Description

[Detailed description of the invention] Conventionally, as a weed splitting device for a harvester, a pair of upper and lower diamond-shaped guide bodies was provided at the rear of an intermediate weed splitting body between a pair of grain culm pulling bodies, and conveyor belts with lugs were provided on the left and right sides of the guide bodies. A conveyor belt is already known in which the tips of the lugs enter the gaps between the upper and lower guide members to prevent culm leakage.

However, the tip of the lug of the conveyor belt may catch the grain culm and push it in, and at that time the grain culm bends, causing the ear to become lower by H as shown in Figure 7. When the grain culm is fed to the threshing device, there is a drawback that unhandled grain is left untreated.

In addition, at the start or end of harvesting or when the amount of harvested grain culms is small, there have been drawbacks such as grain culms slipping off or culm leakage occurring when being transferred to the next conveyance belt.

The present invention is an attempt to improve the above-mentioned drawbacks, and is to provide an intermediate grass cutting body in the middle part of a pair of grain culm pulling bodies, and a cutting blade, a pair of raking wheels, and a flexible lug at the rear and lower part. In a harvesting machine which is equipped with an attached conveyor belt so that grain culms raked from the left and right are transferred to the next conveyor belt, a guide rod is provided protruding from the rear part of the intermediate weeding body toward the raking wheel, and the A guide plate having a vertical width with an intermediate portion bulging left and right is provided at the upper part, and the rear outer surface of the guide plate is brought close to the conveyor belt to such an extent that the tips of the lugs abut and bend. It is characterized by:

The embodiment shown in the drawings will be explained below.1
is a grass cutting body provided on both sides of the front part of the pre-processing section of the combine, and at the rear thereof, a pair of left and right grain culm pulling bodies 2, 2 are provided, and an intermediate grass cutting body 3 is arranged in between. .

Reference numeral 4 denotes a cutting blade attached to weeding frames 5, 5, and a pair of left and right vertical shafts 6, 6 supported on the upper part have raking wheels 7, 7 attached to the lower part, respectively, and a V pulley attached to the upper part. A large number of flexible lugs 9' are provided between the V-pulleys 8' and 8' on the front and outer side thereof.
A sprocket 10 attached to the middle part of the vertical shaft 6 on the left side when viewed from the front is used to direct the grain culms toward the threshing device at the rear. The front part of the grain conveying chain 11 that conveys the grain is wrapped around it.

and an intermediate grass frame 3a of the intermediate grass body 3;
The front part of the guide rod 12 is welded to the front part of the guide rod 12, which is approximately diamond-shaped and whose rear part approaches the rotation locus of the scraping wheels 7, 7. The front part of a guide plate 13 which is bulged and has a substantially rhombic shape in plan view and has a vertical width is welded, and the guide surface of the rear part of the guide plate 13 is connected to the flexible lug 9'.
... is close enough to the conveyor belts 9, 9 to bend when pressed.

Next, to explain the operation, the two-row grain culm is separated by the left and right cropping bodies 1, 1 and the middle cropping body 3, and then pulled up by the grain culm pulling bodies 2, 2, and then by the guide rod 12 and the guide plate 13. The grass is divided to the left and right by the
... scrapes the grain culm, and when the grain culm reaches the protrusion of the guide rod 12 and the guide plate 13, the guide rod 12 pushes the grain culm into the valley between the protrusions of the raking wheels 7, 7, so that the grain culm is raked. The rings 7, 7 scrape the stock base, and the lugs 9' of the conveyor belts 9, 9 press their tips against the plate surface of the guide plate 13 and bend, locking the grain culms and scraping the stems. included,
The cutting blade 4 cuts the root part of the grain culm.

This harvested grain culm is further raked in by the lugs 9' of the conveyor belt 9, and when the lugs 9' separate from the guide plate 13 at the rear rotating section, the lugs 9' rapidly expand and return to their original shape. Since the grain culm rotates while moving, the locked grain culm is thrown toward the rear grain culm conveyance chain 11, and is then held and conveyed rearward by the grain culm conveyance chain 11 and the clamping rail 14.

The guide plate 13 has a vertical guide surface pressed by a lug 9', and its upper and lower edges are bent inward to form a U-shaped cross section as shown in FIGS. 2 and 3. It does not bend because it is

As mentioned above, the present invention provides an intermediate grass cutting body in the middle part of a pair of grain culm pulling bodies, and a cutting blade, a pair of raking wheels, and a conveyor belt with flexible lugs are provided at the lower rear of the intermediate part, and raking from the left and right sides is provided. In a harvesting machine that transfers the packed grain culms to the next conveying belt, a guide rod is provided protruding from the rear of the intermediate tiller body toward the raking wheel, and an intermediate portion of the upper part of the rod protrudes from the left and right. A guide plate having a vertical width and a vertical width is provided, and the rear outer surface of the guide plate is brought close to the conveyor belt to such an extent that the tip of the lug abuts and bends, so that the lug of the conveyor belt is close to the plate of the guide plate. It is pressed against the surface so as to flex, and the grain culm retained on the lug does not fall off.

Moreover, since the lugs move while being supported by the guide plates, there is no need to bend the grain culms and lower the ears, unlike in the known method, and there is no possibility of unhandled grains being left behind.

Furthermore, the lugs of the conveying belt rotate while stretching all at once at the end of its movement by the amount that they had been bent during transport, so the caught stalks are thrown toward the next conveying belt.This means that the stalks can be successively conveyed in an orderly manner without falling out, dropping out, or becoming distorted, not only during continuous harvesting, but also at the start and end of harvesting or when there is a small amount of stalks.
