AI Technical Summary
In existing technologies, setting the elasticity and length of the elastic rope is difficult, which makes it impossible for the sample trough to rotate smoothly in the reverse direction or maintain the upward orientation of the sampling port during the sampling process, thus affecting the efficiency of grain sample introduction.
The system uses a pull rope connected to a rotating wheel, which is connected to the base plate via a torsion spring. When the sliding frame moves the sample cell, the torsion spring stores elastic potential energy, and the pull rope wraps around or releases on the rotating wheel, maintaining the controllable movement of the sample cell and avoiding unsmooth movement caused by improper elasticity and length settings of the elastic rope.
This ensures that the sample trough remains within a controllable range during its up-and-down movement, maintains a stable position at the sampling port, and ensures that grain samples are smoothly introduced into the hopper, avoiding motion failure caused by improper setting of the elastic rope.
