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.

    • SUMMARY OF THE INVENTION
  • The general idea of the invention is to offer a swiveling blade snow blower, allowing snow to be blown in the desired direction, through a central discharge chute, 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 rotate to the rear or front of the bidirectional auger to clear the snow. The bidirectional auger is equipped with an impeller that lifts the snow towards the discharge chute's rotor.
    • BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

    DETAILED DESCRIPTION OF THE INVENTION
  • In the following description, as well as in the related views, the numbers refer to the numbered parts illustrated in the various figures.
  • As illustrated in the FIGS. 1, 2, 3, 4, 5 a, 5 b, is shown a swiveling blade snow blower with central chute designed to be attached to a vehicle (not shown).
  • A double-sided (2) swiveling blade (1), each side being attached to the main frame (8) with connectors. A toothed wheel (4) is installed on one side (2) of the swiveling blade (1) and is connected to a small toothed wheel (6) with a toothed wheel chain (5). The small toothed wheel (6) is connected to the hydraulic stepping motor (7), which is mounted on the main frame (8) with connectors, allowing the swiveling blade (1), which is equipped with interchangeable scraper bars (3) in the front and back, to be oriented to the front or back of the bidirectional auger (9), from beneath.
  • 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).
  • 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.
  • A set of gearwheels (22) operated by a hydraulic motor (20) connects the rotor (11) case to the chute (23), which is activated by a cylinder (21).
  • Although the preferred form of embodiment of the invention is thoroughly described and illustrated hereto, it is understood that the invention is not limited to this particular form of embodiment and that many other modifications could be made without departing from the scope or spirit of the said invention.
  • Other forms of embodiment are possible but they must fall within the range of the following claims
