Description

  The present invention relates to a riding type rice transplanter, and more specifically, a unit composed of a side fertilizer machine equipped with a seedling stand, a planting part and a fertilizer hopper is mounted at an intermediate position between the front and rear wheels, and forward or backward of the unit. In a mid-mount type rice transplanter with a driver's seat and an engine bonnet in the forefront, it is easy for workers to replenish spare seedlings and replenish fertilizer to the fertilizer hopper of the side fertilizer applicator. And at the time of the work, the worker can move to the shore without getting off the field.

  Conventionally, as shown in FIG. 10, in a riding rice transplanter with a mid-mounting planting part, in a two-seater type with a driver and an assistant, a driver's seat is located behind the engine bonnet 2 on the front 1 </ b> F of the fuselage 1. 3 is provided, and a unit 4 comprising a seedling mount 4a, a seedling planting machine 4b and a side-row fertilizer application machine 4c is mounted at the rear of the driver's seat 3, and a spare seedling mount 5 and an assistant seat 7 are mounted at the rearmost part 1B. is doing. In the single-seat type without the assistant seat, instead of providing a driver seat at the front of the unit, a driver seat is provided at the rear of the unit, and the auxiliary seat at the rear is eliminated and only a spare seedling platform is provided. Yes.

  In this type of mid-mount rice transplanter, a step 6 is provided on the side of the engine bonnet 2, but no step is provided for the driver to walk from the driver's seat 3 to the last part. Moreover, the step etc. which become a scaffold of an operator at the time of fertilizer supply to the fertilizer hopper of a fertilizer applicator are not provided.

  At the time of rice planting work, it is necessary for the driver to supply spare seedlings, fertilizer to the side fertilizer applicator, etc., in which case the driver descends from the rice transplanter to the shore, and reserves placed on the shore It is necessary to replenish seedlings and fertilizer, and it is necessary to return to the driver's seat after replenishment.

  As shown in FIG. 11 (A), when the rice transplanter 1 is operated and operated in the field A, as shown in FIG. 11 (B), when the machine body front portion 1F is attached to the shore, You can get off to shore G through step 6. However, in order to place the preliminary seedling from the shore G on the preliminary seedling stand 5 at the rear of the machine body, it is necessary to go down to the field A once. In addition, during the rice planting work, the work to bring the front part 1F close to the shore G is limited, and in the case of mid-mount type rice transplanter, when reserve seedling and fertilizer are replenished, it is better to bring the rear part 1B close to the shore. The work is easy to perform, and normally, as shown in FIG.

  In this case, the driver had to go down into the field A, walk in the field A, bypass the aircraft, go to the shore G, and go up to the shore. As described above, there is a problem in that workability is greatly reduced when the driver has to go down to the field and bypass the machine body every time supplementary seedlings and fertilizer are replenished.

  For this reason, there has been a strong demand to be able to replenish spare seedlings and fertilizers placed on the shore without getting off the field from the aircraft.

  In addition, in order to efficiently carry out rice planting work, it is necessary to reduce the number of times of fertilizer supply to the side fertilizer machine that is performed at the shoreline. Therefore, it is possible to increase the capacity of the fertilizer hopper and load a large amount of fertilizer at once. I am doing so. However, when the capacity of the fertilizer hopper is increased, the position of the fertilizer hopper on the upper surface side becomes higher from the ground, and the amount of fertilizer to be replenished at one time also increases. It has become.

  In particular, when a fertilizer hopper of a side fertilizer is provided in front of the planting portion in a mid-mount riding rice transplanter, the position is behind the engine bonnet in the front of the aircraft. For this reason, fertilizer cannot be replenished directly from the shore to the fertilizer hopper even if the front part of the aircraft is close to the shore. In addition, as described above, it is common to perform the aircraft after turning around the shore and bringing the rear part of the aircraft closer to the shore. In this case, the operator goes to the fertilizer hopper through the field, and the fertilizer It is necessary to replenish. Furthermore, since the fertilizer inlet of the fertilizer hopper is located at a high position, a heavy fertilizer bag must be raised in order to supply a large amount of fertilizer.

  In addition, when there are fertilizer hoppers on the left and right sides of the aircraft, it is necessary to bypass the surroundings of the aircraft. At this time, since one side of the aircraft is a field where seedlings have already been planted, care must be taken at the feet so as not to step on the seedlings, and since the fertilizer hopper has increased in capacity, a heavy fertilizer bag should be used. It is necessary to go back and forth between the shore and the fertilizer hopper mounting position many times.

  In some cases, the fertilizer hopper of the side fertilizer application machine is mounted on the upper part of the planting part. In this case, the position of the fertilizer inlet of the fertilizer hopper is higher than the case where the fertilizer hopper is arranged in front of or behind the planting part, and the fertilizer hopper has a large capacity as described above. , The slot will be even higher. Therefore, it becomes difficult to replenish fertilizer from outside the aircraft.

The present invention has been made in view of the above-described problems, and allows the driver to move to the shore without getting off the field, and reserve seedlings and fertilizers mounted on the fuselage with spare seedlings and fertilizers placed on the shore. The first task is to be able to supply the fertilizer hopper of the machine.
Furthermore, a second problem is to enable a large amount of fertilizer to be easily replenished in an easy posture to a fertilizer hopper that has a large capacity and a high fertilizer inlet.

In order to allow the driver as the first problem to move to the shore without getting off the field, the present invention is a riding type rice transplanter in which the driver's seat is arranged behind the engine bonnet at the front of the aircraft,
A riding type rice transplanter is provided that is provided with a passage through which an operator can walk from the floor of the driver's seat to the rearmost part of the aircraft.

  The passage is set to a height that is substantially equal to the height of the shore when the aircraft is close to the shore. In this way, by providing a passage from the driver's seat floor to the rearmost part of the aircraft, when the rear of the aircraft is moved closer to the shore, the driver moves on the aircraft from the driver's seat to the rear of the aircraft without getting off the field. You can get off to the shore. Therefore, it is possible to supply spare seedlings and fertilizers placed on the shore without passing through the farm field to the preliminary seedling stand on which the machine body is mounted and the fertilizer hopper of the fertilizer applicator.

In particular, in the middle position of the front and rear wheels, a unit equipped with a seedling stand, planting part and side fertilizer machine as needed is mounted in parallel in the vehicle width direction, and the driver's seat is mounted in front of it In a mid-mount type rice transplanter equipped with a farmer's seat at the rearmost part and spare seedling platforms on both sides thereof, the work efficiency is better when the rear part of the machine body is brought closer to the shore as described above. Therefore, if the driver moves from the driver's seat to the last part of the aircraft through the passage and descends to the shore so that spare seedlings and fertilizer can be supplied, the efficiency of rice planting work can be improved in the mid-mount rice transplanter. It can be improved dramatically.
In addition to rice transplanters that have a mid-mounting section, other types of rice transplanters also provide a path from the driver's seat to the rearmost part of the aircraft, so that the driver does not get down to the field. You can descend from the rear to the shore, eliminating the need to walk in the field.

  The passage is continuous with a step that continues from the lateral side of the engine bonnet to the floor of the driver's seat at the front of the fuselage, and a passage that allows an operator to walk from the front to the rear of the fuselage.

  In this way, when the passage where the worker can walk from the foremost part to the rearmost part of the aircraft is provided continuously, when the front of the aircraft is close to the shore, or when the rear of the aircraft is close to the shore In either case, the driver can move to the shore without getting off the field. Therefore, when getting off to the shore, the direction of the aircraft relative to the shore can be made arbitrary.

  The passage is preferably provided on both sides of the body in the width direction. That is, when the preliminary seedling stand and the fertilizer hopper are mounted in parallel in the width direction, if the passages are also provided on both sides in the width direction, the operator can replenish from the closer passage side, and workability can be improved. . However, it does not necessarily have to be provided on both sides. If the planting part has four rows of plants, etc. and there is one frame in the vehicle length direction of the aircraft, the passage from the driver's seat to the rearmost part is the center in the vehicle width direction. One is provided at the position.

Specifically, a unit including a seedling platform, a planting unit, and, if necessary, a side strip fertilizer machine is mounted in parallel in the vehicle width direction at an intermediate position between the front and rear wheels, and the driver's seat is placed in front of the unit. In the mid-mount type rice transplanter equipped with a spare seedling stand on the back of the unit and an auxiliary seat at the rear,
The passage passes between the units mounted in parallel to reach the upper step for the reserve seedling platform, and the upper step is continued to the steps on both sides of the assistant seat at the rear end of the vehicle body. In the case of six-row planting in which the above units are mounted in three rows, a passage is provided between adjacent units, and a pair of left and right passages are provided.

  The passage in the portion reaching the upper step for the reserve seedling platform from the driver seat uses the upper surface of the vehicle body frame in the vehicle length direction as the passage. In that case, it is preferable to provide unevenness on the upper surface of the frame to prevent slipping. The passage on the upper surface of the frame reaches the floor of the passenger seat at the rearmost part of the fuselage, and therefore, the passage is continuous from the floor of the driver's seat → the passage on the upper surface of the fuselage frame → the passenger seat floor.

  In this way, when the vehicle body frame in the vehicle length direction is used as a passage that continues from the driver's seat floor to the steps on both sides of the passenger seat, there is no need to attach a dedicated member for the passage, space is not required, and the structure Simplification can be achieved, and further, the cost is not increased by installing the passage.

  Furthermore, it is preferable that a handrail is provided at a required portion of the passage to ensure safety during walking.

In order to enable the operator to easily perform fertilizer supply to the fertilizer hopper, which is the second problem, in an easy posture,
In the mid-mount riding rice transplanter provided with a planting part that can be raised and lowered between the front and rear wheels, and provided with a fertilizer hopper of a side strip fertilizer fixed to the planting part in front or behind the planting part,
A step for supporting the fertilizer to the fertilizer hopper and a step for supplying fertilizer for temporary storage of fertilizer bags are provided in the fuselage frame, and a step-like auxiliary that allows the worker to get on and off the fertilizer supply step from the outside of the fuselage There is provided a riding rice transplanter which is provided with a step, and the upper end of the auxiliary step is rotatably attached to the fertilizer replenishing step or the machine body so that it can be stored on the machine body side when not needed.

  The fertilizer replenishment step is set at a position immediately before or immediately after the fertilizer hopper so that when the operator stands on the fertilizer replenishment step, the position becomes higher than the position of the inlet, and the worker may stand up. In addition to being able to do so, it has the area and strength to temporarily place the fertilizer bag.

  If the above fertilizer replenishment step is provided, the operator can ride on the fertilizer replenishment step and replenish the fertilizer to the fertilizer hopper from above. It is not necessary to take an unreasonable posture to put in. In addition, the fertilizer can be continuously supplied to the fertilizer hopper from the fertilizer bag temporarily placed in the fertilizer supply step, and the fertilizer supply work can be greatly improved.

Furthermore, as described above, a step-like auxiliary step is provided in succession to the fertilizer replenishment step, and the lowest step of the auxiliary step is set at a low position of 55 cm or less from the ground. Therefore, if necessary, the operator can get on and off the field outside the aircraft through this auxiliary step.
In addition, if the auxiliary step is fixed in a state of protruding out of the aircraft, the auxiliary step may come into contact with the shore when turning the aircraft along the shore. In this case, it can be stowed upward to improve usability.

  Specifically, there is an engine bonnet at the front of the fuselage, a driver's seat at the rear of the fuselage, a planting part is provided between the driver's seat and the engine bonnet, and a fertilizer hopper is located in front of the planting part and immediately after the engine bonnet. In this case, the fertilizer supply step includes an upper step on the upper part of the engine bonnet and a lower step on either the left or right side of the engine bonnet, and one end of the auxiliary step is attached to the outer end of the lower step. It is continuous and is configured to rotate above the lower step during storage.

  It is preferable that the lower step for fertilizer assistance and the stepwise auxiliary step continuous to the lower step are provided on both the left and right sides of the machine body with the engine bonnet interposed therebetween. In other words, the airframe can be traversed by continuing the left and right auxiliary steps, the left and right lower steps, and the central upper step. With this configuration, the operator can ascend and descend from either the left or right side of the machine body, and the fertilizer can be replenished from either the left or the right with respect to the fertilizer hopper.

  It is preferable that the fertilizer replenishment step is continuous with a path through which an operator can walk to both front and rear ends or one end of the aircraft. For example, if the lower step of the fertilizer replenishment step is made to continue to the passage provided in the aircraft, the worker can be seen from the side of the passage on the side of the engine bonnet at the forefront of the aircraft or the passage at the rear of the aircraft. Can get on and move to the fertilizer replenishment step, so that it is not necessary to get off the field.

In addition, in the mid-mount type riding rice transplanter that has a planting part that can be raised and lowered between the front and rear wheels, and a fertilizer hopper of a side fertilizer fertilizer is installed on the upper part of the planting part,
At the rear of the planting portion, a fertilizer replenishing step serving as a scaffold for an operator who replenishes the fertilizer hopper is provided on the body frame.

In addition, a lower step that is continuous with the fertilizer supply step is provided at the rear end of the aircraft, and the lower step is disposed at a position that is substantially the same height as the shore when the aircraft is close to the shore.
The lower step and the fertilizer supply step are also used as a temporary storage place for the fertilizer bag.

  When the fertilizer hopper is provided in the upper part of the planting part as described above, the position of the upper surface inlet of the fertilizer hopper is higher than the case where the fertilizer hopper is arranged in front of or behind the planting part. . Therefore, a fertilizer replenishment step protrudes from the body frame behind the planting portion, and an operator can ride on this step to replenish the fertilizer and temporarily place the fertilizer bag.

  In addition, when the reserve seedling stand is arrange | positioned behind the planting part, it is preferable to use together the step for supplying a reserve seedling to this reserve seedling stand with the said step for fertilizer supply.

  As is clear from the above description, according to the present invention, the driver can go down from the rear part of the aircraft through the passage on the aircraft, so that it is not necessary to get down to the paddy field at the time of replenishment work. Can be increased. In particular, in a riding rice transplanter in which the driver rides on the front of the aircraft and the reserve seedling platform is located on the rear of the aircraft, the operator can move freely from the front to the rear of the aircraft through the passage provided in the aircraft. Has the effect of being able to perform each work very efficiently for rice transplanters with many incidental work.

  As described above, in the mid-mount riding rice transplanter according to the present invention, when supplying fertilizer to the fertilizer hopper of the side fertilizer applicator, the rear or front of the rice transplanter is stopped close to the cold, and the worker is stopped. Can temporarily place a plurality of fertilizer bags that have been placed on the fertilizer on the fertilizer replenishment step through a step provided on the fuselage. As a result, it is not necessary to go to the fertilizer bag on the shore each time after fertilizer is fed from the fertilizer bag to the fertilizer hopper, and workability can be improved.

  In addition, even if the fertilizer hopper has a large capacity and its input port is at a high position, a fertilizer replenishment step is provided. It can be carried out.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The riding rice transplanter of the first embodiment shown in FIGS. 1 to 5 is a mid-mount type in which a planting part 13 is mounted on the body 10 at an intermediate position between the front and rear wheels 11 and 12. The planting part 13 arranges three units 15A, 15B, and 15C in parallel, and each unit performs planting of two strips.

  An engine E is mounted on the front part 10F of the body 10 of the riding rice transplanter, and there is a driver's seat 16 between the planting parts 13 at the rear part of the engine E. , 18B, and an auxiliary seat 17 is provided in the center of the rear part 10B of the fuselage. Each of the units 15A to 15C includes a planting part 21 attached to the machine body so as to be movable up and down, a side strip fertilizer machine 220 provided with a fertilizer hopper 22 arranged on the top of the planting part 21, and a rear part on the planting part 21. And the seedling placing stand 20 arranged in the above. Since the fertilizer hopper 22 of the above unit is arranged at the upper part of the planting part 21, the height of the fertilizer inlet 22a located on the upper surface thereof is also higher than the machine frame arranged in the longitudinal direction of the machine. Yes.

  Steps 26 and 27 that allow an operator to walk are provided on both sides of the hood 25 of the engine E at the front of the machine body. In these steps 26, 27, the front horizontal portions 26 a, 27 a continue to the inclined portions 26 b, 27 b, and the inclined portions 26 b, 27 b are continuous on both sides of the driver seat floor 28.

  At the rear end of the driver's seat floor 28, a pair of vehicle frames 29, 30 in the vehicle length direction provided between the front and rear wheels are arranged in a continuous state. These fuselage frames 29 and 30 pass between the units 15A and 15B of the planting part 13 at the rear of the driver's seat, between 15B and 15C, and reach the upper step 31 above the rear wheel 12.

  As shown in FIG. 5, the airframe frames 29 and 30 are each composed of three vertical plates 29a and 30a spaced apart from each other, and uneven surfaces 29b and 30b are provided on the upper surfaces of the vertical plates 29a and 30a to prevent slipping. As the passages 32 and 33, the worker can walk. The rear portions of the passages 32 and 33 including these body frames 29 and 30 are inclined so as to continue to the upper step 31.

  The upper step 31 is a step for supplying fertilizer, and is a step for an operator to be loaded when fertilizer is supplied to the fertilizer hopper 22, but a step for the worker to be loaded when the spare seedling is placed on the spare seedling platforms 18A and 18B. Doubles as The upper step 31 serving as a fertilizer replenishment step serves as a scaffold for the operator to place and replenish the fertilizer and has a width and strength sufficient to temporarily place the fertilizer bag. Further, when an operator stands in the upper step 31, the position of the operator's arm is higher than the input port 22a on the upper surface of the fertilizer hopper 22, and the fertilizer can be dropped into the input port 22a from above without lifting the fertilizer bag. I am doing so.

  Lower steps 34 and 35 on both sides of the assistant seat 17 are located at the lower rear of the upper step 31 described above, and the passage from the upper step 31 to the lower steps 34 and 35 becomes the passage at the rear end of the aircraft. The heights of the lower steps 34 and 35 located at the rearmost part of the machine body are set so as to be substantially the same height as the shore when the rice transplanter is located in the paddy field.

As described above, the driver's seat floor 28 continues to the lower steps 34 and 35 on both sides of the auxiliary seat at the rear end of the vehicle body via the passages 32 and 33 including the fuselage frames 29 and 30 and the upper step 31. A passage reaching the rearmost portion will be provided.
Although not shown in the drawing, handrails are provided at necessary portions of the upper step 31 and the passages 32 and 33.

  As described above, if a passage through which an operator can walk from the driver's seat to the airframe rearmost part 10B is provided, as shown in FIG. From the driver's seat, the passage 32 or 33 is passed, the upper step 31 is passed, the step 34 or 35 next to the last assistant seat is reached, and the step 34 or 35 can get off to the shore. That is, there is no need to go down to the field and go around the aircraft to go to the shore. Work to replenish spare seedlings, fertilizers, etc. from the shore to the spare seedling platform and fertilizer hopper of the aircraft can also be done by walking along the aisle, so there is no need to go down to the field during replenishment work, increasing the efficiency of replenishment work it can.

Specifically, it is most efficient to work in the following procedure when replenishing seedlings and fertilizer at the shoreline.
(1) After turning the aircraft at the shore, move backward, and bring the rear of the aircraft closer to the shore and stop the machine.
(2) The driver gets down to the shore from the rear of the aircraft through the passage.
(3) Load seedlings that are pre-arranged on the shore into spare seedlings at the rear of the aircraft.
(4) Replenish fertilizers pre-arranged on the shore from the rear of the aircraft.
(5) The driver returns to the driver's seat through the passage again and resumes the rice transplanting work.

  At the time of replenishment of the above-mentioned spare seedlings and fertilizer, it is placed on the upper step 31 from the lower step 34 or 35, and an operator stands on the upper step 31 to place the spare seedlings on the spare seedling platforms 18A and 18B, and the fertilizer hopper 22 Fertilizer is replenished from the inlet. At this time, since the hopper inlet is located below the position of the operator's arm, the operator can replenish the fertilizer hopper 22 with fertilizer from a heavy fertilizer bag in an easy posture.

When the front part of the machine is close to the shore, the spare seedlings must be transported one by one to the spare seeder at the rear of the machine, and the fertilizer bag must be transported to the hopper. Is very low. Therefore, work efficiency can be improved if it can go to the shore from the rear part of an airframe and can perform the said operation | work.
However, even when the front part of the fuselage is brought close to the shore, the steps 26 and 27 on both sides of the engine bonnet can be moved to the shore, and the spare seedling and the fertilizer can be replenished without getting off the field. .

  In addition to the above seedling and fertilizer replenishment operations, rice planting may go to the rear of the aircraft to check the planting area. Furthermore, in some operations such as refueling the engine, it may be easier to work closer to the shore of the front of the fuselage. In this case, since the driver's seat floor is continuous with the steps 26 and 27 on both sides of the engine bonnet, it is possible to get off to the shore through the step 26 or 27 without getting down to the farm field from the front of the machine body. .

Note that the present invention is not limited to the above embodiment, and in the case of a four-plant rice transplanter and the number of the body frame is one in the vehicle width direction, the passage using the body frame is from the driver's seat to the highest part of the body. The passage that reaches is one in the center in the width direction.
Further, when the body frame is used as the passage, it is not necessary to waste space and attach another member, but it is not always necessary to use the body frame, and an appropriate member may be provided as the passage.

  6 to 9 show a second embodiment. The second embodiment is a mid-mount riding rice transplanter that is a single-seat type and does not have an auxiliary seat. In addition, the same code | symbol is attached | subjected to the member similar to the said 1st Embodiment.

  In the rice transplanter, a fertilizer machine 220 including a fertilizer hopper 22 is arranged in the vicinity of the rear part of the engine bonnet 25 at the front of the machine body, and a planting part 21 that can be raised and lowered is arranged at the rear part of the fertilizer machine 22. A seedling stand 20 is arranged on the rear upper part of the planting part. In this embodiment, three units including the fertilizer applicator 220, the planting unit 21, and the seedling placing table 20 are provided, and are arranged in parallel at the rear part of the engine bonnet 25. A driver's seat 16 is provided at the center of the rear portion of the seedling table 20, and spare seedling tables 18A and 18B are provided on the left and right sides thereof.

  On the upper surface of the rear part of the engine bonnet 25 at the front of the machine body, an upper step 50 for replenishing fertilizer is disposed so as to cover the left and right sides of the engine bonnet, and lower steps 51 and 52 are provided. It is possible to get on and off the upper step 50 from either 51 or 52.

  As shown in FIGS. 8 (A) and 8 (B), the upper step 50 on the engine bonnet 25 is provided with an inverted U-shaped support frame 55 erected from the fuselage frames 53 and 54 immediately behind the engine bonnet 25. The upper step 50 is rotatably attached to the horizontal horizontal shaft portion 55a of the frame 55. The upper step 50 has a rectangular shape in which a plurality of inner frames 50b having irregularities on the upper edge are attached to the inside of a metal outer peripheral frame 50a. Both sides of the outer peripheral frame 50a of the upper step 50 are rotatably attached to a bracket 55b projecting from the horizontal horizontal shaft portion 55a through a shaft 51.

  The upper step 50 is rotatably attached to the support frame 55 as described above, so that when fertilizer is replenished, it is positioned horizontally above the engine bonnet 25 to serve as a scaffold for the operator, as shown in FIG. 8B. As described above, when it is necessary to open the fuel supply port 25b provided in the engine bonnet 25 to supply the fuel, the upper step 50 is raised upward so that the fuel supply port 25b can be opened.

As shown in FIG. 8 (A), the left and right lower steps 51 and 52 include inner portions 51a and 52a formed on the lower steps of the left and right sides of the engine bonnet 25, and a horizontal plate 56 protruding outward from the body frame. 57, outer portions 51b and 52b fixed in a horizontal direction via support frames 58 and 59.
The inner portions 51a and 52a are laid with rubber mats on the upper surface, while the outer portions 51b and 52b are made of a metal frame similar to the upper step 50.

  The upper ends of the step-like auxiliary steps 60 and 61 are rotatably attached to the outer ends of the outer portions 51b and 52b of the lower step by shafts 62 and 63, respectively. These auxiliary steps 60 and 61 have a shape in which horizontal axes 60b and 61b are provided inside rectangular outer peripheral frames 60a and 61a. In the auxiliary steps 60 and 61, when the driver goes down to the field, it is lowered downward as shown by the solid line in FIG. 9, and at that time, the lowermost steps 60c and 61c are lower than the lower end surface of the wheel to be grounded by 55 cm or less. To be in position. Therefore, if necessary, the operator can get on and off the field outside the aircraft through this auxiliary step. When not required, as shown by a dashed line in FIG. 9, the upper end is rotated as a fulcrum and stored.

  The fertilizer replenishment step and the auxiliary step have sufficient strength and area even if the operator holds the fertilizer bag. When an operator stands on the upper step 50 on the engine bonnet of the fertilizer assisting step, the operator's arm is positioned above the upper surface inlet of the fertilizer hopper 22, and the operator does not lift the fertilizer bag. The fertilizer can be put into the hopper.

The lower steps 51 and 52 on the left and right sides of the engine bonnet 25 are connected to the left and right gently inclined steps 65 and 66 that continue to the front end of the engine bonnet 25.
In the passenger rice transplanter of this embodiment, since the fertilizer hopper 22 is arranged directly behind the engine bonnet 25, unlike the first embodiment, the front part of the machine body is brought close to the shore, and the side of the engine bonnet is We go down to the shore through the steps and replenish the fertilizer on the shore.

  The driver's seat 16 at the rear of the machine body is provided at the center of the upper step 31 protruding from the machine frame, and spare seedling platforms 18A and 18B are attached to both sides thereof. The upper step 31 serves as a scaffold for the operator when the preliminary seedlings are placed on the preliminary seedling platforms 18A and 18B. In addition, as in the first embodiment, a lower step 34 that is continuous to the upper step 31 is provided, and the lower step 34 has substantially the same height as the shore. Therefore, when the spare seedling is replenished, the rear part of the machine body is brought close to the shore, passes through the lower step 34 from the upper step 31, and descends to the shore to replenish the spare seedling.

In the riding rice transplanter of the second embodiment, by providing the fertilizer replenishment step and the auxiliary step, fertilizer replenishment and spare seedling replenishment can be performed easily and efficiently by the following procedure.
(1) First, bring the front of the aircraft closer to the shore and stop the machine.
(2) An assistant at the shore holds the fertilizer bag from the shore, passes the passage 65 or 66 on the side of the engine bonnet 25, and temporarily places the fertilizer bag on the fertilizer supply steps 51 and 52. At this time, even if there are a plurality of fertilizer bags, they can be easily put on without entering the field.
(3) Turn the aircraft around the shore, bring the rear of the aircraft closer to the shore and stop the machine.
(4) The driver descends to the shore from the lower step 34 at the rear of the aircraft, and performs operations such as loading of a seedling.
(5) Once entering the farm from the shore, go to the position of the fertilizer hopper 22 on the front side of the aircraft through the side where the rice planting has not yet been done, and climb the step-like auxiliary step 60 or 61 on the side of the aircraft, Take the fertilizer replenishment step 51 or 52.
(6) The fertilizer is temporarily supplied onto the fertilizer supply steps 51 and 52, and the fertilizer is supplied from the lower step 51 or 52 on the engine bonnet 25 to the fertilizer hopper 22 on the left and right sides. At this time, since the upper step 50 on which the operator is riding is also at a high position, the fertilizer can be replenished in an easy posture even if the position of the inlet 22a of the fertilizer hopper 22 is high.
(7) Through the fertilizer replenishment step 50 on the engine bonnet 25, it moves across to the opposite side of the machine body without getting down to the field, and the other fertilizer hoppers 22 are sequentially replenished with fertilizer. At this time, since a plurality of fertilizer bags are temporarily placed on the steps 51 and 52, it is not necessary to return to the side to collect the fertilizer bags each time. Once the steps rise to the steps 51 and 52, to all the fertilizer hoppers 22. Can be replenished with fertilizer.
(8) When all the fertilizer hoppers 22 have been replenished with fertilizer, go through the auxiliary step 60 or 61 on the rising side, get down to the unplanted field, return to the shore, and then return to the driver's seat Resume rice transplanting.

  Since the fertilizer replenishment work can be performed in the above steps, the fertilizer bag can be directly carried from the shore into the machine body and placed on the machine body without entering the field. In addition, even if the fertilizer hopper is a large capacity hopper, it can be replenished on the fertilizer replenishment step, so it can work in an easy posture as if dropping the fertilizer into the fertilizer hopper from above . In addition, it is not necessary to make a detour around the aircraft in the field, especially through the field on the side where planting has been completed. Can move to. Moreover, since the fertilizer bag can be temporarily placed in the step, it is not necessary to go back and forth with the fertilizer bag to the shore.

In the passenger rice transplanter of the second embodiment, as in the first embodiment, a passage continuing from the rearmost driver's seat 16 to the lower steps 51 and 52 on the side of the engine bonnet 25 is used on the upper surface of the body frame. May be formed. In this case, the driver can reach the lower step 51 or 52 through the passage, and can go down to the shore through the inclination steps 65 and 66.
Therefore, even when replenishing fertilizer, the work can be performed without getting off the field.
