Description

Technical Field

[0001] The utility model relates to the technical field of helicopter medicine spraying devices, in particular to a helicopter medicine spraying filtering device. Background Art

[0002] In the vast scene of grassland pest control, helicopters have become an indispensable tool due to their efficient and fast operation capabilities. However, for the special environment of grassland, the uniformity, efficiency and safety of pesticide spraying are particularly important. The grassland is vast, the terrain is complex and changeable, and the distribution of pests and diseases is often uneven. This requires spraying equipment to not only have a strong spraying ability, but also be able to flexibly adjust the spraying direction and angle to ensure that the pesticide can accurately cover the target area while protecting non-target areas from unnecessary pollution.

[0003] A patent document with an existing patent announcement number of CN219961774U records an external pesticide sprayer for a helicopter. When in use, liquid medicine is added to the inner cavity of a collecting barrel through a drug adding pipe, and then a pressurizing component pressurizes the liquid medicine in the collecting barrel. The liquid medicine in the collecting barrel enters the spraying pipe through a drug discharge port, and then enters the drug outlet pipe through the spraying pipe. As the pressurizing component continues to perform the pressurizing operation, the baffle at the bottom of the drug outlet pipe is pushed open, thereby achieving the spraying of pesticides to all sides. At this time, the telescopic component is stretched. Since the telescopic component is located at both ends of the drug outlet pipe, the telescopic component is not easily exposed to the liquid medicine, thereby extending the service life of the telescopic component.

[0004] However, due to the changeable wind direction and undulating terrain of the grassland, the fixed spraying direction of the sprayer is often difficult to achieve the ideal prevention and control effect, and may cause waste of pesticide resources and environmental pollution.

[0005] Based on this, a helicopter spray medicine filtering device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

Detailed Embodiment

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, as Figures 1 - 4 shown, a helicopter spraying filtering device includes a liquid medicine tank 11. A filtering tank 12 is fixedly installed at the front end of the liquid medicine tank 11. A medicine passing port 19 is provided to connect the interior of the filtering tank 12 and the liquid medicine tank 11. A medicine inlet hopper 13 is fixedly installed at the upper end of the filtering tank 12. A cover plate 14 is hingedly installed at the upper end of the medicine inlet hopper 13. The liquid medicine tank 11 is fixedly installed at the upper end of a bottom plate 25. An adjusting box 31 is fixedly installed at the bottom end of the bottom plate 25. A spraying pipe 37 is provided at the bottom end of the adjusting box 31. The liquid medicine tank 11 is connected to the interior of the spraying pipe 37 through a medicine outlet pipe 36. The medicine outlet pipe 36 is rotatably connected to the liquid medicine tank 11 and fixedly connected to the spraying pipe 37. A plurality of atomizing nozzles 38 are fixedly arranged at equal intervals at the bottom end of the spraying pipe 37;

[0030] An electric push rod 20 is installed at the upper end of the liquid medicine tank 11. The telescopic end of the electric push rod 20 extends into the liquid medicine tank 11 and is fixedly connected to a pressing plate 21;

[0031] It further includes an adjusting structure which is arranged inside the adjusting box 31 and is used to adjust the spraying direction of the atomizing nozzles 38 fixed at the bottom end of the spraying pipe 37;

[0032] A filtering structure which is arranged inside the filtering tank 12 and is used to filter the liquid medicine.

[0033] In this embodiment, first, by opening the cover plate 14 at the upper end of the medicine inlet hopper 13, the liquid medicine to be sprayed is poured into the medicine inlet hopper 13; the liquid medicine enters the filtering tank 12. Under the action of the filtering structure, impurities in the liquid medicine are filtered out to ensure that the liquid medicine entering the liquid medicine tank 11 is pure and free of impurities; the filtered liquid medicine flows into the liquid medicine tank 11 through the medicine passing port 19 for storage.

[0034] The liquid medicine tank 11 is used to store the filtered liquid medicine; when spraying is required, the electric push rod 20 is started, and its telescopic end drives the pressing plate 21 to move downward inside the liquid medicine tank 11 to compress the liquid medicine, increasing the pressure of the liquid medicine to facilitate the transportation of the liquid medicine.

[0035] Under the action of the liquid medicine pressure, the liquid medicine is transported to the spraying pipe 37 through the medicine outlet pipe 36; the spraying pipe 37 is located inside the adjusting box 31. The spraying direction of the spraying pipe 37 and the atomizing nozzles 38 at its bottom end can be adjusted through the adjusting structure to meet different spraying requirements.

[0036] After the liquid medicine reaches the spraying pipe 37, it is sprayed out through a number of atomizing nozzles 38 fixedly arranged at equal intervals at the bottom end of the spraying pipe 37; the atomizing nozzles 38 spray the liquid medicine into fine droplets, improving the spraying effect, covering a wider area, and at the same time reducing the loss and waste of the liquid medicine.

[0037] In one embodiment, as Figures 3 - 4 shown, the adjusting structure includes a driving wheel 33, a transmission belt 34, and a driven wheel 35. The driving wheel 33, the transmission belt 34, and the driven wheel 35 are arranged inside the adjusting box 31. The driving wheel 33 is drivingly connected to the driven wheel 35 through the transmission belt 34. The driven wheel 35 is fixedly connected to the outer wall of the medicine outlet pipe 36. The upper end of the driving wheel 33 is fixedly connected to the output end of the motor 32, and the motor 32 is installed at the rear side of the upper end of the bottom plate 25.

[0038] The motor 32 drives the driving wheel 33 to rotate, and then drives the driven wheel 35 to rotate through the transmission belt 34. The rotation of the driven wheel 35 will drive the medicine outlet pipe 36 and the spraying pipe 37 fixedly connected thereto to rotate, thereby realizing the adjustment of the spraying direction of the atomizing nozzles 38.

[0039] In one embodiment, as Figure 3 shown, the filtering structure includes a sliding groove 15. The sliding groove 15 is opened on the inner wall of the filtering box 12. A through hole is opened at the front end of the sliding groove 15, and the through hole corresponds to the position of the sliding groove 15. A filter plate 16 is slidably installed inside the sliding groove 15. The front end of the filter plate 16 passes through the through hole and extends to the front end of the filtering box 12 and is fixedly connected to a fixing plate 17.

[0040] Through the filtering action of the filter plate 16, it can be ensured that the liquid medicine entering the liquid medicine tank 11 is pure and free of impurities, avoiding blockage or damage to the spraying system caused by impurities. When a certain amount of impurities accumulates on the filter plate 16, it can be conveniently taken out for cleaning or replacement to ensure the continuity and stability of the filtering effect.

[0041] In one embodiment, as Figures 1 - 3 shown, a pull handle is fixedly installed at the front end of the fixing plate 17.

[0042] The design of the pull handle enables the user to easily grasp and operate the fixing plate 17, and thus control the filter plate 16 connected thereto. The user only needs to simply pull the pull handle to realize the disassembly or installation of the filter plate 16, improving the convenience of operation.

[0043] In one embodiment, as Figure 3 shown, an inclined block 18 is installed at the inner bottom of the filtering box 12, and the lowest end of the inclined block 18 corresponds to the position of the medicine passing port 19.

[0044] The design of the inclined block 18 enables the liquid medicine in the filter box 12 to flow smoothly along its inclined plane under the action of gravity. This flow pattern helps to reduce the accumulation and retention of the liquid medicine at the bottom of the filter box. The lowest end of the inclined block 18 corresponds to the position of the medicine passage port 19, enabling the liquid medicine to enter the interior of the liquid medicine tank 11 more quickly through the medicine passage port 19.

[0045] In one embodiment, as Figures 1 - 2 shown, connecting frames 22 are symmetrically and fixedly arranged on the outer walls of the left and right sides of the liquid medicine tank 11. The upper ends of the connecting frames 22 are fixedly connected to lifting blocks 23, and a lifting opening 24 is formed through one end of the lifting block 23.

[0046] The design of the lifting block 23 and its lifting opening 24 enables the entire liquid medicine tank 11 to be safely and conveniently lifted by lifting equipment (such as a lifting chain, etc.) on a helicopter. This greatly simplifies the installation process of the liquid medicine tank on the helicopter and improves the installation efficiency.

[0047] In one embodiment, as Figures 1 - 3 shown, bottom frames 26 are symmetrically and fixedly arranged at the left and right sides of the bottom end of the bottom plate 25. A first support plate 27 is fixedly installed at the bottom end of the bottom frame 26. A plurality of damping springs 28 and dampers 29 are fixedly installed at the lower end of the first support plate 27. The damper 29 is arranged inside the damping spring 28, and the lower ends of the damping spring 28 and the damper 29 are fixedly connected to a second support plate 30.

[0048] The symmetric design of the bottom frames 26 is also beneficial for smoothly placing the liquid medicine tank 11 on the ground for the medicine adding operation. The operator can easily approach the liquid medicine tank 11 to add and inspect the liquid medicine, improving the operation efficiency. By arranging the damping springs 28 and the dampers 29 between the first support plate 27 and the second support plate 30, the vibration and impact from the helicopter or the ground are absorbed and dispersed, preventing the device from being damaged when the helicopter lands.

[0049] In one embodiment, as Figures 1 - 3 shown, a rubber soft pad is arranged at the bottom end of the second support plate 30, and anti-slip lines are arranged on the surface of the rubber soft pad.

[0050] The anti-slip lines on the surface of the rubber soft pad can increase the friction with the ground or other supporting surfaces, preventing the liquid medicine tank 11 from sliding or shifting during the medicine adding process, thereby causing the liquid medicine to spill.

[0051] The above embodiment discloses a helicopter spraying and filtering device. Among them, the cover plate 14 at the upper end of the medicine inlet hopper 13 is opened, and the liquid medicine to be sprayed is poured into the medicine inlet hopper 13; the liquid medicine enters the filter box 12, and through the filtering action of the filter plate 16, the impurities in the liquid medicine are filtered out to ensure that the liquid medicine entering the liquid medicine tank 11 is pure and free of impurities; the filtered liquid medicine flows into the liquid medicine tank 11 through the medicine passage port 19 for storage.

[0052] When spraying is required, the electric push rod 20 is activated, and its telescopic end drives the pressing plate 21 to move downward inside the liquid medicine tank 11 to compress the liquid medicine and increase the pressure of the liquid medicine; under the action of the liquid medicine pressure, the liquid medicine is transported to the spraying pipe 37 through the liquid medicine outlet pipe 36.

[0053] The spraying pipe 37 is located inside the adjustment box 31, and the spraying direction of the spraying pipe 37 and the atomizing nozzle 38 at its bottom end can be adjusted through an adjustment structure (such as the driving wheel 33, the transmission belt 34, and the driven wheel 35). The motor 32 drives the driving wheel 33 to rotate, and drives the driven wheel 35 to rotate through the transmission belt 34, thereby driving the spraying pipe 37 and the atomizing nozzle 38 to rotate to the required direction.

[0054] After the liquid medicine reaches the spraying pipe 37, it is sprayed out through a number of atomizing nozzles 38 fixedly arranged at equal intervals at the bottom end of the spraying pipe 37; the atomizing nozzles 38 spray the liquid medicine into fine mist droplets, improving the spraying effect and covering a wider area.

[0055] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
