Abstract
The utility model discloses a non-pressing-force cleaning device of scrapers of a grinding mill, comprising two scrapers, wherein the two scrapers are respectively arranged below a grinding roller of the grinding mill; each scraper is arranged at one end of each cross rod at the upper part of a linking mechanism; limiting mechanisms are respectively arranged at the positions above the middle parts of the cross rods; the other ends of the cross rods are respectively coupled with a spring; and the other ends of the springs are respectively connected with bolts fixedly connected with a wall. Two hinged linking rods driven by a pneumatic system are arranged below the linking mechanism, two hooks are arranged on the upper linking rod, and the upper ends of the hooks are respectively connected with the lower parts of the cross rods at the scraper ends. The limiting mechanisms are limiting screws arranged on a wall. The non-pressing-force cleaning device has the advantages that the defects of the traditional pressing mechanism are overcome, and the pressing force among the grinding roller and the scrapers is eliminated under the operating state of the grinding mill, so that the service lives of the scrapers and the grinding roller are prolonged; and the limiting devices are simple in structure and convenient and accurate to operate.
Description
Technical field
The utility model relates to the flour mill scraper, especially relates to a kind of flour mill scraper cleaning plant that does not have thrust.
Background technology
At present, the mode that compresses of flour mill scraper hold-down mechanism mainly contains two kinds both at home and abroad.The one, with balancing weight scraper is directly tightened and the grinding roller hold down gag; The 2nd, the device that adopts spring carrier arm mechanism that scraper and grinding roller are compressed.Be that a kind of mode that compresses all exists following defective: can realize between scraper and the grinding roller compressing automatically, but the time there is thrust in the grinding roller running all the time between scraper and grinding roller, increase the wearing and tearing between scraper and the grinding roller, influences the service life of scraper and grinding roller.
Summary of the invention
The utility model purpose is to provide the flour mill scraper cleaning plant of eliminating the no thrust of thrust between scraper and the grinding roller under a kind of flour mill operating condition.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The flour mill scraper cleaning plant of the described no thrust of the utility model comprises two scrapers that place the grinding roller of wheat flour-milling below respectively; Said scraper is separately positioned on an end of link gear upper cross bar; The place, top position is provided with position-limit mechanism respectively in the middle part of being positioned at said cross bar; Below the cross bar other end, be connected with spring respectively, the other end of said spring is connected with the bolt that wall is connected mutually respectively.
Said link gear below is two gangbar that are hinged of pneumatic system driving, and the gangbar above being positioned at is provided with two hooks, and the upper end of said hook is connected with the bottom that said cross bar is positioned at the scraper end respectively.
Said position-limit mechanism is the stop screw that places on the wall.
The utility model advantage has been to overcome the defective of traditional hold-down mechanism, in the thrust of eliminating under the flour mill operating condition between grinding roller and scraper, prolong scraper and grinding roller service life, and stopping means is simple in structure, easy to operate accurate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in the figure, the flour mill scraper cleaning plant of the described no thrust of the utility model comprises two scrapers 3,4 that place grinding roller of wheat flour- milling 1,2 belows respectively; Said scraper 3,4 is separately positioned on an end of link gear upper cross bar 5,6; Be provided with position- limit mechanism 7,8 respectively being positioned at top position, said cross bar 5,6 middle part place; Below cross bar 5,6 other ends, be connected with spring 9,10 respectively, the other end of said spring 9,10 is connected with the bolt 11,12 that wall is connected mutually respectively; Two gangbar that are hinged 13,14 that said link gear below drives for pneumatic system; Gangbar 13 above being positioned at is provided with two hooks 15,16, and the upper end of said hook 15,16 is connected with the bottom that said cross bar 5,6 is positioned at the scraper end respectively; Said position- limit mechanism 7,8 is for placing the stop screw on the wall.
During use, bolt 11,12 is fixed on the framed side wallboard of flour mill, links, link through link gear and pneumatic system with spring 9,10; Under the situation of closing a floodgate, make hook 15,16 loosening through gangbar 13,14, be in the state that does not stress; At this moment, the pulling force of spring 9,10 compresses scraper 3,4 and grinding roller grinding roller 1,2, the beginning break-in; Through the regular hour, the surplus of reserving has in advance been ground, make the linear fully applying of scraper 3,4 and grinding roller 1,2; And do not have thrust, reach desirable duty; At this moment; Adjustment position- limit mechanism 7,8 withstands the upper end of cross bar 5,6 with stop screw and locks, and under working condition, is in this state, makes scraper 3,4 and grinding roller 1,2 not receive frictional force; And the binding on the cleaning grinding roller 1,2, the service life of prolongation scraper 3,4 and grinding roller 1,2.
