Description

[Detailed description of the invention] The present invention has a part of a series of conveyance paths as a locked conveyance part.
Further, the first stem culm conveying device in which the other portion including the end portion of the path is constituted as a clamping conveying portion, and the to-be-transported stem culm being conveyed by the locking conveying portion of this first stem culm conveying device, and a second stem culm conveying device that pinches and conveys the stem culm, and when viewed in the culm length direction of the conveyed stem culm, the conveying path of the second stem culm conveying device is arranged such that the conveying path of the second stem culm conveying device is on the lower side of the conveying side with respect to the conveying path of the first stem culm conveying device. , the second
The present invention relates to a stem culm conveying device that is configured so that the stem culm can be pulled out in the culm length direction during locked conveyance.

In the above-mentioned stem culm conveying device, when the stem culm to be conveyed is pulled out from the first stem culm conveying device, the stem culm is combed with the protruding pawl provided on the conveying chain of the first stem culm conveying device. There was a risk that the stem culm would be severed due to straining and the resistance to pull out increased.

In order to eliminate this drawback, a locking guide rail of the first stem culm conveying device is provided at a position shifted from the conveying chain on the side opposite to the pulling direction in the culm length direction of the conveyed stem culm, and performing a pulling operation by shifting the position of the second stem culm conveying device with respect to the first stem culm conveying device in the direction toward the tip of the protruding claw, so that the stem culm is located at the tip of the protruding claw at the time of pulling out, It has been considered to reduce combing resistance.

However, in such a structure, when the stem culm is pinched and conveyed by the first stem culm conveying device after the pulling action, the stem culm is largely misaligned in the lateral direction of the culm length with respect to between the conveying chain and the clamping rail. When the stem culm enters between the clamping rail and the conveying chain, the continuously fed stem culm moves in the lateral direction of conveyance,
During this time, the stem culms stagnate, causing clogging during transportation.

It is an object of the present invention to provide a stem culm conveying device that eliminates these drawbacks and can perform smooth pulling and conveying operations.

The present invention is the above-described stem culm conveying device, in which the first stem culm conveying device is placed on the side closer to the second stem culm conveying device of both link plates located apart in the culm length direction of the conveyed stem culm. The sliding resistance of the link plate that contacts the stem culm on the side far from the second stem culm loading position is smaller than the sliding resistance of the link plate that contacts the stem culm in the culm length direction. , a conveyor chain forming sliding contact surfaces of both link plates, and a conveyor chain that faces the conveyor chain at an intermediate position of both link plates in the culm length direction, and is located on the upper side in the stem culm conveyance direction. , and a clamping rail that continuously clamps and guides the stem culm following the clamping guide rail at a position downstream from the clamping guide rail in the transport direction. shall be.

In other words, the part of the stem culm that is to be held between the transport chain and the clamping rail, which faces the middle part of the transport chain, is held by the locking guide rail so as not to be separated from the transport chain by more than a certain level even during the locking and transporting process. Since the stem culm does not move significantly in the lateral direction of conveyance when moving from locked conveyance to clamped conveyance, it is possible to convey smoothly without any stagnation during conveyance, and the first and second stem culms can be conveyed easily. Since the device acts to pull out the stem culm at an angle with respect to the conveyance path of the first stem culm conveyance device, the link plate of the conveyance chain of the first stem culm conveyance device is closer to the second stem culm conveyance device. ) The stem culm is pressed more strongly against the link plate on the opposite side during the pulling operation, but the link plate at this point is not pressed against the link plate on the side closer to the second stem culm conveying device. ) so that the sliding contact resistance in the culm length direction of the far side link plate Ki is smaller than the sliding contact resistance in the culm length direction of K.
Since the sliding contact surfaces of both link plates are formed, there is no combing resistance as a whole, or there is little combing resistance.
Now it can be pulled out smoothly.

Next, embodiments of the present invention will be described in detail based on the drawings.

Figures 1 and 2 show a combine harvester.
