Abstract
The present application relates to a spherical object falling buffer device including a flow-limiting pipe assembly and a central column assembly; wherein the flow-limiting pipe assembly includes a flow-limiting pipe, a redirecting joint and a sphere outlet pipe; a diameter of the flow-limiting pipe is greater than that of the sphere outlet pipe, and an inner surface of the redirecting joint is a conical surface; the central column assembly includes at least a central column arranged in the flow-limiting pipe; a flow-guiding region is provided between the flow-limiting pipe and the central column, and a plurality of gravity flow guide grooves are provided on an outer peripheral surface of the central column. The spherical object falling buffer device may restrict, guide and buffer spherical objects during falling, and avoids collision damage of the spherical objects or the stock bin due to the excessive falling speed of the spherical objects.
