Apparatus for cleaning turfed ground

A cleaning apparatus comprising:

• a chassis;
• a roller mounted on the chassis for rolling on turf and having an axis of rotation of the roller;
• a cylindrical brush mounted on the chassis, parallel to the roller, and rotating in a direction opposite rotation of the roller, about an axis of rotation of the cylindrical brush, for picking up waste from the turf;
• a collecting pan integral with the chassis, wherein
• the cylindrical brush is located between the roller and the collecting pan,
• the collecting pan includes an opening having a lower edge and the cylindrical brush, in rotating, projects the waste picked up from the turf into the collecting pan through the opening, and
• the cylindrical brush is in contact with the roller to clean waste picked up from the turf and deposited on the roller;
• and
• a bowed plate structure mounted on the chassis between the cylindrical brush and the collecting pan, wherein the bowed plate structure includes
• a bowed plate opposite, facing, and having a curvature concentric with the cylindrical brush, located between the cylindrical brush and the collecting pan, and extending longitudinally along substantially all of the cylindrical brush, wherein
• the bowed plate is swept by the cylindrical brush when the cylindrical brush rotates, and
• the bowed plate structure is pivotally mounted on the chassis and freely pivots in relation to the chassis, around the axis of rotation of the cylindrical brush,
• an upper wall contiguous, at a first bend, with an upper part of the bowed plate, located between the upper part of the bowed plate and the lower edge of the opening of the collecting pan, and directly beneath the lower edge of the opening in the collecting pan, and inclined toward the bowed plate with respect to the cylindrical brush so that the waste projected by the cylindrical brush toward the collecting pan and not entering the opening in the collecting pan falls toward and onto the upper wall and is directed down the bowed plate so that the waste not collected in the collecting pan may be picked up and projected a second time by the cylindrical brush toward the opening in the collecting pan,
• a lower wall contiguous, at a second corner, with a lower part of the bowed plate, inclined away from the bowed plate, and extending away from the lower part of the bowed plate with respect to the cylindrical brush, and
• an upwardly curved end wall contiguous, at a rounded corner, to and extending from the lower wall, opposite and facing part of the bowed plate, wherein the rounded corner rests on the turf when the turf is being cleaned and confines the waste that has been directed down the bowed plate so that the waste may be picked up a second time by the cylindrical brush.
