The invention relates to a fodder cake press, in particular for comminuted, fibrous material, for example Hay, which is arranged radially on the circumference of a cylinder, tapering outwards Has compression channels and which are rotatably arranged with at least one in the cylinder on a carrier Roller and is equipped with a screw conveying the feed into the cylinder.

There are a large number of factors, the fluctuations of which have an influence on the quality of the known Exercise feed cake presses of the type mentioned produced feed cake because the known machines can not be adapted to these fluctuations. These factors include z. B. the amount of timely supplied feed, its distribution in the machine, the degree of crushing or the moisture content, etc.

The invention is based on the object of designing a press of the type mentioned at the outset in such a way that that it is largely independent of fluctuations in the factors mentioned, able to make fodder cake produce that are evenly pressed and dimensionally stable and that during subsequent transport or later storage are retained in their shape without major abrasion losses or Signs of disintegration occur.

In order to achieve this object, a press of the type mentioned at the outset is characterized according to the invention in that at least one boundary wall of each compression channel is at least partially elastic is held resilient.

This training of the press gives it an adaptability to an uneven material supply or material distribution, because the flexible walls prevent an impermissible material supply when there is a strong supply of material Increase in the baling pressure by expanding the cross-section of the baling channel by giving way, But they also prevent an inadmissible drop in the baling pressure as a result of insufficient material supply, by narrowing the cross section of the bale channel.

The adaptability of the press is increased according to a further feature of the invention, when the two boundary walls of each arranged on the circumference of the cylinder Press channel are at least partially held elastically resilient.

It is useful if the resilient wall parts hydraulically or pneumatically or mechanically operated support members are held.

The invention further provides that the support members are subjected to the same controlled pressure are.

as To achieve uniform feed cake formats the new press is characterized according to a further feature of the invention in that deflectors in a radial extension of the press channels inclined to the exit direction of the fodder cake to break off the same are arranged.

It is advantageous to connect the new baler to a forage harvester.

To promote the solution of the task mentioned in the introduction, a press is characterized by the mentioned type, preferably the new press, according to the invention further characterized in that a spray device for supplying admixtures of predetermined substances, in particular for moistening the Good before the pressing process is provided.

It is advantageous if the spray nozzles are arranged directly in front of the press cylinder.

The aforementioned training of the new press is a compensatory adjustment to numerous fluctuating influencing factors reached.

The solution to the problem set out in the introduction is the one mentioned at the beginning with a press Art, but in particular in the new press according to the invention still promoted in that a Double-start screw, driven synchronously with the beam carrier, protruding into the cylinder 'carries flange-like guide vanes for the radial supply of the material to the baling channels.

It is useful if the guide vanes end immediately in front of the press rolls.

Finally, the invention also provides that a guide vane is assigned to each roller and that d'o guide vanes as an extension of the screw ranks are trained.

An embodiment of the new press is shown in the drawings.

Tip of the funnel remains. The material is fed to the screw 32 through this opening 39. From FIG. 5 it can be seen that the screw flights of the screw conveyor 32 end in flange-like guide vanes 40. At the same end at which the flange-like guide vanes 40 are also located, a pair of supports 41 are attached to the shaft 31, at the ends of which bolts 42 are held, which serve to accommodate rotatably mounted press rollers 43,
ίο The goods coming out of the container are moved by the screw conveyor 32, distributed by the flange-like guide vanes 40 and placed in front of the rollers 43, which press them into pressing channels 47. The compression channels are open on both sides and their longitudinal axes run radially to the shaft 31. A boundary of the compression channels is formed by a side wall 44, to which a plate 48 adjoins radially outward. On the plate 48 are at a predetermined distance from the outer openings of the pressing channels 47 radial
