Description
Technical Field
[0001] This utility model relates to the field of crop planting technology, and in particular to a spraying device for wheat planting. Background Technology
[0002] In wheat cultivation, pest and disease control is a key link in ensuring yield and quality. As the core tool for pest and disease control, the performance of spraying equipment directly affects the control effect and agricultural production efficiency. With the development of modern agriculture towards precision and efficiency, the requirements for wheat spraying equipment are increasing. It is necessary not only to achieve large-area rapid spraying, but also to ensure uniform spraying of pesticide solution and high pesticide utilization rate, so as to reduce pesticide waste and environmental pollution, while improving the ability to control pests and diseases at different growth stages of wheat.
[0003] Existing wheat spraying equipment typically includes a liquid tank, a stirring mechanism, a delivery pipeline, a pumping system, and a spraying device. In the stirring stage, a mechanical stirring method driven by a single motor is generally adopted. The motor drives the transmission shaft, which causes the stirring blades fixed on the shaft to rotate unidirectionally in the liquid tank, aiming to agitate the liquid and prevent sedimentation.
[0004] However, existing mixing devices use a single mixing shaft to drive the blades to rotate in one direction. This causes the pesticide solution to form a fixed circulation trajectory during mixing, making it difficult for the pesticide and water to mix fully. Some pesticides tend to settle or clump at the bottom of the tank, resulting in differences in the concentration of the sprayed solution and thus affecting the control of pests and diseases. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a wheat planting spraying device, which aims to improve the problem that the existing stirring device uses a single stirring shaft to drive the blades to rotate in one direction, which makes it difficult for pesticides and water to mix fully, resulting in differences in the concentration of the sprayed solution and thus affecting the control effect of pests and diseases.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wheat planting spraying device, including a spraying cart, a support frame and a water pump are fixedly connected to the upper surface of the spraying cart, a water tank is fixedly connected to the upper surface of the support frame, a feed pipe is fixedly connected to the upper surface of the water tank, a water pipe is provided at the input end of the water pump, one end of the water pipe is fixedly connected to the outer wall of the water tank, a water pipe is provided at the output end of the water pump, a plurality of nozzles are fixedly connected to the outer wall of the water pipe, and a stirring assembly is provided on the inner wall of the water tank; The stirring assembly includes a drive shaft and a sleeve shaft.

A geared disc is fixedly connected to one end of the sleeve shaft, and a stirring blade is fixedly connected to the other end of the sleeve shaft. A bracket is fixedly connected to the upper surface of the water tank, and a motor is fixedly connected to the upper surface of the bracket. The output end of the motor is fixedly connected to one end of the drive shaft. A rotating shaft is rotatably connected to the inner wall of the bracket. A gear is fixedly connected to the outer wall of the rotating shaft. The upper tooth end of the gear meshes with the tooth end of the geared disc, and the lower tooth end of the gear meshes with the tooth end of the geared disc.
[0007] Furthermore, a ball bearing is fixedly connected to the outer wall of the drive shaft, and the outer wall of the ball bearing is fixedly connected to the inner wall of the sleeve shaft.
[0008] Furthermore, a support plate is fixedly connected to one side of the outer wall of the spraying vehicle, a fixing block is fixedly connected to one side of the outer wall of the support plate, a threaded rod is rotatably connected to the inner wall of the fixing block, and a handle is fixedly connected to one end of the threaded rod.
[0009] Furthermore, a slider is threadedly connected to the outer wall of the threaded rod, and a mounting plate is fixedly connected to one side of the outer wall of the slider.
[0010] Furthermore, a slide rail is fixedly connected to one side of the outer wall of the support plate, and a second slider is slidably connected to the outer wall of the slide rail. One side of the outer wall of the second slider is fixedly connected to one side of the outer wall of the mounting plate.
[0011] Furthermore, a hinge is fixedly connected to one side of the outer wall of the mounting plate, and a rotating plate is fixedly connected to one side of the outer wall of the hinge. The lower surface of the rotating plate is fixedly connected to the upper surface of the nozzle.
[0012] Furthermore, an arc-shaped block is fixedly connected to the upper surface of the rotating plate, and an arc-shaped guide rail is fixedly connected to one side of the outer wall of the mounting plate.

[0013] Furthermore, the outer wall of the arc-shaped block is provided with a bolt, the outer wall of the bolt is provided on the inner wall of the arc-shaped guide rail, and one end of the bolt is threaded with a nut.
[0014] This utility model has the following beneficial effects: In this invention, the transmission shaft is driven by a motor to rotate, which in turn drives the first gear disc and the second stirring blade to rotate synchronously. At the same time, the first gear disc drives the gear to rotate, thereby driving the second gear disc to rotate in the opposite direction to the first gear disc. This, in turn, drives the sleeve shaft and the first stirring blade to rotate in the opposite direction. Compared with stirring in one direction, the simultaneous and opposite rotation of the first and second stirring blades in the tank allows for stronger convection and shearing motion of the pesticide solution at different locations in the tank. This improves the uniformity of pesticide and water mixing, prevents pesticide sedimentation or clumping, ensures consistent concentration of the sprayed solution, enhances the pest and disease control effect, and thus improves the practicality of the device.
[0015] In this invention, the sliding block moves along the axial direction of the threaded rod by rotating the threaded rod, thereby driving the mounting plate and the nozzle to rise and fall, adapting to different growth heights of wheat. By loosening the nut, the rotating plate is turned, causing the nozzle and the arc-shaped block to rotate together. After adjusting to the required angle, the nut is tightened again to fix the spray angle of the nozzle. The height and angle of the nozzle are adjustable to achieve precise coverage of the plants, reduce pesticide drift and waste, improve the control effect and operational flexibility, and thus improve the practicality of the device.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1-4This utility model provides an embodiment of a wheat planting spraying device, including a spraying cart 1 that serves as a mobile carrier, carrying a water tank 3 and a spraying system. A support frame 2 and a water pump 15 are fixedly connected to the upper surface of the spraying cart 1. A water tank 3 for storing a mixture of water and pesticide is fixedly connected to the upper surface of the support frame 2. A feed pipe 4 is fixedly connected to the upper surface of the water tank 3. A water pipe 16 connecting the water pump 15 and the water tank 3 is provided at the input end of the water pump 15. One end of the water pipe 16 is fixedly connected to the outer wall of the water tank 3. A water pipe 17 connecting the water pump 15 and a nozzle 18 is provided at the output end of the water pump 15. Multiple nozzles 18 for atomizing the pesticide solution transported by the water pipe 17 and spraying it onto the wheat plants are fixedly connected to the outer wall of the water pipe 17. A stirring assembly is provided on the inner wall of the water tank 3. The stirring assembly includes a drive shaft 5 and a sleeve shaft 6. The drive shaft 5 transmits power from the motor 12 to drive the gear disc 7 and the stirring blade 14 to rotate. The sleeve shaft 6 drives the stirring blade 13 to rotate. The drive shaft 5 and the sleeve shaft 6 are rotatably connected inside the water tank 3. A ball bearing 33 is fixedly connected to the outer wall of the drive shaft 5. The ball bearing 33 is used to connect the drive shaft 5 and the sleeve shaft 6 and reduce frictional resistance, so that the bidirectional rotational motion is independent and does not interfere with each other, thereby improving the stirring efficiency. The outer wall of the ball bearing 33 is fixedly connected to the inner wall of the sleeve shaft 6. A gear disc 7 is fixedly connected to one end of the drive shaft 5, and a stirring blade 14 is fixedly connected to the other end of the drive shaft 5. A gear disc 8 is fixedly connected to one end of the sleeve shaft 6, and the other end of the sleeve shaft 6 is fixedly connected to the other end of the sleeve shaft 6. A stirring blade 13 is fixedly connected. A bracket 11 is fixedly connected to the upper surface of the water tank 3. A rotating shaft 10 for supporting the rotation of gear 9 is rotatably connected to the inner wall of the bracket 11. A gear 9 for transmitting power from gear disc 7 to gear disc 8 is fixedly connected to the outer wall of the rotating shaft 10. The upper tooth end of gear 9 meshes with the tooth end of gear disc 7, and the lower tooth end of gear 9 meshes with the tooth end of gear disc 8. A motor 12 is fixedly connected to the upper surface of the bracket 11. The output end of the motor 12 is fixedly connected to one end of the transmission shaft 5.
[0020] Specifically, the water pump 15 draws the uniformly mixed pesticide solution from the water tank 3 through the water pipe 16. The water pump 15 then delivers the pesticide solution to multiple nozzles 18 for atomization and spraying through the water pipe 17. The gear 9, in conjunction with the gear disc 7 and the gear disc 8, drives the rotation. The upper part of the gear 9 meshes with the gear disc 7, and the lower part of the gear 9 meshes with the gear disc 8. Driven by the gear disc 7, the gear 9 rotates and drives the gear disc 8 to rotate in the opposite direction. This achieves the effect of the stirring blades 13 and 14 rotating in opposite directions, allowing the pesticide solution at different locations in the water tank 3 to generate stronger convection and shearing motion, greatly improving the uniformity of pesticide and water mixing, preventing pesticide sedimentation, ensuring consistent concentration of the sprayed pesticide solution, and improving the control effect of pests and diseases.
[0021] Reference Figure 5 and Figure 6A support plate 20 is fixedly connected to one side of the outer wall of the spraying vehicle 1. A fixing block 21 is fixedly connected to one side of the outer wall of the support plate 20. The fixing block 21 is a bearing for mounting a threaded rod 22. A threaded rod 22 for converting rotational motion into linear displacement of slider 1 23 is rotatably connected to the inner wall of the fixing block 21. A handle 32 is fixedly connected to one end of the threaded rod 22 for manually rotating and driving the threaded rod 22. A slider 1 23 is threadedly connected to the outer wall of the threaded rod 22. A mounting plate 26 is fixedly connected to one side of the outer wall of slider 1 23 for supporting the nozzle 18 and the angle adjustment structure. A slide rail 24 for guiding the vertical movement of slider 25 is fixedly connected to one side of the outer wall of the support plate 20. Sliding slider 25 is slidably connected to the outer wall of the slide rail 24. 5. One side of the outer wall is fixedly connected to the outer wall of the mounting plate 26. A hinge 27 for providing the pitch and rotation fulcrum of the nozzle 18 is fixedly connected to the outer wall of the mounting plate 26. A rotating plate 19 is fixedly connected to the outer wall of the hinge 27. The lower surface of the rotating plate 19 is fixedly connected to the upper surface of the nozzle 18. An arc-shaped block 28 for sliding and positioning the angle within the arc-shaped guide rail 30 is fixedly connected to the upper surface of the rotating plate 19. An arc-shaped guide rail 30 is fixedly connected to the outer wall of the mounting plate 26. The outer wall of the arc-shaped block 28 is slidably connected to the inner wall of the mounting plate 26. A bolt 29 is provided on the outer wall of the arc-shaped block 28. The outer wall of the bolt 29 is provided on the inner wall of the arc-shaped guide rail 30. A nut 31 is threadedly connected to one end of the bolt 29. The nut 31 is used to lock the bolt 29, thereby fixing the angle of the nozzle 18.
[0022] Specifically, the rotating motion of the handle 32 in conjunction with the threaded rod 22 causes the slider 23, which is threadedly connected to the threaded rod 22, to move axially along the threaded rod 22. Simultaneously, the slider 25 slides along the slide rail 24, guiding the movement of the mounting plate 26. Together, they drive the mounting plate 26 and the nozzle 18 to move up and down, achieving the effect of adjusting the height of the nozzle 18 to suit different wheat growth heights. The rotating plate 19, in conjunction with the hinge 27, performs a pitching and rotating motion, causing the arc-shaped block 28 to slide along the arc-shaped guide rail 30. After the angle is adjusted to the correct position, bolt 29 and nut 31 engage in a locking motion, fixing arc block 28 onto arc guide rail 30. This achieves the goal of fixing the angle of rotating plate 19 and nozzle 18 to adapt to different wheat planting densities. When the planting density is high, the angle of nozzle 18 is increased to allow the pesticide to penetrate the upper leaves and cover the middle and lower stems and leaves that are susceptible to pests and diseases. When the planting density is low, the angle is decreased to expand the spraying range of a single nozzle 18, reduce the number of nozzles required, and prevent the pesticide from drifting to non-target areas, making the pesticide coverage more precise.
[0023] Working principle: When spraying pesticides on wheat fields, water and pesticide solution are first added to water tank 3 through feed pipe 4. Then, motor 12 is started to drive drive shaft 5 to rotate. Drive shaft 5 drives toothed disc 7 and stirring blade 14 to rotate synchronously. At the same time, toothed disc 7 drives gear 9 to rotate. Through the rotation of gear 9, toothed disc 8 is driven to rotate in the opposite direction to toothed disc 7, which in turn drives sleeve shaft 6 and stirring blade 13 to rotate in the opposite direction. Through the simultaneous and opposite rotation of stirring blade 13 and stirring blade 14 in the tank, strong convection and shear force are formed, which realizes the full and rapid mixing and dissolution of pesticide solution, effectively preventing sedimentation and clumping, and ensuring uniform pesticide concentration. After the mixing is completed, water pump 15 is started. Water pump 15 draws the uniformly mixed pesticide solution from water tank 3 through water pipe 16, and then delivers it to multiple nozzles 18 through water pipe 2 17. The nozzles 18 atomize the pesticide solution and spray it onto the wheat plants to achieve pest and disease control. Secondly, the equipment can be adapted to different operational needs by adjusting the relevant structure of the nozzle 18. When the height of the nozzle 18 needs to be adjusted, the handle 32 can be rotated. The handle 32 drives the threaded rod 22 to rotate on the inner wall of the fixed block 21. Since the threaded rod 22 is threadedly connected to the slider 23, and one side of the slider 23 slides with the slide rail 24 through the mounting plate 26 and the second slider 25, the rotation of the threaded rod 22 will cause the slider 23 to move axially along the threaded rod 22, thereby driving the mounting plate 26 and the nozzle 18 to rise. To accommodate different growth heights of wheat, when the angle of the nozzle 18 needs to be adjusted, the nut 31 can be loosened first, and then the rotating plate 19 can be turned to rotate around the axis of the hinge 27. The rotating plate 19 drives the nozzle 18 and the arc block 28 to rotate together, thereby allowing the arc block 28 to slide along the arc guide rail 30. After adjusting to the required angle, the nut 31 is tightened again, and the arc block 28 is firmly locked on the arc guide rail 30 by the bolt 29 and the nut 31, thereby fixing the spray angle of the nozzle 18.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
