    Cutters are mounted on a rotor revolving in a housing, on a machine for cutting wood into chips, deriving power from an outside such as a tractor. The rotor has spaced disc-type members (12) secured on a shaft (11), with blower vanes (16) inserted between them. The cut chips enter their intervening space through holes (14), where they engage in circular movement, under the influence of the vanes towards the blow-out opening of the machine. A counter cutter may be fixed on the housing, perpendicular to the direction of rotation of the rotor. Less effort is needed for chip working. 07G21.

    11 The invention relates to a wood shredding device using an external power source, for example a vehicle such as a tractor. The purpose of the invention is to reduce energy consumption. Fig, 1 shows a rotor, a front view with a partial section; in fig. 2 - the same, side view with a partial section; in fig. 3 is a section A-A in FIG. 2j in FIG. 4 - rotor, axonometrics; in fig. 5 - installation of a blade of a rotor, partial section; in fig. 6- additional blade device, axonometric. The wood chopping device comprises a rotor 2 mounted in the housing 1, made in the form of disks 4 and 5 fixed on the shaft 4 and 5, between which there are blower blades 6 for deflashing the chips. The blades 7 and the blades holders 8 are attached to the blade 6 and the blades 7 enter the holes 9 provided in the disk 4 of the rotor 2. The blades 7 protrude from the outer surface of the disk 4 by a distance equal to the length of the chip. The distance of the blade 7 from the disk 4 is adjusted by means of a fur, low 10, which is a bolt and nut. For adjusting the distance of the blade 7, elongated holes 11 are provided. Additional blades 12 are attached to the side plates 13 of the lower device and fit into slots 14, extruded into the blade x 6, to allow the passage of additional blades 12. One of the side plates 13 has a tractor three-point connection, and the other plate 13 carries a hopper 15 for feeding trees to the blades 7. In the lower building there is a rotor 2 supported rotatably by flange bearings. The lower part of the lower rpusa is adjacent conductive with the feeding hopper 15 mounted for protivolezvi 16 perpendicular to the direction of movement of the rotor 2. On the lower housing is set verh52 SRI housing (not shown) prikreplenny to the bottom so that may be opened at the time of operation. An air tube system is attached to the upper case to direct the chips to the trailer, pile, etc. The device has a drive (not shown), executed in the form of a vehicle. The blades 6 are offset from the radial direction of the rotor 2. This offset can be up to 80 mm. The displacement of the blower blades 6 from the radial direction. reduces the centrifugal force, creating pressure on the outer periphery of the casing, creating less friction from the shavings and as a result of this reducing the cost of power for friction. The device works as follows. The device receives motor power from a drive, for example a tractor cardan, as a result of which the rotor 2 and the blades 7 rotate. A wood shredded with a diameter of, for example, 200 mm is introduced through the feed hopper 15 into the device, so that the end abuts against the face of the disk 4 of the rotating rotor 2 and because of this rises sideways to the counter-blade 16. When the rotor 2 rotates, the blades 7 project from the chips are separated from the end of the tree. As a result of the feed direction, the position of the blade 7, the angles of the blades and other parameters, the tree is not cut as it is crushed, and there is no need to push it continuously. The chips are separated from the end of the tree between the discs 4 and 5 of the rotor 2, rotate as a result of the action of the blade 6 along the rotor to the mouth of the blower tube and are transmitted along the pipe system to the trailer. By adjusting the position of the blades 7, the chip length can be changed as required. Additional blades 12 against the outer edges of the slits 14 at the outer end of the blades cut off any branches that can be caught along with the chips.
