Large-area quantitative irrigation system

Abstract

The invention relates to the technical field of irrigation equipment, especially a large-area quantitative irrigation system, including a water storage tank. A water pump is arranged on the left side of the water storage tank. A water inlet pipe is connected, and the right end of the water inlet pipe communicates with the water storage tank, and the lower end of the right side of the water storage tank is fixedly connected with a connecting pipe, and a flow control device is provided on the connecting pipe, and the connecting pipe is fixedly connected There is a filtering device, the right end of the water delivery pipe is fixedly connected with a shunt pipe, the shunt pipe is fixedly connected with multiple delivery pipes, and the left end of the delivery pipe is provided with a flow control device, and the delivery pipe is connected with multiple streets, and the joints The other end is connected with a vegetable irrigation device. The invention can control the water output speed. At the same time, the combination of the flow control device and the delivery pipe can be used for local irrigation or large-area irrigation. Reasonable control of water volume can avoid waste of water resources and is worth popularizing.

Description

Technical field [0001] The invention relates to the technical field of irrigation equipment, in particular to a large area quantitative irrigation system. Background technique [0002] Irrigation refers to technical measures to replenish the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, sufficient water must be supplied to the crops. Under natural conditions, it is often not satisfied due to insufficient rainfall or uneven distribution Crops require water, so they must be irrigated artificially to make up for the lack of natural rainfall. Therefore, the demand for irrigation equipment is increasing. [0003] At present, most of the vegetables in the vegetable garden are irrigated by ditches and flood irrigation. This method not only competes for the surface water source, but also causes the groundwater level to drop and the ground subsidence, which is subject to various conditions. , Irrigation is prone to malfunction when ...

[0002] Irrigation refers to the technical measures to supplement the water required by the crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Crops require water, so they must be irrigated artificially to make up for the lack of natural rainfall. Therefore, the demand for irrigation equipment is increasing

[0003] At present, when irrigating the vegetables in the vegetable garden, ditches are mostly used to divert water and flood the ground with flood irrigation. This method not only competes for surface water sources, but also causes groundwater levels to drop and land subsidence, which is limited by various conditions. In the event of a sudden water shortage, irrigation is prone to malfunction. At the same time, the flood irrigation method is likely to cause soil salinization in areas with large evaporation, and excessive irrigation will cause pesticide and chemical fertilizer pollution caused by agricultural wastewater, which is inefficient. And the irrigation is uneven. Therefore, a large-area quantitative irrigation system is proposed to solve the above problems.
