The invention discloses a prawns quality detecting and classifying device based on a machine vision technology. The prawns quality detecting and classifying device based on the machine vision technology include a laying-off system, an image acquisition system, a classifying mechanism, a conveyor belt, a computer system and a controller system. A camera is fixed at the top end of a lighting box which is fixed above the conveyor belt, and a white unsmooth coating is painted on inner walls of the lighting box. Light source is light-emitting diode (LED) soft strip type light source belts which are distributed on four inner walls of the lighting box. Light source illuminates upwards, and reflects to the surface of the prawn through the white coating of the inner walls. After processing the collected image in a real time, the computer obtains corresponding information of the quality characteristic of the prawns and classifies that, and then controls a spray valve through a controller. Passing through a corresponding spray valve, the prawns with a different quality classification are blown into a corresponding collecting groove, while the prawns not blown by the spray valve directly drop into the collecting groove arranged at the ends of the conveyor belt. The prawns quality detecting and classifying device based on the machine vision technology can detects and classifies the prawns with different quality classifications by quickly and accurately detecting the morphology and color characteristic of the prawns.

The invention provides a fast detector of Clenbuterol hydrochloride residues which belongs to fast detecting instrument technology. The installation of all the components of the fast detector takes an operation table as the basis. A communication socket is arranged at the center of the front upper part of the operation table. A detection system is inserted in the communication socket. Guide seats are arranged at the two ends of a diagonal of the detection system. Driving components are arranged at the front center of the operation table, directly below the communication socket and the detection system. A control system is arranged at the back center of the operation table, at the due back of the driving parts and is connected with the driving parts. A detection circuit is arranged at the middle-lower back part of the operation table. After all components are arranged on the operation table, the operation table is fixed at the outside opening of a shell with an outer cover covering above the circumference of the operation table, thereby forming a complete enclosed device with the shell. The invention provides a fast detector of Clenbuterol hydrochloride residues which can be used in laboratory situation and non-laboratory situation and has the advantages of small size, field and simple operations and high detection sensitivity of a 1ppb detection limit.

The invention discloses a dustless blackboard eraser which comprises a cleaning portion, a dust collection portion and a driving portion. The cleaning portion is made by a scouping pad, multiple uniformly-distributed protrusions are arranged on one face of the cleaning portion, the cleaning portion is used for cleaning the surface of a blackboard, the dust collection portion comprises a vacuum suction device and a suction pipe communicated with the vacuum suction device, one end of the suction pipe is fixed on a fixing plate, the suction pipe is a hose, the driving portion is fixed on the fixing plate and drives the cleaning portion to move, and the cleaning portion is detachably mounted on a driving shaft of the driving portion. The dustless blackboard eraser is simple in structure and convenient to use and has wide application space in actual life and production.

The embodiment of the invention provides a detecting device for detecting a loudspeaker component. The loudspeaker component comprises a bracket and a loudspeaker disposed on the bracket, and the detecting device comprises a rack, a positioning mold and a detecting component. The positioning mold is used for mounting the bracket, and the positioning mold is disposed on the rack; and the detectingcomponent comprises a moving part and a probe component, the moving part is movably connected to the rack and is disposed at a distance from the positioning mold; the probe component is connected to the moving part and is disposed toward the positioning mold, and the probe component is used for detecting the loudspeaker component. In the detecting device provided by the invention, the positioningmold is used for placing the loudspeaker component, when the moving part moves toward the direction of the positioning mold, the probe component connected to the moving part can be used for detectingwhether the loudspeaker component is correctly mounted, so that the detection process of the loudspeaker component is more intelligent, the detection result is more accurate, the quality of the loudspeaker component is ensured, and meanwhile the working efficiency is also improved.
