MOBILE GRAIN AND FERTILISER DRILL Russian patent published in 2014 - IPC A01C7/06 

FIELD: agriculture.

SUBSTANCE: grain and fertiliser wide-cut mobile drill comprises a frame, rear non-removable and front quick-removable wheels, the front bearing frame mounted on the middle of the drill frame. The frame is connected in front using a vertical support hinge with the cross-beam for installation of the front quick-removable wheels, and the working draft beam with the telescopic jib. The bearing frame is connected from behind to the drill frame by means of the vertical support hinge and in the operating position it is fixed perpendicular to the drill frame by means of foldable or flexible guyropes with the stretching screws. The guyropes are connected with one end in front with the bearing frame, the other - on the edges with the drill frame. In the transport position the bearing frame with the draft beam, turning on the vertical support hinge, is installed and fixed along the drill frame. Also on the frame the lower and the upper yokes are mounted for connecting with the rods of the rear hinged system of the tractor. The lower frame beam is reinforced. The building-block approach of the drill with the tractor is carried out regardless of the presence of the working draft beam on the drill work with the bearing frame.

EFFECT: invention provides operation of the drill in the trailed, semi-hinged and hinged versions with the proportional allocation of the tractive force in width of the drill with the simultaneous reduction of metal consumption.
