Swiveling blade snow blower with central chute

Abstract

This invention is a swiveling blade snow blower with central chute, allowing snow to be blown in the desired direction, whether backing up or going forward. A toothed wheel placed on the side of the swiveling blade is powered by a hydraulic stepping motor that makes the said blade turn forward and backward, plowing the snow through the opening until intercepted by a bidirectional auger that sends the snow at the center of the said auger into the impeller, which propels the snow out, in the desired direction, through the discharge chute located in the centre.

1 . A swiveling blade ( 1 ) snow blower with a central chute ( 23 ) that allows the snow to be blown in the desired direction, whether backing up or going forward. Both ends ( 2 ) of the swiveling blade ( 1 ) are connected to the main frame ( 8 ) with connectors. A toothed wheel ( 4 ) is attached on one side ( 2 ) of the swiveling blade ( 1 ) and connected to a small toothed wheel ( 6 ) by a toothed wheel chain ( 5 ). The small toothed wheel ( 6 ) is attached to the hydraulic stepping motor ( 7 ), which is mounted on the main frame ( 8 ) with connectors and allows the swiveling blade ( 1 ), which is equipped with interchangeable scraping bars ( 3 ) on the front and back, to be oriented, from beneath, to the front or back of the bidirectional auger ( 9 ).  
   
   
       2 . The bidirectional auger ( 9 ), equipped with an impeller ( 10 ) in the center, rotates clockwise, each end being connected to the main frame ( 8 ) with connectors. The bidirectional auger ( 9 ) is equipped with a toothed wheel ( 14 ) attached on one end. A drive chain ( 15 ) connects this toothed wheel with a small toothed wheel ( 16 ), this system being activated by the drive shaft ( 17 ), which is attached to the differential ( 18 ) and the vehicle PTO with the PTO connection ( 19 ).  
   
   
       3 . Removable covers ( 12 ) located on each side, above the bidirectional auger ( 9 ), are attached to the main frame ( 8 ) with hinges, allowing to lift the covers when the snow level is high and let the snow fall on the bidirectional auger ( 9 ), sending it on the impeller ( 10 ). The central cover ( 13 ) allows the impeller ( 10 ) to keep the snow in until it is propelled in the rotor ( 11 ), which is raised to let the swiveling blade ( 1 ) move to the back of the bidirectional auger ( 9 ) under the rotor ( 11 ) case. It is attached to the main frame and can be lifted for maintenance.
