ICE-BREAKING APPARATUS AND ITS ICE-BREAKING BLADES

摘要

This invention relates to a kind of ice-breaking apparatus and its ice-breaking blades for breaking (layers of ice or snow on roads. The apparatus comprises an ice-breaking roller and ice-breaking blades which are articulated onto the ice-breaking roller. Hinged plates are uniformly fixed on the principal axis of the ice-breaking roller. Hinged holes are uniformly distributed on peripheral circumference of each of the plate. Hinged axis drills through the holes and is articulatly connected with the ice-breaking blades. A torsion spring is used to reduce vibration of the ice-breaking blades. The ice-breaking blades are uniformly and articulatly installed on a supported device which is located on the cylindrical surface, of the ice-breaking roller. Each of ice-breaking blade has bend edge. Another device which may reduce vibration and limit movement of the blades is installed between the blades' tails and the supported device which is articulatly connected with the blade. A shield with an outlet for broken ice is installed on the ice-breaking apparatus. A movement squeegee is installed on the low part of the shield. The roller of the ice-breaking apparatus is not only fit to uneven roads, is convenient for manufacture and low in cost but also fit to clear away, gather and load the broken ice. This invention can reduce the impact between ice-breaking blades and articulated axis, prolong the life of ice-breaking blades.
