Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a preliminary seedling loading device for a riding rice transplanter.

Prior Art Conventionally, a support frame that can be rotated around a vertical axis is provided on both left and right sides of the front side of the towing vehicle of a riding rice transplanter, and a stand for placing spare seedlings is attached to this support frame. There is a preliminary seedling mounting device that is equipped with a switching device that switches the seedling mounting platform between a rotating state and a locked state in which it does not rotate. but,
The switching means for switching between a locked state and an unlocked state of the rotation of the seedling platform has been a foot pedal or has been provided only at one location on the front or rear side of the single rotation member.

Problems to be Solved by the Invention With the conventional device, when loading seedlings onto the preliminary seedling platform from the front side of the towing vehicle, the driver or an assistant riding on the towing vehicle must equip the preliminary seedling platform. I couldn't place spare seedlings side by side in the front and back unless I unlocked the rotation lock on the frame and rotated it.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a control handle 10 that is disposed near the front at the left-right center position, and a control seat 11 that is arranged at a predetermined distance behind the control handle 10. A step floor 13 is provided continuously from the front side on both left and right sides of the control handle 10 and on both left and right sides of the cockpit seat 11.
In a riding rice transplanter, a rice transplanter 15 is attached to the rear of a riding tractor 1, which is also provided with a step floor 13a at the front of the tractor 1, via an elevating mechanism 19. A support frame 39 is provided that is rotatable around an axis in the vertical direction, and a seedling mounting table 40 that can place two seedlings side by side in the front and rear directions is provided on this support frame 39 so that spare seedlings can be stored and taken out from the front and back. The seedling mounting table 4 is installed in multiple upper and lower stages.
A locking mechanism for preventing rotation is provided at a position where the spare seedlings placed at least a are lined up one after the other, and switching operation levers 45a and 45b for switching this locking mechanism between a locked state and an unlocked state are rotated. This preliminary seedling mounting device for a riding rice transplanter is provided integrally with a movable member and is configured at both front and rear positions in a locked state.

Functions and Effects of the Invention According to the present invention, when one of the switching operation levers 45a, 45b located on the front side or the rear side is operated, the rotation lock of the preliminary seedling mounting table 40 is released and the preliminary seedling loading table on the front side is freely moved. It is possible to transfer between the side and the rear side of the spare seedling loading table, and of course when replenishing seedlings to the spare seedling loading table 40, the spare seedling loading table can be transferred to the seedling loading table 17 side of the rice transplanting machine 15. Transfer work to supply 40 seedlings can be done easily.

In the upper configuration, one or two assistants ride outside the driver during rice transplanting. And rice transplanting machine 15
Each seedling mounting table 17 and spare seedling mounting table 40.40.・・・
Land leveling float 27 of rice transplanting machine 15 with seedlings loaded on...
The rice transplanting machine 15 is lowered so that it touches the surface of the topsoil of the paddy field, and while being propelled by the towing vehicle body 1, power is transmitted to each part from the towing vehicle 1 side.

Then, the seedling platform 17 reciprocates left and right to supply seedlings one by one to a transplanting device 18 located at the lower part of the rear end, and the transplanting device 18 plants the seedlings one after another on the topsoil surface of the paddy field.

In this way, the rice planting work is carried out.
When the number of seedlings loaded in the holder becomes low, an assistant, while seated on the auxiliary seat 30 or standing up, scoops out the seedlings in the seedling box loaded on the preliminary seedling tray 40 located in front. Scoop out the rice using a removing plate (not shown) and use the rice transplanting machine 15.
The seedlings are fed onto the seedling stand 17. In this case, rice transplanting work is usually carried out without interruption. Also, the first
If the seedlings placed on the rear seedling platform 40 in the figure and the second time have already been used and the seedlings are left on the front seedling platform 40, the switching operation lever 45a on the near side is pressed. When the lock plate 46a is rotated upward, the locking plate 46a is removed from the locking recess (A) of the bowl-shaped body 36, and the connecting protrusion (A) of the connecting body 43a is removed.
Push down the protrusion (d) of the linking body 43b with c) to move the other switching operation lever 45b upward, and the lock plate 46b comes off from the locking recess (b) of the bowl-shaped body 36, and the preliminary seedling stand 40
is free to rotate around the support shaft 33. Therefore, when the switching operation lever 45a is turned to the right or left while swinging up, it rotates 180 degrees, and the preliminary seedling platform 40 located at the front rotates to the rear, and the lock plates 46a and 46b are locked. The rotation is stopped by engaging with the recesses (b) and (c).

Therefore, the seedlings that were previously mounted on the seedling platform 40 on the front side are now located on the rear side, so it is very easy to scoop up the seedlings on the seedling platform 40 and place them on the seedling platform 17 of the rice transplanting machine 15. can be supplied to

In addition, when loading seedlings together with seedling boxes on the preliminary seedling platform 40, the tractor 1 is brought close to the ridge of the field, and the supply person is on the ridge side and operates the switching operation lever 45a or 45b.
By rotating the preliminary seedling mounting table 40, seedlings can be easily replenished.
