Description

Effective isolation of seeds from a pile of various crops, in particular, clover, flax, kok-sagyz, spruce, pine, etc., with a small expenditure of manual labor and with small losses of seeds is a problem in the national economy.

Known for this purpose are lik-kververoterochny machines and grater attachments to; combines are not universal; they give a low degree of wiping of seeds; they require a large amount of manual labor for repeated passes through them and heaps of heaps and are complex in design.

The proposed universal grater-bale is adapted to isolate seeds from a pile of different crops in a single workflow, its use requires a small amount of manual labor, and the device is simple and differs in that for mixing a pile, its large drum mesh casing forms a parallel drum over the drum with a lid, having, for it, reflective ribs located at an angle to the beaters of the drum, provided with grooves tilted in different directions.

FIG. 1 shows a versatile grater in a longitudinal section; in fig. 2 - her mobile drum with a mesh grating.

The grated casing / bilny drum, which has a pear-shaped form in cross section, is made of an entrane grid. The distance between the mesh and the beams can be varied within certain limits with the help of tension bolts, the approach of the housing to the beams, and the radial permutation of the beats. In the upper part of the casing there is a cover 2 with reflective ribs 3 located at an angle to the drum beaters. When the drum 3 is inserted, the ribs 3 promote intensive mixing of the pile in the mixing chamber parallel to the drum formed between the cover 2 and the bilder drum in the upper part of the casing 1. The height of the mixing chamber is approximately ten times greater than the minimum gap between the billes 4 and the casing 1. B chamber mixing a pile under the influence of beat 4 ud№ 97305

rides about the ribs 3 of the lid 2 and loses speed, as a result of which it is subjected to more intense impact of the next bil and better mixing as it advances along the biling drum 5 by the step size between the ribs 3. 3 covers 2 interact with a pile, contributing to its braking and increasing the length of the working path along the surface of the grating drum casing. At the same time, up to 80% of seeds are released from the heap. Under the pitched board 6 below the casing 1 of the grating drum there is a lattice mill of the machine, consisting of four sieves 7, 8, 9 and 10, receiving heap coming from the outlet of the casing of the grating drum. The upper sieve 7 has the form of a flat punch sieve and serves to separate the straw parts from the pile, which prevents the wire sieves 8, 9 and 10 from clogging and increases the productivity of the sieve mill. The space between screens 7 and 8 is blown by the air flow created by the bil drum and removing the light fractions from the heap. To blow out the space between the sieves S and P, a fan was applied. Sieve 9 was fed to tray 12 to bring out seeds of the first grade, and the lower sieve 10 to the tray 13 to bring out seeds of the second grade. The sieve 10 is under the seed and serves to free the seeds from small litter. In order to separate heavy fractions from wind relative sieves 8, 9 and 10, a reflective shield 14 was applied, attached to the frame above the collection / 5m of the iron fractions.

The main shaft of the machine is the axle 16 of the coil drum connected to the fan shaft // belt drive 17. At the ends of the fan shaft there are crankshafts connected 18 to front suspension 19 of a sieve mill.

When using the machine as a machine, i.e., when operating without a screen and a grating drum, the seeds are loaded into box 20, from which they are fed along a chute board 21 to a sieve 8.

Pyzhyna clover or. flax heads are poured on the cover of 22 bales and shifted to the screen 23, after which they pass through all the working parts of the machine. If heavy fractions or free seeds are present in heavy fractions (in collection 15), they are repeatedly passed through the machine.

When rubbing the baskets with the seeds of the kok-sagyz, the screen of the screen 23 is removed and the heap falls asleep in the screen drawer. The sieve 9 is removed and a larger sieve 8 is installed instead of it, to the frame of which a sheet of tin is attached to the bottom. The sieve 7 is also removed, and the edge of the canvas apron 24 is attached to the front support bar of screen 23.

When the flax heads are rubbed and the softwood seeds are not covered, the gap between the grating drum and its casing increases, and the speed of the grated drum decreases.

Subject invention

A universal grater for separating seeds from a pile, provided with a mobile drum in a mesh casing, characterized in that, in order to mix the pile, the casing above the drum forms a parallel chamber with a lid having reflective ribs at an angle to the drum beaters, parallel to the drum, equipped with fluted tilted in different directions. yy go, y
