Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for lower conveyance in the reaping section of a combine harvester.

That is, a coaxial lower conveyance chain is installed rearward from one side of at least two scraping wheels arranged in parallel above the cutting blade, and a pinning rod installed opposite to the lower conveying chain is connected to the other scraping wheel. Conventionally, in the reaping section of a combine that is configured to extend from the side of the cutting wheel, the support frame supporting the rod is supported from the lower reaping frame side. In the past, there was a drawback that weeds, soil, etc. piled up, which hindered the transportation of grain culms.

The present invention solves these drawbacks, provides a simple structure that allows the trapping rod to be well supported from above so that grain culm transportation is not hindered, and can be suitably implemented.

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

FIG. 1 shows a side view of the combine harvester, with a feed chain 1 on the fuselage supported by crawlers 11.
A threshing section B is equipped with a second class, and a reaping section A is installed in front of the threshing section B.
Each grass dividing board 13 is installed obliquely in front, and each lifting case 14 is installed obliquely behind it, and the cutting blade 1 is installed horizontally across each reaping frame 15 at the rear lower part of each lifting case 14, At the rear of the cutting blade 1, a support frame 16 is installed horizontally across each of the reaping frames 15, and above the support frame 16 there are three rods, each of which has its lower part fixed by a mounting bracket 17, at intervals in the horizontal direction. Support shafts 18, 7, and 19 are installed upright, and the left support shaft 18 has a scraping foil 2, a lower conveyance chain 4, a scraping belt with a protrusion 20 (not shown), and a belt cover 21.
, and the intermediate support shaft 7 is equipped with a scraping foil 3, a scraping belt 22 with a protrusion 20, and a belt cover 2.
3, and a lower conveyance chain 24, a scraping belt with protrusions 20 (not shown), and a belt cover 25 are attached to the right support shaft 19, and both lower conveyance chains 4 and 24 extend rearward so that they can be rotated. The feed chain 12 of the threshing section B is conveyed by the vertical conveyance chain 26 from the rear of both lower conveyance chains 4 and 24.
It is constructed in the same way as the conventional structure by being installed so that grain culm can be supplied to the container.

5 is a clamping rod, the tip of which is attached to the scraping foil 3.
The entire lower conveying chain 4 is located on the upper side.
The scraping foil 4 is formed so as to extend on the working surface of the
Two support rods 27, 27 connected to the support rod 5 are inserted into the support frame 8 located above the rear part of the support frame 8, and the support rods 27, 27 are inserted into the support frame 8 located in the rear upper part of the support frame 8. 5 is installed on the lower conveyance chain 4 side so as to be able to be compressed.

6 is a clamping rod, the tip of which is connected to the scraping belt 2.
2, the entire support frame 9 is formed so as to extend over the working surface of the lower conveying chain 24, and is located above the side of the scraping wheel 3;
Insert the two support rods 29, 29 connected to the support rod 6, and insert the bullets 30, 3 inside the support frame 9.
0, the clamping rod 6 is installed so as to be able to press against the lower conveyance chain 24 side.

A cylindrical metal 31 is fitted to the upper end of the support shaft 7 extending upwardly of the belt cover 23 and fixed with bolts 32, and a pipe support frame 10 with one end fixed to the cylindrical metal 31 is attached to the belt. The top of the cover 23 extends rearward and is bent downward from the middle part C, and both ends of a connecting frame 33 fixed to the lower end of the support frame 10 are joined to the upper surface of the support frames 8 and 9, and two are fixed via bolts 34, 34, respectively.

Therefore, the support frame 10 extending from the upper end side of the support shaft 7 can support both the armrests 5 and 6 from above, and the supporting members supporting the armrests 5 and 6 can be replaced with the conventional support members. Since it disappears on the downward side,
Weeds, soil, etc. no longer accumulate in the vicinity of the rods 5 and 6 as in the past.

In this way, the present invention includes a coaxial lower conveyance chain extending rearward from one side of at least two scraping wheels arranged in parallel above the cutting blade, and a pinning wheel installed opposite to the lower conveyance chain. In a reaping section of a combine harvester in which a rod is extended from the side of the other raking wheel, the support frame of the raking rod is supported from above by a support frame extending from the upper end side of the central support shaft of the raking wheel. Since they are arranged in series to support them, there is no support part below to support the levers as in the past, so weeds, soil, etc. do not accumulate on the lower side as in the past. Grain culm transportation is carried out smoothly, the gripping rod has a structure that is more robust than the support shaft side so that it can be supported well, and it has the advantage that it can be carried out suitably with a simple structure.
