Abstract

The utility model discloses a combined multi-claw waste crusher which comprises support seats, wherein the support seats are provided with rolling bearings in an assembling manner by bolts on an engine base; two main shafts are arranged on the engine base in parallel; hydraulic motors which are connected on input shafts of planet-gear speed reducers drive the two main shafts to move in the opposite directions. The crusher is characterized in that four-eight claw-shaped combined conveniently-detachable cutters are uniformly distributed on the two main shafts along the peripheral directions, and the claw-shaped combined conveniently-detachable cutters and the two main shafts are fixed by flat keys. According to the crusher, the cutters are easy to detach, convenient to replace, and short in maintenance time, so that the using efficiency of the crusher is improved; the cutters can be repaired and used repeatedly, so that the use cost is greatly reduced; as the claw-shaped combined conveniently-detachable cutters can be connected with the two main shafts by the flat keys for operation, a long hexagon shape or a long spline shape required to be machined by a main shaft of a common crusher can be avoided, and the manufacture cost is reduced; as the multi-claw cutters are adopted, the sizes of crushed materials are small, the crushing ratio of the primary crushing is reduced; as a winding-preventing device is arranged, the condition that the materials wind the shafts can be avoided.

Description

Combined type multijaw waste material disintegrating machine

Technical field

The utility model relates to a kind of disintegrating machine, relates in particular to a kind of combined type multijaw waste material disintegrating machine for broken scrap metal, abandoned car housing.

Background technology

At the disintegrating machine that is used for broken solid waste, cutter is to affect the factor that disintegrating machine uses, and is because cutter all uses alloy tool steel to form through the manufacturing of special thermal treatment technique, expensive; Simultaneously cutter is as consumable accessory, can easily be damaged because of wearing and tearing, tipping, impact, needs repairing and changes.The waste material crusher cutter of commonly using both at home and abroad at present is to adopt monoblock type or welded type.Integral cutter needs integral replacing and reparation, and dismounting and maintenance time are long, and cost is high; Can only dismantle by the mode of flame cutting after the welded type cutter destroys, not only destroy cutter, also destroy the junction that is associated of cutter, cause that maintenance time is long, maintenance cost is high; By being welded and fixed cutter, the high temperature that produces during welding can cause localized tempering simultaneously, reduces tool surface hardness, has affected the cutter result of use; The cutter of pulling down has also been wasted resource because destruction can not be repaired use.

The utility model content

The technical problem that the utility model solves is the defective that overcomes prior art, and the combination detachable multijaw waste material disintegrating machine that a kind of cutter mounting or dismounting are convenient, can repair use, can reduce production costs is provided.

The utility model is included on the support by bolts assemblies bearing with rolling bearing, parallel on bearing two main shafts are housed, two main shafts of hydraulic motor drive that are connected on the planet-gear speed reducer power shaft are made move toward one another, it is characterized in that, be evenly equipped with in the circumferential direction of the circle 4-8 spare pawl type combination detachable cutter on two main shafts, pawl type combination detachable cutter is fixed by flat key and main shaft.

Described pawl type combination detachable cutter comprises rotary knife base, cutting knife, plastic cutter, hits cutter; Described rotary knife base is that tool rest and spacer are processed into one; Described plastic cutter is flexibly connected into assembly with cutting knife; The described cutter that hits is flexibly connected into assembly with cutting knife.(pawl type combination detachable cutter is applied for a patent in addition)

The described 4-8 spare pawl type combination detachable cutter that is evenly equipped with in the circumferential direction of the circle on two main shafts is that 2-4 is passed through respectively with the cutter assembly that hits cutter with the cutter assembly of plastic cutter and 2-4 CutCutter and rotary knife base are flexibly connected, and circumferentially uniform along rotary knife base.

Be provided with anti-winding device between described support and the combination detachable cutter, described anti-winding device is the arc line type pecten.

The utlity model has following beneficial effect: the mounting or dismounting of (1) cutter are simple, replacing is convenient, and maintenance time is short, has improved the disintegrating machine service efficiency; (2) cutter can be repaired, reuse, and greatly reduces use cost;

(3) carry out work because combination detachable cutter can connect with main shaft by flat key, avoided the long hexagon that common crusher axis need to process or grown spline-shaped, reduced the manufacturing cost of disintegrating machine; (4) owing to adopting multijaw type cutter, the material size after the fragmentation is less, has reduced the ratio of reduction of one-level fragmentation; (5) because anti-winding device being housed, can prevent that material from twining axle.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment is illustrated:

With reference to accompanying drawing:

On support 4, be equipped with bearing 3 with rolling bearing by bolt 5, parallel on bearing two main shafts 6 are housed, end at main shaft is processed with external splines, connects with inner spline housing on planet-gear speed reducer 2 output shafts, and hydraulic motor rotarily drives two main shafts and makes move toward one another.Be evenly equipped with in the circumferential direction of the circle 4-8 spare pawl type combination detachable cutter 7 on two main shafts, pawl type combination detachable cutter is fixing with main shaft 6 by flat key 8.

Described pawl type combination detachable cutter comprises rotary knife base, cutting knife, plastic cutter, hits cutter; Described rotary knife base is that tool rest and spacer are processed into one; Described plastic cutter is flexibly connected into assembly with cutting knife; The described cutter that hits is flexibly connected into assembly with cutting knife.

Described on two main shafts, be evenly equipped with in the circumferential direction of the circle 4-8 spare pawl type combination detachable cutter be with 2-4 with the cutter assembly of plastic cutter and 2-4 with the cutter assembly that hits cutter respectively by cutting knife and rotary knife base flexible connection, and circumferentially uniform along rotary knife base.

As shown in Figure 3, between the side plate of support and combination detachable cutter, establish special arc line type pecten 9, prevent that material from snarling main shaft.
