(effect) Next, we will discuss the effect.

When the engine 6 is started, the walking steering handle 7 is supported, and the robot moves forward, the left transmission case 25 of the left fertilization section 17
The left ground drive wheel 30 provided at the lower end rotates while being in contact with the field, and the rotation of the left ground drive wheel 30 is transmitted through the drive shaft 29 → drive gear 33 → chain 36 → passive gear 35 → passive shaft 34. and the passive shaft 34
Since the left fertilization pump 27 and the right fertilization pump 28 are operated simultaneously, the fertilizer in the fertilizer tank 22 is passed through the left and right fertilization pipes 40 by the left fertilization pump 27 and the right fertilization pump 28 to the left and right fertilization nozzles 4.
1, and fertilizes the grooves formed deep into the soil by the rotary blade 51 and the groove cutting blade 50. Further, the rotation of the right ground driving wheel 32 provided at the lower end of the right power transmission case 26 of the right fertilization section 18 is also caused by the rotation of the drive shaft 31 → drive gear 37 → chain 39 → passive gear 38 → passive shaft 34.
Similarly, the passive shaft 34 simultaneously operates the left fertilizer pump 27 and the right fertilizer pump 28, so that the fertilizer in the fertilizer tank 22 is transferred to the left fertilizer pump 2.
7 and the right fertilization pump 28, the fertilizer is sent to the left and right fertilization nozzles 41 through the left and right fertilization pipes 40,
Fertilization is applied to grooves formed deep in the soil by the rotary blade 51 and the groove cutting blade 50.

That is, both ends of the passive shaft 34 are connected to the left fertilizer pump 27 and the right fertilizer pump 28, and the passive shaft 34 is connected to the left fertilizer pump 27 and the right fertilizer pump 28.
The structure is such that the left side fertilization pump 27 and the right side fertilization pump 28 are driven respectively by the rotation of 4, and the left side fertilization pump 27 and the right side fertilization pump 28 are driven in conjunction with each other, so that the left side ground driving wheel 30 and the right side ground driving wheel 32 are driven in conjunction with each other. When either one rotates, the passive shaft 34 rotates, driving the left fertilization pump 27 and the right fertilization pump 28. Therefore, the left side fertilization pump 27 and the right side fertilization pump 28 are always driven, and no fertilization group is generated.

(Effect) As described above, a left side fertilization pump and a right side fertilization pump connected to a fertilizer tank are provided between the left and right rows of the single drive wheel, respectively, and a left side fertilization pump and a right side fertilization pump are installed between the rows. Fertilizer application devices are known in which a left ground contact drive wheel and a right ground contact drive wheel are separately driven. However, the above-mentioned known device has a problem in that when one of the grounding wheels does not rotate due to an inclination of the machine body, the fertilization pump on that side does not operate. this is,
This was a very troubling problem as it was the cause of the problem for the fertilizer application team, but it was usually difficult to detect.

However, in the present invention, a left fertilizer pump 27 is connected to the fertilizer tank 22 between the rows 24 on both the left and right sides of the single-wheel drive wheel 4 driven by the engine 6.
and the right side fertilization pump 28 and the left side ground drive wheel 30
and a right side ground driving wheel 31 are provided, and the left side fertilization pump 27 and the left side ground drive wheel 30 are connected by a chain 36 to the front right side fertilization pump 28 and the right side ground drive wheel 32 by a chain 39, and the left side fertilization Pump 27 and right side fertilization pump 2
8 is a deep fertilization device for paddy fields that is connected via a passive horizontal shaft 34 so that it can be rotated only by the rotation of either the left or right ground contact wheel.
When either the left ground driving wheel 30 or the right ground driving wheel 32 rotates, the passive shaft 34 rotates and drives the left fertilization pump 27 and the right fertilization pump 28. The fertilization pump 28 is driven and has the effect that no fertilization teams are generated.
