[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To address the technical problem that existing spraying devices for mulberry planting have low pesticide spraying efficiency, can only spray one side at a time, and require time-consuming adjustments to the angle of the spraying equipment when spraying the other side of the trees, thus reducing spraying efficiency, this utility model provides a spraying device for mulberry planting that can achieve more uniform mixing of pesticide solution, improve spraying efficiency, and ensure uniform spraying of pesticide solution.

[0029] It should be noted that the spraying device for mulberry planting described in this utility model is used in, but not limited to, the field of mulberry planting. For ease of explanation, this utility model only uses the application of the spraying device for mulberry planting in the field of mulberry planting as an example for explanation. The principle of the spraying device for mulberry planting applied to other types of equipment is essentially the same as the principle applied to the field of mulberry planting, and will not be described in detail here.

[0030] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a spraying device for mulberry planting according to one embodiment of the present invention. A spraying device for mulberry planting includes:

[0031] Vehicle body 1;

[0032] The medicine preparation box 2 is installed on the vehicle body 1, and the medicine preparation box 2 is provided with a water inlet 21 and a water outlet 22, and the medicine preparation box 2 is provided with a recessed end.

[0033] The stirring mechanism 3 includes a power end 31, a transmission end 32 and a stirring end 33; the power end 31 is located outside the medicine dispensing box 2 and is connected to the stirring end 33 located inside the medicine dispensing box 2 through the transmission end 32, and is used to drive the stirring end 33 to operate.

[0034] The spraying mechanism 4 includes a liquid extraction end 41, a spraying end 42, and a height adjustment end 43. The liquid extraction end 41 is disposed on the medicine preparation tank 2, with one end extending into the medicine preparation tank 2 and the other end connected to the spraying ends 42 on both sides of the recessed end. The height adjustment end 43 is disposed on the medicine preparation tank 2 and is used to adjust the position and height of the spraying end 42.

[0035] In this embodiment, the device integrates the stirring and spraying of the medicine solution, making it easy to operate in the planting area and effectively improving the adaptability and portability of the equipment. The stirring mechanism 3 can continuously or periodically stir the medicine solution and water in the medicine tank 2 to prevent the solid components in the medicine solution from settling, thereby ensuring uniform concentration of the medicine solution. The spraying end 42 of the spraying mechanism 4 is set on both sides of the recessed end of the medicine tank 2, which can realize simultaneous spraying on both sides. The height adjustment end 43 can adjust the position of the spraying end 42 according to the actual spraying scenario, so as to adapt to mulberry trees at different growth stages and ensure that the equipment has stronger adaptability. Due to the wide spraying range and high efficiency, repetitive work can be reduced. In addition, the thorough stirring avoids the problem of overspraying or underspraying caused by uneven medicine solution, which helps to save medicine resources and reduce environmental pollution.

[0036] In one embodiment, please refer to Figures 1-4 To improve the mobility of the vehicle body 1, the lower end of the vehicle body 1 is provided with multiple moving wheels 11, and each moving wheel 11 is provided with a braking end 12. The braking end 12 includes a threaded rod 121, a threaded block 122 and a braking plate 123. The threaded rod 121 is provided on the vehicle body 1, and the threaded rod 121 is threadedly connected to the threaded block 122. The lower end of the threaded block 122 is connected to the braking plate 123 that cooperates with the moving wheel 11.

[0037] In this embodiment, the movable wheel 11 is installed at the bottom of the vehicle body 1 to support and allow the entire spraying device to move flexibly. The threaded rod 121 is fixed to the vehicle body 1 and arranged vertically. The threaded block 122 is threadedly connected to the threaded rod 121 and can move up and down along the threaded rod 121. The brake plate 123 is connected to the lower end of the threaded block 122 and faces the outer edge surface of the movable wheel 11. When it is necessary to position the spraying device or prevent it from sliding accidentally, the user rotates the threaded rod 121. The rotation of the threaded rod 121 drives the threaded block 122, which is threaded to it, to move downward. The threaded block 122 drives the brake plate 123 to move downward synchronously, so that it is close to the outer edge of the movable wheel 11. Friction is generated between the brake plate 123 and the movable wheel 11, thereby preventing the wheel from rotating and realizing mechanical braking. When it is necessary to release the brake, the threaded rod 121 is rotated in the opposite direction, so that the threaded block 122 moves upward. The device is lifted, causing the brake plate 123 to disengage from the moving wheel 11, allowing the moving wheel 11 to return to its free rotation state. The device can then be moved again. During field operations, especially on uneven terrain or slopes, the device is prone to displacement due to gravity or wind. The brake end 12 can be used to stabilize and fix the device before spraying begins, preventing accidents such as uneven spraying or equipment tipping due to accidental slippage. Each moving wheel 11 is equipped with an independent brake end 12, allowing users to selectively lock one side or all wheels according to the terrain. This is suitable for irregular terrain or positioning needs after turning, improving the flexibility and adaptability of the equipment. The manual adjustment structure is simple and reliable, with low maintenance costs. It does not require a complex hydraulic or electronic control system, making it easy to maintain and replace parts later. It can operate normally even in field environments without power or with inconvenient power supply.

[0038] In one embodiment, please refer to Figures 1-5To improve the stirring efficiency of the stirring mechanism 3, the power end 31 includes a motor 311 and a spiral stirring rod 312. The motor 311 is mounted on the vehicle body 1, and its output end passes through the medicine dispensing box 2 and is connected to the spiral stirring rod 312. The end of the spiral stirring rod 312 passes through the medicine dispensing box 2 and is connected to a transmission end 32. The transmission end 32 includes a first wheel body 321, a second wheel body 322, a tensioning wheel 323, and a transmission belt 324. The first wheel body 321 is mounted on the end of the spiral stirring rod 312, and the second wheel body 322 is located at the upper end of the first wheel body 321. A tensioning wheel 323 is located between the first wheel body 321 and the second wheel body 322. A transmission belt 324 is provided between the tensioning wheels 323. A transmission shaft 325 is connected to the second wheel body 322. A first bevel gear 326 is fixed to the end of the transmission shaft 325. A second bevel gear 327 meshes with the lower end of the first bevel gear 326. An agitation end 33 is connected to the lower end of the second bevel gear 327. The agitation end 33 includes an agitation shaft 331 and agitation blades 332. The agitation shaft 331 is connected to the lower end of the second bevel gear 327. One end of the agitation shaft 331 extends into the medicine tank 2. Multiple agitation blades 332 are connected to the outer periphery of the agitation shaft 331. A power supply block is also provided on the vehicle body 1. Adjustment valves are provided on the water inlet 21 and the water outlet 22. A push handle 5 is also installed on the vehicle body 1.

[0039] In this embodiment, the motor 311 is mounted on the vehicle body 1 to provide power. The spiral agitator 312 is connected to the output shaft of the motor 311, passes through the medicine dispensing box 2, and serves as the main drive shaft 325. The first wheel 321 is fixed to the end of the spiral agitator 312, and the second wheel 322 is located above the first wheel 321. The tension wheel 323 is used to adjust the tension of the transmission belt 324. The transmission belt 324 connects the two wheels and transmits power. The drive shaft 325 connects the second wheel 322 and the first bevel gear 326. The first bevel gear 326 is mounted at the end of the drive shaft 325, and the second bevel gear 327 meshes with the first bevel gear 326, outputting power in the vertical direction. The agitator shaft 331 is connected to the second bevel gear 327 and extends into the medicine dispensing box 2, agitating the blades. 332 is distributed around the stirring shaft 331 and is used to stir the medicine solution. The power supply block supplies power to the motor 311 and other electrical equipment. The regulating valve controls the flow of water in the inlet 21 and outlet 22. Pushing the handle 5 facilitates manual operation of the moving device. When the motor 311 starts, its output shaft drives the spiral stirring rod 312 to rotate. One end of the spiral stirring rod 312 is connected to the motor 311, and the other end extends to the outside of the medicine tank 2 and is connected to the first wheel body 321. The rotation of the first wheel body 321 drives the transmission belt 324 to move. The transmission belt 324 drives the second wheel body 322 above to rotate. The tensioning wheel 323 set between the two wheels can adjust the tension of the transmission belt 324 to prevent slippage. The second wheel body 322 transmits power through the transmission shaft 325. A first bevel gear 326 is fixed at the end of component 325, meshing with a second bevel gear 327 below. The first bevel gear 326 drives the second bevel gear 327 to rotate, changing the power direction from horizontal to vertical. The second bevel gear 327 is connected to a stirring shaft 331, driving it to rotate. The stirring shaft 331 extends into the mixing tank 2, with multiple stirring blades 332 arranged around its outer periphery. The stirring blades 332 rotate with the stirring shaft 331, forming a circulating liquid flow field within the mixing tank 2. This ensures thorough mixing of the pesticide components, prevents solid particles from settling or liquid from stratifying, improves the consistency of pesticide concentration during spraying, and ensures effective control. The use of a motor 311, belt drive, and bevel gear reversal effectively converts the power from horizontal to vertical. The system features tight interlocking, smooth transmission, and minimal energy loss, ensuring stable operation of the stirring blades 332 over extended periods. The spiral stirring rod 312 serves as the drive shaft, driving two pulleys. The bevel gear structure optimizes the spatial layout, allowing the stirring shaft 331 to penetrate deep into the bottom of the mixing tank 2. The pulley diameter ratio can be adjusted as needed to match different stirring speeds. Multiple stirring blades 332 are arranged in a ring around the stirring shaft 331, providing wide coverage and creating vortices in the pesticide solution to enhance stirring intensity. This prevents pesticide precipitation or excessively high local concentrations, improving spraying effectiveness. The entire stirring system can operate automatically, reducing manual intervention. Users only need to start the motor 311 to complete the stirring process, making it particularly suitable for continuous operation scenarios, such as large-scale mulberry planting areas.

[0040] In this embodiment, please refer to Figures 1-5 To improve the spraying effect of the equipment, the liquid extraction end 41 includes a water pump 411, a first conduit 412, and a second conduit 413. One end of the first conduit 412 extends into the dosing tank 2, and the end of the first conduit 412 is connected to the water pump 411. The outlet end of the water pump 411 is connected to the second conduit 413, and the end of the second conduit 413 is connected to the spraying end 42. The spraying end 42 includes a retractable hose 421, a spray housing 422, and several spray heads 423. The end of the second conduit 413 is connected to the retractable hose 421, and the end of the retractable hose 421 is connected to a diversion pipe inside the spray housing 422. Dry spray heads 423 are equidistantly arranged on the diversion pipe. The lower end of the spray shell 422 is connected to a height adjustment end 43. The height adjustment end 43 includes a column 431, a spring strip 4311, a sliding plate 432, and an electric telescopic rod 433. There are four columns 431, which are distributed in pairs on both sides of the recessed end. Each column 431 is provided with a spring strip 4311. A sliding plate 432 is provided on the column 431. The lower end of the sliding plate 432 is connected to the spring strip 4311. The spray shell 422 is connected to the sliding plate 432. The sliding plate 432 is connected to the telescopic end of the electric telescopic rod 433 through a connecting plate 4321.

[0041] In this embodiment, the water pump 411 provides power, the first conduit 412 connects the bottom of the medicine tank 2 to the inlet of the water pump 411, and the second conduit 413 connects the outlet of the water pump 411 to the spray end 42. A retractable hose 421 flexibly connects the second conduit 413 to the spray shell 422, which protects the internal structure. A distribution pipe is located inside the spray shell 422 to evenly distribute the medicine solution. Spray heads 423 are equidistantly arranged on the distribution pipe for uniform spraying. Four columns 431 are arranged in pairs on both sides of the recessed end, and spring strips 4311 are mounted on the columns 431 for sliding. The movable plate 432 provides cushioning, and the sliding plate 432 supports the spray shell 422 and slides up and down along the column 431. The electric telescopic rod 433 drives the sliding plate 432 to rise and fall, thereby adjusting the height of the spray shell 422. This allows the device to adjust the position of the spray end 42 according to the height of the mulberry tree, ensuring optimal spray coverage. When spraying is needed, the water pump 411 is started, drawing liquid medicine from the bottom of the medicine tank 2 through the first conduit 412. After being pressurized by the water pump 411, the liquid medicine is delivered to the spray end 42 through the second conduit 413. The end of the second conduit 413 is connected to a retractable hose 421, whose flexible structure allows the spray end 42 to maintain its position even when the height changes. A stable connection is established. The retractable hose 421 delivers the pesticide solution into the distribution pipe within the spray housing 422. The distribution pipe evenly distributes the solution to each spray head 423. Multiple spray heads 423 are equidistantly arranged to ensure consistent spray density and reduce dead zones. The spray heads 423 atomize the pesticide solution and spray it out, covering the canopy and both sides of the leaves of the mulberry tree. Depending on the height of the mulberry tree, the electric telescopic rod 433 is activated. The telescopic end of the electric telescopic rod 433 pushes or pulls the sliding plate 432 via the connecting plate 4321. The sliding plate 432 slides up and down along the column 431, causing the spray housing 422 to rise or fall. The spring strip 4311 acts as a shock absorber to prevent the spray head 422 from being damaged by the spring. To prevent damage from vibration or unstable spraying, the system achieves optimal distance control between the spray head 423 and the mulberry tree, improving spraying efficiency and coverage. It employs a water pump 411 and a multi-nozzle design to enable large-area simultaneous spraying, meeting the rapid operation needs of densely planted mulberry areas, increasing the sprayed area per unit time, and improving overall operational efficiency. Multiple equidistantly arranged spray heads 423, combined with a distribution pipe, ensure uniform pesticide distribution, reducing pesticide waste and missed spraying. This is beneficial for improving pest and disease control and reducing pesticide usage. With the help of an electric telescopic rod 433, the spraying height can be flexibly adjusted according to the mulberry tree's growth stage, such as the seedling stage or the mature tree stage.

[0042] To better understand this utility model, the following is combined with... Figures 1 to 5The technical solution of this utility model is described in detail as follows: The operator opens the regulating valve of the water inlet 21 on the mixing tank 2, injects clean water into the tank, adds pesticide powder or concentrate according to the ratio, closes the water inlet 21 valve, starts the stirring mechanism 3 to initially mix the pesticide solution, pushes the push handle 5, and moves the device to the mulberry planting area via the moving wheels 11. If it is a slope or uneven ground, the brake end 12 can be used to fix the vehicle body 1 after positioning, and the threaded rod 121 is rotated so that the threaded block 122 drives the brake plate 123 to press down and press it against the outside of the moving wheels 11. Friction is generated between the brake plate 123 and the wheel surface to prevent slippage. To release, the threaded rod 121 is rotated in the reverse direction. The motor 311 is then powered on, driving the spiral agitator 312 to rotate. The spiral agitator 312 transmits power to the agitator shaft 331 via the transmission end 32. The agitator shaft 331 drives multiple agitator blades 332 to rotate, creating a circulating flow within the mixing tank 2. This ensures sufficient suspension of solid components in the solution, preventing sedimentation and ensuring consistent spraying. The water pump 411 is then started, drawing water from the mixing tank 2 through the first conduit 412. The medicine tank 2 draws in the liquid medicine from the bottom. After being pressurized by the water pump 411, the liquid medicine is delivered to the spray end 42 through the second conduit 413. The liquid medicine enters the retractable hose 421 from the end of the second conduit 413. The retractable hose 421 delivers the liquid medicine into the distribution pipe inside the spray shell 422. The distribution pipe evenly distributes the liquid medicine to multiple equally spaced spray heads 423. The spray heads 423 atomize the liquid medicine and spray it out, covering the canopy and both sides of the leaves of the mulberry tree. According to the current height of the mulberry tree, the position of the spray end 42 is adjusted, and the electric telescopic rod 433 is activated. Its telescopic end is connected to... Plate 4321 drives sliding plate 432 to slide up and down along column 431. Sliding plate 432 drives spray shell 422 to rise or fall. Spring strip 4311 plays a buffering role to prevent vibration from affecting the spraying effect. Adjust to the optimal spraying height, usually slightly higher than the top of the mulberry tree by 10-20cm, to ensure that the liquid coverage is wide and uniform and to reduce waste. After spraying is completed, turn off the power to the water pump 411, motor 311 and other equipment. If you need to continue working, repeat the above process. If you finish working for the day, open the drain outlet 22 regulating valve to drain the remaining liquid.
