Description

[Detailed Description of the Invention] This invention relates to a scraping device for a combine harvester,
A raking recess is provided between the auger and the reaping section that is horizontally suspended between the frames protruding forward, and a raking rubber body is placed below the raking foil provided in the raking recess. An object of the present invention is to provide a raking device for a combine harvester, which is configured to eliminate head loss due to threshing by harvesting grains that are threshed during reaping.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, the configuration will be explained. Combine harvester (1)
A threshing section (4) and a sorting section (5) are installed at the rear of a frame (3) supported by left and right crawlers (2) (2), and a driver's cab (6) and an engine (not shown) are installed at the front right side. omission)
It is configured with the following. A reaping conveyance section (7) is protruded from the front part of the machine body (1) and can be raised and lowered. The kernel reaping conveyance section (7) has a bottom plate (9) between the left and right side plates (8).
) to constitute the reaping transport frame αΦ, and side plates (8) (
+3) A front support rod αυ and a rear support rod (b) are provided in the part that protrudes downward from the bottom plate (9), separated from each other in the front and back.
Long links (B) are pivoted to the left and right sides of the center of the front support rod αυ, and short links (6) are pivoted to the left and right of the center and both sides of the rear support rod (B). Then, the lower ends of the long links (13)... and the short links 0... are attached to the left and right partial plants (16) θ6) that protrude to the front end of the support rods (lη The long link 68)... and the short link a→... are pivoted at a distance shorter than the distance between the upper end pivot points of the rear short link (b)...

are connected via. The scraping foil (C) has a release edge (B) (B) formed on the outer periphery of its central F ram portion (01) (01) that has a receding angle with respect to clockwise rotation, and also has a diameter The ejection blades, which formed the rear ends (A) and (B), which were cut in the direction of A release layer having a release edge ←4←◆ and a rear end 0→(C) formed on the outer periphery of the drum part (Foundation) (C) with a receding angle with respect to counterclockwise rotation - 〇 o'clock, 09 - are provided at the rear end ell (a), (2)), and scratching rubber bodies ho (b) are provided in four parts) so as to come into sliding contact with the bottom surface. Then, attach the pair of scraping foils (C) and (C) to the left and right side covers (G) so that the width of the front end is narrow and the width of the rear end is wide.
A scraping passage HHt- is provided by covering with a central cover (A). An auger θυ that collects the grain culms in the center is installed horizontally behind the above-mentioned raking wheels (c) (c) (c) and nine wheels (c), and a culm conveyor (b) is installed behind the auger 00. , a bottom plate (9) facing this culm conveyor (b)
A grain conveying helical body (not shown) is drivably provided in a vertical groove (not shown) formed along the culm conveying body (b). ) is a reel, (goods) is a beader, (

-It is.

Next, the effect will be explained. When carrying out combine harvesting work by putting the Humbine into a bean field and running it, the reaping conveyance section (7) is supported by the cutting body 6-5) H, (161 (+6+), divides the culm into two rows, and carries the reel - ) scrapes the head of the culm, the cutting part QI) cuts the stock base, and the grain culm is separated from the head to the rear auger section 5 and the bottom plate (

(c) (c), (c) (c) ejection feathers (c) (c), (c) -'... are transferred to the rear, and then taken over by the shell culm carrier (b). , and is transported along the bottom plate (9) and carried into the threshing section (4) via the beader (goods). Then, as the head of the culm is scraped by the reel m), the stock base is cut off, and the grains that fall into the four parts) while being bitten by the auger ◇ are thrown into the scraping foil) (c). The grains are released backward by the raking rubber body in (c) and (c), and are transferred to the threshing section (4) by the grain conveying body. When the weeding body hits a resistive object such as a stone on the ridge where it moves, the weeding body (+9 (+6) (t*) In addition, as a structure in which the branching body θF, 1 (161Qr+lθ) comes into contact with the resistor and escapes, the branching body 0 (181 (16) Q# support rod (b)... Pivot with the support rod (
B) A structure in which the front left and right sides are supported by springs is conceivable.

In short, this invention forms a lower recess at the bottom between the auger and the reaping section, which is horizontally suspended between the left and right frames of the reaping and conveying section that protrudes forward of the machine body, and in these four sections, the vertical kettle shaft. At the same time as the provided scraping foil was measured, a scraping rubber body was provided on the underside of the scraping foil so that it was against the bottom surface of the above four parts, so that the stock base of the culm was cut off and the head was bitten by the auger. The grains that fall during the process are collected in the four parts mentioned above and are prevented from rolling down to the soil surface, and the collected grains can be transported backwards without being damaged by the raking rubber body.
