[0003] Then the existing anti-sprinkling mechanism has a limited scope of application, because the height of the existing anti-sprinkling mechanism is generally fixed, and can only be applied to a part of the plants, but not to higher plants.

[0004] For example, the patent specification of an existing Chinese patent (publication number: CN218681482U) discloses a spraying anti-drifting mechanism for an unmanned agricultural plant protection vehicle, including a side frame, a medicine box installed on the upper end of the side frame, a spray rod side rod installed between the upper end of the side frame and the medicine box, and a spray pipe installed at the lower end of the spray rod side rod, wheels in contact with the ground are installed on both sides of the lower end of the side frame, and an anti-drifting mechanism is arranged between the side frame and the spray rod side rod.

[0005] However, in the implementation of relevant technologies, it was found that the spraying and anti-drifting mechanism of the above-mentioned unmanned agricultural vehicle for crop protection had the following problems:

[0006] When the device is in use, it can only prevent pesticides from drifting when the pesticide spraying device is spraying on lower plants. When facing higher plants, because the height of the device is fixed, it can only provide protection within its protection range. Pesticides will still drift everywhere outside its protection range. Generally speaking, the device has a limited scope of application and cannot be applied to plants of different heights.

[0007] In view of this, a spraying and anti-drifting mechanism for a plant protection agricultural unmanned vehicle is provided to overcome the above-mentioned defects. Utility Model Content

[0026] Embodiment 1

[0027] Reference Figure 1-4 The utility model provides a spraying and anti-drifting mechanism for an unmanned agricultural plant protection vehicle: it comprises a side frame 1, a loading plate 2 is installed on the top surface of the side frame 1, a medicine storage box 3 is fixedly installed on the top surface of the loading plate 2, an infusion rod 5 and a nozzle 6 are installed on one side of the medicine storage box 3, a connecting rod 4 is fixedly installed on one side of the loading plate 2, a baffle 7 is fixedly installed on the other side of the connecting rod 4, an air collecting port 12 is fixedly installed at the front end of the baffle 7, a rotatable fan 13 is installed inside the air collecting port 12, an air outlet 19 is opened inside the baffle 7, a mounting frame 10 is fixedly installed at one end of the baffle 7, a motor 11 is fixedly installed on the inner wall of the mounting frame 10, a rotatable second pulley 16 is connected to the front end of the motor 11, a transmission belt 15 is sleeved on the outer wall of the second pulley 16, a first pulley 14 is fixedly connected to the front end of the fan 13, and the transmission belt 15 is sleeved on the outer wall of the second pulley 16 and the outer wall of the first pulley 14 at the same time.

[0028] During the specific implementation, the motor 11 is started first. After the motor 11 is started, it will drive the second pulley 16 to rotate. A transmission belt 15 is sleeved on the outer wall of the second pulley 16, and the other end of the transmission belt 15 is sleeved on the outer wall of the first pulley 14. Therefore, after the second pulley 16 rotates, the first pulley 14 starts to rotate synchronously, and the first pulley 14 is fixedly connected to the front end of the transmission belt 15, so the transmission belt 15 will also be driven to rotate. After the transmission belt 15 rotates, air will be drawn into the interior of the air collecting port 12, and then transmitted to the air outlet 19 by the air collecting port 12, and finally discharged from the bottom end of the air outlet 19. At the end of this stroke, the air will flow out at a higher flow rate to form a wind wall. When the medicine sprayed from the nozzle 6 passes through the wind wall, it will be blown downward by the wind, so that the medicine will not be scattered everywhere.

[0029] By setting the motor 11 to drive the fan 13 to rotate, the air outlet 19 forms a wind wall, so that the medicine cannot be dispersed when passing through the baffle 7 and the bottom of the baffle 7. The device is suitable for both low devices and taller plants, which increases the scope of application of the device and the practicality of the device.

[0030] In addition, when the device needs to spray medicine on taller plants, the power of the motor 11 can be increased to increase the speed of the fan 13, so that the wind flow rate at the air outlet 19 can be faster and the wind wall can be extended farther, thereby more comprehensively preventing the medicine from being sprayed elsewhere.

[0031] Embodiment 2

[0032] Reference Figure 1-4 On the basis of the first embodiment, two mounting blocks are installed on the top surface of the baffle 7, a reciprocating threaded rod 8 is rotatably installed between the two mounting blocks, a moving block 17 is threadedly connected to the outer wall of the reciprocating threaded rod 8, and a scraper 18 is fixedly installed at the bottom end of the moving block 17.

[0033] In addition to the reciprocating threaded rod 8, a guide rod 9 is fixedly installed between the two mounting blocks. The moving block 17 is threadedly connected to the outer wall of the reciprocating threaded rod 8 and can also be movably sleeved on the outer wall of the guide rod 9. Through this arrangement, the moving block 17 can only move in a predetermined direction and will not easily become skewed, thereby increasing the stability of the device operation.

[0034] One side of the threaded rod 8 is fixedly connected to a round rod, and the other end of the round rod is fixedly connected to one side of the second pulley 16. A notch with a height greater than the connecting rod 4 is provided in the middle position of the scraper 18. By providing the notch, the scraper 18 will not be restricted by the connecting rod 4 during movement, and the scraping of the entire baffle 7 can be easily completed.

[0035] A collecting groove is provided at the bottom of the side wall of the baffle 7 close to the loading plate 2. The bottom of the inner wall of the collecting groove is inclined. The inclined collecting groove allows the liquid medicine to be collected by the collecting groove and gathered at one point, making it easier for the user to use it later.

[0036] A rubber sheet is fixedly installed on one side of the scraper 18 close to the side wall of the baffle 7, and the other end of the rubber sheet is tightly fitted with the side wall of the baffle 7. By setting the other end of the rubber sheet to be tightly fitted with the side wall of the baffle 7, the scraper 18 can scrape the side wall of the baffle 7 more cleanly.

[0037] During specific implementation, after the second pulley 16 rotates, it will drive the reciprocating threaded rod 8 to rotate. During the rotation of the reciprocating threaded rod 8, the moving block 17 threadedly connected to the outer wall of the reciprocating threaded rod 8 and the scraper 18 connected to the bottom end of the moving block 17 will be pushed. A rubber sheet is fixedly installed on the side of the scraper 18 close to the inner wall of the baffle 7. Therefore, the scraper 18 will scrape the inner wall of the baffle 7 during the movement, so that the medicine attached to the inner wall of the baffle 7 will be hung down, and a collecting groove is provided at the bottom end of the inner wall of the baffle 7, and the hung medicine will fall into the collecting groove.

[0038] By arranging a reciprocating threaded rod 8 to rotate and drive the moving block 17 and the scraper 18 to move, the medicine attached to the inner wall of the baffle 7 can be scraped off, reducing the corrosion of the baffle 7 by the medicine. At the same time, the collected medicine can be reused, reducing unnecessary loss of medicine and saving resources.

[0039] Working principle:

[0040] When using the utility model, the motor 11 is started first. After the motor 11 is started, the second pulley 16 is driven to rotate. A transmission belt 15 is sleeved on the outer wall of the second pulley 16, and the other end of the transmission belt 15 is sleeved on the outer wall of the first pulley 14. Therefore, after the second pulley 16 rotates, the first pulley 14 rotates synchronously, and the first pulley 14 is fixedly connected to the front end of the transmission belt 15, so the transmission belt 15 is also driven to rotate. After the transmission belt 15 rotates, air will be drawn into the interior of the air collecting port 12, and then transmitted to the air outlet 19 by the air collecting port 12, and finally discharged from the bottom end of the air outlet 19. At the end of this stroke, the air will flow out at a higher flow rate to form a wind wall. When the medicine sprayed from the nozzle 6 passes through the wind wall, it will be blown downward by the wind, so that the medicine will not be scattered everywhere.

[0041] By setting the motor 11 to drive the fan 13 to rotate, the air outlet 19 forms a wind wall, so that the medicine cannot be dispersed when passing through the baffle 7 and the bottom of the baffle 7. The device is suitable for both low devices and taller plants, which increases the scope of application of the device and the practicality of the device.

[0042] In addition, when the device needs to spray medicine on taller plants, the power of the motor 11 can be increased to increase the speed of the fan 13, so that the wind flow rate at the air outlet 19 can be faster and the wind wall can be extended farther, thereby more comprehensively preventing the medicine from being sprayed elsewhere.

[0043] After the second pulley 16 rotates, it will drive the reciprocating threaded rod 8 to rotate. During the rotation of the reciprocating threaded rod 8, the moving block 17 threadedly connected to the outer wall of the reciprocating threaded rod 8 and the scraper 18 connected to the bottom end of the moving block 17 will be pushed. A rubber sheet is fixedly installed on the side of the scraper 18 close to the inner wall of the baffle 7. Therefore, the scraper 18 will scrape the inner wall of the baffle 7 during the movement, so that the medicine attached to the inner wall of the baffle 7 will be hung down, and a collecting groove is provided at the bottom end of the inner wall of the baffle 7, and the hung medicine will fall into the collecting groove.

[0044] By arranging a reciprocating threaded rod 8 to rotate and drive the moving block 17 and the scraper 18 to move, the medicine attached to the inner wall of the baffle 7 can be scraped off, reducing the corrosion of the baffle 7 by the medicine. At the same time, the collected medicine can be reused, reducing unnecessary loss of medicine and saving resources.
