Micro spray head capable of being used for underground embedment

Abstract

The invention discloses a micro spray head capable of being used for underground embedment, and belongs to the technical field of irrigation. The micro spray head comprises an earth borer, a water dispersing plate, a connecting rod, an inner pipe, an outer pipe, a spring, an upper fixing ring and a lower fixing ring, wherein the top of the earth borer is provided with a water outlet; the water dispersing plate is provided with a plurality of water dispersing flow passages of which the upper parts are communicated with the lower parts; the bottom of the outer pipe is connected with an underground embedment type sprinkling irrigation device; the bottom of the inner pipe is provided with a circle of limiting baffle plate; the center of the top of the inner pipe is provided with a flow guider; the upper fixing ring and the lower fixing ring are orderly arranged inside the outer pipe from top to bottom; the inner pipe is mounted in the outer pipe in an axial sliding sleeving manner; the spring is mounted on the inner pipe in a sleeving manner; the limiting baffle plate is located between the upper fixing ring and the lower fixing ring; the spring is located between the upper fixing ring and the limiting baffle plate; the connecting rod is arranged between the water dispersing plate and the inner pipe; the water dispersing plate is connected with the earth borer cooperatively; the earth borer is in contact with the outer pipe when being in a non-working state. The micro spray head provided by the invention is applicable to the underground embedment; a blockage cannot occur; the cultivation is not influenced; a frequent disassembly is not needed; the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a micro-sprinkler which can be used for underground burial. Background technique [0002] Micro-spray, also known as mist spray irrigation, uses a low-pressure water pump water delivery system to deliver water, and sprays water into the air by using a micro-atomizing nozzle (that is, a micro-spray nozzle), so that the water droplets disperse into fine mist droplets, thereby uniformly Sprinkle it above the branches and leaves of the crops or below the crown of the tree. This method can increase soil moisture on the basis of water saving and increase the humidity of the air around the crops. It is suitable for use from the seedling stage to the growth and harvesting stage of crops, and has high adaptability. . As the water spraying part of the micro-spray system, the structure of the micro-spray head directly affects the operation of the micro-spray water. Therefore, in order t...

Problems solved by technology

[0005] The micro-sprinklers provided by the prior art are arranged above the ground, which affects field cultivation and is not conducive to mechanized operations. Moreover, the internal water distribution channels of the micro-spray heads provided by the prior art are closed, and there is a possibility of blockage of the distribution water channels.

At the same time, the micro-sprinklers provided by the existing technology need to be dismantled and returned to the warehouse for storage after the irrigation season, which is easy to cause damage and affect the use of the next irrigation season.
