Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a harvester for harvesting beans such as edamame beans.

[0002]

As a harvester capable of harvesting beans, for example, as disclosed in Japanese Patent Publication No. 56-169515, a crop planted in a field is sandwiched by a pair of left and right chains and rearward and upward. It is known that the crop is pulled out along with the roots and transported, and the roots are cut off during the transportation. Further, as a technique that can be used for pulling and harvesting crops, as disclosed in Japanese Patent Laid-Open No. 7-59424, a crop planted in a field is clamped by a pair of left and right belts and conveyed backward and upward. While pulling out the roots and transporting them, guide the transported crops between the left and right spiral rolls or between the conveyor belts with protrusions on the left and right to convey them upward and backward, and put them into a chopper to shred them. The composition is known.

[0003]

[Problems to be Solved by the Invention] The former (Japanese Patent Publication No.
No. 69515), the roots of the withdrawn crops are cut off, so that the recovered crops may be inconvenient for depodization. In other words, as a means for decapsulating the collected crops, the crops are inserted into the decapsulator and hit by the claws protruding from the rotating drum to separate the pods from the stems. It is necessary to grab the root and insert it into the decapsulator, and the root of the crop needs a gripping part without a pod. Here, the leg of the legume grows branching from the root to the root, so if you cut off the root, you will lose the part without the pod, and if you just put it on the decapsulator, the root part of the crop will be removed. However, it was impossible to insert the pods sufficiently, and a processing residue was generated, which required a separate treatment to collect the remaining pods.

The latter (JP-A-7-59424)
Although the plant harvests the crops with roots, it does not consider the recovery process after the harvesting, and it requires further devising to enable the harvest of beans.

The present invention has been made by paying attention to such a point, and provides a harvester which is suitable and efficient for harvesting beans, and is excellent in handleability. Is the main purpose.

[Recovery Transport Section 60]

The recovery transporting unit 60 merges and transports the two crops W that have been pulled out and transported by the left and right pulling and pinching and transporting devices 11 by the left and right rear transporting means, and sends them to the recovery platform 70 described later. Each of the left and right rear transport mechanisms has a lower holding transport device 61L, 61R.
And the upper locking transfer devices 62L and 62R.

Each of the lower sandwiching and conveying devices 61L and 61R constituting the left and right rear conveying means is composed of a resin-made chain 63 with a protrusion and a sandwiching rail 54 facing the chain 63. It is arranged in parallel with the pull-out and nip transport device 11 in a side view.

The right upper locking transport device 62R comprises a belt 66 with a claw integrally formed with a locking claw 65 and a transport guide 67 arranged along the movement path of the claw tip.
It is arranged in parallel with the locking and pulling and carrying device 11 in a side view from just above the terminal end of the locking and pulling and carrying device 12 on the right side. The transport guide 67 is an extension of the transport guide 23a of the locking and pulling transport device 12 on the right side. On the other hand, the left upper locking transport device 62
L is configured such that the locking and pulling and conveying device 12 on the left side is linearly extended rearward.

Here, the lower sandwiching and conveying device 61R and the upper locking transporting device 62R on the right side are arranged so as to be inclined in a plan view so that their rear parts approach the lower sandwiching and transporting device 61L and the upper locking transporting device 62L on the left side.

Is arranged, and the crop W sent out from the transport outlet E is guided by these guide rods 68 and 69, and the root Wn thereof is discharged in a sideways posture facing the driving section C side. ing.

Further, the conveying speed of the right upper locking conveying device 62R is set to be higher than the conveying speed of the right lower sandwiching conveying device 61R, which promotes the crop delivery in the sideways posture.

[Recovery stand 70]

The recovery stand 70 is for receiving and collecting the crop W discharged in the sideways posture from the transfer outlet E of the recovery transfer section 60 as described above, and also digs under the recovery transfer section 60. Thus, the front half portion is inclined to the forward rising posture to prevent the collected crop W from spilling forward, and the rear half portion on which the crop W is placed is configured to be substantially horizontal. Then, when an appropriate amount of the crops W is collected on the collection stand 70, the driver or the auxiliary worker collectively leaves the crops W on the collection stand 70 on the ground. In this case, since the front half of the recovery stand 70 is inclined forward and upward, it is easy to collectively scrape the crops W on the recovery stand 70 from the front to the rear, and the rear half is substantially horizontal. , It is possible to release it to the ground simply by scraping it without lifting the scraped crop W.

The left end portion 70a of the recovery table 70 is slidable to the left and right, so that the recovery table 70 can be stored narrowly and narrowly when no work is performed.

The green soybean harvesting machine according to the present invention is constructed as described above, and by traveling forward over the multi-ridged ridges U, the two crops (edamame) W planted are collected without exception. The roots Wn are pulled out, the crops W that have been pulled out are conveyed backward and upward, the root Wn is soiled, and the roots Wn are merged on one side of the machine (left side in this example), collected sideways, collected, and left on the ground together in appropriate quantities. You can do it.

[Other Embodiments] The present invention can also be implemented in the following modes.

As shown in FIG. 17, the recovery transport unit 6
By disposing the scraping rotator 82 having the locking claw 81 on the upper end of the left side upper locking transport device 62L at 0, the merged crops W can be more surely laid down and sent out. Will be things. As shown in FIG. 18, the right upper locking transport device 62R in the recovery transport unit 60 is replaced with the lower holding transport device 61.
By arranging the crop W so as to project it to the transport outlet E side rather than R, the crop W can be surely laid down and sent out. As shown in FIG. 19, left and right pull-out and nip transport devices 1
By oscillating and adjusting the 1 and the left and right locking and pulling and conveying devices 12 to the left and right around the rear side, the starting end position of the pulling and conveying route in the pulling and pinching and conveying device 11 can be adjusted left and right. It can correspond to the left-right spacing of crop rows. In this case, by configuring the rear drive wheel 2 and the front idler wheel 3 so that the left and right positions can be adjusted, it becomes possible to run a single-row planted ridge across two ridges and perform two-row harvesting.
