Description

(54) TRIER

one

The invention relates to grain cleaning machines and is intended for the separation of granular mixtures into fractions differing in length.

The known Trier, consisting of an endless, elastic cellular tape located between the drums, discs and guide rollers, a device for reflecting a long fraction, a feeding device and grooves for receiving fraction 1.

However, in this trimer, butt loading, not across the entire width of the tape, the reflected particles protruding from the cells return many times to the working area, which reduces productivity.

The closest to the proposed for the performed function and the achieved result is the Trier, including the body, the working body, made in the form of an infinite, flexible cellular tape installed between the drums and the discs, the device for removing long particles, the loading and unloading device, the drive 2

The disadvantage of the known Trier is that it does not provide a clear separation of the mixture into fractions by length due to

the fact that long particles are stacked in cells and short on top of them. In this case, the reflector is thrown into the receiver of the long fraction, and those and other particles, which reduces the clarity of separation. In addition, excessive energy is spent on the reflection of long particles, since their direction of motion changes from the opposite. The possibility of injury to the particles and a sharp increase in specific energy consumption limits the speed of the cellular tape and, consequently, the performance.

The purpose of the invention is to intensify the separation process.

This goal is achieved due to the fact that the Trier is provided with a limiter and a divider, made in the form of POSE, set tangentially to the cellular tape in the ejection zone of the fractions, and the device for removing long particles is made in the form of a paddle drum mounted on the shaft coaxially with the disks while the drum and the tape have the same direction of movement, and the speed of the drum in the zone of interaction with the tape provides for a relative displacement of their surface
