Abstract

Roller flattening device for concentrated feeds for feeding animals in individual and farm households The utility model relates to agriculture, in particular for livestock breeding and can be used in flattening equipment for concentrated feeds for animal feeding. The technical result boils down to simplifying the design, reducing operating costs, including energy, while maintaining the optimal quality of the resulting product. The roller device includes two corrugated rollers 1 mounted on the frame 2 using bearings 3. The drive 4, by means of a V-belt drive 5, rotates the rollers 1, interconnected by helical gears 6 with a large module, which allows the gap between the rollers to be varied to a considerable extent to flatten the feed necessary size. The receiving hopper 7 with the gate 8 provides the optimal flow of concentrated feed for conditioning.

Description

The technical field to which the utility model belongs.

The utility model relates to agriculture, in particular to livestock, and can be used in a device for flattening concentrated feed when feeding animals. State of the art

Known roller mill ZM for grinding grain, containing rollers rotating towards each other at different speeds, and feed rollers guiding the grain into the gap between the rollers, and the rollers are rifled and smooth. The ZM roller mill consists of a bed, two pairs of grinding rollers, two pairs of rollers, a feeding mechanism, drive and control mechanisms, brushes or knives, cleaning rollers, a hydraulic control and signaling machine (see Prince A.E. Myand “Feed preparation machines and units ", M.," Engineering ", 1970).

The disadvantages of this roller mill is:

- design complexity;

- large energy costs of the process, due to the different rotation speeds of the interacting grinding rollers;

- a high degree of grinding of concentrates (into flour);

- unprofitability of application in individual and farm enterprises.

Known roller conditioner, comprising two conditioning rollers mounted for rotation in opposite directions, a pressure roller and a guide visor, moreover, the pressure roller is coated with elastic material and installed to interact with the working surface of one of the conditioner rollers, and the guide visor is fixed in the zone bounded by the surfaces of the rollers and the roller, at a distance from the center of contact of the latter with a flatting roller not exceeding a quarter of the circumference of the roller (see A.S., USSR No. 1041146 class. 02C 4/06).

The disadvantages of this roller conditioner are:

- design complexity;

- insufficient reliability of the adjustable parameters due to uneven wear of the elastic coating of the pressure roller;

- high operating costs associated with cleaning the roller and rollers with high humidity of the crushed material. The closest in technical essence and the achieved positive effect and accepted by the authors for the prototype is a roller mill ЗМ (see pr. A.E Myand "Feed preparation machines and units", M., "Engineering", 1970) the main disadvantages of which are:

- design complexity;

- high degree of grinding;

- large specific energy consumption.

Utility Model Disclosure

The technical result that can be obtained using the proposed utility model is to simplify the design, reduce operating costs, including energy, while obtaining the optimal quality of the resulting product.

The technical result is achieved using a roller device for flattening concentrated feeds when feeding animals, including a frame, grooved rollers and a drive, the width and height of the grooves being equal to the pitch of their distribution over the surface of the rollers, which ensures optimal parameters of the flattening process. Joint drive of corrugated rollers by means of a helical gear transmission allows the rollers to rotate towards each other with equal angular frequency, which prevents the grinding of concentrated feed and the appearance of flour, and a large module of drive gears provides an operational change in the radial clearance between the rollers depending on the required size of the rolled feed. The feed hopper allows you to adjust the feed to

rollers.

Brief Description of the Drawings

In FIG. given a rolling device for flattening concentrated feeds, general view.

The roller device (Fig.) Is a mill, the working bodies of which are two corrugated rollers 1 mounted on the frame 2 using bearings 3. The drive 4 by means of a V-belt drive 5 rotates the rollers 1 connected by helical gears 6 with a large module, which allows to a considerable extent, change the gap between the rollers to flatten the feed of the required size. The receiving hopper 7 with the gate 8 provides the optimal flow of concentrated feed for conditioning.

Roller device operates as follows.

Concentrated feed is manually loaded into the feed hopper?, Which, with the help of a slide 8, is metered to be dosed for conditioning to the grooved rollers 1, the clearance between which is regulated by the movement of the bearings 3 along the frame 2.

The advantage of the proposed device compared to existing technical solutions is the simplification of the design, reducing operating costs, including energy.

Claims (1)

The roller device for flattening concentrated animal feed, including a frame, grooved rollers and a drive, characterized in that the width and height of the grooves are equal to the pitch of their distribution over the surface of the rollers, and the joint drive of the rollers is carried out by means of a helical gear transmission.
