Description

Technical Field

[0001] The utility model relates to the technical field of plant protection equipment, in particular to a spray device for plant protection. Background Art

[0002] Plant protection drones are used in the agricultural field, such as crop spraying, supervision and care. When used for spraying, a water tank and multiple nozzles connected to the water tank are installed on the plant protection drone for spraying. The nozzles are installed on the plant protection drone through spray booms.

[0003] After searching the Chinese patent with publication number CN207639337U, a spray device for a plant protection UAV is disclosed. Through the cooperation of a first motor, a first screw rod and a first active slider, as well as the cooperation of a second motor, a second screw rod and a second active slider, the spraying spacing can be automatically adjusted. During the UAV flight spraying process, the spraying spacing can be adjusted without stopping the spraying. It can freely switch between crops with different planting spacings and adapt to the spraying of crops with different planting spacings, which greatly saves time and improves spraying efficiency.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. Different spray structures are controlled by multiple motors respectively, but the poor synchronization makes it difficult to ensure that the spacing between the spray structures is the same, resulting in different spray volumes in different intervals and high costs. The two sides are driven by motors respectively, which can only ensure that there are three spray structures for spraying plant protection treatment, reducing the use efficiency of the plant protection spray device.
