Abstract
Description
Technical Field
[0001] This invention belongs to the field of yam processing screening technology, specifically a grading and screening device for yam processing. Background Technology
[0002] Yam, formally known as Chinese medicinal yam, originates from the dried rhizome of the Dioscorea opposita plant, belonging to the Dioscoreaceae family. The best time to harvest is November and December. During harvesting, the root head is first cut off, the rhizome is washed clean of soil, and the outer skin is scraped off with a bamboo knife. Then, it is sun-dried or oven-dried to obtain raw yam. Next, large, high-quality raw yams are selected for further processing. They are first soaked in water to ensure even water absorption, then slightly heated and covered with a cotton quilt to thoroughly absorb moisture. Next, they are kneaded on a wooden board into a cylindrical shape, the ends are trimmed, and finally, they are sun-dried again and polished to obtain smooth yam, which has a more attractive appearance and more prominent medicinal value.
[0003] Yam needs to be cut during processing to facilitate packaging. However, during the cutting process, some yams are shredded by the cutting disc. If these shredded yam pieces are not processed promptly and packaged directly, the quality of the packaged product will be affected. Therefore, the yam pieces must be sieved to ensure their quality.
[0004] Current technology suffers from insufficient sieving precision for yams and lacks effective grading and sieving functions, resulting in unsatisfactory sieving results.
[0005] Therefore, the present invention provides a grading and screening device for yam processing. Summary of the Invention
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A grading and screening device for yam processing, comprising a screening box; a feed inlet is connected to the top of the screening box; a first screening screen is slidably connected to the middle of the screening box; a second screening screen is provided at the bottom of the first screening screen; the second screening screen is slidably connected to the first screening screen; a vibration motor is fixedly connected to one end of the first and second screening screens; the vibration motor is fixedly connected to the screening box; and a discharge port is opened at the other end of the first and second screening screens. During operation, yam is fed into the screening box through the feed inlet, and the vibration motor is activated to drive the first and second screening screens to vibrate. The first and second screening screens are made of soft silicone, which is soft and elastic, effectively cushioning the impact. The impact force of the yam rolling maximizes the protection of the yam's components. The first screening screen has larger mesh sizes than the second screening screen, enabling graded screening. This allows coarser yams to roll smoothly along the screen without getting stuck, while also enabling finer yams to quickly pass through the mesh and fall into their corresponding layers, preventing stagnation and accumulation. The yams will remain at one end of the first and second screening screens and finally be removed from the discharge port. By setting up the first and second screening screens, a vibrating motor, and the discharge port, the screens tilt under vibration and slowly roll. Yams whose diameter does not conform to the current screening layer continue to move forward, while those that do conform naturally fall to the next layer. Ultimately, yams of different sizes are discharged in an orderly manner from the discharge ports at the end of each layer, achieving the effect of graded screening and improving screening efficiency and accuracy.
[0008] Preferably, a first motor is fixedly connected to one side of the feed inlet, and a rotating shaft is fixedly connected to one end of the first motor. The rotating shaft is rotatably connected to the feed inlet, and multiple material distribution plates are fixedly connected to the outside of the rotating shaft. During operation, when material is fed into the feed inlet, the first motor will start and drive the rotating shaft to rotate, which in turn drives the material distribution plates to rotate inside the feed inlet. The material distribution plates guide the yam to be distributed, so that the yam fed into the screening box can enter evenly, reducing the possibility of blockage at the first screening screen at the bottom of the feed inlet. By setting up the first motor, rotating shaft, and material distribution plates, the effect of uniform feeding is achieved, reducing the possibility of congestion at the first and second screening screens in the screening box, which would affect the screening efficiency.
[0009] Preferably, the bottom of the second screening screen is provided with a collection trough, and one end of the collection trough is provided with a discharge port. The discharge port is opened on the surface of the screening box, and a cover plate is snapped into the middle of the discharge port. During operation, the collection trough collects the mixed impurities in the yam. Along with the screening action of the first and second screening screens, it can simultaneously receive the debris, rootlets and other impurities generated during the grading process without additional cleaning. After the collection trough is full, the cover plate can be opened to remove the impurities in the collection trough from the discharge port.
[0010] Preferably, one end of the discharge port is provided with a discharge pipe, which is fixedly connected to the screening box. A slot is opened at the top of the discharge pipe, and a locking block is slidably connected in the slot. Both the slot and the locking block are L-shaped. During operation, the locking block is inserted into the slot to block the discharge pipe, reducing the possibility of yams falling off the discharge pipe when the first and second screening screens are screening the yams. The locking block can be removed from the slot to collect the sifted yams. The locking block is L-shaped. When the locking block is turned to the side and inserted into the discharge pipe, the yams on the first and second screening screens can be pulled outwards, making it easier to collect the sifted yams.
[0011] Preferably, a first magnetic strip is fixedly connected to the bottom of the discharge pipe, and a second magnetic strip is fixedly connected to the bottom of the card block. The first magnetic strip and the second magnetic strip are arranged correspondingly. During operation, the first magnetic strip and the second magnetic strip work together to attract each other, which can enhance the connection and fixation effect between the discharge pipe and the card block and reduce the risk of losing the card block.
[0012] Preferably, one end of the card block is provided with multiple brushes, which are fixedly connected to the card block. During operation, after the screening and collection work is completed, the card block is moved to align the brushes with the first and second screening screens, which can clean the first and second screening screens and reduce the clogging of the screens caused by the accumulation of yam.
[0013] The beneficial effects of this invention are as follows: 1. The grading and screening device for yam processing described in this invention comprises a first screening screen, a second screening screen, a vibrating motor, and a discharge port. Under the action of vibration, the first and second screening screens are inclined and slowly roll. Yams whose diameter does not conform to the current screening layer continue to move forward, while those that do conform naturally fall to the lower layer. Finally, yams of different specifications are discharged in an orderly manner from the discharge port at the end of each layer, thereby achieving the effect of grading and screening and improving screening efficiency and accuracy.
[0014] 2. The grading and screening device for yam processing described in this invention achieves uniform feeding by setting a first motor, a rotating shaft, and a material distribution plate, thereby reducing the clogging of the first and second screening screens in the screening box and reducing the impact on screening efficiency.

Detailed Implementation
[0017] 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.
[0018] like Figures 1 to 2 As shown in the embodiment of the present invention, a grading and screening device for yam processing includes a screening box 1; the top of the screening box 1 is connected to an inlet 11, a first screening screen 12 is slidably connected to the middle of the screening box 1, a second screening screen 13 is provided at the bottom of the first screening screen 12, the second screening screen 13 is slidably connected to the first screening screen 12, a vibration motor 14 is fixedly connected to one end of the first screening screen 12 and the second screening screen 13, the vibration motor 14 is fixedly connected to the screening box 1, and an outlet 15 is opened at the other end of the first screening screen 12 and the second screening screen 13. During operation, yam is fed into the screening box 1 through the inlet 11, and the vibration motor 14 is started to drive the first screening screen 12 and the second screening screen 13 to vibrate. The first screening screen 12 and the second screening screen 13 are made of soft silicone, which is soft and elastic, and can... To effectively buffer the impact force of the yam during rolling and protect the yam's composition to the greatest extent, the first screening screen 12 has a larger screen aperture than the second screening screen 13. This enables graded screening, allowing coarser yams to roll smoothly along the screen without getting stuck, while also enabling finer yams to quickly pass through the screen apertures and fall into the corresponding layer, avoiding stagnation and accumulation. The yams will stay at one end of the first screening screen 12 and the second screening screen 13, and finally be removed from the discharge port 15. By setting up the first screening screen 12, the second screening screen 13, the vibrating motor 14, and the discharge port 15, the first screening screen 12 and the second screening screen 13 are tilted under vibration and slowly roll. Yams whose diameter does not conform to the current screen layer continue to move forward, while those that conform naturally fall into the lower layer. Finally, yams of different sizes are discharged in an orderly manner from the discharge port 15 at the end of each layer, achieving the effect of graded screening and improving screening efficiency and accuracy.
[0019] like Figures 1 to 3As shown, a first motor 2 is fixedly connected to one side of the feed inlet 11, and a rotating shaft 21 is fixedly connected to one end of the first motor 2. The rotating shaft 21 is rotatably connected to the feed inlet 11, and multiple material distribution plates 22 are fixedly connected to the outside of the rotating shaft 21. During operation, when feeding material into the feed inlet 11, the first motor 2 will start and drive the rotating shaft 21 to rotate, which in turn drives the material distribution plates 22 to rotate inside the feed inlet 11. The material distribution plates 22 guide the yam to be distributed, so that the yam put into the screening box 1 can enter evenly, reducing the blockage at the first screening screen 12 at the bottom of the feed inlet 11. By setting the first motor 2, rotating shaft 21, and material distribution plates 22, the effect of uniform feeding is achieved, reducing the congestion of the first screening screen 12 and the second screening screen 13 in the screening box 1, which affects the screening efficiency.
[0020] like Figures 1 to 3 As shown, the bottom of the second screening screen 13 is provided with a collection trough 3, and one end of the collection trough 3 is provided with a discharge port 31. The discharge port 31 is opened on the surface of the screening box 1, and a cover plate 32 is snapped into the middle of the discharge port 31. During operation, the collection trough 3 collects the mixed impurities in the yam. Along with the screening action of the first screening screen 12 and the second screening screen 13, it can simultaneously receive the debris, rootlets and other impurities generated during the grading process without additional cleaning. After the collection trough 3 is full, the cover plate 32 can be opened to remove the impurities in the collection trough 3 from the discharge port 31.
[0021] like Figures 2 to 4 As shown, one end of the discharge port 15 is provided with a discharge pipe 4, which is fixedly connected to the screening box 1. The top of the discharge pipe 4 is provided with a slot 41, and a locking block 42 is slidably connected in the slot 41. Both the slot 41 and the locking block 42 are L-shaped. During operation, the locking block 42 is inserted into the slot 41 to block the discharge pipe 4, reducing the possibility of yams falling off the discharge pipe 4 when the first screening screen 12 and the second screening screen 13 screen the yams. The locking block 42 can be removed from the slot 41 to collect the sifted yams. The locking block 42 is L-shaped. When the locking block 42 is turned to the side and inserted into the discharge pipe 4, the yams on the first screening screen 12 and the second screening screen 13 can be pulled outwards, making it easier to collect the sifted yams.
[0022] like Figures 4 to 5 As shown, a first magnetic stripe 5 is fixedly connected to the bottom of the discharge pipe 4, and a second magnetic stripe 51 is fixedly connected to the bottom of the card block 42. The first magnetic stripe 5 and the second magnetic stripe 51 are set in correspondence. When working, the first magnetic stripe 5 and the second magnetic stripe 51 work together to attract each other, which can strengthen the connection and fixation effect between the discharge pipe 4 and the card block 42 and reduce the risk of losing the card block 42.
[0023] like Figure 5As shown, one end of the card block 42 is provided with multiple brushes 6. The brushes 6 are fixedly connected to the card block 42. During operation, after the screening and collection work is completed, the card block 42 is moved to align the brushes 6 with the first screening screen 12 and the second screening screen 13, which can clean the first screening screen 12 and the second screening screen 13 and reduce the clogging of the screens on the first screening screen 12 and the second screening screen 13 caused by the accumulation of yam.
[0024] Working principle: Yam is fed into screening box 1 through inlet 11. Vibration motor 14 starts and drives the first screening screen 12 and the second screening screen 13 to vibrate. The first screening screen 12 and the second screening screen 13 are made of soft silicone, which is soft and elastic, and can effectively buffer the impact force when the yam rolls, protecting the yam phase to the greatest extent. The screen size of the first screening screen 12 is larger than that of the second screening screen 13, which can achieve graded screening. It can make the coarser yam roll smoothly along the screen without getting stuck, and can also make the finer yam quickly pass through the screen holes and fall into the corresponding level, avoiding retention and accumulation. The yam will stay at one end of the first screening screen 12 and the second screening screen 13, and finally be taken out from the outlet 15. By setting the first screening screen... The first screening screen 12, the second screening screen 13, the vibrating motor 14, and the discharge port 15 are inclined under the action of vibration. The first screening screen 12 and the second screening screen 13 slowly roll. Yams whose diameter does not conform to the current screening layer continue to move forward, while those that do conform naturally fall into the lower layer. Finally, yams of different specifications are discharged in an orderly manner from the discharge port 15 at the end of each layer, achieving the effect of graded screening and improving screening efficiency and accuracy. When feeding into the feed port 11, the first motor 2 will start and drive the rotating shaft 21 to rotate, which in turn drives the dividing plate 22 to rotate in the feed port 11. The dividing plate 22 divides and guides the yams, so that the yams fed into the screening box 1 can enter evenly and reduce the blockage at the bottom of the first screening screen 12 of the feed port 11. By setting up the first motor 2, rotating shaft 21, and material distribution plate 22, a uniform feeding effect is achieved, reducing the possibility of clogging of the first screening screen 12 and the second screening screen 13 in the screening box 1, which would affect the screening efficiency. The collection trough 3 collects mixed impurities from the yam. Along with the screening action of the first screening screen 12 and the second screening screen 13, it can simultaneously receive impurities such as broken pieces and rootlets generated during the grading process, without the need for additional cleaning. When the collection trough 3 is full, the cover plate 32 can be opened to remove the impurities from the discharge port 31. The locking block 42 is inserted into the locking slot 41 to block the discharge pipe 4, reducing the possibility of the yam falling out of the discharge pipe 4 when the first screening screen 12 and the second screening screen 13 are screening the yam. The yam can be collected after screening by discharging the card block 42. The card block 42 is L-shaped. When the card block 42 is turned to the side and inserted into the discharge pipe 4, the yam on the first screening screen 12 and the second screening screen 13 can be pulled outward, which is convenient for collecting the sieving yam. The first magnetic strip 5 and the second magnetic strip 51 work together to attract and strengthen the connection and fixation between the discharge pipe 4 and the card block 42, reducing the risk of losing the card block 42. After the screening and collection work is completed, the card block 42 is moved and the brush 6 is aligned with the first screening screen 12 and the second screening screen 13 to clean the first screening screen 12 and the second screening screen 13, reducing the clogging of the screens caused by the accumulation of yam.
