Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a pesticide spraying device for crop cultivation. Background Art

[0002] In agricultural production, pesticides are used to prevent and control pests and diseases and regulate crop growth. Liquid pesticides are often sprayed onto crops. Vehicle-mounted liquid pesticide sprayers are currently available. These devices attach a tank containing liquid pesticide to a cart, allowing operators to push the cart while spraying the liquid pesticide. This significantly reduces the operator's workload. Furthermore, the tank's capacity is significantly increased, significantly improving work efficiency.

[0003] After searching, the Chinese patent publication number CN219660755U discloses a garden pesticide spraying device, including a frame, a medicine storage barrel, a stirring assembly and a spraying mechanism, the medicine storage barrel is connected to the frame, the stirring assembly is arranged inside the medicine storage barrel, the stirring assembly is used to stir the pesticide inside the medicine storage barrel, the spraying mechanism is connected to the medicine storage barrel, the spraying mechanism includes a pump, a tee, two nozzles, a support seat, a positioning sleeve and an insertion rod, the input end of the pump is connected to the medicine storage barrel, the output end of the pump is connected to the input end of the tee, the two nozzles are respectively connected to the two output ends of the tee, the support seat is fixed on the frame, the insertion rod is fixedly connected to the positioning sleeve, the insertion rod is rotatably connected to the support seat, and the output end of the tee passes through the positioning sleeve. The aforementioned patent has the following shortcomings: Some vegetables are planted directly on the ground, while others are planted high up on planting racks. Although this patent can improve the efficiency of pesticide spraying, the height of the pesticide nozzle is fixed, making it impossible to spray vegetables planted high up on the planting racks. As a result, the practicality of this device needs to be improved. In view of this, we propose a pesticide spraying device for crop cultivation. Utility Model Content
