Japanese Unexamined Patent Publication No. 2016-47989 JP 2017-14755 A

  However, the snow removal machine described in Patent Document 1 described above is a machine that removes snow on an orbit, and snow ice and ice that have solidified snow on the orbit cannot be removed.

  Further, even with the ice cutting plate of the road-rail snowblower described in Patent Document 2, it may be possible to scrape off the snow and ice attached to the rail surface, but it is fixed to the bracket. However, since it is an ice cutting plate for scraping off the snow and ice adhering to the rail surface, there is a problem that the ice on the track between the rails and outside the rail, on the railroad crossing, and the surrounding ice cannot be removed. .

  Therefore, the present invention has been made paying attention to such problems, and not only the ice adhering to the rail surface, but also on the track and railroad crossing between the rails and the outside of the rail, as well as the surroundings. An object of the present invention is to provide a backhoe ice cutter capable of cutting ice.

In order to solve the above-mentioned problems, a backhoe ice cutter according to the present invention is connected to the tip of an arm of a backhoe, and drives a plurality of ice cutter claws to hit ice on orbits and railroad crossings or around them. It is characterized by doing.
Here, the backhoe ice rake according to the present invention is connected to the front of the backhoe and is provided with a prime mover main body mounted with a prime mover such as an engine or a motor.

In addition, the ice claw drive mechanism unit includes a drive gear to which the rotation of the prime mover is transmitted, a driven gear installed away from the drive gear, and the plurality of ice claw provided at predetermined intervals. The ice claw holding chain belt spanned between the drive gear and the driven gear so that the drive gear and the driven gear are driven endlessly, and the distance between the drive gear and the driven gear is changed. It is further preferable to have a belt tension adjusting section for adjusting the belt tension.
The bottom surface of the ice claw driving mechanism is provided with an insulator so that the plurality of ice claw driven by the rotation of the prime mover do not contact the rail surface or road surface and do not conduct to the rail. Even better.
The ice cutter main body includes a backhoe side coupling mechanism portion to which an arm tip of the backhoe is coupled, an ice claw driving mechanism support portion that supports the ice claw driving mechanism portion, and the backhoe side coupling mechanism portion. And a turning mechanism part that rotates the whole of the ice claw driving mechanism support part and the whole ice claw driving mechanism part with respect to the backhoe side coupling mechanism part. It is even better if it is configured to include.

  The ice hoist for backhoes according to the present invention is connected to the tip of the arm of the backhoe, and attaches to the rail surface to drive ice hobbing claws and hit the ice on or around the railroad crossing or around the railroad crossings. It is possible to cut not only the ice that is running, but also the ice on and around the rails, on the railroad crossing, and on the surrounding ice.
