A scraper part material 9 is fixed on a movable blade 3b of the reaper 3 and a scraper acting part 9a of the scraper part material 9 is extended in a state vertically approaching to the raking rotors 4 and the scraper acting part 9a is constructed to move from the rotation center side to the outer diameter side of the raking rotors 4 and to return accompanying to a transverse moving to the other side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gear-shaped scraping device that acts on the root side of a stem culm cut by a clipper-type shaving device to scrape and convey the stalk culm toward a vertical conveying device. The present invention relates to a combine harvester having a rotating body.

[0002]

2. Description of the Related Art Conventionally, like a combine disclosed in Japanese Utility Model Laid-Open No. 29224/1990, the stems that have been raised are mowed with a mowing device, and the mowing stems are acted on the roots of the stems to make a rear vertical movement. A scraping rotary member that is forcibly transferred to the conveying device is provided on the rear side of the raising device to form a cutting unit.

The scraping rotary member in this structure has a high stem culm density at the scraping rotary member portion in order to forcefully convey the cut stalks from the left and right while merging them. Therefore, the transported stems tend to be stagnant and clogged, and the stems are wound around the gear-shaped outer peripheral portion of the scraping rotor, which tends to hinder a good transport function.

Therefore, as shown in the above-mentioned publication, a guide rod for guiding the transfer route of the stems is provided in the rotating body portion so as to eliminate the winding of the stems.

[0005]

However, the stalk-carrying path of the scraping rotary member is usually located directly above the cutting device, and the frame member such as the support rod of the weeding tool is also complicated. , The stem end of the stem culm is in a state of being conveyed while contacting those members, and therefore there is a tendency that the stem stalk still tends to stagnate, and the stem culm is bent or fragmented near the plant base. , Even if there was a guide rod, it was easy to wind up and wind around the rotating body.

An object of the present invention is to devise so that stalks can be more favorably conveyed by allowing the stalks to be jointly conveyed without being wound around the rotating rotary member.

[0007]

Means for Solving the Problems [Structure] The characteristic structure of the present invention is that, in the harvesting part of the combine described at the beginning, the scraper member is fixed to the movable blade of the harvesting device, and the scraper acting part of the scraper member is also provided. To a state in which the scraping rotary member is vertically close to the scraping rotary member, and the scraper acting portion moves from the rotation center side of the scraping rotary member to the outer diameter along with the lateral movement of the movable blade to one side. It is configured to move toward one side and return along with the lateral movement to the other side. [Operation] That is, with the lateral movement of the movable blade to one side,
Since the scraper action portion of the scraper member moves from the rotation center side of the scraping rotary member toward the outer diameter side and returns along with the lateral movement to the other side, even if the stems are scraped, the scraper rotating member outer circumference Even if it is wound around, it will be scraped out immediately by the scraper member and eliminated.

[0008] Therefore, the winding phenomenon does not occur at the scraping rotary member portion, and the harvested stem culm can be transferred to the vertical transport device without being clogged even if the transported stem culm is slightly stagnant.

Further, in the above structure, since it is not necessary to newly provide a drive mechanism for the scraper member, the structure does not become complicated.

[Effects] Therefore, by the relatively simple modification of arranging the scraper member close to the scraping member,
By eliminating the stalk winding on the scraping rotary body, the cut stalks can be joined and conveyed more smoothly and satisfactorily.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of a combine provided with a mowing part A, 1 is a weeding tool, 2 is a raising device, 3 is a mowing device, 4 is a scraping rotary member, 5 is a vertical conveying device, 6 Is a feed chain, 12 is a threshing device, and 13 is a crawler traveling device.

As shown in FIG. 2, the reaping device 3 is a hair clipper type which acts by relative lateral sliding between the fixed blade 3a and the movable blade 3b, and the crank arm 7 and the movable blade 3b which reciprocally swing at a fulcrum P. And have a structure in which they are abuttingly interlocked by fitting at the fulcrum Q. A drive rod 8 that is continuously pushed and pulled by a drive system (not shown) is connected to the crank arm 7. As shown in FIG. 4, the crank arm 7 has a fulcrum Q.
A balance weight 7a is provided at the end portion on the opposite side to.

The scraping rotary member 4 has a substantially gear shape and is arranged at the rear of the pulling device 2. The left and right parts of the scraping rotating member 4 are interlocked to be driven, and the stalks cut by the cutting device 3 are interlocked. The cutting stem culm to the vertical conveyor device 5
It is configured to forcibly send to. Above the scraping rotary member 4, an auxiliary scraping / conveying device 21 that shares a drive shaft with the scraping rotary member 4 is provided. In addition, as shown in FIG. 3, guide rods 15 and 1 for guiding the transportation route of the stems and stems.
6 are separately extended from the weeding frame to the left and right scraping rotating bodies 4 side.

Then, as shown in FIG. 2, the movable blade 3b.
The rod-shaped scraper member 9 is fixed to one end thereof, and the scraper action portion 9a on the other end side of the scraper member 9 is extended so as to vertically approach the scraping rotary member 4 on the right side, and is movable. The scraper acting portion 9a moves from the rotation center side of the scraping rotor 4 toward the outer diameter side along with the lateral movement of the blade 3b toward one side, and returns along with the lateral movement toward the other side. It is configured to do. That is, FIG.
As shown in (a), the scraper action part 9a moves the stem culm wound around the tooth part 4g of the scraping rotor 4 in the forward direction and pushes it out, and as shown in FIG. Then, it returns to the original retracted position, and this series of operations is repeated. Therefore, even if the stems are scraped and wound around the outer circumference of the rotating body 4, they are immediately scraped out by the scraper member 9 and eliminated.

The vertical conveying device 5 is composed of a plant base holding and conveying mechanism 5A for nipping and conveying the plant stem side of the culm, and an ear tip locking and conveying mechanism 5B for locking and conveying the tip end side. is there.

Explaining the rear part of this combine, as shown in FIG. 5, a rotary drum 10 having spiral-shaped handle teeth 11 is arranged along a discharge straw chain 20, and the handle drum 14 is attached to the rotary drum 10. The driving force is transmitted through the bevel gear mechanism 17, and the rotary drum 10 is driven,
It is configured to collect the grain and carry the tips.

As shown in FIG. 6, the helical handle 1
To form No. 1, a large number of independent handling teeth 19 are provided on the tip side of the screw 18 in a state of protruding from the outer peripheral edge of the screw 18 and in a state of being juxtaposed in the longitudinal direction of the screw 18. Below the rotary drum 10, a recovery path R for guiding the recovered grains to the sorting section is formed.
