Description

The utility model relates to agriculture, is intended for chopping fruits and vegetables and can be used in individual farms and peasant farms, as well as in the food industry and public catering.

A known juicer feed chopper comprising a body, the wall of which is made of cutting elements mounted in the lower part of the body, arranged with a gap and made in the form of rings, and a screw located in the body, while the screw shaft in the area of the cutting elements is made in the form of a cone , the base of which is located at the end of the lower part of the screw housing, while the cutting elements are interconnected by a hinged parallelogram and are made with the possibility of longitudinal movement along the axis of the screw, as well as at the end of the lower part screw housing in the area of the cutting elements on the axes mounted rollers (RF Patent №2288571, publication date 10.12.2006 g).

The disadvantage of this device is that the feed of the processed material through the cutting elements is carried out by forcing it with a screw, made in the area of the cutting elements in the form of a cone, and also with the help of rollers. In this case, there is no rigid fixation of the material in the cutting zone, which affects the receipt of a significant amount of crumpled material, different in particle size distribution. This disadvantage leads to a decrease in the quality of the crushed material and increase energy costs.

For the prototype, a fruit and root crop chopper was selected, containing a bed, a loading hopper mounted on it, a cylindrical body with reflectors and outlet openings, opposite which removable knife walls are installed, where the processed material is fed to the knife walls using a centrifugal rotor through three guide tubes located under angle of 120 ° relative to each other and performing a rotational movement in a cylindrical body with three outlet openings, opposite which are installed interchangeable knife Tenkai, allowing to obtain slices of varying thickness, the method further comprises a shaker vibrator and the drum type dispenser, the vibrator-side shaker situated hopper; the dispenser is located between the loading hopper and the cylindrical body, while the dispenser has a flap valve in the lower neck, and the outlet openings of the cylindrical body are equipped with plugs (RF Patent No. 152461, publication date 05/27/2015).

The disadvantage of this grinder is the difficulty of adjusting some of the structural and structural parameters of the centrifugal rotor, namely the relative position and size of the outlet openings of the cylindrical body, forming a narrow zone for the crushed product to enter the knife wall. At the same time, adjusting the parameters of the chopper is complicated by the variability of the physico-mechanical characteristics of the processed materials (fruits and root crops). Inadequate adjustment of the parameters reduces the likelihood that the material to be processed from the guide tube will accurately enter the outlet of the cylindrical body towards the knife wall, thereby causing the centrifugal rotor to overload with the remaining material, which significantly reduces the efficiency of the cutting process.

The objective of the utility model is to increase the versatility of the grinder, expand the cutting zone, as well as increase the quality of the crushed material and reduce energy costs.

EFFECT: possibility of carrying out a continuous process of grinding fruit and vegetable raw materials into slices without copious juice generation with reduced energy consumption.

The technical result is achieved by a fruit and root crop chopper containing supports, a cylindrical body, a loading hopper with a vibrator-shaker mounted on it, a drum-type dispenser having a flap valve in the lower neck, a centrifugal rotor with three guide tubes located at an angle of 120 ° relative to each other , an electric motor, while inside the cylindrical case there is a knife case in the form of a truncated sphere formed by arcuate knives, as well as upper and lower disks, fixed interconnected by means of coupling bolts, the knife body is equipped with reflectors, the centrifugal rotor rotates inside the knife body; a protective casing is fixed between the lower disk and the lower part of the cylindrical body, and the container for collecting the crushed product is made singly, located under the discharge openings of the cylindrical body.

In FIG. 1 shows a chopper of fruits and root crops, a general view, and FIG. 2 - chopper of fruits and root crops, section AA.

The device comprises supports 1, a cylindrical body 2, a loading hopper 3 mounted thereon with a vibrator-shaker 4, a drum-type dispenser 5 having an overflow valve 7 in the lower neck 6, a centrifugal rotor 8 with three guide tubes 9 located at an angle of 120 ° relative to each other, an electric motor 10, a knife body 11 in the form of a truncated sphere formed by arched knives 12, as well as the upper 13 and lower 14 disks fixed to each other by means of tie bolts 15, reflectors 16, a protective casing 17, a container for failure a ground product 18 positioned below the outlet opening 19 of the cylindrical body 2.

The device operates as follows.

Before loading the material, the electric motor 10 of the device was launched in order to set the centrifugal rotor 8 to the required rotational speed. The processed material through the loading hopper 3 and the drum-type dispenser 5 entered the centrifugal rotor 8. By transmitting torque to the motor shaft 10, the centrifugal rotor 8 evenly distributed the fruit and vegetable material along the three guide tubes 9. As a result of centrifugal force, the material was removed in the direction of the arcuate knives 12 of the knife body 11 with the linear speed necessary for complete cutting. In this case, the fruit and vegetable material penetrated through the arcuate knives 12, crushed into slices of the required thickness, and then through the reflectors 16 and the discharge hole 19 entered the container for collecting the crushed material 18.

The proposed device allows the process of grinding fruits and root crops without abundant juice and crushing of the crushed materials between the knives with minimal damage to their structure with reduced energy consumption. These factors are ensured by the arched shape of the knives and their radial location relative to the centrifugal rotor, which creates a gap between the knives in the form of a truncated pyramid, i.e. the distance between the knives at the exit is always greater than at the entrance.

The use of arcuate knives radially located relative to the centrifugal rotor forms a wide cutting zone, guarantees the interaction of all processed material released from the guide tubes of the centrifugal rotor with the blades of the knife body at any time, thereby ensuring high efficiency of the cutting process, as well as the possibility of the chopper working without changing settings of operational design parameters.

The device can be implemented in the food industry and agricultural production.

Thus, the claimed chopper of fruits and root crops, containing supports, a cylindrical body, inside of which there is a knife body in the form of a truncated sphere, provides a technical result - the possibility of carrying out a continuous process of grinding fruit and vegetable raw materials into slices without copious juices with reduced energy costs.
