BUFFER DEVICE FOR FALLING SPHERICAL OBJECTS Russian patent published in 2021 - IPC B65G11/20 B65G69/16 G21C19/20 

FIELD: mechanical engineering.

SUBSTANCE: buffer device for falling spherical objects contains a flow-limiting pipe node and a central column node. The flow-limiting pipe node contains a flow-limiting pipe, a redirecting connection and an exit pipe of spherical objects connected in series with each other in the top-down direction. The diameter of the flow-limiting pipe is larger than the diameter of the exit pipe of spherical objects. The inner surface of the redirecting connection is a conical surface. The central column assembly contains a central column located inside the flow-limiting pipe. A flow-directing region is formed between the flow-limiting pipe and the central column. On the outer peripheral surface of the central column, there are many guiding grooves of the gravitational flow. The buffer device for falling spherical objects can limit, direct and dampen spherical objects during the fall, thereby preventing damage as a result of a collision of spherical objects or a charge hopper due to an excessively high speed of falling spherical objects.

EFFECT: buffer device for falling spherical objects provides good protection for spherical objects and the charge hopper as a whole, and has a simple design, and is also convenient to install, which ensures that the requirements for the reliability of buffer loading of spherical objects are met under various operating conditions.
