Tree water distribution type movable irrigation system

Abstract

The invention relates to a tree water distribution type movable irrigation system. The system is characterized by including a water storage car, a water distribution gun and an irrigation bag; the water storage car is provided with a water inlet and a water outlet; the water distribution gun comprises a gun body, the gun body is provided with a water inlet pipe and a water outlet pipe, and the water inlet pipe is connected with the water outlet through a pipeline; the irrigation bag comprises an embrace type water bag body fixed to the trunk above soil, the upper portion of the water bag body is provided with a water injection hole, and the water injection hole is connected with the water outlet pipe through a pipeline. A piston block connected with a start rod is arranged in a piston cavity, an air inlet cavity is internally provided with an airtight membrane which is connected with a slide way through a conical plug, the slide way is rotationally connected with the start rod through a support, and the piston block can be controlled to achieve automatic control of water injection amount through coordinated changes of the water amount in subsequent water requiring devices and the air pressure in the air inlet cavity. The system can be powered on automatically and is high in water utilization rate, and the water injection amount can be automatically controlled.

Description

technical field [0001] The invention relates to a tree water distribution type mobile irrigation system, which belongs to the technical field of forestry irrigation. Background technique [0002] my country's forestry irrigation area is very large. According to the results of the eighth national continuous forest inventory: the national forestry land area is 3.44hm 2 , with a forest area of ​​208 million hm 2 , the forest coverage rate is 21.6%, and the forest volume is 151.37hm 2 . At present, my country's forest irrigation mainly adopts agricultural irrigation methods such as furrow irrigation, border irrigation and tree tray irrigation, but the utilization rate of the above-mentioned irrigation methods for modern water-saving irrigation systems is relatively low, and the system mainly uses agricultural irrigation methods. It is neither practical nor economical for irrigation areas. Its main disadvantages are: 1. Due to the shortage of water resources such as Tibet and ...

Problems solved by technology

At present, my country's forest irrigation mainly adopts agricultural irrigation methods such as furrow irrigation, border irrigation and tree tray irrigation, but the utilization rate of the above-mentioned irrigation methods for modern water-saving irrigation systems is relatively low, and the system mainly uses agricultural irrigation methods. Neither practical nor economical for irrigated areas

Its main disadvantages are: 1. Due to the shortage of water resources such as Tibet and the relatively poor soil water storage and water retention conditions in Northwest China, the trees themselves have a certain degree of drought resistance, so the irrigation guarantee rate of trees and the lower limit of soil moisture control can be lower. However, the irrigation cycle required by trees is relatively long, and the existing fixed irrigation system is in a state of non-operation most of the time, and its economic benefits will be greatly reduced

2. Due to the large area and irregular distribution of forest trees, the cost of using farmland irrigation system is obviously too high

Moreover, forest tree irrigation usually requires high irrigation within 3-5 years after planting. After that, the water provided by precipitation can basically ensure the normal growth of forest trees. Therefore, there is an obvious waste of resources in the use of conventional farmland water-saving irrigation system backbone pipes.

3. Since most of the forest irrigation areas are power-deficient areas and severe desertification areas, such as Tibet and other northwestern regions lack power resources, how to maintain the normal operation of fixed systems is also a big problem
