ABSTRACT:
A harvester for plants such as Irish moss is disclosed. The harvester may be towed along the sea bed by a surface vessel and provides for the continuous pumping of harvested plants to the vessel by way of an enclosed conduit. The harvester includes a plurality of axially spaced harvest rollers rotatably mounted in a frame. A plurality of guide rollers are pivotally mounted relative to the harvest rollers in advance thereof with each guide roller being longitudinally aligned with a corresponding space between adjacent harvest rollers. A continuous mesh-like harvest belt extends around the guide and harvest rollers with the lengthwise members thereof being entrained around the guide rollers and positioned in the spaces defined between the harvest rollers. The transverse members of the belt are flexible and extend between the endless members so as to be positioned, in the lower run thereof on the sea bed, and so as to engage and conform to the contour of the harvest rollers. Plants are trapped between the transverse belt members and the harvest rollers so as to be pulled from the sea bed for subsequent deposit in a collection trough from which they are pumped to the surface vessel. The harvester is simple and economic to produce and use and is efficient in collecting a wide swath of plants from the sea bed.
