Such a structure is configured such that the driving force is transmitted to the driving shaft 8, So that the distance of the base 11 can be adjusted.

That is, when the diameter of the drive pulverizing roller 7 and the driven pulverizing roller 8 is small, the distance adjusting bolt 27 is pulled into the base member 26 and, on the contrary, the drive pulverizing roller 7 and the driven pulverizing roller 8, The distance adjusting bolt 27 may be drawn out from the base member 26. In this case,

The driving pulverizing roller 7 and the driven pulverizing roller 8 are driven by a driving motor 13 fixed to one side of the mounting base plate 4. In the present invention, The sprocket 14 is provided on the shaft and the chain 16 is connected to the sprocket 15 provided on the motor shaft so that the drive motor 13 can be driven. The drive gear 17 is provided on the shaft of the drive crushing roller 7 opposite to the sprocket 14 and the driven gear 17 is provided on the shaft of the driven crushing roller 8 so as to correspond to the drive gear 17, 18). At this time, the driven gear 18 has a dimension larger than the diameter of the driving gear 17, and the driven pulverizing roller 8 rotates relatively slowly when the driving pulverizing roller 7 rotates at high speed by the driving motor 13. [ .

As shown in FIG. 5, the driving pulverizing roller 7 and the driven pulverizing roller 8 form crushing grooves 7a and 8a which are embedded in a lattice shape on the surface to a depth of 0.1 mm or less.

In such a configuration, when the grain is crushed, the grain may be finely crushed by a method in which the counter roller hits the grain while a part of the grain is in the crushing groove 7a (8a).

In the case of the configuration of the shaft supporting portion 11 coupled to the shaft supporting portion fixing groove 12 formed on the mounting base plate 4 so as to support the axes of the driving and crushing roller 7 and the driven crushing roller 8, And the bearing 11b is simply coupled.

To this end, as shown in the drawings, the main shaft 11b and the tolerance adjusting bearing 11c are inserted into the housing 11a to couple the shafts of the driving and driven shredding rollers 7 and 8, A screw hole 11e is formed in a direction perpendicular to the side of the input hopper 6 where the driven and driven crushing rollers 7 and 8 contact with the outer periphery of the screw hole 11c, The screw 11f is tightened so that the tolerance adjusting bearing 11c can be pushed to the side opposite to the side on which the driven and driven crushing rollers 7 and 8 abut. 11d shows a retainer.

When the shaft 11 is formed as described above, the driving and driven collision rollers 7 and 8 are pushed outward (in the direction of 'A' in the drawing) when the grain is processed, And the development is solved in advance by the tolerance adjustment bearing 11c. That is, in the case of the tolerance adjusting bearing 11c, when the adjusting screw 11f is tightened, the driving and driven crushing rollers 7 and 8 are finely moved as much as the assembly tolerance of the tolerance adjusting bearing 11c coupled to the housing 11a And the driven and driven crushing rollers 7 and 8 are maintained in a spaced state while being moved in the opposite direction and the main bearing 11b is driven to move the driven and driven crushing rollers 7 and 8 The driving and driven pulverizing rollers 7 and 8 can be prevented from moving to the center of gravity when no load is applied, thereby enabling noncontact driving.

In this case, the assembly tolerance means that the tolerance between the outer diameter of the bearing and the housing, the bearing own confinement, the bearing inner diameter and the shaft confinement.

A scraper 19, which is detachably fixed to the mounting base plate 4 in the axial direction, is provided below the high-speed rotating driving crushing roller 7. At this time, the scraper 19 is installed in a non-contact manner with the drive crushing roller 7, preferably in a direction perpendicular to the paper surface. In this configuration, when the adjusting screw provided on the shaft supporting portion 11 is tightened with the scraper 19 installed on the driving crushing roller 7, the tolerance adjusting bearing 11c coupled to the housing 11a A clearance is formed between the driving pulverization roller 7 and the scraper 19 by the assembly tolerance, so that the non-contact state can be maintained.
