Novel sample preparation pulverizer

Abstract

The invention discloses a novel sample preparation pulverizer. The pulverizer comprises a rack, a grinding part, a discharging part and a driving part. The grinding part is fixed to the rack by meansof a damping spring, a grinding bowl, an impact block, an impact ring and a discharging slide carriage are arranged inside the grinding part, under the driving effect of the driving part, the grindingbowl, the impact block and the impact ring are driven to vibrate, due to the fact that a powder discharge gap is formed between a bowl bottom and a bowl body of the grinding bowl, the bowl bottom canrotate within a certain range under the vibration effect relative to the bowl body, the movable bowl bottom can effectively avoid sample blocking, and discharging is smooth, so that a ground powder sample inside the bowl body is discharged to the discharging slide carriage along with the powder discharging gap and discharged to the discharging part along with a discharging hole correspondingly formed in the discharging slide carriage, and then the sample is collected into a sample tank. The novel sample preparation pulverizer effectively overcomes the technical defects that in the prior art,a sample preparation pulverizer cannot perform automatic collection and cleaning is not convenient and has the good market application prospect.

Description

technical field [0001] The present invention relates to the technical field of sample preparation crushing equipment, and more specifically relates to a novel sample preparation crushing machine. Background technique [0002] The sample crushing equipment is a machine specially used to crush metal or non-metallic substances with a certain hardness. The traditional sample crushing machine needs to manually pour the sample into the material bowl, and then press the upper cover to start the equipment. , the eccentric block in the vibration box vibrates when it rotates, and the vibration is transmitted to the material bowl. The impact block, impact ring and bowl in the material bowl continuously collide, and the sample is ground to the analysis sample during the continuous impact. [0003] However, the traditional sample pulverizer needs the operator to take out the whole material bowl after grinding, pour out the sample, and then clean the bowl, impact block, impact ring and up...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional sample pulverizer needs the operator to take out the whole material bowl after grinding, pour out the sample, and then clean the bowl, impact block, impact ring and upper cover, which greatly increases the operator's work time. Labor intensity leads to low working efficiency of the sample pulverizer, easy loss of samples, and pollution of the environment
