In known embodiments of such presses, large amounts of force must be used. The disadvantage has also been found that the crop is still being moved within the press cells,

Accordingly, the object of the invention is to provide an improved To create field forage cake press / in the relatively little. Force is required to move the crop in and through the press cells. press. "..

Another object of the invention is that the crop is no longer moved within the press lines, but only in the Cells are introduced and pressed out again.

To solve the aforementioned problem, press rollers are provided which have a diameter larger than half the diameter the bale chamber. This result is achieved with the help of inclined roller bearings, which make it possible to move the rollers into position partially overlapping arrangement. The press rollers are provided with bevelled outer surfaces so that their Outer surfaces aligned with the entry plane of the press cells which ensures perfect pressing into the cells is. . *

An embodiment of the press designed according to the invention is shown in the drawings. .

The field forage cake press shown here contains, as is the case with these Machines is common / a device for. Cutting and blending the Harvested material and a feed device for the material prepared in this way in the press. The recording and cutting device is not shown in the drawings. Suffice it to say that this device the cut and mixed goods through a chute Ϊ0 into one Receiving container 12 leads from which it is denoted by 14 actual press is continued. The field forage cake press 14 contains a number of press cells 16. The prepared crop is brought near the entry ends of the press cells 16 and from there continuously pressed into the lines. This makes the good within of cells transformed into a compact mass. As more and more - crop is pushed into the cells, the crop emerges from the Exit end of cells from where cakes of a certain length are cut.

In the embodiment shown, the individual parts which form the press cells 16 of the forage cake press 14 consist of side plates 18 and 20 and partition walls 22. As shown, the side plates 18, 20 are spaced apart and parallel to one another, and the partition walls 22 are attached between the spaced plates. The panels are held in place by a suitable device (such as bolts, not shown). The insides of the side panels 18, 20 thus form the transverse walls

of the press cells 16 and the inner sides of the partition walls 22, the longitudinal walls the press cells.

In the illustrated feed cake press 14, the cells are radial and arranged in a ring, with the inner or entry ends the inner circumference of the inlet and its outlet ends form the outer circumference of the same. The space between the inner periphery of the ring of press cells forms the press chamber 24. At the entry end of the press cells.16, the partition walls 22 taper to blades 26. The Cutting edges 26 are preferably made of hardened metal.

The loose mass of the shredded crop is removed from the container 12 introduced into the pressing chamber 24. There is an inlet opening 28 in the right side wall of the chamber.

For forwarding the crop from the container 12 through the opening 28, the machine shown includes a screw conveyor 30. As shown in Fig. 1, the screw conveyor 30 consists of two screws 32a and 32b, which sit rigidly on a shaft 34. The final pages the screw conveyor are provided with blades 36 which are arcuate are and extend into the pressing chamber 24 in order to forward the crop to the vicinity of the entry ends of the pressing cells 16 to make. The right end of the shaft 34 is in one The bearing 38 is rotatably arranged and is mounted on the right wall of the storage container 12, as shown in FIG. The wave 34 extends through the receptacle 12 and lies to the middle->

rotatably arranged in a bearing 42. This bearing is in the side plate 20 of the pressing device 14 attached, which the outside the pressing chamber 24 forms.

Preferably, the screw conveyor 30 ″ is relatively high Rotated speed so that they just didn't get the crushed out The harvested crop coming from the container 12 is conveyed further into the pressing chamber 24, but the crop at the same time in a whirling motion offset so that it is centrifugal on the entire periphery of the bale chamber is distributed over the inlet ends of the press cells 16.

The crop that has been distributed in the press chamber 24 is then continuously pressed into the press cells 16 and pressed against the blades 26 in order to cut off the part of the crop that is pressed into adjacent press cells The feed cake press 14 shown uses a pair of pressure rollers 50 of considerable mass and as large as possible. The rollers 50 are carried by a support frame which includes a pair of arms 52 and 54 extending diametrically opposite each other, which are arranged in the pressing chamber 24 and connected in a rotationally fixed manner to the shaft 34 and the stub shaft 40, respectively. As shown in FIGS. 1 and 2, each of the rollers 50 is circular and sits on a shaft 56. The two shafts 56 lie between the outer ends of the arms 52 and 54. The rollers 50 are placed so that the outer surfaces of the rollers come together Describe the movement path, which is close to but at a small distance from the periphery of the eating chamber

is located at the egg entry end of the press cells 16 through the cutting is formed.

The invention provides a pair of opposing pressure rollers 50 to use, each of which has a diameter which is greater than half the diameter of the pressing chamber 24, if this is measured via the entry end of the press cells 16. As As shown in Fig. 2, the large scope of the rollers makes it possible to harvest crops in and through several adjacent ones at the same time To press press cells i6. In addition, the large roll diameter enables the use of a relatively short crank arm, which by the distance from the axis of the shafts 34, 40 to the axis of shafts 56 is determined. The use of the named items makes it possible for more crop to be pressed by the rollers 50 through the press cells 16 with less force than is the case with known ones Forage cake presses with smaller pressure rollers is possible.

In order to be able to use the large pressure rollers 50 according to the invention in the pressing chamber 24, the shafts 56 carrying the rollers are inclined at an angle in relation to the axis of the shaft 34. The rollers 50 are rotatably arranged in bearings 58 on the inclined shafts 56 so that the rollers have an angle of inclination in. Relation to the shafts 34, 40 which enables the rollers in the press chamber 24 to be arranged in a partially overlapping manner, but with a common orbital path near the entry end & e of the press cells (Fig. 1) described

10-8809 / 0487

Furthermore, according to the invention, the surfaces of the rollers 50 beveled, as indicated at 60 (Fig. 1), the bevel angle is substantially equal to the angle of inclination of the shafts 56 with respect to the axes of the shafts 34,40. Through this bevel of the roller surfaces, these are even with the entry send the press cells 16 aligned. This results in a clean cut des Ernteguts'between the rollers 50 and the blades and a radial pressing of the crop in and through the press cells 16 guaranteed.
