DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cereal stalk transport structure of a self-removable combine for performing three-row harvesting.

[0002]

2. Description of the Related Art In recent years, in a grain culm transport structure of a three-row combine, a rotary packer made of plastic or the like is often used for scraping and joining of culled grain culms in order to simplify the structure and reduce the weight. It has been, for example,
As shown in US Pat. No. 45149, three rotating packers are used. Then, the harvested grain stalks scraped by each packer are conveyed backward and joined by a pair of left and right stock transfer chains extending rearward from the packer and joined together. Delivered to a supply and transport device that can swing up and down around the fulcrum, and transported upward and backward,
It is configured to change the posture of the transported culm to the sideways posture and supply it to the threshing feed chain.

[0003]

However, in the above conventional example, the transmission system for driving the rotating packer and the stock transfer chain acting on two of the three cut grain culms among the three cut grain culms, The rotating packer acting on one of the cut culms of the stalks and the transmission system for driving the stock transport chain are separately provided on the left and right. For this reason,
It is necessary to provide power output units at two places on the left and right in the front part of the mowing pre-processing unit, which tends to increase the number of power transmission components and the weight of the power transmission system, leaving room for improvement. An object of the present invention is to simplify, reduce the weight, and reduce the size of the rotary packer by configuring the rotary packer to be rational.

[0004]

In order to achieve the above-mentioned object, the present invention comprises a group of rotating packers acting on the root of a three-row cut grain culm, and a pair of right and left plants rearward from above the rotating packer. The original transport chain is extended and interlocked, and the harvested grain stalks scraped by each rotating packer are transported backward and merged along the two paths by the stock transport chain, and the combined grain culms are moved up and down around the rear fulcrum. Combine grain culm transport structure configured to be delivered to the swingable harvesting grain culm supply transport device and transported upward and backward, and to change the posture of the transported grain culm to the sideways posture and supply it to the feed chain of the threshing device, In the rotating packer group, a pair of 2-row rotating packers that collectively scrape the stocks of two cut grain culms of the three cut grain culms and one of the three cut grain culms. Scraping the root of the cut culm A pair of single-row rotary packers, wherein the outer diameter of each of the pair of single-row rotary packers is smaller than the outer diameter of each of the pair of double-row rotary packers. All the rotary packers of the pair of rotary packers and the pair of two-row rotary packers are engaged with each other so as to interlock with each other, and the stock transfer chain interlocked with the single-row rotary packer; and the two-row rotary packers. One of the stock transfer chains, or the pair of single-row rotary packers,
It is configured to drive any one of the pair of two-row rotary packers.

[0005]

The rotation packer is driven by inputting to any one of a pair of single-row rotary packers and a pair of two-row rotary packers, and the rotating power of the rotary packer is applied to all rotations. The meshing of the packer transmits to all the rotating packers except the input packer, and the rotating power of the rotating packer is transmitted to both stock transport chains by interlocking the rotating packer and the stock transport chain, and all the rotary packers and the left and right Drive the stock transfer chain. Or, input to either one of the left and right stock transfer chains to drive this stock transfer chain, and the rotational power of this transfer chain is entirely controlled by the interlocking of this chain and the rotating packer and the engagement of all the rotating packers. , And the rotational power of the rotating packer is transmitted to this stock transport chain by interlocking the rotating packer and the other stock transport chain, thereby driving all the rotary packers and the left and right stock transport chains. . That is, all the rotary packers and the right and left stock carrier chains can be driven in synchronization with the power from one output unit in the pre-cutting processing unit. Since the single-row rotary packer rakes into a smaller number of cut culms than the double-row rotary packer, the single-row rotary packer has a smaller outer diameter than the double-row rotary packer. As the two-row rotary packer, adopt a rotary packer with a larger outer diameter than the one-row rotary packer,
Compared to the use of a rotary packer having the same outer diameter as the single-row rotary packer and the double-row rotary packer, both the two-grained grain culm and the single-grained grain culm are smoothly scraped and transported, In addition, each rotating packer is installed while keeping the space for installing the packer small.

[0006]

Thus, according to the present invention, the transmission structure for driving the rotary packer and the stock transfer chain can be made simple and lightweight with only one output unit, and all the rotary packers can be used. A combiner that can be arranged in a relatively small space and can transport the harvested culm with a rotating packer in a simple structure can be obtained with a simple structure, light weight and compactness from the viewpoint of the transmission structure and the installation of the packer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG.
The front side of the mowing combine is shown in FIG. This combine
A cutting pre-processing unit 4, which is provided with a crawler traveling device 1 and has a threshing device 2 mounted thereon, is connected to a front portion of a traveling machine body equipped with a threshing device 2, which can be vertically moved and oscillated by a hydraulic cylinder 3 around a horizontal axis P at an upper rear portion. ing. The pre-cutting unit 4 includes a three-row raising device 5, a clipper-type cutting device 6, and a pair of left and right large-diameter two-row rotating packers acting on the root of the left two-cutting grain culm. 7a and 7b, and a pair of left and right two-row rotary packers 7a and 7b acting on the root of the right one cut grain culm
A single-row rotary packer 7c and 7d having a smaller outer diameter, and a squeeze-and-convey mechanism 8a with elastic projections extending forward from above a pair of left-side two-row rotary packers 7a and 7b. , 8b and the rightmost single-row rotary packer 7
and a squeeze and transport mechanism 8c with elastic projections extending forward from above the upper part of d, a stock transport chain 9a and a stock transport chain 9a extended rearward from the upper part of the leftmost two-row rotary packer 7a. A tip-locking transport mechanism 10a, a stock feeder chain 9b and a tip-locking transport mechanism 10 that extend rearward from the upper part of the rightmost single-row rotary packer 7d.
b, and a cutting grain culm supply / transportation device 12 for supplying the cutting grain culm to the threshing feed chain 11 in a sideways posture. The rotary packers 7a and 7d are arranged such that the axial positions of the single-row rotary packers 7c and 7d are ahead of the axial positions of the double-row rotary packers 7a and 7b so that the front end positions thereof are aligned on the left and right straight lines. And all the rotating packers 7a... 7d are interlocked and interlocked with each other. Then, the stock transport chain 9a on the left side is driven by the power from the transmission case 13, and from there, the chain is transported to the tip locking transport mechanism 10a, the full rotation packers 7a... 7d, and the full scraping transport mechanisms 9a. Driving power is transmitted, and power is further transmitted from the rightmost one-row rotary packer 7d to the right stock transport chain 9b and the tip-locking transport mechanism 10b, so that these are driven synchronously. ing. In addition, the cutting grain culm supply and transport device 12
