The present invention is to install a mowing device in the lower rear of the traction erecting device to introduce more than three rows of grain stems, and to the upper side of the mowing device to scrape the back packer group and scraping back The two conveying paths of the left and right are supported as the conveying paths of the left and right two systems, and the two conveying mechanisms, which are conveyed in the upper rear part and merged near the center of the cutting width, are installed and joined. At the confluence of the ear section retaining and autonomous stem feeding device, where the front end of the feed chain, which is installed laterally outwardly of the threshing device mounted on the rear part, is supplied as a lateral bone posture. The conveying chain facing the grain stem surface to the grain stem roots conveying device which has been installed by extending backward to the side, and the narrowing rail and its rail opposite to the chain are elastically biased toward the chain. The basement rail frame, the supporting frame of the conveying chain and the rail frame are configured as a frame lever connecting the intergranular root portion moving passage to the lower part. It relates to a combine configured to adjust the threshing depth by swinging up and down.

The combine of the above-mentioned structure scrapes the cutting grain back to the rear as a rotating packer group, and then transfers it in a V-shape toward the center of the rear as a two-way conveying device and merges it to the side to the upper side of the harvesting device. As a sideways conveying apparatus of right and left side, the conveying path direction is compared with that of the conveying type which is generally used in the conventional art, in which the side conveyance is merged in the middle of the harvesting width, and then is converted at right angles and conveyed to the rear. It is characterized by low sudden change and no confusion on the conveyance between grains. The confluence between grains is located behind the harvesting device, so the front and rear lengths of the whole harvesting front processing section are long. If the mowing front processing section protrudes forward, the turning radius of the front end of the mowing front processing section is large when the aircraft turns. Will be difficult to steer, turning in place or yirang part are also needed significantly.

Therefore, in order to shorten the distance from the crawler traveling device to the front end of the harvesting pretreatment unit, the whole harvesting pretreatment unit is changed to the rear side, whereby the grain stem base conveyance for adjusting the threshing depth that protrudes to the rear from the grain interstitial part position The rear end of the device was positioned behind the front end of the crawler traveling device, so that the lowering amount of the descending device could not be sufficiently caught when the grain stem transport device was swinged downward when harvesting a long grain stem.

That is, in this type of composite mowing machine, there was a drawback in inadequate adaptability to the long grain stem when threshing depth adjustment was performed.

The present invention has been made in view of such a situation, and the long length is ensured without sufficiently increasing the distance from the crawler traveling device to the front end of the pre-treatment unit, and also to sufficiently secure the amount of fluctuation in the lower part of the grain stem root transport device. It aims to make good adjustment of threshing depth with respect to grain stem.

In the combine of the structure described in the initial part characterized by the present invention for achieving the above object, the conveying end portion is moved to the outside in the lateral direction as the above-mentioned intermittent intergranular interposition pinch conveying device swings downward In addition to setting the point shaft center, the front and rear width of the U-shaped portion of the lower part of the frame lever is widened in the form of a shape that is wider in width and narrower in view of the front and rear direction. When in the area, the U-shaped portion of the frame lever described above overlaps in a substantially parallel position to the lateral outward side of the crawler traveling device projecting forward of the mounted threshing device. As follows.

In other words, the intergranular root canal conveyance device for threshing depth adjustment is able to swing not only up and down, but also left and right around the front point shaft center. It is also suitable for supplying the conveying curved section to the feed chain side by side as it swings downward and shifts laterally outward.

In addition, when lowering and swinging the intergranular root canal conveyance device, the rail support frame lever protruding to the lower part interferes with the crawler traveling device. By moving to the side, the rail frame supporting frame lever protruding from the lower part of the conveying device becomes easy to overlap in the lateral outward direction of the crawler traveling device, thereby making it possible to further secure the descending amount of the grain stem base conveying device. To be.

In addition, the U-shaped portion of the frame lever is wider in side view, and the width is narrow in view of the front and rear direction, so that the intervertebral root portion of the conveying music can be easily passed through the wide gap of the U-shaped portion. In addition, there is little protruding outward from the U-shaped portion of the crawler traveling device and there is no fear of pulling the uncut grain as a frame lever, and harvesting can be satisfactorily performed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The drawing shows a three-row mowing combine and is equipped with a threshing device (3), a control unit (4), and an engine (5) on a traveling platform (2) equipped with a pair of crawler traveling devices (1) and (1) left and right. To the front of the traveling stage 2, the cutting front processing unit 6 is connected up and down freely about the point p by the hydraulic cylinder 7.

The above-mentioned cutting front processing unit 6 has three sets of traction erecting devices (9) for pulling up and standing the grain stems planted in the pipe frame (8), which are vertically swinging around the point (p). Equipped with a conveying means for conveying and feeding the Varican-type harvesting device 10 for cutting the root portion of the standing grains and the harvesting grains to the feed chain 11 hypothesized along the outer side of the threshing device 3. The details of the conveying means will be described below. In the upper part of the mowing device 10 described above, rotary packers 12a, 12b, and 12c which scrape three rows of mowing grains to the rear, respectively, are provided, and the auxiliary conveyance belts with conveying projections are respectively faced forward from the upper part. (13) It is configured to cut without protruding protrudingly and gently pulling the grain stem which has been erected to the harvesting device 10 to fall forward.

The rotary packers 12a and 12c at the left and right ends are driven to rotate, and the intermediate rotary packer 12b is interlocked with the left one 12a, thereby allowing a pair of cutting pieces in the left two rows to face each other. After cutting by the rotary packer (12a) (12b) is scraped and joined immediately, the left row of cutting grain is scraped back independently by the rotary packer (12c).

In addition, the upper and lower rotary packers 12a and 12c at the left and right ends support the scraped grain cutting section in an upright position, and are conveyed in the upper and rear two pairs of left and right conveying mechanisms 14 and 15 as a conveying path of two systems. Is installed.

Each conveyance mechanism 14, 15 is comprised from a grain stem root holding device 14a (15a), and a grain paper conveying device 14b, 15b, respectively, and each grain stem root holding device 14a (15a) is carried out. ), The chain is also used for the drive chain of the rotary packers 12a and 12c.

And both conveying apparatuses (14) and (15) are arranged in a V-shape which is narrow in the rear side, and two conveying grains are finally joined in the portion near the center of the harvesting width at a suitable distance from the harvesting apparatus (10).

In addition, the ear portion of the right conveying mechanism 15 extends toward the front end of the feed chain 11 toward the front end of the feed chain 11 and greatly extends to the rear, and at the lower end of the conveying end, a relay conveying apparatus for relaying ( 16) is equipped. In addition, the intermittent root portion interstitial conveyance device 17 extends and protrudes toward the back from the lower part of the above-mentioned grain stem confluence part in a support shape, and the intermittent grain stems are interposed between these interstitial root portion pinch conveying devices 17 and the ear section retaining conveying device. As the latter half of (15b), it is supported by two stages up and down and conveyed to the rear side, and then it is supplied to the front part of the feed chain 11 in a side posture attitude.

The above-described grain stem root canal conveyance device 17 is configured to swing up and down about the point axis center X of the front end, so that the grain stem is changed in the direction of the grain stem with respect to the feed-in 11, and thus The function of adjusting the amount of grain stem insertion and what is called threshing depth amount to threshing steel 3 is provided.

Next, the supporting structure of the grain stem base holding device 17 described above will be described in detail.

The pipe frame 8 of the cutting front processing unit 6 is also used in the transmission case for inserting and supporting the traction erecting teeth 9, the harvesting device 10, and the electric shaft 18 for driving the cutting intermittent conveying means. , The output shaft 20 for driving the intermittent root portion interstices conveying device 15a of the right side is equipped with the notification switch unit 19 which protrudes upwardly and intersects at right angles in the middle of the pipe frame 8. Bevel gears are interlocked with the coaxial 18.

Then, near the root portion of the notification switch 19 described above, the notification switch 21, which is obliquely forward and laterally outward, branches off, and at the distal end of the notification switch 21, an approximately L-shaped rotation case ( 22) is rotated around the boss axis.

In the rotating case 22 and the intermediate rotary shaft 23 interlocked with the bevel gear to the output shaft (20). An output shaft 24 interlocked with a bevel gear is further provided on the biaxial 23, and the output shaft 23 is configured on the drive shaft of the intermittent root portion interposition conveyance device 17 for threshing depth adjustment. The grain stem base sandwiching and conveying device 17 has a conveying chain 17a having a lateral outward side as a sandwiching conveying surface, a sandwiching rail 17b opposite to this, and a rail 17b of which is elastic to the chain 17a side. It is configured as a frame lever 17e which connects the rail frame 17c and the support frame 17d and the rail frame 17c of the conveying chain 17a to the lower part by passing the curvature root portion moving passage downward. One support frame 17d is fixedly connected to the rotation case 22.

Therefore, as the pivoting case 22 is rotated with respect to the notification switch 21, the intermittent root portion narrowing conveying device 17 swings up and down as the boss subaxial center X as the central shaft center, and also descends laterally as it descends. It is to move toward.

In addition, the U-shaped portion of the frame lever 17e described above is bent and formed into a shape that is wider in front and rear width when viewed from the side, and narrower in width when viewed in the front and rear directions, and the intervertebral root portion narrow conveyance device 17 is lowered. At this time, the frame lever 17e overlaps the lateral outward of the left crawler traveling device 1, and the U-shaped portion is configured to be substantially parallel to the outer surface of the crawler in plan view.

Therefore, the intergranular basal articulation conveying device 17 is sufficiently lowered and swinged to be unable to be sufficiently adjusted in the shallow threshing direction, thereby increasing the adaptability to the long grain stem.

In addition, the above-mentioned intermittent muscle interposition transfer device 17 is driven and controlled by the electric motor 25 with the reducer attached to the pipe frame 8, and fixed to the support frame 17d of the transfer device 17. The arm 26 is connected via the rod 28 to the operation arm 27 which is decelerated and driven as the motor 25.

The electric motor 25 is automatically controlled in response to the grain stem length detected by the grain stem length detecting sequencer 29 provided on the back of the traction stand apparatus 9, and is controlled by the threshing apparatus 3 by this control. The amount of intercalation is kept approximately constant despite variations in the length of the grain.
