Next, its effect will be explained.

In the plan view shown in Fig. 1, with the left side, that is, the side where the lifting chain case 8 is located, aligned with the growing edge of the rush, start the engine 4, operate each part, and move the aircraft. If 1 is run, the straw whose stem part is branched by divider 7 will be distributed to the rod 1 following the same divider 7.
Due to the vibration action in step 4, the parts above the stems that are intricately intertwined with each other are branched without damaging the intervening parts, and the one to several strands of grass that are branched in this way are pulled up one after another. Therefore, it is introduced into the passageway 10.

One to several lines of grass introduced into the passageway 10 in this manner are forcibly pulled up through the raising claws 9 and sent backward through the passageway 10. At the same time, the stem portion is cut off by the cutting blade 12.

The straw grass whose stems have been cut off as described above is placed in Star Foil 13.
is sent to the direction of the conveyance port 15' of the main conveyance belt 15 through the conveyance belt 16, 1 of the main conveyance belt 15, and the vicinity of the tip of the
6', and is conveyed diagonally backward in such a sandwiched state.

However, as described above, the main conveyance belt 15 is
The lower end of the straw that is clamped by the straw grass is completely free and transported in a suspended state, but during the transport process, the lower end of the straw is first transferred to the primary screwing device 18. It will be a collision.

The straw that has hit the primary pickling device 18 is continuously struck at its lower end by the circulating picking claws 20, and is shaped into a substantially fan shape in a direction substantially perpendicular to the transport direction. The short culms, that is, the parts near the upper ends of the short culms that are not held between the main conveying belts 15 and are merely entangled between the individual straw plants, are removed.

The rush that was subjected to the first cursing in this way was
The second scoring device 21 performs the scoring again.

That is, for the rush that has finished the first rounding as described above, the picking claws 23 of the second rounding device 21 enter the vicinity of the upper end of the rush every few minutes, and As if combing the hair, a slit is made from the area near the top toward the bottom to remove the waste grass.

In addition, when the second rounding is performed by the rounding claw 23 as described above, the lower end of the rush is carried through the rounding claw 23 in the width direction of the machine body 1, that is, to the tip of the chain case 22. In this way, the lower end portion of the rush that has been conveyed to the tip of the chain case 22 and released from the scooping claw 23 is transferred to the main conveyance belt 1 again through its gravity.
There is an effect of trying to return to the direction directly below 5.

In this way, when the rush tries to return directly below the conveyance belt 15, its lower end portion hits the auxiliary conveyance belt 24.

The lower end portions of the rushes that hit the auxiliary conveyance belt 24 are sequentially engaged with the feed claws 27 of the auxiliary conveyance belt 24 and are conveyed in the same direction as the main conveyance belt 15.

In this way, the lower end portion of the rush that was engaged with the feed pawl 27 of the auxiliary conveyance belt 24 and conveyed in the backward direction was not completely scraped off during the second scour. The fallen grass is engaged with the star wheel 28 and sent towards the pair of rollers 29, 29'15.
A third round of finishing is carried out.

That is, the above-mentioned waste grass sent in the direction of the pair of rollers 29 and 29' is bitten into the notches 31 and 31' while being engaged with the star foil 28, and is forcibly pulled out. It is squeezed between the rollers 29 and 29' and is also forcibly discharged.

In this way, at the same time that the first to third scoring is completed, the material is released from being held by the main conveyance belt 15.

The straw grass released from the main conveyance belt 15 in this way is now supported by the spiral feeding rod 33 near its upper end, and its lower end is sequentially transferred into the bundling device 32 via the packer. Once the amount reaches a certain level, it is bundled and released outside the aircraft.

The present invention has the above-described configuration, and in the process of conveying the cut rush grass in a diagonally backward direction while holding it between the main conveyance belts 15, the first step transports the stem portion of the rush grass in the horizontal direction.
Next, the first cutting is carried out by spreading it out into a fishing net shape through the cutting claw 20, and the second cutting claw 23 is used to send the rush from the tip of the rush toward the stem in an oblique manner to the rush. By scraping it off in a comb-like manner and performing the second rounding off, short culms entangled in the straw can be sorted out and eliminated very quickly, easily, and accurately. It can be done.

In addition, in the present invention, the secondary countersink 20 is provided so as to be fed in an acute angle direction with respect to the main conveyor belt 15, and at the rear of the secondary countersunk claw 20, a lower part of the main conveyor belt 15 is provided. By providing an auxiliary conveyance belt 24 along the line, the stem part of the rush that has been released from the second cutting claw 20 after the second cutting process is
In the process of returning to the previous position, the feed pawl 27 of the auxiliary conveyance belt 24 can be properly engaged, and the stem can be smoothly guided in the direction of the subsequent hemming device. .
