CONTROL SYSTEM FOR AGRICULTURAL MACHINE TOOLS, AGRICULTURAL MACHINE FOR WORKING THE SOIL AND/OR SOWING AND METHOD FOR REGULATING THE WORKING DEPTH OF AGRICULTURAL MACHINE TOOLS

摘要

A control system for agricultural working tools (12), such as coulters, cutting discs, rollers or the like, is disclosed, at least two such working tools (12) being pivotably mounted on a carrier (22) each by means of elastic bearing elements (26), which carrier (22) is pivotably mounted or attached to a bearing flange (30) or a frame element (32) of an agricultural machine (10) by means of an actuator (34), the respective angular position of the carrier (22) in relation by means of the actuator (34) is variably changeable on an arable area, whereby the working depth of the working tools (12) can be changed, whereby a measuring means (38) is assigned to measure the working depth at least one working tool (12) and / or the carrier (22). In order to create a control system for regulating the working depth of agricultural work tools, in which the number of actuators is reduced to a minimum and a hydraulic or fluid coupling between the work tools can be dispensed with, but also enables the respective work tools to evade when hitting obstacles , it is provided that the actuator (34) is controlled on the basis of the working depth determined by means of the measuring means (38) and the number of working tools (12) mounted on the common carrier (22). In addition, a method for regulating the working depth of agricultural Working tools (12) disclosed.
