Abstract
The invention discloses a buried anti-blocking drip irrigation pipe, which comprises a PE pipe and cylindrical drippers, wherein the cylindrical drippers are arranged in the PE pipe at intervals, the outer wall of each cylindrical dripper is provided with a water outlet groove, and the side wall of the PE pipe is provided with water outlet holes corresponding to the water outlet grooves; the method is characterized in that: the water outlet of the PE pipe is covered with an elastic diaphragm, and the middle part of the elastic diaphragm is provided with a cross-shaped cutting seam corresponding to the water outlet. The invention has simple structure, the elastic diaphragm is arranged on the water outlet hole of the PE pipe, the cross-shaped cutting seam in the elastic diaphragm corresponds to the water outlet hole, when the water pressure exists in the PE pipe, the water flows out from the cross-shaped cutting seam, and when the water pressure does not exist, the cross-shaped cutting seam is closed, thereby preventing the silt in the soil and the crop root system from entering, avoiding the blockage, being convenient for installation and use, and improving the uniformity of underground irrigation; the service life is prolonged.
Description
Technical Field
The invention relates to an improvement of an irrigation device for buried drip irrigation, in particular to a buried anti-blocking drip irrigation pipe.
Background
The existing underground drip irrigation pipe is composed of a cylindrical dripper and a PE pipe, the cylindrical dripper is arranged in a PE pipe cavity, and a water outlet hole is arranged on the pipe wall of the PE pipe corresponding to a water outlet groove of the cylindrical dripper, so that water in the PE pipe flows into the water outlet groove after passing through a flow channel on the side wall of the cylindrical dripper and then flows out of the water outlet hole on the PE pipe; the disadvantages are that: the underground drip irrigation pipe is buried underground for use, is easy to be blocked by soil, has poor irrigation uniformity, and the root system of crops is easy to invade into a water outlet hole, so that the development speed of underground drip irrigation in the world is finally far behind that of ground surface drip irrigation.
Disclosure of Invention
The invention aims to provide a buried anti-blocking drip irrigation pipe which is simple in structure, convenient to use and not easy to block, improves the uniformity of underground irrigation and prevents the invasion of crop roots.
In order to achieve the above purposes, the technical scheme adopted by the invention is as follows: the buried anti-blocking drip irrigation pipe comprises a PE pipe and cylindrical drippers, wherein the cylindrical drippers are arranged in the PE pipe at intervals, water outlet grooves are formed in the outer walls of the cylindrical drippers, and water outlet holes corresponding to the water outlet grooves are formed in the side walls of the PE pipe; the method is characterized in that: the water outlet of the PE pipe is covered with an elastic diaphragm, and the middle part of the elastic diaphragm is provided with a cross-shaped cutting seam corresponding to the water outlet.
The elastic membrane is a TPE thermoplastic elastic membrane.
The elastic membrane is transparent or semitransparent.
The elastic diaphragm is in a strip shape, two ends of the elastic diaphragm in the length direction are respectively welded on the PE pipe wall by a laser welding machine, and laser welding marks are formed.
The invention has the beneficial effects that: the structure is simple, the elastic diaphragm is arranged on the water outlet hole of the PE pipe, the cross-shaped cutting seam in the elastic diaphragm corresponds to the water outlet hole, water flows out of the cross-shaped cutting seam when water pressure exists in the PE pipe, and the cross-shaped cutting seam is closed when no water pressure exists, so that silt in soil and crop root systems are prevented from entering, blockage is avoided, the installation and the use are convenient, and the uniformity of underground irrigation is improved; the service life is prolonged.
Drawings
FIG. 1 is a schematic view, partly in section, of the structure of the present invention;
FIG. 2 is an enlarged, cross-sectional view taken along line A-A of FIG. 1;
fig. 3 is an enlarged top view of the elastic diaphragm according to the present invention.
In the figure: 1. a PE pipe; 2. a cylindrical dripper; 3. a water outlet groove; 4. an elastic diaphragm; 5. welding marks by laser; 6. cutting a joint in a cross shape; 7. and (7) water outlet holes.
Detailed Description
The present invention was made with reference to fig. 1, 2, and 3.
The buried anti-blocking drip irrigation pipe comprises a PE pipe 1 and cylindrical drippers 2, wherein the cylindrical drippers 2 are arranged in the PE pipe 1 at intervals, water outlet grooves 3 are formed in the outer walls of the cylindrical drippers 2, and water outlet holes 7 corresponding to the water outlet grooves 3 are formed in the side walls of the PE pipe 1, so that water in the PE pipe 1 enters the water outlet grooves 3 through flow channels in the side walls of the cylindrical drippers 2 and then flows out of the water outlet holes 7, and the purpose of underground irrigation is achieved; the method is characterized in that: PE manage 7 of apopore of 1 and cover and be equipped with elastic diaphragm 4, elastic diaphragm 4's middle part is equipped with the cross joint-cutting 6 corresponding with apopore 7, like this, the water that flows out in apopore 7 can flow out from elastic diaphragm 4's cross joint-cutting 6, if PE manages 1 water pressure inadequately, then cross joint-cutting 6 can be closed under self elastic action, the water in PE manages 1 can not flow, simultaneously, outside plant roots and silt also can not get into PE manage 1 in, reach the purpose that prevents to block up.
The elastic membrane 4 is a TPE thermoplastic elastic membrane and is made of TPE thermoplastic materials.
The elastic membrane 4 is transparent or semitransparent.
The elastic membrane 4 is in a long strip shape, two ends of the elastic membrane in the length direction are respectively welded on the wall of the PE pipe 1 through a laser welding machine, and laser welding marks 5 are formed, so that water outlet gaps are formed between two side edges between the two laser welding marks 5 and the outer wall of the PE pipe 1.
When the invention is manufactured, the long-strip TPE thermoplastic elastic membrane is cut out, and meanwhile, the cross-shaped cutting seam 6 is cut out; and finally, welding the two ends of the TPE thermoplastic elastic membrane on the side wall of the PE pipe 1 at the water outlet hole 6 by using a laser welding machine.
