Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a riding type rice transplanter that is equipped with a seedling planting device at the rear of the passenger car body and a spare seedling stand on the side of the front part of the car body. .

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Application Publication No. 56-108428, the spare seedling stand placed on the side of the front of the vehicle body was placed on the side of the vehicle body so as not to obstruct the forward view from the driver's seat. It was placed at an appropriate distance from the side.

[The problem that the idea aims to solve]

However, with the conventional riding rice transplanter mentioned above,
Because the spare seedling stand was fixed to the machine body, it was difficult to take out the spare seedlings from the control section, and when the machine turned at the edge of the field, the spare seedling stand collided with the ridge. I have an easy problem to solve.

In this invention, the spare seedling stand placed at the front of the vehicle body does not obstruct the forward view, and the spare seedlings can be easily taken out from the control section.
Moreover, it is an object of the present invention to make it possible to avoid collision of the spare seedling stand with the ridge when turning at the edge of the ridge.

[Means to solve the problem]

The characteristic structure of this invention to achieve the above purpose is as follows:
The stand for placing spare seedlings is positioned inside the machine within the width of the seedling planting device while remaining in a position where the spare seedlings can be placed, and the machine is positioned outside the width of the seedling planting device. The main feature is that the position can be changed and fixed freely across the outer position and in the width direction of the fuselage.

[Effect]

The following effects can be obtained from the above configuration.

a.In other words, during work, by positioning the stand for placing spare seedlings on the outer side of the vehicle body than the seedling planting device, a space is created between the side of the machine and the stand for holding spare seedlings, allowing for a clear view of the front. be done.

b When taking out spare seedlings or turning the machine at the edge of a ridge, the spare seedling stand is placed as far inside the machine as possible within the width of the seedling planting device. It can be placed on the side.

c In addition, since the movement of the spare seedling stand is in the width direction of the machine, for example, the spare seedling stand can be rotated toward the rear of the machine around the vertical axis using the rear end as a fulcrum. This helps avoid collisions with the ridges, and makes it easier to take out spare seedlings from the control section.As a result, the front and rear balance of the aircraft does not collapse when the spare seedling stand is moved, and the front wheels do not lift up. It can be avoided.

[Effect of idea]

(b) Due to the effect of ab above, the protrusion of the spare seedling stand to the outside of the aircraft during work should be made sufficiently large to improve forward visibility, but when taking out spare seedlings or turning the aircraft at the edge of a ridge. By locating the spare seedling stand as far inside the machine as possible,
There are advantages in that it is easy to take out the spare seedlings from the control section, and it is easy to avoid contacting the stand with the spare seedlings against the ridges.

(b) Due to the effect of c. above, there is no change in the front-to-back balance of the machine regardless of the position of the spare seedling stand, and
Controlling the lifting of the front wheels makes it easier to maneuver.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 and 2, it is equipped with a pair of left and right front wheels 1, 1 that can be driven and rotated and whose direction can be changed, and a pair of left and right rear wheels 2, 2 that can be driven and rotated,
Engine 3 and transmission case 4, driver's seat 5
an inclined seedling platform 6 that moves back and forth horizontally at a constant stroke with four pine-shaped seedlings W placed side by side in the rear of the passenger vehicle body, which is located in front of the vehicle and at the front end of the vehicle; Seedlings equipped with four planting claws 7 that take out and plant one seedling from the lower end of each pine-shaped seedling W, and three floats 8 arranged side by side at appropriate intervals in the lateral direction. The planting device 9 is connected so as to be able to rise and fall via a pair of upper and lower lifting links 10a, 10b, and a hydraulic cylinder 11 for lifting and lowering the seedling planting device is connected to the lifting links 10a, 1.
0b is installed in such a way that it can be operated up and down with respect to the vehicle body, and four rows of seedlings are planted sequentially as the vehicle advances. In order to avoid contact of the seedling planting device 9 with the ground when traveling on the ground or on the road, the seedling planting device 9 is configured to be able to be raised and lowered relative to the vehicle body.

As shown in FIG. 3, a plurality of spare seedling stands 13 for mounting and supporting the spare seedlings WA placed on the seedling holding plate 12 are installed on each side of the bonnet 14 of the engine 3. A horizontal frame 15 is installed at the lower end of a pair of front and rear vertical frames 15A and 15B that are arranged vertically and connect and support the front and rear ends of each preliminary seedling stand 13.
a, 15b are connected, and both horizontal frames 15a, 15b are supported by a roller 17 that is fitted inside the cylindrical fixed guide 16 so as to be able to slide horizontally, and the horizontal frames 15a, 15b are connected to each other.
A spring 18 is provided to bias the control lever 21 toward the outside of the vehicle body, and by swinging the operating lever 21 upward, the horizontal frames 15a and 15b are slid toward the outside of the vehicle body, and by swinging downward. Horizontal frame 15a, 15b
so that it can be moved towards the inside of the vehicle.
Both horizontal frames 15a, 15b are interlocked and connected via wires 22, and a lever 21 is connected to the driver's seat 5.
A spare seedling stand 13 is provided near the stand so that it can be locked and fixed at both the upper position and the lower position.
The seedling tray 6 is configured to be able to change its position between an inside position within the machine, which is located within the width of the sliding rail 6a, and a position outside the machine, which is located outside the width of the sliding rail 6a. There is.

As shown in Figs. 1 and 2, an adjacent marker 19 is provided with a lamp 20 at its tip, which is used as a guide when moving the machine along the planted seedlings WB located on the side of the machine. It is constructed so that the planted seedlings WB can be accurately confirmed even when working at night, and is also constructed so that it can be used as a vehicle side light when driving on the road at night.

In carrying out the present invention, a drive device such as a hydraulic cylinder may be used to move the preliminary seedling stand 13 laterally.

Moreover, when changing the position of the preliminary seedling stand 13, its support structure can be changed in various ways. Then, the support may be supported so that the position inside the body is closer to the rear than the position outside the body, for example, from the position outside the body to the rear lateral inward direction.
