Description

Technical Field

[0001] This application relates to the field of green tea processing technology, and in particular to a sorting device for green tea processing. Background Technology

[0002] Green tea is one of the main types of tea in China. It refers to a beverage made from the new leaves or buds of the tea plant, which are not fermented and are processed through steps such as fixation, shaping, and drying. Because the finished product retains more of the green color of the fresh tea leaves and the brewed tea soup retains more of the green hue of the fresh tea leaves, it is becoming increasingly popular.

[0003] In the tea processing process, the processed tea needs to be divided into different grades. Currently, the main methods for sorting and grading are manual selection or sorting equipment. Manual operation is not only labor-intensive and inefficient, but the sorting effect is also greatly affected by human factors. On the other hand, the existing green tea sorting equipment has a complex structure, is inconvenient to operate, and has low sorting efficiency. Utility Model Content

[0004] In order to improve the problem of low sorting efficiency in green tea sorting operations, this application provides a sorting device for green tea processing.

[0005] The sorting device for green tea processing provided in this application adopts the following technical solution:

[0006] A sorting device for green tea processing includes a mounting base, a sorting box, and a driving mechanism. The sorting box is slidably connected to the mounting base, and a feed inlet is provided at the top of the sorting box. The driving mechanism is located on the mounting base and is used to drive the sorting box to slide back and forth. A vibrating frame is provided inside the sorting box, and a first sieve plate, a second sieve plate, and a third sieve plate are arranged sequentially from top to bottom on the vibrating frame. A lifting mechanism is provided on the sorting box for driving the vibrating frame to move up and down reciprocally.

[0007] By adopting the above technical solution, the drive mechanism drives the sorting box to slide back and forth on the mounting base, which allows the green tea entering the feed inlet of the sorting box to be initially dispersed and spread evenly on the first screen plate during the sliding process of the sorting box. At the same time, the lifting mechanism drives the vibrating frame to move up and down back and forth, causing the first screen plate, the second screen plate and the third screen plate to move up and down back and forth, so that the green tea continuously jumps and rolls on the multi-layer screen plate, thereby achieving effective sorting of tea leaves of different sizes and improving sorting efficiency.

[0008] Optionally, the drive mechanism includes a rotary motor, a half gear, a first rack, and a second rack. The rotary motor is vertically mounted at the bottom of the sorting box. The half gear is connected to the rotating shaft of the rotary motor. The first rack and the second rack are parallel to each other and mounted on a mounting base. The half gear is positioned between the first rack and the second rack. During one revolution of rotation, the half gear meshes with the first rack and the second rack, respectively.

[0009] By adopting the above technical solution, the rotating motor drives the half gear to rotate. During one revolution of the half gear, it meshes with the first rack and the second rack, which are set parallel to each other on the mounting base, thereby driving the sorting box to slide back and forth on the mounting base, realizing the periodic movement of the sorting box, which helps to improve the efficiency and effect of green tea sorting.

[0010] Optionally, the lifting mechanism includes a cam, a pressing block, a limiting block, and a compression spring. The pressing block is located at the bottom of the vibration frame and has a chamfered surface at its bottom. The rotating motor is a double-headed motor. The cam is located on the rotating shaft at the top of the rotating motor, and the peripheral wall of the cam abuts against the chamfered surface. The limiting block is movably inserted into the inner wall of the sorting box along the lateral direction. The bottom of the compression spring is connected to the top of the vibration frame, and the top of the compression spring abuts against the bottom of the limiting block.

[0011] By adopting the above technical solution, the rotating motor is a dual-head motor. Its top rotating shaft drives the cam to rotate. The cam's peripheral wall abuts against the inclined surface at the bottom of the pressing block. As the cam rotates, the pressing block drives the vibrating frame to rise under the action of the cam. At this time, the compression spring is compressed. When the cam continues to rotate and no longer applies force to the pressing block, the compression spring rebounds and drives the vibrating frame to fall. In this way, the reciprocating lifting and lowering of the vibrating frame is realized, so that the green tea on the first sieve plate, the second sieve plate and the third sieve plate is sorted under the action of vibration.

[0012] Optionally, an adjusting bolt is rotatably connected to the limiting block, and the adjusting bolt is threadedly connected to the side wall of the sorting box.

[0013] By adopting the above technical solution, rotating the adjusting bolt will cause it to move linearly along the thread direction during rotation, since the adjusting bolt is threadedly connected to the side wall of the sorting box. Also, because the adjusting bolt is rotatably connected to the limiting block, the adjusting bolt will drive the limiting block to move laterally, thereby adjusting the position of the limiting block to meet different usage requirements.

[0014] Optionally, a push plate is slidably connected to one side of the top of the sorting box, and a collection box is provided on the other side of the sorting box; slots are provided on the side wall of the vibration frame below the first screen plate, the second screen plate and the third screen plate, and the shape of the slot matches the shape of the limiting block.

[0015] By adopting the above technical solution, after sorting, the vibrating frame is lifted so that each sieve plate is flush with the top of the sorting box. The horizontal sliding push plate can push the tea leaves remaining on each sieve plate to the collection box for collection, which is convenient for cleaning. In addition, since the side wall of the vibrating frame has slots that match the shape of the limiting block under the first, second and third sieve plates, when it is necessary to clean or replace the sieve plates, the limiting block can be inserted into the slot to fix the vibrating frame, which is convenient for operation.

[0016] Optionally, the bottom of the push plate is provided with a brush, which abuts against the top of the sorting box.

[0017] By adopting the above technical solution, the pusher plate pushes the tea leaves on the top of each sieve plate into the collection box, while the brush can clean the tea leaves remaining on the top of each sieve plate, thus preventing the sieve plates from clogging.

[0018] Optionally, the vibration frame is provided with a handle at the top.

[0019] By adopting the above technical solution, when maintenance or cleaning of the vibrating frame is required, the operator can hold the handle and apply an upward pulling force to lift the vibrating frame smoothly from the sorting box, which facilitates the corresponding operations on the vibrating frame and the first, second, and third screen plates on it.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The drive mechanism drives the sorting box to slide back and forth, so that the green tea is initially dispersed and spread evenly on the first sieve plate. The lifting mechanism drives the vibrating frame to move up and down back and forth, so that the tea leaves are in full contact with the sieve plate. The green tea leaves jump and roll continuously on the multi-layer sieve plate, thereby achieving effective sorting of tea leaves of different sizes and improving sorting efficiency.

[0022] 2. The rotating motor, half gear, first rack and second rack are configured to rotate the half gear. During one rotation, the half gear meshes with the first rack and second rack, which are set parallel to each other on the mounting base. This drives the sorting box to slide back and forth on the mounting base, realizing the periodic movement of the sorting box, which helps to improve the efficiency and effect of green tea sorting.

[0023] 3. The rotating motor adopts a dual-head motor, which, together with the cam, pressing block, limit block and compression spring, drives the cam to rotate. The cam's peripheral wall periodically abuts against the inclined surface, thereby realizing the reciprocating lifting and lowering of the vibrating frame. By sharing a single rotating motor, power costs are saved. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a sorting device for green tea processing. (Refer to...) Figure 1-2 The green tea processing sorting device includes a mounting base 1, a sorting box 2, a drive mechanism, a vibrating frame 3, and a lifting mechanism. The mounting base 1 is the fundamental support structure of the entire device. It can be made of metal materials such as stainless steel, possessing sufficient strength and stability to ensure the device does not shake during operation. The sorting box 2 is slidably connected to the mounting base 1 laterally. The sorting box 2 is the main area for sorting tea leaves. It has a feed inlet at the top for placing the tea leaves to be sorted into the box. The drive mechanism, located on the mounting base 1, drives the sorting box 2 to slide back and forth.

[0031] A vibrating frame 3 is installed inside the sorting box 2. From top to bottom, a first screen plate 31, a second screen plate 32, and a third screen plate 33 are fixedly connected to the vibrating frame 3. These screen plates have different screen aperture sizes, with the first screen plate 31 having the largest aperture and the third screen plate 33 having the smallest. The vibrating frame 3 is the structure for mounting the screen plates. It can be a metal frame structure with sufficient strength and rigidity to ensure the stability of the screen plates during vibration. A handle 34 is provided at the top of the vibrating frame 3, allowing operators to easily remove the vibrating frame 3 from the sorting box 2 for cleaning or screen plate replacement. The handle 34 can be made of bent metal rod welded to the top of the vibrating frame 3. A lifting mechanism is used to drive the vibrating frame 3 to reciprocate up and down within the sorting box 2.

[0032] In use, the green tea to be sorted enters the sorting box 2 through the feed inlet at the top of the sorting box 2 and falls onto the first sieve plate 31. The drive mechanism drives the sorting box 2 to slide back and forth on the mounting base 1, which allows the green tea entering the feed inlet of the sorting box 2 to be initially dispersed and spread evenly on the first sieve plate 31 during the sliding process of the sorting box 2, making the tea leaves more evenly distributed on the sieve plate. At the same time, the lifting mechanism drives the vibrating frame 3 to move up and down, causing the first sieve plate 31, the second sieve plate 32 and the third sieve plate 33 to move up and down, making the green tea leaves jump and roll continuously on the multi-layer sieve plates, increasing the contact opportunities between the tea leaves and the sieve plates. Green tea with a particle size larger than the sieve holes of the first sieve plate 31 remains on the first sieve plate 31, while green tea with a particle size smaller than the sieve holes of the first sieve plate 31 falls onto the second sieve plate 32. Similarly, since the sieve holes of the first sieve plate 31 are the largest and the sieve holes of the third sieve plate 33 are the smallest, green tea with different particle sizes can be sieved through each sieve plate, thereby achieving a more comprehensive and effective sorting of tea leaves of different sizes and improving sorting efficiency.

[0033] For example, refer to Figure 2 The drive mechanism includes a rotary motor 21, a half gear 22, a first rack 23, and a second rack 24. The rotary motor 21 is vertically fixed to the inner wall of the bottom of the sorting box 2. The half gear 22 is connected to the rotating shaft of the rotary motor 21. When the rotary motor 21 starts, the half gear 22 rotates with the rotating shaft. The first rack 23 and the second rack 24 are parallel to each other and fixedly installed on the mounting base 1. The half gear 22 is located between the first rack 23 and the second rack 24. During one revolution of the half gear 22, it meshes with the first rack 23 and the second rack 24 respectively. When the half gear 22 meshes with the first rack 23, it drives the sorting box 2 to slide in one direction; when the half gear 22 meshes with the second rack 24, it drives the sorting box 2 to slide in the opposite direction, thereby realizing the reciprocating sliding of the sorting box 2.

[0034] For example, the lifting mechanism includes a cam 25, a pressing block 35, a limiting block 4, and a compression spring 36. The pressing block 35 is located at the bottom of the vibrating frame 3, and its bottom has a chamfered surface 37. The rotating motor 21 is a dual-head motor, with a cam 25 on its top rotating shaft. The peripheral wall of the cam 25 abuts against the chamfered surface 37. When the rotating motor 21 rotates, the cam 25 rotates continuously, and its peripheral wall contacts the chamfered surface 37 of the pressing block 35, pushing the pressing block 35, thereby causing the vibrating frame 3 to rise. The limiting block 4 is movably inserted laterally into the inner wall of the sorting box 2. The bottom of the compression spring 36 is connected to the top of the vibrating frame 3, and its top abuts against the bottom of the limiting block 4. When the cam 25 rotates to a certain position and no longer pushes the pressing block 35, the vibrating frame 3 descends under the action of the compression spring 36, thereby realizing the reciprocating lifting and lowering of the vibrating frame 3. By using a dual-head motor for the rotating motor 21, a single rotating motor 21 is used, saving power costs.

[0035] Reference Figure 3 An adjusting bolt 41 is rotatably connected to the limiting block 4, and the adjusting bolt 41 is threadedly connected to the side wall of the sorting box 2. By rotating the adjusting bolt 41, the position of the limiting block 4 can be adjusted, so that the limiting block 4 does not restrict the upward movement of the vibrating frame 3. After sorting, the tea leaves remaining on each screen plate can be lifted out of the top of the sorting box 2 by lifting the vibrating frame 3, which is convenient for collecting the sorted tea leaves.

[0036] Furthermore, refer to Figure 1 A push plate 5 is horizontally slidably connected to one side of the top of the sorting box 2. A brush 51 is provided at the bottom of the push plate 5, and the brush 51 abuts against the top of the sorting box 2. A collection box 6 is provided on the other side of the sorting box 2. Lifting the vibrating frame 3 makes each sieve plate flush with the top of the sorting box 2. The push plate 5 can be slid horizontally to push the tea leaves remaining on each sieve plate to the collection box 6 for collection, which is convenient for cleaning.

[0037] In addition, refer to Figure 3 To ensure the stability of the vibrating frame 3 when cleaning the tea leaves remaining on each sieve plate, slots 38 matching the shape of the limiting blocks 4 are provided on the side wall of the vibrating frame 3 below the first sieve plate 31, the second sieve plate 32, and the third sieve plate 33. When it is necessary to clean or replace the sieve plates, the adjusting bolts 41 can be rotated to insert the limiting blocks 4 into the slots 38 to fix the position of the vibrating frame 3, making operation convenient.

[0038] The implementation principle of the sorting device for green tea processing in this embodiment is as follows: When in use, the green tea to be sorted enters the sorting box 2 through the feed inlet at the top of the sorting box 2 and falls onto the first screen plate 31. The double-headed motor is started to drive the half gear 22 to rotate. During the rotation of the half gear 22, it meshes with the first rack 23 and the second rack 24 respectively. When the half gear 22 meshes with the first rack 23, it will drive the sorting box 2 to slide in one direction. When the half gear 22 meshes with the second rack 24, it will drive the sorting box 2 to slide in the opposite direction, thereby realizing the reciprocating sliding of the sorting box 2, thereby driving each screen plate to slide back and forth, so that the tea leaves are more evenly distributed on the screen plate. Simultaneously, the dual-head motor drives the cam 25 to rotate. The rotation of the cam 25 causes its peripheral wall to continuously abut against the inclined surface 37, pushing the pressing block 35. Under the action of the compression spring 36, the vibrating frame 3 reciprocates, thereby driving each sieve plate to reciprocate, allowing the green tea to continuously jump and tumble on the multi-layer sieve plates, increasing the contact opportunity between the tea leaves and the sieve plates. During the movement of the green tea on each sieve plate, a more comprehensive and effective sorting of tea leaves of different sizes is achieved, improving sorting efficiency. After sorting, the vibrating frame 3 is lifted by the handle 34, making the top of each sieve plate flush with the top of the sorting box 2. Pushing the push plate 5 allows the different grades of green tea remaining on each sieve plate to be collected separately, improving collection efficiency.

[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
