Description

Technical Field

[0001] This utility model relates to the technical field of konjac sorting devices, and in particular to a flexible sorting device for konjac seed tubers. Background Technology

[0002] Konjac is a specialty agricultural crop with high economic value. Konjac flour, processed from its tubers, is rich in glucomannan and is widely used in food, medicine, and chemical industries. Konjac mainly reproduces asexually through its tubers (i.e., "seed tubers"). The size, weight, and health of the seed tubers directly affect the subsequent germination rate, growth vigor, and final yield. Therefore, accurately grading and sorting the seed tubers according to size, weight, and quality before planting is a key preliminary step to ensure standardized konjac cultivation and improve industry efficiency.

[0003] Currently, the sorting of konjac seed tubers mostly uses auxiliary sorting machinery and equipment, such as drum screens or vibrating screens. However, their functions are usually relatively simple, and the internal structure of these auxiliary equipment is mostly rigid. During the screening process, they are prone to friction, collision, and rolling impact with the surface of the seed tubers. Since the skin of konjac seed tubers is thin and delicate and fragile, it is very easy to cause mechanical damage. These surface damages not only reduce the commercial grade of the seed tubers, but also become a breakthrough point for bacterial infection, causing them to rot during storage or cause diseases after planting. This seriously restricts the large-scale and standardized development of the konjac industry.

[0004] Therefore, how to provide a flexible sorting device for konjac seed tubers is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a flexible sorting device for konjac seed tubers, which solves the problems mentioned in the background art.

[0006] A flexible sorting device for konjac seed tubers according to an embodiment of the present utility model includes a placement frame. A feeding hopper is fixedly connected to one side of the placement frame, and a material distribution component is rotatably connected to the inner wall of the feeding hopper near the outlet of the feeding hopper. A screening component is provided inside the placement frame at the tail end of the material distribution component, and a positioning component is provided on the side of the screening component. The side of the positioning component is fixedly connected to the inner wall of the placement frame.

[0007] The material distribution assembly includes a rotating material distribution screen plate and a separator rod assembly. The rotating material distribution screen plate is rotatably connected to the side of the inner wall of the placement frame and located below the feed hopper. The separator rod assembly is fixedly connected to the top of the rotating material distribution screen plate.

[0008] The number of the dividing rod groups is greater than two, and the number of dividing rod groups in each group is greater than two. The dividing rod groups with more than two groups are arranged alternately on the top of the rotating material distribution screen plate.

[0009] The placement frame is internally rotatably connected to a drive shaft. A cam is fixedly sleeved on the surface of the drive shaft. The surface of the cam is movably connected to the lower surface of the rotating material distribution screen plate. A drive motor is fixedly installed on the side of the placement frame. A drive gear is fixedly installed on the output shaft of the drive motor. A transmission gear is fixedly installed on one end of the drive shaft extending to the outside of the placement frame. The drive gear and the transmission gear mesh with each other.

[0010] The screening assembly includes a coarse screening plate and a fine screening plate. The coarse screening plate is mounted on a positioning component, and the upper surface of the fine screening plate is fixedly connected to the lower surface of the coarse screening plate. The fine screening plate is located directly below the coarse screening plate.

[0011] The cam component has a guide groove on its side, and the coarse screening plate has a horizontal sliding groove on its side near the guide groove. A sliding block is slidably connected inside the sliding groove, and a driving rod is fixedly connected to the side of the sliding block. The driving rod is movably connected inside the guide groove.

[0012] The positioning component includes a guide groove, a first wave strip, and a second wave strip. The side of the guide groove is fixedly connected to the side of the inner wall of the placement frame. The first wave strip is fixedly connected to the inner wall of the guide groove, and the second wave strip is fixedly connected to the side of the coarse screening plate. The surfaces of the first and second wave strips are movably connected. There are two sets of positioning components, which are symmetrically arranged about the coarse screening plate. When the crest of one set of first wave strips aligns with the trough of one set of second wave strips, the crest of the other set of first wave strips is movably connected with the trough of the other set of second wave strips.

[0013] A collection frame is movably placed at one end of the placement frame, located at the tail end of the coarse screening plate and the fine screening plate. The coarse screening plate and the fine screening plate are inclined downward at the end near the collection frame. A flexible buffer layer is provided inside the feed hopper, on the rotating material distribution screen plate, the coarse screening plate, the fine screening plate, and the surface of the separator rod assembly.

[0014] The beneficial effects of this utility model are: By employing a double-layer structure with coarse and fine screening plates, seed taro of different sizes can be graded and screened. Combined with the corrugated strip structure design in the positioning component, the screening plate generates slight vibration in the horizontal direction, enhancing the screening effect and accuracy. The rotating distributing screen plate and the staggered partition rod group in the distributing component, combined with the flexible buffer layer on the surface, effectively buffer the impact force of the material being discharged, preventing damage to the konjac seed taro due to collision or friction during the sorting process.

[0015] The material distribution component achieves periodic rotation through a drive shaft, cam components, and gear transmission, which evenly disperses the seed potatoes and gradually propels them to the screening component, avoiding accumulation and blockage, and improving sorting smoothness and efficiency. Through the cooperation of the cam component guide groove, sliding block, and drive rod, the rotational motion of the drive shaft is converted into the composite motion of the screening component. The overall structure has strong linkage, low power consumption, and stable operation.

[0016] The screening plate is tilted and equipped with a collection frame at the end for easy sorting and collection of seed taro. The positioning components adopt a symmetrical wave strip design to ensure the balance of the screening plate movement, reduce wear, and extend the service life of the equipment.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-4In this embodiment, a placement frame 1 is included. A feeding hopper 2 is fixedly connected to one side of the placement frame 1. A material distribution assembly 3 is rotatably connected to the inner wall of the feeding hopper 2 near the outlet of the feeding hopper 2. The material distribution assembly 3 includes a rotating material distribution screen plate 6 and a separating rod assembly 7. The rotating material distribution screen plate 6 is rotatably connected to the side of the inner wall of the placement frame 1 and located below the feeding hopper 2. The separating rod assembly 7 is fixedly connected to the top of the rotating material distribution screen plate 6.

[0025] In practice, the rotating material distribution screen plate 6 is tilted downwards at the end away from the feed hopper 2. The mesh size on the rotating material distribution screen plate 6 is the same as that on the coarse screening plate 13. The seed tubers screened by the rotating material distribution screen plate 6 fall onto the fine screening plate 14. The separating rod group 7 is perpendicular to the surface of the rotating material distribution screen plate 6 to block the forward movement of the konjac seed tubers and to separate them, so that the falling konjac seed tubers are dispersed. A baffle plate is fixedly installed at the top of the placement frame 1, directly above the rotating material distribution screen plate 6. The baffle plate prevents the falling seed tubers from jumping too much. A flexible buffer layer is also provided on the inner side of the baffle plate.

[0026] refer to Figure 1-4 In this embodiment, the number of the separator rod groups 7 is greater than two, and the number of separator rod groups 7 in each group is greater than two. The separator rod groups 7, which are greater than two groups, are arranged alternately on the top of the rotating material distribution screen plate 6.

[0027] In practice, this staggered arrangement of the blocking mechanism effectively separates the konjac seed tubers.

[0028] refer to Figure 1-4 In this embodiment, a drive shaft 8 is rotatably connected inside the placement frame 1. A cam 9 is fixedly sleeved on the surface of the drive shaft 8. The surface of the cam 9 is movably connected to the lower surface of the rotating material distribution screen plate 6. A drive motor 10 is fixedly installed on the side of the placement frame 1. A drive gear 11 is fixedly installed on the output shaft of the drive motor 10. A transmission gear 12 is fixedly installed on one end of the drive shaft 8 that extends to the outside of the placement frame 1. The drive gear 11 and the transmission gear 12 mesh with each other.

[0029] In specific implementation, the cam 9 here is an elliptical disk. When it rotates, it drives the rotating material distribution screen plate 6 to swing up and down around the rotation position of the inner wall of the placement frame 1, thereby achieving better separation and screening effect. The drive motor 10 is an existing geared motor. The size is adapted to the size of the placement frame 1 and the rotating shaft. It is not limited to one model. The drive motor 10 is powered by an external municipal power supply system. The drive motor 10 is equipped with a switch. When the switch is turned on, the drive motor 10 starts to rotate. When the switch is turned off, the drive motor 10 stops working.

[0030] refer to Figure 1-4In this embodiment, a screening component 4 is provided inside the placement frame 1 at the tail end of the material distribution component 3. The screening component 4 includes a coarse screening plate 13 and a fine screening plate 14. The coarse screening plate 13 is set on the positioning member 5. The upper surface of the fine screening plate 14 is fixedly connected to the lower surface of the coarse screening plate 13. The fine screening plate 14 is located directly below the coarse screening plate 13.

[0031] In practice, after the coarse screening plate 13 initially screens the konjac seed tubers, they are then screened by the fine screening plate 14, achieving the purpose of secondary sorting. This effectively separates three different sizes of konjac seed tubers. To further slow down the seed tuber speed, a flexible curtain is rotatably connected to the top of the coarse screening plate near the outlet of the rotating material distribution screen plate.

[0032] refer to Figure 1-4 In this embodiment, the cam component 9 has a guide groove 15 on its side, and the coarse screening plate 13 has a horizontal sliding groove 16 on its side near the guide groove 15. A sliding block 17 is slidably connected inside the sliding groove 16, and a driving rod 18 is fixedly connected to the side of the sliding block 17. The driving rod 18 is movably connected inside the guide groove 15.

[0033] In specific implementation, for better screening effect, the rotation of the cam 9 will drive the sliding block 17 to move through the guide groove 15 and the driving rod 18. The movement of the sliding block 17 will drive the coarse screening plate 13 to slide through the positioning part 5 through the sliding groove 16. The rotation of the cam 9 achieves the purpose of reciprocating sliding of the coarse screening plate 13. Since the fine screening plate 14 is fixed to the coarse screening plate 13, the reciprocating sliding of the coarse screening plate 13 will drive the reciprocating sliding of the fine screening plate 14. This achieves the reciprocating movement of the coarse screening plate 13 and the fine screening plate 14 to drive the konjac seed tuber to roll. This rolling makes it less likely for the konjac seed tuber to get stuck in the holes on the coarse screening plate 13 and the fine screening plate 14, and also improves the mobility of the konjac seed tuber, achieving a better sorting effect.

[0034] refer to Figure 1-4 In this embodiment, the screening component 4 is provided with a positioning member 5 on its side. The side of the positioning member 5 is fixedly connected to the inner wall of the placement frame 1. The positioning member 5 includes a guide groove 19, a first wave strip 20, and a second wave strip 21. The side of the guide groove 19 is fixedly connected to the side of the inner wall of the placement frame 1. The first wave strip 20 is fixedly connected to the inner wall of the guide groove 19. The second wave strip 21 is fixedly connected to the side of the coarse screening plate 13. The surface of the first wave strip 20 is movably connected to the surface of the second wave strip 21. There are two sets of positioning members 5. The two sets of positioning members 5 are symmetrically arranged about the coarse screening plate 13. When the crest of one set of first wave strip 20 aligns with the trough of one set of second wave strip 21, the crest of the other set of first wave strip 20 aligns with the trough of the other set of second wave strip 21.

[0035] In practice, while the coarse screening plate 13 moves back and forth, it is pushed to sway back and forth during the reciprocating motion by the compression of the first wave bar 20 and the second wave bar 21. The swaying of the coarse screening plate 13 drives the fine screening plate 14 to sway synchronously. In this way, while moving back and forth in the X-axis direction, the swaying in the Y-axis direction is increased, which further improves the sorting effect of konjac seed tubers.

[0036] refer to Figure 1-4 In this embodiment, a collection frame 22 is movably placed at one end of the placement frame 1 at the tail end of the coarse screening plate 13 and the fine screening plate 14. The coarse screening plate 13 and the fine screening plate 14 are inclined downward at the end near the collection frame 22. A flexible buffer layer is provided inside the feed hopper 2, on the rotating material distribution screen plate, the coarse screening plate 13, the fine screening plate 14 and the surface of the separator rod group 7.

[0037] In specific implementation, the number of frames in the collection frame 22 matches the number of sorting and grading layers. Here, three layers are set at the bottom of the coarse screening plate 13, the fine screening plate 14, and the placement rack 1 to collect the three different grades of seed tubers after sorting. The flexible buffer layer increases the protection of the konjac seed tubers, avoiding collisions that could damage them. To reduce surface damage to the konjac seed tubers, such as... Figure 2 As shown, the distance between the coarse screening plate 13 and the fine screening plate 14, and between the fine screening plate 14 and the bottom of the inner wall of the placement rack 1, is relatively narrow. In order to avoid the large falling inertia from affecting the konjac seed tuber, the flexible buffer layer here is an elastic rubber layer.

[0038] The working principle of this utility model is as follows: After the konjac seed tubers fall from the feed hopper 2 into the distribution assembly 3, the drive motor 10 drives the drive shaft 8 to rotate via the drive gear 11 and transmission gear 12. The cam component 9 fixed on the drive shaft 8 rotates accordingly, pushing the rotating distribution screen plate 6 to oscillate periodically. The top separating rod group 7 moves alternately to disperse and evenly distribute the seed tubers. The seed tubers then fall into the coarse screening plate 13 in the screening assembly 4. At this time, the drive shaft 8, through the guide groove 15 on the side of the cam component 9, cooperates with the sliding block 17 and the drive rod 18 to drive the coarse screening plate 13 to slide horizontally within the positioning component 5. The first wave strip 20 and the second wave strip 21 in component 5, due to the alternating interlocking of wave crests and troughs, guide the coarse screening plate 13 to produce slight swaying, thereby achieving coarse screening. Seed tubers that do not pass through the coarse screening slide along the inclined plate into the top frame of the collection frame 22, while seed tubers that pass through the coarse screening fall to the fine screening plate 14 for secondary screening. The fine screening plate 14 vibrates synchronously with the coarse screening plate 13 through a fixed connection, further improving the sorting accuracy. Finally, the graded seed tubers slide through the fine screening plate 14 and the bottom of the placement rack 1 into the corresponding frames in the collection frame 22, completing the entire flexible sorting process.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
