FIELD: woodworking industry :,

The purpose of the invention is to increase the quality of conditional chips with pre-crunch-f. AI large waste about

The device is shown on the fig. longitudinal section, in FIG. 2, section A-A in FIG, fng, 3 view B in FIG. 1, without the machine cover),

The device consists of impellers I of the knife drum 2 enclosing it, coaxially mounted in the casing 3, equipped with a loading box 4 n with a cartridge chuck: its output is crushed chips (not shown),

The krytchatka 1 is equipped with axial billes 5 and radial blades bd fixed by the slats 7 on additional blades x 8 that 20 are rigidly connected to the impeller 1 wall the bases 12 with counter knives 13 and cover strips 14b. The bases 12 are connected to each other by means of a central flap 15 and have a triangular cross-section, the top of which is directed to the side of the hopper 4 Radial knives 6 and the counter blades 13 ozheny angle | to the radius of the spinning of the impeller 1 and the knife drum 2, respectively, the cutting of the chips occurs at the time of the meeting between the radical 1HX iozhi 6 and the cocktails 13,

The device works as follows.

Large chip waste was fed through the loading hopper 4 into the body 3 into the inner space of the harvester 1 "Dpina pieces more than 2/3 of the width of the NB 2 are pre-cut with additional radial knives 6 and counter-blades, the angle of inclination 6 12 ° of which provides cutting on the front scissors. The chips that have passed inside the impeller 1 are discarded to the knives 9 and NB 2 is removed to the chuck to remove the chopped chips, 3 sludge.

The knife drum 2 and the Krtikchatka 1 aligned with it rotate inside the housing 3 in opposite directions at different speeds. The coarse sorting waste of the technological chips to be crushed is fed through the hopper 4 into the casing 3, where they fall into the inner space of the impeller 1. The pieces less than 2/3 the width of the knife drum 2 are free and pieces of dpina more than 2/3 the width of the knife drum 2 are pre-cut with the help of radial knives of the 6 n counter-knife I3j, the angle of inclination of which 6-12® provides for the cutting of the gogo-dip of the shears.

The chips passing inside the chip 1 are pushed by the rotating impeller 1 into the peripheral zone and are pressed to the inner plane of the knife drum 2 by the action of centrifugal force. The chip 15 moves the chips along its circumference during rotation, resulting in a meeting with the protruding part of the blade 9 of the chip 9 the wood which, through the foot gap, flies out of the cutting zone and is removed from the device through the opening in its base to remove the crushed chips (not shown).

When chipping is minimized, the semi-electric blades 8 of the wheel 1, designed for 1e for securing the radial blades 6, are installed perpendicular to the back wall of the roller 1 at an angle of 6-12 to the radius of the roller

1. At the same time, the angle of installation of additional blades depends on the breed and humidity of the material being processed.

To ensure the most effective cutting angle and, consequently, the lowest energy consumption, as well as for the sake of simplicity of maintenance of the device, the plane of the seats for the freezing of the radial knives on the additional blades are turned at an angle of 38-40 ° relative to the plane of cutting.

The fundamentals 12 under the counterbags 13, located opposite the additional blades 8 of the impeller 1, are rigidly connected to the flange 11 mounted on the pressure ring 10 of the knife drum 2j, which ensures both the manufacturability of the design and facilitates installation and maintenance of the device.

The connection of the bases 12 under the counter-25kni, while the device is equipped

The knives 13 interconnect each other by means of a flow around the bases, which are located on the blade 15, which provides the necessary rigidity against the additional blades and eliminates the gloves, and the cutting edges counteract the crushed chips into the blade gap in the direction of rotation between the bases 12 and the end part of the 30th drum , and the counter blades of the bale of the small cloth 1, which are unresolved in the bases connected

it would be safe to cause emergency ostano-between themselves through the dull

You are devices in connection with the ignition of the processed material, and this is unacceptable in the conditions of pulp and paper enterprises.
