Description

one

Known combine harvesters, including the upper sieve mill with extension, and the chamber kopnitel.

Their disadvantage lies in the fact that when harvesting grain crops clogged by poisonous weeds, the latter get into the threshing machine, are crushed together with the bread mass, forming dust containing poisonous alkaloids, which, falling on grain, straw and harvested, makes them deadly.

In order to ensure a more complete cleaning of grain and straw from the dust-like elements of the dovit weeds, by removing them to the ground with mine, mine stacker in the proposed harvester, a window is formed in the bottom of the semi-nailer, and a removable damper is installed in front of the window. The drawing shows the proposed combine harvester.

The combine harvester has ordinary working bodies designed to carry out the process of combine harvesting, both direct and separate.

The threshed and selected grain enters the upper sieve mill 1 with extension 2, then chaff and tail, coming out of the upper sieve mill, goes to the bottom 3 of the half grinder, in which window 4 is formed, and outside the window, in front of the hopper 5, a removable valve 6 is installed. Shutter can be

at one end, the polonabivatel is fastened on the shaft 7 after removing the tine from it, and the other end is fastened on the edge of the bottom of the polonabivatel behind the window.

The proposed combine works as follows.

Cut dry stalks of plants by means of a mounted pick-up and a conveyor located in an inclined chamber for feeding the threshed mass enter the threshing chamber of the thresher, and from there to the threshing device.

The threshing drum captures the grain mass, drags it through the gap between it

and deck, subjected to both strong and frequent shocks and rubbing.

As a result, the grain is released from the ears. At the same time, most of the grain and grain passes through the holes of the deck and falls on

bolt. During the selection and threshing of the combine, the weeds are crushed, and the dry poisoned elements only pollinate the elements of the pile. The heap obtained after threshing is thrown out by the drum and strikes the beater, which, rotating in the same direction as the drum, reduces the speed of the heap and changes its direction. Due to this, the heap is ground by grinding and grain is extracted from it. The beater contributes to pushing the straw mass onto the keyboard walker, where

under the action of a shaking motion, the grain is separated from the straw. At the same time, a small pile containing the main part of the grain fills the straw walker's cells, while the large pile is placed on top of its slats. When descending from the straw walker, a small pile on the page of the pitched plank enters the upper reshatny mill of the cleaning device. When a large pile is transported to the exit of the thresher, when exposed to a salt mill and a fan, the remaining grain is extracted in it and, together with other small impurities, is sent along the ramp to the grate mill.

Straw straw is sent to the hopper chamber. A small pile, which entered the upper grating mill, under the influence of the air flow from the fan and the oscillations of the mill, is divided into three fractions: grain, small impurities, and remnants of unmolded ears. Grain, standing out under the lower sieve mill, enters the grain auger along the pitched board. The remnants of the unmilled ears, standing out at the end of the upper sieve mill and through the extender holes, are fed into the auger auger along the pitched board and

served by a grain elevator to the receiving grinder for re-threshing. Light impurities, along with pulverized, poisonous elements, are carried away with air and are thrown out of the window, mine aspirator. The optimal air flow in the cleaning device is regulated at nomosh, and the dampers of the entrance windows of the fan and the extension of the upper sieve mill. At the same time, the air flow mode does not depend on the filling of the hopper with straw and can be selected optimally, not changing in the course of work.

Subject invention

Combine harvester, including an upper sieve mill with extension, floor shearer and hopper chamber, characterized in that, in order to ensure more complete cleaning of grain and straw from dust elements of weedy by weeding them to the ground with a bad mine mine, the stacker is formed at the bottom a window, and outside the window, in front of the hopper, a removable flap is installed.
