Description

Technical Field

[0001] The utility model relates to the technical field of pesticide spraying, in particular to pesticide spraying equipment suitable for farmland movement. Background Art

[0002] Pesticides are widely used in agriculture, forestry and animal husbandry production. They are mainly used to prevent and control diseases, insects, weeds, rodents and other harmful organisms that endanger agriculture and forestry. In agricultural production, they are a general term for a class of drugs used to kill insects, fungi, harmful animals or weeds to protect and promote the growth of plants and crops.

[0003] In agricultural production, pesticides are often needed to remove pests breeding on crops. When mobile pesticide spraying equipment moves and sprays in farmland, it is usually necessary to spray pesticides on the surface of crop leaves. The leaves of some crops are arranged in multiple layers. The mobile pesticide spraying equipment in the prior art always keeps the nozzle at a fixed height during use, resulting in the pesticide spraying equipment only spraying pesticides on the leaves of crops within a certain height range during spraying, thereby affecting the effect of spraying pesticides on crops.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5 As shown, the utility model provides a pesticide spraying device suitable for farmland movement, including a frame 1, a pesticide barrel 2 and a water pump 3 are arranged on the top of the frame 1, and also includes:

[0028] A swingable spraying structure, which is arranged on the frame 1 and is used to spray the leaves of crops at different heights evenly;

[0029] Among them, the swingable spraying structure includes a fixed frame 4, which is installed on one side of the frame 1, and the two sides of the fixed frame 4 are sleeved with a rotating shaft 5, and the outer surface of the rotating shaft 5 is installed with a connecting frame 6 and a gear 7, and a fixed plate 8 is installed inside the fixed frame 4, and a fixed shaft 9 is installed between the fixed plate 8 and the fixed frame 4, and the outer surface of the fixed shaft 9 is sleeved with a return spring 10 and a movable frame 11, and both sides of the fixed frame 4 are provided with a through hole 12, and one end of the connecting frame 6 is installed with a hollow tube 16, and the outer surface of the hollow tube 16 is provided with a plurality of groups of nozzles 17, and one end of the fixed frame 4 is connected with a hose 18, and a connecting plate 21 is installed on one side of the frame 1, and the outer side of the connecting plate 21 is slidably matched with a mounting frame 13, and a driving motor 14 is installed on one side of the mounting frame 13, and a cam 15 is installed on the output shaft of the driving motor 14;

[0030] An adjustment structure, which is arranged on the mounting frame 13 and is used to adjust the height range of the blade spraying;

[0031] The adjustment structure includes a fixing rod 19 , which is installed inside the mounting frame 13 , and a threaded rod 20 is sleeved inside the mounting frame 13 .

[0032] The operation of the driving motor 14 will cause the cam 15 to rotate, so that the cooperation between the cam 15 and the movable frame 11 can drive the movable frame 11 to move upward along the outer surface of the fixed shaft 9. At this time, the cooperation between the movable frame 11 and the gear 7 will drive the rotating shaft 5 to rotate through the gear 7, so that the hollow tube 16 can be driven to rotate through the connecting frame 6. When the cam 15 releases the squeeze on the movable frame 11, the elastic force of the reset spring 10 will drive the movable frame 11 to reset, and then the hollow tube 16 can be controlled to rotate up and down through the connecting frame 6, so that the crops can be sprayed more evenly.

[0033] like Figure 3 As shown, the return spring 10 is elastically supported between the fixed frame 4 and the movable frame 11 .

[0034] The elastic force of the return spring 10 makes the movable frame 11 have good elastic return performance. At this time, since the return spring 10 is in a compressed state, an elastic force is applied to the movable frame 11, so that the hollow tube 16 can be driven to rotate downward through the cooperation between the movable frame 11 and the gear 7.

[0035] like Figure 2 As shown, the outer side of the movable frame 11 is tooth-shaped, and the gear 7 passes through the through opening 12 and is meshed and connected with the movable frame 11.

[0036] Through the tooth-shaped design of the movable frame 11, when the movable frame 11 moves up and down, the gear 7 will be driven to rotate, so that the gear 7 can drive the rotating shaft 5 and the hollow tube 16 to rotate together, so as to control the spray head 17 to spray pesticides up and down.

[0037] like Figure 2 As shown, the bottom end of the movable frame 11 passes through the fixed frame 4 and is arc-shaped, and the cam 15 is in compression contact with the movable frame 11 .

[0038] Through the cooperation between the cam 15 and the movable frame 11 , since the bottom end of the movable frame 11 is arc-shaped, when the cam 15 presses the movable frame 11 , it is easy to push the movable frame 11 to move upward, so that the gear 7 can be driven to rotate by the movable frame 11 .

[0039] like Figure 1 As shown, the water inlet of the water pump 3 is connected to the pesticide barrel 2, and the outlet of the water pump 3 is connected to the hose 18.

[0040] The water pump 3 can extract the pesticide from the pesticide barrel 2 and transport the pesticide to the inside of the hose 18. At this time, through the cooperation between the hose 18 and the hollow tube 16, the pesticide will enter the inside of the hollow tube 16 through the hose 18, and the pesticide will be sprayed out from the end of the nozzle 17.

[0041] like Figure 1 As shown, the water spray hole of the spray head 17 is inclined at 45° toward the moving direction of the frame 1.

[0042] Through the design of the nozzle 17 and the design of bending the nozzle 17, when the nozzle 17 sprays pesticides toward both sides of the pesticide barrel 2, the splashing of the medicine on the user can be effectively reduced.

[0043] like Figure 5 As shown, the fixing rod 19 is sleeved with the connecting plate 21 , and the threaded rod 20 is threadedly connected with the connecting plate 21 .

[0044] Through the cooperation between the threaded rod 20 and the connecting plate 21 and the fixed rod 19 and the connecting plate 21, when the threaded rod 20 rotates, the mounting frame 13 can be controlled to move up and down, so that the cam 15 can be driven up and down by the driving motor 14, and then the height to which the movable frame 11 can rise when the cam 15 squeezes the movable frame 11 can be controlled, so as to control the swing amplitude of the connecting frame 6 and the spraying range of the nozzle 17.

[0045] Working principle:

[0046] When spraying crops, the water pump 3 can be started first to extract the pesticide in the pesticide barrel 2, and at the same time, the pesticide can be transported to the inside of the hose 18. At this time, through the cooperation between the hose 18 and the hollow tube 16, the pesticide will enter the inside of the hollow tube 16 through the hose 18 and be sprayed out from the end of the nozzle 17. Then the user can start the drive motor 14. Through the operation of the drive motor 14, the cam 15 will rotate, so that the movable frame 11 can be driven to move upward along the outer surface of the fixed shaft 9 through the cooperation between the cam 15 and the movable frame 11. At this time, through the cooperation between the movable frame 11 and the gear 7, the gear 7 will drive the rotating shaft 5 to rotate, so that the hollow tube 16 can be driven to rotate through the connecting frame 6. When the cam 15 releases the squeeze on the movable frame 11, the elastic force of the reset spring 10 will drive the movable frame 11 to reset, and then the hollow tube 16 can be controlled to rotate up and down through the connecting frame 6, so that the crops can be sprayed more evenly.
