It is characterized in that the double-cavity double-movable jaw is provided with a spring for restoring the movable jaw, a discharge port adjusting device and a feeding adjusting baffle. 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
The utility model relates to jaw crusher, is 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, new architectures such as the jaw crusher of different supporting forms, low frame jaw crusher have now appearred, these types generally have mechanical performance preferably, adopt hypsographic curve chamber type, less eccentric throw, bigger hunting frequency, be crowded with formula feed-types, 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 utility model provides 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 jaw 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 on the 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 utility model 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.
Description of drawings:
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 gate adjusting device schematic diagram.
Accompanying drawings further describes as follows to the utility model:
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 jaw (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), the crack adopts seal (21) dustproof, grease proofing between two moving jaw bearing blocks, reaches sealing function when two moving jaws are swung relatively.
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 loadly, 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 specification adjusting pads (16) is filled up in bracket seat back, adjusting work is promptly finished, to adapt to the requirement of different material crushed product size.This device also can 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 utility model is in small, broken bits to material, be contained in moving jaw with two, decide the deep cavity shape special-purpose in small, broken bits of 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, eccentric main axis drives moving jaw with higher hunting frequency and less off-centre, liner plate is flapped toward with the particular track of eccentric main axis eccentricity and liner plate parameter at each position of upper, middle and lower of moving jaw decides the jaw liner plate, to lead successively and pay material extruding in the crusher chamber, broken, 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).
