Abstract

PURPOSE: To prevent the edge of a plow from being broken by rotatably pivoting a cutting edge on a reinforcing member under the snowplow body and fixing the rotary movement of the edge by a shear pin and cutting the shear pin when an obstacle acts on the edge. CONSTITUTION: A plow 1 equipped on a snowplow is constituted of a plow body 2 and a cutting edge 3. A reinforcing member 5 is provided at the rear face of the plow body 2 and a rotary body 6 is pivoted at the rear part of the reinforcing member 5. The cutting edge 3 is fixed to the rotary body 6 and the plow body 2 and the cutting edge 3 are made to be nearly flush with each other to constitute the plow 1 front face. Further, through holes 12, 15 are formed in the reinforcing member 5 and the rotary body 6. A shear pin 16 is inserted in both holes to temporarily fix the rotary body 6. Accordingly, when a shock acts on the edge, the shear pin 16 is broken and the edge is rotated rearward. In this way, the edge is prevented from being broken.
