Hereinafter, an example is described concretely based on a drawing.
First, the general-purpose combine of this application is manufactured mainly for harvesting sunflowers. As shown in FIGS. 1 and 2, the general-purpose combiner mounts the threshing device 2 on the chassis 1 equipped with a pair of left and right crawlers 18 with the supply unit 6 on the front side, and is conveyed to the supply unit 6. The conveyor chamber 10 is connected to the conveyor terminal 9 facing the transfer terminal portion. In the embodiment, as shown in the drawing, the transfer conveyor device 9 is mounted in a conveyor chamber 10 and pivoted freely, with the transfer end portion facing the supply portion 6 of the handling chamber 3, and the transfer start end portion. Is provided so as to face the back of the front auger 8. As shown in FIG. 1, the conveyor device 9 has a configuration in which the drum 20 at the conveyor start end portion is provided with a scraping finger 21 similarly to the scraping auger 8 so as to reliably scrape the flower portion of the sunflower. Yes.

  As shown in FIG. 1, the threshing device 2 has a handling chamber 3 in which a handling cylinder 5 is pivoted in the front-rear direction and a sorting receiving net 14 is stretched on the lower side. Is provided with a sorting chamber 22.

  As shown in the drawing, the handling cylinder 5 is formed with a spiral cylinder 4 on the front end side in front of a portion that maintains a parallel state with the lower sorting receiving net 14, so that the sorting receiving net of the handling chamber 3 is formed. 14 is provided so as to project forward from the front end edge of 14, and a space portion is formed in a lower portion thereof to form a passing space portion 15. And in the case of an Example, the inheritance space part 15 is set as the structure which has arrange | positioned the conveyance termination | terminus part of the said conveyance conveyor apparatus 9 in front of the front side so that it may understand from a drawing.

  Therefore, after the conveyed product reaches the terminal end portion of the conveying combiner device 9, it is further moved while receiving the conveying pressure of the succeeding sunflower groom sent from the front side, and the spiral of the spiral cylinder 4 acts directly. It reaches the vicinity, is scraped, inherited, and sent into the handling chamber 3 from the supply unit 6 of the handling chamber 3.

  Next, as shown in FIG. 1 and FIG. 2, the dust suction fan 11 is disposed at an upper position in the middle of the conveyor chamber 10, and absorbs dust between the chamber 10 and the handling chamber 3. In this configuration, dust is discharged to the side. As shown in FIG. 1, the dust-absorbing wind guide plate 12 and the conveyed product guide plate 13 have a function of guiding and guiding the dust-absorbing wind on the upper surface, and guide and guide the conveyed product on the lower surface so as to be pressed against the conveyor device 9. It is formed in a downward shape, and is attached to a portion of the dust-absorbing fan 11 that is close to the handling chamber 3 side.

  Therefore, the dust-absorbing air guide plate 12 guides the dust-absorbing air to the upper dust-absorbing fan 11 and reliably assists the sucking of air, while disturbing the conveyed object being conveyed by the lower conveying conveyor device 9. There is a feature that dust can be guided accurately without any flow. In this case, the dust suction range is characterized in that the dust suction fan 11 also works on the starting end portion of the handling chamber 3 connected to and communicated with the rear portion of the conveyor chamber 10 to appropriately absorb the floating dust. is there. In particular, since sunflower seeds have a low specific gravity, it is known that when the dust-absorbing wind is weakened, the seed husks are mixed into the first thing. Therefore, the dust suction wind guide plate 12 is provided so that the dust suction wind does not weaken and does not adversely affect the conveyed product and can perform the necessary dust suction action.

  And the conveyed product guide plate 13 forcibly guides the conveyed product to the conveying conveyor device 9 side, and eliminates the adverse effect on the conveyed product by the dust suction air. There is a feature that can guide to the start side.

  Next, unlike the configuration example described above, the embodiment shown in FIG. 3 drives the rotation of the dust-absorbing fan 11 in the reverse direction to feed the compressed air into the conveyor chamber 10 and eject it toward the handling chamber 3 side. It is configured. And as shown in FIG. 3, the inclination board 25 is set as the structure which can convey by flowing a pressurized wind to the conveyance conveyor apparatus 9 side. Therefore, in the case of the embodiment, as shown by the arrow in FIG. 3, the conveyed product is forcibly sent to the handling chamber 3 side under the action of compressed air, and the light seed is also sent together. For this reason, the embodiment has the advantage that damage particles and loss are reduced, and the contamination is first mixed in, and the sorting accuracy is improved.

  Next, as shown in FIGS. 1 and 2, the pre-cutting processing device 26 is provided with a collection table 27 connected to the conveyance start end of the conveyor chamber 10, and the horizontal axis 28 is placed on the table 27 in a horizontal direction. A stirrer auger 8 pivoted on the base is provided. Then, as shown in the drawing, the pre-cutting processing device 26 is provided with the cutting device 7 on the front side of the collection table 27, and the flower portion (seed portion) of the sunflower on the upper side of the stem is cut by the cutting device 7 as described above. The take-in auger 8 is configured to supply to the transfer start end of the conveyor chamber 10 while collecting in the transfer process.

  The cutting pretreatment device 26 configured in this manner cuts the floret portion at the top of the sunflower and collects it with the driving auger 8 while moving forward with the cutting device 7 set at the high cutting position, It supplies to the conveyance start end part. Then, as already described, the flower part of the sunflower is transported through the conveyor chamber 10 by the transport conveyor device 9 and supplied to the handling chamber 3 for threshing.

Next, an embodiment of the stalk guide bar 30 used during the sunflower harvesting operation will be described.
As is widely known, sunflowers have a large floret part formed by seeds gathered at the top of a long pedicle, and this floret part is targeted for harvesting, and the shoot part is also collected separately. Processing such as extraction of bioethanol.

  However, the conventional general-purpose combiner often harvests the long stalks of the sunflower by the scraping reel 31 on the front upper part and cuts them together with the long stalks and supplies them to the threshing device. There was a difficult task.

  First, as shown in FIGS. 4 and 5, the stalk guide bar 30 is connected to the front end portions of the left and right reel arms 32 and 32 supporting the take-up reel 31, and the front side of the take-up reel 31. It is configured as an integral bar that bypasses

  The stem-and-rod guide bar 30 configured in this manner advances while being pushed forward from the middle part of the sunflower stem to the front side as the vehicle body 1 advances, and the contact position sequentially moves to the upper part, and the lower rear cutting device The neck part of the long pedicle reaches 7 and is cut off. Then, when the sunflower groom is cut, it rests on the collection table 27 and is scraped into the scraping auger 8 side. In this way, the floret part reaches the threshing device 2 via a series of conveyance paths and is threshed, but at that time, the excessive stem portion is short, so the threshing load is greatly reduced. As well as improving the sorting accuracy. Further, as shown in FIG. 4, the pair of left and right reel arms 32, 32 are configured such that the free end portion at the tip is integrally connected by the pedicle guide bar 30, so that the rigidity is improved and the rotation of the reel is improved. In addition, there is a feature that a stable action can be achieved with less shaking at the time of scratching or the like.

  Next, in the case of the embodiment shown in FIG. 6, the stalk guide bar 30 is provided by being connected to the front / rear adjustment portion 33 of the take-up reel 31 by the interlocking lot 34, and the height position is lowered when the reel 31 is adjusted forward. On the contrary, it is configured to be interlocked so that it can be raised when adjusted backward.

  Therefore, in the case of the embodiment, the stalk guide bar 30 has an advantage that the harvesting operation can be performed while adjusting up and down corresponding to the stalk height of the sunflower as shown by the solid line and the virtual line in FIG. . By such adjustment, the sunflower can be guided to the reaping device 7 from the floret regardless of the length of the pedicle length. The harvesting position from the flower buds is uniform and can be harvested shortly and harvested, and the loss is reduced and the threshing action is stabilized.

  Next, as shown in FIG. 7, the stem guide bar 30 has a narrow guide-shaped portion 30a (front side is narrow and rear side is extended outward) that is inclined outward so that the sunflower stem can be guided to the outside on the left and right sides. ), And the stems that have come into contact with both sides are weeded outside. In this manner, as shown in the drawing, the stem guide bar 30 shown in FIG. 7 has narrow guide shape portions 30a on both outer sides serving as a narrow guide, which guides the uncut stem stem side to shed grains and There is a feature that can prevent damage.

  Next, as shown in FIG. 8 and FIG. 9, the stem and stem guide bar 30 is a virtual front and rear connecting the first cutting blade 7 (reaping device 7) and the second cutting blade 35 (disc cutting blade). A guide recess 36 is formed to be recessed on the directional straight line (A-A line) to receive the pedicle, and only one sunflower stalk is guided to this portion. Therefore, even if the sunflower is planted in multiple rows, only the middle row is guided to the guide recess 36 at the center position, and the upper and lower portions of the sunflower 7 are moved to the first cutting blade 7 as the chassis 1 advances. The second cutting blade 35 cuts away.

  Thus, in the case of the embodiment, the sunflower stems are cut at the position where the upper part (first cutting blade 7) and the lower part (second cutting blade 35) are aligned in the front-rear direction, so that the cut marks are aligned, The release state after cutting is also aligned in the front-rear direction, and the subsequent left and right crawlers 18 are hardly stepped on.

  As shown in FIGS. 10 and 11, the general-purpose combine of the embodiment is provided with a stalk-removing plate 38 inside the left and right crawlers 18 so as to prevent the stalks after cutting from being caught on the crawler 18 side. It is configured to do. Further, as shown in the drawing, the stalk-removing plate 38, 38 is provided over the entire length of the crawler 18 just inside the left and right crawlers 18, and is formed at least higher than the height of the wheel (see FIG. 11). In addition, a guiding portion 38a is formed by bending the front end portion outward at the front side of the front end portion of the crawler 18, and the stems that have become a row after cutting are guided so as to pass below the chassis 1.

  As described above, the left and right crawlers 18, 18 are provided with the stem stalk exclusion plates 38, 38 immediately inside, and further, the guide part 38 a bent outward is formed at the front part, so that the cutting stalk culm is crawled. In order to reduce the damage to the pedicles as much as possible, it is possible to eliminate them from being stepped on or caught in. Thus, when the sunflower stalks are harvested in a state with little damage, there is a feature that the subsequent conversion to bioethanol can be performed without hindrance.

  Next, as shown in FIGS. 12 and 13, the stem culvert guide bar 30 is configured by connecting and connecting both ends to the weed pods 40, 40 on the left and right sides. In this case, as shown in the drawing, the stalk guide bar 30 can guide the stalk at a lower position as compared with the embodiments attached to the reel arms 32 and 32, so that it is effective for a sunflower having a low grain height. It is. And if the stem stem guide bar 30 is attached to the part to be attached to the weed pods 40, 40 via an elastic material and fits a strong resistance force, it is configured to escape upward, so that an unreasonable force is exerted from below during the work. If it works, it can escape upward and damage can be prevented beforehand.

  Thus, when the stem stem guide bar 30 is attached to a low position, such as the weed stems 40, 40 in the low position, a strong force may be exerted because the stem stem guide position is close to the stock. In many cases, it can be protected from breakage if it is configured to be safely retracted upward.

Next, a sunflower harvester according to another embodiment will be described.
First, as shown in FIGS. 14 and 15, the threshing device 50 is mounted on a chassis 52 equipped with a pair of left and right crawlers 51 with a sunflower groom supply port 53 positioned on the front side and harvested on the side.

As shown in FIGS. 14 and 15, the stock holding and conveying device 63 is attached to the front portion of the cutting frame 61 and extends outward and obliquely rearward in a plan view. In this case, the rear portion is inclined and the stem stock is held and conveyed backward.

  Next, as will be understood from the drawings, the upper transport device 65 is configured to transport the upper portion of the pedicle with the lug belt and the guide rod in an engaged state, and starts from above at a distance from the stock holding and transport device 63. The end portion is provided to extend to the upper part of the supply funnel 56.

  And the 1st cutting blade 66 is equipped in the downward position of the starting end part of the said stock holding | grip holding | maintenance conveyance apparatus 63, and the 2nd cutting blade 67 (in this case "cutting | cutting" in the lower position of the terminal part of the said upper conveyance apparatus 65). It is synonymous with “apparatus” and is called “second cutting blade” for the first). In this case, both the first cutting blade 66 and the second cutting blade 67 are composed of a pair of left and right rotating plates, with one being the blade edge and the other being the engagement edge, so that the sunflower pedicle can be cut appropriately. Yes. Reference numeral 69 denotes a dropper.

  The dropper 69 is provided at the rear end portion of the stock holding and conveying device 63, the upper conveying device 65, and the second cutting blade 67, but as in another embodiment shown in FIGS. In addition, if several guide rods 70 are provided, there is an advantage that the sunflower stalks that have fallen after the upper florets have been cut off can be reliably guided into the dropper 69.

  The sunflower harvesting machine configured as described above conveys the sunflower stalks that have been harvested with the first cutting blade 66 as they move forward, pinching the stock with the stock holding and conveying device 63, and the upper part is It is conveyed by the engagement by the conveying lug of the upper conveying device 65. In such a transport process, the stalks of the sunflower are slanted in a state where they are sequentially pulled to the stock side, and when reaching the terminal end of the transport, they are pulled out to the stock side, so that the neck portion of the groom is The second cutting blade 67 is reached and cut.

  Then, the upper flower bud portion is supplied to the handling chamber 58 via the supply funnel 56 and the transfer tool 57 and threshing processed, and the stem bud portion slides on the guide rod 70 (see FIGS. 17 and 18). When they fall and are collected by the dropper 69 and reach a predetermined amount, they fall together on the ground.

  As is well known in the past for rice and wheat combiners, the dropper 69 collects and collects the falling stalks with the guide sledge 70, and when they are dropped together on the ground, the subsequent collection work becomes easy. There is a characteristic that damage to the stem stem is less.

  The sunflower harvester shown in FIGS. 17 and 18 has a configuration in which the stock holding and conveying device 63 is provided in a substantially parallel state with respect to the field scene, and a container 71 is mounted instead of the threshing device 50. The harvesting machine is provided with a second cutting blade 67 on the upper end of the upper conveying device 65 that is inclined in a side view, and an upper feed lug 72 that feeds the floret portion by the conveying lug on the upper side. The configuration is provided. Reference numeral 73 denotes a drop guide plate, which is provided between the upper feed lug 72 and the container 71.

  According to this configuration, since the stock holding and conveying device 63 can take a long distance from the upper conveying device 65, there is a feature that it can sufficiently cope with a variety of sunflower long stem varieties. When the neck portion is cut, the groom portion is sent to the drop guide plate 73 side by the upper feed lug 72 and can be fed into the container 71.

  In this case, the flower part of the sunflower has a holding part (the upper feed lug 72 and the upper transport device 65) just above and below the second cutting blade 67, and the stem is in the locked state, so that it can be cut appropriately. There is also an advantage that can be.
