Multifunctional molecular biology experiment specimen grinding device

Abstract

The invention discloses a multifunctional molecular biology experiment specimen grinding device, and relates to the field of grinding devices. The multifunctional molecular biology experiment specimengrinding device comprises an enclosure, wherein the side surface of the enclosure is equipped with a fan and is equipped with an air inlet tube in a penetrating mode; the air inlet tube is connectedto the fan; a grinding mechanism is arranged inside the enclosure; the grinding mechanism comprises a hemi-spherical grinding block; a circular table shaped connecting block is fixedly arranged on thetop of the hemi-spherical grinding block; the top of the circular table shaped connecting block is fixedly equipped with an upper rotary rod; the bottom of the hemi-spherical grinding block is equipped with a grinding base; a hemi-spherical grinding slot is formed in the top of the grinding base; grinding teeth are arranged at each of the outer side of the hemi-spherical grinding block and the inner side of the hemi-spherical grinding slot; a groove is formed in the bottom of the hemi-spherical grinding block; a blocking cover plate is fixedly arranged on the bottom of the groove; and the blocking cover plate is fixedly connected to the inner wall of the hemi-spherical grinding slot. In practical use, material recycling is not required, so that operation steps are effectively reduced, grinding efficiency is improved, and the practical use effect is better.

Description

technical field [0001] The invention relates to the technical field of grinding devices, more specifically, the invention relates to a multifunctional molecular biology experiment specimen grinding device. Background technique [0002] Grinding uses the abrasive particles coated or pressed on the grinding tool to finish the processing surface through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. Surface shapes include plane, inner and outer cylindrical and conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other profiles. The machining accuracy can reach IT5-01, and the surface roughness can reach Ra0.63-0.01 microns. [0003] The invention patent of patent application publication number CN 108787078 A discloses a multifunctional molecular biology experiment specimen grinding device, which includes a lower side box body, the lower ...

AI Technical Summary

Problems solved by technology

[0004] However, in actual use, there are still some shortcomings, such as the grinding process is still not fine enough, after the actual grinding, there are still parts that are not sufficiently ground, so it is necessary to recycle the part that is not fully ground and perform secondary grinding, thus increasing the cost. Operating steps, reducing grinding efficiency
