Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and in particular to a screening device for tea processing. Background Art

[0002] As a traditional agricultural product, the processing of tea involves multiple links. Among them, screening is one of the key steps. The main purpose of screening is to classify tea according to its size, shape and quality for subsequent processing and packaging. With the continuous development of the tea industry, the market has higher and higher requirements for the quality of tea. In order to improve the processing efficiency and quality of tea, it is particularly important to develop a screening device for tea processing that is efficient, accurate, easy to operate and has low maintenance costs.

[0003] At present, a Chinese invention patent application with a publication date of December 05, 2023 and a publication number of CN 116899863B proposes a tea screening machine, including a screening machine body; a feed inlet installed at the center of the upper end face of the screening machine body; an installation frame arranged on the inner wall of the screening machine body, a sieve plate arranged in the installation frame, and an installation groove adapted to the sieve plate is opened in the installation frame; at least one group of sieve holes opened on the upper end face of the sieve plate, and the sieve holes are linearly arrayed on the end face of the sieve plate, and the sieve holes are used to screen tea of different sizes; a driving mechanism arranged on the inner wall of the screening machine body, and the driving mechanism is used to drive the sieve plate to move back and forth; so that the tea on the surface of the sieve plate vibrates back and forth, and the smaller particle size tea mixed together will fall into the recovery seat through the sieve holes, while the tea with relatively complete specifications will be above the sieve plate, thus realizing the screening of tea.

[0004] However, during the screening process of tea, the sieve holes on the sieve plate are easily blocked by tea, and the sieve holes on the sieve plate cannot be cleaned. After the sieve holes are blocked, the tea cannot pass through the sieve holes smoothly for grading, resulting in a significant decrease in the screening speed. The originally fast screening task will take more time, reducing the production efficiency.

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

[0019] In order to clean the residues of tea leaves in the sieve holes on the sieve plate after the sieving of tea leaves and improve the sieving speed, the embodiments of the present application provide the following solutions.

[0020] Please refer to Figures 1 to 5 together, which includes a tank body 1 for carrying parts; a sieve plate 14 arranged on the tank body 1 for sieving tea leaves; a cleaning assembly 2 arranged on the tank body 1 for cleaning the blocked tea leaves in the sieve holes on the sieve plate 14; wherein, the cleaning assembly 2 includes a rotating member 22 arranged on the tank body 1; a clamping member 21 arranged in an annular array on the rotating member 22 and connected to the output end of the rotating member 22 for clamping out the blocked tea leaves in the sieve holes. A support frame 11 is fixedly arranged on the tank body 1, a feed inlet 12 and a discharge outlet 13 are arranged on the tank body 1, a connecting plate 15 is arranged on the sieve plate 14, and a vibrator 16 is arranged on the connecting plate 15.

[0021] With such a setting, when the user uses the tea processing sieving device to sieve tea leaves, when pouring the tea leaves into the interior of the tank body 1 from the feed inlet 12, by turning on the vibrator 16, while the vibrator 16 vibrates on the connecting plate 15, it drives the sieve plate 14 to vibrate, and at the same time speeds up the sieving work of the tank body 1 on the tea leaves. After the sieving is completed, the larger tea leaves left on the upper layer of the sieve plate 14 can be taken out from the feed inlet 12 by means of vacuum suction or tilting the tank body 1 to pour, and at the same time, the sieve holes on the sieve plate 14 may be blocked by the larger tea leaves left.

[0022] In some embodiments, please refer to Figures 1 to 3 together. The rotating member 22 includes a motor 221 arranged on the tank body 1; a rotating rod 222 arranged on the motor 221 and coaxially driven with the output shaft of the motor 221; a first bevel gear 223 sleeved on the rotating rod 222, and a bevel gear fixing frame 224 is fixedly connected to the first bevel gear 223, and the other end of the bevel gear fixing frame 224 is fixedly arranged on the inner wall of the tank body 1; a connecting rod 226 fixedly arranged on the rotating rod 222 and rotatably connected to the rotating sleeve 211; a second bevel gear 225 sleeved on the connecting rod 226, rotatably connected to the connecting rod 226 and fixedly connected to the rotating sleeve 221, and the second bevel gear 225 meshes and rotates with the first bevel gear 223. A diversion plate 3 is arranged on the rotating rod 222 for guiding the dispersion of tea leaves and reducing the damage to the tea leaves by the first bevel gear 223 and the second bevel gear 225.

[0023] · With such a setting, 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. The rotation of the motor 221 drives the rotation of the rotating rod 222. The rotating rod 222 is sleeved with the first bevel gear 223. The first bevel gear 223 is fixed to the inner wall of the tank body 1 through the bevel gear fixing frame 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 rotating rod 222 as the axis 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 to facilitate the cleaning of the tea residue in the sieve holes on the sieve plate 14. At the same time, a diversion plate 3 is provided on the rotating rod 222 to guide the dispersion of the tea leaves and reduce the damage to the tea leaves by the first bevel gear 223 and the second bevel gear 225. In this way, through the drive of the motor 221 and gear transmission, the clamping member 21 can perform double rotations, rotating around the axis of the rotating rod 222 and rotating around its own axis. This design can more comprehensively cover the sieve holes, ensure that the tea residue in the sieve holes is effectively removed. The user only needs to start the motor 221, and the entire cleaning process can be automatically completed, reducing the complexity and labor intensity of manual operation and improving the cleaning efficiency. This cleaning component 2 achieves an efficient, stable, and uniform cleaning effect through a clever mechanical design and automated operation. At the same time, the diversion plate 3 provided on the rotating rod 222 can guide the dispersion of the tea leaves and reduce the risk of damage to the tea leaves 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.

[0024] In some embodiments, please also refer to Figures 1 to 4, the clamping member 21 includes a rotating sleeve 211 disposed on the rotating member 22 and connected to the output end of the rotating member 22, enabling the rotating sleeve 211 to rotate axially about the tank body 1 while the rotating sleeve 211 rotates axially about itself; a connecting sleeve 212 sleeved on the rotating sleeve 211; and a clamping member 213 disposed on the connecting sleeve 212 for controlling the opening and closing of the clamping member 213 by the tension generated in the connecting sleeve 212 during the rotation of the rotating sleeve 211, thereby clamping out the blocked tea leaves in the sieve holes on the sieve plate 14. The connecting sleeve 212 includes a semi-circular outer shell 2121 sleeved on the rotating sleeve 211; and a rubber connecting member 2122 disposed on the semi-circular outer shell 2121, the inner wall of the rubber connecting member 2122 abuts against the barrel of the connecting sleeve 212. A groove 2111 is formed on the rotating sleeve 211. The clamping member 213 includes a semi-circular clamping piece 2131 disposed on the outer wall of the rubber connecting member 2122 and forming an angle with the outer wall of the rubber connecting member 2122, facilitating the clamping of the tea leaves spirally blocked in the sieve holes; and a square clamping piece 2132 disposed on the outer wall of the rubber connecting member 2122 and forming an angle with the outer wall of the rubber connecting member 2122, facilitating the clamping of the tea leaves leaking from the bottom of the sieve holes. Among them, 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 connecting member 2122. An extension piece 2133 is provided on the semi-circular clamping piece 2131. A connecting frame 227 is provided between adjacent semi-circular outer shells 2121, With such a setting, when the rotating sleeve 211 is driven by the connecting rod 226 to rotate around the rotating rod 222 as the axis, and through the meshing transmission between the first bevel gear 223 and the second bevel gear 225, while driving the rotating sleeve 211 to rotate around its own axis, the connecting sleeve 212 is sleeved on the outer wall of the rotating sleeve 211. Since there is a connecting frame 227 between two adjacent connecting sleeves 212, the connecting sleeve 212 does not rotate with the rotation of the rotating sleeve 211 around its own axis. The rotating sleeve 211 drives the connecting sleeve 212 to rotate around the rotating rod 222 as the axis. At the same time, the connecting sleeve 212 is divided into a semi-circular housing 2121 and a rubber connecting piece 2122. Since there is a groove 2111 on the rotating sleeve 211, during the rotation of the rotating sleeve 211 along its own axis, when the groove 2111 of the rotating sleeve 211 abuts against the rubber connecting piece 2122, the rubber connecting piece 2122 is in a state of weak tension, and the clip 213 on the rubber connecting piece 2122 is in a closed state. When the rotating sleeve 211 rotates to the state where the arc part abuts against the rubber connecting piece 2122, the rubber connecting piece 2122 is in a state of strong tension, and the clip 213 on the rubber connecting piece 2122 is in an open state under the tension state. The rotation of the rotating sleeve 211 causes the clip 213 to continuously alternate between the two states, thereby clamping out the larger tea leaves that may be left in the sieve holes on the sieve plate 14. Among them, the four rotating sleeves 211 have different angles in the initial state, which is convenient for better cleaning the sieve plate 14 in all aspects. At the same time, the clip 213 has a semi-circular clip piece 2131 and a square clip piece 2132. The semi-circular clip piece 2131 is provided with an extension piece 2133, which is convenient for clamping the tea leaves that are spirally blocked in the sieve holes. The square clip piece 2132 is convenient for clamping the tea leaves leaking from the bottom of the sieve holes. The semi-circular clip piece 2131 and the square clip piece 2132 are alternately arranged in an array on the outer wall of the rubber connecting piece 2122, which is convenient for more comprehensively clamping out 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 enables the cleaning assembly 2 to clean the sieve plate 14 comprehensively, avoiding cleaning dead corners. The clip 213 on the rubber connecting piece 2122 opens and closes through tension change. When the groove 2111 of the rotating sleeve 211 abuts against the rubber connecting piece 2122, the clip 213 is in a closed state; when the arc part abuts against the rubber connecting piece 2122, the clip 213 opens under the action of strong tension. This design enables the clip 213 to automatically adjust its state according to the position of the rotating sleeve 211, effectively clamping out the tea leaves in the sieve holes. The clip 213 is divided into a semi-circular clip 2131 and a square clip 2132. An extension piece 2133 is provided on the semi-circular clip 2131 to facilitate clamping the tea leaves with spiral blockage in the sieve holes; the square clip 2132 is convenient for clamping the tea leaves leaking from the bottom of the sieve holes. This design enables the cleaning assembly 2 to adapt to tea residues of different shapes and states, improving the pertinence of cleaning. Since a connecting frame 227 is provided between two adjacent connecting sleeves 212, the connecting sleeve 212 does not rotate with the rotation of the rotating sleeve 211 around its own axis. This design ensures the structural stability of the cleaning assembly 2, avoiding structural loosening or damage caused by the rotation of the rotating sleeve 211. The matching design of the groove 2111 on the rotating sleeve 211 and the rubber connecting piece 2122 enables the cleaning assembly 2 to maintain a stable tension state during rotation, ensuring the effective opening and closing of the clip 213. The semi-circular clip 2131 and the square clip 2132 are alternately arranged in an array on the outer wall of the rubber connecting piece 2122. This design enables the cleaning assembly 2 to more comprehensively clamp out the tea leaves remaining in the sieve holes on the sieve plate 14, adapting to tea residues in different positions and states. The clip 213 realizes automatic opening and closing through tension change without manual intervention. This design reduces the complexity and labor intensity of manual operation.

[0025] The implementation principle of a screening device for tea processing in an embodiment of this application is as follows: When the user uses this screening device for tea processing to screen tea, when pouring the tea into the tank body 1 from the feed inlet 12, by turning on the vibrator 16, while the vibrator 16 vibrates on the connecting plate 15, it drives the sieve plate 14 to vibrate, simultaneously accelerating the screening work of the tank body 1 on the tea. After the screening is completed, the larger tea left on the upper layer of the sieve plate 14 can be taken out from the feed inlet 12 by means of vacuum suction or tilting the tank body 1 to pour it. At the same time, the sieve holes on the sieve plate 14 may be blocked by the larger tea left behind;The user starts the cleaning component 2 to clean the tea leaves remaining in the sieve holes. First, the motor 221 is turned on. The rotation of the motor 221 drives the rotation of the rotating rod 222. The rotating rod 222 is sleeved with the first bevel gear 223. The first bevel gear 223 is fixed to the inner wall of the tank body 1 through the bevel gear fixing frame 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 rotating rod 222 as the axis 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 to facilitate the cleaning of the tea residue remaining in the sieve holes on the sieve plate 14. When the rotating sleeve 211 is driven by the connecting rod 226 to rotate around the rotating rod 222 as the axis, and through the meshing transmission between the first bevel gear 223 and the second bevel gear 225 to drive the rotating sleeve 211 to rotate around its own axis, the connecting sleeve 212 is sleeved on the outer wall of the rotating sleeve 211. Since there is a connecting frame 227 between two adjacent connecting sleeves 212, the connecting sleeve 212 does not rotate with the rotation of the rotating sleeve 211 around its own axis. The rotating sleeve 211 drives the connecting sleeve 212 to rotate around the rotating rod 222 as the axis. At the same time, the connecting sleeve 212 is divided into a semi-circular shell 2121 and a rubber connecting piece 2122. Since there is a groove 2111 on the rotating sleeve 211, when the groove 2111 of the rotating sleeve 211 abuts against the rubber connecting piece 2122 during the rotation of the rotating sleeve 211 along its own axis, the rubber connecting piece 2122 is in a state of weak tension, and the clip 213 on the rubber connecting piece 2122 is in a closed state. When the rotating sleeve 211 rotates to the state where the arc part abuts against the rubber connecting piece 2122, the rubber connecting piece 2122 is in a state of strong tension, and the clip 213 on the rubber connecting piece 2122 is in an open state under the tension state. The rotation of the rotating sleeve 211 causes the clip 213 to alternate between two states, so as to clamp out the larger tea leaves that may be left in the sieve holes on the sieve plate 14. The angles of the four rotating sleeves 211 are different in the initial state, which is convenient for better cleaning the sieve plate 14 in all aspects. At the same time, the clip 213 has a semi-circular clip 2131 and a square clip 2132. The semi-circular clip 2131 is provided with an extension piece 2133, which is convenient for clamping the tea leaves that are spirally blocked in the sieve holes. The square clip 2132 is convenient for clamping the tea leaves leaking from the bottom of the sieve holes. The semi-circular clip 2131 and the square clip 2132 are alternately arranged in an array on the outer wall of the rubber connecting piece 2122, which is convenient for more comprehensively clamping out the tea leaves remaining in the sieve holes on the sieve plate 14.;

[0026] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
