Abstract

A remnant snow removing apparatus for a snow thrower includes a scraper bucket and at least one extension panel located on the scraper bucket. The scraper bucket includes a central plate and two side plates at two sides of the central plate. The extension panel is extended from one side plate to clear remnant snow scattered during snow clearing. The scraper bucket and extension panel further have respectively a first coupling portion and a second coupling portion that include respectively a plurality of first positioning surfaces and second positioning surfaces that are latched with each other for positioning. The first positioning surfaces and second positioning surfaces are formed annularly on the first and second coupling portions in equiangular and polygonal structures. Users can assemble and disassemble the extension panel and adjust the included angle between the extension panel and scraper bucket according to their requirements.

Claims

1. A remnant snow removing apparatus for a snow thrower, comprising:

a scraper bucket including a central plate, two side plates at two sides of the central plate to jointly form a housing compartment there between to hold accumulated snow, and a first coupling portion, the two side plates being spaced from each other to define a snow clearing swath; and

at least one extension panel which includes a second coupling portion detachably coupled with the first coupling portion, the extension panel being extended from one side plate to form an included angle with the side plate to form a remnant snow clearing space outside the snow clearing swath;

wherein the first coupling portion includes a plurality of first positioning surfaces and the second coupling portion includes a plurality of second positioning surfaces latched with the first positioning surfaces to form positioning relationship, the first and second positioning surfaces being formed annularly on the first and second coupling portions in equiangular and polygonal structures.

2. The remnant snow removing apparatus of claim 1, wherein the first coupling portion and the second coupling portion are respectively a strut and a recess.

3. The remnant snow removing apparatus of claim 1, wherein the first coupling portion and the second coupling portion are respectively a recess and a strut.

4. The remnant snow removing apparatus of claim 1, wherein the scraper bucket is coupled with a fastening plate, the first coupling portion being fastened to the fastening plate, the fastening plate and the scraper bucket including respectively a fastening hole corresponding to each other to receive a first fastening element for securing.

5. The remnant snow removing apparatus of claim 1, wherein the scraper bucket is sandwiched by two clamping plates to clamp the scraper bucket, the first coupling portion being fastened to the two clamping plates.

6. The remnant snow removing apparatus of claim 5, wherein at least one clamping plate including a fastening hole run through by a second fastening element to butt the scraper bucket.

7. The remnant snow removing apparatus of claim 1, wherein the extension panel includes a buffer member butting the ground surface.

8. The remnant snow removing apparatus of claim 7, wherein the buffer member is a rubber stripe.
