Abstract
The utility model relates to a double-crank impact jaw crusher used for crushing ore, comprising a machine frame, a motor, a static and a moving jaw plates, a lining plate, an upper eccentric shaft, a driving wheel and a moving jaw. The utility model is characterized in that the lower part of the moving jaw is provided with a lower eccentric shaft which is in parallel with the upper eccentric shaft; a driven wheel is arranged on the lower eccentric shaft; the bearing sleeve of the lower eccentric shaft is fixedly connected with the back part of machine frame through an adjustment connecting rod whose length can be adjusted. Because the moving jaw can make use of the inertia force and the impact force when in use and parallel impact the static moving jaw plate, the structure can greatly decrease the idle work consumed by the abrasion of material, the phenomena of over crushing and over compacting can be reduced, and the crushing efficiency and the lifetime of the wearing parts can be increased.
Description
The utility model belongs to the crushing technology field of solid material, specifically to having the improvement of jaw crusher now.
Jaw crusher is one of capital equipment of mine ore dressing crushing operation, it is the crushing mechanism that comparatively generally adopts at present, though have simple structure, reliable operation, characteristics such as easy to manufacture, easy to maintenance,, therefore have following shortcoming owing to adopted crank and rocker mechanism:
1, in shattering process, near stroke minimum in the moving jaw plate (being connecting rod), the bottom makes herein that stroke does not satisfy the required decrement of ore reduction, results in blockage.
2, since moving jaw plate be in operation, have go up to press, down from or go up from, the dancing that presses down, make the broken material in top can not arrive corresponding ideal position smoothly, thereby influenced the smooth discharge of material.
3, moving jaw plate force-bearing situation complexity, be local from top to bottom or not a half stressed, also be live load, do not give full play to and utilize crushing force like this, cause energy loss bigger.
4, moving jaw is connected the subordinate and slides and be similar to rolling friction with rocking bar, and wear extent is big, and can not accurately guarantee physical dimension, the jaw running orbit is out of shape, thereby has caused horizontal throw to reduce gradually, makes output decline.
The purpose of this utility model provides that a kind of double-crank connecting rod back and forth impacts, crushing, splitting, crooked comprehensive broken jaw crusher.
The purpose of this utility model is achieved in that it includes frame, motor, quiet jaw, moving jaw plate, liner plate, goes up eccentric shaft, goes up the driving wheel on the eccentric shaft, moving jaw, it is characterized in that the one following eccentric shaft parallel with last eccentric shaft being set in the bottom of moving jaw, be equipped with driven pulley on the eccentric shaft down, on the bearing holder (housing, cover) of following eccentric shaft, be fixedly connected on the rear portion of frame by the adjusting connecting rod that can adjust its length.During use, upper and lower eccentric shaft (crank axle) rotates synchronously, moving jaw drives sewing jaw by bump quiet jaw (crushing shell), wink is promptly left, back and forth synchronously parallel moving, thereby make moving jaw plate start crushing force simultaneously, finish the crushing, splitting of ore materials, crooked combined process along the total length working face.
Because what the utility model adopted is drag link, each track of its moving jaw is identical, upper and lower same moved further, horizontal throw (one of important indicator of decision output) is by the optimal design of the required decrement of ore reduction, accurately, reliably, thus guarantee ore materials crusher chamber by down under finish disposable fragmentation, discharge is smooth, unobstructed, and can pass through high rotating speed, significantly improve crushing efficiency.More considerable is, has solved that former single toggle jaw crusher cann't be solved, in, horizontal throw minimum between the bottom, putting with this in the moving jaw formula work is a swing, causes part or part working face to participate in the problem of broken material.And press the jaw formula machine of this structural design, and crusher chamber top and the bottom synchronous working, material, ore rely on gravity in all fragmentations in time of each height and position, discharge rapidly, have eliminated the shortcoming of protomala formula machine.Make its topmost performance indications, a hour output significantly improves.Metal consumption descended when the metal unit consumption was separate unit, its in service life significant prolongation, energy savings reduces consuming relatively, this structure will be the renewal product of existing jaw crusher undoubtedly.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is a structural representation of the present utility model.
By shown in Figure 1: concrete structure of the present utility model includes frame 1, quiet jaw 2, liner plate 3, moving jaw plate 4, is fixed with eccentric shaft 11 on the top of disintegrating machine, is equipped with driving wheel 6 on last eccentric shaft; The one following eccentric shaft 10 parallel with last eccentric shaft is set in the bottom of the motor-driven jaw 7 of fragmentation, is being equipped with driven pulley 5 on the eccentric shaft down.Be fixed with a lever regulated seat 12 that is connected with the threaded one end of regulating connecting rod 8 on the bearing of following eccentric shaft, the other end of regulating connecting rod is fixedlyed connected with the frame rear portion by insuring bearing pin 9.During use, by driven by motor drive pulley (driving wheel), driving wheel drives driven pulley by the V-belt, thereby guaranteed upper and lower eccentric shaft (being upper and lower crank) run-in synchronism, thereby make the parallel swing in jaw 7 front and back,, leave bump again by bump, the working in reciprocating mode of leaving again, thus reach the purpose of breaking ores.Improve a little on the basis of the present utility model, just available same moving jaw device manufactures the jaw crusher of double crashing cavity.The idle period of former type is shortened greatly, the motor load equilibrium, crushing efficiency significantly improves.
Claims (2)
1, a kind of double-crank impacts jaw crusher, it includes frame, motor, quiet jaw, moving jaw plate, liner plate, goes up eccentric shaft, goes up the driving wheel on the eccentric shaft, moving jaw, it is characterized in that the one following eccentric shaft parallel with last eccentric shaft being set in the bottom of moving jaw, be equipped with driven pulley on the eccentric shaft down, on the bearing holder (housing, cover) of following eccentric shaft, be fixedly connected on the rear portion of frame by the adjusting connecting rod that can adjust its length.
2, jaw crusher according to claim 1, the lever regulated seat that it is characterized in that regulating connecting rod one end and being fixed on bearing holder (housing, cover) is threaded, and the other end is fixedlyed connected with the frame rear portion by the insurance bearing pin.
