The present invention relates to a combine comprising a cutting device, an auger, and a feeder.

As the above-mentioned combine, for example, the combine described in Patent Document 1 is already known. This combine is provided with a reel (“rotary reel” in Patent Document 1) for scraping a planted grain culm. Further, the cut grain culm cut by the cutting device (“cutting blade” in Patent Document 1) is accepted in the cutting frame.

Then, the cut grain culm in the cutting frame is conveyed in the left-right direction of the machine by an auger (“horizontal feed auger” in Patent Document 1), and is scraped to the rear of the machine. The harvested culm squeezed by this auger is transported to the rear of the machine by a feeder.

Japanese Unexamined Patent Publication No. 2016-178866

Here, when the combine harvester described in Patent Document 1 is used for harvesting wheat, when the combine is run at high speed, the harvested culms are densely packed in the harvesting frame in a standing state, so that the auger harvests the harvested culms. It may be difficult to scrape. It is considered that this is mainly because the wheat culms are relatively hard and the cut culms tend to be densely packed in the cutting frame due to high speed running.

Then, when it becomes difficult for the auger to scrape the cut grain culm, the cut grain culm becomes clogged in the cutting frame.

An object of the present invention is to provide a combine that can easily avoid a situation in which a harvested grain culm is clogged in a harvesting frame.

The features of the present invention are a reel that scrapes the planted culm while rotationally driving around the reel axis along the left-right direction of the machine, a cutting device that cuts the planted culm, and a cut grain cut by the cutting device. After the cutting frame that accepts the culm, the auger that transports the cut grain culm in the cutting frame in the left and right direction of the machine while rotating around the auger axis along the left and right direction of the machine, and scrapes it to the rear of the machine. It is provided with a feeder which is connected to the wall portion and transports the cut grain culm squeezed by the auger to the rear of the machine, and is rearward of the cutting device at the lower part in the cutting frame. , the position is forward of the auger, e Bei the reaper grain稈倒with members provided in a state extending in the horizontal direction of the machine body, a gap for communicating the region near region and the auger near the cutting device back and forth The cut grain culm member is provided at a position higher than the bottom surface of the cutting frame so as to be formed between the cut grain culm member and the bottom surface portion of the cutting frame.

In the present invention, the cut grain culm cut by the cutting device is knocked down by the cut grain culm cutting member. Then, the fallen harvested culm is smoothly scraped to the rear of the machine by the auger.

This makes it less likely that the harvested culms will be crowded in a standing position. Therefore, according to the present invention, it is easy to avoid the situation where the cut grain culm is clogged in the cutting frame.

Further, in the present invention, it is preferable that the harvested grain culm member is arranged at a position higher than the upper end of the cutting device and lower than the auger shaft core.

When the cut grain culm member is located lower than the upper end of the cutting device, the cut grain culm member is less likely to come into contact with the cut grain culm. This makes it difficult for the cut grain culm member to knock down the cut grain culm.

Here, according to the above configuration, the cut grain culm cutting member is arranged at a position higher than the upper end of the cutting device. Therefore, the cut grain culm member is likely to knock down the cut grain culm.

Further, the higher the position where the cut grain culm member is arranged, the greater the resistance that the combine receives from the planted grain culm and the cut grain culm.

Here, according to the above configuration, the cut grain culm cutting member is arranged at a position lower than the auger shaft core. Therefore, the resistance that the combine receives from the planted grain culm and the cut grain culm is smaller than that in the case where the harvested grain culm member is arranged at a position higher than the auger shaft core.

That is, according to the above configuration, it is possible to realize a configuration in which the cut grain culm member easily knocks down the cut grain culm, but the resistance received by the combine from the planted culm and the harvested culm is relatively small.

Further, in the present invention, it is preferable that the distance between the cut grain culm member and the cutting device is shorter than the distance between the cut grain culm member and the auger in a plan view.

If the distance between the harvested grain culm and the auger is relatively short, it is assumed that the harvested culm affected by the harvested grain culm reaches the auger before it has fully collapsed. In that case, the auger is less likely to scrape the harvested culm.

Here, according to the above configuration, the distance between the cut grain culm cutting member and the auger becomes relatively long. Therefore, the cut grain culm affected by the action of the cut grain culm reaches the auger in a sufficiently collapsed state. As a result, the auger can smoothly scrape the harvested culm to the rear of the machine.

Further, in the present invention, the cutting device has a fixed blade and a movable blade that reciprocates in the left-right direction of the machine with respect to the fixed blade, while reciprocating in the left-right direction of the machine together with the movable blade. A lateral feed member for transporting the harvested grain in the left-right direction of the machine is provided, and the harvested grain tilting member is arranged on the rear side of the lateral feed member and at a position lower than the upper end of the lateral feed member. It is preferable to have.

When the cut grain culm member is arranged in front of the lateral feed member, the cut grain culm is guided upward by the cut grain culm member, and the cut grain culm passes above the lateral feed member. Is assumed. When the cut grain culm passes above the lateral feed member, the lateral feed member cannot transport the cut grain culm in the left-right direction of the machine body.

Here, according to the above configuration, the cut grain culm cutting member is arranged on the rear side of the lateral feed member. Therefore, it is possible to avoid a situation in which the cut grain culm is guided upward by the cut grain culm member so that the cut grain culm passes above the lateral feed member. As a result, the lateral feed member can reliably transport the cut grain culm in the left-right direction of the machine body.

Further, the higher the position where the cut grain culm member is arranged, the greater the resistance that the combine receives from the planted grain culm and the cut grain culm.

Here, according to the above configuration, the cut grain culm cutting member is arranged at a position lower than the upper end of the lateral feed member. Therefore, the resistance that the combine receives from the planted grain culm and the cut grain culm is smaller than that in the case where the harvested grain culm is arranged at a position higher than the upper end of the lateral feed member.

That is, according to the above configuration, the lateral feed member can reliably transport the harvested culm in the left-right direction of the machine, and the combine receives relatively little resistance from the planted culm and the harvested culm. can.

Further, in the present invention, the feeder is arranged at a position deviated to one side in the left-right direction of the machine with respect to the center position of the cutting frame in the left-right direction of the machine, and the cut grain defeating member is the cut frame. It is preferable that the cutting frame is provided from the other end of the cutting frame in the left-right direction of the machine to the center position in the left-right direction of the machine.

In the cutting frame, the farther away from the feeder in the left-right direction of the machine, the easier it is for the cut grain culm to stay. Therefore, when the feeder is placed at a position deviated to one side in the left / right direction of the machine with respect to the center position in the left / right direction of the cutting frame, the other side in the left / right direction of the machine in the cutting frame is left / right in the cutting frame. Compared to one side in the direction, the harvested grain is more likely to stay.

Here, according to the above configuration, the cut grain culm cutting member is provided from the other end of the cutting frame in the left-right direction of the machine to the center position of the cutting frame in the left-right direction of the machine. As a result, at least on the other side of the cutting frame in the left-right direction of the machine, the cutting grain culm can be reliably knocked down.

As a result, it becomes easy to prevent the culm from staying on the other side in the left-right direction of the machine in the cutting frame. As a result, it is possible to effectively prevent the retention of the cut grain culm in the cutting frame.

Further, in the present invention, it is preferable that the cut grain culm member is provided so as to extend over the left and right ends of the cut frame.

According to this configuration, the cut grain culm can be reliably knocked down over the left and right ends in the cutting frame. As a result, it is possible to more reliably avoid the situation where the cut grain culm is clogged in the cutting frame.

Further, in the present invention, it is preferable that the cut grain culm cutting member has a rod shape and is supported by the left end wall and the right end wall of the cutting frame.

According to this configuration, it is possible to provide a cut grain culm cutting member with a relatively simple configuration. Moreover, according to this configuration, it is not necessary to newly provide a member for supporting the cut grain culm cutting member. Therefore, an increase in manufacturing cost can be suppressed.
