A thermoplastic resin composition of the present invention comprises: a polycarbonate resin; a large-particle diameter rubber polymer having an average particle size of about 500-3,000 nm; an aromatic vinyl copolymer resin; a core-shell graft copolymer; and a phosphorus flame retardant, wherein the core-shell graft copolymer comprises a shell formed by graft polymerization of epoxy group-containing acrylate monomers to a silicon-based rubber polymer core having an average particle size of about 100-300 nm. The thermoplastic resin composition is excellent in hydrolysis resistance, impact resistance, flame retardancy, heat resistance, fluidity, appearance characteristics, etc.

Thermoplastic resin composition and article produced therefrom

The present invention relates to an automatic bee separation device, and more specifically, to an automatic bee separation device capable of automatically withdrawing a beehive accommodated in a bee box, performing bee separation at the same time, and when the bee separation is completed, inputting the beehive to the bee box. In the automatic bee separation device according to the present invention, since beehive withdrawal work and bee separation work are performed at the same time without requiring a worker to directly and manually withdraw the beehive from the bee box when the bee separation work or honey extraction work is performed after the bee separation work, a speed and efficiency of the work can be maximized in addition to an effect of reducing a labor cost. Therefore, as productivity increases, an effect of increasing income can be generated.
