Cutting devices in chargers are known. They consist of fixed knives that are between attached to the conveyor elements on one side or alternately on both sides of the through opening are. There are also known such cutting devices in which the knife on the leading edge the conveyor elements are arranged. With these cutting devices, all knives are fixed. They have more of each other and also of the opposite side of the passage opening or less large distance, so that conveyed goods are sometimes difficult to cut, sometimes not at all.

Cutting devices with rotating knives that are arranged on a shaft can only be cumbersome removed and adjusted to the desired cutting lengths. There are also cutting devices known with rotating circular knives and fixed counter knives or also rotating circular knives as a counter knife. With these, too, the material to be cut must be pressed through by the conveyor elements will. Cutting devices with a reciprocating cross member have also become known, to which several straight knives are attached next to each other, depending on the desired cutting length. These cutters work with the appropriate good, z. B. fresh grass or leaves, well, fail but z. B. with dry material such as hay and straw. Furthermore, the installation of these cutting devices not possible at all loading facilities at the required location due to the cross member.

The invention aims to provide one of the disadvantages of the aforementioned known devices avoiding, very simply constructed cutting devices as the goal and contributes to this a cutting device on chargers for agricultural goods with arranged on a circle and moving knife edges according to the invention two coaxially juxtaposed, circular segment-shaped, cutting cooperating knives, one of which around its center rotates back and forth and the other stands still or performs a movement in the opposite direction. As a result of the back and forth The resulting circular movement results in a pulling cut that has a very good cutting effect results and can be further improved by appropriate tooth grinding. Here it is particularly advantageous to train both circular knife edges serrated, so that all cargo, which is fed by the conveyor elements of the loading device to the cutting device, as in a Mower knife is cut.

Since the conveyor elements are the material to be cut

feed more or less intermittently to the cutting device, it is advisable to move both knives in the conveying direction to be arranged resiliently against the action of a spring. A stop can be provided here, against which the knives rest in normal position under the action of the spring.

It is also very advantageous if there are a plurality of knives arranged next to one another Drive the same from an intermediate shaft located at a distance from these for each knife separately derive, in such a way that other moving elements, such as conveying elements for the material to be cut, between can reach through to neighboring knives. This training ensures that the knife on the most favorable point for cutting can be arranged, especially in the vicinity of the Transporting the material to be cut conveying elements.

For example, the drawing shows in
F i g. 1 shows a side view of a cutting device according to the invention on a loading wagon and in FIG

F i g. 2 shows a plan view of the device according to FIG. 1 with two arranged side by side Cutting devices.

Conveyor elements 2 grip through the upper wall 1 of the conveyor channel of a loading wagon and convey the load in the direction of the arrow against moving knives 3 and stationary knives 4. In point 5 is the knife 3 rotatably mounted and the knife 4 held. Both are pressed against each other by a spring 6, to ensure a safe cut. The knife 3 is driven by a crank pin 7 and connecting rod 8 via an oscillating shaft 9. Located on the oscillating shaft 9 as many swing arms 10 as cutting devices are needed as a maximum. In point 11 of the Swing arms 10 are hinged to easily detachable rods 12, which are articulated to knives 3 at 13 are. The fixed knife 4 can at the

upper wall 1 of the conveyor channel are rigidly attached; however, they are advantageously articulated in point 14 and kept easy to remove. A coil spring 15 presses a pin 16 in the normal position, the is firmly connected to the knife 4, against a stop 17. If the pressure by the cargo too large against the knives 3 and 4, both give way by pivoting about the axes 13 and 14 at the top in the direction of arrow 18. When the conveyor elements 2 return, the knives cut freely and are brought back into the normal position by the helical spring 15.

Claims (5)

Patent claims: 1. Cutting device on chargers for agricultural goods with arranged on a circle and moving knife edges, characterized by two coaxially juxtaposed, circular segment-shaped, cutting cooperating knives (3, 4), one of which (3) around its center (5) rotates back and forth and the other (4) stands still or performs a movement in the opposite direction. 2. Cutting device according to claim 1, characterized in that both knives (3, 4) are toothed. 3. Cutting device according to claim 1 or 2, characterized in that both knives (3, 4) are arranged resiliently in the conveying direction against the action of a spring (15). 4. Cutting device according to claim 3, characterized by a stop (17) against which the knives (3, 4) rest in the normal position under the action of the spring (15). 5. Cutting device according to claim 1 or one of the following, characterized in that in the case of a plurality of knives (3, 4) arranged next to one another, the drive of one of this distant intermediate shaft (9) is derived separately for each knife (3, 4), in such a way, that other moving elements, such as conveyor elements (2) for the material to be cut, between can reach through to neighboring knives.
