According to the technical scheme provided by the invention, the dripper can be automatically prevented from being blocked, and operation stability of the device is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, in particular to an irrigation device for agricultural planting. Background technique [0002] Irrigation is the technical measure of replenishing the soil with the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. Irrigation, i.e. irrigating the land with water. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions, and should be timely, appropriate, and rational ir...

AI Technical Summary

Problems solved by technology

The irrigation method of surface irrigation often consumes a lot of water and has low water utilization, which is a very unreasonable agricultural irrigation method.

Ordinary sprinkler irrigation technology is a relatively common irrigation method in China's agricultural production, but the water utilization efficiency of ordinary sprinkler irrigation technology is not high; modern agricultural micro-irrigation is usually drip irrigation, which has better water-saving performance and higher water utilization than traditional irrigation modes. High, but the cost of drip irrigation is high, and it is easy to be blocked when drip irrigation with water and fertilizer integration is carried out, and the non-water-soluble fertilizer of medicine irrigation cannot be irrigated through drip irrigation equipment, and another fertilization system needs to be added

[0003] Existing irrigation equipment can only be used for drip irrigation or sprinkler irrigation, and the irrigation method is single. The use of sprinkler irrigation equipment will lead to waste of water resources; the use of drip irrigation equipment requires additional fertilization systems, and frequent manual cleaning of drippers, resulting in time-consuming and laborious
