Description

Technical Field

[0001] This utility model relates to the field of tea shaking machines, specifically a tea shaking machine. Background Technology

[0002] A tea shaking machine is a key piece of equipment in the tea-making process, primarily used in the shaking process. Shaking is an indispensable step in tea production, influencing the physicochemical changes of tea leaves through mechanical motion and friction, thereby affecting the quality of the tea. Specifically, mechanical motion enhances the transport function of the leaf tissues, harmonizes the flavor compounds in the tea infusion, and produces an internal effect; while mechanical friction causes damage to leaf cells, promotes the enzymatic oxidation of tea polyphenols, and induces aroma, producing an external effect.

[0003] In the prior art, such as in CN215123961U, a tea shaking machine is disclosed, which includes a shaking cage, a rotating device, and multiple walls inside the shaking cage. The walls have an arc-shaped structure, and the thickness of the walls gradually increases from one side to the other side. The thinner side of the wall is connected to the thicker side of the other wall. The multiple walls are connected to each other to form the circular inner wall of the shaking cage, and the thinner side of each of the multiple walls has the same center.

[0004] While the aforementioned patent can improve the turning effect of tea leaves, the tea leaves are passively scattered by the stepped walls of the rotating shaker during the turning process. This results in low turning efficiency and easy damage to the leaves. The single rotational motion leads to insufficient turning of the tea leaves and the technical defects of relying on gravity for passive scattering. Therefore, a tea shaking machine is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, during tea leaf turning, the tea leaves are passively scattered by relying solely on the stepped walls of the rotating cage, resulting in low turning efficiency and easy damage to the leaves. This invention proposes a tea leaf shaking machine to overcome these technical defects, such as insufficient tea leaf turning due to a single rotational motion and reliance on gravity for passive scattering.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A tea shaking machine of this utility model includes a side plate A; both ends of the side plate A are provided with fixed square rods and one end of the fixed square rods is provided with a side plate B; a drive motor is provided in the middle of the other side of the side plate A; the output end of the drive motor is fixedly connected to a rotating wheel; a rocker arm is movably connected to one side of the top of the rotating wheel; a connecting rod is fixedly connected to the bottom of one end of the rocker arm; a U-shaped plate is movably connected to the bottom of the connecting rod; a shaking cylinder is fixedly connected to the bottom of the U-shaped plate; fixed blocks are provided at the four corners of the top surface of the shaking cylinder, and a sliding square ring is provided at the top of the fixed blocks; the sliding square ring is slidably connected to the surface of the fixed square rod; fixed plates are horizontally symmetrically arranged on the inner sidewalls of both ends of the inside of the shaking cylinder, and a clamping plate assembly is movably connected to one end of the fixed plate; an inclined plate is provided at one end of the clamping plate assembly; the inclined plates are symmetrically arranged oppositely on both sides inside the shaking cylinder; a feeding hopper is provided at the top of one end of the shaking cylinder.

[0007] Preferably, the other end of the rocker is provided with an openable cover, the cover being hinged to the rocker and the contact surface being provided with a sealing strip.

[0008] Preferably, the clamping plate assembly consists of two parallel elastic metal plates, and the surface of the inclined plate is distributed with hemispherical protrusions.

[0009] Preferably, a needle roller bearing is provided at the movable connection between the rocker arm and the rotary wheel, and a self-lubricating bushing is provided at the movable connection between the connecting rod and the U-shaped plate.

[0010] Preferably, the fixed block and the sliding square ring are fastened together by bolts, and the inner wall of the sliding square ring is fitted with a polyoxymethylene wear-resistant bushing.

[0011] Preferably, the maximum swing angle of the inclined plate is 30°-45°, and its bottom edge maintains a distance from the inner wall of the rocker.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves the horizontal reciprocating swaying function of the shaker along a fixed square rod through the transmission design of the drive motor, the rotating wheel and the rocker arm. It solves the problem of insufficient tumbling and damage to the leaves caused by the passive throwing of tea leaves by gravity in the existing rotary shaking machine. Specifically, through the elastic movable connection structure of the horizontally symmetrical inclined plate and the clamping plate group, when the shaker reciprocates, the inclined plate swings up and down around the clamping plate group due to inertia (maximum swing angle 30°-45°). The hemispherical protrusion structure on its surface actively pushes the tea leaves to form an upward throwing force, so that the tea leaves are fully mixed under the dual motion of horizontal shaking and vertical tumbling, and the tumbling efficiency is improved.

[0014] 2. This utility model ensures the smooth operation of the rocker drum through the sliding guide mechanism of the fixed square rod and the sliding square ring. The polyoxymethylene wear-resistant bushing on the inner wall of the sliding square ring reduces friction loss. The needle roller bearing and self-lubricating bushing at the rocker arm connection significantly reduce the wear of transmission components. Ultimately, while improving the uniformity of shaking, it extends the service life of the equipment and overcomes the fundamental defect of traditional technology that relies on a single rotational motion for turning.

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figures 1-4As shown, a tea shaking machine includes a side plate A 1; fixed square rods 2 are provided at both ends of the side plate A 1, and a side plate B 3 is provided at one end of the fixed square rods 2; a drive motor 4 is provided in the middle of the other side plate A 1; a rotating wheel 5 is fixedly connected to the output end of the drive motor 4; a rocker arm 6 is movably connected to one side of the top of the rotating wheel 5; a connecting rod 7 is fixedly connected to the bottom of one end of the rocker arm 6; a U-shaped plate 8 is movably connected to the bottom end of the connecting rod 7; and a shaking cylinder is fixedly connected to the bottom of the U-shaped plate 8. 9. Fixing blocks 10 are provided at the four corners of the top surface of the rocker cylinder 9, and a sliding square ring 11 is provided at the top of the fixing block 10. The sliding square ring 11 is slidably connected to the surface of the fixing square rod 2. Fixing plates 12 are provided horizontally and symmetrically on the inner sidewalls of both ends of the inside of the rocker cylinder 9, and a clamping plate group 13 is movably connected to one end of the fixing plate 12. An inclined plate 14 is provided at one end of the clamping plate group 13. The inclined plates 14 are symmetrically and oppositely arranged on both sides inside the rocker cylinder 9. A feeding hopper 15 is provided at the top of one end of the rocker cylinder 9.

[0023] During operation, the drive motor 4 starts and drives the rotating wheel 5 to rotate. The rocker arm 6 at the top of the rotating wheel 5 pulls the connecting rod 7 under the action of centrifugal force, forcing the U-shaped plate 8 to drag the rocker cylinder 9 to slide horizontally along the fixed square rod 2. The sliding square ring 11 constrains the movement trajectory. The inclined plates 14 symmetrically arranged on both sides inside the rocker cylinder 9 are movably connected to the fixed plate 12 through the clamping plate group 13. When the rocker cylinder 9 moves at different speeds, it swings up and down due to inertia, stirring the tea leaves inside the cylinder to achieve tumbling. The horizontal shaking superimposed on the scattering of the inclined plates 14 forms a two-way motion to enhance the full tumbling of the tea leaves. The flexible connection of the clamping plate group 13 buffers and reduces damage to the leaves.

[0024] Furthermore, the other end of the rocker 9 is provided with an openable cover 16, which is hinged to the rocker 9 and has a sealing strip on the contact surface.

[0025] During operation, the tail end of the rocker drum 9 is hinged to the drum cover 16. When closed, it is locked by a sealing strip, which maintains the humidity environment of the rocker drum 9. The hinged opening and closing enables rapid feeding and discharging of materials.

[0026] Furthermore, the clamping plate group 13 is composed of two parallel elastic metal plates, and the surface of the inclined plate 14 is distributed with hemispherical protrusions.

[0027] During operation, the clamping plate assembly 13 consists of two parallel elastic metal plates, and the surface of the inclined plate 14 is stamped with a hemispherical array of protrusions, allowing the elastic metal plates to absorb high-frequency impacts.

[0028] Furthermore, a needle roller bearing is provided at the movable connection between the rocker arm 6 and the rotating wheel 5, and a self-lubricating bushing is provided at the movable connection between the connecting rod 7 and the U-shaped plate 8.

[0029] During operation, a needle roller bearing is installed at the connection between the rocker arm 6 and the rotating wheel 5, and a self-lubricating bushing is nested at the connection between the connecting rod 7 and the U-shaped plate 8.

[0030] Furthermore, the fixed block 10 and the sliding square ring 11 are fastened together by bolts, and the inner wall of the sliding square ring 11 is fitted with a polyoxymethylene wear-resistant bushing.

[0031] During operation, the fixed block 10 locks the sliding square ring 11 with bolts, and the inner wall of the sliding square ring 11 is bonded with a polyoxymethylene wear-resistant bushing.

[0032] Furthermore, the maximum swing angle of the inclined plate 14 is 30°-45°, and its bottom edge maintains a distance from the inner wall of the rocker 9;

[0033] During operation, the maximum swing angle of the inclined plate 14 is controlled within the acute angle range, and a clearance is reserved between its bottom edge and the inner wall of the rocker 9.

[0034] Working principle: The drive motor 4 rotates the wheel 5, which drives the rocker arm 6 to swing. The rocker cylinder 9 is dragged along the fixed square rod 2 by the connecting rod 7 and the U-shaped plate 8. The sliding square ring 11 is embedded with a wear-resistant bushing for guidance. The inclined plate 14 inside the cylinder is elastically connected by the clamping plate group 13. Under the action of inertia, the hemispherical protrusion of the acute angle swing plate surface moves the tea leaves, forming a two-way turning motion of horizontal shaking and vertical throwing. After the tea leaves are injected into the feeding hopper 15, the cylinder cover 16 can be opened and closed and locked by the sealing strip to maintain humidity. The needle roller bearing of the rocker arm 6 joint and the self-lubricating bushing of the connecting rod 7 reduce transmission friction. The swing gap of the inclined plate 14 avoids scraping the cylinder wall.

[0035] The above are merely preferred embodiments of the present utility model and are 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, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
