is provided so as to be located outside of the grass burying device 25. The ground driving wheel 39 has a structure in which its rotation is transmitted to the gear box 21 by a sprocket and a chain provided in the transmission case 20, and drives the left and right fertilizer pumps 22, respectively.

(effect) Next, we will discuss the effect.

When the engine 5 is started and the aircraft moves forward, the rear end of the aircraft is supported by the sled body 34, and the ground drive wheels 39
is rotated in contact with the ground, and the rotation rotates the fertilization pump 22 via the gearbox 21.

On the other hand, as the machine moves forward, a grass burying device 25 is provided on the mounting plate 23 at the lower end of the transmission case 20, and the grass burying device 25 has a front grass burying blade 26 and a rear grass burying blade 27. Since the rear grass-buried blades 27 are formed in a straight line in the front and back so that they are on the same trajectory, the rear grass-buried blades trace the grooves created by the front grass-buried blades 26 in the soil of the field. 27 moves forward. Then, the fertilizer pump 22 sucks the paste fertilizer in the fertilizer tank 16 and transfers it to the rear grass buried blade 2.
The fertilizer is applied by injecting it deep into the soil using the fertilizer application nozzle 32 at the trailing edge of No. 7.

In this case, the fertilizing nozzle 32 at the bottom of the transmission case 20
The sled body 34 collects weeds and the like floating on the ground as the aircraft travels, and the collected grass clumps gradually increase in amount and come to interfere with the rotation of the ground drive wheels 39, but the present invention In this case, since the grass burying device 25 is formed by providing the front grass burying blade 26 and the rear grass burying blade 27 so as to be positioned in a straight line in the front and back, floating weeds and the like first pass through the front grass burying blade 27. The weeds, etc. that were not buried by the front grass burying blade 26 are buried in the soil by the lower end of the rear grass burying blade 27 guided by the lower edge of the grass burying blade 26. Therefore, the fertilizing nozzle 32 and the sled body 34 collect weeds and the like floating on the ground, and prevent the grass from getting onto the drive shaft 38 of the ground-contact drive wheel 39 located between the transmission case 20 and the ground-contact drive wheel 39. The ground driving wheel 39 rotates accurately and prevents entanglement, and has the effect of accurately applying fertilizer.

(Effects) Conventionally, a fertilization unit including a fertilizer tank, a fertilization pump, a fertilization nozzle, a ground drive wheel, a grass burying device, etc. is attached to a running vehicle body, and the fertilization pump is configured to be driven by the ground drive wheel. A deep fertilization device for paddy fields in which the fertilization nozzle is provided on the rear side of the grass burying device is well known.

In the above-mentioned known deep fertilization device for paddy fields, the grass burying device had only one grass burying blade, so the action of the grass burying blade was not sufficient, and floating grass became entangled with the ground drive wheel, causing the ground drive wheel to rotate incorrectly. The problem was that it didn't.

However, in the present invention, the traveling vehicle body 1 includes a fertilizer tank 16, a fertilizer pump 22, a fertilizer nozzle 32,
Attachment of a fertilization unit having a ground driving wheel 39, a grass burying device 25, etc., in which the fertilizing pump 22 is configured to be driven by the ground driving wheel 39, the grass burying device 25 has a front grass burying blade 26 and a rear grass burying blade 26. Since the structure is two-tiered, the front and back of the buried grass blade 27, and the fertilization nozzle 32 is a deep fertilization device for paddy fields installed behind the rear grass buried blade 27, floating weeds and the like are first removed from the front grass. It is guided by the lower edge of the buried blade 26 and is pressed downward to be buried, and then the lower end of the rear grass buried blade 27 pushes the front grass buried blade 2
In step 6, unburied weeds and the like are buried in the soil. Therefore, the fertilizing nozzle 32 and the sled body 34
Collects weeds and the like floating on the ground, and removes them from the ground drive wheel 3 between the transmission case 20 and the ground drive wheel 39.
This prevents grass from wrapping around the drive shaft 38 of 9, allows the ground-contact drive wheel 39 to rotate accurately, and enables accurate fertilization.
