Description

Tongue cleaning machines and others are known in agriculture for processing and seeding seeds, made in the form of a drum with a screw located in the casing, through the forming surface of which the fruit is passed, and the seeds move to the end wall of the casing to exit him

Infusion w, its proposal is different in that under the screw, parallel to its axis, are rollers, which are rotated in pairs to meet each other in order to remove the fruit from the screw.

FIG. 1 is a side sectional view of the machine; in fig. 2 - view of the machine from the drive side; in fig. 3 is a cross-section of the drum along BB.

In the housing 1, equipped with a feed funnel, the shaft 2 rotates, initially having a tapered, then cylindrical shape, with the tapered and adjacent cylindrical parts of the shaft fitted with screw blades 5. Longitudinal strips 4 are mounted on the cylindrical part of the shaft

provided at the end with a drive handle 5, which, in the case of using a mechanical drive, can be replaced with a pulley. Gear 6 is mounted on the end of the shaft, driving rollers 7 through intermediate gear 10 and gear 5 meshed with it mounted on the axis of the rollers 7. Under the rollers there are strips 9 designed to clean the rollers from sticking to them.

Tung fruits are fed by an auger from the feed hopper and directed into the cavity between casing 7 and shaft 2. The clearance between the casing and the shaft is smaller than the diameter of the fruit, as a result of which the latter is destroyed and the material is retracted from the auger to the outside by rollers rotating in pairs towards each other. The gaps between the rollers are set so that the seeds of the fruit do not pass through the nig, under the rollers, but are directed by the screw to the end of the casing, where, mixing, the bars 4 would finally be cleaned and after that through the window 1 would exit to the end of the casing.
