Description

  TECHNICAL FIELD The present invention relates to a green soybean extractor used for harvesting green soybeans, and more particularly to a herbicidal device that makes it easy to understand the position of a green soybean plate to be harvested.

  Conventionally, when harvesting beans such as green soybeans and tea beans cultivated in the field, a machine is applied to the stem leaves and the straw is removed (dehulling), or the upper stem leaves are cut off from the ground by the machine. Then, the method of how to do the removal was taken afterwards. However, in any case, since the remaining stem leaves and stem roots cannot be left as they are, it is necessary to remove them. In particular, in the former case, the stem and leaf part must be pulled out together with the stem root, which is a very laborious work. On the other hand, in the latter case, when the soil is cultivated, the roots are sown and reversed with the cultivated soil.

It is supposed to prevent tangling. Note that the fact that the above-described two weed ridges 19g and 19h can be rotated about a substantially front-rear axis contributes to reducing the overall width by storing them when traveling on the road or transporting the aircraft.

  The scraping device 12 is provided behind the weeding device 11 in the same shape as the machine base 2, and is provided with a protruding belt 21 stretched between a pair of upper and lower pulleys (not shown) on the left and right. Both of the opposing surfaces are rotated backward in the front, low, and high inclined planes, and the stem-leaved portion 7a to be pulled out is scraped up by the belt 21 with protrusions and guided to the subsequent holding and conveying device 13. Accordingly, the center of the opposed belt 21 with protrusions is made to coincide with the center of the holding and conveying device 13. A cover 22 is covered on the upper surface of the belt with protrusions 21 to prevent the stem leaf portion 7a from being bitten. The cover 22 is positioned so as not to block the line of sight e when the operator holding the steering handle 5 looks at the tip of the weed board 18a.

  The holding and conveying device 13 is provided in the same shape as the machine base 2 behind the scraping device 12, and a pair of left and right belt conveying portions 13a having an elastic belt 23 stretched between a pair of upper and lower pulleys (not shown). 13b, and the left and right elastic belts 23 of the transport portions 13a and 13b are pressed against each other and are both rotated rearwardly in a front, rear, rear, and high inclined plane. It is positioned so as to sandwich only a part or a part of the range of about 10 cm or less from the ground at the lower end of the trunk of the green soybean 7 at a height that does not sandwich the multi-film 45 covered with the ridge 6 so as to be in close contact with the ground. And the front-rear position is substantially matched with the rotation center of the gauge wheel 10, the lower end portion of the stem leaf portion 7a scraped by the scraping device 12 is sandwiched by the elastic belt 23 and pulled out from the ground, and Rear upper It is intended to convey. Here, the holding and conveying device 13 holding the vicinity of the lower end portion of the stem and leaf portion 7a contributes to preventing damage to the wrinkles and the like growing under the stem and leaf portion 7a. In addition, the nipping and conveying start end f substantially coincides with the rotation center of the gauge wheel 10 because the gauge wheel 10 has the same height as that before the nipping and conveying start end f is inclined even if the machine body is inclined with respect to the saddle 6. It is possible to hold it. The pressing force of the elastic belt 23 is set so as to exert a force sufficient to pull out the stem 7b in the ground with the stem 7a sandwiched. Since 7c must not be crushed, a soft elastic body such as a sponge is used on the surface. A cover 24 is provided over the elastic belt 23 to prevent the stem leaves 7a from being bitten.

  The vibration device 14 is provided in the vicinity of the starting end portion of the holding and conveying device 13, and mainly includes a vibrating blade 25 having a reverse L-shape when viewed from the front with a vertical portion 25a and a horizontal portion 25b. The lower soil is loosened to make it easier to pull out the trunk leaf portion 7a. In this case, the soil below the pedicle 7b is loosened by the vibration device 14 before the stem and leaf portion 7a is subjected to the pulling action by the holding and conveying device 13. The vertical portion 25a is pivotally supported by the machine body 2 and the like with a pin 26, and a crank rod 27 is connected to the upper portion of the vertical portion 25a so as to vibrate back and forth. The horizontal portion 25b of the oscillating blade 25 is inserted from the hem of the end of the heel 6 and reaches the lower portion of the stem 7b of the extracted stem leaf portion 7a, but rises upward around the lower portion of the stem 7b. The ease of extraction is ensured by approaching or directly touching the root 7b. Accordingly, the start end of the horizontal portion 25b, that is, the end of the vertical portion 25a is bent sideways, and even when the upper surface of the collar is covered with the multifilm 45, the vibrating blade 25 (the horizontal portion 25b ) Can rush into the ridge 6 to support multi-cultivation. The vibration device 14 is installed when the stalk 7b extends deeply into the ground and has a strong pulling resistance, and is removed when the pulling resistance is small due to premature growth or the like.

  The earth dropping device 15 is provided in the lower part of the sandwiching and conveying device 13, and has a toothed drum 28 that is rotated in a state where the central axis is included in the vertical plane, and a rubber plate that is provided to face the drum 28. 29, which acts on the pedicle root 7b being transported by the sandwiching and transporting device 13 and drops the soil attached thereto. FIG. 5 is a cross-sectional view taken along the line A-B in FIG. 1 showing the main part, and FIG. 6 is a cross-sectional view taken along the line B-B. There is a drum 31 that protrudes forward from a housing 30 that houses the transmission structure, and teeth 32 are implanted on the outer periphery of the drum 31. And the rubber plate 29 is provided in the location within the action | operation range of the tooth-handling 32, and even if the tooth-handling 32 strikes the pedicle 7b, this will be blocked by the rubber plate 29 and will not escape.

  In this case, the central axis of the drum 31 is set below the elastic belt 23 of the holding and conveying device 13 and in parallel with the transfer direction in a plan view, but in an intersecting state where the front opens or the rear opens in a side view. Is set to This is because it gradually acts on all the stems 7b and surely drops the soil. The mounting position and angle of the housing 30 with respect to the fixing member such as the machine base 2 can be changed, and thereby the correlation with the elastic belt 23 can be adjusted. In addition, a hitting bar 32a is handed over in the longitudinal direction to the tooth handling 32, and even when soil is attached as a lump A to the pedicle root 7b, it is struck and cracked. . Even if the stalk 7b is to be wound around the drum 28 having the tooth handling, since the hitting bar 32a is located at a position away from the drum 31 in the radial direction, it is difficult to wind, and even if it is wound, it can be easily removed. .

  The lateral guiding device 16 is provided at the conveyance end of the belt conveying unit 13b on the left side of the sandwiching and conveying device 13, and guides the green soybeans conveyed by the sandwiching and conveying device 13 to the collecting device 17, and FIG. FIG. 8 is also a cross-sectional side view showing the main part of the device 16, and FIG. 8 is a view taken in the direction of the arrow C in FIG. 7. 34a overlaps with the feed claws 34 projecting from the outer periphery of the drum 33, and the distance between the upper and lower feed claws 33, 33 at the trunk portion is narrow, and the gap between the upper and lower feed claws 33, 33 at the trunk tip side. In this state, the leaf drum 33 and the feed claw 34 are driven by the upper pulley 23a. FIG. 9 is a cross-sectional view taken along the line DD in FIG. 7. The feed claw 34 has a ring shape as a whole, and the inner hole 34 b is externally fitted and fixed to the drum 33. The relative displacement is regulated by fitting a plurality of protrusions 34 c formed on the inner peripheral surface of the inner hole 34 b into the through holes formed in the drum 33.

  A guide plate 35 is provided at substantially the same position as the transfer surface of the left elastic belt 23 so as to rise up to the height of the uppermost feed claw 34 and go around the outside of the drum 33 and extend leftward. Provided with a stem-leaf guide rod 36 that goes out of the same body part as the cover 24 of the right elastic belt 23 and circulates around the outer periphery of the guide plate 35 at a predetermined interval so that the guide action of the rod 19c can be continuously taken over. It is. The stem-leaf guide rod 36 has a curved portion at the rear thereof forming a part of the lateral guiding device 16, and a front-rear facing portion pushes the stem-leaf portion 7 a transported by the sandwiching and transporting device 13 to the left until reaching the lateral guiding device 16. It plays the action.

  The guide plate 35 also serves as a cover 35a covering the top of the uppermost feed claw 34. When the stem leaf portion 7a wraps around, the guide plate 35 hangs down on the stem leaf portion 7c, or the stem leaf portion is removed. 7a is prevented from being wound around the feed claw 34. In this case, there is a hole 37 at the location of the guide plate 35 where the feed claw 34 interferes, and the claw 34a rotates out of the guide plate 35. As a result, the stem and leaf portion 7a conveyed by the holding and conveying device 13 is pushed into the guide path 38 formed by the guide plate 35 and the stem and leaf guide rod 36, and is forced to the left by the claw 34a of the feed claw 34. Sneak into.

  The collecting device 17 is mainly composed of a collecting plate 39 provided on the left side of the airframe 2 following the guiding path 38, and stores a certain amount of the stem and leaf portion 7a discharged from the guiding path 38 on this. is there. The collecting plate 39 is provided so as to be able to rotate downward around a support shaft 40 provided on the machine body 2 side, and when the stem and leaf portion 7a reaches a certain amount, it automatically or manually rotates and accumulates on the collecting plate 39. The stem leaf portion 7a is released. This is to make it easier to collect later. Moreover, it is also for turning down at the time of driving | running | working on a road and conveyance, and to suppress a full width (it may rotate up at the time of storage).

  Each of the above working units 3 is driven by the transmission unit 4, and the drive system is divided into a traveling system and a working system. Since the configuration is the same as this type of work machine, the schematic configuration will be described below with illustration omitted. First, regarding the traveling system, the power transmitted to the transmission unit 4 is transmitted from the transmission case 20 to the axle 41 by the drive shaft accommodated in the transmission cylinder 9 to drive the traveling wheel 1.

  On the other hand, for the work system, the power transmitted to the transmission unit 4 is transmitted to the upper pulley shaft of the elastic belt 23 of the holding and conveying device 13 to rotate the elastic belt 23. Further, the left side of the upper pulley shaft protrudes upward, and the drum 33 and the feed claw 34 are fitted to this to drive it. Furthermore, the power is transmitted from an appropriate roller that stretches the elastic belt 23 to the upper pulley shaft of the protruding belt 21 of the scraping device 12, thereby rotating the protruding belt 21. Further, the power transmitted to the transmission unit 4 takes an appropriate drive path to drive the crank rod 27 that vibrates the vibration blade 25 of the vibration device 14 and also drives the drum 28 with projections of the earth dropping device 15.

  In addition to the above facilities, a gate 42 is provided at the front of the body 2 near the rear of the weeding device 11. This gate 42 connects the left and right so that the belt 21 with the left and right protrusions 21 constituting the scraping device 12 does not cause deformation or the like when the stem leaves 7a are taken into the opposite surface, or adds weight to the front part. The body 2 is balanced, and the center thereof is provided to coincide with the transport surface of the stem leaf portion 7a (the mating surface of the elastic belt 23 of the sandwiching transport device 13). Submerged 42 and conveyed backward. Therefore, the gate 42 is set to a height that does not hinder the conveyance of the stem and leaf portion 7a. As described above, the gauge wheel 10 is provided on the left side of the machine body 2, but it goes without saying that the gauge wheel 10 moves up and down together with the fork member 10 a with the handle 44 on the storage cylinder 43 fixed to the machine body 2. This sets the height of the working unit 3. On the fork member 10a, a scraper 10c that scrapes off the earth and sand adhering to the gauge wheel 10 is fixed in a slanting manner so that the gauge wheel 10 travels in a trough groove 6b on which earth and sand easily adhere. Even if earth and sand adhere to the gauge wheel 10, the scraper 10c reliably scrapes off the earth and sand, and does not cause disturbance in the height of the working unit 3 due to the adhesion of earth and sand. At this time, the fact that the scraper 10c is in a front-lowering shape contributes to preventing the trunk leaf portion 7a from being caught in addition to promoting the falling of the scraped earth and sand.

  About the height of the working part 3, it adjusts so that the front-end | tip of the weeding board 18 of the weeding device 11 may keep a close distance on the top 6a. However, when the multi-film 45 is put on the crown 6a, the interval is set so that the tip of the weed plate 18 does not break the multi-film 45. And the film pressing bar 46 which presses the multi-film 45 is provided in the both sides which pinch the harvest strip of the green soybeans 7 in the back of the vibration apparatus 14 a little. At this time, the front end portion of the film pressing bar 46 is inclined forward and the front and rear positions thereof are positioned in the vicinity of the nipping / conveying start end f of the nipping / conveying device 13 behind the scratching start position f0 of the scraping device 12. . Therefore, when the stem 7b is pulled out from the planting hole of the multi-film 45, the situation where the multi-film 45 is lifted and sandwiched between the elastic belts 23 or the stems and the like are trapped is prevented. The multi-film thus prevented from being damaged is reused as necessary, and in the re-use, necessary planting is carried out in the hole portions formed in the multi-film remaining on the trace of the stem 7b pulled out. Is called.

  Furthermore, the illumination means 47 which illuminates each working part 3 is provided. In addition to the illumination lamp 47a for irradiating the tip of the one side weed plate 18a, the illumination means 47 can change the illumination direction and can illuminate the collecting device 17 and other places. And. At this time, the former illuminating lamp 47 a is fixed near the upper end of the upright member 2 a, and a plurality of the latter illuminating lamps 47 b are mounted above the front part of the steering handle 5. These lighting lamps 47a and 47b are used in different ways depending on whether they are planted in a single row or a single row, and in the case of single row and single row planting, the tip of the right weed plate 18a is not seen. However, the former illuminating lamp 47a does not have to be turned on. In this case, the latter illuminating lamp 47b irradiates the front part of the sandwiching and conveying apparatus 13 and the collecting apparatus 17, while In the case of double row planting, the tip of the right weed plate 18a and the collection device 17 are irradiated.

  In the above-described embodiment, the weed culm 19c and the stem and leaf guide rod 36 form the stem and leaf guide means, and the stem and leaf portion that has passed between the left and right weed plates 18a and 18b during the harvesting run. 7a is first pushed to the left side while moving backward by the weed ridge 19c, and further pushed to the left side after being sandwiched by the sandwiching and transporting device 13, and thereafter transported by the sandwiching and transporting device 13. In the process of approaching the rear end of the weed culm 19c, the next is transported while being pushed leftward by the trunk leaf guide rod 36 and finally guided laterally outward by the lateral guiding device 16 and onto the collecting device 17 Be dropped. While such a harvesting process is being performed, the operator holds the steering handle 5 and observes the tip of the right weed plate 18a while keeping it away from the harvesting row to the right and along the row. At this time, since the trunk leaf portion 7a being harvested is pushed away from the operator's line of sight e by the stem and leaf guide means 19c, 36, the pilot's line of sight e is the stem leaf portion 7a. Therefore, the operator can always accurately and accurately see the tip of the weed plate 18a during the harvesting run even in the harvesting of the soybeans 7 etc. where the stems 7a are prosperous. The part 3 can be made to act on the row of green soybeans in an optimum state.

  In carrying out the above harvesting, the small weed board 18a means that when the operator holding the steering handle 5 looks at the tip of the weed board 18a, the weed board 18a itself blocks the operator's line of sight e. It is effective in preventing the situation, and the pair of left and right lower weed ridges 19a and 19b and the pair of left and right upper weed ridges 19c and 19d have a reduced weeding ability due to the small weed board 18a. These weed ridges 19a to 19d provide a gap between them, making it easy for the operator to pass the line of sight e when looking at the tip of the weed plate 18a, and to perform an accurate harvesting process. It contributes to doing.

  On the one hand, the gap between the upper weed ridges 19c and 19d and the lower weed ridges 19a and 19b may cause the stem leaves 7a to pass backward. In this case, the stem leaves are excluded. The guide plate 18c smoothly guides the passing trunk leaf portion 7a obliquely rearward, and therefore, the situation where the trunk leaf portion 7a is entangled with the lower end portion of the upright member 2a is prevented.

  By the way, edamame etc. are harvested from early morning to avoid fissures and a decrease in freshness. In such a case, the illumination lamp 47a irradiates the tip of the right weed plate 18a intensively. Therefore, the driver can perform accurate driving even in the case of planting two or one row. Further, since the collecting device 17 can be intensively illuminated by another illumination lamp 47b, the operator can visually check the state of the harvested green soybeans on the collecting device 17 at any desired time. It can be processed. If necessary, it is possible to illuminate an arbitrary place by changing the irradiation angle of the illumination lamps 47a and 47b.

  The weeding board 18e in front of the gauge wheel 10 scoops up the trunk leaf portion 7a prospering in the ridge groove 6b and feeds it to the upper edge of the supporting plate member 10b during the harvesting traveling of the aircraft. The support plate member 10b comes into contact with the stem leaf portion 7a in front of the support plate member 10b and effectively assists the stem leaf portion 7a to move to the left outer side by the weeding action of the weed pod 19i. As the weed ridge 19i heads backward, the stem leaves 7a on the front outer side, the stem leaves 18b, the weed boards 18e, and the stem leaves 7a sent obliquely laterally rearward from the support plate member 10b are moved backward. As a result, the trunk leaves 7a are prevented from being entangled with the gauge wheel 10 or the left traveling wheel 1 gradually.

  The weed plate 18d is used to divide the vegetation green soybeans left and right in front of the right traveling wheel 1 during the harvesting run of the aircraft and send them to the outside of the left and right weed pods 19g, 19h. Prevents the right traveling wheel 1 and the rotation center shaft holding portion 4a from being entangled. At this time, the weed pod 19g swings about the axis in the front-rear direction, so that the height against which it presses against the stem and leaf portion 7a differs, and adapts to various growth heights of green soybeans. In addition, by changing the posture of the weed board 18d around the left and right axis a together with the weed pods 19g and 19h, the weed board 18d and the weed vines 19g and 19h can change the range of action on the vegetation green soybeans, It will be adapted to various growth heights.
