[Detailed description of the invention] The present invention improves the posture of the culm, which is discharged from the culm discharge port of the threshing machine with the tip side tending to lag behind, by changing the posture of the culm from the end of the culm holding and conveying device installed along the handling port. When passing the tray over the conveyor belt and conveying it, the head of the waste culm is held at one point by one rail plate of the fusei rail and the feed chain, and the panicle side is rapidly raked with the straw conveyor belt. To provide a culm conveying device in a thresher that can correct the waste straw by rotating it at a slow speed around the clamping point, and can also reliably connect the stem part of the rotated waste straw to the waste straw conveying belt. This system is intended to be provided in such a way that the ear side and stock side of the straw are placed on the terminal side of a support rail consisting of a pair of rail plates parallel to the feed chain whose upper surface is the conveying surface along the handling opening. In a threshing machine equipped with a pair of straw conveying belts whose underside is the conveying surface, one rail plate of the support rail faces the chain roller of the feed chain, and the other rail plate is used to feed the straw. A rail plate facing the chain roller of the support rail is formed long so that its terminal end protrudes rearward from the end of the other rail plate, and one rail plate of the support rail is The conveying surface of the feed chain on the opposing part and the conveying surface of the straw conveying belt on the panicle side are lapped when viewed from the culm direction of the straw, and the raking speed of the straw conveying belt on the panicle side is adjusted to feed The conveyance speed of the chain is set to be higher than the chain conveyance speed so that the tip delay can be corrected, and the starting end of the guide rail facing the conveyance belt on the stock side is extended so as to wrap around the descending rotating part at the end of the feed chain. The present invention is characterized in that it is configured to scoop up and guide the stock part of the waste straw from the terminal end of the feed chain to the starting end of the guide rail.

An embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes a handling cylinder mounted on a handling cylinder shaft 3 in a handling chamber 2, and a pair of feed chains 4 and a pair of cylinders arranged at an appropriate distance along the handling opening. A support rail 5 consisting of rail plates 5a and 5b is arranged in parallel, one rail plate 5a is pressed by the chain roller 4a of the foot chain 4 and the K spring 6, and the other rail plate 5a is attached to the spike side. It faces the outside of the chain plate.

Further, a drive sprocket 7 at the end of the feed chain 4 bent diagonally downward using an idler wheel or the like is driven by one output shaft 10 from a gear case 9 supporting the end of the handling barrel shaft 3. .

At the terminal ends of the feed chain 4 and the support rail 5 outside the exhaust culm opening 11, there is a pair of exhaust culm conveyance chains 12 and exhaust culm conveyance chains 12 whose end portions are deviated toward the middle of the width of the machine body and whose lower surfaces are used as conveyance surfaces. The starting end of the culm conveying belt 13 is located next to the culm conveying belt 13, and the starting end turning part of the culm conveying chain 12, which receives and connects the root of the culm, is connected to the downward slope of the terminal end of the feed chain 4, as shown in FIG. The starting end of the culm conveying belt 13, which is provided at a distance from the culm conveying chain 12 toward the panicle side, is connected to the culm opening 11 from the starting end of the culm conveying chain 12. It protrudes to the side and faces a portion where one rail plate 5a of the planting rail 5 and the terminal end of the feed chain 4 clamp the base of the culm.

The end of the other rail plate 5b of the fushu rail 5 is formed to be shorter than the rail plate 5a, as shown in FIGS. 2 and 3, and when viewed from the handling opening side, it has an elongated culm as shown in FIG. 3. It faces the turning part at the starting end of the conveyor belt 13, and when the culm is transferred, it comes off the rail plate 5b facing the outside of the chain plate and moves to the rail on the side away from the chain roller and the machine body. The culm is held at the starting end of the culm conveying belt 13 while being held between the plates 5a, that is, the base of the culm is held at one point.

is bent inward at the middle part and pressed against the lower chain roller of the culm conveyance chain 12, and the guide rod 19, whose base is attached to the outer surface of the outer guide plate 17, The culm is supported and then guided toward the culm conveying chain 12.

Therefore, when transferring the culm, the culm holder is held at one point at the base of the stock as described above and is pulled into the starting end of the culm conveying belt 13, and at the same time or immediately after that, the guide plates 17 and 18 move the culm from the feed chain 4. While the culm is forcibly detached and the plant head side is being slowly conveyed, the culm conveying belt 13 quickly transports the culm to correct the posture of the culm, which is discharged later than the panicle side, and turns around the center of the plant head side. Then, the receiver is also connected to the discharge culm conveyance chain 12 and conveyed.

In addition, guide rails 21 and 22 are provided on the lower surfaces of the exhaust culm conveying chain 12 and the belt 13, which are supported by springs 20 and are used to sandwich and convey the exhaust culm.
The starting end of the guide rail 21 installed opposite to the culm conveyance chain 12 is bent along the panicle side of the feed chain 4 and wraps around the downward rotating portion of the end of the feed chain 12 when viewed from the side, so that the guide rail The starting end of 21 receives and stops the stock part of the swirled waste straw, and guides it to the conveying surface of the waste straw conveying chain 12 without scooping it up.

As mentioned above, the present invention is designed to receive the ear side and stock side of the waste straw on the end side of the support rail, which is made up of a pair of rail plates parallel to the feed chain and whose upper surface is the conveying surface along the handling opening. In a threshing machine equipped with a pair of straw conveying belts with the lower surface serving as the conveying surface, one rail plate of the support rail is opposed to the chain roller of the feed chain, and the other rail plate is used for feeding. A rail plate facing the chain roller of the fusei rail is formed to be long so that its end protrudes rearward from the end of the other rail plate. The conveying surface of the feed chain in the section where the straw is being removed and the conveying surface of the straw conveying belt on the ear side are lapped when viewed from the culm direction of the straw, and the raking speed of the straw conveying belt on the panicle side is adjusted to In order to correct the delay in the tip of the head due to the conveyance speed, the starting end of the guide rail facing the conveyance belt on the stock side extends so as to wrap around the descending rotating part at the end of the feed chain. Since the straw stock head is scooped up and guided from the end of the feed chain to the starting end of the guide rail, during the threshing process, the straw stock base is transported by the two rail plates of the fusei rail and the feed chain. When the shell culm that has been used as waste straw is discharged from the culm opening, the tip side is ejected with a delay, but when the waste straw reaches near the end of the feed chain, the ear side is no longer held between the rail plates and the chain rollers. The straw is clamped at only one point by one rail plate, and in this state, the conveying surface on the starting end side of the straw conveying belt scrapes and conveys the ears at a higher speed than the feed chain. It is possible to easily and orderly turn the entire straw around the clamping point while holding it in place, thereby correcting the lag in the tip of the ears. During the conveyance, the straw is pushed and bent by the rail plate on the ear side of the fusei rail, so when the straw is turned, it is also pushed and bent by one of the rail plates that has entered between both plates of the feed chain. Regardless, the straw does not jump up significantly on the panicle side, and the straw can be easily scraped into the straw conveying belt on the panicle side and the receptacle can be inherited. The receiving straw is stopped and scooped up by the protrusion of the guide rail of the waste straw conveyance belt, and the straw can be received and conveyed reliably while preventing culm leakage and disturbance of the posture.
