Abstract

FIELD: agriculture.

SUBSTANCE: device for grinding roots and tubers consists of two stages of grinding. The first stage consists of two horizontal flat removable knives, crossbars and stops. The knives are mounted on a vertical shaft at an angle to the rotation plane. The stops are fixed on the inner surface of the cylinder chamber storage. The second stage includes flat knives and a roller support. The knives are installed on the ring. The vertical shafts of the first and second stages are connected through a bearing support. The shafts can be independently rotated relative to each other.

EFFECT: operational reliability and improved grinding quality.

Description

The invention relates to agriculture, in particular to devices intended for the preparation of root crops for feeding.

A device for washing and grinding root crops (see as.with. No. 171212 USSR, IPC A01F 29/00), containing a screw washing and removable knife frame, located in the loading window of the screw washing, the latter is made in the form of a body, obliquely mounted on the frame in which the screw is located.

Known feed chopper (see AS No. 1547775 A1 USSR, IPC A01F 29/00) containing a screw with a blade mounted at its end, a housing with loading and unloading windows and an arcuate knife grate, located in the unloading window of the housing under the blade.

As a prototype, a juicer feed chopper (see AS No. 2288571 of the Russian Federation, IPC A01F 29/00) was adopted, comprising a body, the wall of which is made of cutting elements installed in the lower part of the body, located between each other with a gap and made in the form rings, and a screw located in the housing, 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.

The disadvantages of such devices for grinding are the insufficient quality of grinding and low operational reliability.

The technical challenge is to improve the quality of grinding and operational reliability.

In FIG. 1 shows a device for grinding root tubers, general view; in FIG. 2 is a sectional view of FIG. one.

To solve this technical problem, a device is proposed that consists of two stages of grinding - the first stage of the disk type and the second stage - with flat knives mounted on the ring, and roller support.

The first grinding stage consists of two horizontal flat removable knives 1 mounted on a vertical shaft 2 at an angle to the plane of rotation, contradictions 3 and stops 4, mounted on the inner surface of the drive of the cylindrical chamber 5.

The second grinding stage consists of a cylindrical chamber 6, along the perimeter of which a block of vertical plate knives is installed 7. A shaft 8 passes through the center of the chamber, on which the impeller 9, cone 10 and carrier 11 are mounted. Rollers 12 are mounted on carrier 11, which rotate freely in the bearing units on the axles 13.

Vertical shafts of the first and second stages are interconnected through a bearing support and have the ability to independently rotate relative to each other - the drive of the first grinding stage is carried out by an electric motor 14 with an adjustable speed, and the drive of the second stage includes a gear motor 15 and a chain gear 16.

The device operates as follows.

Pre-cleaned root crops in the sink through the loading neck 17 enter the cylindrical chamber 5 of the first stage, where, under the action of the knives 1, they are pre-cut to sizes that ensure their guaranteed passage between the vertical knives of the removable block. Then the root crops fall on the inclined cone of the grinding device, where, under the action of gravity and centrifugal forces created by the rotation of the cone 10, they are pressed against the knife block 7, captured by rollers 12 and forced through the knife grate. The finished product under the action of the impeller 9 through the neck 18 is discharged from the grinding device.

The degree of grinding of root crops is regulated by the installation of a removable block of vertical plate knives 7 with different distances between them.

Such a scheme of the device allows you to get slices that meet zootechnical requirements, which as a result leads to an increase in the quality of grinding. Moreover, the first stage of grinding can be used only when grinding large root crops, for example, such as fodder or sugar beets, which reduces the specific energy costs. In addition, the use of the first stage allows you to reduce the impact of large root crops on the block vertical plate knives, thereby increasing its performance.

Claims (2)

1. A device for grinding root crops containing two stages of grinding - the first stage of the disk type and the second stage with flat knives mounted on the ring, and roller support, characterized in that the first grinding stage consists of two horizontal flat removable knives mounted on a vertical shaft at an angle to the plane of rotation, contradictions and stops fixed on the inner surface of the drive of the cylindrical chamber, and the vertical shaft of the first stage has the possibility of independent rotation contact relative to the shaft of the second grinding stage. 2. A device for grinding root crops according to claim 1, characterized in that in order to simplify the operation of replacing the vertical blade knives during sharpening, the block is removable.
