Description

The pasACvibHOft methods of harvesting grain crops both by the method of separate combining with the use of hoppers for the straw mass, and by the harvesting of the grain mass from the rolls by the chopping units with the subsequent removal by special trolleys for threshing are known. Their disadvantage is the presence of residues of straw mass on the Field, which requires additional costs and time to harvest them .-- to free the field for further processing and preparing it for the next harvest.

A distinctive feature of the proposed method is the complete liberation of the floor from the grain mass and plant residues immediately after the selection of rolls by the selection unit and the storing of straw products immediately after threshing at a steady current. This makes it possible to immediately process the fields for later use.

According to the proposed technology, when harvesting grain with a waxy ripeness of grain, the bread mass, mowed by the headers and packed into rolls, is selected by a picker unit consisting of a header with a pick-up equipped with a special conveyor and a cart for loading the bread mass without crushing it. A loaded trolley is delivered with a tack to a stationary threshing unit consisting of a threshing machine with a receiving and transferring chamber, and a conveyor for feeding the straw mass immediately after threshing to the ichardumformer to form a rye.

FIG. 1 shows a diagram of the collecting unit; in fig. 2 is a diagram of a threshing unit with a skirduer.

The pick-up unit consists of a reaper / on a self-propelled chassis equipped with a pick-up and a special conveyor 2 with a visor 5 feeding the unmilled bread mass into the transport cart 4 attached to the self-propelled schassi. The cart has a trailer and mechanisms for unloading the grain mass into the threshing unit. Upon filling, the cart is automatically uncoupled, and a friend clings in its place. The filled trolley is delivered to the stationary threshing unit with a hitch and mounted on special guides 5 close to the receiving and transferring chamber of the threshing unit. The threshing unit consists of the actual thresher b, mounted on a self-propelled vehicle, a receiving-transfer chamber 7, a grain collector and, a sleeve 9 for unloading grain into vehicles, a transporter Ш of straw products with a valve // distributor and a ricardoformitel 12. Bread mass is pushed out by trolley mechanisms into the receiving and transferring chamber of the threshing unit, from where the feeding mechanisms of the chamber are uniformly fed to the threshing drum using an intermediate conveyor. The threshed and cleaned grain enters the grain container and, in passing, is cast on the automatic weights mounted on the thresher, the sleeve is unloaded into vehicles.

Straw products and chaff are transported along the conveyor belt / 0 into the mow formformer to form a mow. Skirdoformitel.-consists of three pattern 13 (two lateral and one transverse,). As the spaces between the templates are filled with straw products, the transverse template is removed and the threshing unit is moved by dragging the side templates with the help of t 14. This continues until a desired size is obtained. . .

The special design of the transport carts and the flow of grain from the chamber to the threshing apparatus and the grain to the grain container, and the straw products to the maize sharply reduce losses when using new technology compared to existing methods of separate harvesting.

The complex of mechanisms for carrying out the harvesting according to the proposed method, based on the harvesting of an array of 200 hectares, consists of a header on a self-propelled truck equipped with a conveyor and pick-up, two special transport trucks, one ton of low power, one threshing unit with a receiving chamber and a conveyor for straw products and a skiroformitel. ...

Present Invention

Claims (3)

1. A method for separate harvesting of grain crops with threshing of the grain mass in stationary conditions and shaving off straw with the use of garbage formalizer, characterized in that, in order to clean the straw from the straw and conduct it for early use or other work, there is a selection grain mass from the rolls, removal and threshing in stationary conditions are carried out continuously, without grinding the grain mass, with direct stripping of straw products after threshing. 2. A device for carrying out the method of claim 1, characterized in that for the selection of the grain mass from the rolls and its delivery to the current without loss, the self-propelled harvester equipped with a pick-up and loading conveyor with a guide in it, is aggregated with a special trolley with a trailer loaded with the grain mass of the AERIALS of the conveyor and unloaded directly into the threshing chamber of the thresher by means of the unloading mechanism mounted on it. 3. A device for carrying out the method according to claim 1, characterized by the use of a stationary thresher mounted on a self-propelled chassis and equipped with a special receiving-transfer chamber, providing mechanized supply of unground grain to the threshing drums, and a conveyor with a valve distributor for transporting straw products to the ichardooformer.
