Problems solved by technology
However, the rippers are fixed to the tool shaft so that they are difficult to be separated, so the number of rippers cannot be freely adjusted
In addition, since it is difficult to set the space between the rippers fixed to the tool bar, it is difficult to adjust the number of rippers or set the positions of the rippers according to the road conditions on site
When it is necessary to install a ripper in addition to the ripper and use the ripper in combination, since the ripper and the ripper are fixed structures in the prior art, it is difficult to change their structures
For this reason, the appropriate tool cannot be selected, resulting in reduced work efficiency

A construction machinery with a ripping tool is disclosed. The construction machinery with a ripping tool according to the present invention is configured by comprising a key formed in the outer surface of a tool bar attached to the rear of the vehicle body; a retainer, one side of which is coupled to the tool bar and the other side of which a ripper is attached to; and a fastening member, both ends of which are coupled to the retainer while wrapping the remaining part of the outer circumference surface of the tool bar under the state that the retainer is in contact with the tool bar, wherein a key hole engaged with the key of the tool bar is formed in the retainer.
Description
technical field [0001] The present invention relates to construction machines, and more particularly to road machines such as motor graders. Background technique [0002] Construction machines, such as motor graders, typically include a ripper or scarifier that is detachably mounted behind the vehicle body. Scarifiers and rippers are both tools used to break up asphalt, hard-pack, or other obstructions to assist in grading operations. Scarifiers and rippers are similar in function, but they are capable of being used with different sets of ground engaging implements. Ripper teeth are generally larger and have a deeper cut than ripper teeth. [0003] US Patent No. 5,040,616 discloses a handle attachment for holding a ripper. That is, the tool bar includes a plate to removably attach the ripper. In the prior art, the ripper is attached to a target surface and is usually installed by being welded on the outer circumferential surface of the excavator bucket. Since the outer ...
