Description

The utility model relates to means of mechanization of animal husbandry, in particular, to devices for dispensing difficult-flowing materials and can be used in packaging, for example, meat and bone meal and dosing of similar products in other food industries.

A device for dispensing bulk products is known, comprising a loading hopper made with a bulkhead made of a sealed transparent material and a nozzle for supplying bulk products, a housing docked with the hopper, the axis of which has a rotation shaft, a vacuum system, and two parallel tightly adjacent to each other horizontal disk. Moreover, the lower fixed disk having a hole made in it is rigidly fixed at the base of the loading hopper, and the upper disk, in which at least one hole is made, is rigidly connected to the rotation shaft, while all holes in the disks have the same diameters and are equidistant from the axis, the shaft is equipped with a clutch on which a cam is fixed with the possibility of interaction with the limit switch to prevent disc holes from coinciding when the device is stopped. A L-shaped channel is communicated in the housing, communicated at one end with a hole TIFA lower disc and the other end with a filling pipe connected to a receptacle which is formed airtight and provided with a level sensor, a pipe for feeding bulk products sifter communicates with inside of which is maintained at atmospheric pressure. /one/

The disadvantage of the device for dispensing bulk materials is the inability to adjust the metering device depending on the physico-mechanical properties of the material

A dispenser is known that comprises a hopper with a vertical shaft with a drive located inside it and an agitator mounted on the shaft, made in the form of horizontal elements, characterized in that a vertical metering channel is made in the lower part of the hopper, the agitator drive shaft is hollow, the agitator has at least two horizontal elements located on the same side of the shaft, interconnected by a jumper, and an element connected to the jumper and located in the lower part of the hopper at an acute angle to the horizon the main element of the agitator, and, in addition, the dispenser contains a screw located in the metering channel and connected with the screw drive shaft, while the screw drive shaft is located inside the agitator drive shaft, and the screw is removable. / 2 /

The disadvantages of the design of the dispenser are its complexity, the task of preventing arch formation is not always solved.

Known dispenser for bulk materials containing a hopper, a mixing device located inside the hopper, a drive and a collecting unit mounted under the hopper. The drive and the assembly are mounted rotatably around its axis and provided with a volume metering unit located inside the hopper, mounted with reciprocating movement, and equipped with an equalizer fixed to the shaft with the possibility of oscillatory movement in the plane of the upper part of the volume metering unit; the additionally introduced stacker is equipped with a tamper unit, is placed above the collecting unit with the possibility of rotation around its axis, reciprocating movement and impact action in the direction of the material entering the collecting unit, and is equipped with at least one rod facing its end to the collecting unit . / 3 /

The disadvantage of the doser of bulk materials is the complexity of the design, as well as caking of the material.

The present invention solves the problem of preventing arching and caking of the material.

The problem is solved in that the dosing device for powdered materials, consisting of a loading hopper and the screw placed in it, as well as a measuring device, a spring-loaded stop and a reducer, the hopper is hinged and, depending on the physicomechanical properties of the product, the angle of inclination of the screw is adjustable by turning the hopper, the translational movement of the graduated cylinder is carried out from the screw drive, due to the gearbox, while the gap between the bottom of the hopper and the stirring-feeding screw is made with possibly Tew adjustment considering the material properties, and in addition has additional auger blades located between its windings, for mixing of material, and the inlet window to the metering device is adjustable, and the rate of dispensing is adjustable relative movement of the piston and the measuring cylinder.

This device is illustrated by drawings, in which Fig. 1 shows a diagram of a metering device for powder materials, Fig. 2 is a diagram of a device for adjusting the gap between the screw and the bottom of the hopper; figure 3 shows a diagram of the adjustment of the relative position of the measuring device; figure 4 - strip device for adjusting the gap between the auger and the bottom of the hopper.

The metering device consists of a loading hopper 1 located in it auger 2, measuring device 3, a spring-loaded stop 4, as well as a gear 5.

A dosing device for powder materials works as follows. The dosed material enters the hopper 1, from where the screw 2 is transported to the measuring device 3, made in the form of a cylinder. The auger is angled. The auger has a conveying function as well as a mixing function. Measuring cylinder 3 performs a reciprocating movement from the loading hole to the discharge. At the discharge opening there is a spring-loaded stop 4, which contributes to the complete unloading of the graduated cylinder. The drive of the graduated cylinder is carried out through the gearbox 5 from the shaft of the screw 6.

The accuracy of the dosage depends on the uniformity of the mixture, which can be achieved as a result of mixing, that is, the involvement of particles of the material in a complex movement. The angle of the screw depends on the angle of repose, the feed of the dosed material on the one hand, the quality and energy intensity of the operation on the other.
