Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a spraying device for tomato cultivation. Background Technology

[0002] Tomatoes, belonging to the genus *Solanum* of the Solanaceae family, are annual herbaceous plants and one of the most widely cultivated fruits and vegetables worldwide. Tomato cultivation is susceptible to numerous pests and diseases, such as whiteflies, leaf miners, gray mold, early blight, and late blight. These pests and diseases are characterized by rapid spread, wide range of damage, and difficulty in control, making pesticide spraying a crucial method of pest and disease management. However, tomato plants vary in height at different growth stages, reaching 1.0-1.5 meters in height and 0.5-0.8 meters in width at maturity. In high-density planting, the space between plants is limited, and the intertwined branches and leaves form a dense "leaf canopy," placing comprehensive demands on pesticide spraying devices that are efficient, uniform, and adaptable. Currently available unidirectional nozzles struggle to spray pesticides into the interior and underside of the plant, creating spray dead zones and affecting pest and disease control effectiveness. Therefore, researching and optimizing pesticide spraying based on the morphological characteristics of tomato plants has significant practical and application value.

[0003] For example, the spraying device for tomato cultivation disclosed in the authorization announcement number CN213992205U includes a storage tank, a pesticide pump, an infusion pipe, a spray head, and a fixing frame. The storage tank is placed inside the tomato greenhouse and connected to a water source. The pesticide pump is connected to the storage tank and the infusion pipe. One end of the infusion pipe is connected to the pesticide pump, and the other end is connected to the spray head. The fixing frame is fixedly set at intervals between tomato plants. Spray heads are fixedly installed at the top, middle, and bottom positions of the fixing frame, and the spray heads face different directions. The pesticide prepared in the storage tank is delivered to the spray head through the pesticide pump and the infusion pipe. By setting the fixing frame at intervals between tomato plants and installing the spray head on the fixing frame with the spray head facing different directions, the pesticide can be fully covered on the top and bottom of all plants and leaves when spraying, so that the pesticide can be applied to the tomato plants in the greenhouse without direct manual operation.

[0004] Although it achieves the characteristics of being convenient to use, efficient and quick, it does not solve the problems that existing spraying devices are not conducive to convenient reciprocating swing spraying operations, are not convenient for lateral angle adjustment spraying, are not convenient for rotating and folding to unfold for large-area spraying operations, and are not convenient for folding and shrinking for carrying and use together, which affects the uniformity of drug spraying, the range of spraying and efficiency.
