Automatic telescopic out-of-ground pile for spray/drop irrigation

Abstract

The invention belongs to the technical field of water-saving irrigation and in particular relates to an automatic telescopic out-of-ground pile for spray / drop irrigation. The automatic telescopic out-of-ground pile comprises a tee joint with an internal thread, an out-of-ground pile assembly with a sleeve-type telescopic structure and a plug; one end of the out-of-ground pile assembly is connectedwith the tee joint with the internal thread, and the other end of the out-of-ground pile assembly is connected with a straight tube with an external thread; and the out-of-ground pile assembly is further provided with a connecting device for connecting the plug. The invention provides the automatic telescopic out-of-ground pile for spray / drop irrigation, a telescopic function is realized by the out-of-ground pile assembly with the sleeve structure, and the out-of-ground pile assembly is plugged by the plug after crops are harvested, so that sundries are prevented from entering the out-of-ground pile, and the anti-plugging capability is improved. The out-of-ground pile assembly can be freely telescopic, is exposed out of the earth surface during irrigation and is retracted under the groundafter the crops are harvested, so that the tillage operation of an agricultural machine is not affected, the labor efficiency is greatly increased, out-of-ground pile damage caused by tractor ploughing operation is avoided, the loss is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water-saving irrigation, and in particular relates to an automatic retractable ground pile for spraying and drip irrigation. Background technique [0002] The water-saving irrigation system includes the underground pipe network, the above-ground pipe network and the sprinkler, and the out-of-ground pile is an indispensable connector for connecting the above-ground pipe network and the underground pipe network. The traditional out-of-ground piles do not move after being connected and installed. Since the out-of-ground piles are exposed to the ground and cannot be moved, it brings inconvenience to the operation of agricultural machinery such as plowing, plowing, and land preparation in the second year, reduces work efficiency, and increases The damage rate of the ground pile is reduced, and the cost is increased. Contents of the invention [0003] The object of the present invention is to provide an auto...
