Grinding device for biological experiment

Abstract

The invention provides a grinding device for a biological experiment, and relates to the field of biological experiments. The grinding device for the biological experiment comprises a bottom ring and a top frame, wherein the top frame is located above the bottom ring, the bottom ring is fixedly connected with the top frame through two fixing plates, a moving ring is arranged between the top frame and the bottom ring, the moving ring is located between the two fixing plates, the upper surface of the top frame is fixedly connected with a power box, vertical shafts are rotationally arranged at the four ends of the upper surface of the top frame in a penetrating mode, the upper ends of the four vertical shafts are in transmission with the four upper output ends of the power box through conveying belts correspondingly, and the lower output end of the power box rotationally penetrates through the upper surface of the top frame. According to the grinding device for the biological experiment, a grinding hopper, a supporting spring, the moving ring and an elastic plate are arranged, thus, the effect that mixed bone meal is vibrated out of the grinding hopper when the grinding hopper vibrates is achieved, and the problems that the powder grinding efficiency is reduced due to the fact that articles which are ground into powder cannot be separated from the bone meal mixture in time, and the articles which are ground into the powder are repeatedly ground are solved.

Description

technical field [0001] The invention relates to the field of biological experiments, in particular to a grinding device for biological experiments. Background technique [0002] Biological experiments refer to the process of purposefully observing and studying biological structures and life activity phenomena that are difficult to observe under normal circumstances by using certain instruments, materials and medicines under specific environmental conditions. Biology is a natural science based on experiments. [0003] In the process of biological experiments, it is sometimes necessary to grind massive objects such as bones into powder to facilitate experimental operations. The current milling device cannot separate the powdered objects from the bone meal mixture in time during the grinding process. It causes repeated grinding of the powdered items, which reduces the grinding efficiency. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the pr...
