Description

[Detailed description of the invention] Conventionally, the binding device installed at the rear of the threshing device of a combine was equipped with a guide plate that guided the waste straw that was raked into the culm collecting section by the packer, but the rear end was located near the door. As the straw was collected at the collecting culm in front of the door, it spread backwards and became disorganized, resulting in poor bundles of straw, as well as mishandling and clogging of the straw bundle to the straw bundle conveyor. There was a drawback that this occurred.

In addition, even if a transfer guide plate is provided only at the part corresponding to the starting end of the straw bundle conveying device, the ears of collected straw cannot be kept well organized, and are not handled deeply by the threshing device. or when the bundle is moved to the panicle side using a root leveling device, or when the short culms are tied near the plant base so that the center of gravity of the bundle is closer to the panicle than the locking position of the release arm.
The transfer of the waste straw bundle to the waste straw transport device became unsmooth, and during the transfer, the straw bundles did not rotate sufficiently around the ear side, resulting in disordered transfer and transfer postures.

The present invention improves the above-mentioned drawbacks and provides a straw removal guide device for a tying machine in a combine harvester, which can smoothly guide the straw bundles while suppressing the transfer of the tip side of the straw bundles transported by the straw bundle conveying device. A combine harvester equipped with a tying device on the straw discharge side of the threshing device, and a straw bundle conveying device for conveying the straw bundles discharged by the tying device toward the harvested field. A guide plate is provided extending from the front part of the bundling device to its collecting culm, and a rear guide plate is provided at the rear end of the guide plate that slopes upward and extends from the straw bundle receiving part to the part where the ears are collected. In addition, the guide plate and the rear guide plate are configured in an inverted shape with the apex near the door when viewed from the direction of the culm of the bundled waste culm, and the rear guide plate is arranged along the straw bundle conveying device. It is characterized in that it extends almost to the end of the conveyance.

The embodiment shown in the drawings will be explained below.A

0 and crank rod 41 and swing arm 42
Since the rod 32 is moved back and forth through the rear part, the root leveling board 31 hits the base end of the collected straw, centering on the rear part, to sequentially level the straw.

Next, to explain the operation, the straw discharged from the rear end of the straw removal conveyor 1 rapidly falls through the wide gap between the steeply inclined guide plate 13 and the star foil 15, and the straw at the base of the stock and the tip The star foil 15 also rakes the culm toward the collecting culm 7 while lying on the front end of the gently inclined guide plate 14 .

At this time, the star foil 15 is approaching the gently inclined guide plate 14 with a slight gap, so that the stalk side and the ear side of the waste straw are raked in at two places, and the star foil 15 is raked in at two places.
Since the raking locus is lapped when viewed from the side, the packer 10 takes over the waste straw raked by the star foil 15 while lightly pressing it with guide rods 19 and 20, and rakes it into the culm collection part 7.

At this time, the waste straw is supported and guided by the gently sloped guide plate 14 and collected at the collection culm 7 on the front side of the door 8, and the collected waste straw is received by the rear guide plate 23 and then moved between the gently sloped guide plate 14 and the rear part. The guide plate 23 is connected to the apex portion forming an inverted U-shape, and the particles are gathered together in a well-organized state.

Then, when the door 8 senses a predetermined amount of focused pressure and engages the clutch once, the needle hooks the string.
The knotting section 11 operates, and the discharging arm 12 throws the stalk side of the straw bundle backwards while removing knots, and the straw bundle is blocked with the ear side by the guide spring 22, and is directed diagonally downward from the knotting guide 43. Protruding guide rod 4
4 is a straw bundle conveying chain 24 and a clamping guide rail 26a
The straw bundle conveying chain 24 is guided to the starting end of the straw bundle.
A straw bundle conveyor consisting of a and a clamping guide rail 26a conveys the straw bundle diagonally toward the rear of the mown field, and the ears of the straw bundle being conveyed are restrained from being transferred by the rear rear guide plate 23. During the transition, it turns around the panicle side, and at the side end, it is stopped by the rising portion 23a of the rear guide plate 23 and falls in a posture in the front-back direction.

In addition, 45 is a string ball basket.

The present invention provides a combine harvester equipped with a tying device on the straw discharge side of the threshing device as described above, and a straw bundle conveying device for conveying the straw bundles discharged by the tying device toward the harvested field. A guide plate is provided extending from the front part of the bundling device to its collecting culm, and a rear guide plate is provided at the rear end of the guide plate that slopes upward and extends from the straw bundle receiving part to the part where the ears are collected. In addition, the guide plate and the rear guide plate are configured in an inverted shape with the apex near the door when viewed from the direction of the culm of the bundled waste culm, and the rear guide plate is arranged along the straw bundle conveying device. Since the straw is extended almost to the end of the conveyance, the straw scraped by the packer is guided by the upper surface of the guide plate and moves to the culm in front of the door. At roughly corresponding locations, the ears of straw will be received by the rear guide plate, and the ears of straw will be received near the apex of the inverted V-shaped shape formed at the joint between the guide plate and the rear guide plate. It is possible to bundle the straw bundles in a well-organized state on the side, and when the straw bundles are transferred to the straw bundle conveying device, it is possible to prevent mistakes and clogging due to loose straws.

In addition, when the straw removal device transports the straw bundles released from the tying machine, the waste straw that is being collected in front of the door is received by the rear guide plate to the ear side, so that the straw being transported is It is possible to prevent the straw from being separated from the bundle and being thrown out together with the straw bundles.

Furthermore, the panicle side of the straw bundle being conveyed is guided by the rear guide plate while suppressing its movement, so that it may move toward the panicle side due to root alignment during culm collection, and even if the straw bundle is short, the straw bundle may not move toward the panicle side. It can be smoothly rotated around the center and transported and discharged to the mowed field in an orderly manner.
