The invention relates to agricultural machinery, in particular to separators for the rapid analysis of coriander seed.

The invention is an improvement in the separation efficiency of coriander seeds.

Figure 1 shows a diagram of a separator at the time of feeding the seed mixture, side view; Fig. 2 shows the same, in the period of weed seeds weeping by calibrating holes; on fig.Z - that e, in the period of lifting the carrier frame 15 of the separator; Fig. 4 shows the same, during the period of separation of the seeds of an aspherical shape with an outer one, and of coriander fruits with an inner surface of a hollow roll; Fig. 5 shows the same, in the period of the separation of aspherical and rough seeds of both the outer and the inner surfaces of the hollow roll; 6 is the same during the period of the transfer of seeds from the outer to the inner surface 25 of the hollow roller; figure 7 - view And figure 6.

The separator includes; t carrier frame 1, fixed to the axle 2 with the help of hinges 3, roller-feeder 4 s

hopper 5. loading device and a reflective brush 6 mounted on frame 1 horizontally and parallel to each other, rollers 7 and 8, of which roller 7 has an internal cavity lined by friction material 9, and profile cams 10 at the ends, interacting w) le profiled surfaces with deflecting rollers 11 of the base 2, guides the flaps 12-14 and receivers 15-17 seeds.

On the surface of the roller-feeder 4, a series of cells 18 is made parallel to the axis of the roller. The profiles of the external surfaces of the grooved, roller 7 and smooth roller 8 form a melodious gage apertures of a triangular shape. On the roller 7, the paraplecular axis is cut through a longitudinal slit connecting its outer and inner surfaces. Rollers 4 and 7 are rotatably synchronized. Drive roller 4.7 and 8 is not shown. The cams 10 and the rollers 1 1 form a mechaputism of swinging the frame 1.

The separator works.

The i8 rollers-feeder 4 cells take out 5 seeds from the bunker, while the brush 6 holds in the bunker 5 on the surface of the vapik-4 feeder seeds that do not fall into the cells 18. At the time of the seeds fall out of the cells 18 (Fig. 1), the roller 7 occupies a position in which its slit is closed by a flap 12. Seeds that have fallen out of cell 18 of shaft 4 fall between shaft 7 and 8 and are distributed through the holes formed by the surfaces of rollers 7 and 8. At the time of delivery to the inner the cavity of the roller 7 are the seeds that were previously screened at the previous revolution of the roller 7.

In the process of further rotation of the rollers 7 and 8 (Fig. 2), small seeds are sifted through the calibrating holes between these rollers into the receiver 17 under the calibrating holes. Large seeds with a roller 8 are held in the grooves of the grooved roller 7. The seeds on the inner surface of the roller 7 with annular grooves are arranged depending on the shape and surface roughness. The coriander spherical fruits roll in the lower part of the inner cavity of the roller 7 and occupy positions shifted from the vertical passing through the axis of rotation on the coal from oi to oi., Oi,. Less rounded and more rough weed seeds are located higher within the angles from (, to / 3i / b,. When making the working surface of the friction material in the form of a corrugated, surface with tapering

shake the frame 1 with rollers 4,7 and 8 relative to the base 2. At the same time, as the angle between the vertical passing through the seeds and the tangent to the surface of the roller 7 increases, the grooves of the roller 7 will begin to vyosit oblong-shaped seeds with a rough surface, as well as ruffled 10 perianth blooms .. Seizure of the seeds with ruffled, deformed perianths occurs as follows: the initial grooves of the roller 7 raise the seed at T5 a certain angle, then these seeds

roll into calibration holes. At the moment of meeting with the surface of the roller 8, the perianth seeds of the seeds are subjected to elastic deformation by forces of inertia and are wedged in the grooves of the roller 7. Oblong weed seeds are oriented by the walls of the grooves of the roller 7 along the longitudinal axis of the grooves. In this case, the movement of these seeds relative to the surfaces of the grooves becomes possible only due to sliding, since the friction sliding angle is smaller than the tipping angle in the plane of the longitudinal axis of the seed.

Seeds that are wedged in the grooves of the roller 7, as well as the friction removed from the gage holes, are subsequently delivered by the grooves of the roller 7 to the additional receiver 15.

 The seeds on the inside of the surface of the roller 7 are alternately outputted by the roller gap 7. The first easily falling fruits come out.

 -d, l ,, An coriander in the receiver 16 (figure 4). A more effective weed seed is obtained by removing 40 seeds of weeds, the separation of coriander fruits and seeds and weeds. The grooves do not interfere with the rolling of the spherical fruits of coriander, and weed seeds orient the longitudinal axis along the grooves. At the same time, weed seeds are deprived of the possibility of moving along the grooves by rolling (tilting in the plane of the longitudinal axis). Since the weed seeds are moved along the skids, and since the friction friction angle is greater than the rolling friction angle, weed seeds will be located on the inner surface of the roller 7 above the coriander fruit.

those that are not so rounded and the walls of the slit move along the surface of the guide plate 14 to the receiver 17 (Fig. 5). From this moment on, the internal cavity of the roller 7 is free from seeds, and on the external surface, in the grooves of the roller 7 against the calibrating holes, there are unsolicited coriander fruits and non-isolated weed seeds.

In the process of further rotation of the rollers 7 and 8 (Fig. 6), the slit of the roller 7 fits to the roller 8, and the seeds that were previously in the grooves of the roller 7 against the calibrating holes roll over the back wall of the slit into the internal cavity of the roller 7.

In the process of further rotation of the rollers 7 and 8 (FIG. 3), the cams 10 through 2624

shake the frame 1 with rollers 4,7 and 8 relative to the base 2. At the same time, as the angle between the vertical passing through the seeds and the tangent to the surface of the roller 7 increases, the grooves of the roller 7 will begin to vyosit oblong-shaped seeds with a rough surface, as well as ruffled 10 perianth blooms .. Seizure of the seeds with ruffled, deformed perianths occurs as follows: the initial grooves of the roller 7 raise the seed at T5 a certain angle, then these seeds

roll into calibration holes. At the moment of meeting with the surface of the roller 8, the perianth seeds of the seeds are subjected to elastic deformation by forces of inertia and are wedged in the grooves of the roller 7. Oblong weed seeds are oriented by the walls of the grooves of the roller 7 along the longitudinal axis of the grooves.

 The seeds on the inside of the surface of the roller 7 are alternately outputted by the roller gap 7. The first easily falling fruits come out.

- Ap coriander in the receiver 16 (figure 4). Weed seeds fall out,

those not so rounded and the walls of the slit move along the surface of the guide plate 14 to the receiver 17 (Fig. 5). From this point on, the inner cavity of the roller 7 is free of seeds, and on the outer surface, in the grooves of the roller 7, against the calibrating holes, there is a loose coriander fruit and non-isolated weed seeds.

   weed seeds fall out

In the process of further rotation of the rollers 7 and 8 (Fig. 6), the slit of the roller 7 fits to the roller 8, and the seeds that were previously in the grooves of the roller 7 against the calibrating holes roll over the back wall of the slit into the internal cavity of the roller 7.

In the process of further rotation of the rollers 7 and 8, the slot of the roller 7 goes beyond the shield 12, the seeds fall out of the cells 18 of the roller 4, and the process of weed seeds separation is repeated.
