Description

FIELD OF THE INVENTION The invention relates to combine harvester units.

Known mechanisms of attachment of the frontal screw header of a combine harvester include elements K | repleni llatform header of the header to the body of an inclined conveyor, made in the form of upper and lower swivel links, forming together with the platform of the inclined conveyor four-piece.

However, the introduction of polymorphic links complicates the mechanism of hinge, in addition, their implementation in the metal is also difficult.

In order to simplify the design of the proposed mechanism, the connection of the upper link to the header platform is a shaped groove in the housing of the inclined conveyor with at least one roller mounted on the header platform.

The upper pivot link can be formed by two pairs of rollers and shaped grooves located on the sides of the body of the inclined conveyor in pairs.

FIG. 1 shows schematically the proposed header, side view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - bottom noBoipOTHoe link, top view; in fig. 4 is a section along BB in FIG. 3

The hinge mechanism contains elements of a movable joint (platform 1 of the header with body i2 of an inclined conveyor 3, as well as elements 4 of equilibration of the platform.

Elements of the movable connection of the platform 1 with an inclined body 2 include the lower 5 and upper 6 rotary links.

The lower pivot link 5 is a rod 7 connected to the inclined body 2 by means of an axial hinge 8 and with a platform 1 - a spherical hinge 9. The upper pivot link 6 is formed by two pairs of interacting rollers 10 and figured grooves I.

Each of the rollers 10 is installed on the horizontal axis 12 of the platform 1.

Each of the figured grooves 11 is made as mounted on the inclined body 2 and the corresponding roller 10, developed by the Height of the figured cage 13. When platform 1 does not have an angular displacement relative to the inclined body 2 in the transverse direction, the rollers 10 are arranged in cages with the possibility moves both vertically and horizontally. The restriction of the movement of the rollers in the transverse direction excludes the rotation of the platform 1 in the horizontal plane without additional means,

The parameters of the lower pivot link 5 and the configuration of the clips 13 are selected with the ability to move Schlatfarm 1 when longitudinally Kolirovanie relative to the inclined body 2 along the arc with 1 center located directly on the axis of the lower drum 14 of the inclined conveyor 3, interacting with the screw 15.

The mechanism of operation is as follows.

In longitudinal copying by the header of a relief lol, the platform connected to the inclined body by the pivoting links of the attachment mechanism moves along an arc defined by the parameters of the links, i.e., along the arc with the center of the lower drum on the inclined conveyor. As a result, the headers of the headers will also move concentrically to the arc, while the gap between the auger and the slats 16 of the conveyor belt will remain constant at all positions of the platform when the header is copied on the floor.

In transverse copying, the platform will move in an arc around the spherical hinge, the rollers attached to it will move along the arcuate surface of the shaped holders up or down with simultaneous axial displacement in the transverse direction.

With both longitudinal and transverse relief relief, the floor elements of the upper

link 5 prevent the platform from rotating in a horizontal plane.

Various options for the implementation of the upper rotary link. It may contain an interconnected roller and a shaped groove located in the vertical plane of the header.
