The pipe frame 47 includes pipes 47a, 47a provided above and below at a predetermined interval in parallel, and a cover frame 47b.
Each pipe 47a, 4
A side plate 47c having a flange 47a is fixed to one end of 7a. The plate frames 45a, 4 of the elevating members 45, 45' are connected to the coins 45b, 45b and the guide member 46,

Here, a long hole 45d' is formed in the protrusion 45a'' as a through hole for the rod 45d. Therefore, the plate frames 45a, 45a'' to which the screed 42 is fixed are rotatable around the rods 45d, 45d, and the elongated holes 45d' formed in the plate frame 45 are formed at the edges of the holes. allows the plate frame 45a' to move while being supported by the rod 45d.

, 49 are provided.

Hydraulic cylinders 50 and 50' are arranged between these brackets 48 and 49, with the tip of the piston rod 50a fixed to the bracket 48 and one end of the cylinder 50b fixed to the bracket 49. By the way, the lower ends of the plate frames 45a, 45a' are covered with a leveling part 42' formed by bending the front screed 42, and each plate frame 45a, 45 is spaced at equal intervals. The two guide pipes 51, 51 are connected to the rod 4.
It is installed inside in the direction perpendicular to 5d.

Within these guide pipes 51, 51 are slidably guided rods 52, 52. Flanges 52', 52' are provided at the outer ends of each rod 52, 52, and plates 52', 52' are provided with plates 52', 52'.
3 and 53 are removably fixed. Wideners 43, 43 are fixed to these plates 53, 53, and end plates 44, 44 are fixed to the tips of the wideners 43, 43. As shown in FIG. 10, a wing 44a that forms the side end R' of the road shoulder R in a diagonal shape is fixed to one lower end of the end plate 44 by a slope adjustment hinge rod 44b. A bracket 53' is provided at the center of the plates 53, 53.
Hydraulic cylinders 54, 54, each having a piston rod 54a fixed at its tip end, are disposed between the rods 52, 52. These hydraulic cylinders 54, 54 are attached via flanges 51^ to a connecting plate 51' that connects the guide pipes 51, 51. hydraulic cylinder 5

Now, in FIG. 7, the left widener 43 is shown moved to expand in the direction of the arrow, and the right widener 43 is shown moved in the direction of the arrow from the state indicated by the dotted chain line. ,43 is
For example, it is suitable for changing the leveling width of the road shoulder R, and can also be applied to road widening work.
The mounting positions of the hydraulic cylinders 54, 54, the size of the width, the width of the pipe frame 47, etc. can be changed in various ways.

By the way, as shown in FIG.
is connected to the leveling machine A side by its flange 47b, but inside the leveling machine A there is a hollow space supported by the support frame F and the holding frame F' in parallel with the pipes 47a, 47a of the pipe frame 47. Pipes 56, 56 are provided, and rods 58, 58 to which connecting portions 57 are connected are filled with iron in these hollow pipes 56, 56,
A bracket 57a is fixed to the center of the connecting plate 57.

A hydraulic cylinder 60 is disposed between the hollow pipes 56, 56, one end of the hydraulic cylinder 60 is fixed to a bracket 60a fixed to the holding frame F', and the tip of the piston rod 60' of the hydraulic cylinder 60 is It is detachably fixed to the bracket 57a by a pin 61. The pipe frame 47 is removably fixedly connected to the connection plate 57 by screws, bolts, etc. Therefore, when removing the leveling device B from the leveling machine A, it is only necessary to remove the screws, bolts, etc. connecting the flange 47b of the pipe 47a of the pipe frame 47 and the connection plate 57, and the leveling device B is very easy to assemble and transport.

To explain the operation of the leveling device B described above in detail according to the leveling work process, first, the right side of the leveling device B is positioned close to the side edge of the road surface K, and the leveling device A A dump truck (not shown) is moved backward to assist the stopper roller 24 of the front frame 18, and the leveled material is dropped into the hopper 3.

After dropping, the belt conveyor 4 located below the hopper 3 is operated to distribute the leveling material to the required road shoulder ground, and at the same time, the leveling machine A is slowly moved. By the way, a general motorway has a linear shape as shown in FIG. 12 or FIG. 13.

If the road shoulder base R has a bend t on the road shoulder as shown in FIG. 13, the leveling machine A must tilt the screed 42 of its leveling device B. . Since the leveling machine A levels the road shoulder R while traveling on the main road S, it uses an appropriate detection means, such as a slow A slope controller (not shown) is attached to the screed 42 and communicated with the hydraulic cylinder 50'. Accordingly, the screed 42 is inclined as shown by the two-dot chain line in FIG. 11 so that the hydraulic cylinder 50' is lowered according to the data detected by the slope controller. In other words? Since the plate frame 45a' is rotated through the elongated hole 45 of the plate frame 45a' of the elevating member 45' with the rod 45d as the supporting axis, the screed 42 is tilted as a result of this rotation. In addition, an appropriate detection means such as a grade controller (not shown) is installed in the leveling device B to maintain a required leveling thickness with respect to the road surface K. It is connected to the hydraulic cylinder 50 of device B, and operates the hydraulic cylinder 50 in accordance with the detected value to maintain the screed 42 constant so that the leveling thickness for the road surface x is maintained constant.

As described above, the leveling device B uses the detection means to form the leveling material to a required leveling thickness, and also widens the width of the shoulder by using the horizontally movable widener 4 connected to the screed 42.
3.

In the aforementioned leveling width widening work, the rods 58, 58 are moved to the left by driving the hydraulic cylinder 60 installed in the leveling machine A shown in FIG. 10 depending on the width of the road shoulder. What is necessary is to move the sardine together with the widener and make various changes.
Note that the above-mentioned automatic adjustment of the leveling thickness and width can of course be performed by remote control from outside the machine. Furthermore, it goes without saying that the drive mechanism is not necessarily limited to only a hydraulic drive mechanism, and other means may be used without departing from the gist of the present invention. As is clear from the above description, the leveling machine of the present invention has a drive mechanism installed on the side of a traveling device that is provided with a drive mechanism, a hopper, and a belt conveyor. A leveling device consisting of a screed that is movable up and down and tiltable to maintain the leveling surface, and a widener and an end plate that are movable in a direction perpendicular to the running direction to maintain the required leveling width. Since it is equipped with a removable machine, it automatically adjusts the extremely good flatness and spreadability of the road shoulder and other areas to be leveled, allowing the work to proceed without interruption, resulting in extremely high work efficiency. The operation is simple and easy, and the construction ability is as follows: the hopper has a large material supply capacity and has extremely good dumping efficiency, and the belt conveyor allows material distribution to be determined arbitrarily, allowing continuous construction. The leveling machine itself is hydraulically controlled and can be operated by one person, which saves labor and has the advantage of significantly improving the quality of construction work.
