Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a riding-type rice transplanter.

[Prior art]

Previously, Utility Model Application No. 52-59613 and Utility Model Application No. 54-
There was a rice transplanter for odd number row planting as shown in Publication No. 25422.

[Problem to be solved by the invention]

In the conventional odd-row rice transplanter mentioned above,
The left side of the machine has a transmission case with a seedling planting device on only one side, and the right side has a transmission case with seedling planting devices on both sides. The weight balance was very poor and it was not practical.

[Means to solve the problem]

This invention has taken the following technical measures for the purpose of solving the problems of the conventional rice transplanter described above.

That is, the planting portion transmission case 7 is provided with left and right transmission cases 9, 11 extending rearward and a middle transmission case 10, and the left and right transmission cases 9, 11 are provided with seedling planting devices 14, 15, on both left and right sides, respectively. 16 and 17, and a seedling planting device 18 is provided only on one side of the middle transmission case 10 to form a configuration for five-row planting.

[Function and effect of the invention]

In this invention, seedling planting devices 14, 15, 1 are provided on the left and right sides of each of the left and right transmission cases 9, 11.
6 and 17, and the seedling planting device 18 is provided only on one side of the middle transmission case 10, making it a riding type rice transplanter for planting 5 rows, so the weight balance in the left and right direction is very good. 5. Good planting performance that can solve the problems of rice transplanters that plant in odd rows.
A riding type rice transplanter for row planting can be obtained.

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a passenger vehicle body, and left and right front wheels 2, 2 for steering are provided at the lower front side, and left and right rear wheels 3, 3 are provided at the lower rear side to be driven and rotated. , there is a control handle 4 on the top of the aircraft.
It also has a pilot seat 5.

Reference numeral 6 denotes a rice-transplanting work machine for 5-row planting, and a planting part transmission case 7 that also serves as the frame projects from a main transmission case 8 at the front and from this main transmission case 8 at a predetermined left and right interval. left and right transmission case 9,
11, and a middle transmission case 10. 1
Reference numeral 2 denotes a seedling tank, which is supported above the main transmission case 8 with the front side facing upward, and is provided so as to be reciprocated from side to side by a reciprocating mechanism 13.

Reference numerals 14, 15, 16, 17, and 18 are seedling planting devices, respectively, and the seedling planting devices 14, 15, 16, and 17 are provided on both sides of each of the left and right transmission cases 9 and 11, and Seedling planting device 1 on one side
8 are provided and their seedling planting devices 14,1
Each of the planting claws fixed to the front ends of the seedlings 5, 16, 17, and 18 is configured to operate while drawing a loop-shaped seedling planting locus vertically and downwardly.

The seedling planting device 18 is provided so that its planting claws are located on the left-right center line A of the rice-transplanting machine 6.

19 is a link for lifting and lowering, the base of which is connected to the passenger vehicle body 1;
The rolling support shaft 20 is pivotally attached to the rear of the
A rice transplanting work machine 6 is mounted so as to be able to roll freely.

The planting claw portion of the seedling planting device 18 is located on the axial extension line of the rolling support shaft 20, and the planting position thereof is located on the rolling center line A.

In addition, 21 is a center leveling float, and 22 and 23 are side leveling floats, which are installed below the planting unit transmission case so that the front part can move up and down with the rear part as a fulcrum. It is provided to level the soil surface in front of the planting position of the planting device.

In the configuration of the above example, after seedlings are placed and accommodated in the seedling tank 12, the riding rice transplanter is moved forward while driving each part.

Then, the rice transplanting machine 6 is pulled by the soil leveling floats 21, 22, 23 floating on the topsoil surface of the field.
The seedling tank 12 moves back and forth horizontally to the left and right to place and store the seedlings in each seedling planting device 14, 15, 16, 17, 18.
supply to The seedlings supplied in this way are separated and held one by one by each seedling planting device 14, 15, 16, 17, 18, and transported downward to the land leveling float 2.
Planted on the leveled soil surface in steps 1, 22, and 23. In this way, the seedling planting work is carried out, but during the work, the operator needs to be careful about straight-line operation so that the management and reaping work after planting the seedlings can be done easily and accurately. In fields with sandy soil, it is difficult to operate in a straight line, so the operator sets an appropriate target on the ridge in front of him and steers towards it. You have to look back and check whether you are doing it correctly, and you often lose sight of your target. At this time, the pilot looks at the rows of seedlings that have been planted up to that point and reestablishes an accurate target for maneuvering, but in this case,
It is required that the seedling rows to be planted later are reliably planted without meandering.

However, the row of seedlings planted by the seedling planting device 18 immediately after the pilot's seat 5 is on the rolling center line A, and the center of gravity shifts due to the left and right movement of the seedling tank 12, and the undulations of the soil surface cause the rice planting work to be difficult. Even when the machine 6 rolls, only the rows of seedlings in the center of the left and right sides meander and are not planted properly, so the operator sets the target based on the row of seedlings located in the center of the left and right sides. This enables accurate straight-line operation of the riding rice transplanter.

In particular, seedling planting devices 14, 15, 1 are provided on the left and right sides of the left and right transmission cases 9 and 11, respectively.
6 and 17, and the medium transmission case 10 is provided with a seedling planting device 18 only on one side, making it a five-row rice transplanting work machine 6, so that the weight balance in the left and right direction is very good for planting. The adhesion performance is extremely good.
