The surfaces of the inner rotating plate 13, the outer rotating plate 14 and the shovel plate 32 are all provided with a plurality of water filtering holes 31 in a penetrating way.

When using this sealwort extract preparation facilities, at first carry upright bucket 6 with hot water through inlet tube 11 in, starter motor 22 after that, motor 22 drives reducing gear box 23 and rotates, and the output of reducing gear box 23 drives card post 19 and rotates, and card post 19 and pivot 18 at this moment pass through draw-in groove 8 joint, and pivot 18 rotates and drives crushing board 17 and rotate after that, and crushing board 17 drives rotary barrel 16 simultaneously and rotates, and rotary barrel 16 drives outward and revolves board 14 and interior whirl board 13 and rotates.

Then sealwort is added into a crushing barrel 1 of a box through a feed hopper 7, the sealwort slides onto a crushing plate 17 along one surface of an extrusion plate 2 and slides between the extrusion plate 2 and the crushing plate 17 through a conical surface of the crushing plate 17, a spiral convex ring 27 is driven to rotate through the rotation of the crushing plate 17, the outer diameter of the sealwort crushing plate 17 is conveyed through the rotation of the spiral convex ring 27, the distance between the crushing plate 17 and the extrusion plate 2 is reduced in the conveying process, the distance between a crushing tooth 26 and the spiral convex ring 27 is also reduced, the sealwort is extruded and ground through the crushing tooth 26 and the crushing plate 17 and then falls into a vertical barrel 6 through a guide barrel 15, crushed sealwort is gradually screwed into the bottom of the vertical barrel 6 under the rotating action of an outer rotary plate 14, the crushed sealwort falls under a rotary barrel 16 through the inclined surface guidance of the bottom surface of the vertical barrel 6, meanwhile, a shovel plate 32 shovels the sealwort by rotating, conveys the sealwort to an inner rotary plate 13, the sealwort rises through an inner rotary plate 13, when the sealwort is separated from the water surface, the sealwort falls into a water draining cylinder 12, the water draining cylinder 12 continuously flows into a water draining cylinder 12, and then the water draining cylinder 12 continuously flows upwards, the water draining cylinder 3, and the water draining cylinder 12 continuously flows upwards, and the water draining cylinder 12.

When the sealwort between crushing board 17 and stripper plate 2 is crowded into too much, crushing board 17 moves down, drives pivot 18 simultaneously and moves down, and fixed plate 21 compresses pressure spring 20 downwards, and card post 19 slides in draw-in groove 8, when crushing board 17 removes, drives rotary barrel 16 and moves down, and rotary barrel 16 drives outward rotating plate 14 and interior rotating plate 13 simultaneously and removes, and deformation takes place for shovel board 32 under the pressure of interior rotating plate 13, and swivel 29 slides in recess 30 simultaneously.

When the crushing plate 17 moves down, the sealwort at the edge of the crushing plate 17 can be crushed incompletely because of the increase of the distance between the crushing plate 17 and the extrusion plate 2, under the rotation of the crushing plate 17, the massive sealwort is pushed to the edge of the crushing plate 17 to be contacted with the crushing knife 25 and is cut into small particles, and then the crushing of the excessive sealwort of the crushing plate 17 and the extrusion plate 2 is carried out, the pressure spring 20 upwards pushes the fixed plate 21, the fixed plate 21 drives the crushing plate 17 to move upwards through the rotating shaft 18, the crushing plate 17 returns to the original position, the crushing plate 17 drives the rotary barrel 16 to reset, meanwhile, the shovel plate 32 is contacted with the bottom wall of the vertical barrel 6 all the time because of the elastic effect of the shovel plate 32.

Move down and the in-process that resets under revolving barrel 16, outward revolve board 14 and interior spiral board 13 respectively to the sealwort above that downwards with the upwards propelling movement, play the effect of stirring to the sealwort in opposition bucket 6, simultaneously, the drainage hole 31 that interior spiral board 13, outer spiral board 14 and shovel board 32 surface were seted up makes things convenient for the passing through of rivers for the sealwort is broken up, and is more abundant with the contact of water, and the transport of sealwort upwards is revolved to interior spiral board 13 more convenient simultaneously.

When the sealwort passes through the water inlet on the inner rotating plate 13, the water pressure in the water inlet pipe 11 is increased and keeps a certain positive pressure, water flows downwards through the inner rotating plate 13, then flows upwards along the outer rotating plate 14 again through the bottom end of the rotating barrel 16, the reverse sealwort is washed in the process, and then the water flows out of the water outlet pipe 4 to take away polysaccharide substances extracted from the sealwort.

When the outward rotating plate 14 and the inward rotating plate 13 rotate, the crushed sealwort on the surface of the screen 5 can be scraped, and the screen 5 is prevented from being blocked.

In summary, the sealwort extract preparation apparatus, which is provided with the water filtering holes 31 on the surfaces of the outer rotating plate 14 and the inner rotating plate 13 to facilitate the passage of water flow, is provided with the pressure spring 20, the rotating shaft 18 can move up and down and can drive the outer rotating plate 14 and the inner rotating plate 13 to move up and down at the same time, and can respectively push the sealwort on the surfaces of the sealwort while moving, so that the sealwort is in contact with water more sufficiently, the extraction effect is better, the residence time of the sealwort in the vertical barrel 6 can be prolonged by the reverse spiral design of the outer rotating plate 14 and the inner rotating plate 13, the water flow direction is opposite to the movement direction of the sealwort by the arrangement of the water inlet pipe 11 and the water outlet pipe 4, the discharged sealwort is always in contact with unsaturated water, the situation that the sealwort extract is dissolved and saturated in water and is not wasted when the sealwort extract is not extracted any more, and the extraction of sealwort is more sufficient is achieved.
