DISPENSER-MIXER Russian patent published in 2019 - IPC G01F11/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to means of mechanization of livestock sector, in particular, to devices for mixing dosage portions of bulk materials from grain crops. Dispenser mixer comprises hopper, installed vertically and divided into sectors with shutters, one of which is rigidly fixed, and others are installed with possibility of angular movement relative to fixed shutter and fixation in required position by screws, at the lower end of the hopper a telescopically installed collar, a disc with a diameter larger than the diameter of the collar installed below it and rigidly fixed relative to the hopper, a drive shaft, scrapers interacting with the disc and rigidly connected to the drive shaft, a main funnel, the diameter of which is greater than the diameter of the disc placed under the latter, having openings on the mouth of the socket, and a diffuser with an independent drive under the neck, an additional funnel with a neck, rigidly connected to the main funnel and placed under the latter, in the mouth of the additional funnel there are installed spiral guides with windings with opposite directions, which are directed relative to the scatterer rotation direction. According to the invention, the collar has a slit-shaped end of the saw shape divided in accordance with the hopper sectors, the height of the teeth and the distance between which corresponds to average geometrical dimensions of grains of grain crops, taking into account the flotation ability of a certain amount of grain in accordance with the ratio of grain doses. Collar is installed with the possibility of movement in the vertical direction and its fixation, than the clearance between the disc and the saw-shaped split-shaped split in compliance with the hopper sectors is regulated simultaneously for each sector separately, thereby higher accuracy of dosing the required ratio of feed components.

EFFECT: improved quality of the mixture by higher accuracy of dispensing components of the grain mixture.
