That is, by rotating the augers 99, 99 by the drive motor 95, the scraping material is scraped toward the center portion in the width direction of the succeeding vehicle body 2, and the scraping material moves inside the casing 81 in the endless chain.
It is scooped up by the transport bar 91a that rotates from 91,91,
From the opening at the rear end of the casing 81 to the weighing feeder device 11
Transported to 0.

Then, the new mixture material and the scraping material which have been conveyed as described above, while being conveyed by the weighing feeder devices 117, 110 operated by the drive motors 122, 115, respectively, the respective weights are measured by the load cells for measuring 120, 113, It is supplied to the mixer device 135.

Then, after the mixer device 135 mixes the new mixture material and the scraping material, the mixed material is spread out by the sprinkling device 140.
The mixed material is transferred in the width direction of the succeeding vehicle body 2 and uniformly sprayed on the road surface by the rotation of the screw 141 of the sprinkling device 140. The height of the screwing device 140 from the road surface of the screw 141 is adjusted by expanding and contracting the piston rod 143a of the cylinder 143.

Next, the composite material scattered on the road surface is evenly spread by the above-mentioned leveling device 150 as follows. That is,
In advance, an operator may use the piston rods 152a of the cylinders 152,152,
152a is extended and the leveling device 150 is lowered on the road surface. At this time, lumber or the like is placed between the leveling device 150 and the road surface so that the target leveling thickness is obtained. After starting the leveling, the left screed 153 and the right screed 154 are connected to the following vehicle body 2
During the work of adjusting the leveling width by expanding or contracting in the width direction of each of the screeds, the vibrators of the screeds 153 and 154 are activated to vibrate the screeds 153 and 154, and the screed plates 155 and 155 on the lower surface of the screeds 153 and 154 mix on the road. The material is pressed flat and leveled. The amount of crown on the road surface is adjusted by moving the brackets 158 and 159, which are fixed to the frames 156 and 157 supporting the screeds 153 and 154, toward and away from each other by the turnbuckle 160.

In the road surface reclaiming method, the scraped and loosened material may be extracted to the side of the road surface. In this case, the screw 75 in the casing 73 of the extraction device 70 provided at the forefront of the succeeding vehicle body 2 is used. Is rotated, and the screw 75 transfers the scraping material to the side of the road surface and removes it. The on-road cutting mixer having the above-described structure is equipped with various devices required for the on-road surface layer reconstructing method by using the preceding vehicle body 1 and the following vehicle body 2
A hopper device 3 that receives the new mixture on the preceding vehicle body 1, and a feeder device 10 that conveys the new mixture material from the hopper device 3 to the rear portion of the preceding vehicle body 1.
And a cutter device 32 for scraping and unraveling the paved road surface, and a transfer feeder device 50 for transferring the new mixture carried by the feeder device 10 to the succeeding vehicle body 2, while the succeeding vehicle body 2 is provided.
Pick-up feeder 80 for scooping up the scraped material
And a weighing feeder device that weighs and conveys the scraped material
110, a weighing feeder device 117 for weighing and transporting the new composite material, a mixer device 135 for mixing the scraping and loosening material transported by these weighing feeder devices 110, 117 and the new composite material, and a mixer device 135 for mixing A sprinkling device 140 that scatters the mixed material thus spread onto the road surface, and a leveling device 150 that spreads and spreads the mixed material spread out are provided.

Therefore, it is possible to pave the road surface by running the preceding vehicle body 1 and the following vehicle body 2 in tandem, and at the time of transportation, the preceding vehicle body 1 and the following vehicle body 2 can be separately transported. Is easier than before.

Further, in the case where all the various devices are mounted on a single traveling vehicle body as in the conventional case, the upper limit of the weight is determined due to transportation restrictions, and therefore each device has to be downsized, resulting in insufficient processing capacity. However, in the case of the road cutting mixer of the above-mentioned embodiment, various devices are reasonably distributed and mounted on the preceding vehicle body 1 and the following vehicle body 2, so that the device itself can be made larger than the conventional one. Therefore, it is possible to improve the throughput and reliability of various devices and improve the productivity. By the way, the conventional processing capacity was about 40 to 70 tons / h, but in the case of the above road cutting mixer, it was improved to 120 tons / h.

Further, the road cutting mixer is separated into the preceding vehicle body 1 and the following vehicle body 2, and further, the transfer feeder device 50 for conveying the new mixture material to the following vehicle body 2 is provided at the rear portion of the preceding vehicle body 1, so that on the road surface In addition to being able to make small turns, it is possible to easily perform construction on sharp curves, expanding the applicable range of the road surface reclaiming method.

In addition, the leading vehicle body 1 and the trailing vehicle body 2 can be separately used according to the application, and various devices are dispersed in the leading vehicle body 1 and the trailing vehicle body 2 for maintenance and inspection. A large space can be taken and maintenance can be performed more easily than before.

[Advantages of the Invention] As described above, according to the on-road cutting mixer of the present invention, the leading vehicle body and the trailing vehicle body can be separately transported at the time of transportation, which facilitates transportation as compared with the prior art. .

Further, in the case where all the various devices are mounted on a single traveling vehicle body as in the conventional case, the upper limit of the weight is determined due to transportation restrictions, so that the processing capacity of each device becomes insufficient. In the case of a mixing machine, various devices are reasonably distributed and mounted on the preceding vehicle body and the following vehicle body, so that the device itself can be upsized as compared with the conventional one, and thus the processing capacity and reliability of various devices can be improved. Can be raised to improve productivity.

Furthermore, because the road cutting mixer is separated into the preceding vehicle and the following vehicle, and a transfer feeder device is installed between the preceding vehicle and the following vehicle to convey the new mixture from the preceding vehicle to the following vehicle. In addition to making it possible to make small turns on the top, it is possible to easily perform construction on sharp curves, expanding the applicable range of the road surface reclaiming method.

In addition, it is possible to separately use the preceding vehicle body and the following vehicle body separately depending on the application, and since various devices are distributed between the preceding vehicle body and the following vehicle body, a large space for maintenance and inspection is taken. Therefore, maintenance can be easily performed.
