The invention discloses a novel chromatography device capable of automatically feeding liquid. The novel chromatography device comprises a chromatographic column, a spherical nozzle container, a speed-adjustable peristaltic pump and a pressure pump, wherein the spherical nozzle container comprises a spherical main body and a spherical funnel pipe which is provided with a closed lower end and is fixedly connected with the peripheral main body; the spherical funnel pipe comprises an elliptical ball part and a barrel-shaped pipe for communicating the upper end of the elliptical ball part with thespherical main body; the lower end of the elliptical ball part is closed; multiple liquid flowing holes of same sizes are formed in the ball wall of the elliptical ball part; the top of the sphericalmain body is connected with a Y-shaped three-way joint; the lower end of the barrel-shaped pipe is inserted into the chromatographic column. An eluent is added into the chromatographic column throughthe liquid flowing holes so as to be prevented from damaging the surface of silica gel; the pressure pump solves the problem of low elution rate; the speed-adjustable peristaltic pump can precisely add the eluent into the spherical nozzle container instead of manually frequently adding the eluent into the chromatographic column, so that the labor is saved.
