A flow blocking device for water outlet pipes in farmland irrigation

Abstract

The invention discloses a flow blocking device for a water outlet pipe in farm irrigation and relates to the field of farm irrigation devices. According to the device, a supporting rack is fixedly arranged on the water outlet pipe; the supporting rack is connected with a flow blocking plate through a first elastic mechanism and a second elastic mechanism; the water outlet pipe is rotatably connected with the supporting rack through a connection rod mechanism; a first supporting connection plate is vertically fixed to the upper side of the water outlet pipe; a second supporting connection plate is mutually and vertically connected with the first supporting connection plate; a climbing connection plate is connected to the water outlet pipe through an annular opening in a contact mode; the climbing connection plate is vertically connected with a horizontal supporting plate; a first baffle is vertically connected to the other side of the horizontal supporting plate; a second baffle is aslant connected to the other side of the first baffle; a third baffle is aslant connected to the other side of the second baffle. According to the flow blocking device for the water outlet pipe in farm irrigation, the flow blocking plate is arranged on the water outlet pipe, so that in the irrigation process of crops, flowing water in the water outlet pipe is blocked by the flow blocking plate firstly, the impact force of the flowing water is greatly lowered, and the normal growth of the crops is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of farmland irrigation devices, in particular to a flow blocking device for water outlet pipes in farmland irrigation. Background technique [0002] Technical measures for replenishing 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 or uneven distribution of precipitation, it cannot meet the water requirements of crops. Therefore, the ground must be irrigated to make up for the lack of natural precipitation. Irrigation means watering 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 characteristics of the water required by the plant, the growth stage, the climate, and the soil conditions. It should be timely, appropriate, and rational. The types mai...

AI Technical Summary

Problems solved by technology

[0003] In the process of irrigating crops, the impact force of the flowing water in the outlet pipe is large, and there are often phenomena such as the crop seedlings near the outlet pipe being washed down or the roots of the crops being washed down, etc., which will affect the normal growth of the crops and reduce the quality of the crops. Therefore, improving the impact force of the flowing water at the outlet pipe is an important measure to ensure the normal growth of crops
