Description

Machines for sorting of root crops and fruits are known, equipped with a sorting screen in the form of a lattice formed by longitudinal conical directions, under which rods are located in the transverse direction with rollers (rollers) freely attached to them, while the ends of the rods are mounted in parallel to the mounted threaded directions with IMS; thread pitch in the direction of movement of the working branch (for example, German patent No. 853670).

A distinctive feature of the described device for sorting fruits is that the rollers forming the sorting sheet are transversely fixed on the links of the chain conveyor, and in the intervals between the rollers on the links of the chain the rollers interact with the movable tire located above the working branch transporter.

A device of this design provides the necessary adjustment between the rollers.

In addition, the working branch of the chain conveyor of the proposed device can be equipped with drive wheels at the beginning and end.

FIG. 1 shows schematically the described device in section; in fig. 2 shows sections along A-A and B-B in FIG. one.

The drive and guide wheels 1, 2, 3, and 4 of the chain conveyor are installed on the device mill by means of shafts. To the chains of the conveyor are mounted transversely mounted rollers 5, forming a sorting sheet.

Each chain link consists of two pivotally attached levers b and 7, on one of which roller 8 is attached. The rollers move

No. 146119 - 2 along the tires 9 located on each side of the device above the conveyor chains.

The rollers, in turn, roll over tire 10, which limits the movement of the rolls down. Tires 9 interacting with the rollers can change their position in height along the axis of the sorting sheet. The adjustment of tires 9 in height is carried out with screws // and 12. Depending on the position of tire 9 relative to tire 10, the distance between the axles of the rollers along the sorting screen may be variable. Due to the presence of two driving wheels, the conveyor chain is evenly loaded.

The products to be sorted are fed through the loading device 13 to the sorting rollers 5, which by means of a conveyor chain are rolled at an increasing speed along the working chain of the conveyor. The distance between the rollers in the direction of their movement increases. As products move, the latter fall between the rollers, the distances between which are equal to the diameter of the products (fruits).

The graded fruits enter the receiving bins 14. Too large fruits are removed from the device through the tray 15.

The described device can be used for sorting fruits and root crops.

Claims (2)

1. A device for sorting fruits by size, including a sorting bed formed by rollers, the distance between which gradually increases in the course of movement, characterized in that, in order to adjust the distance between rollers depending on the need, the latter are transversely fixed to links x chain conveyor, and in the intervals between the rollers on the links of the chain, the rollers interacting with the movable band located above the working branch of the conveyor are also hinged. 2. The form of the device according to claim 1, characterized in that the working branch of the chain conveyor is equipped at the beginning and in the end wheels. about / nofl-H
