Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a tunnel multi-unit for covering lotus roots and the like cultivated in a muddy field with a multi-film. Conventionally, when cultivating a lotus root or the like in a muddy field, a tunnel mulch is laid to promote the growth after planting the root portion. In this tunnel mulch, the stanchions were erected manually at the same interval as the width of the planting part, covered with the multi-film, and the holding stanchions were erected from above to prevent the multi-film from peeling off. . [0003] However, conventionally, the work of laying the multi-film has been performed manually, which is troublesome, and since it is a muddy field, a large amount of labor is required only by walking. Since the work is performed while walking in the mud, a work machine that mechanically lays the multi-film has been desired. [0004] The present invention is configured as follows to solve such a problem. A crawler-type traveling device is located below the traveling body that is configured to straddle the tunnel supports that are erected on both sides of the crop planted in the muddy field, and the main frame can be raised and lowered via a parallel link at the rear of the traveling body. supported on, to the main frame, and a support portion which is provided to be pulled out mulch film,
