Description

The present invention relates to a lighting device attached to a green soybean harvester used for harvesting green soybeans.

Conventionally, when harvesting legumes such as green soybeans and tea beans cultivated in a field, a machine is applied to the stem and leaf to remove the pods (pod removal) or a machine to cut the upper stem and leaf from the ground. Dehulling had to be done afterwards. However, in any case, the remaining stem leaves and stem roots cannot be left as they are, so that an operation for removing them is necessary. In the former case, in particular, the stem and leaf must be extracted together with the stem root, which is a very laborious operation. On the other hand, in the latter case, if the soil is plowed, the stem roots are plowed and inverted with the plowed soil, but there is a case where it is troublesome in the post work or the like.

A pair of left and right upper weeding rods 19c and 19d are extended rearward and upward in a rearward direction, and the tips of the weeding rods 19a to 19d are in the vicinity of the weeding plate 18a. It may be fixed to a location, and in the illustrated example, it is fixed to the back surface of the weeding plate 18a.

By the way, the stem and leaf portion 7a just before harvesting is very prosperous, and it is not possible to know where the weeds 18 and the like are traveling. Therefore, by raising the upper left weeding rod 19c coming out of the weeding plate 18a, and pushing the overgrown stem and leaf portion 7a to the left side effectively during the harvesting run of the body, the steering handle 5 is held. The operator can visually check the tip of the weeding plate 18a buried in the stem / leaf portion 7a group.

An upright member 2a is provided behind the weeding plate 18a in the same manner as the machine base 2, and the weeding plate 18a is supported by the uprighting member 2a via a suitable coupling member so that the position can be adjusted. ing. The stem-and-leaf portion 7a proliferating therearound tends to become entangled with the upright-shaped support member 2a during the harvesting run of the body. To prevent this, the weeding plate 18a is provided at the lower end of the upright-shaped member 2a. The parts behind the lower weeding rods 19a, 19b and the upper weeding rods 19c, 19d cover the parts and smoothly flow to the rear of the stem / leaf portion 7a during the harvesting movement of the body. The provided stem leaf excluding guide plate 18c is provided.

The left weeding plate 18b is relatively wide and long, and from this weeding plate 18b, a relatively short lower side which pushes the relatively lower part of the stem leaf part 7a to the right. The weeding rod 19e is extended rearward and upward. At this time, the tip of the weeding rod 19e may be fixed to a position near the weeding plate 18ba. It is fixed to a plate piece fixed to the back surface of the plate 18a. The weeding plate 18b is supported by a left standing member 2b provided in the same shape as the machine base 2, and the standing member 2b is directed rearward to a position above the lower weeding rod 19e. An upper weeding rod 19f is provided which extends upward and pushes a relatively lower portion of the stem / leaf portion 7a to the right.

In addition to the weeding device 11, weeding devices 11a and 11b related to the running wheel 1 and the gauge wheel 10 are provided.
The weeding device 11a related to the right traveling wheel 1 is provided at a front portion below the right traveling wheel 1 and forms a part of the transmission 4 to form a rotation center axis holding portion of the traveling wheel 1. A forward-facing support rod member 4b is fixed to the support rod member 4a, and a weeding plate 18d having substantially the same size as the weeding plate 18b is provided at the tip of the supporting rod member 4b. A plurality of weeding rods 19g and 19h are extended rearward and upwardly inclined, and contribute to preventing the stem and leaf portion 7a of green soybeans 7 from tangling with the right traveling wheel 1 during harvesting of the body. Things.

At this time, the weeding plate 18d is swingably supported around the fulcrum axis a via a left-right fulcrum axis a provided at the tip of the support rod member 4b, and the oscillating angle is a plurality of specific angles. It shall be fixed to any of the above.
The weeding rods 19g and 19h are fixed in the same shape as the weeding plate 18d, and one of the weeding rods 19g is provided so as to gradually protrude rightward and laterally toward the right rear of the right traveling wheel 1, The other one 19h is provided so as to gradually protrude leftward and leftward as it goes to the left rear of the right traveling wheel 1. At this time, the front ends of the weeding rods 19g and 19h are attached to the right traveling wheel 1h. The front end of the right weeding rod 19g is supported so as to be swingable about a substantially forward-backward axis, and these weeding rods 19g and 19h are moved during harvesting of the body. The stem and leaf portion 7a of the green soybean 7 is pushed right and left from the right running wheel 1 to prevent the stem and leaf portion 7a from becoming entangled with the side surface of the right running wheel 1 and its peripheral members.

The weeding device 11b related to the gauge wheel 10 includes a weeding plate 18e provided at a front position of the gauge wheel 10 and a weeding device 11b provided at a side of the machine body from a front portion of the gauge wheel 10 to a side portion of the left traveling wheel 1. It consists of grass rods 19i, and prevents the stem and leaf portion 7a of green soybeans 7 from getting entangled with the gauge wheel 10, the left running wheel 1, and the like during the harvest running of the body.

The weeding plate 18e extends the pair of left and right support plate members 10b forward and downward from the fork member 10a supported by the machine base 2 and bends them around the front half of the gauge wheel 10 to join the front portions thereof. An angle adjustment about this axis b is attached to this joint portion via a front-rearward axis b so as to prevent the stem / leaf portion 7a from tangling with the gauge wheel 10 during harvesting and running of the body.

The weeding rod 19i is obtained by fitting a rear rod member c2 to the front rod member c1 so as to be extendable and retractable. At the same time, the rear end of the rear side rod member c2 is mounted on the side of the machine base 2 via the adjustment device d for changing the swing angle position about the substantially front-rearward axis, and swings about the substantially forward-rearward axis. By changing the position, the height of the central portion of the fore-and-aft length can be arbitrarily changed and adjusted, and the edible soybean 7 grown to an arbitrary height can be changed by changing the swinging position about a substantially forward-backward axis. Even when the trunk / leaf portion 7a is pressed, it is accurately pushed laterally outward from the gauge wheel 10 or the left traveling wheel 1 during harvesting travel of the body, so that the stem / leaf portion 7a is applied to the side surface portion of the left traveling wheel 1 and its peripheral members. It is intended to prevent entanglement.
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 transporting 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 left and right pair of projecting belts 21 stretched between a pair of upper and lower pulleys (not shown). Both the opposing surfaces are rotated backward in the front-low-back high-inclination plane, and the stem-leaf portion 7a to be pulled out is lifted up by the belt 21 with projections and guided to the subsequent nipping and transporting device 13. Therefore, the center of the belt 21 with the projections opposed thereto 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 projection-attached belt 21 to prevent the stem / leaf portion 7a from biting. The cover 22 is positioned so as not to obstruct the line of sight e when the operator holding the operation handle 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 includes a pair of left and right belt conveyance units 13a having an elastic belt 23 stretched between a pair of upper and lower pulleys (not shown). , 13b are formed, and the opposing surfaces of the left and right elastic belts 23 of the conveying portions 13a, 13b are pressed against each other, and are rotated rearward in a front-rear-lower-high-inclined plane. It is positioned so as not to pinch the multi-film 45 covered with the ridges 6 so as to be in close contact with the ground, so as to pinch only a part or a part of a range of about 10 cm or less from the ground at the lower end of the stem of the soybean 7. And the front and rear positions are substantially coincident with the rotation center of the gauge wheel 10, and the lower end portion of the stem lobe 7a squeezed by the squeezing device 12 is clamped by the elastic belt 23 and pulled out from the ground, and Back upper It is intended to convey to. Here, the nipping and transporting 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. In addition, the fact that the front and rear positions of the nipping and conveying start end f are substantially coincident with the rotation center of the gauge wheel 10 means that the gauge wheel 10 moves the nipping and conveying start end f to the same height as before the inclination even when the machine body is inclined with respect to the ridge 6. It is made possible to hold the information. The pressing force of the elastic belt 23 is set so as to exert a force enough to pull out the underground shoot root 7b in a state where the stem and leaf portion 7a is sandwiched. Since 7c must not be crushed, a soft elastic body such as 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 in the vicinity of the starting end of the nipping and conveying device 13 and mainly includes a vibrating blade 25 having an inverted L-shape in front view with a vertical portion 25a and a horizontal portion 25b. The lower soil is loosened to make it easier to pull out the stem lobe 7a. In this case, the soil below the root 7b is loosened by the vibrating device 14 before the stem-and-leaf portion 7a is subjected to the pulling-out action by the holding and conveying device 13. The vertical portion 25a is rotatably supported on the body 2 and the like by a pin 26, and a crank rod 27 is connected to an upper portion of the vertical portion 25a to be vibrated back and forth. The lateral portion 25b of the vibrating blade 25 is inserted from the bottom of the end of the ridge 6 and extends to the lower part of the stem root 7b of the drawn stem / leaf portion 7a. The root 7b is brought close to or directly in contact with the root 7b to ensure easy pull-out. 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 strong 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 has a toothed drum 28 that is rotated with its central axis included in a vertical plane, and a rubber plate provided to face the drum 28. 29, which acts on the root 7b being conveyed by the nipping / conveying device 13 to remove soil attached thereto. FIG. 5 is a sectional view taken along the line A of FIG. 1 and FIG. 6 is a sectional view taken along the line BB of FIG. 1, and the toothed drum 28 has a form like a drum of a threshing machine. In addition, a drum 31 projects rotatably forward from a housing 30 accommodating a transmission structure, and toothing 32 is implanted on the outer periphery of the drum 31. A rubber plate 29 is provided at a position within the range of operation of the tooth handling 32. Even if the tooth handling 32 hits 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 in parallel with the transfer direction in a plan view, but in a cross state in which the front opens or the rear opens in a side view. Is set to The reason is that the soil is gradually removed from the roots 7b and acts on all the roots 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 to the tooth handling 32 in the longitudinal direction, so that even if the soil adheres as a lump A to the root 7b, the tapping rod 32a is broken. . Even if the broken root 7b is to be wound around the toothed drum 28, the striking rod 32a is located at a position distant from the drum 31 in the radial direction, so that it is difficult to wind, and even if it is wound, it is easy to remove. .

The lateral guidance device 16 is provided at the transport end of the belt transport unit 13b on the left side of the nipping and transporting device 13, and guides the green soybeans transported by the nipping and transporting device 13 to the collecting device 17, and FIG. FIG. 8 is a cross-sectional side view showing a main part of the device 16, and FIG. 8 is a view taken in the direction of the arrow C in FIG. 7. A feed claw 34a is protruded from the outer periphery of the drum 33 and a feed claw 34 is superposed in a step-like manner. 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 D-D of FIG. 7. The feed claw 34 is formed in a ring shape as a whole, and an inner hole 34 b is fitted to the drum 33 and fixed. The relative displacement is regulated by fitting a plurality of projections 34c formed on the inner peripheral surface of the inner hole 34b into through holes formed in the drum 33.

At the same position as the transfer surface of the left elastic belt 23, there is provided a guide plate 35 which rises to the height of the uppermost feed claw 34, circulates around the outside of the drum 33, and extends to the left. A stem leaf guide rod 36 is provided which goes out of the same portion 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 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 has a front-rearward portion that pushes the stem-leaf portion 7 a conveyed by the holding / conveying device 13 to the left until reaching the lateral guiding device 16. It has the function of sending.

The guide plate 35 also serves as a cover 35a that covers the top of the uppermost feed claw 34. When the stem lobe 7a goes around, the pod 7c hangs down on the stem and the pod 7c comes off, or the trunk lobe 7a is removed. 7a is prevented from winding 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. As a result, the stem-and-leaf portion 7a conveyed by the nipping 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 forcibly forced to the left by the claw 34a of the feed claw 34. Is wrapped around.

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 portion 7a discharged from the guiding route 38 thereon. is there. 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).

作業 Each of the above working units 3 is driven by the transmission unit 4, and 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 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 wheels 1.

On the other hand, in 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 nipping and conveying device 13 to rotate the elastic belt 23. The left side of the upper pulley shaft protrudes upward, and the drum 33 and the feed claw 34 are fitted to this and also driven. Further, power is transmitted from an appropriate roller that stretches the elastic belt 23 to an upper pulley shaft of the belt 21 with a projection of the scraping device 12, thereby rotating the belt 21 with a projection. Further, the power transmitted to the transmission unit 4 drives the crank rod 27 that vibrates the vibrating blade 25 of the vibrating device 14 along an appropriate driving path, and also drives the drum 28 with the protrusion of the soil removal device 15.

ゲ ー ト 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. 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 transport surface of the stem-and-leaf portion 7a (the mating surface of the elastic belt 23 of the nipping and transporting device 13). It is conveyed backward through 42. Therefore, the gate 42 is set to a height that does not hinder the conveyance of the stem / leaf portion 7a. Although the gauge wheel 10 is provided on the left side of the body 2 as described above, the gauge wheel 10 naturally moves up and down together with the fork member 10a with the handle 44 in the storage tube 43 fixed to the body 2. The height of the working unit 3 is set by this. The fork member 10a is provided with a scraper 10c for scraping off the soil and the like adhering to the gauge wheel 10 in a downwardly inclined manner, and the gauge wheel 10 travels in the ridge groove 6b where 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 unit 3 is not disturbed by the adhesion of the earth and sand. At this time, the fact that the scraper 10c is made to fall down in the forward direction not only promotes the fall of the scraped earth and sand, but also contributes to preventing the stem leaf 7a from being caught.

The height of the working unit 3 is adjusted so that the tip of the weeding plate 18 of the weeding device 11 is kept close to the ridge top 6a. However, when the ridge 6a is covered with the multi-film 45, the interval is set such 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 harvested strip of 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 in the stem and leaf portion. The multi-film thus prevented from being damaged 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. Is

Furthermore, illumination means 47 for illuminating each working unit 3 is provided. The illuminating means 47 includes an illuminating lamp 47a for irradiating the tip of the weeding plate 18a on one side, and an illuminating lamp 47b capable of changing the irradiating direction so as to irradiate the collection device 17 and other parts. And 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. The usage of these lamps 47a and 47b is appropriately changed between single row and single row planting and single row and double row planting. In the case of single row single row planting, the tip of the right weeding plate 18a is not seen. Therefore, the former illumination lamp 47a does not have to be turned on. In this case, the latter illumination lamp 47b irradiates the tip portion of the holding and conveying device 13 and the collection device 17, while the other illumination lamp 47b emits light. In the case of double-row planting, the tip of the right weeding plate 18a and the collecting device 17 are irradiated.

In the above-described embodiment, the weeding rod 19c and the stem leaf guiding rod 36 constitute stem leaf guiding means, and the stem and leaf portion that passes between the left and right weeding boards 18a and 18b during harvesting. 7a is firstly pushed to the left while being moved backward by the weeding rod 19c, and further pushed to the left even after being pinched by the pinching / conveying device 13, after which it is conveyed by the pinching / conveying device 13. When the trailing end of the weeding rod 19c approaches the rear end of the weeding rod 19c, it is conveyed while being pushed to the left by the stem-and-leaf guide rod 36, and finally guided laterally outward by the lateral guiding device 16 to be placed on the collecting device 17. Be dropped. While such harvesting is being performed, 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 along 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 and the like with thick stem and leaf portions 7a, the pilot can always accurately see the tip of the weeding board 18a during harvesting. The part 3 can be made to act optimally on the row of green soybeans.

In carrying out the above harvesting, the small weeding plate 18a means that the weeding plate 18a itself blocks the driver's line of sight e when the operator with the steering wheel 5 looks at the tip of the weeding plate 18a. It is effective in preventing the situation, and the pair of left and right lower weeding rods 19a and 19b and the pair of left and right upper weeding rods 19c and 19d reduce the weeding ability due to the small weeding plate 18a. These weeding rods 19a to 19d provide a gap between them, thereby facilitating the passage of the operator's line of sight e when seeing the tip of the weeding plate 18a, and achieving an accurate harvesting process. It is one that contributes to performing.

The gap between the upper weeding rods 19c and 19d and the lower weeding rods 19a and 19b may cause passage of the stem leaf part 7a backward on the one hand. In this case, the stem leaf is excluded. The guide plate 18c smoothly guides the stem leaf portion 7a passing obliquely rearward, so that a situation in which the stem leaf portion 7a is entangled with the lower end portion of the standing member 2a is prevented.

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, the illumination lamp 47a intensively irradiates the tip of the right weeding plate 18a. Therefore, the pilot can drive accurately even in the case of two-row single-row planting. Further, since the collecting device 17 can be intensively illuminated by another illuminating lamp 47b, the operator can visually confirm the accumulated state of the harvested green soybeans on the collecting device 17 at any necessary time, and can accurately determine the harvested green soybeans. Processing can be performed. If necessary, the irradiation angles of the illumination lamps 47a and 47b may be changed to illuminate an arbitrary location.

The weeding plate 18e in front of the gauge wheel 10 scoops up the stem and leaf portion 7a that has grown in the ridge groove 6b and feeds it to the upper edge of the support plate member 10b during harvesting and running of the body. The support plate member 10b abuts 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 outside by the weeding action of the weeding rod 19i. The weeding rod 19i moves the stem leaf 7a on the front outer side thereof, the weeding board 18b, the weeding board 18e, and the stem leaf part 7a sent obliquely rearward from the support plate member 10b toward the rear. The stem leaf portion 7a is prevented from entangled with the gauge wheel 10 and the left running wheel 1 gradually.

The weeding plate 18d is used to push the vegetation green soybeans to the left and right in front of the right running wheel 1 during the harvesting operation of the aircraft and to send them to the outside of the right and left weeding rods 19g and 19h. From entangled with the right traveling wheel 1 and the rotation center shaft holding portion 4a. At this time, the swinging operation of the weeding rod 19g about the axis in the front-rear direction changes the height at which the weeding rod 19g is pressed against the stem and leaf portion 7a, and adapts to various growing heights of green soybeans. Also, by changing the posture of the weeding plate 18d about the horizontal axis a together with the weeding rods 19g and 19h, the action range of the weeding plate 18d and the weeding rods 19g and 19h on the vegetated green soybeans is changed. It will adapt to various growth heights.
