[Problems to be solved by the device]

 It is possible to spray compost on the entire surface of the field with conventional spraying equipment such as compost, but when the crop is planted and grown, the sprayed compost falls on the work. However, the crops are damaged, and the compost cannot be applied as additional fertilizer. In recent years, due to the boom in healthy foods, vegetables and the like have been organically cultivated in order to obtain these healthy foods. In this organic cultivation, between vegetables and other rows planted in the field. As described above, compost such as chicken manure and cow manure is supplied as additional fertilizer. This work is currently performed manually, and is a labor-intensive work, and it is desired to perform it mechanically.However, since there is no simple mechanical device for performing this work, at present, for example, the above The fertilizer is used to transport fertilizer along the ridges while manually spreading the compost between crop rows.

Under such circumstances, the present invention develops a conventional agricultural stilt vehicle to mechanically and continuously transfer an object to be treated such as compost between rows of crops on a ridge. The aim is to provide an agricultural stilt-type transport and discharge work vehicle that can be applied in a striped manner.
