Description

[Detailed description of the invention] This invention relates to a rotary cutter device used for finishing work on slopes and cutting ground surfaces.

Conventionally, when creating a slope, finishing work is done manually or using a bucket.
However, manual work has the drawback of poor work efficiency, and tools such as buckets leave claw marks on the slope surface, making it impossible to perform highly accurate finishing work.

This invention was made with the aim of eliminating such drawbacks, and is intended to provide a rotary cutter device that can finish slopes and cut ground surfaces efficiently and with high precision.

This invention will be described in detail below with reference to an illustrated embodiment. In the figure, 1 is the main body of this device, which has a rectangular shape, and a rotary drive source 2 such as a hydraulic motor is installed in the center of the top surface, and the main body 1 is attached to a working machine 3, which will be described later, on both sides. A bracket 4 is provided for this purpose. Rotating shaft 2a of the rotary drive source 2
penetrates the main body 1 and protrudes to the lower side of the main body 1, and a cutter mounting member 5 is detachably attached to the tip with a nut 7. The cutter attachment member 5 has a disk shape, and is adapted to be rotated in a fixed direction by the rotational drive source 2. A plurality of, for example, three cutters 6 are mounted on the lower surface of the cutter attachment member 5. are arranged in a radial manner.

Since this invention has been described in detail above, during work, one bracket 4 is pivotally attached to the tip of an arm 3a constituting a working machine 3 of a construction machine (not shown) by a pin 8, and the other bracket 4 is It is sufficient to connect the tip of the hydraulic cylinder 3b provided along the arm 3a via the link 3c, and connect the pipe line 9 piped from the hydraulic power source of the construction machine to the rotary drive source 2. In this state, the rotary drive source 2, the main body 1 may be moved along the slope to be finished while rotating the cutter attachment member 5. As a result, the slope can be continuously cut with the cutter 6 attached to the cutter attachment member 5, so finishing work on the slope can be done quickly and efficiently, and the finishing accuracy can be improved compared to when it was done with a bucket or the like. significantly improved compared to . In addition, by selecting the material of the cutter 6, you can not only finish slopes, but also cut road surfaces, concrete slabs, asphalt surfaces, or rock surfaces to create a flat surface, or cut holes of desired depth. It has a wide range of uses, and since the cutter attachment member 5 can be easily removed from the main body 1, the cutter 6 can be easily replaced.
