Description

Technical Field

[0001] The invention relates to the field of tea processing equipment, in particular to a tea leaf shaking machine. Background Art

[0002] Shaking the green leaves is also an important step in the initial processing of green oolong tea. Its purpose is to subject the green leaves to mechanical forces, damage part of the leaf edge cell tissue, promote the oxidation, polymerization and condensation of polyphenol compounds, produce colored substances and promote the formation of aromatic compounds.

[0003] At present, except for a small amount of precious tea, the shaking of green tea has basically been mechanized. The commonly used shaking machines in the existing technology include two categories: The first category has the application number: 200710009912.5, and the patent name is: Water Screen Tea Shaker, which provides a single water screen, which can process a small amount of tea. Compared with manual work, it does improve production efficiency, but the overall improvement is not much. On this basis, there are also tea shakers in the prior art that stack several water screens up and down and drive multiple water screens to work synchronously. Although it further improves the single production efficiency, the workers' loading and unloading operations are more cumbersome, and there is no obstruction on the outside of the water screen, which is destined to limit the amount of tea that can be processed at a single time.

[0004] The other type has application number: 201610582205.4, and the patent name is: A tea leaf shaking machine. This type of drum-type tea leaf shaking machine can shake a large amount of tea leaves simultaneously with one filling, but the disadvantage is that after the tea leaves are shaken, they need to be spread on the water screen again to dry, and all subsequent operations are done manually by workers, and the degree of automation is insufficient.

[0005] In order to further improve the automation and mechanization of tea shaking operations and subsequent processes, upgrades and modifications are carried out based on the drum-type tea shaking machine, thereby further improving the mechanization level of tea processing and high tea production efficiency.

[0008] In order to realize the mechanized drive of the U-shaped frame, the support frame includes a base plate, a vertical support arm is provided on the base plate, a second motor is fixed to the upper end of the support arm, the second motor is a stepping motor, and the output shaft of the second motor is fixed in the middle position of the U-shaped frame.

[0009] In order to realize the equidistant extension and retraction of the U-shaped frame, the bottom rod of the U-shaped frame includes a rectangular tube, and a support rod is slidably installed at each end of the rectangular tube. The two support rods are respectively provided with electric cylinders for driving them to extend and retract synchronously.

[0010] In order to achieve the sliding and fitting installation of the telescopic unit, the two arc-shaped plates in the telescopic unit are slidably connected via a sliding groove and a sliding rail.

[0011] In order to realize the opening and closing of the two semicircular plates, a plurality of fixing blocks are arranged at intervals on the non-hinged side of the two semicircular plates. The fixing blocks are installed on the outermost arc-shaped plate of the two arc-shaped plates of the telescopic unit. Bolts are screwed on the fixing blocks installed on the semicircular plate on which the baffle is fixed, and threaded holes matching the bolts are provided on the fixing blocks on the other semicircular plate.

[0012] In order to facilitate the opening of the semicircular plate, a telescopic handle is provided on the semicircular plate without the baffle installed, and the telescopic handle is fixed on a plurality of fixing blocks.

[0013] In order to realize the driving of the first motor, a first rotating shaft coaxial with the green shaking cylinder is fixed at one end, and the free end of the first rotating shaft passes through the side wall of the U-shaped frame.

When the axis of the tea-shaking cylinder is vertical, the tea-shaking cylinder retracts to the shortest state. In this state, the intervals between the water screens in the tea-shaking cylinder are small, and workers can take out the water screens individually or as a whole within a small range for racking, which simplifies the operation and is not prone to tipping.

[0018] 3. The present invention also provides a shaking method, in which the internal space of the shaking tube is changed by continuous extension and retraction of the shaking tube during the shaking process, so that the tea leaves roll more evenly in the shaking tube, thereby further improving the efficiency and quality of shaking.

A U-shaped frame 2 is rotatably mounted on the support frame 1, and the bottom rod of the U-shaped frame 2 is retractable, and the output shaft of the second motor 10 is fixed at the middle position of the U-shaped frame 2. The bottom rod of the U-shaped frame 2 includes a rectangular tube, and a support rod is slidably mounted at each end of the rectangular tube, and the two support rods are respectively provided with electric cylinders that drive them to synchronously retract.

[0027] A shaking cylinder is rotatably mounted on the U-shaped frame 2. The shaking cylinder is densely covered with through holes. The shaking cylinder includes two semicircular plates 3. The two semicircular plates 3 are hinged and can be buckled into a cylinder. The semicircular plates 3 include multiple telescopic units. Each telescopic unit includes two coaxial arc plates 4 that are slidably connected. The two arc plates 4 in the telescopic unit are slidably connected through a slide groove and a slide rail 11. Multiple telescopic units are fixedly connected at the first position, and a baffle 5 is fixed at each end of one semicircular plate 3. Multiple fixed blocks 12 are arranged at intervals on the non-hinged side of the two semicircular plates 3. The fixed blocks 12 are installed on the outer arc plates 4 of the two arc plates 4 of the telescopic unit. Bolts 13 are screwed on the fixed blocks 12 installed on the semicircular plate 3 fixed with the baffle 5, and threaded holes matching the bolts 13 are arranged on the fixed blocks 12 on the other semicircular plate 3. A telescopic handle 14 is arranged on the semicircular plate 3 without the baffle 5, and the telescopic handle 14 is fixed on multiple fixed blocks 12.

[0028] The inner side of the semicircular plate 3 is evenly spaced with a plurality of semi-circular slots 6 at intervals from top to bottom. The positions of the slots 6 on the two semi-circular shapes correspond to each other. A water screen 7 is detachably installed in the slots 6. A first motor 8 is fixed to one end of the U-shaped frame 2. When the axis of the green-shaking cylinder is horizontal, the first motor 8 drives the green-shaking cylinder to rotate. A first rotating shaft coaxial with the green-shaking cylinder is fixed to one end of the green-shaking cylinder. The free end of the first rotating shaft passes through the side wall of the U-shaped frame 2. The first rotating shaft and the side wall of the U-shaped frame 2 can rotate relative to each other and can slide relative to each other. A gear 15 is fixed to the end of the first rotating shaft. The first motor 8 is fixed to the side wall of the U-shaped frame 2. A gear shaft 16 meshing with the first gear 15 is fixed to the first motor 8.

[0029] A vibration motor 9 is fixed to the other end of the U-shaped frame 2, which drives the shaking cylinder to vibrate when the axis of the shaking cylinder is vertical. A second rotating shaft coaxial with the shaking cylinder is rotatably installed at the other end of the shaking cylinder, and the free end of the second rotating shaft penetrates the side wall of the U-shaped frame 2 on the corresponding side. The second rotating shaft and the side wall of the U-shaped frame 2 can only slide relative to each other, and cannot rotate relative to each other. The vibration motor 9 is fixed to the free end of the second rotating shaft. The first rotating shaft and the second rotating shaft between the shaking cylinder and the U-shaped frame 2 are respectively equipped with a spring 17.

[0030] Working principle and use method of the present invention: The use of the present invention is to first drive the U-shaped frame 2 to drive the shaking tube to rotate to the horizontal state of the axis through the second motor 10, and control the extension of the electric cylinder so that the entire shaking tube is extended to the limit position. The auxiliary rotation of the shaking tube makes the telescopic handle 14 of the waist pain be placed in the upper front position. In this state, the bolt 13 is screwed to separate it from the bolt 13 hole on the fixed block 12 to achieve the purpose of opening the semicircular plate 3 without the baffle 5. At this time, multiple water screens 7 are placed in the corresponding slots 6 in turn, and the tea leaves to be processed are evenly added to the space divided by the water screen 7. After completion, the two semicircular plates 3 are fixed by screwing the bolts 13 to close the shaking tube.

[0031] During the shaking process, the rotating motor is turned off, and the first motor 8 is turned on. The first motor 8 drives the gear shaft 16 to engage the gear 15 to realize the rotation of the shaking cylinder. In this process, the U-shaped frame 2 can be fixed and the electric cylinder on the U-shaped frame 2 can be driven to reciprocate and expand. In the process of the electric cylinder reciprocating and driving the U-shaped frame 2 to expand and contract, the space in the shaking cylinder is continuously enlarged and reduced, and the tea leaves inside gradually produce different motion trajectories in the process of space change during the shaking process, under which the efficiency and quality of the tea shaking are improved.

[0032] After the shaking operation is completed, the first motor 8 is turned off, and the second motor 10 is turned on. Under the drive of the second motor 10, the shaking cylinder with a horizontal axis is rotated to a vertical axis state. In this state, the vibration motor 9 is turned on, and the shaken tea leaves are evenly spread on the water screen 7 under the action of the vibration motor 9. After completion, the U-shaped frame 2 is controlled to retract, and after completion, the bolts 13 are screwed to open the semicircular plate 3 without the baffle 5, so that the space between the two semicircular plates 3 is fully opened. At this time, multiple water screens 7 are taken out individually or as a whole through manual or mechanized taking-out equipment and placed on the drying rack.

[0033] In order to further improve the level of automation, the multiple water screens 7 can be operated in sequence in coordination with the loading and unloading brackets of the grabbers. At this time, when loading, the multiple water screens 7 of the drying rack can be directly mechanized and filled as a whole in the state where the axis of the shaking tube is vertical, further improving the mechanization and automation efficiency. The present invention provides a new idea, device and method for fully realizing automation.
