Description

Technology Field

[0001] The present invention relates to a nutrient solution spraying vehicle, and more specifically, to a nutrient solution spraying vehicle that sprays the nutrient solution and effectively removes residual nutrient solution from the nozzle, making it convenient to manage. Background Technology

[0003] In agriculture, the proper supply of nutrients is essential to optimize crop growth. Accordingly, hydroponics is becoming increasingly widespread alongside soil cultivation, and in hydroponics, a nutrient solution is used to supply the inorganic nutrients required by crops by dissolving them in water.

[0004] Nutrient solutions can be adjusted according to the growth stage and environment of crops, enabling more precise nutrient supply than soil cultivation and improving the growth rate of crops. Conventional nutrient solution supply methods have mainly been carried out through drip irrigation systems, sprinkler systems, or Nutrient Film Technique (NFT) systems.

[0005] While these methods allow for precise nutrient solution supply, uniform application may be difficult in large farmlands or greenhouses, and there is a possibility of problems arising where the nutrient solution is over- or under-supplied in specific areas.

[0006] However, in existing technology, problems occurred where the nutrient solution remained inside the nozzle, causing clogging, or the solution was sprayed unevenly.

[0007] Furthermore, conventional spraying devices have been bulky, causing inconvenience during transport, and the difficulty in freely adjusting the spray angle has resulted in reduced pest control efficiency depending on various terrains and crop heights. Therefore, there is a need for improved technology that maximizes the spraying efficiency of hydroponic spraying vehicles, resolves the issue of nutrient solution residue inside the nozzle, and enables effective pest control operations in diverse environments.

The tank section (1210) may be formed with a sealed structure and an appropriate capacity so that a sufficient amount of nutrient solution can be stored. Additionally, the tank section (1210) may have an inlet formed on the top with a lid for injecting the nutrient solution, and a connection port formed on the bottom to connect a pipe connected to the nutrient solution pump section (1220).

[0040] The above-mentioned nutrient solution pump unit (1220) may be configured to apply pressure to the nutrient solution stored in the above-mentioned tank unit (1210) and transfer it toward the above-mentioned nozzle unit for spraying. At this time, the above-mentioned nutrient solution pump unit (1220) may transfer the nutrient solution at a constant pressure to ensure stable spraying.

[0041] The above-mentioned nutrient valve section (not shown) is provided downstream of the above-mentioned nutrient pump section (1220) to control the flow of the nutrient solution and may be made of a check valve.

[0042] The nozzle unit is configured such that one end is connected to the nutrient valve unit and the other end is connected to the spray unit (1300), thereby allowing the nutrient solution supplied by the nutrient pump unit (1220) to be sprayed.

[0043] The above-mentioned spray unit (1300) is configured to allow a nozzle unit to be inserted inside and can be arranged to guide a flow path so that the nutrient solution can be effectively sprayed.

[0063] As such, the above-mentioned nutrient solution spraying vehicle (1000) can be configured to adjust the spraying angle and volume according to the working environment.

[0064] Additionally, the spraying unit (1300) may be arranged at regular intervals according to the height of the first frame (1510) and the second frame (1520), and configured so that a pair of nozzles can be installed in both directions at each height. Through this, it can be designed to spray nutrient solution at various heights.

[0065] The above control unit (1600) may be configured to perform the role of coordinating the overall operation of the above-mentioned liquid pest control vehicle (1000) and may be mounted on the above-mentioned transport unit (1100).

[0066] The above control unit (1600) may be configured to control the spraying of the nutrient solution, the operation of the rotation unit (1500), and the injection of air by the air unit (1400).

[0067] For example, the control unit (1600) may be configured to control the movement and steering of the transfer unit (1100) and to adjust the spray angle of the rotation unit (1500) by a user's command.

[0068] In addition, the control unit (1600) may be configured to control the amount of nutrient solution sprayed by controlling the operation and pressure intensity of the nutrient solution pump unit (1220).

[0069] When the spraying of the nutrient solution is completed, the control unit (1600) can open the drain valve so that the residual nutrient solution located inside the nozzle unit extending in the height direction along the first frame (1510) and the second frame (1520) is removed by gravity.

[0070] After that, the control unit (1600) can operate the air pump unit (1410) so that high-pressure air blows out and removes the liquid remaining inside the nozzle unit.

[0071] Meanwhile, the control unit (1600) may be configured to generate an alert sound when the operation of the nutrient pump unit (1220) is stopped and a preset time has elapsed, then open the drain valve and automatically operate the air pump unit (1410). The control unit (1600) configured in this manner has the effect of removing the residual nutrient solution inside the nozzle unit even if the user forgets to operate the air pump unit (1410).
