DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-removing combine grain culm conveying means provided with a whole grain culm introduction device for introducing a whole cut short culm into a threshing unit.

[0002]

2. Description of the Related Art An entire grain culm feeding device in which a starting end or an end of a rail is rotatable upward integrally with a rail base and a starting end of the rail is separated from a feed chain, It is described in JP-A-55-19019 or JP-B-60-57808.

[0003]

SUMMARY OF THE INVENTION The above-mentioned JP-A-55-19
In the apparatus described in Japanese Patent No. 019, the starting end of the rail is separated from the feed chain. Therefore, even if the grain stalk conveyed from the pretreatment device reaches the starting end of the feed chain, it is moved to the rail and the feed chain. Because of this, it is not possible to carry over to the handling room directly, and it is necessary to push and insert it directly into the handling room. Therefore, it is not possible to supply the food smoothly into the handling room, and there is a problem that the grain stalk stagnates and clogs at this portion. Moreover, since the thing described in the above-mentioned Japanese Patent Publication No. 60-57808 displaces the end of the rail near the feed chain, even if the whole cereal stem is pulled into the handling room at this part, The grain culm is inserted near the end of the handling room, and there is a problem that the processing process in the handling room is short and threshing cannot be performed sufficiently. Further, since the rails described in both of the above publications are configured such that the rail is rotated integrally with the rail base at one point and separated from the feed chain, the rotating rail is separated from the other rails. It is necessary to separate the rails from each other, so when the rails are in the normal pinching and transporting state, the rail that rotates following the grain thickness to be transported and the other rails move up and down independently of each other. ,
There is a problem that a step or the like is easily generated at a connecting portion between the two rails, which causes conveyance turbulence and clogging.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a feed chain is provided on the side of a handling chamber containing a handling drum, and a rail pin is provided above the feed chain via a rail pin. Ears of cereal culm are supported by a rail base movably up and down and connected with a large number of links urged downward by elastic members. In the self-removing type combine which threshing is performed by inserting the side into the handling room, of the multiple links, the link on the starting end is continued to the link on the starting end while the link on the starting end is kept close to facing the feed chain. The switching link is configured to be switchable between a clamping position facing and close to the feed chain and a position upwardly separated from the feed chain, and the switching link is positioned within the front-rear width of the handling cylinder. Disposed on at least the starting end side nearest towards the and thresher side, the switch the switching link at a position spaced upwardly relative to the feed chain, and is nipped and conveyed state of the culms by the feed chain and the switching link is released,
The whole cereal stem is drawn into the handling room by the rotation of the handling cylinder. Also, the present invention provides a rail by rotatably connecting a number of links to each other, providing a rear link on the rear side of the switching link, and connecting a link on the starting end and a link on the rear end. The switching link is moved upward relative to the rail base while maintaining the connection state with the links at the start end and the end side while keeping the switching link facing the feed chain. The position is switched to a position separated upward.

[0005]

With the above configuration, the present invention has the following effects. If the cutting culm is short, switch the switching link to the non-clamping position, which is separated upward from the feed chain. At this switching link position, the entire grain culm is drawn into the handling room by the handling cylinder and threshed well. Can be processed. At this time, the grain culm that has reached the start end of the feed chain is once pinched and conveyed by the feed chain and the link on the start end side, and in a state where the spike side is supplied into the handling room, the pinch and conveyance state of the grain culm at the switching link position is changed. Will be released,
Such a grain stalk can be quickly pulled out into the handling room by the rotation of the handling cylinder, and stagnation of the grain stalk and clogging of the transport can be prevented. Since the switching link is arranged at least near the starting end of the handling cylinder, the grain culm is pulled out by the handling cylinder near the starting end of the handling room, so the grain culm pulled out and put into the handling room as a whole,
The threshing action is exerted over a long stroke by the handling cylinder, and the threshing treatment can be performed more favorably.

[0006] Furthermore, with the rail base fixed without being divided as in the prior art, only the switching link is kept at a position upwardly separated from the feed chain while maintaining the connection state with the start end and the end side links. Even when the switching link is set at the normal pinching and conveying position and the grain culm is pinched and conveyed by switching, the switching link and the links before and after the link are connected following the grain culm thickness. The rails can be moved up and down in conjunction with each other, and the culm can be smoothly sandwiched and conveyed without causing the rails to be in a stepped state as in the related art. In addition, the upward movement of the switching link with respect to the rail base must be performed against an elastic member that urges the switching link downward, but a link on the end side is also provided on the rear side of the switching link, and the link on the starting end side is provided. The whole culm can be put into the handling room by raising only the intermediate switching link and switching to the non-clamping position while keeping the link and the link on the end side facing and close to the feed chain. However, for example, compared to a case where all the links on the rear side other than the link on the starting end side are configured as switching links,
The load for switching the switching link to the non-clipping position can be reduced as much as possible.

A wire holder 53 is fixed to the other end of the wire 51, and the wire holder 53 is rotatably inserted into a pin 56 fixed to one side of a slide guide plate 55. The slide guide plate 55 is slidably attached to the operation panel 57. One end of a return spring 59 is fixed to one side of the slide guide plate 55 opposite to the pin 56, and the other end is connected to the operation panel 57. Fixed. Also, the slide guide plate the total amount closing lever 60 in the opening hole 55a for actuating the cam 30 of 55 (actuating means) and is inserted,該全amount closing lever 60 is freely distribution rotated about the supporting point 61 Has been established.
Further, a pin 62 is fixed to the lower portion of the full-amount feeding lever 60, and a wire holder 65 fixed to one end of a wire 63 is rotatably inserted into the pin 62. One end of the wire 63 is connected to the wires 32 and 40. When the shift lever 43 does not come into contact with the cam plate 46, that is, when the shift lever 43 does not shift to the high speed side, the slide guide plate 55 and the wire 5
1 and the cam plate 46 are pulled, the cam plate 46 comes into contact with the stopper pin 49, and the shift lever 43 shifts to the high speed side to rotate the cam plate 46, so that the wire 51 and the slide guide plate 55 Is pulled and moves,
The full-amount feeding lever 60 abutting on the opening 55a of the slide guide plate 55 is rotated so that the return spring 59 is extended.

That is, the speed change lever 43 is moved to the low speed position 45b.
, The full-load lever 60 is returned and the spring 5
9, the wires 63 and 32 are pulled and the cam 30 connected to the link moving lever 29 is pulled.
Is rotated, the connecting plate 27 moves upward, and the rail pins 2
The switching links 22 ', 22' connected to 6, 6 and 26 are lifted to a position away from the feed chain 9, and a gap is formed between the feed chain 9 and the switching links 22 ', 22'. At the same time, the wires 63 and 40 are also pulled, and the grain stalk guide 36 rotates upward, so that the projections of the rail pins 26 and 26 of the feed chain 9 are hidden in a side view. For this reason, the grain squeezing force and the conveying force of the feed chain 9 and the rail 25 are lost, and the grain stalks nipped and conveyed between the feed chain 9 and the foremost part of the rail 25 are pulled out by the entire handling cylinder 2. Since all of the grains, straws and the like are agitated and processed in the handling room 6, the unhandled amount can be significantly reduced. At this time, the full-amount feeding lever 60 is in contact with one end of the opening 55a of the slide guide plate 55 at a position slightly beyond the expected point, and is stably held at this position.

When the shift lever 43 is shifted to the high speed side by the low speed position 45b, the cam plate 46 is rotated, the wire 51 and the slide guide plate 55 are pulled, and the wire 51 and the slide guide plate 55 come into contact with the opening hole 55a of the slide guide plate 55. The full-amount input lever 60 is tilted toward the pin 56 and is turned off. As a result, the wires 63 and 32 are loosened, so that the cam 30 connected to the link moving lever 29 is turned to the horizontal position, the connecting plate 27 is moved downward, and the rail pins 26 and 26 are moved.
The lower ends of the switching links 22 ', 22' connected to the feed chain 9 come into contact with the feed chain 9, and there is no gap between the feed chain 9 and the switching links 22 ', 22'. At the same time, since the wires 63 and 40 are loosened, the grain stalk guide 36 rotates downward by its own weight and abuts against the stopper pin 42, and the rail pins 26 and 2 of the feed chain 9.
The six projections become visible in side view. For this reason,
Grain squeezing force and conveying force of the feed chain 9 and the rail 25 are restored, the total amount is automatically released, and the grain stalks nipped and conveyed between the feed chain 9 and the rail 25 are threshed in the handling room 6. The treated and threshed grain culm passes through the handling room 6 by the feed chain 9, and the waste straw feed chain 11
Passed to. As a result, if the efficiency is increased by feeding the whole grain culm, the processing capacity of the handling room 6 is exceeded and the handling room is damaged or broken down. However, such a decrease can be avoided. In the state where the shift lever 43 is on the high speed side,
Since the full charge is automatically released, no erroneous operation can occur. Further, since the full-amount input lever 60 corresponds to the driver's seat, it is possible to switch over to the full-amount input at hand, which is extremely simple and can immediately cope with a harvesting situation. In addition, since the feed chain 9 has a pinching / transporting ability between the leading end (link at the start end) of the feed chain 9 and the rail 25, the grain culm reaching the start end of the feed chain 9 is
Is once conveyed at the foremost portion between the hull and the rail 25, there is no backlash at the threshing entrance, and the total amount of grain culm is at the switching links 22 ', 22' located near the side start end of the handling cylinder 2. Input can be performed quickly and reliably.

Based on the above configuration, when the harvested culm is short or the ears are not well aligned, the full-amount input lever (operating means) 60 is set to the on state, and the support member A fixed to the body is moved vertically. A plurality of rail pins 2 slidably inserted
The link members 26 and 26 are pulled up by the link moving means 24 against the elastic force of the rail spring (elastic member) 21 provided between the support member A and the link 22 to be connected to the rail pins 26 and 26. A plurality of successive switching links 22 ', 22' are also pulled upward.
At this time, a plurality of continuous switching links 22 ', 22'
, The switching links 22 ', 2
Since 2 'is raised in parallel, it is not necessary to greatly raise the tip as in the case of rotating at a single fulcrum. Even if the lifting amount is substantially reduced, the feed chain 9 and a plurality of continuous switching links 22' are required. , 22 ′, the entire length of the cereal stem can be introduced. When the harvested culm is long, the support member A and the link 22
The rail pin 26 is urged downward by the elastic force of the rail spring (elastic member) 21 provided therebetween. In other words, by moving only the switching links 22 ', 22' in the vertical direction, the rail 25 can be switched between the fully loaded state and the nipping and conveying state.

Further, in this embodiment, the function of the whole amount feeding device can be sufficiently exhibited even without the grain stalk guide 36, so that the whole amount feeding device without the grain stalk guide 36 can be provided. Further, the present embodiment can be applied so that when the grain culm or the short culm lays down, it is detected by the handling depth sensor, and the full-batch input function is activated in conjunction with the signal.
