However, in the existing irrigation area, the area of water-saving irrigation is less than 40%, the area of high-efficiency water-saving irrigation (short for sprinkler irrigation, micro-irrigation and high-standard low-pressure pipeline water delivery irrigation, etc.) is less than 15%, and the area of sprinkler irrigation and micro-irrigation is insufficient. 6%
The laying process involves labor and machinery. There is no technology in the market that processes raw materials on site to complete mechanized construction at one time, and there is no equipment that can form straw pipes at one time.

[0063] Such as Figure 7 to Figure 10 As shown, the difference between the second embodiment and the first embodiment is that there are three blades 83, and the three blades are evenly fixed on the outer periphery of the solid structure of the second half of the tube inner diameter adjustable unit 84, and the adjacent blades 83 The angle between them is 120°, and three linear gaps can be formed on the formed straw pipe.
[0064] In the second embodiment, there are three elastic pieces 86 . Preferably, the front ends of the three blades 83 are respectively located in the gaps between adjacent elastic pieces 86 .
[0065] The present invention is not limited thereto, and the number of blades 83 can be four, five, etc., and multiple blades are evenly fixed on the outer periphery of the solid structure of the rear half of the tube inner diameter adjustable unit 84 .
[0066] The number of elastic pieces 86 and the number of blades 83 in the present invention can be the same or di...

The invention provides a straw pipeline forming device used for irrigation, and belongs to the technical field of straw pipeline preparation. A straw raw material moves and is shaped from the rear tothe front in the pipeline forming device; and the pipeline forming device comprises a cylindrical outer wall and an adjusting mechanism arranged in the outer wall and coaxially arranged with the outerwall for adjusting a thickness of a straw pipeline, the adjusting mechanism is provided with blades used for forming a linear gap on the straw pipeline, and the blades extend in a radial direction tothe outer wall and are fixed onto the outer wall. The pipeline forming device provided by the invention makes the thickness of the straw pipeline adjustable, and can form the linear gap on the strawpipeline while forming the straw pipeline, thereby making the straw pipeline have the dual functions of the irrigation and water discharge.
Description
technical field [0001] The invention belongs to the technical field of straw pipe preparation, and in particular relates to a straw pipe forming device for irrigation. Background technique [0002] After years of hard work, by the end of 2011, the national irrigated area reached 68 million hm2 (1.002 billion mu), of which the irrigated area of cultivated land was 61.467 million hm2 (922 million mu), and the irrigated area exceeded half of the cultivated land area for the first time. However, in the existing irrigation area, the area of water-saving irrigation is less than 40%, the area of high-efficiency water-saving irrigation (short for sprinkler irrigation, micro-irrigation and high-standard low-pressure pipeline water delivery irrigation, etc.) is less than 15%, and the area of sprinkler irrigation and micro-irrigation is insufficient. 6%. It should be known that among the above irrigation forms, except for sprinkler irrigation and micro-irrigation, most of the ...
