The fact that the two weeding rods 19g and 19h are rotatable substantially in the front-rear direction also contributes to the storage of the two weeding rods 19a and 19b during traveling on the road and the transport of the body, thereby suppressing the overall width.

The scraping device 12 is provided behind the weeding device 11 in the same manner as the machine base 2, and has a belt 21 with a projection stretched between a pair of upper and lower pulleys (not shown). The opposing surfaces are both rotated rearward in the front-low-back high-inclination plane, and the protruding belt 21 scrapes up the stem-and-leaf portion 7a to be extracted and guides the stem-leaf portion 7a to the subsequent nipping and conveying device 13. It is. Therefore, the center of the facing belt 21 with projections is made to coincide with the center of the nipping and conveying device 13. A cover 22 is provided on the upper surface of the belt 21 with protrusions.
Are covered to prevent the stem leaf 7a from biting or the like. The cover 22 is positioned so as not to block the line of sight e when the operator holding the steering wheel 5 looks at the tip of the weeding board 18a.

The nipping and conveying device 13 is provided behind the scraping device 12 in the same manner as the machine base 2, and has a pair of left and right belts having an elastic belt 23 stretched between a pair of upper and lower pulleys (not shown). The transport units 13a and 13b are formed, and the opposing surfaces of the left and right elastic belts 23 of the transport units 13a and 13b are pressed against each other, and both of them are rotated rearward in a front-low-back high-inclination plane.

Here, the nipping and conveying device 13 nipping the vicinity of the lower end of the stem and lobe portion 7a contributes not to damage pods and the like growing below the stem and lobe portion 7a. Also, the fact that the nipping and conveying start end f is substantially aligned with the center of rotation of the gauge wheel 10 in the front-rear position means that the gauge wheel 10 has the nipping and conveying starting end f at the same height as before the inclination even when the body is inclined with respect to the ridge 6. It is possible to hold the information in the storage area. The pressing force of the elastic belt 23 is set so as to exert a force enough to pull out the underground root 7b while the stem and leaf 7a is 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 above the elastic belt 23 to prevent the stem leaf 7a from biting.

The vibrating device 14 is provided near the starting end of the holding and conveying device 13, and is mainly composed of a vibrating blade 25 having a vertical portion 25a and a horizontal portion 25b having an inverted L shape in a front view.
The soil under the roots 7b is loosened by the horizontal portions 25b,
This makes it easier to pull out a. In this case, stem and leaf 7
Before a is subjected to the pulling-out action by the holding and conveying device 13, the soil below the shoot root 7 b is loosened by the vibration device 14. The vertical portion 25a is rotatably supported by the body 2 or the like by a pin 26, and has a crank rod 2

Is inserted from the skirt of the end of the ridge 6 and extends to the lower part of the root 7b of the drawn stem / leaf portion 7a.
In the vicinity of the lower part of the root 7b, the root is raised upward to be brought close to the root 7b or to be in direct contact with the root 7b, thereby facilitating the removal. Therefore, the start end of the horizontal portion 25b, that is, the end of the vertical portion 25a is bent horizontally, and even if the upper surface of the ridge is covered with the multi-film 45, the vibration blade 25 (the horizontal portion 25b ) Can enter the ridge 6 to support multi-cultivation. The vibrating device 14 is provided when the stem root 7b extends deeply into the ground and has a high pullout resistance, and is removed when the pullout resistance is small due to early birth or the like.

The earth removal device 15 is provided below the middle of the holding and conveying device 13, and is provided with a toothed drum 28 which is rotated with its central axis included in a vertical plane, and is provided opposite thereto. It acts on the roots 7b being conveyed by the nipping and conveying device 13 to remove soil attached thereto. 5 is a sectional view taken along the arrow A of FIG. 1 and FIG. 6 is a cross-sectional view taken along the line BB of FIG. 1. The toothed drum 28 is in the form of a drum of a threshing machine. From the housing 30 containing the transmission structure to the drum 3
Numeral 1 protrudes forward in a freely rotatable manner, and has teeth 32 implanted on the outer periphery of the drum 31. And the tooth handling 32
A rubber plate 29 is provided at a position within the range of operation of the present invention, so that even if the teeth 32 hit the pedicle 7b, the rubber plate 29 blocks the stalk 7b so that it does not escape.

In this case, the center axis of the drum 31 is set below the elastic belt 23 of the nipping and conveying device 13 and is parallel to the transfer direction in a plan view. The intersection is set to open. Root 7
The reason is that the soil is gradually removed from b, and acts on everything to reliably remove the soil. The mounting position and the angle of the housing 30 with respect to the fixing member such as the machine base 2 can be changed, so that the correlation with the elastic belt 23 can be adjusted. In addition, a tapping rod 32a is passed over the tooth handling 32 in the longitudinal direction, and the pedicle 7b
Even if the soil adheres as a lump A, it is broken. In addition, broken stem root 7b
Tries to wind the drum around the toothed drum 28,
Since 2a is located at a position distant from the drum 31 in the radial direction, it is difficult to wind and even if wound, it is easy to remove.

The lateral guiding device 16 is provided at the transport end of the belt transport section 13b on the left side of the nipping transport device 13,
7 is for guiding green soybeans conveyed by the holding and conveying device 13 to the collecting device 17, FIG. 7 is a cross-sectional side view showing a main part of the guiding device 16, and FIG. Above the end of one (left) elastic belt 23 (cover 24)
The drum 33 and the feed claws 34a whose claws 34a protrude to the outer periphery of the drum 33 are superposed in a stepped manner, and the interval between the upper and lower feed claws 33, 33 of the stem base is narrow, so that the trunk tip side The leaf drum 33 and the feed claw 34 are driven by the upper pulley 23a in a state where the distance between the upper and lower feed claws 33, 33 is widened. FIG. 9 is a sectional view taken along the line D-D in FIG.
4b is externally fitted to the drum 33 and fixed. The relative displacement between the feed claw 34 and the drum 33 is achieved by forming a plurality of projections 34c formed on the inner peripheral surface of the inner hole 34b into through holes formed in the drum 33. It is regulated by fitting.

At substantially the same position as the transfer surface of the left elastic belt 23, there is provided a guide plate 35 which rises up to the height of the uppermost feed claw 34, extends around the outside of the drum 33, and extends to the left. A stem leaf guide rod 36 which exits from a part of the same shape as the cover 24 of the right elastic belt 23 and rotates around the outer periphery of the guide plate 35 at a predetermined interval so that the guiding action of the weeding rod 19c can be continuously taken over. It is provided. 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-rearward portion pushes the stem / leaf portion 7 a conveyed by the sandwiching conveying device 13 to the left until reaching the lateral guiding device 16. It has the function of sending.

The guide plate 35 is provided with the uppermost feed claw 3.
4 is also used as a cover 35a that covers the upper part of
When a wraps around, the pod 7c hangs down on the pod 7c to prevent the pod 7c from falling off and the stem lobe 7a from wrapping around the feed claw 34. In this case, a hole 37 is provided at a position of the guide plate 35 where the feed claw 34 interferes, and the claw 34a comes out of the guide plate 35 and rotates. Thus, the stem-and-leaf portion 7a conveyed by the nipping conveyance device 13 is guided by the guide plate 35.
And the guide leaf 36 formed by the stem and the stem leaf guide rod 36, and is forcibly turned to the left by the claw 34 a of the feed claw 34.

The collecting device 17 is mainly composed of a collecting plate 39 provided on the left side of the body 2 following the guiding route 38, and stores a certain amount of the stem leaf 7a discharged from the guiding route 38 thereon. It is something to put. The collecting plate 39 is provided so as to be rotatable downward around a support shaft 40 provided on the body 2 side. When the stem / leaf portion 7a reaches a certain amount, the collecting plate 39 is automatically or manually rotated and accumulates thereon. The stem leaves 7a are released. This is because the collective operation can be easily performed later. It is also for lowering the whole width by turning downward when traveling or transporting on the road (it may turn upward when storing).

Each of the working units 3 described above is driven by a transmission unit 4. The driving system is divided into a traveling system and a working system. Since the configuration is the same as that of this type of working machine, a schematic configuration will be described below without illustration.
First, with respect to 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 wheels 1.

On the other hand, with respect to the working 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.
The left side of the upper pulley shaft protrudes upward,
The drum 33 and the feed claw 34 are fitted on this, and this is also driven. Further, the power is transmitted from an appropriate roller that stretches the elastic belt 23 to the upper pulley shaft of the belt 21 with the projection of the scraping device 12, whereby the belt 2 with the projection is moved.
1 is rotated. Further, the motive power transmitted to the transmission unit 4 drives a crank rod 27 that vibrates the vibrating blade 25 of the vibrating device 14 through an appropriate driving path, and
The fifth drum 28 with projection is also driven.

In addition to the above facilities, a gate 42 is provided at the front of the body 2 around the rear of the weeding device 11. The gate 42 connects the left and right so that the left and right protruding belts 21 constituting the scraping device 12 do not cause deformation or the like when the stem leaf portion 7a is taken into the facing surface, or adds weight to the front portion. The center of the trunk 2a is provided so as to coincide with the transfer surface of the stem-and-leaf portion 7a (the mating surface of the elastic belt 23 of the nipping and conveying device 13).
a is transported backward through the gate 42. Therefore, the gate 42 is set at a height that does not hinder the conveyance of the stem / leaf portion 7a. As described above, the gauge wheel 10 is provided on the left side of the body 2, but, naturally, the gauge wheel 10 is attached to the storage tube 43 fixed to the body 2 by the handle 44.
, So as to move up and down together with the fork member 10a, thereby setting the height of the working unit 3. On the fork member 10a, a scraper 10c for scraping off the earth and sand attached to the gauge wheel 10 is fixed in a downwardly inclined shape, and the gauge wheel 10 travels in a ridge groove 6b to which the earth and sand easily adhere. Even if earth and sand adhere to the gauge wheel 10, the scraper 10c surely scrapes the earth and sand, so that the height of the working section 3 is not disturbed by the adhesion of earth and sand. At this time, the fact that the scraper 10c is made to be in a forward falling shape not only promotes the falling of the scraped earth and sand, but also causes the stem and leaf portion 7 to fall.
This contributes to preventing a from being caught.

Regarding the height of the working section 3, the weeding device 11
Of the weeding plate 18 is adjusted so as to keep a close distance on the ridge top 6a. However, when the ridge 6a is covered with the multi-film 45, the interval is set so that the tip of the weeding plate 18 does not break the multi-film 45. Further, film holding rods 46 for holding the multi-film 45 are provided slightly behind the vibrating device 14 and on both sides of the crop of the green soybeans 7. At this time, the front end of the film holding bar 46 is inclined forward and its front / rear position is located near the nipping / conveying start end f of the nipping / conveying device 13 behind the raking start position f0 of the raking device 12. . Therefore, when pulling out the stem root 7b from the planting hole of the multi-film 45, it is possible to prevent the multi-film 45 from being lifted up and caught by the elastic belt 23, or a pod or the like of the stem and leaf portion from being caught. The multi-film which has been prevented from being damaged in this way is reused as necessary. In the case of re-use, necessary planting is carried out in the holes formed in the multi-film remaining in the trace where the shoot root 7b was pulled out. Will be

Further, illumination means 47 for illuminating each working section 3 is provided. The lighting means 47 is provided on one side of the weeding plate 18.
In addition to an illuminating lamp 47a for irradiating the front end of the light emitting device a, an illuminating lamp 47b capable of changing the irradiating direction and irradiating the collection device 17 and other parts is provided. At this time, the former illumination lamp 47a is fixed near the upper end of the upright member 2a, and a plurality of the latter illumination lamps 47b are mounted above the front part of the steering handle 5. These illumination lamps 47a, 47
For b, the method of use is appropriately changed between the case of single-row single-row planting and the single-row double-row planting. In the case of single-row single-row planting, it is not necessary to look at the tip of the weeding plate 18a on the right side. The lamp 47a does not need to be turned on. In this case, the latter part of the holding and conveying device 13 and the collection device 1 are connected by the latter illumination lamp 47b.
In the case of two-row single-row planting, on the other hand, the tip of the weeding plate 18a on the right side and the collecting device 17 are irradiated.
Is irradiated.

In the above embodiment, the weeding rod 19
c and the stem leaf guide rod 36 constitute stem leaf guide means. During harvesting, the stem leaf part 7a that has passed between the left and right weeding plates 18a, 18b is first moved backward by the weeding rod 19c. It is gradually pushed to the left while moving toward it, and further pushed to the left even after being pinched by the pinching / conveying device 13,
Thereafter, when the vehicle approaches the rear end of the weeding rod 19c in the process of being conveyed by the nipping and conveying device 13, it is conveyed while being pushed to the left by the stem / leaf guide rod 36, and finally the lateral guidance device 1
It is guided laterally outward by 6 and dropped on the collecting device 17. During such a harvesting process, the operator holds the steering handle 5 and, while visually observing the tip of the weeding plate 18a on the right side, appropriately separates the harvesting row to the right and follows the row. At this time, the stem and leaf portion 7a during harvesting is pushed away from the line of sight e of the pilot by the stem and leaf guide means 19c and 36, so that the line of sight e of the pilot is changed to these stem and leaf portions 7a. Therefore, even when harvesting green soybeans 7 or the like with thick stem and leaf portions 7a, the pilot can always accurately see the tip of the weeding plate 18a during harvesting. The part 3 can be made to act optimally on the row of green soybeans.

When the harvesting is performed, the small size of the weeding board 18a means that when the operator holding the steering wheel 5 looks at the tip of the weeding board 18a, the weeding board 18a itself is seen by the driver. e, which is effective in preventing a situation in which the weeds are blocked, and a pair of left and right lower weeding rods 19a, 19b and a pair of left and right upper weeding rods 19c, 19d are provided with a small weeding plate 18a to provide weeding ability. In addition, the weeding rods 19a to 19d provide a gap between them to facilitate the passage of the pilot's line of sight e when seeing the tip of the weeding plate 18a, and thus to be accurate. It contributes to performing a suitable harvesting process.

The gap between the upper weeding rods 19c and 19d and the lower weeding rods 19a and 19b may cause a passage behind the trunk 7a on the one hand. In this case, The stem lobe excluding guide plate 18c smoothly guides the stem lobe 7a that has passed through to the obliquely rearward direction, so that the stem lobe 7a is not entangled with the lower end of the upright-shaped member 2a.

By the way, green soybeans are harvested early in the morning before dawn in order to avoid pod breakage and freshness deterioration.
In such a case, since the illumination lamp 47a irradiates the tip of the right weeding plate 18a intensively, the driver can perform an accurate driving even in the case of two-row single-row planting. In addition, since the collection device 17 can be intensively irradiated by another illumination lamp 47b,
The operator can visually confirm the accumulated state of the harvested green soybeans on the collection device 17 at any time when necessary, and can perform the processing of the harvested green soybeans appropriately. If necessary, the lighting 4
It is also possible to change the irradiation angles of 7a and 47b to illuminate an arbitrary position.

The support plate member 10b abuts against a 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 outside by the weeding action of the weeding rod 19i.
The weeding rod 19i moves the stem leaf portion 7a on the front outer side thereof, the stem leaf portion 7a sent from the weeding plate 18b, the weeding plate 18e, and the support plate member 10b obliquely to the rear as it goes rearward. The stem leaves 7a are gradually pushed laterally outward to prevent these stem lobes 7a from becoming entangled with the gauge wheel 10 and the left running wheel 1.

The weeding plate 18d is used to push vegetation green soybeans to the left and right in front of the right running wheel 1 during the harvesting operation of the body and to send it to the outside of the left and right weeding rods 19g and 19h. Prevents vegetation green soybeans from getting entangled with the right traveling wheel 1 and the rotation center shaft holding portion 4a. At this time, weeding rod 1
9g has a different height at which it is pressed against the stem and leaf portion 7a by swinging about a longitudinal axis, and is adapted to various growth heights of green soybeans. Weeding board 18
By changing the posture of d with the weeding rods 19g and 19h around the left-right axis a, the range of action of the weeding board 18d and the weeding rods 19g and 19h on vegetated green soybeans is also changed, and various growths It will adapt to the height.

As described above, the present invention has the following advantages. That is, as in claim 1, in a soybean extracting and harvesting machine equipped with a scraping device for scraping a row of vegetation green soybeans on a ridge backward, and a sandwiching and conveying device for sandwiching and conveying the scraped stem and leaf portion further rearward. Providing a weeding device in front of the scraping device, wherein the weeding device has a plurality of weeding plates having a sharp tip;
And a weeding rod extending upward and backward from the weeding plate or its vicinity, so that the weeding rod is divided into the stem and leaf of the soybean besides the weeding plate, and the stem and leaf to be pulled out is not. Since the stem and leaf can be reliably separated, only the stem and leaf to be pulled out can be guided to the subsequent scraping device.

According to a second aspect of the present invention, a gauge wheel and a traveling wheel are arranged before and after the green soybean harvester according to the first aspect, and the weeding rod is extended and contracted from the vicinity of the gauge wheel to the side of the traveling wheel. Because it is freely installed, the height of the central part in the front and rear length can be changed and adjusted arbitrarily in combination with a change adjustment tool, etc. Even if the stem and leaf portion of soybean grown to an arbitrary height, this can be harvested by the aircraft During running, it can be accurately pushed laterally outward from the gauge wheel or the left running wheel to prevent the stem lobe from getting entangled with the side surface of the left running wheel and its peripheral members.

According to a third aspect of the present invention, among the weeding rods of the first aspect, the weeding rod facing the transporting portion side of the nipping and transporting device has an extension height higher than that of the weeding rod on the opposite side. In addition, since the tip of the weeding board is configured to be visible, when the tip of the weeding board is viewed from the steering wheel side, it is possible to prevent the line of sight from being obstructed by the overgrown stem lobes. .

As described in claim 4, claim 1 or claim 2
Alternatively, the weeding plate according to claim 3 is provided with a fuselage positioning reference weeding plate for indicating the action center of the scraping device and the nipping and conveying device, and the fuselage positioning reference weeding plate is used for another plant. It is smaller than the weed board, and the tip of the weed board is configured to be visible, so when viewing the tip of the weed board from the steering handle side, the weed board itself blocks the line of sight. Can be avoided.
