Abstract
Description
Technical Field
[0001] This application relates to the field of spraying device technology, and more specifically, to a spraying device for the prevention and control of forest pests and diseases. Background Technology
[0002] Pest and disease control is the human-made means taken to reduce or prevent damage to crops or livestock by pathogenic microorganisms and pests. It can generally be divided into chemical control using chemical substances such as insecticides and physical control using physical energy such as light or radiation, or by constructing barriers. In chemical control using insecticides, the insecticide and water are mixed and then sprayed onto the trees using a spraying device.
[0003] Existing technology publication CN219635481U discloses a drone-based pest control spraying device. By incorporating a fixing mechanism, the water tank of this drone-based pest control spraying device is more securely fixed, preventing displacement during flight spraying and thus avoiding flight safety issues. Compared to the traditional method of fixing the water tank with ropes, this invention is more reliable. Furthermore, the addition of a connecting plate and slider between the water tank and the base improves the efficiency of filling and installing the water tank. The spraying mechanism allows this drone-based pest control spraying device to better handle various geographical environments and aerial spraying tasks, resulting in more significant practical effects.
[0004] Although the device has many beneficial effects, it still has the following problems: when the staff operates the drone, the liquid in the water tank gradually decreases as it is sprayed. Once the flight attitude changes, the liquid in the water tank is very easy to shake, which increases the difficulty of the staff operating the drone. In view of this, we propose a forestry pest and disease control spraying device. Utility Model Content
[0005] This application provides a forestry pest and disease control spraying device that solves the technical problem in the prior art where, when operators fly drones, the liquid in the storage tank gradually decreases as the drone is sprayed, and any change in flight attitude easily causes significant shaking of the liquid in the storage tank, thus increasing the difficulty of operating the drone. The device utilizes a sliding plate and baffle to separate the space above the remaining liquid in the storage tank, greatly reducing the amplitude of liquid shaking, effectively avoiding interference with the drone's flight stability caused by liquid shaking, reducing the difficulty of operating the drone, and improving the stability of the drone during operation.
[0006] This application provides a forestry pest and disease control spraying device, including: a drone body;
[0007] The bottom of the drone body is fixedly connected to a support frame, the inside of the support frame is fixedly connected to a storage box, both sides of the top of the storage box are fixedly connected to liquid inlet pipes, the bottom of the storage box is fixedly connected to a nozzle, and one end of the nozzle is equipped with a solenoid valve.
[0008] The storage tank is equipped with an adjustment mechanism inside to prevent excessive liquid sloshing.
[0009] The adjustment mechanism includes a sliding plate, a guide rod is fixedly connected to the inner side of the storage box, the sliding plate is slidably sleeved on the outer side of the guide rod, a slot is opened through the top of the storage box, an electric push rod is rotatably connected in the slot, an installation groove is opened through the center of the top of the sliding plate, the output shaft of the electric push rod is rotatably connected in the installation groove, a baffle is fixedly connected to the bottom end of the output shaft of the electric push rod, a first through groove is opened through both sides of the top of the sliding plate, a second through groove is opened through both sides of the top of the baffle, and the second through groove is offset from the first through groove.
[0010] By adopting the above technical solution and setting an adjustment mechanism, it is easy for staff to position the slide plate and baffle above the liquid surface. The slide plate and baffle separate the space above the remaining liquid in the storage tank, which greatly reduces the amplitude of liquid sloshing. This effectively avoids interference with the flight stability of the drone caused by liquid sloshing, reduces the difficulty of operating the drone, and improves the stability of the drone during operation.
[0011] Optionally, a first sealed bearing is installed in the slot, and the electric push rod is rotatably connected to the slot through the first sealed bearing.
[0012] By adopting the above technical solution, during the operation of the electric actuator, it needs to rotate within the slot to drive the slide plate and baffle to move. The first sealed bearing can reduce the friction between the electric actuator and the slot, ensuring the smooth rotation of the electric actuator. This achieves improved rotation efficiency of the electric actuator, reduced energy loss, and prevents leakage of the medicine through the slot, as well as preventing external dust or foreign objects from entering the storage tank through the slot.
[0013] Optionally, a second sealed bearing is installed inside the mounting groove, and the output shaft of the electric push rod is rotatably connected to the mounting groove through the second sealed bearing.
[0014] By adopting the above technical solution, when the output shaft of the electric actuator drives the baffle to rotate, the second sealed bearing can reduce the friction between the output shaft of the electric actuator and the mounting groove, making the rotation of the output shaft of the electric actuator more flexible. This ensures that the baffle can rotate smoothly, improves the accuracy and flexibility of the adjustment mechanism, and prevents the liquid medicine from flowing onto the slide plate through the mounting groove.
[0015] Optionally, an installation ring is fixedly sleeved on the outer side of the drive shaft of the electric push rod. Two slots are opened on the outer wall of the installation ring. A fixing plate is fixedly connected to the top of the storage box. A slide rod is slidably connected through one side of the fixing plate. A locking plate for cooperating with the slots is fixedly connected to one end of the slide rod.
[0016] By adopting the above technical solution, after the electric push rod rotates to the appropriate position, the operator can insert the card plate into the card slot to lock the mounting ring and the electric push rod, which facilitates the fixation of the electric push rod and prevents the electric push rod from rotating arbitrarily.
[0017] Optionally, a spring is fixedly connected to the side of the card plate near the slide rod, one end of the spring is fixedly connected to the fixed plate, and a pull plate is fixedly connected to the other end of the slide rod.
[0018] By adopting the above technical solution and setting a spring, when the worker pulls the slide bar to move the card plate, the spring will be squeezed, causing the spring to deform, thereby increasing the resistance when the card plate moves, and thus effectively preventing the card plate from falling out of the card slot at will.
[0019] Optionally, a connecting groove is provided at the bottom of the baffle, and a liquid level sensor is installed in the connecting groove.
[0020] By adopting the above technical solution, the liquid level sensor can monitor the liquid level in the storage tank in real time during the spraying operation, which makes it convenient for the staff to take corresponding actions according to the liquid level in the storage tank, such as activating the electric push rod to adjust the position of the slide plate and the baffle, so as to ensure the smooth progress of the spraying operation.
[0021] Optionally, a sealing cap is threaded onto the outside of the inlet pipe, and a handle is fixedly connected to the top of the sealing cap.
[0022] By adopting the above technical solution, when it is not necessary to transport the medicine through the inlet pipe, the staff can tighten the sealing cap on the inlet pipe by the handle to prevent dust, debris and other objects from entering the inlet pipe and contaminating the medicine; when it is necessary to replenish the medicine, the sealing cap can be unscrewed.
[0023] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0024] 1. By setting up an adjustment mechanism, the amplitude of liquid sloshing is greatly reduced, effectively avoiding interference with the flight stability of the drone caused by liquid sloshing, reducing the difficulty for staff to operate the drone, and improving the stability of the drone during operation.
[0025] 2. By setting up an installation ring, a slot, a fixing plate, a sliding rod, and a locking plate, when the electric push rod rotates to the appropriate position, the operator can insert the locking plate into the slot to lock the installation ring and the electric push rod, which facilitates the fixation of the electric push rod and prevents the electric push rod from rotating arbitrarily.
[0026] 3. By setting a spring, when the operator pulls the slide bar to move the pallet, the spring will be compressed, causing the spring to deform and increasing the resistance when the pallet moves, thus effectively preventing the pallet from falling out of the slot at will.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] Reference Figure 1 and Figure 2This application discloses a forestry pest and disease control spraying device. The forestry pest and disease control spraying device includes: a drone body 1;
[0035] A support frame 2 is fixedly connected to the bottom of the drone body 1. A storage box 4 is fixedly connected to the inside of the support frame 2. Liquid inlet pipes 6 are fixedly connected through both sides of the top of the storage box 4. A nozzle 5 is fixedly connected through the bottom of the storage box 4. A solenoid valve is installed at one end of the nozzle 5.
[0036] The storage tank 4 is equipped with an adjustment mechanism 3 inside to prevent excessive liquid sloshing.
[0037] The adjustment mechanism 3 includes a sliding plate 32. A guide rod 31 is fixedly connected to the inside of the storage tank 4. The sliding plate 32 is slidably sleeved on the outside of the guide rod 31. A slot is opened through the top of the storage tank 4. An electric push rod 33 is rotatably connected in the slot. The electric push rod 33 is existing technology and will not be described in detail here. An installation groove is opened through the center of the top of the sliding plate 32. The output shaft of the electric push rod 33 is rotatably connected in the installation groove. A baffle 34 is fixedly connected to the bottom end of the output shaft of the electric push rod 33. A first through groove is opened through both sides of the top of the sliding plate 32. A second through groove is opened through both sides of the top of the baffle 34. The second through groove is offset from the first through groove, so as to prevent the liquid in the storage tank 4 from shaking too much and increasing the difficulty for the operator to operate the drone body 1.
[0038] Reference Figure 1 and Figure 3 A first sealed bearing 35 is installed in the slot, and the electric push rod 33 is rotatably connected to the slot through the first sealed bearing 35, thereby facilitating the prevention of liquid leakage through the slot.
[0039] Reference Figure 3 and Figure 4 The bottom of the slide plate 32 has a groove for accommodating the baffle 34, and the baffle 34 is located in the groove, so that the baffle 34 fits fully with the slide plate 32.
[0040] Reference Figure 3 and Figure 4 A second sealed bearing 36 is installed inside the mounting groove. The output shaft of the electric push rod 33 is rotatably connected to the mounting groove through the second sealed bearing 36, thereby preventing liquid from flowing through the mounting groove to the top of the slide plate 32.
[0041] Reference Figure 2 and Figure 4 The angle between the adjacent first and second channels is 90 degrees, so that after the baffle 34 is rotated 90 degrees, the first and second channels can be aligned, which makes it easier for the staff to transport the medicine through the inlet pipe 6, the first channel and the second channel to the inside of the storage tank 4.
[0042] Reference Figure 2 and Figure 5 An installation ring 37 is fixedly sleeved on the outer side of the drive shaft of the electric push rod 33. Two slots are opened on the outer wall of the installation ring 37. A fixing plate 38 is fixedly connected to the top of the storage box 4. A slide rod 39 is slidably connected through one side of the fixing plate 38. A locking plate 310 for cooperating with the slots is fixedly connected to one end of the slide rod 39, so as to lock the electric push rod 33 and prevent the electric push rod 33 from rotating at will.
[0043] Reference Figure 2 and Figure 4 The angle between the two slots is 90 degrees, which makes it easy for the operator to lock the mounting ring 37 and the electric push rod 33 after rotating the electric push rod 33 and the mounting ring 37 90 degrees.
[0044] Reference Figure 2 and Figure 5 A spring 311 is fixedly connected to the side of the card plate 310 near the slide bar 39. One end of the spring 311 is fixedly connected to the fixed plate 38, and the other end of the slide bar 39 is fixedly connected to the pull plate 7, so as to prevent the card plate 310 from falling out of the card slot at will.
[0045] Reference Figure 3 and Figure 4 The bottom of the baffle 34 is provided with a connecting groove, and a liquid level sensor 9 is installed in the connecting groove. The liquid level sensor 9 is existing technology and will not be described in detail here, so as to facilitate the staff to determine the liquid level in the storage tank 4.
[0046] Reference Figure 1 and Figure 2 The outer side of the inlet pipe 6 is threaded with a sealing cap 8, and the top of the sealing cap 8 is fixedly connected with a handle to prevent foreign objects from entering the inside of the storage box 4.
[0047] The implementation principle of the forestry pest and disease control spraying device in this application embodiment is as follows: When working, the staff operates the drone body 1 to fly. The storage box 4, which is fixedly connected to the support frame 2 at the bottom of the drone body 1, is used to store the pesticide solution. The pesticide solution is sprayed out through the spray pipe 5, which is fixedly connected through the bottom of the storage box 4. The solenoid valve installed at one end of the spray pipe 5 can control the spraying of the pesticide solution.
[0048] During the spraying operation, as the pesticide is sprayed, the amount of pesticide in storage tank 4 gradually decreases. At this time, the operator activates the electric push rod 33, and the output shaft of the electric push rod 33 drives the slide plate 32 and the baffle 34 to move downwards along the guide rod 31. Because the first through-slot is opened through both sides of the top of the slide plate 32, and the second through-slot is opened through both sides of the top of the baffle 34, and the first through-slot and the second through-slot are staggered during spraying, this staggered setting can effectively prevent the pesticide from flowing through the first through-slot and the second through-slot to the top of the slide plate 32 when the slide plate 32 and the baffle 34 move. As the amount of pesticide in storage tank 4 continues to decrease, the slide plate 32 and the baffle 34 eventually reach a suitable position above the liquid surface. In this state, due to the separation effect of the slide plate 32 and the baffle 34 on the space above the remaining pesticide in storage tank 4, when the drone's flight attitude changes, the swaying amplitude of the liquid in storage tank 4 is minimized, thereby effectively suppressing the violent swaying of the pesticide in storage tank 4.
[0049] When the spraying operation is completed and it is necessary to replenish the pesticide solution in the storage tank 4, the operator pulls the pull plate 7 to move the slide rod 39. The movement of the slide rod 39 moves the clamping plate 310 and compresses the spring 311, thereby moving the clamping plate 310 out of one of the slots. Then, the operator can rotate the electric push rod 33 to rotate the baffle 34 90 degrees until the first through slot is aligned with the second through slot. Then, the operator releases the pull plate 7, causing the compressed spring 311 to rebound and move the clamping plate 310 into the other slot, locking the mounting ring 37 and the electric push rod 33 to prevent the electric push rod 33 from rotating arbitrarily. Finally, the operator delivers the pesticide solution into the storage tank 4 through the liquid inlet pipe 6, allowing the pesticide solution to smoothly pass through the first and second through slots into the inside of the storage tank 4.
[0050] This application provides a forestry pest and disease control spraying device. By setting the adjustment mechanism 3, the amplitude of liquid sloshing is greatly reduced, effectively avoiding interference with the flight stability of the drone caused by liquid sloshing, reducing the difficulty of operating the drone for staff, and improving the stability of the drone during operation.

The main controller can be a conventional known device such as a computer. Those skilled in the art can connect all electrical components in this case to their compatible power supplies via wires. Appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described above, where the electrical components are connected in sequence.
