Description

Technical Field

[0001] The present invention relates to the field of tea processing, and particularly to a tea withering machine with adjustable storage area. Background Art

[0002] Withering is the most crucial process for the formation of oolong tea quality, and the withering machine is an important tool for the mechanization of oolong tea processing.

[0003] Currently, withering machines are mainly divided into two categories: vibration type and shaking cage type. The vibration type withering machine can be divided into single sieve and vibration trough. The single sieve vibration type withering machine requires manual assistance for upper and lower leaves, and has low withering efficiency, which is not convenient for continuous production; although the vibration trough type withering machine is convenient for continuous processing, the withering effect is poor, and when ensuring the withering intensity, the vibration time is long and the vibration noise is large. The shaking cage type has two types: drum continuous type and single cage type. The drum type withering machine is convenient for continuous production, but the withering time is uncontrollable; the single cage type withering machine produces the best quality tea, and this type of equipment is mostly used in current tea processing.

[0004] When the existing shaking cage type withering machine is in use, a single cavity is mostly arranged inside the shaking cage, which cannot process two different qualities of tea simultaneously, has low flexibility, and increases the idle space of the equipment.

[0024] An installation block 11 is fixed on the sliding shaft 8. Two closing plates 12 are movably arranged on the installation block 11. A force transmission rod 13 is arranged between the closing plate 12 and the adjusting seat 10. One end of the force transmission rod 13 is movably connected to the closing plate 12 through a pin shaft, and the other end of the force transmission rod 13 is movably connected to the adjusting seat 10 through a pin shaft.

A first transmission gear 23 is mounted on the first rotating shaft 22. The first transmission gear 23 meshes with the first transmission gear ring 21. The first rotating shaft 22 uses a motor as the power source. Under the action of the first transmission gear 23 and the first transmission gear ring 21, the two withering cages can be respectively rotated on the machine frame 1 through two motors.

[0026] The bottom of the feed hopper 7 is communicated with the first feed pipe 6 through a rectangular pipe 24. A first air inlet pipe 25 is communicated and arranged on one side of the first feed pipe 6. An installation shaft 26 is movably arranged inside the rectangular pipe 24. Two blanking plates 27 are symmetrically fixed on the installation shaft 26. One end of the installation shaft 26 extends out of the rectangular pipe 24 and is provided with a transmission worm gear 28. A transmission worm 29 is meshed on one side of the transmission worm gear 28. A first bevel gear 30 is mounted on the transmission worm 28. A second rotating shaft 31 is movably arranged on one side of the rectangular pipe 24. A second bevel gear 32 is mounted on the second rotating shaft 31. The second bevel gear 32 meshes with the first bevel gear 30. A second transmission gear 33 is mounted on the second rotating shaft 31. A second transmission gear ring 34 is mounted on the mounting bracket 4. The second transmission gear ring 34 meshes with the second transmission gear 33. When the first withering cage 2 and the mounting bracket 4 rotate, they will drive the second transmission gear ring 34 to rotate. Under the transmission action of the second transmission gear ring 34 and the second transmission gear 33, the second rotating shaft 31 will be driven to rotate. Finally, under the action of the two bevel gears, the transmission worm 29 and the transmission worm gear 28, the installation shaft 26 will be driven to rotate. When the installation shaft 26 drives the blanking plate 27 to rotate, the blanking speed of the tea leaves can be increased.

[0027] The blanking mechanism includes a second feed pipe 35, a second air inlet pipe 36, a blanking cylinder 37, and a material guiding pipe 38. A side pipe 39 is installed on one side of the frame 1. The side pipe 39 is communicated with the first withering cage 2. A blanking cylinder 37 is arranged at the side pipe 39. The output end of the blanking cylinder 37 extends into the side pipe 39 and is fixed with a blocking plate 41. When it is necessary to blank into the second withering cage 3, start the cylinder 37 to drive the blocking plate 41 to move away from the first withering cage 2.

[0028] A second feed pipe 35 is installed on one side of the frame 1. The second feed pipe 35 is communicated with the second withering cage 3. The second feed pipe 35 and the side pipe 39 are communicated through a material guiding pipe 38. A second air inlet pipe 36 is communicated and arranged at the center of the second feed pipe 35. A number of spiral guide vanes 40 are arranged inside both the first withering cage 2 and the second withering cage 3. When the spiral guide vanes are arranged on the inner wall of the withering cage and the material is discharged from the right end, the guide vanes 40 are arranged in a clockwise spiral along the axial direction of the drum. During the rotation process, the tea leaves are affected by the centrifugal force and spiral down along the guide vanes and finally are discharged from the discharge end. The angle between the guide vane and the cylinder wall is usually 30°-45°, which can not only ensure the uniform turning of the tea leaves but also form a one-way channel towards the discharge end.

[0029] The working principle of the present invention: When this withering machine is in use, the staff can place the tea leaves to be withered in different areas inside the first withering cage 2 according to the different qualities of the tea leaves to be withered. The two areas inside the first withering cage 2 are separated by two closing plates 12. The tea leaves located between the side pipe 39 and the closing plate 12 are those with a shorter withering time requirement. When the tea leaves near the side pipe 39 are initially withered, the staff can open the blanking cylinder 37. Under the action of the spiral guide vanes 40 and the wind force at the second air inlet pipe 36, the tea leaves will enter the second withering cage 3 for further withering and discharging. And when all the tea leaves in this area fall into the second withering cage 3, at this time, the electric telescopic rod 18 is started to drive the cross bar 14 to move. Under the action of the cross bar 14, the adjusting seat 10 will be driven to move along the through groove 9. Under the action of the adjusting seat 10 and the force transmission rod 13, the closing plate 12 is opened. At this time, the tea leaves in the other area will enter the area near the side pipe 39 under the action of the spiral guide vanes 40 and the wind force at the first air inlet pipe 25. When the tea leaves are completely transferred, the closing plate 12 is closed. At this time, the tea leaves with a shorter withering time requirement can be continuously added to the feed hopper 7 through the material hoist (it is necessary to ensure that the remaining withering time of the tea leaves with a longer withering time is less than that of the tea leaves with a shorter withering time according to the actual situation, otherwise the addition of materials can be postponed). According to the quantity of the added materials, the staff can adjust the position of the closing plate 12 inside the first withering cage 1. Only need to close the two closing plates 12 (to avoid contact between the closing plate 12 and the guide vane plate 40 when the closing plate 12 moves), then rotate the crank 20 to drive the threaded rod 19 to rotate. Under the action of the threaded rod 19, the moving seat 17 will move along the sliding groove 16, thereby driving the entire sliding shaft 8 and the closing plate 12 above it to move inside the first withering cage 2, achieving the purpose of easily adjusting the position of the closing plate 12 and further improving the flexibility of the device; During the feeding process, in order to avoid blockage of the tea leaves, under the action of the second transmission gear 33, the second transmission ring gear 34, the two bevel gears, the transmission worm 29 and the transmission worm wheel 28, the mounting shaft 26 will be driven to rotate. When the mounting shaft 26 drives the blanking plate 27 to rotate, the blanking speed of the tea leaves can be increased; When the quality of the put-in tea is single, set the blocking plate 41 to be normally open and open the closing plate 12, then this withering machine can be used as a traditional withering device.
