Description

Technical Field

[0001] This utility model relates to the field of pesticide application device technology, specifically an adjustable height spraying pesticide application device. Background Technology

[0002] Goji berries are perennial woody plants belonging to the genus Lycium in the Solanaceae family. They are also known as Ningxia goji berries or Chinese goji berries. Their branches are slender and curved in an arch shape, and their leaves are ovate. They bloom in summer and bear red, ovate berries in autumn. They are mainly distributed in Northwest China, with Ningxia producing the most famous varieties.

[0003] In the process of controlling pests and diseases in wolfberry, an adjustable-height spraying device is required. Most existing spraying devices lack a structure for effectively mixing pesticide and water in a precise ratio. Therefore, workers must manually prepare the pesticide and water according to the required proportions before application, reducing spraying efficiency and control effectiveness, and increasing the workload of workers. Furthermore, existing spraying devices lack an effective stirring mechanism, leading to sedimentation after prolonged standing of the pesticide solution. This affects the normal use of the solution, reducing the overall practicality of the device and impacting the control effect.

[0004] Comparing with patent CN220777166U, an adjustable spraying device includes an adjustment component. The adjustment component includes a support frame, a mounting rod, a nozzle, a mounting base, an electric push rod, a fixed base, a lifting frame, a lifting base, two guide rods, a lead screw, a drive motor, a reduction motor, and a rotating shaft. By pushing the mounting base with the electric push rod, the angle of the nozzle can be finely adjusted without changing the height of the nozzle. This allows for convenient adjustment of the nozzle's height and angle according to the different heights of the plants.

[0005] Existing technologies can adjust the height and angle of the nozzle, but when mixing the liquid medicine with water, manual quantitative processing is still required. Furthermore, existing technologies do not have an effective stirring structure, which makes the liquid medicine prone to sedimentation and affects the normal use effect.

[0006] Based on this, an adjustable height spraying device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0033] 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.

[0034] In one embodiment, such as Figures 1-5 As shown, an adjustable height spraying device includes a movable base 1, a dosing cylinder 2 is provided above the movable base 1, a support frame 3 is symmetrically installed on the upper surface of the movable base 1, a feed cylinder 4 is fixedly installed inside the support frame 3, and the bottom of the feed cylinder 4 is connected to the upper surface of the dosing cylinder 2 through a solenoid valve 5 and a bellows 6.

[0035] A metering component is installed on the outer wall of the dosing cylinder 2 and is used to meter the drug solution and water.

[0036] A mixing assembly is installed on the upper surface of the dosing cylinder 2 and is used to mix the drug solution with water;

[0037] A spraying assembly is installed on the upper surface of the movable base 1 and is used to spray pesticides on goji berries;

[0038] An adjustment component is mounted on the upper surface of the movable base 1 and is used to adjust the spraying height of the spraying component.

[0039] In this embodiment, when spraying wolfberries, the pesticide solution is first added to the feed cylinder 4, and then water is added to the dosing cylinder 2. When the water enters the dosing cylinder 2, its weight causes the cylinder to shift downwards. At this time, the metering component can effectively weigh the water. After the water is added, the solenoid valve 5 opens, and the pesticide solution in the feed cylinder 4 enters the dosing cylinder 2 through the bellows 6. When the pesticide solution enters the dosing cylinder 2, the metering component can also effectively weigh it. When the pesticide solution weight reaches the specified ratio, the metering component transmits a signal to the controller, which then controls the solenoid valve 5 to close. This process is convenient and effective. The system directly mixes the medicinal liquid and water without requiring manual weighing. Once both liquid and water are added, the mixing component starts operating, effectively mixing the liquid and water while preventing sedimentation. After mixing, the spraying component begins spraying the liquid onto the goji berries. By adjusting the component settings, the height of the spraying component can be adjusted, allowing the entire device to effectively spray goji berries at different heights, thus improving the overall practicality and flexibility of the system.

[0040] In one embodiment, such as Figure 3 and Figure 5As shown, the metering assembly includes a fixing ring 9 fixedly installed on the outer wall of the dosing cylinder 2. Multiple connecting brackets 10 are fixedly connected to the surface of the fixing ring 9. Multiple damping rods 23 are fixedly connected to the upper surface of the movable base 1. The telescopic ends of the damping rods 23 are fixedly connected to the bottom of the connecting brackets 10. A return spring 24 is sleeved on the outside of the damping rods 23, and the return spring 24 abuts against the connecting bracket 10 and the movable base 1. A lowering bracket 26 is fixedly installed between every two connecting brackets 10. A weighing sensor 27 is located directly below the lowering bracket 26, and the bottom of the weighing sensor 27 is fixedly connected to the upper surface of the movable base 1. When water enters the dosing cylinder 2, the water causes the dosing cylinder 2 to shift downwards. At this time, the dosing cylinder 2 will drive the fixing ring 9 and the connecting brackets 10 to move synchronously, and the connecting brackets 10 will then drive the lowering brackets 26 to move synchronously. When the bottom of the pressure frame 26 touches the upper surface of the weighing sensor 27, the weight of the water can be measured by the weighing sensor 27. After the water is added, the solenoid valve 5 opens, and the medicine will also enter the dosing cylinder 2. When the medicine enters the dosing cylinder 2, the weighing sensor 27 can also effectively measure the weight of the medicine. When the weight of the medicine reaches the standard ratio, the weighing sensor 27 will transmit a signal to the controller, and the controller will then control the solenoid valve 5 to close. At this time, the water and medicine can be effectively mixed. During the downward movement of the connecting frame 10, the damping rod 23 and the return spring 24 will be squeezed simultaneously. When the dosing cylinder 2 is emptied, the return spring 24 will reset, thereby driving the dosing cylinder 2 to reset synchronously, effectively improving the overall practicality of the device.

[0041] In one embodiment, such as Figure 3 and Figure 5 As shown, a first bellows cover 25 is fitted on the outside of each of the multiple damping rods 23. The two ends of the first bellows cover 25 are fixedly connected to the opposite side of the movable base 1 and the connecting frame 10, respectively. By setting the first bellows cover 25, the damping rods 23 and the return spring 24 can be effectively protected, thereby effectively extending the service life of the damping rods 23 and the return spring 24.

[0042] In one embodiment, such as Figure 3 As shown, the mixing assembly includes a first housing 11 fixedly connected to the upper surface of the dosing cylinder 2 for mounting a first motor 12. A rotating rod 13 is rotatably connected to the inner wall of the dosing cylinder 2. The rotating rod 13 is driven by the first motor 12. Multiple mixing rods 14 are fixedly connected to the outer wall of the rotating rod 13. When it is necessary to mix water and medicine, the first motor 12 starts to run, driving the rotating rod 13 to rotate synchronously. The rotating rod 13 then drives the mixing rods 14 to rotate synchronously. At this time, the medicine and water can be mixed through the mixing rods 14, while avoiding precipitation of the medicine.

[0043] In one embodiment, such as Figures 1-3 As shown, the spraying assembly includes a liquid pump 8 fixedly installed on the upper surface of the movable base 1. The inlet end of the liquid pump 8 is connected to the bottom of the dosing cylinder 2 through a pipe, and the outlet end of the liquid pump 8 is connected to an atomizing nozzle 7 through a pipe. When it is necessary to spray the goji berries, the liquid pump 8 starts to run. At this time, the liquid pump 8 will transfer the liquid in the dosing cylinder 2 to the atomizing nozzle 7, and then spray it out through the atomizing nozzle 7. At this time, the goji berries can be effectively sprayed.

[0044] In one embodiment, such as Figure 2 and Figure 4 As shown, the adjustment assembly includes an adjustment plate 15 fixedly connected to the upper surface of the movable base 1. A threaded rod 18 is rotatably connected to the inner wall of the adjustment plate 15. A second housing 16 for mounting a second motor 17 is fixedly connected to the upper surface of the adjustment plate 15. The threaded rod 18 is driven by the second motor 17. A threaded block 19 is driven to the outer wall of the threaded rod 18. A movable groove for the threaded block 19 to move is opened on the surface of the adjustment plate 15. The surface of the threaded block 19 is fixedly connected to the surface of the atomizing nozzle 7. When the height of the atomizing nozzle 7 needs to be adjusted, the second motor 17 starts to run. At this time, the second motor 17 will drive the threaded rod 18 to rotate synchronously, and the threaded block 19 will move synchronously on the outer wall of the threaded rod 18, driving the atomizing nozzle 7 to move synchronously. At this time, the height of the atomizing nozzle 7 can be adjusted, so that the goji berries of different heights can be sprayed.

[0045] In one embodiment, such as Figure 2 and Figure 4 As shown, a fixed sleeve 21 is symmetrically installed on the surface of the adjusting plate 15, and a sliding sleeve 20 is fixedly connected to the surface of the threaded block 19. The sliding sleeve 20 is slidably connected to the outer wall of the adjusting plate 15. A second bellows cover 22 is symmetrically installed on the surface of the sliding sleeve 20. The other end of the second bellows cover 22 is fixedly connected to the surface of the fixed sleeve 21. During the movement of the threaded block 19, the sliding sleeve 20 will also move synchronously. At this time, the sliding sleeve 20 will stretch or compress the second bellows cover 22 synchronously. Through the setting of the second bellows cover 22, the interior of the adjusting plate 15 can be effectively protected, thereby preventing dust and other impurities from entering the adjusting plate 15 and affecting the normal use of the threaded rod 18 and the threaded block 19.

[0046] In one embodiment, such as Figures 1-3As shown, multiple guide rods 28 are fixedly installed on the upper surface of the movable base 1. A limiting plate 29 is fixedly connected to the top of each pair of guide rods 28. A guide plate 30 is slidably connected to the outer wall of each pair of guide rods 28. The surface of the guide plate 30 is fixedly connected to the surface of the fixing ring 9. During the movement of the fixing ring 9, the guide plate 30 will also move synchronously on the outer wall of the guide rod 28. At this time, the guide plate 30 and the guide rod 28 can effectively limit and guide, thereby effectively improving the stability of the dosing cartridge 2 during the movement.

[0047] The above embodiment discloses an adjustable height spraying device. When spraying wolfberries, the pesticide solution is first added to the feed cylinder 4, and then water is added to the dosing cylinder 2. When water enters the dosing cylinder 2, its weight causes the cylinder to shift downwards. At this time, the weighing sensor 27 can effectively weigh the water quantitatively. After the water is added, the solenoid valve 5 opens, and the pesticide solution in the feed cylinder 4 enters the dosing cylinder 2 through the bellows 6. When the pesticide solution enters the dosing cylinder 2, the weighing sensor 27 can also effectively weigh the solution. When the solution weight reaches the specified ratio, the weighing sensor 27 transmits a signal to the controller, which then controls the solenoid valve 5 to close. This device allows for convenient and effective mixing of medicinal liquid and water without the need for manual weighing. Once both liquid and water are added, the first motor 12 starts running, and the mixing rod 14 mixes the liquid and water, preventing sedimentation. After mixing, the pump 8 starts running, and the atomizing nozzle 7 sprays the liquid onto the goji berries. The threaded rod 18 and threaded block 19 allow for effective height adjustment of the atomizing nozzle 7, enabling the device to effectively spray goji berries at different heights, thus improving its overall practicality and flexibility.
