Description

Technical Field

[0001] The utility model belongs to the technical field of boll pressing, and particularly relates to an easily replaceable boll pressing device for a multi-head grinding and pulverizing machine. Background Art

[0002] For a traditional screw-pressing type assay sample preparation pulverizer, after tightening the compression nut on the pressing rod, the boll body is pressed by the pressing claw to carry out the pulverizing and sample preparation work. In the current design, the connection between the pressing rod and the vibration panel relies on external threads. Although this design is relatively simple during the initial installation, after long-term use, when the pressing rod needs to be replaced, the existing threaded connection method makes the operation process complex and time-consuming. When the pressing rod needs to be disassembled, the entire vibration panel needs to be removed first to take out the pressing rod, which not only increases the complexity of the operation but also may cause damage or deformation of the vibration panel. Content of the Utility Model
