Abstract

The invention relates to a jaw crusher, which is suitable for crushing operation in the fields of metallurgy, building materials, chemical industry, medicine and the like. It is characterized by that said double-cavity double-acting jaw is equipped with spring for restoring moving jaw, discharge outlet regulating device and feeding regulating baffle plate. Compared with the prior art, the method realizes more crushing and less grinding, has large crushing ratio which can be improved to more than 10, and has high treatment capacity, fine and uniform product granularity, low energy consumption, excellent performance and reasonable structure.

Description

Double-chamber double-moving jaw crusher

The present invention relates to jaw crusher, be applicable to the crushing operation of metallurgy, building materials, chemical industry, medicine and other fields.

At present, the development of jaw crusher is mainly shown to type in small, broken bits and to the enhanced transformation of old-fashioned disintegrating machine.High speed development along with computer technology, now occurred the new architectures such as jaw crusher of different supporting forms, these types generally have mechanical performance preferably, adopt hypsographic curve chamber type, less eccentric throw, bigger hunting frequency is crowded with formula feed-types, has improved crushing effect, strengthened fragmentation, but majority is continued to use old model structure generally, just on performance, parameter, optimize to some extent and improve, and to all there not being the change of essence on structure, the operating characteristic.

The purpose of this invention is to provide a kind of how broken few mill, large reduction ratio, disposal ability height, product granularity is thin and evenly, low energy consumption, function admirable, disintegrating machine rational in infrastructure.

Double-chamber double-moving jaw crusher comprises frame, decides the jaw liner plate, moves jaw, moves jaw liner plate, transmission device, motor,

It is characterized in that:

The moving Hubei Province of a binaural axis holder structure and the moving jaw of monaural bearing block structure in opposite directions 180 ° inlay and be configured on the eccentric main axis; B is provided with the connected respectively spring that jaw is resetted in two ends in the middle and lower part of two moving jaws part; C is being provided with on the slideway by slipping bracket that bracket seat, the two ends that can move horizontally are hinged on bracket seat and moving jaw lower inside respectively at slideway, being connected the discharge gate adjusting device that the adjusting bolt that withstands on the frame is formed with the screwed adjusting nut of bracket seat welding, with the adjusting nut internal thread; D is provided with in the feed box inside above the material inlet and is fixed on the feed that is stuck on the feed box both ends of the surface arc chute on the bearing pin by bearing pin and regulates plate washer.

Owing to adopted technique scheme, the present invention and prior art ratio, realized how broken few mill, large reduction ratio, can bring up to more than 10, the disposal ability height, product granularity is thin and evenly, low, the function admirable, rational in infrastructure of power consumption, its efficient is higher by 80～90% than old jaw crusher.

Fig. 1 is a double-chamber double-moving jaw crusher master pseudosection.

Fig. 2 is the double-chamber double-moving jaw crusher side cutaway view.

Fig. 3 is a discharge adjusting device schematic diagram.

Accompanying drawings further describes as follows to invention:

Double-chamber double-moving jaw crusher comprises frame (11), decides jaw liner plate (9), moves jaw, moves jaw liner plate (10), transmission device (20), motor,

The moving Hubei Province (8) of binaural axis holder structure and the moving jaw (19) of monaural bearing block structure in opposite directions 180 ° inlay and be configured on the eccentric main axis (5), between two bearing blocks, adopt sealing (21) dustproof, grease proofing, when two moving jaws are swung relatively, reach sealing function.

Be provided with the connected respectively spring (14) that jaw is resetted in two ends in the middle and lower part of two moving jaws part, its effect is two moving jaws to be abutted against the bracket end of supporting with negative support pattern with pretightning force, no matter, disintegrating machine has zero load, and the spring that resets all can guarantee the correct operating position of moving jaw.

On slideway (17), be provided with the bracket seat (15) that can move horizontally by on slideway, slipping, two ends are hinged on the bracket (18) of bracket seat and moving jaw lower inside respectively, screwed adjusting nut (25) with the welding of bracket seat, the discharge gate adjusting device that is connected adjusting bolt (22) composition that withstands on the frame with the adjusting nut internal thread, when screwing the adjusting bolt, driving the bracket seat moves horizontally on slideway, when the bracket seat moves to moving jaw direction, force moving jaw close by means of bracket to deciding the jaw liner plate, when moving jaw liner plate when deciding the jaw lining board clearance and reach desired size, different specifications is filled up (16) pad at a high speed in bracket seat back, adjusting work is promptly finished, to adapt to the requirement of different material crushed product size.This device can also play the regulating and compensating role behind the wear liner.

Be provided with in the feed box above the material inlet (1) inside and be fixed on the feed that is stuck on the feed box both ends of the surface arc chute on the bearing pin by bearing pin (3) and regulate plate washer (2), adjusting is become owner of the quantity of paying crusher chamber from the top material flow, and then adjusts main operating efficiency of paying crusher chamber.

The present invention is in small, broken bits to material, with two deep cavity shapes special-purpose in small, broken bits that are contained in moving jaw, decide the surface curve composition of the liner plate on the jaw, when motor drives transmission device by V belt (24), moment of torsion is passed on the eccentric main axis, the particular track of eccentric shaft eccentricity and liner plate parameter is flapped toward decides the jaw liner plate, to lead successively and pay material extruding, fragmentation in the crusher chamber, material from material inlet to discharge gate at least through the shattering process more than 5 times, its efficient is higher by 80～90% than old jaw crusher, and the ratio of reduction can be brought up to more than 10.

In the accompanying drawing, backplate (4), pressing plate (6), bolt are paid (7), side guard plate (12), bolt (13), stabilizer (23).

Claims
