The invention relates to a feed cake press, in particular for fibrous feed, for example Hay, the outwardly tapering baling channels arranged radially on the circumference of a cylinder and having at least one roller rotatably arranged in the cylinder on a carrier and is equipped with a screw conveying the feed into the cylinder.

In addition to fodder cake presses, the material to be pressed is pressed together in press channels by means of pistons is also known at the outset, the opposite piston presses require a significantly lower structural effort. In the known presses the introductory described embodiment, a rotating press roll is arranged in the cylinder, which is on her Circumference at close spacings parallel to its axis of rotation arranged knife, which the task have to compress the fibrous material to be compressed into feed cake, such as hay or the like, very fine too cut up before it enters the press channels under the action of the pressure exerted by the roller is pressed in, which open into the cylinder space.

In the aforementioned design of the press, a structurally complex design of the press roll, which carries the cutting knife is required, and it must be of the press roll to the desired very fine comminution of the material and the force required to press the material in or out. are transmitted from the drive to the roller, whereby the power-sapping fine shredding of the material still has the disadvantage that a considerable part of the finely chopped material, as it is only difficult to be grasped by the roller and pressed into the press channels, initially several times is moved around by the press roll in the cylinder before it enters the press channels. Through this not only does the power requirement of the press increase, but there are also clusters and thereby malfunctions caused.

The object of the invention is to provide a feed cake press of the type described above To make the familiar in their structure easier and to train so that with low drive power Trouble-free operation is guaranteed without reducing the pressing pressure.

To solve the above problem, the new fodder cake press according to the invention is characterized in that the partitions of the press channels run out against the interior of the cylinder in sharp edges to prevent the fodder cake press through the roller against them, especially for fibrous ones

to cut up pressed fodder and to guide it into the baling channels.

In the new design of the press, the press rolls are not at the same time carriers of cutting knives, but the comminution of the goods takes place by pressing it against the of the Separating walls formed between the compression channels cutting edges. This achieves that only a subdivision of the supplied goods into sections takes place that correspond to the dimensions of the inlet cross-sections corresponds to the pressing channels, so that practically the entire, exerted by the rollers Force is available for pressing the material into the channels. This will be a very fine one Fragmentation of the property, which can lead to the above-mentioned difficulties, avoided, and you also achieves an improved cohesion of the feed cakes, since the very finely chopped ones Particles do not tend to tangle to the same extent as the longer ones produced according to the invention Sections that are adapted to the dimensions of the inlet cross-sections of the passageways.

To ensure that the pressed material is distributed as evenly as possible and that favors trouble-free operation According to the invention, it is possible to effect the compression channels emanating radially from the cylinder interior it is also provided that the screw for feeding the pressed material to the cylinder space is designed double and is driven synchronously with the roller carrier and that their outgoing ends

lie in the area outside the rollers and the roller carrier. With this configuration of the feed cake press at the same time a substantial simplification of their structure is made possible because for the Drive the worm and a common drive device for driving the roller carrier Can be used.

According to a further feature of the invention, it is useful if the roller is left a distance between its circumferential surface and the sharp co-operating with it Runs around the inner edges of the Preßkanalwandungen. This achieves a very long service life, because the cutting edges formed by the Preßkanalwandungen are not damaged, and it there is no significant wear of the press rolls. An impairment of the cutting process is do not worry if the distance between the surface of the press roll and the Cutting edge is kept low, as the pressing pressure from the roller on the between these and the cutting edge is transferred to the latter to a sufficient extent to the To separate the cutting edge of the adjoining good particles. According to the invention, the compression channels can be exchangeable be formed cell-like molds, which have the advantage that in the same press structure, adapted to the respective material to be pressed and with different cross-sections can be used. In addition, the interchangeability of the molds allows a quick replacement of any damaged cells or cutting edges.

The new press can be used for non-shredded or pre-shredded fibrous forage such as hay or the like., Use. It is recommended when the press is loaded with material that has already been shredded to connect the press directly to a forage harvester, from which the crop is forwarded to the press will.

The drawing shows an embodiment of the invention.

F i g. Figure 1 shows a longitudinal section through the fodder cake press;

F i g. 2 gives a section along the line 2-2 according to FIG. 1 again;

F i g. 3 is a side view of a die; F i g. 4 gives in the top view of the mold F i g. 3 again;

F i g. 5 shows a top view of a compression mold with a plurality of partitions.

From the F i g. 1 and 2 the basic structure of the newly designed feed cake press can be seen. The press has a housing which is used to receive and feed the pressed material, which from an end wall 10, a channel-shaped housing part 11 and from further to Above adjoining wall parts 12 is formed, wherein the wall parts 12 have a feed opening for make the good. The housing 10, 11, 12 is supported by supports 27 on which it is fastened.

The housing consisting of parts 10, 11, 12 is open on its side opposite the end wall 10 and on this side with an annular disc 13 belonging to the pressing device. Parallel and in the axial At a distance from the disk 13, a second disk 14 is provided which rotates a shaft 16 in a hub 15 records. With the shaft 16, which is driven via a drive member 26, is a double-thread Connected screw 34, 35, which extends in the longitudinal direction through the channel-shaped housing part 11 extends. On the shaft 16, two spaced apart roller carriers 29 in the form of double-armed levers are also secured against rotation arranged, wherein the roller carrier connected to one another via a sleeve-shaped spacer 28 ίο are. The roller carriers are in the area of their free ends with shafts held by them in a rotationally secure manner equipped, on which freely rotatable rollers 31 are arranged, which have a toothed peripheral surface 32 exhibit.

The annular discs 13 and 14 are mounted on a series of screws on their periphery 41 connected to each other. The screws 41 also serve to hold cell-like molds, which are made up of side or partition walls 42, end walls 43 and also serve for separation Partition walls 44 (Figs. 1, 3 and 4) exist. The molds are radially next to each other arranged on the entire circumference of the disks 13 and 14 and inclined in such a way to each other extending end faces 43 equipped that outwardly tapering compression channels form which extend up to the cylinder space required by the rollers 31 during their rotation. The partitions or partitions 42, 44 run, as the figures show, towards the interior of the the compression molds enclosed cylinder space into sharp edges, the separating partitions 44 are equipped with a specially sharpened edge 45.

Instead of dividing the molds by a single partition 44 into two channels according to FIG FIG. 4 can also show a further division of the cross section enclosed by the compression mold be provided by several partition walls 46, as shown in FIG. 5 illustrates.

By holding the molds by means of the screws 41, which are also the annular Connecting discs 13 and 14 is an easy interchangeability of the individual shapes without major Effort possible.

It can be seen from FIG. 2 that between the peripheral surfaces of the rollers 31 and the A small distance is provided in dividing or intermediate walls 42, 44 which run out from sharp edges so that the rollers cannot come into contact with the edges. The distance but is held between the rollers and the edges so that the rollers hold the material to be pressed in the area not only compress the sharp edges, but exert such hard pressure that a cutting effect is achieved.

The screws 34, 35 and the roller carrier 29 run due to their rotationally secure arrangement on the common shaft 16 synchronously around. The arrangement is such that the outgoing ends 37, 38 of the screws are always in the area outside of the rollers 31, so that the screws in Direction of arrow 36 (FIG. 1) to the pressing device in the direction shown in FIG. 2 labeled 39 and 40 Spaces of the cylinder enclosed by the molds entered without being introduced to be hindered in this cylinder space by the roller carrier 29 or rollers 31.

Like F i g. 1 shows, is with the shaft 16 via a hub-shaped part 18 and a wedge 17 yet another radial arm 19 connected, at its free end a knife holder 23 and one on a circular path around the pressing device circumferential knife 24 carries which is provided with a cutting edge 25 is. The knife holder 23 is adjustable and for this purpose with a slot 22 for the Provided passage of a retaining screw 21 which engages in a threaded hole 20 of the arm 19.

When the fodder cake press is in operation, the goods brought into the housing 10, 11, 12, for example pre-chopped hay, through the augers 34, 35 into the rooms 39, 40, in which it is from the detected rotating toothed rollers 31 and outwards into the compression channels formed by the molds is printed. The relatively hard pressure on the cutting edges results in the material being pressed of the partitions 42, 43 of the molds always in lengths corresponding to the respective entry side Press channel widths cut up. In the compression channels, the material is due to the action of pressure and pressed together by the moisture still escaping to form compact fodder cakes, whereby the good sections additionally felted, so that they are relatively firm and not prone to crumbling Strands of feed material arise. The cutting edges 45 of the partition walls 42, which converge in the shape of a wedge and the mutually inclined walls 43 of the molds have a particularly compacting effect the good one.

When the pressed material emerges from the molds, the rotating knife 24 in The shape of discs is continuously separated from the following strand of pellets, and the Slices of feed cake conveyed away from the press by a conveyor.

The press shown in the figures can be used for fibrous feed that is already are pre-chopped. But it is also suitable in the same way Way for processing goods that have not yet been crushed before being fed.
