Abstract

A mini earth scraper comprised of a bucket which is open at its front end with a scraping edge at the bottom of its open front end, and an open frame having wheels at its back end, wherein the bucket is pivotally attached within the frame. In addition the mini earth scraper has two lifting arms, one of which is attached at one of its ends to one side of the bucket and at its other end to the frame adjacent that side of the bucket; and the other of the lifting arms is attached at one of its ends to the other side of the bucket and at its other end to the frame adjacent that other side of the bucket. In preferred operation the front of the frame is attached to a standard tractor three point hitch. The lifting arms are used to adjust the angle of the bucket relative to the frame, and the three point hitch raises or lowers the frame. When the frame is lowered to just above ground level, and the bucket is inclined at the correct angle by the lifting arms, the scraping edge will engage the ground, and as the frame is pulled forward (by the vehicle to which it is attached) the scraping edge will cut away protrusions not level with the ground's surface, and they will be scooped into the bucket by the forward motion of the bucket. Later the frame can be raised, and the bucket tilted forward to dump out the bucket's load.

Dependent claims

A mini earth scraper comprised of:

a.) a bucket having an open front end, a floor, a back wall, a first side wall called side wall A, a second side wall called side wall B, and a scraping means which is part of the outward facing front bottom edge of the floor;
and
b.) an open frame within which the bucket can be pivotally attached, which open frame has a front end that is attachable to a standard tractor three point hitch, and which open frame has support wheels at its back by means of which it may be rolled when its front end is above the surface along which the frame is to be rolled;
and
c.) wherein the bucket is pivotally attached within the open frame;
and
d.) a first lifting arm called lifting arm A, and a second lifting arm called lifting arm B;
and
e.) wherein when the bucket is pivotally held within the open frame, one end of lifting arm A is attached to the portion of the open frame adjacent side wall A, and the other end of lifting arm A is attached to side wall A, and one end of lifting arm B is attached to the portion of the open frame adjacent side wall B, and the other end of lifting arm B is attached to side wall B.
