Strip groove A where the grinding unit slot 45 is parallel to it on rear side of abrasive areas A37 rotation direction.

The inner wall of the casing 1, corresponding to lower millstone 6 bottom surface be equipped with multiple supporting plates 21, the supporting plate 21 is with lower millstone 6 Axle center centered on, be uniformly distributed in the inner wall of casing 1.

Annular retaining ring B22, the annular retaining ring are equipped on the bottom surface of the casing 1, by the center of circle of the axle center of transmission shaft A14 The outer diameter of B22 is less than the internal diameter of supporting plate 21, and the discharge port 23 is set to the bottom surface of casing 1, positioned at the outside of annular retaining ring B22 position Set place.

The side wall of the axle sleeve 19 is fixed with scraper plate 24, the bottom of the scraper plate 24 be located at annular retaining ring B22 and casing 1 The bottom of casing 1 between side wall contacts.

The notch of the feed well 3 is connected with cover board 33, and the side of the cover board 33 passes through hinge 34 and feed well 3 Connection.

The feed inlet 8 is the up big and down small bucket-shaped structure in aperture.

The suitable for reading of the feed inlet 8 is equipped with backgauge film 35, the matching suitable for reading of the backgauge film 35 and feed inlet 8, and keeps off Material film 35 is successively spliced by multiple fan-shaped film valves.

When the present invention uses, the tealeaves of drying is put into feed well 3, then tealeaves is pressed down on to tealeaves and is worn Backgauge film 35 is crossed to enter in casing 1 and fall into screen tube 4.

Then start driving motor 15, it is broken to become tealeaves after the particle of particle cutter for the tealeaves in screen tube 4; Although screen tube 4 is connect by bearing A31 with shaft A9, bearing A31 can still generate the frictional force of very little, to make shaft A9 drives screen tube 4 to rotate;And tealeaves is broken, leaves screen tube by mesh 12 under the centrifugal force and gravity of screen tube 4 4。

During the particle of tealeaves, certain tealeaves that do not smash completely in screen tube 4 are broken may be by screen tube 4 The mesh 12 of inner wall is blocked, and scraping rod 13 is then struck off the tealeaves for blocking mesh 12 in screen tube 4 is broken or is brushed during rotation It removes, it can be normal through mesh 12 to guarantee that tealeaves is broken.

Leave the broken edge that can be fallen in upper millstone 5 of tealeaves of screen tube 4, on even annular retaining ring A27;Due to annular Slope surface B28 set by retaining ring A27 directly slides to the top surface of upper millstone 5 so that tealeaves on annular retaining ring A27 is broken;Due to Upper millstone 5 is equally connect by bearing A31 with shaft A9, so the also slowly rotation of upper millstone 5, with upper millstone 5 Rotation, tealeaves on upper millstone 5 is broken to enter recess portion 30, subsequently into material guide hole 41 along deflector chute 38, hence into upper mill It is ground between disk 5 and lower millstone 6.

Since lower millstone 6 is driven by axle sleeve 19 and driving motor 15, so in driving wheel C25 and driving wheel D26 Gear ratio under, 6 slow rotation of lower millstone;Since upper millstone 5 is slowly rotated by bearing A31 and shaft A9 rotation connection, And the rotation direction of axle sleeve 19 is identical more than shaft A9, so the relative rotation speed between upper millstone 5 and lower millstone 6 is slower;Tealeaves After the broken grinding by between upper millstone 5 and lower millstone 6 forms tea powder, falls and be located on the outside of annular retaining ring B22 in casing 1 On bottom surface, the tea powder that then scraper plate 24 is will fall off under the action of axle sleeve 19 on 1 bottom surface of casing is scraped, and is scraped to discharge port When at 23 positions, tea powder is fallen in charge cask 7.

When will fill in charge cask 7, driving motor 15 is closed, and by charge cask 7 out of charge notch It takes out.
