The strong double-tooth-roller grading crusher has the advantages that product discharging granularity is adjustable, the structure is compact, crushing capacity is high, tooth plate fixing is reliable, maintaining is convenient, using cost is low, mounting is convenient, and adjusting is convenient.
Description
Technical field:
The utility model relates to a kind of powerful double teeth roller Sizing Crusher that installs secondary crushing device additional that is applicable to the industry lump materials such as colliery, electric power, mine, chemical industry.
Background technology:
At present, domestic in, the double-geared roller crusher of use in small, broken bits, mainly there is the problem of following several respects: 1. little, the discharging-material size of the ratio of reduction can not be adjusted.The operation principle of double-geared roller crusher is formed three dimensions and is determined the size of material granularity by the profile of tooth of two discaling roll cross arrangements, in the time of the less discharging-material size of needs, tooth Shape Design is less, and therefore having limited feed size can not be excessive; Because on-the-spot material exists multiple uncertain factor (as size of the intensity of water content, material, material etc.), be prone to material discharging-material size off-gage phenomenon in addition, solution need redesign tooth plate; In the time that equipment uses for a long time, because tooth plate wearing and tearing cause discharging-material size overproof, now also need to change tooth plate, because tooth plate is expensive, increase client's use cost.2. tooth plate fixed form is unreliable.Owing to adopting bolt-connection, bolt is subject to twisting resistance and impulsive force repeated action occurs that elongation fractures, and tooth plate comes off and very easily causes device damage.3. tooth plate material is selected potassium steel mostly, service life limited and wearing and tearing after cannot repair, again change tooth plate expensive.Four, connect because discaling roll and reductor often adopt gear coupling, noise is large, maintenance inconvenience.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of powerful double teeth roller Sizing Crusher that installs secondary crushing device additional is provided, have that product discharge granularity is adjustable, compact conformation, breaking capacity are large, tooth plate fixing reliable, easy to maintenance, use cost is low, noise is little, be convenient to the advantages such as installment and debugging.
The technical scheme that the utility model is taked for technical solution problem is:
A powerful double teeth roller Sizing Crusher that installs secondary crushing device additional, comprises base and crushing system, and described crushing system below installs the broken beam of secondary crushing device additional, and broken beam bottom is provided with adjusting cushion block; Described crushing system comprises two cover discaling roll fragmentation cells, every cover discaling roll fragmentation cell includes motor, fluid coupling, reductor, elastic dowel pin shaft coupling, discaling roll and discaling roll axle, described motor connects with reductor by fluid coupling, described reductor drives discaling roll axle to be rotated by elastic dowel pin shaft coupling, is distributed with staggered crushing teeth on discaling roll.
Described discaling roll comprises discaling roll axle, tooth plate seat, tooth plate, round nut, stretching screw and voussoir, and described tooth plate adopts voussoir tension mode to fix.
Described elastic dowel pin shaft coupling comprises discaling roll axle head half a coupler, reductor end half a coupler, elastomer and pin, and half a coupler is equipped with at reductor and discaling roll axle two ends, and pin one end is contained on half a coupler, and the other end is installed described elastomer.
The utility model solves by increasing secondary crushing device the problem that the ratio of reduction is little, discharging-material size is adjustable, by Dual-motors Driving discaling roll broken material, two discaling rolls are to equipment center place rotation, impose on material cutting power and tensile force to material primary crushing by the staggered crushing teeth that distributes on discaling roll; Discaling roll drives material to act on broken beam, realizes again broken.Owing to having adopted two-stage crushing, in the time that one-level is broken, can design larger profile of tooth, with the larger material of fragmentation.Discharging-material size, by the broken beam control of secondary crushing device, can obtain the larger ratio of reduction like this.Under broken beam, cushion block is installed, realizes material discharging-material size by adjusting pad tile height adjustable.Client can be according to the actual conditions spacer tile height of on-the-spot material, with the raw meal particle size that obtains requiring in the time of the equipment of use.In the time that tooth plate wearing and tearing discharging-material size becomes large, also can adopt this way to regulate, improve the utilization rate of tooth plate, reduce use cost.
Discaling roll of the present utility model is mainly by discaling roll axle, tooth plate seat, tooth plate, round nut, stretching screw and voussoir composition, assembling mode is at main shaft one end design shaft shoulder, the other end is designed with screw thread, after tooth plate seat being fitted on main shaft by special equipment, lock by double nut mode, main shaft adopts flat key to connect with transmitting torque with tooth plate seat, the unique voussoir fixed form of fixing employing of tooth plate and tooth plate seat, stretching screw tension voussoir is close to tooth plate seat and tooth plate, the twisting resistance producing when toothed plate crushing material and impulsive force have voussoir to pass to tooth plate seat, avoid the phenomenon that screw is direct stressed and then rupture.In addition this fixed form of voussoir also have easy for installation, fastening reliable, dismantle the advantages such as rapid.
Elastic dowel pin shaft coupling of the present utility model is to be connected with pin and two half a couplers, and pin is flexible, can compensate diaxon relative displacement, and has the effect of buffering shock-absorbing; Simultaneously elastic dowel pin shaft coupling also have lightweight, easy for installation, noise is little, the advantage such as non-maintaining.
The utility model ratio of reduction can be adjusted according to the actual material situation in scene, can reach the discharging-material size of expectation.Novel voussoir tension mode locking, has solved " falling tooth plate " phenomenon of tooth plate appearance with bolts, easily installs and connects fastening reliable.Tooth plate adopts novel wear resistant alloy material, long service life.Motor adopts elastic dowel pin shaft coupling to connect with reductor, can compensate two axial displacements, cushions in addition the effect of shock-absorbing.The machine, by the long-term use in colliery, has the advantages such as the bulk of eating ability is strong, powder rate is low excessively, discharging-material size is even, safe and reliable, fault is few.
