FERTILIZER PLACED Russian patent published in 1994 - IPC

FIELD: agriculture. SUBSTANCE: fertilizer placer has body mounted onto chassis. Chain-bar conveyer and distributing tool 4 provided with drive are mounted onto the body. Drive has cardan and transmission shafts 5 and 6-8 correspondingly which are connected by means of safety clutch 9 and sleeve couplings 10 and 11 with multi-step conic-cylindric reducer 12 which has large transmission gain. Driven shaft of the first step of the reducer is connected with spreading tool 4 by means of shaft 18 and chain gear 19. When fertilizer is equipped with hydraulic drive of the conveyer driven shaft 15 is mounted on bearings in the cup attached to boss of the housing from the right side. Hydraulic motor is attached coaxially from the left. Pinion which has wheels connected with driven shaft of the last reducer step is mounted directly on the shaft of hydraulic motor. Reducer is kinematically connected with driving shafts 29 and 30 of conveyer branches. When fertilizer is equipped with mechanical drive of the conveyer the driven shaft of the first step is mounted onto bearings inside the housing. Pinion is put on the driven shaft or the pinion is made together with the shaft. This pinion is connected with driving shafts 29 and 30 of conveyer branches by means of the same wheels, shafts and chain gear 28. EFFECT: improved efficiency of operation. 2 cl, 6 dwg
