A PE pipe installation method suitable for reel sprinkler irrigation machines

Abstract

The invention discloses a method for installing a PE pipe suitable for a reel sprinkler irrigation machine. For a reel sprinkler irrigation machine without a PE pipe installed, the PE pipe at the end of the reel is sleeved and installed in the installation space above the reel. The PE pipe The installation system includes a PE pipe raw material roll installation unit, a carriage type PE pipe socket installation unit, a gantry type PE pipe socket installation unit, a reel rotation drive unit and a centralized electric control unit. The PE pipe installation method suitable for the reel sprinkler irrigation machine adopts the method of electrically heating the inside of the PE pipe end through the conical electric heating head assembly, which can greatly reduce the risk of premature aging of the PE pipe end; the gantry type PE pipe The socket installation unit and the carriage type PE pipe socket installation unit are automatic units, which can not only greatly reduce the labor intensity of the operator, but also greatly improve the installation efficiency. It is especially suitable for large diameter, medium and large reel sprinkler irrigation machines. Installation of large thick-walled PE pipes.

Description

Technical field [0001] The present invention relates to a mounting method for a reel sprinkler, which is specifically a PE pipe mounting method suitable for mounting a PE tube on a reel sprinkler, belonging to the technical field of reel sprinkler. Background technique [0002] Spray irrigation is sprayed into the air using a special equipment such as a head to form a water droplets falling to the irrigation method of the surface of the ground and crop surface, and the sprinkler is also known as sprinkler, the sprinkler unit, that is, the special equipment used by sprinkler. [0003] The reel sprinkler can irrigate a large-scale farmland, or the spray amount of the spray amount can also be controlled to meet the different requirements of the user's sprinkling water, which is a sprinkler for the water irrigation. Roll sprinklers generally use water turbine power drive systems, typically mainly include chassis, reels, PE tubes, water turbines, gearboxes, speed compensating devices,...

AI Technical Summary

Problems solved by technology

For large and medium-sized reel sprinkler irrigation machines, the nominal pressure of the PE pipe is usually 0.63-1.6MPa, the outer diameter is usually 65-250mm, the wall thickness of the pipe is usually 4.2-22.7mm, and the weight is relatively large. When installing the PE pipe, the end of the PE pipe is usually heated and softened before being manually socketed. The heating method is usually flame heating or hot oil heating, which is not only labor-intensive, long installation period, and low installation efficiency. Moreover, the way of flame heating or hot oil heating usually damages the outer surface of the end of the PE pipe, which in turn causes the risk of premature aging at the end of the PE pipe, which will reduce the overall quality of the reel sprinkler.
