However, in a flooded paddy field, it is not easy to replenish the lacked rice husks, so that necessary rice husk bags are loaded on the culvert laying machine from one end to the other end of the paddy field. The rice husk bags fell into the paddy fields during the laying work and got wet, and a lot of manpower was required to transfer them to the culvert laying machine. In addition, in order to supply rice husks to the drain layer part, besides the driver, the culvert laying machine has an operator who opens the rice husk bags and puts it into the hopper, and the husk loaded on the culvert laying machine for the worker. It was necessary for another worker to hand the bags one after another. As a result, it has become difficult to gather human resources in rural areas where depopulation is advancing, and soil improvement works could not be implemented as expected. Therefore, development of a rice husk supply device capable of successively supplying rice husks to a hopper by an operation of a driver alone has been awaited. In particular, in a conventional blower-type transfer device, rice hulls have a special feature that the transfer conditions are drastically changed between a dry state and a wet state, and it is necessary to be able to change the setting of the transfer conditions between the dry state and the wet state. It was difficult to make rice husk supply equipment.
