CPuz.-f The invention relates to the woodworking industry, in particular to equipment for shredding wood. By ochOBHqMy auth.St. No. 950529 is a known disk chipper, comprising a casing, a boot cartridge, a blade disk with foot windows, hollow blade with slits, mounted above the additional windows ij. However, in a known machine, the cavity of the blade is rectangular in shape, the same section along the entire length of the blade, and the number of fine fractions of chips passing through the slots at the end of the blade cavity is much larger than at its beginning, since the fine fractions also they pass to the end of the cavity of the scapula, which leads to its clogging in small fractions due to their untimely withdrawal from it. In addition, the perpendicular arrangement of the inner walls of the blade to the plane of the disk, which are hit by small fractions, while losing kinetic energy, creates a variety of air turbulence in the cavity, which also leads to untimely withdrawal of small fractions of chips, reducing its quality. The purpose of the invention is to improve the quality of the fractional composition of chips. The goal is achieved by the fact that the cavities of the blades are made with a variable cross-section along the length and length, with the rear walls of the cavities of the blades located inclined to the plane of the disk. In addition, the upper and lower cavities of each 1st blade are inclined to the plane of the disk. FIG. 1 shows a car, a general view; in fig. 2 shows section A-i in FIG. one; in fig. 3 shows a section BB in FIG. 1, in FIG. 4 shows a section B-B in FIG. 3. The disk chipper for chip production includes a casing 1 with a chamber 2 for chips and a chamber 3 for Fine fractions, a boot cartridge 4 a blade disk 5 with a plane 6, knives 7, foot openings 8, hollow blades 9 with cavities 10 mounted over additional windows 11 located at the periphery of the disk 5. The cavities 10 of the blades 9 are made of variable section, i.e. extending from the center to the periphery of the disk 5. The back wall 12 of the cavity 10 is inclined to the plane b of the disk 5, and the top 13 and lower 14 walls of the cavity 10 are also inclined to the plane b of the disk 5. Slots 15 are made in the hollow blades 9. Cameras 2 and 3 are equipped with respectively discharge pipes 16 and 17. The machine operates as follows. By activating the drive, the blade disc 5 is driven into rotation. Through the loading cartridge 4, the wood is fed into the zone of action of the knives 7, where it is crushed into chips, which is discharged through the foot openings 8 into chamber 2. Next, the chips fall onto the surface of the hollow blades 9 with slots 15 and slide along it from the center of the blade disk 5 to its periphery along slots 15, through which the fines and debris are fed into the cavity 10, expanding to the periphery of the disk 5, where they hit the walls 14, 13 and 12. cavity 10, fly out through additional windows 11 into chamber 3, from where they are diverted through the discharge nipple 17. Conditioned chips, more round As compared with the small fractions that do not pass through the slots 15, they are diverted through the discharge port 16. The cavity of the variable section blade, i.e. expanding from the center to the periphery of the disk, and the inclined position of the rear, upper and lower walls to the plane of the disk exclude air turbulence and cavity fines and debris, which leads to their timely exit from the cavity of the blade and, thus, improves the quality of fractional composition wood chips.
