Forage harvester for attachment or attachment to a tractor

The invention relates to a forage harvester for attachment or attachment in front of, behind or to the side of a tractor with a gear that can be swiveled into different swivel positions around the drive axis of the chopper, which is a A drive gear that can be firmly attached to the drive axle and has a drive gear meshing with the output gear and carrying a stub shaft, and in which the transmission a device for fastening in at least one pivot position aufwei st.

With a known forage harvester (Pöttinger forage harvester MEX-IV) it is possible to place it in front of or behind the tractor to grow. Since the direction of rotation of the PTO shaft of the tractor is standardized, it is necessary that the PTO shaft rotation direction will be changed. This is done by means of a reverse gear, which in the known forage harvester on the

Knife wheel shaft is attached and through, a locking cam can be fixed by 360 ° in steps of 30 °! can. Is the correct for the selected work position The direction of rotation of the tractor PTO coincides with the direction of rotation of the knife wheel shaft, but shows the position The difference between the two shafts was too great, which resulted in extreme angular deflection of the cardan shaft the installation of a shift gear is required. This shift gear can also be made in steps of Can be swiveled by 360 ° by 30 °.

In disc chopper with large chopping wheel diameters, as they are increasingly used in multi-row harvesting machines Find it is important to reverse the grinding process with carry out rotating knife wheels to the working direction of rotation. This prevents the knife edges get stuck on the grinding wheels, which can lead to the destruction of the knife edge. If you want to sharpen the knife edges of the well-known "forage harvester, extensive modifications or additions are necessary because of the reversal of the direction of rotation.

The invention is based on the object of a forage harvester of the type mentioned so that it always rotates in the correct direction regardless of its position on the chopper can be operated.

This object is achieved according to the invention in that a second, meshing with the existing drive gear and. a drive gear carrying a shaft stub is provided.

With this design according to the invention, it is possible to connect a forage harvester to any PTO shaft of the tractor without additional large changes or. Replacement work in

to operate in the correct direction of rotation. In addition, this training has the further advantage that the
Grinding the knife of the disc wheel is made much easier. It is only necessary to pull the cardan shaft off the shaft stub of the work drive gear currently in use and to place it on that of the other drive gear.

A particularly flat design is achieved in that all the gears are arranged in one plane.

The invention is explained in more detail below with reference to the drawings. Show it:

Pig. 1 is a side view of a forage harvester attached to a tractor,

FIG. 2 shows a view of a schematic representation of the transmission on the forage harvester, and FIG

3 shows a side view of the transmission with a disk wheel and disc wheel housing.

On the towing vehicle 1 shown in Fig. 1, which can be any motorized land vehicle, a forage harvester 2 is attached in the front working position. In the drawing the working direction is indicated by an F. If there is also a rear PTO, the forage harvester 2 ' can also be attached to the rear ", whereby the working direction is entered with F '.

The forage harvester is equipped with an upper link connection 4 and a lower link connection 5 is attached to the tractor 1.

The cardan shaft 6 transmits the torque ν cn of the PTO shaft of the tractor to the transmission 3. The transmission 3 is arranged on the wall of the chopper housing facing the tractor.

In Mg, 2 is the gearbox on the chopper housing in a front view shown. The output gear 9 is on the Häckselradwelle 7 aligned with the Häckselradachse 8 firmly attached. With the output gear 9 the drive gear 10 is in mesh. The output gear 9 and the drive gear 10 have the same number of teeth. ItLt the drive gear 10 is located Another drive gear 11 engages. The drive gear 11 is arranged laterally next to the drive gear 10. The two drive gears and 11 each have a stub shaft 12 and 13 for engagement with the cardan shaft 6. The distance between the axes of the drive gears 10 and 11 can be the same as the distance between the chopper wheel axis 8 and the axis of the drive gear wheel 10. The gears are in the Gear housing 14- mounted and enclosed by it.

The drive gear 11 is as close as possible to that Output gear 9 moved closer to the angle between the drive shaft stubs 12, 13 and the propeller shaft to keep similar in order to avoid that each time the cardan shaft 6 is repositioned - during the grinding process - a Change in the position of the gear 3 must be made.

The side view shown in Figure 3 shows clearly the arrangement of the face-toothed gears of the transmission in one plane. After pivoting around the chopping wheel axis 8 of the chopping wheel 17, the transmission can be attached to the fastening device designed as a locking device be fixed in the desired angular position.
