Description

Technical Field

[0001] This utility model relates to the field of greenhouse planting spraying technology, specifically to a spraying mechanism for greenhouse planting. Background Technology

[0002] Greenhouse cultivation is an agricultural method that involves growing crops such as vegetables and fruits inside a greenhouse. Greenhouses typically use a bamboo and steel frame structure covered with an insulating plastic film to create a controlled environment that regulates temperature and light conditions to promote crop growth.

[0003] Chinese Utility Model Patent Publication No.: "CN 221807664 U" discloses a sprinkler device for planting greenhouses. The rotating shaft of the device can drive two rollers simultaneously. The rotating rollers can then retract and extend a rope. Under the weight of the tube itself, the retracted and extended rope can adjust the height of the tube. Subsequently, the user connects the curved pipe to an external water pipe, and the water inside can enter the tube through the flexible hose and be sprayed directly onto the plants inside the greenhouse through the nozzle. This adjustable nozzle not only facilitates the movement of workers inside the greenhouse but also allows for spraying the greenhouse at a suitable height.

[0004] Although the above-mentioned device can adjust the spray height, it requires multiple pipes to cover the inside of the greenhouse, which increases the spraying cost. In addition, there are overlapping or uncovered areas between the pipe nozzles, which can easily lead to over-spraying or no spraying at all, affecting the growth of plants inside the greenhouse.
