Description

 The invention relates to the field of processing vegetables and may find application in the vegetable industry.

 Known universal cutting machine "Rhythm" brand A9-KRV [1] This device is used, in particular, for cutting onions into circles. In the mode of cutting raw materials into circles, the device comprises a housing with a loading hopper and an unloading tray. A feeder in the form of a rotating rotor assembled from two disks and three blades is placed in the housing. A knife block in the form of a flat knife is reinforced in the lower part of the body. The rotor is driven by an electric motor through a gearbox. This device is taken as a prototype.

 The disadvantage of the prototype is the low quality of the resulting product. This is due to the fact that juice is extracted from the onion due to significant deformation of the onion when cutting it with a stationary flat knife. At the same time, it is practically impossible to get a circle of the same thickness over its entire diameter due to the fact that the rotor blade presses on the bulb above the cutting line and, with a significant effort of cutting with a stationary flat knife, the part of the bulb that is farthest from the knife will inevitably rise, which ultimately will lead to a decrease in the thickness of the part of the circle farthest from the knife. The unevenness of the thickness of the circle does not allow to obtain a high-quality product during drying, because the thinner part will dry faster than the thicker part of the cup.

 The invention is aimed at improving the quality of the cut product.

 The essence of the invention lies in the fact that in a device containing a housing with a loading hopper, an unloading chute permitted in the housing, the feeder and knife block, the feeder is configured as a comb and a set of agitators mounted on the first horizontal shaft under the top of the comb with the possibility the agitators pass through the first grooves of the comb, and the knife block is made in the form of a set of circular knives mounted on a second horizontal shaft with a predetermined pitch using intermediate washers above the bottom part of the comb with the possibility of the passage of circular knives through the second grooves, while between the circular knives under the intermediate washers mounted cutters attached to the body.

 In FIG. 1 shows a device for cutting onions into mugs; FIG. 2 combs, where: 1 case, 2 loading hopper, 3 loading tray, 4 feeder, 5 knife block, 6 comb, 7 agitator, 8 - the first horizontal shaft, 9 first grooves of the comb, 10 circular knife, 11 - the second horizontal shaft, 12 intermediate washer, 13 second grooves of the comb, 14 cutter, 15 tedder tray, 16 electric motor, 17 - control unit, 18 V-belt transmission, 19 gear transmission, 20 - knife block screen, 21 adjustable support.

 A device for cutting onions into circles contains a housing 1 with a loading hopper 2 and an unloading tray 3. In the housing 1 there is a feeder 4 and a knife block 5. The feeder 4 is made in the form of a comb mounted with an inclination in the housing 1, and a set of agitators 7 made in the form of an impeller with blades. The agitators 7 are installed with a given step on the first horizontal shaft 8 under the upper part of the comb 6 with the possibility of the blades of agitators 7 passing through the first grooves 9 of the comb 6. The width of the first grooves 9 of the comb 6 does not exceed the minimum size of the bulbs used for processing. The knife block 5 is made in the form of a set of circular knives 10 mounted on the second horizontal shaft 11 with this step using intermediate washers 12 under the lower part of the comb 6 with the possibility of passage of the circular knives 10 through the second grooves 13 of the comb 6. Between the circular knives 10 under the intermediate washers 12 mounted cutters 14 attached to the housing 1.

 In the lower part of the housing 1, made in the form of a frame, under the first grooves 9 of the comb 6 is installed tray 15 agitator. The second horizontal shaft 11 of the blade knives 10 is driven from the electric motor 16 by means of a V-belt drive 18. The first horizontal shaft 8 of the agitators 7 is driven from the second horizontal shaft 11 by means of a gear drive 19. The electric motor 16 is connected to a three-phase AC network via a control unit 17. For visual observation of the cutting process, the housing 1 is made with a rectangular window closed during operation of the device with a transparent screen of the knife block 20. The screen 20 of the knife block is installed with the possibility of opening if necessary. The housing 1 is equipped with four adjustable legs 21 from below, allowing the device to be installed in a horizontal stable position.

 In the control unit 17 is placed the electrical equipment of the electric motor 16. On the door of the control unit are the device controls: input switch "Network", the "Start" and "Stop" buttons. In addition, a magnetic starter is placed in the control unit 17, which includes an electric motor 16 with its contacts. To protect the electric motor from overloads, an electrothermal current relay is used. When the motor 16 is overloaded, the relay opens the control circuit with its contact, a magnetic starter coil is provided, which disconnects the motor 16 from the network with its contacts. The device provides for locking the door of the control unit 17 and the screen 20 of the knife block. When the door of the control unit 17 or (and) the screen of the knife block is not closed, the electric motor 16 does not turn on, because the contacts of the corresponding microswitches of these nodes are in the open state. When the door of the control unit 17 or (and) the screen of the knife block is closed, the contacts of the corresponding microswitches of these nodes are in a closed state.

 A device for cutting onions into circles works as follows.

 Make sure that the screen 20 of the knife block and the door of the control unit 17 are closed. Connect the device to a three-phase AC network and set the mains "Network" switch to the "ON" position. The electric motor 16 is turned on by the Start button. Disk knives 10 receive rotation through a V-belt drive 18. The agitator 7 receive rotation towards the disk knives 10 through a gear 19 from the second horizontal shaft 11. The peeled onions prepared for cutting are poured into the loading hopper 2. Under the action of a set of agitators 7 and the force of its own weight, the onion falls onto the rotating circular knives 10 and is cut into circles with a thickness equal to the specified step for installing the circular knives 10. The cut onion circles are pinched between with circular knives 10 and moved in the direction of the discharge tray 3. Under the action of centrifugal forces, the onion cups fall from the knife block 5 into the discharge tray 3 and fall into the removable container installed underneath. Stuck between the circular knives 10, the onion mugs are pushed out of the knives by the cutters 14 and also fall into the discharge tray 3. The onion mugs have a thickness equal to the installation step of the circular knives 10 over the entire diameter of the circle. Pieces of onion that fell during the cutting through the first grooves 9 under the comb 6 are removed from the device using the agitator tray 15 in a container installed in the lower part of the body, made in the form of a frame. The operator has the opportunity to observe the cutting process through the transparent screen 20 of the knife block and, if necessary, can quickly turn off the device by opening the knife screen or pressing the "Stop" button. After cutting is completed, you must press the Stop button and turn the mains "Network" switch to the "OFF" position. on the front door of the control unit 17.

 When performing circular knives 10 with a thickness of 1, 2 mm and installing them on the second horizontal shaft 11 with a step of 4 mm (the thickness of the intermediate washers 12 is 2.8 mm), circles of constant thickness of 4 mm can be obtained.

 Thus, the claimed device provides high quality cut product by obtaining onion circles of constant required thickness with insignificant losses onion juice when cutting.
