A grinding device for animal sample detection

Abstract

The invention relates to a grinding device for animal sample detection, comprising: a fixed shaft, on which two rotating drums are rotatably connected, a transmission component is arranged between the two rotating drums, and a spiral groove is formed on the fixed shaft, which is away from the spiral The end face of the drum of the groove is provided with a shaft sleeve, a plurality of grinding rings are sleeved on the drum, and the plurality of grinding rings are threaded together through a synchronizing rod, and the end of the synchronizing rod is slidably connected to the drum around the drum, and the two grinding rings are connected to the drum. A compression spring is arranged on the synchronizing rod between the two sides; a second guiding structure is arranged between the grinding ring and the rotating drum, and a grinding drum is sleeved on the rotating drum. One end is slidably connected with the helical groove, the other end is sleeved on the shaft sleeve, and a torsion spring is sleeved on the fixed shaft with the helical groove, and the torsion spring is connected with the fixed shaft and the grinding cylinder; it also includes a drive assembly, the output of the drive assembly is also sleeved. The end and the shaft sleeve are connected by transmission. The device improves the grinding efficiency of the material and prevents the material from being piled up.

Description

technical field [0001] The invention relates to the field of animal sample processing devices, in particular to a grinding device for animal sample detection. Background technique [0002] In the medical field, animal samples are often tested during experiments. When testing animal samples, solid animal tissues, such as bone tissue, must first be ground to prepare for the subsequent extraction of animal tissues. [0003] However, the existing grinding device grinds the material between the two grinding parts through two grinding parts. When grinding, because the input material contains materials with different hardness and size, the gap between the grinding parts of the traditional grinding device The distance is constant, that is, it can only efficiently process materials of one size. When the proportion of large and fast materials in the input materials is large, it will lead to low grinding efficiency, resulting in piled materials, resulting in material jams. Problems, t...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a grinding device for animal sample detection. During grinding, the grinding ring reciprocates left and right to grind and deduce the material, and at the same time adjust the size of the grinding gap of the annular grinding chamber to solve the existing grinding problem. The grinding efficiency of the device is low, and it is easy to produce the problem of stacking and jamming
