Drip irrigation dripper capable of discharging water stably

Abstract

The invention discloses a drip irrigation dripper capable of discharging water stably. The drip irrigation dripper capable of discharging the water stably is characterized in that an end cap is arranged at one end of a body, a piston is connected to the inner part of the body in a sliding mode, a supporting column is connected to one side of the piston, a first spring is connected to the other side of the piston, and the other end of the first spring is connected with the end cap; a spacer sleeve is arranged on one side in the body, the outer wall of the spacer sleeve is attached to the inner wall of the body, a plurality of connecting rods are arranged at one end of the spacer sleeve, and one end of each connecting rod is connected with the supporting column; a plurality of through water dripping holes are formed in the side wall of the body, the spacer sleeve is located on one side of the water dripping holes, a connector is arranged at one end of the body, a water inlet pipe is connected to one side of the connector, and one end of the water inlet pipe is connected with a capillary pipe. According to the drip irrigation dripper capable of discharging the water stably, the piston is arranged in the body, the spacer sleeve is arranged on one side of the piston, the multiple water dripping holes are formed in the side wall of the body, and the first spring is arranged at one end of the piston; when the water pressure changes, the piston moves up and down under the action of the pressure of the water and the elastic force of the first spring, so that the number of the water dripping holes for discharging the water is controlled, and the water outlet stability of the dripper is ensured.

Description

technical field [0001] The invention belongs to the technical field of drip irrigation drippers, in particular to a drip irrigation dripper with stable water output. Background technique [0002] Drip irrigation is an irrigation method that drips the water and nutrients needed by the crops evenly and slowly into the soil in the root zone of the crops through the piping system and the dripper installed on the capillary according to the water requirements of the crops. Drip irrigation does not damage the soil structure, and the water, fertilizer, air, and heat inside the soil are always kept in a good condition suitable for crop growth. The evaporation loss is small, there is no ground runoff, and there is almost no deep leakage. It is a water-saving irrigation method. The main feature of drip irrigation is that the amount of irrigation water is small, and the flow rate of the emitter is 2-12 liters per hour. Therefore, the duration of one irrigation is longer and the cycle of...

AI Technical Summary

Problems solved by technology

The dripping speed of the existing drip irrigation emitter is affected by the water pressure in the capillary. When the water pressure in the tube is high, the dripping speed is fast, which is easy to cause waste of water or fertilizer. When the water pressure in the tube is low, the dripping speed is very slow, or even impossible. drip out, and when the water pressure in the capillary is not constant, for a long-distance drip irrigation system, the dripping speed of the dripper at the end of the capillary is greatly affected by the water pressure. situation, resulting in uneven drip irrigation
