专利说明:

The invention relates to a round baler for stalk crop with a mounted on a chassis press housing, which includes a chassis fixed housing part and a swivel mounted on this housing part about an upper pivot axis ejector flap which limits an ejection opening for the rolling out of the press housing Halmgutballen in an open position.
For the production of round bales from agricultural stalk material round balers are used, which have arranged on a chassis pressing housing with a pressing chamber, the jacket of drivable, mounted in the press housing press rolls is formed (EP 1 602 270 A1). The stalk material picked up by a receiving conveyor when passing over from the ground is optionally conveyed into the press chamber after comminution between two press rolls and circulated through the driven press rolls and wound into a bale which is formed by the continuous feed of the straw material forming on the outside of the already formed reel is increasingly compressed.
The stalk bale thus formed is then wrapped within the crimping chamber with a foil or net before it is ejected. For this purpose, the press housing is divided into a housing part fixed to the chassis and a discharge flap mounted pivotably about this on an upper pivot axis. When opening the ejection flap thus rolls the sheathed straw bales supported by the driven press rollers in the bottom region of the chassis-fixed housing part through the released from the discharge flap ejection opening from the press housing on the floor. Since this ejection from the press housing is unrestrained, there is a risk, especially in sloping soils, that the ejected straw bale unrolled rolls away from the round baler.
The invention is therefore based on the object, a round baler for stalk material in such a way that the ejected from the compression housing Halmgutballen can be stored controlled using simple design measures on the floor.
Starting from a round baler of the type described above, the invention solves the task by the fact that the ejector flap at its opposite end of the pivot axis has a catching position in the runway of rolling from the press housing Halmgutballens catch stop for the Halmgutballen.
By the pivoting of the discharge flap in a tuck position in the runway of rolling from the press housing on the floor projecting Halmgutballens the Halmgutballen is braked and therefore comes braked to rest on the ground, so that even with a sloping ground, the danger of a Weitererrollens the Halmgutballens banned can be. To release the Halmgutballens the catch stop of stalk bales is to lift off, which can be achieved in a simple manner by pivoting the ejector flap from the catch position to the open position. But it would also be possible to shift the catch stop against the discharge flap for this purpose.
Since the mass of Halmgutballen is comparatively large, it is recommended a damped braking of ejected from the compression housing Halmgutballen.
For this purpose, the catch stop can be supported via a damping spring against the discharge flap.
To be able to largely exclude a risk of damage to the shell of the jacketed straw bals by frictional forces between the shell and the catch stop, the catch stop can be designed as a freely rotatably mounted catch roller so that the catch roller can roll on the shell of Halmgutballens without adversely affecting the braking effect , Particularly simple construction conditions arise in this context, when the catch stop is held in acted upon by the damping spring, lateral pivot levers, because in this case not only simple design conditions can be met, but also a particularly gentle deceleration of Halmgutballen is achieved.
In the drawing, the subject invention is shown, for example. Show it
Fig. 1 shows a round baler according to the invention in a partly torn schematic side view with closed discharge flap and Fig. 2 this round baler in a representation corresponding to FIG. 1, but with the ejection flap pivoted into the catching position.
The round baler according to the illustrated embodiment has a arranged on a chassis 1 press housing 2, which is divided into a chassis-fixed housing part 3 and an ejector flap 4, which is mounted pivotably about an upper pivot axis 5 on the chassis-fixed housing part 3. The press housing 2 comprises a press chamber, which is bounded on the circumference by driven press rolls 6. The stalk material 7 to be wound up and compacted by a receiving conveyor 8 is picked up from the ground and optionally conveyed after crushing between two press rollers 6 forming an inlet 9 into the pressing chamber, when the round baler attached to a tractor by means of a drawbar 10 passes over the Halmgut lying on a field is pulled.
The drive of the press rolls 6 takes place in a conventional manner via a PTO not shown for reasons of clarity, wherein the individual press rolls 6 can be provided, for example, with sprockets which can be driven by a chain and are provided outside the press chamber. Due to this press roller drive, the stalk material introduced into the pressing chamber via the receiving conveyor 8 is first conveyed to the press rollers 6 of the ejection flap 4 by the lower press rollers 6 of the chassis-fixed housing part 3 adjoining the press chamber inlet 9 and conveyed upwards in a circulating movement by the press rollers 6 along the ejection flap 4, to be guided back down through the press rollers 6 of the Ge housing part 3. The stalk material fed via the receiving conveyor 8 is thus wound turn by turn into a straw wreath and increasingly compacted with increasing winding diameter until the finished straw bale 7 is covered by a foil or a net in order to hold the stalk material in the form of a compacted straw bale 7. The sheath 11 provided in the sheath is conventionally inserted into the press chamber and wound around the straw wrap before the chute flap 4 is swung open to discharge the sheathed hothia bale 7, as can be seen in FIG.
The wrapped with a sheath 11 Halmgutballen 7 rolls with open ejector 4 supported by the driven, bottom-side press rollers 6 of the chassis fixed housing part 3 through the resulting ejection opening from the press housing 2 on the floor and would continue to roll on the ground, if not for a deceleration of Halmgutballens 7 is taken care of. For this purpose, a catch stopper 12 is provided on the ejection flap, which is arranged in the region of the hinge axis 5 opposite end of the ejection flap 4 and in the runway of the ejected from the compression housing 2 Halmgutballen 7 projects when the ejector flap is pivoted in a predetermined catch position. The stalk bales 7 are therefore prevented in the gear position of the discharge flap 4 by the catch stop 12 at a rolling along the ground.
According to the illustrated embodiment, the catch stop 12 is formed by a freely rotatably mounted in side pivot levers 13 catching roller 14, which can roll on the straw Halmgutballen 7, sparing the shell. To damp the catch stop 12, the pivot lever 13 are acted upon by a damping spring 15, against the force of the pivot lever 13 are pivoted when the rolling from the press housing 2 Halmgutballen 7 to the catch stop 12.
In order to release the straw bales 7 prevented by the catch stop 12 from continuing to roll along the ground, the catch stop 12 must be lifted off the straw bale 7. For this purpose, the ejection flap 4 is pivoted from the predetermined catching position further into the open position, as indicated by dash-dotted lines in FIG. 2. The round baler can then be pulled away from the deposited Flalmgutballen 7 to be ready after a closing of the discharge flap 4 for the production of a new Halmgutballens.
