2. Description of the Related Art Japanese Patent Application Laid-Open No. 9-
There is one disclosed in Japanese Patent No. 84427 and the like, and this harvester is of a walk type, and from its front part, a weeding device, a scraping device, a leaf gripping transfer device, a neck gripping transfer device, a leaf cutting device, It is equipped with an aligning device, etc., the leaves of crops vegetated in the field (ridge) are weeded by a weeding device, and then scraped by a scraping device, and then the leaves are sandwiched by a sandwiching and transferring device. While pulling out by pulling it by moving it upward while holding it, cut the leaf part by the cutting device with the neck pinching and transferring device positioned while sandwiching the neck part, and then drop with the bulb part (ball) aligned in the field However, the crops in this field are collected and bound in a post process.

The crops harvested by this kind of harvester are usually four-row planted in the ridges, and the harvesting work is carried out in two steps.
The most common form is harvesting the remaining two articles during the return stroke. Also, this type of crop has a special vegetation form,
Since the leaves are intricately intertwined and it is a four-row plant,
Since the entanglement is more and more complicated, it is necessary to unravel the entanglement so that it can be easily scratched.

Therefore, the weeding device scoops up the foliage of the crop planted in the ridge and scoops up the foliage laid on the left and right, and scoops up the foliage scooped by the divider and circulates the claws to rake up. It has a scraping mechanism, and the divider is a plate material having a triangular shape in plan view.

[0005]

SUMMARY OF THE INVENTION In the above conventional technique,
Since the divider is a triangular plate, the rear part is wide,
When picking up a lodged crop, it moves unnecessarily in the left and right directions, which increases resistance and makes it difficult to improve weeding performance. According to the present invention, the outer surface of at least one of the bifurcated portions at the rear part of the divider is brought close to the outer surface of the grass transmission case of the scraping mechanism, so that the amount of protrusion of the outer surface of the divider is extremely reduced, and the crop is lying down. It is an object of the present invention to provide a weeding device for a harvester, which can be raised without increasing the amount of movement to the left or right and with a reduced resistance to improve the weeding performance.

[0006]

The first concrete means for solving the problems in the present invention is the crop B vegetated on the ridge A.

0 and a scraping mechanism 61 of a harvester having a scraping mechanism 61 that scoops up the foliage B1 scooped up by the divider 60 and circulates around a claw 23 and scrapes upward along a vertical plane in the traveling direction. The rear part of the descending divider 60 is formed in a bifurcated shape positioned with the scraping claw 23 interposed therebetween, and the outer surface of at least one of the bifurcated parts E of the divider 60 is the outer surface of the grass transmission case 19 of the scraping mechanism 61. That is, they are arranged close to each other in the left-right direction.

[0007] As a result, the amount of protrusion from the outer surface of the grass transmission case 19 of the divider 60 is extremely small, and the foliage B1 of the crop B that has fallen over is caused to move with little resistance to the left and right, and with less resistance. It is passed to the lifting mechanism 61. A second concrete means for solving the problem in the present invention is the divider 6 in addition to the first concrete means.
0 is a divider main body 60A that extends forward from the outer surface of the grass transmission case 19 and has a front end arranged in front of the scraping pawl 23, and a front end of the divider main body 6A in front of the scraping pawl 23.
0A and an auxiliary divider 60B having a rear end located on the front surface of the grass transmission case 19.

As a result, the amount of protrusion of the divider main body 60A and the auxiliary divider 60B from the outer surface of the grass transmission case 19 is extremely small, and in particular, the outer surface of the auxiliary divider 60B can be made flush with the outer surface of the grass transmission case 19 and fall down. The foliage B1 of the growing crop B is caused to move to the left and right without much resistance and with little resistance, and is delivered to the scraping mechanism 61.

A third concrete means for solving the problems in the present invention is, in addition to the second concrete means, at least one or both of the divider body 60A and the auxiliary divider 60B of the divider 60, and the lower portion is the ridge upper surface. It is formed of a plate material close to. As a result, the foliage B1 becomes the divider 6
It is possible to prevent falling from below 0 to the adjacent crop B side, and at the same time, to significantly increase the amount of protrusion of both or one of the divider main body 60A and the auxiliary divider 60B, while increasing the strength.

In addition to the above, the gauge wheel (driven wheel, front wheel) 3 is provided only on one of the left and right, in the figure, only on the right side.

From the front part to the rear part of the harvester 1, between the weeding device 4, the scraping device 5, the leaf sandwiching transfer device 6, the neck sandwiching transfer device 7, and the leaf sandwiching transfer device 6 and the neck sandwiching transfer device 7. Is mainly provided with a cutting device 8 and an aligning / discharging device 9 provided in the, and a pair of left and right subsoilers 10 for expanding and softening the ridges A are provided in the vicinity of the gauge wheel 3 for facilitating drawing. Each drive unit is linked to the engine 11.

The engine 11 is mounted on the rear portion of the machine frame 12 framed in a U shape in plan view.
The mission in the mission case 13 is directly connected to the output part of the. The missions in the mission case 13 are a mission of a traveling system and a mission of a work system (a power system such as a weeding device and a scraping device). The traveling system mission is a chain transmission in a pair of left and right transmission cases 14A, 14B. The drive wheels 2A and 2B are linked to the body and can travel and shift at a predetermined speed.

One of the pair of left and right transmission cases 14A and 14B, ie, the left transmission case 14B in the figure, is provided with a lateral expansion / contraction guide mechanism 15 and a telescopic transmission cylinder 16 having a nested structure provided in the rear portion of the machine frame 12. Expansion and contraction in the left and right direction
The tread can be freely adjusted according to the width of the ridge A shown in FIG.
A and 2B can roll on the furrow groove D.

The work system mission receives the power input to the weeding device 4 via the transmission shaft system 17 shown in FIGS. 1 and 2, and the transmission shaft system 17 is inclined forward and extends forward. The power is input to the scraping device 5, the leaf sandwiching and transferring device 6, and the like via a power distribution system 18 having a bevel gear or the like built in the shaft system 17. The weeding device 4 is
The divider 60 and the scraping mechanism 6 are arranged at a position sandwiching the two crops B.
1, each scraping mechanism 61 is provided with a weed transmission case 19 which is erected at the tip of the machine frame 12, and a sprocket wheel 20 which is rotatably supported around the upper and lower parts of the case 19 and rotates about the left and right axial centers. , 21, a chain 22 wound around the wheels 20, 21, and a lifting claw (tine) 2 attached so as to be vertically movable in the longitudinal direction of the chain 22.
3 and 3.

In the present example, the three grass transmission cases 19 are inclined downward in the front direction and are spaced from each other in the left-right direction. In this example, three pieces are arranged side by side. By circulating the chain 22 in the X direction shown in FIG.
By the scraping claws 23, the foliage B1 lying on the crop B in the left-right direction or the like is scooped vertically from the bottom so that the crops B can be aligned in the front-back direction (see FIG. 2). Each divider 60 extends forward from the outer surface of the grass transmission case 19 and has a divider body 60A whose front end is arranged in front of the scraping claw 23 and a front end which is attached to the divider body 60A in front of the scraping claw 23. And an auxiliary divider 60B whose rear end is located on the front surface of the grass transmission case 19 and the divider body 60.
It has a weeding rod 24 and the like provided on the upper edge of the front-down shape (back-up shape) of A and extending forward (Fig.
4).

Although the rear end of the auxiliary divider 60B is not fixed to the grass transmission case 19, it may be fixed by a screw or the like.
The divider body 60A and the auxiliary divider 60B are both formed of a plate material, and one or both of them can be formed of a round bar material, but it is more secure to form at least one of them as a plate material. By forming the main body 60A with a plate material, the attachment to the grass transmission case 19 is strong.

The dividing rod 24 is formed of a round bar and is welded to the upper front edge of the divider body 60A. The dividing body 60A can scoop the foliage B1 by itself, but It is preferable to provide the rod 24 because the resistance to weeding is small and the ball portion B2 is not damaged. The divider body 60A is bolted to the grass transmission case 19 and the machine frame 12 at the rear portion thereof, and also serves as a mounting bracket for the grass transmission case 19. The divider main body 60A is provided with vertically long bolt holes, and is vertically adjustable with respect to the grass transmission case 19 and the like.

Divider body 60A and auxiliary divider 60
Of the B, at least the lower part of the divider body 60A is the ridge A
It is close to the upper surface and surely separates the left and right spaces so that one of the left and right foliage B1 does not fall down to the adjacent crop B side. In the vicinity of the rear portion of the divider 60 (on the front side of the attachment portion to the grass transmission case 19), the divider body 60A and the auxiliary divider 60B are bent in the opposite directions, and
Further, a shaped portion E is formed, and the bifurcated portion E surrounds the scraping claw 23 projecting from the grass transmission case 19 from both left and right sides.

Divider main body 60A and auxiliary divider 60
B has both front and rear ends parallel to each other and an inclined portion in the middle, but the inclined angle of this inclined portion is set small,
Since the divider body 60A is fixed to the outer surface of the grass transmission case 19, the outer surface thereof projects by the thickness of the plate, but the outer surface of the auxiliary divider 60B is substantially flush with the outer surface of the grass transmission case 19. In addition to the fact that the left and right outer surfaces of the bifurcated portion E are as close as possible to the outer surface of the grass transmission case 19, the inclination angle of the inclined portion is set small, and the divider is also added. The 60 does not push the leaves B1 of the crop B too much, and does not give great resistance to the leaves B1.

The divider 60 is designed to guide the foliage B1 to the scooping start portion of the scraping claw 23 by the ridge A.
The extension length of the bush rod 24 corresponding to the shoulder portion A2 is longer than that of the other bush rods 24 (which are almost in contact with the ridge A) (see FIG. 2), and it exceeds the shoulder portion A2. The foliage B1 that is hanging down and the foliage B1 that is lying on the line are gradually lifted.

That is, all of the dividing rods 24 of the three sets of dividers 60 project forward and downward from the divider body 60A, and their tips are arranged below the upper surface of the ridge A so that they are attached to the upper surface of the ridge A. It is preferable to surely scoop up the foliage B1 that is present, but since the resistance becomes too large, here, only the dividing rod 24 of the divider 60 on the furrow groove D side corresponding to the shoulder portion A2 of the furrow A, It is formed to be longer than the tip of the shunting rod 24 on the center side of the ridge which is almost in contact with the other ridges A, and the tip of this shunting rod 24 is in contact with the ridge middle abdomen facing the ridge groove D.

The weed transmission case 19 of the weeding device 4 is
As shown in FIG. 2 and FIG. 3, the stem A2 of the ridge A and the streak B1 of the crop B, which correspond respectively to the two striations of the ridge A, hang down from the shoulder A2 and the streak B1. By scooping up the foliage B1 lying down on each other with the scraping claws 23, the foliage B1 oriented in the left-right direction is aligned in the front-rear direction.

The divider 60, especially the sward rod 24, extends from the vicinity of the lower portion of each sprocket transmission case 19 in a forward downward slope, and is oriented in the left-right direction in preparation for scooping by the scraping claws 23. Is gradually lifted and weeded. In addition, the sward rod 24 corresponding to the shoulder portion A2 is provided with a sward cover 25 that extends outward in the left-right direction and is bent in the shape of a "he" in a side view. 25 is designed to cover the gauge wheel 3 from the front and the upper side, and prevents the long stoop B1 that has been laid down being lifted by the sward bar 24 and re-laid down, and being stepped on by the gauge wheel 3. is doing.

That is, the weeding device 4 has the foliage B1 lying on the ridge A when the harvester 1 is run along the ridge A.
With the divider 60 and lift the claws 2
By scooping up (paying up) with 3, the foliage B1 is shaped in the front-back direction as shown in FIG. Reference numeral 4 is for laying the foliage B1 of the crop B lying on the ridge A and intricately intertwined with each other in the front-back direction to prepare for the next scraping device 5.

As shown in FIG. 4, the scraping claw 23 is lifted by the divider 60 at the scraping start portion (lower wheel winding portion) of the scraping claw 23 at a distance H from the top surface of the ridge A. Scoop up foliage B1 and divide 6
When weeding right and left in the two-pronged portion E of 0, it reduces scooping of the foliage B1 with excessive force and prevents the crop B from being pulled out from the ridge A. Is there.

Although the chain 22 of the scraping mechanism 61 circulates at a slower speed (slow speed) than the scraping belt of the scraping device 5, the scraping claw 23 of the scraping mechanism 23 is wound at the lower winding portion. Since the peripheral speed is faster than the peripheral speed of the straight line of scraping (the part where the claw 23 stands up on the front side in FIG. 4), the divider 60 gradually loosens the entanglement of the foliage B1, and the scoop claw 23 cultivates the foliage B1. The excessive pulling up of the crop B is prevented, and the unexpected withdrawal of the crop B is prevented.

Raising claw 2 of raising mechanism 61 of weeding device 4
By arranging 3 in a chain 22 that runs circularly,
Even if the long and short stalks B1 are mixed, it is supposed that the grass is shaped properly, and when the scraping claw 23 is turned over from the upper winding part, the scraping claw 23 is almost along the chain 22 as shown in FIG. It is supposed to be laid down, and the foliage B1 immediately after the grass is trimmed in the front-rear direction from the left-right direction, with the front-rear interval between the weeding device 4 and the leaf part scraping device 5 following the weeding device 4 being as small as possible. It is designed to be able to scratch.

As shown in FIGS. 1 and 4, the scraping mechanism 61 of the weeding device 4 and the leaf scraping device 5 are inclined downward in the front direction (inclined in the rearward upward direction) with a front-rear interval. They are arranged in parallel with each other, and their vertical heights are substantially the same. As shown in FIGS. 2 and 3, the leaf scraping device 5 includes an endless running body 27, which is an endless belt extending over an upper driving pulley 26A and a lower driven pulley 26B.
It is configured to circulate freely and is surrounded by a pair of left and right transmission cases 28A and 28B. The endless running body 27 shown by an endless belt has a receding angle with respect to the running direction. It has projecting claws 28 that are inclined and arranged in a row, and the tips of the claws 28 intersect each other at the rear position corresponding to the central weed case of the weeding device 4, and here By lifting the two stalks and leaves B1 which are shaped by the weeding device 4 in the front-rear direction from the left and right sides in a squeezing manner, the leaves are sandwiched and transferred linearly (pull-out belt device). We have succeeded (passed) to 6 smoothly and reliably.

While the scraping claw 23 of the weeding device 4 is made of hard resin, the scraping claw 28 of the leaf scraping device 5 is made of a soft elastic material such as rubber and has a foliage. B1
Soft touch to prevent the pain of crop B as much as possible.
The scraping start portion of the leaf scraping device 5 (the driven pulley 26
(The winding part around B), the tip of the scraping claw 28 is the crop B.
Is located in the vicinity of the neck portion of the plant, and can be surely held in the right and left direction from the root portion of the foliage B1 that has been trimmed by the weeding device 4.

That is, the leaf part scraping device 5 circulates the endless rotating body 27 in the Y direction shown by the arrow in FIG. 3, so that the pair of left and right scraping claws 28 moves the two foliage B1 left and right. It is possible to lift it while holding it from the bottom, and even long and short stalks B1 can be surely stretched linearly and delivered to the succeeding leaf sandwiching and transferring device 6. Leaf clamping device 6
1, FIG. 4 and FIG. 6, each of a pair of left and right transmission cases 29 arranged as a front downward slope is provided with an upper drive pulley 30 and a lower driven pulley 3.
1 is pivotally supported, and transfer belts 32A and 32B represented by rubber belts are wound around both pulleys 30 and 31 so as to freely circulate.

The leaf gripping and transferring device 6 is arranged so as to be inclined rearward and upward toward the rear in the transfer direction from the pulling-out start portion of the front portion (the portion wound around the driven pulley 31).
Here, the leaf scraping device 5 is the pinching and transferring device 6
The rear uphill is larger than the rear uphill,
In the vicinity of the front scratching start site of the leaf scraping device 5, specifically, slightly above, the extraction start site of the leaf sandwiching and transferring device 6 is arranged in proximity.

By adopting such a structure, the roll roller F at the start point of pulling is widened as shown in FIG. 6, and the transfer belts 32A and 32B circulate in the Z direction shown in FIG. Since the range of action at the time of doing is widened, the foliage B1 can be reliably and smoothly clamped, and the pulling action following this is ensured, and since it is close to the leaf part scraping device 5, Foliage B elongated
The escape of 1 is prevented.

As shown in FIG. 2 and FIG. 4, the leaf discharging rotary body 33 exemplified by a star wheel is provided above and below the right end portion of the leaf gripping and transferring device 6 and is cutting waste. The leaves are dropped into the furrow groove D. Furthermore, as shown in FIG.
Since the scraping action portion of the scraping device 5 is located up to the middle of the transfer, the collapse of the long foliage B1 during the transfer is prevented.

A neck holding and transferring device (neck positioning device) 7 following the leaf holding and transferring device 6 is provided,
As shown in FIGS. 1, 2, 4, and 6, the neck clamping transfer device 7 is composed of a pair of left and right transfer belts 34A and 34B, and extends substantially horizontally in the transfer direction rearward from the front inheritance site.

6A and 36B are wound endlessly through tensions or guide pulleys 37A and 37B as shown in FIG. 6, and drive pulleys 35A and 35B are shown by arrows Q in FIG.
By rotationally driving in the direction, the crop B can be transferred to the rear, and in the middle of the transfer, the foliage B1 can be cut by the cutting device 8 leaving a predetermined length.

That is, when the foliage B1 stretched substantially linearly by the scraping device 5 is pinched by the transfer belts 32A, 32B of the leaf holding and transferring device 6 and transferred backward, the transfer belts 32A, 32B are used. Because of the backward slope, the two crops B are gradually pulled out from the ridge A. The pulling amount (pulling height) is such that the neck of the crop B is at the lower end edges of the transfer belts 34A, 34B. It is determined that the upward movement is restricted, and the foliage B1 is stretched over the transfer belts 32A and 32B of the leaf holding and transferring device 6 and the transfer belts 34A and 34B for holding the neck, so that both of The cutting device 8 arranged in the (triangular space) S is used to cut into pieces.

Here, since the inheritance starting portion (the winding portion of the drive pulleys 35A and 35B) of the neck portion nip transfer apparatus 7 is close to the vicinity of the extraction start portion of the leaf portion nip transfer apparatus 6, the pair of left and right sides is close to each other. Transfer belts 34A, 34B
The action range associated with the rotation in the direction of arrow Q is widened, so that the foliage B1 can be reliably introduced into the neck-nipped transfer device 7.

From the inheritance start portion to the position of the cutting device 8, the neck clamp transporting device 7 ensures the pull-out operation while extending the foliage B1 by the leaf clamp transporting device 6.
In the cutting device 8 and thereafter, since the neck portion is clamped and transferred to the rear side, as shown in FIG. 6, a pair of left and right transfer belts 34 are moved from the inheritance start portion toward the position of the cutting device 8.
The facing distance C between A and 34B is gradually narrowed, and the clamping force (tension) is weakened during this period, and after the cutting device 8, the pair of left and right transfer belts 34A and 34B are in close contact with each other to clamp the clamping force (tension). ) Has been strengthened,
The third problem described above is solved here.

The transfer belts 34A and 34B are the crop B.
Since the neck portion is clamped, it is desirable that a rubber belt is sprinkled with a sponge belt or the like in order to reduce pain at the neck contact portion. Next, a power transmission system for the raking device 5, the leaf-niping / conveying device 6 and the neck-nipting / conveying device 7 will be briefly described.
