[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings, an embodiment of the present invention will be described in detail.

[0024] The same applies below, but some components may not be shown in the drawings, or may be shown in a perspective or simplified manner.

[0025] While explaining the operation of the vegetable transplanter of this embodiment, a work vehicle operation control method of an invention related to the present invention, which is realized by a controller, etc., will also be explained.

[0026] The vegetable transplanter of the present embodiment is a specific example of the work vehicle of the present invention.

[0027] (1) First, the configuration and operation of a vegetable transplanter according to an embodiment of the present invention will be specifically described with reference to FIGS. 1 to 4 and 5(a) to 5(c).

[0028] Here, Figure 1 is an oblique view of a vegetable transplanter of an embodiment of the present invention, Figures 2 to 4 are oblique views (parts 1 to 3) of the vicinity of main frame 1101 of a vegetable transplanter of an embodiment of the present invention, and Figures 5(a) to 5(c) are oblique views (parts 1 to 3) of the vicinity of main frame 1101 of a vegetable transplanter of a modified embodiment of the present invention.

[0029] The left side clutch device 110 and the right side clutch device 120 are clutch devices that are released by pulling the left side clutch cable member 210 and the right side clutch cable member 220, respectively, in response to a side clutch operation by a walking operator at the steering handle device 20.

[0030] The left side clutch cable locking member 310 is a movable cable locking member that is locked with the left side clutch cable member 210. The right side clutch cable locking member 320 is a movable cable locking member that is locked with the right side clutch cable member 220.

[0031] The left side clutch cable locking member 310 and the right side clutch cable locking member 320, which are provided by utilizing roller members or the like, are inserted into the cable middle portions of the left side clutch cable member 210 and the right side clutch cable member 220, respectively, so that the direction of the side clutch cables is smoothly changed so that they are directed from the main frame 1101 toward the grip portion of the steering handle device 20.

[0032] The side clutch lever member 500 is a lever member that moves in response to a side clutch lever operation by an operator on board.

[0033] In a vegetable transplanter in which an auxiliary step 1202 for an operator who inserts seedlings into a seedling cup 41 is provided above the rear wheel 1201 on one of the left and right sides of the vehicle body, the operator can easily adjust the vehicle body's traveling direction with the side clutch lever member 500. Since there are ups and downs in a farm field, it is not easy to operate the steering handle position from the auxiliary step position. However, when an operator who is standing or sitting on the auxiliary step 1202 wants to turn on and off the left side clutch device 110 and the right side clutch device 120 to make subtle adjustments to the vehicle body's traveling direction, he or she can safely steer from the step by operating the side clutch lever member 500 as a dedicated lever provided near the center upper end of the main frame 1101.

[0034] The right side clutch lever acting member 420 as one side clutch lever acting member connected to the left side clutch cable engaging member 310, and the left side clutch lever acting member 410 as the other side clutch lever acting member connected to the right side clutch cable engaging member 320 are arranged to face each other.

[0035] By using a roller arm member or the like to attach the left side clutch cable locking member 310 and the right side clutch cable locking member 320 to the right side clutch lever acting member 420 and the left side clutch lever acting member 410, respectively, cable pulling can be reliably performed by moving the cable locking members.

[0036] The side clutch lever member 500 is inserted into the space between the right side clutch lever action member 420 and the left side clutch lever action member 410 .

[0037] Since the side clutch lever member 500 is inserted into the gap between the right side clutch lever action member 420 and the left side clutch lever action member 410, the right side clutch lever action member 420 and the left side clutch lever action member 410, as well as the left side clutch cable locking member 310 and the right side clutch cable locking member 320, can be operated without any hindrance by only the single side clutch lever member 500.

[0038] It is to be noted that a modified embodiment in which one side clutch lever acting member is the left side clutch lever acting member 410 and the other side clutch lever acting member is the right side clutch lever acting member 420 may also be considered.

[0039] However, the right side clutch lever acting member 420 and the left side clutch lever acting member 410 are combined crosswise like the blades of a pair of scissors, and the axial direction of the side clutch lever fulcrum shaft 520 is made to approximately coincide with a direction such as the fore-and-aft direction of the vehicle body (see Figures 1 to 4) or approximately coincide with a direction such as the up-and-down direction (see Figures 5(a) to 5(c)). This specification makes it easy to intuitively understand the appropriate direction for operating the side clutch lever in the left-right direction of the vehicle body, thereby achieving a user-friendly configuration.

[0040] By moving the side clutch lever member 500 so as to abut against the right side clutch lever action member 420, the left side clutch cable locking member 310 is moved, and the left side clutch cable member 210 is pulled. By moving the side clutch lever member 500 so as to abut against the left side clutch lever action member 410, the right side clutch cable locking member 320 is moved, and the right side clutch cable member 220 is pulled.

[0041] The configuration in which the side clutch lever fulcrum shaft 520 is realized by a bearing provided by utilizing existing parts such as the cable stay portion 1104 of the left side clutch cable member 210 and the right side clutch cable member 220 is simple, which facilitates a reduction in the number of parts.

[0042] The side clutch lever member 500 has a side clutch lever operating portion 511 where the side clutch lever is operated, and a side clutch lever abutment portion 512 where the side clutch lever abuts against the left side clutch lever acting member 410 and the right side clutch lever acting member 420, and is moved by being rotated about a side clutch lever fulcrum shaft 520 arranged between the side clutch lever operating portion 511 and the side clutch lever abutment portion 512.

[0043] Since the right side clutch lever acting member 420 and the left side clutch lever acting member 410 move within a plane parallel to the routing plane of the left side clutch cable member 210 and the right side clutch cable member 220, the left side clutch cable member 210 and the right side clutch cable member 220 almost never fall off from the left side clutch cable locking member 310 and the right side clutch cable locking member 320 when the side clutch lever is operated.

[0044] By rotating the side clutch lever operation portion 511 leftward, the side clutch lever abutment portion 512 rotates rightward and is brought into contact with the right side clutch lever action member 420, the left side clutch cable locking member 310 moves, and the left side clutch cable member 210 is pulled. By rotating the side clutch lever operation portion 511 rightward, the side clutch lever abutment portion 512 rotates leftward and is brought into contact with the left side clutch lever action member 410, the right side clutch cable locking member 320 moves, and the right side clutch cable member 220 is pulled.

[0045] The right side clutch lever acting member 420 and the left side clutch lever acting member 410 are operated by a single side clutch lever member 500, which is easy to understand intuitively. One-touch operation is achieved by simply pushing the side clutch lever member 500 in the direction that matches the adjustment direction of the vehicle body travel direction, with a simple configuration.

[0046] When the left side clutch cable member 210 or the right side clutch cable member 220 is pulled in response to the side clutch operation of a walking worker, the movement of the left side clutch cable locking member 310 and the right side clutch cable locking member 320 is prevented by the stopper function.

[0047] The left side clutch cable locking member 310 and the right side clutch cable locking member 320 are fixed in place by a stopper function that limits the range of movement of the cable locking members to the left and right sides of the vehicle body within a predetermined range, so that it is not difficult for a walking operator to operate the side clutch on the steering handle device 20.

[0048] The configuration in which the cable stay portion 1104 also functions as a cable stopper portion, which is achieved by, for example, abutting the left side clutch cable locking member 310 and the right side clutch cable locking member 320 against the cable stay portion 1104, is simple and facilitates a reduction in the number of parts.

[0049] The seedling cup device 40 is a cup device having a seedling cup 41 that receives the seedlings inserted by the on-board worker and planted by the seedling planting device 30.

[0050] The side clutch lever fulcrum shaft 520 is supported by a vertical plate 610 erected near the seedling cup device 40.

[0051] The left side clutch lever acting member 410 and the right side clutch lever acting member 420 are plate members rotatably attached to a horizontal plate 620 fixed to the lower end of a vertical plate 610 at a predetermined angle.

[0052] Guide plates 1103, having an outer diameter larger than that of the arc-shaped plate 1102, are fixed to the lateral plates 620 on both sides of the arc-shaped plate 1102 and function as cable guides in cooperation with the right side clutch lever action member 420 and the left side clutch lever action member 410.

[0053] For example, the arc-shaped plate 1102 of the left side clutch cable locking member 310 is rotatably connected to the left side clutch lever action member 410 and the guide plate 1103 of the left side clutch cable locking member 310, and by arranging the cable using such an arc-shaped plate 1102, it is possible to independently pull only one of the left side clutch cable member 210 and the right side clutch cable member 220.

[0054] By utilizing the arc-shaped plate 1102, the left side clutch cable member 210 and the right side clutch cable member 220 can be smoothly routed along the steering handle device 20, so that the direction of the side clutch cables can be smoothly changed from the main frame 1101 to the grip portion of the steering handle device 20.

[0055] The lower end of the side clutch lever member 500 as the side clutch lever abutment portion 512 is inserted into the space between the plate peripheral portions of the left side clutch lever action member 410 and the right side clutch lever action member 420 which face each other.

[0056] Since the arm thickness of the side clutch lever abutment portion 512 is slightly larger than the spacing of the lever insertion space, the state of the side clutch lever member 500 is stable in the neutral position, and the lever is less likely to wobble.

[0057] (2) Next, the configuration and operation of the vegetable transplanter according to the embodiment of the present invention will be described in more detail with reference mainly to FIGS.

[0058] Here, Figure 6 is a left side view of the vicinity of seedling planting device 30 of a vegetable transplanter according to an embodiment of the present invention, Figure 7 is a right side view (part 1) of the vicinity of seedling planting device 30 of a vegetable transplanter according to an embodiment of the present invention, Figure 8 is a plan view of the vicinity of seedling planting device 30 of a vegetable transplanter according to an embodiment of the present invention, and Figures 9 to 16 are right side views (parts 2 to 9) of the vicinity of seedling planting device 30 of a vegetable transplanter according to an embodiment of the present invention.

[0059] The seedling planting device 30 is a planting device having a seedling planting hopper 31 that can be raised and lowered relative to the vehicle body 10.

[0060] Since the rear mud scraper member 720 is pulled toward the front mud scraper member 710 by the tensile force of the spring 1504, during the period when the seedling planting hopper 31 is lowered from the highest position to the lowest position, the slide pin 1503 is forced in a direction that pushes it upward toward the upper end of the long hole 1506, and the lower end of the rear mud scraper member 720, together with the lower end of the front mud scraper member 710, moves away from the seedling planting hopper 31 (see Figures 9 to 12).

[0061] During the period when the seedling planting hopper 31 is raised from the lowest position to the highest position, the lower end of the rear mud scraper member 720, together with the lower end of the front mud scraper member 710, comes into contact with the seedling planting hopper 31. Therefore, in order to prevent scraper failure due to hopper interference, which is likely to occur due to design errors, etc., the slide pin 1503 slides away from the upper end of the long hole 1506 by resisting the biasing force of the tension spring with the pushing force from the seedling planting hopper 31 (see Figures 13 to 16).

[0062] The front mud scraper member 710 is a scraper member that is swingably attached to the vehicle body 10.

[0063] The scraper arm of the front mud scraper member 710 is driven by a cam 1501 to scrape off mud from the outer front side of the seedling planting hopper 31.

[0064] When the seedling planting hopper 31 is thrust into the ground of the farm field, mud adhering to the outer front side of the seedling planting hopper 31 is scraped downward by the front mud scraper member 710 during the raising process of the seedling planting hopper 31, so that mud is less likely to remain stuck in the front mud scraper member 710.

[0065] The front mud scraper member 710 is firmly pressed against the seedling planting hopper 31 by the biasing force of the spring 1504 or the like, so that the front mud scraper member 710 is guaranteed to adhere closely to the hopper even when the seedling planting hopper 31 is open.

[0066] The front mud scraper pivot point 1507, at which the front mud scraper member 710 is attached to the vehicle body 10, is positioned toward the front of the vehicle body, farther from the seedling planting hopper 31 than the scraper action point in the direction of the hopper pressing operation, and the front mud scraper member 710, which is pressed against the seedling planting hopper 31 as the hopper rises and falls, reliably scrapes off mud adhering to the outer front side of the seedling planting hopper 31 with a large swing stroke.

[0067] The front mud scraper member 710 is positioned near the center of the left-right direction of the vehicle body when viewed in a plan view, and the front mud scraper member 710 is pressed straight against the seedling planting hopper 31, so that mud adhering to the outer front side of the seedling planting hopper 31 is scraped off more reliably.

[0068] The rear mud scraper member 720 is also a scraper member that is swingably attached to the vehicle body 10.

[0069] By driving the scraper arm of the rear mud scraper member 720, mud on the outer rear side of the seedling planting hopper 31 can be scraped off.

[0070] The rear mud scraper pivot fulcrum 1508 at which the rear mud scraper member 720 is attached to the vehicle body 10 is positioned on the outside of the vehicle body in the left-right direction of the vehicle body. Due to this lateral offset of the scraper arm of the rear mud scraper member 720, there is almost no interference with the lifting link operation of the seedling planting hopper 31, and the layout of the front mud scraper pivot fulcrum 1507 described above can be easily realized.

[0071] During at least a portion of the time that the seedling planting hopper 31 is raised, at least one of the front mud scraper member 710 and the rear mud scraper member 720 is pressed against the outer wall surface of the seedling planting hopper 31.

[0072] The mud scraper cam mechanism 800 is a scraper cam mechanism that swings the front mud scraper member 710 in conjunction with the raising and lowering of the seedling planting hopper 31.

[0073] The rotational connection between the scraper arm of the front mud scraper member 710 and the rod 1505 of the mud scraper connection mechanism 900 is made by inserting a welding pin 1502 fixed to the front mud scraper member 710 into a round hole, and the rotational connection between the scraper arm of the rear mud scraper member 720 and the rod 1505 of the mud scraper connection mechanism 900 is made by inserting it into a long hole 1506 of a slide pin 1503 fixed to the rear mud scraper member 720, so that the rear mud scraper member 720 is linked to the front mud scraper member 710.

[0074] The rear mud scraper member 720 may be configured as a straight member, but, for example, it is configured as a bent member so that the slide pin 1503 quickly moves away from the upper end of the long hole 1506 and the lower end of the driven side rear mud scraper member 720 tends to come into contact with the seedling planting hopper 31 earlier than the lower end of the driving side front mud scraper member 710, thereby ensuring independent operation of the front mud scraper member 710 with a large degree of freedom.

[0075] The mud scraper linkage 900 is a scraper linkage that connects the rear mud scraper member 720 to the front mud scraper member 710.

[0076] The spring 1504, which presses the front mud scraper member 710 and the rear mud scraper member 720 against the seedling planting hopper 31 with a tensile force, may be inserted between the scraper arm of the front mud scraper member 710 and the scraper arm of the rear mud scraper member 720, but is inserted between the rod 1505 of the mud scraper connecting mechanism 900 and the scraper arm of the rear mud scraper member 720 so as to suppress the amount of spring movement in response to the swinging of the seedling planting hopper 31 in the fore-and-aft direction of the vehicle body and prevent excessive changes in the hopper pressing load.

[0077] (3) Next, the configuration and operation of the vegetable transplanter according to the embodiment of the present invention will be described in more detail.

[0078] (3A) A specific embodiment relating to the planting sensor configuration of the fully automatic riding vegetable transplanter will be described.

[0079] As shown in Figs. 17(a) to 17(c), which are explanatory diagrams (parts 1 to 3) of the planting sensor configuration of the fully automatic riding vegetable transplanter of the embodiment of the present invention, a first sensor 2101 and a second sensor 2102 on the seedling placement platform, and a communication device 2104 are installed. When the first sensor 2101 stops responding, an alarm is generated and a warning is issued to the monitor unit of the fully automatic riding vegetable transplanter registered in advance or to the user's smartphone. When the second sensor 2102 stops responding, the motor 2103 is controlled in an idle state or a stopped state, and a notification is sent to the monitor unit of the fully automatic riding vegetable transplanter registered in advance or to the user's smartphone. The vehicle body 10 is prevented from moving forward even if the seedlings on the seedling placement platform are gone, and the user can simply stay nearby and come to replace the seedlings when they are gone while performing transplanting activities while riding on a nearby fully automatic riding vegetable transplanter.

[0080] As shown in Fig. 18(a) to 18(c), which are explanatory diagrams (parts 4 to 6) of the planting sensor configuration of the fully automatic riding vegetable transplanter of the embodiment of the vegetable transplanter of the present invention, in comparison with the above-mentioned embodiment, a furrow closing sensor 2105 is installed under the bumper, and when the second sensor 2102 stops responding, the motor 2103 is controlled to be in an idle state or stopped state. The vehicle body 10 is prevented from continuing to move forward even when there are no seedlings on the seedling tray, and in comparison with the above-mentioned embodiment, the user only needs to turn the vehicle body 10 that is nearby and stopped at the corner of the furrow while performing transplanting activities while riding on a nearby fully automatic riding vegetable transplanter.

[0081] As shown in Figs. 19(a) to 19(c), which are explanatory diagrams (parts 7 to 9) of the planting sensor configuration of the fully automatic riding vegetable transplanter of the embodiment of the vegetable transplanter of the present invention, in comparison with the above-mentioned embodiment, a ridge closing sensor 2105 is installed at the connection between the shaft of the vehicle height sensor plate and the vehicle body 10. When the shaft rotates and the ridge closing sensor 2105 is pressed, the vehicle body 10 is controlled to be in an idle state or a stopped state. The vehicle body 10 is prevented from continuing to move forward even when there are no seedlings on the seedling tray, and in comparison with the above-mentioned embodiment, it is possible to make the vehicle body 10 wait in a state where the seedlings are planted right up to the edge of the ridge.

[0082] (3B) A specific embodiment of the motorized planting configuration of the vegetable transplanter will be described.

[0083] As shown in Figs. 20(a) and 20(b), which are explanatory diagrams (parts 1 and 2) of the motorized planting configuration of the vegetable transplanter according to the embodiment of the present invention, the belt is tensioned by utilizing a tension unit 2201 for applying tension from above to the belt connecting the motor and the transmission case. Instead of simply applying tension from below, when torque exceeding a specified value is suddenly applied to the belt, the spring of the tension unit 2201 contracts, causing the belt to slip and creating slack in the belt. When the clutch is turned on, the clutch is suddenly inserted into the rotating body, suppressing the occurrence of the phenomenon that the vehicle body 10 floats up. Even if the clutch is suddenly turned on and the upper surface of the belt is pulled, the tension is applied from the tension unit 2201, creating slack in the belt and making it difficult for the vehicle body 10 to float up.

[0084] (3C) A specific embodiment relating to the configuration of the potato seed tuber side plate edge will be described.

[0085] As shown in Figures 21(a) and 21(b), which are explanatory diagrams (part 1 and part 2) of the edge configuration of the potato seed potato side plate of the vegetable transplanter according to the embodiment of the present invention, the angle of the bottom surface of the seed potato side plate 2301 is higher on the front side but is adjustable in the front-to-rear direction, and the edge of the seed potato side plate 2301 on the rear side, which is the operator's side, is higher. As the potatoes flow toward the operator's hand, the frame fulcrum becomes heavier due to the potatoes flowing toward the operator, which is advantageous from the viewpoint of moment and suppresses the occurrence of member damage.

[0086] The shape of the potato seed potatoes is not the spherical shape of a single seed potato, but, for example, the cut shape of half a seed potato, and the potato seed potatoes are placed on the tray so that the cut surface of such a cut shape comes into contact with the tray surface, so that the potato seed potatoes are unlikely to flow unintentionally due to the stickiness of the cut surface.

[0087] As shown in Fig. 22, which is an explanatory diagram (part 3) of the edge configuration of the potato seed potato side plate of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-mentioned embodiment, a bent portion 2302 is provided facing inward at the upper portion of the edge of the seed potato side plate 2301. Fingers are less likely to be pinched between the container and the edge of the seed potato side plate 2301, and the bent portion 2302 improves safety and strength. Furthermore, the container can be placed once on the edge of the seed potato side plate 2301, which not only makes it easier to insert potatoes but also prevents potatoes from spilling out.

[0088] As shown in Figure 23, which is an explanatory diagram (part 4) of the edge configuration of the potato seed potato side plate of the vegetable transplanter of the embodiment of the present invention, in comparison with the above-mentioned embodiment, by further providing a bridging portion 2303 at the corner between the edges of adjacent seed potato side plates 2301, the strength is further improved and not only can the container be temporarily placed on the bridging portion 2303, but potatoes can also be inserted at an angle into the potato insertion portion, so that steps and bumpers, also known as easy riders, do not become obstacles, making it easier to insert the potatoes.

[0089] (3D) A specific embodiment relating to the configuration of the potato seed tuber side panel opening and closing mechanism will be described.

[0090] As shown in Figures 24(a) and 24(b), which are explanatory diagrams (part 1 and part 2) of the potato seed potato side plate opening and closing mechanism configuration of a vegetable transplanter according to an embodiment of the present invention, a pivot point for pivot pin 2401 is provided at the bottom of the seed potato side plate on the side of the seedling frame, inward from the bottom surface and at a position nearly in contact with the bottom surface, so that the seed potato side plate of the potato insertion stand opens at approximately 90 degrees, and a pin hole into which seedling frame opening and closing lock pin 2402 is inserted is provided at the top. Not only is it easy to insert potatoes because the edge is low and easy to insert containers because the edge is parallel, but it is also easy to replenish potatoes from the adjacent furrow because the edge can be laid down when inserting.

[0091] As shown in FIG. 25, which is an explanatory diagram (part 3) of the configuration of the potato seed potato side panel opening and closing mechanism of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-described embodiment, by raising the pivot point position of the pivot pin 2401 and setting it upward and away from the bottom surface, the container can be opened by 90 degrees or more, so that potatoes and the container can be easily inserted from a low position.

[0092] As shown in Figures 26(a) to 26(c), which are explanatory diagrams (parts 4 to 6) of the configuration of the opening and closing mechanism for the potato seed potato side plate of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-mentioned embodiment, a movable edge member 2403 is provided on the upper surface of the seed potato side plate. The strength is improved, and when the seed potato side plate is laid down and the movable edge member 2403 is tilted from 90 degrees, a container can be hung on the movable edge member 2403, and the container will not escape even if the angle of the movable edge member 2403 is changed.

[0093] As shown in Figures 27(a) and 27(b), which are explanatory diagrams (parts 7 and 8) of the configuration of the opening and closing mechanism for the potato seed potato side plate of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-mentioned embodiment, a plate 2404 with a plurality of holes that rotates with the pivot pin 2401 is provided around the pivot pin fulcrum of the seedling frame on the left and right sides of the vehicle body, and pin holes into which the plate fixing pin 2405 is inserted are provided not only on the plate 2404 but also on the ends of the front and rear seed potato side plates. The plate fixing pin 2405 can be fixed in any pin hole, and the lower end surface of the plate fixing pin 2405 is cut up at an angle so that the plate fixing pin 2405 is less likely to get caught on the plate 2404, and the plate fixing pin 2405 is fixed by a spring 2406 and a frame 2407. Since the container is heavy, the side seed potato panels can be adjusted to any angle, and by placing the container on the helicopter while it is tilted over, the amount of potatoes discharged can be adjusted by adjusting the angle of the helicopter.The side panels of the seedling frame can be lifted with both hands, making it easy to adjust the angle of the seed potato side panels, and when there are few potatoes in the seedling frame, the angle can be increased.The seed potato side panels can also be opened by simply removing the plate fixing pin 2405.

[0094] As shown in Figures 28(a) and 28(b), which are explanatory diagrams (parts 9 and 10) of the potato seed potato side plate opening and closing mechanism of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-mentioned embodiment, plate fixing pins 2405 are provided on the front and rear seed potato side plates, the lower end faces of which are inclined toward the plate rotation direction so as not to get caught on the rotating plate 2404, and handles 2408 are provided near the lower parts of the seed potato side plates adjacent to the lower surface of the seedling frame, making it easier to rotate the side plates. Since a container can be placed on the handles 2408 once, potatoes can be placed in the seedling frame without opening or closing the seed potato side plates.

[0095] As shown in Figures 29(a) and 29(b), which are explanatory diagrams (parts 11 and 12) of the potato seed potato side plate opening and closing mechanism configuration of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-mentioned embodiment, a rod 2409 is extended toward the outside of the seed potato side plate, the rod 2409 is bent midway and extended upward, the open seed potato side plate is supported from below by the end face of the rod 2409 facing upward, a rod return with a jagged shape is provided on the rod 2409, and a rod return holder 2410 is provided on the vehicle body side. The distance from the operator on the left side to the helicopter on the right side is relatively far, but not only can the helicopter angle be adjusted while sitting, but the strength of the helicopter is improved, and since the rod return is on the rod 2409, the seed potato side plate does not open unintentionally.

[0096] (3E) A specific description will be given of aspects relating to the unmanned planting operation configuration of the fully automatic riding vegetable transplanter.

[0097] As shown in Fig. 30, which is an explanatory diagram (part 1) of the unmanned planting operation configuration of a fully automatic riding vegetable transplanter according to an embodiment of the present invention, a first transplanter 2501 ridden by an operator monitors one or more unmanned second transplanters 2502 from behind, and the second transplanter 2502 stops when it runs out of seedlings or reaches the end of a ridge 2504, and the operator riding on the first transplanter 2501 plants the seedlings while replenishing and rotating the second transplanter 2502. A rideable specification for the transplanter, which meets the needs of users who want to ride, greatly improves work efficiency.

[0098] As shown in Figure 31, which is an explanatory diagram (part 2) of the unmanned planting operation configuration of a fully automatic riding vegetable transplanter of an embodiment of the vegetable transplanter of the present invention, in comparison with the above-described embodiment, the third transplanter 2503 is loaded with seedlings and waits at the edge of a ridge 2504, such as a headland, in line with the position of the first transplanter 2501, and when the first transplanter 2501 and the second transplanter 2502 reach the end of the ridge 2504, an operator riding on the first transplanter 2501 replenishes seedlings for the second transplanter 2502, etc.

[0099] As shown in Figures 30 and 31, the third transplanter 2503 is formed by a motor, a computer unit, a panel, a switch, a traveling body on which a seedling frame is mounted, and a seedling carrier attached as necessary. The row spacing, the vehicle number of the first transplanter 2501 to be operated simultaneously, and the number of vehicles of the second transplanter 2502 are input into the panel to calculate the distance that the third transplanter 2503 needs to travel for each round trip. Then, when the switch is pressed, the motor rotates at the required number of revolutions, and the first transplanter 2501 stops at the position where it returns, and the operator riding on the first transplanter 2501 supplies the seedlings, so that by pressing the switch, the motor rotates, making it easy to transport heavy seedlings such as taro seedlings, which are often difficult to transport.

[0100] As shown in Figures 30 and 31, the third transplanter 2503, in comparison with the above-mentioned embodiment, inputs not only the row spacing, the vehicle number of the first transplanter 2501 operated simultaneously, and the number of vehicles of the second transplanter 2502, but also the ridge length and plant spacing into the panel, and more accurately calculates how many round trips are required to cut the seedlings of the first transplanter 2501 and the second transplanter 2502. Then, the second transplanter 2502, etc., which needs to replenish seedlings, stops at the end of the ridge 2504 on which it is traveling, and the operator of the first transplanter 2501 replenishes the seedlings, making it easier to transport heavy seedlings such as taro seedlings, which are often difficult to transport.

[0101] (3F) The configuration of the potato seedling frame will be specifically described.

[0102] As shown in Fig. 32, which is an explanatory diagram (part 1) of the potato seedling frame configuration of the vegetable transplanter according to the embodiment of the present invention, it is possible to omit the sub-seedling frame 2601 on the left side of the vehicle body and install the sub-seedling frame 2601 only on the right side of the vehicle body. Even when it is required to load a sufficient number of potatoes, approximately three containers, it is not easy to reach the potatoes on the left and right sides of the vehicle body, and the sub-seedling frame 2601 is often quite heavy, so by configuring the front of the sub-seedling frame 2601 to be openable, it is easier to check the straightness of the vehicle body and the distance to the edge, improving safety, and the feeling of oppression is reduced by opening the front. Furthermore, by mounting the sub-seedling frame 2601 only on the right side of the vehicle, not only is the vehicle balance improved taking into account the seat of the worker on the left side of the vehicle, but the sub-seedling frame 2601 on the right side of the vehicle is tilted, causing the potatoes to flow toward the center of the vehicle, so that when the worker on the left side of the vehicle moves his / her center of gravity toward the center of the vehicle to direct the remaining potatoes that have shifted to the right side of the vehicle into the chute, it is expected that the vehicle will be stabilized.

[0103] As shown in Fig. 33, which is an explanatory diagram (part 2) of the potato seedling frame configuration of the vegetable transplanter according to the embodiment of the present invention, it is possible to omit the sub-sapling frame 2601 on the right side of the vehicle body and install the sub-sapling frame 2601 only on the left side of the vehicle body. The potatoes are easy to pick because they are right in front of the operator on the left side of the vehicle body, and the edge of the sub-sapling frame 2601 on the left side of the vehicle body also functions as a handrail for the operator on board, which not only improves the operator's sense of security but also promotes weight reduction of the vehicle body by reducing the number of dedicated handrail members.

[0104] As shown in Figures 34(a) and 34(b), which are explanatory diagrams (part 3 and part 4) of the potato seedling frame configuration of the vegetable transplanter according to the embodiment of the present invention, the heights of the front and rear side panels of the sub-seedling frames 2601 attached to the left and right sides of the vehicle are different from each other, and the upper end faces of the side panels on the left and right sides of the vehicle are set to be parallel to the ground by forming an inclination on the bottom surface of the sub-seedling frames 2601. By tilting the sub-seedling frames 2601, the potatoes roll closer to the operator on board, and since the side panels are parallel to the ground, the potatoes can be safely replenished while easily supporting the container placed in a horizontal position on the edge of the side panels.

[0105] As shown in Figures 35(a) and 35(b), which are explanatory diagrams (part 5 and 6) of the potato seed seedling frame configuration of a vegetable transplanter in an embodiment of the present invention, the sub-seedling frame 2601 as a sub-seedling placement table can be opened and closed at an angle of 90 degrees or more, so that the bottom surfaces of the sub-seedling frames 2601 on both sides can be positioned above the bottom surface of the central seedling placement table.By lifting the left sub-seedling frame 2601, forward visibility is ensured while the center of gravity can be moved to the center during transportation, and the sub-seedling frame 2601 can be tilted with the bottom surface always present, so that potatoes can be flowed into the center without any problems.

[0106] As shown in Figures 36(a) and 36(b), which are explanatory diagrams (parts 7 and 8) of the potato seedling frame configuration of the vegetable transplanter according to the embodiment of the present invention, a sub-container holder 2602 is provided below the sub-seedling frame 2601 on the right side of the vehicle body, so that the lower part of the sub-seedling frame 2601 on the right side of the vehicle body can be slid by a sliding part 2603. Then, by making the lower part of the right side sub-seedling frame 2601 slidable so that the potatoes fall naturally after work, the potatoes can be transported at the same time, and therefore the potatoes can be easily stored in a container after work.

[0107] (3G) A specific embodiment relating to the configuration of a simple riding potato shooter will be described.

[0108] As shown in Fig. 37(a) to 37(c), which are explanatory diagrams (parts 1 to 3) of the configuration of a potato shooter, a simple riding transplanter of a vegetable transplanter according to an embodiment of the present invention, in a shooter 2701 that flows supply seed potatoes such as potatoes or taro from a seedling frame to a cup 2702 also called a supply cup, a guide 2703 as a helicopter is provided at the supply port of the cup 2702. Even if the vehicle body 10 is tilted, the seed potatoes are unlikely to fall out of the shooter 2701.

[0109] As shown in Fig. 38(a) to 38(c), which are explanatory diagrams (parts 4 to 6) of the configuration of the potato shooter of the simple riding transplanter of the vegetable transplanter according to the embodiment of the present invention, the bottom shape of the shooter 2701 is matched to the cup outer diameter shape of the first cup 2702 with the cup bottom lid closed, which is located in front of the cup 2702 of the so-called beak supply section. Even if the seed potato supply speed is increased, supply to the first cup 2702 with the cup bottom lid closed can be performed reliably.

[0110] As shown in Fig. 39(a) to 39(c), which are explanatory diagrams (parts 7 to 9) of the simple riding transplanter potato shooter configuration of the vegetable transplanter according to the embodiment of the present invention, in comparison with the above-mentioned embodiment, the edge height of the guide 2703 is changed by forming a high guide portion 2704 and a low guide portion 2705. This not only prevents the seed potatoes from rolling, but also improves the seed potato cup supply rate.

[0111] (3H) The configuration of the potato seedling frame of the simple riding transplanter will be specifically explained.

[0112] As shown in Fig. 40, which is an explanatory diagram (part 1) of the potato seedling frame configuration of a simple riding transplanter vegetable transplanter according to an embodiment of the present invention, a part of the seedling frame bottom 2803 on the riding seat 2802 side is made of an iron plate 2801 with perforations formed therein, thereby improving visibility of the front guide roller position corresponding to the ridge position. Since deviation of the vehicle body 10 from the ridge can be easily confirmed visually, deviation of the vehicle body can be appropriately dealt with by operating the side clutch.

[0113] As shown in Figures 41(a) and 41(b), which are explanatory diagrams (parts 2 and 3) of the potato seedling frame configuration of the simple riding transplanter of the vegetable transplanter according to the embodiment of the present invention, the seedling frame bottom 2803 on the riding seat 2802 side can be freely opened by a hinge 2804. The remaining seed potatoes can be easily collected.

[0114] As shown in Figures 41(a) and 41(b), a structure is adopted in which the hinge 2804 is automatically closed by the biasing force of a hinge mounting spring, and the hinge 2804 is fixed by a knob bolt.
