Abstract

A solid waste crusher is composed of feeding hopper, discharge port and crushing system consisting of machine base and two rollers installed in said machine base, which are two parallel and non-uniform-speed shafts with cutter wheel and anvil wheel arranged alternatively, the cutter wheel on one shaft is engaged with the anvil wheel on another shaft, the cutters axially spread along single spiral line are uniformly distributed on the cutter wheel along circumference, and the scraper knives opposite to the anvil wheels are fixed to both side walls of machine base.

Description

Waste crusher

The utility model relates to a kind of disintegrating machine, particularly relates to a kind of waste crusher.

Widely used disintegrating machine has following several in the general industry production: jaw crusher, gyratory crusher, gyratory crusher, hammer mill, impact breaker, kibbler roll, more than these several disintegrating machines, all be to adapt to a kind of specific material to carry out fragmentation, just can not carry out fragmentation effectively as the mixed waste of compositions such as cloth, paper, wood, rubber, plastics.

The purpose of this utility model provides a kind of waste crusher, and it can the effectively broken mixture of being made up of cloth, paper, wood, rubber and plastics etc.

In order to achieve the above object, waste crusher of the present utility model comprises feed hopper, discharging opening and crushing system, described crushing system is made up of support and two rollers of being installed in the support, described pair of roller is the axle of two parallel reverse variable speed rotations, on two axles all arranged spaced break bar and anvil wheel is arranged, break bar on axle is relative with anvil wheel on another root axle, promptly break bar and the anvil on two axles taken turns mutual interlock, break bar is evenly distributed with cutting knife outside its circumference, cutter on the break bar on every axle is pressed single conchoid vertically and is launched, described support with the parallel both sides inwall of two rollers on fixed interval the scrape perching knife relative with anvil wheel arranged, scraping perching knife and anvil, to take turns adjoining face be circular arc.

As further improvement of the utility model, described feed hopper is that closed connects, and hagioscope and manhole are installed on the outside of feed hopper; Discharging opening is that closed is flexible coupling.

Because the break bar of waste crusher of the present utility model and anvil wheel are arranged spaced, and they are worked in coordination, promptly break bar on the axle of two reverse variable speed rotations and anvil wheel are corresponding mutually, can cut some toughness certain thickness material is not arranged by force, simultaneously because two reverse variable speed rotations of axle, so there is speed discrepancy in the break bar on two axles, so just, can tear the strong thin material of some toughness, so can be the effectively broken mixed waste of forming by cloth, paper, wood, rubber, plastics etc. of waste crusher of the present utility model; Secondly, the cutting knife on the break bar of the present utility model is pressed the arrangement that single conchoid launches vertically, makes it is not that whole cutting knifes is all done cutting action at the same time, can make required drive minimum under the situation of the identical shearing force of needs like this; The 3rd, perching knife and the anvil wheel of scraping of the present utility model matches, can prevent that the material that is not broken from dropping to below, play the effect of cleaning break bar and anvil wheel simultaneously.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

As shown in Figure 1, 2, waste crusher of the present utility model comprises feed hopper 3, discharging opening 6, reaches crushing system, charging aperture 11 is installed on the feed hopper 3, treat that broken waste material sends into feed hopper 3 from charging aperture 11, crushing system is made up of support 5 and two rollers of being installed in the support 5, and two rollers are the axles of two parallel reverse variable speed rotations, 18 supports of axle head usefulness bearing, for preventing that dust from leaking, bearing adopts labyrinth oil seal 16 sealings; Two one on axles are driving shaft, another root is a driven shaft, driving shaft 15 links to each other with motor reducer, power is provided, driving shaft 15 1 ends have driving gear 14, the same end of driven shaft 13 has driven gear 12, driving gear 14 and driven gear 12 are meshing, driving gear 14 is different with the diameter of driven gear 12, so when driving shaft 15 is rotated by driven by motor, driving gear of fixing on it 14 and driven gear 12 are because meshing relation, thereby drive driven gear 12 backward rotation, because driving gear 14 is different with the diameter of driven gear 12, so rotating speed difference of two axles, on two axles all arranged spaced break bar 2 and anvil wheel 7 is arranged, break bar 2 and anvil wheel 7 usefulness flat keys 9 are fixed on the axle, it is 7 relative that break bar 2 on axle and the anvil on another root axle are taken turns, promptly break bar and the anvil on two axles taken turns mutual interlock, break bar 2 is evenly distributed with cutting knife 10 outside its circumference, cutting knife 10 on the break bar 2 on every axle is pressed single conchoid vertically and is launched, this structure makes to have only one or two with the cutter of doing cutting action in a flash, so under situation with identical cutting force, the required drive minimum.Support 5 with the parallel both sides inwall of two rollers on fixed interval have with anvil and take turns the 7 relative perching knives 8 of scraping, scraping perching knife 8 and anvil, to take turns 7 adjoining faces be circular arc, after treating that broken material is sent to feed hopper 3 by charging aperture 11, drop on two rollers, at this moment the cutting knife 10 on the break bar 2 will hook the gap that material feeds break bar 2 and anvil wheel 7 downwards, cutting knife 10 forward to another root axle on the spacing of anvil wheel 7 for hour, material is cut off or tear fracture, material for some thin good toughness, because the difference of two roller rotating speeds, so will have speed discrepancy between the cutting knife on the break bar 2 on the diaxon, thereby when the material of these thin good toughness is hooked by cutting knife 10, will be torn, and then reach broken purpose; The effect of cleaning break bar and anvil wheel is played in scraping perching knife 8 and can cut off the material that is wrapped on the anvil wheel 7 or tear on support 5 two sides, can prevent that the material that is not broken from dropping to simultaneously below.Feed hopper 3, discharging opening 6 adopts closed to connect, and goes for the requirement of special operation condition, as the fragmentation of radwaste; Discharging opening 6 adopts the form that is flexible coupling, to reach the purpose of damping, hagioscope 1 is installed, on the outside of feed hopper 3 so that monitor the broken situation of the inside material at any time, access hole 4 also is installed, for the maintenance of machine when breaking down provides convenience on the outside of feed hopper 3.Journal stirrup 17 play supporting role when being used to install.
