Description

Technical Field

[0001] This utility model relates to the field of plant protection equipment technology, and in particular to a mobile sprayer for use in cotton fields. Background Technology

[0002] Cotton is an important economic crop. During its cultivation, it is necessary to regularly spray pesticides on cotton fields to prevent and control pests and diseases. Since cotton is a shrub-like plant that can reach a height of 1.5 meters, it requires the use of tall plant protection machinery for spraying.

[0003] Existing mobile sprayers use a boom to spray pesticides from the top. Due to the height of cotton plants and their relatively dense planting, the pesticide solution is difficult to reach the bottom of the plant due to obstruction by the leaves and bolls. This results in uneven or no pesticide application to the stems and leaves at the bottom of the plant. Consequently, it is not effective in controlling pests and diseases in cotton. Therefore, a mobile sprayer for cotton fields is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing plant protection equipment is difficult to spray the bottom of plants, and to propose a mobile sprayer for cotton fields.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile sprayer for cotton fields includes a frame, with extension frames on both sides at one end of the frame. A transmission rod is rotatably connected between the extension frames. A drive wheel and an auxiliary wheel are rotatably connected to the bottom of the extension frames. A gearbox is located at the bottom of the frame. A partition is welded to the surface of the frame, with a square hole at the top of the partition. A diesel engine is mounted on the surface of the partition, and a first belt is installed at the output end of the diesel engine. The diesel engine is connected to the gearbox via the first belt. A fixed frame is welded to the top of the frame, and a misting assembly and a pesticide tank are installed inside the fixed frame. A swaying assembly is located between the fixed frame and the transmission rod.

[0007] Preferably, the partition surface has notches around its perimeter for matching fixing brackets.

[0008] Preferably, the misting assembly includes a mist diffuser, the input end of which is connected to the liquid tank via a pipe, the output end of which is fixedly connected to a pleated tube, and the other end of which is fixedly connected to a diffusion nozzle.

[0009] Preferably, a first rotating shaft and a second rotating shaft are staggered on both sides of the diffusion nozzle. The diffusion nozzle is connected to the fixed frame through the first rotating shaft, and the diffusion nozzle is connected to the swing assembly through the second rotating shaft.

[0010] Preferably, an elastic membrane is fixedly connected to both ends inside the pleated tube.

[0011] Preferably, the swing assembly includes a drive roller, a support column, and a rotating wheel. The drive roller is fixedly connected to the body of the drive rod. The support column is fixedly connected to one side of the frame corresponding to the drive roller. A rotating wheel is rotatably connected to one side of the support column. A third rotating shaft is provided on one edge of the rotating wheel. A second belt is provided between the drive roller and the rotating wheel.

[0012] Preferably, a connecting rod is rotatably connected inside the third rotating shaft, and the other end of the connecting rod is rotatably connected to the second rotating shaft.

[0013] Preferably, a guide plate is welded to the bottom of the riser frame at the location corresponding to the drive wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a misting component, uses a mister to generate extremely small liquid water droplets, allowing the liquid mist to diffuse between plants for a long time after spraying, increasing the adhesion efficiency of the liquid mist. The duckbill-shaped diffuser nozzle increases the lateral diffusion of the liquid mist, thereby increasing the spraying area. By setting up a pleated tube to support the swing of the diffuser nozzle, and by using an elastic membrane to keep the internal pipes of the pleated tube smooth in any posture, the pleated parts are prevented from affecting the spraying of the atomized liquid mist.

[0016] 2. This utility model, by setting up a swing assembly, allows the transmission rod to rotate synchronously with the transmission roller when the diesel engine drives the transmission rod. The transmission roller drives the rotating wheel to rotate via a second belt. When the rotating wheel rotates, it pulls the connecting rod via a third rotating shaft. After the connecting rod is stressed, it drives the diffuser nozzle to rotate along the first rotating shaft via the second rotating shaft, causing the diffuser nozzle to swing back and forth from top to bottom. The swing of the diffuser nozzle continuously changes the incident angle of the atomized liquid, allowing the liquid mist to easily enter the bottom of the cotton plant. At the same time, it disturbs the air, increases the activity of the liquid, and further improves the adhesion efficiency of the liquid. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-6 A mobile sprayer for cotton fields includes a frame 1, with extension frames 2 on both sides of one end of the frame 1, a transmission rod 3 rotatably connected between the extension frames 2, a drive wheel and an auxiliary wheel rotatably connected to the bottom of the extension frames 2, a gearbox 4 at the bottom of the frame 1, a partition 5 welded to the surface of the frame 1, a square hole 6 at the top of the partition 5, a diesel engine 7 mounted on the surface of the partition 5, a first belt 8 at the output end of the diesel engine 7, and the diesel engine 7 connected to the gearbox 4 via the first belt 8. A fixing frame 9 welded to the top of the frame 1, a misting assembly and a pesticide tank 10 mounted inside the fixing frame 9, and a swing assembly between the fixing frame 9 and the transmission rod 3.

[0026] It should be noted that the transmission rod 3, drive wheel, auxiliary wheel and gearbox 4 are all existing technologies. The two ends of the transmission rod 3 located inside the riser frame 2 drive the drive wheel to rotate through the chain. The drive wheel maintains the stability of the frame 1 when moving, and the gearbox 4 adjusts the forward gear.

[0027] Furthermore, notches for matching the fixing bracket 9 are provided around the perimeter of the partition 5 surface, so that the partition 5 will not be blocked by the fixing bracket 9 during installation.

[0028] Furthermore, the misting assembly includes a mist diffuser 11. The input end of the mist diffuser 11 is connected to the liquid tank 10 via a pipe. The output end of the mist diffuser 11 is fixedly connected to a pleated tube 12. The other end of the pleated tube 12 is fixedly connected to a diffuser nozzle 13. A first rotating shaft 14 and a second rotating shaft 15 are alternately arranged on both sides of the diffuser nozzle 13. The diffuser nozzle 13 is connected to the fixed frame 9 via the first rotating shaft 14 and to the swing assembly via the second rotating shaft 15. An elastic membrane 1201 is fixedly connected to both ends inside the pleated tube 12.

[0029] It should be noted that: the mist sprayer 11 is existing technology, specifically a pulse mist sprayer 11. The pleated tube 12 is made of nylon to protect the elastic membrane 1201. The elastic membrane 1201 is made of silicone to resist the penetration of the liquid. The diffusion nozzle 13 is duckbill shaped to reduce the longitudinal ineffective diffusion area and increase the lateral effective diffusion area.

[0030] A further advantage of the above is that the mist sprayer 11 produces extremely small liquid droplets, allowing the liquid mist to diffuse between plants for a long time after spraying, thus improving the adhesion efficiency of the liquid mist. The duckbill-shaped diffuser nozzle 13 increases the lateral diffusion of the liquid mist, thereby increasing the spray area. The elastic membrane 1201 keeps the internal tubing of the pleated tube 12 smooth in any orientation, preventing the shape of the pleated tube from obstructing the passage of the atomized liquid mist.

[0031] Furthermore, the swing assembly includes a transmission roller 16, a support column 17, and a rotating wheel 18. The transmission roller 16 is fixedly connected to the body of the transmission rod 3. The support column 17 is fixedly connected to one side of the frame 1, corresponding to the transmission roller 16. The rotating wheel 18 is rotatably connected to one side of the support column 17. A third rotating shaft 19 is provided on one edge of the rotating wheel 18. A second belt 20 is provided between the transmission roller 16 and the rotating wheel 18. A connecting rod 21 is rotatably connected inside the third rotating shaft 19. The other end of the connecting rod 21 is rotatably connected to the second rotating shaft 15.

[0032] A further advantage of the above is that, after the oil extraction machine drives the equipment, the transmission rod 3 drives the transmission roller 16 and the rotating wheel 18 to rotate. Under the combined action of the third rotating shaft 19, the second rotating shaft 15, and the first rotating shaft 14, the diffuser nozzle 13 swings back and forth from top to bottom, allowing the pesticide mist to easily enter the bottom of the cotton plant. At the same time, it disturbs the air, increases the activity of the pesticide solution, and further improves the adhesion efficiency of the pesticide solution.

[0033] Furthermore, a guide plate 22 is welded to the bottom of the riser 2 at the location corresponding to the drive wheel, and the guide plate 22 is used to clear away cotton plants that may be crushed by the drive wheel in the forward path.

[0034] When using this utility model, the gearbox 4 is adjusted to the appropriate forward gear, and then the mist sprayer 11 is started. The mist sprayer 11 atomizes the liquid pesticide and sprays it out. After being sprayed out, it passes through the duckbill-shaped diffuser nozzle 13, which increases the lateral diffusion of the pesticide mist, thereby increasing the effective spraying area. Finally, the diesel engine 7 is started. When the diesel engine 7 drives the transmission rod 3, the transmission rod 3 drives the transmission roller 16 to rotate synchronously, so that the drive wheel drives the sprayer forward. Farmers push the equipment and only need to follow it to the edge of the field to perform a turning operation.

[0035] When moving forward, the drive roller 16 drives the rotating wheel 18 to rotate via the second belt 20. When the rotating wheel 18 rotates, it pulls the connecting rod 21 via the third rotating shaft 19. After the connecting rod 21 is under force, it drives the diffuser nozzle 13 to rotate along the first rotating shaft 14 via the second rotating shaft 15, causing the diffuser nozzle 13 to swing back and forth from top to bottom. When swinging, the elastic membrane 1201 keeps the pipeline inside the pleated tube 12 smooth in any posture, avoiding the pleats from affecting the spraying of the atomized liquid. The swing of the diffuser nozzle 13 continuously changes the incident angle of the atomized liquid, allowing the liquid mist to easily enter the bottom of the cotton plant. At the same time, it disturbs the air, increases the activity of the liquid, and further improves the adhesion efficiency of the liquid. The guide plate 22 pushes aside cotton plants that may be crushed by the drive wheel in the forward path, preventing the cotton plants from being rolled into the drive wheel and crushed, causing economic losses.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
