Abstract

FIELD: agriculture.

SUBSTANCE: device for mixing loose fodders and additives consists of a multi-section hopper for loose fodders and additives with a multicomponent dispenser having removable blade drums in the form of hubs with flat radial blades in the quantity of 6…12 pcs. and discharge openings in the form of slots, closed by adjusting flaps, the blade drums being fixed on a common shaft in three to seven sections of the hopper. Under the multicomponent dispenser, there is a premixing chamber in the form of a trapezoidal prism, under which there is a main mixing chamber, which is represented by a cylinder, on the axis of which two successive working active mixing bodies are fixed to a drive shaft. The first working body is located in the loading area and is represented by a screw, and the second working body is intended for mixing and unloading and is represented by a single-thread spiral conveyor made of a rod round in section, with the diameter of 5…12 mm, also fixed to the shaft directly behind the screw; after the spiral conveyor, a discharge tray is arranged.

EFFECT: obtaining a dry mixture depending on the formulation determined, high quality of mixing fodder components, simplicity of structure making, low energy consumption for obtaining the mixture.

Description

The invention relates to agriculture, in particular to devices for the preparation of feed on livestock farms and complexes.

A device for mixing dry feed and making additives (A.S. No. 2422054, IPC A23N 17/00, BI No. 18 06/27/2011). It consists of a mixing chamber, a loading hatch, a mixing screw enclosed in a casing, mixing blades, demolition blades, an unloading screw, a conveyor-mixer, made in the form of a spiral-blade conveyor, necks for loading dry feed and additives.

The disadvantages of this device for mixing dry feed and making additives include the presence of a large number of drives for metering devices. The presence of a spiral in the loading zone of the components can lead to an uneven entry of the components into the mixture and a violation of the formulation of the mixture in a specific volume.

A device for adding additives to dry feed (a.s. No. 2547467, IPC A23N 17/00, BI No. 10 04/10/2015), consisting of a mixing chamber, over which there is a preliminary mixing chamber with a loading hatch and 4-6 bins dispensers, and under the mixing chamber there is an inclined screw conveyor with a mixing screw.

A vertical mixing auger is installed in the mixing chamber, the upper part of which is single-entry, and the lower part is dual-input. Also in the upper and middle part of the screw there are L-shaped blades of circular cross section. The mixing chamber of the preliminary mixing is made of rectangular cross-section, inside of which flat chevron-shaped blinds are attached.

Dosing hoppers have paddle drums having from 8 to 30 flat radial blades, and a casing with rectangular slit-like discharge openings covered by interchangeable overlays.

The continuous mixer is made in the form of a spiral-vane conveyor. The working body is a mixing auger, which has three structural and technological zones (receiving components, transportation and unloading). In the reception area of the components there is a single-feed auger with an increasing pitch of the spiral. In the transportation zone there is a bar spiral with flat blades. The third zone has a bar spiral, with a baffle plate and radial flat blades.

The disadvantages of the device for adding additives to dry feed include the fact that the presence of a batch mixer as part of this device significantly increases the energy consumption of mixture formation.

Of the closest in technical essence is a device for mixing dry feed and liquid additives (AS No. 2336690, IPC A01K 5/00, BI No. 30 10/27/2008). The device consists of a hopper for dry feed, in which a discharge screw is installed, a humidification (mixing) chamber, a dispenser for liquid feed, and the discharge screw of the hopper for dry feed is made in the form of a spiral of circular cross section, which is double-entry in the discharge zone and the discharge zone is closed mesh with round holes with a diameter of 8-14 mm. An additional mixing chamber is also installed, inside of which a spiral auger is placed, and the discharge opening is blocked by an adjustment flap.

At the same time, a mixing chamber is additionally installed under the humidification chamber, inside of which there is a spiral auger, and the discharge opening is blocked by an adjustment flap.

The disadvantages of this device for mixing dry feed and liquid additives are its specialization under the introduction of liquid additives and the inability to make dry additives. The presence of an adjustment flap at the discharge opening can lead to filling of the mixing chamber with material and failure of the spiral screw drive.

The claimed invention is aimed at eliminating the above-mentioned disadvantages of the known device. From its use, the following result can be obtained: obtaining a dry mixture depending on a given recipe, high quality mixing of feed components, ease of manufacture of the structure, low energy consumption of the mixture.

Graphic materials.

In FIG. 1 shows a device for mixing bulk feed and additives.

The specified technical effect is achieved through the use of a device for mixing bulk feed and additives. A device for mixing bulk feed and additives consists of a multi-section hopper 1 bulk feed and additives with a multi-component dispenser 2, in which three to seven sections on a common shaft 3 are fixed removable vane drums 4 in the form of hubs with flat radial blades 5 in the amount of 6 ... 12 PC. and discharge holes in the form of slots, overlapped by the adjustment flaps 6, while under the multicomponent batcher 2 there is a pre-mixing chamber 7 in the form of a trapezoidal prism, under which there is a main mixing chamber 8, which is a cylinder along the axis of which two are mounted in series on the drive shaft 9 located working body of the active mixing, and the first working body is located in the loading zone and is a screw 10, and the second working body, designed to be mixed and unloading and which is a one-way spiral conveyor 11, made of a round bar with a diameter of 5 ... 12 mm, also mounted on the shaft 9 directly behind the screw 10, after the spiral conveyor 11, the unloading tray 12 is located.

The operation of the device for mixing bulk feed and additives is as follows: the loaded bulk feed and additives in the sections of the hopper 1 are captured in a circular motion by flat radial blades 5 of the blade drums 4, while the discharge of components occurs through the discharge openings. The supply of components is regulated by the position of the adjusting dampers 6. The flows of components through the pre-mixing chamber 7 enter the main mixing chamber 8, while the screw 10 mixes and directs the mixture into the working area of the spiral conveyor 11, which captures the mixture, further mixes and moves to the discharge chute 12.
