DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-removable combine grain stalk feeding apparatus for feeding stalks, such as stalks, high-cut stalks, soybeans or buckwheat, and threshing from a stock plant. .

[0002]

2. Description of the Related Art Conventionally, a thresholder type combine and a self-removing type combine have already been known.

[0003]

In the known combine, the thresher-type combine harvester puts all the cutted material into a handling room and threshes it, so that the grain is relatively close to the root of the stock, such as buckwheat or soybean. Even if threshed is adhered, there is no untreated residue. Further, when cutting and threshing relatively long culms, the headland can be cut high and thrown into the supply port, so that the hand-cutting and hand-handling work at the headland can be omitted. However, grain culm,
In particular, when threshing is performed on a tough culm such as a rice culm, the resistance to the handling cylinder is significantly increased and the threshing performance is reduced. In addition, since the self-removing type combine performs threshing by inserting only the tip portion into the handling chamber while nipping and conveying the stock side of the threshing target object by the feed chain and the clamping rail,
When threshing cereals such as rice and wheat, threshing resistance is extremely small, and threshing performance is high. However, if buckwheat or soybeans are to be threshed, the roots of the stock are conveyed, so that the grains attached to the base of the stock are left untreated.
Therefore, even though the threshing resistance is small, even if threshing the soba or soybean, there is no unhandled residue,
In addition, a combine that does not require hand cutting on the headland is desired.

[0004]

The tip supply chain 33 has a front portion that inherits the spike side of the grain culm conveyed near the rear end revolving portion of the tip conveyance body 2, and the rear end portion is a side view. As shown in FIG. 3, it extends to a position overlapping with the rotation locus of the spiral body 25 of the front body 6a. As shown in FIG. 2, the stock supply chain 30 is parallel to the feed chain 8 and the tip supply chain as shown in FIG. Reference numeral 33 denotes a front end located forward of the handle barrel shaft, while a rear end inclined to face the front side of the truncated cone of the front body 6a. The transport speed V2 of the chain 33 is the stock supply chain 3
0 is higher than the transport speed V1.

The conveying speed of the tip supply chain 33 and the raking claws 31... Pitch will be described. The conveying speed and the pitch are controlled by the two raking claws 31 during the rotation of the front body 6a. I do. That is, since the front body 6a has the two spirals 25, while the front body 6a makes a half turn, one of the scraping claws 31 is at the rear end circling portion and the spiral body 2 is rotated.
The spike side of the cereal stem that has entered and locked and transported between the front portions 5 and 25 is delivered.
When rotated, it interlocks with the front trunk 6a so that the spikes of the grain stalks that have been conveyed to the other gaps in front of the two spirals 25, 25 are pushed in while rotating and delivered. In addition, the pitch of the scraping claws 31... Is set.

With the above-mentioned configuration, when the machine is put on the headland to cut and thresh grain culm such as rice and wheat, the rear portion of the grain culm transport device 4 is moved by a manual switch to the tip side.
To the deepest handling position.
The sensor S provided inside the rear end of the transmitter 3 is turned on,
This detection result is input to a control device consisting of a microcomputer,
After a predetermined time, the above-mentioned speed change lever 23 is switched at a high speed, and then the pre-processing device is raised and tilted to perform the mowing posture, and the harvested cereal culm is sent backward by the cereal culm conveying device 4, and the conveyance end thereof. In the section, the stock-side end portion is passed from the rear end of the stock-holding / conveying body 3 to the front end of the stock-source supply chain 30 and further fed back. 33 are passed on to the entrance plate 28 at the tip thereof.
It is sent back in a state where it does not leak to the upper surface of the culm.
At that time, the base of the raking claw 31 rises and protrudes at the front end by a guide rail in the chain case 32 in the same manner as the cereal culm raising body in the rubbing operation stroke, and locks and conveys the ear side of the cereal culm, At the rear end, after turning upward, the guide rail is released and the front rail is rotated forward in a rearwardly lying posture where the regulation is released,
The spike side locked and transported at the rear end circling portion is forcibly supplied between the spiral bodies 25 of the front body 6a.

Is not passed on to the chain 8
Can be supplied into the handling chamber 5 for threshing.

As the cutting of the headland progresses, the pretreatment device is sequentially lowered, and immediately before the entire crawler enters the field, the adjustment of the handling depth is set to automatic control . The sensor S is turned off since the sensor S is turned off by moving to the base of the stock from the deepest handling position and performing the shallow handling adjustment operation, whereby the speed change lever 23 is switched to a low speed after a predetermined time, and the rotation of the handling cylinder 6 is reduced to a low speed. In other words, grain culms harvested from the root are threshed by a self-removal method. At this time, since the stock portion that has been sent back by the stock supply chain 30 is transferred to the feed chain 8 while being pinched and conveyed, the handling room 5 has grains containing some culm and leaf debris. Only and the threshing resistance is smaller than in the state where the culm is also inserted,
A sufficient threshing process can be performed at a normal rotation speed (low-speed rotation in this example) of the handling cylinder 6. If the pretreatment device approaches the ridge at the end of the cutting in one stroke, the pretreatment device is sequentially raised to cut the pillow while the pillows are being cut while preventing the weeds from colliding with the ridge, and the grain culm is manually switched. When the conveying device 4 is deeply handled and the sensor S is turned ON, the cereal culm on the stock supply chain 30 at the time of detection rotates the handling drum 6 at a high speed after a predetermined time after the supply, and the grain culm that has been ear-cut is removed. The whole amount is put into the handling room 5. When cutting and threshing buckwheat and soybeans, the culm conveying device 4 is set to the deepest handling position , and the cutting cylinder 6 is rotated at a high speed to perform the cutting and threshing operation, similarly to the above-described cutting and threshing of the headland. . Further, in any of the threshing processes, the rear trunk 6b is rotated at a higher speed than the front trunk 6a, so that the threshing process can be performed at a higher level.

Although illustration and description are omitted, the handling room 5
A rocking sorter that swings back and forth is installed in the sorting air passage extending from below to the rear dust sorting chamber as in the conventional threshing machine,
Threshing is sieved and first-sorted into first and second ones.
