Curved blade adapted for a snow blower provided with and interchangeable cutting edge and of a sliding protective plate fixed under the curved blade replaceing the ground shoe

Abstract

A curved blade mounted to bottom from both curved sides joining the blade rotation mechanism components assembling allows the height adjustment according to the desired rotational movement, and is assembled to the parts for transmitting motion fixed onto the snow blower. A sliding protective plate replacing the ground shoe, is mounted under the curved blade provided with an interchangeable cutting edge protecting the curved blade and the gravel inputs or all other materials during the snow blowing. The curved blade and the blade rotation mechanism components assembling are configured for allow to be assembled to the parts for transmitting motion fixed onto the snow blower adapted for a wheel tractor.

The embodiments of the invention for which an exclusive property or privilege is claimed, are defined as follows:  
     
         1 . Means for releasably mounted a curved blade on a snow blower, said means comprising: 
 a curved blade mounted to bottom from curved both sides of said blade,    the blade rotation mechanism components assembling is mounted to the parts for transmitting motion fixed to the snow blower by the blade rotation mechanism, and levers activate the arms cylinder joined to the curved blade mounted to said bottom from curved both sides of said blade,    said blade rotation mechanism components assembling is activated by two hydraulic cylinders fixed to the snow blower by the end stop,    a sliding protective plate replacing the ground shoe is mounted under said curved blade provided with an interchangeable cutting edge protecting said curved blade and the gravel inputs or all other materials during the snow blowing.    
     
     
         2 . The means according to  claim 1 , in which said curved blade mounted to said bottom from curved both sides is made of suitable material which exibits excellent hardness, resistance and toughness properties, comprises three principal components, which a short cylindrical part including an internal squared shape passes through a short cylindrical part provided with cup grease for the lubricating of said part. The elongated squared pressure part passes through said blade rotation mechanism making turn said short cylindrical part inwardly from said short cylindrical part.
