The present invention is to provide a kind of blade assembly of drum chipper to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of blade assembly of drum chipper, including fly cutter seat, blade and pressure
Block, the blade and briquetting are fixed on fly cutter seat by screw, and a side pressure of briquetting is touched on blade；
Axis hole is provided with the center of the fly cutter seat, four arc chip troughs and four are provided with the periphery of fly cutter seat
Blade installation slot, four blade installation slots are correspondingly placed in the side of four arc chip troughs；The blade installation slot is rectangular-shaped；
Some mounting holes are provided with a right-angle side of blade installation slot, are set on another right-angle side with some positioning holes, in each installation
Adapter sleeve is fixedly connected with hole, blade is fixed on adapter sleeve by screw, and one end of blade is plugged in positioning hole；
The cross section of the briquetting is arc-shaped, and one end of briquetting is fixed on adapter sleeve by screw, other end positioning
In on the right-angle side of blade installation slot；
The right-angle side of the blade installation slot is provided with positioning step, is provided with and the positioning step phase on the end face of briquetting
The locating slot of adaptation.
Further, alignment pin is welded with the blade, the alignment pin is plugged in positioning hole.
Further, the center position of the adapter sleeve is provided with tapped through hole, and adapter sleeve top side wall stretches out simultaneously
Form the positioning side of platform-like.
Further, the adapter sleeve is fixed in the mounting hole of blade installation slot by screw.
Further, the adapter sleeve is made of 40Cr steel.
The present invention has the advantages that：
1) alignment pin in the present invention on briquetting and blade can ensure the mounting stability of blade so that blade connection can
Lean on, loose phenomenon will not occur；
2) adapter sleeve of the present invention can effectively protect fly cutter seat, substantially increase the service life of fly cutter seat, improve material
Expect utilization rate, reduce use cost.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 and Fig. 3 is the broken section enlarged drawing of the present invention.
Fig. 4 is the structure chart of adapter sleeve in the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, the present invention discloses a kind of blade assembly of drum chipper, including fly cutter seat 5, the and of blade 8
Briquetting 9, blade 8 and briquetting 9 are fixed on fly cutter seat 5 by screw, and a side pressure of briquetting 9 is touched on blade 8, the other end
It is positioned on fly cutter seat 5.
Axis hole 50 is provided with the center of fly cutter seat 5, the periphery of fly cutter seat 5 is provided with four arc chip troughs 51 and four
Individual blade installation slot 52, the corresponding side for being placed in four arc chip troughs 51 of four blade installation slots 52.
Blade installation slot 52 is rectangular-shaped, and some mounting holes, Ling Yizhi are provided with a right-angle side of blade installation slot 52
Set on the arm of angle with some positioning holes 55, adapter sleeve 6 is fixedly connected with each mounting hole, blade 8 is fixed on company by screw
In female connector 6, and the knife back of blade 8 is plugged in positioning hole 55, and the cutting edge of blade 8 stretches in the upper end of arc chip trough 51.
The cross section of briquetting 9 is arc-shaped, and one end of briquetting 9 is fixed on adapter sleeve 6 by screw, and the other end is positioned at
On the right-angle side of blade installation slot 52；
For ease of briquetting 9 is positioned in blade installation slot 52, positioning step is provided with the right-angle side of blade installation slot 52
520, the locating slot being adapted with the positioning step 520 is provided with the end face of briquetting 9.
For ease of blade 8 is positioned in blade installation slot 52, some alignment pins 81 are welded with the knife back of blade 8,
Alignment pin 81 is plugged in positioning hole 55.
