2. Description of the Related Art In the above-mentioned combine, conventionally, during harvesting of rice and wheat, the volume of cereal stalk flowing from a cutting section to a cereal culm transport section becomes relatively large due to the properties of cereal culm. The inner diameter of the tubular body and the grain stalk receiving port facing the delivery portion of the tubular body were formed relatively large so that clogging hardly occurred.

[0003]

[Problems to be Solved by the Invention] Conventionally, when harvesting soybeans, the amount of dust generated and the volume of flowing cereal stems are smaller than those of rice and wheat due to the nature of cereal stems. The opening of the grain stalk receiving opening in the tubular body is large, and the endless rotating belt-shaped carrier is agitated and moved by the dust for the rotation operation. Troubles leaking to the outside were likely to occur. An object of the present invention is to make it easy to prevent stalk clogging during harvesting of rice, wheat, etc., but also to avoid dust leakage during harvesting of soybeans.

[0004]

According to the present invention, there is provided a mowing device acting on a planted cereal culm, a delivery portion for carrying the cereal culm from the mowing device to a rear side of the machine, and a cutting device of the mowing culm from the mowing device. A tubular body having a harvesting unit having a transport device that transports the whole to the delivery unit, a tubular body that communicates the delivery unit with the grain culm receiving unit of the threshing device, and is rotationally driven inside the tubular body. Whole culm feeding type equipped with a cereal culm transporter with an endless rotating belt-shaped transporter that transports and supplies the whole harvested culm from the delivery unit along the inner bottom surface of the tubular body to the cereal culm receiving unit and supplies it In the grain culm transport unit structure of the combine, in the upper part of the tubular body, in the middle part of the return path formed between the upper surface of the tubular body and the upper side of the endless rotating belt-like transport body, on the grain culm receiving part side A guide surface that acts to regulate the return of dust to the By this guide surface, the dust on the return path is configured to cross the endless rotating belt-shaped carrier vertically and to be guided downward from the middle of the return path toward the grain culm transfer path side. It is assumed that.

[0005]

First, basically, the tubular body is formed such that the harvested culm does not easily enter or flow and is hardly clogged when harvesting rice or wheat. For this reason, even if the grain culm receiving port and the cross-sectional area of the tubular body become large, the dust generated in the grain culm transport unit also moves the upper part of the tubular body along the return path of the endless rotating belt-like carrier. Even if the dust flows to the receiving port side, the dust hits the guide surface with the return flow, is guided down by the guiding action to the grain stem transfer path side, and is lifted and transported by the transported grain stem by the endless rotating band-shaped body. Therefore, it is unlikely to leak out from the grain stalk receiving port to the outside.

Further, since the guide surface is provided in the middle of the return path of the carrier, the dust is guided so as to be short-circuited and supplied to the middle part of the grain culm transfer path by the carrier. For example, compared with the case where a guide surface is provided near the end of the return path of the carrier, that is, in the vicinity of the grain culm receiving port, dust leakage from the grain culm receiving port can be more effectively regulated or prevented. .

[0007]

[Effect of the Invention] As a result, when harvesting rice and wheat, it is possible to work so that clogging of the culm does not easily occur due to the large cereal culm receiving port. The guide action of the guide body that passes downward through the endless rotating belt-shaped carrier and the transport action of the transported cereal culm can prevent leakage from the cereal culm receiving port, thereby improving work efficiency and preventing the work environment from deteriorating. And a grain conveying section that can achieve both.

[0008]

As shown in FIG. 2, a cutting section A having a raising reel 1, a cutting apparatus 2 and the like, and a grain culm conveying section B having an endless rotating belt-shaped conveying body 3 and the like are combined with a threshing apparatus 4 as shown in FIG. Attached to the front of the crawler-type traveling body provided with the driving cabin 5 and the like, the cutting unit A and the cereal culm transporting unit B cause the planted cereal culm to be raised and cut, and the entire culled cereal culm is removed. It is configured to be conveyed to the rear of the machine and supplied to the threshing device 4 to cut various grain culms such as rice, wheat, soybeans, etc., and throw the entire cut culm from the root to the tip to the threshing unit. The whole culm input type combine is configured to thresh.

The mowing section A is constituted by a mowing section body 6
A pair of right and left weeding tools 7 and 7 are attached to the front of the plant so that weeds of the planting grain stalk can be cut and the non-cutting object can be cut.
The clipper-type cutting device 2 and the transport device 8 are provided between the left and right side wall portions 6a, 6a of the cutting unit body 6, and the culm to be cut from the weeder 7 is raised by the raising reel 1. The mowing grain culm from the mowing device 2 is supplied to the mowing device 2 while being raised, and the entire harvested culm from the mowing device 2 is conveyed by the conveying device 8 to the sending portion 9 behind the culm, and from the sending portion 9 to the rear side of the machine. To be carried out.

As shown in FIG. 2, the conveying device 8 is provided between a pair of helical plates 8a and 8b, which are separately provided at both ends of a single rotating drum and have helical directions opposite to each other. Conveying blade 8c and conveying rod 8 attached to the rotating drum

The cutting culm from the portion 8b and the cutting culm from the portion located immediately before the delivery unit 9 of the cutting device 2 are joined, and the conveying blade 8c and the conveying rod 8d scrape the lower portion of the rotating drum. Outgoing unit 9 through
It is configured to be transferred to.

As shown in FIG. 1, the grain culm transporting section B communicates with the sending section 9 and a grain culm receiving section 4a in a threshing section of the threshing device 4 to form a cylindrical culm transport path. Body 10
And the endless rotating belt-shaped transporting body 3, and a plurality of transport plates 3 a of the endless rotating belt-shaped transporting body 3 are formed in a cylindrical shape from a grain culm receiving port 10 a facing the delivery section 9 of the tubular body 10. The lower part of the body rises to the grain culm outlet 10c facing the grain culm receiving portion 4a of the cylindrical body 10, and the upper part of the cylindrical body receives the grain culm from the grain culm outlet 10c of the cylindrical body 10. Since the endless rotating belt-shaped transporting body 3 is configured to be rotationally driven so as to descend to the mouth 10a, the entire harvested grain culm from the delivery unit 9 of the cutting unit A is converted into an endless rotating belt-shaped.
