Double-layer rolled drip irrigation pipe and processing equipment and method thereof

Abstract

The invention discloses a double-layer rolled drip irrigation pipe and processing equipment and method thereof. The double-layer rolled drip irrigation pipe comprises an anti-aging tape layer and an elastic tape layer; the inner surface of the anti-aging tape layer is provided with an energy-dissipating channel; one edge of the inner surface of the anti-aging tape layer is provided with a plurality of outflow channels communicated with the energy-dissipating channel; the energy-dissipating channel is in S shape; the elastic tape layer is attached to the inner surface of the anti-aging tape layer to form a duct tape; an energy-dissipating flow passage is formed between the energy-dissipating channel and the elastic tape layer; an outflow passage is formed between the outflow channels and the elastic tape layer; the side, corresponding to the duct tape, of the outflow channels is provided with a water outlet; the elastic tape layer is provided with a plurality of water inlets communicated with the energy-dissipating flow passage, wherein the water outlet side of the duct tape is a first connection portion, the other side of the duct tape is a second connection portion, the first connection portion is lapped outside the second connection portion. The double-layer rolled drip irrigation pipe can be provided with better service reliability and longer life.

Description

technical field [0001] The invention relates to the technical field of drip irrigation pipes, in particular to a double-layer rolled drip irrigation pipe, processing equipment and a processing method thereof. Background technique [0002] At present, agricultural planting combined with drip irrigation technology has become a trend in the development of green and environmentally friendly agriculture. Drip irrigation pipes are generally laid on the ground. Drip irrigation pipes usually include water pipes and drippers. The drippers are arranged on the inner wall of the water pipes. A turbulent flow channel is formed between the drippers and the water pipes. The nozzle is discharged. Among them, the wall thickness of the drip irrigation pipe is an important indicator that affects the life of the drip irrigation belt. The drip irrigation pipes in the prior art usually use an extruder to extrude the water pipe while inserting a drip head. During the extrusion process, it is affe...

Problems solved by technology

Among them, the wall thickness of the drip irrigation pipe is an important indicator that affects the life of the drip irrigation belt. The drip irrigation pipes in the prior art usually use an extruder to extrude the water pipe while inserting a drip head. During the extrusion process, it is affected by the traction speed. , it is easy to cause uneven thickness of the water pipe wall, which affects the service life. At the same time, the dripper is embedded in the inner wall of the water pipe. Failure, the corresponding crops cannot obtain sufficient water supply and affect growth, resulting in low reliability of drip irrigation pipes
