Abstract

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.

First claim

What is claimed is:

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 (LT 1 ) of two longitudinal sides (LT 1 , LT 2 ) 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 (LA 1 ) of two longitudinal sides (LA 1 , LA 2 ) 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 (LA 1 ) of the working device is supported on the first longitudinal side (LT 1 ) of the trailer and wherein the second longitudinal side (LA 2 ) of the working device faces the same direction as the second longitudinal side (LT 2 ) 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.

2. The position-securing mechanism according to claim 1 , wherein the first functional section of the receiving device comprises a first support brace that extends horizontally lengthwise and in the longitudinal direction (LR) of the trailer and wherein the second functional section of the receiving device has a recess that is open vertically downward and configured such that, by reaching over and straddling the first support brace, the support brace is engageable in the recess thereby forming the support bearing (SL), and therefore the first longitudinal side (LA 1 ) of the working device is supported against the first longitudinal side (LT 1 ) of the trailer.

3. The position-securing mechanism according to claim 1 , wherein the first functional section of the receiving device comprises a second support brace that extends horizontally lengthwise and in the longitudinal direction (LR) of the trailer, wherein the second functional section of the receiving device has an end section that is disposed such that the end section bears against an outer circumference of the second support brace when the support bearing (SL) is formed and wherein the second support brace and the end section are offset outwardly relative to the support bearing (SL) by a predetermined extent transversely to the longitudinal direction (LR) of the trailer and vertically downward by a predetermined extent.

4. The position-securing mechanism according to claim 1 , wherein the second functional section of the receiving device has a first sliding surface that faces vertically downward and extends horizontally lengthwise and transversely to the longitudinal direction (LR) of the working device and is offset by a predetermined extent outwardly relative to the support bearing (SL) transversely to the longitudinal direction (LR) of the working device.

5. The position-securing mechanism according to claim 4 , wherein the second functional section of the receiving device has a second sliding surface that extends directly adjacent to an inner longitudinal end of the first sliding surface that extends transversely to the longitudinal direction (LR) of the working device, and therefore the second sliding surface provides a sliding connection between the first sliding surface and the support bearing (SL), and wherein the first sliding surface is offset vertically downward by a predetermined extent relative to the support bearing (SL).

6. The position-securing mechanism according to claim 4 , wherein the first functional section comprises a notched strip that extends horizontally lengthwise and in the longitudinal direction (LR) of the trailer and has, on a vertically upper longitudinal edge thereof, a plurality of recesses that are equidistantly spaced apart from one another in the longitudinal direction (LR) and wherein the notched strip is disposed such that upon mutual engagement of the first and the second functional section, the first sliding surface is engaged in one of the recesses and rests on a base section thereof.

7. The position-securing mechanism according to claim 6 , wherein the notched strip is vertically displaceable and is spring-loaded vertically upward.

8. The position-securing mechanism according to claim 4 , wherein the first functional section comprises a first and a second notched strip, each of which extends horizontally lengthwise and in the longitudinal direction (LR) of the trailer and each of which has, on a vertically upper longitudinal edge thereof, a plurality of recesses that have a predetermined longitudinal extension and are equidistantly spaced apart, wherein the recesses of the first notched strip are offset in the longitudinal direction (LR), relative to the recesses of the second notched strip, by approximately half of the longitudinal extension and wherein the first and the second notched strip are each vertically displaceable and are spring-loaded vertically upward and are disposed such that, upon mutual engagement of the first and the second functional section, the first sliding surface is engaged in one of the recesses of one of these two notched strips and rests on a base section of the particular recess.

9. A device unit, comprising:
an agricultural working device that is attachable to an agricultural working machine via a coupling device and has a first and a second longitudinal side (LA 1 , LA 2 ) that face away from each other and extend along a longitudinal direction (LR) of the working device;
a trailer for the working device having a first and a second longitudinal side (LT 1 , LT 2 ) that face away from one another and extend along a longitudinal direction (LR) of this trailer; and
a position-securing arrangement provided on the respective first longitudinal sides (LA 1 , LT 1 ) of the working device and the trailer that comprises two position-securing mechanisms as set forth in claim 1 ,
wherein a first position-securing mechanism of the two position-securing mechanisms is disposed in the longitudinal direction (LR) of the trailer, adjacent to a front wheel axle thereof and a second position-securing mechanism of the two position-securing mechanisms is disposed in the longitudinal direction (LR) of the trailer adjacent to a rear wheel axle thereof.

10. The device unit according to claim 9 , wherein, in each of the two position-securing mechanisms, the second functional section of the receiving device has a hook-shaped indentation that is open toward the second longitudinal side (LA 2 ) of the working device and is engageable with a section of the first functional section that is used to form the support bearing (SL), by horizontally displacing the first longitudinal side (LA 1
