Description

[Detailed description of the invention] The present invention relates to a combine harvester with a straw tying machine, which has a foot chain installed along the side wall on the uncut side and a straw tying machine attached to the rear of the combine. It is.

Normally, in this type of combine harvester equipped with a waste straw tying machine, the waste discharged from the combine at the foot chain is
Because the stock part is in a posture that extends greatly from the foot chain toward the uncut side, between the combine harvester and the straw tying machine, there is a part near the end of the foot chain toward the straw tying machine. In addition, a waste straw conveying device that extends in an inclined shape toward the already-cut side is provided, and the waste straw conveying device once conveys the waste straw discharged from the combine in the direction of the already-cut side, and then a waste straw binding machine is installed. The structure is designed so that it can be supplied to a large number of people, thereby ensuring a good bundling operation.

However, in the conventional combine harvester equipped with a straw tying machine, the straw tying machine as described above is arranged in an inclined manner between the combine harvester and the straw tying machine, so that the straw tying machine cannot be placed close to the combine. It had the disadvantage that it could not be energized by the vehicle, which inevitably resulted in a longer overall length and larger size.Furthermore, this made the front-rear balance unstable, making it difficult to run stably.

The present invention aims to provide a combine harvester equipped with a waste straw tying machine that eliminates the above-mentioned drawbacks, and its gist is that the waste straw that is discharged from the combine is placed on the combine side or on the side of the waste straw tying machine. A posture changing means is provided for changing the posture of the straw when brought to the end of the chain to a substantially hanging posture with the tip facing downward;
Above the starting ends of the waste straw passages formed in the waste straw binding machine, each upper part has a conveyance path extending from a portion near the end of the foot chain toward the harvested side by an appropriate amount along the middle direction of the combine. A patent straw is characterized in that a lower auxiliary conveyance device is provided, the transfer end of which is located at a position closer to the uncut side by an appropriate amount than that of the stock transfer device. Located on a combine harvester with a binding machine.

First, an embodiment of the combine harvester with a straw tying machine according to the present invention will be explained with reference to the drawings. In the illustrated combine harvester with a straw tying machine, 1 has a foot chain 2 arranged along the side wall 1a on the uncut side. This is a lower plate type combine harvester.
A position changing means is disposed in the combine 1 for changing the position of the straw when it is discharged from the combine 1 and brought to the end of the foot chain 2 to a substantially hanging position with the tip facing downward. It is set up.

That is, a vertically elongated straw guide passage 4 is formed in the combine harvester 1 from a portion near the terminal end of the handling barrel 3 along the side wall 1a toward the center of the combine harvester 1, and the starting end of the straw straw guide passage 4 and the handling barrel are connected to each other. A straw guide plate 5 is provided between the terminal part of the handling barrel 3 and the straw guide plate 5, which is inclined backwardly and downwardly from the terminal part of the handling barrel 3 and in the direction of the straw guide passage 4, and the straw guide plate 5 is arranged between the terminal part of the handling barrel 3 and the straw guide plate 5. The tip of the straw that is being transferred rearward while being held in the handler 1 is gradually guided downward from the end of the handling cylinder 3 by the straw guide plate 5, without changing its position, and then guided to the straw guide path 4. It is done like this.

Therefore, the waste straw discharged and transferred from the end of the waste straw guide path 4 to the outside of the combine harvester 1 by the foot chain 2 is changed to a substantially hanging position with its ears facing downward.

Reference numeral 6 denotes a waste straw tying machine installed close to the rear part of the combine harvester 1, and this waste straw tying machine 6 has a joint part 8 with a bill holder on the upper side and a waste straw tying machine 6 with a waste straw passage 7 in between. A focusing part 12 is provided with a discharge arm 9 attached to the nodule part 8 and has a packer 10 and a needle 11 on the lower side.
A door 13 is disposed at the end of the straw removal passage 7, and the binding section 8 and the converging section 12 are fixedly supported in a cantilevered manner by a transmission case 14 disposed on the uncut side. The construction and operation are no different from the usual one, except that the knot part 8 converging part 12 and the transmission case 14 are arranged in the left and right directions opposite to the usual one. It is.

Note that 15 is configured to apply a certain resistance to the part of the bundled straw closer to the cut side than the part receiving the action of the discharge arm 9 during the discharge action of the bundled straw, thereby changing the discharge posture of the bundled straw. This is a resistance rod for changing the posture of the cutter towards the already cut side.

Further, above the waste straw passage 7, there is provided a conveyance path extending from a portion near the end of the foot chain 2 to the cut side by an appropriate amount along the width direction of the combine harvester 1.
An upper stock transfer device 16 and a lower auxiliary transfer device 17 are provided, and the configurations of both transfer devices 16 and 17 will be explained next.

That is, the stock head conveying device 16 has its starting end close to the terminal end of the foot chain 2, and its terminal end is located near the side wall of the combine harvester 1 on the harvested side, and is driven together in the A direction on the horizontal plane. A pipe-shaped fixed portion 19 a provided opposite to the starting end side of the stock base conveyance belt 18 is configured to allow the stock base conveyance belt 18 to move. The length of the lever 19 can be adjusted via a set screw 20 screwed into the fixed portion 19a. Therefore, it is devised to be able to change and adjust the length of the conveyance path of the stock conveyor 16, that is, the conveyance end position.

Similarly to the stock transport device 16, the auxiliary conveyance device 17 also includes an auxiliary transport belt 21 which is disposed directly below the stock transport belt 18 at a certain distance and overlapping with the stock transport belt 18.
and a clamping rod 22 consisting of a pipe-shaped fixed part 22a facing the starting end side part of the auxiliary conveyance belt 21 and a rod-shaped adjustment part 22b facing the terminal end side part. It is devised so that the length of the conveyance path can be increased or decreased through a set screw 23 screwed into the portion 22H.

In this embodiment, the auxiliary conveyance belt 21 is configured to rotate in the same direction (direction A) as the conveyance belt 18 at a speed that is an appropriate amount higher than that of the stock conveyance belt 18. There is.

The length of each clamping rod 19.22 is always
The conveying end of the stock is set so that it is located a certain amount closer to the uncut side than the conveying end of the stock base conveying device 16, and the clamping rod 1 is set by a set screw 20° 23.
The length of 9.22 is also adjusted appropriately within a range that satisfies these conditions.

Also, a rod-shaped tip is secured to the rear wall 1b of the combine harvester 1 at a portion closer to the already cut side than the end of the straw guide path 4 and below the starting end of the auxiliary conveyance device 17. A body 24 is provided in a protruding manner, and the tip of the tip locking body 24 is bent upward, and the pinching rod 19 is attached to the bent portion.
．． 22, that is, fixed portions 19a, 22a, on each conveyor belt 18.
A support mechanism 25 for supporting with force so that it can be pressed into contact with 21.
It is fixed.

Next, to explain the operation of the above-mentioned embodiment, the waste straw that has passed through the combine 1 and has been threshed is held at the foot chain 1 by the foot chain 1 and transferred to the combine harvester 1.
When the straw is discharged from the container, it is in a substantially hanging position with its tip facing downward via the attitude changing means, that is, the straw guide plate 5 and the straw guide path 4.

(FIG. 3A) When the waste is brought to the end of the foot chain 2 in this attitude, its stock part is transferred from the end of the foot chain 2 to the stock transport device 16 and the auxiliary transport device 17. Both conveying devices 16, 1 are delivered to the starting end.
7, along the width direction of the combine harvester 1 in the direction of the cut side (direction A), and the tip part is locked by the tip locking body 24, and the conveyance speed of the auxiliary conveyance belt 21. Since the conveyance speed of the stock conveyor belt 18 is set high, the attitude of the tip portion is gradually changed to an inclined position in which it is delayed in the conveyance direction (direction A) (Fig. 3B).
).

Further, the waste straw is transferred in the direction of publication by both of the conveying devices 16 and 17 while its posture is tilted toward the horizontal. When the adjusting portion 22 of the clamping rod 22 comes off from the a end (C in the same figure), and then it comes off from the conveying end of the stock base conveying device 16, that is, the adjusting portion 19 b of the clamping rod 19 (see D in the same figure). At this time, the tip part is already attached to the locking body 24.
Although the waste straw is located in contact with the starting end of the waste straw passage 7, it falls and is supplied to the starting end of the waste straw passage 7 while drawing a fan-shaped trajectory centering on the tip of the ear. (dashed line).

Therefore, the stem part of the waste straw is held at a fixed position in the waste straw passage 7 by friction and is allowed to fall centering on the tip part where there is no risk of movement. They are supplied in a state in which they are arranged in approximately the same position, and by the bundling operation described below, it is possible to obtain extremely good bundled waste straw with the roots aligned.

In this way, the waste straw supplied to the starting end of the waste straw passage 7 with the stock end facing the harvested side is pushed as it is by the packer 10 to the terminal end of the waste straw passage 7, and a certain amount When the waste straw is received by the door 13, the collected waste straw is bundled by the action of the knot part 8, and the bundled waste straw is discharged from the end of the waste straw passage 7 opened by opening the door 13 and released from the arm 9. Due to the cooperative action of this and the resistance rod 15, the attitude is changed toward the mown field, and then the mower is released.

At this time, since the waste straw binding machine 6 is installed close to the combine harvester 1, the waste straw passage 7 is extremely short, which means that the waste straw is only transported over a very short distance by the packer 10. Therefore, there is no problem that the posture of the straw is disturbed while it is being transferred by the packer 10, and the straw can be obtained as a good result by aligning the roots of the straw, and there is no resistance to change the discharge posture. Since the resistance action of the rod 15 is not received by the soft tip part as in the conventional case, but by the firm base part, the effect of changing the ejection posture can be performed more reliably and better.

Therefore, the combine harvester with a waste straw tying machine according to the present invention can perform a good tying operation by first transporting the waste straw in the direction of the harvested side by the side conveying device 16, 17 and then supplying it to the waste straw tying machine 6. However, since the two conveying devices 16 and 17 are arranged along the width direction of the combine 1, the two conveying devices 16 and 17 are
．． Due to the presence of 17, the combine 1 of the waste tying machine 6
The device can be installed close to the device, the overall length can be shortened as much as possible, and the device can be constructed compactly.

Moreover, since the overall length can be made compact in this way, the front-rear balance becomes more stable, and the combine harvester equipped with a waste straw tying machine can always run in a stable state and in good condition.

In the case of a combine harvester with a waste straw binding device, the driver's seat is located on the harvested side and the left-right balance is tilted toward the harvested side, but as in the above embodiment, the transmission case 14 is arranged on the uncut side. By doing so, the left and right balance will be stabilized and the above effect will be even more pronounced.

Further, as in the above embodiment, by making each of the levers 19 and 22 adjustable for expansion and contraction, that is, both conveying devices 16.
By making the conveyance end position of the combine harvester 17 adjustable in the width direction of the combine 1, the amount of waste straw transferred in the direction of the cut side can be changed as appropriate. It is convenient to be able to appropriately change and adjust the binding position of the bundled waste straw without the need for troublesome work such as moving it in the width direction of the combine and a complicated mechanism for that purpose.

Furthermore, the binding position can be changed to a wider range than the conventional one, which is advantageous.

In addition, in the above embodiment, an example was shown in which the attitude changing means is configured by the straw guiding passage 4 and the straw guiding plate 5 built into the lower-class combine harvester 1. It goes without saying that this can also be applied to a top plate type combine harvester, and it is also possible to configure the posture changing means only with a guide plate or a guide rod having a shape that can perform the same function as the guide plate 5 described above. This may be installed on the rear wall 1b of the combine harvester 1 or on the body of the waste straw binding machine 6.

Further, the straw binding machine 6 does not have to have the transmission case 14 disposed on the uncut side as in the above embodiment, but may of course be of a conventional type with the transmission case disposed on the already cut side. However, if the transmission case 14 is placed on the uncut side as in the above-mentioned embodiment, it is a theory that it can be used for cross-feeding. Since the tip portion on the uncut side can also be locked by the transmission case 14, there is no need to provide the tip locking body 24, which is convenient.

Furthermore, as in the above embodiment, if the conveying speed of the auxiliary conveying device 17 is set lower than that of the stock conveying device 16, the difference in conveying speed between the two conveying devices 16 and 17 causes the removed straw to be placed in an inclined position. It is obvious that this can be done, and it goes without saying that there is no need to provide the tip locking body 24 in this case as well.

In connection with the above, the stock head conveyance device 16 and the auxiliary conveyance device 17 are driven to rotate at the same speed, and the tip locking body 24
Even if the transmission case 14 is not arranged on the uncut side, both the conveying devices 16
, 17, the tip of the straw is always secured to the uncut side end of the member constituting the lower surface side of the straw passageway 7, and the tip of the straw is fed horizontally by the straw removal channel 7. It is clear that posture is influenced by posture.

Therefore, in the combine harvester with waste straw binding device according to the present invention, it is not an essential requirement to provide a locking means corresponding to the ear locking body 24.

In any case, as can be easily understood from the above explanation, the combine harvester with a straw tying machine of the present invention has the same effect as the conventional one, that is, the waste straw discharged from the combine is temporarily moved in the direction of the harvested side. Although this device has the effect of being able to transport the waste straw to the harvester and then supply it to the tying machine, both the stock-head conveying device and the auxiliary conveyance device for conveying the waste straw in the direction of the harvested side do not have the same width as the width of the combine harvester. Since it is arranged along the direction, the waste straw binding machine can be installed close to the combine harvester, and therefore it can be constructed as a compact device with the overall length as short as possible, and it is always stable. It is possible to run the vehicle well even in the same condition.
