Description

[Detailed Description of the Invention] The present invention relates to the structure of a cutting blade of a stabilizer that simultaneously crushes, mixes, and regenerates the surface layer of asphalt pavement, roadbed, and roadbed of roads, airports, parking lots, etc.

As shown in FIG. 1, a conventional stabilizer has mounting holes 1a drilled at appropriate intervals around a rotor 1 that is rotationally driven.
A large number of cutting blades 2 are arranged by fitting the insertion rod 2a of the cutting blade 2 into the mounting hole 1a, and as shown in FIG. A chip 3 made of an alloy is integrally attached by welding or the like.

However, since the above conventional insertion rod 2a was simply formed into a tapered shape and was inserted into the mounting hole 1a by its wedge action, it could easily fall off due to some kind of impact, and the crushing and mixing effects would be reduced. Not only is this impossible, but the corner portions 3a at both ends of the chip are severely worn and damaged, resulting in many inconveniences such as having to interrupt the work.

This invention was developed to solve the above-mentioned disadvantages of conventional cutting blades, and its purpose is to prevent the cutting blade from easily coming off from the rotor mounting hole, and to be highly durable and to improve work efficiency. Provide cutting blades for stabilizer.

An embodiment of the present invention will be described below with reference to the drawings.

In Figure 3, 4 is the cutting blade body, 4b is the insertion rod, and 4c
is a cut groove.

The insertion rod 4b is formed into a tapered shape, and is adapted to be inserted into a mounting hole of the rotor and fixed by a wedge action.

Cut grooves 4c are cut on both sides of the insertion rod 4b, and the insertion rod 4b is installed by inserting a key (not shown) from the outside of the mounting portion having a mounting hole in the cut grooves 4c. It is made so that it is difficult to fall through the hole.

A tip 6 made of cemented carbide is provided on the cutting side of the cutting blade body 4.
are integrally welded together.

A suction recess 6a is formed in the center of the chip 6 to improve its penetration into the roadbed.

A chevron-shaped protrusion 6b is formed at the tip ends on both sides of the suction recess 6a to withstand wear due to long-term use.

As described above, in this invention, the insertion rod is tapered and grooves are carved on both sides of the rod, and the key is inserted into the grooves, so there is no need to worry about the cutting blade easily falling out. Moreover, since a suction recess is formed in the center of the tip, it penetrates easily into the roadbed.Furthermore, both ends of the tip are formed in a chevron-shaped protrusion, so it can withstand wear and tear from long-term use. This has the advantage of increased durability and improved work efficiency.

Claims (1)

[Scope of utility model registration request] A chip made of cemented carbide is integrally folded onto the cutting surface of the cutting blade body, which has an extended insertion rod that is inserted into a mounting hole formed around the rotor, and the insertion rod has a tapered shape. What is claimed is: 1. A cutting blade for a stabilizer, characterized in that a cutting groove is formed on both sides of the cutting blade, a suction recess is formed in the center of the tip, and a chevron-shaped protrusion is formed in both ends.
