Description

[Technical Field]

[0001] The present invention relates to a transplanter in which a rotating marker is stored in a seedling carrier of a planting work device. [Background technology]

[0002] Conventionally, there is already known a transplanter in which a planting work device connected to a traveling body that can be raised and lowered has a rotating marker (line-drawing marker) with multiple protruding lugs attached to an arm attachment part and a support arm, which are attached to a shed or the like in a storage position where the rotating marker alone is removed from the working position (line-drawing position) and attached along the side of the seedling-loading table (seedling-loading part) to draw a line on the field, leaving a marker mark that serves as a travel guide (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-73052 Summary of the Invention [Problem to be solved by the invention]

[0004] The marker device shown in Patent Document 1 above has a holding arm that inserts and supports the rotating marker removed from the support arm, and a fixing spring that fixes the spokes of the rotating marker, attached to arm support brackets attached to the left and right front of the seedling carrier of the planting work device.This has the advantage that the rotating marker removed from the planting work device can be quickly attached to the side of the seedling carrier, making storage work easy. However, the rotating marker, which is stored and supported above the side of the seedling carrier via a crank-shaped holding arm, is supported in a cantilevered position on the side of the carrier and protrudes significantly toward the top rear.Therefore, when traveling long distances in this stored position on roads from the field to a barn far from the field, it constantly vibrates violently back and forth and side to side, and when exposed to strong winds, the wind pressure can easily deform the mounting parts such as the holding arm (marker support rod). Therefore, in order to provide stable cantilever support while suppressing resonance and withstanding severe vibrations and wind pressure in a cantilevered state, each mounting member must have a rigid structure with sufficient strength. On the other hand, if one tries to make it easier to attach and remove the rotating marker, a fixed spring mechanism with excellent strength and structure for vibration damping is required, which also creates the problem of complicated structure and components and high costs. Furthermore, planting work devices that store their seedling carriers in a vertical position with the rotating marker protruding significantly above the seedling carrier stand have the problem of getting in the way when placing materials related to transplanting work or other equipment on top of the seedling carrier stand, preventing effective use of the seedling carrier stand of the planting work device. Therefore, the present invention solves the conventional problems and provides a planting work device that can load and store various materials without being obstructed by the rotating marker 26 stored on the seedling carrier by storing the rotating marker 26, which is not left on the traveling body side, in a flat storage position without protruding significantly outward from the left and right sides of the seedling carrier, and which does not cause any interference with the seedling carrying surface of the seedling carrier due to vibration or wind pressure. [Means for solving the problem]

[0005] The transplanter of the present invention for solving the above problems comprises: First, in a transplanter 1 having a planting device 6 attached to the rear of a traveling body 2 having front wheels 1a and rear wheels 1b, and a marker device 10 extending laterally from a seedling carrier 8 of the planting device 6 to draw lines on a field, the rotating marker 26 being detachable from the marker device 10 and retractable on the planting device 6 side, The rotating marker 26 removed from the marker device 10 side is supported in a storage position facing the front or back side of the loading surface 8b of the seedling loading platform 8 in a plane, and an attachment means 35 is provided to fix and support the marker support rod 27 of the rotating marker 26 along the seedling loading platform 8, so that the rotating marker 26 removed from the marker device 10 side can be freely stored along the seedling loading platform 8 in a plane. Secondly, part or all of the rotating marker 26 is placed flat on the loading surface 8b between the left and right seedling partition walls 8c formed on the seedling loading platform 8, and the marker support rod 27 is inserted into the slit 8e formed on the loading surface 8b, and is fixed and supported in a storage position by an attachment means 35 provided on the back side of the seedling loading platform 8. Thirdly, the attachment means 35 is characterized by being configured with a magnet body 46 that can detachably attract and fix the marker support rod 27. [Effects of the Invention]

[0006] According to the invention of claim 1, a transplanter 1 is provided with a planting device 6 attached to the rear of a traveling body 2 having front wheels 1a and rear wheels 1b, and a marker device 10 that projects laterally from the seedling carrier 8 of the planting device 6 to draw lines on a field scene, and a rotating marker 26 that can be removed from the marker device 10 and stored on the planting device 6 side, and the rotating marker 26 removed from the marker device 10 side is supported in a stored position facing the front or back side of the seedling carrier surface 8b in a plane, and an attachment means 35 is provided to fix and support the marker support rod 27 of the rotating marker 26 along the seedling carrier 8, so that the rotating marker 26 removed from the marker device 10 side can be stored along the seedling carrier 8 side in a plane, The rotating marker 26 removed from the marker device 10 can be stably supported in a planar storage position facing the front or back side of the loading surface 8b of the seedling loading platform 8, and the marker support rod 27 of the rotating marker 26 can be fixed and supported in a stable position along the seedling loading platform 8 by the attachment means 35 without placing a large storage load on the marker support rod 27. Furthermore, the planting work device 6, which is stored in a barn or garage together with other materials and equipment, does not have the rotating marker 26 protruding vertically significantly above the seedling carrier 8, which has the advantage that surrounding equipment can be placed directly, quickly, conveniently and efficiently on top of the seedling carrier 8 during long-term storage such as off-season, or at any time. According to the invention of claim 2, a part or all of the rotating marker 26 is placed flat on the loading surface 8b between the left and right seedling partition walls 8c formed on the seedling loading platform 8, and the marker support rod 27 is inserted into the slit 8e formed on the loading surface 8b, and is fixed and supported in a storage position by the attachment means 35 provided on the back side of the seedling loading platform 8. The rotating marker 26 can be stored flatly, compactly and with high stability without protruding significantly upward or outward from the seedling carrier 8, and the marker support rod 27 is placed in a stored position along the back side of the seedling carrier 8 through the slit 8e, so that a series of storage operations such as storing and removing the marker part 20 into and from the seedling carrier 8 can be performed efficiently with a simple and inexpensive configuration. The rotating marker 26 placed flat on the loading surface 8b of the seedling loading platform 8 is stably supported with its left and right movement restricted by the left and right seedling partition walls 8c, and since it does not protrude significantly upward from the seedling partition walls 8c, it can be used as a loading platform without being hindered. According to the third aspect of the present invention, the attachment means 35 is configured by providing a magnet body 46 that can detachably attach and fix the marker support rod 27, The magnetic attraction force of the magnet body 46a makes it easy to fix and support the marker support rod 27, and also securely locks the marker support rod 27 against external forces such as vibrations caused by the vehicle's running and wind pressure, preventing the marker support rod 27 from coming off.

DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of the present invention will be described with reference to the drawings. In Figures 1 and 2, reference numeral 1 denotes a transplanter exemplifying a riding rice transplanter, which has a running body 2 with front wheels 1a and rear wheels 1b on the left and right, an engine mounted in front of the running body 2 and covered with a hood 3, and a control unit 4 at the rear, which is comprised of a handle 4a of an operation panel, a seat 4b, and a control floor 4c placed between the two. Furthermore, floor steps 7 are provided on the left and right of the control step 4c.

[0009] The traveling machine body 2 is equipped with a planting device 6 that can be freely attached, detached, and raised and lowered via a three-point linkage lifting mechanism at the rear of the machine body. The planting device 6 has a similar configuration to conventional devices, and moves a seedling carrier 8, which carries eight rows of mat seedlings in a left-right parallel arrangement, back and forth in an inclined position with a high front and a low rear, while seedling planting claws 9, which are positioned so that they can pick up and plant each of the eight rows of mat seedlings, pick up the seedlings from the apron 8a of the seedling carrier 8 and plant them in the field (paddy surface). As shown in Figures 2 and 3, marker devices 10 according to the present invention are arranged symmetrically on the left and right sides of the planting device 6, and are configured to perform marker work by leaving marker tracks (planting travel tracks) on the unplanted side of the paddy field, which is the next step in planting.

[0010] The planting work device 6 has a horizontal planting frame 11 to which a plurality of planting claw transmission cases 12, each having a planting claw unit that rotates and drives the planting claws 9, are attached at a predetermined interval, and a sled-shaped float 13 is provided at the bottom of each planting claw transmission case 12 via a support link mechanism. The seedling carrier 8 has its lower rear end placed on an apron 8a attached along the planting section frame 11, and its upper front side is supported so that it can slide freely while being placed on a slide support section.The lower part of the back side is connected to a seedling carrier drive section installed on the planting claw transmission case 12 side, allowing the seedling carrier 8 to be driven back and forth freely in the horizontal direction.

[0011] The planting work device 6 thus constructed drives the seedling carrier 8 back and forth in a lateral direction to feed the seedlings, while the planting claws 9 scrape the seedlings from the apron 8a of the seedling carrier 8 and plant them in the paddy field. When the transplanter 1 travels back and forth within the field to perform planting work, one of the marker devices 10 facing the unplanted side of the field is switched to a working position (line-drawing working position) in which it leaves a marker mark on the field soil surface such as the rice field surface and draws a line, and the other marker device 10 is lifted upward via the arm attachment portion 17 and arm 19 (described later) and rotated away from the rice field surface to switch to a non-line-drawing working position, thereby continuously performing back and forth process marker work.

[0012] The marker device 10 will be described with reference to Figures 2, 3, and 5. The right marker device 10 is composed of arm attachment parts 17 formed on the left and right ends of the planting frame 11, a marker arm (hereinafter simply referred to as arm) 19 rotatably supported on the arm attachment part 17 via a mounting shaft 18 in the front-to-rear direction, and a marker part 20 attached to the tip of the arm attachment part 17 in a detachable and replaceable manner. In addition, the arm 19 in this embodiment comprises a base arm 19a made of a large diameter pipe pivotally supported on the arm mounting portion 17, and a tip arm 19b made of a small diameter pipe fixed integrally to the tip of the base arm 19a, and the marker portion 20 is removably attached to the tip side of the tip arm 19b via a holding mechanism 30 constructed using a known structure.

[0013] As shown in Figures 2 and 3, the arm mounting portion 17 of the marker device 10 is attached to a plate-shaped bracket 21 attached to the front end of the planting frame 11 by inserting the arm bracket integrally formed on the base arm 19a into the mounting shaft 18 so that it can rotate freely, and is connected to the planting frame 11 side by a spring 23 for maintaining posture. This allows the arm 19 to rotate between the working position shown by the solid lines in Figure 2 and the storage position in which the arm 19 is raised approximately vertically as shown by the dotted lines and the rotating body marker 26 is in a sideways position in an approximately horizontal position, and the tension direction of the spring 23 is switched between one side of the mounting shaft 18 and the other, so that the arm 19 can be maintained in either the working position or the storage position.

[0014] The attitude of the marker device 10 can be changed by pushing and pulling a wire using a lever (not shown) from the control unit 4 side, or by automatic switching using an actuator such as a motor based on the switching operation of switches. When traveling on the road, a support 25 protruding from an appropriate position on the frame member of the planting section frame 11 engages and supports the middle part of the arm 19 in the storage position shown by the dotted line in a freely detachable manner.

[0015] Next, the marker unit 20 of this embodiment will be described with reference to Figures 2 and 4 to 7. This marker unit 20 is composed of a rotating marker 26 that comes into contact with the rice field surface to leave a marker mark, and a crank-shaped marker support rod 27 that attaches and supports the rotating marker 26 to the arm 19. The marker support rod 27 has a straight rod portion 27a extending in the vertical direction, an inward-facing mounting rod portion 27b at its upper portion which is inserted and supported within the tip arm 19b, and a horizontal rod portion 27c at its lower portion which has a support width and supports the rotating body marker 26 in a cantilevered manner, allowing it to rotate freely.

[0016] The rotating body marker 26 in the illustrated example has a windmill-shaped design that includes a boss portion 28 that is rotatably inserted into the horizontal rod portion 27c, multiple spoke portions 28a extending radially from the boss portion 28, a ring portion 28c that is supported by the spoke portions 28a and has multiple spatula-shaped claw protrusions 28b protruding from its outer periphery, and multiple lightening holes that are formed when the synthetic resin is formed, similar to conventional ring-shaped rotating body markers. When the marker unit 20 is placed in the working position with the marker support rod 27 attached to the holding mechanism 30, which is constructed by a known structure on the tip arm 19b, the rotating marker 26 can be made to face the marker position on the rice field surface from the planting work device 6, and as it rotates in contact with the ground as it moves, each claw protrusion 28b sequentially scrapes up the soil, forming a dotted marker mark (marker line).

[0017] In the embodiment, the rotating body marker 26 has a boss portion 28 formed in the center that is inserted removably into the horizontal rod portion 27c, and is positioned and supported by a locking member (not shown) that is removably attached to the shaft end of the horizontal rod portion 27c. With this configuration, the rotating body marker 26 can be slid outward from the horizontal rod portion 27c and pulled out once the locking member is released, making it easy to replace the rotating body marker 26.

[0018] As shown in Figures 2 and 3, when the marker portion 20 is pulled out and removed from the mounting member 31 provided at the tip of the arm 19, the holding mechanism 30 performs the reverse operation of the mounting work to disengage the hook portion of the elastic member 32 from the straight rod portion 27a, freeing the marker support rod 27, and allowing the mounting rod portion 27b to be pulled out to the side with a single touch. The marker part 20 removed from the holding mechanism 30 utilizes the front (upper) slope of the front side of the seedling carrier 8, which is in an inclined position with the front high and the rear low, or the flat surface of the back (lower) slope, and by using the seedling carrier storage method that utilizes the mounting means 35 related to the present invention and other mounting means not shown, the marker part 20 can be stored stably in a space-saving manner that does not take up much space in the vertical direction due to its flat storage position, without protruding significantly outward from the left and right sides of the seedling carrier 8 along the flat surface of the seedling carrier 8.

[0019] The mounting means 35 of the marker part 20 and the seedling carrier storage method will be described with reference to Figs. The mounting means 35 consists of a mounting base 36 that is removably attached and fixed to the back side of the seedling carrier 8, and a fixing part 37 that supports the marker support rod 27 of the marker part 20 on the mounting base 36 in a planar opposite relationship along the seedling carrier 8. This allows the rotating marker 26 and marker support rod 27 of the marker unit 20 to be stored stably, flatly, and compactly without protruding outward from the front of the seedling carrier 8, and the simple, inexpensive configuration makes it possible to efficiently perform a series of storage operations, such as storing, installing, and removing the marker unit 20.

[0020] First, the basic structure of the seedling carrier 8 and the configuration related to the present invention will be described. This seedling carrier 8 has seedling partition walls 8c protruding from both sides of the seedling carrier surface 8b on which eight rows of mat seedlings are individually placed, each with a height equivalent to the thickness of the mat seedlings, and the upper back sides of adjacent seedling carrier surfaces 8b are connected in series by horizontal carrier frames 38 for reinforcement. A plurality of extension seedling carriers 8d, which supplementarily extend the seedling carrier surface 8b, are detachably attached to the upper side of the base frame 38 at adjacent intervals (slits 8e) above the surface 8b. Each extension seedling carrier 8d has a plurality of elongated slits 8e formed in the width direction of the seedling carrier surface.

[0021] In this configuration, as shown in Figures 4 to 7, the mounting base 36 has a flat mounting surface 36a for mounting the marker support rod 27, and an upper foot portion 36b and a lower foot portion 36c bent above and below the flat mounting surface 36a, forming a U-shape when viewed from the side, and a fastener 40 such as a bolt or screw is provided in the center of the mounting surface 36a. As a result, the mounting base 36 is positioned so as to straddle the base frame 38, and by fastening the stopper 40 to a stopper portion (not shown) provided on the base frame 38 side, it can be installed easily and detachably on the seedling carrier 8 side with a simple and inexpensive configuration while maintaining mounting rigidity. The mounting base 36 is provided with a guide hole 36d cut out in a predetermined size at the center of the left and right of the bent portion between the mounting surface 36a and the upper leg portion 36b.

[0022] This guide hole 36d flexibly guides the bent portion of the marker support rod 27 formed by the horizontal rod portion 27c and the straight rod portion 27a, allowing the marker support rod 27 to be quickly and smoothly positioned and aligned in the appropriate position relative to the mounting base 36. The mounting base 36 has mounting holes 41 and 42, 42 drilled and formed at predetermined angles and distances in a triangular arrangement in a plan view at symmetrical positions centered on the stopper 40 provided in the center of the square, flat mounting surface 36a, thereby forming a mounting means 35 to which the support member 45 and the locking member 46 that constitute the fixed portion 37 can be separately attached. The illustrated attachment means 35 shows a mode in which the removed left marker portion 20 is arranged on the left side of the seedling carrier 8 to form a left storage structure in which it can be placed in a storage position.

[0023] As a result, as shown in Figure 4, when the left-side marker part 20 is placed on the seedling carrier 8 or the extended seedling carrier 8d or both, and the marker support rod 27 is inserted into the slit 8e or a slit (not shown) formed directly in the seedling carrier 8, the marker support rod 27, which tends to hang down vertically downward or rotate sideways due to its own weight, is received and fixed by the mounting means 35 at a suitable storage support angle in the storage position, so that the rotating marker 26 can be stored and supported in a predetermined optimal support posture facing the seedling carrier 8 in a plane. The support angle (support tilt angle) of the marker support rod 27 can be adjusted by the mounting relationship between the mounting base 36 and the fixing portion 37, which will be described below.

[0024] On the other hand, the mounting base 36 and the fixing part 37 configured as above can be used in combination to create a right-side arrangement structure in which the right-side marker part 20 can be placed in a storage position that is conveniently arranged on the right side of the seedling carrier 8. In this case, by removing the fixing bolts 42a, 42a, the removed locking member 46 can be bolted to the right-side mounting holes 42, 42 via the fixing bolts 42a, 42a as viewed in Figures 4 and 6, and then the bolt 45b described below can be removed and the removed support member 45 can be bolted to the right-side mounting hole 41 via the bolt 45b.

[0025] This allows the right-side marker support rod 27 to be stored and supported in a suitable position similar to that of the left-side marker support rod 27, with a position and posture symmetrical to that of the left-side storage mode, and also allows the components of the left and right mounting means 35 to be used interchangeably. The configuration and usage of the right-side mounting means 35 are provided with a structure symmetrical to that of the left-side mounting means, and the storage operation is performed by the operation of use, so a redundant explanation will be omitted.

[0026] Next, the specific structure of the support member 45 and the locking member 46 that constitute the fixed portion 37 of the mounting base 36 of the left mounting means 35 shown in the drawing, as well as the method of retracting the mounting member 45 and the locking member 46 will be described. The support member 45 is attached and fixed in an inclined position toward the center of the seedling carrier 8 or toward the outside of the seedling carrier 8, and is shaped to receive the marker support rod 27 halfway toward its base when it is inserted through the slit 8e and attempts to hang down vertically. The illustrated locking member 46 is configured to have a magnet body 46a that can magnetically attract and fix the marker support rod 27 in a detachable manner.

[0027] In this way, the mounting means 35 configured on the back side of the seedling carrier 8 near the slit 8e allows the operator to easily visually check the rotating body marker 26 near the bottom when inserting the marker support rod 27 into the slit 8e above the seedling carrier 8 and placing the rotating body marker 26 in a storage position. Therefore, the marker support rod 27 inserted through the slit 8e can be received and supported in an inclined position by the support member 45, so that the free end of the marker support rod 27 can be received and supported stably and quickly in an inclined position without dropping down, and the marker support rod 27 can be stored in a position that avoids contact between the marker support rod 27 and various structures arranged below the back side of the seedling carrier 8.

[0028] The marker support rod 27 in the inclined position can be quickly and automatically attracted and fixed in a predetermined stable position by magnetic force while its own weight is applied to the magnetic body 46a of the locking member 46, and the worker can support it in the stored position with one touch by simply releasing his / her hand at the predetermined position without using any tools. When removing the rotating body marker 26 from the stored position, the worker can simply grasp the middle part of the marker support rod 27, which is in an inclined position that makes it easy to grip, and lift it up against the magnetic force, without using any tools, to remove it from the locking member 46.Then, by simply lifting the rotating body marker 26 upward, the stored position can be released and it can be quickly removed.

[0029] Furthermore, the mounting means 35, which is equipped with a locking member 46 consisting of a magnet body 46 that detachably attracts and fixes the marker support rod 27, receives and guides the weight of the marker support rod 27 onto the support member 45 of the fixed portion 37, and leads it to the locking member 46, where the weight is firmly supported by the suction action of the locking member 46, and the locking function described below has the characteristic of reliably maintaining the inclined posture against severe vibrations of the aircraft, preventing it from coming off.

[0030] The series of storage operations using the transplanter 1 equipped with the above-configured mounting means 35 can be performed by the operator standing in the field outside the seedling carrier 8 when the mounting means 35 is installed on the side of the seedling carrier 8, and when the mounting means 35 is installed on the inside of the seedling carrier 8, the operation can be performed conveniently, easily, smoothly and efficiently in a riding position using the work step section 7c, etc. In other words, the setting work of storing the rotating marker 26 on the seedling carrier 8 can be done simply, reliably and quickly by holding the rotating marker 26 in the right or left hand and positioning and supporting it at a predetermined position on the seedling carrier 8, while using the other outstretched hand to guide the marker support rod 27 inserted into the slit 8e into the support member 45 and the locking member 46.

[0031] Furthermore, in the case of a multi-row planting type transplanter 1 with four or more rows, for example, when the rotating body marker 26 is stored on the seedling loading surface 8b on the inner side of the seedling loading platform 8 as in the illustrated example, it is often difficult to operate the storage work while standing in the field by reaching in from the side, but there is an advantage in that the storage work using the work step portion 7c can be performed efficiently in a stable posture by utilizing the large space formed above the seedling loading platform 8.

[0032] The configuration of the mounting means 35 for this purpose is as shown in Figures 5 and 6, in which the support member 45 of the strip-shaped plate is formed into a crank shape when viewed from the side, and its base piece 45a is attached and fixed to one of the mounting holes 41 with a bolt 45b.The locking guide piece 45c formed at the tip of the strip-shaped plate receives and guides the middle part of the marker support rod 27, and supports and guides it downward between the mounting base 36 so that it can be securely abutted against the locking member 46 and engaged.

[0033] The locking member 46 in the illustrated example is bolted along the plane of the mounting base 36 via fixing bolts 42a, 42a, and is attached and supported within the lower part of the support member 45.The locking member 46 in the embodiment is composed of a magnetic body 46a that can lock (attach and fix) the middle part of the marker support rod 27 by magnetic force, and a magnetic base 46b that supports the magnetic body 46a and has bolt holes for inserting the fixing bolts 42a, 42a into the mounting base 36, making it detachable. With this arrangement, the locking member 46 can adjust the mounting angle of the direction of the locking surface of the magnet body 46a of a predetermined length relative to the mounting base 36 via the fixing bolts 42a, 42a and the respective bolt holes.

[0034] This allows the fixing portion 37 of the mounting means 35 to be mounted at an angle that aligns the locking surface of the magnet body 46a with the desired inclination angle of the inclined posture required for the marker support rod 27 when the rotating body marker 26 is stored. This allows the magnet body 46a to efficiently exert a locking force due to magnetic attraction, securely locking the marker support rod 27 against external forces such as the vehicle's running vibrations and wind pressure, and has the advantage of allowing the marker support rod 27 to be moved quickly and without coming off with a simple configuration.

[0035] Furthermore, when the magnet body 46a is subjected to large vibrations such as bouncing while the vehicle is running, even if the marker support rod 27 becomes misaligned from the magnet body 46a, the locking guide piece 45c of the support member 45, which is installed adjacent to the specified location, receives and guides the marker support rod 27 to maintain its position, making it possible to use a low-magnetic-force magnet body 46a and resulting in an inexpensive configuration. On the other hand, when removing the marker support rod 27 from the magnet body 46a, it can be removed with a single touch by simply pulling it against the locking force, without using any tools or fasteners.

[0036] Therefore, when removing the rotating marker 26 from the seedling carrier 8 having the above-mentioned storage means, the marker support rod 27 can be detached in a single touch by simply pulling it with one hand against the locking force, and then the rotating marker 26 can be removed from the locking guide piece 45c by pulling and rotating it around the boss portion 28 of the rotating marker 26 as a fulcrum.At the same time, the rotating marker 26 can be lifted upward with the other hand, and the marker support rod 27 can be easily pulled out of the slit 8e in the correct position, allowing the rotating marker 26 to be quickly removed from the seedling carrier 8 without any tools.

[0037] Furthermore, a transplanter 1 equipped with a seedling carrier 8 on which the rotating marker 26 is stored flatly can facilitate loading and storing of other materials and equipment in a barn or garage, etc., and since the rotating marker 26 does not protrude vertically significantly above the seedling carrier 8, this creates the advantage of promoting the use of the seedling carrier 8 for loading and storing items, such as when storing the planting work device 6 detached from the transplanter 1 or running body 2 for a long period of time, such as during the off-season, or when temporarily placing surrounding equipment directly on top of the seedling carrier 8.

[0038] In the above embodiment, the attachment means 35 is composed of a magnet body 46 that magnetically attracts and fixes the marker support rod 27, but it is not limited to this and can be adapted to the storage position of the rotating body marker 26, etc., and can be, for example, a spring member that elastically clamps the rod body of the marker support rod 27 in a manner that allows it to be freely attached and detached, or it can be composed of an attachment and detachment fixing means such as a means for wrapping a rubber band around it and pulling it to fix it, or a hook-like structure that allows it to be freely attached and detached. In addition, the slit 8e in the illustrated example is an embodiment formed in an extended seedling carrier 8d that extends the carrier surface 8b of the seedling carrier 8, but in a type of seedling carrier 8 that does not have the extended seedling carrier 8d, the slit 8e may be formed in the upper part of the seedling carrier 8, and the marker support rod 27 inserted into the slit 8e may be temporarily supported in a storage position by an attachment means 35.

[0039] Furthermore, when the slit 8e is formed on the lower side of the seedling carrier 8, the marker support rod 27 of the rotating body marker 26 placed flatly on that portion can be passed through the slit 8a in an upwardly extending position, and its upwardly facing upper end can be temporarily supported in a storage position by an attachment means 35. Furthermore, the mounting means 35 that restricts downward or lateral movement of the marker support rod 27 along the seedling carrier 8 is not limited to the above embodiment, but may also be configured to be mounted and fixed using a detachable hook member or a rubber or string-like band member.
