Description

TECHNICAL FIELD The present invention relates to a seedling box scooping and transporting device capable of scooping up seedling boxes in a planted state prepared in an agricultural house and transporting them to a predetermined position.

Over the past few years, efforts have been made to reduce the cost of rice cultivation with the invention of rice transplanters. The supply required a great deal of labor and expense, and there was a demand for a reduction in these operations.
Conventionally, as a transport vehicle for nursery boxes, there has been known a wheelbarrow provided with one or two wheels under the bed provided with left and right side plates, a handle provided at the rear of the bed, and a handle lever for operating the stopper body on the handle. (See Patent Document 1).

In this known technique, after moving to an agricultural house in which seedling boxes are arranged in advance, the handle is lifted to ground the front end of the wheelbarrow, and the handle lever is operated to retract the stopper body from the side plate so that the handle is removed. If you move forward while holding the lever, the seedling box will be transferred to the loading platform while being guided by the left and right side plates. When a predetermined number of seedling boxes are loaded in this manner and the handle lever is released, the stopper body projects from the side plate, thereby fixing the seedling boxes on the carrier and preventing them from slipping down. Then, the seedling box is carried out from the agricultural house in the same manner as the conventional unicycle while the handle is lowered and the loading platform is kept substantially horizontal.
