DEVICE FOR MOUNTING SCRAPER ASSEMBLY ON AUXILIARY BEARING OF DISC RIPPER, WHICH ALLOWS DEVIATION OF SCRAPER ASSEMBLY Russian patent published in 2015 - IPC A01C7/20 A01B49/06 

FIELD: agriculture.

SUBSTANCE: assembly for loosening the soil for agricultural drill machine comprises a bracket, a disc, a scraper assembly, a holder of the scraper, a seeding tube and a pin. The bracket is attached to the frame of the device. The disc is mounted with the ability to rotate on the bracket for forming furrow in the soil. The scraper assembly comprises a scraper. The scraper has an edge for contacting and cleaning the disc surface and a mounting area remote from the edge. The scraper by means of the holder is secured adjacent to the disc. The seeding tube is located adjacent to the disc surface for throwing seeds into the furrow formed by the disc. The seeding tube is connected with the holder of the scraper. The pin connects freely the scraper holder with the bracket. The pin forms a substantially fixed rotational axis, around which the scraper and the seeding tube can be rotated in response to deviation of the disc. The agricultural device has a tool bar and a plurality of assemblies for loosening the soil. The bar is made with the ability to connect to the towing vehicle. The assemblies for loosening the soil are connected to the tool bar. Each assembly for loosening the soil comprises an auxiliary bearing, a disc, a seeding tube unit and a scraper. The bearing is made with the ability to connect to the tool bar. The disc is rotatably mounted on the auxiliary bearing for forming furrow in the soil. The seeding tube unit is pivotally mounted on the auxiliary bearing and comprises the seeding tube for throwing seeds into the furrow formed by the disc. The scraper is mounted on the seeding tube unit and has an edge for scraping the surface of the disc. The scraper is made with the ability to rotate with the seeding tube unit. The seeding tube unit is rotatable along the fixed axis of rotation formed by mounting the seeding tube unit on the auxiliary bearing.

EFFECT: constructive implementation of the device and assembly for loosening the soil and planting enables to ensure high-quality cleaning of the disc through reliable contact of the scraper edge with the disc surface at its deviations in the process of operation.
