Then, the left fertilization pump 27 and the right fertilization pump 28
The fertilizer sucked in is sent to the left fertilizing nozzle 30 and right fertilizing nozzle 33 through the fertilizing pipe 31 and the fertilizing pipe 34, and is sent to the grooves formed deep in the soil by the rotary blade 47 and the groove cutting blade 46. fertilized within.

In addition, the left fertilizer tank 22 and the right fertilizer tank 23
is located above the row spacing 25 of the erect plants 24 in the field (Fig. 3).
It is possible to move forward while weeding the upper ends of the plants 4, and therefore it is very easy to move forward and perform fertilization work, and the standing plants 24 are not trampled over.

(Effects) Conventionally, there has been a known method in which a fertilizer tank is provided in the upper part of a one-wheeled vehicle body, and the fertilizer in the tank is delivered by a fertilizer delivery pump, and the fertilizer can be applied from a fertilization section having a fertilization nozzle and a rotating blade. be.

The above-mentioned known fertilization device has problems not only in separating the standing plants, but also in its overall structure, since it applies fertilizer by moving between the standing plants in a paddy field.

However, in the present invention, the distance between the rows 25 on both the left and right sides of the driving wheel 4 of the one-wheeled traveling vehicle body 1 having the engine 6 is
Alternatively, a left fertilizer tank 22 and a right fertilizer tank 23 are provided above the row spacing 25, respectively, and the traveling vehicle body 1 behind the left fertilizer tank 22 is provided with a left transmission case 26 having a left drive grounding wheel 36 provided at its lower part. A left fertilizing pump 27 is installed approximately vertically and is directly connected to the upper side wall of the left power transmission case 26 by the left drive grounding wheel 36, and a left fertilization nozzle 30 is installed at the rear of the lower part of the left power transmission case 26. A right power transmission case 26 having a right drive grounding wheel 36 at its lower part is installed in the traveling vehicle body 1 behind the right fertilizer tank 23 in a substantially vertical manner, and the right drive grounding wheel 36 is provided on the upper side wall of the right power transmission case 26. It is directly equipped with a right fertilizer pump 28 that is interlocked and connected by a ring 36, and a right fertilizer nozzle 33 is installed at the rear of the lower part of the left transmission case 26, and the left fertilizer tank 22, the left fertilizer pump 27, and the left driving ground wheel are connected to each other. 36, the left fertilizer nozzle 30, and the right fertilizer tank 2
3, the right fertilizer pump 28, and the right drive grounding wheel 3.
6 and the right fertilizing nozzle 33 are arranged linearly within the same row spacing 25 in a plan view, and the left power transmission case 26 and the right power transmission case 26 as well as the left fertilization nozzle 30 and the right fertilization nozzle 33 are shown in a side view. Since this is a deep layer fertilization device for paddy fields arranged in an overlapping arrangement, the left fertilizer tank 22, left fertilization pump 27, and left fertilization nozzle 30, and the right fertilizer tank 23, right fertilization pump 28, and right fertilization nozzle 33 are arranged between the same rows. 25, the fertilizer flows smoothly from the fertilizer tank to the fertilizer application nozzle.

The machine body can be moved forward using the left and right fertilizer tanks 22 and 23 as marks of the fertilization position, and the driving operation is easy.

The mounting structure of the fertilization pump is simple and compact by using the transmission case as the mounting member, and can be easily placed between rows without pushing down the crops. Since the fertilization pump and grounding ring are installed above and below a single power transmission casing, there is no fear that the relative position of the fertilizing pump and grounding ring will be distorted, and the interlocking relationship between the two can be maintained in good condition over many years. , stabilization of fertilization performance can be achieved.

Since the left power transmission case 26 and the right power transmission case 26 and the left fertilization nozzle 30 and right fertilization nozzle 33 are arranged in an overlapping arrangement in a side view, the longitudinal length of the machine body can be configured to be as short as possible. You can make small turns in both the left and right directions on adjacent headlands.

This effect is achieved.
