EROSION CONTROL ROLLER-DIBBLER Russian patent published in 2005 - IPC

FIELD: agricultural engineering; erosion control.

SUBSTANCE: proposed roller-dibbler contains two spirals, one placed inside the other. Inner spiral coil pitch is variable over length. Diameter of inner spiral relates to diameter of outer spiral as 2:3. Trapezoidal elastic cleaners are installed on roller frame between coils of outer spiral. Blades for one-time interaction of one blade with cleaner at one turn are rigidly secured on outer spiral. Ballast box with cover is installed on roller frame. Blades are fitted on outer spiral at different angles to axis of coils.

EFFECT: improved quality of soil erosion control by decreasing action of roller onto soil and excessive breaking of soil.
