Detailed description of the invention

Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.

As Fig. 1, 2, shown in 3, a kind of bark shredder, it comprises frame 3 and rack-mounted feed hopper 1, crushing roller device, discharging opening 2, motor 6 and decelerator 5, described feed hopper 1 is positioned at the top of crushing roller device, discharging opening 2 is positioned at the below of crushing roller device, be connected with belt transmission by belt pulley between motor 6 and decelerator 5, decelerator 5 and crushing roller device are in transmission connection, some fluted discs 12 that described crushing roller device is evenly set on two roll shafts by two roll shafts 11 and interval are formed, fluted disc 12 layout interlaced with each other on two roll shafts 11, the end, the same side of two roll shafts 11 is engaged each other by the gear 7 that it is installed and is in transmission connection, wherein a roll shaft 11 is in transmission connection with decelerator 5, the two ends of two roll shafts are installed in frame 3 respectively by equipped bearing and bearing block.

As shown in Figure 5,6, the axle body of roll shaft 11 offers the axial pass trough 16 running through its both ends of the surface, the inner peripheral surface of described fluted disc 12 offers the keyway 15 with the corresponding adaptation of groove 13 on roll shaft 11, fluted disc 12 is sleeved on after on roll shaft 11 and is arranged in the groove on roll shaft and the keyway on fluted disc by bar shaped key between the two, realizes the radial location of fluted disc on roll shaft.

Axial displacement is produced for preventing the fluted disc 12 on roll shaft 11, entretoise annulaire 13 is provided with between adjacent fluted disc 12 on two roll shafts 11, and fluted disc on each roll shaft is corresponding with the entretoise annulaire on another roll shaft, also be connected by key between entretoise annulaire with roll shaft, the external diameter of entretoise annulaire is less than the external diameter of fluted disc.

Axial displacement is produced for preventing outermost fluted disc 12 or entretoise annulaire 13 on two roll shafts further, on two roll shafts, the end face outside of outermost fluted disc or entretoise annulaire arranges positioning sleeve 14, positioning sleeve 14 is set on roll shaft 11, and be threaded connection between positioning sleeve and roll shaft, and then achieve fluted discs all on two roll shafts and the axial location of entretoise annulaire on roll shaft.

As shown in Figure 4, described feed hopper 1 is also provided with two material scraping plate 9, two material scraping plates 9 to be arranged in parallel with roll shaft, two material scraping plates 9 are the corresponding outside being positioned at two roll shafts respectively, material scraping plate 9 is provided with some scraper teeth 10, and scraper tooth 10 lays respectively in the interval between two fluted discs on respective side roll shaft; Material scraping plate, for wiping the bark material be clipped on two roll shafts in adjacent fluted disc off, is ensure elimination effect, and preferably, the setting direction of two material scraping plates is along the tangential direction of the entretoise annulaire between fluted disc adjacent on two roll shafts.

Frame 3 is also provided with the governor motion for regulating two roll shaft spacing; Owing to having different demands to bark granular size, therefore, the spacing (namely adjusting the spacing between fluted disc from entretoise annulaire on two roll shafts) by adjusting two roll shafts obtains the broken bark particle of different size.

A kind of structure of described governor motion can adopt the adjusting bolt 4 by being positioned at outside two roll shafts to form, and adjusting bolt 4 is located in frame 3, and the end of adjusting bolt contacts with the bearing block at both ends on two roll shafts and connects; Regulate time, first the bolt being fixedly connected with bearing block and frame is unclamped, then by screw adjusting bolt adjust bearing block and on roll shaft spacing, then by bearing block and frame fastening.

Described governor motion can also be made up of leading screw, screw and servomotor, the bottom face of the bearing block at two roll shaft both ends is installed with screw, is equipped with the leading screw be connected with servomotor in screw.

As shown in Figure 5, the tooth pitch of the adjacent teeth on described fluted disc 12 is 0.8 ~ 2.0cm, and the degree of depth of teeth groove is between 0.3 ~ 1.0cm.

Due in actual production, varying in size of the kind difference of bark, required crushed particles, the diameter of the diameter of the diameter of the roll shaft in the present invention and length scale, fluted disc and length scale, entretoise annulaire and length scale, the number of teeth of fluted disc and gullet depth and profile of tooth all can change as required.

As shown in Figure 7, on two roll shafts, pitch wheel 7 outside can arrange a gear cover 8 and establishes within it by gear cover, can effect prevent dust, foreign material etc. enter between gear, prevent it to the damage of gear.

In addition, discharge outlet on the invention can increase by a screening mechanism, as rotary screen etc., due to the self-characteristic of bark, it can produce particulate material not of uniform size unavoidably in shattering process, bark particle after fragmentation can be carried out classification collection by size, to meet different needs by screening mechanism.

It should be noted that, the present invention, by selecting fluted disc and the entretoise annulaire of suitable material, also can be used in the fragmentation of other high rigidity materials such as ore, and range of application is comparatively wide, and crushing effect is good.
