| 摘要 |
The invention concerns a precision disc tiller comprising a frame (1) equipped with at least a front gang (2) of non-motorised rotary tilling discs, said discs (2), being mounted independent and oscillating relative to the frame, operating on the soil at a topsoiling level adjustable via at least a reference member (3) coupled to said frame, sowing elements (4) and a device for burying seeds. Said disc tiller is characterised in that the sowing elements (4) are arranged downstream of the front gang (5) of tilling discs (2) such that the seeds are deposited on a bed of soil formed by the front gang (5) of tilling discs (2) and the burying device consists of a rear gang (6) of non-motorised rotary tilling discs (2), said discs operating in the soil at a topsoiling level adjustable via said reference member (3), each tilling disc (2) of the rear gang (6) of tilling discs (2) being mounted independent and oscillating relative to the disc tiller support frame (1). |
