Abstract

PURPOSE:To surely apply fertilizer deeply into field, by forcedly dropping fertilizer fed from a supply part into a manure channel deeply formed in field with compressed air. CONSTITUTION:A drive arm 16 is rotated with operation of a transplanter 6, a rocking arm 20 is oscillated through a rod 21 and each fixed amount of granular fertilizer in a tank 12 is fed by a fertilizer supply part 13. Since compressed air in an air tank 17 sent by an electrically-driven blower 16 is introduced to each guide member 15 by a pipe 18, the granular fertilizer is surely sent into a channel forming device 11 and surely fertilized in soil at the side of seedlings to be transplanted. Simultaneously, a rocking arm 25 is oscillated by fluctuation of the rocking arm 20 and each fixed amount of the granular fertilizer in a tank 12' is fed by a fertilizer supply part 13'. Since the compressed air is sent to each guide member 15' by a pipe 18', the granular fertilizer is surely sent to a channel forming device 11' with the compressed air and surely manured deeply in soil at the central positions between seedlings to be transplanted.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a deep fertilization device.

[Conventional technology and its issues]

Conventionally, it has been extremely difficult to apply fertilizers deep into the soil of paddy fields, and there have been no deep fertilization devices that have been put to practical use.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention uses a rotary body to forcefully flow down the fertilizer, which is delivered by a delivery unit into a fertilization groove formed in a field using pressure air, to apply fertilizer deep into the soil. This is a deep fertilization device with the following characteristics.

〔Effect of the invention〕

According to the present invention, the deep fertilization device is characterized in that the fertilizer fed by the feeder into the fertilization groove formed in the field by the rotating body is forced to flow out using pressure air to apply the fertilizer deep into the soil. Because it is.

Fertilizer can be applied accurately deep into the paddy soil.
