A quantitative device for taking granular drugs is provided with a base cover (1) connected with an opening of a package bottle of the granular drugs, a quantitative container (2), a partition plate (3) capable of opening and closing a channel (1b) and a sealing cover (4). The cover face of the base cover (1) is provided with a boss (1a), wherein the channel (1b) communicated with a containing cavity of the package bottle is formed inside the boss. The lower end of the quantitative container (2) is combined with an upper opening end wall of the channel (1b) in the base cover, a quantitative containing cavity (2a) of the quantitative container is communicated with the channel (1b), and the upper end of the quantitative container is provided with a detachable seal cover (2b). The partition plate is located above the cover face of the base cover (1). The sealing cover (4) is connected with the base cover (1). The quantitative device has the comprehensive functions of quantification, isolation after the quantification is conducted and sealing. Through simple operation, corresponding quantification of the taking dose in each time can be achieved, the drugs can be taken conveniently after quantification is conducted, and the hand is prevented from making contact with the granular drugs in the quantitative operation process.
