[0011] A transplanter 1 according to an embodiment will be described with reference to Figs. 1 to 3. Fig. 1 is a perspective view of the transplanter 1 according to an embodiment, seen obliquely from behind. Fig. 2 is a plan view of the transplanter 1 according to an embodiment. Fig. 3 is a rear view of the transplanter 1 according to an embodiment. Note that a part of the transplanter 1 is omitted in Figs. 1 to 3.

[0012] The transplanter 1 is driven manually or automatically on a running body 2 having a pair of left and right front wheels 3 and a pair of rear wheels 4, and plants transplants using a planting device 5 having a planting tool 5a.

[0013] A transmission case 6 (transmission) is provided at the front of the traveling vehicle body 2, and an engine is provided in front of the transmission case 6. Axle covers 7 that cover the axles that transmit driving force to the rear wheels 4 are respectively connected to the rear of the vehicle body on both the left and right sides of the transmission case 6. A traveling transmission case 8 that transmits driving force to the rear wheels 4 is rotatably attached to the outer end of the axle cover 7.

[0014] The traveling vehicle body 2 is provided with a transmission case that branches and supplies driving force from the transmission case 6 to the planting device 5 and the supplying device 10. In other words, the planting device 5 and the supplying device 10 are operated by the driving force transmitted from the engine. At least one of the planting device 5 and the supplying device 10 may be operated by an electric motor.

[0015] A steering handle 11 for manual steering is provided at the rear of the traveling vehicle body 2. A throttle lever for increasing or decreasing the engine output is provided on the steering handle 11. A vehicle height adjustment lever, a main clutch lever, a main gear shift lever, an engine switch, etc. are provided between the left and right sides of the steering handle 11.

[0016] The vehicle height adjustment lever is a lever that adjusts the vehicle height of the traveling body 2. The main clutch lever is a lever that switches on and off the transmission of driving force to the left and right traveling transmission cases 8 and the transmission case. The main speed change lever is a lever that switches the traveling transmission of the traveling body 2 between travel speed, planting work, traveling neutral, and reverse. The engine switch is a switch that switches whether the engine can be started and also performs the stop operation.

[0017] The traveling vehicle body 2 is provided with auxiliary wheels 12. The auxiliary wheels 12 are attached to the axles of the rear wheels 4 via mounting fixtures 13.

[0018] An auxiliary step 15 is attached to the traveling body 2. The auxiliary step 15 is provided above the auxiliary wheels 12. The auxiliary step 15 is attached to the rear wheels 4. The auxiliary step 15 is attached to the axle of the rear wheels 4. The auxiliary step 15 is attached so that its height is adjustable relative to the frame 2a of the traveling body 2. A substantially L-shaped mounting frame 16 is attached to the auxiliary step 15. The mounting frame 16 is attached to the frame 2a of the traveling body 2 via a first adjustment mechanism 18.

[0019] The first adjustment mechanism 18 is capable of adjusting the height of the auxiliary step 15 and the seat 20 relative to the frame 2a. The first adjustment mechanism 18 includes a connection portion 18a, a cylindrical portion 18b, and a fixing pin. The connection portion 18a is fixed to the upper end of the mounting frame 16. The connection portion 18a is provided so as to extend from the upper end of the mounting frame 16 toward the frame 2a. The tip of the connection portion 18a on the frame 2a side is connected to the cylindrical portion 18b.

[0020] The frame 2a is inserted into the cylindrical portion 18b. The cylindrical portion 18b is formed with a hole 18c into which the fixing pin is inserted. The frame 2a is formed with a plurality of holes 2b arranged in the vertical direction. The fixing pin is inserted into the hole 18c formed in the cylindrical portion 18b and the hole 2b formed in the frame 2a to connect the cylindrical portion 18b and the frame 2a. The vertical position of the cylindrical portion 18b relative to the frame 2a is changed, and the position of the hole 2b of the frame 2a into which the fixing pin is inserted is changed, so that the position of the cylindrical portion 18b relative to the frame 2a is changed. That is, the height of the mounting frame 16 relative to the frame 2a, that is, the height of the auxiliary step 15 is changed by changing the position of the hole 2b of the frame 2a into which the fixing pin is inserted. In this way, the height of the mounting frame 16 relative to the frame 2a is adjusted, so that the height of the auxiliary step 15 is adjusted.

[0021] The method of adjusting the height of the auxiliary step 15 by the first adjustment mechanism 18 is not limited to the above-mentioned method using a fixing pin. For example, the height of the auxiliary step 15 may be adjustable by a crank bolt or the like.

[0022] The traveling vehicle body 2 is provided with a seat 20. The seat 20 is provided above the auxiliary step 15. The seat 20 is attached to the connection portion 18a of the first adjustment mechanism 18 via the second adjustment mechanism 21.

[0023] The second adjustment mechanism 21 is capable of adjusting the height of the seat 20 and the rotational position of the seat 20. The second adjustment mechanism 21 includes a mounting portion 21a, a cylindrical portion 21b, and a fixing pin.

[0024] The mounting portion 21a is connected to the connection portion 18a so as to be rotatable around an axis along the vertical direction. That is, the seat 20 is rotatable around an axis along the vertical direction relative to the connection portion 18a. The mounting portion 21a may be connected to the mounting frame 16 so as to be rotatable around an axis along the vertical direction. The mounting portion 21a extends from the connection portion 18a toward the outside of the traveling vehicle body 2. The outer tip of the mounting portion 21a is connected to the cylindrical portion 21b. The mounting portion 21a is provided with a stopper 22 capable of restricting the rotation of the mounting portion 21a relative to the connection portion 18a.

[0025] The mounting rod 20a extending downward from the seat 20 is inserted into the cylindrical portion 21b. The cylindrical portion 21b is formed with a hole 21c into which the fixing pin is inserted. The mounting rod 20a is formed with a plurality of holes 20b arranged vertically. The fixing pin is inserted into the hole 21c formed in the cylindrical portion 21b and the hole 20b formed in the mounting rod 20a to connect the cylindrical portion 21b and the mounting rod 20a. The vertical position of the mounting rod 20a relative to the cylindrical portion 21b is changed, and the position of the hole 20b of the mounting rod 20a into which the fixing pin is inserted is changed, so that the position of the mounting rod 20a relative to the cylindrical portion 21b is changed. That is, the height of the mounting rod 20a relative to the cylindrical portion 21b, i.e., the height of the seat 20, is changed by changing the position of the hole 20b of the mounting rod 20a into which the fixing pin is inserted. In this way, the height of the mounting rod 20a relative to the cylindrical portion 21b is adjusted, so that the height of the seat 20 is adjusted. The second adjustment mechanism 21 can adjust the height of the seat 20 relative to the auxiliary step 15.

[0026] The method of adjusting the height of the seat 20 by the second adjustment mechanism 21 is not limited to the above-mentioned method using a fixing pin. For example, the height of the seat 20 may be adjustable by a crank bolt or the like.

[0027] When the height of the auxiliary step 15 is adjusted by the first adjustment mechanism 18, the height of the seat 20 is adjusted together with the height adjustment of the auxiliary step 15. Furthermore, the height of the seat 20 relative to the auxiliary step 15 is adjusted by the second adjustment mechanism 21. That is, the height of the seat 20 can be adjusted by the first adjustment mechanism 18 and the second adjustment mechanism 21.

[0028] The intervals between the holes 2b formed in the frame 2a and the intervals between the holes 20b formed in the mounting rod 20a may be different from each other, thereby allowing fine adjustment of the height of the seat 20.

[0029] When an operator ascends or descends to the auxiliary step 15 and sits on or leaves the seat 20, the seat 20 is rotated backward as shown in Fig. 4. Fig. 4 is a diagram showing a state in which the seat 20 has been rotated backward.

[0030] Furthermore, when the worker performs the task of putting the transplant into the supply cup 31 described below, the seat 20 is rotated forward as shown in Fig. 5. Fig. 5 is a diagram showing a state in which the seat 20 has been rotated forward. For example, when the worker performs the task of putting the transplant into the supply cup 31, the worker can rotate the seat 20 so that it faces the supply cup 31.

[0031] A brake operation device 25 and an accelerator operation device 26 are provided on the auxiliary step 15. The brake operation device 25 and the accelerator operation device 26 are provided on the auxiliary step 15 so that an operator seated on the seat 20 can operate them with his / her feet.

[0032] The brake operation device 25 is, for example, a brake pedal provided on the auxiliary step 15. For example, a spring is provided between the brake pedal and the auxiliary step 15. The spring is provided so as to urge the brake pedal upward. In addition, a cable is attached to the brake pedal, and when the brake pedal is depressed by an operator, the brake pedal rotates downward and the cable is pulled, thereby activating the brake device and decelerating the traveling vehicle body 2.

[0033] The accelerator operation device 26 is, for example, an accelerator pedal provided on the auxiliary step 15. The accelerator pedal has a structure similar to that of a brake pedal, and when the accelerator pedal is depressed by an operator, the accelerator pedal rotates downward, and the engine speed increases.

[0034] The planting tool 5a is raised and lowered by the planting tool lifting mechanism to perform the planting work of transplants. The planting tool lifting mechanism uses the driving force transmitted from the engine to intermittently raise and lower the planting tool 5a. The planting tool 5a is formed in a beak shape with the tip pointing downward. The upper end of the planting tool 5a is open. With the tip of the planting tool 5a closed, transplants are placed into the planting tool 5a through the opening at the upper end via the supply cup 31. When the planting tool 5a is lowered by the planting tool lifting mechanism, the tip opens and the transplant is planted in the field.

[0035] The supply device 10 is provided above the planting tool 5a. The supply device 10 includes a supply cup stand 30. The supply cup stand 30 is formed in a substantially circular shape when viewed from above. A plurality of supply cups 31 are provided on the supply cup stand 30. The plurality of supply cups 31 are arranged along the circumferential direction of the supply cup stand 30. The supply cup 31 is formed in a cylindrical shape with openings at the top and bottom ends, and includes a bottom lid that opens and closes the opening on the lower side.

[0036] The supply cup base 30 rotates by the driving force transmitted from the transmission case 6. The supply cup base 30 rotates counterclockwise. The supply device 10 opens the bottom cover of the supply cup 31, which is now above the planting tool 5a, and drops the transplants contained in the supply cup 31 into the planting tool 5a.

[0037] As shown in Figs. 6 to 8, the transplanter 1 further includes a mounting table 40 and a supply chute 41. Fig. 6 is a perspective view illustrating the mounting table 40, the supply chute 41, and the supply device 10. Note that Fig. 6 omits a portion of the transplanter 1. Fig. 7 is an enlarged perspective view of the vicinity of the supply chute 41. Fig. 8 is a plan view of the vicinity of the supply chute 41.

[0038] The mounting table 40 is supported by a mounting table frame 2d (see FIG. 1, etc.) provided on the traveling body 2. The mounting table 40 is provided on the front side of the traveling body 2. The mounting table 40 is provided above the engine. The transplant is placed on the mounting table 40. The mounting table 40 is provided with a side wall 40a that prevents the transplant from falling off the mounting table 40.

[0039] The supply chute 41 is provided behind the mounting table 40. The supply chute 41 is provided to extend from the mounting table 40 toward the supply cup table 30. The supply chute 41 is supported by a support pin provided in the center of the supply cup table 30. The supply chute 41 has a bottom 42 and a side wall 43.

[0040] The bottom 42 is formed to extend from the mounting table 40 to the vicinity of the rotation axis (center) of the supply device 10. The bottom 42 includes an arc portion 42a formed at the tip on the supply device 10 side. The arc portion 42a is formed in an arc shape. The arc portion 42a is formed, for example, at a position that contacts the edge of the supply cup 31 on the rotation axis side of the supply device 10 in a top view. In addition, a notch 42b is formed in the bottom 42 on the seat 20 side.

[0041] The cutout 42b is formed to be recessed along the arrangement direction of the supply cup 31 of the supply device 10 in a top view. The cutout 42b is formed in an arc shape. The cutout 42b is provided above the position where the bottom lid of the supply cup 31 is closed. The formation of the cutout 42b makes it easier for an operator seated on the seat 20 to put the transplant from the supply chute 41 into the supply cup 31.

[0042] The side wall 43 is formed to extend upward from the bottom portion 42. The side wall 43 is not formed on the arc portion 42a on the seat 20 side. This makes it easier for the operator to put the transplant into the supply cup 31 from the arc portion 42a.

[0043] The side wall 43 includes a left side wall 43a and a right side wall 43b. The left side wall 43a is formed from the mounting table 40 to the vicinity of the notch 42b. The left side wall 43a is formed so as to extend in the tangential direction of the notch 42b. The height of the left side wall 43a decreases from the mounting table 40 toward the notch 42b.

[0044] The right side wall 43b is formed from the mounting table 40 to the vicinity of the arc portion 42a. For example, the right side wall 43b is formed to the end of the arc portion 42a. The right side wall 43b is formed to the bottom portion 42, which is a portion that hides the supply cup 31 in a top view when the supply cup table 30 rotates. This prevents the operator from having his / her fingers pinched between the supply cup table 30 and the supply chute 41. The height of the right side wall 43b decreases from the mounting table 40 toward the arc portion 42a.

[0045] When placing transplants in the supply cup 31 , the worker can place the transplants in the supply cup 31 while sitting on the seat 20 provided above the auxiliary step 15 .

[0046] The transplanter 1 according to the embodiment includes a traveling body 2, a planting device 5, an auxiliary step 15, a seat 20, a first adjustment mechanism 18, a second adjustment mechanism 21, a brake operation device 25, and an accelerator operation device 26. The planting device 5 is provided on the traveling body 2, and plants the transplants placed in the supply cup 31 in the field. The auxiliary step 15 is attached to the rear wheel 4 of the traveling body 2. The seat 20 is provided above the auxiliary step 15 and is rotatable around an axis along the vertical direction. The first adjustment mechanism 18 and the second adjustment mechanism 21 are capable of adjusting at least one of the height of the seat 20 and the rotation position of the seat 20. The brake operation device 25 can be operated by an operator seated on the seat 20. The accelerator operation device 26 can be operated by an operator seated on the seat 20.

[0047] This allows the operator to place the transplant in the supply cup 31 while seated on the seat 20. For example, when the operator works alone, the operator can place the transplant in the supply cup 31 while seated on the seat 20. Therefore, the transplanter 1 can improve the safety of the operator.

[0048] In the transplanter 1, the seat 20 can be rotated around an axis along the vertical direction, so that when an operator sits on or leaves the seat 20, the operator can easily sit on or leave the seat 20 by rotating the seat 20. Therefore, the transplanter 1 can improve the safety of the operator when the operator sits on or leaves the seat 20.

[0049] The operator can adjust the speed of the transplanter 1 while seated on the seat 20 by operating the brake operating device 25 and the accelerator operating device 26 provided on the auxiliary step 15. Therefore, the transplanter 1 can improve the operability by the operator. In addition, the transplanter 1 can improve the safety of the operator who works while seated.

[0050] In addition, by providing a seat 20 on the transplanter 1, for example, when multiple transplanters 1 are used to transplant crops into a field, an operator sitting on the seat 20 of the rear transplanter 1 can discover poor transplanting caused by the front transplanter 1.

[0051] The transplanter 1 includes a mounting table 40, a supply chute 41, and a supply cup table 30. The mounting table 40 is used to mount transplants. The supply chute 41 extends from the mounting table 40 toward the supply cup 31. The supply cup table 30 has a plurality of supply cups 31 arranged along the circumferential direction and rotates along the circumferential direction. The supply chute 41 includes a bottom 42 and a side wall 43. The side wall 43 extends upward from the bottom 42. The bottom 42 includes an arc portion 42a formed at the tip on the supply cup table 30 side and formed in an arc shape so as to contact the edge of the supply cup 31 in a top view. The side wall 43 is not formed on the arc portion 42a on the seat 20 side.

[0052] This allows the operator to easily place the transplant, which has been moved from the placement table 40 to the supply cup table 30 side by the supply chute 41, into the supply cup 31 from the arc portion 42a.

[0053] As shown in Fig. 9, the supply chute 41 may have a first side wall 43c and a second side wall 43d formed on the right side wall 43b. Fig. 9 is a plan view illustrating the supply chute 41 of the transplanter 1 according to a modified example. The first side wall 43c is provided along the front-rear direction of the traveling body 2. The second side wall 43d is provided along the left-right direction of the traveling body 2. The second side wall 43d is connected to the rear end of the first side wall 43c. The second side wall 43d is provided to pass through the rotation center axis P of the supply cup stand 30.

[0054] This allows a large number of transplants to be loaded onto the supply chute 41. Therefore, the number of times that the worker moves the transplants from the placement table 40 to the supply chute 41 can be reduced.

[0055] The supply chute 41 may have a viewing section 44 on the bottom 42 as shown in Fig. 10. Fig. 10 is a plan view showing a part of the transplanter 1 according to a modified example. The viewing section 44 is provided so that the operator can view the supply cup 31 below the bottom 42. The viewing section 44 is formed, for example, in a net shape.

[0056] This allows an operator to check the state of supply cup 31 located below bottom portion 42 using visual inspection portion 44 .

[0057] The supply chute 41 may be composed of an upper chute and a lower chute. The supply chute 41 may be provided rotatably. For example, the opening of the upper chute may be blocked by rotating the lower chute upward. The visual observation unit 44 may be provided in the upper chute and the lower chute.

[0058] The mounting table 40 may be composed of a central table 45 and end tables 46 provided on the left and right of the central table 45. The angle of the end tables 46 can be adjusted with respect to the central table 45. For example, as shown in FIG. 11, a hole 46b is formed in a fixing plate 46a provided on the end table 46, and a plurality of holes 45b are formed in a fixing plate 45a provided on the central table 45. FIG. 11 is a view of a part of the mounting table 40 according to a modified example, seen from diagonally below. The mounting table 40 is capable of changing the angle of the end tables 46 with respect to the central table 45 by inserting fixing pins into the holes 46b formed in the fixing plate 46a of the end table 46 and the holes 45b formed in the fixing plate 45a of the central table 45.

[0059] As a result, the transplanter 1 can move transplanted plants from the end table 46 to the central table 45 by, for example, increasing the angle of the end table 46. Therefore, an operator can easily move the transplants gathered on the central table 45 by moving them to the supply chute 41. In addition, for example, when loading the transplanter 1 onto a truck, the transplanter 1 can be transported safely by tying a rope through the hole 45b.

[0060] In addition, holes 45b are also formed on the outer side of the fixing plate 45a of the central stand 45. This allows the transplanter 1 to tilt the end stand 46 toward the central stand 45, and prevents the end stand 46 from coming into contact with obstacles such as tree branches when traveling along the edge of a field, for example.

[0061] The transplanter 1 may have a sub-mount on the right chain case so as to sandwich the chain case. The rear and right side walls of the sub-mount can be opened, closed, and locked.

[0062] As shown in Fig. 12 and Fig. 13, the mounting table 40 may include a plurality of rails 50, a gathering portion 51, a rod 52, and a spring 53. Fig. 12 is a perspective view showing a state in which the mounting table according to the modified example is provided on the traveling vehicle body 2. Fig. 13 is a plan view showing an outline of the mounting table 40 according to the modified example.

[0063] The rails 50 are provided along the front-rear direction of the traveling vehicle body 2. For example, the rails 50 are provided at both ends in the left-right direction. The gathering portion 51 is provided along the left-right direction.

[0064] The gathering portion 51 is formed, for example, in a rod shape. The gathering portion 51 is movable along the rail 50. That is, the gathering portion 51 is supported by the rail 50 so as to be movable in the front-rear direction along the rail 50. The gathering portion 51 is biased rearward by a spring 53.

[0065] The rod 52 is attached to the gathering portion 51 and is provided so as to extend rearward from the gathering portion 51. The rod 52 is provided so as to be operable by an operator.

[0066] This allows the operator to move the gathering part 51 rearward by operating the rod 52, thereby moving the transplants rearward. Furthermore, the transplanter 1 can push the gathering part 51 rearward by the spring 53, for example, when there are few transplants, thereby improving workability. The mounting table 40 may be provided with a locking mechanism for fixing the gathering part 51.

[0067] The mounting table 40 may be configured without the spring 53 (see FIG. 13) as shown in Fig. 14. Fig. 14 is a plan view showing an outline of the mounting table 40 according to a modified example.

[0068] The gathering portion 51 may be provided so as to be movable in the left-right direction as shown in Fig. 15. Fig. 15 is a plan view showing an outline of the mounting platform 40 according to a modified example. In this case, the multiple rails 50 are provided in the left-right direction of the traveling vehicle body 2. The gathering portion 51 is provided so as to extend in the front-rear direction. The gathering portion 51 is biased leftward by a spring 53. The rod 52 is provided so as to extend from the gathering portion 51 toward the seat 20. The mounting platform 40 may be configured so as not to include the spring 53.

[0069] As shown in Fig. 16, the mounting table 40 may have a plurality of rails 50a, 50b provided along the front-rear and left-right directions of the traveling body 2, and may be provided with two gathering portions 51a, 51b and two rods 52a, 52b. Fig. 16 is a plan view showing an outline of the mounting table 40 according to a modified example.

[0070] As shown in Fig. 17, the mounting table 40 may be supported on the stay 2e of the traveling vehicle body 2 via a spring 55. Fig. 17 is a side view showing an outline of the mounting table 40 according to a modified example. The mounting table 40 is supported so as to be rotatable about a rotation axis on the rear side. The spring 55 is provided so as to bias the mounting table 40 upward.

[0071] As a result, when the amount of transplants placed on the mounting table 40 decreases, the mounting table 40 is inclined by the spring so that the front side becomes higher. Therefore, the transplants on the mounting table 40 move backward. Therefore, the transplanter 1 can move the transplants backward.

[0072] The mounting table 40 may be further divided into two by a dividing line along the front-rear direction, and the outer side of each mounting table 40 may be supported by a stay in a state in which it is biased upward by a spring. Each mounting table 40 is supported so as to be rotatable about a rotation axis on the central side in the left-right direction.

[0073] Thereby, the transplanter 1 can move the transplant toward the center of the mounting table 40 by rotating each mounting table 40 by the spring.

[0074] The mounting table 40 may be rotated by driving a motor. For example, when an operator requests the mounting table 40 to be rotated, the motor is driven to rotate the mounting table 40.

[0075] A container rack may be provided on the tip side of the mounting table 40. The container rack is rotatably supported on the mounting table 40. A ratchet is provided at the fulcrum of the container rack so as to rotate in one direction. When the container rack has rotated to a predetermined rotation end position, the ratchet can rotate the container rack in the opposite direction.

[0076] The transplanter 1 may have a seat 20 on the traveling transmission case 8 of the rear wheel 4 as shown in Fig. 18. Fig. 18 is a side view of the transplanter 1 according to a modified example. By providing the seat 20 on the traveling transmission case 8 of the rear wheel 4, the balance of the transplanter 1 can be stabilized.

[0077] A handle for operating the transplanter 1 may be provided in front of the seat 20. The handle may be provided with an accelerator operation device 26. For example, when the operator releases the accelerator operation device 26, the traveling vehicle body 2 decelerates, stops, or goes into an idle state.

[0078] Since the handle is provided on the transplanter 1, the operator can easily get on and off the transplanter 1. In addition, the distance from the accelerator operation device 26 to the driving source such as an engine is shortened, and the transplanter 1 can use a shorter harness. The accelerator operation device 26 may be provided on the step of the traveling body 2. The driving source may be a motor.

[0079] The transplanter 1 may have a seat 20 provided on the front side of the traveling body 2 as shown in Fig. 19. Fig. 19 is a side view of the transplanter 1 according to a modified example. The seat 20 is provided above the front side of the driving source 60. The accelerator operating device 26 is provided on a step provided on the front of the traveling body 2.

[0080] The transplanter 1 may be provided with a seating sensor below the seat 20. The transplanter 1 may stop the traveling body 2 when the seating sensor does not detect that an operator is seated on the seat 20.

[0081] The planting tool 5a may be configured to open slightly at the top when it is a planting tool for transplanting pineapple seedlings, for example. For example, in the planting device 5 shown in FIG. 20, as shown in FIG. 21, a part of the cam 70 is provided to bulge, so that the planting tool 5a opens slightly at the top. FIG. 20 is a diagram showing a planting device 5 according to a modified example. FIG. 21 is a diagram showing an example of the cam 70. In FIG. 21, the shape of a part of the cam of a comparative example in which the cam 70 does not bulge is shown by a broken line. The planting tool 5a closes when moving downward from the top. This allows the transplanter 1 to put the transplant up to the lower end side (rear side) of the planting tool 5a. Then, when the transplanter 1 subsequently transplants the transplant into the field using the planting tool 5a, it is possible to suppress the planting tool 5a from carrying the transplant back, and the transplant can be reliably transplanted into the field.

[0082] For example, when the planting tool 5a is a planting tool for transplanting pineapple seedlings, as shown in Fig. 22, a barb 71 may be provided facing downward by driving a barb into the inner surface from the outside. Fig. 22 is a diagram showing a part of the planting tool 5a according to a modified example. This allows the transplanter 1 to prevent the transplant from sliding upward when the planting tool 5a is closed.

[0083] As shown in Fig. 23, the planting tool 5a may have a plate 72 attached to the inside, which has a plurality of projections and recesses parallel to the opening and closing direction of the planting tool 5a. Fig. 23 is a diagram showing a part of the planting tool 5a according to a modified example. This allows the transplanter 1 to prevent the transplant from sliding upward when the planting tool 5a is closed.

[0084] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
