Description

[Detailed description of the invention] The present invention relates to a straw rack structure in the threshing section of a combine harvester, and in particular, the straw rack for performing oscillating sorting toward the threshing section is constituted by a collection of block bodies. Straws with different dimensions depending on the arrangement of block bodies
The rack can be assembled in various ways, the common parts are simple to manufacture and assemble, and the rack has the same functions as conventional straw racks and can be conveniently implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a cross-sectional view of the threshing section mounted on the combine harvester.
6 is a handling room, 7 is a handling barrel, 8 is a supply port, 9 is a dust feed port, 10 is a No. 4 gutter, 11 is an axial flow fan, 12 is a dust exhaust port, 13 is a winnow, 14 is a No. 1 conveyor, 15 is the second conveyor.

B shows the entire swinging sorter, with the crimp net 1 below the handling chamber 6.
The crimp net 16 extends from below to the dust outlet 12 side, and has a grain feeding plate 17 and a sorting plate 18 below the crimp net 16, and a sorting net 19 above the No. 1 conveyor 14. A frame plate 20 for the straw rack is formed around four sides from the lower part to the rear end of the frame plate 9, and a grain plate 21 which slopes from the rear part of the frame plate 20 to the top of the second conveyor 15 is successively arranged.

A shows the entire block body, one plate is bent into a U-shape in the direction of lateral force, and three mountain shapes 2 and 2' are formed on the upper edges of the upright surfaces 1 and 1' on both sides, respectively. The front part of the bottom surface 3 formed between the lower parts of the upright surfaces 1.1' is formed into a downward slope 3a with the front end facing downward, and the front and rear ends of both the upright surfaces 1 and 1' are bent outward at right angles. Connecting plate portions 4.4' and 5.5' are respectively formed to form one block.

Therefore, when assembling the stroke rack of the swinging sorter B, as shown in FIGS. 2 to 5, The rear drawing plate parts 5 and 5' of the next block body A are respectively joined to the front drawing plate parts 4 and 4' of the block body A and fixed by spot welding. The block bodies A are arranged in a row in the front-rear direction, and then the block bodies A are arranged in the front-rear direction in the same manner as described above, at regular intervals on the sides of each block body A in the front-rear direction.

When the blocks A are connected, the block bodies A can be sequentially arranged in the front and rear sides inside the frame plate 20, and can be configured in the same manner as a conventional stroke rack.

During the work, when the straw waste etc. sent out from the dust inlet 9 land on each swinging block body A, it is fed by the chevron 2°2' and the grains fall from the slope 3a as shown by arrow A. At the same time, the second object falls from between the two block bodies A and A on the side and falls onto the second conveyor 15, and the device consisting of the rear end is directly removed from the machine from the dust exhaust port 12. is discharged to.

In this way, the present invention bends one plate material in a U-shape in the direction of lateral force, and has a plurality of chevrons 2, 2' on the upper edges of both upright surfaces 1, 1'.
The front part of the bottom surface 3 is formed into a downward slope 3a, and connecting plate parts 4.4 are provided on both sides at the front and back of the whole.
', 5.5' is refracted to form one block body A,
Since the block bodies A are arranged side by side sequentially in the front and back, when the connecting plates 4, 4', 5, and 5' are joined and connected by spot welding etc., each block body A can be arranged in the front and rear directions. In addition to being able to be connected in sequence, they can also be connected in the horizontal direction as well as in the front-rear direction, and stroke racks with different dimensions depending on the model can be assembled well by using the block body A as a common part. The block body A can be easily manufactured by bending a plate material, and the grains falling from the straw waste being fed by the chevron 2゜2' can be made to flow downward from the slope 3a and can be easily collected as second material. It has features that allow it to be implemented in a suitable manner.
