[0002] Pest and disease control is an important part of forestry work. The most common method is to control and kill pests by spraying chemical agents.

[0003] Most commercially available seedling spraying devices for forestry pest and disease control are similar in overall structure, consisting of a mobile frame equipped with a water tank, pump, and spray nozzle. The pesticide solution and water are mixed in the water tank and then sprayed out through the pump and nozzle. However, in actual use, there are some functional shortcomings that can be improved. For example, mixing the pesticide directly in the water tank can easily contaminate the tank, making cleaning difficult later. It can also affect the concentration when preparing the pesticide solution later. Different types of pesticides can also react with each other, affecting the control effect. Furthermore, it lacks the function of convenient pesticide addition and pollution prevention.

[0004] Now, a new type of seedling spraying device for forestry pest and disease control is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a seedling spraying device for the control of forest pests and diseases, so as to solve the problem mentioned in the background art that it does not have the function of convenient pesticide application and pollution prevention.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seedling spraying device for forestry pest and disease control, comprising a frame, with four wheels installed at the four corners of the bottom of the frame, a water tank fixedly connected to the middle of the top of the frame, a lithium battery pack fixedly connected to the left side of the top of the frame, a PLC controller fixedly connected to the top of the lithium battery pack, a water pump installed on the right side of the top of the frame, and a spraying assembly for easy spraying and pollution prevention on the right side of the frame.

[0007] The dosing assembly includes a support frame welded and fixed to the right side of the vehicle frame. A medicine tank is fixedly connected to the top of the right side of the support frame, and a dust cover is fitted over the top of the medicine tank. A mixing pipe is fixedly connected to the bottom of the right side of the support frame, and a medicine inlet is fixedly connected to the top of the mixing pipe. A solenoid valve is installed between the medicine tank and the medicine inlet. A rigid pipe is provided on the right side of the mixing pipe, and a flexible hose is movably connected between the mixing pipe and the rigid pipe. A nozzle is fixedly connected to the top of the rigid pipe.

[0008] As a further technical solution of this utility model, the water tank, water pump, and mixing pipe are connected by a pipeline, and the lithium battery pack, PLC controller, water pump, and solenoid valve are electrically connected.

[0009] As a further technical solution of this utility model, the top of the medicine barrel is threaded, and the internal thread of the dust cover matches the external thread of the medicine barrel.

[0010] As a further technical solution of this utility model, the internal parts of the mixing tube, flexible tube, rigid tube, and nozzle are interconnected, and the flexible tubes are arranged at equal intervals.

[0011] As a further technical solution of this utility model, a micro controller is fixedly connected to the right side of the top of the water tank, a speaker is provided on the right side of the micro controller, and a radar liquid level sensor is fixedly connected to the bottom of the micro controller.

[0012] As a further technical solution of this utility model, the radar level sensor penetrates through the top of the water tank and extends into the interior, and the microcontroller, speaker, and radar level sensor are electrically connected.

[0013] As a further technical solution of this utility model, electric cylinders are respectively installed at the front and rear ends of the top of the frame, and a concave wheel frame is fixedly connected to the output end of the electric cylinder. A support wheel is movably connected between the front and rear ends inside the concave wheel frame.

[0014] As a further technical solution of this utility model, the output end of the electric cylinder passes through the frame and extends to the bottom, and the support wheels are symmetrically distributed about the vertical center line of the frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the seedling spraying device for forestry pest and disease control not only realizes the function of convenient pesticide application and pollution prevention, but also realizes the function of convenient water level monitoring, and also realizes the function of convenient elevation over embankments;

[0016] (1) By setting up a support frame, dust cover, medicine tank, solenoid valve, mixing pipe, medicine inlet, hose, hard pipe and nozzle, when in use, clean water is added to the water tank, the water pump draws out the clean water in the water tank and pumps it into the mixing pipe, and then through the hose and hard pipe, it is sprayed out by the nozzle. The operator holds the hard pipe to control the direction of the nozzle. The mixing pipe is based on the Venturi effect. When the water flows through, it will form a negative pressure at the bottom of the medicine inlet, which will draw out the medicine in the medicine tank and mix it into the clean water and spray it out. The solenoid valve controls the amount of medicine. The medicine tank itself is small in size, which is convenient for disassembly and cleaning later, and realizes the function of convenient medicine addition and pollution prevention.

[0017] (2) By setting up a microcontroller, a speaker and a radar level sensor, when the spraying work is carried out, the clean water in the water tank is continuously consumed. The radar level sensor monitors the water level in the water tank in real time. When the water level is lower than the preset threshold, the microcontroller controls the speaker to sound an alarm to remind the staff to replenish the water in time, thus realizing the function of easy water level monitoring.

[0018] (3) By setting up an electric cylinder, a concave wheel frame and a support wheel, when the equipment is being advanced in the forest and encounters a ditch, the electric cylinder is activated. The electric cylinder extends downward and pushes the concave wheel frame and the support wheel to press against the ground, raising the front wheel of the equipment to facilitate crossing the ditch. When crossing a ditch, the equipment can also be raised to make it quickly detach, thus realizing the function of facilitating raising and crossing the ditch. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4A seedling spraying device for the control of forest pests and diseases includes a frame 1, with four driving wheels 15 installed at the four corners of the bottom of the frame 1, a water tank 4 fixedly connected to the middle of the top of the frame 1, a lithium battery pack 2 fixedly connected to the left side of the top of the frame 1, a PLC controller 3 fixedly connected to the top of the lithium battery pack 2, a water pump 5 installed on the right side of the top of the frame 1, and a spraying component for easy spraying and pollution prevention on the right side of the frame 1.

[0026] Please see Figure 1-4 A seedling spraying device for controlling forest pests and diseases also includes a dosing component. The dosing component includes a support frame 6, which is welded and fixed to the right side of the frame 1. A medicine tank 8 is fixedly connected to the top of the right side of the support frame 6. A dust cover 7 is fitted onto the top of the medicine tank 8. A mixing pipe 10 is fixedly connected to the bottom of the right side of the support frame 6. An inlet 11 is fixedly connected to the top of the mixing pipe 10. A solenoid valve 9 is installed between the medicine tank 8 and the inlet 11. A rigid pipe 13 is provided on the right side of the mixing pipe 10. A flexible hose 12 is movably connected between the mixing pipe 10 and the rigid pipe 13. A nozzle 14 is fixedly connected to the top of the rigid pipe 13.

[0027] Water tank 4, water pump 5, and mixing pipe 10 are connected by a pipe. Lithium battery pack 2, PLC controller 3, water pump 5, and solenoid valve 9 are electrically connected. The top of the medicine barrel 8 is threaded. The internal thread of the dust cover 7 matches the external thread of the medicine barrel 8. The mixing pipe 10, hose 12, rigid pipe 13, and nozzle 14 are internally connected. The hose 12 is arranged at equal intervals to facilitate mixing and make subsequent cleaning simple.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the mixing pipe 10 is based on the Venturi effect. When the water flows through it, a negative pressure is formed at the bottom of the inlet 11, which draws out the liquid medicine in the medicine tank 8 and mixes it with the clean water before it is sprayed out. The solenoid valve 9 controls the amount of medicine. The medicine tank 8 itself is small in size, which makes it easy to disassemble and clean later.

[0029] A microcontroller 16 is fixedly connected to the top right side of the water tank 4. A speaker 17 is set on the right side of the microcontroller 16. A radar level sensor 18 is fixedly connected to the bottom of the microcontroller 16. The radar level sensor 18 passes through the top of the water tank 4 and extends into the interior. The microcontroller 16, speaker 17, and radar level sensor 18 are electrically connected to facilitate monitoring of the remaining water volume.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the radar level sensor 18 monitors the water level in the water tank 4 in real time. When the water level is lower than the preset threshold, the microcontroller 16 controls the speaker 17 to sound an alarm to remind the staff to replenish the water in time.

[0031] Electric cylinders 19 are installed at the front and rear ends of the top of the frame 1. The output end of the electric cylinder 19 is fixedly connected to a concave wheel frame 20. The front and rear ends of the concave wheel frame 20 are movably connected to a support wheel 21. The output end of the electric cylinder 19 passes through the frame 1 and extends to the bottom. The support wheel 21 is symmetrically distributed about the vertical center line of the frame 1, which facilitates crossing bumps and ditches.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the electric cylinder 19 extends downward, pushing the concave wheel frame 20 and the support wheel 21 to press against the ground, raising the front wheel of the equipment to facilitate crossing the ridge, and also to quickly detach the equipment when crossing the ditch.

[0033] Working Principle: In use, clean water is first added to the water tank 4. The water pump 5 draws the water from the tank 4 and pumps it into the mixing pipe 10. The water then passes through the flexible hose 12 and rigid pipe 13 before being sprayed from the nozzle 14. The operator holds the rigid pipe 13 to easily control the direction of the nozzle 14. Based on the Venturi effect, the mixing pipe 10 creates a negative pressure at the bottom of the inlet 11 as the water flows through, drawing out the pesticide from the pesticide tank 8 and mixing it with the clean water before spraying. The solenoid valve 9 controls the dosage. The pesticide tank 8 is small in size, facilitating disassembly and cleaning. As the spraying operation progresses, the clean water in the water tank 4 is continuously consumed. The radar level sensor 18 monitors the water level in the tank 4 in real time. When the water level falls below a preset threshold, the microcontroller 16 controls the speaker 17 to sound an alarm, reminding the operator to replenish the water. When the equipment is advancing through the forest and encounters ditches or ridges, the electric cylinder 19 is activated. The electric cylinder 19 extends downward, pushing the concave wheel frame 20 and the support wheel 21 to press against the ground, raising the front wheel of the equipment to facilitate crossing the ridge. When crossing a ditch, the equipment can also be raised to allow it to quickly detach.
