts underground alternate irrigation method, there are four irrigation directions, two irrigation directions of the upper irrigation device, and the vertical spacing of the two irrigation directions of the irrigation device can be adjusted.In the adjustment, the sequence of irrigation in the direction of four irrigation can be arranged arbitrarily. Among the four irrigation directions, one irrigation direction of the upper and lower water can be permeable at the same time.

Description

technical field [0001] The invention relates to an adjustable underground alternate irrigation device, which belongs to the technical field of agricultural water-saving irrigation. Background technique [0002] Water is an essential substance for the growth of crops. Agricultural water consumption accounts for 70% of my country's water consumption. However, with the development of industry, the increase in industrial water consumption and the pollution of water bodies have resulted in less and less agricultural water supply. For the sake of social development and stability, especially to solve the food security problem of 1.3 billion people, we urgently need to alleviate the current water shortage by improving the efficiency of agricultural water use and saving irrigation water. [0003] In recent years, the root system zoning alternate irrigation technology proposed by Academician Kang Shaozhong can significantly save irrigation water and play a positive role in promoting th...

Problems solved by technology

[0004] At present, there are many patents related to alternate irrigation, most of which are only for the above-ground part, such as a cantilever-type alternate irrigation system (201310221169.5), a root partition alternate irrigation controller and its irrigation system (201110415816.7), an alternate row irrigation method for fruit trees ( 200810138044.5), an intelligent control method and system for local root zone alternate irrigation of crops (200910085350.1), these patents can achieve the purpose of alternate irrigation of the aboveground part, but due to the surface irrigation, the evaporation loss of the soil surface is more, and the irrigation After the system is deployed, the irrigation distance cannot be adjusted, and the growth of the crop root system is in a dynamic change. When the irrigation system is deployed, the irrigation position cannot always be kept optimal, resulting in low irrigation water utilization efficiency.

Compared with the above-ground alternate irrigation device, due to the blockage of underground emitters, there are fewer related patents related to underground alternate irrigation. (201010229935.9)", although it can be used for subsurface alternate irrigation in the horizontal direction, the system cannot perform subsurface alternate irrigation in the vertical section. The capillary tube and a plurality of infiltrators connected with the capillary tube are composed of many parts in the system, which need to be buried in the ground before use, which takes a lot of work and effort. In particular, this patent does not solve the problem of blockage of the underground sprinkler well. Once the irrigation system If there is a problem, firstly it is difficult to find the location of the problem, and secondly, it is more laborious to maintain. Due to the influence of the layout of the underground pipe network, it is not convenient for the deep loosening of the soil in the root zone of fruit trees and the application of farmyard manure.
