Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a work vehicle, ie, a low planer, for removing old or damaged asphalt road surfaces during road repair work.

The conventional road planer scrapes off the road surface with tooth counters installed in the center of the vehicle body (-), and ejects the stripped pieces of the road surface to the side with a play ytq installed on the rear side, as shown in Figure wJ1. In addition, a heating device (DI) is installed on the front side of the car body (GL) to soften the road surface.
It has a structure that facilitates stripping of the road surface by K and prevents wear and tear on the tooth (A).

However, the above-mentioned road planer (1.
Discharge of peeled pieces due to play white C) becomes a national disaster. (cl.
l. Since the road surface is heated and softened and then removed with teeth IA), it takes time and reduces work efficiency. pl, heating device 11! 1 is heavy and expensive, and consumes a large amount of fuel.

There are drawbacks in terms of work efficiency, vehicle operation, and economics.

The present invention aims to solve the drawbacks of conventional road planers, in which the road surface is removed using teeth placed in the center of the vehicle body, and teeth placed on the rear side.
A road planer configured to eject strips of road surface to the side by means of ``, which is provided with a bracket that is raised and lowered by a cylinder of the vehicle body, and a disc cutter having a rotational drive mechanism is attached to the bracket. It is unique in that it is equipped with a cutter device that continuously cuts and strips the road surface, and then discharges the stripped pieces to the side. The object of the present invention is to provide a low V planer that improves the work efficiency of road surface removal by peeling off the road surface with teeth after making continuous parallel cuts.

The present invention has the configuration described above.

The disc cutter, which is being rotated by the lift cylinder, bites into the road surface.
oK Parallel continuous cuts can be efficiently formed, the road surface can be easily peeled off between the continuous cuts with teeth, and the peeled off pieces become approximately uniform small pieces, and furthermore, the peeled off pieces can be easily discharged with a blade.・Therefore, the work of the disc cutter, teeth, and blade becomes smooth and quick.
The road surface removal work of the entire low V planer is significantly more efficient, and energy consumption can be significantly reduced.

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

Embodiments of the present invention are shown in FIGS. 2, 3, and 4.

In the figure, nl is the vehicle body with running wheels, 1b) is the vehicle body (α)
・Tooth placed in the lower center part of the car body (C) is 1g
The play F is arranged on the rear side of the tooth U of +, and is capable of adjusting the vertical position and the inclination angle with respect to the traveling direction by a mechanism not shown in the figure. is equipped with a disc cutter device 1fi.

The disc cutter device (/1) is a bracket (5) fixed to the front of the vehicle body (-) as shown in the figure.
5), a bracket (7) that allows the front side to be raised and lowered by pivoting the plate (8) protruding from the rear @ to the sx-hte+, and the vehicle body (- )(ali
and bracket (7) side /-) (79) Bracket (7) interposed between 97 cylinders (9) for lifting and lowering, and a large number of cylinders (9) installed horizontally between the ends of brackets (7). Disc cutter blade and bracket consisting of discs (
The disk cutter 010 rotation drive mechanism consists of a check 7 (le) between a hydraulic motor 02+ and a sprocket 63041 mounted on the upper part of the disc cutter 7).

Since the illustrated embodiment has the above-described structure, the hydraulic motor 63 drives the sprocket a3 (1@) and the sprocket 7Qt.
The disc cutter (11) of the disc cutter device 1fi is rotated (at high speed) through 9, the lift cylinder (9) is extended, and the disc cutter OI is cut into the road surface through the bracket (7). When you move forward,
Each disc of the disc cutter O1 forms a continuous cut parallel to the road surface. The amount of penetration of the disc into the road surface, that is, the depth of the cut, is determined by the disc cutter! (Since the settings can be freely adjusted depending on the weight of n and the amount of extension of the lift cylinder (9), cuts in the road surface made by the disc cutter device 1fi are defined as multiple parallel cuts extending in the direction of travel of the vehicle body (-). As a result, it becomes approximately uniform and reaches the depth of the road surface removal range, allowing for efficient formation of cuts and facilitating subsequent stripping with teeth (see Fig. 5).

Next, the teeth U disposed on the rear side (center of the vehicle body) of the disc cutter device r11fi are arranged so as to be located between the respective discs of the disc cutter (11), that is, between the cuts, as shown in Fig. 3. Because of the tooth (steel tooth)
With AIK, the road surface is removed smoothly, wear and tear on the teeth is significantly reduced, and the removed pieces become small, approximately uniform pieces. Incidentally, the interval between the discs V of the above-mentioned disc cutter, that is, the interval between the cuts, is set depending on the condition of the road surface, the strength of the cutting force of the teeth 1h1, and the like.

As described above, since the pieces peeled off by the teeth U become small pieces, the peeled pieces can be smoothly discharged to the side by the player C1 disposed on the rear side.

Therefore, according to the embodiment described above, the disc cutter device U
This is because the fi cuts in the road surface can be efficiently and properly formed, and the teeth can be used to strip the road surface and the play F can be used to discharge smoothly.

When performing repair work on a paved surface, the asphalt road surface can be efficiently removed in 1 filD. In addition, unlike conventional systems, road surface heating is not required, and the vehicle can move smoothly, resulting in a significant reduction in energy consumption.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various modifications can be made without departing from the spirit of the present invention. .
