Description

The present invention relates to a device in harvesting machines of a multi-disc cutting apparatus, the discs of which are driven in rotation from the axis of the running wheels of the machine, for which, according to the essay, a common thrust is used, coupled to the driving crank.

The drawing shows a general view of the apparatus.

The system of discs 1, provided with cutting blades 2 and connected by a common bar 3, rotates horizontally from the driving crank 4, near the finger bar 5, having a contour drawn along arcs of circumferences, corresponding to the number and diameter of the discs, from the centers of the latter. The transfer of movement to the disks 1 is achieved either by HenocpeuCiBSHfro connecting the joint rod 3, with the leading curvature of the 4 or using-hinged connections. The finger bar 5 is provided with a common or divided into parts, a review on ease of manufacture, a plate 6. The finger itself can also be made from individual parts for easy replacement in case of a breakdown. It is advisable to make the number of fingers 7 of the beam 5 possible & amphibiously, in order to obtain a greater uniformity of travel, and the uniformity of the work of the whole apparatus can also be adjusted by the number of disk strings. The location of the knives on the disks is determined by the arc of the working sector of each knife, which in the case of four disks gives the location of the knives at an angle of 90 ° to each other, as shown in the drawing. The knives of the adjacent disks are attached to the latter from different sides, so that they work in different horizontal planes; The radial direction of the cutting edges of the finger bar 5 avoids double cutting of the same areas. The disks themselves can be either solid or of another kind. It is only necessary that they develop sufficient inertial forces, which in the proposed apparatus, in contrast to the modern cutting apparatus, contribute to the alignment

resistance and smooth operation of the entire system.

PRESENTATIONS.

A cutting unit for the harvesters, consisting of a system of discs with cutting blades, driven in the axis from the running axle. The wheels of the machine, characterized in that / to drive the discs, a total of 3 ha, articulated with the fingers of the discs and the leading crank is used.
