Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fertilizer transplanter in which fertilizers from left and right fertilizer tanks are guided to a fertilizer nozzle through indicators and fertilized on each planting strip.
[0002]
[Prior art]
Generally, fertilizer transplanters equipped with fertilizer application equipment are known, but such fertilizer transplanters are equipped with fertilizer tanks on the left and right sides of the machine, and the fertilizer from these fertilizer tanks is pumped with a fertilizer pump. Then, it guides to the fertilizer nozzle provided on each planting section of the planting section through the indicator, the fertilizer from the left fertilizer tank is in the left half of the planting section, the fertilizer from the right fertilizer tank is the planting section Fertilizer is applied to the right half.
[0003]
And, for example, in the case of ten-row planting, when the aircraft comes to the shore and turns around, as shown in FIG. In B, the planting strip C (four strips indicated by a dotted line in the drawing) that overlaps in the next final process A is stopped. At this time, as shown in FIG. 6 (a), the fertilizer operation is stopped by operating the lever E of the indicator D corresponding to the planting strip to be fastened, and the fertilizer to the planted strip that has been fastened is transferred to the fertilizer tank by the return pipe. To reflux.
[0004]
However, in the conventional fertilizer transplanter, the return pipe from the left indicator is connected to the left fertilizer tank, and the return pipe from the right indicator is connected to the right fertilizer tank. For this reason, as shown in FIG. 6 (b), when the four strips of the right indicator R are stopped, the four fertilizers are returned to the right tank R by the four return pipes F. The fertilizer stored in the tank R decreases only for one fertilized fertilizer, while the left tank L, which does not stop, reduces the fertilizer for the five fertilized fertilizers. There will be a gap in the amount of fertilizer remaining in the tank. For this reason, when either one of the tanks becomes empty, there is an inconvenience that the fertilizer must be replenished even during the work.
[0005]
In the case of low-viscosity fertilizers, it is suggested to connect the left and right tanks with pipes etc. to make the remaining amount of fertilizer substantially uniform, but for high-viscosity paste fertilizers, pipes etc. By simply connecting the tanks, it is not possible to expect a sufficient effect to make the remaining amount of fertilizer uniform.
[0006]
