Description

[Detailed description of the invention] (Industrial application field) This invention harvests the crops to be planted in the pre-treatment section.
This invention relates to a stem culm scraping roller in a harvesting machine that feeds harvested stem culms as they are to a cutting machine and shreds them, and that can suitably scrape the harvested stem culms into the cutting machine regardless of the posture of the harvested stem culms. It is.

(Prior Art) There is a harvesting machine that reaps a crop to be planted in a pre-processing section, and directly supplies the cut stem culm (cut stem culm) to a stem culm supply port of a cutting machine in a conveying section to shred it.

In this type of harvester, when feeding the reaped stem culm to the cutter roller attached to the stem culm supply port of the cutting machine, the reaped stem culm may be cut in the horizontal or diagonal direction due to various cutting conditions in the pre-processing section. Since the culms are mixed together and fed to the cutter roller, the culm posture of the reaped culms cannot be maintained in a fixed direction, and the smooth feeding of the cutter roller to the rotating blade is obstructed, and especially long culms become horizontal and cut. When conveyed to the stem culm supply port of the machine, the stem culm supply port is caught at both ends of the frame in a horizontal structure, making it difficult to cut into the cutter roller.

(Purpose) Therefore, the present invention was made in view of the above-mentioned problems, and by providing a scraping roller, even if the culm posture of the reaped culm changes, the reaped culm can be suitably transferred to the cutter roller of the cutting machine. It is an object of the present invention to provide a stalk culm raking roller in a harvester that can be fed.

(Structure) That is, the feature of the stem culm scraping roller in the harvester according to the present invention is that a conveying section is provided behind the pre-processing section, and the conveying end of the conveying section is placed in front of the stem culm supply port of the cutting machine. In the harvester configured to face the stem, a scraping roller located in front of the cutter roller is provided at the most forward part of the stem culm supply port, and the width of the scraping roller is made wider than the width of the cutter roller. be.

(Effects) In other words, in this invention, by providing the scraping roller in front of the cutting machine, the harvested stem culm that has been conveyed to the stem culm supply port of the cutting machine is scraped by the scraping roller and transferred to the cutter roller. Even if the culm posture changes widely during raking, it has the advantage of being able to rak properly.Also, by making the width of the raking roller wider than the width of the cutter roller, the cutting machine In addition to making it easier to scrape in the reaped stem culms that are transported horizontally to the stem culm supply port, the width of the frame that forms the stem culm supply port is widened, and the frame is sometimes locked horizontally to the frame. The long culm to be cut can be easily bent by the fingers attached to the cutter roller, and therefore the scraping resistance acting on the finger rollers can be reduced. Since the width of the raking roller can be increased regardless of the width of the cutter roller, in order to improve the raking performance, even if the width of the raking roller is increased, the width of the cutter roller can be limited to below a predetermined width. On the other hand, as the width of the cutter roller becomes narrower,
As the length of the rotary blade becomes shorter, the diameter of the cutter wheel to which the rotary blade is attached can be restricted to a smaller size.
This also has the advantage that the shape of the cutting machine body can be made smaller.

Furthermore, according to this invention, a culm receiving plate is provided below the conveyance terminal end of the conveyance section, and the conveyance terminal end is located at the center of the scraping roller.
The following effects will occur.

In other words, when the harvested stem culm is sent from the conveying section depending on the type of crop or its properties such as short culm or long culm, there are differences in the conveying posture, and if the harvested stem culm is not received properly at the bottom, the raking roller will Problems such as stagnation and clogging occur at the intake port, but this is properly handled by the culm receiving plate with the above configuration, and this culm receiving plate prevents the posture of the stem culm from being disturbed. This makes it easier to take in the stem culm from the conveyance terminal end.

Furthermore, in the past, when the reaped stem culm was a particularly short culm, there were inconveniences such as falling of the culm, but by providing the above-mentioned culm receiving plate, such inconveniences can be avoided. This can also be prevented.

(Embodiments) Specific embodiments of this invention will be described below with reference to the drawings.

Figures 1 and 2 show a harvester implementing the present invention, where 1 is a pre-processing section consisting of a pulling device 1a, a reaping device 1b, a cross-feeding device 1c, etc., and 2 is a section for conveying the reaped stem culms. It is a conveyance part, and upper conveyance body 3
