An operation lever 11 is provided.

  Then, left and right pulling drive shafts 12 and 12 are provided in a downwardly inclined posture toward the front upper side from the branch transmission case 6, and left and right pulling drive pulleys 13 and 13 are provided at upper ends of the left and right pulling drive shafts 12 and 12. And a leaf drive pulley 14 is mounted below the pull-out drive pulley 13 on the left and right sides. Further, left and right pulling frames 15 and 15 having long sides in the front-rear direction are provided at the lower portions of the left and right pulling drive pulleys 13 and 13 respectively in a tilted rearward posture, and left and right at the front end portions of the left and right pulling frames 15 and 15. The pulling driven pulleys 16 and 16 are rotatably provided. Further, a plurality of left and right pulling driven pulleys 16, 16 and a left and right pulling driving pulleys 13, 13 are rotatably provided between the left and right pulling driven pulleys 13, 13. The left and right pulling drive pulleys 13 and 13 and the left and right tension rollers 17, 17... Then, the left and right pulling covers 19, 19 are provided above the left and right pulling frames 15, 15 in a parallel posture with the left and right pulling frames 15, 15, that is, in a back-up tilting posture in which the tilt angle is substantially the same. A transport device 20 is configured.

  Further, a base portion side of the leaflet frame 21 is provided below the leaflet drive pulley 14, the end portion side of the leaflet frame 21 protrudes toward the left and right sides of the rear side, and the end of the leaflet frame 21 is A leaf leaf driven pulley 22 is rotatably provided on the part side. The leaf drive belt 14 provided with a plurality of leaf lugs 23 a... For hooking the leaf leaves to the leaf drive pulley 14 and the leaf driven pulley 22 is wound, and a leaf cover is disposed above the leaf frame 21. The leaflet conveying device 25 is configured by arranging 24 in a parallel posture, that is, by projecting the end portion toward the left and right sides of the rear side.

  With the above-described configuration, when the foliage portion of the onion cut by the cutting rotary blade 49 and the cutting fixed blade, which will be described later, moves to the terminal end portion of the pulling and conveying device 20, the foliage portion is collected and conveyed by the drainage lugs 23a. Since it is discharged out of the machine or onto the right drive wheel 84R, which will be described later, from the conveyance terminal part of the leaf delivery apparatus 25 protruding to the left and right sides of the machine body, the leaves and leaves are prevented from remaining on the machine body and cut. The removal operation of the foliage part becomes easy and the maintainability improves.

  Further, as shown in FIGS. 1 to 3 and FIGS. 6 to 8, a support plate 99 that is long in the vertical direction is provided on one of the left and right sides of the rear side of the body frame 1, and the branch transmission is provided above the support plate 99. The left and right one side ends of the output shaft 6a extending from the case 6 to the left and right sides are penetrated. Further, a base portion of a rotating rod 100 for rotating the rocking sour 29 in the front-rear direction in a plan view is provided on the left and right sides of the support plate 99, that is, on the outer side of the machine body, and on the other side of the support plate 99, that is, the machine body. A base portion of a rocking rod 101 for rocking the rocking solitary 29 in the longitudinal direction of the machine body is provided inside.

The rocking rod 101 is also provided on the left and right other sides of the machine body, and the rocking solitary 29 on the left and right other sides is similarly rocked.
The left and right rocking soilers 29, 29 reciprocate in the vicinity of the lower side of the onion when unraveling the soil around the onion. As a result, the beard-like root portion (beard root) that grows in the lower part of the onion comes into contact with the left and right rocking soilers 29 and 29 and is shredded to some extent. However, the action of removing the root of the whiskers by the left and right rocking soilers 29 and 29 is secondary, and the amount of the hair root remaining on the onion is not stable. In particular, there is a gap at the inner ends of the left and right rocking soilers 29, 29, and the vicinity of this gap is likely to remain uncut.

For this reason, it is necessary for the worker to remove the hair root from the harvested onion manually or using a dedicated machine, and there is a problem that the worker spends extra labor.
In order to solve the above problem, as shown in FIGS. 4 and 6 to 8, a root cutting bar that cuts in contact with the hair root at the inner side and the rear end portion of the left and right rocking soilers 29 and 29. 29s are provided. The root cutting bars 29 s and 29 s are projected toward the left and right spacing portions between the left and right swinging soilers 29 and 29, and the left and right root cutting bars 29 s and 29 s intersect at the left and right spacing portions.

  If the root cutting bars 29s, 29s are made of a material having elasticity such as rubber, which can be easily deformed when a load is applied, the root cutting bars 29s, 29s are bent when overloaded or contacted with an onion. Damage to the onion is prevented.

  With the above configuration, since the beard roots of the onion located at the left and right spacing portions of the left and right rocking soilers 29 and 29 are cut in contact with the left and right root cutting bars 29s and 29s, the roots are removed from the harvested onion. This eliminates the need for work, improving work efficiency and reducing the labor of the worker.

  Further, by providing the left and right root cutting bars 29s and 29s at the rear ends of the left and right rocking soilers 29 and 29, even if the left and right root cutting bars 29s and 29s are crossed, a difference in height is unlikely to occur. The root cutting position is not disturbed.

The left and right root cutting bars 29s and 29s may be made of metal or a resin having low elasticity, and the outer periphery may be covered with a soft material cover such as vinyl chloride or urethane.
As shown in FIGS. 6 to 8, the rotating rod 100 includes a rotating eccentric cam 100a into which the output shaft 6a is inserted, and a rotating shaft portion 100b in the front-rear direction attached to the rotating eccentric cam 100a. A pillow ball 100c is provided at the front end of the pivot shaft 100b. The swing rod 101 is configured by providing a swing shaft portion 101b between a swing eccentric cam 101a into which the output shaft 6a is inserted and a mounting boss 101c on the front side of the machine body.

  Then, the pillow ball 100 c provided at the front end of the rotating rod 100 is provided on the rotating plate 103 provided on the upper part of the vertical rotating arm 102. The rotating plate 103 is detachably attached to the upper end of the sour rotating arm 102, and when mounted, the rotating plate 103 rotates in conjunction with the rotating rotating plate 103. In addition, a rotation connection pin 103a is provided on one side of the rotation plate 103 on the left and right sides (outside the machine body), and the rotation connection pin 103a is inserted and connected to the pillow ball 100c.

  Thereby, when the rotating rod 100 is rotated by the output shaft 6a, the rotating plate 100 reciprocates in the front-rear direction by the eccentric rotation of the swing eccentric cam 100a, and is connected to the pillow ball 100c by the front-rear reciprocating movement. 103 is reciprocatingly rotated in the front-rear direction in a plan view, and is configured to reciprocally rotate in the front-rear direction in conjunction with the solitary rotation arm 102 provided at the lower portion of the rotation plate 103.

  Further, a bifurcated solitary support arm 105 is provided in the vertical direction below the sour rotating arm 102, and the upper side of the swinging soli 29 is inserted into the bifurcated portion of the sora support arm 105. And connecting holes (not shown) respectively formed in the swinging sour 29, and fixing members 29a such as bolts and nuts are inserted into the connecting holes to fix the swinging sour 29. The swinging soiler 29 is configured such that the lower side is bent toward the pulling and conveying area R and formed into an L shape (reverse L shape) when viewed from the front, and enters the soil from the side of the ridge.

  A plurality of the connection holes are formed in the vertical direction on either or both of the support arm 105 and the swing soiler 29, and the working height of the swing soiler 29 is changed by changing the combined connection hole. If possible, it can be set to an appropriate height that meets conditions such as the vertical length of the crop to be harvested, the depth of burial in the soil, or the presence or absence of multi-film, and the soil to be harvested is not damaged. Therefore, the quality of the crop is maintained and the work efficiency is improved.

  In addition, a protective cover (not shown) is provided at least at the connecting portion between the pillow ball 100c and the rotating connecting pin 103a to stop the rotating operation by biting a foliage portion or sand into the connecting portion, or the biting sand, etc. This prevents the pillow ball 100c and the rotation connecting pin 103a from being worn away.

  A hollow solitary swinging case 107 is provided on the outer periphery of the sour rotating arm 102 and between the rotating plate 103 and the upper and lower support arms 105. A swing connecting pin 106 for inserting the mounting boss 101c of the swing rod 101 is provided on the upper end side of the inner side of the body of the rocker swing case 107.

  Even when the solitary rocking case 107 is moved in the front-rear direction by the rocking rod 101, the solitary rotating arm 102 is interlocked with the rotation of the rotating plate 103 by the rotating rod 100. It is set as the structure which can reciprocately rotate to a direction.

  Thus, when the swinging rod 101 is rotated by the output shaft 6a, the swinging eccentric cam 101a is reciprocated in the front-rear direction by the eccentric rotation of the swinging eccentric cam 101a, thereby reciprocatingly swinging the solitary rotating arm 102 in the front-rear direction. .

  With the above configuration, when the output shaft 6a rotates, the rotating rod 100 is reciprocated in the front-rear direction, and along with this reciprocating movement, the soli-rotating arm 102 reciprocally rotates in the front-rear direction in plan view. Since the swinging sour 29 provided on the arm 105 can be rotated in the front-rear direction in a plan view, the soil can be dug reliably from the base side to the end side of the swinging sour 29. The soil is prevented from resisting when the onion is pulled out, and the work efficiency is improved.

  In particular, since the soil around the onion planted at a position away from the mounting base of the swinging soiler 29 in the body inner direction, that is, the onion planted near the center in the left-right direction of the kite, can be easily unwound. The efficiency is improved, the onion is prevented from being left unchecked, and the time and labor for the operator to manually harvest the onion are reduced.

  In addition, since the swinging sour 29 rotates about the left and right side of the swinging arm 102 as a fulcrum, the amount of rotation increases toward the other left and right sides of the swinging soy 29, so that the width before and after unraveling the soil becomes wider. The soil is dug more reliably and the efficiency of the onion pulling and harvesting work is improved.

  Further, when the output shaft 6a rotates, the rocking rod 101 is reciprocated in the front-rear direction, so that the rocking soiler 29 can be swung in the front-rear direction. As a result, the onion is prevented from being pulled out and damaged, and the operator does not need to dig up the onion, thereby reducing the labor of the operator.

  Furthermore, the rocking rod 101 is swung in the front-rear direction by the rocking rod 101 and the rocking sour 29 is swung in the front-rear direction by the rotating rod 100, so that Since the soil can be unraveled reliably, it is possible to harvest multiple onions without losing pulling out, improving work efficiency and eliminating the need for the operator to manually harvest the remaining onions, Save time and effort.

  The swinging soiler 29 enters the cage as the aircraft moves forward, and unravels the dredged soil from the soil. In order to prevent it from coming into contact with the onions planted in the soil, Pass through. When the rocking soy 29 passes under the onion, the rocking soy 29 can be brought into contact with a thin hair root extending from the lower part of the onion into the soil and the root can be cut when the soil is unwound. Therefore, the labor of removing the hair root from the onion after harvesting is reduced.

  However, in the conventional configuration, when the soil is difficult to unravel due to soil quality, onion growth state, etc., the rocking soiler 29 is located around the onion that is vegetated near the center of the straw away from the mounting base of the rocking soiler 29. Since it does not swing back and forth almost back and forth, the soil is difficult to unravel and the onion is not pulled out, and the roots are not cut, and many remaining roots after harvesting must be removed, which is necessary for the removal work There is a problem that time and labor increase.

  The onion root of the onion has innumerable thin roots at the center of the lower bulb, but it grows at a position close to the edible part with commercial value, so it can be removed without damaging the edible part. Since a precise cutting is necessary, the time and labor required for the removal work tend to increase as the remaining amount increases.

  In the configuration of the present application, the swinging soluer 29 is rotated in the front-rear direction in a plan view by the rotating rod 100, and the end side of the swinging soluer 29 is rotated back and forth more significantly than the base side with the sour rotating arm 102 as a fulcrum. Since it is configured to move, the oscillating soiler 29 can remove the roots of the onion while digging the soil near the center of the reed, thus reducing the labor and time for removing the reeds from the harvested onion. .

  Further, in this configuration, a solitary rocking case 107 is provided on the outer periphery of the solitary rotating arm 102, and even if the rocking rod 101 reciprocates the solitary rocking case 107 in the front-rear direction, the solitary rotating arm 102 does not rotate. Since the structure is configured to rotate in conjunction with the rotation of the moving plate 103, the reciprocating rocking in the front-rear direction and the reciprocating rotation in the front-rear direction of the rocking soiler 29 interfere with each other. It is possible to prevent the efficiency of removing the root of the hair from being lowered.

  The working height of the rocking solubilizer 29 is such that the connecting holes formed in the soli support arm 105 and the rocking solubilizer 29 are combined, and fixing members 29a such as bolts and nuts are inserted into the connecting holes. However, if the vertical position needs to be changed significantly when adjusting to the height of the ridge or the vegetation position of the onion, the above adjustment method may not be able to cope with it.

  In order to solve this problem, in this case, as shown in FIGS. 1 to 3, 6, and 7, the left and right sides on the rear side of the body frame 1 and the left and right sides of the drive wheels 84 </ b> R on the left and right sides. An adjustment support plate 108 is provided on the other side facing downward, and a rear end portion of the vertical adjustment cylinder 109 is rotatably attached to the adjustment support plate 108. A vertical adjustment lever (not shown) for operating expansion / contraction of the vertical movement adjustment cylinder 109 is provided in the vicinity of the travel operation lever 10. A front end portion of the vertical adjustment cylinder 109 is rotatably provided at a lower portion of the relay rotation arm 110, and a rear end portion of the vertical adjustment arm 111 is provided at an upper portion of the relay rotation arm 110. A front end portion of the vertical adjustment arm 111 is connected to the solar swing case 107.

  At this time, the front end of the vertical adjustment arm 111 is located below the vertical center position of the rocker swing case 107 and higher than the soli support arm 105 so as to increase the vertical adjustment amount of the rocking soiler 29. It shall be provided above. Further, the front end of the vertical adjustment arm 111 is constituted by a bifurcated branch support 111a, and a solitary swing case 107 is disposed in a space portion of the branch support 111a. 112 is configured to be able to rotate by making contact with the rocker swinging case 107.

  Accordingly, when the vertical adjustment cylinder 109 is expanded and contracted, the relay rotation arm 110 is rotated in the front-rear direction, and the vertical adjustment arm 111 is moved in the front-rear direction in conjunction with the vertical movement of the sor swing case 107. It becomes composition.

  The vertical adjustment cylinder 109 may be electrically operated or hydraulic. However, if it is replaced with an expansion / contraction rod (not shown) that expands and contracts when the handle is turned, the labor required for the operation increases, but an energizing cable or transmission Oil pipes are no longer required, and costs can be reduced.

  As described above, the operating position of the rocking soiler 29 can be appropriately changed in accordance with the height of the reed and the depth of the soil in which the onion is buried, so that the rocking soiler 29 contacts the onion in the soil. Damage to the product, and the commercial value of the onion is improved.

  Moreover, since the rocking soiler 29 is too far from the onion in the vertical direction, the soil around the onion cannot be unraveled, and the onion can be prevented from remaining on the field without being pulled out, so it is necessary for the operator to harvest the onion manually. The labor of the operator is reduced.

Further, since it is possible to prevent the beard root of the onion from being drawn and harvested without being cut, the time and labor required for the work of removing the root from the onion after harvesting can be measured.
With the above configuration, under the four-row planting work conditions, the soil around the two onions is dissolved to facilitate pull-out harvesting, and the roots are removed to reduce the labor required for post-harvest preparation work. It becomes possible to do.

  The upper ends of the left and right rotation shafts 16a, 16a of the left and right pulling driven pulleys 16, 16 provided at the front end of the pulling and conveying apparatus 20 are protruded upward through the left and right pulling covers 19, 19, Left and right transmission cases 34 and 34 having left and right input pulleys 31 and 31 mounted in the front side of the machine body are provided at the upper ends of the left and right pull-out covers 19 and 19 at the upper end portions of the left and right rotating shafts 16a and 16a. In addition, left and right output pulleys 32 and 32 are rotatably mounted on the rear side of the left and right transmission cases 34 and 34, and the left and right input pulleys 31 and 31 and the left and right output pulleys 32 and 32 have left and right transmissions. Each of the belts 33 and 33 is wound.

  Then, the lower ends of the left and right first universal joints 35 and 35 are mounted on the upper sides of the left and right output pulleys 32 and 32, and the left and right laterally driven are driven at the upper ends of the left and right first universal joints 35 and 35. Each of the pulleys 36 and 36 is mounted, and the left and right laterally raised frames 37 and 37 to which the left and right laterally driven drive pulleys 36 and 36 are mounted are arranged in a rear-upward inclined posture. The rearward tilt angle of the left and right laterally raised frames 37, 37 is set larger than the rearward tilt angle of the left and right pull-out frames 15, 15. Then, left and right laterally driven driven pulleys 38, 38 are rotatably provided at the lower ends of the left and right laterally raised frames 37, 37, respectively, and the left and right laterally driven drive pulleys 36, 36 and the left and right laterally raised pulleys are provided. A plurality of lateral pulling tension pulleys (not shown) are provided between the upper and lower sides of the driven pulleys 38 and 38. Further, the left and right lateral pulling drive pulleys 36, 36, the left and right horizontal pulling driven pulleys 38, 38, and a plurality of horizontal pulling tension pulleys, a plurality of horizontal pulling lugs 39a formed of an elastic material such as rubber or sponge. Left and right laterally raised belts 39, 39 are wound around the left and right laterally raised belts 39, 39, and left and right laterally raised frames 37, 37 are parallel to the left and right laterally raised frames 37, 37. By providing the cover 40, 40, a lateral pulling device 41 is configured.

  The laterally raised lugs 39, 39... Provided on the left and right laterally raised belts 39, 39 are arranged at positions where their tip portions are close to the drawing conveyance area R of the drawing conveyance device 20 and are not in contact with each other.

  The above configuration prevents the lugs 39a and 39a from coming into contact with each other, preventing the fall of the stems and leaves caused by the impact of the contact, and reliably pulling the onion from the field by the pulling and conveying device 20. It can be pulled out and work efficiency is improved.

  Further, upper ends of the left and right second universal joints 42, 42 are provided on the lower side of the left and right output pulleys 32, 32, and left and right shoulder alignment drive pulleys 43, 43 are provided at the lower ends of the second joints 42, 42, respectively. Provide each. The left and right shoulder alignment pulleys 43, 43 are provided with front end portions of left and right upper shoulder alignment frames 44, 44 and left and right lower shoulder alignment frames 45, 45 at the upper and lower portions of the left and right shoulder alignment pulleys 43, 43, respectively. 44, and left and right shoulder-aligned driven pulleys 46, 46 are rotatably mounted on the rear end portions of the left and right lower shoulder-aligned frames 45, 45, respectively. The left and right shoulder alignment belts 50 and 50 are wound around the pulleys 46 and 46 in an endless manner.

  Further, in the branch transmission case 6, a first cutting transmission case 47a is rotatably provided on the other side of the left and right sides of the body relative to the central part in the left and right direction of the body, and a second cutting transmission is provided at the front end of the first cutting transmission case 47a. A case 47b is rotatably provided, and a cutting bevel case 48 is disposed in the left-right direction of the machine body at the front end portion of the second cutting transmission case 47b. A cutting rotary blade 49 for cutting the onion stem and leaves is detachably provided at the end of the cutting bevel case 48, and the cutting fixed blade (not shown) is placed on the upper shoulder alignment frame 44 on one side of the left or right side. ) Is detachably provided, the rise of the onion being transported by the pulling and transporting device 20 is limited by the lower shoulder alignment frames 45 and 45, and the cutting position of the foliage portion is cut to a predetermined position before cutting. 51 is configured.

  The first cutting transmission case 47a and the second cutting transmission case 47b can be configured such that the cutting height of the cutting rotary blade 49 can be freely changed by rotating in the vertical direction, so that the onion can be When the sun is dried, the cutting height is slightly left (about 3 to 5 cm), and when the onion is hung on a dryer or the like and dried, the foliage for hanging the onion is greatly increased (about 10 to 10 cm). 20 cm) The remaining cutting height.

  With the above configuration, the foliage portion is cut into the cutting rotary blade 49 and the cutting fixed blade after the cutting position is aligned to a predetermined position, so that the foliage portion is largely left uncut and the operator manually removes the foliage portion later. Since the cutting work is not necessary, the labor of the operator is reduced and the work efficiency is improved.

  Further, since the onion can be prevented from being lifted too much and the cutting rotary blade 49 and the cutting fixed blade can cut the spherical portion of the onion, so-called edible portion, the onion is not damaged and the commercial value of the onion is maintained. The

  In addition, since this cutting fixed blade overlaps with the cutting rotary blade 49 on the drawing conveyance area R, it is configured to cut across the foliage portion of the onion, and can be cut without escaping the foliage portion. The part remains without being cut, and the operator does not need to manually cut the remaining leaves.

  However, when cutting off the leaves and leaves of the onion, the edible part having the commercial value is damaged if it is cut from the vicinity of the spherical part, and the quality and the commercial value are reduced. Shall.

  In addition, by providing the cutting rotary blade 49 and the cutting fixed blade so as to be detachable, when the onion drying operation is suspended, the foliage portion can be dug up without being cut. It becomes a high crop harvester.

  On the rear side of the left and right center of the shoulder aligner 51, a guide drive case 55 provided with a guide drive pulley 52 that rotates by receiving a driving force from the branch transmission case 6 is tilted backward and tilted up and down on the rear side. A guide driven pulley 53 is rotatably provided at the lower rear portion of the guide drive case 55, and a guide belt 54 is wound around the guide drive pulley 52 and the guide driven pulley 53 to form a guide device 56. doing.

  In addition, the guide belt 54 constituting the guide device 56 is provided with lugs (not shown) at equal intervals on the outer peripheral edge, receives the stems and leaves that are left uncut and guides the onion to the top of the onion. The foliage part and root part (beard root) shall be guided to discharge onto the ridge in a posture that does not contact the field scene.

  The stems and roots of the onion, which are guided to be discharged onto the ridge, become a posture that does not contact the farm scene, so that the root that touches the soil extends into the soil and does not leave the field with a light force during recovery. Is prevented. Further, when the root portion is extended, the nutrients of the onion are consumed, so that the quality of the onion is deteriorated, but this deterioration is also prevented.

And since the foliage part which remain | survives after cutting | disconnection does not contact the field scene, when collect | recovering an onion manually, an operator becomes easy to grasp an onion and the efficiency of a collection | recovery operation improves.
With the above configuration, cultivating onion by laying multifilm etc. on the straw, the peripheries of the hole formed at the time of transplanting work and the foliage are intertwined, and the multifilm is put together at the time of pulling and harvesting the onion The guide device 56 can contact the onion through the multi-film and guide it to the lower rear side even when it is lifted to the rear, so that the multi-films are prevented from being overly overlapped when the onion falls. The removal work of the film becomes easy and the recovery work of the onion dug up on the fence becomes easy.

  In addition, since the rear side of the guide device 56 is configured to be rotatable in the vertical direction, when the guide device 56 is unnecessary, such as when harvesting onion cultivated onion where no multi-film is laid, the guide action portion is arranged on the body frame 1 side. Therefore, the crop harvester can be adapted to various working conditions.

  As described above, since the guide device 56 can come into contact with the multi-film, it is desirable that the guide belt 54 be made of a material having a weaker frictional force such as sponge than rubber in order to prevent the multi-film from being damaged.

  The onion discharged by the guide device 56 falls onto the vegetation that has been vegetated before harvesting, and is collected after harvesting or after drying in the sun. However, since a normal onion is spherical, when it is discharged, the traveling device of a working machine such as a tractor that rolls on the cage and collects the left and right drive wheels 84L and 84R, the gauge wheel 73, and the onion is recovered. May fall into a passing groove. In addition, when a 3 or 4 onion is planted in one persimmon, when the 1st or 2nd onion is harvested, the discharged onion is the unharvested side, that is, the 3rd or 4th onion. May move to the vegetation side.

  If an onion falls in the culvert groove, the worker needs to pick up the onion in the culm before collecting or collecting the onion, which reduces work efficiency and reduces the work efficiency. There is a problem that the labor of a person increases.

  Then, the worker is unaware that the onion has fallen into the trough, and the traveling devices of the working machines such as the left and right traveling wheels 84L and 84R, the gauge wheel 73, or the tractor crush the onion and lose the commercial value. Therefore, there is a problem that the yield is reduced.

  In addition, when the onion rolls down on the unharvested side, the onion that rolls up on the side of the vertical pulling device 63, the horizontal pulling device 41, and the pulling and conveying device 20 prevents the foliage from being raised or pinched and pulled out. There is a problem in that the onion of the onion is generated and the operator needs to manually pull out the onion, which increases the labor of the operator.

Furthermore, there is a problem that the vertical pulling device 63, the horizontal pulling device 41, and the pulling and conveying device 20 come into contact with the rolling onion, damaging the onion and reducing the commercial value.
In order to solve the above problem, as shown in FIGS. 1, 3, and 5, the bowl of the onion discharged from the guide device 56 to the left and right sides of the shoulder aligning device 51 and the drawing frame 15 on the left and right sides. A first guide plate 133 is provided for guiding the upper side of the shoulder while preventing it from falling into the groove, and a second guide plate for preventing the onion from falling on the unharvested strip on the left and right sides of the shoulder aligner 51. 134 is provided.

  The first guide plate 133 and the second guide plate 134 are arranged in an inclined posture in which the left-right distance is wider toward the upper side of the machine body when viewed from the front (rear). At this time, if the distance between the left and right ends of the first guide plate 133 and the second guide plate 134 is about 200 to 300 mm, which corresponds to two standard size onions, the first guide plate 133 and the first guide plate 133 2 When two onions pass side by side in the left-right direction through the narrowest part of the guide plate 134 in the left-right direction, it is necessary to interrupt the work and eliminate the clogging by clogging the gap and not moving to the rear of the machine. No work efficiency is improved.

  The first guide plate 133 and the second guide plate 134 are each made of a material such as rubber that can be elastically deformed when a strong force is applied. At this time, the lower end portion of the second guide plate 134 is separated from the farm scene, and the lower end portion of the first guide plate 133 forms a grounding portion 133b that is brought into contact with the farm scene, more precisely, the end portion of the basket. The configuration is as follows.

  Of the first guide plate 133, the ground contact portion 133b that comes into contact with the farm scene is bent when the ground contact pressure is increased by making the thickness thinner than other locations or by making a plurality of cuts to bend easily. If it is set as the structure deform | transformed, it will prevent that the 1st guide plate 133 becomes running resistance, reduces running speed, reduces work efficiency, and the 1st guide plate 133 is damaged by contact resistance.

  The second guide plate 134 has a length in the front-rear direction from the conveyance start end of the shoulder aligning device 51 to a position rearward of the conveyance end, specifically, the arrangement position of the guide drive pulley 52 of the guide device 56. On the other hand, the first guide plate 133 has a longitudinal length extending from the conveyance start end of the shoulder aligner 51 to the lower side of the branch transmission case 6, and a bent guide portion 133 a directed to the left and right other side is provided below the branch transmission case 6. Form.

  With the above-described configuration, the onion, the cutting position of which is aligned by the shoulder aligning device 51, the foliage portion is cut by the cutting rotary blade 49, and is discharged and guided onto the ridge by the guide device 56, is the first guide plate 133 and the second guide. The plate 134 is placed on the ridge that has been vegetated before being drawn and harvested and has been harvested. As a result, the onion is prevented from rolling to the side where the trough or harvesting operation is not performed.

  Therefore, it is not necessary to collect the onion that has fallen into the trough, and the next onion harvesting operation or the recovery of the onion on the reed can be performed when necessary. The labor spent by the person is reduced.

  And since there is no onion in the culvert groove, the left and right drive wheels 84L and 84R, the gauge wheel 73, or the traveling device of the work machine such as a tractor does not step on the onion, and the yield of onion can be reduced. Is prevented.

  Further, since the onion can be prevented from rolling to the side where the harvesting operation is not performed, the onion drawing and harvesting operation of the onion by the vertical pulling device 63, the horizontal pulling device 41, and the pulling and conveying device 20 is not hindered, and the work efficiency is improved. Will improve.

  Furthermore, since the vertical pulling device 63, the horizontal pulling device 41, and the pulling / conveying device 20 can be prevented from hitting or squeezing the rolled onion, the commercial value of the onion is maintained.

  Then, since the vertical length of the first guide plate 133 is such that the lower end of the first guide plate 133 is in contact with the heel, there is no gap in which the small onion moves to the heel groove, and the onion may fall into the ridge groove. It is surely prevented.

  Further, the front-rear length of the first guide plate 133 is set such that the rear end portion of the first guide plate 133 is positioned below the branch transmission case 6, so that the guide device 56 can be operated even when the machine body is traveling forward. The first guide plate 133 receives the onion that is discharged from the roll and rolls backward, so that it can be prevented from falling into the trough groove, eliminating the need for picking up the onion, reducing the labor of the worker, and improving the work efficiency. Therefore, it is possible to prevent the yield from decreasing.

  Furthermore, by forming a bending guide part 133a toward the left and right other side at the rear end part of the first guide plate 133, and by setting the rear end part of the second guide plate 134 to the upper side in the conveying direction of the guide device 56, When large sized onions are lined up, the onion can move laterally from the rear end of the second guide plate 134, so that the onion is clogged between the first guide plate 133 and the second guide plate 134. Is prevented.

Thereby, the onion is dragged and can be prevented from being damaged by the frictional resistance with the field scene, so that the commercial value of the onion is maintained.
In addition, since the onions discharged on the basket are less likely to be densely packed, the period required for drying is shortened because the ventilation and sunlight are improved when drying in the sun.

  As shown in FIGS. 1 to 4, a second branch transmission case 6a is provided on the left and right other sides of the branch transmission case 6, and is raised from the front of the second branch transmission case 6a toward the front of the machine body. 57, and a bevel case 58a is mounted on the front end portion of the output shaft 57 which is raised and changes the driving force from the left and right other sides to the left and right sides. A pair of bevel gears (not shown) are housed inside the bevel case 58a, and the driving force of the pulling output shaft 57 in the output case is vertically lifted and transmitted to the transmission shaft 58 via the pair of bevel gears. To do. Then, the longitudinally driven drive pulleys 59, 59, 59 are respectively attached to the longitudinally raised transmission shaft 58 at the left and right one side ends, the left and right other side ends and the substantially central portion in the left and right direction, and the longitudinally driven drive pulleys are mounted. A vertically raised cover 60, 60, 60 that covers both the left and right sides of 59, 59, 59 is mounted in a rear-up tilted posture and freely rotatable up and down. Further, the longitudinally driven covers 60, 60, 60 are respectively provided with longitudinally driven pulleys 61, 61, 61 at the lower end portions thereof, and the longitudinally driven driving pulleys 59, 59, 59 and the vertically driven driven pulleys 61, 61 are provided. , 61 is wound around longitudinally erecting belts 62, 62, 62 provided with a plurality of vertically elevating lugs 62a...

  It should be noted that the rearward tilt angle of the vertical pulling device 63 is substantially the same as the rearward tilt angle of the horizontal pulling device 41. As a result, the foliage portion caused by the vertical pulling device 63 is pulled up vertically and is laterally raised at a timing away from the lugs 62a, so that it is taken over by the horizontal pulling lugs 39a of the device 41. 20 can be guided to the conveyance start end portion, and the onion harvesting efficiency can be improved.

  Then, on the lower side of the left and right vertical raising covers 60, 60, there are respectively provided sag prevention covers 60a, 60a that prevent the stems and leaves that are caused to rise sideways and fall down before being taken over by the device 41. The end portions of the sagging prevention covers 60a, 60a are arranged so as to be tilted or bent toward the central vertical raising cover 60.

  As a result, it is possible to prevent the stems and leaves caused by the vertical pulling device 63 from hanging down and not being handed over to the horizontal pulling device 41, so that the onions are left without being pinched by the pulling and conveying device 20. This eliminates the need for the operator to manually pull out the remaining onion.

  Further, by arranging the rear end portions of the left and right sag prevention covers 60a, 60a toward the central vertical erection cover 60, the foliage is guided by the sag prevention covers 60a, 60a. Thus, the leaves and stems are prevented from moving away from the scraping range of 41, and the foliage portion is reliably raised and taken over by the device 41.

  Further, a gauge wheel elevating case 70 is provided at one end of the longitudinally raised transmission shaft 58 on the left and right sides, a hollow upper arm 71 is provided below the gauge wheel elevating case 70, and a gauge is provided in the hollow portion of the upper arm 71. A lower arm 72 for rotatably mounting the ring 73 is provided so as to be movable up and down. In addition, upper and lower ends of the pantograph mechanism 74 are provided on the upper arm 71 and the lower arm 72, respectively, and a fixed plate 75 is provided on the drive case 4. A turnbuckle 76 capable of adjusting the longitudinal length is provided between the fixed plate 75 and the rear portion of the gauge wheel lifting case 70, and the turnbuckle 76 is extended or contracted to move the lower arm 72 up and down. A wheel adjustment handle 77 is provided.

  With the above-described configuration, the vertical pulling device 63 and the horizontal pulling device 41 are surely connected to the onion by causing the stems and leaves of the onion hanging in the trough to fall before the gauge ring 73 steps. Since the stems and leaves can be caused, the caused stems and leaves can be pinched by the pulling / conveying device 20 and pulled out from the soil, so that the operator does not need to manually pull out the onion left behind. The effort is reduced.

  In addition, even if the shoots and leaves of the onion on the harvesting basket hang down and entangled in the trough, the shoots on the adjacent strips can be unraveled by lifting the shoots together. And the onion can be reliably pulled out by the pulling and conveying device 20.

  Then, by operating the gauge wheel adjusting handle 77 to raise or lower the lower arm 72 provided with the gauge wheel 73, the working position of the lateral pulling device 41 and the pulling / conveying device 20 can be changed according to the growth state of the onion and the height of the straw. Since it can be changed according to the height, the foliage part is pulled up and pulled out reliably, and the work efficiency is improved.

Further, as shown in FIGS. 13 and 14, the gauge wheel 73 may be driven to rotate so as to stabilize the traveling posture of the aircraft.
An extension drive shaft 58e is provided at one end of the longitudinal left and right sides (right end) of the transmission shaft 58, and a driving assist transmission that transmits the driving force from the extension drive shaft 58e to the end of the extension drive shaft 58e. A case 137 is provided, and a gauge wheel axle 138 that protrudes toward the inside of the machine body is provided at the lower end portion of the travel assist transmission case 137. Then, the gauge wheel 73 is mounted on the gauge wheel axle 138.

  The travel assist transmission case 137 is provided with elbows 137e and 137e above and below the hollow pipe 137p, respectively, and a transmission shaft 137s is provided inside the hollow pipe 137p. An input bevel gear mechanism 137vi in which a pair of bevel gears mesh with the upper end of the transmission shaft 137s and the right end of the extension drive shaft 58 is provided, and the lower end of the transmission shaft 137s and the right side of the gauge wheel axle 138 are provided. An output bevel gear mechanism 137vo in which a pair of bevel gears are engaged with the end portion is provided. The input bevel gear mechanism 137vi meshes the pair of bevel gears in the upper elbow 137e, and the output bevel gear mechanism 137vo meshes the pair of bevel gears in the lower elbow 137e.

  With the above configuration, the gauge wheel 73 can be driven and rotated via the travel assisting transmission case 137, so that the gauge wheel 73 is prevented from rotating in the left-right (yawing) direction due to the unevenness of the field and the grounding resistance. It is prevented that the advancing direction of the machine body is disturbed by the state of the surface, and the pulling and conveying device 20 fails to pull the onion from the field. This eliminates the need for the operator to collect the remaining onion, thereby reducing labor and improving work efficiency.

  The longitudinally driven transmission shaft 58 is formed in a hollow polygonal shape, for example, a hexagonal shape, and the extended drive shaft 58e is formed in a similar polygonal shape so as to be slidable in the hollow portion of the transmission shaft 58. In addition, a plurality of holes may be formed in the longitudinally raised transmission shaft 58 and the extended drive shaft 58e, and sliding may be regulated through a fixing member such as a bolt in the hole.

  In the above configuration, the left and right positions of the gauge wheel 73 can be easily changed by removing the fixing member and sliding the extended drive shaft 58e in the left and right directions. The wheel 73 is run with the wheel 73 in contact with the ground, the gauge wheel 73 touches the heel and breaks the heel and drops the onion into the heel groove, or the gauge wheel 73 rotates in the left and right (yawing) direction when touching the heel. It is prevented that the direction of travel shifts to the left and right and the efficiency of the onion drawing and harvesting work is reduced.

  Further, when adjusting the treads of the left and right drive wheels 84L and 84R, which will be described later, by moving the gauge wheel 73 to a position where the running balance can be easily achieved, the stability in the traveling direction is further improved.

Next, the structure of the traveling transmission system of this machine is shown.
As shown in FIGS. 1 to 4, a right output shaft 78R is provided on one of the left and right sides of the drive case 4, and a travel drive sprocket 79 is attached to the right output shaft 78. The travel drive sprocket 79 is attached to the right travel transmission case 80R. The interior is on the top side. Then, the right traveling transmission case 80R is in a rear-upward inclined posture, and a traveling driven sprocket 81 is rotatably mounted on the lower end side of the right traveling transmission case 80R located on the front side of the machine body. The traveling driving sprocket 79 and the traveling driven sprocket 81 The travel transmission chain 82 is wound around.

  A tension sprocket may be provided in the winding region of the travel transmission chain 82, or a clutch mechanism may be provided that prevents the breakage by retracting from the travel transmission chain 82 to stop driving when a load is applied.

  Further, an axle 83 is mounted on the traveling driven sprocket 81, and a right drive wheel 84R is provided on the axle 83. Further, left and right support plates 85 are provided at the rear upper end of the right traveling transmission case 80R, and the adjustment rod 86 is rotatable between the left and right support plates 85 and 85 and the rear portion of the upper frame 71. A swing adjusting handle 87 is provided for changing the rearward tilt angle of the right traveling case 80R by rotating the adjusting rod 86. An upper frame 71 is attached to the front end portion of the adjustment rod 86 so as to be rotatable forward and backward.

  According to the above configuration, when the tilt angle of the right driving wheel 84R is changed by operating the swing adjustment handle 87 to change the rearward rising inclination angle of the right traveling transmission case 80R, the work is performed on a field where the slope or the heel has collapsed. When changing the position, the vertical position of the right drive wheel 84R can be changed so that the aircraft can be placed in a substantially horizontal posture with respect to the field scene, so that the stems and leaves of the onion and the onion are pulled out reliably. The operator does not need to manually pull out the remaining onion, and the labor of the operator is reduced.

  Further, since the upper frame 71 is mounted on the front end of the adjustment rod 86 so as to be rotatable up and down, when the swing adjustment handle 87 is operated to rotate the right traveling case 80R up and down, the upper frame 71 is interlocked and moved back and forth. Since it rotates, the ground contact height of the gauge wheel 73 can be changed in conjunction with the vertical position of the right drive wheel 84R, the adjustment work can be easily performed, and the raising height of the foliage part of the vertical pulling device 63 is raised. Since the height is automatically adjusted to an appropriate position, the drawing and conveying work is efficiently performed.

  The right drive wheel 84R has a structure in which spokes are arranged at intervals of 120 degrees on a flange that receives the axle 83, each spoke is received by a circular rim, and a tire made of rubber or the like is attached to the outer periphery of the rim. doing.

  1 to 4 and 9, a wheel cap 130 having the same diameter as that of the right drive wheel 84R is provided on the inner side of the right drive wheel 84R and between the right drive transmission case 80R. The inner side of the right drive wheel 84R is covered. The wheel cap 130 is attached to the axle 83 with an attachment hole (not shown) to prevent dirt and sand and cut foliage from entering the space of the right drive wheel 84R from the inside of the machine body. The wheel cap 130 may be hooked on the rim or spoke of the right drive wheel 84R or fixed with a fixing member such as a bolt.

  In addition, the wheel cap 130 has a conical shape by having a configuration such that the diameter of the wheel cap 130 becomes smaller toward the right traveling transmission case 80R side on the inner side of the airframe with reference to the diameter on the side attached to the right driving wheel 84R. Thereby, it becomes a trapezoid in a cross-sectional view, and guide inclined portions 131a and 131a are formed on the upper side and the lower side of the aircraft from the outside of the aircraft toward the inside of the aircraft.

  By providing the wheel cap 130, the stems and leaves that are discharged from the leaf transport device 25 and falling, and the earth and sand that has collapsed when the onion is dug up are entangled with the spokes and the like of the right drive wheel 84R. Since it can be prevented from adhering to the drive wheel 84R, it is not necessary to remove the entangled foliage and adhering earth and sand, and the time and labor required for cleaning the aircraft are reduced.

  In addition, it can prevent the attachment of liquid with strong odor or corrosiveness that occurs when the foliage is damaged by cutting or stepping on, so the time and labor required to remove the attached liquid are reduced. .

  In addition, the wheel cap 130 has a trapezoidal shape in a cross-sectional view, and the guide inclined portions 131a and 131a are formed at the upper portion and the lower portion, respectively. At that time, when it comes into contact with the upper side of the right drive wheel 84R, that is, the upper half of the aircraft centering on a line extending in the longitudinal direction of the aircraft centering on the axle 83, it is guided inside the aircraft along the inclined surfaces 131a and 131a. Since it is guided to a position away from the right drive wheel 84R, the foliage part becomes more difficult to get entangled.

  As shown in FIG. 9, the inclined surface 131 a is formed continuously with the circumferential surface of the wheel cap 130, and the actual wheel cap 130 has a shape that is narrowed about the axle 83.

  Furthermore, since the guide inclined portions 131a and 131a having the same angle are formed on the upper side and the lower side, respectively, in a cross-sectional view, the guiding action of the foliage portion can be always achieved even when the right drive wheel 84R is rotating. The foliage is prevented from being easily caught by the rotational position of the right drive wheel 84R.

  If the wheel cap 130 is made of a material such as rubber that is relatively hard but can be easily deformed when pressed and easily returns to its original shape when not pressed, the onion is It is possible to prevent the wheel cap 130 from being damaged when it comes into contact with a paddle or a field scene.

  However, since the guide inclined portion 131a in the cross-sectional view of the wheel cap 130 has a shape that guides the foliage portion toward the inside of the machine body, the foliage portion is blown away by the rotating wheel cap 130 or blown by the wind. May move onto the bowl on which the onion is placed. The purpose of placing onions on the basket is to harvest all at once after harvesting, or to dry the sun before collection, so if the cut leaves are on the onion, it will be collected. There is an increase in the work for selecting the stems and leaves from the onion, and it is difficult for sunlight and wind to hit the onion, which increases the time required for sun drying.

  In order to prevent this, as shown in FIG. 1 to FIG. 4 and FIG. 9, an axle 83 is extended from the right side traveling transmission case 80 </ b> R toward the inside of the machine body to form an extension portion 83 a, and the extension portion A leaflet guide disk 132 is provided at 83a. The leaf guide disk 132 has the same or similar shape as the wheel cap 130. Specifically, it has a conical shape with a large inner diameter and a smaller diameter toward the outer side of the fuselage, and has a trapezoidal cross-sectional shape. Guide inclined portions 132a and 132a are formed. Therefore, the leaflet guide disk 132 may be configured such that the same parts as the wheel cap 130 are arranged in the extending portion 83a so as to be symmetrical.

  In addition, the inclined surface 132a in the cross-sectional view is formed continuously with the circumferential surface of the leaflet guide disk 132, and the actual leaflet guide disk 132 has a shape that is narrowed around the extending portion 83a. .

  Alternatively, if one of the wheel cap 130 and the leaf guide disk 132 has a smaller diameter than the other diameter, the stem and leaf portions are likely to fall off even if they enter the left and right spacing portions of the wheel cap 130 and the leaf guide disk 132. The time and labor required to remove the foliage clogged between the wheel cap 130 and the leaf guide disk 132 are reduced. The wheel cap 130 needs to match the diameter of the right driving wheel 84R, and the right and left driving transmission case 80R on which the leaflet guide disk 132 is provided and the pulling and conveying device 20 are narrow and there are other components. It is desirable that the leaf guide disk 132 has a smaller diameter than the wheel cap 130.

  Like the wheel cap 130, the leaflet guide disk 132 may be made of rubber or the like that has a relatively high hardness and easily deforms when pressed and returns to its original shape when no pressure is applied. . In particular, since the leaflet guide disk 132 is disposed at a position approaching the cocoon, there are many opportunities to come into contact with the onion and the cocoon. Is done.

  In addition, the leaflet guide disk 132 is a drop that keeps the onion to move into the trough in the trough, when the onion is cut by the shoulder aligning device 51 and the foliage is cut and dropped onto the trough. Since it also functions as a prevention plate, it is possible to prevent crushing onions that have fallen into the troughs, to prevent the yield of onions from decreasing, and to eliminate the work of collecting onions that have fallen into the troughs, The labor of the worker can be reduced and the work efficiency can be improved.

  In addition to the above, the wheel cap 130 is not fixed to the right drive wheel 84R, but is provided on the axle 83 so as to be freely rotatable (free rotation) via a bearing or the like, and the leaf 83 is discharged to the extending portion 83a of the axle 83. The guide disk 132 may be mounted so as to rotate in conjunction with the rotation of the axle 83.

  By providing the wheel cap 130 so as to be able to rotate freely without being affected by the rotation of the right drive wheel 84R, it is possible to prevent the earth and sand in the field from being lifted upward by the rotation, so that the lifted earth and sand adhere to each part of the aircraft. This reduces the time and labor required to remove the earth and sand, and prevents breakage due to earth and sand clogging.

  Further, the leaflet guide disk 132 provided on the inner side of the machine body is rotated in conjunction with the rotational drive of the right drive wheel 84R, so that the foliage discharged from the leaflet transfer device 25 is guided to the front side of the machine body by the leaflet guide disk 132. Therefore, the foliage is prevented from being entangled with the airframe, and the time and labor required for the removal work can be reduced.

  At this time, the stems and leaves that are discharged and guided by the wheel cap 130 and the leaf guide disk 132 are likely to move onto the right traveling transmission case 80R, so that the upper surface of the right traveling transmission case 80R is configured to be flat.

  Since the right-side traveling transmission case 80R is provided in a downward inclined posture toward the front side of the aircraft, if the upper part is configured flat, the fallen foliage part will easily slide down toward the front side of the aircraft, so The discharge is performed reliably.

  Further, as shown in FIGS. 10 (a) and 10 (b), an infinite number of conical, spherical, etc. leaflet protrusions 135a are formed on the surface of either or both of the wheel cap 130 and the leaflet guide disk 132. May be formed, or an infinite number of leaflet hair bodies 135b may be provided to prevent the stems and leaves from sticking to the wheel cap 130 and the leaflet guide disk 132.

  Alternatively, as shown in FIGS. 11 and 12, the right traveling transmission case 80 is disposed on the outer side of the right driving wheel 84R, and the right driving wheel 84R extends toward the outer side of the right traveling transmission case 80. The wheel cap 130 and the leaf guide disk 132 are provided at a predetermined interval so as to be symmetrical between the right and left sides of the right drive wheel 84R and the drawing / conveying device 20 (or the machine frame 1). It can also be configured.

  The wheel cap 130 and the leaf guide disk 132 are provided in an extending portion 83a extending toward the inner side of the machine body so as to rotate in conjunction with the rotational drive of the extending portion 83a. At this time, a collar 136 that is not interlocked with the driving rotation of the extending portion 83a is provided between the wheel cap 130 and the leaf guide disk 132 so as to be freely rotatable.

  The wheel cap 130 and the leaf guide disk 132 are respectively formed with a first width adjusting groove 130a and a second width adjusting groove 132a, and the collar 136 is formed with the first width adjusting groove 130a or the second width adjusting groove 132a. The distance between the wheel cap 130 and the leaflet guide disk 132 may be configured to be changeable by moving the inside of one of the above, both inside, or both outside.

  As shown in the above configuration, since the right traveling transmission case 80R is disposed outside the fuselage with respect to the right drive wheel 84R, the right traveling transmission case 80R is not in a position that obstructs the discharge guidance of the foliage, so that the foliage is the wheel. Since it becomes easy to fall to the field from the right and left gap between the cap 130 and the leaf guide disk 132, the time and labor required to remove the tangled leaves are further reduced.

  Further, by moving the collar 136 to the first width adjusting groove portion 130a and the second width adjusting groove portion 132a, the wheel cap 130 and the leaf guide disk 132 can be moved left and right along the extending portion 83a to change the left-right distance. Therefore, the left and right intervals can be determined in accordance with the thickness and amount of the foliage, and the foliage is prevented from clogging the left and right intervals of the wheel cap 130 and the leaflet guide disk 132.

  Alternatively, since the left and right positions of the left and right spacing portions between the wheel cap 130 and the leaf guide disk 132 can be adjusted, the stems and leaves can be discharged to a position away from the top of the cocoon, making it difficult for the foliage to ride on the top. The foliage can be discharged to a position away from the right drive wheel 84R to make it difficult to get entangled with the right drive wheel 84R.

  As shown in FIGS. 2 and 3, a left output shaft 78L is slidably provided in the left and right other ends of the second branch transmission case 6a on the left and right other sides of the machine body, and is provided at the rear of the second branch transmission case 6a. A mounting plate 88 is provided, and the mounting plate 88 and the drive case 4 support the fixed side 89 a of the tread adjusting cylinder 89. Then, a travel drive sprocket 79 is mounted on the left output shaft 78L, and the travel drive sprocket 79 is installed in the upper part of the left travel transmission case 80L. Further, the left traveling transmission case 80L is in a rear-upward inclined posture, and a traveling driven sprocket 81 is rotatably mounted on the lower end side of the left traveling transmission case 80L located on the front side of the aircraft, and the traveling driving sprocket 79 and the traveling driven sprocket 81 are provided. The travel transmission chain 82 is wound around. Further, an axle 83 is mounted on the traveling driven sprocket 81, and left driving wheels 84L are provided on the axle 83.

  When the moving side 89b of the tread adjusting cylinder 89 is connected to the upper end portion of the left traveling transmission case 80L, and the tread adjusting cylinder 89 is extended, the moving portion 89b and the left transmission shaft 78L move in the left and right directions. The left traveling transmission case 80L is separated from the body frame 1, and the right and left distance between the right driving wheel 84R and the left driving wheel 84L is increased. On the other hand, when the tread adjusting cylinder 89 is contracted, the moving portion 89b and the left transmission shaft 78L move in the left-right direction so that the left traveling transmission case 80L approaches the body frame 1 and the right drive wheel 84R and the left The left and right intervals of the drive wheels 84L are configured to be narrow.

  With the above configuration, the left and right drive wheels 84L can be changed in left and right positions according to the left and right width of the rod. Therefore, it is necessary to move the left drive wheels 84L on the rod when working in a field with different left and right widths of the rod. The onion can be extracted and harvested in a stable posture, improving work efficiency.

  Further, when loading the airframe onto a loading platform such as a light truck or storing it in a warehouse or the like, the left-right distance between the left and right drive wheels 84L, 84R can be reduced to the limit, thereby reducing the left-right width of the airframe. As a result, loading and storage of the aircraft can be performed efficiently.

  In addition, if the wheel cover which prevents the stem and leaf part of the onion hanging from the adjacent strip from being entangled with the spoke or the axle 83 is detachably provided on the inner peripheral portion of the right drive wheel 84R, the stem and leaf part is entangled and adjacent to the inner periphery of the right drive wheel 84R. It is prevented that the onion of the strip is pulled out and cannot be drawn and harvested by the drawing / conveying device 20, and the work efficiency is improved.

  The onion planted in the soil is located at a certain depth depending on the setting at the time of transplanting the seedling, but the height of the cocoon varies depending on the formation work and the subsequent wind and rain, etc. If the vertical height of 29 is not changed, there may be some problems such as the soil cannot be sufficiently solved and many roots remain.

  In order to prevent the above problem, as shown in FIGS. 19 and 20, the vertical position of the swinging soy 29 is detected at the front of the machine body of the vertical adjustment arm 111 and at the rear side of the bifurcated branching support 111a. A detection rotation arm 114 provided with a potentiometer 113 is provided, and a grounding rotator 116 that contacts the field is provided below a horizontal rotation shaft 115 that is a rotation fulcrum of the detection rotation arm 114. The grounding rotator 116 includes a roller 116a that rotates due to grounding resistance, and a spring 116b that moves the roller 116a up and down to rotate the detection turning arm 114 up and down when the roller 116a passes through the unevenness of the field. However, the unevenness of the fine field is ignored by the spring 116b, and the unevenness of the large field is configured to prevent damage due to excessive resistance due to expansion and contraction of the spring 116b.

  When the rotation angle of the rotation detection arm 114 detected by the potentiometer 113 changes, the vertical adjustment cylinder 109 expands or contracts in accordance with the change amount of the angle, and the vertical adjustment arm 111 rotates up and down to swing the rocking soiler. The vertical position of 29 is finely adjusted.

  A vertical height marker 117 indicating the vertical position of the oscillating sour 29 is provided on the upper part of the rotary plate 103, and the height of the soyer is set above the rotary shaft 115 of the rotary detection arm 114. In addition to supporting the posture of the height marker 117, an indicator 118 indicating the reference height from the farm scene is provided in the vertical direction. The indicator 118 has an L shape in which a bent portion 118a is formed at the upper end portion in front of the machine body in a side view, and a U-shaped space portion is formed in the bent portion 118a. The upper side of the height marker 117 is exposed. A plurality of scales are provided on the upper side of the soiler height marker 117, and the operator reads the working depth of the rocking soy 29 from the length protruding from the upper end of the indicator 118.

  Further, a long hole 119 in the vertical direction is formed on the upper end side of the indicator 118, and at least two depth detection sensors 120d and 120s are provided in the long hole 119. The depth detection sensors 120 d and 120 s are constituted by photoelectric sensors or proximity sensors, and are provided on the front side of the indicator 118 so as to be movable in the vertical direction along the long hole 119, and the depth on the rear side of the indicator 118. A fixing member such as a butterfly bolt that restricts the movement of the detection sensors 120d and 120s is provided, and the vertical positions of the detection sensors are arranged to be adjustable.

  Note that one depth detection sensor 120d detects that the working height of the swinging sour 29 is on the “deep” side, and the other depth detection sensor 120s is that the working height of the swinging sour 29 is “shallow”. Therefore, if a partition plate for restricting the vertical movement range of the depth detection sensors 120d and 120s is provided in the long hole 119, the detection position can be easily set.

  In the above description, the two depth detection sensors 120d and 120s detect “shallow” and “deep”, but three or more depth detection sensors may be provided to detect the depth more finely. .

  Then, on the front side of the indicator 118 and below the bent portion 118 a, a detected ring 121 in which the depth detection sensors 120 d and 120 s recognize the depth of the swinging soiler 29 is attached to the soiler height marker 117. When one of the depth detection sensors 120d and 120s detects the detected ring 121 during the onion drawing harvesting operation, the vertical adjustment cylinder 109 is expanded or contracted by a predetermined amount, and the vertical adjustment arm 111 is moved upward or downward. , And the vertical position of the rocking soiler 29 is adjusted.

  When traveling is stopped, or when the drawing / conveying device 20 and the vertical pulling device 63 are stopped, the vertical adjustment cylinder is detected even if the depth detection sensors 120d and 120s detect the detected ring 121. 109 is configured not to expand and contract. The above determination is made based on the operation positions of the travel operation lever 10 and the work operation lever 11.

  The soyler height marker 117 is made of a flexible metal such as a wire coated with a resin such as vinyl chloride, or an elastic material made of rubber or synthetic resin. It is set as the structure which can prevent both damage by bending. Further, the upper end of the soira height marker 117 is lit or flashed when either of the depth detection sensors 120d and 120s is in a detection state, and visually notifies the operator of the detection. A detection lamp 122 such as an LED is provided.

  The lighting and flashing of the detection lamp 122 also operates when the potentiometer 113 that detects the rotation angle of the detection rotation arm 114 detects a change in the rotation angle and expands and contracts the vertical adjustment cylinder 109. Shall. At this time, if the detection lamps 122 are provided in two upper and lower stages, the upper stage lights up when the depth detection sensors 120d and 120s are detected by the detected ring 122, and the lower stage lights up when an angle change of the potentiometer 113 is detected. It becomes easy for a person to grasp which height control is performed. Alternatively, the blinking pattern of one detection lamp 122 may be different.

  The detection lamp 122 may be energized by a method using a wire constituting the soiler height marker 117 in addition to a method of arranging a cable along the solitary height marker 117. At this time, the wire is provided with a coating or cover made of highly insulating rubber or synthetic resin so that the energizing portion is not exposed.

  With the above configuration, when the vertical adjustment cylinder 109 is expanded and contracted to change the vertical position of the rocking soy 29, the operator grasps how much the operator moves up and down while looking at the positional relationship between the indicator 118 and the height marker 117 of the soy. As a result, it is easy to adjust the working height of the rocking soiler 29, to make sure that the soil around the onion is unraveled and to make it easy to extract and harvest, and the root of the onion is easy to be cut, and after harvesting. This reduces the time and effort required for the preparation.

  When the angle of the rotation detection arm 114 detected by the potentiometer 113 is changed due to unevenness when the grounding rotating body 116 is brought into contact with the farm field, the vertical adjustment cylinder 109 expands and contracts and the vertical position of the rocking sour 29 is changed minutely. By doing so, the operating position of the swing soiler 29 due to the unevenness of the field can be adjusted to an appropriate position, so that the swing soiler 29 is prevented from contacting the onion and damaging the onion, and the commercial value of the onion is reduced. Is prevented.

On the other hand, since the rocking soy 29 can be prevented from moving too far downward from the onion, the root of the whisker is easily cut during the harvesting operation, and the time and labor required for the preparation operation after the harvesting are reduced.
Further, when there is a large unevenness such that either one of the depth detection sensors 120d and 120s detects the detected ring 121, the depth detection sensors 120d and 120s detect the detected ring 121 and at the same time, adjust the vertical adjustment cylinder 109. Since the working height of the swinging soiler 29 can be moved to the “shallow” side or the “deep” side, the working height can be increased even in a situation where a significant change in the working height of the swinging sour 29 is required. Can be automatically adjusted to an appropriate position, so that it is possible to prevent the onion from being damaged and reduce the commercial value, and to facilitate the post-harvest preparation.

  When the depth detection sensors 120d and 120s are in the detection state, the vertical adjustment cylinder 109 is expanded and contracted in preference to the operation of the vertical adjustment cylinder 109 due to the angle change of the rotation detection arm 114 detected by the potentiometer 113. The configuration.

  Further, when the depth detection sensors 120d and 120s are in the detection state, the detection lamp 122 is turned on or blinks so that the operator can visually recognize the detection state, so that the operator can automatically move the vertical position of the rocking sour 29. The pulling and harvesting work can be done by grasping that it is adjusted, so there is no need to operate the vertical adjustment lever at unnecessary timing, and the work efficiency is improved.

  In the above, the shape of the rocking soiler 29 is L-shaped when viewed from the front. However, as shown in FIG. 21, the vertical mounting portion 29z attached to the sora support arm 105 and the lower part of the onion enter the soil to unravel the soil. At the same time, a bent portion 29x having a V-shape in front view is formed between the action portions 29y in the left-right direction for removing the root of the hair.

  The bent portion 29x includes a vertically inclined portion 29w that is inclined 20 to 30 degrees from the mounting portion 29z toward the other left and right sides of the machine body, and a left and right end portion of the action part 29y from the lower end portion of the vertically inclined part 29w. Left and right inclined portion 29v inclined upward. The above-described shape is formed by bending the swinging soiler 29.

  Further, in order to make the swinging solubilizer 29 easily bite into the soil, the swinging sour 29 is configured to retreat about 5 degrees from the outer end of the body toward the inner end of the body in plan view. The receding angle is formed with the end facing the rear side of the machine body in a plan view when the left and right inclined portions 29v are formed.

  Furthermore, when forming the up-and-down inclined portion 29w, the base portion side of the rocking soiler 29 enters the soil in advance by bending the end portion of the up-and-down inclined portion 29w toward the front side of the machine body. .

  With the above configuration, the boundary between the up-and-down inclined portion 29w and the left-right inclined portion 29v of the swinging soluer 29, that is, the bent portion 29x precedes the portion and enters the dredger, and the action portion 29y moves in the dredged soil in a retracted posture. Therefore, the lowering of the unraveling action and the root cutting action of the rocking soy 29 due to the resistance of the soil is prevented, the work efficiency is improved, and the time and labor required for the post-harvest preparation work are reduced.

  Moreover, since the rocking soiler 29 can be made to enter from the lower part of the side surface of the fence, the soil can be unwound from the lower side of the laid multi-film, and therefore the work of collecting the multi-film after excavating the onion from the field Can be performed, and work compatibility is widened.

About the crop harvester for this onion harvest, the modification of the soira which digs an onion is shown as follows.
As shown in FIGS. 15 and 16, wire receiving rollers 139, 139 are provided on the left and right vertical raising covers 60, 60, and an adjuster 140 for adjusting the tension is attached to the sora swing case 107. , 139 and the adjuster 140, the swinging wire 141 is wound endlessly.

  The swinging wire 141 is directed downward from one of the left and right wire receiving rollers 139 through the other wire receiving roller 139, and in the downward direction via the adjuster 140, the lower portion of the rocker swinging case 107 extends in the left-right direction. It passes through and is folded upward and returned to the wire receiving roller 139, and is looped around.

  With the above configuration, the swinging wire 141 passes under the two onions, and the earth and sand around the onion can be swung and loosened, so that the onion can be easily pulled out from the field, and the onion remains on the field. Is prevented.

  In addition, by changing the tension of the swing wire 141 with the adjuster 140, the swing amount of the swing wire 141 can be changed in accordance with the soil quality of the field. Can be pulled out.

Then, since the earth and sand around the onion is unwound by the swing wire 141, the exchange can be easily performed, so that the time and labor required for the replacement work can be reduced in the event of breakage.
As shown in FIGS. 17 and 18, a longer wire can be mounted by changing the base portion of the swing wire 141 to the wire winding drum 142 instead of the wire receiving roller 139 on the left and right sides of the machine body. Therefore, the adjustment range of the tension by the adjuster 140 is widened, and the part damaged by the contact with the earth and sand is cut with a nipper or a gold cutter etc., and the unused swing wire 141 is pulled out to be ground and act. As a result, the replacement work is further facilitated.

  Further, a plurality of the swing wires 141 may be arranged side by side in the front-rear direction. By arranging a plurality, the range of soiling in the front-rear direction is widened, so that the soiling action is further improved, and the onion can be reliably pulled out from the field.
