A riding rice transplanter is a traveling vehicle that has front wheels and rear wheels, is equipped with a seat, and can be operated and operated by a worker riding on it, and is equipped with a rice transplanting section that can be moved up and down. The running vehicle of a riding-type rice transplanter for seeds has an engine, transmission, seat, etc. built into the body frame, so the center of gravity of the vehicle is relatively high, making running unstable, and the conventional body structure Therefore, the structure of how the rice transplanting section was attached to the traveling vehicle had to be complicated, and the machine as a whole had to be large.

The present invention has been proposed in order to solve the above-mentioned problems, so that the body structure of the traveling vehicle can be configured to have a low center of gravity, the rice-transplanting section can be easily attached, and the ground clearance of the bottom of the rice-transplanting section can be reduced. The purpose is to provide a compact riding rice transplanter that has a sufficiently high angle, has a low center of gravity, and is highly adaptable to wet fields.

For this purpose, the present invention relates to a traveling vehicle, in which a transmission case is disposed between a front wheel and a rear wheel, a front wheel transmission frame is provided at the front portion of the transmission case that extends obliquely upward, and a front wheel transmission frame is provided at the rear portion of the transmission case. The planting part transmission frame extends horizontally toward the rear so that it has a rectangular shape when viewed from the side, so that a heavy transmission case can be installed at a low position. It is characterized by a pair of rear wheel transmission cases that can swing downwards.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the drawings, FIGS. 1 and 2 are a side view and a plan view showing the entire riding rice transplanter according to the present invention, in which A is a running vehicle and B is a rice transplanting section installed at the rear thereof. .

In the traveling vehicle A, a transmission case 1 is disposed between a front wheel 2 and a rear wheel 3, and in the present invention, a front wheel transmission frame 4 is disposed diagonally forward and upward from the front center of the transmission case 1 as a base body. Furthermore, a planting portion transmission frame 5 extends horizontally from the rear center toward the rear, and these front wheel transmission frames 4. Transmission case 1. The planting part transmission case 5 constitutes a suspended frame that has the following shape when viewed from the side. At the front end of the front wheel transmission frame 4, the front wheel 2 is supported so that it can be rotated via a transmission case 7 with a support arm, and a steering shaft 8 is mounted on the L side of the front end. Equipped with a control handle 9 via. Further, on both sides of the transmission case 1, rear wheel transmission cases 6 are arranged so as to form a planar gate shape with respect to the transmission case 1. The wheel transmission case 6 is designed so that it can swing up and down from the rear end using the front end as a pivot point. Each rear wheel transmission case 6 is provided with a swinging member 19 protruding in one direction from the pivot portion at the front end, and the tip of the rear wheel transmission case 6 is connected to a piston of a hydraulic cylinder 18. It is connected to the tip of the rod and swings up and down by the expansion and contraction of the hydraulic cylinder 18.In addition, inside each of the front wheel transmission frame 4 and the rear wheel transmission room 6, there is a transmission as described later. Front wheel drive transmission system that reaches the front wheel 2,
The rear wheel drive transmission system leading to the rear wheels 3 is configured to transmit rotational driving force to the front wheels 2 and rear wheels 3 through internal grooves.

Located immediately after Juki Transmission 1 Index 1,
An engine 10 is mounted on the planting section transmission frame 5). Further, a saddle-shaped seat 11 is disposed extending from an upper position of the T-engine 10 to the front end of the heavy-wheel transmission frame 4, and is inserted under the seat 11. J, sea urchin C fuel tank 12 is fixed with bracket 13 - [Constellation 1', 11 h: G, L on the right,

Continuing from 4 and 7, there is a deck 1 (i) in the lower front of seat 11.
A li is provided, so that the sound of the work can be heard by stepping on the deck bar 15 and sitting in the seat 11.

In the running vehicle A, a rice transplanting section B is attached to the rear end of the planting section transmission frame 5 via a pivot shaft 17 so as to be tiltable back and forth. An interlocking rod 2 is connected between the swinging arm 19△ connected to the hydraulic cylinder 18 and the machine frame 20 of the rice transplanting section B.
1 is spread over the rice-transplanting section B, and the rice-transplanting section B is tilted about the pivot shaft 17 via the swing arm and the interlocking rod 21 by the expansion and contraction of the oil tank cylinder 18, and the rice-transplanting section B is moved against the rice field. Relative relationships (e.g. pitching correction) can now be adjusted.

The rice transplanting section B has the same structure as the conventionally known No. 6, and is arranged opposite to a seedling mounting table 28 that reciprocates in the left and right direction with a predetermined stroke and a seedling outlet of this seedling mounting table 28. It has a sagging shrubbery 2a), and is equipped with a float 30 on the lower side that can be tilted up and down, so that it can slide on the rice field 1-. As seen in conventional rice transplanters, a hydraulic switching valve 27 is provided on the float 30 to issue a switching signal in response to the vertical movement of the float. When the car △ tilts, the switching valve 2 is activated by the upward movement of the float 30 due to the tilting.
7 is activated to operate the hydraulic cylinder 20 on the side of the traveling vehicle to move the rice-transplanting section B up and down, and the rice-transplanting section F3 is moved up and down.
It is the same as the conventional one in that it is constructed so that it can always slide with the front surface facing the front and the Y.

The transmission system of the riding rice transplanter in this embodiment is, for example, as shown in FIG.
3 and a hydraulic pump 34 (this hydraulic pump supplies pressure oil to the hydraulic cylinder 18), and the transmission transmission system 33 passes through a gear tooth width row as in the well-known 1, and is then transmitted to the front wheel transmission shaft 1. ．． The transmission system 36 for driving the front wheels is connected to the front wheels 21 via the transmission system 3j) for driving the front wheels installed inside the node 4, and the transmission system 36 for driving the rear wheels installed internally inside the rear wheel transmission case 6.
Power is transmitted to the rear wheels 3 via the respective rear wheels 3. In addition, power is branched from the transmission transmission system 33 to another power transmission system 37 for driving the rice transplanting section, which is installed inside the planting section transmission frame 5, and extends rearward. 38, power is transmitted to an implant drive mechanism 39 and the like.

In the configuration of the traveling vehicle A as described in 1., (1) a front wheel transmission frame 4 extending from the front and rear of the transmission case 1 as a base body; Since the planting part transmission frame 5 also serves as the vehicle body frame, the frame structure of the vehicle body can be simplified.

■ Also, the front wheel transmission frame 4 extends from the front and rear of the transmission case 1 as a base body. The vehicle body frame composed of the transmission frame 5 is shaped like this when viewed from the side, and the transmission case 1 in the center
Since the transmission case 1 is located at a low position in the bent portion, the transmission case 1, which is relatively heavy, is located at a low position and has a low center of gravity.

(■ In addition, traveling car A has a transmissi J/f-
1-1 the planting part transmission frame 1) extending rearward from the
The rice-transplanting section B is connected to the rice-transplanting section B via this planting section transmission frame 5
Since it can be directly mounted, E (letfi working part F working part 3
It becomes easier.

■ In addition, the pair of left and right rear wheel transmission cases 6 arranged on both sides of the transmission case 1 are designed to be able to swing downwards, so that the rice-transplanting section B is protected from the effects of unevenness of the tiller while driving. By moving the rear wheels 3 downward, the height of the bottom surface of the rice transplanting section B can be increased by 1 minute).

Thus, according to the present invention, the comparatively heavy weight engine case is placed between the front wheels and the rear wheels to achieve low IE.
By placing RQ '7, the total C running length is 11Φ.
In addition to improving driving stability by lowering the center of gravity of the vehicle, the vehicle body structure can be greatly simplified, and the rice-planting work section can easily attach the rice-transplanting section to the traveling vehicle. By swinging, it is possible to provide a compact riding rice transplanter with a low center of gravity that is highly adaptable to wet fields.

115. In the embodiments of the present invention, the illustrated riding rice transplanter is a one-wheel type with front wheels, but it goes without saying that it may be configured with four wheels instead of the front wheels.
