Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a special crane for automatic extraction and transportation of aquatic biomass. Background Art

[0002] With the development of modern society, more and more people begin to pay attention to health and wellness, and the demand for various vitamins and biological extracts such as DHA and algae oil is increasing. Correspondingly, aquatic biomass breeding plants that can extract various biotins have gradually become an emerging industry.

[0003] In the process of aquatic biomass cultivation, not only do we need to regularly extract and lift certain aquatic plants (such as waterweed, duckweed, etc.) to prevent their excessive growth from affecting water quality or occupying too much aquaculture space, but we also need to extract and lift specific aquatic biomass (such as shellfish cultivation). However, there are still the following deficiencies in the current extraction and lifting of aquatic biomass:

[0004] 1. Due to economic constraints, most aquatic biomass farms use boats driven by humans to salvage and extract aquatic biomass. This method is not only time-consuming and labor-intensive, with low extraction and lifting efficiency, but also poses certain safety hazards;

[0005] 2. Some existing aquatic biomass farms also use some mechanical lifting devices (such as winch lifting systems and trawl lifting systems) for extraction and lifting operations. However, these mechanical lifting devices have a low degree of automation and still require manual control and operation;

[0006] Therefore, there is an urgent need for a special crane for automatic extraction and transportation of aquatic biomass that can overcome the above-mentioned disadvantages. Utility Model Content

[0011] Furthermore, the taking bucket is a regular quadrilateral structure, and the maximum spacing between the slide grooves on both sides of the side baffle is adapted to the width of the opening at the lower end of the taking bucket.

[0012] Furthermore, the driving mechanism includes end plates and waterproof telescopic cylinders. End plates are provided at both ends of the upper edge of the movable plate.
