The stone mill of automatic control charging
Technical field
The invention belongs to food processing machinery field, relate to a kind of stone mill, specifically a kind of stone mill that automatically can control charging rate.
Background technology
The stone mill of current use, the switch of charging flashboard and the size of charging rate are all Artificial Control, when needs stone mill works, manually charging flashboard must be first opened before running, and then starter motor or other power drive stone mill running, in the meantime, existing exceed required raw material when stone mill runs well and enter in wear eye, this is stone mill one of reason of " drawing thick " when just starting running; When stone mill need be stopped to work, first must stop and drive the power of stone mill running, then manually close charging flashboard again, in the meantime, some exceedes required raw material when stone mill runs well and enters in wear eye again, and this is also that stone mill " draws " when just starting running one of reason thick; In addition also because stone mill running speed is slow, it is large that charging flashboard gap is opened, and charging rate soon " drawing thick ", so just must first stop stone mill operating, more manually turn flashboard gap down; Particularly when stone mill rotating unevenness, the more difficult control of charging flashboard.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of stone mill that automatically can control charging flashboard switch and charging rate.
The technical solution used in the present invention is: this controls the stone mill of charging automatically, comprise mill frame, mill, engine, lower fan abrasive disc, upper fan abrasive disc, hopper and automatically control feed arrangement, it is characterized in that: under mill frame, engine is housed, mill frame there is mill, mill there is lower fan abrasive disc, lower fan abrasive disc has upper fan abrasive disc, upper fan abrasive disc elevating hopper, hopper is equipped with along place and automatically controls feed arrangement.
Above-described automatic feeder, is characterized in that: hang a fork on the upper edge of hopper, fork bottom hangs with pendulum, and middle part is connected with charging activity flashboard.
Above-described fork, is characterized in that: hanging over hopper has screw adjustable up and down along the fork top located, and the pendulum that bottom hangs is the pouring weight that multi-disc can fold extension.
Above-described charging flashboard, it is characterized in that: this charging flashboard is made up of upper and lower two shoe brake plates, upper flashboard is fixed on the cone bottom of hopper, there is horizontal elongated hole centre, this horizontal elongated hole can be overlapped into feed-throughs with the hole of growing crosswise of movable flashboard centre below, also controlled charging hole can be partly overlapped into, also can non-overlapping copies, become the blind hole of closing charging; Lower flashboard right-hand member is flexibly connected with in the middle part of fork.
After adopting above technical scheme, due to the centrifugal force of pendulum during the running of this stone mill, can automatically pull open charging flashboard, when this stone mill shuts down, automatically can close flashboard, this stone mill and automatically can strengthen inlet amount along with increasing of rotating speed, automatically reduce inlet amount along with the reduction of running speed.

Detailed description of the invention
This controls the stone mill of charging automatically, comprise mill frame, mill, engine, lower fan abrasive disc, hopper and automatically control feed arrangement, it is characterized in that: under mill frame (1), engine (2) is housed, mill frame (1) there is mill (3), mill (3) there is lower fan abrasive disc (4), lower fan abrasive disc (4) there is upper fan abrasive disc (5), upper fan abrasive disc (5) has hopper (6), and hopper (6) is equipped with along place and automatically controls feed arrangement (7), (7.1), (7.2), (7.3), (7.3.1).
Above-described automatic feeder, is characterized in that: hang a fork (7) on the upper edge of hopper (6), fork (7) bottom hangs with pendulum (7.1), and middle part is connected with charging activity flashboard (7.3).
Above-described fork (7), is characterized in that: hanging over hopper has screw (7.2) adjustable up and down along on the fork at place, and the pendulum that bottom hangs is the pouring weight that multi-disc can fold extension.
Above-described charging activity flashboard (7.3), it is characterized in that: this charging flashboard is made up of upper and lower two shoe brake plates, horizontal elongated hole is had in the middle of upper flashboard, this horizontal elongated hole can be overlapped into feed-throughs with the hole of growing crosswise of lower movable flashboard centre, also can partly overlap controlled charging hole, also can non-overlapping copies, become the blind hole of closing charging; Lower movable flashboard (7.3) right-hand member is flexibly connected with fork (7) middle part.
Specific works situation
When this stone mill of needs works, as long as start engine (2), engine (2) is fanned abrasive disc (5) and is rotated on driving, hopper (6) also and then rotates, hang over hopper (6) and then rotating along upper fork (7), the pendulum (7.1) hanging over fork (7) bottom creates centrifugal force when rotating, outwards make centrifugal motion, fork (7) is also outwards arranged, movable flashboard (7.3) is pulled outwards to move, make the horizontal elongated hole on movable flashboard (7.3) overlapping with the horizontal elongated hole on the fixing flashboard (7.3.2) be fixed on hopper (6) or partly overlap into through hole, namely raw material enters by through hole that wear eye (5.1) is inner processes, when rotating speed height, pendulum (7.1) drives fork (7) to strengthen with the angle of vertical line, pull the distance of the outside movement of movable flashboard (7.3) also just to strengthen, two horizontal elongated holes (7.3.1) and (7.3.2) overlapping part also strengthen thereupon, and the inlet amount of raw material also just increases automatically, when rotating speed is low, the centrifugal force of pendulum (7.1) reduces, and drive fork (7) to reduce with the angle of vertical line, promotion activity flashboard moves inward, and the position of two horizontal elongated holes (7.3.1) and (7.3.2) overlap is also reduced thereupon, it also reduces inlet amount, when stopping operating, fork (7), under the effect of pendulum (7.1) gravity, overlaps with vertical line, and fork (7) also reaches inner dead point with regard to promotion activity flashboard (7.3), and namely two horizontal elongated holes are closed into blind hole mutually, namely automatically stops charging.
