The stalk-cutting device 21 on the rear side is cut and trimmed to the field, and the entanglement between the stalks to be harvested and the uncut-side stalk is separated by the weeding body 6. (Each symbol is described in the publication.)

JP 2005-211043 A (paragraph [0012], FIG. 1 and FIG. 2) JP 2007-89464 A (paragraphs [0019], [0025], [0038] FIGS. 1 and 2)

In the conventional structure described in Patent Documents 1 and 2 described above, the stalks to be trimmed are subjected to the trimming work by correcting the posture by the scraping action by the scraping reel or the like. When tangling occurs between the stalks to be cut near the uncut side and the stalks on the uncut side, it is configured to forcibly unravel by pushing with a weeding implement or a weeding body. Has been.
For this reason, when the degree of entanglement, such as rapeseed, is strong, the entanglement must be loosened by the segregating action of the weeding tools, and it has been easy for threshing of the stalks and tearing of the entangled stems to occur. .

  The object of the present invention can be achieved in a state where it is easy to avoid threshing and tearing of the cutting stems to be cut and the non-cutting stems even in the case of stems with significant misalignment or entanglement. The purpose is to provide an ordinary combine.

The first aspect of the present invention is a cutting device that cuts a planted stalk, and a reel type scraper that performs a scraping operation on a planted stalk to be harvested by rotating a scraping tine at a position above the cutting device. In a normal combine that includes a device and a threshing device that throws the whole stalks cut by the reaping device into a handling room and performs threshing and selection processing,
The transport start end is located at a position located on the front side of the traveling machine body from the cutting device and at the laterally outer side of the traveling machine body from the cutting action area of the cutting device, and the transport terminal part is located near the lateral end of the cutting device. The planter side conveying device that feeds to the cutting device by locking and conveying the planting side of the planted stalk toward the inner side in the lateral direction of the traveling machine body,
A driveable forced weeding device for weeding the planted stalk into a cutting target and a non-cutting target by weeding the planted stalk into the tip side of the stocker side conveying device is provided.

According to the configuration of the first aspect of the present invention, if the stems to be harvested are in an aligned state, the stems are located in or near the harvesting area of the harvesting device, and the stems to be harvested are the reel type scraping device. In addition to being squeezed by the stalk, a forced weeding device is applied to the tip of the stalk and the entanglement between the stalk to be cut and the uncut stalk is loosened by forced weeding. Can do.
Even if the stems to be harvested are in an unaligned state, and the stems that are misaligned to the uncut side from the harvesting area of the harvesting device are mixed, Since the side transport device acts and the stock base side of the stem that is misaligned is transported by the stock base side transport device while moving toward the inside in the lateral direction of the traveling machine body, the stock source side by the stock source side transport device It is possible to easily loosen the entanglement between the stems that are displaced due to the inward movement and the stems on the uncut side. As the misaligned stalk is transported by the stocker-side transport device, the force distribution device acts on the tip side rather than the stocker-side transport device of the misaligned stem and is misaligned. The entanglement between the stalks on the uncut side and the stalks on the uncut side can be loosened by a forced weeding action by a forced weeding device. Since the misaligned stalk is supplied to the cutting device by the planter-side transport device, the misaligned stalk can hardly be cut off.

  Therefore, regardless of whether the stems are in an aligned state or in an unaligned state, the entanglement between the stalks to be harvested and the unsheared side stems, even in the case of stalks such as rapeseed, where entanglement is extremely likely to occur, While being able to loosen well, it is possible to suppress uncut residue of misaligned stalks, and to perform a harvesting operation with a good finish that hardly causes uncut residue while suppressing grain loss due to threshing and tearing.

  In the second aspect of the invention, the forced weeding device is supported in an inclined posture that is positioned on the laterally outer side of the traveling machine body as the traveling machine body is located on the upper side.

The longer the stem of the uncut side, the longer the slime, the more likely it is that it will fall into the inside of the aircraft after it has been weeded with the pedicle to be cut. Become.
According to the configuration of the second aspect of the invention, the longer the slimming of the uncut stalks, the more the tip side of the stalks subjected to the entanglement by the forced weeding device comes into contact with the upper end side of the forced weeding device. The forced weeding device presses the stems toward the lateral side of the traveling body. As a result, even when the stem stem is long, it is possible to prevent the fall of the uncut-side stem stem after the weeding into the traveling machine body.

  Therefore, it is easy to avoid a situation in which the stalk is entangled with the body part due to the uncut-side stalk falling to the body side.

  In the third aspect of the invention, the forced weeding device includes a pedicle cutting device having a cutting action area along the vertical direction of the traveling machine body.

  According to the configuration of the third aspect of the invention, the stalks to be cut and the stalks on the uncut side can be weeded by cutting with a stalk cutting device, so that it is not necessary to apply a strong pushing force to the stalks. The entanglement can be unraveled well while effectively preventing.

  Therefore, even when the stalks to be harvested and the stalks on the uncut side are markedly entangled, not only the entanglement can be loosened, but also grain loss due to weeding can be effectively avoided. Can be suppressed.

  In the fourth aspect of the present invention, the forced weeding device is configured to include a weeding rod that is directed upward and downward, and a weeding rod driving mechanism that swings and drives the weeding rod.

  According to the configuration of the fourth aspect of the invention, the stalks to be harvested and the unsheared stalks can be weeded by forcibly swinging the stalks with a weed stalk, so that a strong discriminating force acts on the stalks. The entanglement can be unraveled satisfactorily while effectively preventing degranulation.

  Therefore, even when the stalks to be harvested and the stalks on the uncut side are markedly entangled, not only the entanglement can be loosened, but also grain loss due to weeding can be effectively avoided. Can be suppressed.

A rotation locus T2 shown in FIG. 9 indicates the rotation locus of the upper end 31c of the weed pod 31.
As shown in FIGS. 8 and 9, the weed cage driving mechanism 80 constitutes a four-barrel rotating chain approximate linear interlocking mechanism, and drives the rotating body 84 with a driving force of constant speed rotation to The connecting link 81 is oscillated and driven by the rotating body 84 so that the traveling body horizontal axis 45a serving as the weeding rod connection point draws the rotation trajectory T1, and the driving force of the connecting link 81 is transmitted to the weeding rod 31.

  As shown in FIG. 10, the rotation trajectory T1 of the aircraft lateral axis 85a has a straight portion Tf corresponding to the traveling forward movement of the aircraft lateral axis 85a in the rotation trajectory T1. A portion Tr corresponding to the rearward movement of the vehicle body lateral axis 85a is a curved line protruding upward.

  As a result, the weed rod driving mechanism 80 moves the upper end 31c of the weed rod 31 in the longitudinal direction of the traveling vehicle and the vertical direction of the traveling vehicle by drawing the rotation trajectory T2 with the lower end side of the weed grass 31 being the fulcrum side. In addition, a portion of the rotation trajectory T2 corresponding to the forward movement of the weed rod upper end 31c is a straight line, and a portion of the rotation trajectory T2 corresponding to the backward movement of the weaving rod upper end 31c is corresponding to the movement. The weed culvert 31 is driven so as to have a curved line protruding upward from the traveling machine body.

  The distance by which the machine body lateral axis 85a and the weed ridge upper end 31c are moved backward is longer than the distance that the machine body is moved forward, and the rotating body 84 is driven at a constant speed. Accordingly, the weed rod driving mechanism 80 has a low moving speed in the forward direction of the vehicle body axis 85a and the upper end 31c of the weed rod, and the rear direction of the vehicle body axis 85a and the upper end 31c of the weed rod. The weed basket 31 is driven in a state in which the moving speed of is high.

  Therefore, in the forced weeding device 30, when the weed pod 31 moves from the weed action start position S (see FIG. 9) toward the front of the aircraft and acts on the planted stem pod, the weed shed 31 Rushes into the planting stem and the planting stem tends to become a large movement resistance against the weed pod 31. The planted stalk 31 is driven at a low speed by the grass shoot drive mechanism 80, and the planted stalk 31 is made to act on the planted stalk while it is difficult to generate a large vibration of the planted stalk cultivated plant. And weeds on the uncut side of the planted stem.

  In the forced weeding device 30, when the weed basket 31 moves rearward and returns to the weeding action start position S, the weed basket 31 moves backward with respect to the stem and the planted stem Since it is difficult to generate a large movement resistance against the weed pod 31 and it is difficult to generate vibration of the planted stem pod 31, weed the weed pod 31 so that it returns to the weeding action start position S at high speed. The herbage is driven in a state where it is driven at a high speed by the heel drive mechanism 80 and the frequency at which the weed pod 31 acts as a weed while the traveling body 1 moves a unit travel distance is a frequency adapted to the planted stem pod such as rapeseed. Weed the pods 31 to the planted stem pods.
