Description

Technical Field

This scheme can screen tea leaves by rotating the screen barrel and the screen tube, thereby realizing automatic screening of tea leaves and no vibration is generated during the screening process, thereby causing a series of adverse effects.

[0003] However, the above scheme still has some shortcomings. For example, when the sieve barrel and the sieve tube are sieving tea leaves, since the sieve holes of the sieve barrel and the sieve tube are relatively small, some tea residues are easily stuck in the sieve holes when sieving tea leaves, causing the sieve holes to be blocked. The above scheme does not have a device for cleaning the sieve holes, so the sieve holes need to be cleaned manually and regularly, which increases the labor force and makes the cleaning complicated. In view of this, the utility model proposes an integrated tea screening device. Utility Model Content

[0026] like Figure 3 As shown, the cleaning mechanism 2 also includes a third fixed frame 24, which is fixedly connected above the two first fixed frames 21, and the top of the third fixed frame 24 is rotatably connected to two bidirectional screw rods 25, one end of the two bidirectional screw rods 25 are fixed on one side of the third fixed frame 24, and are transmission-connected with a transmission belt 26, and the two bidirectional screw rods 25 are respectively threadedly connected to the first moving block 27 and the second moving block 28, one end of one of the bidirectional screw rods 25 is fixedly connected to a fixed block 212 and a gear 210, and the lower part of the fixed block 212 is fixedly connected to the upper part of one of the support frames 11, and a gear ring 211 is meshed at the lower part of the gear 210, and the gear ring 211 is fixedly connected to the outside of the screening mechanism 3.

[0027] When the second screening cylinder 32 rotates, the gear ring 211 and the gear 210 are driven to rotate, thereby driving the two bidirectional screws 25, so that the two moving blocks move back and forth, and drive the brush 29 to brush back and forth on the surface of the first screening cylinder 31 and the second screening cylinder 32. Since the first screening cylinder 31 and the second screening cylinder 32 are also rotating, all the screening holes 33 can be cleaned to prevent tea leaves or tea debris from clogging the screening holes 33.
