Description

Technical Field

[0001] This utility model relates to the field of grinding instrument technology, specifically to a multi-sample disposable grinding instrument. Background Technology

[0002] Hair grinding machines are devices used to grind and break down human or animal hair. Currently, the examination and judgment of drug users mainly rely on saliva, blood, and hair. Among them, saliva testing has a short time frame, blood testing is relatively complicated, and hair testing has a long time frame and is easy to obtain. However, hair testing requires the hair to be broken down before further testing. Currently, existing technologies for hair grinding all use manual grinding fixtures, and the grinding fixtures are relatively traditional and not targeted, which greatly affects the grinding efficiency and quality, and may even affect the accuracy of the test.

[0003] According to a portable hair grinder with application number 202420202581.6, when grinding hair in a test tube, the test tube is placed in the placement port and fixed with a pressure plate. Then, the placement plate and pressure plate can be limited and fixed by the limiting rod on the collar, so that the test tube can continuously make an eccentric swinging motion. With the addition of a rubber pad, the test tube is more stable, resulting in a better grinding effect on the hair. Moreover, no parts need to be replaced during grinding, making the grinder more convenient to use. After grinding, the test tube can be easily disassembled and removed, making it convenient to collect the ground hair.

[0004] However, the above-mentioned grinders have certain shortcomings. When grinding, the sample is put into a grinding bottle, and grinding balls and grinding fluid are added to the bottle. After grinding, the sample needs to be poured out of the grinding bottle. However, this method will leave sample residue on the inner wall of the grinding bottle, which is a certain shortcoming. To address this, we propose a multi-sample disposable grinder. Utility Model Content

[0046] In this embodiment, the cover 22 and the lock can be used to connect and fix the cover 22 to the grinding instrument housing 1.

[0047] In summary, when using this multi-sample disposable grinder, first connect it to an external power supply via the power cord. Then, open the cover 22 after unlocking the latch. After opening the cover 22, take out several grinding tubes 12 according to the number of samples to be processed. Then, unscrew the cap 13 at one end of the grinding tube 12 and load the sample to be ground, grinding liquid, and grinding balls into the grinding tubes 12 respectively. After the samples are loaded into the grinding tubes 12, tighten the cap 13 to seal the grinding tubes 12. Then, insert the grinding tubes 12 containing the samples into the holder 11. Then, flip the pressure plate 19 and press the grinding tubes 12 into place using the pressure strip 21. Finally, fix the pressure plate 19 with the fixing bolts 20 to complete the sample fixation. Then, close the cover 22 and fix it with the latch. After fixation, start the motor via the control panel 23. 8 drives the output shaft 9 and the turntable 101 to rotate. The rotation of the turntable 101 causes the lever 102 to slide in the groove of the slide sleeve 7 and drive the slide sleeve 7 to move back and forth. Thus, the slide sleeve 7 drives the fixed seat 6 to swing back and forth through the cooperation of the slide plate 5 and the slide rod 4. While swinging, the grinding balls in the grinding tube 12 come into contact with the sample for grinding, thus completing the rapid grinding. After the sample grinding is completed, open the latch and the shell cover 22, and then loosen the fixing bolt 20 to flip the pressure plate 19 so that the grinding tube 12 can be removed from the card seat 11. After removing the grinding tube 12, unscrew the can cover 13 and rotate the sleeve cover 14 to loosen it through the threads. Push the sleeve cover 14 so that the sample, grinding liquid and grinding balls in the grinding tube 12 are pushed out of the grinding tube 12 through the push rod 15 and the piston push plate 16. Then the ground sample can be taken out.
