Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Fig. 1 is perspective view of the present utility model;

Fig. 2 is for being used the overall structure schematic diagram of a kind of plastic breaker of the present utility model.

The specific embodiment

With reference to accompanying drawing, plastic breaker moving knife component of the present utility model comprises the turning cylinder 10 that can be connected with engine 5 power, is packed in the triangle tool rest 11 on turning cylinder 10 and by bolt 12, is arranged on three cutting blades 13 on 11 3 limits of triangle tool rest respectively, wherein, weighting distribution wheel is installed in a wherein end of turning cylinder 10, driven pulley is installed in the other end, on the power output shaft of engine 5, drive pulley is installed, between drive pulley and driven pulley, is connected belt 14.Turning cylinder 10 adopts bel-drivenn form, and weighting distribution wheel is set can increase rotator inertia.The front end cutting edge of cutting blade 13 leans out triangle tool rest 11, on triangle tool rest 11, at the rear portion of each cutting blade 13, is respectively equipped with blade Telescopic positioning device.The preferred blade Telescopic positioning device of the utility model comprises that the block 15 that is fixed on triangle tool rest 11 and spiral shell are contained on block 15 and withstand on the puller bolt 16 of cutting blade 13 rearward end.Cutting blade 13 is arranged on triangle tool rest 11 by bolt 12, on cutting blade 13, can offer locating hole 17, because locating hole 17 coordinates for installing with bolt 12, can there is certain interval between the two, this kind of blade Telescopic positioning device is set is to have utilized above-mentioned gap, by rotation puller bolt 16, can carry out trickle adjustment to the length that leans out of cutting blade 13 cutting edges.

Structure for triangle tool rest 11, as shown in the figure, the preferred triangle tool rest 11 of the utility model is comprised of the spaced set square 111 of polylith, offers and equates with the quantity of set square 111 and locating hole 17 one to one, the interior bolt 12 that all installs of each locating hole 17 on cutting blade 13.The triangle tool rest 11 of this kind of structure, the gap between set square 111 can hold material, thereby can increase the inventory that crushing chamber holds.In addition, block 15 and puller bolt 16 are all set on every set square, can carry out trickle adjustment to the deflection angle of cutting blade 13.

The above-mentioned adjustment for cutting blade 13 is all the trickle adjustment that utilized the gap between locating hole 17 and bolt 12 to carry out, more preferred version is that locating hole 17 is strip hole, thereby can to cutting blade 13 lean out length and left and right angle excursion is significantly adjusted, the setting angle that can more be conducive to find accurately cutting blade 13, has facilitated with ledger-plate 4 and has coordinated effectively and cut.In addition, whole disintegrating machine is after long-time use, cutting blade 13 there will be cutting edge to damage, now need cutting blade 13 to remove and carry out cutting edge reparation, cutting edge position now will inevitably change, if adopt conventional fixed mounting means, will inevitably make the installation site of cutting blade 13 cutting edges undesirable or directly cause cutting blade 13 unavailable, adopt said structure, can avoid the generation of above-mentioned situation, cutting blade 13 can be reused after repairing.

With reference to accompanying drawing, triangle tool rest 11 is arranged side by side two covers along the length direction of turning cylinder 10, wherein a set of than many 30 degree of the another set of anglec of rotation with respect to turning cylinder 10 in two cover triangle tool rests 11, in order to install firmly, as shown in Figure 1, on turning cylinder 10, in the both sides of triangle tool rest 11, be separately installed with two block plates 18.In aforementioned, every cover triangle tool rest 11 is all and polylith set square 111 forms, set square 111 offers at center suit hole, utilize suit hole to be fixedly set on turning cylinder 10, each set square 111 that forms first set triangle tool rest 11 is identical with respect to the anglec of rotation of turning cylinder 10, from one end of turning cylinder 10, look, three angles of each set square 111 overlap.And for the set square 111 that forms another set of triangle tool rest 11, it is equivalent to than front a set of 30 degree that rotated more.After two cover triangle tool rests 11 are installed on turning cylinder 10, from wherein one end of turning cylinder 10, look, as shown in Figure 2, six dihedrals in two cover triangle tool rests 11 become a hexagon.In said structure, first, when adopting a set of triangle tool rest 11, for a ledger-plate 4, turning cylinder 10 rotates and within one week, has three stock removal actions, and while adopting two cover triangle tool rests 11, for a ledger-plate 4, turning cylinder 10 rotates a weekly assembly and produces six stock removal actions, can effectively improve stock-removing efficiency.In addition, the tool-apron structure that adopts this kind to be crisscross arranged, cutting blade 13 is evenly distributed on each position, can avoid occurring cutting dead angle, thereby guarantee good effect in small, broken bits.

With reference to Fig. 2, for using a kind of plastic breaker of the present utility model, the discharging mechanism that it comprises frame 1, is located at the crushing chamber 2 in frame 1, the feeding mechanism being communicated with the top of crushing chamber 2 and is communicated with crushing chamber 2 bottoms, in crushing chamber 2, crushing cutter is installed, feeding mechanism comprise top closure and wherein a sidewall feed hopper 3 of opening 30 is set and is connected to the charging tray 31 on above-mentioned opening 30.Tripper 9 is installed feed hopper 3 on the madial wall that is provided with opening 30 1 sides and this tripper 9 is comprised of two V-shaped dividing plates 91 of overlap joint.For feeding mechanism, on feed hopper 3 sidewalls, establish opening 30 and by the 31 places charging of charging pallet, can make material directly not fall into crushing chamber 2, but the buffering of first passing through charging pallet 31, fall into gradually more afterwards crushing chamber 2, thereby can avoid material in feed hopper 3 and the interior obstruction of crushing chamber 2.Tripper 9 becomes the interior separation of feed hopper 3 in the passage of bending, makes material after the buffering of repeatedly turning back, just fall into crushing chamber 2 feed hopper 3 is interior, has played the effect of further buffering charging.

With reference to Fig. 2, crushing cutter comprises the moving knife component being rotatably installed in crushing chamber 2 and is fixedly mounted on the ledger-plate 4 on crushing chamber 2 sidewalls, the engine 5 being connected with moving knife component power is installed in frame 1; The bottom of crushing chamber 2 is provided with arc bushing 6, offers a plurality of small openings 60 on bushing 6.Discharging mechanism comprises the material-falling hopper 7 that is arranged on arc bushing 6 belows and the sub-material baffle plate 8 that is arranged on material-falling hopper 7 tops.In crushing chamber 2, carry out material cutting and shatter, the small particles material after pulverizing leaks down by small opening 60.The effect of sub-material baffle plate 8 is the small particles material after pulverizing can be divided into two strands enter material-falling hopper 7, avoids material to stop up in material-falling hopper.As shown in Figure 2, the inverted V-shaped that sub-material baffle plate 8 is formed by two boards overlap joint.

Turning cylinder 10 in moving knife component of the present utility model is rotatably installed on the locular wall of crushing chamber 2 and is driven by engine 5.

In sum, the utility model is not limited to the above-mentioned specific embodiment.Those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
