Drop irrigation device for field planting

Abstract

A drop irrigation device for field planting comprises a vertical fixing rod, a water storage hopper, and a connecting piece connecting the water storage hopper and the fixing rod. A water inlet is formed in the top end of the water storage hopper and connected with a tap water pipe. A water outlet pipe is arranged at the bottom end of the water storage hopper and connected with an annular water distribution pipe, and dripping heads are evenly distributed on the annular water distribution pipe. Each dripping head comprises a shell, wherein the shell is composed of a straight pipe part and a conical part, a water partition board is arranged in the conical part, the edge of the water partition board is connected with the inner wall of the conical part, a protruding column is arranged in the center of the water partition board, a through hole is formed in the center of the protrusion column, a sawtooth-shaped protruding block is arranged on the upper surface of the water partition board, and inclined plates vertically spaced are disposed on the straight pipe part. The device is simple in structure, the drop irrigation speed can be controlled, and water source waste is effectively prevented.

Description

technical field [0001] The invention relates to the field of field planting, in particular to a drip irrigation device for field crops. Background technique [0002] At present, in the saving drip irrigation watering method for planting, it is mainly to put the water pipe at the watering position, then prick a small hole with a needle at the lower end of the water pipe, and let the water drip out from the small hole, and the effect of doing this is The disadvantage is that the water flow in the water pipe generally has pressure. Due to the effect of the pressure, the water droplets flowing out of the small hole are too large and present a spray state, which cannot meet the requirement of water conservation. Moreover, plants cannot absorb water in a very short period of time, and are often evaporated by the high temperature of sunlight, resulting in a waste of water resources. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present inven...

Due to the effect of the pressure, the water droplets flowing out of the small hole are too large and appear to be sprayed, which cannot meet the requirements of water conservation.

Moreover, plants cannot absorb water in a very short period of time, and are often evaporated by the high temperature of sunlight, resulting in a waste of water resources.
