Spray irrigation device with spraying range adjusting function

Abstract

The invention discloses a spray irrigation device with a spraying range adjusting function. The spray irrigation device comprises a base, a water tank, a disk, a movable rod and a sliding column, thewater tank is fixed at the top of the base, the disk is rotatably connected on a vertical plate fixed on the right side of the top of the water tank, the sliding column is arranged on the front end surface of the disk, the movable rod is arranged on the front side of the disk, and rollers are symmetrically mounted on two sides of the bottom of the base. When the spray irrigation device works, thedisk drives a spraying pipe to vertically reciprocate through the sliding column, so that a parabola formed by a water stream is changed from near to far and then from far to near, covered spraying is performed in a certain area, spray irrigation uniform is ensured, the rotating radius of the sliding column can be changed by adjusting the position of the sliding column in an adjusting hole, the vertically reciprocating stroke of the spraying pipe is controlled, spraying range is changed, and the spray irrigation device can be flexibly adjusted according to crops of different areas.

Description

technical field [0001] The invention relates to water conservancy irrigation, in particular to a sprinkler irrigation device with adjustable spraying range. Background technique [0002] my country's mountainous area accounts for more than 65% of the country's land area. The mountainous terrain is complex, and the main land for agricultural production is mainly beams, slopes, and platforms. So far, mountainous agricultural production has not yet gotten rid of the situation of relying on the sky, and there are often times of drought, but crops Growth should be supplemented with water in real time and in an appropriate amount to ensure its output. Therefore, when the precipitation is insufficient or unevenly distributed and cannot meet the water requirements of crops, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. [0003] Most of the sprinkler pipes in the existing sprinkler irrigation devices are fixed, and the spray range is sma...

AI Technical Summary

Problems solved by technology

Therefore, when the precipitation is insufficient or unevenly distributed and cannot meet the water requirements of crops, artificial irrigation must be carried out to make up for the lack of natural rainfall.

[0003] Most of the sprinkler pipes in the existing sprinkler irrigation devices are fixed, and the spray range is small, so the crops cannot be irrigated evenly. To solve this problem, some sprinkler irrigation devices design the sprinkler pipes as movable, so that Effectively expand the spraying range, but most of these devices have a disadvantage, that is, they cannot control the spraying coverage, and cannot flexibly adjust for different areas of crops, which will easily cause the marginal crops to be unable to be sprayed or Spray coverage exceeds the area occupied by crops, resulting in waste of water resources
