Description

Technical Field

[0001] This utility model relates to the field of sprayers, specifically to a lightweight and simple contour sprayer for strawberries. Background Technology

[0002] A boom sprayer is a motorized sprayer with nozzles mounted on horizontal or vertical booms. This type of sprayer offers high operating efficiency, excellent spray quality, and uniform liquid distribution. It is suitable for large-area spraying of various liquid formulations of pesticides, fertilizers, and plant growth regulators, and is widely used in field crops, lawns, nurseries, and wall-mounted vineyards. Existing lightweight contour-following sprayers for strawberries are difficult to adjust the nozzle position according to the shape of the strawberry plant. This results in a large gap between the nozzle and the strawberry plant, causing the pesticide to be sprayed inaccurately onto the strawberry plant during spraying. This leads to a large waste of pesticide and reduces the spraying effect, failing to achieve the expected purpose of controlling pests and diseases or promoting strawberry growth. In addition, the nozzle position is relatively fixed and cannot be adjusted according to the height of the strawberry plant, reducing its practicality. Therefore, it is necessary to provide a lightweight and simple contour-following boom sprayer for strawberries to solve the above-mentioned technical problems. Utility Model Content
