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 aim is to ensure that the product can be supplied to a large number of people, thereby ensuring a good binding 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 and the straw tying machine, so the straw tying machine is placed close to the combine. This had the disadvantage that it could not be attached, resulting 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 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 transferred to the combine side or the waste straw tying machine side by the foot chain. A means for changing the posture of the straw when brought to the terminal end of the straw binding machine is provided to change the posture of the straw to a substantially hanging posture in which the tips of the straw are directed downward. A stock transport device is disposed above the starting end and has a transport path extending from a portion near the end of the foot chain toward the cut side by an appropriate amount along the width direction of the combine harvester, and It is located at a position below the starting end of the device and biased from the side wall of the combine harvester by an appropriate amount toward the cut side, and the stock head portion is transferred from the foot chain to the stock head conveying device and transferred to the cut side. A combine harvester with a waste straw tying device is characterized in that it is provided with a tip locking body that locks the tip of the waste straw in the conveyance direction.

Next, 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 this combine harvester 1, the attitude of the husks discharged from the combine 1 and brought to the end of the foot chain 2 is changed to a substantially hanging attitude with the tips facing downward. A means for changing the posture is provided to maintain the position.

That is, a vertically elongated straw guide passage 4 facing outside the combine 1 from a portion near the end of the handling barrel 3 along the side wall 1a is formed in the combine 1, and the starting end of the four straw straw guide passages 4 and the handling A straw guide plate 5 is provided which is inclined rearward and downward from the terminal end of the trunk 3 and in the direction of the straw guide passage 4, and the straw guide plate 5 is arranged so that the straw guide plate 5 is inclined rearwardly and downwardly from the end portion of the trunk 3 and in the direction of the straw guide passage 4. The tip portion of the waste straw to be transferred is guided from the end of the handling cylinder 3 to the waste straw guide path 4 while gradually changing its posture downward by a waste straw guide plate 5.

That is, the foot chain 2 allows the waste guide path 4 to be
The waste straw discharged from the end of the combine outside the combine 1 is
The posture has been changed to a substantially hanging position with the tip 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 nodal part 8 and has a packer 10 and a needle 11 on the lower side.
A door 13 is provided at the end of the straw removal path 7, and the knot portion 8 and the converging portion 12 are fixedly supported in a cantilevered manner by a transmission case 14 disposed on the uncut side. The construction and operation are different from the usual one except that the knot part 8 converging part 12 and the transmission case 14 are arranged in one device with the right and left sides reversed from the usual one. It's something that doesn't exist.

In addition, 15 applies a certain resistance to the part of the bundled and removed straw that is closer to the already cut side than the part that is receiving the action of the discharge arm 9 during the action of releasing the bundled and removed straw. This is a resistance rod for changing the straw discharge attitude toward 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 rotates in the A direction on a horizontal plane. A stock head conveyor belt 18 configured to be driven, and a pipe-shaped fixed portion 19a provided opposite to the starting end side portion of the stock head conveyor belt 18, and a rod-shaped rod-shaped portion opposite to the terminal end side portion of the stock head conveyor belt 18. The fixing part 1 is configured with a clamping rod 19 that is fitted into and supports the adjustment part 19b of the fixed part 1.
The length of the clamping rod 19 can be adjusted via a set screw 20 screwed onto the stock head 9a, and therefore the length of the conveying path of the stock conveying device 16, that is, the conveying end position can be adjusted. ing.

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, and the fixed part 22a The length of the conveyance path can be adjusted via a set screw 23 screwed into.

The auxiliary conveyance belt 21 is driven to rotate in the same direction (direction A) as the stock conveyance belt 18 at the same speed.

The length of each clamping rod 19, 22 is always the same as that of the auxiliary conveyor 17.
The end of the conveyance is set to be located a certain amount closer to the uncut side than the end of conveyance of the stock transfer device 16.
The lengths of 9 and 22 are also adjusted as appropriate within a range that satisfies these conditions.

The auxiliary conveyance device 17 is located at a position below the starting end thereof and offset by an appropriate amount from the side wall 1a of the combine harvester 1, that is, in this embodiment, the height is approximately aligned with the lower end surface 7a of the straw removal passage 7. transmission case 1 in the
4, and a rod-shaped tip locking body 24 is positioned at a position slightly closer to the convergence part 12 than the rear wall 1b of the combine harvester 1.
Further, the tip of the tip locking body 24 is bent upward, and the pinching rod 19 is attached to the bent portion 24a.
, 22, that is, the fixed portions 19a, 22a are connected to 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 its base by the foot chain 1 and transferred to the combine harvester 1.
When the straw is ejected from the container, it is in a substantially hanging position with its tip facing downward via the attitude changing means, that is, the ejected straw guide plate 5 and the ejected straw guide path 4 (FIG. 3A).

When the waste straw is brought to the end of the foot chain 2 in this position, the base part of the straw is brought to the end of the foot chain 2.
is transferred from the terminal end to the start end of the stock transport device 16 and the auxiliary transport device 17, and is transferred in the width direction of the combine 1 by both transport devices 16, 17.

As the ears are conveyed along the cut side (direction A) and the tip portion is locked by the ear locking body 24, the tip portion gradually becomes retarded in the conveyance direction (direction A). Posture changes.

(Fig. 3B) Furthermore, the straw is transferred in the direction of cutting by both of the conveying devices 16 and 17, with the attitude of the straw becoming inclined toward the horizontal. It comes off from the conveying end of the conveying device 17, that is, the adjusting portion 22b end of the clamping rod 22 (FIG. C), and then comes off from the conveying end of the stock source conveying device 16, that is, the adjusting portion 19b end of the pinching rod 19 (FIG. 1C). D), but at this time the tip is still attached to the locking body 24.
1 and will not slip down toward the mouth, the waste straw will move to the starting end of the waste straw passage 7 while drawing a fan-shaped trajectory centering on the tip of the ear that is stopped by the locking body 24. (dashed line in the same diagram).

Therefore, the waste straw is supplied to the starting end of the waste straw passage 7 with the base ends of the plants aligned at substantially the same position.

Then, the waste straw supplied to the starting end of the straw passage 7 with the tip thereof being locked to the locking body 24 is pushed as it is into the terminal end of the waste straw passage 7 by the packer 10. However, at this time, the soft tip is attached to the locking body 2.
4, the bending portion 24a is passed smoothly.
The presence of ``a'' does not hinder the transport of waste straw by the packer 10 in any way.

Rather, by imparting a slight resistance to the tip of the ear using the bent portion 24a, the balance of running resistance with the stock, which has a larger running resistance against the lower surface of the straw channel 7 than the tip due to its volume, can be improved. This makes it possible to push the waste straw into the terminal end of the waste straw passage 7 with a good constant posture that does not cause the stock to lag.

Furthermore, 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, a certain amount of waste straw can be received at the door 13 with its roots aligned, without causing problems such as the attitude of the waste straw being disturbed while being transferred by the packer 10.

Therefore, the collected waste straw received by the door 13 can be well bound by the action of the knot 8, and the bundled waste straw is discharged from the end of the waste straw passage 7 opened by the opening movement of the door 13 by the arm. Due to the cooperative action of 9 and the resistance rod 15, the posture is changed to the already-cut side, and then it is released.

At this time, the resistance action of the resistance rod 15 for changing the ejection posture is not applied to the soft tip part as in the conventional case, but to the firm base part, so that the effect of changing the ejection position is increased. can be carried out reliably and efficiently.

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 cut side by both the conveying devices 16 and 17 and then supplying it to the waste straw tying machine 6. However, since both the conveying devices 16 and 17 are arranged along the width direction of the combine harvester 1, the both conveying devices 16 and 17 are arranged along the width direction of the combine harvester 1.
．． Due to the presence of 17, the waste tying machine 6 can be combined with the combine harvester 1.
The overall length can be made as short as possible, making it possible to construct a compact device.

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.

In addition, as in the above embodiment, by making each of the clamping rods 19 and 22 adjustable for expansion and contraction, in other words, both conveying devices 16.1
By making it possible to change and adjust the conveyance end position of 7 in the width direction of the combine 1, it is possible to change the amount of waste straw transferred in the direction of the harvested side 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, the attitude changing means is built into the lower-grade combine harvester 1.

Although an example has been shown in which the configuration includes the guide passage 4 and the straw guide plate 5, it goes without saying that such attitude changing means can also be applied to an upper board type combine harvester, and the attitude changing means can be configured by using the guide plate 5. 5 It is also possible to construct the system using only a guide plate or a guide rod having a shape capable of performing the same function, and this can be arranged on the rear wall 1b of the combine harvester 1 or on the body of the waste straw binding machine 6. It's okay to be there.

Further, in the above embodiment, the ear locking body 24 is made of a rod-like body and is fixed to the rear wall 1b of the combine harvester 1. It may be provided in advance or a part of the body may be used, and its shape may be arbitrary. It is sufficient if it has the function of locking.

Further, the auxiliary conveyance device 17 in the above embodiment does not necessarily need to be provided, and the straw tying machine 6 does not have the transmission case 14 disposed on the uncut side as in the above embodiment. Of course, it is also possible to use a conventional type in which the transmission case 14 is placed on the cut side, but if the transmission case 14 is placed on the uncut side, the tips of the ears of straw when being fed sideways can be Since the part can also be locked by the transmission case 14, it is possible to use a part of the transmission case 14 as the tip locking body without providing the tip locking body 24. It's convenient.

In any case, as can be easily understood from the above explanation, the combine harvester with a waste straw tying device of the present invention is provided with a posture changing means, a stock head conveying device, and a head locking body, respectively.
The waste straw discharged from the combine harvester is once transferred along the width direction of the combine toward the cut side, and then fed to the waste straw passage of the waste straw binding machine with the stem of the straw facing toward the cut side. Therefore, the presence of a stock conveyor installed along the width of the combine does not prevent the straw binding machine from being attached close to the combine. It is possible to construct a compact vehicle whose overall length can be shortened as much as possible, and it has the advantage of being able to run smoothly with a stable front-rear balance at all times.

Moreover, since the combine harvester with a waste straw tying machine of the present invention has the combine harvester and the waste straw tying machine close to each other as mentioned above, it is possible to shorten the amount of waste straw transported by the waste straw passage, that is, the packer, and to reduce the amount of waste straw that is transferred by the packer. It is possible to condense the waste to the binding position at the end of the passage without any disturbance, and to always perform a good binding operation.

In addition, in the combine harvester with a waste straw tying machine of the present invention,
When the waste straw is dropped and supplied from the stock transfer device to the waste straw passage, it falls in a fan-shaped trajectory centered on the tip, which is always locked by the tip locking body and does not move (i.e., (The head of the plant is dropped in a fan shape with the tip supported by a locking body.) Therefore, when the culm falls, there is no disturbance to the culm, and the waste straw supplied to the straw passage is always maintained. The husks are supplied without any disturbance and with their roots aligned, so that the transporting action and bundling work by the packer can be carried out extremely well, and it is possible to obtain extremely good bundled waste straw.

Furthermore, since the culm is dropped in a direction perpendicular to the direction in which the packer is raking, and the lower part of the conveyance path is used as a focusing path, a binding machine can be approached and attached.

Due to the fan-shaped fall conveyance, the straw layer becomes coarse (thin) at the horizontal position of the fall, making it easier for the packer to clog, and has the effect of preventing clogging only at the nodule entrance.
