Description

Technical Field

[0001] This utility model relates to the technical field of pepper processing equipment, and in particular to a device for separating pepper shells and seeds. Background Technology

[0002] Sichuan pepper originated in China, native to the Himalayas. It is a deciduous small tree or perennial plant belonging to the Rutaceae family and the Zanthoxylum genus. As is well known, Sichuan pepper consists of seeds and husks. The seeds and husks have different uses and effects, so farmers usually separate the seeds and husks for sale. However, since the seeds are contained within the pepper pericarp, a separation device is needed to separate the husks and seeds after drying.

[0003] A search revealed that Chinese Patent Publication No. CN221265130U discloses a pepper seed shell and kernel separation device. This device includes a grinding wheel assembly. When using this device, peppers fall downwards onto the top of a rotating grinding wheel. A second motor drives a second rotating shaft and the rotating grinding wheel to rotate. During the rotation of the grinding wheel, the peppers are crushed and shelled in the gap between the two sets of rotating grinding wheels. Peppers that have already opened are crushed by the rotating grinding wheel, accelerating the shelling process. Peppers that are not yet open or are about to open are crushed by the rotating grinding wheel, allowing the pepper seed shell and kernel to separate. The hemispherical soft pad effectively prevents the peppers from breaking due to excessive pressure during the crushing process, improving the convenience of the pepper seed shell and kernel separation device.

[0004] However, in actual use, after the peppercorn raw material is crushed and dehulled, the shells and seeds fall directly onto the filter screen located below the crushing structure for filtration. During this process, the larger shells accumulate on the filter screen. As the amount of shells accumulates, the seeds falling onto the filter screen will be blocked by the accumulated shells and cannot pass through the filter screen. Even if a vibration device is used to vibrate the material on the filter screen, the seeds will still take a long time to break through the shell layer, which reduces the separation efficiency. Therefore, a peppercorn shell and seed separation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for separating pepper shells and seeds, aiming to solve the problem in the prior art that as the amount of material to be separated increases, when the material reaches the filter screen, the shells that are filtered down will obstruct the seeds from passing through the filter screen, thus reducing the separation efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for separating pepper shells and seeds, comprising a separation shell, a crusher disposed inside the separation shell, a collection box disposed at the lower part of the separation shell, a drive motor fixedly connected to the front surface of the separation shell, the rear output end of the drive motor penetrating the separation shell, a rotating shaft fixedly connected to the rear output end of the drive motor, a push plate fixedly connected to the outer side of the rotating shaft, an arc-shaped filter screen disposed below the rotating shaft, baffles fixedly connected to both the front and rear surfaces of the arc-shaped filter screen, inclined plates fixedly connected to the left and right ends of the arc-shaped filter screen, a support frame disposed below the inclined plates, a limiting plate fixedly connected to the back of the arc-shaped filter screen, and a handle fixedly connected to the back of the limiting plate.

[0007] As a further description of the above technical solution:

[0008] The front surface of the arc-shaped filter screen is in contact with the front inner wall of the separation housing, and both the arc-shaped filter screen and the baffle located behind it penetrate the separation housing.

[0013] As a further description of the above technical solution:

[0014] The front of the limiting plate fits into the back of the separation shell, and the upper surface of the baffle has a chamfer on the side near the center of the arc-shaped filter screen.

[0015] As a further description of the above technical solution:

[0016] The pusher plate is located inside the arc-shaped filter screen, and the size of the pusher plate is adapted to the internal size of the arc-shaped filter screen.

[0017] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-2 This utility model provides an embodiment of a device for separating pepper shells and seeds, comprising a separation shell 1, inside which a crusher 2 is installed. The crusher 2 includes a crushing motor, a connecting shaft, a crushing roller, and a hemispherical soft pad. The crushing motor is fixedly connected to the front of the separation shell 1, and the rear output end of the crushing motor passes through the separation shell 1 and is fixedly connected to the connecting shaft. The crushing roller is fixedly connected to the outside of the connecting shaft, and the hemispherical soft pad is fixedly connected to the outside of the crushing roller. The above structure is arranged in a linear array of three sets inside the separation shell 1. When the pepper material enters the separation shell 1, it falls to the crusher 2, at which time the crushing motor starts and drives the crusher. The crushing rollers and hemispherical soft pads rotate, and the pepper material is crushed and dehulled in the gap between the two sets of crushing rollers. This is an existing technology in the field and will not be described in detail here. A collection box 3 is set at the bottom of the interior of the separating shell 1. The collection box 3 is connected to the separating shell 1 by M4×15mm cross-slot bolts. The shell opening diameter is 4.2mm. It is used with gaskets to enhance the sealing performance and prevent the seeds from leaking out. The collection box 3 can collect the material that reaches the bottom of the separating shell 1. The front end of the collection box 3 penetrates through the separating shell 1. At the same time, the front end of the collection box 3 is detachably connected to the separating shell 1 by bolts to ensure the stability of the collection box 3 during use.

[0033] Reference Figures 2-4A drive motor 4 is fixedly connected to the front surface of the separation housing 1. The rear output end of the drive motor 4 passes through the separation housing 1, and a rubber sealing sleeve is installed at the penetration point. The inner diameter of the sealing sleeve is adapted to the motor output shaft, and the outer diameter is interference-fitted with the opening of the separation housing to prevent material debris and dust from entering the motor connection part, thereby improving the sealing performance and service life of the equipment. A rotating shaft 5 is fixedly connected to the rear output end of the drive motor 4. A push plate 6 is fixedly connected to the outer side of the rotating shaft 5. When the drive motor 4 starts, it can drive the push plate 6 to rotate through the rotating shaft 5. There are two push plates 6, which are fixedly connected in a mirror structure on the outer side of the rotating shaft 5. An arc-shaped filter screen 7 is set below the rotating shaft 5. The mesh diameter of the arc-shaped filter screen 7 is set to 3-5mm to accommodate pepper seeds (usually 2-4mm in diameter) to ensure efficient separation of shells and seeds. The filter screen thickness is 2-3mm to ensure structural strength. The push plate 6 is located at... Inside the arc-shaped filter screen 7, the size of the push plate 6 is adapted to the internal size of the arc-shaped filter screen 7. The front surface of the arc-shaped filter screen 7 is in contact with the front inner wall of the separation shell 1. When the material is crushed by the crusher 2, it will fall into the arc-shaped filter screen 7. When the drive motor 4 starts and drives the rotating shaft 5 and the push plate 6 to rotate, the push plate 6 can push the material falling into the arc-shaped filter screen 7, thereby lifting the material. At the same time, the drive motor 4 is a 100-200W speed-regulating motor with a speed of 50-150r / min. When the push plate 6 rotates, the gap between it and the inner wall of the arc-shaped filter screen 7 is maintained at 1-2mm. When it rotates to a horizontal state, the bottom surface is 5-8mm away from the upper surface of the baffle 8, which avoids collision and can effectively push the material, ensuring the material's 'lifting-falling' frequency (two lifting and falling times per rotation), breaking up the accumulated shell layer and accelerating the filtration of the seed material.

[0034] Both the front and rear surfaces of the arc-shaped filter screen 7 are fixedly connected to baffles 8. The baffles 8 can block and limit the front and rear sides of the arc-shaped filter screen 7, so that the material can be stored in the arc-shaped filter screen 7. When the push plate 6 is rotated to the horizontal state, its bottom surface is higher than the upper surface of the baffle 8. At this time, the push plate 6 will not obstruct the movement of the baffle 8. The upper surface of the baffle 8 is provided with a chamfer 13 on one side near the center of the arc-shaped filter screen 7. When the material falls onto the upper surface of the baffle 8, it can slide down the inclined surface of the chamfer 13 into the arc-shaped filter screen 7, avoiding accumulation above the baffle 8 and affecting the separation effect. The arc-shaped filter screen 7 and the baffle 8 located behind it both penetrate the separation shell 1. The arc-shaped filter screen 7 can be pulled out from the rear side of the separation shell 1.

[0035] An inclined plate 9 is fixedly connected to both ends of the arc-shaped filter screen 7. The side of the inclined plate 9 away from the arc-shaped filter screen 7 is inclined upwards. The outer wall of the inclined plate 9 is in contact with the inner wall of the separation shell 1. When the material falls beyond the arc-shaped filter screen 7, it will be completely blocked by the inclined plate 9, allowing the material to slide down the inclined surface of the inclined plate 9 into the arc-shaped filter screen 7. A support frame 10 is provided below the inclined plate 9. The support frame 10 is fixedly connected to the inner wall of the separation shell 1. The upper surface of the support frame 10 is in contact with the bottom surface of the inclined plate 9. The support frame 10 can limit and support the bottom of the inclined plate 9, thereby allowing the arc-shaped filter screen 7 to be stably placed inside the separation shell 1. A limiting plate 11 is fixedly connected to the back of the housing 1. The front of the limiting plate 11 fits against the back of the housing 1. The limiting plate 11 is detachably connected to the housing 1 by bolts. The limiting plate 11 and the housing 1 are connected by M5×20mm hexagonal bolts. The housing 1 has a threaded hole with a diameter of 5.2mm and a depth of 10mm to ensure connection strength and ease of disassembly. A handle 12 is fixedly connected to the back of the limiting plate 11. When the bolts are unscrewed, the operator can quickly pull the arc-shaped filter screen 7 and the baffle 8 out of the housing 1 through the handle 12, and then quickly remove the pepper shells that have been filtered out inside the arc-shaped filter screen 7.

[0036] Reference Figure 3 and Figure 5 A feed hopper 14 is fixedly connected to the upper surface of the separation shell 1. The feed hopper 14 allows the material to flow from the center into the interior of the separation shell 1. A sealing cover 15 is provided above the feed hopper 14 to shield and protect the upper end of the feed hopper 14, preventing dust and impurities from falling into the separation shell 1 during the separation process. A triangular guide strip 16 is provided on the upper side of the interior of the separation shell 1. Inclined guide plates 17 are fixedly connected to the left and right sides above the triangular guide strip 16, respectively. The front and rear ends of the inclined guide plates 17 are fixedly connected to the inner wall of the separation shell 1. When the material enters the interior of the separation shell 1 through the feed hopper 14, the left and right sides... The material can flow along the inclined guide plate 17 to the gap between the side roller 2 and the inner wall of the separation shell 1, while the material falling from the center can flow along the inclined surfaces on both sides of the triangular guide bar 16 to the gap between the roller 2, thus allowing the material to pass through the roller 2 quickly for crushing, accelerating the separation efficiency. This equipment is suitable for dried peppercorns with a moisture content ≤15%, and wet peppercorns that have been preliminarily dried (moisture content 20%~25%). It is compatible with common peppercorn varieties (Dahongpao, Hanyuan peppercorns, green peppercorns, etc.). By adjusting the roller parameters (speed, roller gap) and the aperture of the arc-shaped filter screen 7, the shell and seed separation requirements of different varieties can be met.

[0037] Working principle: The pepper material is fed into the feed hopper 14. The sealing cover 15 can shield and protect the material when not feeding. The material entering the separation shell 1 is guided by the inclined guide plate 17 and the triangular guide strip 16 and evenly distributed to the area where the crusher 2 is located. The material enters the gap between the three sets of crushers 2. The crushing motor drives the crushing roller + hemispherical soft pad to rotate, which flexibly squeezes the pepper and realizes the separation of shell and seed (shell breaks and seed comes out). After shelling, the material falls directly or along the inclined surface of the inclined plate 9 into the arc-shaped filter screen 7. Then the drive motor 4 starts and drives the push plate 6 to rotate through the rotating shaft 5. During the rotation, the push plate 6 pushes the material to move in the filter screen, so that the material repeatedly rises and falls. This can disperse the material in the arc-shaped filter screen 7, avoid the pepper shells from piling up and affecting the subsequent fall of pepper seeds, and accelerate the filtration and separation efficiency of the material. Small particles such as pepper seeds can fall into the collection box 3 through the filter holes of the arc-shaped filter screen 7, while the pepper shells remain in the filter screen.

[0038] After separating the shells and seeds of the material, the pepper shells can be removed by pulling out the arc-shaped filter screen 7 through the handle 12 after unscrewing the bolts. Similarly, the collection box 3 can be quickly disassembled after unscrewing the bolts on the outside of the collection box 3, making it convenient to take out and clean the pepper seeds.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
