An underground rotary lifting sprinkler irrigation fixed support device

Abstract

The invention relates to an underground rotary lifting sprinkling irrigation fixing and supporting device. The sprinkling irrigation fixing and supporting device comprises a fixing sleeve, a lifting pipe sleeved with the fixing sleeve and a seal pipe head arranged at the top of the fixing sleeve; a reset spring arranged on the outer wall of the lifting pipe in a sleeving mode is arranged between the seal pipe head at the upper end of the fixing sleeve and a convex ring at the bottom of the lifting pipe, an upper limiting ring and a lower limiting ring are arranged in the lifting pipe, an annular rubber seal part is arranged at the outer side of the upper limiting ring, a floating ball is arranged between the upper limiting ring and the lower limiting ring, a drain pipe is arranged at the top end of the lifting pipe, a conical soil-preventing plug is arranged at the top of the drain pipe, and the bottom of the drain pipe is of a zigzag structure. The problem that a farmer carries pipelines back and forth to install a support nozzle is solved, a convenience body can be directly installed in the middle of a land by means of the technology without occupying land space or affecting cultivation, labor cost is reduced, and labor productivity is improved. After a water pump is turned off, the convenience body will be pulled back underground along with bounce force of the reset spring.

Description

technical field [0001] The invention relates to the technical fields of spraying devices, atomizing devices, nozzles, etc., and in particular to a fixed support device for underground rotary lifting sprinkler irrigation. Background technique [0002] At present, the fixed sprinkler irrigation convenient body used in farmland irrigation in our country has many defects, resulting in inconvenient use, so it has encountered a lot of resistance in promotion. Although it has been promoted for many years, it still has not been promoted. Specifically, because the existing convenient body is exposed to the ground, it will cause obstacles and inconvenience to farmers when they are plowing and harvesting, and it is easy to crash it, so it is very inconvenient to use.

Problems solved by technology

[0002] At present, the fixed sprinkler irrigation convenient body used in farmland irrigation in our country has many defects, which leads to inconvenient use, so it has encountered a lot of resistance in promotion. Although it has been promoted for many years, it has not yet been promoted.

Specifically, because the existing convenient body is exposed to the ground, it will cause obstacles and inconvenience to farmers when they are plowing and harvesting, and it is easy to crash it, so it is very inconvenient to use.

[0003] A convenient body that can be hidden below the surface. The floating ball is made of rubber, which is easy to deform and leak under high water pressure. If it is set as a densely structured floating ball, its buoyancy will be poor, resulting in poor sealing effect. The nozzle standpipe is inserted, resulting in complex structure, high cost, and easy to leak
