Description

[Detailed Description of the Invention] The present invention relates to a walk-behind rice transplanter in which a preliminary seedling stand is arranged above the left and right wheels, and a pair of left and right tanks for fertilizer or chemicals is provided.

Conventionally, in the above-mentioned rice transplanting machine, the left and right tanks were arranged on the left and right sides of the preliminary seedling stand to prevent the center of gravity of the machine from becoming high due to the weight of fertilizers and chemicals. However, the tanks are an obstacle that makes it difficult to see the wheels from the control position, making it difficult to judge where the wheels will pass in front of the aircraft, and because the tanks are far away from the left and right center of the aircraft. If there is a difference in the rate of decrease of the contents of the left and right tanks, and the weight difference between the left and right tanks becomes large, this weight difference will cause a large force to tilt the aircraft left and right, making it difficult to control the aircraft. There were drawbacks such as making it difficult to use.

The purpose of this invention is to lower the center of gravity of the aircraft as much as possible by improving the arrangement of the left and right tanks.
The objective is to enable easy visibility from the steering position of the wheels, and to suppress tilting of the aircraft due to the difference in the remaining contents of the left and right tanks.

The characteristic configuration of the present invention is that, in the above-mentioned walk-behind rice transplanter, each of the tanks is arranged below the preliminary seedling stand, inside the wheels, close to the wheels, and lapped with the wheels when viewed from the side. This is due to the fact that it was placed in such a way that it

In other words, by placing the tank close to the wheel on the inside of the wheel, the tank can be placed close to the wheel when viewed from the side by utilizing the gap between the wheel and the machine without changing the placement level of the spare seedling stand. Because it can be placed at a low level where it wraps, it is possible to prevent the center of gravity of the machine from becoming too high due to the weight of fertilizers, chemicals, and spare seedlings. It is possible to easily see the aircraft from its position while remaining in the operating posture, and the tank is placed as close to the left and right center of the aircraft as possible to minimize the moment that acts to tilt the aircraft due to the weight of the contents of the left and right tanks. It was made smaller, and overall the aircraft was easier to control.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a pair of left and right wheels 1a, 1
b. Planting four seedlings in parallel in the lateral direction of the aircraft at the rear of the self-propelled aircraft, which has a spare seedling stand 4 placed above the engine 2, the control handle 3, and the left and right wheels 1a, 1b. The arms 5 and the seedling planting arms 5 are provided with a seedling stand 6 for supplying seedlings, and three ground floats 7 are attached to the lower part of the self-propelled aircraft in parallel in the lateral direction of the aircraft. , a walk-behind rice transplanter capable of planting four rows.

A pair of left and right wheel transmission cases 8, 8 are installed so as to swing up and down around the axis _P1 of the aircraft body, and are also moved up and down in opposite directions relative to the aircraft body using the swing arm 9, seesaw link 10, etc. The structure is such that the machine body is oscillated in such a way that the machine body is maintained in a posture parallel to or almost parallel to the mud surface when viewed from the front and rear directions, regardless of the horizontal inclination of the tiller.

As shown in FIGS. 1 to 3, the left and right pair of powder fertilizer tanks 11a and 11b are installed below the preliminary seedling stand 4, inside the wheels 1a and 1b, and close to the wheels 1a or 1b. At the same time, the four groovers 12 are arranged so as to overlap the wheels 1a and 1b, which are at the standard height relative to the aircraft, in a side view.
are attached to the float 7 or the aircraft body in a state in which they are arranged in parallel so that they act separately on the mud surface on the sides of the four rows of planted seedlings, and the two furrowers 1 on the left side are
2, 12 from the left tank 11a, and the two right groovers 12, 12 from the right tank 11b.
The tanks 11a and 11a are respectively supplied with fertilizer.
The screw-type fertilizer feeder 13 of 11b and the furrower 12 are connected by a hose 14, so that fertilization work can be performed in conjunction with the planting work.

As shown in FIGS. 2 and 3, a pair of openings 15a, 15b and a funnel part 1 are provided in the preliminary seedling stand 4 to input fertilizer into the left and right tanks 11a, 11b separately.
6a and 16b, so that fertilizer can be supplied to the tanks 11a and 11b while the spare seedling stand 4 is used as a support for fertilizer containers such as bags, and a seedling scoop is used to carry the spare seedlings during work. A plate 17 is configured to cover the input ports 15a and 15b. Furthermore, the preliminary seedling stand 4 is constructed so that it can be swung apart from the tanks 11a and 11b around the axis _P2 , and for cleaning the inside of the tanks, etc. The spare seedling stand 4 is designed to be removable.

FIGS. 4 and 5 show another embodiment of the preliminary seedling rest 4 and the fertilizer tanks 11a, 11b, in which the preliminary seedling rest 4 and the fertilizer tanks 11a, 11b are integrally formed, and the tanks 11a, 11b are pivoted. It is configured so that it can be swung up against the aircraft around the core _P3 and the remaining fertilizer in the tank can be taken out. Further, the preliminary seedling stand 4 is provided with a funnel portion 18 for taking out and collecting residual fertilizer.

The present invention can also be applied to a rice transplanter equipped with a chemical tank so that various chemicals for weeding and the like can be supplied to the field.
