[0022] A sealing cover 103 is provided on the top of the storage barrel 101 through a hinge 104 to effectively prevent seeds from falling due to bumps when the device is moved. At the same time, the threaded nail 105 can effectively seal the storage barrel 101.

[0023] like Figure 4 , Figure 5 As shown, the transmission component 2 includes a rotating shaft 202, the outer surface of which is provided with a spiral blade 203, the left and right ends of the rotating shaft 202 are rotatably connected to the left and right opposite inner walls of the support plate 102, the outside of the rotating shaft 202 is provided with a sowing cylinder 201 fixedly connected to the bottom of the discharge pipe 111, the left and right ends of the sowing cylinder 201 are rotatably connected to the rotating shaft 202, the front side wall of the sowing cylinder 201 is provided with a sowing frame 204, and the front side wall of the sowing frame 204 is provided with a plurality of evenly distributed discharge ports 205.

[0024] Through the transmission component 2, when the rice seeds to be sown need to be discharged, first, the solenoid valve 106 is opened, and the seeds will enter the discharge pipe 111 from the storage barrel 101, and then enter the sowing barrel 201 from the discharge pipe 111. The push plate 107 arranged on the front side of the speed change outer cover 312 is pushed by a person to drive the walking wheel 109 to rotate, and the walking wheel 109 will rotate with the rotating shaft 110 fixedly connected thereto. When the discharge pipe 111 rotates, it cooperates with the speed change component 3 to realize the rotation of the rotating shaft 202 fixedly connected to the sliding rod 303. When the rotating shaft 202 rotates, the spiral blade 203 arranged on the surface of the rotating shaft 202 will rotate accordingly, so that it can evenly disperse the seeds from the discharge pipe 111 into the sowing barrel 201, and then sow the seeds through the discharge port 205 and the sowing frame 204 arranged on the sowing barrel 201 to achieve uniform sowing.

[0025] like Figure 5 , Figure 6 , Figure 7 As shown, the speed change assembly 3 includes two sliding rods 303, two speed change covers 312 and two conveyor belts 313. The tops of the two speed change covers 312 are respectively fixedly connected to the bottoms of the left and right sides of the support plate 102, and the sides of the two speed change covers 312 that are close to each other are fixedly connected to the seeding tube 201. The ends of the two sliding rods 303 that are away from each other are fixedly connected to the inner wall of the speed change cover 312. The outer walls of the two sliding rods 303 are slidably connected with movable sleeves 309. The left and right side walls of the two movable sleeves 309 are rotatably connected with connecting plates 308. The rear ends of the two connecting plates 308 are fixedly connected with threaded caps 307. The inner walls of the two threaded caps 307 are threadedly connected with threaded rods 301. The ends of the two threaded rods 301 that are away from each other penetrate into the outer wall of the speed change cover 312 and are fixed. An adjusting block 302 is connected, and the ends of the two threaded rods 301 that are close to each other are rotatably connected to the inner wall of the speed change outer cover 312. The outer walls of the two movable sleeves 309 are both transmission-connected to the rotating cone 306. The sides of the two rotating cones 306 that are close to each other are each provided with a universal joint 1 305. The ends of the two universal joints 1 305 that are close to each other are rotatably connected to the inner wall of the speed change outer cover 312. The sides of the two rotating cones 306 that are away from each other are each provided with a universal joint 2 310. The ends of the two universal joints 2 310 that are away from each other are each fixedly connected to a turntable 2 311. The outer walls of the two turntables 2 311 are transmission-connected to the turntable 1 304 through a conveyor belt 313. The ends of the two turntables 1 304 that are away from each other are both fixedly connected to a rotating shaft 110 that penetrates the outer wall of the speed change outer cover 312.

[0026] When the speed change assembly 3 is used, the push plate 107 is manually pushed to realize the walking wheel 109 driving the entire device to walk in the field. When the walking wheel 109 rotates, it drives the rotating shaft 110 fixedly connected thereto to rotate. When the rotating shaft 110 rotates, the turntable 1 304 fixedly connected thereto will rotate, and the turntable 2 311 connected thereto through the conveyor belt 313 will rotate. When the turntable 2 311 rotates, the universal joint 2 310 connected thereto will drive the rotating cone 306 to rotate. The other end of the rotating cone 306 is rotatably connected to the inner wall of the speed change outer cover 312, and the outer wall of the rotating cone 306 is transmission-connected with a movable sleeve 309, so that the movable sleeve 309 will rotate with the movable sleeve 309 when it rotates, and the rotating shaft 2 202 fixedly connected thereto will rotate when the movable sleeve 309 rotates, so as to achieve uniform sowing.

[0027] When it is necessary to adjust the sowing frequency or the longitudinal seed sowing distance, the threaded rod 301 fixedly connected to the adjusting block 302 can be driven to rotate by rotating the adjusting block 302. When the threaded rod 301 rotates, the threaded cap 307 threadedly connected thereto will move along the direction of the threaded rod 301. When the threaded cap 307 moves, it moves with the movable sleeve 309 connected thereto through the connecting plate 308. When the movable sleeve 309 moves, the rotation speed of the rotating cone 306 in contact with it will change, thereby completing the change of the sowing frequency and adjusting the longitudinal sowing distance.

[0028] like Figure 5 , Figure 6 , Figure 7 As shown, the rotating cone 306 is a conical structure, the outer walls of the rotating cone 306 and the movable sleeve 309 are provided with wear-resistant materials, the outer wall of the movable sleeve 309 is tightly fitted with the outer wall of the rotating cone 306, and the outer wall of the sliding rod 303 is provided with two raised strips, and the ends of the two sliding rods 303 close to each other penetrate the inner wall of the support plate 102 and are fixedly connected to the rotating shaft 202.

[0029] Since wear-resistant materials are provided on the rotating cone 306 and the movable sleeve 309, they can be effectively transmitted. In addition, the convex strips provided on the slide bar 303 can ensure that the movable sleeve 309 can be effectively rotated without affecting the sliding on the slide bar 303. The distance between the several feed ports 205 is determined according to the space required for the development of rice seedlings.

[0030] The working principle of this rice cultivation sowing device is specifically described below.

[0031] like Figure 1-7 As shown, first, by manually pushing the push plate 107, the walking wheel 109 drives the entire device to walk in the field. When the walking wheel 109 rotates, it drives the rotating shaft 110 fixedly connected thereto to rotate. When the rotating shaft 110 rotates, the turntable 1 304 fixedly connected thereto will rotate, and the turntable 2 311 connected thereto through the conveyor belt 313 will rotate. When the turntable 2 311 rotates, the universal joint 2 310 connected thereto will drive the rotating cone 306 to rotate. The other end of the rotating cone 306 is rotatably connected to the inner wall of the speed change outer cover 312, and the outer wall of the rotating cone 306 is transmission-connected with a movable sleeve 309, so that the movable sleeve 309 will rotate with the movable sleeve 309 when it rotates, and the rotating shaft 2 202 fixedly connected thereto will rotate when the movable sleeve 309 rotates.

[0032] Then open the solenoid valve 106, the seeds will enter the discharge pipe 111 from the storage barrel 101, and then enter the sowing barrel 201 from the discharge pipe 111. The push plate 107 arranged on the front side of the speed change outer cover 312 is pushed by a person to drive the walking wheel 109 to rotate, and the walking wheel 109 will rotate with the rotating shaft 110 fixedly connected thereto. When the discharge pipe 111 rotates, it is used in conjunction with the speed change component 3, and the rotating shaft 202 will rotate, and the spiral blades 203 arranged on the surface of the rotating shaft 202 will rotate accordingly, so that it can evenly disperse the seeds from the discharge pipe 111 into the sowing barrel 201, and then sow the seeds through the discharge port 205 and the sowing frame 204 arranged on the sowing barrel 201, so as to achieve uniform sowing.

[0033] Finally, when it is necessary to adjust the sowing frequency or the longitudinal seed sowing distance, the threaded rod 301 fixedly connected to the adjusting block 302 can be driven to rotate by rotating the adjusting block 302. When the threaded rod 301 rotates, the threaded cap 307 threadedly connected thereto will move along the direction of the threaded rod 301. When the threaded cap 307 moves, it moves with the movable sleeve 309 connected thereto through the connecting plate 308. When the movable sleeve 309 moves, the rotation speed of the rotating cone 306 in contact with it will change, thereby completing the change of the sowing frequency and adjusting the longitudinal sowing distance.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
