Description

Изобретение относится к сельскохозяйственному машиностроению и может быть использовано в конструкциях жатвенных машин для уборки зерновых культур.The invention relates to agricultural machinery and can be used in the construction of reaping machines for harvesting crops.

Известна жатка, содержащая корпус, питающий транспортер и выбросное окно [1]Known header containing a housing, a feeding conveyor and an exhaust window [1]

Однако, в такой жатке происходит зависание Стеблей при сходе их с транспортера.However, in such a reaper, the Stems freeze when they exit the conveyor.

Известна валковая жатка, содержащая, корпус, режущий аппарат, вдоль которого размещены два встречно вращающихся питающих транспортера с расположенным между ними выбросным окном и удлинители питающих транспортеров, расположенные со стороны выбросного окна [2].Known roll header, comprising a housing, a cutting apparatus, along which are placed two counter-rotating feed conveyors with an exhaust window located between them and extenders of the feed conveyors located on the side of the exhaust window [2].

Однако данная жатка образует слабо связанный валок.However, this header forms a loosely coupled swath.

Цель изобретения — образование более качественного валка.The purpose of the invention is the formation of a better roll.

Указанная цель достигается тем, что удлинители выполнены в виде шарнирно установленных со стороны питающих транспортеров дополнительных транспортеров, связанных с кривошипно-шатунным механизмом привода, при этом кривошипы привода дополнительных транспортеров установлены в противофазе.This goal is achieved by the fact that the extension cords are made in the form of additional conveyors pivotally mounted on the supply conveyor side and connected to the crank drive mechanism, while the additional crank drive cranks are installed in antiphase.

На чертеже изображена описываемая валковая жатка.The drawing shows the described roller header.

Валковая жатка включает корпус 1, ре5 жущий аппарат 2, вдоль которого размещены два встречно вращающихся питающих транспортера 3 и 4 с расположенным между ними выбросным окном 5. Со стороны питающих транспортеров шарнирно установлены дополнительные транспортеры 6, свя¹⁰ занные с кривошипно-шатунным механизмом привода, при этом кривошипы 7 и 8 установлены в противофазе на вращающем валу 9 и связаны с транспортером при помощи шатуна 10 и кронштейна 11.The roll header includes a housing 1, a cutting apparatus 2, along which two counter-rotating feed conveyors 3 and 4 are placed with an exhaust window 5 located between them. Additional conveyors 6 are pivotally mounted on the supply conveyors side, ¹⁰ connected to the crank drive mechanism, while the cranks 7 and 8 are installed in antiphase on the rotating shaft 9 and are connected to the conveyor using a connecting rod 10 and an arm 11.

Во время работы жатки вращение ведущего вала 9 через кривошипы 7 и 8, шатуны 10 и кронштейны 11 передается дополнительным транспортерам 6, которые совершают колебательное в противофазе движение.During the operation of the header, the rotation of the drive shaft 9 through the cranks 7 and 8, the connecting rods 10 and the brackets 11 is transmitted to the additional conveyors 6, which make an oscillating in antiphase movement.

Потоки стеблей во время движения жатки поступают с питающих транспортеров 3 и 4 на дополнительные транспортеры 6, с которых по различным траекториям укла4 дываются в валок. Попеременное изменение направления встречных потоков способствует интенсивному переплетению стеблей при укладке валка на стерню, т. е. создается структура валка с повышенной связностью стеблей в нем. ⁵ Stem flows during header movement come from the feed conveyors 3 and 4 to additional conveyors 6, from which they are stacked along various trajectories4. An alternating change in the direction of oncoming flows contributes to the intensive interlacing of the stems when laying the roll on the stubble, i.e., a roll structure is created with increased stalk connectivity in it. ⁵

В результате высокой связности валка обеспечивается надежное зависание валка на стерне во время его сушки и дозревания, минимальные потери по подборе.As a result of the high connectivity of the roll, reliable hovering of the roll on the stubble during its drying and ripening is ensured, and minimal selection losses.

Claims

FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used in the construction of harvesting machines for harvesting grain crops. The header, the housing, the feed conveyor and the outflow port 1 are known. However, in such a header the Stalks hang as they leave the conveyor. A roll roll header is known, comprising a housing, a cutting apparatus along which two counter-rotating feed conveyors with a discharge window located between them and extension cords of the feeding conveyors located on the side of the discharge window 2 are located. However, this header forms a weakly coupled roll. The purpose of the invention is the formation of a higher quality roll. This goal is achieved by the fact that the extension cords are made in the form of additional conveyors that are hinged on the side of the feeding conveyors and are connected to the crank-schatunny drive mechanism, while the drive axes of the additional conveyors are installed in antiphase. The drawing shows the described roll reaper. The roll header includes a housing 1, a cutting unit 2, along which two counter-rotating feed conveyors 3 and 4 are placed with an outflow window 5 located between them. On the feed conveyors side, additional conveyors 6 are hinged, connected with a Krivostipno-connecting rod drive mechanism cranks 7 and 8 are installed in antiphase on the rotating shaft 9 and are connected to the conveyor by means of a connecting rod 10 and a bracket 11. During operation of the header, the rotation of the driving shaft 9 through Krivoshchypa 7 and 8, the connecting rods 10 and the brackets 11 in front There is an additional conveyor 6, which make oscillating in antiphase movement. During the movement of the harvester, the stems flow from the feeding conveyors 3 and 4 to the additional conveyors 6, from which they are placed in a swath along various paths. Alternately changing the direction of the opposing streams contributes to the intensive interweaving of the stems when laying the swath on the stubble, i.e., a roll structure with an increased connectivity of the stems in it is created. As a result of the high cohesion of the roll, a reliable hang of the roll on the stubble during its drying and ripening is ensured, with minimal selection losses. The invention of the Valkov reaper, comprising a housing, a cutting apparatus, along which two counter-rotating feed conveyors with a discharge window located between them and extension cords of the feeding conveyors installed on the discharge port side are located, characterized in that, in order to form a better roll The extenders are made in the form of pivotally mounted on the side of the feeding conveyors of additional conveyors connected with a curvature-connecting rod drive mechanism, while the curvature of the drive For more conveyors mounted in opposition.
