Soil spreading scraper device

A soil spreading scraper device comprising:

• a frame supported for movement along the ground in a forward working direction;
• an impeller member supported on the frame for rotation about an impeller axis within a plane of rotation lying generally perpendicularly to the impeller axis, the plane of rotation extending generally upward and rearward at an angle between 45 degrees and 75 degrees from horizontal;
• a cutting blade supported on the frame forwardly and downwardly relative the impeller member and arranged to cut a top layer of soil from the ground as the frame is displaced in the forward working direction;
• a kicker supported on the frame for rotation about a kicker axis spanning above the cutting blade transversely to the forward working direction and arranged to propel soil cut by the cutting blade generally rearward onto the impeller member;
• the impeller member comprising a disc body and a plurality of impeller blades supported on the disc body so as to be arranged to spread soil deposited on the impeller member generally radially outward from the impeller axis as the impeller member is rotated;
• each of the impeller blades comprising:
• a main body portion which projects generally upward from the disc body in a direction of the impeller axis and which extends radially outward from an inner end in proximity to the impeller axis to an outer end in proximity to a peripheral edge of the impeller member;
• and
• a wear member supported on the main body portion to project radially outward beyond the outer end of the main body portion;
• the wear member being adjustable in a radial direction relative to the main body portion of the impeller blade.

A soil spreading scraper device comprising:

• a main frame supported for movement along the ground in a forward working direction;
• an impeller member supported on the main frame for rotation about an impeller axis within a plane of rotation lying generally perpendicularly to the impeller axis, the plane of rotation extending generally upward and rearward at an angle between 45 degrees and 75 degrees from horizontal;
• a cutting blade supported on the main frame forwardly and downwardly relative the impeller member and arranged to cut a top layer of soil from the ground as the main frame is displaced in the forward working direction;
• a kicker supported on the main frame for rotation about a kicker axis spanning above the cutting blade transversely to the forward working direction in a working direction so as to be arranged to propel soil cut by the cutting blade generally rearward onto the impeller member;
• the impeller member comprising a plurality of impeller blades arranged to spread soil deposited on the impeller member generally radially outward from the impeller axis as the impeller member is rotated;
• a reverser assembly comprising:
• a unitary reverser frame mounted on the main frame so as to be readily releasable from the main frame;
• a ratchet wheel mounted about the kicker axis, the ratchet wheel including a plurality of circumferentially spaced apart ratchet teeth thereon;
• a ratchet pin supported on the unitary reverser frame so as to be arranged for ratcheting engagement with the ratchet teeth on the ratchet wheel;
• a linear hydraulic actuator supported on the unitary reverser frame and supporting the ratchet pin thereon so as to be arranged to stroke the ratchet pin in a first direction towards a first position and in an opposing second direction towards an opposing second position;
• a guide supported on the unitary reverser frame so as to be arranged to restrict movement of the ratchet pin substantially along one side of the ratchet wheel between the first and second positions;
• the ratchet pin and the ratchet teeth on the ratchet wheel being configured such that the ratchet pin is slidably displaced over the ratchet teeth without rotating the ratchet wheel when displaced in the first direction and such that the ratchet pin positively engages one of the ratchet teeth to drive rotation of the ratchet wheel when displaced in the second direction;
• the ratchet wheel being coupled to the kicker such that the kicker is rotatable with the ratchet wheel about the kicker axis in a direction opposite to the working direction when the ratchet wheel is rotated with displacement of the ratchet pin in the second direction;
• wherein the linear hydraulic actuator, the ratchet pin, and the guide are adapted to remain supported on the unitary reverser frame as a unitary assembly when the reverser frame is removed from the main frame.
