Description

Technical Field

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

[0002] As a traditional agricultural product, tea processing involves multiple stages, among which sieving is a key step. The main purpose of sieving is to grade tea leaves according to their size, shape, and quality for subsequent processing and packaging. With the continuous development of the tea industry, the market demands higher and higher quality tea. In order to improve the processing efficiency and quality of tea, it is particularly important to develop a high-efficiency, precise, easy-to-operate, and low-maintenance sieving device for tea processing.

[0003] Currently, Chinese invention patent application CN 116899863B, published on December 5, 2023, discloses a tea sieving machine, including a sieving machine body; a feed inlet installed at the center of the upper end face of the sieving machine body; a mounting frame disposed on the inner wall of the sieving machine body; a sieve plate disposed within the mounting frame, the mounting frame having a mounting groove adapted to the sieve plate; at least one set of sieve holes disposed on the upper end face of the sieve plate, the sieve holes being arranged in a linear array on the end face of the sieve plate, the sieve holes being used to sieve tea leaves of different sizes; and a drive mechanism disposed on the inner wall of the sieving machine body, the drive mechanism being used to drive the sieve plate to reciprocate; causing the tea leaves on the surface of the sieve plate to reciprocate, so that smaller tea leaves mixed together will fall from the sieve holes into the collection seat, while the larger tea leaves will remain above the sieve plate, thus achieving the sieving of tea leaves.

[0004] However, during the tea sorting process, the sieve holes on the sieve plate are easily clogged by tea leaves, making it impossible to clean the sieve holes. Once the sieve holes are clogged, the tea leaves cannot pass through the sieve holes smoothly for grading, resulting in a significant decrease in sorting speed. The sorting task that should have been completed quickly will take more time, reducing production efficiency.

[0005] Therefore, it is necessary to provide a screening device for tea processing to solve the above problems. Summary of the Invention

[0040] In order to clean the tea residue inside the sieve holes after tea sieving and improve the sieving speed, the embodiments of this application provide the following solutions.

[0041] Please refer to the following: Figures 1 to 5 The system includes a tank body 1 for supporting components; a sieve plate 14 disposed on the tank body 1 for sieving tea leaves; and a cleaning component 2 disposed on the tank body 1 for cleaning tea leaves clogged in the sieve holes of the sieve plate 14. The cleaning component 2 includes a rotating component 22 disposed on the tank body 1; and a clamping component 21 arranged in a ring array on the rotating component 22 and connected to the output end of the rotating component 22 for clamping out tea leaves clogged in the sieve holes. A support frame 11 is fixedly disposed on the tank body 1. The tank body 1 is provided with an inlet 12 and an outlet 13. A connecting plate 15 is disposed on the sieve plate 14, and a vibrator 16 is disposed on the connecting plate 15.

[0042] With this setup, when the user uses the tea processing sieving device to sieve tea, by pouring the tea into the tank 1 through the feed inlet 12, the vibrator 16 is turned on. The vibrator 16 vibrates on the connecting plate 15 and drives the sieve plate 14 to vibrate, thereby speeding up the sieving process of the tea in the tank 1. After sieving, the larger tea leaves left on the upper layer of the sieve plate 14 can be removed from the feed inlet 12 by vacuum suction or tilting the tank 1. At the same time, the sieve holes on the sieve plate 14 may be blocked by the larger tea leaves left behind.

[0043] In some embodiments, please refer to the following: Figures 1 to 3The rotating component 22 includes a motor 221, which is mounted on the tank body 1; a rotating rod 222, which is mounted on the motor 221 and coaxially drives the output shaft of the motor 221; a first bevel gear 223, which is sleeved on the rotating rod 222, and a bevel gear fixing bracket 224 is fixedly connected to the first bevel gear 223, with the other end of the bevel gear fixing bracket 224 fixedly mounted on the inner wall of the tank body 1; a connecting rod 226, which is fixedly mounted on the rotating rod 222 and rotatably connected to the rotating sleeve 211; and a second bevel gear 225, which is sleeved on the connecting rod 226 and rotatably connected to the connecting rod 226, and fixedly connected to the rotating sleeve 221. The second bevel gear 225 meshes and rotates with the first bevel gear 223. A guide plate 3 is provided on the rotating rod 222 to guide the tea leaves to disperse and reduce damage to the tea leaves caused by the first bevel gear 223 and the second bevel gear 225.

[0044] With this setup, the user can clean the tea leaves remaining in the sieve holes by activating the cleaning component 2. First, the motor 221 is turned on, and the rotation of the motor 221 drives the rotating rod 222 to rotate. The rotating rod 222 is engaged with the first bevel gear 223, which is fixed to the inner wall of the tank 1 by the bevel gear fixing bracket 224. The first bevel gear 223 does not rotate with the rotation of the rotating rod 222. The rotation of the rotating rod 222 drives the clamping member 21 to rotate around the axis of the rotating rod 222 through the connecting rod 226. At the same time, through the meshing transmission between the first bevel gear 223 and the second bevel gear 225, the clamping member 21 rotates around its own axis, which facilitates the cleaning of the tea residue remaining in the sieve holes on the sieve plate 14. At the same time, a guide plate 3 is provided on the rotating rod 222 to guide the tea leaves to disperse and reduce the damage to the tea leaves caused by the first bevel gear 223 and the second bevel gear 225. Thus, driven by motor 221 and gear transmission, clamping member 21 can rotate in two ways: around the axis of rotating rod 222 and around its own axis. This design can more comprehensively cover the sieve holes, ensuring that tea residue inside the sieve holes is effectively removed. The user only needs to start motor 221, and the entire cleaning process can be completed automatically, reducing the complexity and labor intensity of manual operation and improving cleaning efficiency. This cleaning component 2 achieves efficient, stable, and uniform cleaning effect through ingenious mechanical design and automated operation. At the same time, the guide plate 3 set on rotating rod 222 can guide the tea leaves to disperse, reducing the risk of the tea leaves being damaged by the first bevel gear 223 and the second bevel gear 225 during the cleaning process. This design protects the integrity of the tea leaves and avoids unnecessary waste.

[0045] In some embodiments, please refer to the following: Figures 1 to 4The clamping member 21 includes a rotating sleeve 211, which is mounted on the rotating member 22 and connected to the output end of the rotating member 22, so that the rotating sleeve 211 rotates axially around the can body 1 while rotating axially around itself; a connecting sleeve 212, which is fitted onto the rotating sleeve 211; and a clamp 213, which is mounted on the connecting sleeve 212 and used to control the opening and closing of the clamp 213 by the tension generated by the connecting sleeve 212 during the rotation of the rotating sleeve 211, thereby clamping out the tea leaves blocking the sieve holes on the sieve plate 14. The connecting sleeve 212 includes a semi-circular outer shell 2121, which is fitted onto the rotating sleeve 211; and a rubber connector 2122, which is mounted on the semi-circular outer shell 2121, with the inner wall of the rubber connector 2122 being flush with the outer shell. The connecting sleeve 212 abuts against the cylindrical sleeve, and the rotating sleeve 211 has a groove 2111. The clamping member 213 includes: a semi-circular clamping piece 2131, which is disposed on the outer wall of the rubber connector 2122 and forms an angle with the outer wall of the rubber connector 2122 to facilitate clamping tea leaves that are spirally blocked in the sieve holes; and a square clamping piece 2132, which is disposed on the outer wall of the rubber connector 2122 and forms an angle with the outer wall of the rubber connector 2122 to facilitate clamping tea leaves that leak out from the bottom of the sieve holes. The semi-circular clamping pieces 2131 and the square clamping pieces 2132 are alternately arranged in an array on the outer wall of the rubber connector 2122. An extension piece 2133 is provided on the semi-circular clamping piece 2131, and a connecting frame 227 is provided between adjacent semi-circular outer shells 2121.

[0046] With this configuration, the rotating sleeve 211 rotates around the axis of the rotating rod 222 via the connecting rod 226, and the rotating sleeve 211 rotates around its own axis via the meshing transmission between the first bevel gear 223 and the second bevel gear 225. Simultaneously, the connecting sleeve 212 is fitted onto the outer wall of the rotating sleeve 211. Because a connecting bracket 227 is provided between adjacent connecting sleeves 212, the connecting sleeve 212 does not rotate with the rotating sleeve 211 around its own axis. The rotating sleeve 211 drives the connecting sleeve 212 to rotate around the axis of the rotating rod 222. The connecting sleeve 212 consists of a semi-circular outer shell 2121 and a rubber connector 2122. Because the rotating sleeve 211 has a groove 2111, when the rotating sleeve 211 rotates along its own axis, the groove 2111 is in contact with the rubber connector 2122, which is under weak tension. Therefore, the clamp 213 on the rubber connector 2122 is in a closed state. When the rotating sleeve 211 rotates to the arc portion in contact with the rubber connector 2122, the rubber connector 2122 is under strong tension, and the clamp 213 on the rubber connector 2122 is in an open state under tension. The rotation of the rotating sleeve 211 causes the clamp 213 to alternate between these two states, thereby removing any larger tea leaves that may have been left in the sieve holes of the sieve plate 14. The four rotating sleeves 211 initially have different angles. To facilitate better and more comprehensive cleaning of the sieve plate 14, the clamp 213 has a semi-circular clamp 2131 and a square clamp 2132. The semi-circular clamp 2131 is provided with an extension piece 2133 to facilitate clamping the tea leaves that are spirally blocked in the sieve holes. The square clamp 2132 is convenient for clamping the tea leaves that leak out from the bottom of the sieve holes. The semi-circular clamp 2131 and the square clamp 2132 are arranged alternately in an array on the outer wall of the rubber connector 2122 to facilitate more comprehensive removal of the tea leaves remaining in the sieve holes on the sieve plate 14.Thus, the four rotating sleeves 211 have different angles in the initial state. This design allows the cleaning component 2 to clean the sieve plate 14 from all angles, avoiding cleaning dead corners. The clamps 213 on the rubber connector 2122 open and close through tension changes. When the groove 2111 of the rotating sleeve 211 abuts against the rubber connector 2122, the clamps 213 are in a closed state; when the arc part abuts against the rubber connector 2122, the clamps 213 open under strong tension. This design allows the clamps 213 to automatically adjust their state according to the position of the rotating sleeve 211, effectively clamping out the tea leaves in the sieve holes. The clamps 213 are divided into semi-circular clamps 2131 and square clamps 2132. The semi-circular clamps 2131 are provided with extension pieces 2133 to facilitate clamping the tea leaves that are spirally blocked in the sieve holes; the square clamps 2132 are convenient for clamping the tea leaves that leak out from the bottom of the sieve holes. This design allows the cleaning component 2 to adapt to tea leaves of different shapes and states. The cleaning component 2 is designed to remove tea leaves from the sieve plate 14 more comprehensively, adapting to tea residue in different positions and states. The design ensures the structural stability of the cleaning component 2 by using a connecting frame 227 between adjacent connecting sleeves 212, preventing the sleeves 211 from rotating around their own axis. This design avoids structural loosening or damage caused by the rotation of the sleeves 211. The groove 2111 on the sleeve 211 and the rubber connector 2122 work together to maintain a stable tension during rotation, ensuring the effective opening and closing of the clamp 213. The semi-circular clamp 2131 and square clamp 2132 are alternately arrayed on the outer wall of the rubber connector 2122. This design allows the cleaning component 2 to more comprehensively remove tea leaves remaining in the sieve holes of the sieve plate 14, adapting to tea residue in different positions and states. The clamp 213 automatically opens and closes through tension changes, requiring no manual intervention. This design reduces the complexity and labor intensity of manual operation.

[0047] The implementation principle of a tea processing sieving device in this application embodiment is as follows: When the user uses the tea processing sieving device to sieve tea, by pouring the tea into the tank 1 from the feed inlet 12, the vibrator 16 is turned on. The vibrator 16 vibrates on the connecting plate 15 and drives the sieve plate 14 to vibrate, thereby speeding up the sieving work of the tank 1 on the tea. After sieving, the larger tea leaves left on the upper layer of the sieve plate 14 can be taken out from the feed inlet 12 by vacuum suction or tilting the tank 1. At the same time, the sieve holes on the sieve plate 14 may be blocked by the larger tea leaves left behind.The user cleans the tea leaves remaining in the sieve holes by activating the cleaning component 2. First, the motor 221 is turned on, and the rotation of the motor 221 drives the rotating rod 222 to rotate. The rotating rod 222 is sleeved with the first bevel gear 223, which is fixed to the inner wall of the tank 1 by the bevel gear fixing bracket 224. The first bevel gear 223 does not rotate with the rotation of the rotating rod 222. The rotation of the rotating rod 222 drives the rotating sleeve 211 to rotate around the axis of the rotating rod 222 through the connecting rod 226. At the same time, through the meshing transmission between the first bevel gear 223 and the second bevel gear 225, the rotating sleeve 211 rotates around its own axis, facilitating the cleaning of the sieve plate 14. The tea residue remaining in the sieve holes is cleaned. The rotating sleeve 211 rotates around the rotating rod 222 via the connecting rod 226, and the first bevel gear 223 and the second bevel gear 225 mesh together, causing the rotating sleeve 211 to rotate around its own axis. Simultaneously, the connecting sleeve 212 is fitted onto the outer wall of the rotating sleeve 211. Because a connecting frame 227 is provided between adjacent connecting sleeves 212, the connecting sleeve 212 does not rotate with the rotating sleeve 211 around its own axis. The rotating sleeve 211 drives the connecting sleeve 212 to rotate around the rotating rod 222. The connecting sleeve 212 is divided into a semi-circular outer shell 212. 1. Regarding the rubber connector 2122, since the rotating sleeve 211 has a groove 2111, when the rotating sleeve 211 rotates along its own axis, the groove 2111 of the rotating sleeve 211 is in contact with the rubber connector 2122, and the rubber connector 2122 is in a state of weak tension. Therefore, the clamp 213 on the rubber connector 2122 is in a closed state. When the rotating sleeve 211 rotates to the arc portion in contact with the rubber connector 2122, the rubber connector 2122 is in a state of strong tension. Therefore, the clamp 213 on the rubber connector 2122 is in an open state under tension. The rotation of the rotating sleeve 211 causes the clamp 213 to be in two states... The system continuously alternates between these states to remove larger tea leaves that may be left in the sieve holes of the sieve plate 14. The four rotating sleeves 211 are at different angles in the initial state, facilitating a more comprehensive cleaning of the sieve plate 14. The clamping member 213 has semi-circular clamping pieces 2131 and square clamping pieces 2132. The semi-circular clamping pieces 2131 are equipped with extension pieces 2133 to easily hold tea leaves that are spirally blocked in the sieve holes. The square clamping pieces 2132 are used to hold tea leaves that leak out from the bottom of the sieve holes. The semi-circular clamping pieces 2131 and square clamping pieces 2132 are arranged alternately in an array on the outer wall of the rubber connector 2122, facilitating a more thorough removal of tea leaves remaining in the sieve holes of the sieve plate 14.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
