[0002] During the production, transportation and storage of tea, it is easy to be contaminated by dust, soil, foreign matter, etc., which affects the quality of tea. The tea winnowing machine is a device that uses wind power to separate impurities from tea. It uses atmospheric airflow to separate tea leaves and impurities through a screening net. After the tea leaves are winnowed by the machine, their appearance becomes cleaner and neater, and their taste becomes smoother and more delicious, which can better meet the quality requirements of consumers, thereby increasing the commercial value of tea.

[0003] When pouring tea leaves into a conventional tea wind sorting machine for screening, a large amount of tea leaves fall in piles, are easily mixed together, and are unevenly dispersed, which results in incomplete screening of the tea leaves during wind sorting, resulting in poor screening effect.

[0004] Therefore, a tea leaf winnowing machine is proposed. Utility Model Content

[0025] The intermittent structure includes a fixed inclined plate 6, which is mounted on the inner wall of the feed pipe 2. A rotating hole 62 is provided on one side of the feed pipe 2. A movable inclined plate 61 is rotatably mounted on the inner wall of the feed pipe 2 and the rotating hole 62. A driving plate 63 is mounted on the movable inclined plate 61. A cam 64 is provided at the bottom of the driving plate 63. The cam 64 contacts the driving plate 63. A connecting rod 65 is installed on the cam 64. A limit plate 66 is rotatably mounted on the connecting rod 65. A support plate 67 is installed at the bottom of the limit plate 66. The support plate 67 is mounted on the feed pipe 2. A rotating shaft 69 is installed on the inner wall of the feed pipe 2. A fixed inclined plate 61 is provided on the movable inclined plate 61. The rotating shaft 69 is rotatably mounted in the fixing hole 611, and a torsion spring 610 is sleeved on the rotating shaft 69. One end of the torsion spring 610 is mounted on the rotating shaft 69, and the other end of the torsion spring 610 is mounted on the inner wall of the fixing hole 611. The linkage structure includes a worm wheel 7, which is mounted on the connecting rod 65. A worm 71 is meshingly mounted on the worm wheel 7. A transmission assembly 72 is mounted on the spiral feeding rod 11. The transmission assembly 72 is rotatably mounted on the support plate 67, and the worm 71 is mounted on the transmission assembly 72. Pour the tea leaves into the upper hopper 3 in advance, and the tea leaves will be blocked by the fixed inclined plate 6 and the movable inclined plate 61 and will not fall. Start the motor 10, the motor 10 rotates to drive the spiral feeding rod 11 to rotate, the spiral feeding rod 11 rotates to drive the transmission assembly 72 to rotate, the transmission assembly 72 rotates to drive the worm 71 to rotate, the worm 71 rotates to drive the worm wheel 7 to rotate, the worm wheel 7 rotates to drive the cam 64 to rotate, when the cam 64 rotates until its convex end contacts the driving plate 63, it will lift the driving plate 63, at this time, it will drive the movable inclined plate 61 to rotate downward and cause the torsion spring 610 to deform, thereby creating a gap between the fixed inclined plate 6 and the movable inclined plate 61, and a part of the tea will fall into the feeding pipe 2 through the gap. When the cam 64 is not in contact with the driving plate 63 When touched, the torsion spring 610 rebounds and drives the movable inclined plate 61 to rotate back to its original position to block the bottom of the tea leaves again, thereby preventing the tea leaves from falling in piles, resulting in uneven dispersion and inability to be uniformly screened later. The tea leaves falling into the feed pipe 2 are air-selected by the fan 13, and the impurities inside the tea leaves are screened through the filter net 12 and collected in the collection box 14. The remaining tea leaves will continue to fall downward until they slide into the feed pipe 4, and be spirally fed to the top by the spiral feeding rod 11, until they slide into the feed pipe 2 from the inclined tube 5, and continue to be air-selected by the fan 13, thereby enabling the tea leaves to be air-selected more thoroughly and with better results.

After the tea leaves are air-selected, the fan 13 is turned off, the threaded rod 83 is unscrewed from the sealing door 8, the restriction on the sealing door 8 is lost, and the sealing door 8 is rotated inward until its bottom is on the overlapping block 84, thereby intercepting the tea leaves dropped by the spiral feeding rod 11, and the tea leaves can be taken out from the feeding port 85. After the taking out is completed, the sealing door 8 is rotated again to block the feeding port 85, and the threaded rod 83 is screwed into the sealing door 8, so that the sealing door 8 can be fixed to improve the sealing performance during subsequent screening.

The stopper 68 can prevent the movable inclined plate 61 from rotating too much under the elastic force of the torsion spring 610. When the movable inclined plate 61 is not opened, the bottom of the upper hopper 3 is always blocked to prevent the tea from leaking out.

[0028] The working principle is as follows: when the tea leaves are winnowed, the tea leaves are first poured into the upper hopper 3, and the tea leaves will be blocked by the fixed inclined plate 6 and the movable inclined plate 61 and will not fall down. Then the motor 10 is started, and the rotation of the motor 10 drives the spiral feeding rod 11 to rotate, and the rotation of the spiral feeding rod 11 drives the transmission assembly 72 to rotate, and the rotation of the transmission assembly 72 drives the worm 71 to rotate, and the rotation of the worm 71 drives the worm gear 7 to rotate, and the rotation of the worm gear 7 drives the cam 64 to rotate through the connecting rod 65. When the cam 64 rotates until its convex end contacts the driving plate 63, the driving plate 63 will be lifted up, and at this time, the movable inclined plate 61 will be driven to rotate downward and the torsion spring 610 will be deformed, thereby a gap will be generated between the fixed inclined plate 6 and the movable inclined plate 61, and a part of the tea leaves will fall into the feeding pipe 2 through the gap, and when the cam 64 is no longer in contact with the driving plate 63, the rebound of the torsion spring 610 will drive the movable inclined plate 61 to rotate back to its original shape. The bottom of the tea leaves will be blocked again in the position, thereby preventing the tea leaves from falling in piles, resulting in uneven dispersion and inability to be uniformly screened later. The tea leaves falling into the feed pipe 2 will be air-selected by the fan 13, and the impurities inside the tea leaves will be screened through the filter screen 12 and collected in the collection box 14. The remaining tea leaves will continue to fall downward until they slide into the feed pipe 4, and be spirally fed to the top by the spiral feed rod 11, until they slide into the feed pipe 2 from the inclined tube 5, and continue to be air-selected by the fan 13, thereby enabling the tea leaves to be air-selected more thoroughly and with better effect. After the tea leaves are air-selected, the fan 13 is turned off, the threaded rod 83 is unscrewed from the sealing door 8, the restriction on the sealing door 8 is lost, and the sealing door 8 is rotated inward until its bottom is placed on the overlapping block 84, thereby the tea leaves dropped by the spiral feeding rod 11 can be intercepted, and the tea leaves can be taken out from the feeding port 85.
