(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a running vehicle body of a fertilizer application device. is mounted on a horizontal shaft 4. 5 is the running vehicle body 1
6 is a running control handle provided at the rear end of the vehicle body 1 and protrudes rearward; 7 is a fuel tank; 8 is a sprocket and chain for transmitting the rotation of the engine 5 to the transmission 9; It is a built-in transmission case.

Fertilization sections are provided on both left and right sides of the traveling vehicle body 1. The fertilization section has a left fertilization section 10 and a right fertilization section 11 fixed by a connecting rod 12, and has a generally approximate shape when viewed from the front. Position 1.

The fertilization parts 10 and 11 are separate from the vehicle body 1, and are detachably attached to the vehicle body 1 from above. That is, a pair of mounting rods 13 in the longitudinal direction projecting forward from the connecting rod 12 are provided on the connecting rod 12, and the front ends of the mounting rods 13 are attached to protrusions projecting laterally from the traveling vehicle body 1 from above. Engage and secure with the retaining pin. After the connecting rod 12 is placed on the traveling vehicle body 1, it is similarly fixed with a retaining pin.

The bases of the left and right support arms 14 are fixed to the front side of the mounting rod 13, and the tip sides of the support arms 14 are fixed to the mounting table 1.
The fertilizer tank 16 containing the paste-type fertilizer is attached to the mounting table 15.
6 is placed above a space 18 between standing culms 17 in the field and fixed to the placement table 15 by a band 19.

The upper ends of transmission housings 20 are fixed to the left and right sides of the connecting rod 12, respectively, and a gearbox 21 is provided on the outer surface of the upper part of the transmission housing 20.
A fertilization pump 22 is provided on the inner surface of the container. The fertilization pump 22 is located at the rear of the fertilizer tank 16, and is located between plants 18 of the erect grain culms 17 in the field.

23 is a grass burying device provided at the lower end of the transmission housing 20, 24 is a front grass burying blade, and 25 is a rear grass burying blade. provided in a substantially straight line,
Weeds, etc. that have been pressed downward by the front grass burying blade 24 are subsequently pressed downward and buried by the lower end of the rear grass burying blade 25, and weeds, etc. that have not been buried by the front grass burying blade 24 are also buried in the rear grass burying blade 24. The lower end of the blade 25 is buried in the soil.

26 is a fertilizing nozzle connected to the fertilizing pump 22 provided at the rear edge of the rear grass-embedded blade 25, and 27 is a sled body.

Thus, a left-right direction drive shaft 28 is attached to the lower part of the transmission case 20, and a lug-attached ground drive wheel 29 is fixed to the drive shaft 28. 30 is a lug plate of the ground driving wheel 29 with lugs.

As shown in FIG. 4, the lug-equipped ground driving wheel 29 is connected to a connecting rod 1 that connects the left and right transmission casings 20, 20.
A gear 32 fixed to a rotating shaft 31 provided in 2
A chain 34 is wound between the gear 33 fixed to the drive shaft 28, and the rotation of the lug-equipped ground drive wheel 29 is directed to the gear box 21 via the rotation shaft 31.
The structure is such that the fertilization pumps 22 on the left and right sides are driven by transmitting the information to the fertilization pumps 22.

The rotary shaft 31 is formed into an upper drive shaft 35 by protruding into the gear box 21 . A passive shaft 36 is provided below the upper drive shaft 35, and any two of a small gear 37, an intermediate gear 44, and a large gear 38 can be detachably attached to the upper drive shaft 35 and the passive shaft 36. A chain 39 is wound around the two types of gears attached. Said chain 3
9 meshes with a tension gear 40. The tension gear 40 is attached to the tip of a mounting plate 41, and the mounting plate 41 is rotatably attached to the gearbox 21 by a horizontal shaft 42. 43 is a screw for fixing the mounting plate 41.

That is, in this embodiment, the small gear 37 and the central gear 44
and two types of large gears 38, Small gear 37 and large gear 38 Small gear 37 and medium gear 44 Large gear 38 and small gear 37 Large gear 38 and medium gear 44 Medium gear 44 and small gear 37 Medium gear 44 The amount of fertilizer applied can be adjusted in 6 different combinations using the large gear 38.

Reference numeral 45 denotes a protrusion for mounting an unused gear among the gears 37, 38, and 44.

(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 27, and the transmission housing 20
The front grass burying blade 24 of the grass burying device 23 provided at the lower end of the groove is created, and the rear grass burying blade 25 advances along the trace.

Thus, the lug ground drive wheel 29 provided at the lower end of the transmission housing 20 rotates in contact with the ground, and this rotation is caused by the lower drive shaft 28→gear 33→chain 34→gear 32→rotating shaft 31. The rotation of the rotating shaft 31 is transmitted from the upper drive shaft 35 to the small gear 37 to the chain 39.
Transmitted from the large gear 38 to the passive shaft 36, the fertilization pump 22 is operated to suck the paste fertilizer in the fertilizer tank 16, and inject it deeply into the soil from the fertilization nozzle 26 at the rear edge of the rear grass burying blade 25. and fertilize.

In this case, the upper drive shaft 35 and the passive shaft 36 in the gear box 21 include a small gear 37 and a middle gear 4.
A chain 39 is loosely wound around the two types of gears, and a tension gear 40 is meshed with the chain 39. 41 to remove the tension gear 40 from the chain 39, the two types of gears can be removed.

The small gear 37, the middle gear 44, and the large gear 38 are
Since they are formed into gears with different numbers of teeth, the two types of gears are: small gear 37 and large gear 38 small gear 37 and medium gear 44 large gear 38 and small gear 37 large gear 38 and medium gear 44 By combining the intermediate gear 44 and the small gear 37, and the intermediate gear 44 and the large gear 38, the amount of fertilizer applied can be adjusted in six ways.

(Effect) Conventionally, on a traveling vehicle body with a single-wheel type traveling wheel,
It is known that a fertilizer tank, a fertilizer pump, a fertilizer nozzle, a ground driving wheel, etc. are attached, and the fertilizer pump is driven by the rotation of the ground driving wheel.

In the above-mentioned known method, it was not possible to adjust the amount of fertilizer applied.

However, in the present invention, the traveling vehicle body 1 includes a fertilizer tank 16, a fertilizer pump 22, a fertilizer nozzle 26,
Attach the ground drive wheels 29 and the like, and connect the fertilization pump 22
is configured to be driven by the ground-contact drive wheel 29, in which a drive shaft 35 and a passive shaft 36 are provided facing each other between the fertilization pump 22 and the ground-contact drive wheel 29, and the drive shaft 35 and the passive shaft The shaft 36 is provided with any two of a small gear 37, a medium gear 44, and a large gear 38 in a detachable and replaceable manner, and a chain 39 is wound around the attached gear. Since it has the structure of
Only the combination of the small gear 37, the intermediate gear 44, and the large gear 38 provides the effect of being able to be adjusted in six ways, and has the effect of being simple in structure and easy to implement.
