Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce the loss of seeds. The header consists of stem lifters 1, forming channels 2 with a lead-in part 3. Part 3 is made in the form of a wedge with apex 4, the direction of the apex of the wedge coincides with the direction of the apex of the angle formed by the side edges of 6 dividers. The wedge angle of part 3 is smaller than the angle formed by the dividers. This embodiment eliminates the clogging of the entrance to the channels with 2 stems and the loss of seeds from falling, allows you to raise low-placed baskets and send them through channel 2 for further processing. The end 12 of the longitudinal edge 11 is folded down and aligned with the edge 13 of the divider. The bend of the edge 11 provides the best entry of the stems into the channel 2 between the stem lifters 1. 2 Cp. f-ly, 2 ill.

Description

The invention relates to agricultural machinery, in particular to reapers for harvesting sunflower and other crops, such as sorghum, and is an improvement of the invention according to the author. St. No. 685185.

The purpose of the invention is to reduce the loss of seeds.

Figure 1 shows the proposed header in the section, side view; figure 2 - the same fragment, the view in the plan.

The header consists of stem lifters 1, forming inclined channels 2 with a lead-in part 3, made in the form of a wedge with apex 4, dividers 5 with side edges 6, conveyors

7 for collecting showered seeds, chain conveyors 8 with a driven sprocket 9 for picking up and advancing the stems in the channels and covers 10 with the longitudinal edge 11 overlapping the channel. The end 12 of the edge 11 in the lead-in part 3 of the channel 2 is bent downward and adjacent to the edge 13 of the face 6 of the dividers 5. The edge 13 is flush with the edge 14 of the lead-in part 3 located on the opposite divider 5.

Reaper works as follows.

When the header moves along the field, the stems are guided by dividers 5 to the lead-in part 3 of channel 2, while the poorly located baskets gradually rise along the inclined end 12 of the edge 11, behind IO VJ

they are grabbed by the legs of the conveyors 8 and are fed through the channel 2 to the inclined chamber of a combine harvester (not shown). The long stems, falling into the lead-in part 3, are also smoothly deflected by the end 12 and freely entering channel 2, with the basket tilting over the conveyor 7 and the showered seeds along the casing 10 rolling onto the conveyor belt 7 and being fed into the inclined chamber of the combine.

Performing the front of channels 2 with the lead-in part 3 eliminates clogging of the entrance to the channels with 2 stems and loss of seeds from falling, and allows low-lying baskets to be raised and directed them through channel 2 to the thresher (not shown) of the combine.

In addition, such an execution of the entrance to channel 2 allows other crops to be harvested with minimal losses, for example, grain sorghum.

Claims (3)

1. Reaper for harvesting sunflower according to ed. St. No. 685185. characterized in that, in order to reduce seed losses, the channel formed by the stem lifters in the lead-in part is made in the form of a wedge with a corner of the corner located behind the side edges of the dividers, and in magnitude - less than this angle, while the end of the longitudinal edge of the casing in the lead-in part is made bent downwards and is adjacent to the edge of the divider. 2. A harvester according to claim 1, characterized in that the edges of the channel opposite to the top of the channel of the lead-in part are located at the same level. 3. The harvester according to claim 1, characterized in that the beginning of the bend of the edge is located between the top of the lead-in part of the channel and driven by an asterisk of the stalk transporter. 7 8 Fm.1 12 W Rig.2
