Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer
Riding rice transplanter with fertilizer application device and riding vegetable with fertilizer application device
Equipped with fertilizer application equipment such as a transplanting machine and a fertilizer application equipment
The present invention relates to a riding type seedling transplanter. [0002] Conventionally, an upper part of an airframe equipped with a front wheel and a rear wheel is provided.
A seat is provided, and the fertilizer hopper of the fertilizer
There is a riding type rice transplanter with a fertilizer device provided with an outlet. [0003] Conventional riding with a fertilizer application device
The rice transplanter is connected to the fertilizer hopper of the fertilizer
Because it has a protruding part, the total length of the aircraft is longer,
I could not get a riding rice transplanter with a small fertilizer,
There was a problem in maneuverability in the field. [0004] The above-mentioned problems should be solved.
In addition, the invention according to claim 1 is characterized in that
Riding type seedling planter with fertilizer device equipped with fertilizer device 5
And below the covers 30 and 35 covering the body of the traveling vehicle body 2
The fertilizer hopper 60 of the fertilizer applicator 5 and the fertilizer in the fertilizer hopper 60
Feeder 61 for feeding the raw material and the fertilizer fed from the feeder 61
Such as a blower 67 that sends out air to convey the air
It is a riding type seedling planter with a fertilizer device with a body part.
is there. Therefore, the space below the covers 30 and 35 that cover the body
The fertilizer hopper 60 of the fertilizer application device 5 and the fertilizer
Feeder 61 for feeding the fertilizer in the feed hopper 60 and the feeder 6
Air was sent to convey the fertilizer taken out from 1
By arranging the main body such as the blower 67,
To obtain a riding-type seedling planter with a small fertilizer
And, of course, with a lower weight center than before
In the field, maneuverability in the field is improved,
Work. Further, the main body of the fertilizer application device 5 covers the body.
Since the upper part is covered by the covers 30 and 35,
The fertilizer hopper 60 and the feeding part 61 were very wet by rain etc.
Can be prevented from spreading, and the fertilizer is moistened and the fertilizer is properly fed.
Good fertilization can be prevented
Work can be done. According to the present invention, the total length of the fuselage is short.
Obtaining a riding type seedling planter with a small fertilizer with a low center of gravity
And improved maneuverability in the field, resulting in higher efficiency
Work can be performed. Therefore, the problem of the conventional example can be appropriately solved.

are doing. These feeding rolls 73A and 73B have an outer periphery
Are formed with groove-shaped recesses 74,.
Square shaft portion 75a of a common feeding shaft 75 provided in
(Square axes) so as to rotate together.
The feeding rolls 73A and 73B rotate in the direction of the arrow in FIG.
As a result, the fertilizer dropped and supplied from the fertilizer hopper 60
It is accommodated in the concave portion 74 and is fed downward. Both payout rows
The fertilizer fed out by the nozzles 73A and 73B
It is discharged from the outlet 61a. Concave portions of the feeding rolls 73A and 73B in the illustrated example.
Is six, and the phases of the two concave portions are different.
You. For this reason, the concave portions of both the feeding rolls 73A and 73B intersect.
The fertilizers are fed out from each other and discharged from the discharge port 61a.
The amount of fertilizer used is equalized over time. either
Remove the feeding roll from the feeding shaft 75 and change the phase appropriately.
By reattaching, the two feeding rolls 73A, 73B
The phases of the concave portions can be made equal. Now on the field
It can be applied to the case where the fertilizer is sprayed in the form of dots. A recess 74 is provided inside the feeding portion 61.
