Abstract
The device consists of two longitudinally extending side frame members connected at one end to a diking plate and at the other end to a transverse frame member which in turn is connected to a hitch which allows the frame and diking plate pivotal movement in both a vertical and a horizontal plane. Connected medially of each side frame member is a pillow block bearing which bearings support, on a single axis, a pair of spoked wheels. Each of the spoked wheels has one spoke of greater length than the remaining spokes which longer spokes extend outward in a common radial plane. As the spoked wheels turn, the diking plate is lifted periodically from the ground to provide a damming action in a furrow in the earth.
Claims4
In combination, a dike forming device and a lister point comprising:
- a longitudinally extending frame;
- a plate member connected at one end of said frame;
- a hitch means connected to the opposite end of said frame for attaching said frame to said lister point, said hitch means including a pair of vertically oriented plates disposed adjacent opposite sides of said lister point and further including a horizontal pivot axis and a vertical pivot axis;
- wheel means connected to said frame for supporting said frame, said wheel means including a plurality of radially extending spokes with at least one of said spokes being longer than one other of said spokes;
- a cylindrical band connected on one side to each of said spokes for supporting said wheel means in soft soil, each of said spokes having a free end extending radially outward of said band;
- a reinforcing member connected between the outer surface of said cylindrical band and the free end of said at least one longer spoke;
- and bearing means supporting and journalling said wheel means on said frame.
