A disadvantage of the known device is its large size and complexity.

A known unit for mixing bulk materials containing dispensers, a mixing device in the form of a blade shaft located in the housing, a conveyor belt (RF patent for the invention No. 2132723, publ. 10.07.1999).

The disadvantages of this device are the friction of the blades on the tape, leading to rapid wear of the tape, the difficulty of ensuring complete selection of material from the tape, the adhesion of the material prone to adhesion on the inner surface of the housing.

A known unit for mixing bulk materials (RF patent for the invention No. 2242272, publ. 12/20/2004) containing dispensers, a housing located in the housing shaft with a disk and blades mounted on it, which have windows and a fencing element attached to them. The unit has conical surfaces, it also contains drums with parallel axes, on the surface of one of which there are radial elastic elements.

The disadvantages of this device include the complexity of the design and the relatively low quality of mixing.

A known unit for mixing bulk materials (RF patent for the invention No. 2326025, publ. 10.06.2008) containing dispensers, an unloading device, a housing located in the housing, a bump and a shaft with a disk and blades mounted on it and a drive. Moreover, a conical element is attached to the disk, and elastic elements are installed on the lateral surfaces of the blades, and the chipper has a curved shape.

A disadvantage of the known unit is the complexity of the technology for mixing bulk materials, low efficiency and relatively high energy consumption.

A known installation for producing mixtures (certificate of the Russian Federation for utility model No. 23393, publ. 06/20/2002) containing a loading hopper, a mixing device and a storage hopper mixture. As a mixing device, a vertical-screw batch mixer is used, over which a loading hopper is placed. The installation is also equipped with two conveyors, a module for filling the resulting mixture and an elevator, with the mixture storage hopper located above the packaging module, one conveyor installed behind the mixer, the second behind the packaging module, and the elevator is located between the first conveyor and the packaging module.

A disadvantage of the known design is the complexity of the design of the device.

A known batch mixer (USSR author's certificate No. 886957, published 07.12.1981) containing a horizontal stationary drum with rotating blades, loading and unloading hatches, air nozzles with a funnel of an electronic suction connected to a feed hopper having a discharge hole in the lower part .

The disadvantage of this device is its high height, which does not allow its use in small buildings in small-scale production.

The closest in technical essence and the achieved positive effect to the claimed device for mixing and packing bulk materials - the prototype - is a weighing batcher for packing bulk substances in bags (RF patent for utility model No. 77678, publ. 27.10.2008) containing a storage hopper with a tight gate valve at the inlet and outlet of it. At the output, the valve is installed in the pipe, on which a sleeve made of corrugated rubber hose is put on, and the other end of the corrugated rubber hose is dressed in the output pipe, which contains a strain gauge for determining its angle of inclination. In addition, the storage hopper contains an air duct for supplying compressed air and a source of compressed air.

The known installation is structurally very complex and can be used only for large volumes of work.

Utility Model Implementation

A device for mixing and packing bulk materials contains: a mixing hopper 1 of gravitational action with an electric motor 2 mounted on a supporting frame 3, a casing 4, a cover 5, a conical hopper 6, a feeding screw 7 with an electric motor 8, a sieve with a funnel 9, a vibrator 10, a counterweight 11, an electrical panel 12. The upper part of the mixing hopper 1 is provided with a casing 4 with a cover 5, and a cone-shaped hopper 6 is installed in the lower part. A feeding screw 7 is located in the lower part of the conical hopper 6. A sieve with a funnel 9 is fixed to the supporting frame 3 and a vibrator 10, a counterweight 11 is connected to them. An electrical panel 12 is also mounted on the supporting frame 3.

A device for mixing and packing bulk materials works as follows.

Dry mixes are served at the place of work, for example: gypsum, sand, fillers and other components. Open the cover 5 on the casing 4, rotate the sieve with the funnel 9, using a counterweight 11, which is designed to reduce the effort when lifting the sieve with the funnel 9, the components of the dry mixes are covered.

The installation is switched on using an electrical panel 12 mounted on a supporting frame 3. At the same time, thanks to the vibrator 10, the components are sieved and fed into the mixing hopper 1 of gravitational action. At the same time, the electric motor 2 is turned on and the components of the dry mixture are mixed. After that, the finished mixture is poured into a cone-shaped hopper 6, and then by means of a feeding screw 7 operating from an electric motor 8, the dry mixture is packed in a paper bag with a filling valve.

Thus, as a result of the implementation of the claimed utility model, simplification of the design, increase in reliability and productivity of the device for mixing and packing bulk materials are achieved.

A comparative analysis of the claimed utility model showed that the set of essential features of the claimed device is not known from the prior art and therefore corresponds to the patentability condition “Novelty”.

The above information confirms the possibility of using the claimed device for mixing and packaging materials, which can be used in the construction, mining, chemical and other industries related to the processing of bulk materials, and therefore meets the patentability condition "Industrial applicability".
