Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a roll baler for cereals, comprising rollers, belts, chains, etc., the range of which is limited by a compression chamber which remains unchanged during the compression process. of the type constituted by a driven conveying member having the shape of.

PRIOR ART In this type of roll baler, the finished grain bale is wrapped and wrapped with binding thread. Before the tying process begins, the advance of the machine is stopped, so that the flow of grain into the machine is interrupted. Relatively long interruptions in operation are required from forward stopping to resumption after the bail has been discharged. For this reason, it has already been proposed to arrange a grain storage space in front of roll balers of this type to enable continuous operation, ie uninterrupted advance during the bundling process.

A disadvantage of roll bailers constructed in this way is that the storage capacity of the storage chamber, which is predetermined by the bundling time, has an adverse effect on the size of the machine. However, the penetration of stored grain into the compression chamber, especially during relatively long binding times, can lead to serious operational malfunctions. In order to reduce the tying time and interruptions in operation, it has been found to be advantageous to use a covering with a strip of net fabric instead of the thread tying described above. However, continuous operation of the machine is no longer possible.

Problem to be Solved by the Invention The object of the invention is to provide a grain storage chamber that is as small as possible in order to avoid inconvenient constructions and to prevent operational failures due to stored grain entering the compression chamber. It is an object of the present invention to provide a continuously operating roller bailer.

Means for Solving the Problems The means of the present invention for solving the above problems are as follows:
In a roll baler of the type mentioned at the outset, the known means are combined to cut the formed roll bale into strips of net fabric, which consist of a bundled net roll, a net tweed roller and a cutting device. A binding device is provided for tying the outer sheathing material, and the overlapping end pieces of the net fabric are attached to the area of the net fabric located below and, if necessary, to the protruding grains. A grain storage chamber is arranged in front of the compression chamber for storing the grain during the bundling and discharge process, and the grain storage chamber can be separated from the compression chamber by a restraining and conveying member. It is possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The housing parts 1, 2 of the machine are hinged together at the side walls via a connecting member 3. The casing part 1 is arranged stationary in the machine frame, and the casing part 2 is connected to a piston-cylinder unit 5.
can be turned in the direction shown by arrow 4. The compression chamber 6 is delimited by annularly arranged rollers 7 running one after the other. Grain 8 is fed via a pick-up drum 9. The pick-up drum 9 constitutes the lower boundary of the grain storage room 11, which is limited in its lateral extent to the machine by a wall 12 and above by a grid or the like 13. has been done. A controlled raking member is arranged between the pick-up drum 9 and the supply port 14, and the raking member 15 feeds the grain into the compression chamber 6. A binding device 16 is supported in the casing part 1 in the vicinity of a roller 7 that delimits the compression chamber 6 . The binding device 17 mainly includes a tank 18 for holding the bundled net roll 17, a net guide member 19, a pair of net feed rollers 20, and a cutting device 21. As soon as a sufficiently compressed bale 23 has been created in the compression chamber 6, the tying process is started automatically or manually by the tractor operator depending on the compression pressure. A binding net 24, which is a net fabric, is fed by the net feed roller 20 through the gap 25 between two adjacent rollers 7 to the outer peripheral surface of the bail 23, and is carried by the bail 23. Ru. The supply of grain is stopped before the entered end of the bundling net 24 reaches the feed opening 14; this stop occurs after the teeth 22 of the raking member 15 have completed the bundling process and the bale has been released. This is done by remaining in the upper position until the compression chamber 6 is closed again. During the period of inactivity of the raking member 15, the grain received by the pick-up drum 9 is allowed to remain in the grain storage chamber and is then fed in a mass into the compression chamber for the formation of a new bale.

Effects of the invention By configuring the roll baler according to the invention, a continuously operated machine with the smallest possible grain storage space is obtained, while avoiding disadvantageous configurations and storing grains. Operation failures due to grain entering the compression chamber are prevented.
