AI Technical Summary
Technical Problem
In grain and oil testing, existing technologies make it difficult to quickly and accurately extract samples of the same volume multiple times, causing inconvenience for staff.
Method used
A quantitative extraction device for grain and oil testing was designed. By setting a threaded top and bottom cover, connecting rod, rubber piston, arc plate and rack structure on the sampling cylinder, and using scale lines and springs, the target volume can be quickly locked to ensure the consistency of the sample amount extracted each time.
Benefits of technology
It improves the work efficiency of staff, ensures the accuracy and consistency of sample volume each time, facilitates the disassembly and cleaning of the device, and has high practical value.
