[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] The rice transplanter of this embodiment is an example of a transplanter in the present invention.

[0026] First, with reference to Figs. 1(a) to 1(c) and 2, the configuration and operation of the rice transplanter of the present embodiment will be specifically described.

[0027] Here, Figure 1(a) is a schematic plan view of a rice transplanter of an embodiment of the present invention, Figure 1(b) is a schematic front view of a rice transplanter of an embodiment of the present invention, Figure 1(c) is a schematic left side view of a rice transplanter of an embodiment of the present invention, and Figure 2 is a block diagram of the power transmission system of a rice transplanter of an embodiment of the present invention.

[0028] The rice transplanter of this embodiment is a riding mat seedling rice transplanter for planting 12 rows, and the planting device 100 has six planting units, and each planting unit has a pair of two planting tools, one on the left and one on the right.

[0029] Of course, the rice transplanter is not limited to a riding mat seedling rice transplanter for planting 12 rows, but may be, for example, a riding pot seedling rice transplanter for planting 10 rows.

[0030] First, the basic configuration and operation of the rice transplanter of this embodiment will be described. Therefore, the spare seedling loading table 200 and the like will be described in detail later.

[0031] The driving unit 50 has a seat 51 provided above the engine 20 .

[0032] A steering handle 52 for operating the front wheels 31 is provided in front of the seat 51. A horizontal step floor 53 is provided on both the left and right sides of the engine 20. Furthermore, a spare seedling carrying platform 200 is provided on the vehicle body 10.

[0033] The traveling device 30 is a device that causes the vehicle body 10 to travel using front wheels 31 and rear wheels 32.

[0034] The soil leveling device 60 is a device that levels the field using a soil leveling rotor mechanism and a soil leveling float mechanism.

[0035] A line drawing marker is attached to the vehicle body 10 in a storable manner to form straight line markings in the field as a guide for the next planting travel route.

[0036] The planting device 100 is attached to the rear side of the vehicle body 10 via a planting device lifting device.

[0037] The rotational power of the engine 20 attached to the main frame is transmitted to the main transmission mechanism 41, which is an HST (Hydro Static Transmission) mechanism, etc. The rotational power changed in speed by the main transmission mechanism 41 and the sub-transmission mechanism 42 is separated into running power used by the traveling device 30, etc., and externally taken power used by the planting device 100, etc.

[0038] A part of the running power is transmitted to the left and right front wheel final cases to drive the pair of left and right front wheels 31, and the rest of the running power is transmitted to the left and right rear wheel gear cases 43 to drive the pair of left and right rear wheels 32. Then, a part of the running power transmitted to the rear wheel gear cases 43 is transmitted to the soil leveling device 60 and the fertilizing device 70.

[0039] Next, the configuration and operation of the rice transplanter of this embodiment will be described more specifically with reference mainly to FIGS. 1(a) to 1(c).

[0040] The spare seedling carrying platform 200 is a spare seedling carrying platform that can move left and right above the vehicle body 10 and on which seedlings are placed. The seedling carrying device 80 is a seedling carrying device supported on the rear side of the vehicle body and on which seedlings are placed when planting. The seedlings can be loaded by sliding from the rear end of the spare seedling carrying platform 200 to the seedling carrying device 80.

[0041] The seedling loading device 80 is moved back and forth in the left-right direction of the vehicle body with the seedlings loaded when planting. The seedlings are transported in the front-rear direction of the vehicle body and loaded onto the seedling loading device 80 by sliding movement from the rear end of the spare seedling loading platform 200.

[0042] 1(a) to 1(c), long rails are provided in the left-right direction indicated by arrows in front of the hood at the front of the machine body and behind the seat at the rear of the machine body, respectively, at a position higher than the steering handle 52 and the seat 51. A long auxiliary seedling frame (seedling rails) of the spare seedling loading platform 200 is provided at the front and rear of these two rails. This auxiliary seedling frame (seedling rails) is configured to slide left and right on the two rails provided in the left-right direction, always perpendicular to the rails. This auxiliary seedling frame (seedling rails) is positioned at a position higher than the steering handle 52 and the seat 51, and moves past it when moving left and right.

[0043] This allows the auxiliary seedling frame (seedling rail) to be moved anywhere to the left or right on the machine's running section, so it can be moved to the front of the row to which seedlings are to be replenished in the seedling tank in the planting section of the seedling loading device 80, or to a location on the ridge close to where the auxiliary seedlings are placed.This shortens the distance that the auxiliary seedlings need to be transported when replenishment of seedlings, resulting in a reduction in work labor.

[0044] 1(a) to 1(c), long rails are provided in the left-right direction at the front and rear of the machine body, and a long seedling rail is placed on this rail and moved left and right, in which the long seedling rail extends from the front of the bonnet at the front of the machine body, and from the front of the seedling tank in the planting section at the rear of the machine body to above the mid-fertilizer applicator of the fertilizer applicator 70. In addition, the fertilizer hopper lid of the mid-fertilizer applicator is divided into two parts, left and right.

[0045] By extending the rear to just before the seedling tank, the seedling rail is closer to the planting area, making seedling supply easier and reducing the labor required. Also, because it is long at the rear, the front can be secured to the length of three auxiliary seedlings vertically within the range of the running section without protruding from the machine body, making it easy to use and easy to work in a work environment with obstacles. In addition, by dividing the mid-fertilizer applicator fertilizer hopper cover into two, the seedling rail can be moved left and right to supply fertilizer to each half, allowing for problem-free work.

[0046] 1(a) to 1(c), long rails are provided in the left-right direction at the front and rear of the machine, and a long rail is placed on the rails and moved left and right. In this configuration, a step 610 is provided in front of the bonnet at the front of the machine, with enough space for an operator to stand with both feet on it. In addition, this step 610 is configured so that it can be folded up at an angle of 90 degrees toward the bonnet in the direction indicated by the arrow.

[0047] As a result, when moving the seedling rail left and right, the operator riding on the machine must step over or pass under the rail to avoid it, but by standing on this step, the operator can move the seedling rail in front of him, improving workability. Also, when the seedling rail is positioned in the center of the left and right, the operator can move the step left and right from the front of the hood, improving workability. This step 610 can be folded up so that the overall length of the machine does not need to be extended, and it can be used in a variety of ways depending on the work environment, such as obstacles.

[0048] As shown in Figures 1(a) to 1(c), long rails are provided in the left-right direction at the front and rear of the machine, and long seedling rails are placed on these rails and moved left and right. The seedling rails are arranged horizontally in two rows in one unit. In addition, three auxiliary seedlings are placed vertically in the front-to-back direction, making it possible to load a total of six seedlings in a six-row rice transplanter. For an eight-row rice transplanter, if the front of the machine is extended and four seedlings are placed vertically, a total of eight seedlings can be loaded. In this case, the seedling rails protrude from the front end of the machine, so one of the protruding parts is made foldable or made to move with a link, like the so-called Z seedling rail.

[0049] This allows two rows (two rows) to be moved together, and seedlings can be replenished by moving two rows at a time, improving work efficiency and workability. In addition, in the case of 6-row and 8-row rice transplanters, auxiliary seedlings can be loaded for the number of rows.

[0050] 3(a) and 3(b), which are schematic plan views (parts 1 and 2) of the spare seedling loading platform 200 of a rice transplanter according to a modified embodiment of the present invention, long rails are provided in the left-right direction at the front and rear of the machine body, and long seedling rails are placed on these rails and moved left and right, in a configuration in which the seedling rails are integrated into two horizontal rows and three vertical rows in size, the spare seedling loading platform partition section 620, which is the partition between the two horizontal rows, is made removable. Here, the width when the partition is removed is made to be equal to or greater than the length of the long side of the auxiliary seedlings, so that the auxiliary seedlings can be loaded sideways.

[0051] This allows the auxiliary seedlings arranged in two horizontal rows to be slid horizontally in the direction indicated by the arrows by removing the partition, so that when the row in front of the operator who is replenishing the seedlings runs out, the auxiliary seedlings in the back row can be moved forward and removed, improving workability. Also, by making it possible to load the auxiliary seedlings sideways, the auxiliary seedlings can always be positioned in front of the operator, allowing for a configuration that can be used according to the operator's preferences and ease of use.

[0052] As shown in Figure 3(c), which is a schematic plan view of the vicinity of the seedling loading device 80 of a rice transplanter in a modified embodiment of the present invention, long rails of a spare seedling loading platform 200 are provided in the left-right direction at the front and rear of the machine body, and long seedling rails are placed on these rails and moved left-right. In this configuration, the seedling rails are arranged in two horizontal rows, and are configured on both the left and right sides so that the row inside the machine body can be moved to the front of a position where the seedling tank in the planting section of the seedling loading device 80 is closer to the end farther from the center of the machine body.

[0053] This improves workability by eliminating problems such as the difficulty of reaching the rows at the edge of the seedling tank and dropping the seedlings or putting them in at an angle, even for small operators. Also, the space above the step floor 53 on which the operator moves can be made wider, further improving workability.

[0054] 1(a) and 1(b), long rails of the spare seedling loading platform 200 are provided in the left-right direction at the front and rear of the machine body, and a long seedling rail is placed on this rail and moved left and right, the long seedling rail is arranged diagonally so that the rear end is lowered, and the rear end of the seedling rail is adjusted to the height of the tip of the extended seedling tank when the seedling tank in the planting section of the seedling loading device 80 is at the highest raised height. Here, the auxiliary seedlings can be directly loaded onto the seedling rail after being removed from the seedling box, and the fence at the rear end of the seedling rail of the seedling fence member 300 can be rotated backward to open, and this fence can be configured to be the joint surface with the seedling tank.

[0055] As a result, when an operator on the machine supplies seedlings to the seedling tank, he or she only needs to open the rear end fence of the seedling rail and slide the auxiliary seedlings into the seedling tank, eliminating the need to scoop up and carry the seedlings with a seedling picking board on the narrow, slippery step floor 53 or to dispose of empty boxes, improving workability.

[0056] Further, a modified embodiment of the present invention will be described.

[0057] The inclination of the spare seedling carrying platform 200 can be adjusted in the fore-aft direction of the vehicle body.

[0058] When the seedlings are moved from the front end of the spare seedling stand 200 toward the rear end of the spare seedling stand 200, the inclination of the spare seedling stand 200 is adjusted so that the height of the front end of the spare seedling stand 200 becomes greater than the height of the rear end of the spare seedling stand 200.

[0059] A more specific explanation is as follows.

[0060] As shown in Fig. 4(a) which is a schematic left side view (part 1) of a rice transplanter according to a modified embodiment of the present invention, and Fig. 4(b) which is a schematic left side view of a spare seedling loading platform support 630 of a rice transplanter according to a modified embodiment of the present invention, the long rails of the spare seedling loading platform 200 are provided in the left and right directions at the front and rear of the machine body, and the long seedling rails are placed on these rails and moved left and right, and the height of the two long rails in the left and right directions can be freely changed. Any configuration can be used to change the height, but a simple configuration such as doubling the pipe of the spare seedling loading platform support 630 of the spare seedling loading platform 200, drilling holes in the pipes, and fixing them with a pin 631 at a desired height will do. The front and rear rails can be changed in height independently of each other.

[0061] This allows adjustments to suit the working environment, such as adjusting the height to suit the physique of the operator who supplies seedlings, adjusting the inclination of the entire seedling rail to adjust how the seedlings slide, and adjusting the height to make it easier to supply seedlings from the ridges, improving usability and workability.In addition, by lowering only the front rail to make the front slope downward, it can be used to collect leftover seedlings and empty boxes after work, making it possible to use it in a variety of ways.

[0062] As shown in Figure 4(a), long rails are provided in the left-right direction at the front and rear of the body, and a long seedling rail is placed on this rail and moved left and right.When changing the height of the two long rails to lower the height of the entire seedling rail, the steering handle 52 can also be tilted significantly rearward and lowered, and the seat backrest of the seat 51 can be folded forward into the seating surface.

[0063] As a result, even if the height of the seedling rail is lowered, by lowering the steering handle 52 and the seat backrest so that they are stored, the low-positioned seedling rail can be moved left and right without hitting the steering handle 52 or the seat backrest, improving workability. With an unmanned robotic rice transplanter, if actual work is carried out in this state, it is easy to supply seedlings from the ridges, and it is also effective because the operator's steering handle 52 and seat 51 can be extended if an operator is required.

[0064] As shown in Fig. 4(c), which is a schematic plan view (part 1) of a rice transplanter according to a modified embodiment of the present invention, long rails of spare seedling loading platform 200 are provided in the left-right direction at the front and rear of the machine body, and long seedling rails are placed on these rails and moved left and right, in a configuration in which the seedling rails arranged in two horizontal rows can be separated into spare seedling loading platform parts 641 and 642, one row at a time, and each row can be moved independently in the left and right directions as indicated by the arrows. It is also possible to connect two of the separated seedling rails from one row to return to two horizontal rows.

[0065] This allows two seedling rails in a horizontal row to be placed on the left and right sides of the machine, and if the operator fits between them, it can be used in the same way as a conventional auxiliary seedling frame and seedling rail, creating a user-friendly configuration that can be tailored to the operator's preferences.

[0066] 4(d), which is a schematic perspective view of the vicinity of the spare seedling platform 200 of a rice transplanter according to a modified embodiment of the present invention, long rails of the spare seedling platform 200 are provided in the left-right direction at the front and rear of the machine body, and the long seedling rails are placed on these rails and moved left and right, and the seedling rails arranged in two horizontal rows can be separated into spare seedling platform parts 641 and 642, one row at a time. At this time, the seedling rails that form a single row can be easily removed from the rails, and further, the two seedling rails in one row can be arranged overlapping each other with a gap between them.

[0067] As a result, in cases where arranging the machines in two horizontal rows makes it difficult to use the row farthest from the operator, they can be stacked and both rows placed closer to the front. The rows can be freely combined to suit the operator's preferences and ease of use, resulting in an effective configuration that suits the work environment.

[0068] As shown in Figure 5(a), which is a schematic plan view (part 2) of a rice transplanter according to a modified embodiment of the present invention, long rails of a spare seedling loading platform 200 are provided in the left-right direction at the front and rear of the machine body, and a seedling rail that is long from front to back is placed on this rail and moved left and right. In this configuration, rollers of a spare seedling loading platform drive unit 651 are fixed to the back side of the seedling rail and placed on the rail, and a motor of the spare seedling loading platform drive unit 651 is attached to the rollers, and the rollers are driven electrically so that the entire seedling rail automatically moves left and right on the rail.

[0069] This makes it possible to automatically move the seedling rail to the front of the seedling tank for the row where seedlings are to be replenished, reducing the labor required for work. It is also one of the configurations for automating seedling replenishment, and can be used for robotic rice transplanters, etc.

[0070] As shown in Figure 5(b), which is a schematic front view of the vicinity of the spare seedling loading platform 200 of a rice transplanter in a modified embodiment of the present invention, long rails are provided in the left-right direction at the front and rear of the machine, and a long seedling rail is placed on this rail and moved left and right. In this configuration, a roller and a motor are fixed to the back of the seedling rail so that the entire seedling rail moves automatically left and right on the rail electrically. The motor can be either the front rail section roller or the rear rail section roller, but it is preferably attached to both so that the motor always moves in the same way.

[0071] This allows the seedling rail to move smoothly parallel to the machine body and the seedling tank, resulting in a stable and reliable operating configuration. It also prevents problems such as the seedling rail becoming slanted and derailing from the rail, or the auxiliary seedlings being placed at an angle when being sent to the seedling tank.

[0072] As shown in Figure 5(a), in a configuration in which long rails are provided in the left-right direction at the front and rear of the machine body, and long seedling rails are placed on these rails and moved left and right, rollers and a motor are fixed to the back side of the seedling rails so that the entire seedling rails can be moved automatically left and right on the rails electrically, spare seedling loading platform switches 652 are attached to the horizontal two-row integrated seedling rails so that they stop in front of the seedling tank in the planting section every third row, and the moving seedling rails stop when the spare seedling loading platform switch 652 is pressed. Here, it is assumed that the position of the seedling tank in the planting section will be determined in advance, such as in the center or at both the left and right ends.

[0073] This allows the seedling rail that has moved laterally to be stopped in front of the seedling tank of the row where seedlings are to be replenished, reducing the labor required. It also becomes one of the configurations for automating seedling replenishment, and can be used in robotic rice transplanters, etc. In addition, the spare seedling loading platform switch 652 can be configured on either the front rail section or the rear rail section only, but by attaching it to both, the seedling rail can be reliably stopped parallel to the seedling tank, resulting in an even more stable configuration. The spare seedling loading platform switch 652 is provided in three places for 6 rows and four places for 8 rows.

[0074] As shown in Fig. 5(c), which is a schematic left side view (part 2) of a rice transplanter according to a modified embodiment of the present invention, long rails are provided in the left and right direction at the front and rear of the machine body, rollers and motors are fixed to the long seedling rails in the front and rear, and the entire seedling rail is automatically moved left and right on the rails by electric power, and the seedling rail is configured to be tilted backward and downward from the horizontal. The fulcrums for tilting in the up and down rotation directions shown by the arrows are the rear left and right rails, and a spare seedling placement platform rotation part 661 is provided between the rollers placed on the rear left and right rails and the seedling rails to connect them.

[0075] This allows the seedling rail to be tilted backwards so that the auxiliary seedlings can be sent backwards under their own weight. The tilting configuration reduces the number of parts and is advantageous in terms of cost, without the need to provide a long belt or multiple belts across the entire seedling rail. In addition, by providing the rotation fulcrum of the spare seedling loading platform rotating part 661 on the roller part behind the seedling rail, the roller can tilt the seedling rail without changing the inclination relative to the left and right rear rails, and a configuration can be achieved in which the rollers are not subjected to excessive load or come off the rails.

[0076] As shown in Figure 5(c), long rails are provided in the left-right direction at the front and rear of the machine, and rollers and a motor are fixed to the long seedling rails in the front-rear direction, so that the entire seedling rail can be automatically moved left and right on the rails by electric power, and the seedling rail can be tilted from horizontal to downward toward the rear. In this case, spare seedling loading platform rotating cylinders 662 are provided on the front left and right rails, and the front of the seedling rail is raised and lowered by the expansion and contraction of the spare seedling loading platform rotating cylinders 662, so that the entire seedling rail can be tilted. The spare seedling loading platform rotating cylinders 662 are provided between the rollers placed on the front left and right rails and the seedling rail in the up-down direction, connecting them.

[0077] This allows for a configuration that can lift and tilt even heavy seedling rails with auxiliary seedlings on them. When six rows of six auxiliary seedlings are placed on the seedling rail, a seedling rail weighing more than 40 kg must be lifted, but this is possible by using hydraulics, and by allocating some of the load on the electrical components to the hydraulics in an automated seedling supply configuration that uses many motors, it is possible to configure the system without having to make the batteries, generators, motors, wires, etc. significantly larger than before.

[0078] Further, a modified embodiment of the present invention will be described.

[0079] A seedling fence member 300 that can be opened and closed in the front-rear direction of the vehicle body is provided at the rear end of the spare seedling loading platform 200. When the seedlings are loaded from the rear end of the spare seedling loading platform 200 to the seedling loading device 80 by sliding movement, the seedling fence member 300 is opened to guide the seedlings.

[0080] A more specific explanation is as follows.

[0081] As shown in Fig. 5(d) and 5(e), which are schematic left side views (parts 1 and 2) of the vicinity of the seedling loading device 80 of the rice transplanter according to the embodiment of the modified example of the present invention, long rails are provided in the left and right direction at the front and rear of the machine body, rollers and motors are fixed to the long seedling rail in the front and rear, and the entire seedling rail moves automatically left and right on the rail by electric power. In this configuration, the fence of the seedling fence member 300 at the rear end of the seedling rail can be opened and closed, and when the rear end fence is opened while the seedling rail is in a horizontal state, the upper end of the seedling tank of the seedling loading device 80 at the highest planting section and the rear end of the seedling rail are connected by the fence surface. In this case, when the entire seedling rail is tilted to lower the rear end downward, the fence opened to the rear is automatically lifted upward by the stopper plate 663 provided below the rear end of the seedling rail. The stopper plate 663 is fixed to the lower part of the seedling rail rotation fulcrum of the spare seedling loading platform rotating part 661 provided on the rear left and right rail parts, and is configured so that the stopper plate 663 does not move even if the seedling rail is tilted. Only auxiliary seedlings are to be placed on this seedling rail after they have been removed from the seedling box.

[0082] This allows the rear end fence of the seedling rail of the seedling fence member 300 to be automatically opened and closed, and also automatically connected to the seedling tank of the seedling loading device 80, allowing auxiliary seedlings to be sent in directly, leading to reduced labor. It also becomes one of the seedling supply automation configurations, and can be used for robotic rice transplanters, etc. In addition, since the seedling rail is tilted to send auxiliary seedlings backward, a rear end fence is provided when tilted, making it possible to pack auxiliary seedlings in from the rear end of the seedling rail, improving workability.

[0083] Further, a modified embodiment of the present invention will be described.

[0084] Near the rear end of the spare seedling loading platform 200, there is provided a seedling transport belt member 400 for transporting the seedlings when they are slid from the rear end of the spare seedling loading platform 200 to the seedling loading device 80.

[0085] A more specific explanation is as follows.

[0086] As shown in Fig. 5(f), which is a schematic left side view (part 3) of the vicinity of the seedling loading device 80 of the rice transplanter of the modified embodiment of the present invention, long rails are provided in the left and right direction at the front and rear of the machine body, rollers and motors are fixed to the long seedling rails in the front and rear, and the entire seedling rails are automatically moved left and right on the rails by electric power. In this configuration, the seedling feed belt of the seedling feed belt member 400 for feeding the auxiliary seedlings backward, shown by the dashed rectangle, is provided only behind the seedling rail. This belt is provided at a length of about 1 / 3 to 1 / 2 of the auxiliary seedlings from the front of the rear end fence, and is driven by the seedling feed belt motor 671. No seedling feed belt is provided further forward than this, but a spare seedling loading platform roller unit 653 with a simple roller for sliding the seedlings may be provided.

[0087] As a result, one auxiliary seedling at the rear of the seedling rail can be automatically sent rearward by this seedling feed belt, and when connected to the seedling tank in the planting section, the auxiliary seedling can be slid directly into the seedling tank, making it one possible configuration for automating seedling supply and suitable for use in robotic rice transplanters, etc.

[0088] Further, a modified embodiment of the present invention will be described.

[0089] When seedlings are loaded from the front end of the spare seedling stand 200, the inclination of the spare seedling stand 200 is adjusted so that the height of the front end of the spare seedling stand 200 substantially coincides with the height of the rear end of the spare seedling stand 200.

[0090] Seedlings can be easily put into the seedling tank, and seedlings can be replenished into the tank even from outside the machine.

[0091] Of course, the support frames of the spare seedling loading platform 200 are located at the front and rear of the machine body, and at least one of the front and rear can move up and down, with the front side having a larger range of upward movement, so that the seedlings can be placed into the seedling tank with a front-upward incline.

[0092] A more specific explanation is as follows.

[0093] As shown in FIG. 5(c), long rails of the spare seedling stand 200 are provided in the left and right directions in front and behind the machine body, rollers and motors are fixed to the long seedling rails in the front and rear directions, and the entire seedling rails are automatically moved left and right on the rails by electric power. In this configuration, the process of fully automatically supplying seedlings to the seedling tank in the planting section is as follows. During normal planting work, the seedling rail is in a tilted position and receives auxiliary seedlings from the rear fence, and work is performed with the auxiliary seedlings lined up from the rear. When a row that needs seedling supply is generated by the seedling tank seedling run-out switch, the tilted seedling rail moves sideways in front of the seedling tank of that row and stops. The planting work continues, and when the seedling tank reaches a predetermined position (center or left or right end, etc.), the planting work is stopped, the machine stops, and the planting section rises. At the same time, the tilted seedling rail changes its position so that it is horizontal, and the rear end fence opens and connects to the seedling tank. Then, the seedling feed belt of the seedling rail is driven to send the auxiliary seedlings to the seedling tank. After that, when the seedling tank seedling shortage switch is pressed by the newly replenished auxiliary seedlings, the seedling rail returns to its tilted position again, and the auxiliary seedlings in front slide backwards, lining up closer together than in the rear. Then the planting work begins again.

[0094] This allows the system to automatically replenish seedlings when the seedling tank runs out of seedlings. This automated seedling replenishment system can be used for robotic rice transplanters, etc.

[0095] As shown in Figure 5(a), a long rail of the spare seedling loading platform 200 is provided in the left and right direction at the front and rear of the machine body, and rollers and motors are fixed to the long seedling rails in the front and rear, so that the entire seedling rail moves automatically left and right on the rails. In this configuration, if seedlings run out in two or more places or in two or more rows at the same time during the process of fully automatic seedling supply to the seedling tank in the planting section, seedlings are supplied in order from the left row. In cases other than the combination of two rows where the seedling rails in two horizontal rows stop (1-2, 3-4, 5-6 for six rows), seedlings cannot be supplied at once, so after the seedling supply at the first location is completed and the seedling rail takes an oblique position, it moves horizontally to the second seedling supply position, and the seedling rail takes a horizontal position again to supply seedlings. In this case, the planting section does not need to descend.

[0096] This allows the system to automatically replenish seedlings in order, even if multiple rows run out of seedlings at the same time. This can be done with the planting section in the highest position, allowing for smooth, fully automatic seedling replenishment. This system can be used for robotic rice transplanters, etc., as an automated seedling replenishment system.

[0097] As shown in Figure 5(a), long rails are provided in the left-right direction at the front and rear of the machine body, and rollers and motors are fixed to the long seedling rail from front to back, so that the entire seedling rail automatically moves left and right on the rail electrically. When seedlings are supplied to the seedling tank in the planting section fully automatically, the seedling rail is configured to supply auxiliary seedlings to the seedling tank in a horizontal position, and the seedling supply belt of the seedling supply belt member 400 provided on the seedling rail is designed to only wrap around one auxiliary seedling shown in the dashed rectangle at the rear, so that seedlings in front of the seedling rail are not supplied continuously, and only one auxiliary seedling can be sent at a time.

[0098] This ensures that when seedlings are replenished automatically based on the seedling tank seedling shortage switch, one auxiliary seedling will not be sent from the seedling rail to the seedling tank, slide down the seedling tank, and the next auxiliary seedling will not be sent in succession before the seedling tank seedling shortage switch is pressed, and there will be no malfunctions such as auxiliary seedlings that do not fit in the seedling tank being sent, or the seedling rail changing position while an auxiliary seedling is still halfway between the seedling rail and the seedling tank. Also, there is no need to provide an extra switch to check the presence or absence of auxiliary seedlings other than the seedling tank seedling shortage switch, which is advantageous in terms of cost.

[0099] As shown in Figure 5(a), long rails are provided in the left-right direction at the front and rear of the machine, and rollers and motors are fixed to the long front-rear seedling rail, so that the entire seedling rail automatically moves left and right on the rail electrically. In addition to the length of three auxiliary seedlings shown in the dashed rectangle, the entire length of the seedling rail is extended forward by the length of the seedling feed belt of the seedling feed belt member 400 provided at the rear. Also, when seedlings are supplied to the rail from the ridge, the rail is placed in a horizontal position so that the front can be lowered.

[0100] As a result, when seedlings are fed from the ridge to the horizontally positioned seedling rail, the auxiliary seedlings are continuously pushed from the front to the rear, and even if they get stopped by the bumps on the seedling feed belt, three auxiliary seedlings can be loaded without protruding from the front of the seedling rail, eliminating the need to force the auxiliary seedlings into the seedling rail, which also eliminates problems such as the auxiliary seedlings being damaged, improving workability. Auxiliary seedlings that have not been fed to the rear end of the seedling rail will slide down to the rear end under their own weight after the seedling rail is tilted, so there is no problem.

[0101] As shown in Figure 5(a), long rails are provided in the left-right direction at the front and rear of the body, and rollers and a motor are fixed to the long seedling rail from front to back, so that the entire seedling rail automatically moves left and right on the rail electrically. The seedling feed belt of the seedling feed belt member 400 provided at the rear of the seedling rail and the seedling feed belt motor 671 which drives it are provided independently for each row of the seedling rail which is formed into two horizontal rows, so that the seedling feed belt can be driven even on only one side.

[0102] As a result, even in cases where there is only one row of seedling tank that requires seedling supply, or in cases where the rice transplanter has an odd number of rows, it is possible to supply seedlings by moving only one row of seedling feed belts on a seedling rail that is integrated into two horizontal rows, making it possible to create a configuration that is compatible with fully automatic seedling supply.

[0103] As shown in Figure 5(a), long rails are provided in the left-right direction at the front and rear of the body, and rollers and a motor are fixed to the long seedling rail in the front-to-rear direction, so that the entire seedling rail automatically moves left and right on the rail electrically. In this configuration, a seedling cut-off switch 681 is provided just before the rear end fence of the seedling rail of the seedling fence member 300.

[0104] As a result, without this seedling out switch 681, when the seedling tank seedling out switch determines that the seedlings are out during planting work, the automatic seedling supply movement will begin even if there are no auxiliary seedlings on the seedling rail, and the seedling feed belt of the seedling rail will be driven and it will take time to determine that there are no auxiliary seedlings on the seedling rail until a certain amount of time has passed without seedlings being supplied, but it can now determine that there are no auxiliary seedlings on the seedling rail without waiting for this time, and it is possible to make a decision to make a different movement or issue a signal in a short time without making any unnecessary movements when the seedling tank is out of seedlings. This configuration can be used for robotic rice transplanters, etc. as a seedling supply automation configuration.

[0105] Further, a modified embodiment of the present invention will be described.

[0106] The seat 51 is a seat on which an operator sits. The fertilizer application device 70 is disposed below the seat 51. The engine 20 is disposed in front of the seat 51. The fertilizer application device 70 has a fertilizer blower 500 having an intake port 510 provided in the vicinity of the engine 20.

[0107] A more specific explanation is as follows.

[0108] As shown in Fig. 6(a), which is a schematic plan view (part 3) of a rice transplanter according to a modified embodiment of the present invention, the fertilizer applicator 70 is disposed in the position where the mid-engine was conventionally disposed, below the center of the vehicle body and below the seat 51. The engine 20 is disposed inside the front bonnet, forming a front engine configuration.

[0109] As a result, the mid-fertilizer applicator that was previously located in front of the planting section is no longer present, and the space above the rear step of the machine is wider, making it easier for the operator to supply seedlings to the planting section. In addition, the fertilizer applicator is placed in a lower position forward than in conventional mid-fertilizer applicators, and the engine 20 is placed at the front, so the balance of the machine is forward-balanced, improving the so-called wet-field performance.

[0110] As shown in Fig. 6(a), in a configuration in which the fertilizer applicator is located below the center of the machine body, the fertilizer capsules of the fertilizer capsule unit 710 are arranged vertically in two rows. The fertilizer hopper of the fertilizer hopper unit 720 is composed of one large hopper above all of the capsules arranged in two rows.

[0111] This makes it possible to configure and arrange the fertilizer applicator vertically between the conventional mid-engine arrangement in the center of the aircraft and the rear wheels 32.

[0112] As shown in Figure 6(a), in a configuration in which the fertilizer applicator is located below the center of the machine body, the fertilizer blower 500 is located in front of the fertilizer applicator, an air chamber 730 is located between two rows of capsules, and air is sent from an air intake duct 740 to the bottom of each of the left and right rows of capsules. The fertilizer hose of the fertilizer hose unit 750 is routed from the outside of the left and right sides of the capsules and connected to the planting unit.

[0113] This allows for a configuration in which air can be sent to each row of capsules arranged in two rows. In addition, the air chamber 730, which is located in the center and sends air to the capsules on both sides, can be configured at a shorter distance than the fertilizer blower 500, making it easier to send a stable amount of air to each row. Each part is also smaller, and the number of connecting parts can be reduced, which is also advantageous in terms of cost.

[0114] In a configuration in which the fertilizer applicator is located below the center of the body as shown in Figure 6(a), two walls 760 are provided on the back side of the step between engine 20, which is the front engine, and fertilizer blower 500 located in front of the fertilizer applicator, with a gap of approximately the width of engine 20 and the fertilizer applicator (or, in addition to this, a duct is extended from the blower intake port, passing under the step to the rear of the front engine).

[0115] As a result, hot air from engine 20, which is a front engine, flows rearward through walls 760 on the back surface of the step during actual operation, and the blower intake port on the front of the fertilizer applicator sucks it in, allowing the hot air to flow into air chamber 730. This arrangement of engine 20 and fertilizer applicator makes it possible to achieve a configuration that enhances the effect of heating and drying the fertilizer applicator and fertilizer using only two walls 760, without the need for a complex configuration (providing a duct would be more effective, and this arrangement requires a shorter duct).

[0116] As shown in Fig. 6(a), in a configuration in which the fertilizer applicator is disposed at the center and below the machine body, the fertilizer applicator hose of the fertilizer applicator unit 750 is configured to connect from the front capsule to the planting section of the center row, and from the rear capsule to the planting sections of both ends. That is, the first to eighth capsules are connected to the planting sections from the left to the right in order, for example, the first capsule is connected to the leftmost planting section, and the eighth capsule is connected to the rightmost planting section. The fertilizer applicator is routed from the left and right outer sides of the fertilizer applicator to the rear, passing through the inside of the rear wheels 32 along the fertilizer applicator, and connected to each row of the planting section.

[0117] This allows the length of the fertilizer hoses to be uniform across the rows, making it easier to achieve uniform air volume and speed. In addition, the fertilizer hoses can be routed in the shortest possible distance without bending significantly, making it possible to configure a stable fertilizer applicator that is less likely to clog.

[0118] As shown in Fig. 6(b), which is a schematic left side view (part 3) of a rice transplanter according to a modified embodiment of the present invention, and Fig. 6(c), which is a schematic front view (part 1) of the vicinity of the fertilizer applicator 70 of a rice transplanter according to a modified embodiment of the present invention, in a configuration in which the fertilizer applicator is arranged at the lower center of the machine body, the fertilizer hopper of the fertilizer hopper section 720 is made of a sturdy material and is configured so that it will not break even if an operator stands on the fertilizer hopper cover 721 at the top of the hopper. The fertilizer hopper is arranged so as to be embedded at the lower center of the machine body, and no cover is provided on the top or sides, and the fertilizer hopper itself is configured to serve as a step. Fertilizer capsule mudguard covers 711 are provided only on the left and right sides of the fertilizer capsule.

[0119] This makes the fertilizer hopper itself a step, eliminating the need for a dedicated step or cover, which is advantageous in terms of cost. When opening the fertilizer hopper lid 721 on the top of the fertilizer hopper, there is no need for a double cover, improving workability.

[0120] As shown in Fig. 6(b), in a configuration in which the fertilizer applicator is disposed below the center of the machine body, the cover of the fertilizer blower 500 is provided only to surround the front blower part of the fertilizer applicator. This cover is only provided on the front, left and right sides, and top, and the rear fertilizer side is left open.

[0121] This covers the feet of the operator when he sits on the seat 51, and prevents mud from getting on the fertilizer blower 500 and the fertilizer applicator. It also serves as a guard to prevent the operator from kicking the fertilizer blower 500 with his foot. In addition, it prevents the hot air from the engine 20, which is the front engine, flowing through the space indicated by the diagonal rectangular area in the direction indicated by the arrow and into the rear blower section from directly hitting the operator, improving the working environment, and is also thought to have the effect of storing hot air inside the cover and discharging it to the rear. Furthermore, since it is only a partial cover, it does not impair the maintainability of the fertilizer applicator and improves the appearance of the machine.

[0122] In a configuration in which the fertilizer applicator is positioned below and in the center of the machine body as shown in Figure 6(b), the fertilizer hopper lid 721 is hinged at the front of the hopper and configured to rotate in the direction indicated by the arrow and open from the rear to the front without interfering with the seat 51 or the like.

[0123] This allows fertilizer to be added from any of the three directions (left, right, and rear), making it easy to work with. In addition, because a high rear step is provided at the rear of the machine, when adding fertilizer from the left, right, rear, or rear of the fertilizer applicator, the heavy fertilizer bag can be placed on the rear step and tilted to add fertilizer, which reduces the amount of work required. Furthermore, by opening the fertilizer hopper lid 721 forward, the fertilizer hopper lid 721 can prevent fertilizer from spilling forward, so the fertilizer blower 500, seat 51, or bonnet located at the front are less likely to get dirty or rusty.

[0124] 6(d), which is a schematic plan view of the vicinity of the fertilizer applicator 70 of a rice transplanter according to an embodiment of a variation of the present invention, in a configuration in which the fertilizer applicator is disposed below the center of the machine body, the fertilizer discharge duct section 770 for the remaining fertilizer is connected to the rear end of the air chamber provided between the capsules in the center of the fertilizer applicator, the duct is split into two at the rear end of the fertilizer applicator, bent 180° toward the outside of the left and right capsules, and extended forward along the outside of the left and right capsules. The end is bent 90° from the front of the fertilizer applicator toward the outside of the machine body, and the duct is discharged from below the step, between the front and rear wheels, and discharged from there.

[0125] This allows the remaining fertilizer to be discharged in the direction indicated by the arrow even from the fertilizer applicator embedded in the center of the machine. In addition, by connecting a duct to the extension of the air chamber 730, it is possible to configure it without the need to switch the air path, which is also advantageous in terms of cost. Since air is always leaking into the fertilizer hose side when air is discharged, the air volume decreases and the discharge speed becomes slow, but by dividing it into left and right and discharging half at a time, the amount of discharge at one time can be reduced, and it can be discharged smoothly without clogging problems.

[0126] As shown in Fig. 6(e), which is a schematic front view (part 2) of the vicinity of the fertilizer applicator 70 of a rice transplanter according to a modified embodiment of the present invention, in a configuration in which the fertilizer applicator is located at the center and below the machine body, two rows of fertilizer capsules are arranged on the left and right, and a drive shaft is provided for each row. Gears are attached to the two shafts at the front of the fertilizer applicator, and two gears are sandwiched between them to transmit the driving force in the left and right directions as indicated by the arrows. The driving force is taken from the output part of the transmission case 780 at the front of the machine body, and the rotating shaft is extended rearward from here, and the rotational motion is converted into oscillation and transmitted to one of the four gears by a rod 781 that functions as an input arm, to drive the machine.

[0127] This results in a configuration that allows the fertilizer applicators arranged in two rows in the center of the machine to be driven. In addition, since the fertilizer applicators are located close to the transmission case 780, the driving force can be easily extracted from there with a simple configuration, and it is easy to set up a configuration in which the fertilizer applicators are driven by the PTO as well, which improves workability and is also advantageous in terms of cost.

[0128] (A) Furthermore, a modified embodiment of the present invention relating to a fertilizer applicator 70 having a left and right independent fertilizer applicator moving mechanism will be described.

[0129] As shown in Figure 7(a), which is a schematic plan view (part 4) of a rice transplanter according to a modified embodiment of the present invention, and Figure 7(b), which is a schematic left side view (part 4) of a rice transplanter according to a modified embodiment of the present invention, the mid-fertilizer applicator of the fertilizer application device 70 is configured as left and right halves that are independent units (for example, 3 rows for 6 rows and 4 rows for 8 rows), and the fertilizer application unit moving mechanism 850 is configured so that each of the left and right units can be moved as a whole to the left and right of the front of the rice transplanter body in the directions indicated by the arrows.

[0130] This allows the fertilizer hopper to be moved to the front of the machine, so fertilizer can be added directly to the fertilizer hopper from the ridges. This eliminates the need for the operator to carry heavy fertilizer bags over the rice transplanter to add fertilizer, reducing the amount of work required.

[0131] As shown in Figure 7(c), which is a schematic front view (part 3) of the vicinity of fertilizer application device 70 of a rice transplanter in an embodiment of a modified example of the present invention, in a configuration in which the mid-fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right sides of the machine body, the left and right fertilizer applicator is configured so that, from the fertilizer frame, a hopper mechanism 810, an air chamber mechanism 820, a blower mechanism 830, a drive unit, and a residual fertilizer discharge mechanism are also provided on each side, so that the left and right fertilizer applicators are independent from each other (the drive unit can be easily separated if it is driven by a motor).

[0132] This eliminates the need to connect the left and right fertilizer applicators at the fertilizing position, and because each unit is completely independent, it is easy to move the left and right fertilizer applicators separately. This allows for an easy-to-use unit movement configuration that minimizes the need to disconnect and connect each part.

[0133] As shown in Figures 7(d) and 7(e), which are schematic left side views (parts 1 and 2) of the vicinity of the fertilizer 70 of a rice transplanter according to an embodiment of a modified example of the present invention, in a configuration in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right of the machine body, when the entire fertilizer applicator unit is moved, it is configured to be separated between the funnel 841 and the fertilizer hose in the direction indicated by the arrow. At this time, the fertilizer hose is firmly fixed at a specified position on the rice transplanter side, and a packing 842 is provided at the connection part with the funnel 841. When returning the fertilizer applicator unit to the fertilization work position, the fertilizer applicator unit is moved backward from the front of the fixed fertilizer hose, and the end of the funnel 841 is pressed against the packing 842 in front of the fertilizer hose to connect them.

[0134] This allows the fertilizer hose, the only part that must be disconnected when moving the fertilizer applicator unit, to be connected with a single touch, improving workability.

[0135] As shown in FIG. 8(a) which is a schematic plan view (part 1) of the vicinity of the fertilizer unit moving mechanism 850 of the rice transplanter according to the embodiment of the modified example of the present invention, and FIG. 8(b) which is a schematic left side view (part 1) of the vicinity of the fertilizer unit moving mechanism 850 of the rice transplanter according to the embodiment of the modified example of the present invention, in the first unit movement method in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right of the machine body, the unit is moved by providing a fertilizer unit movement rotation fulcrum part 851 for rotating the unit horizontally on the outside left and right of the fertilizer applicator, and rotating the unit 90° toward the front of the machine body in the direction indicated by the arrow with the fulcrum. The vertically oriented unit slides and moves toward the front of the machine body in the direction indicated by the arrow on the roller provided at the bottom of the rotation fulcrum and the rail of the fertilizer unit moving mechanism 850 extending forward and backward. At this time, the operator holds the side of the unit opposite to the fertilizer unit movement rotation fulcrum part 851, and always moves it in a cantilevered state.

[0136] This allows the fertilizer applicator unit to be easily moved to the front of the machine. In addition, the work of moving the unit to the front of the machine can be done within the range of the machine's steps and side steps, making it easy to work with. Furthermore, because the unit is oriented vertically at the front of the machine, the fertilizer hopper faces in a direction that makes it easy to put fertilizer in from the front step of the machine, even if the ridge is low, making it easy to work with. In addition, the rails that extend forward and backward can be made short without extending to the front of the machine, so the rails do not get in the way of the machine's turning even during actual work with the fertilizer applicator at the rear, making it easy to work with.

[0137] As shown in Fig. 8(b), in the first unit movement method in which the mid fertilizer applicator is divided into two halves, left and right, and the entire unit is moved to the front left and right of the machine body, the fertilizer applicator unit is rotated horizontally by 90° around the left and right outer sides as fulcrums, and when it is slid forward from there along the rails of the fertilizer applicator unit moving mechanism 850, the rails extending forward and backward are configured to bend downward in a crank shape in the direction indicated by the arrow. In addition, the rails are shaped so as not to protrude above the shape of the step when viewed from the side.

[0138] This allows the fertilizer applicator unit to be moved forward at a lower height than the fertilizer application position at the rear of the machine, making it easier to supply fertilizer and improving workability. Also, because the rails do not protrude beyond the shape of the step when viewed from the side, the rails do not get in the way of the operator's movements even when the fertilizer applicator is at the rear of the machine, improving workability. For machines with side steps, the rails are hidden inside them, so they do not affect the operator's movements.

[0139] As shown in Figures 8(c) and 8(d), which are schematic front views (parts 1 and 2) of the vicinity of a fertilizer unit moving mechanism 850 of a rice transplanter in an embodiment of a modified example of the present invention, in a first unit movement method in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right sides of the machine body, the fertilizer applicator unit is rotated horizontally 90° around the left and right outer sides as fulcrums, and then slid forward along the rails, a handle portion 852 is provided on the upper side opposite the fertilizer unit movement rotation fulcrum portion 851 of the fertilizer applicator unit.

[0140] This allows the operator to hold this part when moving the fertilizer applicator unit forward, making it easier to work. Also, when the unit is moved to the front of the machine body, this handle part 852 is located at the front end of the machine body, which also serves as a handrail for the operator to get on and off the machine from the front, improving workability.

[0141] As shown in Fig. 9(a) which is a schematic plan view (part 2) of the vicinity of the fertilizer unit moving mechanism 850 of the rice transplanter of the embodiment of the modified example of the present invention, Fig. 9(b) which is a schematic left side view (part 2) of the vicinity of the fertilizer unit moving mechanism 850 of the rice transplanter of the embodiment of the modified example of the present invention, and Fig. 9(c) which is a schematic perspective view of the vicinity of the fertilizer unit moving mechanism 850 of the rice transplanter of the embodiment of the modified example of the present invention, in the second unit movement method in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right of the machine body, the movement method is as follows: first, the left and right rails of the fertilizer unit moving mechanism 850 are arranged at the bottom of the unit, and the unit is configured to be slid to the outside of the machine body in the direction indicated by the arrow. At this time, the unit is made to be able to slide to the outside of the machine body to a position that avoids the bonnet and engine cover when viewed from the front, and the rails are arranged in a position that does not overlap with the bonnet and engine cover when viewed from the front. Next, a rail in the forward / backward direction is placed on the outside of the aircraft, and the unit is slid to the outside of the aircraft using this rail, and can be slid and moved to the front of the aircraft in the direction indicated by the arrow (the detailed configuration of the rail can be any configuration).

[0142] This allows the fertilizer applicator unit to be moved to the left and right front of the machine body by sliding only without lifting it, and the operator does not need to use force, but can move it just by pushing it, which reduces the labor required. Also, since the unit can be moved to the left and right front of the machine body without changing its orientation, fertilizer can be supplied from the ridge to the left and right front of the machine body, and the fertilizer hopper lid 721 also opens from front to back in the same way as shown by the arrow, making it easy to work with.

[0143] As shown in Fig. 10(a) which is a schematic plan view of a fertilizer applicator 860 with tires for a rice planter according to a modified embodiment of the present invention, Fig. 10(b) which is a schematic left side view of a fertilizer applicator 860 with tires for a rice planter according to a modified embodiment of the present invention, and Fig. 10(c) which is a schematic front view of a fertilizer applicator 860 with tires for a rice planter according to a modified embodiment of the present invention, in a third unit movement method in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right of the machine body, tires are attached to the lower part of the fertilizer applicator 860 with tires, which are independent left and right fertilizer applicators. Four tires of the tire section 861 are arranged on each fertilizer applicator, arranged front to back, left to right, to form a rectangle.

[0144] This allows the fertilizer applicator unit to be freely rolled on the tires, allowing it to be moved to any desired location to supply fertilizer. Also, the unit can be easily removed from the machine because it becomes completely independent by removing the electrical harness with a coupler, improving workability when cleaning or fertilizing work is not required.

[0145] As shown in Fig. 10(d), which is a schematic plan view (part 1) of the vicinity of the step floor 53 of the rice transplanter of the embodiment of the modified example of the present invention, and Fig. 10(e), which is a schematic left side view of the vicinity of the step floor 53 of the rice transplanter of the embodiment of the modified example of the present invention, in the third unit movement method in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right of the machine body, grooves are made on the machine body steps of the step floor 53, and the tires installed under the unit are placed in these grooves and rolled. The grooves of the tire groove portion 862 are provided in the left and right directions from the rear fertilizer application position of the machine body, and are provided in the front and rear directions from there to the outer side step portion of the step. The part connecting the left and right directions to the front and rear directions is connected by the radius (also called R) of the large arc-shaped round corner part.

[0146] This allows the fertilizer unit with tires to be moved smoothly to the left and right front of the machine body along the grooves of the tire groove portion 862 in the direction indicated by the arrow, improving workability. In addition, since the grooves on the steps are used as rails, there is no need to provide extra parts, which is also advantageous in terms of cost.

[0147] As shown in Fig. 10(f), which is a schematic plan view (part 2) of the vicinity of the step floor 53 of the rice transplanter according to the embodiment of the modified example of the present invention, in the third unit movement method in which the mid-fertilizer applicator is divided into two halves, left and right, and the entire unit is moved to the front left and right of the machine body, grooves are made on the machine body steps of the step floor 53, and the tires installed under the unit are inserted and rolled in these grooves. The grooves of the tire groove section 862 are provided in the left and right directions from the fertilization position at the rear of the machine body, and are provided in the front and rear directions on the outside of the step. Here, the left and right grooves and the front and rear grooves are provided so that two grooves each intersect at 90° in two places, and after the unit moves sideways from the fertilization position, it moves forward without changing the direction of the unit (it may be provided so that the grooves overlap the grooves connecting the front, rear, left and right at the round corners).

[0148] As a result, the fertilizer applicator unit with tires can be moved to the front left and right sides of the machine body without changing the orientation of the unit, so that fertilizer can be supplied in a long state from the ridge to the left and right sides at the front left and right sides of the machine body, and furthermore, the fertilizer hopper lid 721 also opens in the same way from the front to the back, improving workability (if the fertilizer hopper lid 721 is installed overlapping with the groove connected by the rounded corners, the unit can be moved to the front left and right sides of the machine body each time in an orientation that is easy to use depending on the work environment and conditions, improving workability).

[0149] As shown in Figure 8(d), in a configuration in which the mid fertilizer applicator is divided into two halves, left and right, and the entire unit is moved to the front left and right of the machine body, when the remaining fertilizer is discharged after moving it to the front of the machine body, in the first unit movement method, the rollers are made spherical, so that the unit can not only move forward and backward, but can also be rotated 180 degrees up and down in the direction indicated by the arrow and turned upside down, tilting the fertilizer hopper to discharge it. In addition, in the third unit movement method, since the unit is not fixed, the unit is lifted up and tilted to discharge it.

[0150] This eliminates the need for a complicated residual fertilizer discharge structure, which is advantageous in terms of cost. Also, by turning the device upside down, the remaining fertilizer can be discharged very quickly, making it easy to work with. Furthermore, by turning the device upside down, the fertilizer can be discharged without remaining in the capsule or roll, making cleaning easier.

[0151] As shown in Fig. 11(a) which is a schematic plan view of a fertilizer applicator 870 with an upper surface frame of a rice planter according to a modified embodiment of the present invention, Fig. 11(b) which is a schematic left side view of a fertilizer applicator 870 with an upper surface frame of a rice planter according to a modified embodiment of the present invention, and Fig. 11(c) which is a schematic front view of a fertilizer applicator 870 with an upper surface frame of a rice planter according to a modified embodiment of the present invention, in a configuration in which the mid fertilizer applicator is divided into left and right halves and the entire unit is moved to the front left and right of the machine body, a frame is provided as an upper surface frame 871 on which seedling boxes can be placed on the upper surface of the fertilizer hopper of the fertilizer applicator 870 with an upper surface frame. The number of frames is set to the number of rows of the fertilizer unit, and the fertilizer hopper body and the fertilizer hopper lid 721 are configured so that there is no problem in terms of strength even if seedling boxes are placed on them for the number of rows.

[0152] This allows the fertilizer unit to be moved, and the auxiliary seedlings can be loaded at the front of the machine and carried to the rear of the machine, making it easier to line them up in front of the seedling tank in the planting section, improving workability and reducing the labor required for seedling supply. In addition, there is no need to install an auxiliary seedling frame as a sub-seedling tank, which is also advantageous in terms of cost.

[0153] As shown in Fig. 11(d) which is a schematic perspective view of a fertilizer applicator 870 with an upper frame of a rice transplanter according to a modified embodiment of the present invention, and Fig. 11(e) which is a schematic left side view of the vicinity of the fertilizer applicator 870 with an upper frame of a rice transplanter according to a modified embodiment of the present invention, the mid fertilizer applicator is divided into two halves, left and right, and the entire unit is moved to the front left and right of the machine body, and an upper frame 871 is provided on the upper surface of the fertilizer hopper on which seedlings can be placed. Here, the upper surface of the fertilizer hopper is inclined so that the rear is higher and the front is lower at the fertilization position, and the frame for placing the seedlings is surrounded on three sides, and the higher rear side is left open. The seedlings taken out of the seedling box are placed in this frame at the front left and right of the machine body, and the frame is moved to the fertilization position at the rear of the machine body, and when the front side is lifted in the direction indicated by the arrow to open the fertilizer hopper lid 721, the entire frame is inclined inversely so that the rear side is lower, and the seedlings are poured directly into the seedling tank of the seedling loading device 80 from the open rear side.

[0154] This allows the fertilizer unit to be moved and auxiliary seedlings to be loaded at the front of the machine by placing them on the upper frame 871 and then transported to the rear of the machine, reducing the labor required for seedling supply work. In addition, seedling boxes do not need to be loaded on the machine, and the operator can supply seedlings simply by tilting the fertilizer hopper lid 721 on the machine, improving workability. In addition to auxiliary seedling frames, there is no need for a place to store empty boxes, which is also advantageous in terms of cost.

[0155] (B) Furthermore, a modified embodiment of the present invention relating to a fertilizer application device 70 having a lift-type sub-hopper mechanism will be described.

[0156] As shown in Fig. 12(a) which is a schematic plan view (part 5) of a rice transplanter according to an embodiment of a modified example of the present invention, and Fig. 12(b) which is a schematic left side view (part 5) of a rice transplanter according to an embodiment of a modified example of the present invention, sub-hoppers 910 are provided on the left and right sides of the front of the machine body. The sub-hopper 910 is provided at a position higher than the mid-fertilizer applicator hopper 950 above the machine body, and the sub-hopper 910 and the mid-fertilizer applicator hopper 950 are connected by a sub-hopper hose 930 that allows fertilizer to pass through.

[0157] As a result, fertilizer can be sent from the sub-hopper 910 to the mid-fertilizer applicator hopper 950, so fertilizer can be supplied by putting it in the sub-hopper 910 at the front of the machine, eliminating the need to carry heavy fertilizer bags on top of the rice transplanter, which reduces the labor required. In addition, by placing the sub-hopper 910 at the front of the machine and in a high position, it acts as a weight, improving the machine's front-to-rear balance and improving its wet-field performance.

[0158] As shown in Figure 12(c), which is a schematic front view of the vicinity of the sub-hopper 910 of a rice transplanter in a modified embodiment of the present invention, in a configuration in which the sub-hopper 910 is provided at a high position on the left and right front sides of the machine body, the sub-hopper support pillars 920 supporting the sub-hopper 910 are configured on the outside of the hopper and also on the outside of the machine body.

[0159] This allows the step space below the sub-hopper 910, which is placed at a high position, to be widely used, allowing operators to pass through or using it as space for seedling replenishment, etc., improving workability.

[0160] In a configuration in which sub-hoppers 910 are provided at high positions on the left and right front sides of the body as shown in Figure 12(b), the sub-hopper 910 has sub-hopper supports 920 made of rails or the like, so that it can be moved up and down in the up and down directions indicated by the arrows (any configuration for moving the sub-hopper up and down is acceptable).

[0161] As a result, when replenishment of fertilizer to the sub hopper 910 is performed, the sub hopper 910 can be lowered to a low position, making it possible to replenish fertilizer without having to lift a heavy fertilizer bag to a high position, thereby reducing the amount of work required.

[0162] 12(b), in a configuration in which sub-hoppers 910 are provided at high positions on the left and right sides of the front of the machine body, the sub-hopper hose 930 connecting the sub-hopper 910 and the mid-fertilizer applicator hopper 950 is connected to the rear lower end of the rear or lower surface on the sub-hopper side and to the front upper end of the front or upper surface on the mid-fertilizer applicator hopper side, and the sub-hopper 910 is positioned so that the connection with the sub-hopper hose 930 is higher on the sub-hopper side than on the mid-fertilizer applicator hopper side. In addition, the sub-hopper hose 930 connecting these is connected straight downward to the rear without bending in a side view.

[0163] This allows the fertilizer to flow from the sub hopper 910 to the mid fertilizer applicator hopper 950 by its own weight, making it possible to construct it inexpensively without the need for a configuration such as a blower to send air. Also, by lowering the sub hopper 910 to a low position, the inclination of the sub hopper hose 930 drops forward, making it possible to stop the fertilizer from flowing backward, and by doing this when the mid fertilizer applicator hopper 950 is full, it acts as a tank to hold the fertilizer auxiliary to the machine, improving the efficiency of actual work.

[0164] In a configuration as shown in Figure 12(a), where sub-hoppers 910 are provided at high positions on the left and right front sides of the body, sub-hopper hoses 930 connecting the sub-hopper 910 and the mid-fertilizer applicator hopper 950 are provided in the same number of rows, and are configured to connect each row of the mid-fertilizer applicator hopper to the left and right sub-hoppers 910, respectively.

[0165] This allows fertilizer to be spread evenly over each row of the mid-fertilizer applicator, making it easy to operate.

[0166] As shown in Figure 12(b), in a configuration in which sub-hoppers 910 are provided at high positions on the left and right sides of the front of the machine body, mid-fertilizer applicator hopper sensors 941 and 942 that can determine whether fertilizer is exhausted or full are attached to mid-fertilizer applicator hopper 950, and sub-hopper 910 automatically moves accordingly, rising up to supply fertilizer when fertilizer is exhausted and lowering down to stop supplying fertilizer when full. The up and down movement can also be operated manually.

[0167] As a result, if the sub-hopper 910 is replenished with fertilizer, fertilizer will be automatically replenished whenever the mid-fertilizer applicator hopper 950 runs out of fertilizer during actual work, improving workability. Even if the fertilizer is not out of fertilizer, fertilizer will be replenished by manually raising the sub-hopper 910, and when it becomes full, the sub-hopper 910 will automatically descend and stop fertilizer replenishment, improving workability. Because it is configured to automatically replenish fertilizer, it can also be used with robotic rice transplanters without an operator.

[0168] As shown in Figures 12(a) to 12(c), in a configuration in which sub-hoppers 910 are provided at high positions on the left and right front sides of the machine body, slope sensors (tilt sensors) that detect the front-to-rear tilt are attached to the running section, and the sub-hopper 910 is configured to automatically rise when the machine body tilts so that the front rises significantly.

[0169] As a result, by raising the sub-hopper 910, which acts as a weight, the front-to-rear balance of the machine body becomes even more balanced toward the front. Therefore, by raising the sub-hopper 910, which is normally in a low position during actual operation, even if the mid-fertilizer applicator hopper 950 has not run out of fertilizer, it is possible to prevent the front of the machine body from floating. This can be used to improve the balance in improving wet-field conditions during operation, thereby improving workability. [Industrial Applicability]
