Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automatic screening and classification, and specifically to an automatic screening and classification device for ginseng fine processing and its usage method. Background Art
[0002] Ginseng is a perennial herbaceous plant of the Araliaceae family and the genus Panax. Ginseng also belongs to traditional Chinese medicine materials. In the process of ginseng production, first, the ginseng is washed and dried, then dehydrated and dried, and finally sliced and graded. When grading, screening equipment is needed to classify the ginseng. Generally, large pharmaceutical factories use color sorters, while small factories or individuals still use simple screening equipment for screening.
[0003] In the process of using the existing color sorter, since it utilizes the different absorption or reflection intensities of material particles and different-color particles to specific light, the light signal is converted into an electrical signal and amplified through a photoelectric conversion device, then the voltage value is picked and recognized, and finally the injection valve is driven to instantaneously blow the different-color particles, so as to achieve the separation of material particles and different-color particles. However, in actual use, if some ginseng adheres to some agglomerated different-color dust or impurity particles on the surface, it will cause the surface brightness to be insufficient, resulting in a significant decrease in the recognition rate of the color sorter, easily averaging the product quality during the screening process, mixing high-quality and low-quality products together, and consuming a larger amount of compressed air. At the same time, due to transportation and processing problems in some ginseng, a large number of small fragments are generated during the crushing of some ginseng. When these small fragments pass through the rejection device of the color sorter, they will be mixed with larger ginseng, increasing the working frequency of the light-sensitive camera in the color sorter, easily causing the load of the driving circuit of the color sorter to be larger, resulting in damage to the fuse or the injection valve coil and the driving circuit. For this reason, we propose an automatic screening and classification device for ginseng fine processing and its usage method. Summary of the Invention

A second spring is sleeved on each movable rod. The common end of a plurality of movable rods is fixedly connected to a pressing plate. One end of the bottom of the pressing plate is fixedly installed with a first wedge plate. The two sides inside the guide groove are slidably connected with second wedge plates. A grinding roller is movably connected between the two second wedge plates. An inclined plate is fixedly installed at the top of the guide groove, and a grinding plate is fixedly installed at the bottom of the guide groove.
[0006] Preferably, the grinding plate is located directly below the inclined plate. A first spring is fixedly installed inside each second wedge plate. A lifting block is fixedly connected to the top of the first spring. Both ends of the grinding roller are fixedly connected to the lifting block respectively.
[0007] Preferably, fixing plates are fixedly installed on both sides inside the frame. A cylinder is fixedly connected to one side of the fixing plate. The cylinder is fixedly connected to a slider. A slider is slidably connected to the fixing plate. The slider is fixedly connected to the motor.
[0008] Preferably, a lifting plate is fixedly installed at the bottom of a plurality of movable rods. The lifting plate is elastically connected to a lifting vertical plate. The lifting vertical plate is slidably connected to the guide groove. The angle between the lifting vertical plate and the guide groove is ninety degrees. A plurality of material arranging rollers are fixedly connected to the top of the lifting vertical plate. A distributor is fixedly connected to one end of the guide groove. A plurality of material passing channels are equidistantly opened on the distributor.
[0009] Preferably, the opening angle of the material passing channel towards the limit cover is greater than the opening angle of the other end of the material passing channel.
[0010] Preferably, a connecting handle is fixedly connected to the bottom of each second wedge plate. Each connecting handle extends to the bottom of one end of the guide groove through the lifting vertical plate. A rack is fixedly connected to one end of each connecting handle. Third gears are rotatably connected to both sides at the bottom of one end of the guide groove. Cleaning devices are fixedly connected to the top of the third gears. A plurality of cleaning strips are fixedly connected to the cleaning devices. Each cleaning strip corresponds to each material passing channel one by one.
[0011] Preferably, a secondary grinding area is formed by the middle of the pressing plate being recessed downward. A sleeve is sleeved on the rocker arm, and the sleeve fits with the secondary grinding area.
[0012] Preferably, a plurality of discharge plates are fixedly installed inside the sieve, a grading sieve is fixedly installed in the middle of the sieve, an electric spray head is fixedly installed at the bottom inside the sieve, a supplementary light sensor is fixedly installed at the top inside the sieve, a middle baffle is fixedly installed between the limit cover and the electric spray head, and a plurality of discharge grooves are fixedly connected to the bottom of the frame, and each discharge groove corresponds to the end of each guide groove.
[0013] Preferably, side plate edges are fixedly installed on both sides inside the guide groove.
[0014] Preferably, the usage method includes the following steps: a. First preparation: The ginseng is washed and dried, then dehydrated and dried, and finally sliced and collected. b. Primary screening: After the ginseng is picked up manually and put into each feeding groove one by one, after the ginseng is fed, it starts to fall onto the material distribution groove. The material distribution groove is used for primary screening of the ginseng, and the material distribution groove can also slow down the falling speed of the ginseng, assisting the grinding plate on the guide groove to trim the surface of the ginseng. When the ginseng starts to fall onto the guide groove, the motor is started to rotate in real time. When the motor rotates, it drives the second gear to rotate. The rotation of the second gear can drive the first gear to rotate, so that the rocker drives the pressing plate to reciprocate up and down at the bottom of the limit cover during the rotation process, so that the first wedge plate drives the second wedge plate to move towards one end of the guide groove during the descending process, and the top of the grinding roller moves down along the inclined surface at the bottom of the inclined plate, so that the first spring descends, and the grinding roller approaches the surface of the grinding plate, and polishes the two sides of the ginseng located between the grinding roller and the grinding plate to remove the dirt and impurities on its surface. c. Material sorting and screening: When the ginseng passes through the primary screening, it falls to the other end of the guide groove along the slope of the guide groove. When the ginseng starts to pass through the lifting vertical plate and the sorting roller, due to the certain intervals on the sorting roller, the ginseng with relatively smaller volume and area will have a higher passing rate than the ginseng with relatively larger volume and area. The ginseng with relatively smaller volume and area will quickly pass through the feeding channel, while the ginseng with relatively larger volume and area will gradually make the edge of the ginseng contact the end of the larger opening of the feeding channel during the lifting process of the sorting roller, and then classify the ginseng with different volumes and areas according to the passing order. d. Electric control screening: After ginseng with relatively small volume and area passes through the feeder, the supplementary light sensor and the electric nozzle inside the sieve are turned on simultaneously. The supplementary light sensor supplements light to the channel between the sieve and the guide groove to prevent double images from occurring between ginseng. Among them, the camera inside the sieve screens and identifies ginseng, and the electric nozzle blows ginseng with different volume sizes or obvious color abnormalities, classifying ginseng of different grades into each discharge chute, and then collecting the ginseng manually.
[0015] Compared with the prior art, the beneficial effects of the present invention are: When the swing arm of the present invention rotates, the surface of the swing arm contacts the pressing plate, thereby causing the pressing plate to descend on the guide groove, compressing the second spring, and causing the movable rod to descend. When the movable rod descends, the pressing plate also descends, and at the same time, the first wedge plate located at the bottom of the pressing plate descends. During the descent of the first wedge plate, it drives the second wedge plate to move towards one end of the guide groove. When the second wedge plates located in the same guide groove move, the grinding roller moves synchronously along the second wedge plate. At the same time, the top of the grinding roller contacts the bottom of the inclined plate. As the two second wedge plates descend, the swing arm drives the pressing plate to reciprocally lift and lower under the limit cover during the rotation process, so that the first wedge plate drives the second wedge plate to move towards one end of the guide groove during the descent process, causing the top of the grinding roller to move and descend along the inclined surface of the bottom of the inclined plate, causing the first spring to descend, and the grinding roller to approach the surface of the grinding plate, polishing both sides of the ginseng located between the grinding roller and the grinding plate to remove dirt and impurities on its surface, improving the cleaning degree of the upper and lower surfaces of the ginseng, thereby assisting the machine to improve the recognition rate and reducing the recognition error of the equipment.

Detailed implementation manners
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-9, the present invention provides a technical solution: an automatic screening and classification device for fine processing of ginseng and its use method, including a frame 1. A plurality of blanking devices 3 are fixedly installed at equal intervals on the top of the frame 1. The blanking device 3 is composed of each feeding groove 5 in a rectangular shape. A screening device 2 is fixedly installed on one side of the frame 1, and a separator 6 is fixedly installed on the other side of the frame 1. At the top corner on one side of the separator 6, guide grooves 4 are fixedly installed at equal intervals in a linear arrangement. A limit cover 9 is fixedly installed at the top of the middle of each guide groove 4. Both sides inside the frame 1 are connected with motors 13. A second gear 15 is sleeved on the output shaft of the motor 13. A connecting block is slidably connected to each limit cover 9. A rocker arm 16 is connected in series between each connecting block. Both ends of the rocker arm 16 are fixedly connected with a first gear 14. The first gear 14 and the second gear 15 are engaged together. The first gear 14 is close to one side of the rocker arm 16. An activity rod is connected to the middle of the guide groove 4. A second spring is sleeved on each activity rod. The common end of the plurality of activity rods is fixedly connected with a pressing plate 34. One end of the bottom of the pressing plate 34 is fixedly installed with a first wedge plate 35. Both sides inside the guide groove 4 are slidably connected with a second wedge plate 38. A grinding roller 36 is movably connected between the two second wedge plates 38. An inclined plate 23 is fixedly installed at the top of the guide groove 4. A grinding plate 25 is fixedly installed at the bottom inside the guide groove 4. First, the ginseng is sliced, and then it is manually put into each feeding groove 5. The feeding groove 5 and the guide groove 4 are communicated, so that the ginseng flows to the top of the guide groove 4. Then the motor 13 is started to rotate. When the motor 13 rotates, it drives the second gear 15 to rotate. When the second gear 15 rotates, it makes the first gear 14 rotate. When the first gear 14 rotates, it makes the rocker arm 16 rotate. When the rocker arm 16 rotates, the surface of the rocker arm 16 contacts the pressing plate 34, so that the pressing plate 34 descends on the guide groove 4, compresses the second spring, and makes the activity rod descend. When the activity rod descends, the pressing plate 34 also descends at the same time, and at the same time, the first wedge plate 35 located at the bottom of the pressing plate 34 descends. During the descent of the first wedge plate 35, it drives the second wedge plate 38 to move towards one end of the guide groove 4. When the second wedge plates 38 located inside the same guide groove 4 move, the grinding roller 36 moves synchronously along the second wedge plate 38. At the same time, the top of the grinding roller 36 contacts the bottom of the inclined plate 23. As the two second wedge plates 38 descend, the rocker arm 16 drives the pressing plate 34 to reciprocally lift and lower under the limit cover 9 during the rotation process, so that the first wedge plate 35 drives the second wedge plate 38 to move towards one end of the guide groove 4 during the descent process, and the top of the grinding roller 36 moves down along the inclined surface of the bottom of the inclined plate 23, making the first spring 39 descend, and the grinding roller 36 approaches the surface of the grinding plate 25, polishing the two side surfaces of the ginseng located between the grinding roller 36 and the grinding plate 25 to remove the dirt and impurities on its surface, improving the cleaning degree of the upper and lower surfaces of the ginseng, thereby assisting the machine to improve the recognition rate and reducing the recognition error of the equipment.
[0020] Specifically, the grinding plate 25 is located directly below the inclined plate 23. A first spring 39 is fixedly installed inside each second wedge plate 38. The top of the first spring 39 is fixedly connected to a lifting block 37. Both ends of the grinding roller 36 are fixedly connected to the lifting block 37 respectively. When the pressing plate 34 descends, the pressing plate 34 descends along the bottom inclined surface of the inclined plate 23, the first spring 39 is compressed, and the lifting block 37 slides inside the second wedge plate 38, improving the stability of both ends of the grinding roller 36 during sliding.
[0021] Furthermore, fixed plates 10 are fixedly installed on both sides inside the frame 1. One side of the fixed plate 10 is fixedly connected to a cylinder 11. The cylinder 11 is fixedly connected to a slider 12. The slider 12 is slidably connected to the fixed plate 10. The slider 12 is fixedly connected to a motor 13. If it is necessary to adjust the grinding position of the grinding roller 36 on the grinding plate 25, the cylinder 11 can be directly controlled to expand and contract in the background. The slider 12 is used to control the position of the swing arm 16 and can also control the position of the motor 13. After the grinding position of the grinding roller 36, it is beneficial to increase the grinding area of the grinding roller 36, expand the range of polishing ginseng, and improve the screening efficiency.
[0022] Furthermore, a lifting plate 27 is fixedly installed at the bottom of multiple movable rods. The lifting plate 27 is elastically connected to a lifting vertical plate 32. A telescopic tube (not shown in the drawings) can be installed between the two. The lifting vertical plate 32 is slidably connected to the guide groove 4. The angle between the lifting vertical plate 32 and the guide groove 4 is ninety degrees. The top of the lifting vertical plate 32 is fixedly connected to multiple material sorting rollers 33. One end of the guide groove 4 is fixedly connected to a material distributor 22. A plurality of material passing channels 26 are equidistantly arranged on the material distributor 22. The opening angle of the material passing channel 26 towards one end of the limit cover 9 is greater than the opening angle of the other end of the material passing channel 26; there is a certain interval between the material sorting rollers 33. Therefore, ginseng with relatively smaller volume and area has a higher passing rate than ginseng with relatively larger volume and area. Ginseng with relatively smaller volume and area is more likely to pass through the material passing channel 26 at a faster speed. While ginseng with relatively larger volume and area will gradually make the edge of the ginseng contact the larger opening end of the material passing channel 26 during the lifting and lowering process of the material sorting rollers 33, and then classify the passing order of ginseng with different volumes and areas. During the back-and-forth lifting and lowering process of the lifting vertical plate 32, the material sorting rollers 33 move on one side of the material distributor 22, thereby correcting the position of the ginseng on one side of the material distributor 22 and assisting ginseng with different volumes and areas to pass through the material passing channel 26, thus improving the accuracy of the machine for screening ginseng with different volumes and areas.
[0023] Further, a connecting handle 28 is fixedly connected to the bottom of each second wedge plate 38. Each connecting handle 28 extends to the bottom of one end of the guide groove 4 along the lifting vertical plate 32. A rack 29 is fixedly connected to one end of each connecting handle 28. Third gears 30 are rotatably connected to both sides of the bottom of one end of the guide groove 4. Cleaning devices are fixedly connected to the tops of the third gears 30. A plurality of cleaning bars 31 are fixedly connected to the cleaning devices. Each cleaning bar 31 corresponds to each material passing channel 26 one by one. When the ginseng is stuck inside the material passing channel 26, during the process of driving the second wedge plate 38 to move by the downward movement of the pressing plate 34, the rack 29 can be driven to move. When the rack 29 moves periodically, the third gear 30 can be rotated forward and backward by 180°, so that the cleaning bar 31 is rotated forward and backward by 180°, peeling off the ginseng stuck inside the material passing channel 26, and then enabling the ginseng to pass through the material distributor 22 during the screening process, thereby effectively reducing the equipment failure rate.
[0024] Further, a secondary grinding area is formed by the middle part of the pressing plate 34 sinking downward. A sleeve 1601 is sleeved on the rocker arm 16, and the sleeve 1601 fits with the secondary grinding area. When the ginseng is put in, after the ginseng contacts the guide groove 4, due to partial elasticity, part of the ginseng may cross over the grinding roller 36 and come above the pressing plate 34. Therefore, a secondary grinding area is also provided above the pressing plate 34. After the sleeve 1601 contacts the pressing plate 34 during the rotation of the rocker arm 16, the ginseng located inside the secondary grinding area can be polished, reducing the machine error rate.
[0025] Further, a plurality of discharge plates 17 are fixedly installed inside the sieve 2. A grading sieve 21 is fixedly installed in the middle of the sieve 2. An electric spray head 18 is fixedly installed at the inner bottom of the sieve 2. A supplementary light sensor 20 is fixedly installed at the inner top of the sieve 2. A middle baffle 19 is fixedly installed between the limit cover 9 and the electric spray head 18. A plurality of discharge grooves 8 are fixedly connected to the bottom of the frame 1. Each discharge groove 8 corresponds to the end of each guide groove 4. Side plate seals 24 are fixedly installed on both sides inside the guide groove 4. The supplementary light sensor 20 supplements light to the channel between the sieve 2 and the guide groove 4 to prevent ghosting between the ginseng. The camera located inside the sieve 2 screens and identifies the ginseng. The electric spray head 18 blows the ginseng with different volumes or obvious color abnormalities, and then the ginseng that has been screened can be collected manually.
[0026] The usage method includes the following steps: a. First preparation: The ginseng is washed and dried, then dehydrated and dried, and finally sliced and collected. b. Primary screening: After the ginseng is manually picked up one by one and placed into each feeding chute 5, after the ginseng is fed, it starts to fall onto the material distribution chute 7. The material distribution chute 7 is used for the primary screening of the ginseng, and the material distribution chute 7 can also slow down the falling speed of the ginseng, assisting the grinding plate 25 on the auxiliary guide chute 4 to trim the surface of the ginseng. When the ginseng starts to fall onto the guide chute 4, the motor 13 is started to rotate in real time. When the motor 13 rotates, it drives the second gear 15 to rotate. The rotation of the second gear 15 can drive the first gear 14 to rotate, so that the rocker arm 16 drives the pressing plate 34 to reciprocate up and down at the bottom of the limit cover 9 during the rotation process, so that the first wedge plate 35 drives the second wedge plate 38 to move towards one end of the guide chute 4 during the descending process, and the top of the grinding roller 36 moves down along the inclined surface of the bottom of the inclined plate 23, causing the first spring 39 to descend, and the grinding roller 36 approaches the surface of the grinding plate 25, and polishes the two side surfaces of the ginseng located between the grinding roller 36 and the grinding plate 25 to remove the dirt and impurities on its surface; c. Material sorting and screening: After the ginseng passes the primary screening, it falls to the other end of the guide chute 4 along the slope of the guide chute 4. When the ginseng starts to pass through the lifting vertical plate 32 and the sorting roller 33, since there are certain intervals on the sorting roller 33, the ginseng with relatively smaller volume and area has a higher passing rate than the ginseng with relatively larger volume and area. The ginseng with relatively smaller volume and area will quickly pass through the feeding channel 26, while the ginseng with relatively larger volume and area will gradually make the edge of the ginseng contact the larger opening end of the feeding channel 26 during the lifting and lowering process of the sorting roller 33, and then classify the ginseng with different volumes and areas according to the passing order; d. Electric control screening: When the ginseng with relatively smaller volume and area passes through the distributor 22, the supplementary light sensor 20 and the electric spray head 18 inside the sieve 2 are opened at the same time. The supplementary light sensor 20 supplements light to the channel between the sieve 2 and the guide chute 4 to prevent ghosting between the ginseng. The camera inside the sieve 2 screens and identifies the ginseng, and the electric spray head 18 blows the ginseng with different volume sizes or obvious color abnormalities, classifying the ginseng of different grades into each discharging chute 8, and then collecting the ginseng manually.

9. The automated screening and classification device for refined processing of ginseng according to claim 8, characterized in that: Side plate seals (24) are fixedly installed on both sides inside the guide groove (4).
10. The usage method required when using the automatic screening and classification device for refined processing of ginseng according to any one of claims 1-9, characterized in that: It includes the following steps: a. First preparation: The ginseng is washed and dried, then dehydrated and dried, and finally sliced and collected. b. Primary screening: After the ginseng is picked up manually, it is put into each feeding trough (5) one by one. After the ginseng is fed, it starts to fall onto the material distributing trough (7). The material distributing trough (7) is used for primary screening of the ginseng, and the material distributing trough (7) can also slow down the falling speed of the ginseng, assisting the grinding plate (25) on the guide groove (4) to trim the surface of the ginseng. When the ginseng starts to fall onto the guide groove (4), the motor (13) is started to rotate in real time. When the motor (13) rotates, it drives the second gear (15) to rotate. The rotation of the second gear (15) can drive the first gear (14) to rotate, so that the swing arm (16) drives the pressing plate (34) to reciprocate up and down at the bottom of the limit cover (9) during the rotation process, so that the first wedge plate (35) drives the second wedge plate (38) to move towards one end of the guide groove (4) during the descending process, and the top of the grinding roller (36) moves down along the inclined surface of the bottom of the inclined plate (23), causing the first spring (39) to descend, and the grinding roller (36) approaches the surface of the grinding plate (25), and the two side surfaces of the ginseng located between the grinding roller (36) and the grinding plate (25) are polished to remove the dirt and impurities on its surface. c. Material sorting and screening: After the ginseng passes the primary screening, it falls to the other end of the guide chute (4) along the slope of the guide chute (4). When the ginseng starts to pass through the lifting vertical plate (32) and the material arranging roller (33), due to the certain intervals on the material arranging roller (33), the ginseng with relatively smaller volume and area has a higher passing rate than the ginseng with larger volume and area. The ginseng with relatively smaller volume and area will quickly pass through the feeding channel (26), while the ginseng with larger volume and area will gradually make the edge of the ginseng contact with the larger opening end of the feeding channel (26) during the lifting process of the material arranging roller (33), and then classify the ginseng with different volumes and areas according to the passing order. d. Electric control screening: After the ginseng with relatively smaller volume and area passes through the distributor (22), the supplementary light sensor (20) and the electric spray head (18) inside the sieve (2) are simultaneously turned on. The supplementary light sensor (20) supplements light to the channel between the sieve (2) and the guide chute (4) to prevent ghosting between the ginseng. The camera inside the sieve (2) screens and identifies the ginseng, and the electric spray head (18) blows the ginseng with different volume sizes or obvious color abnormalities, classifying ginseng of different grades into each discharging chute (8), and then the ginseng is collected manually.
