Title: SOWING COULTER ARRANGEMENT OF AN AGRICULTURAL MACHINE
Abstract:
A sowing coulter arrangement (10) of an agricultural machine for soil cultivation and/or for dispensing material to be spread, such as seed, fertilizer or the like is disclosed, which comprises at least one suspension apparatus (16) for mounting the sowing coulter arrangement (10) on a frame construction, a coulter frame (20), connected to the suspension apparatus (16), for mounting the components of the sowing coulter arrangement (10) thereon, and a coulter disc (22) arranged in a rotatable manner on the coulter frame (20) and/or a tine implement for creating a seed furrow. Furthermore, the arrangement comprises a pressing roller (48) that is mounted on the coulter frame (20) in a rotatable manner and/or by means of tandem and is mounted in a rotatable manner via a pivot point (50), or furrow closing implements for closing the seed furrow, a metering apparatus (32) for the at least largely separate dispensing of material to be distributed, a seed tube (26) for transporting the material to be distributed from a metering apparatus (32) to a seed furrow, and a catching element (42), arranged downstream of the outlet (30) of the seed tube (26), for catching the material to be distributed. In order to ensure durable and uniform dispensing of material to be dispensed from a seed tube into a seed furrow, provision is made for the metering apparatus (32), the seed tube (26) and the catching element (42) to form a unit and to be mounted on a carrier (62) that is attached in a pivotable manner to the coulter frame (20) or to a frame construction, with the result that an arrangement of an outlet (30) of a seed tube (26) with respect to a catching element (42) is always kept largely constant.
