Description

Technical Field

[0001] This utility model relates to the field of pepper processing technology, and more specifically, to a pepper seed kernel selection platform based on negative pressure adsorption. Background Technology

[0002] In the deep processing of Sichuan peppercorns into oil, powder, and other products, it is often necessary to separate the peppercorn shells from the kernels (i.e., the seeds). Traditional manual sorting methods are inefficient, labor-intensive, and difficult to control in terms of hygiene. Furthermore, fatigue can easily lead to impurities in the sorting process. The differences between peppercorn shells and kernels in terms of size, density, surface texture, and aerodynamic properties provide a physical basis for mechanical sorting.

[0003] Existing seed shell separation devices use multi-layer sieves to separate the seed shells from the mixture, but they do not address the issue that whole peppercorns in the peppercorn seed shell and kernel mixture need to be dried and opened before separation.

[0004] A search revealed that Chinese patent CN221265130U discloses a device for separating pepper seed shells and kernels. By installing a drying component, the device can prevent peppers from opening during sun drying, or it can dry and open peppers that have not opened after sun drying, thereby improving the separation efficiency of the device.

[0005] In actual use, when the above-mentioned pepper seed shell and kernel separation device is used, the peppers tend to pile up into clumps when the traditional equipment is feeding, resulting in excessively high pepper density in some areas. During negative pressure adsorption, the piled peppers cannot be effectively adsorbed due to obstruction, resulting in missed selection or insufficient adsorption force. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pepper seed kernel selection platform based on negative pressure adsorption to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A pepper seed kernel sorting platform based on negative pressure adsorption includes a workbench and a collection box disposed on one side of the workbench. A fan is installed on the top of the collection box, and a connecting pipe is connected to the output end of the fan. One end of the connecting pipe is connected to the top of the collection box. An adsorption tube for negative pressure adsorption is connected to one side of the collection box. A feeding part and a sorting part are installed on the workbench. The unloading section includes an unloading housing fixedly connected to the top of the workbench and an unloading assembly disposed on the unloading housing; The sorting section includes an adsorption box fixedly connected to the inside of the workbench and an adsorption mechanism installed on the workbench. The feeding assembly includes a fixed housing fixedly connected to one side of the feeding shell. Multiple first partition plates for diverting flow are fixedly connected to the inner side of the feeding shell, forming a feeding channel between two of the first partition plates. Multiple second partition plates for further diverting flow are fixedly connected to the inner side of the feeding channel. Each of the first and second partition plates has a guide surface. A first rotating rod is rotatably connected to the inner side of the fixed housing. Multiple arc-shaped sweeping rods are fixedly connected to the outer side of the first rotating rod. Each sweeping rod has comb teeth at one end. A first variable frequency motor for driving the first rotating rod to rotate is installed on one side of the fixed housing. A first toothed plate for leveling is fixedly connected to one side of the fixed housing. A second toothed plate for assisting leveling is fixedly connected to one side of the fixed housing. A set of protruding teeth is fixedly connected to the bottom end of both the first and second toothed plates, and the two sets of protruding teeth are staggered.

[0008] As a further description of the above technical solution: the adsorption mechanism includes a conveyor belt installed inside the workbench for transmission, a drive roller and a driven roller are connected to the inner side of the conveyor belt, a second variable frequency motor for driving the drive roller to rotate is installed on one side of the workbench, a collection groove is fixedly connected to the bottom of the workbench by bolts, multiple adsorption through holes for adsorption are opened on the conveyor belt, the cross-section of the adsorption through holes is conical, a negative pressure cavity for adsorbing pepper shells is opened inside the adsorption box, two adsorption buckets with conical cross-sections are fixedly connected to the top of the adsorption box, a second rotating rod is rotatably connected inside the workbench, a third variable frequency motor for driving the second rotating rod is installed on one side of the workbench, multiple cleaning plates are fixedly connected to the outside of the second rotating rod, and the bottom of the cleaning plate corresponds to the inside of the adsorption through holes.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a feeding component, compared with the existing technology, the peppercorns can be diverted by multiple first and second partition plates, so that the peppercorns can be dispersed onto the conveyor belt. The first and second toothed plates work together to spread the peppercorns evenly, so that the peppercorns can be exposed on the surface of the conveyor belt more evenly. During the adsorption process, the force is more balanced, avoiding excessive local pressure caused by stacking, which helps to improve the negative pressure adsorption efficiency. 2. By setting up an adsorption mechanism, compared with the existing technology, the second rotating rod drives multiple cleaning plates to rotate, which can push out the pepper shells stuck in the adsorption through hole, ensuring that the adsorption through hole can be unobstructed, so as to maintain a high throughput during adsorption in the adsorption box, reduce the risk of blockage of the adsorption through hole, and further ensure the negative pressure adsorption efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] The embodiments disclosed in this application are as follows: Figure 1-8 The table shown is a pepper kernel selection table based on negative pressure adsorption, including a workbench 1 and a collection box 2 set on one side of the workbench 1. A fan 3 is installed on the top of the collection box 2. The output end of the fan 3 is connected to a connecting pipe 4. One end of the connecting pipe 4 is connected to the top of the collection box 2. An adsorption pipe 5 for negative pressure adsorption is connected to one side of the collection box 2. A feeding part and a sorting part are installed on the workbench 1. The unloading section includes an unloading housing 6 fixedly connected to the top of the workbench 1 and an unloading assembly disposed on the unloading housing 6; The sorting section includes an adsorption box 16 fixedly connected to the inside of the workbench 1 and an adsorption mechanism installed on the workbench 1. The feeding assembly includes a fixed housing 7 fixedly connected to one side of the feeding housing 6. Multiple first partition plates 8 for diverting flow are fixedly connected to the inner side of the feeding housing 6, forming a feeding channel between two first partition plates 8. Multiple second partition plates 9 for further diverting flow are fixedly connected to the inner side of the feeding channel. Each of the first partition plates 8 and second partition plates 9 has a guide surface. A first rotating rod 10 is rotatably connected to the inner side of the fixed housing 7. Multiple arc-shaped sweeping rods 11 are fixedly connected to the outer side of the first rotating rod 10. Each sweeping rod 11 has comb teeth at one end. A first variable frequency motor for driving the first rotating rod 10 to rotate is installed on one side of the fixed housing 7. A first toothed plate 12 for leveling is fixedly connected to one side of the fixed housing 7. A second toothed plate for assisting leveling is fixedly connected to one side of the fixed housing 7. 13. Both the first toothed plate 12 and the second toothed plate 13 have a set of protruding teeth fixedly connected to their bottom ends, and the two sets of protruding teeth are staggered. When the peppercorns are in the feeding shell 6, the feeding channel formed by multiple first partition plates 8 can initially divert the peppercorns, and multiple second partition plates 9 in the feeding channel can further divert the peppercorns, so that the peppercorns can be more evenly distributed on the conveyor belt 14. The first rotating rod 10 drives multiple sweeping rods 11 to sweep the peppercorns, which can further disperse the peppercorns and increase their fluidity. Then, by using the staggered cooperation of the protruding teeth on the first toothed plate 12 and the second toothed plate 13, the peppercorns can be more evenly exposed on the surface of the conveyor belt 14, which can limit the thickness of the spread, so that the peppercorn shells can be adsorbed in the future, avoiding excessive local pressure caused by stacking, and helping to improve the negative pressure adsorption efficiency.

[0021] Reference Figure 7 and 8As shown, the adsorption mechanism includes a conveyor belt 14 installed inside the workbench 1 for transmission. A drive roller and a driven roller are connected to the inner side of the conveyor belt 14. A second variable frequency motor for driving the drive roller is installed on one side of the workbench 1. A collection trough 21 is bolted to the bottom of the workbench 1. Multiple adsorption through holes 15 are formed on the conveyor belt 14, each with a conical cross-section. A negative pressure cavity 17 for adsorbing pepper shells is formed inside the adsorption box 16. Two conical adsorption buckets 18 are fixedly connected to the top of the adsorption box 16. A second variable frequency motor is rotatably connected inside the workbench 1. A third variable frequency motor for driving the second rotating rod 19 is installed on one side of the workbench 1. Multiple cleaning plates 20 are fixedly connected to the outside of the second rotating rod 19. The bottom end of the cleaning plate 20 corresponds to the inside of the adsorption through hole 15. The third variable frequency motor can drive the second rotating rod 19 to rotate, so that the second rotating rod 19 can drive the multiple cleaning plates 20 to rotate. By using the bottom end of the cleaning plate 20 to match the inside of the adsorption through hole 15, the cleaning plate 20 can clean the pepper shells stuck in the adsorption through hole 15, ensuring that the adsorption through hole 15 can be unobstructed, reducing the risk of blockage in the adsorption through hole 15, and further ensuring the negative pressure adsorption efficiency.

[0022] It is worth noting that the speeds of the first, second, and third variable frequency motors, as well as the suction force of the fan 3, can all be adjusted via an external controller. This is existing technology and can be set according to actual needs, so it will not be elaborated further.

[0023] Working principle of this utility model: This utility model designs a pepper seed kernel selection platform based on negative pressure adsorption, the specific structure of which is shown in the attached instruction manual. Figure 1-8As shown, in this technical solution, when it is necessary to sort the peppercorn kernels, the pre-treated peppercorns are first poured into the feeding shell 6. Multiple first partition plates 8 form a feeding channel inside the feeding shell 6, which can disperse the downward flow path of the peppercorns. Multiple second partition plates 9 further disperse the peppercorns on the inner side of the feeding channel, so that the peppercorns can fall onto the conveyor belt 14 more evenly and dispersedly. Then, the second variable frequency motor that drives the active roller to rotate is started by the external control equipment, so that the conveyor belt 14 can transmit the peppercorns. When the conveyor belt 14 carries the unseparated peppercorns... When the pepper moves to below the first rotating rod 10, the first variable frequency motor is started. The first variable frequency motor drives the first rotating rod 10 to drive multiple sweeping rods 11 to rotate in the opposite direction to the pepper's transmission direction. The multiple arc-shaped sweeping rods 11 with comb teeth sweep the pepper, which helps to disperse the pepper and increase its fluidity. With the continuous transmission of the conveyor belt 14, the pepper can pass under the first toothed plate 12 and the second toothed plate 13. The staggered convex teeth between the first toothed plate 12 and the second toothed plate 13 can spread the pepper evenly and limit the thickness of the spread, so that the pepper shells can be adsorbed in the subsequent process. Then, the blower 3 is started. The blower 3 generates suction through the connecting pipe 4, which creates a negative pressure inside the collection box 2. The collection box 2 is connected to the adsorption box 16 through the adsorption pipe 5, which also creates a negative pressure inside the adsorption box 16. This allows the adsorption box 16 to adsorb the pepper shells below the conveyor belt 14 through the two adsorption buckets 18. The pepper shells are very thin and light. When they fall near the adsorption through hole 15, the negative pressure airflow acts on the surface of the pepper shells, generating a torque that easily makes the pepper shells stand up. This torque works in conjunction with the adsorption through hole 15, which has a conical cross-section, so that the pepper shells can pass through the adsorption through hole 15 and enter the adsorption box 16 for adsorption. When performing negative pressure adsorption of pepper shells, the third variable frequency motor is started, and the third variable frequency motor drives the second rotating rod 19 to rotate multiple cleaning plates 20. The bottom of the cleaning plate 20 is adapted to the inner side of the adsorption through hole 15 so that when the cleaning plate 20 is inserted into the multiple adsorption through holes 15, the pepper shells stuck inside the adsorption through holes 15 can be pushed out and collected through the collection groove 21, so that the adsorption through holes 15 can maintain a high-efficiency adsorption effect.
