Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pair of left and right paths for merging and conveying harvested grain culms immediately after being pulled up by a plurality of pulling devices, and a threshing fence for transporting the merged harvested grain culms. The present invention relates to a combine harvester equipped with a vertical conveyance path for conveying toward an eed chain.

Conventionally, in this type of combine harvester, the combined conveyance path and the vertical conveyance path are each configured by separate conveyance devices, and the handling depth is adjusted by vertically swinging the vertical conveyance device that constitutes the vertical conveyance path. , by vertically displacing the conveyance start end side or the conveyance end side.

However, in order to avoid having to clamp the stock side more than necessary when the grain culm is large when sending and receiving the grain culm from the hoisting device, the merging conveyor device is equipped with an intermediate culm length. It is set to hold an object in an appropriate position,
As a result, it is necessary to displace the vertical conveyance device relative to the merging conveyance device, or the conveyance device on the feed chain side relative to the vertical conveyance device, so that it extends above and below the conveyance terminal side, and eventually Also, a gap was created between the two, and due to the handling depth adjustment, the conveying posture was disturbed when the grain culms were transferred.

In view of the above points, the present invention avoids the occurrence of disturbances in the grain culm conveying posture due to adjustment of the handling depth, and makes it possible to appropriately transfer grain culms from a lifting device to a merging conveyance device regardless of changes in the culm length of the grain culms. The object of the present invention is to enable the handling depth to be adjusted satisfactorily without deteriorating the conveying performance while the articles are held in a certain position. Next, embodiments of the present invention will be described in detail based on the drawings.

A pulling device 1 that pulls up the planted grain culms in the field, a reaping device 2 that reaps the raised grain culms, and a harvesting device 2 that joins the harvested grain culms and transports the merged grain culms to the rear of the machine while lying on its side. A conveying device 4 that changes its posture and delivers it to the threshing feed chain 3, and a grain culm device 5 that threshes the harvested grain culm while being held and conveyed by the feed chain 3, are sequentially equipped with a crawler traveling device 6, The combine harvester is connected to a traveling vehicle body provided with a control section 7, and is configured to continuously harvest and process the planted grain culms in the field as it travels.

The conveying device 4 is comprised of a first conveying device 9 consisting of one endless rotation band 8 extending from immediately after the lifting device 1 to the feed chain 3, and a midway point of the first conveying device 9. A second conveying device 10 for merging the grain culms is provided, and the first conveying device 9
By the transport start end side of and the second transport device 10,
A pair of left and right merging conveyance paths R ₁ , R ₁ are formed for merging and conveying the harvested grain culms from the plurality of lifting devices 1 . A vertical conveyance path _R2 is formed which is connected to _R1 .

The first and second conveyance stations 9 and 10 are integrally provided with stock side clamping conveyance devices 9a and 10a and ear side locking conveyance devices 9b and 10b arranged vertically, and, A gate-shaped frame 11 is constructed over the transport start end side of the first transport device 9 and the non-transport route side of the second transport device 10, with the grain culm passing between them.
is integrally connected to the first conveying device 9, and is configured to transmit power from the first conveying device 9 to the second conveying device 10 through a transmission shaft (not shown) therein. Further, a support frame 12 is connected to the horizontal frame portion of the gate-shaped frame 11, and to the support frame 12, both stock base side clamping and conveying devices 9a, 10a are attached.
At the same time as attaching the clamping rails 13 to each,
A locking pawl 14 for each of the tip side locking and conveying devices 9b and 10b...a guide 15 for guiding the transfer is attached.

The first conveying device 9 is provided so as to be able to swing up and down around a horizontal axis P on its conveying end side, and as the first conveying device 9 swings, the conveying starting ends of the first and second conveying devices 9 and 10 are raised. The apparatus is configured to integrally vertically displace the harvested grain culm from the device 1 in the direction of the culm, change the clamping position with respect to the grain culm, and adjust the handling depth.

In summary, the present invention provides a first conveying device in which one of the combined conveying paths R ₁ and R ₁ and the vertical conveying path R ₂ are formed in series by one endless rotation band 8 in the above-described combine harvester. 9, and a second conveyance device 10 forming the other of the combined conveyance routes R ₁ and R ₁
, and in order to adjust the handling depth, both the conveying devices 9 and 10 are installed so as to be able to swing up and down integrally around the horizontal axis P on the conveying end side of the first conveying device 9. Features.

In other words, when adjusting the handling depth, it is possible to eliminate the relative displacement between adjacent conveying devices in the conveying direction as in the past, and to avoid disturbances in the conveying posture associated with grain culm transfer caused by adjusting the handling depth. ,Moreover,
Since the first and second conveying devices 9 and 10 are displaced in the culm length direction with respect to the grain culm from the lifting device 1, when the culm is large, a relatively high position of the grain culm is clamped, and on the other hand, If the culm is short or long, conversely, hold the lower position, regardless of the change in culm length.
As the handling depth is adjusted, the grain culms can be clamped at the appropriate position, and the grain culms can be transported smoothly from the lifting device 1. I was able to do it well without any problems.
