Water feeder for farm irrigation

Abstract

The invention discloses a water feeder, in particular to a water feeder for farm irrigation. The water feeder comprises a pipe body fixed on a farmland irrigation pipe mesh, a pipe joint fixedly connected with the pipe body, a sliding block for sealing the pipe joint, and a water discharge pipe, wherein an inner taper sleeve is fixed on the inner wall of the pipe body, the inner wall of the innertaper sleeve is axially provided with a guide rail for the sliding block sliding vertically, the water discharge pipe comprises an outlet pipe and a socket pipe, the outlet pipe is communicated the inner cavity of the socket pipe, the socket pipe passing through the pipe joint pushes the sliding block to move downwards, and the cannula is detachably connected to the pipe joint. The water feeder for farm irrigation has the advantages that the structure is simple, the use is convenient, the water flow under the premise of ensuring irrigation can be effectively controlled, and the damage of the irrigation pipe mesh is avoided.

Description

technical field [0001] The invention discloses a water feeder, in particular to a farmland irrigation water feeder. Background technique [0002] At present, most of the farmland irrigation still continues the irrigation methods of canal water delivery and large and small flood irrigation. In order to save irrigation water, pipeline irrigation has become the main form of agricultural water-saving projects. This kind of pipeline water supply irrigation project is to lay a pipe network in the farmland, set a gate valve at each irrigation node of the pipe network, and use a water pump to supply water to the pipe network. When a certain piece of farmland needs to be irrigated, it is only necessary to open the gate valve at the corresponding position to discharge water. , when the irrigation work is completed, the water pump is turned off. [0003] The invention patent application with the application publication number CN105782553A discloses a farmland irrigation water feeder, ...

AI Technical Summary

Problems solved by technology

Due to the large water flow rate of the water feeder, when the drip irrigation pipe network laid in the farmland is supplied with water, the high pressure of the water flow often leads to the pipe network cracking or even large-scale water leakage.
