Description

A new type of farmland irrigation device for water conservancy projects

technical field

The utility model relates to the technical field of water conservancy projects, in particular to a new type of farmland irrigation device for water conservancy projects.

Background technique

In agriculture, it is necessary to ensure the normal growth of crops to obtain high and stable yields, and sufficient water must be supplied to the crops. However, due to the influence of the natural environment, often due to insufficient or uneven distribution of precipitation, the water requirements of crops cannot be met; therefore, artificial irrigation of farmland is required. The irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. Traditional surface irrigation includes border irrigation, furrow irrigation, flood irrigation and flood irrigation. The patent document whose publication number is CN213153255U in the prior art provides a farmland irrigation device for a new type of water conservancy project, and the device irrigates the farmland far away from the irrigation device by the water sprayed by the long-distance sprinkler, and the water sprayed by the close-range sprinkler The farmland near the irrigation device is irrigated, so that the farmland in the far and near range of the irrigation device can be evenly irrigated with water. Although the device has many beneficial effects, there are still the following problems: when the nozzle is sprayed for irrigation at a short distance, the lower end of the device is easy to be irrigated. The location of the land is irrigated and soaked, resulting in unstable support, which is not conducive to the irrigation work of the device. In view of this, we propose a new type of farmland irrigation device for water conservancy projects.
