[0002] Vegetables are a common food in our lives. When growing vegetables, we need to sow vegetable seeds in the soil. To speed up the sowing process, we use automatic seeders. Automatic seeders can sow seeds according to preset spacing and sowing quantity.

[0003] A Chinese patent with publication number CN111587641B discloses a vegetable planter, which includes at least one planting device. Through the cooperation of a seed metering unit, a furrow opener unit, a power transmission unit, and a row spacing adjustment unit, the plant spacing can be adjusted while the row spacing can be adjusted during vegetable planting.

[0004] The above technical solution requires the sowing of vegetable seeds during use. However, some of the sown vegetable seeds are self-saved seeds. Self-saved seeds may contain small stones or other objects. If small stones enter the inside of the seeder, they can easily jam the internal feed wheel, making it impossible to sow normally.

[0005] Therefore, the present invention provides an automatic vegetable planter. Summary of the Invention

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 8 As shown in the embodiment of the present invention, an automatic vegetable planter includes a frame 1, with wheel sets 11 rotatably connected to both ends of the frame 1. A handrail is fixed to one side of the top of the frame 1. A transmission gear 111 is fixed to the outside of the axle of the wheel set 11 away from the handrail. A seeding box 2 is arranged in the middle of the interior of the frame 1. A linkage gear 112 is arranged on the side of the transmission gear 111 near the seeding box 2. The transmission gear 111 can mesh with the linkage gear 112. The linkage gear 112 is rotatably connected to the frame 1. A pulley is fixed to the side of the linkage gear 112 near the frame 1. A discharge shell 24 is fixed to the bottom of the seeding box 2. A feeding wheel 241 is rotatably connected inside the discharge shell 24. Multiple storage troughs are evenly spaced on the outer side of the feeding wheel 241. A pulley is also fixed to the end of the axle of the feeding wheel 241. The pulley of the feeding wheel 241 is connected to the pulley of the linkage gear 112 by a belt. A discharge pipe 242 is fixed to the bottom of the discharge shell 24.

[0039] A pair of feed hoppers 21 are provided at the top of the seed box 2, and a sieve plate 211 is fixed below the feed hoppers 21. The sieve plate 211 is rotatably connected to the seed box 2.

[0040] Among them, the sieve plate 211 can screen the seeds inside the feed hopper 21;

[0041] When planting vegetables, vegetable seeds need to be sown into the soil. To achieve higher efficiency, a seeder is used. When using the seeder, pushing the handle of the frame 1 moves the frame 1, which rolls on the ground via the wheel assembly 11. The frame 1 can be moved to the desired planting area. Then, vegetable seeds are loaded into the seed box 2, reaching the top of the discharge shell 24. After loading the seeds, the frame 1 is moved, and the wheel assembly 11 rolls on the ground. The rotation of the wheel assembly 11 drives the transmission gear 111 to rotate. The transmission gear 111 has teeth on its outer side, one-sixth of its circumference. Therefore, each rotation of the transmission gear 111 drives the linkage gear 1. 12 rotates one-sixth of a turn. At this time, the linkage gear 112 drives the feeding wheel 241 to rotate through the belt and pulley. The outer side of the feeding wheel 241 is provided with six storage troughs, and the storage troughs are matched with the transmission gear 111. The position of the storage trough can be switched every time the transmission gear 111 rotates. When the storage trough of the feeding wheel 241 rotates to the top position of the discharge shell 24, vegetable seeds will enter the inside of the storage trough. Then, as the feeding wheel 241 continues to rotate, the storage trough carries the vegetable seeds into the inside of the discharge pipe 242. At this time, the vegetable seeds fall into the inside of 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. By repeating this process, automatic sowing can be achieved.

[0042] Fertilizer needs to be applied to the seeds during planting. To save fertilization time, the seeds and fertilizer are sown at the same time. When the seeds are placed inside the seeding box 2, fertilizer is put into one of the feed hoppers 21 and the other feed hopper 21. At this time, the sieve plate 211 below the feed hopper 21 can screen the seeds and fertilizer, and can screen out stones or larger fertilizer particles inside the seeds and fertilizer. This can prevent the feeding wheel 241 from being jammed by stones or large fertilizer particles. The two sieve plates 211 are set with different apertures for seeds and fertilizer, which can screen out objects larger than the aperture, thus preventing the feeding wheel 241 from being jammed inside the discharge shell 24.

[0043] like Figures 1 to 9 As shown, a lever 214 is provided at the top of the sieve plate 211, a push block 215 is fixed on one side of the lever 214, 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.

[0044] When the first motor 22 rotates, it drives the lever 214 to slide back and forth on the top of the screen plate 211.

[0045] When the sieve plate 211 screens the seeds and fertilizer inside the feed hopper 21, the feed hopper 21 is in a static 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 lever 214 to slide at the top of the sieve plate 211. At this time, the lever 214 can drive the vegetable seeds and fertilizer inside the feed hopper 21 to move. This allows the vegetable seeds and fertilizer to pass through the mesh of the sieve plate 211 more quickly and prevents the accumulation inside the feed hopper 21.

[0046] like Figures 1 to 9 As shown, a mixing rack 221 is rotatably connected to the middle of the seeding box 2. The end of the shaft of the first motor 22 is fixedly connected to one end of the mixing rack 221. A guide groove 224 is provided on the outer side of the end of the mixing rack 221 away from the first motor 22. A moving plate 222 is rotatably connected to the outer side of the end of the mixing rack 221 away from the first motor 22. A positioning rod is fixed on the side of the seeding box 2 near the moving plate 222. The positioning rod passes through the middle of the moving plate 222. A protrusion 225 is fixed inside the moving plate 222. The protrusion 225 is slidably connected inside the guide groove 224. A connecting plate 223 is provided at the top of the moving plate 222. A second guide rod 226 is fixed at the bottom of the connecting plate 223. The second guide rod 226 is inserted inside the moving plate 222. Pull arms 228 are fixed on both sides of the connecting plate 223.

[0047] When the mixing rack 221 rotates, it drives the moving plate 222 through the guide groove 224 and the protrusion 225, and the moving plate 222 drives the lever 214 to move.

[0048] After the vegetable seeds and fertilizer enter the seeding box 2, they will be mixed to ensure more even sowing. At this time, the first motor 22 rotates and drives the mixing rack 221 to stir and mix the seeds and fertilizer inside the seeding box 2, thus mixing the fertilizer and seeds together.

[0049] As the mixing rack 221 rotates, it drives the guide chute 224 to rotate as well. 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, allowing the protrusion 225 to move back and forth at the end of the mixing rack 221. At this time, the protrusion 225 drives the moving plate 222 to move. The moving plate 222 can be kept stable by the positioning rod. When the moving plate 222 moves, it drives the connecting plate 223 to move through the second guide rod 226. The connecting plate 223 drives the pull arm 228 to push the push block 215. At this time, the push block 215 can drive the lever 214 to slide at 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.

[0050] like Figures 1 to 9 As shown, a guide sleeve 218 is fixed on one side of the feed hopper 21, and a first guide rod 216 is fixed on the side of the push block 215 near the guide sleeve 218. The first guide rod 216 passes through the inside 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.

[0051] When the pull arm 228 moves forward, the push block 215 is pushed by the pull arm 228. The push block 215 will drive the first guide rod 216 to slide inside the guide sleeve 218. At the same time, the spring 217 is squeezed by the push block 215. When the pull arm 228 moves backward, the push block 215 loses the pushing force of the pull arm 228. At this time, the spring 217 pushes the push block 215. The push block 215 drives the lever 214 to slide in the opposite direction at the top of the screen plate 211. The lever 214 slides back and forth, thereby driving the seeds and fertilizers inside the feed hopper 21 to move, making it easier to screen.

[0052] like Figures 1 to 8 As shown, a connecting arm 212 is fixed to the end of the rotating shaft on the side of the sieve plate 211 away from the connecting plate 223. The other end of the connecting arm 212 is rotatably connected to a first pull rod 213. A second motor 23 is installed on the side of the seed box 2 near the first motor 22 through a connecting block. A lead screw 238 is fixed to the end of the rotating shaft of the second motor 23. A lifting frame 231 is connected to the external thread of the lead screw 238. A second pull rod 233 is 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.

[0053] When the lifting frame 231 descends to its lowest position, the sieve plate 211 rotates 90° to both sides at the top of the seeding box 2. When the lifting frame 231 rises to its highest position, the sieve plate 211 rotates 90° towards the center of the seeding box 2 at the top of the seeding box 2.

[0054] After the seeds and fertilizers inside the feed hopper 21 have been screened, the screened objects inside the feed hopper 21 need to be cleaned. At this time, the second motor 23 is started, and the lifting frame 231 is in the highest position at the initial position. The second motor 23 drives the lead screw 238 to rotate, which can drive the lifting frame 231 to move downward. The lifting frame 231 drives the two second pull rods 233 to move downward. At this time, the second pull rods 233 pull 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 screened objects inside the feed hopper 21 can be poured out to the outside, thus completing the cleaning of the inside of the feed hopper 21.

[0055] When it is necessary to reset the screen plate 211 and the feed hopper 21, 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, which allows the second pull rod 233 to drive the connecting arm 212 to rotate in the opposite direction by 90° through the first pull rod 213. At this time, the screen plate 211 and the feed hopper 21 can be reset, which facilitates the cleaning of objects inside the feed hopper 21.

[0056] like Figures 1 to 8 As shown, a baffle 219 is fixed at the bottom of the rotating shaft of the sieve plate 211. The baffle 219 has the same size as the sieve plate 211, and the included angle between the sieve plate 211 and the baffle 219 is 90°.

[0057] After the feed hopper 21 and sieve plate 211 are cleaned, they will remain clean. At this time, the baffle 219 will rotate the top of the seeding box 2 to seal the top of the seeding box 2, which can prevent objects from entering the inside of the seeding box 2 during the sowing process.

[0058] like Figures 1 to 7 As shown, a first arc plate 234 is provided on both sides of the mixing rack 221. The first arc plate 234 is fixedly connected to the inner wall of the seed box 2. A second arc plate 235 is rotatably connected below the first arc plate 234. The ends of the two second arc plates 235 away from the first arc plate 234 can be closely attached.

[0059] When the mixing rack 221 rotates, the ends of the two second arc-shaped plates 235 are pressed together.

[0060] When the mixing rack 221 mixes the seeds and fertilizer inside the seeding box 2, a first arc plate 234 and a second arc plate 235 are set inside the seeding box 2 to facilitate mixing. When the mixing rack 221 rotates, the first arc plate 234 and the second arc plate 235 can restrict the unmixed seeds and fertilizer to the outside of the mixing rack 221. After the mixing rack 221 has finished mixing the seeds and fertilizer, the two second arc plates 235 open to allow the seeds and fertilizer to be fed into the bottom of the seeding box 2, which can prevent the discharge pipe 242 from outputting them to the outside when the seeds and fertilizer are not mixed.

[0061] 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 arc 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.

[0062] When the lifting frame 231 rises to its highest point, the pull frame 236 is at its lowest point inside the guide frame 232. At this time, the pull frame 236 can drive the second arc plate 235 to close, which makes it easier for the mixing frame 221 to mix the materials. When the lifting frame 231 descends to its lowest point, the guide frame 232 guides the pull frame 236 to extend it outward from the seed box 2. At this time, the pull frame 236 can pull the second arc plate 235 to separate, allowing the mixed fertilizer and seeds to be output to the lower area inside the seed box 2, thereby realizing the automatic opening and closing of the second arc plate 235.

[0063] like Figure 7 As shown, a connecting frame 237 is fixed to the bottom end of the second arc plate 235, and the other end of the pull bracket 236 is slidably connected to the connecting frame 237.

[0064] When the pull frame 236 moves, the guide of the seed box 2 will keep it moving on the same horizontal line. In order to prevent interference between the second arc plate 235 and the pull frame 236, a sliding connection is set between the connecting frame 237 and the pull frame 236. The pull frame 236 can slide inside the connecting frame 237 to prevent interference between the second arc plate 235 and the pull frame 236.

[0065] like Figure 5 As shown, a push rod 227 is sleeved on the outside 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 moving plate 222.

[0066] When the feed hopper 21 rotates, it will contact the pull arm 228 and press the pull arm 228 down. At this time, the pull arm 228 drives the second guide rod 226 to extend into the interior of the moving plate 222 through the connecting plate 223, which can realize the automatic repositioning of the pull arm 228. After the feed hopper 21 is reset, the elastic force of the push rod 227 pushes the connecting plate 223 to drive the pull arm 228 to reset, which can realize the automatic reset of the pull arm 228.
