Hereinafter, the sunflower harvester of the present invention will be specifically described with reference to the drawings.
First, as shown in FIGS. 1 and 2, the combine 13 for harvesting sunflowers has a threshing device 2 on the vehicle body 1 equipped with a pair of left and right crawlers as the traveling device 10 with the cereal supply port 3 in front. It is mounted and connected to the grain supply port 3 with the terminal end of the conveyor 4. As shown in FIG. 5, the threshing apparatus 2 has a handling chamber 14 in which a spiral handling cylinder 16 is pivoted in the front-rear direction and a sorting net 17 is stretched on the lower side. The swing sorting shelf 18 is suspended so as to be swingable, and a pressure wind tang 19, a first transport spiral 20 and a second transport spiral 21 are mounted in that order in order from the upper side of the sorting direction on the lower side. A sorting chamber 15 having a dust exhaust opening is provided below.

  As shown in FIGS. 1 to 4, the pre-cutting processing device 5 connects the collection table 11 to the transfer start end of the transfer conveyor 4, and is mounted on the table 11 in a horizontal direction by a horizontal shaft 22. It is set as the structure which has the taken-in auger 23. Then, as shown in the drawing, the pre-cutting processing device 5 is provided with a first cutting blade 6 on the front side of the collection table 11, and the seed portion on the upper portion of the pedicles cut by the first cutting blade 6 is scraped. The auger 23 is configured to supply to the transfer start end of the transfer conveyor 4 while collecting in the transfer process.

  As shown in FIG. 1, the weed pods 24 are provided on the left and right sides of the front part of the pre-cutting processing device 5, respectively. As shown in FIG. 1, the weed guidance bar 9 guides and guides the plurality of cereal grains in the field to the front side of the first cutting blade 6 to the cutting blade 6 between the left and right weeding baskets 24. In this way, the arrangement is arranged in the horizontal direction.

Reference numeral 25 denotes a take-up reel.
The pre-cutting processing device 5 configured as described above is configured to extend and retract the lifting hydraulic cylinder 26 with the upper horizontal shaft 27 supporting the upper portion of the integrally constructed rear conveyor 4 as a pivot. The height of the first cutting blade 6 is adjusted by moving it up and down.

  Next, as shown in FIGS. 1 to 4, the second cutting blade 7 and the pedicle scraping device 8 are provided behind and below the first cutting blade 6, but are implemented. In the case of the example, the second cutting blade 7 is attached to the transmission support box 29 of the conveyor case 28 so as to be capable of transmission, while the pedicle scraping device 8 can be transmitted to the transmission box 36 provided on the side plate of the collection table 11. It is supported by.

Then, the pedicle scraping device 8 is configured to convey and discharge the pedicle intermediate portion cut by the second cutting blade 7 to the side of the vehicle body 1.
Therefore, first, as shown in FIG. 6, the second cutting blade 7 has the lower ends of the sliding support rods 30 fixed to the left and right sides of the rear portion of the cutting blade, and the cutting blade 7 on one side (the left side in the embodiment). A transmission angle shaft 31 is provided to drive the left side, and the left sliding support rod 30 and the transmission angle shaft 31 are inserted into the transmission support box 29 from the lower side freely up and down, and the other right side sliding support rod 30 is inserted. It is attached to the side plate of the collection table 11 so as to slide freely. As shown in FIG. 6, the cutting blade upper and lower cylinders 32 are connected to the intermediate portion of the sliding support rod 30, and the upper end portion is attached to the conveyor case 28 to expand and contract by hydraulic operation. 7 is adjusted up and down.

  As described above, the second cutting blade 7 can be adjusted up and down by adjusting the cutting height by the above-described lifting hydraulic cylinder 26 together with the first cutting blade 6 integrally with the pre-cutting processing device 5 and the first cutting blade 6. Apart from the vertical adjustment of the cutting blade 6, there is an advantage that the vertical cutting height can be adjusted independently by the expansion and contraction operation of the cutting blade vertical cylinder 32.

In the embodiment shown in FIG. 3, 33 is a grounding rod, and a lot 57 connected to the swing arm 56 is connected to the upper portion so that the second cutting blade 7 can be advanced with respect to the ground.
Then, as shown in FIG. 6, the pedicle scraping device 8 is configured by providing a scraping lug 35 at predetermined intervals on a chain that is rotatably provided inside the transport case 34, and is provided on one side. A transmission support shaft 37 is inserted into and connected to the transmission box 36 from below, and is attached to the lower surface of the collection table 11 with a mounting bracket 55 on the other side.

  As described above, since the second cutting blade 7 and the stalk scraping device 8 are detachably attached to the side plate of the collection table 11 and the conveyor case 28, they can be removed relatively easily. . Therefore, the harvesting machine of the embodiment can be used as a combine for harvesting soybeans by removing both of the above, and it can also be used as a combine for harvesting rice by removing only the stem-pickling device 8.

Next, a schematic mechanism of the transmission mechanism between the second cutting blade 7 and the stalk scraping device 8 will be described with reference to FIG.
First, the rotational power output from the engine 38 is transmitted through the transmission belts 39 and 40 to the upper horizontal shaft 27 that supports the upper portion of the conveyor 4. The transmission support box 29 is inputted from the upper horizontal shaft 27 by the transmission chain 41 and transmits the transmission angular shaft 31 and transmits the take-up reel 25 by the reel transmission chain 42, as can be seen from the drawing. The cutting blade transmission belt 43 transmits the first cutting blade 6 and the transmission belt 44 inputs to the transmission box 36.

The transmission box 36 is configured to transmit the scraper auger 23 and the pedicle scraping device 8 via the transmission support shaft 37 as shown in FIGS. 6 and 7.
As described above, the transmission mechanism of the embodiment uses the transmission mechanism of the existing harvesting pretreatment device of the combine equipped with the conventional full throw-in type threshing device as it is, and the second cutting blade 7 and This is a configuration in which a transmission mechanism that distributes to the pedicle scraping device 8 is added and has a relatively simple transmission configuration.

  Then, as shown in FIG. 8, the pedicle scraping device 8 has a structure in which the pedicle intermediate portion is extended farther than the vehicle body 1 in a plan view, as extended from the right end edge of the collection table 11. It is supposed to be possible. Therefore, the stalk scraping device 8 according to the embodiment is further outside the position where the traveling device 10 passes while transporting the stalk intermediate portion cut by the second cutting blade 7 in the lateral direction when performing the cutting operation. It is configured to be able to be scraped out and discharged to a cut area formed on the right side of the vehicle body 1.

  Next, as shown in FIG. 4, the lowering restricting tool 12 has a front portion at the rear position of the first cutting blade 6 and a rear portion at the upper position of the second cutting blade 7 on both the left and right sides of the collection table 11. Are attached to and fixed to each other, lowered to a position lower than the height of the pedicle scraping device 8 and the second cutting blade 7, and moved forward while sliding in contact with the field ground like a cocoon.

  The lowering restricting tool 12 provided in this way is at the lower limit position of the pre-cutting processing device 5 and restricts the lowering so that it cannot be lowered any further, and the pedicle scraping device 8 scrapes and conveys it to the side. A passage in the middle of the culm (height of the conveyance passage) is secured, and the middle part of the culm can be smoothly transported without being extremely forward tilted. Furthermore, since the second cutting blade 7 and the pedicle scraping device 8 are in a hidden position on the lower side of the collection table 11, the operator cannot see from the cockpit during the operation, and even if it is broken, it is difficult to understand. The lowering restrictor 12 avoids a collision between these and the field scene, prevents breakage, and has a feature that enables safe operation.

Next, the seed discharge device 50 and the glen tank 45 will be described with reference to FIG.
First of all, sunflower seeds are softer and more easily damaged than rice wheat, so they are susceptible to mechanical damage during transportation, and a discharge auger mainly composed of spiral transportation is not suitable. is doing.

  First, as shown in FIG. 9, the Glen tank 45 has a configuration in which seeds after sorting are crushed and supplied from the threshing device 2 by the bucket type threshing device 46. Then, as shown in the drawing, the rotary feeding device 47 is provided with a feeding blade on the front and rear shafts at the lower discharge portion of the Glen tank 45, and when driven by an on / off operation of the discharge clutch, It is set as the structure which pay | throws out the seed of the upper side by a fixed quantity downward.

  The seed discharging device 50 is arranged with the conveying air passage 48 facing the lower side of the rotary feeding device 47, and communicates with the blower 49 connected to the upper conveying side of the conveying air passage 48 for communication. On the lower side, a vertical discharge hose 50a and a horizontal discharge hose 50b are sequentially connected and connected to form a series of conveyance paths. The vertical discharge hose 50a and the horizontal discharge hose 50b are each covered with a cover 52, and a seed discharge port 51 is opened at the tip of the horizontal discharge hose 50b.

  The seed discharge device 50 is configured such that the vertical discharge hose 0a pivots about a virtual central axis, and the upper horizontal discharge hose can move and adjust the seed discharge port 51 up and down. Can be aligned while moving up and down, left and right to the discharge place (for example, the tank of a truck waiting on a farm road).

  In the seed discharge device 50 configured as described above, when the glen tank 45 reaches a full tank and moves to the discharge operation, first, after the seed discharge port 51 is aligned, the operator enters the discharge clutch and operates it. Then, the blower 49 is driven. Then, the conveying air is blown up by the blower 49 and forcibly supplied to the start end side of the conveying air passage 48, blown through the discharge hoses 50a and 50b, and blown out of the apparatus from the discharge port 51. Then, when power is transmitted to the rotary feeding device 47 and feeding rotation is started, sunflower seeds filled in the Glen tank 45 are fed to the conveying air passage 48 by a fixed amount from the upper side to the lower side. The conveyance is started in response to the wind pressure of the conveyance air blown toward.

In this way, the sunflower seeds are discharged from the glen tank 45 to the tank of the truck outside the machine and harvested with less mechanical damage by air conveyance.
As described above, the embodiment of the present invention transports and supplies the upper part of the sunflower stalks harvested by the first cutting blade 6 and the seed part attached thereto to the threshing device 2 for threshing selection. When cutting, the upper part of the pedicle is cut short, so that it can be well selected with little contamination. And even if the lower pedicle intermediate part is cut off with a relatively long length, it is scraped and conveyed laterally by the pedicle scraping device 8 and is regularly emitted to the side of the vehicle body 1 and scattered in the field scene. There is no. Sunflower has recently been developed and cultivated with low height, and can be smoothly scraped and conveyed in the horizontal direction.

  And, since the embodiment of the present invention guides and guides the upper portion of the stalks planted in the field and standing in an unstable state to the first cutting blade 6 while supporting from the left and right sides by the weed guide rods 9, Mowing in a state close to a stable upright. And since this invention conveys and discharge | releases the intermediate part of the stem stalk which the 2nd cutting blade 7 cut off from the path | route which the traveling apparatus 10 passes by the stalk scraping device 8, it is stepped on by the crawler 10. This makes it easier to collect after the fact.

  In the present invention, the middle portion of the stalk pruned by the second cutting blade 7 is discharged to the already-cut area by the stalk scraping device 8, so that it can be stepped on by the traveling device 10 as already described. Needless to say, in the case of turning, when the second cutting is carried out, the previous cutting release stem does not interfere with running and cutting, and the operation by turning can be efficiently continued.

  In the present invention, since the lowest position of the pre-cutting processing device 5 is determined by the lowering restricting tool 12, the height of the scraping passage in the middle portion of the culm formed on the lower side of the collection table 11 is always set. Can be held. Therefore, according to the present invention, in the process in which the pedicle intermediate part is conveyed to the side by the pedicle scraping device 8, the posture is extremely tilted forward and is not in an unstable state, but is scraped smoothly.

  The lowering restrictor 12 of the present invention protects the second cutting blade 7 and the pedicle scraping device 8 that are on the back side (lower side) of the collection table 11 and cannot be seen by the operator from the steering position. They also work to prevent them from colliding with the ground and breaking during running.
