[0002] The pesticide spraying device for agricultural pest control is a key tool for precise and efficient pesticide and biological agent spraying, aiming to control pests and promote crop growth. Modern pesticide spraying devices are developing towards intelligence, precision and low pollution to reduce pesticide abuse and improve control efficiency.

[0003] The patent with publication number CN216874696U discloses a pesticide spraying device for agricultural pest control, which includes a bottom plate, two groups of universal wheels are fixedly connected to the bottom surface of the bottom plate, a water tank is fixedly connected to the upper surface of the bottom plate, a through opening is formed in the upper surface of the water tank, a water pump is fixedly connected to the inner side wall of the water tank, a connecting box is fixedly connected to the left side of the water tank, the patent can extract pesticide solution through the water pump and inject it into the connecting box, the T-shaped sliding plate and T-shaped clamping plate can control the movement of two second shunt boxes, so that the two second shunt boxes can be moved away, increasing the coverage of pesticide spraying, and by opening the electromagnetic valve, the pesticide solution can enter the second shunt box, so that the first and second shunt boxes can spray pesticides at the same time, solving the problem of limited spraying range, which requires workers to walk in the field multiple times when spraying pesticides, reducing work efficiency.

[0004] However, the device cannot overcome the problem of rapid settling of droplets due to gravity in traditional spraying, which makes it difficult to cover the entire area, so a pesticide spraying device for agricultural pest control is proposed to solve the above problems. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a pesticide spraying device for agricultural pest control to overcome the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a spraying device for agricultural pest and disease control, comprising a frame, a medicine tank fixedly connected to the top of the frame, a handlebar mounted at the front of the frame, a seat mounted on the top of the medicine tank, a power assembly fixedly connected to the top of the frame for driving the device, a spraying mechanism provided at the top of the frame, a scraping mechanism mounted on the surface of the spraying mechanism, and a root and stem spraying mechanism provided at the rear of the frame. The spraying mechanism includes: a bearing seat, a mounting frame, a fan, a nozzle, a turntable, and a bracket. The bearing seat is fixedly connected to the top of the frame, the mounting frame is rotatably connected to the inner wall of the bearing seat, and the bracket is fixedly connected to the inner wall of the mounting frame. The fan is fixedly connected to the surface of the bracket, the turntable is rotatably connected to the inner wall of the bracket, the nozzle is fixedly connected to the surface of the turntable, and the nozzle is connected to the bottom of the medicine tank through a pipeline. The turntable is driven to rotate by a motor inside the bracket. The fan is located inside the mounting frame. The medicine tank is equipped with a water pump to pump the liquid medicine to each nozzle. It can blow out a large amount of airflow to drive the droplets to penetrate the crop canopy, overcoming the problem of droplets settling too quickly due to gravity and being difficult to cover the entire crop in traditional spraying. At the same time, the airflow can also turn the leaves, so that the liquid medicine can adhere to the back of the crop leaves that are difficult to reach by traditional spraying. The centrifugal force generated by the rotation of the nozzle will better diffuse the sprayed liquid medicine onto the fan air delivery surface, further improving the coverage of the liquid medicine.

[0007] Preferably, the scraping mechanism includes: a protective net, a connecting seat, a screw, and an adjusting rod. The protective net is fixedly connected to the inner wall of the mounting frame, the connecting seat is fixedly connected to the top of the mounting frame, the screw is rotatably connected to the inner wall of the connecting seat, and the adjusting rod is threadedly connected to the threaded part of the screw, thereby connecting the two screws. The scraping mechanism also includes: a mounting block, a short scraper, and a long scraper. The mounting block is fixedly connected to the four corners of the inner wall of the mounting frame, the short scraper is fixedly connected to the circumferential surface of the turntable, and the long scraper is rotatably connected to the inner wall of the mounting block via a torsion spring. The screws are symmetrically arranged, with one screw having a left-hand thread and the other a right-hand thread. The long scraper is located on the movement trajectory of the short scraper. One side of the adjusting rod has a right-hand internal thread, and the other side has a left-hand internal thread, which can adapt to crops of different heights, improve the flexibility of the device, and reduce the rate of missed spraying of crops. The cooperation between the long scraper and the short scraper can improve the cleaning range and cleaning effect on the surface of the protective net, greatly ensuring the stability of the device during operation.

[0008] Preferably, the root and stem spraying mechanism includes: a connecting column, a second connecting seat, and a rotating arm. The connecting column is fixedly connected to the rear of the vehicle frame, the second connecting seat is fixedly connected to both sides of the connecting column, and the rotating arm is rotatably connected to the inner wall of the second connecting seat. The root and stem spraying mechanism also includes: a fixing ring, a steel wire rope, and a rope winding rod. The fixing ring is fixedly connected to the rear of the vehicle frame, the rope winding rod is fixedly connected to the inner wall of the long scraper, the steel wire rope passes through the fixing ring and is wound around the circumference of the rope winding rod, and a spray head is fixedly connected to the side of the rotating arm away from the second connecting seat. The nozzle fixed at one end of the rotating arm is connected to the medicine tank through a pipe on the inner wall of the rotating arm. The end of the steel wire rope away from the rope winding rod is fixedly connected to the surface of the rotating arm. There is a certain rotational damping between the rotating arm and the connecting seat 2 to maintain the effect of slow rotation of the rotating arm, which can prevent underground pests from harming crops. By applying pesticides at the root and stem, the amount of pesticides can be reduced, and the problem of underground pests that traditional spraying cannot reach can be solved. By tightening and loosening the steel wire rope, the rotating arm can swing slightly, further improving the spraying range and the coverage area of ​​the pesticide mist.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This agricultural pest and disease control spraying device, through the coordinated operation of the bearing seat, mounting frame, fan, nozzle, turntable, and support, can blow out a large amount of airflow to drive the droplets to penetrate the crop canopy, overcoming the problem of droplets settling too quickly due to gravity and failing to cover the entire crop in traditional spraying. At the same time, the airflow can also turn the leaves, allowing the pesticide to adhere to the back of the crop leaves that are difficult to reach with traditional spraying. The centrifugal force generated by the rotation of the nozzle will better diffuse the sprayed pesticide mist onto the fan's air delivery surface, further improving the pesticide mist coverage.

[0010] 2. This agricultural pest and disease control spraying device, through the coordinated operation of the protective net, connecting seat 1, screw, adjusting rod, mounting block, short scraper, and long scraper, can adapt to crops of different heights, improve the flexibility of the device, reduce the rate of missed spraying of crops, and the cooperation between the long scraper and the short scraper can improve the cleaning range and cleaning effect on the surface of the protective net, greatly ensuring the stability of the device during operation.

[0011] 3. This agricultural pest and disease control spraying device, through the cooperation of the connecting column, connecting seat 2, rotating arm, fixing ring, steel wire rope, and rope rod, can prevent underground pests from harming crops. By applying pesticides precisely to the root and stem, it can reduce the amount of pesticides used and solve the problem of underground pests that traditional spraying cannot reach. By tightening and loosening the steel wire rope, the rotating arm can swing slightly, further increasing the spraying range and the coverage area of ​​the pesticide mist. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-9One embodiment of the present invention is: a spraying device for agricultural pest and disease control, comprising a frame 1, a medicine tank 2 fixedly connected to the top of the frame 1, a handlebar 3 mounted on the front of the frame 1, a seat 4 mounted on the top of the medicine tank 2, a power assembly 5 fixedly connected to the top of the frame 1 for driving the device, a spraying mechanism 6 provided on the top of the frame 1, a scraping mechanism 7 mounted on the surface of the spraying mechanism 6, and a root and stem spraying mechanism 8 provided at the rear of the frame 1. The spraying mechanism 6 includes: a bearing seat 601, a mounting frame 602, a fan 603, a nozzle 604, a turntable 605, and a bracket 606. The bearing seat 601 is fixedly connected to the top of the frame 1, the mounting frame 602 is rotatably connected to the inner wall of the bearing seat 601, the bracket 606 is fixedly connected to the inner wall of the mounting frame 602, and the fan 603 is fixedly connected to the inner wall of the mounting frame 602. On the surface of the bracket 606, a turntable 605 is rotatably connected to the inner wall of the bracket 606. A nozzle 604 is fixedly connected to the surface of the turntable 605 and is connected to the bottom of the medicine tank 2 through a pipeline. The turntable 605 is driven to rotate by a motor inside the bracket 606. A fan 603 is located inside the mounting frame 602. A water pump is installed inside the medicine tank 2 to pump the liquid medicine to each nozzle 604. Through the above components, a large amount of airflow can be blown out to drive the droplets to penetrate the crop canopy, overcoming the problem of droplets settling too quickly due to gravity and being difficult to cover the entire crop in traditional spraying. At the same time, the airflow can also turn the leaves, so that the liquid medicine can adhere to the back of the crop leaves that are difficult to reach by traditional spraying. The centrifugal force generated by the rotation of the nozzle 604 can better diffuse the sprayed liquid medicine to the air delivery surface of the fan 603, further improving the coverage of the liquid medicine.

[0016] Working principle: After the operator fills the medicine tank 2, the driving device enters the spraying area. The water pump inside the medicine tank 2 starts, pumping the liquid medicine to the nozzle 604 to form a mist, which is then sprayed out. At the same time, the fan 603 starts, blowing out a large amount of airflow, which drives the droplets to penetrate the crop canopy. This overcomes the problem of droplets settling too quickly due to gravity and making it difficult to cover the entire crop in traditional spraying. The airflow can also turn the leaves, allowing the liquid medicine to adhere to the back of the crop leaves that are difficult to reach with traditional spraying. As the fan 603 rotates, the turntable 605 is driven by the motor inside the bracket 606 to start rotating in a regular alternating forward and reverse direction. The rotation of the turntable 605 drives the nozzle 604 to rotate. The centrifugal force generated by the rotation of the nozzle 604 better diffuses the sprayed mist onto the air delivery surface of the fan 603, further improving the coverage of the mist.

[0017] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the scraping mechanism 7 includes: a protective net 701, a connecting seat 702, a screw 703, and an adjusting rod 704. The protective net 701 is fixedly connected to the inner wall of the mounting frame 602, the connecting seat 702 is fixedly connected to the top of the mounting frame 602, the screw 703 is rotatably connected to the inner wall of the connecting seat 702, and the adjusting rod 704 is threadedly connected to the threaded part of the screw 703, thereby connecting the two screws 703. The scraping mechanism 7 also includes: a mounting block 705, a short scraper 706, and a long scraper 707. The mounting block 705 is fixedly connected to the four corners of the inner wall of the mounting frame 602. At this location, the short scraper 706 is fixedly connected to the circumferential surface of the turntable 605, and the long scraper 707 is rotatably connected to the inner wall of the mounting block 705 via a torsion spring. The screws 703 are symmetrically arranged, with one screw 703 having a left-hand thread and the other a right-hand thread. The long scraper 707 is located on the movement trajectory of the short scraper 706. One side of the adjusting rod 704 has a right-hand internal thread, and the other side has a left-hand internal thread, which can adapt to crops of different heights, improve the flexibility of the device, and reduce the rate of missed spraying of crops. The cooperation between the long scraper 707 and the short scraper 706 can improve the cleaning range and cleaning effect on the surface of the protective net 701, and greatly ensure the stability of the device during operation.

[0018] The root and stem spraying mechanism 8 includes: a connecting column 801, a second connecting seat 802, and a rotating arm 803. The connecting column 801 is fixedly connected to the rear of the frame 1, the second connecting seat 802 is fixedly connected to both sides of the connecting column 801, and the rotating arm 803 is rotatably connected to the inner wall of the second connecting seat 802. The root and stem spraying mechanism 8 also includes: a fixing ring 804, a steel wire rope 805, and a rope winding rod 806. The fixing ring 804 is fixedly connected to the rear of the frame 1, the rope winding rod 806 is fixedly connected to the inner wall of the long scraper 707, the steel wire rope 805 passes through the fixing ring 804 and is wound around the circumference of the rope winding rod 806, and the rotating arm 803 is fixedly connected to the side away from the second connecting seat 802. The nozzle 604 is fixed at one end of the rotating arm 803 and connected to the medicine tank 2 through the pipe on the inner wall of the rotating arm 803. The end of the steel wire rope 805 away from the rope winding rod 806 is fixedly connected to the surface of the rotating arm 803. There is a certain rotational damping between the rotating arm 803 and the connecting seat 2 802 to maintain the effect of slow rotation of the rotating arm 803, which can prevent underground pests from harming crops. By applying pesticides to the root and stem, the amount of pesticides can be reduced, and the problem of underground pests that traditional spraying cannot reach can be solved. By tightening and loosening the steel wire rope 805, the rotating arm 803 is driven to swing slightly, further improving the spraying range and the coverage area of ​​the pesticide mist.

[0019] Working principle: When spraying crops at different heights, rotating the adjusting rod 704 causes the right-hand internal thread of the adjusting rod 704 to drive the right-hand screw 703 into the adjusting rod 704. Simultaneously, the left-hand internal thread of the connecting ring drives the left-hand screw 703 into the adjusting rod 704, shortening the total length of the screw 703. This adjusts the pitch angle of the two mounting frames 602 to accommodate crops at different heights, improving the flexibility of the device and reducing crop underspray. During spraying, the protective net 701 prevents excessively long netting from causing damage. The crop is stirred into the fan 603, which damages the fan. As the device moves, some blades may break off and adhere to the surface of the protective net 701. During the rotation of the turntable 605, the short scraper 706 will also rotate, scraping off the blades attached to the protective net 701. During the rotation of the short scraper 706, it will come into contact with the long scraper 707 and push the long scraper 707 to move. The coordinated operation between the long scraper 707 and the short scraper 706 improves the cleaning range and cleaning effect on the surface of the protective net 701, greatly ensuring the stability of the device during operation.

[0020] For certain crops, the root and stem parts also need to be sprayed with insecticide. In this case, the rotating arm 803 is lowered and the nozzle 604 is aimed at the crop stem to spray, so as to prevent underground pests from harming the crops. By applying pesticides to the root and stem parts, the amount of pesticides can be reduced, and the problem of underground pests that traditional spraying cannot reach can be solved. When the short scraper 706 rotates, it drives the long scraper 707 to rotate. At the same time, the long scraper 707 drives the rope winding rod 806 to rotate. The rotation of the rope winding rod 806 causes the steel wire rope 805 to be wound around the circumference of the rope winding rod 806. As the steel wire rope 805 tightens and loosens, it will cause the rotating arm 803 to swing slightly, further increasing the spray range and the coverage area of ​​the pesticide mist.
