The utility model discloses a gravity type seed fine selection grading machinery, including total frame body,
electric control box, conveyer belt, hopper, elevating type spacing baffle, even material cross board, dust baffle, vibrating sorting
machine, total frame body left side positioning installation has conveyer belt, the hopper is positioned and installed on conveyer belt upper end position, the elevating type spacing baffle is in -situ installation in hopper front end box body sliding slot, and the even material cross board is positioned and welded in the elevating type spacing baffle board body bottom position, and the dust baffle is positioned and installed in the
tail end of conveyer belt and vibrating sorting
machine interface position, a gravity type seed fine selection grading machinery, seed motion forms the motion cavity convenient sliding movement to the elevating type spacing baffle drainage triangular ruler guide, and seed sliding through the triangular material tooth piece realizes even distribution and avoids the accumulation phenomenon to occur, and vibrating sorting
machine will seed vibration spread even material cross board's arrangement pressure roller and cooperate vertical arrangement shunt pole and make seed
carding flat, and the water
sponge and multilayer dust filter core of dust baffle do dust adsorption.
