  The protruding length s1 from the left and right auxiliary raising cases 133L and 133R and the central auxiliary raising cases 133CL and 133CR of the auxiliary raising lug 63y is determined by the left and right raising cases 62L and 62R and the central raising case of the raising lug 63x. Even if the leaf and leaf portion is lying on the multi-film, the auxiliary pull-up lug 63y is raised and the leaf and leaf portion of the onion O is caused before the lug 63x. It is possible to raise the foliage part without breaking the multi-film and to cause the nail 63aa to take over the foliage part. The torn multi-film causes the left and right devices 64L and 64R and the central pulling device 64C and the left and right auxiliary pulls. Devices 137L and 137R, left and right auxiliary pulling devices 137CL and 137CR, and left and right pulling and conveying devices 49L and 49R Interruption of work due to clogged convoluted by eliminating, to improve work efficiency.

  Further, by causing the stem part to be raised by the soft raising claw 63ab constituting the auxiliary raising lug 63y and causing the hard raising claw 63aa constituting the lug 63x to be raised, the foliage part is caused to rise right and left and to the center 64L, 64R, 64C and the left and right and central auxiliary pulling devices 137L, 137R, 137CL, 137CR can be prevented from falling off, so that the left and right pulling and conveying devices 49L, 49R are less likely to fail to grasp the foliage, and the operator pulls out. The work of manually pulling out the onion O left after the work is omitted, and the labor of the operator is reduced.

  Further, the left and right auxiliary pulling devices 137L and 137R pull the left and right transmission shafts 132L and 132R left and right from the lower outer surface of the cases 62L and 62R and attach them to the driven sprockets 61 and 61, thereby mounting the left and right pulling case 62L. , 62R can be lifted at a position away from the onion O, so that the foliage can be lifted with a light force to be taken over by the left and right pulling and conveying devices 49L, 49R. Since the operator manually removes the onion O that has not been pulled out and is not pulled out after the harvesting operation, the labor of the worker is reduced.

  Then, the raising and driving sprockets 60, 60, 60 of the left and right and center raising devices 64L, 64R, 64C are attached to the transmission shaft 58a built in the transmission case 58 so as to be rotatable in the vertical direction of the machine body. . Furthermore, among the left and right and central pulling devices 64L, 64R and 64C, a plurality of holes are formed on the outer sides of the left and right pulling plates 65 and 65 attached to the outer surfaces of the left and right pulling devices 64L and 64R. The left and right elevating support arms 66, 66 each having a long hole formed in the hole in the vertical direction are combined and attached with a fixing member such as a bolt, and the ends of the elevating support arms 66, 66 are raised to the support frame 50.

Further, weeds 67, 67, 67 for lifting the stems and leaves of the onion O are attached to the lower parts of the left and right and center pulling devices 64L, 64R, 64C, and the stems and leaves are scraped back to the weeds 67, 67, 67. The harvesting and conveying apparatus C is configured by attaching the scraping members 68, 68, 68 to be sent to.

  According to the above configuration, by providing the pair of left and right pulling / conveying devices 49L and 49R that pull out and convey the onion O by the inner pinching and conveying belt 38 and the outer pinching and conveying belt 45, respectively, even if the two onions O are pulled out. Since the pulling and transporting devices 49L and 49R each hold only one stalk and leaf portion of the onion O, it is prevented that the pulling and transporting devices 49L and 49R are clogged with the stem and leaf portion of the onion O and work efficiency is improved. At the same time, since the work of removing the foliage that the operator has clogged is omitted, the labor of the operator is reduced.

  In addition, by driving the inner sides of the left and right pulling / conveying devices 49L and 49R with the drive pulleys 31CL and 31CR respectively attached to the two output shafts of the central transmission case 30C, the transmission configuration of the machine body can be simplified and the number of parts can be reduced. Since it can be reduced, resource saving can be achieved.

  Further, left and right inner side clamping auxiliary frames 40, 40 having a plurality of inner side clamping auxiliary rollers 35 attached to the outer side of the machine body, and left and right outer side clamping auxiliary frames 40, 40 having a plurality of outer side clamping auxiliary rollers 41 attached to the inner side of the machine body. Since the clamping force on the clamping conveyance starting end side of the left and right extraction conveyance devices 49L and 49R that clamp the stem and leaves of the onion O and extract it from the field can be strengthened, the remaining onion O remains less. The work efficiency is improved and the work of the operator to harvest the onion O left over manually is omitted, so the labor of the worker is reduced.

  The left and right outer clamping auxiliary frames 40, 40 are provided so as to be rotatable in the left-right direction of the machine body with the rotation fulcrum P serving as a fulcrum. When the operator pivots the left / right opening / closing levers 42, 42 outward and pulls them, the left / right outer holding auxiliary frames 40, 40 are moved toward the outer side of the machine to change the holding state of the left / right pulling / conveying devices 49L, 49R to the holding / conveying start end side. Since it can be released, even if foreign matter such as foliage and stones of onion O are bitten on the clamping conveyance starting end side of the left and right pulling conveyance devices 49L and 49R, the operator can easily cancel the biting state. Work efficiency can be improved. In addition, when the left and right opening / closing levers 42 and 42 are turned to the inside of the machine during work, the left and right opening / closing levers 42 and 42 do not interfere with the drawing / conveying work, so that the work efficiency is improved.

  In addition, by attaching a soira 53 that digs up the soil around the onion O in the soil, it is possible to easily extract the onion O even in a hard soil field, so there is less leftover of the onion O. The efficiency is improved, and the worker's labor of harvesting the onion O left by hand is omitted, so that the labor of the operator is reduced. Furthermore, since the load applied to the left and right drawing / conveying devices 49L and 49R during drawing is reduced, the durability of each member constituting the left and right drawing / conveying devices 49L and 49R is improved, and the life of the machine body is extended.

  Then, the hard raised claws 63aa and the soft raised claws 63aa and the soft raised claws 63ab are inserted into the fitting bolts 63c attached to the lug base 63b to attach the hard raised claws 63aa and the soft raised claws 63aa.

  Further, by forming one or a plurality of groove portions 63e between the tip portion and the base portion of the fitting bolt 63c, a foliage portion is caused in the hard raising claw 63aa and the soft raising claw 63ab attached to the fitting bolt 63c. Even if it is pulled due to resistance, it pulls up in the groove 63e and hooks the claw 63a, so that the pulling claw 63a is prevented from coming off during the operation, so the left and right pulling and conveying devices 49L and 49R fail to grip the foliage. This prevents the operator from pulling out the onion O remaining in the field after the harvesting operation, thereby reducing the labor of the operator.

  If the groove 63e has a tapered shape with a diameter smaller than the diameter of the fitting bolt 63c toward the tip side, it can be prevented from being caught by the groove 63e when the raised claw 63a is attached. As the efficiency is improved, it is possible to prevent the claw 63aa and the soft claw 63ab from coming off during the operation due to the resistance force that pulls up the foliage as described above. And the operator's labor is reduced by omitting the work of pulling out the onion O remaining in the field after the harvesting work.

  Further, as shown in FIG. 9, the front end of the fitting bolt 63c is made larger than the diameter of the base of the fitting bolt 63c and the diameter of the space 63f formed in the hard raising claw 63aa and the soft raising claw 63ab. You may form in a large diameter. In this configuration, once the hard-lifting claw 63aa and the soft-lifting claw 63ab are attached to the fitting bolt 63c, it can withstand a greater resistance than the above-described groove 63e having a tapered shape, and the hard-lifting claw 63aa and It is possible to more firmly prevent the soft nail and the nail 63ab from coming off.

  The fitting bolt 63c for inserting the hard raising claw 63aa and the soft raising claw 63ab is fixed to the lug base 63b with the nut 64d, so that the hard raising claw 63aa and the soft raising claw 63ab are caused by breakage or change of working conditions. , The nut 64d can be loosened to remove the fitting bolt 63c from the lug base 63b, and can be replaced with a fitting bolt 63c into which another hard raising claw 63aa and soft raising claw 63ab is inserted. improves. In particular, when the groove 63e has a tapered shape as described above, it is difficult to remove the claw 63a by being raised from the fitting bolt 63c. The efficiency is improved, and it is not necessary to remove the claw 63a by applying an excessive force, so that it is possible to prevent the damage when the claw 63a is lifted and removed from the fitting bolt 63c.

Thus, the effort to remove the root of onion O is reduced.

  Further, the left and right pressing and conveying devices 91L and 91R are configured to be rotatable in the vertical direction of the machine body with the left and right drive shafts 82, 82, 82 and 82 as the rotation fulcrum, so that the left and right pressing can be performed according to the size and shape of the onion O. Since the transfer devices 91L and 91R automatically move up and down, the onion O can be prevented from being clogged between the left and right press transfer devices 91L and 91R and the root processing devices 79L and 79R, so that the work efficiency is improved.

  And by receiving the driving force of the left and right press conveying devices 91L and 91R from the left and right output pulleys 84, 84, 84 and 84 of the root processing devices 79L and 79R by the pressing drive pulleys 86, 86, 86 and 86, transmission Since the number of parts can be reduced, resource saving can be achieved, and the machine structure can be simplified and maintainability can be improved.

  Furthermore, since the tension pulley is not required by pressing the conveying belt side of the pressing belts 90, 90, 90, 90 with the pressing drive pulleys 86, 86, 86, 86, resource saving can be achieved.

  In addition, the onion is cut without leaving the foliage by attaching the foliage cutting blades 99, 99, 99, 99 for cutting off the foliage of the onion O to the lower end of the telescopic rotating shafts 98, 98, 98, 98. When harvesting O, the rotation shafts 98, 98, 98, 98 can be extended to cut the entire foliage part, and when cutting the foliage part in order to hang the foliage part on a wire or the like and dry it, the rotation axis 98, 98, 98, 98 can be shrunk and only the upper part of the foliage can be cut, so that the harvesting can be performed according to the drying operation method after the harvesting operation, the work efficiency is improved, and the foliage is cut forward. When the drying operation is performed, it is not necessary for the operator to manually remove the foliage portion, so that the labor of the operator is reduced.

  The left and right leaflet conveying devices 102L and 102R are driven by the leaflet driving pulleys 94CL and 94CR attached to the two output shafts of the central rear transmission case 93C, respectively, thereby simplifying the transmission configuration of the body. In addition, since the number of parts can be reduced, resource saving can be achieved.

  Further, the conveyance start end portions of the left and right leaf conveyance devices 102L and 102R are disposed above the conveyance terminal portions of the left and right press conveyance devices 91L and 91R, and the conveyance terminal portions of the left and right pressure conveyance devices 91L and 91R and the left and right leaf leaf conveyance devices 102L. , 102R, the left and right pressing and conveying device before the stem and leaf portion of the onion O is sandwiched between the left and right discharged leaf conveying devices 102L and 102R by arranging the foliage cutting blades 99, 99, 99, 99 behind the conveying start end portion. Since 91L and 91R press onion O, the root part of onion O can be cut reliably with root processing devices 79L and 79R, so that the work efficiency is improved and the operator manually removes the onion O root. Effort to reduce.

  In addition, since the left and right defoliation transport devices 102L and 102R hold the foliage portion of the onion O in a state where the onion O is pressed against the root processing devices 79L and 79R, the foliage portion can be cut at an appropriate position. The onion O is prevented from being damaged and the commercial value of the onion O is maintained.

Next, the storage unit E will be described.
As shown in FIGS. 1, 2, 4, and 11 to 15, the rear end of the root processing devices 79 </ b> L and 79 </ b> R and the lower end of the left and right leaflet transfer devices 102 </ b> L and 102 </ b> R and A take-over shooter 105 is attached to the main frame 1 in a tilted rearwardly inclined posture in the front-rear direction of the machine body and substantially the same as the left and right widths of the root processing devices 79L and 79R, and behind the take-up shooter 105 and on the main frame 1 A hopper 106 for storing the onion O having a lateral width substantially the same as the lateral width of the takeover shooter 105 is attached. Then, the base of the bottom plate 107 is attached to the bottom of the outer side of the body of the hopper 106 in the direction of the inner side of the body, and the bent portion 107a is formed to be bent downward at the inner end, and the base of the bottom plate 107 is used as the center of rotation. It can be opened and closed freely.

  Further, a base portion of a guide plate 108 that guides the onion O falling from the hopper 106 on the cage and to the already-excavated side of the onion O is attached to an inner bottom portion of the hopper 106, and the base portion of the guide plate 108 is used as a rotation fulcrum. The storage part E is comprised by comprising an edge part so that rotation to an up-down direction of a body is possible.

In the present embodiment, the bottom plate 107 is configured to be openable and closable, but the bottom plate 107 may be configured to be detachable.
According to the above configuration, by attaching the hopper 106, the onion O can be stored in the hopper 106 even when the number of the harvested onion O is large. Since there is no need to temporarily stop the transporting devices 49L and 49R and the root processing devices 79L and 79R to interrupt the harvesting operation of the onion O, work efficiency is improved.

  Further, since the bottom plate 107 is inclined downward toward the inside of the machine body, the onion O riding on the bottom plate 107 can automatically slide down and move toward the conveyance start end of the sorting and conveying conveyor 116 described later. When O is small, the onion O is prevented from staying in the storage part E, and the work efficiency is improved.

In addition, by forming the bent portion 107a bent downward at the inner end of the machine body of the bottom plate 107, the above-mentioned retention prevention effect is further enhanced, and the work efficiency is further improved.
In addition, since the space part W of the extent which the onion O does not fall between the bending part 107a and the selection conveyance conveyor 116 is formed, the mud etc. adhering to the onion O can be dropped to the field, so the selection It becomes difficult for mud or the like to adhere to the transport conveyor 116 or the accommodating portion G, and the labor required for cleaning after work is reduced.

  Since the bottom plate 107 is attached so as to be freely opened and closed, when the onion O is collected in the accommodating portion G, the bottom plate 107 is closed to store the onion O from the hopper 106, and the onion O is dried on the reed. Then, when collecting with a dozer or the like later, the bottom plate 107 can be opened and the onion O can be switched to drop onto the straw from the hopper 106, so that the work according to the variety of onion O and the state of the field can be performed. The work efficiency is improved and the quality of the onion O is improved.

  Further, since the guide plate 108 is attached so as to be rotatable in the vertical direction of the machine body, the onion O can be guided to the top of the basket after the onion O is pulled out and harvested by rotating the guide plate 108. Therefore, it is possible to prevent the onion O from rolling down to the ridge groove due to the momentum of the fall, preventing the left and right traveling crawlers 19L and 19R from stepping on the onion O falling into the ridge groove. In addition to maintaining the value and preventing the onset of the onion O from the left and right traveling crawlers 19L, 19R, the work of stopping the machine and manually collecting the onion O by the operator is omitted. The labor of the person is reduced.

  Further, since the onion O falling from the hopper 106 can be prevented from colliding with the onion O planted on the unharvested side of the persimmon, the onion O falling and the onion O planted on the unharvested side can be prevented. It is prevented from being damaged by the collision at the time of falling, the commercial value of the onion O is maintained, and the onion O that has fallen on the unharvested side is planted on the unharvested side. , And it is prevented that the unharvested onion O is difficult to be pulled out by the left and right pulling and conveying devices 49L and 49R, so that the unharvested onion O can be smoothly pulled out and work efficiency is improved. .

Next, the sorting and conveying apparatus F will be described.
As shown in FIG. 1, FIG. 2, FIG. 11, FIG. 13 and FIG. 15, the front and rear sorting frames 109F and 109R are attached to the inner side of the fuselage from the inner end of the hopper 106, and the front and rear sorting is performed. A drive roller 110 is rotatably attached between the front and rear of the lower end sides of the transport frames 109F and 109R, and a drive motor 111 that rotates the drive roller 110 is attached to one of the front and rear sorting transport frames 109F and 109R. A driven roller 112 is rotatably attached between the front and rear of the front and rear sorting and conveying frames 109F and 109R, and the sorting and conveying belt 113 that conveys the onion O to the driven roller 112 and the driving roller 110 is made endless. Wrap it around. On the surface of the sorting and conveying belt 113, a plurality of protrusions 114 are formed to prevent the onion O from falling downward.

  In addition, a plurality of tension plates 115 for preventing slack of the sorting and conveying belt 113 are attached in the winding area of the sorting and conveying belt 113 and between the driving roller 110 and the driven roller 112, and the upper surface is opened. A sorting and conveying conveyor 116 is configured.

  Then, a discharge shooter 117 is attached to the transfer terminal portion of the sorting and conveying conveyor 116, and an auxiliary worker performs sorting and the like behind the machine body from the sorting and conveying conveyor 116, and a box 122 that is a container 122 that stores the onion O The rear step 119 for placing the container 122a, the flexible container 122b, and other tools necessary for the harvesting operation is performed from the vicinity of the transfer start end of the sorting transfer conveyor 116 to the outer end of the main frame 1 where the harvest transfer device C is provided. And attach. Further, a U-shaped auxiliary seat frame 120 in a side view is attached to the rear portion of step 119 and behind the transfer start end portion of the sorting and conveying conveyor 116, and the upper portion of the auxiliary seat frame 120 is directed toward the sorting and conveying conveyor 116. A sorting and conveying apparatus F is configured by rotatably mounting an auxiliary seat 121 on which an auxiliary worker sits on the adjacent protruding portion and performs sorting operation of the onion O and the like.

  According to the above configuration, since the plurality of protrusions 114 are formed on the surface of the sorting / conveying belt 113, the onion O can be prevented from dropping from the sorting / conveying conveyor 116, and the onion O is damaged by the impact of the dropping. Is prevented, and the quality of onion O is improved.

  In addition, since the upper surface of the sorting / conveying conveyor 116 is open, the auxiliary worker can visually sort out and remove defective products (scratches, rots, small grains, malformations, etc.) from the onion O being conveyed. Since the work of removing defective products after the work is omitted, the labor of the worker is reduced.

  Since the auxiliary work seat 121 is attached to the protruding portion close to the sorting and conveying conveyor 116 in the upper part of the auxiliary seat frame 120, the auxiliary worker can perform the sorting operation of the onion O while sitting. The labor of auxiliary workers is reduced.

  Further, since the auxiliary work seat 121 is rotatably attached, the auxiliary worker can place the container 119 placed on the step 119 while sitting on the auxiliary work seat 121 in the accommodating portion G. Therefore, the labor of auxiliary workers is reduced.

Next, the accommodating part G is demonstrated.
As shown in FIGS. 11 to 16, an accommodation bottom plate 123 is disposed on the main frame 1 behind the steering device 11, below the terminal end of the sorting and conveying conveyor 116, and above the left traveling crawler 19 </ b> L and the left auxiliary traveling wheel 126 </ b> L. Then, the front and rear wall members 124F and 124R are attached to the front and rear end portions of the receiving bottom plate 123, and the inner wall member 125 is attached to a position below the terminal end portion of the sorting and conveying conveyor 116. Further, a plurality of attachment hooks 127, 127,... Are attached to the outer side surfaces of the front and rear wall members 124F, 124R at equal intervals in the vertical direction of the body, and the container is provided on the outer side surface of the front and rear wall members 124F, 124R at the lower end. The loading carrier 129 is configured by mounting the mounting table 128 on which the mounting unit 122 is mounted in a tilted state in which the outer end portion is positioned above the base portion and is rotatable.

  Further, a box-shaped container 122a is placed on the accommodation bottom plate 123 from the open part S outside the machine body of the loading carrier 129, and if necessary, the container 112a is placed on the container 122a placed on the accommodation bottom plate 123. Put. Alternatively, the front and rear suspension arms 130F and 130R are rotatably attached to the outside of the upper ends of the front and rear sorting and conveying frames 109F and 109R constituting the sorting and conveying conveyor 116, and the onion O is accommodated in the front and rear suspension arms 130F and 130R. A bag-like container 122 such as a bag-like flexible container 122 b is suspended and placed in the loading carrier 129. The containers 122a such as the container 122a and the flexible container 122b are prevented from falling on the mounting hooks 127, 127, ... according to the vertical height of the container 122a placed on the loading carrier 129 or the vertical height of the flexible container 122. The detachable support plate 131 is attached at a predetermined interval from the outer side end of the load carrier 129 to the outer side, thereby forming the accommodating portion G.

  The vertical height of the front and rear wall members 124F and 124R is lower than about 110 to 130 cm, which is the viewpoint height of the auxiliary worker sitting on the auxiliary seat 121, and three box-shaped containers 122a are arranged in the vertical direction. When the height is approximately the same as about 90 to 100 cm, the auxiliary worker confirms the storage state of the onion O stored in the container 122a or the flexible container 122b in the loading carrier 129 while sitting on the auxiliary seat 121. Therefore, it is possible to urge the operator to stop the machine body and the left and right drawing / conveying devices 49L and 49R, and to prevent the onion O from overflowing from the container 122a, the flexible container 122b, or the loading carrier 129, and the impact of dropping. The onion O is prevented from being damaged, and the commercial value of the onion O is maintained. Workers and auxiliary workers there is no need to gather, effort of the worker is reduced.

  In addition, the support plate 131 has substantially the same length in the front-rear direction of the mounting table 128, the outer end position is matched with the outer end position of the mounting table 128, and the receiving portion on which the container 122a can be mounted inside. When the container 122a is formed, the container 122a can be placed on the placing table 128 while preventing the container 122 such as the container 122a from dropping out of the apparatus, and the capacity of the flexible container 122b can be increased. This increases the amount of onion O that can be recovered in the process, improving work efficiency. In addition, since it is not necessary to frequently unload containers 122 such as the container 122a and the flexible container 122b from the loading carrier 129, the labor of the operator is reduced.

  The interval when the support plate 131 is attached to the outer side from the outer end of the stack carrier 129 is set to be approximately the same as the width of the container 122a, so that a plurality of containers 122a are additionally stacked on the stack carrier 129. Therefore, the number of times of unloading the container 122a from the machine body can be reduced, so that the work efficiency is improved and the labor of the worker is reduced. In addition, since the load of the container 122a is increased, the onion O can be divided and accommodated in a plurality of containers 122a, so that the weight of the onion O loaded on the bottom of the container 122a is stacked on the upper side. Is prevented from being damaged, and the commercial value of onion O is maintained.

  Further, when using the flexible container 122b, the flexible container 122b that is as large as the width of the container 122a can be used, so that a large number of onions O can be collected at a time, so the number of times the container 122a is unloaded from the aircraft is reduced. As a result, the work efficiency is improved and the labor of the worker is reduced.

  Even when the onion O is directly put into the loading carrier 129, since the capacity of the loading carrier 129 is large, a large number of onions O can be accommodated at a time, so the onion O is discharged from the loading carrier 129. The number of operations can be reduced, the work efficiency is improved, and the labor of the worker is reduced.

  According to the above configuration, by mounting the mounting plate 128 so as to be rotatable, even if the space for mounting the container 122a is insufficient with the receiving bottom plate 123 alone, the extended bottom plate 124 is expanded to mount the container 122a. Therefore, it is not necessary to frequently replace the container 122a, and the labor of the operator is reduced. Also, it is not necessary to stop the machine body every time the container 122a is replaced, so that the work efficiency is improved. .

  Further, even when the front-rear width and the left-right width of the flexible container 122b are larger than the front-rear width and the left-right width of the accommodation bottom plate 123, the entire width of the flexible container 122b is expanded to the accommodation bottom plate 123 and the extended bottom plate 124 by unfolding the mounting plate 128. Since the onion O can be accommodated up to the accommodation limit of the flexible container 122b, there is no need to frequently replace the flexible container 122b, and labor of the operator is reduced, and the flexible container 122b is replaced. This eliminates the need to stop the aircraft every time, improving work efficiency.

  After the work is completed, the left and right widths of the airframe can be shortened by rotating the mounting plate 128 inward of the airframe, so that the airframe may protrude from the loading platform when loaded on a transport means such as a truck. Thus, the safety of the airframe transport operation is improved, and it is prevented that extra space is consumed when the airframe is stored in a warehouse or the like.

  Furthermore, since the mounting table 128 can be adjusted to an inclined state in which the outer end portion is located above the base, the container 122a mounted on the mounting table 128 is inclined in accordance with the inclination of the mounting table 128. Since the container 122a can be prevented from moving to the outside of the machine body and falling to the outside of the machine, the onion O is prevented from being damaged by the impact of the drop, and the commercial value of the onion O is maintained, and the operator can avoid the onion O Since the work of collecting the container 122a is omitted, the labor of the operator is reduced.

  Further, since the outer end portion of the mounting table 128 is positioned above the base, the foliage of the onion O comes into contact with the mounting table 128, and the foliage of the onion O is entangled with the mounting table 128 and broken. Therefore, since it is possible to prevent the left and right pulling / conveying devices 49L and 49R from being pulled out, it is not necessary for the worker to manually pull out the onion O which has not been pulled out after the harvesting operation by the vegetable harvesting machine. The labor is reduced and the work efficiency is improved.

  By attaching a plurality of attachment hooks 127, 127... At equal intervals in the vertical direction of the body and attaching a detachable support plate 131 to the attachment hooks 127, 127. The container 122 such as the container 122a or the flexible container 122b moves in the direction of the open portion S of the outer side of the body of the loading carrier 129 according to the vertical height of the stacked container 122a or according to the capacity of the flexible container 122b. Therefore, the onion O is prevented from being damaged by the impact of the drop, and the commercial value of the onion O is maintained, and the operator does not need to pick up the onion O or the container 122. Labor is reduced.

  Further, since the accommodation bottom plate 123 constituting the loading carrier 129 is positioned above the left traveling crawler 19L and the left auxiliary traveling wheel 126L, the onion O is accommodated in the loading carrier 129 and applied to the loading carrier 129. Even if the weight increases, the balance of the aircraft can be maintained, so that the vehicle's running posture is stable and accidents such as rollovers are less likely to occur, and the safety of work is improved.

  Furthermore, since it is possible to prevent the pulling positions of the left and right pulling / conveying devices 49L and 49R from being shifted, the operator does not have to manually pull out the onion O which has not been harvested after the harvesting operation by the vegetable harvesting machine. The labor efficiency is reduced and the work efficiency is improved.

The loading carrier 129 may directly store the onion O without placing the container 122 such as the container 122a or the flexible container 122b.
According to the above-described configurations A to G, the harvesting and conveying device C, the preparation device D, the storage unit E, the sorting and conveying device F, and the accommodating unit G are placed on the main frame 1 that is located below the upper frame 2 in the vertical direction. Since the height of the airframe can be lowered by providing the airframe, the airframe size becomes compact and the airframe can be stored in a warehouse with a low ceiling.

Hereinafter, another embodiment of the onion harvester will be described.
As shown in FIG. 23, even if one or a plurality of protrusions 138 are formed between the base portion and the tip end portion of the hard-lifting claw 63aa and the soft-lifting claw 63ab which are the stem and leaf portion raising action surfaces. good.

  According to the above configuration, the foliage portion of the onion O caused by the hard-raised claw 63aa and the soft-raised claw 63ab is caught by the protrusion 138, so that the foliage portion is hard-raised and falls off the claw 63aa and the soft claw 63ab. Therefore, the stems and leaves are surely taken over by the left and right nipping and conveying devices 49L and 49R, and there is less leftover of onion O, so that the work efficiency is improved and the onion O left by the operator manually is removed. Since the harvesting work is omitted, the labor of the worker is reduced.

  In addition, when the protrusion 138 is hard-raised and inclined toward the base of the claw 63aa and the soft-raised claw 63ab, the foliage part is better caught and the foliage part can be more reliably prevented from falling off.

  As shown in FIG. 24, the drive pulley 139 and the driven pulley 140 are pulled up in the left and right and center pulling cases 62L, 62R and 62C, and the driven drive pulley 139 and the driven pulley 140 are A belt with a lug made of an elastic body such as rubber and formed with a plurality of raising lugs 142 formed of an elastic body such as rubber and having a shape inclined upward from the middle between the tip and the tip. 141 is wound endlessly. Then, a core member 143 having a T-shape in a side view is disposed inside each of the plurality of raising lugs 142... So that the front end portion is raised and is positioned substantially at the same position as the upward inclined starting portion of the lug 142.

  According to the said structure, by providing the core material 143 inside each of the several raising lugs 142 ... formed in the belt 141 with a lug, the raising lugs 142 bend by the resistance which raises the foliage part of the onion O, Since the foliage can be prevented from falling off, the foliage is reliably transferred to the left and right nipping and conveying devices 49L and 49R, the amount of onion O remaining is reduced, and the work efficiency is improved. Since the work of harvesting the remaining onion O is omitted, the labor of the operator is reduced.

  In addition, since the leading end of the core member 143 is raised and disposed at substantially the same position as the upward slope start portion of the lug 142, the leading end of the lug 142 continues to retain elasticity, so that the multi-film laid in the field Since the multi-film is prevented from being broken even if it touches, the broken multi-film is pulled up in the left and right and the center, and the work is interrupted by clogging the devices 64L, 64R and 64C and the left and right nipping and conveying devices 49L and 49R. Can be prevented.

  As shown in FIG. 25, when the leading end portion of the core member 143 is raised to extend toward the leading end side from the upward inclination starting portion of the lug 142, and the extending portion is in the upward inclined posture, the foliage is formed at the upward inclination starting portion. Since the upper inclined part can be prevented from being bent due to the resistance of the foliage when the foliage is caused, the foliage is reliably taken over by the left and right nipping and conveying devices 49L and 49R, and the onion O is removed. The remaining amount is reduced and the work efficiency is improved, and the worker's work of harvesting the onion O left manually is omitted, so the labor of the worker is reduced.

  As shown in FIG. 26, the drive pulley 145a and the auxiliary pull-up drive sprocket 146a are arranged side by side on the left and right and center raising cases 144L, 144R, and 144C, respectively, and the left and right and center raising cases 144L, 144R, The driven pulley 145b and the auxiliary driven and driven sprocket 146b are arranged side by side with the driven pulley 145b. The pulling drive pulley 145a and the driven pulley 145b are wound endlessly on a pulling belt 148 formed with a plurality of pulling lugs 147 formed of an elastic body such as rubber, and the auxiliary pulling The auxiliary elevating chain 150, which is mounted so that the auxiliary elevating lugs 149, which are made of resin such as plastic, are accommodated in the non-operating area on the elevating drive sprocket 146a and the auxiliary elicited driven sprocket 146b. It is possible to form the left and right and center pulling devices 151L, 151R, and 151C by winding.

  The pulling lug 147 and the auxiliary pulling lug 149 are made of an elastic material when the pulling lug 147 causes the stem and leaf part of the onion O from the field scene to immediately assist and the lug 149 takes over the stem and leaf part. Before the stem and leaf part drops off from the flexible pulling lug 147, it can surely be handed over to the auxiliary pulling lug 149 made of resin and not bent, so the stem and leaf part is surely taken over by the left and right nipping and conveying devices 49L and 49R. The remaining amount of onion O is reduced and the work efficiency is improved, and the worker's work of harvesting the onion O left manually is omitted, so the labor of the operator is reduced.

  According to the above configuration, the foliage part is caused from the field scene with one raising case, and the caused foliage can be taken over to the left and right holding and conveying devices 49L and 49R, so that the number of parts can be reduced and resource saving can be achieved. And cost reduction.

  In addition, as shown in FIG. 27, when the raising lug 147 is arranged on the heel end side (the outer side of the machine body) and the auxiliary raising lug 149 is arranged on the inner side of the cocoon (the inner side of the machine body), the raising lug 147 is a leaf portion of the onion Can be surely caused even if it hangs down at the end of the heel, so that the foliage is reliably taken over by the left and right nipping and conveying devices 49L and 49R, the remaining onion O is reduced and the work efficiency is improved. Since the work of harvesting the onion O left over manually is omitted, the labor of the operator is reduced.

  As shown in FIG. 28 and FIG. 29, the pulling driven pulley 152b is attached to the left and right and center pulling cases 62L, 62R, and 62C so as to be rotatable at a substantially intermediate position and movable in the front-rear direction, respectively. A pulling belt 154 in which a plurality of pulling lugs 153... Made of an elastic material such as rubber are formed between the pulling driven pulley 152b and a pulling driving pulley 152a receiving a driving force from the auxiliary pulling driven sprocket 146b. Each may be wound endlessly.

According to the above configuration, the length of the raising belt 154 and the number of raising lugs 153 can be reduced, so that resource saving and cost reduction can be achieved.
Further, the pulling drive pulley 152a for rotating the pulling belt 154 is rotated by receiving the driving force from the auxiliary sprocket 146b, so that the transmission structure can be simplified, so that productivity and maintenance are improved. To do.

  Since the pulling and driven pulley 152b is movable in the front-rear direction, the tilting angle of the pulling belt 154 can be changed, so that the stems and leaves of the raised onion O are pulled and the lugs 153 of the belt 154 are raised. The auxiliary pull-up lug 149 attached to the chain 150 can be handed over while being retracted, so that mistakes in taking over the foliage can be reduced.

  As shown in FIGS. 30 and 31, a plurality of lug bases 63b attached to the raising chain 59 are provided with a soft raising claw 63ab and a hard raising having a length L1 shorter than the length L2 of the soft raising claw 63ab. It is good also as a structure which attaches the nail | claw 63aa alternately.

  According to the above configuration, since the soft nail 63ab causes the foliage of the onion O, the hard nail 63aa can take over the foliage as soon as the claw 63ab causes the foliage of the onion O. As a result, there is less leftover of onion O and the work efficiency is improved, and the work of harvesting onion O left manually by the operator is omitted, so the labor of the operator is reduced.

  Moreover, since both the softly raised claw 63ab and the hard raised claw 63aa are attached to a single raised chain 59, the number of parts can be reduced, so that the maintainability is improved and the number of parts and the cost are reduced. Reduction is planned.

  As shown in FIGS. 32 and 33, a linear hard raising claw 155 is attached to a plurality of lug bases 63b attached to the raising chain 59, and a base portion and a distal end portion are disposed above the distal end portion of the hard raising claw 155. It is also possible to adopt a configuration in which the elastic body raising claw 156 in an upward inclined posture bent upward from the substantially middle position is detachably attached via the attachment plate 157. Note that the mounting plate 157 is also hard raised and detachable from the claw 155.

  According to the above configuration, the stem and leaf portion of the onion O that has been caused by the elastic body and caused by the claw 156 can be hardly raised and handed over to the claw 155, so that the stem and leaf portion is prevented from falling off and the onion O is left behind. As a result, the work efficiency is improved, and the work of harvesting the onion O left manually by the worker is omitted, so that the labor of the worker is reduced.

  Further, since the elastic body is raised and the claw 156 always acts on the foliage portion first, it is prevented from breaking even if it comes into contact with the multi-film, so that the torn multi-film is caused to rise left and right and in the center, and the devices 64L, 64R, 64C. In addition, it is possible to prevent the operation from being interrupted by clogging the left and right nipping and conveying devices 49L and 49R.

  Since the elastic body is raised and the claw 156 is hard and the upper part of the claw 155, the foliage portion that is hard and is inherited by the claw 155 is elastically raised and is prevented from dropping off at the rear end of the claw 156. The stems and leaves are surely taken over by the left and right nipping and conveying devices 49L and 49R, the amount of leftover of the onion O is reduced, the work efficiency is improved, and the work of harvesting the onion O left by the operator is omitted. As a result, the labor of the operator is reduced.

  Further, when the stems and leaves of the onion O are not hanging on the multi-film or when working in an open field where the multi-film is not laid, the elastic body is raised from the hard raised nail 155 and the nail 156 and the mounting plate 157 are removed. Therefore, it is possible to perform appropriate work according to work conditions, and work efficiency is improved.
