The application provides a feed screening device, relates to the technical field of feed screening, and comprises a box body, a feed inlet is arranged at the top of the box body, a distributing cone and a fine material hopper are sequentially arranged from top to bottom below the feed inlet in the box body, a discharge opening of the fine material hopper extends below the bottom of the box body, a coarse material falling channel is arranged between the fine material hopper and the box body, a coarse material outlet is arranged at the lower part of one side of the box body, a screening assembly is arranged between the distributing cone and the fine material hopper, the screening assembly screens the falling material from the distributing cone, and the fine material falls into the fine material hopper and the coarse material falls into the coarse material falling channel. The present application disperses the concentrated falling material through the distributing cone, so that the material is more evenly distributed on the screening assembly, the contact area and contact opportunity of the material and the screen are increased, and the screening efficiency is improved. Compared with the vibrating stirring screen in the prior art, the present application does not need to disperse the accumulated material through a stirring assembly, the supply of additional power is avoided, and the energy consumption and production cost are reduced.

This invention discloses a collaborative intelligent water quality monitoring method using a dual-platform approach combining a drone and a biomimetic fish. It includes the following steps: The drone subsystem transmits the location and extent information of the initially screened contaminated area, along with spectral data, back to an intelligent remote monitoring platform in real time; a biomimetic fish precision detection task is generated, and the coordinates of the initially screened contaminated area and a preset monitoring path are sent to the biomimetic fish subsystem; the biomimetic fish subsystem collects measured data from the initially screened contaminated area and transmits the collected data back to the intelligent remote monitoring platform; based on the spectral data from the drone and the measured data from the biomimetic fish, data fusion is performed using spatiotemporal registration to obtain the fused contamination concentration inside and outside the contaminated area; an early warning level is automatically triggered according to the water quality anomaly level, and the coordinates of the contaminated area are pushed to the operation and maintenance terminal, completing the early warning response closed loop. This invention not only enables rapid response to pollution events and improves source tracing efficiency but also shortens the monitoring cycle.
