Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sowing devices, and in particular to a sowing device used in agricultural drones. Background Art
[0002] At present, drones are widely used in various fields. Drones used in the agricultural field are called agricultural plant protection drones. Because agricultural plant protection drones are small in size, light in weight, can take off and land vertically, and have flexible flight control, they have good adaptability to different regions, different plots, and different crops. Therefore, they have broad application prospects. Agricultural plant protection drones are used to spray pesticides, powders, etc.
[0003] Through searching, Chinese patent publication number CN221585754U discloses a drone green manure sowing device, including a pod and a linkage assembly, wherein the linkage assembly is rotatably installed inside the pod. The present application provides a drone green manure sowing device. Through the setting of the linkage assembly, when in use, the motor transmits rotational transmission to the driven wheel and the rotating rod coaxially therewith through a pulley. Furthermore, the rotating rod synchronously drives the coaxial stirring rod at the top, the coaxial feeding screw in the middle, and the coaxial sowing disc at the bottom to rotate coaxially. Only one motor is needed as the power source to simultaneously achieve the stirring and anti-sticking of the soaked seeds in the grain storage chamber, the anti-blocking of the discharging of the sowing port, and the uniform sowing under the action of centrifugal force when the sowing disc rotates. The discharging speed can be controlled by adjusting the motor speed. By adjusting the angle of the baffle, the speed and angle of the seed flying out can be effectively controlled, thereby controlling the sowing width and area, and effectively improving the sowing quality.
[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: when in use, the above-mentioned scheme only needs one motor as a power source, which can simultaneously realize the stirring and anti-adhesion of the soaked seeds in the grain storage chamber, the anti-blocking of the discharge of the sowing port, and the uniform sowing under the action of centrifugal force when the sowing disc rotates. The discharge speed can be controlled by adjusting the motor speed. By adjusting the angle of the baffle, the speed and angle of the seed flying out can be effectively controlled, and then the sowing width and area can be controlled, and the sowing quality can be effectively improved. However, this device cannot quickly disassemble and assemble the fixed frame with the sowing box. During long-term use, the seeds inside the sowing box will shed some impurities such as the outer skin. These impurities gather and block the sowing box, and the inside of the sowing box needs to be cleaned regularly. Therefore, it is necessary to be able to quickly disassemble and assemble the fixed frame with the sowing box to prevent damage to the drone during the cleaning process. Utility Model Content

The outer surface of the second connecting rod 13 is slidably connected to the two elliptical blocks 18. Each slider 14 can slide vertically along the corresponding sliding groove 15. Through the connection between the second connecting rod 13 and the two sliders 14, the two sliders 14 will move synchronously with the second connecting rod 13. Through the setting of the elliptical block 18, the elliptical block 18 will push the second connecting rod 13 during the rotation process to make it move vertically in a circular motion.
[0024] See also Figure 3 , slots 8 are provided on the left and right sides of the fixing frame 7, and fixed columns 3 are fixedly connected on the left and right sides of the connecting frame 2. The inner wall of each fixing column 3 is slidably connected to an insertion rod 4, and the ends of the two insertion rods 4 away from each other are fixedly connected to a pull block 5. Each insertion rod 4 can slide horizontally along the corresponding fixing column 3, and the size of each slot 8 is the same as the size of the corresponding insertion rod 4.
[0025] See also Figure 4 A sowing box 9 is fixedly installed on the inner wall of the fixed frame 7, and a first connecting rod 10 is fixedly connected to the inner wall of the sowing box 9. The outer surface of the first connecting rod 10 is slidably connected to a conical block 11. The outer surface of the conical block 11 is slidably connected to the sowing box 9. Specifically, the first connecting rod 10 is vertically placed on the inner top wall of the sowing box 9. By placing the conical block 11 on the first connecting rod 10 and then pushing the conical block 11, it can slide along the first connecting rod 10 and the sowing box 9 at the same time, and the outer circle size of the conical block 11 is the same as the discharge port of the sowing box 9, and its inner circle size is the same as the first connecting rod 10.
[0026] See also Figure 3 、 Figure 4The outer surface of each insertion rod 4 is plugged into the corresponding slot 8, and the outer surface of each insertion rod 4 is sleeved with a spring 6. One end of each spring 6 close to the fixing frame 7 is fixedly connected to the corresponding insertion rod 4, and the other end is fixedly connected to the corresponding fixing column 3. By pulling the pull block 5, it can drive the corresponding insertion rod 4 to slide horizontally along the corresponding fixing column 3 until the insertion rod 4 fully enters the corresponding fixing column 3.

[0028] See also Figure 4 A motor 16 is fixedly mounted on the outer surface of the fixing frame 7, and the output end of the motor 16 is fixedly connected to a third connecting rod 17. The outer surface of the third connecting rod 17 is fixedly connected to two elliptical blocks 18. By starting the motor 16, the motor 16 will drive the third connecting rod 17 to rotate in the fixing frame 7. At this time, the rotation of the third connecting rod 17 will drive the two elliptical blocks 18 to rotate. The two elliptical blocks 18 and the third connecting rod 17 are on the same central axis.
[0029] The implementation principle of the sowing device used in an agricultural drone in the embodiment of the present application is as follows: first, the sowing box 9 is installed on the fixing frame 7, and the fixing frame 7 is horizontally inserted along the connecting frame 2. During this process, it is necessary to pull the pull block 5 to make it slide horizontally along the corresponding fixing column 3, and the insertion rod 4 is pulled into the corresponding fixing column 3 by pulling the pull block 5, and then the spring 6 will be compressed until the slot 8 and the corresponding insertion rod 4 are on the same central axis. At this time, the pull block 5 is released, and the spring 6 will push the corresponding insertion rod 4 into the corresponding slot 8 under the action of its rebound force, so as to complete the rapid fixation of the fixing frame 7. The motor 16 is then started, which drives the third connecting rod 17 to rotate in the fixed frame 7. At this time, the rotation of the third connecting rod 17 drives the two elliptical blocks 18 to rotate. The rotation of the elliptical block 18 pushes the second connecting rod 13 to push the slider 14 to slide vertically along the corresponding slide groove 15, and the second connecting rod 13 pushes the conical block 11 through the connecting block 12 to slide vertically along the first connecting rod 10 and the sowing box 9, and the opening and closing of the sowing box 9 by the conical block 11 allows the seeds inside the sowing box 9 to be evenly discharged, and can prevent the seeds from stacking and causing the discharge port to be blocked.
