Abstract
A ditch forming implement includes a frame supported for movement across the ground in a forward working direction when connected to a towing vehicle. A rotating member, for example a tire having a resilient main body and integral resilient paddles formed thereon, is rotatably supported on the frame within an upright plane oriented transversely to the forward working direction. The frame may also support a shovel on an implement shank spaced forwardly of the rotating member, an adjustable guide wheel supported rearwardly of the rotating member for controlling depth of the rotating member, and a grader blade supported forwardly and laterally offset to one side of the rotating member for widening a ditch to be formed by the implement.
Claims20
A ditch forming implement comprising:
- a frame arranged to be supported for movement across the ground in a forward working direction;
- a rotating member supported on the frame for rotation about a respective axis of rotation such that the rotating member rotates within an upright plane of rotation perpendicular to the axis of rotation and transverse to the forward working direction, the rotating member comprising a rim rotatably supported on the frame and a pneumatic tractor tire supported on the rim, the pneumatic tractor tire comprising:
- a main body which is substantially circular about the axis of rotation;
- and
- a plurality of paddles supported on the main body at spaced apart positions in a circumferential direction about the axis of rotation;
- each paddle having a working surface which extends radially outward from the main body transversely to the circumferential direction;
- and
- the main body and each paddle being formed integrally and seamlessly with one another of a resilient material.
A ditch forming implement comprising:
- a frame including a tool bar arranged for connecting to a towing vehicle so as to be supported for movement across the ground in a forward working direction, a first trailing arm coupled on the tool bar to extend rearwardly therefrom and a second trailing arm coupled on the tool bar to extend rearwardly therefrom separately from the first trailing arm;
- a rotating member supported on the first trailing arm of the frame for rotation about a respective axis of rotation such that the rotating member rotates within an upright plane of rotation perpendicular to the axis of rotation and transverse to the forward working direction, the rotating member comprising:
- a main body which is substantially circular about the axis of rotation;
- and
- a plurality of paddles supported on the main body at spaced apart positions in a circumferential direction about the axis of rotation;
- each paddle having a working surface which extends radially outward from the main body transversely to the circumferential direction;
- and
- each paddle being formed of a resilient material;
- and
- a grader blade supported on the frame forwardly and laterally offset to one side of the rotating member, the grader blade having a first portion at an inner end of the grader blade which is supported on the first trailing arm and a second portion which supported on the second trailing arm such that a lower working edge of the grader blade is inclined inwardly and rearwardly towards the rotating member;
- the second trailing arm being pivotal relative to the toolbar and the first trailing arm such that an elevation of the second portion of the grader blade is adjustable relative to the first portion of the grader blade.
