    The invention relates to agricultural machines, in particular to forage machines. The purpose of the invention is to reduce the laboriousness of installing the U 16 drum by improving the accessibility of the connection points on the inner disk of the drum. For this, the inner drum discs 3 are larger than the outer drum discs 2 and the outer circumferential circle 13 of the inner drum discs 3. on which the connecting holes 11 for the flange 6 are located are placed outside the circumference of the outer drum disc 2. On the inner pitch circle 14 on the inner drum discs 3, bolts 15 are fastened through which the flanges 6 are connected with the recess 17 and whose vanishing lines with internal connecting holes 11 in the outer drum disk 2 parallel to the axis of the drum shaft 1.2 head. .f BACKGROUND yl 2. / J ё sl о о о V4

    The invention relates to agricultural machines, in particular to forage machines.
    Known grinding drum auth.St. USSR № 175778, cl. A 01 D 43/08, 1964, comprising knives located on the holders, side plates with attachment points.
    The disadvantage of this drum is the inaccessibility of the attachment points of the knives.
    The purpose of the invention is to reduce the laboriousness of mounting the drum by improving the accessibility of the joints on the inner disk of the drum.
    Figure 1 shows the chopping drum, side view; Fig, 2 - the same, front view.
    On the drum shaft 1, two external drum disks 2 and one internal drum disk 3 are mounted parallel to each other. At the same time, the diameter of the internal drum disk 3 is larger than the diameter of the external drum disks 2. Between the drum disks 2, the knife holders 4 are strengthened through flat flanges 5 and 6 , the knife holders 4 protrude beyond the drum disks 2 and 3. The knife holders 4 have in their front edge passing inward swiveling blades 7, which on both sides opposite to the working direction of rotation are arrow-shaped view. On the upper side of the knife holders 4, the chopping knives 8 are connected in such a way that they follow the sweep and, protruding beyond the outer drum disks 2, form in the middle a short intersection zone.
    To connect the flanges 5 and 6 to the drum disks 2 and 3, the external drum disks 2 have on the outer circumference circumferential circle 9 and the inner pitch circumference 10 connecting holes 11. The adjacent flanges 5 have a corresponding hole shape, and for each flange 5 two connecting holes 12 on the outer pitch circle 9 and one connecting hole 12 on the inner pitch circle 10. On the inner drum 3 there is an internal pitch circle 13 so that its diameter is larger than the internal diameter of the outer drum disks 2. At this
    pitch circle 13 for each flange b there are respectively two connecting holes 11. On the inner pitch circle 14 of the inner drum disc 3, having the same diameter as the inner pitch circles 10 of the outer drum disc 12, bolts 15 are mounted on both sides. Flanges 5 and 6 fit on the drum
    discs 2 and 3, moreover, a threaded joint 16 is formed between the three outer and two inner connecting holes 11 and 12, the inner flange 6 is displaced in the working direction
    rotation of the recess 17 on the bolt 15. The connecting holes 12 and the recess 17 are located in the flanges 5 and 6 so that the front edge of the chopping knife 8 has a constant distance along its entire length
    relative to the circumference of the drum shaft 1 or its axis of rotation.

    Claims (3)
    [1]
    Claim 1. The chopping drum of agricultural machines containing chopping knives, knife holders with side plates fixed with bolts on the outer and inner disks of the drum, with fastening holes in each disk of the drum, located on the outer and inner circles, differing in that, in order to reduce the complexity of mounting the drum by improving the accessibility of the joints on the inner disk of the drum, the latter is made with a larger diameter with respect to the outer drum scum, the radius of the outer circumference of the inner disk outer circumference greater than the radius of outer discs, and the side
    plate holders mounted on the inner disk, made with a notch that interacts with the fastening element located on its inner circumference.
    [2]
    2. A drum according to claim 1, characterized in that the recess is made with the opening c. direction of rotation of the chopping drum.
    [3]
    3. The drum of claim 1, which is different
    The fact that the mounting holes of the knife holders, located on the inner circumference of the outer and inner disks, are made at the same distance from the axis of the drum shaft.
