Abstract

The invention relates to devices for threshing and separation of a heap of grain and is intended for combine harvesters. The purpose of the invention is a uniform distribution of plant mass across the width of separating devices under various working conditions. On the disks of the drum 1 device, the podbickers 6 with scourges 7 and panels 8 are fixed. On the panel 8 there are guiding strips 9. The slats 9 are made flat with the possibility of independent movement and installation at different angles to the direction of mass movement. The slats may be sectional, and each section may be removable. In the space between the deck 2 and the straw walker, at least two guide plates 3 are installed, which can be driven to oscillate. The slats 9 and the flaps 3 are driven to change their position. During mass transfer along deck 2, slats 9 act on it, redistributing it, thus, across the width of deck 2. The shields 3, due to rotation around their vertical axes, increase the uniform distribution of the pile across the straw walker. 3 3. p. F-crystals, 3 ill. 1C cl

The invention relates to agricultural machinery, namely, devices for threshing and separation of grain V.1GO heap, designed for combine harvesters.

The purpose of the invention is the uniform distribution of the plant mass but (iirine of the common devices (deck and straw walker) under different conditions of operation of the threshing device.

FIG. 1 shows the proposed device, side view; in fig. 2 the same, top view; in fig. 3 view A in FIG. 2 (guide bar).

The device contains a threshing drum 1, a repetitive deck 2, guide plates 3 and a straw walker with 4. Drum 1 consists of shaft 5 and discs with podichniki 6, on which bichi 7 and panels 8 are fixed. On a pipa. 1 x S the guide bars 9 are located.

The guide bars 9 are flat and the longitudinal axis of each of them is not perpendicular to the direction of mass movement. Due to this, the bar not only can divide the mass flow into two streams, but also change its direction of movement. The shift in mass flow in the transverse direction will be small. However, by using a different number of slats and having their inclination to the direction of mass movement, it is possible to provide a sufficient shift, i.e., to increase the uniformity of mass distribution across the width of the deck, which helps to improve separapy of the grain through the deck across its width . Each nanca 9 is made with the possibility of independent movement, which allows to ensure a boe, i.e. uniform distribution of Macciii across the width of the deck. Nanki 9 vypolpepy with the ability To To: ibKO mix in folders, but also set at different angles to the direction of mass movement. Nano 9s can be made secniopic and each sectional. At: 1 ton the outer diameter of the planks exceeds the diameter of the scourge. Nano 9 .mo-| -uy mix on the panel as a function of one another, and independently. Independent mixing of the slats can be applied in the case where a water supply imbalance and haymaking unit, a straw walker and a grain-cleaning device are wide in width when there is a bottom; Due to the fact that the guiding nanotubes act on the mass with their frontal outer surface, in order to reduce the weight of the sheet, they can be made in the form of a lattice, and the external end surface is solid. In order to facilitate

the effects of the slats on the mass are made with a narrowing from its base to the outer end surface.

In order to more evenly distribute the straw walker in the space between the deck of the straw walker in the space between the deck 2 and the salt water monitor 4, at least two guide plates have been installed. In order to activate the process of separating the grain from the straw heap, the flaps 3 may have a drive 10 for their oscillation. In order to automate the process of mass distribution across the width of the deck and the straw walker, the plates 9 and shields 3 are driven to change their position.

The device works as follows.

Vegetative mass enters the space between deck -2 and whips 7, where in the process of its movement spikelets thresh, chopping of banter, tey and grain separation through mass and deck 2 occur. At that, 20 during mass transfer through deck 2, slats 9 affect it, its redistribution thereby the base of the deck 2. After the exit from the threshing space, the straw straw falls on the scrims 3, which, due to rotation around their vertical axes, increase the uniform distribution of the pile along the straw walker.

The proposed device allows a more even distribution of the plant mass but the width of the deck and the straw walker, which, Q causes a decrease in grain loss.
