Technical Field
[0001] The utility model relates to the field of pesticide spraying devices, in particular to a pesticide sprayer. Background Art
[0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. During agricultural production or forestry planting, crops are often threatened by pests and diseases. In order to prevent and control pests and diseases, farmers have to spray pesticides on crops through spray devices. Spraying pesticides on crops can effectively reduce pests on crops and increase crop yields. Currently, commonly used pesticide sprayers are shoulder-back and cart-type.
[0003] Most pesticide sprayers currently on the market still require handheld spray guns to spray pesticides at different angles, which results in uneven spraying and increases farmers' workload. In addition, when spraying pesticides, it is generally necessary to spray diluted pesticides on the stems and leaves of plants in proportion to achieve the best prevention and control effect. Most growers still dilute powdered pesticides directly with water before spraying, but the diluted liquid can easily damage the stems and leaves due to uneven concentration. Utility Model Content
[0004] In response to the above problems, the utility model provides a pesticide sprayer. By arranging a pesticide stirring device in the hand-push pesticide sprayer, the concentration of the diluted pesticide liquid is made more uniform. A two-way adjustable angle spray gun is used to spray pesticides on crops or trees on both sides of the road, reducing the workload of farmers.
[0005] The technical solution of the utility model is as follows:
[0006] A pesticide sprayer comprises a pesticide storage box, a stirring device is provided in the pesticide storage box, a pouring inlet is provided at one end of the top of the pesticide storage box, and a medicine barrel is movably connected to the pouring inlet; a supporting device is provided at the other end of the top of the pesticide storage box, spray guns are movably connected on both sides of the supporting device, a movable device is provided in the supporting device, the bottom end of the movable device is movably connected to the spray gun, the bottom end of the spray gun is connected to a medicine delivery device, and the other end of the medicine delivery device is provided inside the pesticide storage box.

[0017] In a further technical solution, a universal wheel is provided at the same end of the bottom of the pesticide storage box as the handle, and a directional wheel is provided at the other end of the bottom of the pesticide storage box. The directional wheel can ensure linear motion when the pushing device moves. When the directional wheel encounters an obstacle, the universal wheel can be rotated to improve the obstacle-crossing ability of the device chassis.
[0018] The beneficial effects of the utility model are:
[0019] 1. The utility model can automatically adjust the angle of the spray gun to spray pesticides on crops or trees, and adopts simultaneous spraying on both sides, which reduces the workload of farmers during spraying.
