As a result, the second empty cardboard box stand 36 and the support legs 37 can be stored without projecting the second empty cardboard box stand 36 from the side surface of the traveling machine body 2.

Next, the flow of the harvesting work of crop A will be described. As shown in FIG. 2, the harvesting trolley 1 is operated by the operator H1 boarding the control unit 4 and moves in the field along with the hand harvesting worker H2 who manually collects the crop A from the field. As shown in FIGS. 1 to 3, a plurality of empty cardboard boxes 34 are placed on the first and second empty cardboard box stands 35 and 36, respectively.

The hand-harvesting worker H2 sequentially puts the collected crop A into the horizontal feed conveyor 14. For example, prior to harvesting crop A, stem root cutting and preparation work is performed in advance with a kitchen knife or the like, and when harvesting crop A, the hand-harvesting worker H2 picks up the prepared crop A from the field and feeds it sideways. It is put into the conveyor 14. The hand-harvesting worker H2 may collect the crop A from the field while performing the stem root cutting and preparation work, and put the crop A into the lateral feed conveyor 14 each time. Further, the crop A may be loaded into the horizontal feed conveyor 14 not only from the rear side of the horizontal feed conveyor 14 but also from the front side of the horizontal feed conveyor 14. It is also possible to put the crop A into the horizontal portion 15b of the vertical feed conveyor 15.

For example, when the crop A is cabbage for raw consumption, the inter-row spacing is, for example, 450 mm, and the planting density is higher than when harvesting with a vegetable harvester (for example, the inter-row spacing is 600 mm). The total length of the lateral feed conveyor 14 is, for example, about 2100 mm, and the lateral feed conveyor 14 can be arranged over four crops A. In this embodiment, for example, two hand-harvesting workers H2 collect and input crop A.

Further, in this embodiment, the control unit 4 is arranged on the front right side of the traveling machine body 2, the vertical feed conveyor 15 is arranged on the front left side of the traveling machine body 2, and the horizontal feed conveyor 14 is arranged on the left front side of the traveling machine body 2.

As a result, the operator H1 boarding the control unit 4 can check the work status of the hand harvester H2 with good visibility while operating the harvest trolley 1, so that the work progress of the hand harvester H2 can be adjusted. The harvesting trolley 1 can be operated, and accidents due to contact between the harvesting trolley 1 and the hand harvesting worker H2 can be prevented.

The crop A introduced into the horizontal feed conveyor 14 by the hand harvester H2 is inherited by the vertical feed conveyor 15, and is conveyed onto the traveling machine body 2 and sent to the rotary table base 21. As shown in FIG. 2, the assistant H3 who got on the traveling machine 2 took out the cardboard box 34 from the empty cardboard box stand 35 or 36, placed it on the workbench 25, and sent the crops to the rotary table stand 21. A is sequentially housed in the cardboard box 34. The assistant H3 moves the cardboard box 34 filled with a predetermined amount of crop A to the packed box stock stand 26, and takes out another cardboard box 34 from the empty cardboard box stand 35 or 36 on the empty workbench 25. Place and continue boxing work. Of the crops A sent from the vertical feed conveyor 15 to the rotary table table 21, the crop A that was not packed in time by the assistant H3 was circulated and transported on the rotary table table 21 and was transported to the left side of the workbench 25. Return to.

The cardboard box 34 in which the crop A is stored is sequentially stacked on the pallet 30 supported by the fork 32 of the hydraulic vertical lift 31 by the assistant H3 or the assistant H4 mounted on the auxiliary work step 29. After the desired amount of cardboard boxes 34 are stacked on the pallet 30, the unloading operation is performed. In the unloading work, the hydraulic lifting mechanism 33 of the hydraulic vertical lift 31 is lowered to lower the fork 32 and the pallet 30 until the lower surface of the pallet 30 touches the ground, and then the traveling machine body 2 is advanced to move the fork 32 from the pallet 30. Pull out and place the pallet 30 on the ground. After that, the hydraulic lifting mechanism 33 of the hydraulic vertical lift 31 is raised to raise the fork 32 to a predetermined position, a new pallet 30 is arranged on the fork 32, and the harvesting operation of the crop A is resumed. The pallet 30 on which the cardboard box 34 in which the crop A is packed is collected by a forklift or the like.

Further, since the harvesting carriage 1 includes a lateral feed conveyor 14 that conveys crops in the lateral direction with respect to the traveling direction of the traveling machine 2, as shown in FIG. 2, the harvesting carriage 1 straddles the crops A for a plurality of rows. The lateral feed conveyor 14 can be arranged. As a result, the hand-harvesting worker H2 does not have to carry and move the collected crop A simply by placing it on the horizontal feed conveyor 14 on the spot, and the labor of the hand-harvesting worker H2 is reduced. In addition, the time required for carrying and moving is reduced and the harvesting efficiency is improved.

Further, since the harvesting trolley 1 is provided with a rotary table stand 21 capable of rotating the crop A on the traveling machine 2, for example, when the boxing work by the assistant H3 (worker) is not in time, the crop A is rotated on the rotary table stand. It can be lapped on 21. As a result, the assistant H3 can carry out efficient sorting and adjustment work without changing the work speed.

Further, in the vertical feed conveyor 15, the horizontal portion 15b (upstream portion of transport) is supported by the traveling machine body 2 so as to be able to move up and down, and the horizontal feed conveyor 14 is supported by the horizontal portion 15b of the vertical feed conveyor 15. The height positions of the horizontal portion 15b and the lateral feed conveyor 14 can be adjusted according to the degree of subduction of the traveling machine body 2, the height of the ridges, the height of the crop A, and the like. As a result, the versatility for the field conditions, crop types, crop growth conditions, etc. is improved.

Further, the horizontal feed conveyor 14 can be folded and stored so that its longitudinal direction is along the longitudinal direction of the vertical feed conveyor 15, and the rotary table stand 21 can be folded and stored so that the transport surface of the crop is in an upright state. It is possible to realize a compact harvesting carriage 1 by reducing the portion protruding in the vehicle width direction with respect to the traveling machine 2. Further, in the harvesting trolley 1 of this embodiment, the packed box stock pedestal 26 and the auxiliary work step 29 can be stored so as to fit within the vehicle width of the traveling machine 2, and therefore, by storing these, the entire width of the harvesting trolley 1 can be obtained. Can be made smaller. Further, since the second empty cardboard box stand 36 arranged toward the outside of the traveling machine 2 during the harvesting work is configured to be removable, the entire width of the harvesting cart 1 can be increased by removing the second empty cardboard box stand 36. Can be made smaller.

Further, in the harvesting carriage 1, since the traveling machine 2 is provided with the traveling crawler 3, it is possible to handle the work in the field after rain, the wetland, the sloping land, etc., which cannot be performed by the wheel type traveling device.

Next, a modified example will be described.

The fall prevention member 39 is arranged along the longitudinal direction of the lateral feed conveyor 14. When the tilt angle of the vertical feed conveyor 15 is adjusted by the expansion and contraction movement of the hydraulic cylinder 17, the transport surface of the horizontal feed conveyor 14 is not always horizontal. In this modification, by arranging the fall prevention member 39, it is possible to prevent the crop A from falling even when the transport surface of the lateral feed conveyor 14 is inclined.

Further, as shown in FIG. 8, a second horizontal feed conveyor 40 for transporting the crop A to the left side may be provided on the right side of the horizontal portion 15b of the vertical feed conveyor 15. In this embodiment, the horizontal feed conveyor 40 is arranged symmetrically on the horizontal feed conveyor 14 with the vertical feed conveyor 15 interposed therebetween. By providing the horizontal feed conveyor 40, the crop A collected in front of the traveling machine body 2 can be conveyed to the vertical feed conveyor 15 by the horizontal feed conveyor 40. As a result, the harvesting carriage 1 can be moved in the field while harvesting the crop A in front of the traveling machine 2 in the course direction, and the crop A can be harvested before being crushed by the traveling crawler 3 or the like. The horizontal feed conveyor 40 is connected to the right side of the horizontal portion 15b of the vertical feed conveyor 15 via the rotary fulcrum shafts 41 and 42 and the conveyor connecting portion 43, and can be folded and stored in the same manner as the horizontal feed conveyor 14. Have.

Further, as shown in FIG. 8, a pallet mounting portion 44 may be provided instead of the hydraulic vertical lift 31 (see FIGS. 1 to 3). The pallet mounting portion 44 is composed of a space on which the pallet 30 provided on the rear right side of the traveling machine body 2 can be mounted. In this modified example, the auxiliary work step 29 is extended to the rear side, and the rearward portion of the auxiliary work step 29 constitutes a part of the pallet mounting portion 44.
