Abstract

FIELD: feed production.

SUBSTANCE: feed mixer includes a housing, at opposite ends of which a loading hopper and an unloading window are installed. A shaft is installed in the inner cavity of the housing, the geometric axis of rotation of which coincides with the longitudinal axis of symmetry of the housing. A mixer is installed at one end of the shaft, and a screw with a screw winding is installed at the other. The mixer and the screw are made separately and connected to each other via a detachable connection. The body is divided into receiving and working chambers. The screw is located in the receiving chamber, which is installed under the loading hopper. Moreover, the mixer is made in the form of a screw with perforated winding and is located in the working chamber, which is installed above the unloading window. The working chamber and the receiving chamber at the junction of the screw with the mixer at the ends have flanges to ensure the bolted connection of these body chambers.

EFFECT: device reduces the energy intensity of the mixing process, improves the quality of mixing and expands functionality.

Description

The invention relates to the field of agriculture, namely to devices for the preparation of feed on livestock farms, complexes and poultry farms.

A known feed mixer for preparing mixed feed includes a casing, at opposite ends of which a loading hopper and an unloading window are installed, a shaft is installed in the inner cavity of the casing, the geometric axis of rotation of which coincides with the longitudinal axis of symmetry of the casing, an auger mounted at one end of the shaft, at the other end a shaft mounted mixer, made in the form of a screw with a helical winding, with elements fixed on it and bent along a helical line, on the other - a screw with a helical winding. (RU 202399 U1, class A23N 17/00, В02С 19/00, 2021).

The known feed mixer contains a casing, at opposite ends of which a loading hopper and an unloading window are installed. A shaft is installed in the inner cavity of the casing, the geometric axis of rotation of which coincides with the longitudinal axis of symmetry of the casing. A mixer is installed at one end of the shaft, and a screw is installed at the other. The stirrer is made in the form of disks bent along a helical line with the disks placed on the shaft so that the cutting edges of adjacent disks are placed in the same vertical plane and secured to hubs mounted on a hexagonal shaft. The invention provides an increase in the productivity of the feed mixer (RU 2752931 C1 - prototype).

The disadvantages of this device are the high energy intensity of the working process, poor quality of grinding the grain mass and the inability to mix feed of different fractions.

The technical result is to reduce the energy intensity of the mixing process, improve the quality of mixing and expand functionality.

The technical result is achieved by the fact that in a feed mixer, which includes a housing at opposite ends of which a loading hopper and an unloading window are installed, a shaft is installed in the internal cavity of the housing, the geometric axis of rotation of which coincides with the longitudinal axis of symmetry of the housing, a mixer is installed at one end of the shaft, the other is a screw with a screw winding; according to the invention, the mixer and the screw are made separately and connected to each other by means of a detachable connection, and the body is divided into a receiving and working chamber, the screw is located in the receiving chamber, which is installed under the loading hopper, and the mixer is made in the form of a screw with perforated winding is located in the working chamber, which is installed above the unloading window, while the working and receiving chambers at the junction of the screw with the mixer at the ends have flanges to ensure a bolted connection of these housing chambers.

The novelty of the proposed technical solution lies in the fact that a comparative analysis with the prototype shows that the proposed feed mixer differs from the prototype:

1. Making the mixer and auger separately and connecting them to each other via a detachable connection and dividing the body into a receiving and working chamber makes it possible to change the mixer for mixing feed of different fractions.

2. Perforated screw winding located on the shaft of the working chamber allows for improved mixing.

The identified features of the technical solution of the claimed feed mixer allow us to conclude that the technical solution meets the “inventive step” criterion.

The invention is illustrated by a drawing, where Fig. 1 is a schematic representation of the general view of the feed mixer; Fig. 2 shows a diagram of the mixer in 3D format

The feed mixer includes a housing 1, a loading hopper 2 and an unloading window 3; a shaft 4 is installed in the internal cavity of the housing, made in the form of a pipe. At one end of the shaft 4 there is a mixer made of an auger with a perforated winding 5, at the other - an auger 6 with a screw winding Housing 1 is divided into receiving and working chambers 7 and 8, respectively. The mixer and screw 6 located on the shaft 4 are made separately and are connected to each other by means of a detachable connection in the form of a pin 9. The screw 6 is located in the receiving chamber 7 under the loading hopper 2, and the mixer is in the working chamber 8. The working chamber 7 and the receiving chamber 8 are in At the junction of the screw 6 with the mixer, there are flanges 10 at the ends to provide bolted connections 11 of these housing chambers. Shaft 4 is supported on the side of the unloading window by a radial bearing 12, and on the side of the hopper by a tapered bearing 13.

This design of the mixer makes it possible to replace the mixer with other parameters, depending on the type of feed. The feed mixer works as follows.

The feed is fed into the loading hopper 2, from there it enters the receiving chamber 7, in which the auger 6 is located; when it rotates, the feed is initially mixed and dosed. Next, the feed enters the working chamber 8, where, by pouring through the perforated winding 5 of the mixer, a turbulent flow is created, mixing the feed and unloading the finished mixture through the unloading window 3.

The proposed design compared to the prototype and other known technical solutions has the following advantages:

- reducing the energy intensity of the process; - improving the quality of feed mixing by creating a turbulent movement of the feed flow in the mixer.
