Drive shaft 10 one end secured in the cover 12, the other to on the platform 34, and on the drive shaft 10 perpendicular to its axis there is a fixed blade 1 and a blade of the knife block 25, 26, 27. The blade of the single blade 1 is formed by a notch in the disk and is made in the shape of a disk sector (the rest is actually the notch and the arcuate jumper ), and the cutting edge 32 of a single knife is made of a concave shape (Fig. 6), at the end of the blade of a single knife 1 in the center of the disk is made a flange 8 (Fig. 1), and the opposite end is made in one piece with an arcuate jumper formed by the same notch . Under the blade of the single knife 1, the first holding disc 9 is mounted on the same drive shaft 10 as the single knife, at a distance equal to the thickness of the food product being cut. Between the single knife 1 and the first holding disc 9 is installed the sleeve 16. The blade of the single knife 1 and the holding disc 9 pass between the first and second guides 4,5. For the blade of a single knife 1 and the first holding disc 9 in the guides 4,5 there are separate grooves. On the rack 11 fixed two stops 2, 3 for the cut food product with a gap for the passage of the knife, provided by the thickness of the pads 7 (Fig. 3), placed between the stops. In the first holding disc 9, a cutout is made that follows the shape of the blade of a single knife. The blades of blades 25, 26, 27, in the block are formed by recesses in the discs and are made in the form of disc sectors, m cutting edges of the knives in the block (m = 1.2 ...) are concave, flanges are made at the ends of the blades blades, and opposite ends are made in one piece with arcuate bridges formed by the same notches. The cutting edges of each knife 26, 27, in the block are offset circumferentially in the direction of the axis of the drive shaft relative to the edges of the knives of the previous discs (the cutting edge of the knife 26 in the block is offset circumferentially relative to the edge of the knife 25 of the previous disc, the cutting edge of the knife 27 in the block is offset from the edge knife 26 previous disk), located above, at a distance less than the specified thickness of the product being cut. On the rack 11, parallel to the blades of the knives are placed k + 1 flat stops 13, where k is the number of disks in the block, flat stops 13 are installed between the disks of the knife block, the last disk of the knife block and the second holding disk and fixed, for example, on the rack 11. Under the first a holding disk 9 between it and the knife block 25, 26, 27 houses a hopper 17 (FIG. 5), inside which a drum with blades 18 and a conveyor 19 are placed so that the straight line passing through the axes of rotation of the conveyor shaft and the axis of rotation of the conveyor roller passes under given angle to the axis of the drive shaft 10. A second holding disk 28 with notches in the amount of m is installed under the knife block, above which the blades of the blades 25, 26, 27 are placed, respectively. A receiving tank 31 is placed under the second holding disc 28. A third guide 20 is installed under the drum with blades 18 in the central zone of the bunker, and below it is a swivel pressure plate 21. Between the single blade 1 and the first holding disc 9 is installed a sleeve 16. Between the knives in the block and the second holding disc mounted sleeve 29.

The conveyor is driven by an electric drive that transmits torque through sprocket 22 placed on the conveyor shaft, bevel gear 24, placed on the drive shaft 10, and hopper gear 23 mounted on the conveyor shaft.

The blade with the help of flanges 8 and sleeves 16 are rigidly fastened to the first holding disc 9.

In the presence of a larger number of loading receiving tanks, stops and bins, they are installed in parallel (each under each).

The device operates as follows:

The product to be cut, for example a vegetable, is placed in the loading container 15 on the first holding disc 9, having a cutout located under the blade of the single knife 1. When the first holding disc 9 rotates, the vegetable is held in the loading container 15 by the upper stop 2. The cutting edge of the single knife fits to the vegetable , cuts off a circle that falls under a single knife, where at this moment the cutout of the first holding disc 9 is located, and falls into the bunker. The whole vegetable is kept from horizontal movement by the upper stop 2. After cutting, the circle falls into the hopper 17 (Fig. 5), and the rest of the vegetable remains on the blade of the knife. When you turn the knife, it goes between the stops 2,3, and the uncut portion of the vegetable moves to the first holding disc. The knife passes a full turn, the cutting edge goes to the vegetable lying on the first holding disc and the cutting process repeats. In this operation, only a single knife is involved. After falling into the bunker 17, a circle, with the help of a drum with blades 18 and a conveyor 19, turns vertically and is aligned with a rotating presser bar 21 located under the drum with blades and a third guide 20.

The circle comes out of the hopper and lowers onto the second holding disc 28. The cutting edges of the knives 25, 26, 27 fit in the block, in which the disks with the blades 25, 26, 27 and the second holding disc 28 are rigidly fixed to each other. The first knife cuts the bottom knife 27, when it finishes cutting, the middle knife begins to cut. When the middle finishes, the upper knife begins to cut, the web width of which exceeds the width of the knives located below, not exceeding 360 °: 2m, where m is the number of cutting edges (m = 1.2 ...). Each knife passes between two flat stops 13. One knife has not yet broken, the other is already engaged with the vegetable. The whole part of the plate (circle) first rests on the canvas of the upper knife and does not fall down. When turning the knives go through the flat stops 13, the plate is cut into straws and the straw falls through a cutout in the second holding disc under the knives into the receiving container. The knives block goes through a part of the circle, the next sectors with knives fit the vegetable and the cutting process is repeated.

All knives rotate from the drive shaft, drive and motor. From the drive shaft torque is also transmitted to the hopper gear and bevel gear.

The product being cut, for example, a vegetable, moves vertically downwards and is fed under a knife blade rotating in a horizontal plane. The cut plate, falling under the blade of the knife through a cutout in the holding disc, falls into the hopper, and the remaining uncut part of the product slides along the blade of the knife, which keeps it from falling down; then the knife goes behind the stops, and the vegetable moves along the holding disc, which prevents the product from falling in the loading container. The cut plate is cut with knives in a block on a straw, which falls into the receiving container.

One receiving tank is installed under the loading tank, other receiving tanks can be installed under additional loading tanks, distributed evenly around the circumference of the vegetable cutter, and along with bunkers installed under the first holding disc, can be used simultaneously for cutting vegetables.

Thus, the invention provides technical results, and, namely, the implementation of continuous high-quality cutting of the product, eliminating jamming and divergence of knives.
