Abstract

The invention relates to the field of agriculture, mainly to devices for the separation of a mixture of seeds according to physicomechanical properties, and used in the mining and construction industry. The purpose of the invention is to improve the quality of separation by allowing different modes of vibration impact on the components of a mixture of seeds of various sizes.

On the cylindrical surface of the drum perpendicular to the axis of rotation there are annular grooves (CC) with a triangular profile in section, in which at the moment of filling small seeds fall into the lower zone, the middle and large ones respectively into the intermediate and upper zones. The feed ends in the QC are located under each other, by-pass trays 8. They separate the seeds from the corresponding QC zones into concentrated fractions by seed size. The fractions are fed to the inclined friction surfaces (P) 3 of the vibrating table 5.

Description

The invention relates to agriculture, mainly to devices for the separation of a mixture of seeds according to physicomechanical properties, and can be used in the mining and construction industries.

The purpose of the invention is to increase the quality of separation by providing the possibility of different modes of vibratory airing to the components of a mixture of seeds of various sizes.

FIG. 1 shows a separator diagram; in fig. 2 - the same, top view; in fig. 3 - drum grooves, side view, section.

The separator consists of a hopper 1 with a feeder of classifier 2 for separating seeds by size in the form of a drum, into annular grooves, and having a triangular profile in the cross section, a vibrating table with a package of inclined friction surfaces 3, a vibrator with a drive 4. Surfaces 3 mounted on the vibrating table 5, which through the elastic elements 6 is mounted on the support 7. The material from the classifier 2 on the surface 3 is supplied with the inclined trays 8 installed one below the other, each lower surface 3 of the mouth The inclination is greater than the surface above. Separation products are collected at receivers 9-11. The trays are installed boot ends in the annular grooves of the drum.

The separator works as follows.

From the hopper 1, the seed mixture flows to the side surface of the rotating drum 2 and is evenly distributed over its surface while simultaneously filling the annular grooves made on the side surface perpendicular to the axis of rotation. B. The time of filling the annular grooves of the material particles are distributed depending on their size: in the lower zone - a layer of small, in the intermediate and upper - a layer of medium and large particles of the material, respectively. In the annular grooves meet

the rotation of the drum 2 posted bypass trays 8, providing separate selection of particles from the respective zones of the grooves, with the formation of concentrated fractions

(at least two) in particle size. After descent from the surfaces of the discharge chutes 8, the separated fractions enter the friction working surfaces 3, where they are separated under the influence of vibration effects: each separate fraction on the corresponding surface, set at the required angle of inclination to the mountains, due to the difference in physical and mechanical properties isolated fractions. Divided by size and properties

surface fractions are collected in receivers 9-11 located around friction surfaces 3.
