[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a vibration cleaning component. When the rotating drum rotates, the fixed rack fixed to the docking plate will not rotate with the rotating drum, so that when the docking gear on the crankshaft rotates to a position meshing with the fixed rack, the docking gear will rotate with the fixed rack, thereby driving the crankshaft to rotate. The rotation of the crankshaft will drive the swing rod to swing back and forth, so that the swing rod stretches the sliding frame to swing back and forth on the positioning plate. Since the seeds are blocked on one side by the bottom plate, that is, the seeds are distributed inside the sliding frame, the reciprocating swing of the sliding frame will push the seeds inside to swing back and forth below the liquid level, and the back and forth swinging of the seeds makes the surface cleaning effect better. When the docking gear rotates to disengage from the meshing with the fixed rack, the crankshaft no longer rotates. At this time, the seeds inside the positioning plate will also slide down along the bottom plate due to their too high position, and then enter the lower positioning plate to continue to swing. During the cleaning process, the seeds are not only directly sprayed and soaked, but also the seeds are fully cleaned by tossing the seeds during the spraying process.

[0016] See also Figure 1-7 The present invention provides a technical solution: a device for washing and draining crop seeds, comprising a washing cylinder 4, wherein the top of the washing cylinder 4 is rotatably connected to a rotating cylinder 2, a water inlet pipe 3 is fixedly connected to the left wall of the washing cylinder 4, the top of the water inlet pipe 3 is rotatably connected to the rotating cylinder 2, a docking plate 14 is rotatably connected to the right wall of the rotating cylinder 2, a feed pipe 1 is fixedly connected to the right end of the docking plate 14, the bottom of the feed pipe 1 is fixedly connected to the washing cylinder 4, a conveying frame 5 is arranged at the rear side of the washing cylinder 4, a drying mechanism 6 is fixedly connected to the top of the conveying frame 5, a vibration washing component is arranged inside the rotating cylinder 2, and the vibration washing component is used for vibrating the seeds when washing the crop seeds, so as to improve the cleaning effect of the seeds; When the above scheme is put into actual use, the seeds to be cleaned are added into the rotating drum 2 through the feed pipe 1, and the clean water in the cleaning drum 4 is pumped into the rotating drum 2 through the water inlet pipe 3 to spray and rinse the seeds. At the same time, the rotating drum 2 is rotated to achieve the effect of rolling and rinsing the seeds. While the rotating drum 2 is rotating, the vibrating cleaning component will move the seeds in the rotating drum 2 to fully clean them. After cleaning, the seeds enter the conveying rack 5 from the rotating drum 2 and are transported with the conveying rack 5. During transportation, the seeds are dried by the drying mechanism 6. After drying, the seeds can be collected. The advantage of this is that the seeds are not only cleaned by direct spraying and soaking during the cleaning process, but the surface of the seeds is fully cleaned by moving the seeds during the spraying process.

[0017] As a further solution of the present invention, the vibration cleaning assembly includes a bottom plate 17, a plurality of bottom plates 17 equidistantly distributed are fixedly connected to the inner wall of the rotating cylinder 2, a positioning plate 26 is fixedly connected to one end of the bottom plate 17, a sliding frame 16 is slidably connected to the positioning plate 26, a swing rod 25 is rotatably connected to one end of the sliding frame 16, a crankshaft 15 is rotatably connected inside the rotating cylinder 2, one end of the swing rod 25 is rotatably connected to the crankshaft 15, a fixed rack 27 is fixedly connected to the side wall of the docking plate 14, a docking gear 28 meshing with the fixed rack 27 is provided on the rotating cylinder 2, one end of the crankshaft 15 slides through the rotating cylinder 2 and is fixedly connected to the docking gear 28, a spray pipe is provided inside the rotating cylinder 2, and one end of the spray pipe is fixedly connected to the water inlet pipe 3; When the above scheme is put into practical use, when the seeds are washed inside the rotating drum 2, when the rotating drum 2 rotates, the bottom plate 17 will block the rotation of the seeds. When the bottom plate 17 rotates to the top of the rotating drum 2, the seeds will fall from the top of the rotating drum 2 along the bottom plate 17 to the bottom of the rotating drum 2 under the action of the seeds, and then be blocked by another bottom plate 17. The above action is repeated as the rotating drum 2 rotates. The purpose of this is to move the soaked seeds above the liquid surface and then fall below the liquid surface again. The cleaning effect of the seeds is further improved by the impact of the seeds on the liquid surface. When the seeds fall from a high place, they will contact the spraying equipment to be fully sprayed. When the rotating drum 2 rotates, the fixed rack 27 fixed to the docking plate 14 will not rotate with the rotating drum 2, so that when the docking gear 28 on the crankshaft 15 rotates to a position meshing with the fixed rack 27, the docking gear 28 will rotate with the fixed rack 27, thereby driving the crankshaft 15 to rotate. The rotation of the crankshaft 15 will drive the swing rod 25 to swing back and forth, so that the swing rod 25 stretches the sliding frame 16 to swing back and forth on the positioning plate 26. Since the seeds are blocked on one side by the bottom plate 17, that is, the seeds are distributed inside the sliding frame 16, the reciprocating swing of the sliding frame 16 will push the seeds inside to swing back and forth below the liquid level, and the back and forth swinging of the seeds makes the surface cleaning effect better. When the docking gear 28 rotates to disengage from the fixed rack 27, the crankshaft 15 no longer rotates. At this time, the seeds inside the positioning plate 26 will also slide down along the bottom plate 17 due to their too high position, and then enter the lower positioning plate 26 to continue swinging until the seeds are completely cleaned.

[0018] As a further solution of the present invention, a plurality of sliding plates 18 corresponding to the bottom plate 17 are provided on the outer wall of the rotating cylinder 2, and a docking block 24 is fixedly connected to the outer wall of the sliding plate 18, and a second fixed block 23 is fixedly connected to the rotating cylinder 2, and one end of the second fixed block 23 is fixedly connected to a connecting shaft 22, and a fixed sleeve 20 is slidably sleeved on the connecting shaft 22, and one end of the fixed sleeve 20 is fixedly connected to a first fixed block 19, and one end of the first fixed block 19 is fixedly connected to the outer wall of the rotating cylinder 2, and a second spring for resetting the fixed sleeve 20 is sleeved on the connecting shaft 22 21, a slide groove 29 is provided on the inner wall of the conveying frame 5, a fixed plate 10 is slidably connected inside the slide groove 29, a fixed shaft 13 is fixedly connected to the top of the fixed plate 10, a connecting plate 12 is slidably connected to the fixed shaft 13, a first spring 11 for resetting the connecting plate 12 is sleeved on the fixed shaft 13, a driving cylinder 30 is fixedly connected to the side wall of the conveying frame 5, an output shaft of the driving cylinder 30 is fixedly connected to the fixed plate 10, the inner wall of the sliding plate 18 can be completely fitted with the outer wall of the rotating cylinder 2, and a discharge trough corresponding to the sliding plate 18 is provided on the rotating cylinder 2; When the above scheme is put into practical use, after the seeds inside the rotating drum 2 are cleaned, the fixed plate 10 is pushed to slide toward the front of the conveying frame 5 by driving the air cylinder 30, so that when the rotating drum 2 continues to rotate, the docking block 24 on the surface of the sliding plate 18 can contact the connecting plate 12, and the pressure after the connecting plate 12 and the docking block 24 contact will squeeze the second spring 21 so that the docking block 24 cannot continue to slide with the rotating drum 2, that is, the sliding plate 18 is fixed, and the fixed sleeve 20 compresses the second spring 21 to slide on the connecting shaft 22, so that one side of the rotating drum 2 is opened, and the rotating drum 2 continues to rotate so that the discharge slot on the rotating drum 2 is gradually opened, and the gravity inside the rotating drum 2 under the action of gravity will enter the inside of the conveying frame 5 along the discharge slot, and at this time the seed height is above the liquid level, and the excess water on the seeds will be drained off, and the seeds enter the conveying frame 5 and slide along with the conveying frame 5, and the seeds are dried by the drying mechanism 6; When the sliding plate 18 compresses the second spring 21 to the maximum value, the docking block 24 will push the connecting plate 12 to slide upward and stretch the first spring 11. Since the docking block 24 rotates around the rotating cylinder 2, and the connecting plate 12 slides vertically upward, when the docking block 24 rotates to push the connecting plate 12 to slide upward for a distance, the docking block 24 will break away from the contact with the connecting plate 12. After separation, the second spring 21 will push the sliding plate 18 to return to its original position, and the first spring 11 will stretch the connecting plate 12 to return to its original position. At this time, the seeds inside the rotating cylinder 2 have been transferred to the inside of the conveying rack 5, and then seeds are added to the inside of the rotating cylinder 2 through the feeding pipe 1 for cleaning. The seeds can be rinsed again by driving the cylinder 30 to stretch the fixed plate 10 backward and return it to its original position.

[0019] As a further solution of the present invention, a collecting assembly 8 is fixedly connected to the bottom of the front end of the conveying frame 5, and a return pipe 7 is fixedly connected to the bottom of the collecting assembly 8, and the top opening of the return pipe 7 is located directly above the conveying frame 5; When the above scheme is put into actual use, when the seeds enter the conveying frame 5 from the discharge trough on the rotating cylinder 2, the seeds dropped from a high place may bounce to the outside of the conveying frame 5, and the seeds are further collected by the collecting component 8. The collected clean seeds flow back to the top of the conveying frame 5 through the reflux pipe 7, ensuring that many seeds will not be scattered during transportation.

[0020] As a further solution of the present invention, the front end of the drying mechanism 6 is fixedly connected to a sub-screen plate 9 extending downward; When the above scheme is put into actual use, the thickness of the seeds on the conveying rack 5 is limited by the sieve plate 9, so that the seeds with a thicker accumulation are flattened. This makes the seeds on the conveying rack 5 more effectively dried by the drying mechanism 6, avoiding the poor seed drying effect caused by seed accumulation.

[0021] Working principle: the seeds to be cleaned are added into the rotating drum 2 through the feed pipe 1, and the clean water in the cleaning drum 4 is pumped into the rotating drum 2 through the water inlet pipe 3 to spray and rinse the seeds. At the same time, the rotating drum 2 is rotated to achieve the effect of rolling and washing the seeds. When the rotating drum 2 rotates, the bottom plate 17 will block the rotation of the seeds. When the bottom plate 17 rotates to the top of the rotating drum 2, the seeds will fall from the high place of the rotating drum 2 to the bottom of the rotating drum 2 along the bottom plate 17 under the action of the seeds, and then be blocked by another bottom plate 17, and the above action will be repeated as the rotating drum 2 rotates; When the rotating drum 2 rotates, the fixed rack 27 fixed to the docking plate 14 will not rotate with the rotating drum 2, so that when the docking gear 28 on the crankshaft 15 rotates to a position meshing with the fixed rack 27, the docking gear 28 will rotate with the fixed rack 27, thereby driving the crankshaft 15 to rotate. The rotation of the crankshaft 15 will drive the swing rod 25 to swing back and forth, so that the swing rod 25 stretches the sliding frame 16 to swing back and forth on the positioning plate 26. Since the seeds are blocked on one side by the bottom plate 17, that is, the seeds are distributed inside the sliding frame 16, the reciprocating swing of the sliding frame 16 will push the seeds inside to swing back and forth below the liquid surface, and the seeds The back and forth swinging makes the surface cleaning effect better. When the docking gear 28 rotates to disengage from the fixed rack 27, the crankshaft 15 stops rotating. At this time, the seeds inside the positioning plate 26 will slide down along the bottom plate 17 due to the excessive position, and then enter the lower positioning plate 26 to continue swinging until the seeds are completely cleaned. When the seeds inside the rotating drum 2 are cleaned, the fixed plate 10 is pushed to slide toward the front of the conveying frame 5 by driving the cylinder 30, so that when the rotating drum 2 continues to rotate, the docking block 24 on the surface of the sliding plate 18 can contact the connecting plate 12, and the connecting plate 12 contacts the docking block 24. The pressure after will squeeze the second spring 21 so that the docking block 24 cannot continue to slide with the rotating drum 2, that is, the sliding plate 18 is fixed, and the fixed sleeve 20 compresses the second spring 21 to slide on the connecting shaft 22, so that one side of the rotating drum 2 is opened, and the rotating drum 2 continues to rotate so that the discharge groove on the rotating drum 2 gradually opens. Under the action of gravity, the gravity inside the rotating drum 2 will enter the inside of the conveying rack 5 along the discharge groove, and at this time the seed height is above the liquid surface, the excess water on the seeds will be drained off, and the seeds enter the conveying rack 5 and slide with the conveying rack 5. The seeds are dried by the drying mechanism 6. After the second spring 21 reaches the maximum value, the docking block 24 will push the connecting plate 12 to slide upward and stretch the first spring 11. Since the docking block 24 rotates around the rotating cylinder 2, and the connecting plate 12 slides vertically upward, when the docking block 24 rotates to push the connecting plate 12 to slide upward for a distance, the docking block 24 will break away from the contact with the connecting plate 12. After separation, the second spring 21 will push the sliding plate 18 to return to its original position, and the first spring 11 will stretch the connecting plate 12 to return to its original position. At this time, the seeds inside the rotating cylinder 2 have been transferred to the inside of the conveying rack 5, and then seeds are added to the inside of the rotating cylinder 2 through the feeding pipe 1 for cleaning.
