Description

[Detailed Description of the Invention] The present invention relates to a stabilizer working device used for regenerating asphalt roads and improving roadbeds and roadbeds.

Conventionally, in this type of work equipment, when attaching the work equipment main body to the guide portion a on the vehicle body side, the fitting holes e of the side frames C and center frame b of the work equipment main body are used.
, by inserting slide g into guide section a and f.

Moreover, disassembly was performed in the reverse order (see Figure 1, Ln, solid line arrows indicate disassembly, dotted line arrows indicate assembly).

However, this conventional type had poor assembly workability.

The present invention was developed in view of the above circumstances, and its purpose is to allow the main body of the work machine to be removed from the slide guide with a simple operation, and to attach the main body to the slide guide by the reverse operation. To provide a working machine device for a stabilizer, which can improve assembly workability.

Hereinafter, the present invention will be explained with reference to the drawings.

In the drawing, 1 is a vehicle body having a power source, a traveling device, etc., and 2
is a working machine that performs crushing and mixing.

This working machine 2 is connected to the vehicle body 1 at the front end side by a ball joint 3 and a hydraulic cylinder 4, and has a structure in which the depth of crushing and mixing can be arbitrarily selected by expanding and contracting the hydraulic cylinder 4.

The work machine 2 includes a side frame 6, and a shaft portion 8a of a rotary disk 8 is attached to a support portion 6a of the side frame 6.
is supported via a bearing 17.

A hydraulic motor 7 is provided on the side frame 6, and a sprocket on the shaft of the hydraulic motor 7 and the rotary disk 8
A chain is attached to the sprocket 20 of the shaft portion 8a.

A crushing bit 9 is attached to the tip of the rotary disk 8.

The working machine 2 is provided with a rotor cover 11 that covers the rotary disk 8 for the purpose of preventing fragments from scattering, safety, soundproofing, dustproofing, and the like.

The rotor cover 11 has a floating structure so that it is always in contact with the upper surface of the roadbed during work without being affected by changes in crushing or mixing depth.

A center frame 12 is interposed between the side frames 6, and a slide guide 13 is removably provided on the center frame 12.

Fitting holes 1 are provided in the side frame 6 and center frame 12.
4.15, and fitting portions 16 are formed at both ends of the slide guide 13.

A holder 22 is fitted into the fitting portion 16 from the fitting hole 14.15, and the holder 22 and the side frame 6 are fastened with bolts 23, and the holder 22 and the slide guide 13 are It is fastened with bolts 24.

The slide guide 13 is a guide portion 2 connected to the vehicle body 1 side.
5, and is slidably provided in the center frame 12. The side frame 6 and rotary disk 8 are designed to be movable left and right.

Then, by removing the bolts 23 and 24 and removing the holder 22 from the fitting holes 14 and 15 and the fitting part 16 as shown by the solid arrow in FIG. Cover 11. The work machine main body A with the rotary disk 8 still assembled can be removed from the slide guide 13.

The working machine main body A can be assembled to the slide guide 13 by the reverse order of operations, that is, by the operation indicated by the dotted arrow in FIG.

The present invention has been described in detail above, and fitting holes 14 and 15 are provided in the side frames 6 and center frame 12, which are the constituent members of the work machine main body A, respectively, and the guide portions 25 connected to the vehicle body 1 are provided with fitting holes 14 and 15, respectively. Fitting portions 16 are provided on both end surfaces of the slide guide 13 provided so as to be slidable, and the fitting portions 16 are provided in the fitting holes 1.
4. Fit the holder 22 from 15 to the fitting part 16, tighten the holder 22 and the side frame 6 with bolts, and tighten the holder 22 and slide guide 13 with bolts. Remove the bolts and remove the holder 22. The work machine main body A can be removed from the slide guide 13 by simply pulling it out, and the work machine main body A can be attached to the slide 13 by performing the reverse operation, improving the ease of assembly.
