Shellfish harvester

Abstract

The invention discloses a shellfish harvester, comprising a frame and is characterized in that two travelling motors that drive travelling wheels to rotate are arranged symmetrically on the frame, a conveyer belt motor that drives a conveyer belt to move is also arranged on the frame, retaining plates are arranged on two sides of the conveyer belt respectively, push blades are arranged at the bottom ends of the retaining plates, a scraper motor is also arranged on the frame, the operating end of the scraper motor is connected to a driving scraper shaft rotationally supported on the frame, a driven scraper shaft is also arranged on the frame, the driving scraper shaft and the driven scraper shaft jointly support a scraper chain, a plurality of scrapers are distributed evenly on the scraper chain, a carrier plate is arranged at the front of the frame, and an arc guide plate is arranged at the tail end of the conveyer belt and is positioned in front of a collection box arranged at the tail of the frame.

Description

technical field [0001] The invention relates to a seafood harvesting device, in particular to a shellfish harvesting machine. Background technique [0002] When handling seafood such as shells and clams that are accustomed to living on the seabed, it is often necessary for staff to dive into the water for operation. This method is time-consuming and laborious, and the work efficiency is low. There are generally two types of harvesting devices for seafood fishing, the suction pump type and the grab type. [0003] The rotation speed of the pump body winch of the suction pump type harvesting device is high, and the capture efficiency for seafood such as shells or clams is relatively high, and the leakage rate is low. Large damage will seriously affect the economic benefits of farmers; in addition, aquatic plants such as aquatic plants growing on the seabed will suffer devastating damage after passing through the winch of the pump body, seriously affecting the ecological enviro...

[0002] When handling seafood such as shells and clams that are accustomed to living on the seabed, it is often necessary for staff to dive into the water for operation. This method is time-consuming and laborious, and the work efficiency is low. There are generally two types of harvesting devices for seafood fishing: suction pump type and grab type.

[0003] The rotation speed of the pump body winch of the suction pump type harvesting device is high, and the capture efficiency for seafood such as shells or clams is relatively high, and the leakage rate is low. Large damage will seriously affect the economic benefits of farmers; in addition, aquatic plants such as aquatic plants growing on the seabed will suffer devastating damage after passing through the winch of the pump body, seriously affecting the ecological environment of the local sea area

[0004] The grab-type harvesting device uses a bucket to scoop up all the animals and plants such as soil, seafood (shells, clams, etc.) and aquatic plants into the collection net. Although the damage to the seafood itself is relatively small, its movement is slow , the work efficiency is low, and it will also cause a certain degree of damage to the ecological environment of Haiti
