Description

Technical Field

[0001] This utility model belongs to the field of fishery technology, specifically relating to a beach shellfish harvesting shovel. Background Technology

[0002] Harvesting shellfish (such as clams and razor clams) on the beach is a common recreational and productive activity. Currently, the tools used for harvesting shellfish typically include rakes (such as spiked rakes), negative pressure suction devices, or specialized large-scale harvesting equipment. When using rakes, harvesters need to loosen the sand by swinging the rake and then pick out the shellfish. While this method uses simple tools, the limited length of the rake's teeth means it can only work on the surface of the sand, rendering it ineffective at harvesting shellfish buried deeper, resulting in low harvesting efficiency and a high risk of missing some. Furthermore, repeatedly swinging the rake requires a significant amount of physical exertion, making it very strenuous for the harvester. Negative pressure suction devices can draw out sand and shellfish together using the suction force generated by pipes. However, in practical applications, the devices lack a stable point of force application on soft sandy beaches, making it difficult for operators to apply sufficient pressure to penetrate deep into the sand. Furthermore, their efficiency is affected by the beach's moisture content and sand composition, performing poorly on dry or dense sand. Additionally, the suction force is difficult to match with the size of the shellfish; too little suction fails to extract shellfish, while too much suction may damage small shellfish or cause blockages due to excessive sand and gravel. While specialized large-scale collection devices are highly efficient, they are primarily used in commercial, large-scale shellfish farms. Their large size, complex structure, and high price make them unsuitable for individual hobbyists, families, or small-scale fishermen in complex terrains such as intertidal zones and shallow waters, lacking flexibility and versatility.
