A tobacco brown spot disease prevention and control spraying device according to claim 8, characterized in that: A circular ring (129) is slidably connected to the outer wall of the driving rod (11), the top of the circular ring (129) is fixedly connected to the outer wall of the sleeve (121), the circular ring (129) is hinged to one end of a support rod (1291), and the other end of the support rod (1291) is hinged to the gravity cylinder (127).

10. A method for preventing and controlling tobacco brown spot disease, characterized in that: The control method comprises the following steps: S1. First, the driving rod 11 is driven to rotate by starting the motor 10, and then the stirring rod 122 on the outer wall of the sleeve 121 is driven by the driving rod 11 to rotate to stir the internal medicine solution evenly. During the stirring process, part of the solution flows to the rear of the stirring rod 122 through the through hole 123 provided on the stirring rod 122 to prevent the internal solution from making a circular motion with the stirring rod 122 and causing uneven stirring. S2. At the same time, the scraper 124 on the outer wall is driven by the stirring rod 122 to rotate to clean and scrape the inner wall of the medicine jar 2 to prevent residual medicine on the inner wall. The scraped medicine is then allowed to flow to the middle of the medicine jar 2 through the setting of the inclined groove 125 for easy stirring again. The gravity cylinder 127 outside the fixed rod 126 is then driven by the driving rod 11 to rotate to generate centrifugal force, thereby causing the two gravity cylinders 127 to move backwards. The gravity cylinder 127 pulls the bottom end of the support rod 1291, and then the support rod 1291 is hinged with the ring 129 to drive the upper sleeve 121 to move downward, thereby controlling the rotation of the driving rod 11, so that the sleeve 121 drives the scraper 124 on the outer wall of the stirring rod 122 to move up and down. S3. The medicine inside the medicine tank 2 is then sucked into the water spraying mechanism 7 through the water absorption mechanism 6 to spray the tobacco plants. At the same time, the eccentric wheel 133 on the outer wall is driven by the driving rod 11 to rotate to squeeze the outer wall of the bent rod 132, so that the bent rod 132 drives the fixed frame 134 at the end to move in the direction of the squeezing rod 138, and then the internal squeezing block 137 is driven by the fixed frame 134 to squeeze the outer wall of the squeezing rod 138. The outer wall of the squeezing rod 138 is squeezed, so that the water absorption mechanism 6 drives the water spraying mechanism 7 on the outer wall to rotate around the rotating rod 4, and then the elastic force of the reset torsion spring 5 is used to make the water absorption mechanism 6 drive the water spraying mechanism 7 on the outer wall to rotate and reset, and finally the water spraying mechanism 7 swings left and right. S4. When the spraying range needs to be adjusted, the extrusion block 137 is pushed to the right, so that the extrusion block 137 drives the adjustment plate 144 on the fixed block 141 to move to the right, and then the adjustment plate 144 drives the clamping block 145 on the outer wall to move to the right, and the arc-shaped outer wall of the clamping block 145 is squeezed, so that the clamping block 145 drives the adjustment plate 144 to rotate so that the limit is released, and then the elastic force of the limit torsion spring 143 is used to make the adjustment plate 144 drive the clamping block 145 to rotate and reset and be clamped into the inside of the clamping slot 146, so that the position of the extrusion block 137 is clamped and fixed, and the distance between the extrusion block 137 and the extrusion rod 138 is adjusted, so that the extrusion degree of the extrusion rod 138 by the extrusion block 137 is adjusted.
