Description

[Detailed Description of the Invention] The present invention relates to a riding rice transplanter in which a spare seedling stand and a seedling planting device are separately arranged before and after a control section.

This type of riding rice transplanter is equipped with a spare seedling stand, which minimizes the number of times the operator (driver) or the machine itself moves to the ridge each time seedlings are replenished, making it easier to improve overall planting work efficiency. However, the following problems still occur in the work of supplying seedlings from the preliminary seedling stand to the planting device.

That is, when replenishing spare seedlings, first take out relatively heavy spare seedlings placed and stored on the spare seedling racks located on one side of the front and back of the control section in a horizontal or almost horizontal position, and then While holding the seedling in a horizontal position, turn the body toward the opposite side of the control section and carry it onto the seedling planting device, and then place the spare seedlings on the seedling stand of the seedling planting device. This is a problem that requires a great deal of effort and effort to replenish the seedlings, as this must be repeated for the number of rows to be planted.

Therefore, as a method to solve the above-mentioned problems, for example, as disclosed in Japanese Utility Model Application Publication No. 55-38888, seedlings are placed on the fuselage at the rear of the spare seedling storage section and on both sides of the control section. A structure was considered in which the slide guide part was provided in a fixed position and a turntable for transfer was provided in the front part of the seedling stand.

However, in the above-mentioned improved structure, since the seedlings are fed by sliding them in the front and rear directions, slide guide parts in a fixed position are required on both sides of the control part, which makes it difficult to operate the control part. This has the disadvantage that the living space is extremely limited, making it difficult to operate the vehicle, and it also becomes a nuisance when the driver gets in and out of the vehicle.

The purpose of the present invention is to eliminate the above-mentioned problems.

The characteristic structure of the riding rice transplanter according to the present invention, which has been made to achieve the above object, is that in the riding rice transplanter described at the beginning, spare seedlings are placed and supported between the stand for placing seedlings and the seedling planting device. A transfer device for transferring the seedlings to the seedling planting device side is provided, and the transfer device connects a plurality of arm members via bendable and extensible joints, and transfers the seedlings to the seedling planting device side, and connects a plurality of arm members via flexible joints, and transfers the seedlings to the seedling planting device side. The placing section is configured to be movable horizontally, vertically, and in a composite direction within a range extending between the preliminary seedling rest and the seedling planting device, and is configured to be movable in the horizontal direction, vertical direction, and combined direction thereof, and to It is equipped with a hanging means that applies a biasing force in the lifting direction, and its action,
The effects are as follows.

That is, when feeding the seedlings on the preliminary seedling pedestal to the seedling planting device, the joints connecting the arm members are bent and stretched while the seedlings are transferred from the preliminary seedling pedestal onto the preliminary seedling pedestal, After the preliminary seedling placement section is moved horizontally onto the seedling planting device, the seedlings are taken out from the preliminary seedling placement section and supplied to the seedling planting device. During the operation in the horizontal direction, the preliminary seedling placement section can be moved against the weight of the seedlings by the biasing force of the hanging means while maintaining the preliminary seedlings in a suspended state. becomes.

As a result, while it is possible to replenish seedlings easily with less effort and without any accidental falling off, there is no need to provide any fixed guide parts on the sides of the control part, and a sufficiently large This enabled us to secure space for maneuvering and getting on and off the aircraft.
