Description

[Detailed Description of the Invention] The present invention relates to a riding rice transplanter in which a seedling planting device is connected to the rear part of the machine body, and spare seedling stands are provided on both left and right sides of the front part of the machine body.

Conventionally, the above-mentioned spare seedling stand was generally placed close to the boarding and operating section so that seedlings could be easily replenished to the seedling planting device. The distance from the stand for placing spare seedlings is large, and it is therefore necessary to enter the field to carry out the process, which is cumbersome and time-consuming.

This invention was made in view of the above circumstances.
To easily replenish seedlings to a seedling planting device with simple modification, and to easily and quickly replenish preliminary seedlings from a ridge or the like without entering the field.

Next, embodiments of the present invention will be described based on illustrative drawings.

As shown in FIG. 1, a seedling planting device 4 is connected to the rear of a traveling body 2 equipped with a pair of left and right lug wheels 1 at the front and rear through a parallel quadruple link mechanism 3 so as to be able to move up and down. A riding rice transplanter is constructed by providing standby seedling stands 5 on both the left and right sides of the rice transplanter.

To construct the rear wheel 1, as shown in FIGS. 2 to 5, a ring-shaped rim 6 is coated with an elastic material 7 such as rubber by baking or other means, and the rim 6 is coated with an elastic material 7 at appropriate intervals. A relatively wide large propulsion lug 8 made of hard rubber or the like is separated from the rim, and small lugs 9 having approximately the same width as the rim diameter and elastically coated are provided on both sides of the large lug 8, thereby generating propulsive force. While improving
The vibrations from the hard disk are absorbed by the flexure of the elastic material,
It is designed to run stably.

The seedling planting device 4 supports a planting mechanism 11, which is interlocked and connected to the planting mechanism 10 of the traveling vehicle body 2, in a constant posture with respect to the mud surface using a plurality of floats 12, and
1. A slanted seedling stand 13 is provided on the upper part of the table so as to be able to reciprocate laterally with a constant stroke, and the pine seedlings A placed on this seedling stand 13 are raised by crank-type seedling planting claws 14 arranged in parallel at the rear of the lower end. The structure is such that the plants are cut out one by one and planted on the mud surface leveled by the float 12. Moreover, the seedling planting device 4 is
In order to perform row planting such as ridge planting, a planting clutch 15 is provided for each of the two rows, and the operation linkage structure for these clutches is constructed as follows.

That is, as shown in FIG.
A guide plate 18 is mounted on which the operating lever 17 can be pivoted and operated freely, and the operating lever 17
and a shifter (not shown) of each clutch 15 are interlocked and connected by a release wire 19, and the wires 19 are bundled at multiple points in the middle with a stopper 20, thereby controlling the operation system for the planting clutch 15. By providing the seedling planting device 4 on the side of the seedling planting device 4, the seedling planting device 4 can be easily attached and detached from the traveling machine body 2.

As shown in FIG. 7, the preliminary seedling stand 5 is composed of a long side portion 21a located on the inside of the body.
A cylindrical shaft 22 is integrally connected to the front end of the long side portion 21a of the seedling placement plate 21, in which the front and rear short side portions 21b are bent upward, and a fitting portion 23 made of a spring plate is provided at the rear. Also, of the two front and rear struts 25a and 25b installed on both left and right sides of the vehicle body frame 24 on which the front wheel 1 is mounted, the front strut 2
5a, the cylindrical shaft 22 is fitted to provide a plurality of stages of the seedling mounting plate 21 so as to be pivotable forward about the vertical axis fulcrum P, and the fitting part 23 is connected to the rear support 2.
By elastically fitting to the seedling mounting plate 21
is fixed in an inclined position with the side of the fuselage 2 facing downward. As shown in FIG. 8, by bringing the machine 2 close to the ridge at right angles and rotating the seedling placement plate 21, pine seedlings A can be easily replenished from the ridge. When replenishing the seedlings on the table 13, by rotating the seedling placement plate 21 located above the pine seedlings A other than the ones to be taken out forward, the upper space is enlarged and the pine seedlings A can be easily taken out. It is structured as follows.

Each of the pine seedlings A has a handshake part 26a on one end side.
The seedlings are placed on the preliminary seedling stand 13 in a state where they are placed on a bent scooping plate 26.

The thickness a of the seedling placement portion of the scooping plate 26 is set to be the same as or greater than the thickness b of the handshake portion 26b, so that the seedling placement portion 5 can be easily removed from the preliminary seedling placement stand 5 as shown in FIG. After the pine seedlings A are supplied to the seedling rack 13, a large number of scooping plates 26 can be stacked and stored in a stable posture in a storage section 27 provided between the left and right spare seedling racks 5.

In the above embodiment, the seedling placement plates 21 are configured to be able to rotate individually around the vertical axis fulcrum P, but the entire preliminary seedling placement platform 5 on which the seedling placement plates 21 are vertically arranged side by side may be integrated. It may be configured to be able to pivot forward around the vertical axis fulcrum P.

In summary, the riding rice transplanter according to the present invention has a seedling planting device 4 connected to the rear of the machine, and a spare seedling rest 5 is provided on both left and right sides of the front of the machine. It is characterized by being configured to be able to pivot forward about a vertical axis fulcrum P provided therein.

That is, while the spare seedling stand 5 is disposed close to the boarding and operating section side so that the seedlings can be easily replenished to the seedling planting device 4, the machine body is not perpendicular to the ridge etc. when replenishing the spare seedlings. Since the stand 5 for placing spare seedlings can be placed close to the ridge in a posture and rotated around the vertical axis P to be positioned above the ridge, as mentioned above, the reserve seedlings can be replenished without entering the field. Since then, it has become easy and quick to do.
