Description

one

The invention relates to the technique of sorting various materials and can be used in the preparation of food from food waste in feed houses of livestock farms and farms.

The purpose of the invention is to improve the quality of sorting by providing separate unloading of bones and non-food wastes.

FIG. 1 shows a device for gravitational sorting along the longitudinal axis; in fig. 2 - sorting surface at the zero position of the duct, top view; Fig 3 - the same, with the working position of the box; in fig. 4 - box, longitudinal section.

The device for gravitational sorting (Fig. 1) consists of a chute having a bottom 1 and parallel walls 2 mounted on a frame 3, kinematically connected to a drive 4 and using flexible connections 5 to a base 6. In the slot of the bottom 1 is rigidly fixed flush with the bottom 1 is the bottom of the box 7. A box 9 is attached to the front wall 8 by means of hinged suspensions, mounted on the bottom 7, which in the upper part has a wing 10 located on the bottom 1 of the groove and entering the grooves 11 of the parallel walls 2 of the groove. The rear wall 12 of the box 9 is also connected hinged to its side walls. To remove the sorted product, a discharge tray 13 is rigidly attached to the box. The side walls of the box are connected by a screw pair 14, which rotates the box 9 relative to the longitudinal axis of the device to remove the sorted product.

The device works as follows.

Before starting work, the box 9 should be set to the zero position, i.e. perpendicular to its longitudinal axis (Fig. 2). Non-edible inclusions are fed to the bottom 1 in the chute loading area, which performs reciprocating movements from the actuator 4 and vertical displacements due to flexible links 5. Moving, non-food waste fills the duct 9 and part of the discharge tray 13 (Fig. 4), The weight distribution is as follows: the bones (as lighter) are collected from above, and the stones, metal, glass and other waste are located below. In this case (Fig. 2), for each inclusion of the sorted product, located in the box 9, there is a force directed along the axis of the device, so unloading from the tray does not occur. To unload the sorted product by screw pair 14, it is necessary to rotate the box 9 until this sorted product starts to be unloaded from the box 9 along the discharge tray 13 under the influence of a component force directed along the axis of the box 9.

At this time, the passage in the discharge tray 13 for the bones located at the top remains permanently blocked by the sorted product, so they, all the time at the top, continue to move only along the longitudinal axis of the chute to the hopper (not shown) and are used to prepare flour.
