Description

Technical Field

[0001] This utility model relates to the technical field of pepper processing equipment. More specifically, this utility model relates to a pepper and pepper leaf screening device. Background Technology

[0002] After harvesting Sichuan peppercorns, the branches, leaves, stems, black seeds, and husks need to be separated and placed separately. There are three main methods of sieving: the first is manual sieving, which is inefficient and yields unsatisfactory results; the second is mechanical color sorting, which has better sieving results, but its biggest problems are the large size, high cost, complex operation, and high maintenance costs of the equipment, making it only suitable for further fine-tuning after initial screening; the third method uses mechanical vibration sieving, which has low machine costs, is easy to operate, can meet the needs of large-scale production, and aligns with the development trend of Sichuan peppercorn sieving technology and equipment.

[0003] In addition, Sichuan pepper leaves, a byproduct of Sichuan pepper, also have edible and medicinal value. Their chemical composition is complex, containing various beneficial active substances, and they possess health benefits such as antioxidant, anti-tumor, and antibacterial properties. Sichuan pepper leaves are traditionally used to kill insects, treat athlete's foot, and treat lacquer sores. They are also effective in treating cold accumulation, cholera-like muscle spasms, athlete's foot, lacquer sores, and scabies.

[0004] Most existing patents only separate the pepper shells and seeds, lacking the screening and separation of pepper leaves, a byproduct of pepper production. This leads to insufficient utilization of pepper leaves. For example, application number CN202023209001.7 describes a novel pepper screening machine with integrated crushing and air separation functions. This machine sequentially screens pepper branches, residual leaves, and small stems. However, the device's drawback is that the air separation device can only separate pepper leaves and branch fragments from the pepper together and collect them in a pepper leaf and branch fragment collection box. It does not further separate the pepper leaves from the branches, thus hindering the full utilization of pepper leaves. Utility Model Content

[0031] The present invention will now be described in detail with reference to the accompanying drawings:

[0032] Figure 1 - Figure 4 This invention discloses a screening device for Sichuan peppercorns and leaves, comprising, from top to bottom: a feed hopper 1, a crushing unit 2, an air separation unit 3, and a Sichuan peppercorn vibrating screening unit 4, wherein the crushing unit 2 and the Sichuan peppercorn vibrating screening unit 4 are connected via a feed pipe 5, and further comprising:

[0033] The air separation unit 3 includes: a fan 31, an air separation inlet pipe 32 and an air separation outlet pipe 33. One side wall of the feed pipe 5 is connected to the air separation inlet pipe 32, and the other side wall of the feed pipe 5 is connected to the air separation outlet pipe 33. The outlet end of the air separation unit outlet pipe 33 is provided with an inverted arc-shaped baffle 331, and a pepper leaf screening unit 6 is provided below the outlet end.

[0034] The pepper leaf screening unit 6 includes: a pepper leaf vibrating screening screen 61 arranged at an incline;

[0035] Branch collection box 62 is set directly below the vibrating screen 61 for pepper leaves, and its horizontal length is adapted to the horizontal length of the vibrating screen 61 for pepper leaves.

[0036] The lowest outlet of the vibrating screening mesh 61 for pepper leaves is placed on the pepper leaf collection box 63.

[0037] Working principle:

[0038] The operator puts the pepper branches with peppercorns into the feed hopper 1. The branches are crushed by the crushing unit 2, which separates the peppercorns from the leaves. The peppercorns are crushed and the peppercorn seeds are separated from the peppercorns as much as possible. The mixture after crushing is fed through the feed pipe 5 and screened by the air separation unit 3 before entering the pepper vibrating screen unit 4 below.

[0039] One side wall of the feed pipe 5 is connected to the air classifier inlet pipe 32, and the opposite side wall is connected to the air classifier outlet pipe 33. The other side of the inlet pipe 32 is connected to the air outlet of the blower 31. Driven by the wind, the pepper leaves and small branches in the feed pipe 5 are blown out of the air classifier outlet pipe 33. Under the interception of the inverted arc plate 331 at the outlet end of the air classifier outlet pipe 33 and the action of gravity, the pepper leaves and small branches fall quickly onto the pepper leaf vibrating screen 61 below.

[0040] The higher end of the vibrating screen 61 for pepper leaves is located below the air separation discharge pipe 33, and the lower end of the vibrating screen 61 for pepper leaves is provided with a pepper leaf collection box 63. Lighter materials such as pepper leaves falling from the air separation discharge pipe 33 move towards the lower end of the vibrating screen 61 for pepper leaves due to the inclined setting of the vibrating screen 61 for pepper leaves.

[0041] During the movement, the small branches are sifted out by the vibrating screening net 61 for pepper leaves, pass through the mesh and fall into the branch collection box 62 below. The larger pepper leaves are retained on the net surface and move to the lower end of the vibrating screening net 61 to fall into the pepper leaf collection box 63, thus obtaining pepper leaves without impurities.

[0042] Among them, ① in practical applications, the wind force in the air inlet pipe 32 is set to only drive the pepper leaves and extremely small branches to be picked out by the wind, so as to facilitate further screening of the pepper leaves; the pepper leaf screening unit 6 is set to directly screen and separate the pepper leaves and small branches picked out by the wind, which is convenient for the use of pepper leaves, saves the labor and time costs of screening pepper leaves again, and has high screening efficiency.

[0043] ② The pepper mixture (i.e., other substances except pepper leaves and small branches) after being screened by air separation in the feed pipe 5 continues to fall into the pepper vibrating screening unit 4 below (this structure is existing technology, and will not be elaborated on in detail here, only the working method is briefly introduced). The mesh size of the multi-stage vibrating screening screen decreases from top to bottom. The branches, small stems and small impurities in the pepper mixture are screened out step by step by the multi-stage vibrating screening screen, and then the pepper shells and pepper seeds are screened out separately, thus obtaining the required pepper shells and pepper seeds.

[0044] In the above scheme, the mesh of the pepper leaf vibrating screening mesh 61 is a square mesh, and the mesh size is configured to be smaller than the minimum particle size crushed by the crushing unit 2.

[0045] Working principle:

[0046] In practical applications, the mesh of the vibrating screening mesh 61 for pepper leaves is set to be square, and the mesh size is configured to be smaller than the minimum particle size of the crushing unit 2, so that most of the pepper leaves and their fragments cannot pass through the mesh and the small branches that are wind-selected can be screened out and fall into the branch collection box 62 below, thereby achieving the separation of pepper leaves and small branches.

[0047] As described above, a vibration mechanism 64 is provided below the vibrating screen for pepper leaves on the side near the discharge end.

[0048] The vibration mechanism 64 includes: a motor, the power output end of which is connected to an eccentric wheel 641;

[0049] The connecting rod 642 has a roller I 644-1 fixed to the pepper leaf vibrating screening screen 61 at one end, and a roller II 644-2 rolledly connected to the surface of the eccentric wheel 641 at the other end.

[0050] The sleeve 643, which guides the reciprocating motion of the connecting rod 642, is fixedly installed on the lower side of the discharge end.

[0051] Working principle:

[0052] A connecting rod 642 is vertically arranged on the high side of the inclined surface below the pepper leaf vibrating screen 61. Rollers 644 that contact the eccentric wheel 641 and the pepper leaf vibrating screen 61 are respectively arranged at both ends of the connecting rod 642. The motor drives the eccentric wheel 641 to rotate.

[0053] At this time, because the rotation point of the eccentric wheel 641 is not at the center of the circle, the rotation of the eccentric wheel 641 will cause it to move up and down. At this time, the roller II 644-2, which is rolled and connected to the eccentric wheel 641, will move up and down in the vertical direction. As the distance between the roller II 644-2 and the axis of rotation of the eccentric wheel 641 changes continuously, the connecting rod 642 moves up and down under the guidance of the sleeve 643. The connecting rod 642 drives the roller I 644-1 at the other end to move up and down, and finally the pepper leaf vibrating screen 61 fixed with the roller I 644-1 vibrates.

[0054] Among them, the branches and trunk collection box 62 is equipped with baffles on both sides that are higher than the vibrating screening net 61 for pepper leaves, so as to prevent lighter materials such as pepper leaves that have not been screened from rolling down from both sides.

[0055] As described above, the bottom of the lower end of the inclined surface of the pepper leaf vibrating screening net 61 is provided with a rotating shaft 65 that is hinged to the side of the branch collection box 62, and a pepper leaf collection box 63 is provided below the lower end of the pepper leaf vibrating screening net 61.

[0056] Working principle:

[0057] The vibration mechanism 64 causes the pepper leaf vibrating screen 61 to vibrate, thereby driving the lighter materials such as pepper leaves above to move faster to the lower end of the pepper leaf vibrating screen 61. At the same time, during the movement, the small branches can fully contact the screen and are more easily screened out by the screen of the pepper leaf vibrating screen 61, passing through the screen holes and falling into the branch collection box 62 below. The larger pepper leaves are retained on the screen surface and move quickly to the lower end of the pepper leaf vibrating screen 61 under the vibration and fall into the pepper leaf collection box 63, thus obtaining pepper leaves without impurities.

[0058] Among them, ① a rotatable constraint structure can be formed by the rotating shaft 65. When the vibration mechanism 64 drives the higher end of the pepper leaf vibrating screening mesh 61 to move up and down, the lower end is fixed to the rotation fulcrum by the rotating shaft 65. The movement is restricted to the swing range around the shaft, avoiding large bounces and offsets at the rear end due to the transmission of displacement at the upper end.

[0059] ②Among them, the pepper leaf collection box 63 is equipped with baffles on both sides that are higher than the pepper leaf vibrating screening screen 61 to prevent larger pepper leaves that have not been screened from rolling down from both sides to other areas of the pepper leaf screening unit 6.

[0060] In the above scheme, a partition 34 with several through holes is provided between the fan 31 and the air separation inlet pipe 32, and one end of the air separation inlet pipe 32 is horn-shaped.

[0061] Working principle:

[0062] The baffle 34 can intercept dust, impurities or small amounts of large particles brought in during the air intake process of the fan, and prevent impurities from entering the air separation channel and affecting the air separation effect;

[0063] Compared to straight-tube ducts, the gentle flare of the trumpet-shaped structure allows more airflow to be used for material separation.

[0064] In the above scheme, a spherical buffer chamber 7 is provided between the air inlet pipe 32 and the air separation outlet pipe 33.

[0065] Working principle:

[0066] The mixture (Sichuan peppercorns, Sichuan peppercorn leaves, small twigs, and Sichuan peppercorn seeds) falling from feed pipe 5 is initially falling rapidly due to gravity, resulting in a short contact time with the airflow. This can easily lead to insufficient separation, such as Sichuan peppercorn leaves not being blown away or small twigs being mistakenly left behind.

[0067] The volume expansion effect of the spherical buffer chamber 7 naturally extends the falling path of the material after it enters, and the airflow has more time to penetrate the material layer and accurately act on the components of different weights. The pepper leaves and small branches are fully entrained by the airflow, while the pepper shells and pepper seeds are less affected by the airflow and continue to fall along the direction of gravity.

[0068] Meanwhile, the spherical structure of the spherical buffer chamber 7 will cause some of the airflow to form a weak circulation, which can turn over and disperse the sticky materials, such as pepper leaves stuck to small branches, to avoid separation and omission caused by material clumping, and further improve the air separation accuracy.

[0069] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.

[0070] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0071] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
