Description

Technical Field

[0001] The invention relates to the field of pesticide spraying devices, in particular to a pesticide spraying machine. Background Art

[0002] Agriculture is an industry that utilizes 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 diseases and pests. In order to prevent and control diseases and pests, 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 on the market still require handheld spray guns to spray pesticides at different angles, which results in uneven spraying and increases the workload of farmers. In addition, when spraying pesticides, it is generally necessary to spray the 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 cause damage to the stems and leaves due to uneven concentration. Summary of the invention

[0004] In view of the above problems, the present invention 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 present invention is as follows:

[0006] A pesticide sprayer comprises a pesticide storage box, wherein a stirring device is arranged inside the pesticide storage box, a pouring inlet is arranged 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 arranged at the other end of the top of the pesticide storage box, spray guns are movably connected to both sides of the supporting device, a movable device is arranged inside 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 arranged inside the pesticide storage box.

[0007] The working principle of the above technical solution is as follows:

[0008] The invention provides a pesticide sprayer with adjustable angle and uniformly mixed pesticide liquid. When it is used, the pesticide liquid is poured into a pesticide storage box, the pesticide and water are mixed more uniformly through the stirring action of a stirring device, the pesticide liquid is sent to a spray gun through a medicine sending device to realize pesticide spraying, when the angle of the spray gun needs to be adjusted, the spray head can be driven by a movable device to rotate with the connection point of the spray gun and a supporting device as the center of a circle, and the movable device is stopped when the spray gun rotates to a proper angle, and the pesticide spraying range of the spray gun is realized at this time; when the area for spraying pesticide is large and more pesticide is needed, the pouring inlet can be connected to an external medicine barrel to expand the storage capacity.

[0009] The invention can automatically adjust the angle of the spray gun to spray pesticides on crops or trees, and simultaneously sprays on both sides, thereby reducing the workload of farmers during spraying. Furthermore, the sprayed pesticides are fully stirred, and the pesticides are mixed more evenly, thereby reducing damage to stems and leaves.

[0010] In a further technical solution, the stirring device includes a stirring shaft arranged in the pesticide storage box and a motor rotatably connected to the stirring shaft. The stirring action of the stirring device enables the pesticide and water to be mixed more evenly, thereby reducing the damage to the stems and leaves caused by uneven concentration during spraying.

[0033] The present invention provides a pesticide sprayer with adjustable angle and uniformly mixed pesticide liquid. When it is used, the pesticide liquid is poured into the pesticide storage box 10, and the stirring action of the stirring device makes the pesticide and water mixed more uniformly. The pesticide liquid is delivered to the spray gun 50 through the medicine delivery device to realize pesticide spraying. When it is necessary to adjust the angle of the spray gun 50, the spray head can be driven by the movable device to rotate with the connection between the spray gun 50 and the support device 40 as the center of the circle. When the spray gun 50 rotates to an appropriate angle, the movable device stops working, and the pesticide spraying range of the spray gun 50 is realized. When the area for spraying pesticides is large and more pesticides are needed, the pouring inlet 15 can be connected to an external medicine barrel 16 to expand the storage capacity.

[0034] The invention can automatically adjust the spray gun to a 50-degree angle to spray pesticides on crops or trees, and simultaneously sprays on both sides, thereby reducing the workload of farmers during spraying. Furthermore, the sprayed pesticides are fully stirred, and the pesticides are mixed more evenly, thereby reducing damage to stems and leaves.

[0035] In another embodiment, if Figure 2 As shown, the stirring device includes a stirring shaft 21 arranged in the pesticide storage box 10 and a motor 20 rotatably connected to the stirring shaft 21. The stirring action of the stirring device allows the pesticide and water to be mixed more evenly, thereby reducing the damage to the stems and leaves caused by uneven concentration during spraying.

[0036] In another embodiment, fixed blocks are provided on both sides of the support device 40, and through holes are provided on the fixed blocks for the spray gun 50 to pass through. Screws 41 are provided on both sides of the fixed blocks to penetrate the fixed blocks and rotatably connect the spray gun 50. The spray gun 50 is fixed to the support device 40 by the screws 41 to ensure the stability of the spray gun 50 when the angle is adjusted.

[0037] In another embodiment, the end of the screw 41 is rotatably connected to a circular piece having a diameter greater than that of the screw 41, and a circular groove cooperating with the circular piece is provided on the outer wall of the spray gun 50. A circular piece is provided at the end of the screw 41 to cooperate with the circular groove of the spray gun 50, so that the spray gun 50 can be conveniently rotated up and down with the circular piece as the center, thereby achieving the purpose of changing the angle of the spray gun 50.

[0038] In another embodiment, if Figure 3 and Figure 4As shown, the movable device includes a support rod 42 installed on the top of the support device 40, and telescopic rods 43 are provided on both sides of the support rod 42. The telescopic rod 43 can be an electric telescopic rod or a small telescopic cylinder. The fixed end of the telescopic rod 43 is hinged to the support rod 42, and the piston end of the telescopic rod 43 is hinged to the spray gun 50.
