Abstract

FIELD: construction.

SUBSTANCE: invention relates to the construction industry, in particular, to the production of cement wood. The device comprises a cylindrical body, a driving shaft and an electric drive, and an accessory for mixing in the form of blades. The body is installed on a hinged support. At both sides from the hinged support there are dampers installed. Inside the body there is a cylindrical reducer installed. On output shafts of the reducer there are mixing blades mounted as capable of counterrotation in pairs at each side. The reducer is rigidly fixed at the bottom of a load trolley and is connected by means of a chain gear with an input shaft of a conical reducer and with an electric engine. On the output shaft of the conical reducer there are driving wheels of the load trolley mounted.

EFFECT: improved quality of mixing of wood particles with a binder, simplified design of a device.

Description

The invention relates to the construction industry, in particular to the production of building material - wood concrete.

Known technical solutions (copyright certificates 1175700, 1283103, 1472262, 1479270, class B27N 1/02), consisting of a cylindrical body with loading and unloading windows, devices for mixing and drive.

A known mixer is predominantly for producing a mixture of a filler and a binder, comprising a housing with a shaft horizontally mounted with a shaft equipped with mixing blades and arranged along the components in series in front of the mixing blades, which are loading for introducing the filler and the connecting pipe, the last of which has at least one nozzle with a coaxial needle, and also a discharge pipe located along the components behind the mixing blades (copyright certificate No. 498182, IPC B27N 1/02, 1976).

The disadvantage of these designs is the insufficient quality of mixing wood particles with a binder.

A device for mixing wood particles with a binder (patent No. 2154572, class B27N 1/02) is known, which, by its technical nature and the achieved effect, is a prototype and consists of a housing inside which mixing blades, a loading nozzle, and also an unloading nozzle located along the progress of the components behind the mixing blades.

The disadvantage of the prototype is the complexity of the design.

The technical result is to simplify the design and expand technological capabilities.

The technical result is achieved by the fact that the device comprises a housing with a hinged support mounted below, on both sides of which dampers are installed, and inside it is a cylindrical gearbox, on the output shafts of which mixing blades are mounted in pairs on each side with the possibility of counter-rotation, the gearbox itself is rigidly fixed from below of a freight trolley and is connected via a chain drive to the input shaft of a bevel gear on one side and an electric motor on the other, while on the output shaft of a bevel gear drive wheels mounted trolley.

The invention is illustrated by drawings, where in Fig.1 shows a side view; figure 2 presents a front view.

A device for mixing wood particles with a binder contains a cylindrical body 1, a drive shaft and an electric drive, as well as devices for mixing in the form of blades. The casing contains a hinge support 2 mounted below, on both sides of which dampers 3 are mounted, and inside it there is a cylindrical gear 4, on the output shafts 5 of which, mixing blades 6 are mounted in pairs with each other with the possibility of counter-rotation, the gear 4 is rigidly fixed at the bottom of the cargo trolley 7 and is connected via a chain gear 8 with the input shaft 9 of the bevel gear 10 on one side and an electric motor 11 on the other, while the drive wheels 13 of the truck are mounted on the output shaft 12 of the bevel gear trolley 7, which is mounted on rails 14, with limit switches 15.

The mixer operates as follows: The torque from the electric motor 11 is transmitted to the input shaft 9 of the gearbox 10, to the chain gear 8, from which to the cylindrical gearbox 4 and to its output shafts 5, and therefore to the blades 6. Since the blades 6 are placed on the one hand on different shafts, due to this, the opposite rotation is achieved relative to each other. Due to the fact that there is a gap between the profiles of opposing blades - this ensures high-quality mixing.

In addition, the mixing of the mixture is carried out by moving the cargo trolley 7 relative to the housing 1 of the device. In this case, due to the displacement of the center of gravity of the trolley in one or the other direction, the body tilts and the mixed mass is displaced, and this also contributes to the quality of mixing. The change in the direction of movement of the cargo trolley occurs due to limit switches 15 installed along the edges of the guides 14 of the trolley.

The housing 1 is moved to the extreme position, the mixed mass is unloaded, loaded again, and the work cycle is repeated.

Using the proposed device can improve the quality of mixing wood particles with a binder.
