Description

The present invention relates to a ride Yoda planting machine, particularly, in an intermediate position of the front and rear wheels, seedling stand, equipped with a unit consisting of the planting unit and the side strip fertilization equipped with a fertilizer hopper, towards after said 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 the middle of rice planting work, the work to bring the front part 1F closer to the shore G is limited. In the case of mid-mount type rice transplanters, when reserve seedling and fertilizer are replenished, it is better to bring the rear part 1B closer to the shore. work facilitate, usually, as shown in FIG. 11 (C), a state of close the aft body 1B on the shores G.

  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 problems described above, can be moved up banks without getting off the 圃 field, preliminary seedlings are placed in banks, fertilizer, pre seedling stage and fertilizing machines that are installed in aircraft The first task is to be able to supply fertilizer hoppers.
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.

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 upper part 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 load when fertilizer is supplied to the fertilizer hopper 22. 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. .

The present invention is not limited to the reference implementation form, in Article 4 planted rice transplanter, when the body frame is one in the vehicle width direction, passage utilizing該機body frame, from the driver's seat in the aircraft up portion The reaching passage is one in the center in the width direction.

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.
