Abstract

FIELD: machine engineering.

SUBSTANCE: grinder includes a body and an electric motor housed therein. On the axis of the electric motor there is a disk mounted in the form of a perforated conical plate, in the inner cavity of which there is a funnel-shaped branch pipe installed coaxially with it. The disk has an impeller with radially placed blades forming sector channels. In the end part the sector channels have a triangular profile. The impeller is located in the internal cavity of the funnel-shaped branch pipe. The impeller is surrounded with a corrugated deck with a gap. The impeller blades have a triangular profile from their end face and are provided with elastic elements with the formation of a "brush" package.

EFFECT: increase intensity of the grinding process.

Description

The invention relates to the mechanization of technological processes of processing and processing of agricultural products.

Known disk chopper containing a receiving hopper, discharge neck, upper and lower disks placed in a housing driven by an electric motor (B.I. Vagin, V.M. Pobedinsky Workshop on mechanization of livestock farms. L., Kolos. 1983 - p. 48, Fig. 11 analogue.).

The disadvantages of this grinder are limited technological and operational capabilities due to the inability to grind wet plant compositions based on soybean and root crops, soybean seeds and vegetables, etc. and simultaneous extraction of nutrients from them (proteins, vitamins, etc.).

A chopper is also known, which contains a housing with an electric motor installed in it, on the shaft of which a disk is fixed in the form of a perforated plate with a large base facing up, and a funnel-shaped nozzle installed coaxially with it in its cavity (RF Patent No. 2127034, IPC A01F 29/00 prototype).

The disadvantage of this grinder is the low reliability due to clogging of the space between the abrasive elements of the grinding apparatus with fibrous particles of vegetable root or vegetable raw materials.

The objective of the present invention is to increase the reliability of the chopper by expanding its technological and operational capabilities in the processing of soya root, soya and vegetable, etc. compositions.

This is achieved by the fact that the perforated disk is equipped with an impeller, the blades of which are arranged radially with the formation of sectoral channels in the end part having a triangular profile, while the impeller is installed in the inner cavity of the funnel-shaped nozzle equipped with a corrugated deck framing with a certain clearance the impeller, the blades of which, with their end faces have a triangular profile and are equipped with elastic elements that together form a brush pack.

The technical result consists in increasing the reliability of the processing of root crops, soya-vegetable and other compositions with a simultaneous increase in the intensity of the extraction process.

In FIG. 1 shows a diagram of a grinder of wet plant products - General view; in FIG. 2 - the same section along aa; in FIG. 3 is a side view A (from the end part of the impeller); in FIG. 4 - a fragment of the figure of the shape of the corrugations on the surface of the deck.

The wet vegetable product shredder includes a housing 1, in which a perforated conical disk 3 in the form of a perforated conical plate is fixed to the shaft of the electric motor 2. An impeller 4 is placed in its inner cavity, coaxially with it, on the shaft of the electric motor 2. The impeller 4 is also placed in the cavity of the funnel-shaped pipe 5 coaxially with it. The impeller 4 contains radially placed blades 6, which, diverging from the axis of the shaft by rays, form sectoral channels (see Fig. 2). From the end of the impeller, these channels have a triangular profile, which during operation with a rotating impeller allows you to "pinch" the particles of the feedstock.

The blades 6 of the impeller 4 from their end part also have a triangular profile. By the area of this triangular profile, elastic elements 7 are placed, which together form a “brush” package.

The impeller 4, through the blades 6 and the elastic elements 7, interacts with the corrugated deck 8, which around the entire circumference, with a gap, frames the impeller 4. The housing 1 is equipped with outlet pipes 9 and 10, as well as a loading funnel 11.

The chopper works as follows. Initially, a composition is fed into the receiving funnel 11, for example, from soaked soybean seeds and ground beet particles simultaneously with water in a ratio, for example, composition: water = 1: 6. Product and water fall on the impeller 4 and under the action of centrifugal force and blades 6 are distributed along the length of sectoral channels.

Under the action of centrifugal force, the particles of the product composition are pressed to the surface of the corrugated deck 8, captured by a "brush" pack of blades 6, pulled by it on the surface of the corrugated deck 7, thereby undergoing the abrasive-crushing action of the deco-brush grinding-extraction apparatus.

The crushed mass of particles is washed abundantly with water and washed off on a dish-shaped perforated disk 3. Under the action of centrifugal force, the resulting suspension is filtered, while the liquid fraction enters the cavity of the housing 1 and then through the nozzle 10 of the crane as intended, and the insoluble pulp residue is discharged through the nozzle 9 and is collected in a container (not shown in FIG. 1).

Thus, the placement of the impeller with blades equipped with elastic elements in the cavity of the funnel-shaped nozzle and aligned with it allows one to process compositions based on grain-fiber products with high reliability, since due to the intensification of the processes the particle size is very small, and the yield of nutrients in water is quantitatively large.
