Description

[Detailed Description of the Invention] This invention relates to a riding-type rice transplanter, and more specifically, to a riding-type rice transplanter that is provided with a multi-tiered stand for preliminary seedlings at the rear of the vehicle body.

A riding rice transplanter has an engine mounted on a self-propelled body with front and rear wheels, and transmits the output of this engine to the drive wheels. However, rice planting is carried out while the vehicle is traveling while seated.

Such riding-type rice transplanters are used for rice planting in a wide range of fields, and because they are configured to plant multiple rows in one run, they consume a large amount of seedlings.

Therefore, a device has been devised so that a spare seedling stand is installed on the vehicle body so that rice planting can be carried out continuously while replenishing seedlings.

However, the so-called seedling replenishment work, in which the spare seedlings on the spare seedling table are transferred to the seedling table of the work machine for planting, is quite laborious and troublesome. However, in order to make it lighter, it is necessary to install a spare seedling stand close to the seedling stand of the work machine for planting.

However, during planting, the seedling loading platform of the work machine is lifted up during the seedling loading operation, and its locus of movement is not a straight line but a complex curved trajectory, so if the preliminary seedling loading platform is moved rearward. , which may impede the movement of the seedling stand.

In a riding rice transplanter that increases the amount of spare seedlings by installing a multi-stage reserve seedling platform, the tip of the trajectory of the seedling platform enters toward the front of the vehicle body, so there are In particular, we must expand our Tsuji intention.

Therefore, this invention was developed to provide a multi-tiered preliminary seedling mounting table in a riding rice transplanter, so that the mounting table does not interfere with the lift-up movement of the working machine during planting, and also allows the planting to be done at an angle to the working machine. The seedling mounting table set up in this manner faces each of the multi-tiered reserve seedling mounting tables in almost the same posture as when planting seedlings, and in this position, the seedlings are replenished from each of the above-mentioned reserve seedling mounting tables. At the same time, the platform, which has been replenished with seedlings, returns to the position at which it was planted in substantially the same posture as described above, so that the seedling supply can be carried out reliably and easily.

The details of this invention will be explained below with reference to the attached drawings.

First, in the figure, reference numeral 1 indicates a vehicle body, and this vehicle body 1 is equipped with steering wheels 2 and drive wheels 3. A handle 4 is provided at the top and front of the vehicle body 1, and an operator's operating seat is placed so as to face the handle 4. 5 is placed.

An engine (not shown) as a power source is mounted behind the operating seat 5, and in a space behind the engine and above the drive wheels 3, a multi-stage preliminary seedling mounting table 6 is formed.

Further, at the rear of the vehicle body 1, a planting machine 7 is attached via a link mechanism 71 forming a parallelogram, and the planting machine 7 includes a float 72, a planting body 73, and The seedling mounting table 74 is configured to supply seedlings to the planting body 73, and the upper end of the seedling mounting table 74 is inclined toward the vehicle body 1 side.

Reference numeral 75 denotes a cylinder unit for lifting up the work machine 7, which gives movement around the pivot point of the link mechanism 71 to the link mechanism 71 so that the work machine 7 can be lifted up. It has become.

This planting is carried out using the working machine 7, especially the tip of the seedling stand 14.
The movement trajectory from the planting operation (lowering) to the lift-up via the link mechanism 71 is as shown by the curve T in the figure.

When forming the multi-tiered preliminary seedling mounting table 6 on the vehicle body 1, the rear end 61a of each preliminary seedling placing table 61 is arranged along the movement locus curve T, and is mounted on the mounting table 6. When the seedlings P stored in the seedling stand B are transferred to the seedling stand 74 during replenishment work, the tip of the seedling stand T4 is placed on the seedling stand 61.
It is possible to get very close to the rear end 61a of the rear end 61a.

Therefore, during planting, seedlings are supplied to the seedling platform 74 of the work machine, so when this is lifted up, the tip 7 of the seedling platform 74 is
Since the rear end 61a of each preliminary seedling mounting table 61 is located on the curve drawn by 4a, by appropriately selecting the amount of lift-up, the seedling can be placed on one of the multi-tiered preliminary seedling placing tables 6. The tip 74a of the stand 74 can be brought closer.

As is clear from the above explanation, according to the riding-type rice transplanter of this invention, a lift mechanism is attached to the rear end of the self-propelled vehicle body to allow the rice transplanter to be raised and lowered, and a parallel Constructed of quadrilateral links, planting can be done up and down without changing the posture of the work machine.In addition, at the rear of the vehicle body, a multi-tiered reserve seedling platform is formed, and the rear end of this reserve seedling platform is When planting using the lift mechanism, when the work machine is raised, the movement path of the tip of the seedling stand installed at an angle on the work machine is followed, and the tip of the seedling stand and the rear end of each spare seedling stand are connected. □□□) The seedling mounting table maintains a constant tilted posture and is in communication with the rear end of each of the multi-tiered spare seedling mounting tables. Spare seedlings can be replenished by simply sliding the seedlings onto the seedling tray side, and when replenishing seedlings, the spare seedlings can be moved in an almost constant sliding state on both the upper and lower preliminary seedling trays. This allows for reliable and easy supply of seedlings.
