[0015] Preferred embodiments of the present invention will be described below with reference to the drawings.

[0016] A vegetable transplanter for transplanting vegetable seedlings of an embodiment of the present invention to a field will be described below. In the following description, the side where the steering handle 2 is arranged is the rear, and the side where the engine 3 is mounted on the opposite side is the front. And, the right side toward the front side of the machine body is the right, and the left side is the left.

[0017] As shown in FIGS. 1 and 2, this transplanter includes a traveling vehicle body 1 that enables the machine body to travel forward, a steering handle 2 for walking operation provided at the rear of the traveling vehicle body 1, and a lettuce or green onion in the field. A planting device 20 for planting vegetable seedlings such as (hereinafter collectively referred to as seedlings), and a supply device 30 for supplying seedlings to the planting device 20.

[0018] The traveling vehicle body 1 includes an engine 3, a battery for storing and supplying electric power, left and right drive rear wheels 7L and 7R that are driven to rotate by the driving force from a transmission case that transmits and changes the driving force of the engine 3, and a planting transmission case that transmits the driving force from the transmission case to the planting device 20 and the supply device 30 at a variable speed, and left and right front wheels 9L and 9R that are rotatably supported in front of the left and right drive rear wheels 7L and 7R.

[0019] At both left and right sides of the transmission case, the front parts of left and right long traveling case bodies 11L and 11R are rotatably attached.

[0020] Left and right drive rear wheels 7L and 7R are mounted on left and right axles protruding to the rear side of the left and right traveling case bodies 11L and 11R.

[0021] And, the driving force of the engine 3 is transmitted to the left and right axles via the transmission case, and the left and right drive rear wheels 7L and 7R are driven to rotate.

[0022] In addition, at the attachment portions of the left and right case bodies 11L and 11R to the transmission case, left and right arms extending upward are integrally attached, the upper end portions of each are connected by a balance bar in the left and right direction, and the left and right center of the balance bar is connected to the tip of the piston rod of a lifting cylinder fixed to the machine body.

[0023] When the lifting cylinder is activated and its piston rod extends to the rear of the aircraft, the left and right arms rotate backward, causing the left and right case bodies 11L and 11R to rotate downward, and the aircraft rises. Conversely, when the piston rod of the lifting cylinder moves forward and retracts into the cylinder, the left and right arms rotate forward, causing the left and right case bodies 11L and 11R to rotate upward, and the aircraft descends.

[0024] This lifting cylinder is operated by a ground sensor that makes contact with the ridge surface and operates in response to changes in the vertical distance between the machine and the ridge surface. The ground sensor detects the height of the ridge surface relative to the machine, and the lifting cylinder is configured to operate based on the detection by the ground sensor so that the machine is at a set height relative to the ridge surface.

[0025] Furthermore, the system is configured so that the lifting cylinder is operated by a planting / lifting control device located near the control handle 2, allowing the machine to be manually raised or lowered. This planting / lifting control device is also configured to switch the drive of the planting device 20 and the supply device 30 on and off.

[0026] On the vehicle body 1, a step 23 is provided below the front of the supply device 30 for the worker to place their feet on, and above the step 23 is a worker's seat 24 where the worker who performs the seedling supply operation to replenish the supply device 30 sits.

[0027] Specifically, a worker's seat 24 is positioned facing backward at the center left and right of the machine body, which is in front of the supply device 30.

[0028] As described later, the worker seated in this worker seat 24 sits facing backward towards the front of the supply device 30 and performs seedling replenishment work on the front of the supply device 30, particularly the straight section at the front of the path in which the seedling container 31 moves counterclockwise.

[0029] Furthermore, in step 23, the end on the supply device 30 side is made of wire mesh, allowing each planting device 20 to be seen, so that the seedling planting status of each planting device 20 can be checked and any planting defects can be detected quickly.

[0030] The planting device 20 has a four-row planting configuration with four seedling planting units 21 arranged in the left-right direction of the machine.

[0031] The planting device 20 includes a beak-shaped seedling planting body 21 with its tip pointing downward, an up-and-down movement mechanism that moves the seedling planting body 21 up and down between a position where the lower end of the seedling planting body 21 is above the field surface and a position where it is below the field surface, and an opening and closing mechanism that opens and closes the seedling planting body 21 into a closed state in which the lower end of the beak-shaped seedling planting body 21 is closed to receive seedlings from above and house the seedlings inside, and an open state in which the lower end of the seedling planting body 21 is opened to the left and right to release the seedlings housed inside downward.

[0032] The opening and closing mechanism of the seedling planting body 21 is configured to open downwards when the seedling planting body 21 reaches the lower end position, in conjunction with the operation of the vertical movement mechanism, and to close the lower side of the seedling planting body 21 when the seedling planting body 21 reaches the upper end position, thereby closing it.

[0033] The supply device 30 has a configuration comprising: a plurality of seedling containers 31 that are connected to each other in a loop like an endless chain, each having a cylindrical body that opens at the top and bottom to receive seedlings from above and house the seedlings inside, and a bottom lid that opens and closes the lower opening of the cylindrical body; a movement mechanism that rotates the seedling containers 31 counterclockwise in an elongated oval loop-shaped trajectory that is long from left to right in a plan view of the machine, while passing near the top of the seedling planting body 21; an opening mechanism that opens the bottom lid of the seedling container 31 at a position above the seedling planting body 21 to drop the seedlings housed inside and supply seedlings to the seedling planting body 21; and an auxiliary table 32 that guides the inner circumference of the plurality of seedling containers 31 that are connected in a loop and covers the inner circumference.

[0034] The auxiliary table 32 has a shallow, basin-like structure and can hold a large number of seedlings to be supplied to the seedling container 31.

[0035] The opening mechanism of the supply device 30 is configured such that when the seedling container 31 passes above the seedling planting body 21, the bottom cover is released from the support and rotates downward, opening the bottom cover so that the seedlings inside the seedling container 31 can fall downward. The timing of the opening of the bottom cover of the seedling container 31 is adjusted so that it opens when the seedling planting body 21 rises to directly below the seedling container 31.

[0036] Furthermore, on the right side of the supply device 30, there is a spare tray placement device 33 on which a cell tray T containing seedlings for supplying seedlings to each seedling container 31 of the supply device 30 is placed.

[0037] Specifically, the spare tray placement device 33 is provided with a support pin 34, whose lower part is welded to the right end of the auxiliary table 32 to erect a rotating cylinder 35 at its base, and a frame-like body 37 made of rods, which serves as a tray placement section for placing one cell tray T, is welded and fixed to a support arm 36 extending from the rotating cylinder 35 (see enlarged perspective view of Figure 3).

[0038] The spare tray placement device 33 can be rotated around the support pin 34 to move from a seated replenishment position (a) facing forward of the supply device 30 located to the side of the operator's seat 24, as shown in Figure 1, to a walking replenishment position (b) facing to the right outward of the supply device 30 located to the right outward of the machine, as shown in Figure 2.

[0039] Furthermore, whether the spare tray mounting device 33 is rotated around the support pin 34 to a seated replenishment position (a) facing forward of the supply device 30 located to the side of the operator's seat 24, or to a walking replenishment position (b) facing to the right outside of the supply device 30 located to the right outside of the machine body, the frame-like body 37 on which the cell tray T of the spare tray mounting device 33 is mounted is positioned outside of each seedling container 31 that moves around the supply device 30, and does not interfere with the replenishment of seedlings to each seedling container 31.

[0040] This vegetable transplanter has soil-covering wheels 40 that can freely rotate near the rear left and right sides of the seedling planting area of ​​the seedling planting body 21, for compacting the soil over the seedlings planted by the planting body 21.

[0041] Furthermore, left and right irrigation tanks 42 are provided on the left and right outer positions of step 23 for irrigating seedlings planted in the field by the seedling planting unit 21.

[0042] When the spare tray mounting device 33 is rotated around the support pin 34 to face forward towards the supply device 30 located to the side of the worker's seat 24, the frame-like body 37 on which the cell tray T of the spare tray mounting device 33 is positioned above the right irrigation tank 42.

[0043] To explain the procedure for transplanting seedlings into the field using a vegetable transplanter, the machine is placed in the field and positioned at the beginning of the furrow so that the left and right front wheels 9L and 9R and the left and right drive rear wheels 7L and 7R straddle the furrow.

[0044] The worker removes seedlings from the cell tray T and places them into each seedling container 31, places many more on the auxiliary table 32, and also places the cell tray T full of grown seedlings on the spare tray placing device 33.

[0045] When an operator sits in the operator's seat 24 to perform transplanting work, the spare tray holder 33 is rotated around the support pin 34 to face forward towards the supply device 30 located to the side of the operator's seat 24, in the seated replenishment position (a). When the operator sits in the operator's seat 24, starts the engine 3, operates the throttle, and engages the main clutch lever, the machine moves forward, and the seedling container 31 of the supply device 30 moves in a circular motion so that it passes above the seedling planting body 21. When the seedling planting body 21, which is tracing an up-and-down trajectory, reaches the upper position, the bottom of the seedling container 31 opens, dropping the seedlings contained inside and supplying them into the seedling planting body 21. When the seedling planting body 21 reaches the lower descent end position, the lower side of the seedling planting body 21 opens to the left and right to plant the seedlings in the field, and the soil covering wheel 40 compacts and covers both sides of the planted seedlings.

[0046] The worker, seated in the worker's seat 24, takes seedlings placed on the auxiliary table 32 and places them sequentially into the empty seedling containers 31 that move in a circular manner. Additionally, seedlings are taken from the cell trays T placed on the spare tray placement device 33 located to the side of the worker's seat 24 and placed sequentially into the seedling containers 31, thereby supplying seedlings efficiently.

[0047] Furthermore, when an operator walks along the right side of the machine in accordance with its movement while performing transplanting work, the spare tray mounting device 33 is rotated around the support pin 34 to the walking supply position (b) facing the right outer side of the supply device 30 located on the right outer side of the machine. When the engine 3 is started and the throttle is operated and the main clutch lever is engaged, the machine moves forward and the seedling container 31 of the supply device 30 moves in a circle so that it passes above the seedling planting body 21. When the seedling planting body 21, which is tracing an up-and-down trajectory, reaches the upper position, the bottom of the seedling container 31 opens and the seedlings contained inside fall out and are supplied into the seedling planting body 21. When the seedling planting body 21 reaches the lower descent end position, the lower side of the seedling planting body 21 opens to the left and right to plant the seedlings in the field, and the soil covering wheel 40 covers both sides of the planted seedlings with soil.

[0048] A worker walking along the right side of the machine in accordance with its movement takes seedlings placed on the auxiliary table 32 and sequentially places them into each empty seedling container 31 as it moves in a circular path. Additionally, seedlings are taken from the cell tray T placed on the spare tray placement device 33 located in front of the worker and sequentially placed into each seedling container 31, thereby supplying seedlings efficiently.

[0049] Therefore, when performing transplanting work while seated in the worker's seat 24, the spare tray holder 33 is rotated around the support pin 34 to face forward of the supply device 30 located to the side of the worker's seat 24, in a seated replenishment position (a). When performing transplanting work while walking along the right side of the machine in accordance with the machine's movement, the spare tray holder 33 is rotated around the support pin 34 to face outward to the right of the supply device 30 located on the right outer side of the machine, in a walking replenishment position (b). This allows for efficient seedling transplanting work with good workability tailored to the work situation.

[0050] Furthermore, in addition to placing seedlings on the auxiliary table 32, the cell tray T can also be placed on the spare tray placement device 33, which reduces the number of times the machine needs to be stopped to load seedlings onto the machine, thereby improving work efficiency.

[0051] Furthermore, the spare tray placement device 33 is positioned with a gentle incline so that the tip is higher than the base, and the cell tray T placed on the spare tray placement device 33 is placed with the tip higher, making it easy for the worker to remove seedlings from the cell tray T and improving work efficiency.

[0052] Furthermore, by rotating the spare tray mounting device 33 around the support pin 34 and positioning it on the auxiliary table 32 to create a stored state for the aircraft, it does not get in the way when moving on the road, loading it onto a truck, or storing the aircraft in a barn or similar location.

[0053] Figures 4 to 6 show a second embodiment of the spare tray placement device 33.

[0054] In other words, the spare tray placement device 33 of the second embodiment has a drive shaft 51 that moves each seedling container 31, which is provided at the right end of the support frame 50 on the bottom surface of the supply device 30, around a base boss 52 that is rotatably attached to the drive shaft 51 (a washer 53a and a cotter pin 53b are provided on the lower side of the boss 52 to prevent it from falling), and a frame-like body 37 made of a rod that places one cell tray T on the upper end of an L-shaped arm 54 that extends outward from the boss 52 and further upward from the supply device 30.

[0055] The frame-shaped body 37 is mounted by rotatably fitting a cylindrical 37a, which serves as a rotating boss and is welded to the frame-shaped body 37, onto an outwardly extending support pin 55a provided at the upper end of the arm 54. The frame-shaped body 37 is held in an inclined state in which rotation is restricted by either of the outwardly extending rotation restricting pins 55b or 55c provided on both sides of the support pin 55a at the upper end of the arm 54.

[0056] Furthermore, since the rotation restricting pin 55c is positioned lower than the rotation restricting pin 55b, restricting rotation with the rotation restricting pin 55c results in a larger and steeper inclination angle of the frame-like body 37.

[0057] The spare tray placement device 33 can be rotated around the drive shaft 51, allowing it to rotate 90 degrees from a seated replenishment position (a) facing forward of the supply device 30 located to the side of the operator's seat 24, as shown in Figure 4, to a walking replenishment position (b) facing to the right outward of the supply device 30 located to the right outward of the machine.

[0058] Furthermore, near the drive shaft 51 on which the boss 52 of the spare tray mounting device 33 is rotatably mounted, two rotation restricting plates 50a and 50b are provided, with their bases welded and fixed to the support frame 50. When the spare tray mounting device 33 is rotated around the drive shaft 51 to the seated replenishment position (a) facing forward of the supply device 30 located to the side of the worker's seat 24, the arm 54 comes into contact with the rotation restricting plate 50a and its rotation is restricted. When the device is moved to the walking replenishment position (b) facing to the right outside of the supply device 30 located to the right outside of the machine body, the arm 54 comes into contact with the rotation restricting plate 50b and its rotation is restricted.

[0059] In other words, the rotation of the spare tray placement device 33 is limited to 90 degrees from the seated replenishment position (a) to the walking replenishment position (b).

[0060] Furthermore, there is no stopper between the seated replenishment position (a) and the walking replenishment position (b), allowing the unit to rotate to any angle even during operation.

[0061] Therefore, the spare tray placement device 33 is stable at any position, but by setting a limit range, it does not interfere with work or compromise safety.

[0062] Furthermore, the arm 54 of the spare tray mounting device 33 is bent into an L-shape so as not to interfere with the supply device 30, and moreover, it rotates at a position above the irrigation tank 42 so as not to interfere with the irrigation tank 42.

[0063] When an operator is seated in the operator's seat 24 and performing transplanting work, the spare tray placement device 33 is rotated around the drive shaft 51 to face forward of the supply device 30 located to the side of the operator's seat 24, in the seated replenishment position (a). The frame-shaped body 37 is then rotated around the support pin 55a to a steeply inclined state where rotation is restricted by the rotation restricting pin 55c. As a result, the frame-shaped body 37 is steeply inclined towards the operator's seat 24, and the cell tray T is also steeply inclined towards the operator's seat 24, allowing the operator seated in the operator's seat 24 to easily remove seedlings from the cell tray T.

[0064] Furthermore, when an operator walks along the right side of the machine in accordance with its movement while performing transplanting work, the spare tray placement device 33 is rotated around the drive shaft 51 to the walking supply position (b) facing the right outer side of the supply device 30 located on the right outer side of the machine, and the frame-shaped body 37 is rotated around the support pin 55a to a gently sloping state where rotation is restricted by the rotation restricting pin 55b. As a result, the frame-shaped body 37 is gently sloping toward the operator, and the cell tray T is also gently sloping toward the operator, so that the operator can easily remove seedlings from the cell tray T.

[0065] Furthermore, as shown in Figure 6, the cylinder 37a, which rotatably attaches the frame-shaped body 37 to the support pin 55a, is positioned offset from the center of the frame-shaped body 37 towards the worker's seat 24. When the seated replenishment position (a) is set to a steep incline, the cylinder 37a is closer to the center of the frame-shaped body 37 than when the walking replenishment position (b) is set to a gentle incline. Therefore, the frame-shaped body 37 is stable at an angle that is easy to use in both the seated replenishment position (a) and the walking replenishment position (b), making it user-friendly.

[0066] Furthermore, since the length of the frame-like body 37 is set to be longer than the length of the cell tray T, when rotating the frame-like body 37 around the support pin 55a, placing the cell tray T on the side to be rotated makes it easier to rotate the frame-like body 37.

[0067] Furthermore, the rotation restricting pin 55b is detachably provided on the upper end of the arm 54. By rotating the spare tray mounting device 33 around the drive shaft 51 to the seating replenishment position (a), and removing the rotation restricting pin 55b, the frame-like body 37 can be rotated outward around the support pin 55a to stand vertically and fold up, fitting within the left-right width dimension of the machine.

[0068] Figure 7 shows another embodiment of the supply device 30.

[0069] In other words, the bottom surface 32a of the auxiliary table 32 of the supply device 30 is sloped downwards toward the back when viewed from the perspective of a worker seated in the worker's seat 24, and seedlings placed on the auxiliary table 32 accumulate toward the back (rear).

[0070] Furthermore, the side wall 32b of the auxiliary table 32 does not have a side (front side) on the side where the worker is seated in the worker's seat 24, and the front side of the inclined bottom surface 32a is at the same height as the upper end of the seedling container 31.

[0071] Therefore, the worker does not need to lift the seedlings from the back, but can slide them into the seedling container 31 by sliding them along the bottom surface 32a.

[0072] Furthermore, the left and right curved sections of the auxiliary table 32 have side walls 32b, allowing seedlings to be stored in the curved sections of the left and right sides of the auxiliary table 32 as well.

[0073] Figure 8 shows another embodiment of the auxiliary table 32.

[0074] Specifically, the auxiliary table 32 is divided into a central table 32c made of metal (iron) and left and right side tables 32s made of synthetic resin, and is detachably constructed by engaging the engaging claws 60 at the ends of the left and right side tables 32s with the fitting holes 61 at the left and right ends of the central table 32c.

[0075] Therefore, where multiple auxiliary tables 32 are generated depending on the crop and specifications, a shared design can be easily achieved by sharing the left and right side tables 32s and creating only a new central table 32c.

[0076] Furthermore, since the left and right side tables 32s are detachable, accumulated debris on the auxiliary table 32 can be easily cleaned.

[0077] Figure 9 shows another embodiment of the planting device 20.

[0078] Specifically, the ends of two cables 46, 46 are connected to the left and right vertical rods 45a, 45a of the compaction wheel frame 45, which supports the soil compaction wheel 40 so that it can rotate freely. The two cables 46, 46 are assembled so that their centers bulge towards the center of the compaction wheel frame 45, forming a hole 47 at the intersection through which the lower end of the seedling planting body 21 of the planting device 20 is inserted.

[0079] As the lower end of the seedling planting body 21 closes and enters the hole 47 during the descending process to plant seedlings in the field, the lower end of the seedling planting body 21 opens to the left and right, planting seedlings in the field and ascending, and the outer surface of the seedling planting body 21 is rubbed by the cables 46, 46, causing any attached mud to be removed.

[0080] In other words, the two cables 46, 46 function as scrapers to remove mud and soil adhering to the outer surface of the seedling planting body 21.

[0081] Furthermore, the two cables 46, 46 are connected by attaching both ends to the left and right vertical rods 45a, 45a with screws 46a, 46a, and the length of the cables 46, 46 can be adjusted so that they are taut when the seedling planting body 21 is opened to the left and right.
