"Baler for fibrous grass"

In baling presses, the fibrous material is generally first a prepress with relatively low pressure and then in one and the same press box one Subsequent pressing with significantly higher pressure. Of the Press box is pivotable for this purpose, so that he was first in the area of a pre-press ram and then be brought into the area of a post-press ram can. Usually several, at least two, press boxes are provided, so that the pre-pressing takes place in one box takes place while the goods located in the second box is re-pressed at the same time.

The walls of the press boxes are formed by doors, which are interlocked with special locks until the bale is finished. dia haiiptsäclilleh on - "based on - that d © r completes® BsI = X © n laataa? sete © ^ ©" blieheia Dru @ ls. st © iLt _s © 0 && B di © beis

So you have two separate locking means are provided, one of which consists of a simple tendon lock that locks the doors against each other until you start to press the lock, while the other is made up of one outside the boxes, there is a hydraulically operated ram which - attacking the doors from the outside - prevents the doors from opening, while at the same time the simple snap lock is released (German Patent 1 224 148), so that however the structure of the press is very intricate.

The invention is based on the stated object Solve problem in an easier way. In contrast to the known solution, the invention only serves a single locking element that takes over the door locking both when pre-pressing and when re-pressing «,

Naehpreßseite the press arranged drive in and out Intervention with locking cams that are always on the doors can be brought. One and the same closure piece thus locks the doors during the two pressing phases and will only be used after the bale has been completed .; so afterwards after pressing, removed by the drive. The drive can be done by hand. The preferred execution however, a pneumatic or hydraulic one corresponds to the invention Drive because the removal of the breechblock generally requires a relatively large amount of force.

The engagement of the closure piece with the to Locks located in the doors can be secured by a form fit “Instead, it can also be secured by magnetic force,

■ Are in the preferred embodiment of the invention the Versöhlußstück and / or the cams at the transition from the closed position to the open position and vice versa with inclined surfaces next to each other, so that the opening of the (yours takes place smoothly and the doors * also when they open after Completion of a full press cycle have not been completely slammed, from the breech piece perfectly can be brought into the closed position.

The connection of the locking piece to the movable part of the drive is preferably designed in such a way that that the press boxes can easily be

Once can to connect the closure piece with the movable part of the drive laterally open, the pivoting movement of the boxes is provided claws be. On the other hand, the connection of the closure piece with the moving part of the drive done by magnetic force.
