Description

[Detailed description of the invention] This invention relates to a riding rice transplanter in which a worker rides on the moving machine and performs rice transplanting work.In detail, the machine is bent horizontally in the middle and steered. To the traveling aircraft,
In configuring a riding-type rice transplanter by attaching a seedling-transplanting device so that it can be raised and lowered, operating parts such as a handle and a control seat, etc., which are necessary by pressing a button on the riding-type rice-transplanting machine, and operating parts, such as an engine, are attached to the seedling-type rice transplanter. This allows each device to be compacted separately without unbalancing the wheel load during rice transplanting work in which the planting device is lowered so as to touch the ground on the field.

Next, the present invention will be explained with reference to a drawing showing an embodiment of a four-row riding type rice transplanter.
and a rear fuselage 2 are connected in a horizontally bendable manner by a vertical shaft 3, and lugs, which are paddy wheels, are attached to both left and right sides of the fuselage bodies 1 and 2 via swing cases 8 and 10. Wheels If, 11°9.9 are attached, and the front wheels 11, 11.
The spacing between each rut for the rear wheel 9°9 is 1 for the seedling row spacing, while the spacing for the front wheel 11
The ratio between the rear wheels 9 and 9 is 4, and the ratio is 2 between the rear wheels 9 and 9.

The front body 1 is equipped with operation parts such as a steering wheel 4, a transmission case 5, a pilot seat 6, a clutch, an accelerator pedal, etc., and also has a power transmission mechanism (mission) to the front wheels 11, 11 and a seedling planting device 12 to be described later. On the other hand, the rear fuselage 2 is equipped with an engine 7 at its rear end and is equipped with a power transmission mechanism (mission). At the same time, the front wheels 11 and 11 are driven through the transmission in the front fuselage 1 via the outer periphery of the vertical shaft 3, and the fuselage 1' is driven by four-wheel drive.
To move the front and rear bodies 1.2 forward or backward, the operating force of the handle 4 provided upright on the front body 1 is used to control the bending direction and bending of the front and rear bodies 1.2 about the vertical axis 3 via the transmission case 5. Steering operations are performed by manipulating dust.

Reference numeral 12 denotes a four-row seedling planting device mounted on the front of the front body 1, and the seedling planting device 12 has a seedling platform 14 that reciprocates left and right on a guide rail 13. Seedling planting nail is, 1s, is, which takes out seedlings from table 14 and plants them in the field.
power is transmitted from the mission of the front body 1 through a flexible shaft (not shown) inserted into the spring mechanism 19, etc., and drives the seedling platform 14 and the seedling planting claws 15, 15, 15, 15. It consists of a planting part transmission frame 16 that stabilizes the planting, and a sliding body 17.17 that stabilizes the planting. It is connected by vertical parallel links 18.18 and a spring mechanism 19 so as to be vertically movable.

In this configuration, if the rear fuselage 2 is kept straight as shown by the dotted line in Figure 3 with respect to the front fuselage 1 where a worker sits on the front fuselage 10 seat 6, the fuselage 1' will move straight in the direction of the arrow. In this straight-ahead state, the seedling planting device 12 is lowered at 1, where each sliding body 17, 17 touches the field surface, and the seedlings are planted in multiple rows by moving the body 1' forward while sliding on the field surface. (4 rows in this example). To change direction at the edge of a ridge, etc., by rotating the handle 4 to the right or left, the front and rear of the same aircraft 1.2 will be planted in the 3rd row. As shown by the solid line in the figure, since the handle can be bent in accordance with the amount of 40 rotations, the aircraft body 1' can be turned arbitrarily to the right or left and can be steered.

In this case, according to the present invention, the engine 7 is installed in the rear fuselage 2.
Equipped with operating parts such as and power transmission mechanism (mission),
On the other hand, since the front fuselage 1 is equipped with the operating parts such as the steering wheel 4 and the pilot seat 6, the operating parts such as the engine 7 and the power transmission mechanism are mounted on the rear fuselage 2...the steering wheel 4, the pilot seat 6, etc. The operation sections can be separately provided in the front body 1 without interfering with each other, and the operation section in the rear body 2 and the operation section in the front body 1 can be compactly combined.

In the case of a riding-type rice transplanter, it is necessary to properly stabilize the planting posture of the seedlings when the seedling planting device 12 is lowered at 1 in contact with the field disease, and to stabilize the running of the traveling machine. In order to maintain the front wheels 11, 11 and rear wheels 9, which support the traveling aircraft,
It is necessary to make the amount of subsidence of the front wheels 11, 11 and the rear wheels 9 approximately equal to each other.
, 9 must be made approximately equal for each wheel, but according to the present invention, this problem can be easily solved while simultaneously making the vehicle more compact.

That is, when the above configuration is clicked and the seedling planting device 12 is raised away from the field, the weight of the seedling planting device 120 acts on the front body 1, but when the seedling planting device 12 is lowered until it touches the field. When entering the rice transplanting state, most of the weight of the seedling transplanting device 12 is removed from the front body 1 and transferred to the field side. Front fuselage 1 with two front wheels
and a rear fuselage 2 with two rear wheels, operating parts such as a handle and a control seat are mounted on the front fuselage side, and operating parts such as an engine and a power transmission mechanism are mounted on the rear fuselage side. By configuring
The front two wheels f1, li and the rear two wheels can be separated by placing the operating part on the front side and the actuating part on the rear side by sandwiching the body bending point.
The wheel loads on the wheels 9, 9 do not become significantly unbalanced as would be the case when the operating section and the actuating section are provided on either side of the aircraft, and the wheel loads on the front two wheels 11, 11 and the rear two It is possible to easily bring the wheel loads of the wheels 9, 9 closer to each other so that they are approximately equal.

As described above, the present invention provides a riding-type rice transplanter in which a front body and a rear body, each equipped with a pair of left and right wheels, are bendably connected by a vertical axis, and a seedling planting device is vertically movable. The front fuselage is provided with operating parts such as a handle and a pilot seat, while the rear fuselage is equipped with operating parts such as an engine and a power transmission mechanism, and a pair of left and right front wheels that are attached to the front fuselage; With the wheel loads on the pair of left and right rear wheels in the rear fuselage kept approximately equal without making them unbalanced, the operation parts such as the steering wheel and control seat, and the operating parts such as the engine and power transmission mechanism, They can each be constructed separately and compactly without interfering with each other, and have the effect of improving the ease of assembly and maintenance and inspection of the operating section and the operating section.
