Abstract
Claims
1. A device for mixing and shaking cell culture, comprising a base (1), a cylinder (2) is fixedly installed on the upper side of the base (1), a motor is installed in the base (1), a vertically upward extending rotating shaft (3) is installed on the output end of the motor, characterized in that: The upper end of the rotating shaft (3) is equipped with a planetary gear system, which includes a central gear (10), multiple planetary gears (11), a planet carrier (7), and an internal gear ring (8). The planetary gears (11) are respectively installed on the outer side of the planet carrier (7). The central gear (10) is fixedly installed on the upper end of the rotating shaft (3). The internal gear ring (8) is fixedly installed on the upper end of the cylinder (2). The planetary gears (11) are distributed in the annular area between the central gear (10) and the internal gear ring (8) and mesh with them. Multiple rotatable tubes (12) are axially installed on the outer side of the planet carrier (7). The planetary gears (11) are fixedly installed on the upper part of the tubes (12) one by one. The rotating shaft (3) passes through the middle of the planet carrier (7) and is clearance-fitted with it. The lower part of the rotating shaft (3) is provided with an annular flange (4), and a spring (5) is connected to the upper side of the flange (4). The upper end of the spring (5) is connected to an annular support plate (6). The support plate (6) is sleeved on the rotating shaft (3) and can slide along the axial direction of the rotating shaft (3). Multiple bullseye bearings a are fixedly installed on the upper side of the support plate (6) along the circumference. The bullseye bearings a are used to support the planetary carrier (7) from the bottom. The upper side of the planetary carrier (7) is provided with a radially extending protrusion (9). The central wheel (10) is installed with an axially downward extending round rod (13) at the eccentric position. The lower end of the round rod (13) is installed with a bullseye bearing b. The bullseye bearing b presses on the upper side of the planetary carrier (7).
2. The device for mixing a cell culture solution according to claim 1, wherein: The inner cavity of the tubing (12) is fitted with a foam sleeve, which is used to fix the test tube inserted therein.
3. The device for mixing a cell culture solution according to claim 1, wherein: The cross section of the protrusion (9) is a symmetrical arc surface with a high middle and low sides. There are two protrusions (9) located on the same radial straight line. There are two round rods (13) and they are symmetrical about the axis of the central wheel (10).
