Field of the Invention The present invention relates to a main transport device for feeding a cut culm from one of the left and right ends of a pre-cutting unit to a feed chain side of a threshing device, and a transport route of the main transport device. A sub-transport device for joining the harvested culm from the other end of the left and right ends of the pre-cutting unit with respect to the intermediate position, and cutting the main transport device between the endless rotating chain and the clamping rail. A combine transport mechanism that clamps and feeds the stem of the grain culm and a transport mechanism that locks and sends the tip of the harvested grain culm with a number of locking members provided on the endless rotating band. More specifically, the present invention relates to a technology that allows an increase in the volume of a harvested grain culm conveyed between an endless rotating chain and a holding rail.

[0002]

2. Description of the Related Art As described above, as a technique for allowing an increase in the volume of cut culms transported between an endless rotating chain and a holding rail, a transport system having a different configuration from the above-described configuration is used. Japanese Unexamined Patent Publication No. Hei 7-16016 discloses a conventional example in which the transport chain is displaced away from the guide body, that is, displaced to the side where the chain is loosened, so that the volume of the cut culm can be increased. It is configured.

[0003]

Here, in consideration of the mode of transport of the harvested grain culm in the combine transporting device, the main transporting device is provided as described above, and the main transporting device is positioned at an intermediate position on the transporting path. In the configuration where the harvested culm from the sub-transporter is joined, if the harvested culm increases, the volume of the harvested culm at this confluence also increases rapidly, and clogging is likely to occur. There is room for improvement. The object of the present invention is such that the harvested grain culm from the sub-transport device is merged with the main transport device in this way, and a rationally configured grain culm transport device that is unlikely to cause clogging at this junction is formed. On the point.

[0004]

According to a first aspect of the present invention, a first aspect of the present invention is a feed chain of a threshing apparatus for cutting culms from one of the right and left ends of a pre-cutting unit. And a sub-transport device that joins the harvested grain culm from the left and right other end side of the pre-cutting processing unit to an intermediate position of the transport path of the main transport device, and A pinch transport mechanism that clamps and feeds the stem of the harvested grain culm between the endless rotating chain and the gripping rail, and a number of locking members provided in the endless rotating band, the tip of the harvested grain culm. In a combine grain conveying device configured with a locking and conveying mechanism that locks and feeds, a support rail is disposed on the side opposite to the clamping rail of the endless chain of the clamping and conveying mechanism, and The support rail can be approached and separated from the clamping rail Movably supporting and lies in that it includes a biasing mechanism for biasing the support rail on the side of the clamping rail, its action and effects are as follows.

[0005] A second feature of the present invention (claim 2) is that, in claim 1, the support rail is disposed at a position where the grain stem from the sub-transport device joins. And the effect is as follows.

A third feature of the present invention (claim 3) is that in claim 1 or 2, the front end of the support rail is swingably supported around an axis perpendicular to the winding surface of the endless rotating chain. And at the rear end position of the support rail, a position is formed at which a biasing force of the biasing mechanism is applied.
The operation and effect are as follows.

[0007] A fourth feature of the present invention (claim 4) is that, in claim 1 or 2, the support rail is supported via a support mechanism that allows a parallel movement in a direction along a winding plane of the endless rotating chain. The operation and effect are as follows.

According to the first feature, the harvested cereal culm conveyed by the main transport device is brought into contact with the harvested grain culm from the sub-transport device at an intermediate position of the transport path of the main transport device. Even if the transport amount increases, the support rail is displaced to the side away from the clamping rail by the action of the pressure from the harvested grain culm, and the displacement of the endless rotating band is also allowed with this displacement, so the harvested grain culm is Even if the harvesting culm of the volume exceeds the holding capacity of the holding rail due to the expansion of the conveying path on the stock side, clogging does not occur.

According to the second feature, when the harvested grain culm is fed from the sub-transport device, the support rail at a portion where the volume of the harvested grain culm rapidly increases is displaced in a direction away from the clamping rail. By configuring to
The endless rotation band is allowed to be displaced at this portion, which does not lead to clogging.

According to the third feature, the support rail is displaced to the side separated from the holding rail by the swing, and the swing can be largely swung toward the lower side of the transport, so that the displacement of the endless rotating band on the lower side of the transport is allowed. The harvested culm can be fed smoothly to prevent clogging.

According to the fourth feature, since the support rail can be moved in a form in which the support rail moves parallel to the side away from the sandwiching rail, even if the volume of the cut cereal culm increases, the entire conveyance path can be moved by the displacement of the endless rotating band. Smoothly feeds a large volume of grain stalks and does not lead to clogging.

[Effects of the Invention] Therefore, even in a configuration in which the harvested grain culm from the sub-transport device is merged with the main transport device, the transport route on the stock side of the main transport device is enlarged so that the harvested grain culm can be removed. The grain culm transport device that is unlikely to cause clogging was rationally configured (claim 1). Further, even if the volume of the harvested grain culm rapidly increases at the junction of the main transport device and the sub-transport device, clogging of the harvested grain culm does not occur (claim 2), and the delivery of the harvested grain culm can be smoothly performed. By doing so, clogging of the harvested grain culm does not occur (claim 3), and clogging of the harvested grain culm can be caused by an average expansion of the transport path in response to an increase in the volume of the harvested grain culm. (Claim 4).

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a raising device 1 provided with a large number of locking claws 1a for causing a cereal culm in a field, and a projection member for locking the root of the cereal culm from the raising device 1 and sending it backward.

It is also possible to support. With this configuration, when the support rails 12 are displaced, the entire transport path is enlarged, and the transport of the cut stalks is facilitated, so that stagnation and clogging hardly occur.
