Abstract
A cultivator wheel is disclosed for use in agricultural machines. It has a hub and tines which project substantially radially from the hub and are provided with pointed outer end portions. These tines are bent out of the central radial plane of the wheel. Portions of the wheel are formed with cutting edges that are inclined circumferentially of the wheel as well as relative to the central radial plane of the same.
Claims12
A cultivator wheel having an axis and adapted for rotation about said axis, comprising a hub;
- a plurality of successive triangular tines having pointed end portions and being distributed about said hub, successive ones of said tines being bent in opposite directions out of a central radial plane of said wheel, said tines having shorter sides and longer sides, said shorter sides of said tines extending nonradially relatve to said axis, said longer sides of said tines being provided with cutting edges each extending substantially along the full length of the respective one of said longer sides and inclined to said central radial plane;
- said wheel being provided with openings between said cutting edges and said hub.
A cultivator wheel for agricultural machines, comprising a hub;
- a plurality of tines projecting radially of said hub and having pointed end portions, said tines being bent out of central radial plane of said wheel and provided with cutting edges inclined substantially radially;
- said hub having a center opening and being provided with cut-outs forming radial bays extending outwardly from said center opening.
A cultivator wheel having an axis and rotatable in a predetermined direction about said axis, said wheel comprising a hub;
- a plurality of successive triangular tines having pointed end portions and being distributed about said hub, successive ones of said tines being bent in opposite directions out of a central radial plane of said wheel, said tines having shorter sides and longer sides, said short sides of said tines extending nonradially relative to said axis, said longer sides of said tines being provided with cutting edges each extending substantially along the full length of the respective one of said longer sides and inclined to said central radial plane, each of said longer sides of said tines leading the respective shorter side thereof relative to said predetermined direction;
- said wheel being provided with openings between said cutting edges and said hub.
A cultivator wheel comprising a hub having a center opening and cut-outs extending radially outwardly of said center opening for the passage of soil particles therethrough;
- a plurality of successive triangular tines having pointed end portions and being distributed about said hub, successive ones of said tines being bent in opposite directions out of a central radial plane of said wheel, said tines having shorter sides and longer sides, said longer sides of said tines being provided with cutting edges inclined to said central radial plane;
- said wheel being provided with openings between said cutting edges and said hub;
- and a mounting flange mounted on said hub overlying said center opening and having a shaft-receiving aperture of polygonal cross section.
