  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. Then, the container 122 such as the container 122a or the flexible container 122b is dropped 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 to the stacking carrier 129 from the outer end of the machine body at a predetermined distance from the outer end of the stack carrier 129, 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 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 substantially 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.

  A plurality of mounting 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 a detachable support plate 131 is attached to the mounting hooks 127, 127,. By attaching the container 122 such as the container 122a or the flexible container 122b according to the vertical height of the stacked container 122a or according to the capacity of the flexible container 122b, the open portion S direction of the outer side of the body of the loading carrier 129 Therefore, the onion O is prevented from being damaged by the impact of a drop, the commercial value of the onion O is maintained, and the operator's work of picking up the onion O and the container 122 is omitted. , Labor of workers 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.

  According to the above configuration, the load carrier 129 is in a balanced state by setting the rotation shaft 132 serving as the rotation fulcrum of the load carrier 129 above the left traveling crawler 19L in the rear view. The loading carrier 129 can be manually rotated to the outside of the machine body, and the container 122a placed on the accommodation bottom plate 123 and the flexible container 122b full of onion O can be lowered onto the field or road. Labor is reduced. In addition, when the loading carrier 129 is rotated in the direction toward the inside of the machine body, the operator can move the loading carrier 129 with substantially the same force.

  Note that when the loading carrier 129 is rotated in the outer direction of the machine body, if the mounting table 128 is opened, the container 122a and the flexible container 122b can be operated as a shooter to move out of the machine, and the container can be smoothly moved. Since the 122a and the flexible container 122b can be discharged out of the apparatus, work efficiency is improved.

  As shown in FIG. 18, the storage bottom plate 123 constituting the loading carrier 129 is configured to be rotatable in the vertical direction of the machine body with the outer side of the machine body as a base, and an onion O is placed on the lower end side of the storage bottom plate 123. It is good also as a structure which attaches the movement control board 133 which prevents falling from the top.

  According to the above configuration, when the harvested onion O is left on the basket to be dried in the sun, the onion O put into the loading carrier 129 is guided to the top by rotating the receiving bottom plate 123 downward. Therefore, the work of arranging the onion O on the basket manually by the worker or the auxiliary worker after the harvesting work is omitted, and the work efficiency is improved.

  In addition, since the movement restriction plate 133 is attached to the lower end of the housing bottom plate 123, it is possible to prevent the onion O from rolling down from the trough, so that the onion O that has fallen into the trough is moved by the traveling crawler 19L or the left auxiliary traveling wheel. In order to prevent crushing by 126L and improve the commercial value of the onion O, and avoiding the onion O that has fallen into the ridge groove from being crushed by the traveling crawler 19L or the left auxiliary traveling wheel 126L, Since the harvesting operation is interrupted and the operation of picking up the onion O that has fallen into the trough by the worker or auxiliary worker is omitted, the work efficiency is improved.

  The onion O harvested from the 1st and 2nd rows opens the bottom plate 107 of the hopper 106 and drops, and the onion O harvested from the 3rd and 4th rows opens the accommodation bottom plate 123 and drops the onion O. It can be placed so that it doesn't get too crowded on top, and it will improve the efficiency of sun drying and improve the efficiency of sun drying. Can be shortened.

  As shown in FIG. 19, the harvesting of the adjacent onion O from the bottom end of the transport of the front and rear sorting transport frames 109 </ b> F and 109 </ b> R constituting the sorting and transporting conveyor 116 to the lower end outside the body of the loaded carrier 129 is completed. A discharge shooter 134 for moving the onion O is attached so as to be rotatable in the vertical direction of the machine body. A bucket 135 for storing a plurality of onions O is attached to the discharge side of the discharge shooter 134, and the upper end of the bucket 135 extends from the upper end of the bucket 135 to the terminal end of the discharge shooter 135. It is good also as a structure which attaches the lid | cover 136 to rotate so that rotation to the up-down direction of a body is possible.

  Note that the length of the discharge shooter 134 is longer than the vertical length of the load carrier 129, so that the onion O is discharged into the load carrier 129, and the load carrier 129 is left after the worker or auxiliary worker has finished the work. Since the work of placing the onion O on the coffin is omitted, the work efficiency is improved and the distance between the discharge part of the discharge shooter 134 and the eaves is shortened, and the onion O may be damaged by the impact of the drop. It is prevented and the commercial value of onion O is maintained.

  According to the above configuration, when the onion O harvested by the discharge shooter 134 is discharged onto the adjacent basket after the harvesting operation, the discharged onion O collides with the uncollected onion O and is damaged. Therefore, the commercial value of the onion O is maintained and the stems and leaves of the onion O that has not been harvested are pushed down and cannot be pulled out by the left and right pulling / conveying devices 49L and 49R. Since the work of manually pulling out the onion O from the field after the harvesting work is omitted, the work efficiency is improved.

  Further, by attaching the bucket 135 to the discharge side of the discharge shooter 134, an operator or an auxiliary worker can discharge a plurality of onions O in one place, so that the sun-dried onions O are collected. Can be efficiently recovered.

  Since the pivot fulcrum of the lid 136 is the pivot fulcrum of the bucket 135, the onion O can be discharged without contacting the lid even when the lid 136 is opened and closed. It is prevented from being damaged, and the durability of the aircraft is improved.

  Furthermore, since the discharge shooter 134 is configured to be rotatable, the discharge shooter 134 can be rotated so that the onion O can be dropped at an appropriate position on the heel. It can be sun-dried, and the time required for natural drying of onion O is shortened.

  As shown in FIGS. 20 (a) and 20 (b), the pulling device that causes the stems and leaves of the onion O is composed of left and right pulling devices 137, 137 and a central pulling device 138, and on both left and right sides of the central pulling device 138. Left and right guide guides 139 and 139 for guiding the stems and leaves of onion O caused by the central pulling device 138 to the left and right pulling and conveying devices 49L and 49R are attached. And it is also possible to attach a sag prevention cover 140 that prevents the long foliage part from drooping to the next drawing / conveying device 49L or 49R side at the center in the left-right direction of the central pulling device 138 and at the bottom on the front side of the machine body. good.
