Description

Technical Field

[0001] This invention relates to the technical field of dry separation devices for seeded and seedless peppercorns, specifically to a peppercorn inertial air separation device using a turbine for speed increase and its usage method. Background Technology

[0002] Sichuan pepper, an important spice and traditional Chinese medicine, has a planting area exceeding 25 million mu (approximately 1.67 million hectares) and an annual output exceeding 600,000 tons. After harvesting, pepper farmers need to perform initial processing steps such as drying and seed removal before selling the peppers to buyers. However, the presence of seeds in the pepper not only reduces the quality and price of the pepper shells but also affects subsequent processing. Therefore, the efficient separation of seeded peppers from the pepper shells has become a key link in the industry's development.

[0003] Currently, pepper sorting equipment mainly includes pepper screening machines, gyratory screens, and drum screens. These traditional sorting devices are mostly designed based on vibration or sieving principles: pepper screening machines use high-frequency vibration to make peppers move in a parabolic motion on an inclined screen, using the difference in shape between branches and leaves and pepper fruits to achieve separation; gyratory screens simulate manual sieving actions, using three-dimensional oscillation to make peppers move in a spiral motion on the screen surface, removing impurities of different sizes; drum screens use rotating drums with screens of different aperture sizes to grade and screen peppers.

[0004] While the aforementioned equipment performs well in separating branches and leaves and grading by size, it faces significant challenges in separating seeded peppercorns from their husks. The diameter of the husks is similar to that of seeded peppercorns, and their shapes are similar when naturally piled up, making it difficult to effectively distinguish between seeded peppercorns and empty husks when sieving through a sieve. According to actual production data, traditional sieve sorting equipment has a mis-selection rate when separating seeded peppercorns from their husks, resulting in the waste of high-quality husks and increasing the cost of secondary manual sorting. Furthermore, after prolonged use, the sieves are easily clogged by peppercorn thorns and broken branches, further reducing sorting efficiency.

[0005] Therefore, there is an urgent need for a pepper inertial air separation device that utilizes turbine speed-up and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide a pepper inertial air separation device and its usage method that utilizes turbine speed increase, so as to overcome the shortcomings of the prior art in which seeded peppers and pepper shells are difficult to separate by particle size during screening.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a pepper inertial air separation device using a turbine to increase speed, comprising a stirring device, a feeding device connected below the stirring device, an air inlet device sleeved outside the feeding device, a wind turbine disposed below the air inlet device, a turbine platform disposed below the wind turbine and a pepper turbine placed on the turbine platform, a power device connected below the turbine platform, a pepper shell bin disposed around the power device and a pepper seed bin surrounding the pepper shell bin; a first pepper shell collection bin disposed below the pepper shell bin, and a pressing device disposed below the pepper seed bin and connected to a second pepper shell collection bin and a pepper seed collection bin.

[0008] Furthermore, the bottom of the pepper shell chamber and the seeded pepper chamber is provided with a bottom plate. The bottom plate is inclined in the middle and low around the edges, and through holes are opened around the bottom plate. The through holes are distributed in a circular array and the diameter of the through holes is larger than the diameter of the pepper. The pepper shell chamber is connected to a pepper shell enrichment channel via a through hole, and the pepper shell enrichment channel is connected to a pepper shell discharge pipe. The seeded pepper chamber is connected to a seeded pepper enrichment channel via a through hole, and the seeded pepper enrichment channel is connected to a seeded pepper discharge pipe. The pepper shell enrichment channel and the seeded pepper enrichment channel are annular and inclined, with the inclination range of 45° to 60°, so that the peppers flow from high to low.

[0009] Furthermore, the stirring device includes a stirring motor, a stirring shaft connected below the stirring motor, a stirring rod connected below the stirring shaft, a stirring funnel and a stirring outlet connected below the stirring rod, and a feeding device connected below the stirring outlet.

[0010] Furthermore, the feeding device and the air inlet device are connected as one unit. The feeding device includes an air-separated feeding pipe and a feeding port. The feeding port is connected to the mixing outlet. The air inlet device includes an air inlet pipe that is sleeved around the air-separated feeding pipe and the air inlet pipe are not connected. An opening is provided around the air inlet pipe to provide air to the wind turbine. An air inlet plate is connected to the outer periphery of the air inlet pipe, and an air inlet is formed between the air inlet pipe and the air inlet plate. The air inlet is a mesh air inlet. The wind turbine is located below the air inlet plate, and there is a gap between the wind turbine and the air inlet plate to form an annular air outlet.

[0011] Furthermore, the power unit includes a wind-separating motor, which is supported by a wind-separating motor support rod. A first concentric cylindrical plate and a second concentric cylindrical plate are arranged with the wind-separating motor shaft as the center. Adjusting the height of the first concentric cylindrical plate and its distance from the wind-separating motor shaft changes the proportion of pepper shells in the pepper shell chamber. The radius of the first concentric cylindrical plate is larger than the radius of the air inlet plate, and the area enclosed by the first concentric cylindrical plate and the wind-separating motor is the pepper shell chamber. The radius of the second concentric cylindrical plate is larger than the radius of the pepper shell chamber. The height of the first concentric cylindrical plate and the turbine platform can be slightly higher than the bottom surface of the turbine platform because the turbine platform has thickness. The height of the first concentric cylindrical plate can be slightly lower than the top surface of the turbine platform. The second concentric cylindrical plate is much higher than the top surface of the turbine platform. The gap area between the first and second concentric cylindrical plates is the pepper shell chamber containing seeds.

[0012] Furthermore, the wind turbine includes several first blades, each of which is curved and has an overall rectangular structure; the pepper turbine includes several second blades, each of which is curved and has an overall trapezoidal structure. The trapezoidal shape is chosen because the turbine platform is conical, allowing the peppercorns to fly out in a projectile motion. The upper surface of the pepper turbine is a closed structure, which is a disc. This closed structure prevents the wind from affecting the peppercorns and ensures that the wind blows downwards from the edge. The closed structure also has an opening that connects to the air-separated feed pipe, allowing the peppercorns to fall into the center of the pepper turbine.

[0013] Furthermore, the turbine platform is a disc-shaped structure with a lower center and higher edges, and a truncated cone is provided in the center of the turbine platform to prevent the peppercorns from piling up. There is no second blade obstructing the top of the truncated cone.

[0014] Furthermore, a vibrating screen is connected to the bottom of the pepper seed discharge pipe, and an exciter is connected to the bottom of the vibrating screen. The extrusion device is located at the front of the vibrating screen. The extrusion device includes a spring installed on the vibrating screen, a pepper seed extrusion shaft connected to the spring, and a pepper seed extrusion roller connected to the pepper seed extrusion shaft. The vibrating screen has several evenly distributed circular holes with a diameter larger than pepper seeds but smaller than pepper seeds and pepper shells. The circular holes are connected to a pepper seed collection bin, and the discharge port of the vibrating screen is connected to a second pepper shell collection bin.

[0015] Furthermore, the bottom of the base plate is connected to a device support tube, which consists of two first circular tubes and two second circular tubes, with the height of the first circular tubes being greater than the height of the second circular tubes.

[0016] Secondly, the present invention provides a method for using a pepper inertial air separation device that utilizes a turbine to increase speed. The method of using the aforementioned pepper inertial air separation device that utilizes a turbine to increase speed includes the following steps: The peppercorns are mixed by the stirring device to obtain a peppercorn mixture that can be evenly and smoothly fed into the feeding device. Under the action of gravity, the mixture falls into the turbine table through the feeding device. The rotation of the wind turbine and the pepper turbine causes the pepper mixture to undergo oblique projectile motion within the device; The pepper mixture includes pepper shells and peppercorns with seeds. The pepper shells fall into the pepper shell bin, and the peppercorns with seeds fall into the peppercorns with seeds bin. Pepper seeds enter the pepper seed chamber and are squeezed by the extrusion device to obtain pepper seeds and pepper shells. The pepper seeds and pepper shells fall into the pepper seed collection chamber and the pepper shell second collection chamber, respectively.

[0017] Specifically, the peppercorns are mixed by the stirring device to obtain a peppercorn mixture that can be evenly and smoothly fed into the feeding device, and then fall into the turbine table under the action of gravity. The principle of wind separation in the device is as follows: the rotation of the pepper turbine actively provides kinetic energy to the pepper mixture. The peppers with relatively large mass and seeds receive more energy than the pepper shells with relatively small mass, causing the pepper mixture to undergo oblique projectile motion in the device. The function of the wind turbine is to provide vertical downward wind force to the pepper mixture. Because the pepper shells have a larger opening and volume than the peppers with seeds, they have a larger area exposed to the wind and therefore receive greater force, making them easier to fall into the pepper shell chamber earlier. The pepper shells receive less kinetic energy than the peppers with seeds, so under similar wind conditions, the pepper shells fly a shorter distance than the peppers with seeds. The pepper mixture includes pepper shells and peppercorns with seeds; the mass of pepper shells is less than the mass of peppercorns with seeds, the pepper shells fall into the pepper shell bin, and the peppercorns with seeds fall into the peppercorn bin.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a pepper inertial air separation device and its method of use that utilizes turbine acceleration. The invention integrates stirring, feeding, wind-driven separation, turbine sorting, seed extrusion, and collection functions into one unit. After preliminary processing by the stirring device, the material is rapidly fed into the synergistic area of ​​the wind turbine and pepper turbine through a combination of the feeding and air intake devices. The dual-turbine structure combines wind power and mechanical power, causing the pepper material to undergo oblique projectile motion and be organically combined with the downward vertical wind force generated by the wind turbine. Compared to traditional single-screening methods, this significantly improves production efficiency. This invention abandons the passive separation method of traditional air separation that relies on the pepper's own gravity and the combined force of the forward airflow. Instead, it actively empowers the pepper by utilizing its own inertia, transforming passive separation into active separation. This achieves separation of pepper according to density and size from far to near, improving sorting accuracy. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] See Figure 1 and Figure 6 The present invention provides a pepper inertial air separation device that utilizes a turbine to increase speed, comprising a stirring device, a feeding device, an air inlet device, an extrusion device, a wind turbine 12, a pepper turbine 13, a turbine table 14, a pepper shell bin 17, a pepper seed bin 18, a first pepper shell collection bin 22, a pepper seed collection bin 26, a second pepper shell collection bin 27, a vibrating screen 23, a pepper seed extrusion shaft 33, a pepper seed extrusion roller 34, and a spring 35.

[0029] The specific connection is as follows: a feeding device is connected below the mixing device, an air inlet device is fitted outside the feeding device, a wind turbine 12 is installed below the air inlet device, a turbine platform 14 is installed below the wind turbine 12 and a pepper turbine 13 is placed on the turbine platform 14, a power device is connected below the turbine platform 14, two rings of sorting bins are arranged around the power device, the first ring of sorting bins is the pepper shell bin 17, the second ring of sorting bins is the pepper seed bin 18, and the pepper shell bin 17 is surrounded by pepper seed bins 18; a first pepper shell collection bin 22 is connected below the pepper shell bin 17, and a pressing device is installed in the pepper seed bin 18 and the pressing device is connected to a second pepper shell collection bin 27 and a pepper seed collection bin 26.

[0030] The peppercorns are mixed by a stirring device to obtain a peppercorn mixture containing both seeds and shells. This mixture is then evenly and smoothly conveyed to the turbine platform 14 via a feeding device connected below the stirring device. When the mixture reaches the working area of ​​the peppercorn turbine 13, the continuous rotation of the turbine causes the mixture to rotate continuously. During this process, the mixture is accelerated by the centrifugal force provided by the turbine 13, moving from the center of the turbine platform 14 towards its edge, and finally being thrown out of the turbine 13. At this point, the mixture undergoes a projectile motion within the device. An air intake device drives the airflow. During the oblique projectile motion of the peppercorns with seeds and peppercorn shells, the turbine 12 provides wind power to the area around the feeding device. The wind power acts vertically downward on the surface of the peppercorn mixture undergoing oblique projectile motion. Since the mass of the peppercorns with seeds is greater than that of the peppercorn shells, the centrifugal force and inertia of the peppercorns with seeds are greater than those of the peppercorn shells. The initial velocity of the peppercorns with seeds is also greater than that of the peppercorn shells. When the peppercorn mixture is subjected to the same vertically downward wind force, the forces on each material in the peppercorn mixture are not the same. The opening of the peppercorn shells is larger than that of the peppercorns with seeds, and their volume is also relatively larger than that of the peppercorns with seeds. Therefore, the area affected by the wind is larger, and the material with greater force is more likely to fall into the peppercorn shell hopper 17 earlier. Meanwhile, the relatively small pepper shells are more affected by the wind, and are more likely to deviate from their original oblique trajectory and fall downwards into the pepper shell bin 17, and then into the first pepper shell collection bin 22, compared to pepper shells. Pepper shells are less affected by the wind and can travel a greater distance than pepper shells to reach the pepper shell bin 18. After being squeezed by the squeezing device, the pepper shells are squeezed into pepper shells and pepper seeds. The pepper shells fall into the pepper seed collection bin 26 and the second pepper shell collection bin 27.

[0031] In some preferred embodiments of the present invention, the bottom of the pepper shell chamber 17 and the pepper seed chamber 18 is provided with a bottom plate 19. The bottom plate 19 is inclined in the middle and low around the perimeter, and through holes are opened around the perimeter of the bottom plate. The through holes are distributed in a circular array and the diameter of the through holes is larger than the diameter of the pepper. See Figure 6 The pepper shell chamber 17 is connected to the pepper shell enrichment channel 31 through a through hole. The pepper shell enrichment channel 31 is connected to the pepper shell discharge pipe 20. The seeded pepper chamber 18 is connected to the seeded pepper enrichment channel 32 through a through hole. The seeded pepper enrichment channel 32 is connected to the seeded pepper discharge pipe 21. The pepper shell enrichment channel 31 and the seeded pepper enrichment channel 32 are circular and inclined. The inclination of the pepper shell enrichment channel 31 and the seeded pepper enrichment channel 32 ranges from 45° to 60°. This allows the peppers to move from a high position to a low position. The lowest points are the pepper shell discharge pipe 20 and the seeded pepper discharge pipe 21, respectively. Finally, the peppers flow out of the device through the pepper shell discharge pipe 20 and the seeded pepper discharge pipe 21, and the diameter of the discharge pipe is much larger than the diameter of the pepper.

[0032] Therefore, the pepper shells that fall into the pepper shell chamber 17 will slide down the inclined bottom plate 19 to the corresponding through hole, and then fall into the first pepper shell collection chamber 22 through the pepper shell discharge pipe 20 via the pepper shell enrichment channel 31; the pepper seeds that fall into the pepper seed chamber 18 will slide down the inclined bottom plate 19 to the corresponding through hole, and then fall into the pepper seed discharge pipe 21 via the pepper seed enrichment channel 32, and after being squeezed by the extrusion device, they will be divided into pepper shells and pepper seeds, which will fall into the second pepper shell collection chamber 27 and the pepper seed collection chamber 26.

[0033] The bottom of the base plate 19 is connected to a device support tube 28. Since the pepper seed enrichment channel 32 is inclined, in order to ensure that the device can be placed horizontally, the device support tube 28 consists of two first round tubes and two second round tubes. The height of the first round tube is greater than the height of the second round tube. A support column is connected to the first pepper shell collection chamber 22. Its bottom height is flush with the device support tube 28 under the base plate 19 to ensure that the device is in a horizontal state.

[0034] In some preferred embodiments of the present invention, in order to convert peppercorns with seeds into peppercorn shells and peppercorn seeds into the second peppercorn shell collection chamber 27, and peppercorn seeds into the peppercorn seed collection chamber 26, the present invention provides the following technical solutions: The bottom of the peppercorn discharge pipe 21 is connected to a vibrating screen 23. An extrusion device is located at the front of the vibrating screen 23 to prevent excessive extrusion from breaking the peppercorns. The extrusion device includes a spring 35 mounted on the vibrating screen 23, a peppercorn extrusion shaft 33 connected to the spring 35, and a peppercorn extrusion roller 34 connected to the peppercorn extrusion shaft 33. Two vibrators 24, the peppercorn extrusion shaft 33, the peppercorn extrusion roller 34, and the spring 35 are connected to the bottom of the vibrating screen 23. The vibrating screen 23 has several evenly distributed circular holes 25 with a diameter larger than peppercorn seeds but smaller than both peppercorns and peppercorn shells. These holes 25 are connected to a peppercorn seed collection bin 26, and the discharge port of the vibrating screen 23 is connected to a second peppercorn shell collection bin 27. Seeded peppercorns fall through the seeded peppercorn discharge pipe 21 into the vibrating screen 23 below. Under the action of the vibrating screen 23, the spring 35 vibrates, which in turn drives the seeded peppercorn extrusion shaft 33 and the seeded peppercorn extrusion roller 34. The seeded peppercorn extrusion roller 34 can rotate on the seeded peppercorn extrusion shaft 33. As the peppercorns move along the vibrating screen 23, this reduces friction and prevents clogging. The seeded peppercorn extrusion roller 34 has a certain distance from the vibrating screen 23 and can rotate under the action of the spring 35. The adjustment mechanism can compress the peppercorns with seeds, causing them to crack open and release the seeds without clogging the vibrating screen 23. The peppercorns with seeds are compressed onto the vibrating screen 23, causing the seeds to be squeezed out and turn into peppercorn shells. The peppercorn seeds can fall through the round holes 25 on the vibrating screen 23 into the peppercorn seed collection bin 26 below. The vibrating screen 23 is placed at an angle, with the lowest end being the discharge port. The peppercorn shells can fall from here into the second peppercorn shell collection bin 27. The vibrator 24 connected to the bottom of the vibrating screen 23 provides power to the vibrating screen 23.

[0035] In some preferred embodiments of the present invention, the stirring device includes a stirring motor 2, a stirring shaft 3, a stirring rod 4, a stirring funnel 5, and a stirring outlet 6. A feeding device is connected below the stirring outlet 6. The feeding device and the air inlet device are integrated. The feeding device includes an air-selective feeding pipe 7 and a feeding port 1. The feeding port 1 is connected to the stirring outlet 6. The stirring shaft 3 is connected below the stirring motor 2. The stirring rod 4 is connected below the stirring shaft 3. The stirring funnel 5 and the stirring outlet 6 are connected below the stirring rod 4. The feeding device is connected below the stirring outlet 6.

[0036] Preferably, the feed inlet 1 is circular, and a stirring motor 2 is installed above the feed inlet 1. The stirring motor 2 drives the stirring shaft 3 to rotate, which in turn drives the stirring rod 4 above the stirring funnel 5 to loosen and mix the peppercorns. This allows the peppercorns to pass evenly and smoothly through the stirring outlet 6 into the air-separated feed pipe 7 below, preventing the peppercorns from clogging the feed due to their uneven outer shell edges and rough surfaces. The air-separated feed pipe 7 is vertically arranged and has an opening at the bottom, through which the peppercorns can fall directly onto the turbine table 14.

[0037] The air intake device includes an air intake pipe 8 that is sleeved around the air classifier feed pipe 7. The air classifier feed pipe 7 and the air intake pipe 8 are not connected and do not affect each other when air intake and material intake are performed. An opening is provided around the air intake pipe 8 to provide air to the wind turbine 12. An air intake plate 10 is connected to the outside of the air intake pipe 8, and an air inlet 9 is formed between the air intake pipe 8 and the air intake plate 10. The air inlet 9 is a mesh air inlet. The wind turbine 12 is located below the air intake plate 10, and there is a gap between the wind turbine 12 and the air intake plate 10 to form an annular air outlet. Air enters through the mesh inlet and reaches the inlet pipe 8. The air can supply air to the wind turbine 12 through the openings around the inlet pipe 8. When the wind turbine 12 rotates, it will gradually accelerate this part of the air and convert it into wind, forming a ring-shaped wind field in the horizontal direction and exiting the wind turbine 12. After the wind comes into contact with the air inlet plate 10, it will flow vertically downward from the ring-shaped air outlet. The flow rate and flow of the outflowing air are evenly distributed along the ring-shaped air outlet. At the same time, the proportion of pepper shells separated can be increased by adjusting the rotation speed of the wind turbine 12.

[0038] The feeding device and the air intake device are connected as a single unit, located above the wind turbine 12 with a certain gap. This unit and the air intake plate are supported by four air intake plate support rods 11.

[0039] In some preferred embodiments of the present invention, the wind turbine 12 includes a plurality of first blades, the first blades having an arc and being rectangular in shape; the air of the wind turbine 12 originates from the air flowing in through the openings around the air inlet pipe 8, and when the wind turbine 12 rotates, it accelerates this part of the air to generate a certain wind speed, the wind force acting horizontally on the air inlet plate 10, and then acting vertically downward along the air inlet plate 10 on the pepper mixture thrown out by the pepper turbine 13 below.

[0040] The upper surface of the pepper turbine 13 is a closed structure with a reserved opening. The pepper turbine 13 includes several second blades, which are curved and have an overall trapezoidal structure. The trapezoidal shape is chosen because the turbine platform is conical, allowing the peppers to fly out in a projectile motion. The upper surface of the pepper turbine is a closed structure, which is a disc to prevent the wind from the wind turbine from affecting the peppers and ensure that the wind blows downwards from the edge. The closed structure has a reserved opening, which is connected to the air-separated feed pipe 7 so that the peppers can fall into the center of the pepper turbine. In this embodiment... In the example, both the first and second blades are 10 in number; the pepper turbine 13 is placed on the turbine platform 14, which consists of a circular plate and 4 support rods. The turbine platform 14 is a disc-shaped structure with a low center and high edges, which facilitates the pepper being thrown out at a high height. The turbine platform 14 also has a truncated cone at its center to prevent the pepper mixture from piling up when it falls into the turbine. The edge of the second blade is close to the truncated cone, and there are no blades above the truncated cone to block it. The pepper mixture falling freely from the air separation feed pipe 7 can directly fall onto the surface of the truncated cone.

[0041] In some preferred embodiments of the present invention, the power units for the wind turbine 12 and the pepper turbine 13 are further defined; the power unit includes a wind-separating motor 15, which is supported by four wind-separating motor support rods 16. A first concentric cylindrical plate 29 and a second concentric cylindrical plate 30 are arranged with the axis of the wind-separating motor 15 as the center. Adjusting the height of the first concentric cylindrical plate 29 and its distance from the axis of the wind-separating motor 15 changes the proportion of pepper shells in the pepper shell chamber. The height of the first concentric cylindrical plate 29 can be slightly higher than the bottom surface of the turbine platform 14 because the turbine platform 14 has thickness. The height of the first concentric cylindrical plate 29 can be slightly lower than the top surface of the turbine platform 14. The second concentric cylindrical plate 30 is much higher than the top surface of the turbine platform 14. The radius of the first concentric cylindrical plate 29 is greater than the radius of the air inlet plate 10. The area enclosed by the first concentric cylindrical plate 29 and the air separator motor 15 is the pepper shell bin 17. The radius of the second concentric cylindrical plate 30 is greater than the radius of the pepper shell bin 17. The gap area between the first concentric cylindrical plate 29 and the second concentric cylindrical plate 30 is the pepper shell bin 18.

[0042] This invention also provides a method for using a pepper inertial air separation device that utilizes a turbine to increase speed. The method of using the aforementioned pepper inertial air separation device that utilizes a turbine to increase speed includes the following steps: After being mixed by the stirring device, the peppercorns form a mixture containing peppercorn seeds and peppercorn shells. The mixture is then allowed to fall evenly and smoothly under gravity into the feeding device below and into the turbine table 14.

[0043] The rotation of the wind turbine 12 and the pepper turbine 13 causes the peppercorns to undergo oblique projectile motion within the device; The mass of the peppercorn shells is less than that of the seeded peppercorns. The peppercorn shells fall into the peppercorn shell bin 17, while the seeded peppercorns fall into the seeded peppercorn bin 18. During flight, the peppercorn mixture, thrown at an angle, exhibits different inertia due to its mass difference. The peppercorn shells, being the lightest, have the least inertia and kinetic energy under the same airflow. Being slightly larger, they are more affected by the wind, thus traveling the shortest distance and falling first into the first-ring peppercorn shell bin 17. They then slide through the enrichment channel into the lower first peppercorn shell collection bin 22. The seeded peppercorns, being heavier, have stronger inertia and a relatively smaller opening and volume. Under the same airflow, they are less affected by the airflow and travel a longer distance, passing over the peppercorn shell bin 17 and falling into the second-ring seeded peppercorn bin 18. The mixture falling into the peppercorn-containing bin 18 is vibrated by the vibrating screen 23, which in turn drives the spring 35 to vibrate, thereby driving the peppercorn-containing extrusion shaft 33 and the peppercorn-containing extrusion roller 34. The peppercorn-containing extrusion roller 34 can rotate on the peppercorn-containing extrusion shaft 33. As the peppercorns move along the vibrating screen 23, this reduces friction and prevents clogging. The peppercorn-containing extrusion roller 34 has a certain distance from the vibrating screen 23 and can be adjusted by the spring 35. This allows the peppercorns to be extruded and cracked to release the seeds without clogging the vibrating screen 23. Sichuan peppercorns are processed by squeezing out the seeds, which then become peppercorn shells. These shells are then further separated by a vibrating screen 23 and a sorting structure with evenly distributed holes 25 on the screen, each with a diameter larger than the peppercorn seeds but smaller than the peppercorns and shells. During the squeezing process, the vibrating screen 23 uses high-frequency vibration to make the peppercorns, seeds, and shells move in a parabolic motion on the screen. Due to the difference in the screen aperture, the peppercorn shells and seeds eventually fall into the corresponding second collection bin 27 for peppercorn shells and the second collection bin 26 for peppercorn seeds, respectively, thus completing the entire Sichuan peppercorn sorting process.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
