Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine straw discharge device that holds and conveys the discharged straw after threshing to the rear of the machine by a transfer chain.

[0002]

[Prior art]

 Conventionally, this type of discharged straw conveying device has been equipped with a drive mechanism for forcibly striking the discharged straw conveyed by the conveying chain and separating and collecting the grains stuck in the discharged straw. It is proposed that a grain collection device is installed in the middle of the transportation route.

[0003]

[Problems to be solved by the device]

 However, the stab grain collecting device equipped with the above-mentioned drive mechanism has a drawback that it is not only economical but not only complicated and large in size but also expensive. The object of the present invention has been made in view of the above circumstances, and is highly economical with a device for separating and collecting the grain stuck in the discharge straw conveyed by the discharge straw conveying device. The point is to realize with a simple structure.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the characteristic configuration of the combine straw discharge device according to the present invention is such that guide rods are provided on the tip side of the convey path of the discharge straw by the convey chain, upward and downward along the convey path. The upper guide rod and the lower guide rod are arranged in a holding manner in an intersecting posture along the rod center direction so that the tips are bent and deformed in a meandering shape as the discharged straw is conveyed. There is a point.

[0005]

[Action]

 The transport rod conveys the grain rod on the tip side of the discharged straw in a state of being sandwiched between the upper and lower guide rods. Is bent and deformed. For example, as shown in FIG. 3, when one upper guide rod 13 and two lower guide rods 14 sandwiching the guide rod 13 are used, the upper guide rod 13 is lowered as the carrier is conveyed. Since the guide rods 14 and 14 are mounted so as to be in an intersecting posture located below the other guide rod 14, the tips slidably guided by the guide rods 13 and 14 gradually meander, and due to this meandering deformation, the drainage straws are discharged. There is a difference in the bending of the stem-culm group, which causes a relative shift in the culm length direction, and at this time, the grains stuck between the discharged straw-culm groups separate and fall.

[0006]

[Effect of device]

 In this way, a device for separating and collecting the grains stuck in the discharged straw conveyed by the discharged straw conveying device can be realized with a simple and inexpensive structure that does not use a drive mechanism. .

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the threshing device in the combine has a handling cylinder 2 for threshing the grain culms that have been held and conveyed by the feed chain 1 in a sideways posture, and is mounted on the upper part of the handling cylinder 2. A catching net 3 for leaking down the threshed processed product is stretched downward, and the processed product leaked from the receiving net 3 and the processed product dropped from the dust-sending port 4 at the rear end of the receiving net 3 Is equipped with a sorting device 5 for swinging and sorting, and is roughly sorted with the first item collecting section 7 for collecting the first item sorted by the swinging sorting by the sorting device 5 and the wind sorting by the Karako 6. A second product recovery unit 8 for recovering the second product is arranged below the sorting device 5.

A waste straw transporting device 9 for receiving the waste straw S after threshing treatment from the feed chain 1 and transporting the waste straw S to the rear is arranged in a space on the rear side of the handling chamber 10 on which the handling barrel 2 is mounted. An exhaust straw shredding device 11 for shredding the exhaust straw S sandwiched and conveyed by the exhaust straw conveying device 9 is disposed below the rear end portion of the exhaust straw conveying device 9.

As shown in FIG. 1 and FIG. 2, the discharged straw conveying device 9 includes a conveying chain 12 that is driven by power from the handling cylinder 2, and a tip of a conveying path R of the discharged straw S by the conveying chain 12. The guide rods 13 and 14 are arranged on the side. The guide rods 13 and 14 are cantilevered upward and downward along the discharge straw transport path R, and the upper guide rod 13 and the lower guide rod 14 are used to convey the discharge straw S. It is attached to the side plate of the threshing device in an intersecting posture along the rod center so that the tips are bent and deformed in a meandering shape.

As shown in FIG. 3, since the upper guide rod 13 is attached to the lower guide rod 14 in such a manner that the upper guide rod 13 and the lower guide rod 14 are gradually positioned downward, the guide rods 13 and 14 are attached to each other. The tips of the exhausted straws S guided by sliding gradually bend in a meandering shape. At this time, the discharge straw S conveyed in layers has a difference in curvature between the inside and outside of the bend, and the stem-culm group relatively shifts in the culm length direction, whereby the stem-culm group is stuck between the stem-culm groups. The existing grains are separated and fall on the sorting device 5 along the upper cover 16a of the blower fan 16.

As shown in FIG. 4, if the protrusions 15 made of an elastic material such as rubber are attached to the guide rods 13 and 14 at regular intervals, the guide rods 13 and 14 move along the guide rods 13 and 14. An appropriate resistance is given to a part of the guided waste straw S, the waste straw stem culm group is subjected to a judgment action, and the separation of the stuck grain is further promoted. Further, the guide rods are not limited to the one upper guide rod 13 and the two lower guide rods 14, and needless to say, the number can be set arbitrarily.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
