Description

  The present invention relates to a self-propelled crop harvesting auxiliary machine for solving soil around roots such as root vegetables, bulbs, tubers and the like to facilitate harvesting work.

  Conventionally, as a crop harvesting auxiliary machine for assisting harvesting operations such as rhizome crops and house-grown vegetables, first the root cutting blade (soiler) vibrates back and forth to cut the roots of the rhizome crops, and the roots are cut off The crops are pulled out by the conveyor that holds the foliage and transported backward, and the foliage of the crops is cut by a cutting device equipped with a cutter, etc., and then stored in a storage device such as a container to prepare for the container unit. There is one that is discharged onto the basket after harvesting crops by a discharge conveyor.

  Further, in order to prevent the harvested crops from being discharged onto the multifilm when the straw is covered with the multifilm, according to the following Patent Document 1, the extraction is performed by pinching the crop root and the foliage. In a crop harvesting device that consists of a conveyor, cutting section that cuts the foliage of the crop, and a storage section that stores the crop, the storage section can store a certain amount of crop, and the stored crop can be planted. A harvesting device provided with a discharge device that can discharge to the outside of the machine body in a direction perpendicular to the straw is disclosed. In addition, the stalks and leaves of the cut crop are also discharged to the outside of the machine body in the direction orthogonal to the crop planting ridge.

  With the harvesting device of the above-mentioned Patent Document 1, the stored crop can be discharged into the uncovered portion of the multi-film between the adjacent straws by the conveyor or the straw after removing the multi-film after harvesting. The remaining multifilm can be removed without being affected by the harvested crop.

  Further, the harvesting device of Patent Document 1 is attached to the rear part of a tractor or the like, pulled, and transported by removing the surrounding soil from below the crop (garlic, onion, etc.) with a root cutting blade provided in front of the aircraft. It is drawn and harvested at the conveyor section. The harvesting device of this Patent Document 1 is almost the same as a shoe (the one for stabilizing the crop extraction position, which is arranged at the left and right of the position of the crop planting intercostal groove portion) in which the action part of the root cutting blade is in parallel with the field scene. Because it is at the same height position, it is difficult to unravel the straw in a field where the height of the straw is low, such as a flat straw, and it takes a lot of labor to collect the crop from the straw and burdens the operator. . In addition, there is a problem in that the commercial value of the crop is reduced due to contact of the root cutting blade with crops such as spinach, potato, ginger and garlic.

  Moreover, with the self-propelled harvesting apparatus of Patent Document 2, when the drive wheel is self-propelled, the leafy vegetables cultivated in the straw along with the advancement of the self-propelled harvesting apparatus with the blade having an oblique blade span including the vine planting width W Can be cut at once for each planting width W directly under the ground surface. Further, since the vehicle width of the self-propelled harvesting device is about the same as the vine planting width W, it is also suitable for use in a plastic house or a relatively narrow farm field.

  However, in the self-propelled harvesting device of Patent Document 2 described above, since the blade that cuts the root portion and leaf portion of a crop (such as spinach) has an oblique blade span in plan view, the front and rear direction from the rear portion of the management machine on which the engine is mounted. Since the blades are arranged over a wide area and take up space, the self-propelled harvesting device itself is also increased in size.

  In addition, since the blade that cuts the root portion and leaf portion of the crop in this way has a blade span that is oblique with respect to the traveling direction in plan view, the distance from the drive wheel is increased on the rear side of the blade, and earth and sand are placed on the blade. When resistance is applied, the driving force of the driving wheel may not push the roots of the leafy vegetables, or the advancement of the harvesting device may be hindered and the progress may be stopped.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a left side view of a crop harvesting auxiliary machine according to an embodiment of the present invention, and FIG. 2 shows a plan view of the crop harvesting auxiliary machine of FIG. Further, FIG. 3 shows a simplified view of the vicinity of the U-shaped soira 7 of the crop harvesting auxiliary machine of FIG. 1 as viewed from the front.
The crop harvesting auxiliary machine 1 according to an embodiment of the present invention is used for harvesting assistance to make it easier to manually harvest root vegetables such as carrots and garlic, tubers, and leafy vegetables such as spinach that are vegetated on the ridge A. It is a work machine.

The crop harvesting auxiliary machine 1 supports the main frame 4 so that the front wheels 2 and 2 on the left and right can be driven wheels and the left and right rear wheels 3 and 3 can be used as auxiliary wheels and can be driven on the front wheels across the heel A. Between the frame 4 and the cover 20, an engine 5 as a drive source and a transmission (transmission case) 5a for shifting the power of the engine 5 are provided to constitute a four-wheel self-propelled vehicle. The main frame 4 is disposed directly below the engine 5 in order to ensure a clearance (referring to a “space” between the bottom of the main frame 4 and the apex of the ridge A). Further, the left and right handles 6 and 6 are extended above the engine 5 to the rear of the machine body in order to ensure turning operability.
The left and right front wheels 2 and 2 support the main frame 4 with left and right transmission cases (chain cases) 2a and 2a receiving power from the transmission 5a as support legs, respectively, and the engine 5 is supported by the front wheels 2 and 2 and the rear wheels 3 and 3 Place between.

With the above configuration, the output shaft of the transmission 5a, the front wheels 2, 2 and the rear wheels 3, 3 are arranged in a triangular shape in a side view, so that the weight of the airframe is evenly distributed and the balance of the airframe is improved.
And, a U-shaped soiler (a thawing member) is used between the front wheels 2, 2 and the rear wheels 3, 3 and below the engine 5, preferably at a position directly below the crop A from the bottom of the crop. ) If 7 is provided, the balance can be further improved.

  The U-shaped soiler 7 extends in the vehicle width direction (the left-right direction of the machine body), and is formed with blades (soil-disassembling blades) 7a for digging out the ridge A across the thin plate leading edge, The suspension plates 7b and 7b are attached to the main frame 4 and supported by suspension.

The U-shaped soiler 7 supports the left and right suspension plates 7b, 7b by movable fulcrums 7c, 7c, and an eccentric cam (see FIG. 5) near the movable fulcrum 7c on one side (right side in the illustrated example). By connecting a rocking rod 7d that vibrates with a non-illustrated structure to constitute a soli drive unit, a simple vibration soiler can be constructed. The length of the swing rod 7d can be changed by changing the connecting portion with the suspension plate 7b.
And by setting the height position of the blade 7a of the U-shaped soiler 7 to a height position below the ground contact surface (travel path B of the working machine) of the front wheels 2, 2 and the rear wheels 3, 3, Even in a farm field where the vertical height of cocoon A is low (eg, flat cocoons), the surrounding earth and sand can be reliably unwound from below the crops such as spinach, garlic, and gold carrot.

Therefore, the blade 7a is prevented from coming into contact with the crop and damaging the crop, and the quality of the crop is maintained. And since 畝 A is surely solved, the worker can recover the crop from 畝 A with a light labor, so that the labor of the worker is reduced and the work efficiency is improved.
At this time, even if the U-shaped soiler 7 is in the planting culture, the front wheels 2 and 2 that are driving wheels are arranged on the front side of the machine body and on the front side of the machine body of the U-shaped soyer 7. , 2 and travels forward, so that a strong traction force is applied, so that the U-shaped soiler 7 can turn almost without any trouble even when it receives resistance of earth and sand when unraveling the ridge A. Accordingly, the forward movement of the crop harvesting auxiliary machine is prevented from being stopped or stopped, and the work efficiency is improved.

  And when the crop harvesting auxiliary machine 1 of this embodiment self-travels across the ridge A, the blade 7a of the U-shaped soiler 7 acts on the base of the ridge A to unravel the surrounding soil from below the crop. Therefore, the worker can easily pick up the leaf vegetables such as spinach, tubers such as garlic, root vegetables such as Kinki carrots etc. The labor required when a person pulls out the above-mentioned crops is greatly reduced, and the crop roots and stems and leaves are prevented from being broken and the product value of the crops is improved. .

  Further, by providing a U-shaped soiler 7 between the front wheels 2, 2 and the rear wheels 3, 3 and below the engine 5, a space between these front wheels 2, 2, rear wheels 3, 3 and the engine 5 is provided. The crop harvesting auxiliary machine 1 can be made compact, and the distance between the front wheels 2 and 2 that are drive wheels and the U-shaped soyer 7 is close, so that resistance to earth and sand is applied to the blade 7a. Even in this case, the roots of leaf vegetables can be pushed out by the driving force of the front wheels 2 and 2.

Further, in order to cut the foliage portion of the crop before the U-shaped soiler 7 acts, a foliage cutting device 12 is provided in front of the U-shaped soiler 7 and in front of the front wheels 2 and 2.
The foliage cutting device 12 mounts a reciprocating cutter 13 that is longer than the left and right width of the ridge A on a cutter support portion 17 so as to simultaneously cut the stem portions of a multi-row planted crop, and the cutter support portion 17 is parallel to the cutter support portion 17. The height of the reciprocating cutter 13 is maintained while the posture of the reciprocating cutter 13 is maintained by an adjustment lever 14a that is supported by the left and right support arms 14 and 14 by links and extends rearward from the support arm 14 on one side (left side in the illustrated example) via the support column 14b. Configure as possible. A driving motor 47 that supplies driving force to the reciprocating cutter 13 is attached to the outside of the main frame 4 so as not to interfere with the foliage. The drive motor 47 may be replaced with a second engine that is a drive source different from the engine 5. The drive motor 47 may be hydraulic or electric.

  A reciprocating cutter 13 of the foliage cutting device 12 divides the ground foliage part and the root part in the ground, and the U-shaped soyler 7 unravels the ridge A around the crop from below the crop. It should be noted that by making the reciprocating cutter 13 detachable, it is better to leave the root part until shipment, such as spinach (the crop activity deteriorates because the activity of the crop is maintained if the root part remains) Can be harvested without splitting the root and leaves.

  The crop harvesting auxiliary machine 1 having the above configuration is provided with a severing and cutting device 12 including a reciprocating cutter 13 that is horizontally longer than the left and right widths of the ridge A before the front wheels 2 and 2. Since the stems and leaves are cut in front of the front wheels 2 and 2, work troubles caused by large foliage such as garlic can be suppressed, so it is possible to efficiently harvest tuber crops such as garlic and root vegetable crops such as gold carrots. It can be carried out.

  In addition, the foliage cutting device 12 comprising the reciprocating cutter 13 is supported by the left and right support arms 14 and 14, and the adjusting lever 14a for adjusting the cutting height of the reciprocating cutter 13 is provided. Since it can be adjusted to an appropriate height with respect to the height of the leaf, when cutting leafy vegetables such as spinach, the root and foliage can be cut at the border, preventing damage to the edible foliage. Therefore, the commercial value of the crop is improved.

On the other hand, when harvesting tubers such as garlic and root vegetables such as Kinki ginseng, the operator can harvest only the root by adjusting the height of the reciprocating cutter 13 to the boundary between the root of the crop and the foliage. Therefore, the work of cutting off the foliage after harvesting is omitted, and the labor of the operator is reduced.
Also, if the height of the reciprocating cutter 13 is adjusted slightly above the boundary between the root and the foliage, some foliage will remain at the root of the crop that remains in the cracked heel A, so that the operator will leave the remaining foliage. The crop can be pulled out from the ridge A by grasping the part, and the work efficiency is improved.

Further, it is preferable that the depth of the U-shaped soiler 7 in the soil of the blade 7a can be adjusted. By adjusting the depth of the blade 7a of the U-shaped soiler 7, the heel A can be unraveled from the bottom of the crop more reliably, and the crop can be prevented from being damaged, so that the quality of the crop can be maintained.
For example, if the depth adjustment switch 15 of the U-shaped soiler 7 is provided in the vicinity of the handle 6, the depth can be adjusted even while the crop harvesting auxiliary machine is being operated. If the depth adjustment switch 15 is at a position away from the periphery of the handle 6, the operator must move from the vicinity of the handle 6 every time the depth of the U-shaped soiler 7 is adjusted. The labor of the person is reduced.

Furthermore, if the moving direction of the U-shaped soiler 7 (the moving direction of the upper part (connecting portion) 7e) and the direction in which the depth adjusting switch 15 is tilted are the same, it is possible to reduce the operator's mistake in adjusting the depth. .
As shown in FIG. 2, one end of a cylinder 21 for operating the U-shaped soiler 7 is attached to the left and right sides of the main frame 4, and the rear end of the piston 22 that moves in the cylinder 21 in the front-rear direction is provided. It is attached by being fixed to the suspension plate 7b.

  A cylinder / lever connection cable 30 is connected to the depth adjustment switch 15, and a signal generated by operating the depth adjustment switch 15 is sent to a solenoid valve (not shown) via the connection cable 30. The solenoid valve of the hydraulic circuit of the hydraulic cylinder 21 is operated based on the signal sent to the solenoid valve, and the hydraulic cylinder 21 is operated. Instead of the hydraulic cylinder 21, another actuator such as an air cylinder or an electric cylinder may be used.

  When the depth adjustment switch 15 is operated, a signal from the depth adjustment switch 15 is transmitted from the cylinder / lever connection cable 30 to the cylinder 21 and the piston 22 moves. When the depth adjustment switch 15 is tilted in the direction of arrow A (FIG. 1), the piston 22 in the cylinder 21 extends and moves in the direction of arrow C in FIG. On the other hand, when the depth adjustment switch 15 is tilted in the direction opposite to the arrow A direction, the piston 22 in the cylinder 21 contracts and moves in the direction (forward) opposite to the arrow C direction.

Therefore, when the depth adjustment switch 15 is tilted in the direction of arrow A, the suspension plates 7b and 7b of the U-shaped soiler 7 rotate in the direction of arrow B about the movable fulcrums 7c and 7c, and the blade 7a moves forward. For this reason, the blade 7a scoops the earth and sand and dives into the soil, so that the dive depth becomes deeper.
On the other hand, when the depth adjustment switch 15 is tilted in the direction opposite to the arrow A direction, the suspension plates 7b and 7b of the U-shaped soiler 7 rotate in the direction opposite to the arrow B direction around the movable fulcrums 7c and 7c. Then, since the blade 7a moves backward, the dive depth becomes shallow when the blade 7a comes out of the soil.

In this way, when the piston 22 in the cylinder 21 extends and moves in the direction of arrow C (rearward), the depth of submergence of the blade 7a increases, and the piston 22 in the cylinder 21 contracts to the direction opposite to the direction of arrow C (frontward). ), The dive depth of the blade 7a becomes shallower.
Therefore, when a scale 25 is provided on a surface parallel to the longitudinal direction of the piston 22 of the main frame 4 and a scale corresponding marker 23 (attached to the piston 22) is attached to the piston 22, the piston 22 moves in the longitudinal direction. By reading the scale 25 where the marker 23 is located, the operator can easily know the depth of the blade 7 a while operating the depth adjustment switch 15. Since the scale 25 provided on the main frame 4 is on the outer side of the machine body than the handle 6, it is easy for the operator to see.
Specifically, as shown by a round frame portion X in FIG. 2, a character such as “depth” on the rear side of the scale 25 of the main frame 4 and “shallow” on the front side may be written. , Symbols, alphabets, scale thickness, length, color, etc. may be changed.

  Therefore, by adopting this configuration, the depth of the blade 7a of the U-shaped soiler 7 can be easily adjusted by the depth adjustment switch 15 as well as the operation of the handle 6, and the depth of the blade 7a can be adjusted while performing this operation. By knowing at a glance, 目 A can be solved more reliably and efficiently from below the crop. Therefore, since the crop can be prevented from being damaged, the quality of the crop can be maintained. Further, if the direction in which the depth adjustment switch 15 is tilted and the operation direction of the upper part (connecting portion) 7e of the U-shaped soiler 7 are the same, it is possible to reduce an operator's mistake in adjusting the depth and improve work efficiency. .

Furthermore, the swing rod 7d may be configured so that the length of the slide can be changed in accordance with the expansion and contraction of the cylinder 21 by the operation of the depth adjustment switch (lever) 15.
The swing rod 7d can be easily configured by being slidably mounted in the cylindrical boss 8 (FIGS. 2 and 8). When the cylinder 21 for operating the U-shaped soiler 7 is expanded and contracted, the suspension plate 7 b fixed to the tip of the piston 22 of the cylinder 21 moves in the front-rear direction in accordance with the movement of the piston 22.

  For example, when the adjustment lever 15 is tilted in the direction of arrow A, the cylinder 21 extends and the U-shaped solitary upper portion 7e moves rearward (in the direction of arrow C). Therefore, the rocking rod 7d also moves backward in the boss 8 in conjunction with the movement of the U-shaped solier upper portion 7e. On the other hand, when the adjustment lever 15 is tilted in the direction opposite to the arrow A direction, the cylinder 21 contracts and the U-shaped solier upper portion 7e moves forward (the direction opposite to the arrow C direction). Therefore, the rocking rod 7d also moves forward in the boss 8 in conjunction with the movement of the U-shaped solier upper portion 7e.

In this way, the depth of the soiler can be changed by sliding the rocking rod 7d back and forth without bothering changing the connecting portion between the rocking rod 7d and the suspension plate 7b. Even if the rocking rod 7d is not slidable, the suspension plate 7b moves, so that the U-shaped soiler 7 moves back and forth, but the rocking width and movement of the rocking rod 7d are limited. However, by mounting the swing rod 7d in the boss 8 so as to be slidable, it is possible to reduce machine vibration and noise generated during swinging, so that the stability of the working posture is ensured and the work is performed. Noise can be reduced.
Then, as shown in FIGS. 2 and 8, the rocking rod 7 d of the U-shaped soiler 7 is provided on the opposite side to the cylinder 21 for operating the U-shaped soiler 7 in the front-rear direction. The balance is good and the configuration is simple.

Further, as shown in FIG. 3, the blade 7a of the U-shaped soiler 7 can be divided in the left-right direction, and the left and right of the blade 7a of the U-shaped soiler 7 can be adjusted by adjusting the connection location of the left and right blades 7aL, 7aR. The width W may be adjustable.
By making the left and right width W of the blade 7a of the U-shaped soiler 7 adjustable, the left and right width W of the blade 7a can be adjusted to the left and right width of the ridge A, so that the blade 7a may damage the crop a. Prevents crop quality. Then, since the heel A is reliably unwound by the blade 7a, the worker can recover the crop a from the heel A with a light effort, so that the labor of the worker is reduced and the work efficiency is improved. .

  As shown in a round frame portion Y in FIG. 3, for example, the tip of one of the left and right blades 7aL, 7aR (right blade 7aR in the illustrated example) is divided into two and the other ( In the illustrated example, the left blade 7aL) is inserted, and the left and right blades 7aL and 7aR are fixed by the pins 31. Then, one or a plurality of holes (not shown) are formed in the right blade 7aR, and a plurality of holes (not shown) are formed at equal intervals at the tip of the left blade 7aL. The holes of the right blade 7aR and the left blade The horizontal width W of the blade 7a can be changed by adjusting at any position of the plurality of 7aL holes and adjusting the fixing position of the pin 31. If the position of the pin 31 or the like is shifted to either one (either left or right) from the central portion in the left-right direction of the blade 7a, there is no interference with the crops. Therefore, it is possible to prevent the crop 31 from being caught on the pin 31 and being unable to be recovered well or being damaged.

Further, without separating the tips of the blades 7aL and 7aR, the left and right blades 7aL and 7aR are overlapped, and the connection portions of the overlapping blades 7aL and 7aR are supported by the support member 33 and the like. The member 33 can also be fixed by stopping the top and bottom of the member 33 with pins 31 or the like. The left-right width W of the blade 7a can be changed by changing the length in the left-right direction of the overlapping portion of the left and right blades 7aL, 7aR.
By adopting this configuration, the left and right width W of the blade 7a of the U-shaped soiler 7 can be changed simultaneously with the adjustment of the width of the chain cases 2a and 2a.

  Further, the crop harvesting auxiliary machine 1 according to the present embodiment has a main body 4 extended to an extension frame 4a as a foliage discharge device that sends out foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 to the left and right sides of the machine body. A feeding device 35 is provided. The foliage horizontal feed device 35 is disposed above the cutting device 13 in front of the U-shaped soyer 7, and the foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 is guided by the cross feed device 35 to the ridge groove. Discharged. Moreover, since the foliage can be collected in the groin by providing the lateral feed device 35, the foliage can be easily collected.

  As shown in FIG.1 and FIG.2, the foliage horizontal feed apparatus 35 which has a longitudinal direction in the left-right direction is attached between the left and right extension frames 4a and 4a. A drive pulley 37a and a driven pulley 37b are attached to a drive shaft 39a and a driven shaft 39b as support shafts protruding above the left and right extension frames 4a and 4a, respectively, and a protrusion (lug) is formed between the drive pulley 37a and the driven pulley 37b. An endless rotating body with 41a, for example, a lateral feed belt 41 (or a chain) is wound, and a cover 43 is provided on the upper surface of the lateral feed belt 41 to constitute the foliage lateral feed device 35.

The drive shaft 36a of the drive motor 36 is inserted into the drive pulley 37a of the lateral feed device 35 to rotate the drive pulley 37a, and the driven belt 37 is rotated by the rotation of the drive pulley 37a. The pulley 37b and the driven shaft 39b are configured to rotate.
Then, the foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 is guided by the lateral feed belt 41 of the lateral feed device 35 and discharged to the left and right sides of the machine body.

By adopting this configuration, the cut foliage can be discharged into the left and right ridges of the fuselage, and the cut foliage are wound around the foliage cutting device 12, the left and right drive wheels (front wheels) 2, 2 and the like. Therefore, the labor required for the maintenance of the crop harvesting auxiliary machine 1 is reduced.
Further, since the foliage is collected in the groin, it can be easily collected when collecting the foliage, and when the foliage is buried in the field, it can be easily buried just by breaking the ridge A.

Then, by providing the foliage laterally feeding device 35 above the extension frame 4a and the main frame 4 in this way, the cut foliage lying on the extension frame 4a and the main frame 4 is laterally (one side on the left and right sides). ) Easy to discharge.
Moreover, the cutter support part 17 and the support arm 14 of the reciprocating cutter 13 are connected so as to be L-shaped in a side view so as not to interfere with the foliage lateral feed device 35. And since the foliage horizontal feed device 35 is located in the L-shaped space part which the cutter support part 17 and the support arm 14 comprise, the whole structure becomes compact.

In FIG. 4, the front enlarged view of the crop harvesting auxiliary machine of FIG. 2 is shown.
The reciprocating cutter 13 is arranged in a direction orthogonal to the crop planting rod A, but the foliage feed device 35 is obliquely seen in plan view so as to have an angle θ with respect to the direction orthogonal to the crop planting rod A. Shift and arrange. That is, the left and right end portions of the foliage lateral feeding device 35 are provided so that the positions in the front-rear direction are different. For example, as shown in FIGS. 2 and 4, in the direction orthogonal to the crop planting rod A, the drive pulley 37a at the left end of the foliage lateral feed device 35 is forward and the driven pulley 37b at the right end is rearward. On the other hand, the lateral feed device 35 is arranged with an angle θ shifted. You may arrange | position so that the driven pulley 37b may become the front and the drive pulley 37a may become the back.

The lateral feed belt 41 of the foliage lateral feed device 35 rotates in the direction of arrow D, but the left and right one end portions on the foliage discharge side (right driven pulley 37b side in the illustrated example) are connected to the other end side (in the illustrated example). It is better to arrange it behind the left driving pulley 37a side).
Thus, by arranging the foliage laterally feeding device 35 obliquely with respect to the direction orthogonal to the crop planting rod A, the front and back positions at which the laterally feeding belt 41 acts on the foliage cut by the reciprocating cutter 13 can be obtained. It will be different on the left and right.

  For example, when the transverse feed device 35 is arranged without an angle in the direction orthogonal to the crop planting rod A, the foliage cut by the reciprocating cutter 13 is gathered together on the transverse feed belt 41 of the transverse feed device 35 and the aircraft is There are cases where it becomes a hindrance when moving forward and gets stuck between the reciprocating cutter 13 and the lateral feed belt 41.

  However, by adopting this configuration, the foliage cut by the reciprocating cutter 13 is smoothly fed from the front left and right end portions to the rear left and right end portions. In addition, since the reciprocating cutter 13 and the foliage feeding device 35 are not provided in parallel in the longitudinal direction in this way, the reciprocating cutter 13 and the feeding device 35 do not interfere with each other, so that the foliage cut by the reciprocating cutter 13 can be smoothly left and right. Can be laterally fed to one discharge side, improving work efficiency.

  Then, assuming that the speed of the foliage horizontal feed device 35 is V2, and the work speed of the crop harvesting auxiliary machine 1 (the speed of moving forward while solving the soil around the crop) is V1, the relation of V1 <V2 is established. That is, the speed V2 of the lateral feed device 35 is set higher than the work speed V1 of the crop harvesting auxiliary machine. Basically, it is sufficient that the rotational speed V2 of the lateral feed belt 41 of the lateral feed device 35 always exceeds the work speed V1 of the machine body by the engine output, and the operator can rotate the engine output and the motor 36 of the lateral feed device 35. Can be adjusted by setting.

  When the speed V2 of the foliage feed device 35 is slower than the work speed V1 of the crop harvesting auxiliary machine 1, the foliage cut by the reciprocating cutter 13 accumulates on the cross feed belt 41 of the cross feed device 35, and assists crop harvesting. This may hinder the aircraft from traveling. However, by adopting this configuration, since the foliage cut by the reciprocating cutter 13 can be quickly discharged, it is possible to prevent the crop harvesting auxiliary machine 1 from being hindered and the work efficiency is improved.

Also, the worker works while standing on the side where the depth adjustment switch 15 of the machine body is located, so that the end of the foliage discharge side of the lateral feeding device 35 is located on the opposite side to the position where the worker stands. When the lateral feed device 35 is provided, the foliage can be discharged to a position opposite to the position where the worker stands, so that the worker's passage is not obstructed.
For example, as shown in FIG. 2, the position N where the operator stands is on the left side, whereas a driven pulley 37b on the foliage discharge side is provided on the right side, and is retracted compared to the left driving pulley 37a.

By adopting this configuration, the foliage is discharged to the opposite side of the worker's path, and the foliage is not discharged to the worker's path, so the discharged foliage interferes with the worker's traffic. The work efficiency is improved.
Then, when the working width (left-right width) S of the foliage lateral feed device 35 is made wider than the left-right width L of the reciprocating cutter 13, the foliage cut by the reciprocating cutter 13 is reliably transferred to the lateral feeding belt 41 of the lateral feeding device 35. Since it receives an action, it is reliably discharged without remaining in the field.

  A left side view of a crop harvesting auxiliary machine 1 according to another embodiment of the present invention is shown in FIGS. 5 and 6, and a plan view is shown in FIG. The crop harvesting auxiliary machine 1 shown in FIG. 5 is an example in which the lateral feed device 35 is provided below the extension frame 4a and the main frame 4. The crop harvesting auxiliary machine shown in FIG. This is an example provided on both the upper and lower sides of the main frame 4. In the present embodiment, as shown in FIG. 7, the arm 14 of the reciprocating cutter 13 is arranged on the outer side of the machine body relative to the foliage horizontal feeding device 35 so that the reciprocating cutter 13 and the foliage horizontal feeding device 35 do not interfere with each other.

  As shown in FIG. 5, if the lateral feed device 35 is provided below the extension frame 4 a and the main frame 4, the foliage accumulated under the extension frame 4 a and the main frame 4 can be easily discharged sideways.

For example, in the case of a cultivar having a short shoot and a short cultivar or a cultivar having a narrow stalk and foliage, the transverse feed device 35 may be provided below. When the vertical length of the foliage is short, if the distance between the horizontal feeding device 35 and the field scene is large, the foliage that is cut and falls may not contact the working surface of the horizontal feeding device 35, and if the foliage is thin, the horizontal direction When it falls down, it can be considered that it enters the space between the lateral feed device 35 and the farm scene and is not laterally fed.
In addition, even when the foliage is withering or the like, it is easy to discharge by providing the lateral feed device 35 on the lower side. Further, under conditions other than crops, when the wind is strong and the cut foliage falls down quickly, the foliage can be easily fed laterally by providing the cross feed device 35 on the lower side.

  In addition, as shown in FIG. 6, by providing a plurality of transverse feeding devices 35 (upper lateral feeding device 35U, lower lateral feeding device 35L) in the vertical direction, the foliage cut by the reciprocating cutter 13 is surely discharged. become able to. The drive shaft 40a of the drive motor 40 is inserted into the upper drive pulley 37aU and the lower drive pulley 37aL of the upper lateral feed device 35U and the lower lateral feed device 35L, and the vertical drive pulleys 37aU and 37aL are rotated. By rotating the vertical drive pulleys 37aU and 37aL, the vertical lateral feed belts 41U and 41L rotate, whereby the vertical driven pulleys 37bU and 37bL and the driven shaft 39b rotate.

  For example, the configuration is simple by installing the lateral feed devices 35U and 35L so as to be sandwiched between the extension frame 4a and the main frame 4. And by installing the cover 45 between the horizontal feeding devices 35U and 35L provided above and below, the leaf stems are not clogged between the horizontal feeding devices 35U and 35L or between the horizontal feeding devices 35U and 35L and the extension frame 4a.

A second drive source different from the drive engine 5 for the front wheels 2 and 2 is used as a drive source for the reciprocating cutter 13 of the foliage cutting device 12 of the crop harvesting auxiliary machine 1 shown in FIGS. (Second engine 47) is provided. The engine may be changed to a motor.
In FIG. 8, the top view of the crop harvesting auxiliary machine 1 which does not illustrate the cross feed apparatus 35 of FIG. 2 is shown.

  By providing the second engine 47 for driving the reciprocating cutter 13 of the foliage cutting device 12, even if the traveling speed of the crop harvesting auxiliary machine 1 is changed, the driving of the reciprocating cutter 13 of the foliage cutting device 12 is not affected. Can be harvested. The reciprocating cutter 13 swings in the left-right direction (the direction of arrow E in FIG. 8) by the power of the second engine 47.

And if the counterweight 50 is provided as a balancing member on the opposite side of the second engine 47, the balance between the left and right sides of the airframe is stabilized. The counterweight 50 is attached to the outside of the side wall of the cutter support portion 17 that sandwiches the blade of the reciprocating cutter 13. The attachment method may be welding, fixing with a fixing member such as a bolt, or integral formation with the side wall of the reciprocating cutter 13.
The second engine 47 is provided on the side opposite to the position N where the operator stands (left side in the illustrated example).

By adopting this configuration, the cutting force of the reciprocating cutter 13 of the foliage cutting device 12 does not change even if the traveling speed of the crop harvesting auxiliary machine 1 or the swinging pace of the U-shaped soyer 7 is changed. It is prevented that the foliage is not cut due to lack.
Further, by providing the counterweight 50 on the opposite side of the foliage cutting device 12 from the second engine 47 for driving the reciprocating cutter 13, the balance in the left-right direction of the machine body is stabilized.

  Further, by arranging the adjustment lever 14a for adjusting the height of the reciprocating cutter 13 in the vicinity of other levers (the handle 6 and the depth adjustment switch 15 of the soiler 7 etc.), the worker can Various operations can be performed continuously without moving.

FIG. 9 shows an example in which the lateral feed belt 41 of the lateral feed device 35 of the crop harvesting auxiliary machine 1 of FIGS. 1 to 6 is changed, and the front portion of the lateral feed device 35 (the portion acting with the foliage) is shown. A front view (simplified view) is shown. An enlarged view of the brush portion 53 is shown in a round frame portion Z of FIG.
The lateral feed device 35 may be an endless rotating body 42 with a brush 53 in which a plurality of brush hairs 53b are bundled and supported by a support portion 53a, instead of the lateral feed belt 41 with a lug as shown in FIGS. . As the endless rotating body 42, a belt or a chain may be used. By constructing the lateral feed device 35 from a belt (or chain) with a brush 53, the foliage can be reliably discharged without damaging the crop and removing soil adhering to the crop. Furthermore, if the tip of the bristle 53b of the brush 53 is rounded (for example, shown in a round frame portion Q in FIG. 14), the crop is not further damaged.

  For example, when the lateral feed device 35 is driven by the chain 42 and the support portion 53a of the brush 53 can be attached to and detached from the link of each chain 42 by pinning or the like, the brush 53 can be easily replaced. Moreover, as shown in the round frame portion Z, the shape of the bristle 53b of the brush 53 is a square shape spreading from the support part (base side) 53a toward the tip, so that the lower side of the bristle 53b of the brush 53 Are overlapped with each other between the adjacent left and right brushes 53, and this is preferable because it acts on the crop with certainty.

FIG. 10 is a left side view of the crop harvesting auxiliary machine 1 of FIG. 1 in which the foliage cutting device 12 and the transverse feed device 35 are not shown, and the U-shaped soiler 7 is installed in the chain cases 2a and 2a. . FIG. 11 shows a front view of the vicinity of the soiler 7 of the crop harvesting auxiliary machine 1 of FIG.
As shown in FIGS. 10 and 11, by installing the U-shaped soiler 7 in the chain cases 2a and 2a, the suspension plates 7b and 7b for supporting the blade 7a of the U-shaped soiler 7 are unnecessary or short. can do. Further, since the soil is unraveled in the vicinity of the front wheels 2 and 2 by the blade 7a, the work can be performed without a driving force, and the configuration is compact and economical. As shown in FIG. 11, the suspension plates 7b and 7b can be easily installed by being connected to support pieces 11 and 11 fixed to the lower portions of the chain cases 2a and 2a by pins 31 and 31, respectively.
If the U-shaped soiler 7 is installed outside (indicated by M) from the inner surfaces of the chain cases 2a and 2a, the crops I and the U-shaped soiler 7 will not interfere with each other, such as ginger or gold dust Can also be used. Since these crops have an edible part in the ridge A, it is necessary for the U-shaped soira 7 to pass below the crops I and unravel the soil around the crops I. Therefore, when the U-shaped soiler 7 is provided outside the inner side surfaces of the chain cases 2a, 2a as in the above configuration, the U-shaped soiler 7 enters the lower part of the heel A from both outer sides of the heel A. Therefore, even if the crop i grows to near the bottom of the ridge A, the U-shaped soira 7 can pass under the crop a.

FIG. 12 shows a side view when the arrangement of the lateral feed device 35 of the crop harvesting auxiliary machine 1 of FIG. 2 is changed and a further entraining device 60 is provided, and FIG. 13 shows the crop harvesting auxiliary machine 1 of FIG. The top view of is shown.
As shown in FIGS. 12 and 13, a lateral feed device 35 is provided between the front wheels 2, 2 and the rear wheels 3, 3, and the lateral feed device 35 is provided between the front wheels 2, 2 and the rear wheels 3, 3. You may make it remove the cut foliage which accumulates in this space part. Moreover, you may provide the winding apparatus 60 which rolls in the foliage cut | disconnected by the reciprocating cutter 13 of the foliage cutting apparatus 12, and guides it to the back lateral feed apparatus 35. FIG.

  And the front-end | tip part of the foliage part of crop i can be rolled in before the reciprocating cutter 13 acts on crop i by installing the action part 60a of the winding apparatus 60 in front of the foliage cutting apparatus 12. FIG. With the entraining device 60, the stem and leaf portions of the crop i are entrained and guided downward, and the one that has fallen on the ridge A is moved to the ridge groove by the lateral feed device 35.

  When the action part 60a of the entraining device 60 is installed behind the foliage cutting device 12, the reciprocating cutter 13 acts on the crop a before the entraining device 60, and the foliage portion of the crop i is cut and falls to the field. The foliage can not be rolled up by the winding device 60 and sent to the lateral feed device 35 at the rear. However, by installing the action part 60a of the entraining device 60 in front of the foliage cutting device 12, the foliage can be entrained and supported before cutting, so that the foliage can be reliably sent to the rear lateral feed device 35. Further, since the foliage of the crops i is supported by the entrainment device 60 at the time of cutting, the foliage is surely cut by the reciprocating cutter 13.

  As shown in FIG. 12, the entrainment device 60 includes a rotating body 61 with blades 62 that rotate in the direction of arrow G, and a rotating body cover portion 63 that covers the upper portion of the rotating body 61. 61 is sandwiched between action parts 60a between the rotating body cover part 63 and the rotating body 61, and is discharged backward by the movement of the rotating body 61 in the direction of the arrow G and falls in the direction of the arrow H. To 35.

  The rotating body cover portion 63 is supported by cover mounting columns 63a provided on the left and right main frames 4, 4. The rotating shaft 61 a of the rotating body 61 with the blades 62 is connected to the left and right side walls of the rotating body cover portion 63. And the rotational driving force of the winding device 60 is transmitted from the drive motor 64 attached to the rotating shaft 61a.

  Thus, by using the entraining device 60 together with the foliage cutting device 12, the foliage portion of the crop a can be reliably cut from the root. That is, by simultaneously driving the reciprocating cutter 13 of the foliage cutting device 12 and rotating the rotating body 61 of the entraining device 60, the foliage cut by the reciprocating cutter 13 is quickly entrained in the entraining device 60 and smoothly fed laterally. The work efficiency is improved by being sent to the apparatus 35 and discharged.

  In addition, by providing the lateral feeding device 35 on the lower rear side of the entraining device 60, the entrained foliage can be surely fed rearward and guided to the lateral feeding device 35, so that the ridge A is a multi-film. Even when it is cultivated with covering with, the foliage can be removed from the multifilm.

  And the right-and-left width of the entraining device 60 may be made substantially the same as the left-right width of the reciprocating cutter 13 of the foliage cutting device 12. Since the left and right widths of the foliage cutting device 12 and the entraining device 60 are the same, the cut foliage can be efficiently entrained by the entraining device 60, so that the number of foliage falling to the field without being involved is reduced, and the wheels of the aircraft It is possible to prevent the foliage from getting entangled with 2, 3 and the operator.

  Further, it is preferable to provide protrusions 41b and 41c on the top and bottom of the lateral feed belt 41 of the lateral feed device 35, respectively. The foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 is caught on the protrusions 41b and 41c of the horizontal feed belt 41 of the horizontal feed device 35, so that the foliage can be reliably sent to the left and right sides without being scattered in the field. .

  Further, by making the protrusion length U of the protrusions 41b and 41c longer than the length U2 of the lower protrusion 41c than the length U1 of the upper protrusion 41b, the foliage contacts the lateral feed belt 41 of the lateral feed device 35. Even if it falls down before it falls, since the foliage 41c in the lower part can be reliably caught and fed laterally, the foliage can be reliably guided to the groin, and the discharge power of the foliage is improved.

  The position where the operator stands is provided by providing the lateral feed device 35 so that the end (on the driven pulley 37b side) of the foliage discharge side of the lateral feed device 35 is located on the opposite side to the position N where the worker stands. Since the cut foliage can be discharged to the opposite side of the position, it does not obstruct the operator's traffic.

FIG. 14 shows a side view when the lateral feed device 35 of the crop harvesting auxiliary machine 1 of FIG. 12 is changed, and FIG. 15 shows a plan view of the crop harvesting auxiliary machine 1 of FIG.
The lateral feed device 35 is not configured in such a manner that the endless belt 41 (chain) is wound between the driving pulley 37a and the driven pulley 37b shown in FIGS. 1 and 2, but as shown in FIGS. It is good also as the rotary body 55 with a brush which bundled the bristles 55b and was supported by the support part (base part) 55a. And it is good to provide this brushed rotary body 55 under the main frame 4, and to install in a pair on the left and right.

  A drive motor 56 is attached to one of the left and right rotating shafts 55L and 55R with a brush, a drive sprocket (pulley) 57a is attached to the rotary shaft to which the drive motor 56 is attached, and a sprocket is driven by the opposite rotary shaft. A (pulley) 57b is attached to the shaft, and a transmission chain (belt) 59 is wound endlessly around the drive sprocket (pulley) 57a and the driven sprocket (pulley) 57b.

The right brushed rotating body 55R rotates in the direction of the arrow P1, and the left brushed rotating body 55L rotates in the direction of the arrow P2, so that the left and right brushed rotating bodies 55L and 55R rotate from the inside to the outside and forward. From the back to the back, the foliage can be discharged to the left and right sides.
And as shown to the round frame part Q of FIG. 14, if the front-end | tip of the bristle 55b of the rotary bodies 55L and 55R with a brush is rounded, when covering and growing the cocoon A with a multifilm, it will become a multifilm. The multi-film is not broken even if touched.

Further, by making the length F2 of the brush bristles 55b and 55b of the rotating bodies 55L and 55R with brushes longer than the vertical length F1 of the support portions (base portions) 55a and 55a, the foliage is supported by the support portions 55a and 55a. Since it is carried out by the brush hairs 55b and 55b without being entangled with both sides of the machine body, the discharge of the foliage is improved.
The brush bristles 55b and 55b of the rotating bodies 55L and 55R with brushes are shaped like a letter C opened downward in a side view, so that the foliage can be removed even if the foliage dropped from the entraining device 60 is scattered widely in the field. Since it can be brought into contact with the brush bristles 55b and 55b of the rotary bodies 55L and 55R with brushes and carried out to both outer sides of the machine body, the discharge of the foliage is improved.

Moreover, the discharge property of a foliage improves by decentering the rotary bodies 55L and 55R with a brush. A method in which the support portions 55a and 55a of the rotating bodies 55L and 55R with brushes are formed in an elliptical shape and the shaft is shifted from the center position, or the shaft is shifted from the center of the circular support portions 55a and 55a. If it is attached, it becomes eccentric.
Further, at the front center between the left and right rotating bodies 55L and 55R with brushes, the foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 is prevented from entering between the left and right rotating bodies 55L and 55R with brushes. A guide plate 66 may be provided for the purpose. The guide plate 66 is connected to the main frame 4.

  The guide plate 66 is a plate having a flat portion in a direction orthogonal to the traveling direction of the crop harvesting auxiliary machine 1, and has a square shape with a front end portion protruding in a plan view. The cut foliage hits the flat portion of the guide plate 66, and is guided to the left and right rotating bodies 55L and 55R with brushes along the shape of the guide plate 66 from the front end portion to the rear end portion of the dogleg shape. .

Since there is a space between the left and right rotating bodies 55L and 55R with the brush, the cut leaves are easily collected in the space.
However, by providing the guide plate 66 in this way, the foliage enters between the left and right rotating bodies 55L, 55R with the brush and does not escape. By providing the guide plate 66, the foliage discharged between the left and right rotating bodies 55L, 55R with the right and left brushes are not collected there, but are guided in the left and right directions along the shape of the guide plate 66 in the directions of the arrows J1 and J2. Thus, the left and right brush-equipped rotating bodies 55L and 55R are efficiently discharged into the groove.

  In this way, the foliage divided by the guide plate 66 is sent to the left and right sides of the machine by the rotary bodies 55L and 55R with brushes and discharged to the gutter groove. However, if there is no guide plate 66, the foliage is a rotary body with brushes. It may move backward through the space between 55L and 55R. Therefore, the foliage can be prevented from moving backward.

Further, positioning guides 65 and 65 (not shown in FIG. 14) are respectively provided on the left and right sides so that the foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 is not blown out of the left and right rotating bodies 55L and 55R with brushes. )), The foliage can be reliably dropped into the ridge.
The positioning guides 65, 65 are preferably formed of a plate body having a plane portion substantially parallel to the traveling direction of the crop harvesting auxiliary machine 1 in a side view, and have substantially the same height as the left and right rotating bodies 55L, 55R with brushes.

And the positioning guides 65 and 65 can be easily attached by installing in the rear part of the extension frames 4a and 4a.
Further, the positioning guides 65, 65 are arranged obliquely with respect to the traveling direction of the crop harvesting auxiliary machine 1 so that the positioning guides 65, 65 are along the outer periphery of the left and right rotating bodies 55L, 55R in plan view, or the left and right rotating bodies 55L with brushes. , 55R (L shape, arc shape, etc.), the stems and leaves are discharged to the same place along the trajectory of the brushed rotating bodies 55L, 55R without scattering.

  By adopting this configuration, the foliage cut by the reciprocating cutter 13 of the foliage cutting device 12 hits the positioning guides 65 on the left and right outer sides of the left and right rotating bodies 55L and 55R without being flicked off in all directions.
