[0002] Blueberry fruit is rich in nutrients, which can prevent brain nerve aging, protect eyesight, strengthen the heart, fight cancer, soften blood vessels, enhance human immunity, etc. Therefore, the cultivation of blueberry is becoming more and more widespread.

[0003] Blueberry is a low shrub. In my country's low-latitude and high-altitude areas, due to the high humidity, blueberry is prone to gray mold. The existing prevention and control of gray mold is generally through spraying fungal drugs. Due to the terrain of low-latitude and high-altitude areas, the labor intensity of relevant staff is increased, and the efficiency of spraying fungal drugs is low. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes an underground pesticide spraying system.

[0005] The present invention proposes an underground pesticide spraying system, comprising a high-pressure pump, a dispensing mechanism, a main delivery pipe, a pre-buried pipe and a pesticide spraying riser, wherein:

[0006] Dispensing facilities are used to mix water with medications;

[0007] The high-pressure pump is connected with the dispensing mechanism and the main delivery pipe, and the high-pressure pump is used to deliver the liquid medicine in the dispensing mechanism to the main delivery pipe;

[0008] The pre-buried pipe is buried underground, one end of the pre-buried pipe is connected to the main conveying pipe, the spraying riser is connected to the pre-buried pipe, and one end of the spraying riser away from the pre-buried pipe extends out of the ground;

[0009] The pre-buried pipes and the main delivery pipes are both high-pressure pipes made of PPR materials. The pre-buried pipes are buried in the field. Multiple spraying risers can be set, and the multiple spraying risers are staggered and evenly distributed in the field. When in use, a mobile pipe can be connected to one or more of the spraying risers, and the end of the mobile pipe is connected to a high-pressure spray gun. The high-pressure pump transports the prepared liquid medicine in the dispensing mechanism through the main delivery pipe and the pre-buried pipe to the high-pressure spray gun and sprays it on the plant liquid surface through the high-pressure spray gun.

[0010] The dispensing mechanism can be a dispensing barrel in the prior art, in which medicine and water are placed and mixed manually. In some specific embodiments, the dispensing mechanism includes a dispensing barrel, a water pump and a stirring device. The water pump is connected to the dispensing barrel through a pipeline, and is used to transport water into the dispensing barrel. The stirring device is installed on the dispensing barrel and is used to stir the mixture in the dispensing barrel.

Specifically, an inner ring of the elastic separation ring is fixed on the rotating tube, and an outer side surface of the elastic separation ring is fixed on the upper fixed head. The lower connecting chamber is connected to the liquid storage chamber. The pressure in the upper high-pressure chamber is greater than the pressure of the fluid liquid in the support tube, thereby increasing the sealing performance.

[0018] In some embodiments, a connecting through hole is formed on the upper fixing head, and the connecting through hole connects the lower connecting cavity and the liquid storage cavity.

[0019] As a further optimized solution of the present invention, there is liquid in the upper high-pressure sealing chamber, a liquid inlet hole is opened on the upper fixed head, the liquid inlet hole is connected to the upper high-pressure sealing chamber, and a sealing cover is provided in the liquid inlet hole. The liquid can be the medicine sprayed in the pre-buried pipeline.
