Description

Technical Field

[0001] This utility model belongs to the field of pesticide tank technology for agricultural helicopters, specifically relating to a pesticide tank structure for agricultural helicopters. Background Technology

[0002] As research and application of helicopters across various industries continues, it is becoming increasingly apparent that helicopters play a significant role in all aspects of social production and daily life. Using modern, high-tech machinery not only improves work efficiency and quality and reduces operating costs, but also lowers the risks to personnel and protects life and property. Agricultural helicopters, in particular, offer numerous advantages over conventional plant protection machinery, with their operational efficiency being many times higher than that of elevated sprayers, currently the most efficient ground-based plant protection equipment.

[0003] Existing helicopter plant protection sprayers generally use a common box structure. During helicopter flight, the pesticide in the sprayer may settle, causing a difference in concentration between the upper and lower layers of pesticide solution, which affects the control effect on pests and diseases. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed medicine box structure for agricultural plant protection helicopters in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A medicine box structure for an agricultural plant protection helicopter includes a U-shaped medicine box body. A connecting structure for fixing the medicine box body to the helicopter is provided on the upper surface of the middle section of the medicine box body. Two stirring shafts are symmetrically arranged along the length of the medicine box body. The ends of the stirring shafts penetrate the side wall of the medicine box body and are rotatably connected to the side wall of the medicine box body through sealed bearings. Multiple stirring rods are installed on a section of the stirring shaft located in the inner cavity of the medicine box body. A fan blade is fixedly connected to the end of the stirring shaft near the front of the helicopter. An air collecting shroud is sleeved on the outside of the fan blade. A connecting sleeve is fixedly connected to the end of the air collecting shroud near the outer wall of the medicine box body. Multiple exhaust holes are opened around the periphery of the connecting sleeve.

[0007] As a further optimization of this utility model, the top of the medicine box body is fixedly connected to an injection nozzle whose bottom end communicates with the inner cavity of the medicine box body. The injection nozzle has an external thread on one end located outside the medicine box body, and a sealing cap is screwed to the top of the injection nozzle through the external thread.

[0008] As a further optimization of this utility model, the connection structure includes a connecting frame fixedly installed on the upper surface of the middle section of the medicine box body. Four screws are matrix-installed on the connecting frame, and the top of the screws is connected and fixed to the helicopter with an external nut.

[0009] As a further optimization of this utility model, a spray pipe with its top end communicating with the inside of the medicine tank body is installed on the bottom wall of the medicine tank body. A solenoid valve is installed at the connection between the spray pipe and the bottom wall of the medicine tank body. A nozzle is fixedly connected to the bottom end of the spray pipe.

[0010] As a further optimization of this utility model, a partition plate for dividing the medicine tank body into two chambers is fixedly installed inside the medicine tank body between the two stirring shafts. The periphery of the partition plate is fixed to the inner wall of the medicine tank body, and a connecting hole for connecting the two chambers is opened at the bottom of the partition plate.

[0011] As a further optimization of this utility model, the wind collector shroud has a cylindrical structure, with a gap between the inner wall of the wind collector shroud and the end of the fan blade, and the inner diameter of the wind collector shroud gradually increases from the end near the connecting sleeve to the end away from the connecting sleeve.

[0012] The beneficial effects of this utility model are as follows: During the high-speed flight of the helicopter carrying the medicine box body, since the fan blades are installed at the front of the helicopter, the high-speed airflow can be collected by the air collector and act on the fan blades, driving the fan blades to rotate, thereby driving the stirring shaft fixedly connected to the end of the fan blades to rotate. During the rotation of the stirring shaft, the stirring rod rotates inside the medicine box body 1 to stir the medicine liquid inside the medicine box body, so as to avoid the precipitation of medicine in the medicine liquid and the problem of uneven concentration of medicine liquid in the upper and lower layers of the medicine box body.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a medicine box structure for an agricultural plant protection helicopter includes a U-shaped medicine box body 1. An injection nozzle 2 with its bottom end communicating with the inner cavity of the medicine box body 1 is fixedly connected to the top of the medicine box body 1. An external thread is provided on one end of the injection nozzle 2 located outside the medicine box body 1. A sealing cap 3 is screwed to the top of the injection nozzle 2 through the external thread. When in use, the sealing cap 3 is opened, and the prepared medicine solution can be added into the medicine box body 1 through the injection nozzle 2.

[0021] The upper surface of the middle section of the medicine box body 1 is provided with a connection structure for fixing the medicine box body 1 to the helicopter. The connection structure includes a connecting frame 4 fixedly installed on the upper surface of the middle section of the medicine box body 1. Four screws 5 are installed in a matrix on the connecting frame 4. The top of the screws 5 are connected and fixed to the helicopter with an external nut. When installing the medicine box body 1, the screws 5 are aligned with the holes opened on the connecting parts on the helicopter, and the top of the screws 5 are passed through the connecting parts of the helicopter. Then, the bolts are screwed onto the screws 5 above the connecting parts to complete the installation of the medicine box body 1.

[0022] A spray pipe 6 with its top end connected to the inside of the medicine tank body 1 is installed on the bottom wall of the medicine tank body 1. A solenoid valve 8 is installed at the connection between the spray pipe 6 and the bottom wall of the medicine tank body 1. A nozzle 7 is fixedly connected to the bottom end of the spray pipe 6. The spray pipe 6 is set to discharge the medicine liquid stored in the medicine tank body 1. When the helicopter flies over the plant that needs to be sprayed, the solenoid valve 8 can be opened, so that the medicine liquid in the medicine tank body 1 falls along the spray pipe 6 under its own gravity, and is finally evenly sprayed on the plant through the nozzle 7 installed at the bottom end of the spray pipe 6.

[0023] Two stirring shafts 11 are symmetrically arranged inside the main body 1 of the medicine box along its length. The ends of the stirring shafts 11 penetrate the side wall of the main body 1 of the medicine box and are rotatably connected to the side wall of the main body 1 of the medicine box through a sealed bearing 12. The sealed bearing 12 can not only reduce the resistance when the stirring shaft 11 rotates, but also seal the connection between the stirring shaft 11 and the side wall of the main body 1 of the medicine box through the sealed bearing 12, so as to avoid leakage of medicine liquid as much as possible.

[0024] A partition 9 is fixedly installed inside the main body 1 of the medicine tank between the two stirring shafts 11 to divide the main body 1 of the medicine tank into two chambers. The periphery of the partition 9 is fixed to the inner wall of the main body 1 of the medicine tank, and a connecting hole 10 is opened at the bottom of the partition 9 to connect the two chambers. The partition 9 is set to divide the inner cavity of the main body 1 of the medicine tank into two chambers, so that the liquid medicine in the two chambers can only communicate with each other through the connecting hole 10, so as to avoid the problem that the liquid medicine in the main body 1 of the medicine tank will shake and vibrate wildly and oscillate when the helicopter changes its flight state, which would affect the flight of the helicopter.

[0025] Multiple stirring rods 13 are installed on a section of the stirring shaft 11 located inside the medicine tank body 1. A fan blade 14 is fixedly connected to the end of the stirring shaft 11 near the front of the helicopter. An air collecting shroud 15 is fitted on the outside of the fan blade 14. A connecting sleeve 16 is fixedly connected to the end of the air collecting shroud 15 near the outer wall of the medicine tank body 1. Multiple exhaust holes 17 are opened around the connecting sleeve 16. When the helicopter carries the medicine tank body 1 at high speed, since the fan blade 14 is installed on the side of the medicine tank body 1 near the front of the helicopter, the high-speed airflow can be collected by the air collecting shroud 15 and act on the fan blade 14, pushing the fan blade 14 to rotate, thereby driving the stirring shaft 11 fixedly connected to the end of the fan blade 14 to rotate. During the rotation of the stirring shaft 11, the stirring rods 13 rotate inside the medicine tank body 1 to stir the medicine liquid inside the medicine tank body 1, so as to avoid the precipitation of the medicine in the medicine liquid and the problem of uneven concentration of medicine liquid in the upper and lower layers inside the medicine tank body 1.

[0026] The air collector shroud 15 has a cylindrical structure. A gap is left between the inner wall of the air collector shroud 15 and the end of the fan blade 14 to minimize the impact between the fan blade 14 and the inner wall of the air collector shroud 15 during rotation, which could damage the fan blade 14. In addition, the inner diameter of the air collector shroud 15 gradually increases from the end near the connecting sleeve 16 to the end away from the connecting sleeve 16. This allows the flow of air entering the air collector shroud 15 to be affected by the change in the inner diameter of the air collector shroud 15, thereby further increasing the flow velocity of the air in the air collector shroud 15 and facilitating the rotation of the fan blade 14 by the high-speed flow of air.

[0027] It should be noted that the pesticide tank structure on this type of agricultural plant protection helicopter allows the mixed pesticide solution to be injected into the main body 1 of the tank through the injection nozzle 2 after opening the sealing cover 3. The helicopter can then carry the main body 1 of the tank to the plants that need to be sprayed. Then, the operator controls the solenoid valve 8 to open, causing the pesticide solution in the main body 1 to fall along the spray pipe 6 under its own gravity. Finally, it is evenly sprayed onto the plants through the nozzle 7 installed at the bottom of the spray pipe 6. Because the stirring shaft 11 is located in the inner cavity of the main body 1, multiple stirring rods 13 are installed on it. A fan blade 14 is fixedly connected to one end of the stirring shaft 11 near the front of the helicopter. When the helicopter is flying at high speed carrying the medicine tank body 1, the high-speed airflow can be collected by the air collector shroud 15 and act on the fan blade 14, pushing the fan blade 14 to rotate, thereby driving the stirring shaft 11, which is fixedly connected to the fan blade 14 at the end, to rotate. During the rotation of the stirring shaft 11, the stirring rod 13 rotates inside the medicine tank body 1 to stir the medicine liquid inside the medicine tank body 1, so as to avoid the precipitation of medicine in the medicine liquid and the problem of uneven concentration of medicine liquid in the upper and lower layers inside the medicine tank body 1.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
