Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain culm reaping guide device that can be used in reaping devices such as combines and binders, and simplifies the installation of a rake rotor that guides the rake to the cutting blade device. This aims to eliminate obstacles such as mud puddles and straw puddles during reaping work.

For this reason, the present invention has taken the following technical measures. That is, it spans between the reaping transmission case 2 to which the reaping blade device 1 for reaping grain culms is attached in conjunction with the reaping transmission case 2 and the weeding rod 3 that protrudes forward from the reaping transmission case 2, and the area in front of the reaping blade device 1. A raking rotating body 4 which is located at
The grain culm reaping guide device is configured by connecting a shaft support frame 6 that detours around the front side of the grain culm reaping guide device.

With this configuration, the present invention has the following technical effects. That is, during reaping work, as the machine moves forward, the grain culms that have been split by the weeding rod 3 are raked and guided rearward by the raking rotary body 4, and the base of the stock is moved by the cutting blade device 1. The shaft support 5 of the raking rotary body 4 is located in front of the cutting blade device 1 and is connected between the cutting transmission case 2 and the weeding rod 3. Since the shaft support frame 6 is located on the rear inner side of the shaft support frame 6 that connects the two parts, and the shaft support frame 6 bypasses the front side of the shaft support 5 part, it is Even if the stock part of the grain culm that is being scraped into sliding contact, this straw waste, mud, etc. is unlikely to come into direct contact with the shaft support 5, and is guided rearward by the shaft support frame 6. Such mud puddles and straw puddles can be reduced, and the rigidity of the reaping transmission case 2 and the grass dividing rod 3 can be increased, and the raking rotary body 4 can be provided with a stable shaft support structure.

In the illustrated example, the reaping transmission case 2 is integrated with the front end of the reaping machine frame 7 which protrudes forward from the traveling vehicle body and is movable up and down in the horizontal direction. A reciprocating type cutting blade device 1 is provided and configured to be driven by an interlocking device in a cutting blade transmission case 2.
The weeding rod 3 is integrally provided so as to protrude forward from the cutting blade transmission case 2, and the raking rotary body 4 is formed in a starfoil shape and is located inside the weeding rod 3 at both left and right ends. , is attached to a rod-shaped shaft support frame 6 that connects this dividing rod 3 and the cutting blade transmission case 2, and the lower end of this shaft support 5 is located inside the curved shaft support frame 6. The scraping rotor 4 is rotatably mounted on the shaft support 5. Further, the raking rotary body 4 is integrally provided with a sprocket 8, a pulley 9, etc., and a grain culm raking chain is installed between the sprocket 8 and a sprocket 10 provided above the rear cutting blade transmission case 2. 11, and the pulley 14 is passed between the pulley 9 and the pulley 13, which is supported on the front end of the guide frame 12 which protrudes forward from the upper end of the shaft support 5. The structure is such that the chain 11, the scraping rotary body 4, the belt 14, etc. are rotated in conjunction with each other by rotation. Reference numeral 15 denotes a raking rotary body provided at the left and right center portions, which is directly pivoted and interlocked with a bracket 16 protruding forward from the cutting blade transmission case 2, and a raking chain 17 is stretched over the upper side. There is. 18 is a guide rod placed along this scraping chain 17. Further, a grain culm lifting device is provided upwardly and forwardly from the reaping transmission case 2.

Reference numeral 19 denotes a grain culm supply port 2 of the threshing device 20 located above the rear end confluence of the scraping chains 11 and 17 and located at the upper part of the rear vehicle body.
With the grain transfer device stretched towards 1, the clamping rod 22
It is possible to transfer the harvested grain culm between the two.
Moreover, an endless body 23 for feeding the ears is provided on the upper side thereof. 24 is a stock transfer chain of the threshing device.

When the combine harvester configured in this way is moved forward to perform reaping, the interlocking mechanism in the reaping transmission case 2 moves the mowing blade device 1, the rake rotary body 4, and 15.
When the culm etc. are rotated in conjunction with each other, the grain culm placed in the dividing rod 3 by the movement of the machine body is pulled up by the grain culm lifting device, guided by the rotating raking belt 14, and then raked. It is scraped in by the rotary body 4, and the scraping chain 1
1 and 17, while the stock is being scraped to the rear, the root part of the grain is cut off by the cutting blade device 1, the culm of the grain is transferred by the transfer device 19, and the tip part is cut into an endless one. The grains are engaged and transferred by the body 23, and then transferred and supplied to the grain supply port 21 of the threshing device 20 for threshing processing.

Although the shaft support frame 6 is located relatively at the bottom, the shaft support 5
Since the front side is located and fixed to the rear side of the shaft support frame 6, the front side has a smooth surface and hardly gets caught by straw debris or mud. Moreover, although the grain culm is raked and guided from the front side to the rear side by the raking belt 14, the raking rotating body 4, the raking chain 11, etc. This prevents intervention on the side of the shaft support 5 because the shaft is guided backward.

Claims (1)

[Claims] 1. In front of the cutting blade device 1, it spans between a reaping transmission case 2 to which the cutting blade device 1 for reaping grain culms is attached in conjunction with the cutting blade device 1, and a weeding rod 3 that projects forward from the cutting transmission case 2. This grain culm reaping guide device comprises a raking rotary body 4 which is positioned and guides the grain culm by a shaft support 5, and a shaft support frame 6 which detours around the front side of this shaft support 5.
