A kind of clam collecting machine

Abstract

The invention discloses a clam harvester which comprises a crawler wheel (1), wherein a distribution box (2) is arranged at the top of the crawler wheel (1); a feeding device (3) and a flushing water tank (4) are arranged at the top of the distribution box (2) respectively; the feeding device (3) and the flushing water tank (4) are in rotary connection fit; a lifting hopper (7) in rotary connection fit with the feeding device (3) is mounted at one end of the feeding device (3) opposite to the distribution box (2); and a telescopic cylinder (5) for controlling the digging depth of the lifting hopper (7) is arranged between the lifting hopper (7) and the feeding device (3). The clam harvester disclosed by the invention is simple in structure and convenient to use, and greatly improves the overall working efficiency and progress particularly for harvesting the clams different in the living depth in different seasons.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of marine biological farming machinery, and in particular to a clam harvester. Background technique [0002] Clams belong to the phylum Molluscs, Bivalvia, Euphyllobranches, Clamidae, and Clams. Its shell is slightly triangular, its belly is round, its shell is hard and thick, and the two shells are equal in size. It likes to live in the inner bay with fresh water and the fine sandy beach near the estuary. Its habitat depth varies with the water temperature and individual size. In winter, the burial depth of 2-3cm clams is 6-8cm, and the burial depth of 4-6cm large clams is about 6-10cm. In summer, when the water temperature is high, they basically inhabit the surface layer of tidal flats less than 1cm deep. Due to the above characteristics of meretrix meretrix, most of the current collection methods are still carried out manually, and the overall labor intensity is relatively high. A sk...

Its shell is slightly triangular, its belly is round, its shell is hard and thick, and the two shells are equal in size. It likes to live in the inner bay with fresh water and the fine sandy beach near the estuary. Its habitat depth varies with water temperature and individual size. In winter, the burial depth of 2-3cm clams is 6-8cm, and the burial depth of 4-6cm large clams is about 6-10cm. In summer, when the water temperature is high, they basically inhabit the surface layer of tidal flats less than 1cm deep. Due to the above characteristics of meretrix meretrix, most of the current collection methods are carried out manually, and the overall labor intensity is relatively high. A skilled worker can only collect about 80-140 catties a day at most.
