Self-lifting sprinkling irrigation device capable of drilling soil bidirectionally

Abstract

The invention discloses a self-lifting sprinkling irrigation device capable of drilling the soil bidirectionally, and belongs to the technical field of irrigation. The device comprises an underground rotary sprayer, an inner pipe, an outer pipe, a ball stopper, a ball, a supporting ring, and a drill bit. A water outlet is arranged on the top of the rotary sprayer. The outer diameter of the inner pipe is less than the inner diameter of the outer pipe. A water inlet / outlet is arranged on the lateral wall in the upper portion of the outer pipe. The ball stopper is provided with a through hole. The aperture of the through hole and the inner diameter of the supporting ring are both less than the spherical diameter of the ball. The underground rotary sprayer is arranged at the upper end of the inner pipe and is located outside the outer pipe. The inner pipe is inserted in the outer pipe and can move axially relative to the outer pipe. The drill bit is arranged at the lower end of the outer pipe. The supporting ring is arranged at the lower end of the inner pipe and is in close contact with the lateral wall of the inner pipe, thereby forming the bottom of the inner pipe. The ball stopper is arranged at the upper end of the inner pipe and is located below the underground rotary sprayer. The ball is arranged inside the inner pipe and can move axially between the supporting ring and the ball stopper. The self-lifting sprinkling irrigation device can be installed by drilling downward, can drill upward above the ground, and can lift automatically, thereby increasing the installation efficiency and the irrigation efficiency.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a self-elevating sprinkler irrigation device capable of drilling soil in two directions. Background technique [0002] Sprinkler irrigation technology is a high-efficiency water-saving irrigation technology for farmland. It can spray water evenly and reduce labor intensity. It is widely used in today's agricultural operations. As the key equipment, sprinkler irrigation device, its structure and placement are very important. In order to avoid affecting agricultural operations such as normal farming or harvesting in the field, some buried sprinkler irrigation devices have appeared. [0003] For example, the existing technology provides a buried automatic telescopic integrated sprinkler irrigation equipment, which is connected to the water pipeline, including casings, primary telescopic pipes and secondary telescopic pipes that are sequentially socketed from outside to inside ,...

AI Technical Summary

Problems solved by technology

[0006] The sprinkler irrigation devices provided by the prior art require manual or mechanical excavation of the soil at the installation point for installation, and casings are required, which not only cause the cost of the sprinkler irrigation system, especially the high installation cost, but also the installation quality is difficult to control

Moreover, the sprinkler irrigation device provided by the prior art cannot be self-elevating underground in the case of a single water supply system, which limits its application.
