Diamond selection machine

Abstract

The invention discloses a diamond type selection machine and relates to the technical field of diamond type selection machine manufacture. The diamond type selection machine comprises a platen and a machine frame, wherein the machine frame comprises two upper joints, one upper joint is hinged to the platen. Two pairs of supporting rods are arranged on the two upper joints, one pair of supporting rods on each upper joint is respectively connected with one pair of supporting rods on the other upper joint through four lower joints. A sleeve and an ejection rod inserted into the sleeve and extending out of the upper end of the sleeve are arranged on one upper joint, and the ejection rod is hinged to the platen through a hinge shaft and is connected with the upper joint through four connecting-rod lifting devices. The platen is hinged to one supporting rod of the other upper joint through a hinge shaft and a rocker bar. A height adjusting device is arranged on the hinge shaft. Compared with the prior art, the diamond type selection machine is wide in adjustment range and can widen the range of diamond mono-crystalline sorted by an existing diamond type selection machine.

Description

technical field [0001] The invention relates to the technical field of diamond type selection machine manufacturing, in particular to a frame for the diamond type selection machine. Background technique [0002] At present, the selection machine is one of the indispensable equipment in the cubic boron nitride or artificial diamond industry; there is a diamond selection machine, which includes a fixed frame, which is equipped with A platform, at least two of the three support points are movable support points; a sorting disc is installed on the platform through a vibrator. This kind of diamond selection machine has the following problems in use: because the selection of diamond is by adjusting the angle and vibration frequency of the slant of the sorting sieve, and using the friction between the diamond and the surface of the sieving sieve to separate the diamond according to the crystal form The degree of integrity is separated to achieve the purpose of sorting, and the adj...

AI Technical Summary

Problems solved by technology

This kind of diamond selection machine has the following problems in use: because the selection of diamond is by adjusting the angle and vibration frequency of the slant of the sorting sieve, and using the friction between the diamond and the surface of the sieving sieve to separate the diamond according to the crystal form The degree of integrity is separated to achieve the purpose of sorting, and the adjustment of the height and rotation angle of the sorting screen is realized by adjusting the movable support point; while the height and angle adjustment range of the existing frame for the movable support point Therefore, the existing selection machine can only sort diamond single crystals from 30 mesh to 270 mesh
