Description

Technical Field

[0001] This utility model belongs to the field of rock tea processing technology, specifically relating to an adjustable speed energy-saving shaking machine for rock tea processing. Background Technology

[0002] The shaking machine is a key piece of equipment in the "making green" stage of Wuyi rock tea processing. Its core function is to use mechanical rotation to continuously tumble, collide, and rub the tea leaves inside a bamboo or metal shaking cylinder. This causes gradual and even damage to the cells at the edge of the tea leaves, activating oxidase activity and allowing the tea leaves to undergo moderate enzymatic oxidation. This results in the distinctive "green leaves with red edges" appearance and unique aroma and flavor of Wuyi rock tea. During the shaking process, the tea leaves are subjected to centrifugal force and friction, causing the moisture on the leaf surface to dissipate evenly and the grassy smell to gradually fade. At the same time, aromatic substances are transformed and accumulated, laying an important foundation for the subsequent development of rich floral aroma and mellow rock flavor in Wuyi rock tea. It is a crucial piece of equipment in shaping the quality of Wuyi rock tea.

[0003] The existing rock tea processing shaking machine mainly relies on manual disassembly of the fixed structure between the roller and the cover and opening of the roller cover before and after processing. This results in low material feeding and discharging efficiency, high labor intensity, and frequent manual operation that can delay the process and affect production capacity. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable speed energy-saving shaking machine for processing rock tea, which aims to solve the problems of existing rock tea shaking machines, which rely mainly on manual disassembly of the fixed structure between the roller and the cover and opening the roller cover before and after processing, resulting in low material feeding and discharging efficiency, high labor intensity, and frequent manual operation that can delay the process and affect production capacity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable speed energy-saving shaking machine for processing rock tea, comprising a frame, a control panel mounted on the surface of the frame, a roller mounted on the surface of the frame, a cylinder cover rotatably connected to the open end of the roller via a rotating shaft, a connecting plate connected to the end of the cylinder cover away from the rotating shaft, the surface of the connecting plate being elastically connected to the surface of a fixed plate via a spring, the bottom surface of the fixed plate being connected to the surface of the roller, an arc-shaped limiting plate connected to the surface of the roller, a sliding rod slidably connected to the surface of the arc-shaped limiting plate via an arc groove, the bottom surface of the sliding rod being connected to the cylinder cover, a connecting ear connected to the surface of the cylinder cover, an insert block engaging with the surface of the connecting ear, the insert block slidably connected to the inner wall of a limiting box, a mounting box connected to the surface of the limiting box, a micro motor mounted on the inner wall of the mounting box, a gear connected to the output end of the micro motor, and the gear meshing with a toothed plate on the longitudinal end surface of the other side of the insert block.

[0006] As a preferred embodiment of the adjustable speed energy-saving shaking machine for processing rock tea according to this utility model, the surface of the drum is provided with a fan-shaped opening, the shape and size of which are adapted to the drum cover.

[0007] As a preferred embodiment of the adjustable speed energy-saving shaking machine for processing rock tea according to this utility model, the two sets of arc-shaped limiting plates are respectively located on both sides of the opening end of the drum, and arc-shaped sliding grooves are opened on their surfaces, and the shape and size of the sliding grooves are adapted to the sliding rod.

[0008] As a preferred embodiment of the adjustable speed energy-saving shaking machine for processing rock tea according to this utility model, the upper longitudinal end surface of the insert block is bonded with a threaded rubber sleeve, the shape and size of which are adapted to the rectangular through groove on the surface of the connecting ear.

[0009] As a preferred embodiment of the adjustable speed energy-saving shaking machine for processing rock tea according to this utility model, the surface of the mounting box is connected to the surface of the drum, the surface of the frame is located below the drum and a limiting block is slidably inserted, and the surface of the limiting block is connected to both sides of the receiving box.

[0010] As a preferred embodiment of the adjustable speed energy-saving shaking machine for processing rock tea according to this utility model, the limiting block is an "L"-shaped integrated structure, the shape and size of which are adapted to the sliding grooves symmetrically opened on the surface of the frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] A micro motor mounted on the drum drives the connected gears to rotate, causing the insert block meshing with the gears to move on the limit box, thus disengaging from the locking lugs. This allows the drum cover, which is rotatably connected to the drum, to spring back and open, achieving automatic opening. This reduces labor intensity and increases production efficiency. Furthermore, the rock tea poured from the drum falls directly into the collection box below for collection, improving the efficiency of pouring and collecting, and preventing tea leaves from scattering and wasting during pouring, which would affect the yield of finished rock tea.

[0019] 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 protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides the following technical solution: an adjustable speed energy-saving shaking machine for processing rock tea, including a frame 1, a control panel 2 mounted on the surface of the frame 1, a roller 3 mounted on the surface of the frame 1, a cylinder cover 5 rotatably connected to the open end of the roller 3 via a rotating shaft 4, a connecting plate 6 connected to the end of the cylinder cover 5 away from the rotating shaft 4, the surface of the connecting plate 6 elastically connected to the surface of a fixed plate 8 via a spring 7, the bottom surface of the fixed plate 8 connected to the surface of the roller 3, an arc-shaped limiting plate 9 connected to the surface of the roller 3, an arc-shaped groove on the surface of the arc-shaped limiting plate 9 slidably connecting to a slide rod 10, the bottom surface of the slide rod 10 connected to the cylinder cover 5, and a connecting ear 11 connected to the surface of the cylinder cover 5. 11. The surface of the plug 12 is engaged with the plug block 12. The surface of the plug block 12 is slidably connected to the inner wall of the limiting box 13. The surface of the limiting box 13 is connected to the mounting box 14. The inner wall of the mounting box 14 is equipped with a micro motor 15. The surface of the output end of the micro motor 15 is connected to a gear 16. The surface of the gear 16 is meshed with the toothed plate surface on the longitudinal end surface of the plug block 12 on the other side. In this design scheme, the frame 1, control panel 2, roller 3 and cylinder cover 5 constitute the main body of the shaking machine. The main body of the shaking machine contains a large number of related components. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0021] The main model of the tea shaking machine in this solution is: Model 90 tea shaking machine.

[0022] In use: The main body of the shaking machine drives a 90cm diameter shaking drum 3 (typically 10-30 rpm) via an adjustable speed motor, causing the tea leaves to undergo "water removal" and "fermentation" within the drum 3. When the drum 3 rotates at low speed (e.g., 10-15 rpm), the tea leaves are thrown up and tumbled under the action of gravity and centrifugal force, causing friction damage to the leaf edge cells, promoting the oxidation and polymerization of tea polyphenols, forming the characteristic "green leaves with red edges". When rotating at high speed (e.g., 20-30 rpm), the collision of leaves is strengthened, accelerating the volatilization of grassy aroma and the transformation of aroma substances. By precisely controlling the speed, the optimal shaking force and duration can be matched for different varieties (e.g., Narcissus, Cinnamon) and different tenderness of Wuyi rock tea leaves (e.g., a "light-heavy-light" multi-stage speed change strategy is used for tender leaves), significantly improving the aroma richness and mellow taste of the finished tea. The entire machine is made of lightweight alloy material, with less inertia and a 15% reduction in start-up and shutdown energy consumption. According to actual measurements, the Type 90 shaking machine saves about 1.2 kWh of electricity compared to other models of the same specifications when processing 100 kg of fresh leaves, effectively reducing the processing cost of Wuyi rock tea.

[0023] Preferably, a fan-shaped opening is provided on the surface of the roller 3, the shape and size of which are adapted to the cylinder cover 5.

[0024] In practical use, the cylinder cover 5 is rotated and connected to the open end of the drum 3 to cover the tea leaves inside, making it convenient for loading and unloading.

[0025] Preferably, two sets of arc-shaped limiting plates 9 are located on both sides of the opening end of the roller 3, and arc-shaped grooves are opened on their surfaces, and the shape and size of the grooves are adapted to the slide rod 10.

[0026] In actual use, as the spring 7 rebounds, a set of sliding rods 10 symmetrically distributed on the surface of the cylinder cover 5 slides on the groove opened on the surface of the arc-shaped limiting plate 9, guiding and limiting the rebound of the spring 7.

[0027] Preferably, a threaded rubber sleeve is bonded to the longitudinal end surface of the upper section of the insert 12, and its shape and size are adapted to the rectangular through groove on the surface of the connecting ear 11.

[0028] In practical use, the threaded rubber sleeve on the top of the plug 12 is engaged with the rubber pad on the inner wall of the connecting ear 11, thereby increasing the friction between the two and ensuring the stability of the connection between the connecting ear 11 and the plug 12.

[0029] Preferably, the surface of the mounting box 14 is connected to the surface of the roller 3, the surface of the frame 1 is located below the roller 3 and is slidably inserted into the limiting block 17, and the surface of the limiting block 17 is connected to both sides of the receiving box 18.

[0030] In actual use, after the material is unloaded, pull the handle at the front end of the receiving box 18 to easily pull out the movable limiting block 17 inserted into the frame 1, so as to use the universal wheels at the bottom of the receiving box 18 to transfer the tea leaves in the receiving box 18.

[0031] Preferably, the limiting block 17 is an "L"-shaped integrated structure, and its shape and size are adapted to the symmetrically opened sliding grooves on the surface of the frame 1.

[0032] In practical use, the sliding groove on the frame 1 is used to limit the position of the receiving box 18 that is slidably inserted into the bottom of the frame 1, so as to avoid its position displacement affecting the accuracy of receiving the tea leaves.

[0033] Working principle: When processing rock tea using the frame 1, the power switch connected to the micro motor 15 is turned on, causing it to rotate counterclockwise and drive the connected gear 16 to rotate as well. This causes the toothed plate on the surface of the insert 12, which is meshed with the gear 16, to move downwards within the limiting box 13 via the circular protrusions on both sides, thereby pulling out the insert 12 that is engaged in the connecting ear 11. Consequently, the cylinder cover 5 is driven by the spring 7 connected to its surface to rebound towards the fixed plate 8. At the same time as the spring 7 rebounds, a set of sliding rods 10 symmetrically distributed on the surface of the cylinder cover 5 slides on the sliding grooves opened on the surface of the arc-shaped limiting plate 9, guiding and limiting the rebound of the spring 7. This allows the cylinder cover 5 to be flipped upwards by the rotating shaft 4, exposing the opening end of the previously covered roller 3, so that the tea to be processed can be placed inside the roller 3 for processing. After the tea is fed, the micro motor 15 is turned on to rotate clockwise, thereby driving the connected gear 16 to rotate. As the wheel 16 rotates, the engaging insert 12 slides upward on the limiting box 13, thereby using the part of the threaded rubber sleeve on the top of the insert 12 to engage with the rubber pad on the inner wall of the connecting ear 11, thus increasing the friction between the two and ensuring the stability of the connection between the connecting ear 11 and the insert 12. After processing is completed, the above operation is repeated. When the open end of the roller 3 rotates to a vertical downward position, the micro motor 15 is started again, so that after the cylinder cover 5 is opened, the processed tea leaves in the roller 3 are poured into the receiving box 18 below. The receiving box 18 is located directly below the roller 3, and its opening width is larger than that of the roller 3, so that the processed tea leaves can fall completely into the receiving box 18 below and be collected. After the material is unloaded, the handle at the front end of the receiving box 18 is pulled to easily pull out the limiting block 17 that is movably inserted into the frame 1, thereby using the universal wheels at the bottom of the receiving box 18 to transfer the tea leaves in the receiving box 18.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
