Description

 The invention relates to equipment for the manufacture of minced meat and can be used, in particular, for the manufacture of minced meat.

 A device for the manufacture of minced meat containing a working chamber, a conveying device, a drive, a cutting set consisting of rotating knives and fixed lattices [1].

The disadvantage of this device is the winding of the hymen on the knives due to the different linear speeds of the feathers of the knife (from v = v _max to v = 0).

 It is also known a device for the manufacture of minced meat, containing a working chamber, a conveying device, a drive, a cutting pair, consisting of two movable flat lattices with the same holes, making linear movements in antiphase relative to each other. The gratings are connected, as the authors indicate, for example, with an electromagnetic oscillating drive. According to the authors, the movement of the gratings creates a vibrating field around the cutting pair, which significantly reduces the friction force when feeding raw materials into the holes of the grating. At the exit from the openings of the first lattice, the particles of raw materials are cut off by the openings of the second lattice [2] (prototype).

 The disadvantage of this device is the complexity of the drive and the working chamber. The motion of flat gratings moving in antiphase can be carried out either using an electromagnetic oscillating drive, or using a drive containing complex kinematic nodes such as a crankshaft or cams with a return spring mechanism. On the other hand, linear oscillatory movements of the gratings imply the obligatory presence in the working chamber of the sealing units of the sections of the connection of the gratings with the drive elements. The absence of sealing nodes is possible only if the gratings are driven through a continuous wall of the working chamber, which will mean an even greater degree of complexity of the electromagnetic oscillating drive.

 An object of the invention is to simplify the design of the drive.

 The technical problem is achieved in that in a device for the production of minced meat containing a working chamber, a drive, movable grills, a transporting unit, according to the claimed invention, the working chamber is made in the form of a hollow stationary cylinder, the side wall of which is provided with a perforated segment and a window through which meshing occurs gears of the drive with splines of the hollow rotor coaxially mounted inside the fixed cylinder with the possibility of rotation and equipped with longitudinal ribs and rings th perforations, wherein the conveying unit is made in the form of longitudinal ribs and the screw rotor, is fixedly mounted within the rotor.

The inventive device has the following distinctive features in comparison with the prototype:
- the working chamber is made in the form of a hollow stationary cylinder, the side wall of which is equipped with a window with a perforated segment - this allows one of the gratings to be made in the form of a fixed cylindrical segment with the possibility of its tight pressing against the second movable grating;
- the working chamber is made in the form of a hollow stationary cylinder, the side wall of which is provided with a window through which the gear of the drive gears with the slots of the hollow rotor, which allows the use of simple gearing to bring the second movable lattice into rotation;
- inside the working chamber, made in the form of a hollow stationary cylinder, a hollow rotor is coaxially mounted for rotation and equipped with annular perforation, which allows the movable grate to be made in the form of a rotating perforated section, thereby eliminating the need to seal the connection of such a grate with drive elements;
- inside the working chamber, made in the form of a hollow stationary cylinder, a hollow rotor coaxially mounted for rotation and equipped with longitudinal ribs, as well as a fixed screw, which allows you to combine the transport of raw materials and cutting and simplify the drive device.

In FIG. 1 shows a vertical section of the device, figure 2 is a view of the remote element A in figure 1; figure 3 is a section bB in figure 2; figure 4 is a view of the remote element B in figure 1; figure 5 is a view of section aa in figure 1; figure 6 is a view of the remote element In figure 1
The device comprises a working chamber in the form of a hollow stationary cylinder 1 with a hollow rotor 2 coaxially mounted inside it and having longitudinal ribs 3. The ribs are made on the inner surface of the hollow rotor 2. A hopper 5 is mounted on the lid 4 fixed in the upper part of the hollow stationary cylinder 1 and a sleeve 6 with a square socket 7 for mounting therein the motionless upper end of the axis of the screw 8. The screw 8 forms a transporting unit with longitudinal ribs 3. An unloading chute 9, a perforated segment 10 and a drive 11 (with a variator) with a gear wheel 12 and an intermediate gear 13 that rotates on the axis 14 and rotates the hollow rotor 2 due to engagement with the teeth 15 are installed on the side wall of the hollow stationary cylinder 1. The engagement itself occurs through the window 16 in the wall of the hollow stationary cylinder. In the lower part of the hollow stationary cylinder 1 there is also a window in which a perforated segment 10 is installed. A window with a perforated segment 10 in the wall of the hollow stationary cylinder 1 and the annular perforation 17 made in the lower part of the hollow rotor 2 are movable cutting elements.

 The device operates as follows.

 The raw material supplied to the grinding is loaded through the hopper 5 and enters the upper part of the hollow stationary cylinder 1. Here, the raw material under the influence of its own weight and rotating ribs 3 of the hollow rotor 2 is mixed in a spiral formed by the turns of the fixed screw 8 into the lower part of the hollow fixed cylinder 1 and goes to the cutting pair formed by annular perforation in the lower part of the hollow rotor 2, and a perforated segment 10 mounted on the side surface of the hollow stationary cylinder 1. Rotation of the screw 8 is excluded for even the installation of the ends of its axis in square sockets 7, made, for example, inside the sleeve 6. Pushing through the annular perforation of the hollow rotor 2 in the area of contact with the surface of the perforated segment 10, the particles of raw materials are cut off by the edges of the holes. The edges of the holes of the annular perforation move towards the fixed edges of the holes of the perforated segment. The perforated segment 10 in the working position is tightly pressed against the outer surface of the hollow rotor 2 by known devices, for example, spring-screw. Raw materials, crushed annular perforation — a perforated segment — are discharged from the device through the tray 9. The hollow rotor 2 receives rotation from the drive 11 with the variator through the gear wheel 12 and the intermediate gear 13, which is engaged with the slots 15 in the upper part of the hollow rotor 2.

 The degree of grinding products is regulated by a smooth change in the frequency of rotation of the hollow rotor 2 through the use of a variator in the drive circuit 11.

 To wash the device, the cover 4 is removed, the screw 8 and the hollow rotor 2 are removed.

Compared with known devices for the production of minced meat, the claimed invention is different:
- exception from the cutting set of cutting knives, which allows to reduce the cost of production of the structure;
- a simpler diagram of the supply of raw materials to the cutting pair and a simpler diagram of the drive itself through the use of a fixed screw and slots on the surface of a rotating lattice (hollow rotor) - this reduces the cost of manufacturing the device.
