Description

Technical Field

[0001] The utility model relates to the technical field of biological stirring, in particular to a biological stirrer. Background Art

[0002] Biological mixers can be used and used in different environments. In the production and processing of medicines, mixers are needed to mix the medicines. Therefore, mixers can evenly mix the raw materials, control the reaction rate and temperature, and ensure product quality and safety.

[0003] For example, a constant temperature biological stirrer with application number 202222201945.2 has a specially designed semiconductor cooling chip and uses a temperature sensor to detect the temperature of the rotating shaft. Once the temperature of the rotating shaft rises above room temperature, the semiconductor cooling chip is activated to reduce the temperature of the rotating shaft, preventing the rotating shaft from transferring heat to the stirring rod, thereby improving the temperature stability of the stirring rod and avoiding uncertainties in the biological reaction. However, the device still has certain defects;

[0004] During the stirring process, the stirring rod is in a fixed position. Therefore, the stirring blades on the stirring rod rotate but are also fixed in position. This causes the stirring blades on the stirring rod to break easily when subjected to force, thereby affecting the service life of the stirring rod and the stirring blades.

[0005] So we proposed a biological mixer to solve the problems raised above. Utility Model Content

[0006] The purpose of the present utility model is to provide a biological agitator to solve the problem raised in the above background technology that the stirring rod of the existing biological agitators on the market is fixed in position during the process of force stirring. Therefore, the stirring blades on the stirring rod not only rotate but also have a fixed position, which causes the stirring blades on the stirring rod to easily break when subjected to force, thereby affecting the service life of the stirring rod and the stirring blades.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a biological agitator, comprising a mixing box body, a movable sleeve mounted on the outside of the mixing box body via a telescopic spring, a through slot being formed above the movable sleeve, a drive assembly being mounted above the mixing box body, connecting plates being mounted on opposite sides of the movable sleeve, and impact blocks being mounted on the lower ends of the connecting plates;

[0008] A magnetic drive assembly is installed inside the mixing box body, and the magnetic drive assembly is magnetically coupled. A stirring rod is installed on the right side of the magnetic drive assembly, and a stirring blade assembly is installed on the stirring rod. The blade angle of the stirring blade assembly is 30°. A base assembly is installed on the right side of the inner wall of the mixing box body, and a fixed rod sleeve is installed on the left side of the base assembly. A fixing assembly is installed on the fixed rod sleeve. A limiting rod is installed on one end of the stirring rod relative to the fixed rod sleeve, and the diameter of the limiting rod is larger than the diameter of the stirring rod.

[0009] Preferably, two telescopic springs are provided, and the telescopic springs are located on the upper and lower sides of the mixing box body.

[0010] With the above structural design, the movable sleeve can move up and down under the action of the telescopic spring when subjected to force.

[0011] Preferably, the driving assembly includes a driving motor, a transmission shaft and a cam mechanism. The driving motor is installed above the mixing box body, and a transmission shaft is installed on the left side of the driving motor through the output shaft. The cam mechanism is installed on the transmission shaft, and the cam mechanism is fixedly connected to the transmission shaft.

[0012] By adopting the above structural design, the driving motor is started, and the driving motor drives the transmission shaft to rotate through the output shaft, and the transmission shaft drives the cam mechanism to rotate, so that the connecting plate can be intermittently squeezed, and the connecting plate drives the impact block to move toward the mixing box body, impacting the mixing box body, causing the mixing box body to vibrate, thereby improving the mixing efficiency of the organisms in the mixing box body. At the same time, the movable sleeve can be manually pulled down continuously, and the movement of the movable sleeve can drive the impact block to impact the mixing box body.

[0013] Preferably, the diameter of the transmission shaft is smaller than the diameter of the through groove, and the transmission shaft is connected to the upper part of the mixing box body through a bearing seat.

[0014] With the above structural design, when the movable sleeve moves up and down under force, the through groove on the movable sleeve will not collide with the transmission shaft to cause obstruction.

[0015] Preferably, the impact block is fixedly connected to the connecting plate, and the line segment of the impact block is designed to be a spherical structure.

[0016] By adopting the above structural design, when the impact block impacts the mixing box body under force, damage to the surface of the mixing box body can be reduced.

[0017] Preferably, the left end of the fixing rod sleeve is provided with a groove, and three grooves are provided.

[0018] With the above structural design, the groove design reduces the production cost of the fixed rod sleeve on the one hand, and on the other hand, the groove makes it easy to observe whether the limiting threaded rod and the rubber ball are installed in place, and it is also convenient to clean the fixed rod sleeve.

[0019] Preferably, there are three fixing components, and the fixing components include a limiting threaded rod and a rubber ball. The limiting threaded rod is installed on the fixing rod sleeve.

A rubber ball is installed on one end of the limiting threaded rod along the inside of the fixing rod sleeve. The rubber ball is located inside the fixing rod sleeve, and the inner wall diameter of the fixing rod sleeve is larger than the diameter of the limiting rod.

[0020] With the above-mentioned structural design, the limiting rod on the stirring rod is extended into the fixed rod sleeve, and then the limiting threaded rod is rotated. The limiting threaded rod drives the rubber ball to move toward the inside of the fixed rod sleeve. The rubber ball can limit and protect the limiting rod, so that the stirring rod has a 10% retractable space when subjected to force. At the same time, the blade angle on the stirring blade assembly is 30°, which has low shear, so that the stirring rod and the stirring blade assembly are not easy to break, thereby increasing the service life of the stirring rod and the stirring blade assembly. At the same time, it is convenient to disassemble the limiting rod and the fixed rod sleeve and clean the inside of the fixed rod sleeve.
