Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a grinding device for chemical experiments comprises a bottom plate 1, two sets of support rods 10 are fixedly installed at the top end of the bottom plate 1, a placing plate 15 is fixedly installed at the top end of each support rod 10, two sets of strip-shaped through holes with rectangular cross sections are vertically formed in the placing plate 15, a placing part 9 is arranged at each strip-shaped through hole in a sliding manner, each placing part 9 comprises two sets of lifting columns 14 with cross sections matched with the strip-shaped through holes, a mortar 12 is rotatably connected between the upper parts of the side walls, close to each other, of the lifting columns 14 through a rotating rod 13, two sets of support columns 6 are fixedly installed at two sides of the top end of the placing plate 15, a top plate 5 is fixedly installed at the top end of each support column 6, a push rod motor 4 with an output shaft vertically downward is fixedly installed at the bottom end of the top plate 5, the bottom end of the first motor 8 is fixedly provided with the grinding part 3.

Furthermore, the grinding part 3 comprises a grinding body 16, the bottom of the grinding body 16 is hemispherical, the outer side of the bottom of the grinding body is uniformly provided with protrusions 17, the mortar 12 is hemispherical and matched with the bottom of the grinding body 16, and the center of the sphere of the grinding body 16 is overlapped with the output shaft of the first motor 8 and the axis of the grinding part 3, so that the grinding part 3 can well grind the raw materials in the mortar 12.
