Description

Technical Field

[0001] The utility model relates to the technical field of black soldier fly seedling screening, in particular to a black soldier fly seedling screening device. Background Art

[0002] The black soldier fly, scientifically known as Echinops scutellaria, belongs to the genus Echinops in the family Schizophora in the order Diptera. Its larval stage is a saprophagous feeder and is currently widely used in the treatment of organic waste, including food waste and livestock manure. The larvae can convert nutrients from organic waste into their own substances, which can then be used as organic fertilizer. Black soldier fly larvae are highly nutritious, containing approximately 42% to 44% crude protein, 31% to 35% crude fat, 4.8% to 5.1% calcium, 0.60% to 0.63% phosphorus, and 11% to 15% ash. They can be used directly in the farming of poultry, frogs, fish, shrimp, and crabs, or processed into dried insects for use as feed.

[0003] Chinese patent CN220343291U discloses a seedling screening device for aquatic product farming, including a protective bottom plate, threaded rods are horizontally installed at the center positions of the front and rear ends of the top of the protective bottom plate, sliding blocks are sleeved on one side of the outer surface of the threaded rods, rotating blocks are longitudinally installed at the top and rear ends of the sliding blocks, electric telescopic rods are longitudinally installed at the front and rear ends and the center position of the bottom of the rotating blocks, and a cleaning scraper is vertically added to the bottom of the electric telescopic rods, and object movement detectors are evenly installed on the inner sides of the protective bottom plate and the crawling inclined plate.

[0004] The above patent detects through an object movement detector that after the turtle seedlings stop crawling for a long time, the threaded rod drives the connected rotating block to move through the sliding block, and the rotating block and other structures on the rotating seat are rotated to adjust the angle. In this way, the turtle seedlings can be cleaned in time when they stop moving. However, in actual use, it is impossible to perform multi-stage screening according to the specifications of the black soldier fly seedlings, and it is impossible to clear the blockage of the screen cylinder during the screening process. Therefore, it is necessary to propose a new screening device for black soldier fly seedlings. Utility Model Content
