SU24602A1 - Adaptation to the combine for collecting straw and chaff - Google Patents

Description

The fixture is a wagon attached at the rear of the combine and equipped with three resettables for the purpose of adapting them to various combines, conveyors from which the transverse and longitudinal lower ones are intended to be diverted to one of the two hoppers of the chaff, and the longitudinal upper for directing directly to the same bunker or by means of a beater to another straw bin, whereby the belts of all three conveyors and the beater are driven by a chain and gear transmission from the hub of one of the four wheels of the wagon.

In the schematic drawing of FIG. 1 shows a longitudinal vertical section of the tool; FIG. 2 is a longitudinal section of the same fixture along A B of FIG. one; FIG. 3-cross-section on CD of FIG. one.

The base of the wagon, located on four wheels, is attached to the rear of the combine to the sides of its threshing unit. The walls of the wagon, in order to adapt the latter to combines of various widths, are made adjustable by the width of the wagon.

Inside the carriage there are two longitudinal belt conveyors / 4 and C, the front ends of which, in order to adapt the carriage to harvesters with different positions of straw walkers and screeners, are height-adjustable, thanks to the fastening of these ends in guides E tl. N w. perestavnymi

along the length thanks to the fastening of the guides E and. N in the longitudinal guides 5 and D, and the possibility of extending the conveyors is provided by a spare, length of their webs. Above the rear end of the upper conveyor A is located beater d :. Between the upper conveyor A and the bunker O, located behind the wagon, the valve / is rotatably fixed, turned by means of the handle T, reinforced at the side of the wagon. Under the rear end of the lower conveyor C is a transverse belt conveyor. The Y terminating in bunker K, reinforced adjacent to bunker O. Both longitudinal conveyors and a beater are driven from the hub of one of the four wheels of the wagon by a chain transmission, and the transverse conveyor is driven from the same wheel by a chain transmission and a pair of bevel gears .

The floor comes from the harvester's rumble to the lower conveyor C, dumped from it onto the transverse conveyor U and transferred from the latter to the bunker K. The straw enters the combine straw walker first to the upper conveyor A, and then to the valve /, from where the beater x is dumped into the bunker O. When the valve / is open, which corresponds to the lower position of the handle T, straw is poured from conveyor A onto the cross conveyor U and together with the floor conveyor is fed into one bunker K. As the bins are filled, their back wall leans back and throwing piles on the field. .

The observation of the movement of straw and chaff, as well as the unloading of both products from the bins, is carried out by the worker, which is placed on the platforms H, which are fortified behind the bins.

The subject matter of the invention.

Combine attachment for collecting straw and chaff, characterized by

so that - as attached to the combine

the carriage is installed to be re-installed, in order to adapt them to the different position of the straw walker and floor drainage in different combines, the conveyors A for straw and C and U for the floor, the webs of which receive movement from the running axle of the carriage and which are intended to drain the straw into the bunker O and chaff into the bunker / S, or, with valve 4 open, for feeding both products into one bunker / S.
