Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter equipped with, for example, a seedling mount and a planting claw for continuously performing seedling work.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 3-18714, there has been a technique for mounting a mid-mount type fertilizer applicator on a traveling vehicle.

[0003]

In the above prior art, when the fertilizer hopper and the fertilizer feeding case are provided so as to be vertically movable, by fixing the hose joint to the air tank,
Although the transport hose can be supported at a predetermined position to eliminate problems such as disconnection of the hose, it is necessary to detachably connect the fertilizer feeding case and the hose joint. There is a problem that air and fertilizer leak from the joint joint and water gets in. In addition, by connecting the fertilizer feeding case to the air tank via the feeding auxiliary hose, the fertilizer can be smoothly fed from the fertilizer feeding case by the air blown from the air tank. When the feeding auxiliary hose is connected to the air tank on the outside, the left and right width of the air tank becomes long, and it is not possible to easily reduce the left and right width of the fertilizer applicator and reduce the weight.By providing a blower on one side of the air tank, , There was a problem that the fertilizer applicator could not be easily stored within the width of the seedling table rail in the planting section.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a fertilizer application hopper for storing fertilizer, a multi-row fertilizer feeding case for feeding fertilizer in the hopper, and an air tank for supplying air to the fertilizer feeding portion of the case. In the rice transplanter, which is provided with a hose joint that connects the fertilizer feeding case and the air tank to the transfer hose, a case joint that connects the outlet of the fertilizer feeding case and the inlet of the hose joint to each other is provided. The hole is provided with an elastic protrusion, and the gap formed between the outlet of the fertilizer feeding case or the inlet of the hose joint and the case joint is blocked by the protrusion, so the outlet of the fertilizer feeding case and the inlet of the hose joint. It is possible to eliminate the problems of air and fertilizer leaking from the joints of the Inlet resulting performed via the easy connection structure taken away against the junction of the output casing of the outlet and the hose joint,
It is possible to easily improve the handling operability such as raising and lowering the fertilizer feeding case.

Further, a fertilizer application hopper for containing fertilizer, a multi-row fertilizer delivery case for delivering fertilizer in the hopper, an air tank for supplying air to the fertilizer delivery section of the case, and a connection between the fertilizer delivery case and the air tank In a rice transplanter equipped with a feeding auxiliary hose, the feeding auxiliary hoses are connected to the air tanks inside the left and right fertilizer feeding cases, each of which has two rows as one unit. The weight can be easily reduced, and the width of the fertilizer applicator that attaches the air blower to one side of the air tank can be made shorter than the width of the seedling mounting table rails in the planting section. The fertilizer applicator can be easily stored within the width of the platform rail.

0) is attached laterally to the unit clutch lever (138), and with respect to the unit clutch lever (138),
The seedling vertical feeding member is substantially downward, the planting claw (17) is downward and rearward,
Since the fertilizer feeding cases (47) are located at the front, the respective clutch wires (130) (139) (14).
0) Twisting or bending during extension and seedling stand (16)
Of the clutch wires (130) (13)
9) While preventing deformation of (140), two wire stoppers (141) (142) are attached to one fertilizing clutch wire (130) to be connected to the unit clutch lever (138).
Fix each clutch arm (1 unit 2 sections)
27) (127) each wire stop (141) (142)
One fertilizer application clutch wire (130) is connected through the two fertilizer feed cases (47) (4) for one unit.
The feeding plates (84) and (84) of 7) are turned on and off at substantially the same time.

In addition, the unit clutch lever (13) is attached to the lever box (143) through a support shaft (144).
8) is attached so that it can swing in the left-right direction, and the lever (13
8) project above the box (143) and attach the seedling stand (1
6) By projecting the lever (138) on the upper end side and operating the lever (138),
2, each clutch wire (130) (139) in a solid line state
(140) moves about the fulcrum at substantially the same time and is pulled to the tension state of the virtual line position in the figure, and the planting claw (17) corresponding to the lever (138), the seedling vertical feeding member and the fertilizer feeding case (47). Is held off, and by operating the left unit clutch lever (138), the two left-sided planting claws (1
7) and the seedling vertical feeding member and the feeding plate (84) of the fertilizer feeding case (47) are turned on and off, and the central unit clutch lever (138) is operated, and the central two-row planting claw (17).
And the seedling vertical feeding member and the fertilizer feeding case (47) of the feeding plate (84) is turned on and off, and the right unit clutch lever (138) is operated, and the right side two planting claws (17), the seedling vertical feeding member and the fertilizer are fed. Feeding plate (8) of feeding case (47)
4) is turned on and off, and seedling planting operation and side row fertilization operation are performed in 2
It is configured to selectively stop by three unit clutch levers (138) as one unit of row, and make the number of unplanted rows and the number of planted rows match at the edge of the ridge to prevent wasteful consumption of seedlings and fertilizer. ing.
