Description

[Detailed Description of the Invention] The present invention relates to a waterway shaping device for roughly digging small and medium-sized waterways and then shaping (trimming) the waterways into a predetermined shape.

Traditionally, after rough excavation was performed using a power shovel or grader, finishing excavation was performed using a grader, etc.
Due to the lack of precision, final finishing was required manually before lining, which required a great deal of manpower and time.

The present invention has been developed with the above in mind, and its configuration will be explained below based on the embodiment shown in the drawings (1).

In the figure, 1 is a frame attached to a running vehicle (not shown), and the lower part of this frame 1 has a cross-sectional shape of a waterway.
It is formed in a letter shape, and a bottom plow 2 is fixedly installed at the bottom of the plow.

The cutter 3 is placed on the inclined part of the frame 1 in order from the front side in the direction of movement.
and a screw plow 4 are provided along the slope.

The cutter 3 consists of a shaft 6 whose tip end is supported by a support frame 5 and whose base end is supported by the frame 1, a slope cutting blade 7, a shoulder cutting blade 8, and a drive motor 9. There is.

The shaft 6 is rotated in forward and reverse directions by a drive motor 9, and therefore each cutting blade 7.8 has a cutting blade so that excavation can be performed by both forward and reverse rotation.

The screw plow 4 consists of a cutting blade 11 whose tip and base ends are spirally provided on a shaft 10 supported by a frame 1, a cover 111, and a drive motor 12, and the screw plow 4 removes excavated earth and sand while excavating a slope. It is designed to sweep upwards.

A shoulder blade 13 is provided at a portion of the frame 1 facing the base end of the screw plow 4 toward the rear side.

In the above configuration, when the drive motors 9 and 12 are driven while the frame 1 is traveling, the bottom of the roughly dug waterway is scraped by the bottom plow 2.

Further, the slope surface is roughly cut by a square cutter 3, and then finished by a screw plow 4, and the earth and sand that has been cut together with this is scraped upward and discharged from the shoulder blade 13 to both sides.

The present invention is as described above, and includes a frame 1 whose lower part has a shape that follows the surface of a waterway that has been roughly dug into a roughly square shape, and which is attached to a traveling device. A bottom plow 2 provided at the lower center, a cutter 3 and a screw plow 4 provided in order from the front in the direction of travel along the slopes on both sides of the frame 1, and both sides of the frame 1 facing the base end of the screw plow 4. Since the waterway shaping device is constructed with the shoulder blade 13 provided on the shoulder blade 13, trimming, which is finishing excavation after rough excavation with a power shovel, etc., can be carried out with high precision to a predetermined dimension, and the conventional final finishing by manual labor can be performed. This makes it unnecessary and improves the efficiency of waterway creation.
