た。[Detailed description of the invention] Conventionally, the ear-side conveying body for conveying the harvested grain culm of a combine toward the threshing device has been used, as shown in FIG. When pushed to the top, the conveyance claws of the ear-side conveyor took over, so the ear of the grain culm temporarily stagnates between the grain culm lifter and the front part of the ear-side conveyor, and the tip of the ear is not conveyed. There was a disadvantage that the process was delayed and tangles occurred, resulting in many split ears, culms, and culms being pulled out during threshing.

る。 The present invention is a grain culm conveying device in a combine harvester that is capable of reliably transferring the grain side of the grain culm raised by the grain culm pulling body to the conveying claw of the ear side conveying body without stagnation, regardless of the length or shortness of the grain culm. When viewed from the side, the rear of the stock head conveyor and the ear side conveyor interposed between the reaping device and the threshing device are vertically movable centered near the starting end of the feed chain of the threshing device. In a combine harvester in which the grain culm supported by the pulling claw of the grain culm pulling body of the reaping device is inherited by the stock base conveyor and the ear side conveyor, the grain side conveyor is moved up to the top. At the upwardly tilted position, the tip movement locus of the conveying claw of the ear-side conveying body and the tip moving locus of the lifting claw of the grain culm pulling body are made to overlap and synchronized at the timing when the conveying claw passes between adjacent lifting claws. It is characterized by the fact that it has been forced.

is a threshing device mounted on one side of the machine base 3 having a traveling device 2, and in front is a grain culm lifting body with a chain attached to it with a cutting body 4 and a number of lifting claws 5. 6, 6, cutting blade 7, raking wheel 8, 8, stock raking chain 9, 9, and raking belt 10 with lug,
A reaping device 11 consisting of 10 etc. is mounted so as to be tilted up and down about a horizontal axis 12, and between the reaping device 11 and the threshing device 1, a clamping rail is provided oppositely on the conveying surface of the conveying chain. An ear-side conveyor 1 consisting of a stock-side conveyor 13, a chain 14 to which a large number of conveyor claws 14a are attached so as to be able to rise and fall, and a guide rail 15.
6, and the rear part of the ear side conveyor 16 and stock head conveyor 13 is provided with a vertical shaft 18 rising from a gear case 17 mounted on the horizontal shaft 12 so as to be tiltable back and forth.
The handling depth adjustment lever 20 provided on the side of the driver's seat 19 is connected to the stock base conveyor 13 via a link 21, so when the handling depth adjustment lever 20 is tilted back and forth, The stock head conveyor 13 and the ear side conveyor 16 tilt up and down about the horizontal axis 12 located near the starting end of the feed chain 1a of the threshing device 1 when viewed from the side.
そして、前記穂側搬送体１６は第９図に示すそ

は同期せしめてある。 The ear-side conveyor 16 protrudes further forward than that shown in FIG. 9, and the amount of protrusion increases when tilted upward to the maximum position B in FIG. If the trajectory of the tip of the transport claw 14a overlaps with the upward trajectory of the lifting claw 5 as shown in FIGS. If the speed V of 5 and the speed v of the conveying claw 14a are multiplied by an integral number such as V/v = 2, the conveying claw 14a passes every other pitch with respect to the lifting claw 5, and when V/v = 1, each pitch is increased. The conveying claw 14a passes between each pitch of the raising claw 5. In other words, the lifting claw 5 and the conveying claw 14a are synchronized.

合うようにして受け取つて搬送する。 Furthermore, as mentioned above, since the ear-side conveyor 16 protrudes more forward than the conventional one, when the angle shown by the solid line in FIG. Although the raking belt 1 protrudes upward more than the raking belt 10 and is easy to come apart, the raking belt 1
The conveyance claw 14
Since the culm is scraped by A, there is no temporary stagnation, and the conveying claws 14a of the panicle side conveying body 16, which is tilted downward to the position A, are sufficiently engaged with the lugs of the scraping belt 10. The grain culms are received and transported like gears meshing together.

The stock transport body 13 is scraped up rearward and upward.

is attached to a rod 25 elastically supported by the holder 24, and a cover 2 is provided on the upper surface of the clamping rod 13b and clamping rail 13c to cover between them and the holder 24.
6 is fixed, and a cover 26 fixed to the clamping rail 13c has a rising portion 26' that is bent along the grain culm to be conveyed.

障害になることがない。 When a grain culm is raised in a soft field, it may pull out and be transported along with its roots. In such cases, the stump is not harvested and is attached to the front and rear grain culms as shown in Figure 8. The stumps are conveyed in a staggered manner and are successively lowered, failing to enter between the clamping rod 13b (or clamping rail 13c) and the conveying chain 13a, and getting caught on the rod 25, resulting in a conveyance obstacle. Since the roots of grain culms, weeds, grains, etc. are received by the cover 26, they do not become an obstacle to transportation.

送することができる。 As described above, the present invention supports the rear parts of the stock head conveyor and the ear side conveyor interposed between the reaping device and the threshing device so as to move up and down at the center near the starting end of the feed chain of the threshing device when viewed from the side. In the combine harvester, in which the grain culm pulled up by the pulling claw of the grain culm pulling body of the reaping device is inherited by the stock base conveyor and the ear side conveyor, the ear side conveyor is tilted upward to the highest position. The locus of movement of the tip of the conveying claw of the ear-side conveying body and the locus of movement of the tip of the raising pawl of the grain culm pulling body are made to overlap at the position and are synchronized at the timing when the conveying pawl passes between adjacent raising pawls. The front end of the ear-side conveyor can be overlapped or extremely close to the grain culm pulling path, and if the grain culm is short, it can be prevented from falling apart or
It can be handed over and transported smoothly without tipping over.
また、長稈でかつ倒伏していた穀稈は柔軟にな

ることができる。 In addition, since the grain culm, which is long and has been lodging, has become flexible, it is attempted to lodge immediately after raising, but while the grain culm is retained by the lifting claw of the grain culm pulling body, the ear It is possible to transfer the grain by scraping it with the conveying claws of the side conveying body, and the ears of the raised grain culm do not temporarily stagnate, disrupt its posture, or cause a delay in the transfer of the ears, as in the case of conventional methods. ,
It is possible to prevent unhandled crops, split ears, split culms, and shedding of culms.
