There is. This fertilizer applicator is fertilizer fed from the hopper
Is flown by the wind power of the blower deployed on the left side of the aircraft
A relatively long transfer path to the grooved device
It is configured to transfer fertilizer well without clogging
The [0003] SUMMARY OF THE INVENTION A fertilizer application system is
Because they are driven together, fractional planting at the brink
As shown in the above publication, seedling planting
The mechanism, seedling vertical feed mechanism and fertilizer feed mechanism are added at once.
An operation structure for cutting is required.
The engagement operation structure was not disclosed. [0004] The present invention provides a seedling planting mechanism, a seedling vertical feed mechanism and a fertilizer.
A structure that turns on and off the feeding mechanism at once, and a feeding machine
The purpose is to simplify and rationalize the drive structure
The [0006] [Means for Solving the Problems] 〔Constitution〕 The first invention is a hopper for storing powder particles and the hopper
Feeding mechanism that feeds the granular material sent from

And an inner gear linked to the longitudinal feed clutch.
UnpleasantAnd one end is fixed and the other end isGranular clutch
With an outer wire linked to the
Because it is composed of
By workGranular clutchIs pressed and 畦
The clutch and the longitudinal feed clutch are pulled
Become. Therefore, by pushing the outer wire,Powder
clutchHowever, when the inner wire is pulled,
Switch and vertical feed clutch are each turned off (or turned on).
If you set the operation direction to be
The clutch can be turned on and off simultaneously. And
For this purpose, the interlocking connection structure has one Bowden wire.
A simple configuration is sufficient. [0012] [0013] [0014] [0015] [0016] [Effect] In the rice transplanter according to claim 1, the outer wire and

Claims (1)

(57) [Claims] [Claims] [Claims] [Claims] [Claim 1] A hopper for storing powder particles, a feeding mechanism for feeding the powder particles sent from the hopper by a predetermined amount, and a seedling of the fed powder particles It is a granular material supply device of a rice transplanter provided with a granular material transfer path to be sent to a grooving device equipped in a planting device, and a granular material clutch that interrupts power to the feeding mechanism,
While providing a saddle clutch that interrupts the power to the planting mechanism and a vertical feed clutch that interrupts the power to the seedling vertical feed mechanism, corresponding to some minority of all planting strips,
A single operating tool capable of operating these three types of clutches at once or through the interlocking mechanism is provided, and the interlocking mechanism includes the operating tool and the saddle clutch, and
And an inner gear linked to the longitudinal feed clutch.
And ear, one end of which is fixed, and the powder or granular material class is the other end
Granular material supply device for rice planting machine that is constituted by Bowden wire and a outer wire being operatively connected to the pitch.
