Abstract

A seepage irrigation device belongs to the technical field of watering devices installed underground with perforated pipes. It includes a capillary tube with holes on the pipe wall, and an emitter is connected to the pipe wall. The emitter is an elastic blind pipe, and the blind end of the blind pipe has a normal closed hole. The blind end hole of the blind pipe is a horizontal long hole. The emitter is screwed to the wall hole of the capillary tube through a pipe joint with an external thread at one end. The open end of the blind pipe of the emitter is plugged into the wall hole of the capillary tube through a pipe joint with a small outer and inner large card platform at one end. The wall hole of the capillary tube is connected with a branch pipe, and the open end of the blind pipe of the emitter is sleeved on the outer end of the branch pipe. A speed control device is installed at the water inlet end of the capillary. Using the utility model for seepage irrigation can effectively solve the problem of inner and outer blockage of the emitter and the unbalanced water supply between the capillary tubes; connecting the emitter and the capillary tubes with branch pipes can also greatly reduce the construction cost and save expenses.

Description

an irrigation device

technical field

The utility model belongs to the technical field of watering devices installed underground by using pipes with holes.

Background technique

Water-saving irrigation methods mainly include sprinkler irrigation, drip irrigation, and seepage irrigation. The utilization rate of seepage irrigation water is more than 95%, which is 20% less than drip irrigation and more than 30% less than sprinkler irrigation. The water-saving effect is obvious. Especially when used in a greenhouse, it can effectively reduce the humidity in the greenhouse, reduce the occurrence of crop rot and pests, and improve the quality of crops; increase the room temperature, shorten the maturity period of crops, and increase the yield by more than 30%. Existing seepage irrigation devices structurally include a capillary or a mother pipe, holes are opened on the wall of the capillary or the mother pipe, and the openings are directly filled with water, or wrapped with non-woven fabric outside the pipe, or opened to connect to the water emitter. The water outlets of the existing emitters all have regular openings. Therefore, no matter whether the capillary outer openings are directly filled with water or filled with non-woven fabrics, or the existing emitters are used, it is easy to cause blockage.

Utility model content

The purpose of the utility model is to provide a seepage irrigation device which is not easy to be blocked.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a seepage irrigation device, comprising a capillary tube with holes on the pipe wall, an emitter is installed on the pipe wall, the emitter is a dead pipe with elasticity, and the blind end of the blind pipe There is a normal obturator.

The blind end hole of the blind pipe is a horizontal long hole.

The emitter is screwed to the wall hole of the capillary tube through a pipe joint with an external thread at one end.

The open end of the blind pipe of the emitter is plugged into the wall hole of the capillary tube through a pipe joint with a small outer and inner large card platform at one end.

The wall hole of the capillary tube is connected with a branch pipe, and the open end of the blind pipe of the emitter is sleeved on the outer end of the branch pipe.

A speed control device is installed at the water inlet end of the capillary.

The emitter in the utility model adopts a design with elastic blind pipes (such as rubber pipes) and a blind end of the blind pipe with a normal closed hole. The blind end hole of the emitter is a horizontal long hole. The blind end hole of the rear emitter is opened for irrigation. Since the blind end hole of the emitter is normally closed, it cannot be opened from the outside, and it can be opened by water pressure (0.1kg/cm ² ) during irrigation, which has good anti-negative pressure performance and effectively solves the problem of external blockage. Due to the large flow channel in the inner hole, a small amount of impurities will flow out even if they enter, so there is no internal blockage problem. A branch pipe can be used to connect the capillary and the emitter, thereby greatly reducing the consumption of the capillary (2/3 of the consumption of the capillary can be reduced), saving materials and greatly reducing the construction cost. A water flow speed controller is installed at the water inlet end of each capillary, which effectively solves the problem of unbalanced water supply between the capillaries. When used in a greenhouse, the error of water flow between any two points in the shed is less than 10%, which fully complies with the national standard. Require. The emitter can be directly connected to the capillary pipe through the pipe joint, or can be connected to the capillary pipe through the branch pipe; the pipe joint and the emitter can be plugged and clamped.
