[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 This utility model provides a technical solution: a bean sprout washing and shelling device, including a washing chamber 1, a collection frame 2, a collection plate 3, a motor 4, a filter plate 5, a limiting frame 6, a connecting block 7, a nozzle 8, a load-bearing plate 9, an air guide pipe 10, a blower body 11, a limiting disc 12, a drain pipe 13, a drain valve 14, a connecting plate 15, a connecting bolt 16, a support plate 17, a conveyor belt 18, a limiting plate 19, a guide roller 20, a connecting seat 21, a load-bearing column 22, a base plate 23, a self-locking wheel 24, a guide rod 25, and a guide roller 26.
[0029] Specific examples Figure 1 , Figure 3 and Figure 5 As shown, firstly, the connecting seats 21 at the bottom of the load-bearing column 22 are placed at equal intervals on the upper side of the base plate 23. After the connecting seats 21 are placed on the base plate 23, they are welded to the base plate 23, so that the connecting seats 21 connected to the bottom of the load-bearing column 22 are limited on the base plate 23. After the connecting seats 21 at the bottom of the load-bearing column 22 are connected to the base plate 23, the cleaning chamber 1 is placed stably on the connecting seats 21 on the upper side of the load-bearing column 22. The connecting seats 21 have a trapezoidal structure, and the bottom of the cleaning chamber 1 is connected to the upper side of the load-bearing column 22. After the connecting seat 21 makes contact, the connecting seat 21 on the upper side of the load-bearing column 22 is set at equal intervals at the bottom of the cleaning chamber 1. The connecting seat 21 is symmetrically arranged about the inner load-bearing column 22. Similarly, after welding the connecting seat 21 on the upper side of the load-bearing column 22 to the cleaning chamber 1, the connecting seat 21 on the upper side of the load-bearing column 22 is limited to the cleaning chamber 1. At this time, when the cleaning chamber 1 is pushed, the self-locking wheel 24 on the lower side of the base plate 23 will roll on the ground. When the self-locking wheel 24 rolls to the appropriate position, the pushing of the cleaning chamber 1 stops.
[0030] Next, a connecting plate 15 is placed inside the cleaning chamber 1, with its outer wall in contact with the inner wall of the cleaning chamber 1. Connecting plates 15 are placed on both the left and right sides of the cleaning chamber 1, symmetrically arranged about the center line of the cleaning chamber 1. Then, connecting bolts 16 are manually screwed onto the contact points between the connecting plates 15 and the cleaning chamber 1. Connecting bolts 16 have a threaded structure on their exterior. When the connecting bolts 16 are tightened, the connection gap between the connecting plates 15 and the cleaning chamber 1 shortens. Both the connecting plates 15 and the cleaning chamber 1 are threadedly connected to the connecting bolts 16. The connecting bolts 16 are evenly spaced on the upper side of the connecting plates 15. The connecting plate 15 is fastened to the cleaning chamber 1 by the connecting bolt 16. The support plate 17 is symmetrically arranged about the outside of the connecting plate 15. The guide rod 25 passes through the inside of the support plate 17. The guide rod 25 is symmetrically arranged about the center line of the guide roller 26. The guide roller 26 passes through the inside of the conveyor belt 18 and is distributed at both ends of the conveyor belt 18. At the same time, the inside of the conveyor belt 18 is passed through by the guide roller 20. The upper side of the conveyor belt 18 is set at the bottom of the limiting plate 12. The bean sprout washing and shelling device is installed, which facilitates the quick assembly and movement of the bean sprout washing and shelling device.
[0031] Specific examples Figure 1 and Figure 2 As shown, after the bean sprout washing and shelling device is assembled, ensure that the drain pipe 13 on the right side of the washing chamber 1 is closed. The drain valve 14 in the drain pipe 13 isolates the internal space of the washing chamber 1 from the external space. Fill the washing chamber 1 with clean water until the water level exceeds the upper end of the limit plate 12. Then, connect the power to the motor 4 located on the front side of the guide rod 25. After the motor 4 is connected to the power, it is turned on. After the motor 4 is turned on, it drives the guide rod 25 connected to the rear side. The guide rod 25 is symmetrically arranged about the center line of the guide roller 26. The guide rod 25 passes through the interior of the support plate 17 and slides through the washing chamber 1 when the guide rod 25 rotates. The guide rod 25 drives the inner guide roller 26 to move. The guide roller 26 passes through the interior of the conveyor belt 18. Friction is generated between the outer wall of the guide roller 26 and the conveyor belt 18. The conveyor belt 18 moves under the drive of the guide roller 26.
[0032] The upper side of the conveyor belt 18 is positioned below the limiting plate 12 during installation and contacts the bottom surface of the limiting plate 12. The inner end of the cleaning chamber 1 is equipped with symmetrically distributed limiting plates 12 on the left side. The limiting plates 12 have a disc-shaped structure. Under the action of the limiting plates 12, a portion of the conveyor belt 18 extends underwater for horizontal positioning. When the conveyor belt 18 moves, the upper side of the conveyor belt 18 experiences sliding friction with the bottom end of the limiting plate 12. Simultaneously, the conveyor belt 18 interacts with the guide roller 26 and the guide roller 20. All are connected by sliding. The limiting plates 19 are evenly spaced on the conveyor belt 18, which has a hollow structure. When the conveyor belt 18 is conveying, the limiting plates 19 on the outside of the conveyor belt 18 move with it. Bean sprouts are placed in sequence at the left end of the conveyor belt 18. After the bean sprouts come into contact with the conveyor belt 18, they are limited between two sets of adjacent limiting plates 19, thus following the conveyor belt 18 for conveying. This facilitates the limiting and conveying of bean sprouts by the bean sprout washing and shelling device.
[0033] Specific examples Figure 1 and Figure 4 As shown, before starting the motor 4, align the limiting frame 6 on the upper side of the collection frame 2 with the center of the cleaning chamber 1. At this time, the collection plate 3 inside the collection frame 2 is close to the left end of the conveyor belt 18. The right side of the collection frame 2 is equipped with a filter plate 5 parallel to the collection plate 3. The filter plate 5 inside the collection frame 2 is close to the right end of the conveyor belt 18. The filter plate 5 has a hollow structure, and the diameter of the holes inside the collection plate 3 is larger than the size of the holes inside the filter plate 5. The longitudinal section of the limiting frame 6 is U-shaped. Pressing the limiting frame 6 causes friction between the front and rear outer walls of the collection frame 2 under the limiting frame 6 and the inner wall of the cleaning chamber 1. The collection frame 2 and the cleaning chamber 1 are slidably connected. When the bottom end of the limiting frame 6 contacts the top end of the cleaning chamber 1, the limiting frame 6 and the cleaning chamber 1 are engaged, and the collection frame 2 is restricted inside the cleaning chamber 1. At this time, the water level inside the cleaning chamber 1 is between the highest and lowest points of the collection plate 3.
[0034] Then, the load-bearing plate 9 is engaged on the upper left side of the cleaning chamber 1, so that the connecting block 7 on the lower side of the load-bearing plate 9 is engaged on the front and rear inner walls of the cleaning chamber 1. The nozzle 8 connected to the left side of the connecting block 7 is directly opposite the conveyor belt 18 and is set perpendicular to the conveyor belt 18. When the bean sprouts are placed at the left end of the conveyor belt 18, the bean sprouts will be conveyed by the conveyor belt 18 under the limit of the limiting plate 19. After the blower body 11 is turned on, the blower body 11 blows air to the nozzle 8 through the air guide pipe 10. When the air force is large, it will cause the connection between the bean sprout shell and the bean sprout directly opposite the nozzle 8 to loosen, and the bean sprout shell will no longer just wrap around the bean sprout.
[0035] The conveyor belt 18 continues to transport the bean sprouts. When the bean sprouts reach below the liquid surface in the washing chamber 1 via the conveyor belt 18, the loosened bean sprout shells will float on the water surface due to their light weight. At this time, the bean sprout shells will gather in the space at the left end of the washing chamber 1. As the conveyor belt 18 continues to transport the bean sprouts, the water inside the washing chamber 1 will flow inside the washing chamber 1, thereby pushing the bean sprout shells through the holes inside the collecting plate 3 to the collecting frame 2. The size of the holes inside the collecting plate 3 is larger than the diameter of the bean sprout shells.
[0036] Meanwhile, the size of the holes inside the collecting plate 3 is larger than that inside the filter plate 5, so that the bean sprout shells that enter the collecting frame 2 remain inside the collecting frame 2. The water flows through the filter plate 5 and continues to flow in the washing chamber 1, and the bean sprouts and bean sprout shells are separated until the bean sprouts are conveyed to the right end by the conveyor belt 18. The bean sprouts can then be manually inspected. This makes it easy to realize the bean sprout washing and shelling device to filter and remove the bean sprout shells. This is the usage method of the bean sprout washing and shelling device.
