Embedded drip irrigation tube dripper

Abstract

The invention relates to an embedded drip irrigation tube dripper, which comprises a dripper tube body, a dripper tube orifice and a dripper tube cavity. The dripper is divided into four faces; the middle part of one of the four faces of the dripper is locally provided with concave inlet water filter holes along the circumference; the inlet water filter holes are communicated with the dripper tube cavity; both sides of the face on which the inlet water filter holes are arranged are respectively provided with wave-shaped runners along the circumference; the face of the dripper tube body, which is at one side of the inlet water filter holes and the wave-shaped runners, is provided with U-shaped water outlet troughs along the circumference; the face of the dripper tube body, which is at the other side of the inlet water filter holes and the wave-shaped runners, is provided with rectangular water flowing cavities along the circumference; and the face of the dripper tube body, which is opposite to the inlet water filter holes and the wave-shaped runners, is provided with wave-shaped water return cavities along the circumference. Particles in water flow can flow along with the wave of the water flow by the wave-shaped runners; water flow dead corners cannot be generated; the water flow is in a turbulent condition; and the U-shaped water outlet troughs are arranged at the position of the water outlet of the dripper, and thus, the blocking resistance is excellent. The invention relates to the embedded drip irrigation tube dripper which is simple in process manufacturing and good in dripping effect.

Description

technical field [0001] The invention relates to an embedded drip irrigation pipe dripper. Background technique [0002] At present, in order to save water, agricultural planting implements water-saving drip irrigation. The dripper used for drip irrigation is the main structural component of drip irrigation. The existing pressure-compensated dripper includes the dripper body, and the diaphragm of the dripper body is provided with a cover. There are through holes on the cover, and flow channels are opened between the through holes on the inner surface of the cover; the manufacturing process of this dripper is complicated, and its manufacturing deviation coefficient is higher than that of the non-compensating emitter. [0003] Another external compensation type dripper is directly plugged into the irrigation pipeline, and a constant pressure compensation diaphragm is set in the dripper to improve the uniformity of dripping water. The basic structure of this external compensatio...

Problems solved by technology

[0004] There is also a microgravity dripper detachable drip irrigation pipe, which is composed of a water delivery capillary, a back cover and a dripper body that are correspondingly buckled on it; a positioning column, a staggered reciprocating flow channel wall and a dripper are arranged on the dripper body There is a water outlet hole on the wall of the water delivery capillary, which is matched with the positioning column. On the back cover, there is a back cover fixing protrusion which is pressed against the water delivery capillary and an interference fit with the fixed connection column. Fix the connection hole; the production process and manufacturing process of this dripper are relatively complicated and the cost is too high
