BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking rice transplanter equipped with a fertilization device.

0002

[Prior art] As a conventional technology of this kind, there is a
There is a rice transplanter equipped with a fertilizing device as shown in Japanese Patent No. -138512.

0003

[Problems to be Solved by the Invention] In the conventional rice transplanter equipped with a fertilizer application device, the top surface of the fertilizer tank of the fertilizer application device is located at a position considerably higher than the top surface of the machine body in front of the fertilizer tank, so the center of gravity of the machine is high. In addition, the center of gravity of the machine fluctuates greatly depending on the amount of fertilizer in the fertilizer tank, causing problems in running stability and making it impossible to perform rice transplanting and fertilization properly.

0004

[Means for Solving the Problems] In order to solve the above problems, the present invention provides fertilizer tanks 19 and 20 between the left and right wheels 6 and 7 provided on both the left and right sides of the machine body 1.
A fertilizer application device A is provided, which is composed of feeding devices 19a and 20a that feed fertilizer from zero and guide bodies 19b and 20b that guide and transfer the fed fertilizer to the field.・20d for fertilizer tank 1
A rice transplanter with a fertilization device is characterized in that it is located at approximately the same height as the upper surface 1a of the machine body forward of the fertilizer tank 19 and 20, and that preliminary seedlings are placed above the fertilizer tank 19 and 20. It is something.

[0005]

According to the present invention, the upper surfaces 19d and 20d of the fertilizer tanks 19 and 20 of the fertilizer application device A provided between the left and right wheels 6 and 7 provided on both the left and right sides of the machine body 1 are removed from the fertilizer tanks 19 and 20. Since it is located at approximately the same height as the front upper surface 1a of the aircraft, it is possible to lower the center of gravity of the machine, and even if the center of gravity of the machine changes depending on the amount of fertilizer in the fertilizer tank, it will not affect running stability. Therefore, good rice planting work and fertilization work can be performed. Furthermore, since the spare seedlings are placed above the fertilizer tanks 19 and 20, whose top surfaces 19d and 20d are located at approximately the same height as the front top surface 1a of the aircraft, the spare seedlings can be placed Since the height of the machine is not too high and does not obstruct the forward view, combined with the low center of gravity of the machine, it is easy to operate the machine in a straight line, and the rice planting work can be carried out properly and efficiently.

The structure is such that seedlings are planted at a rear seedling planting position in between and a rear seedling planting position outside the left and right wheels 6 and 7.

A central leveling float 14 and a pair of left and right side leveling floats 15 are attached to the lower abdomen of the fuselage 1.
It is configured to support part of the weight of the aircraft 1 and slide on a mud surface. A spare seedling stand 21 configured in upper and lower stages is fixed to the machine body 1 so as to be above the left and right wheels 6 and 7 when viewed from the side.

The fertilization device 16 includes a fertilization device A provided within the width of the left and right wheels 6 and 7 when viewed from the front of the machine, and
It is composed of left and right fertilizer application devices B and C provided on the outside of the fertilizer application device 7. Then, each fertilizer application device A, left and right fertilizer application device B,
C stands for fertilizer tank 19, 20, 17, 1.
8, and a feeding device 19a that feeds out fertilizer, which is integrally attached to the lower part of these fertilizer tanks 19, 20, 17, and 18.
・20a, 17a, 18a, and guide bodies 19b, 20b, 17b, 18 consisting of pipes that guide and transfer the delivered fertilizer
These fertilizer tanks 17, 18, 19,
20 is provided within the length L of the left and right wheels 6 and 7 when viewed from the side. And the fertilizer tanks 19 and 20 in the center are
It is provided below the preliminary seedling platform 21 so that its upper surfaces 19d and 20d are approximately at the same height as the upper surface 1a of the front body. Moreover, the feeding devices 19a, 20a and the guide bodies 19b, 20b of the fertilizer application device A are provided within the width of the left and right wheels 6, 7 when viewed from the front of the machine, and the feeding devices 17a, 18a of the left and right fertilizer application devices B, C are provided.

The left and right fertilizing devices B and C apply fertilizer corresponding to the rear seedling planting position on the outside of the left and right wheels 6 and 7. In addition, the fertilizer supply pipes 19c and 20 to the fertilizer tanks 19 and 20 in the center of these
C is provided on the inner side of the outer fertilizer tanks 17 and 18, and is configured so that the fertilizer supplied to the outer fertilizer tanks 17 and 18 is replenished from the supply ports I and B.

When the rice transplanter constructed as described above is operated in a field, the left and right wheels 6 and 7 are driven and rotated by the power of the prime mover 5, and the central soil leveling float 14 and the side leveling floats 15 are rotated.
・Aircraft 1 moves forward while Aircraft 15 slides on the mud surface. Then, the seedling platform 12 is moved left and right by the power of the prime mover 5, and the tip of the seedling planting device 13 passes through the lower end of the seedling platform 12 from above to the bottom by the power of the prime mover 5, and is placed on the mud surface. Since the seedlings on the seedling stand 12 reach the seedling planting device 13...
The rice is divided at the tip, and seedlings are planted on the muddy surface for rice transplantation.

[0012] At the same time as this rice planting work, the fertilizer in each of the fertilizer tanks 17, 18, 19, and 20 is quantitatively dispensed by the respective fertilizer dispensing devices 17a, 18a, 19a, and 20a, and then the guide body 17b・18b・19
Fertilizer is applied to the mud surface at step b/20b, and fertilization work is carried out. When the number of seedlings on the seedling platform 12 becomes low during the operation in this way, the operator stops the operation of this rice transplanter and moves the seedlings on the preliminary seedling platform 21 onto the seedling platform 12. Resuming rice planting work.

In particular, fertilizer tanks 19 and 20 are provided between the left and right wheels 6 and 7 provided on both the left and right sides of the machine body 1, and feeding devices 19a and 20a that feed the fertilizer from the fertilizer tanks 19 and 20 are used to transfer the fed fertilizer to the field. Guide body 19b/2 to be guided and transferred to
0b is provided, and the top surfaces 19d and 20d of the fertilizer tanks 19 and 20 of the fertilizer application device A are located at approximately the same height as the top surface 1a of the aircraft body forward of the fertilizer tanks 19 and 20. Because of this, the center of gravity of the machine can be lowered, and even if the center of gravity of the machine changes depending on the amount of fertilizer in the fertilizer tank, it does not affect running stability much, and therefore, it is possible to perform rice planting and fertilization operations in a good manner. can. Furthermore, since the spare seedlings are placed above the fertilizer tanks 19 and 20, whose top surfaces 19d and 20d are located at approximately the same height as the front top surface 1a of the aircraft, the spare seedlings can be placed Because the height is not too high and does not obstruct the forward view,
Combined with the low center of gravity of the machine, it is easy to operate the machine in a straight line, allowing for appropriate and efficient rice planting work.
