Abstract

FIELD: agriculture.

SUBSTANCE: device contains intermediate piece, inclined chamber, harvester window and device of transverse-longitudinal duplicating. Intermediate piece is connected to harvester by device of transverse duplicating, and with inclined chamber of combine is connected by device of longitudinal duplicating of field relief. Device of transverse duplicating consists of placed on harvester of rollers, which are drive by located on intermediate piece grooves, that provides harvester at duplicating leaning to the right and to the left. Device of longitudinal duplicating consists of joint, connecting intermediate piece and inclined chamber of combine. Joints provide for harvester together with intermediate piece to deflect upward and downward, providing longitudinal duplicating.

EFFECT: removing of gaps between mechanisms and loss enhancement of harvest.

Description

The invention relates to agricultural machinery, in particular to grain harvesting machines used for combing crops on the vine.

Known reaper roll hinged / 1 /, containing the balancing mechanism, balancer, horizontal longitudinal hinge, blocks of compensation springs.

The disadvantages of this mechanism are the inability to provide sealing of the header and combine connections and the associated grain loss resulting from the air flow inside the comb header.

A device for hanging the header on the combine / 2 /, providing a connection of the header with the combine and copying the header of the field relief.

The disadvantage of this device is grain loss during harvesting by combing headers, creating an air flow in an aggregate with well-known combine models due to unsatisfactory quality of seals and large gaps in the connection of the spacer and header that occur when the header is swinging during copying of the field topography.

To eliminate the noted drawbacks, the spacer is connected to the header by the transverse copying mechanism, and is connected to the combine tilting chamber by the longitudinal relief field copying mechanism, the transverse copying mechanism is made in the form of rollers mounted on the end surfaces of the header window, in contact with grooves located on the end surface of the spacer, located in concentric circles, and its fixing rollers installed in the upper part of the header window in contact with the back of the brackets rostavki and rollers mounted in the bottom of the spacer in contact with the yokes, secured to the bottom of the header box, and the mechanism includes a copy of the longitudinal cylindrical articulation feeder and spacers located in the lower part of the spacer.

The aim of the invention is to reduce grain losses resulting from the air flow inside the stripping header when aggregating it with known models of combines.

Figure 1 shows the kinematic diagram of mounting the stripping header on the combine.

Figure 2 shows the mechanism of transverse copying of the relief of the field.

Figure 3 shows a spacer with a longitudinal copying mechanism.

A device for hanging stripping reapers on the combine contains a spacer 1 (Fig. 1, 3), an inclined chamber 2 (Fig. 1), a longitudinal-transverse copying mechanism 3 (Fig. 1, 2), consisting of a reaper window 4, rollers 5, grooves 6, rollers 7, brackets 8 and clips 9 (figure 2), providing transverse copying, as well as a cylindrical swivel joint 10 (figure 3), providing longitudinal copying of the field relief.

The device operates as follows.

When the combine moves along the field, the header encounters irregularities of the field, copies them, tilting laterally and rising and lowering longitudinally relative to the direction of movement of the combine using the longitudinal-transverse copying mechanism 3, and rollers 5 located on common concentric circles with radii R ₁ and R ₂ at transverse rolls of the header left and right, move along the grooves 6 located on the spacer, providing transverse copying of the relief of the field. Rollers 7, supported by brackets 8 in the upper part of the header and captured by clips 9 in the lower part of the header, allow the header to tilt left and right, while ensuring a tight connection between the header window 4 and the spacer 1.

During longitudinal raising and lowering of the header, together with the spacer, they rotate in cylindrical swivel joints 10 relative to the inclined chamber of the combine, and the header is returned to its original position by springs available on all known combines with spring-mechanical type copiers.

The joints of the spacer with the header and the spacers with an inclined chamber located in different geometric planes can eliminate the gaps between these mechanisms, and the insignificant gaps that have arisen in the joints can be filled with sealing material, thereby eliminating grain losses in the air flow through these gaps.

The application of the proposed technical solution allows to reduce crop losses behind combing headers and aggregate this type of headers with well-known combine models.
