Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine for spreading a mastic mixture in a thin layer for use in spreading a mastic mixture for repair pavement in a thin layer on, for example, old paved roads. be.

When spreading the mastic mixture over old pavement, etc., it is conceivable to use an asphalt finisher, but with conventional asphalt finishers, it is difficult to spread the mastic mixture in a thin layer, e.g. It is impossible to break.

The object of the present invention is to provide a thin-layer carpeting machine capable of uniformly spreading a mastic mixture in a thin layer.

Next, the present invention will be explained in detail using illustrated examples.

(1) Page 1 shows an embodiment of the present invention.

An upper hot arm 2 extending in the left-right direction is fixed to the rear of a vehicle 1 having a self-propelled drive device via a bracket 8,
In addition, a rotating screw 4 for dispersion extending in the left-right direction is installed in the upper hopper 92, and a drive device (not shown) for driving the rotating screw 4 is fixed to the side of the upper hopper 2. .

Further, a gate 5 having an arcuate cross section for opening and closing is provided at the lower exit of the upper dart 2', and a support plate 9 fixed to both left and right ends of the dart 5 is rotatable to the upper hatch 2. attached, the gate 5 and the bracket 8 [ff

The lower hopper 5 extending in the left-right direction at the lower part of the upper hopper 2 is connected to the left and right cylinders of the vehicle 1.
It is fixed to the rear i portion of the disposed support arm 11.

The front end of the support arm 11 is connected to the vehicle 1.
A hydraulic cylinder 1 is pivotally connected to the support arm 112, and the middle part of the support arm 11 and the vehicle 1 are connected to a hydraulic cylinder 1 for lifting and lowering the support arm.
5ft: Connected through the IJ-)'6. is fixed, and a burner 14 for heating the screed 6 is attached to the top of the screed 6.

A plurality of guide f members 15 each made of a vertical tube are fixed to the left and right sides of the lower hopper 5 at intervals in the front-rear direction, and the skis 16 arranged at the bottom of the left and right sides of the lower hopper 3 include The lower part of the support rod 17 slidably fitted into the guide 9 member 15 and the upper part of the fixed support rods 17 adjacent in the front and back direction are fixed to a connecting member 18, and the intermediate part of the connecting member 18 is fixed. 19.
An engaging member 21 to be engaged with the upper and lower surfaces of the intermediate connecting member 18 of the adjusting operation rod 20 having a male thread at the lower part is fixed, and a lower hole/mother 5 is attached to the lower male screw of the adjusting operation rod 20. -The above /% 7
When the adjustment operation rod 20 is rotated in one direction or the other by the pull lever 19, the ski 16 is moved upwardly relative to the lower hollow/base 5 via the connecting member 18 and the support rod 17 by the adjustment operation rod 20-. Alternatively, the screed 6 is moved downward so that the height of the lower surface of the screed 6 from the lower surface of the ski 16 is adjusted.

A forced agitation feed member 7 extending in the left and right direction is rotatably installed at the lower part of the lower hopper 5, and a forced agitation feed member 7t-rotating drive device (not shown) is installed in the lower hopper 5. fC) is fixed, and the forced agitation feeding member 7 includes a horizontal rod 24, a plurality of ρ blades 25 arranged in a spiral around the rod, and the like. Feather 25
a mounting screw 26 having one end fixed to an intermediate portion thereof and the other end screwed to the rod 24;
'f: Consists of a lock nut 27 that is fixed to the rod body 24.

A receiver 28 is provided at the front of the vehicle 1 to receive the mastic mixture from a dump truck or a pickup truck, and a transfer pipe 29 and a transfer tube 29 housed therein are rotated by a drive device. The front end of the transfer pipe 29 in the screw feeder 51 consisting of a screw 50 is connected to the outlet of the hot-receiving hole 28, and the upper hopper is connected to the discharge port 52 at the rear end of the transfer pipe 29. Upper VC arrangement I (equipped.

When using the thin layer laying machine of the above embodiment to spread a thin layer of the mastic mixture for guidance paving on the road surface of an old road, etc., the hydraulic pressure of the hydraulic cylinder 15 for raising and lowering the support arm is With the skis 16 released and the skis 16 placed on the road surface 55, the vehicle 1 is running at a low speed, and the mastic mixture that has been supplied to the upper layer #2 from the receiving hole and the screw feeder 51 from the 2nd day is as follows. It is evenly spread in the left and right direction by the rotating screw 4 for spreading, and then the hydraulic cylinder 10
The gate 5 is opened, and the mastic mixture in the upper hopper f2173 is dropped and supplied to the lower hopper 5P'3.
The mastic mixture supplied into the lower hollow 96 is stirred by the forced stirring feed member 7 [and is forcibly fed into the gap H between the screed 6 and the road surface 35, so that the mastic mixture is forced to move at low speeds of the vehicle 1. Accordingly, the mastic mixture is spread on the road surface 55 in a thin layer (with a thickness of approximately 511I11 or less) to a uniform thickness. in this case.

By adjusting the relative vertical position between the ski 1.6 sliding on the road surface 55 and the lower hopper 5.

The spreading thickness of the mastic mixture can be adjusted.

In addition, when transporting the machine with a thin layer of carpet, use hydraulic cylinder 1.
5 is shortened, and the rear end of the support arm 11, the lower hopper 5 attached thereto, and the portion supported by the lower hopper are moved upward.

In the case of the above embodiment, the burner 14 burns the screed (l
Heating makes it possible to apply thin layers of mastic mixtures with high efficiency.

In the case of carrying out the present invention, as the forced feeding member 7, a one-turn screw FCFL, a rod with a large number of protrusions for stirring and feeding fixed around the rod, or a stirring and feeding member 7 may be used. Any other type may be used as long as it has built-in functionality.

According to the present invention, the mastic mixture supplied into the upper hopper 2 extending in the left-right direction is spread in the left-right direction by the spreading rotary screw 4 extending in the left-right direction in the upper hollow. , is supplied to the lower hopper 5,
The mastic mixture supplied in a diffused state into the lower hollow groove 5 is stirred by a forced stirring feed member 7 rotated by a drive device and is spread into the gap H between the screed 6 and the road surface 5 groove. Since the mastic mixture is forcibly fed, the mastic mixture can be applied to the road surface filter 6 in a thin layer with a uniform thickness.
