Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a riding type rice transplanter, and a conventional rice transplanter of this type has a structure in which a rice transplanter can be raised and lowered with respect to a traveling vehicle body provided with a control seat. Met.

For this reason, since the rice transplanting device is adjusted up and down depending on the depth of the field, the position of the seedling tank of the rice transplanting device relative to the operator's seat changes, making replenishment of seedlings difficult.

This invention aims to eliminate the above-mentioned drawbacks and has taken the following techniques and technical means.

That is, a seedling is placed on a running vehicle body (A) having front wheels (3) and rear wheels (4), a control seat 0υ, and a seedling that is tilted so that the front side is close to the rear of the control seat and the rear side is at the bottom. A working machine (B) consisting of a tank OI, a seedling planting mechanism for dividing and planting seedlings from the rear end of the seedling tank, and a rice transplanting device a41 having a soil leveling float at the bottom (a). The structure is such that it can be raised and lowered.

One embodiment of this invention will be described in detail based on the drawings. (A
) is the running vehicle body, with chain cases (2) extending rearward and downward on both left and right sides of the running case (1), on which the rear wheels (4) are supported. 011 car @ on the fork (5) that can rotate around
(3), and furthermore, the traveling transmission case (1
) and place the engine stand (6) on the rear of the engine (7).
), power is transmitted from the engine (7) to the traveling transmission case (1) via a transmission belt (8), and the rear wheels (4) are driven so that the vehicle can run on its own.

The work aircraft 03) is made up of a frame (9) with a pilot seat 0υ attached and approximately V-shaped in side view, left and right step frames (LOA), and a central bulge (lOb). a front frame 0 fixed to the front side of the frame (9), a rice transplanting device 0 attached to the rear side of the frame (9) via a connecting frame α, and the front frame 0.
2 and a rotatably provided handle 0υ.

This handle 0υ is universally joined to the vertical shaft 06 which is spline-fitted to the fork (5).
(It is attached via +71.

The rice transplanting device 04) includes a seedling tank OI which is installed on the top of the planting mission case 0 barrel so that the front side is at the top and can be moved back and forth from side to side, and a seedling tank OI that faces the rear lower end of the seedling tank OI. (a+)・
It consists of (a).

This rice transplanting device 04) is attached to the connecting body θ3 via a rolling shaft (E).

(c) and (c) are the front and rear links, respectively, and the traveling vehicle body (
This link connects the working machine (B) to A), and both links are parallel links.

(c) is a hydraulic cylinder device, cylinder (26a)
The side is pivotally connected to the traveling transmission case (1), and the piston (
(8) is connected to the frame (9) of the work machine (B), and this hydraulic cylinder device is configured to move the work machine (inside) up and down relative to the traveling vehicle body (A). (A) is a hydraulic control lever that allows the switching valve of the hydraulic cylinder device to be freely switched and operated.

(c) is the propeller shaft and the traveling transmission case (
1) and the transmission shaft of the J Mission Case A, which can be expanded, contracted, and bent freely.

(A) is a thalassotile lever that manually cuts off the power on the 0 side of the rice transplanting device. (2) indicates the change lever.

0υ is a hydraulic switching valve, which is installed between the central ground leveling float @]) and the support rod 112 integrated in m (=J mission case 08), and controls the vertical movement of the front part of the ground leveling flow) @I). Due to this, the valve 01) is switched so that the ground pressure of the ground leveling flow () &]) is always within a certain range suitable for seedling planting + J. (g) indicates the pump, trowel indicates the oil tank, and 09 indicates the relief valve. In addition, (c) shows a preliminary seedling tank.

Next, to explain the function of the upper side, first, seedlings are planted in the field by placing the seedlings in the seedling tank 0 and then using the engine.
7) Rotate each part.

Then, the rear wheels (4) are transmitted and rotated, and the traveling vehicle body (A)
is moved forward with its front wheels (3) and rear wheels (4) touching the tiller. On the other hand, on the rice transplanting device aa side, the soil leveling floats 1) and (a) are grounded on the surface of the field and are towed, while the seedling tank 0 and the seedling planting body holder are moved back and forth from side to side. Seedlings are divided and engaged to create a soil leveling float.
- Planting can be done on the topsoil leveled in (a).

In this way, while planting seedlings, when the tilling platform is shallow, the front part of the soil leveling float &1) in the center becomes a bit floating, and the ground pressure decreases, and as a result, the hydraulic switching valve 0υ moves in the direction of the arrow p). It will be switched. For this reason, the piston (26b) of the hydraulic cylinder device (g) is pulled into the work machine CB.
) descends and the ground pressure of the ground leveling float 0υ becomes appropriate, its downward movement stops and that state is maintained.

Conversely, when the tiller becomes deeper, the soil leveling float Qυ is pushed up, so the ground pressure increases, and the hydraulic switching valve OD is switched in the direction opposite to the arrow K), causing the piston (26b
) protrudes and raises the work machine (B), and the ground leveling flow 10
This will keep the ground pressure constant.

In this manner, in this embodiment, the working machine (B) is not automatically controlled to raise and lower, but follows the depth of the tiller.

During seedling planting, when replenishing the seedling tank θ, take out the seedlings in the preliminary seedling tank and replenish them into the seedling tank 0. At this time, the position of the seedling tank with respect to the control seat (lυ) is always at a predetermined height position regardless of the depth of the tiller, so it is extremely easy to replenish seedlings.

As described above, since this invention has the above-mentioned configuration, even if the working machine side is moved up and down with respect to shallow or deep plowing platforms, the vertical height positions of the control seat and the seedling tank will not be disturbed, making it extremely easy to replenish seedlings. It has a unique action and effect that is said to be easy to perform.
