The invention relates to a corn harvester with two adjacent rotating break-off rollers for the cob and concerns such a machine, in which the lower parts of the rollers for Collect the corn on the cob and use the upper parts of the rollers to separate the corn on the cob.

With such harvesters, there is a difficulty in handling the cobs after they have been are separated from the corn stalk. The machines most used at the moment are two adjacent Break-off rollers are provided, between which the corn stalks pass. Once the reels with come into contact with a part of the corn stalk carrying a piston, the corn stalk becomes wider carried out between the rollers, while the cob, due to its greater thickness, is not passes through and is thereby separated. The two rollers are arranged parallel to each other and both from near the bottom to above the level where the ears of corn get on the rollers, inclined. They are generally inclined at the same height above the ground on a transport device, on which the ears of corn fall after being severed. Due to the arrangement of the Rollers show the severed corncobs tendency to be carried along a short distance by the rollers before they are delivered to the transport facility. Loosen during disconnection often corn kernels from the cob, which in spite of the small amount in each case leads to a considerable loss can lead. Continuing to roll the severed pistons at the top of the rollers increases this loss.

In the lower area of the rollers, where the corn stalks come into contact with them in one layer, in which the pistons are to be separated from the stem, the function of the rollers is mainly in inserting the corn stalks into the device. So far it was common; to design the rollers with a diameter that tapers downwards, to facilitate the introduction of the stalks into the device. Corn stalks often lay like this into the device that already in the lower area corn cobs are in contact with the rollers come and thereby corn kernels or even corn cobs below the beginning of the transport device split off.

Bring the lower part of the two rollers near the bottom where the corn stalks are inserted Adjustment and location problems relative to the top of the rolls where the severing occurs the corn on the cob is made from the stalk. Im un corn harvester

In the lower area, a relatively larger nip is required, and preferably the rolls should be conical be executed and the width of the gap between the rollers decrease upwards. in the In the upper separation area, a different relative position of the rollers is essential, which, however, is independent of the in the introductory area

To solve these problems, a machine is known which has two beveled break-off rollers for the Having corn on the cob, the upper roller being shorter than the lower roller. Immediately before the short one A fixed guide piece is arranged on the upper roller, bent laterally against the lower roller. It is also known to form the upper roller with a removable sleeve. But also these well-known Arrangements solve the problems outlined above only to a limited extent.

In these arrangements, an independent adjustment is due to the difference between the two Areas not possible when using two adjacent rollers.

It is the object of the invention to design the roller arrangement so that a independent adjustment of the distance between the rollers at the point of introduction for the stalk on the one hand and can be reached in the separation area on the other hand.

According to the invention, the object is achieved in that a roller has a joint between its having upper part and its lower part, the upper part of the articulated roller parallel is arranged on one side of the upper part of the adjacent roller above the same, while the lower part of the articulated roller is rotatable and at an angle to the upper part
