Description
Technical Field
[0001] This utility model relates to the field of rapeseed planting technology, and in particular to a spraying device for pesticides in rapeseed planting. Background Technology
[0002] Rapeseed cultivation refers to agricultural production activities that involve artificially cultivating rapeseed plants to obtain their economic value. As an important oilseed crop and cash crop, pesticide spraying refers to agricultural techniques that involve applying pesticides, fungicides, and other agents to the plants or soil through chemical or biological means during rapeseed cultivation to prevent or control pests and diseases.
[0003] In the rapeseed planting process, pest and disease control is a key link to ensure yield. At present, the commonly used traditional pesticide spraying devices usually have atomizing nozzles fixed on the spray bar. Their spray angle is single and cannot be adjusted. Rapeseed plants are lush, especially in the middle and late stages of growth, when the canopy is closed. The traditional flat spraying method causes the pesticide solution to mainly settle on the upper leaves of the canopy, making it difficult to penetrate to the hidden areas in the middle and lower parts where pests and diseases are more likely to occur, forming dead corners for prevention and control, and affecting the overall spraying effect. Utility Model Content
[0004] The technical problem to be solved by this utility model is that in traditional spraying devices, the atomizing nozzle is usually fixed on the spray bar, and its spray angle is single and cannot be adjusted. Rapeseed plants are lush, especially in the middle and late stages of growth, and the canopy is closed. The traditional flat spraying method causes the liquid to mainly deposit on the upper leaves of the canopy, making it difficult to penetrate to the hidden areas in the middle and lower parts where pests and diseases are more likely to occur.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a rapeseed planting insecticide spraying device, including a pressure plate, a track module for stable walking and moving symmetrically mounted on the bottom of the pressure plate, a water tank for storing insecticide installed on the top of the pressure plate, an electrical control box for controlling the overall start-up of the pressure plate in the center of the pressure plate, spraying adjustment components connected to the water tank on both sides of the pressure plate for spraying the insecticide close to the roots of the rapeseed, and an atomizing spraying component on the pressure plate for turning adjustment to adapt to spraying insecticide in the middle and top of rapeseed of different heights.
[0006] The beneficial effects of this invention are as follows: the spray adjustment components located on both sides of the pressure plate allow for circumferential spraying close to the rapeseed roots, while the atomizing spray components achieve atomized coverage of the upper and middle parts of the plant. The two spraying systems work together to form a three-dimensional application mode from the roots to the top of the canopy, greatly improving the control effect of the pesticide on hidden pests and diseases in the lower and middle parts of the plant and eliminating blind spots in pest control.

[0020] like Figures 2-3 As shown, a conveying pipe 103 is rotatably mounted on the pressure plate 1 away from the center of the spray adjustment component 5. A protective sleeve 102 is fitted on the outside of the conveying pipe 103. A rotating disk 506 inserted into the pressure plate 1 passes through the center of the conveying pipe 103. A first drive motor 104 is located at the center of the rotating disk 506. Several diversion pipes 106 are linearly and vertically connected to the conveying pipe 103. The first drive motor 104 drives the rotating disk 506 to rotate the conveying pipe 103 and the diversion pipes 106 at different angles. A diversion pipe 109 connected to the water tank 3 is located at the outer end of the conveying pipe 103. A control pump 105 is located at both ends of the conveying pipe 103. Several sets of spray holes 108 are linearly opened on the diversion pipes 106. A high-definition camera 107 is located between two sets of spray holes 108.

The tracked chassis provides good ground passability and stability, making it suitable for wet and soft rapeseed field environments and reducing the labor intensity of operators.
[0022] like Figures 4-5As shown, several sets of atomizing tubes 409 are linearly connected to the main tube 408. A fan 410 is connected to the outer end of each atomizing tube 409. An injector is installed inside each atomizing tube 409 (for root spraying, an anti-clogging fan-shaped nozzle (such as the TeeJet series) can be used; for canopy spraying, a centrifugal atomizing disc head or a hollow cone nozzle can be used to achieve the best atomization effect). A rotating rod 406 is provided between the guide arm 405 and the extension arm 403. The outer end of the rotating rod 406 is connected to the first lithium battery pack 407. The first lithium battery pack 407 drives the rotating rod 406 to swing the guide arm 405 and the extension arm 403. A vent 412 is provided at one end of the fan 410.

A rotating shaft 504 is located at the center of the end of the guide arm 501 away from the guide arm 501. A medicine pipe communicating with the water tank 3 is located at the outer end of the rotating shaft 504. A rotating disk 506 is connected to one end of the rotating shaft 504. A rotator is located at the center of the rotating disk 506. A third lithium battery pack 505 is electrically connected to the outer end of the rotator. One end of 06 is connected to a straight cylinder 507. Several sets of dispersing cylinders 508 are circumferentially connected to the outer end of the straight cylinder 507. Sprayers are provided inside the dispersing cylinders 508 and the straight cylinder 507. Flexible dispersing strips 510 are provided between the two sets of dispersing cylinders 508. Anti-corrosion rings 509 are attached to the end of the straight cylinder 507. The third lithium battery pack 505 drives the rotator to drive the rotating disk 506 to rotate, which is used to drive the straight cylinder 507 and the dispersing cylinder 508 to spray circumferentially. The flexible dispersing strips 510 are simultaneously and flexibly dispersed. Integrated water pressure sensor 110 (e.g., MPX5100DP), air pressure sensor 415 (e.g., MS5837-30BA), and hydraulic sensor 303 (e.g., Honeywell MLH series) can monitor the system pressure status in real time, while a high-definition camera 107 (e.g., an industrial endoscope camera) provides field visual feedback. Based on sensor data, the control system can automatically adjust pump pressure, blower 410 wind speed (via motor 411), and spray boom angle (via first and second drive motors 404 and a rotator), enabling the device to adapt to rapeseed fields at different growth stages and densities, significantly improving the effective utilization rate of pesticides. Key components such as the fan 410 are covered with a waterproof sleeve 413 (material: silicone or TPU), and the straight cylinder 507 has an anti-corrosion ring 509 (material: polytetrafluoroethylene PTFE) at its end, improving the durability and corrosion resistance of the device. The flexible dispersion strip 510 (material: pesticide-resistant NBR rubber) gently separates the plants during circumferential spraying, reducing mechanical damage to the crop and assisting in the dispersion of the pesticide solution, further improving the uniformity of spraying.
[0023] Working principle: Before operation, the insecticide is injected into water tank 3 and sealed. The entire system is started via electrical control box 101, and the device moves between the rapeseed rows under the drive of tracked module 2; The spraying adjustment component 5 starts working, and the second lithium battery pack 503 drives the connecting shaft 502 to adjust the guide arm 501 to a suitable height. The third lithium battery pack 505 drives the rotator, which drives the rotating disk 506 and the straight cylinder 507 and the dispersing cylinder 508 fixed thereto to rotate at a uniform speed. The pesticide solution is pumped from the water tank 3 into the straight cylinder 507 through the pesticide solution pipe, and sprayed outward in a ring direction through the injector (such as a fan-shaped atomizing nozzle) on the dispersing cylinder 508. At the same time, the flexible dispersing strip 510 (NBR rubber strip) gently separates the rapeseed leaves at the base during rotation, so that the pesticide solution can penetrate more fully into the base of the stem and the soil surface to control basal pests. The atomizing spraying component 4 works synchronously. The liquid medicine is transported from the water tank 3 to the main pipe 408 through the connecting pipe 305. The first drive motor 104 drives the rotating disk 506, which can adjust the overall tilt angle of the conveying pipe 103 and the diversion pipe 106 to adapt to the height of the rapeseed plants. The nozzle 108 on the diversion pipe 106 (such as a centrifugal atomizing nozzle) atomizes and sprays out the liquid medicine. At the same time, the second drive motor 404 drives the steering rod 402 to adjust the swing angle of the extension arm 403. The first lithium battery pack 407 drives the rotating rod 406 to adjust the pitch angle of the guide arm 405, thereby ultimately and accurately positioning the spatial position of the main tube 408 and the atomizing tube 409 so that they can cover the rapeseed canopy from the side and above. Driven by the control motor 411, the blower 410 generates airflow that is blown out from the air hole 412 and the ventilation slot 414. This airflow has a dual function: first, it further atomizes the droplets sprayed from the atomizing tube 409 and pushes them into the depth of the rapeseed canopy to enhance penetration; second, it forms an air curtain to effectively reduce the drift of fine droplets and improve the deposition rate. Throughout the process, various sensors continuously monitor the spraying process: water pressure sensor 110 monitors the pressure in the diversion pipe 106, air pressure sensor 415 monitors the air pressure in the blower 410, and hydraulic sensor 303 monitors the water level in the water tank 3. The data is fed back to the electrical control box 101, and the control system adjusts the operating parameters of each pump and motor in real time according to a preset algorithm, achieving precise and adaptive variable spraying. A high-definition camera 107 captures the operation footage, which can be used to assist in operation or for later evaluation of the spraying effect.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
