MIXER FOR BULK MATERIALS Russian patent published in 2021 - IPC B01F9/08 B01F11/04 B28C5/18 

FIELD: cattle breeding; chemical industry; construction; food industry.

SUBSTANCE: mixer related to drum-type mixing devices for mixing bulk materials in the production and supplementation of animal feed, chemical, construction, food industry is proposed, which has a basic spatial hinge mechanism that allows the mixing drum to perform spatial motion, regulated during operation by two separate drives, where, in order to intensify and increase the efficiency of the mixing process, as well as ensuring the reliability of the mixer, a drum with two diametrically opposite trunnions, which is one of the links of the spatial six-link mechanism with rotational pairs, is hingedly mounted with possibility of rotation around these trunnions on two intermediate cranks, the axes of rotation of which also move in space by means of two support cranks, each of which is driven into rotation by a separate geared motor, and the axes of rotation of the support cranks lie on the same line, the length of the cranks is equal to and half the distance between the geometric axes of the trunnions, the crossing angle of the geometric axes of the hinges of one support crank complements the crossing angle of the axes of the second to 180°, the crossing angles of the hinge axes and the length of the intermediate cranks are the same, and the ratio of the length to sine of the crossing angle of the hinge axes at the intermediate cranks is equal to the ratio of the corresponding parameters of the support cranks.

EFFECT: elimination of the shortcomings mentioned above, as well as increased functional characteristics of the mixer by providing possibility of changing the law of motion of the drum (and, if necessary, even during its operation).
