Moreover, according to a utility model, the agitator may comprise at least two blades placed on the shaft.

Moreover, according to a utility model, the nozzle can be corrugated.

Moreover, according to a utility model, the dispenser may comprise a hopper communicating with the second chamber and located above the last one.

Moreover, according to a utility model, the auger can be made tape.

Moreover, according to a utility model, the screw can be made screw.

Moreover, according to a utility model, the first shutter shutter may be provided with a pneumatic cylinder.

Moreover, according to a utility model, the first shutter damper can be equipped with an electric drive.

Moreover, according to the utility model, the second shutter shutter may be provided with a pneumatic cylinder.

Moreover, according to the utility model, the second shutter damper can be equipped with an electric drive.

The present utility model is illustrated by drawings (Figs. 1-3), an example of a dispenser on which, however, is not the only possible, but clearly demonstrates the possibility of achieving the claimed technical result.

According to a utility model, the dispenser comprises a first chamber 1 with a screw 2 installed therein. The screw 2 is rotatable around the first axis 3 from the first drive 4 (Fig. 1, 2). The screw 2 can be made tape or screw. At the output of the first chamber 1, there is a first shut-off valve 5 and a container 6. The valve 5 can have a drive, which can be used as a pneumatic cylinder or an electric drive. In FIG. 1-3, pneumatic cylinder 7 is shown as a drive. Capacity 6 is provided with at least one strain gauge sensor 8 (Figs. 1 and 3). In FIG. 1 shows the design of a dispenser with one strain gauge sensor. In FIG. 3 shows a different number of sensors 8 and possible options for their location.

The dispenser also contains a second chamber 9 connected to the first chamber 1 and mounted above it, having a U-shape in cross section (Fig. 2). An axial shaft 10 is located in the chamber 9 with the agitator 11 mounted on it. The agitator 11 is rotatable from the second drive 12, the first axis 3 and the axial shaft 10 being parallel (Fig. 1, 2). At least two blades 13 can be placed on the axial shaft 10 of the agitator 11. The output tank 6 is provided with a second shutter shutter 14. The shutter 14 can be equipped with a drive, which can be a pneumatic cylinder or an electric drive. In FIG. 1, the pneumatic cylinder 15 is shown as a drive. The first chamber 1 and the container 6 are connected by a nozzle 16. The nozzle 16 is rigidly connected to the first chamber 1 by one end and connected to the container 6 by a nozzle 17 made of elastic material (Fig. 1). The nozzle 17 can be made corrugated .. The dispenser is mounted on vibration mounts 18. The dispenser can also be equipped with a hopper 18, which is used to receive the dosed material, made communicating with the second chamber 9 and located above it. In the case when the hopper 18 is not dosed material is loaded directly into the second chamber 9.

The dispenser works as follows.

The dosed material is loaded into the hopper 18, poured below and falls on the agitator 11 of the U-shaped chamber 9, which mixes the material, prevents arching and sticking of the material to the walls of the chamber 9. The implementation of the chamber 9 of the U-shaped shape avoids the formation of stagnant zones and contribute to continuous uniform flow of material into the chamber 1 for dispensing and transportation. Further, the material with the help of a screw 2 enters the tank 6. The execution of the first axis 3 and the shaft 10 parallel as well as other structural elements of the dispenser, increases the accuracy of dosing. The pipe 16 and the elastic nozzle 17 of the pipe 16 avoid undesirable dusting of the dosed material, introducing errors in its dosage. When filling the tank 6 with the required mass, the first shutter valve 5 closes and the second shutter valve 14 opens, and the material enters the container intended for it.
