AI Technical Summary

Technical Problem

In the existing technology, the high-strength cement sample preparation device affects the molding effect when impurities are adsorbed on the surface of the extruded structure, and the surface of the molded sample is uneven, which reduces the success rate of preparation and its practicality.

Method used

The device employs a lifting box and a grinding box structure. A self-locking forward and reverse motor drives a worm gear system to rotate the extrusion plate to clean impurities. The grinding wheel then polishes the sample surface. Combined with the automated operation of the control panel, automatic cleaning and grinding are achieved.

Benefits of technology

It improved the success rate and practicality of high-strength cement sample preparation, ensured the cleanliness of the extrusion structure and the flatness of the sample surface, and improved the operating efficiency and molding quality of the device.

Abstract

The utility model discloses a high-strength cement sample preparation device which comprises a frame, a mounting plate is mounted in the frame, a plurality of groups of sample cylinders fixedly penetrate through the upper part of the mounting plate, lifting boxes are mounted above and below the mounting plate, a polishing box is mounted on one side of the frame, and a control panel is mounted on the other side of the frame. Multiple sets of mounting shafts penetrate through the opposite faces of the two sets of lifting boxes through bearings, extrusion plates are mounted at the ends, close to the mounting plate, of the multiple sets of mounting shafts on the same side, worm wheels fixedly sleeve the side walls of the ends, away from the mounting plate, of the multiple sets of mounting shafts on the same side, and worms are mounted in the two sets of lifting boxes through bearings; the side walls of the two sets of lifting boxes are each provided with a self-locking type forward and reverse rotation motor. The high-strength cement sample preparation device has the beneficial effects that the lifting box is adopted, impurities adsorbed on the surface of the extrusion structure can be automatically cleaned through the arranged lifting box, and the sample preparation success rate of the high-strength cement sample preparation device is improved.
