When the engine 5 is started and the vehicle moves forward, the rear end of the traveling vehicle body 1 is supported by the sled body 32, and the grounding drive wheels 29 rotate in contact with the field, and the rotation rotates the fertilization pump 25 via the gear box 24. let The fertilizer pump 25 sucks the paste-like fertilizer in the fertilizer tank 16 and injects it deep into the soil through the fertilizer nozzle 27.

Therefore, the fertilizer tank 16 and the conduction case 2
3 are both located between adjacent rows 18, 18 where the driving wheels 3 are located, and the upper part of the rear end of the fertilizer tank 16 is formed into an inclined surface 20 that becomes lower toward the rear. A remaining amount gauge 21 that indicates the remaining amount of fertilizer in the fertilizer tank 16 is provided on the slope 20, and on the upper rear side of the conduction casing 23 from the ground driving wheel 28 to the fertilization pump 25. Since the indicator 30 is provided, the remaining fuel gauge 21 and the indicator are both disposed in the same space between the rows 18, 18 in a vertical positional relationship.
and Indicator 30 can be viewed at the same time, so you won't miss any interruptions in fertilizer supply.

(Effect) The known fertilizer remaining amount meter and indicator are as follows:
It was installed in a different location, some distance away, so I couldn't see it at the same time. As a result, we sometimes made mistakes when we realized that the fertilizer tank was empty or the fertilizer pump was not discharging the fertilizer.

However, the present invention includes a traveling vehicle body 1 provided with a single-wheel drive wheel 3, a fertilizer tank 16 provided with a fertilizer remaining amount gauge 21 on the rear side, a ground-contact drive wheel 28, and a fertilization system rotated by the drive wheel 28. a pump 25 and a transmission casing 23 extending from the drive wheel 28 to the pump 25;
and an indicator 30 for confirming fertilizer discharge provided on the rear side of the conduction case 23, wherein the fertilizer tank 16 and the conduction case 23 are arranged within the same row space on both sides of the drive wheel 3, respectively. death,
and the fertilizer remaining amount meter 21 and the indicator 3
0 means that when viewed from the rear side, the fertilizer remaining amount gauge 21 is in the upper front direction and the indicator 3 is in the upper front direction within the same row spacing.
Since this is a deep layer fertilization device for paddy fields, which is characterized in that they are arranged in a vertical relationship with 0 pointing downward at the rear, the indicator 30 and the remaining amount meter 21 are arranged in a vertical relationship within the same row interval. This is effective because it can be checked at the same time, and there is less risk of overlooking interruptions in fertilizer supply.

Since the fertilizer remaining amount gauge 21 and the indicator 30 are arranged in the same row space on both sides of the driving wheels 3, they are located close to the driver walking along the wheel track, so that the remaining amount of fertilizer can be seen on both the left and right sides. The total 21 and the indicator 30 can be easily checked and have good visibility, and good driving operability can be maintained.

In particular, since the indicator 30, which requires frequent confirmation, is disposed at the lower rear on the side closer to the driver, it can be easily checked while driving while walking.
Then, when checking the indicator 30,
The remaining fertilizer level meter 21 is located in the front and upper field of view.
Since this exists, it is inevitable that the fertilizer remaining amount meter 21 can be checked, and both can be easily checked visually.
