A fixed sprinkler automatic lifting convenient body

Abstract

The present invention relates to a fixed sprinkling irrigation convenient body capable of automatically rising and falling. The convenient body comprises a fixed sleeve, an elevating pipe inserted in the fixed sleeve and a sealing pipe head arranged on a top of the fixed sleeve; a return spring which sleeves an outer wall of the elevating pipe is arranged between the sealing pipe head at the top end of the fixed sleeve and a convex ring at a bottom of the elevating pipe; an upper limit ring and a lower limit ring are arranged in the elevating pipe; a ring-shape rubber sealing member is arranged on an outer side of the upper limit ring; a floating ball is arranged between the upper limit ring and the lower limit ring; a water draining pipe is arranged at the top end of the elevating pipe; a tapered soil prevention plug is arranged on the top of the water draining pipe; and the bottom of the water draining pipe is a saw-tooth structure. According to the fixed sprinkling irrigation convenient body capable of automatically rising and falling provided by the present invention, the problem that farmers need to move pipes for installing brackets and sprayers back and forth is solved, and the convenient body can be directly placed in the middle of a land by means of the technology without land space occupied, so that labor costs are reduced and a labor productivity rate is improved. When a water pump is closed, the convenient body will be pulled to the land along with a back force of the return spring.

[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
