Abstract

The present invention relates to a fine crushing machine which comprises a machine frame and a transmission mechanism. A fine crushing mechanism comprises a moving jaw plate which can swing or move up and down or can swing and simultaneously move up and down. The present invention is characterized in that the fine crushing mechanism is composed of the moving jaw plate and a rotary roller wheel, wherein the rotary roller wheel is arranged in the position corresponding to the moving jaw plate; a revolution center of the roller wheel can be fixed or deviated from a fixed axial lead, and the roller wheel is fixed on the machine frame by a shaft. The fine crushing machine changes a fixed jaw plate into one rotary roller wheel, the friction among the materials and the roller wheel is rolling friction, the friction is small, the circumferential wear is uniform, the service life is long and the cost is low. The materials not only can be discharged to the lower part under the function of gravity, but also can be accelerated to move to a discharge opening of the lower part under the promotion of the moving jaw plate and the roller wheel moving to the lower part, which can avoid plugging. The fine crushing machine increases the material bed crushing effect due to the generation of the rolling function of the roller wheel, and can enhance the crushing speed and the crushing rate, enlarge the crushing effect, and have large output capacity and small fineness; the fine crushing machine is not only suitable for various materials, but also for fine grinding materials and powder wet materials.

Description

Fine crusher

Technical field

The invention belongs to a kind of Fine powder milling machine device, be specifically related to a kind of architecture advances, be mainly used in ore dressing, building materials, iron and steel, road and bridge and the chemical industry jaw crusher.

Background technology

In jaw crusher, its mechanism in small, broken bits is made of two jaws, and the fragmentation of material is carried out between two jaws.Swing jaw is made periodic wobble around hanging axle to fixed jaw, and when the close fixed jaw of moving jaw, the ore that then is positioned between two jaws is crushed, splitting and flecition and fragmentation.When moving jaw left fixed jaw, Po Sui ore was discharged through gape under the gravity effect.This kind crushing mechanism is because a jaw is fixed, and the friction between this jaw and the material is sliding friction, and material is big and wear and tear inhomogeneously by time wearing and tearing, and the wearing and tearing of jaw hypomere are big, and blanking is slow, and productive rate is low.

Summary of the invention

Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides that a kind of blanking is fast, productive rate is high, wear extent is little and even, long service life, the little crushing mechanism of low, the broken fineness of cost.

The present invention solves its technical problem by following technical scheme.It comprises frame, transmission mechanism, mechanism in small, broken bits, described mechanism in small, broken bits comprises the moving jaw plate that moves up and down when can swing or move up and down or swing, it is characterized in that mechanism in small, broken bits forms by aforementioned moving jaw plate with at the rotatable running roller that this moving jaw plate correspondence position is provided with, its fixedly axial line can be fixed or depart to this running roller centre of gyration, is fixed on the frame by axle; Described moving jaw plate working face is a curved surface, and this surface is shiny surface with the running roller surface or becomes waveform curved surface shape.The upper end centre of gyration line of described moving jaw plate can overlap with the pto shaft center line in the transmission mechanism, the other end links to each other with endplay device, described endplay device comprises connecting rod, forward thrust plate and back thrust plate, forward thrust plate one end and moving jaw plate lower end join, the other end and an eccentric ratio lower end join, this connecting rod lower end joins with back thrust plate one end again, and the back thrust plate other end is hinged on the frame.The moving jaw plate upper end centre of gyration also can depart from the pto shaft center line in the transmission mechanism, the other end links to each other with endplay device, described endplay device comprises thrust plate, this plate one end and moving jaw plate lower end join, the other end and a voussoir that can move up and down join, and the voussoir that this voussoir and another are positioned on the frame is fitted mutually.

It is a rotatable running roller that the present invention changes fixed jaw, and the friction of material and running roller is rolling friction, thereby it is little to rub, and the circumference wearing and tearing are even, long service life, and cost is low.Simultaneously when moving jaw to running roller near the time, moving jaw not only can swing, move up and down but also can produce, owing to constantly rotate during running roller work, the material of passive like this jaw and running roller clamping can be rolled, splitting and flecition and fragmentation, and because the effect of frictional force, can impel running roller to do clockwise rotation downwards, when move in the bottom, material be carried out roll-in in running roller and moving jaw while and pulverize.Material not only can be dependent under the effect of gravity to the bottom discharging like this, also can quicken to move to the bottom discharge gate at moving jaw and running roller under the promotion of bottom motion simultaneously, can avoid putty.The present invention pulverizes effect because the generation of running roller roll extrusion effect has increased the bed of material, can improve broken speed and percentage of damage, increases crushing effect, and output is big, and fineness is little, not only is suitable for various materials, and is suitable for finer abrasive and powder wet feed.The running roller centre of gyration of the present invention also can depart from its fixedly axial line, can further increase the effect of rolling.
