Position-securing mechanism and device unit equipped therewith

摘要

A position-securing mechanism and a device unit equipped therewith for securing a working device to a trailer is designed to the working device is attachable to a working machine via a coupling device. The position-securing mechanism is formed with a sensor designed to detect a coupled state and a decoupled state of the coupling device, a receiving device having first and second functional sections provided on a first longitudinal side of the trailer or the working device, a locking device that is brought into a locked state in which this locking device prevents the release of the engagement of the functional sections and into an unlocked state in which this locking device permits the release of this engagement and a drive device connected to the sensor and driven thereby.

1. A position-securing mechanism for securing a position of an agricultural working device on a trailer, where the working device attachable to an agricultural working machine via a coupling device, the position-securing mechanism comprising:
a sensor provided on the coupling device, on the working device side, designed to detect a coupled state and a decoupled state of the coupling device; a receiving device having a first functional section, which is provided on a first longitudinal side (LT1) of two longitudinal sides (LT1, LT2) of the trailer, which face away from one another and extend along a longitudinal direction (LR) of this trailer, and a second functional section, which is provided on a first longitudinal side (LA1) of two longitudinal sides (LA1, LA2) of the working device, which face away from one another and extend along a longitudinal direction (LR) of this working device; wherein the first and the second functional sections are engaged with one another to forming a support bearing (SL), and therefore the first longitudinal side (LA1) of the working device is supported on the first longitudinal side (LT1) of the trailer and wherein the second longitudinal side (LA2) of the working device faces the same direction as the second longitudinal side (LT2) of the trailer; a locking device disposed on the working device and selectively brought into a locked state in which this locking device prevents the release of the engagement of the two functional sections of the receiving device and into an unlocked state in which this locking device permits the release of the engagement of the two functional sections of the receiving device; and a drive device disposed on the working device and is connected to the sensor in order to be controlled thereby, and is connected to the locking device in order to drive this locking device, wherein the locking device is brought into the locked state when the sensor detects the decoupled state and is brought into the unlocked state when the sensor detects the coupled state.
