Description
Technical Field
The utility model belongs to the technical field of rubbing crusher technique and specifically relates to an adjustable rubbing crusher blade group.
Background
The crusher is a common mechanical device in production and life, and the blade assembly is a core component of the crusher. When the crusher crushes large-size hard materials, the cutting edge dislocation angle of adjacent cutter heads on the same cutter shaft of the blade group influences the twisting speed of the materials, and further influences the crushing efficiency of the crusher. In the prior art, the dislocation angle of the cutting edges of adjacent cutter heads on the same cutter shaft of the crusher blade group is fixed, and the blade group cannot be adjusted according to different crushed materials, so that the crushing efficiency of the crusher is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defects that exist among the prior art, the utility model provides an adjustable rubbing crusher blade group.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an adjustable rubbing crusher blade group, includes arbor, blade disc and blade disc separator are installed in the arbor in turn, its characterized in that: the cross section of the cutter shaft is regular n-shaped and is matched with the cutter head and the middle shaft hole of the cutter head isolating piece, and n is more than or equal to 5; the thickness of the cutter head isolating piece is not less than that of the cutter head; the cutter head radially stretches out m cutting edges at equal angles, m is larger than n and is not an integral multiple of n, and the rear part of each cutting edge, namely the back of each cutting edge, cuts into the outer edge of the cutter head.
In the above adjustable crusher blade set, the surface of the blade back is provided with transverse saw teeth.
The utility model discloses in, the contrast is installed two adjacent blade discs on same arbor, blade disc forward rotation a week is that well shaft hole rotates n face forward, blade disc outer fringe forward rotation m cutting edges, every forward rotation well shaft hole n limit's of blade disc 1 face promptly, blade disc outer fringe rotates a m/n cutting edge forward, because the cutting edge is the same at angular distribution such as blade disc outer fringe and every cutting edge, be equivalent to the every forward rotation well shaft hole n limit's of blade disc 1 face promptly, blade disc outer fringe forward rotation (m-n)/n cutting edge.
The utility model has the advantages that: the utility model discloses according to the size characteristics adjustment by crushing object, through the cutting edge dislocation angle that changes the blade disc adjacent blade disc on the same arbor of the installation angular adjustment of blade disc on the arbor, improve the quilt of object in rubbing crusher and twist into speed, improve crushing efficiency.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of a blade set of the present invention;
fig. 2 is a schematic view of the sequential rotation effect of the cutter head of the present invention.
In the figure, 1, a cutter shaft, 2, a cutter head, 3, a cutter head spacer and 4, a cutting edge.
Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the following provides a further description of the present invention with reference to the accompanying drawings, and obviously, the following described drawings are only one embodiment of the present invention, and for those skilled in the art, other embodiments can be obtained according to the drawings and the embodiment without any creative work, and all belong to the protection scope of the present invention.
An adjustable pulverizer blade group comprises a cutter shaft 1, a cutter disc and a cutter disc spacer 3, wherein the cutter disc 2 and the cutter disc spacer 3 are alternately arranged on the cutter shaft 1, and the cross section of the cutter 1 is a regular 6-edge shape and is matched with a middle shaft hole of the cutter disc 2 and the cutter disc spacer 3; the thickness of the cutter head isolating piece 3 is not less than that of the cutter head 2; the cutter head 2 extends 7 cutting edges 4 at equal angles along the radial direction, and the rear parts of the cutting edges 4, namely the back of the cutter, cut into the outer edge of the cutter head; the surface of the knife back is provided with transverse sawteeth.
The utility model discloses in, contrast two adjacent blade discs 2 of installing on same arbor 1, blade disc 2 is rotatory a week forward and is that the centre bore is rotatory 6 faces forward, blade disc 2 outer fringe is rotatory 7 cutting edges 4 forward, namely every 1 face of rotatory centre bore 6 limit forward of blade disc 2, blade disc 2 outer fringe is rotatory 7/6 cutting edges 4 forward, because cutting edges 4 are equal angular distribution and every cutting edge 4 is the same in blade disc 2 outer fringe, be equivalent to 1 face of every rotatory centre bore 6 limit forward of blade disc 2, blade disc 2 outer fringe is rotatory 1/6 cutting edges 4 forward, the dislocation angle of cutting edges 4 on two adjacent blade discs 2 on the same arbor 1 can be adjusted relatively accurately to this method, improve the quilt of object in the rubbing crusher and twist into speed, improve crushing efficiency.
As shown in fig. 1 and 2, the position of the blade 4 is changed from 1 surface of the polygon of the central shaft hole 6 to the right.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
