It has the advantages of easy use, simple and reliable structure, and high measurement efficiency.

[0014] (2) The present invention has a buffer block fixedly provided on the top of the supporting claw near the storage rack for use with the unloading roller slope. The buffer block prevents the supporting claw from directly colliding with the unloading roller slope, thereby reducing the collision wear of the unloading roller slope and improving the service life of the device.

[0015] (3) The storage rack of the present invention is provided with a buffer slope, which can prevent the roller from directly impacting the storage rack, thereby increasing the service life of the storage rack and reducing the generation of noise. BRIEF DESCRIPTION OF THE DRAWINGS
