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, when using this stabilizer work machine,
Particularly when crushing asphalt roads, if large fragments remain, not only will it impede subsequent work, but the required strength of the roadbed may not be obtained.

The present invention was developed in view of the above circumstances, and its purpose is to make it possible to reduce the size of crushed pieces to below a certain limit, and to also arbitrarily change the gap through which the crushed pieces pass. can be done.

The purpose of the present invention is to provide a stabilizer work machine device.

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 chain 21 is connected to a sprocket 19 on the shaft of the hydraulic motor 7 and a sprocket 20 on the shaft portion 8a of the rotary disk 8.

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 scattering of crushed pieces, safety, soundproofing, and dustproofing.

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 crushing or changes in mixing depth.

A secondary crushing breaker 12 is disposed between the crushing bit 9 and the rotor cover 11.

A pin member 17 is provided at the upper end of this secondary crushing breaker 12.
is attached in a penetrating state, and this pin member 17 is inserted into a triangular bow-shaped portion 10 formed in the side frame 6.

Further, the secondary crushing breaker 12 movably passes through a guide portion 21 provided on the rotor cover 11.

Mounting brackets 22 and 23 are fixed to the rotor cover 11, and the other end of the link 14 on one of the mounting brackets 22 is connected to one end of the other link 13 via a pin 25. The other end of the link 13 is connected to the pin member 1
It is joined to 7.

The base end of the actuating cylinder 15 is attached to the other mounting bracket 23 with a pin 26, and the rod 27 of the actuating cylinder 15 is joined to the pin 25 for joining the link 13.14, and these actuate the movement adjustment mechanism. It constitutes A.

Then, the rotary disk 8 is rotated by the drive of the hydraulic motor 7, and the roadbed is crushed by the crushing bit 9 of the rotary disk 8.

These crushed pieces pass through the gap between the crushing bit 9 and the rotor cover 11 by the rotation of the rotary disk 8 and are carried to the rear part 5, but if this continues, there is a possibility that the size of the crushed pieces will exceed the target value. .

However, since there is a secondary crushing breaker 12 between the crushing bit 9 and the rotor cover 11 that has a certain slit 12a in the longitudinal direction, if a large crushed piece larger than a certain limit is generated, the secondary crushing is done here. It is brought to the rear part 5 after being brought down to a size below a certain limit.

The secondary crushing breaker 12 moves along the guide portion 21 via links 13, 14 by the expansion and contraction of the operating cylinder 15, and the gap between the secondary crushing breaker 12 and the crushing bit 9 is set arbitrarily.

The movement of the secondary crushing breaker 12 is regulated by the pin member 17 inserted into the thank-you part 10 and the guide part 21, regardless of the relative position of the rotary disk 8 and rotor cover 11. The secondary crushing breaker 12 and the crushing bit 9 are designed not to interfere with each other.

The present invention has been described in detail above, and the guide portion 21 is provided on the rotor cover 11 arranged to cover the rotary disk 8 equipped with the crushing bit 9, and the secondary crushing breaker 12 is attached to the guide portion 21. A triangular bow part 10 is formed on the side frame 6 which is movably provided on the disk 8 side and supports the rotary disk 8, and a pin 17 provided at the upper end of the secondary crushing breaker 12 is attached to the bow part 10.
A mounting bracket 22 is provided on the rotor cover 11, one end of the link 14 is connected to the mounting bracket 22, and the other end of the link 14 is connected to one end of the link 13 with a pin 25. This stabilizer working machine device is characterized in that one end of the actuating cylinder 15 is connected to the pin 17, and the other end of the operating cylinder 15, one end of which is swingably attached to the rotor cover 11, is connected to the pin 25.

Therefore, the size of the crushed pieces can be reduced to below a certain limit by the secondary crushing breaker, and the secondary crushing breaker 12 is attached to the guide part 21 via the link 14.13 by actuating the actuating cylinder 15. The gap between the secondary crushing breaker 12 and the crushing bit 9 can be arbitrarily changed by moving along the secondary crushing breaker 12 and the crushing bit 9.
