Abstract

A knife-tooth cutting type breaking method and its apparatus for destroyer features that a moving toothed knife body which can be freely swung on the axle parallel to main axis and has tooth knives on it is used to replace original hammer, and the tooth-knife plate with knife-teeth is installed to surface of internal working cavity. Said apparatus is composed of rotating shaft, bearing plate installed to the rotating shaft, 2-9 axle pins on bearing plate, moving toothed knife bodie for each axle pin, knife plate with top teeth and the knife plate with main teeth. It is used to cut stone and has the advantages of high productivity, less vibration and long service life.

Description

The cutter tooth cutting type breaking method and the device thereof that are used for disintegrating machine

The present invention relates to a kind of preparation method and device thereof of stone disintegrating machine.

At present, disintegrating machine of the prior art generally all adopts and impacts the mode of beating and pushing stone with the stone fragmentation, this simple employing impacts the disintegrating machine of beating the extruding stone, its shortcoming is: energy consumption is big, efficient is low, shake greatly during work, parts such as its machine shaft and bearing thereof are easily damaged.

The objective of the invention is: a kind of high efficiency, the low cutter tooth cutting type breaking method and the device thereof that are used for disintegrating machine of vibrations are provided.

The present invention is achieved in that its method is made into the movable serrated knife body that can freely swing for the hammer that impacts with disintegrating machine on the axle parallel with main shaft, on movable serrated knife body, have serrated knife, and on the work internal chamber wall of disintegrating machine, install the serrated knife plate that has cutter tooth, can make the stone material processed to the cutting that not only is subjected to movable serrated knife body with cut in disintegrating machine like this, but also be subjected to the cutting of the serrated knife plate that has cutter tooth installed on the work internal chamber wall of disintegrating machine; Its concrete device is: the casing of disintegrating machine is made into upper machine body (14) and lower body (15), and its rotating shaft (8) can be rotated by driven by motor, support plate (7) is installed in rotating shaft (8), on the same circumference on the support plate (7), be evenly distributed with 2～9 pivot pins (9), make the axis of each pivot pin (9) parallel with rotating shaft (8), on each pivot pin (9), all be equipped with one and can go up the movable serrated knife body (6) of swing at pivot pin (9), and make and have serrated knife (2) on the movable serrated knife body (6), at the charging aperture place of upper machine body (14) safe unilateral gate (1) is installed, top in upper machine body (14) and side are equipped with apical tooth knife plate (3) and main serrated knife plate (4), the below of going up main serrated knife plate (4) at upper machine body (14) is equipped with and can upward upper sieve (11) be installed and can passes through bolt (16) and regulate lower screen (12) and the sieve support plate (13) that moves in the below of rotating shaft (8) at lower body (15) by regulating the adjustable serrated knife plate (5) that bolt (10) moves.

Owing to adopted technique scheme, the present invention compared with prior art has high efficiency, the low advantage of vibrations.During work, after entering in the machine by unilateral gate (1) the material piece of need fragmentation, its just the serrated knife (2) on the movable serrated knife body (6) of high-speed motion promptly to the material piece cut, cut, split and cut, and will expect that simultaneously piece impinges upon on the blade on main serrated knife plate (4) and the apical tooth knife plate (3), thereby make the material piece be subjected to cutting for the first time of three aspects, cut, split, cut, dropped out by adjusted good sieve aperture after the cutting processing for the second time being undertaken by adjustable serrated knife plate (5) again under the drive of movable serrated knife body (6) by the material piece of initial partitioning, go up material piece greater than sieve aperture and can cut back again by the cutter tooth of movable cutter hub (6) (2) and pass through sieve aperture for dropping on upper sieve (11).Because the present invention is when the powder shivering material, it mainly is the mode that adopts the cutter tooth cutting or hack, required strength is significantly less than the strength that agent is pressed, thereby not only reduced required motor power, reduced energy consumption, but also improved working (machining) efficiency greatly and reduced vibrations, thereby also prolonged the life-span of machine components widely.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the A-A partial sectional view of accompanying drawing 1.

Enforcement of the present invention is sharp: rotating shaft (8) is installed on the lower body (15), the type of belt drive of power motor and rotating shaft (8) can adopt traditional type of belt drive of prior art, in rotating shaft (8), install support plate (7), making rotating shaft (8) can drive support plate (7) rotates, on the same circumference on the support plate (7), 2～9 pivot pins (9) are installed by evenly distributing, and make the axis of each pivot pin (9) parallel with rotating shaft (8), on each pivot pin (9), all install a movable serrated knife body (6), movable serrated knife body (6) can be freely swung on pivot pin (9), serrated knife (2) is produced in front end and side at movable serrated knife body (6), the profile of tooth transverse cross-sectional shape of serrated knife (2) can be made into triangle, rectangle, shapes such as camber line shape, a safe unilateral gate (1) is installed at charging aperture place at upper machine body (14), apical tooth knife plate (3) and main serrated knife plate (4) are installed in top in upper machine body (14) and side, the cross section serrated knife shape of apical tooth knife plate (3) and main serrated knife plate (4) also can be made into triangle, rectangle, shapes such as camber line shape, loading onto in the below of the last main serrated knife plate (4) of upper machine body (14) can be by regulating the adjustable serrated knife plate (5) that bolt (10) moves, go up the below of rotating shaft (8) at lower body (15) upper sieve (11) is installed, sieve support plate (13) is fixed on the lower body (15) of upper sieve (11) below, between the below of upper sieve (11) and sieve support plate (13), installs one and can pass through the mobile lower screen of bolt (16) adjusting and (12).
