DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 8 As shown, an automatic vegetable seeder described in an embodiment of the present invention includes a frame 1, both ends of the frame 1 are rotatably connected to a wheel group 11, a handrail is fixed to one side of the top of the frame 1, and a transmission gear 111 is fixed to the outside of the rotating shaft of the wheel group 11 away from the handrail, a sowing box 2 is provided in the middle part of the frame 1, and a linkage gear 112 is provided on the side of the transmission gear 111 close to the sowing box 2, the transmission gear 111 can be meshed and connected with the linkage gear 112, and the linkage gear 112 is rotatably connected to the frame 1, and a pulley is fixed on the side of the linkage gear 112 close to the frame 1, and a discharging shell 24 is fixed to the bottom end of the sowing box 2, and a feeding wheel 241 is rotatably connected to the inside of the discharging shell 24, and a plurality of storage troughs are provided at equal intervals on the outside of the feeding wheel 241, and a pulley is also fixed to the end of the rotating shaft of the feeding wheel 241, and the pulley of the feeding wheel 241 is connected to the pulley of the linkage gear 112 by a belt, and a discharging pipe 242 is fixed to the bottom end of the discharging shell 24; A pair of feed hoppers 21 are provided at the top of the seeding box 2, and a sieve plate 211 is fixed below the feed hopper 21, and the sieve plate 211 is connected to the rotation of the seeding box 2; Among them, the sieve plate 211 can screen the seeds inside the feed hopper 21; When planting vegetables, it is necessary to sow vegetable seeds into the soil. In order to sow more efficiently, a seeder is used. When using the seeder, the armrest of the frame 1 is pushed, and the frame 1 can be driven to move. The frame 1 rolls on the ground through the wheel group 11, and the frame 1 can be moved to the area where planting is required. Then, the interior of the seeding box 2 is loaded with vegetable seeds, and the vegetable seeds enter the top of the discharge shell 24. After the seeds are loaded, the frame 1 is pushed to move. At this time, the wheel group 11 rolls on the ground, and the wheel group 11 drives the transmission gear 111 to rotate by rotating. The outer side of the transmission gear 111 is provided with teeth with a length of one-sixth of the circumference. Therefore, every time the transmission gear 111 rotates one circle, it drives the linkage gear 1 12 rotates one-sixth of a circle, at which time the linkage gear 112 drives the feeding wheel 241 to rotate through the belt and the pulley. Six storage troughs are provided on the outside of the feeding wheel 241, and the storage troughs match the transmission gear 111, and can switch the position of a storage trough every time the transmission gear 111 rotates one circle. When the storage trough of the feeding wheel 241 rotates to the top position of the discharge shell 24, the vegetable seeds will enter the storage trough, and then as the feeding wheel 241 continues to rotate, the storage trough brings the vegetable seeds into the discharge pipe 242. At this time, the vegetable seeds fall into the discharge pipe 242, and the discharge pipe 242 can output the seeds to the outside. At this time, the sowing of one position can be completed, and automatic sowing can be achieved by this reciprocating motion; The seeds need to be fertilized at the same time as planting. In order to save time for fertilization, the seeds and fertilizers are sown at the same time. When the seeds are placed in the sowing box 2, they are placed in one of the feed hoppers 21 and the fertilizer is placed in the other feed hopper 21. At this time, the sieve plate 211 below the feed hopper 21 can screen the seeds and fertilizers, and can screen out the stones or larger granular fertilizers inside the seeds and fertilizers. At this time, the feeding wheel 241 can be prevented from being stuck by stones or large granular fertilizers. The two sieve plates 211 are set with different apertures for seeds and fertilizers, which can screen out objects larger than the aperture, thereby preventing the feeding wheel 241 from being stuck inside the discharge shell 24.

[0024] like Figures 1 to 9 As shown, a shifting frame 214 is provided at the top of the sieve plate 211, a push block 215 is fixed to one side of the shifting frame 214, and the push block 215 is slidably connected to one side of the feed hopper 21, and a first motor 22 is installed on one side of the seed box 2; When the first motor 22 rotates, it drives the shifting frame 214 to slide back and forth on the top of the sieve plate 211; When the sieve plate 211 is screening the seeds and fertilizers inside the feed hopper 21, the inside of the feed hopper 21 is in a stationary state and the screening efficiency is low. At this time, the first motor 22 is started to rotate and drive the push block 215 to slide inside the feed hopper 21. When the push block 215 slides, it drives the shifting rack 214 to slide on the top of the sieve plate 211. At this time, the shifting rack 214 can drive the vegetable seeds and fertilizers inside the feed hopper 21 to move. At this time, the vegetable seeds and fertilizers can be screened through the mesh of the sieve plate 211 more quickly to prevent accumulation inside the feed hopper 21.

[0025] like Figures 1 to 9 As shown, the middle part of the sowing box 2 is rotatably connected to the mixing frame 221, the end of the rotating shaft of the first motor 22 is fixedly connected to one end of the mixing frame 221, and a guide slide groove 224 is provided on the outer side of the end of the mixing frame 221 away from the first motor 22. The end of the mixing frame 221 away from the first motor 22 is rotatably connected to the movable plate 222. A positioning rod is fixed on the side of the sowing box 2 close to the movable plate 222, the positioning rod passes through the middle of the movable plate 222, and a protrusion 225 is fixed inside the movable plate 222. The protrusion 225 is slidably connected to the inside of the guide slide groove 224. A connecting plate 223 is provided at the top of the movable plate 222, and a second guide rod 226 is fixed to the bottom end of the connecting plate 223. The second guide rod 226 is inserted into the inside of the movable plate 222, and a pulling arm 228 is fixed on both sides of the connecting plate 223. When the mixing rack 221 rotates, the guide slot 224 and the protrusion 225 drive the moving plate 222, and the moving plate 222 drives the shifting rack 214 to move; After the vegetable seeds and fertilizers enter the sowing box 2, in order to make the seeds and fertilizers more evenly mixed during sowing, the first motor 22 rotates to drive the mixing rack 221 to stir and mix the seeds and fertilizers inside the sowing box 2, so that the fertilizers and seeds can be mixed together; When the mixing rack 221 rotates, the guide chute 224 is driven to rotate. When the guide chute 224 rotates, the protrusion 225 is inside the guide chute 224. The inner wall of the guide chute 224 guides the protrusion 225, so that the protrusion 225 can move back and forth at the end of the mixing rack 221. At this time, the protrusion 225 drives the movable plate 222 to move, and the movable plate 222 can keep stable movement through the limitation of the positioning rod. When the movable plate 222 moves, it drives the connecting plate 223 to move through the second guide rod 226, and the connecting plate 223 drives the pulling arm 228 to push the pushing block 215. At this time, the pushing block 215 can drive the shifting rack 214 to slide on the top of the screen plate 211, thereby driving the seeds and fertilizers inside the feed hopper 21 to move, thereby improving the screening efficiency of the screen plate 211.

[0026] like Figures 1 to 9As shown, a guide sleeve 218 is fixed to one side of the feed hopper 21, and a first guide rod 216 is fixed to the side of the push block 215 close to the guide sleeve 218. The first guide rod 216 passes through the interior of the guide sleeve 218, and a spring 217 is sleeved on the outside of the first guide rod 216. One end of the spring 217 is fixedly connected to the push block 215, and the other end of the spring 217 is fixedly connected to the guide sleeve 218. When the pulling arm 228 moves forward, the pushing block 215 is pushed by the pulling arm 228, and the pushing block 215 drives the first guide rod 216 to slide inside the guide sleeve 218. At the same time, the spring 217 is squeezed by the pushing block 215. When the pulling arm 228 moves backward, the pushing block 215 loses the thrust of the pulling arm 228. At this time, the spring 217 pushes the pushing block 215, and the pushing block 215 drives the shifting frame 214 to slide in the opposite direction at the top of the screen plate 211. The reciprocating sliding of the shifting frame 214 drives the seeds and fertilizers inside the feed hopper 21 to move, making it easier to screen.

[0027] like Figures 1 to 8 As shown, a connecting arm 212 is fixed to the end of the rotating shaft of the sieve plate 211 away from the connecting plate 223, and the other end of the connecting arm 212 is rotatably connected to the first pull rod 213. A second motor 23 is installed on the side of the seed box 2 close to the first motor 22 through a connecting block. A screw rod 238 is fixed to the end of the rotating shaft of the second motor 23. The external thread of the screw rod 238 is connected to the lifting frame 231. Second pull rods 233 are fixed to both sides of the top of the lifting frame 231. The top of the second pull rod 233 is rotatably connected to the first pull rod 213. When the lifting frame 231 is lowered to the lowest position, the sieve plate 211 rotates 90° to both sides at the top of the sowing box 2. When the lifting frame 231 is raised to the highest position, the sieve plate 211 rotates 90° at the top of the sowing box 2 toward the center of the sowing box 2. When the seeds and fertilizers inside the feed hopper 21 are screened, it is necessary to clean the objects screened out from the feed hopper 21. At this time, the second motor 23 is started, and the lifting frame 231 in the initial position is at the highest position. The second motor 23 drives the screw rod 238 to rotate to drive the lifting frame 231 to move downward, and the lifting frame 231 drives the two second pull rods 233 to move downward. At this time, the second pull rod 233 pulls the first pull rod 213, and the first pull rod 213 pulls the connecting arm 212 to rotate. When the lifting frame 231 moves to the lowest position, the connecting arm 212 can drive the screen plate 211 to rotate 90°. At this time, the objects screened out from the feed hopper 21 can be dumped to the outside, thereby completing the cleaning of the inside of the feed hopper 21. When the sieve plate 211 and the feed hopper 21 need to be reset, the second motor 23 is started to rotate in the opposite direction. At this time, the lifting frame 231 drives the second pull rod 233 to move upward, and the second pull rod 233 can drive the connecting arm 212 to rotate in the opposite direction by 90° through the first pull rod 213. At this time, the sieve plate 211 and the feed hopper 21 can be reset, so that the objects inside the feed hopper 21 can be cleaned conveniently.

[0028] like Figures 1 to 8 As shown, a baffle 219 is fixed to the bottom end of the rotating shaft of the sieve plate 211. The baffle 219 has the same size as the sieve plate 211, and the angle between the sieve plate 211 and the baffle 219 is 90°. After the feed hopper 21 and the sieve plate 211 are cleaned, they will remain in a clean state. At this time, the baffle 219 will rotate the top of the sowing box 2, which can block the top of the sowing box 2 and prevent objects from entering the interior of the sowing box 2 during the sowing process.

[0029] like Figures 1 to 7 As shown, a first curved plate 234 is provided on both sides of the mixing rack 221. The first curved plate 234 is fixedly connected to the inner wall of the seed box 2. A second curved plate 235 is rotatably connected below the first curved plate 234. The ends of the two second curved plates 235 away from the first curved plate 234 can be tightly attached. When the mixing rack 221 rotates, the ends of the two second curved plates 235 are pressed against each other; When the mixing rack 221 mixes the seeds and fertilizers inside the sowing box 2, a first curved plate 234 and a second curved plate 235 are set inside the sowing box 2 to facilitate mixing. When the mixing rack 221 rotates, the first curved plate 234 and the second curved plate 235 can limit the unmixed seeds and fertilizers to the outside of the mixing rack 221. When the mixing rack 221 completes mixing the seeds and fertilizers, the two second curved plates 235 are opened to input the seeds and fertilizers into the bottom end of the sowing box 2, thereby preventing the discharge pipe 242 from outputting the seeds and fertilizers to the outside when they are not mixed.

[0030] like Figures 1 to 7 As shown, guide frames 232 are fixed to both ends of the lifting frame 231, and a pull frame 236 is provided below the second curved plate 235. One end of the pull frame 236 is slidably connected to the inside of the guide frame 232, and the pull frame 236 runs through both sides of the seed box 2; When the lifting frame 231 rises to the highest point, the pulling frame 236 is at the lowest point inside the guide frame 232. At this time, the pulling frame 236 can drive the second curved plates 235 to close, which makes it easier for the mixing frame 221 to mix materials. When the lifting frame 231 falls to the lowest point, the guide frame 232 guides the pulling frame 236 to extend it to the outside of the sowing box 2. At this time, the pulling frame 236 can pull the second curved plates 235 to separate them, so that the mixed fertilizer and seeds can be output to the lower area inside the sowing box 2, thereby realizing automatic opening and closing of the second curved plates 235.

[0031] like Figure 7 As shown, a connecting frame 237 is fixed to the bottom end of the second curved plate 235, and the other end of the pull frame 236 is slidably connected to the connecting frame 237; When the pull rack 236 moves, the guidance of the seed box 2 will keep it moving on the same horizontal line. In order to prevent interference between the second curved plate 235 and the pull rack 236, a sliding connection is set between the connecting frame 237 and the pull rack 236. The pull rack 236 slides inside the connecting frame 237 to prevent interference between the second curved plate 235 and the pull rack 236.

[0032] like Figure 5 As shown, a push rod 227 is sleeved on the outer portion of the second guide rod 226, the top end of the push rod 227 is fixedly connected to the connecting plate 223, and the bottom end of the push rod 227 is fixedly connected to the movable plate 222; When the feed hopper 21 rotates, it will contact the pulling arm 228 and press the pulling arm 228 downward. At this time, the pulling arm 228 drives the second guide rod 226 through the connecting plate 223 to extend into the interior of the movable plate 222, so that the pulling arm 228 can automatically give way. After the feed hopper 21 is reset, the elastic force of the push rod 227 pushes the connecting plate 223 to drive the pulling arm 228 to reset, so that the pulling arm 228 can be automatically reset.
