(54) TRIER

one

The invention relates to a device for separating grain mixtures by seed length with a trimer.

A cylindrical Trier is known, including a cellular cylinder, loading and unloading devices, a device for removing long grains while simultaneously mixing the grain layer,

The disadvantage of this ciliadric triere is low, proizvoditep: Nosty, bulkiness and high metal intensity.

The closest in technical sysystvo and achievable rezulyu atu is a trier, which includes a drum, inside which there is an infinite mesh, j, a tamping device with feed rollers, visors, pressure rollers, brush reflector, receiving chutes.

A disadvantage of the known Trier is the low productivity due to the use of a small part of the working length of the cellular surface.

The purpose of the invention is to increase the productivity of Trier by increasing the degree of filling of the tape cells.

This goal is achieved due to the fact that the working surface of the tape and the associated drum surface are tapered.

FIG. 1 shows a general view of the Trier; in fig. 2 - section aa of FIG.

Trier contains a vertically mounted drive drum 1, inside which is installed an infinite mesh tape 2, pressure rollers 3, bending the tape into the drum in several places, brush reflectors 4. Cellular tape 2, contains three zones; a zone 5 with cell sizes for separating cleaned grain; a correction zone 6 with the same cell size; and a zone 7 with cell sizes for isolating short impurities. Inside drum 1, there are installed r-gutter chutes 8 for receiving mixed impurities, chambers 9 for pre-trapping the mixture consisting

from the main fraction and short impurities, feeding devices, made in the vice rotating feed rollers 10, equipped with guiding peaks 11, having kyzhgrichricheskuyu form and installed so that in the area of them {shmaln.O. and cellular. tape 2 tangents. e to each visor 11 and the cellular surface are parallel or 10 small angles between themselves.

The feed rollers 10 and the guides of the visor 11 contain secures located one above the other (along the generator tape 2) in zones 5, 6 and 7 of the cellular mite 2. The receiving groove 8 is connected to a section of the feeding device located in zone 6 of the tape, gravity grain, wire 12 ,. and the receiving chute 9 is connected .., "with the section of the feeder,; rasiolo--. . in the zone 7 of the ribbon by the gravity grain conduit 13.

; Trier also contains gutters 14 for avlivshpm long impurities, installed-25 under the grooves 8 ,. the gutters 15 for catching the {w of the 1 fraction, installed under the grooves 14,. at the same time, the entrance gaps of complaints 14 are located along the zone 6 of the tape 2, and the entrance slots. the slots of the grooves 15 Q are located along the zone 7 of the tape / 2 (along its vertical forming).

Under grooves 9, grooves 16 are installed to trap short impurities with crevices located along zone 7 of tape 2. Entrance slots of grooves 8 are located along zone 5 of tape 2, and entrance slots of grooves 9 are located along zone 5 and 6 of the tape. 2

Inside the drum 1 is installed bun: ker "17,. you are designed in the form of a pipe with branches for a grain mixture in. zone affected. Step 1 va; shkov 1: 0. In order to accelerate the a; chi grain mixture, the zone of the voyeks; the vyliks 10. a bunker with guiding slope surfaces 18; The value of the grain mix is adjusted by moving the dampers.

1: 9 ..- ..;:. :. ..

The drum 1 is mounted on the support rollers .20, mounted on the lower support plate .2.1 of the frame, and is driven from the pulley 22 of the drive mechanism through the belt.

From the radial movements of the drum, 1 is held with the help of rollers 23 mounted on the upper support plate 24.

The working and matching surfaces of the cellular tape 2 and lamb 1 are made

conical, facing up with large bases.

Trier works .. in the following way. The grain mixture from the bunker 17, along its branches, flows in two zones into the zones of influence of the feed rollers 10, which, rotating with their working elements (troughs of blades, cells, etc.), capture the particles of the mixture and serve them to the guides. e peaks 11 in sections located along zone 5 of tape 2. Peaks 11. direct the grain flow tangentially to h: a dry surface with skor1x: yo, close to or equal to its circumferential cKOpccTiJ.

Particles grain mix, falling on

. cellular surface, instantly gain its speed of movement and under the action of inertial forces intensively westward in cells. The conic shape of the working surface of the honeycomb is also conducive to entering particles into the cells.

The guides of the trumpet 11 direct the notes of the long impurities and the insignificant number of grains from the new one. culture. in zone 6 of the cell surface are leites 2. The grains of the main fraction rise in height in the cells {correction zone 6, impurities of the protrusion. with your ends: above the edges of the cells .... reflectors 4 sweep with h-eista. Above. There are long impurities that are trapped, with grooves 14 and gravity coming out of the Trier. The main fraction grains are carried out under the brushes of the reflectors 4 (in zone 6. of the belt) and in the sections of the program section of the tape by means of pressure rollers 3 are separated into the receiving channels 9, which also receive the grains of the main fraction together with short impurities brushes of reflectors 4 in zone 5 of tape 2 .. Grain mixture, consisting of the main fraction and short impurities, from receiving channels 9 through gravity grain lines 13 enters the zones of influence of the feeding rollers 10 in their sections; Pets 2 located along zone 7, from where along the guiding peaks 11 the mixture falls on the cellular surface of the tape in zone 7 with cell sizes to separate out short impurities. Short impurities sink into the ribbon cells .2, the main mixture is located on the cellular surface of the ribbon. Brush openings 4 are swept from the cellular surface of the grain fraction, which are caught by the bells 15 and the drift is removed from the terrier. Short impurities pass under the children of the reflectors 4 and, in the deflection zones of the cellular tape, are released into the receiving chute 16, from where they are spontaneously discharged from the trieur. .Formula and 3.Obetin and Trier, which includes a drum, inside which is placed infinitely cellular
