1Reliability

If spring energy absorbing buffers or elastic buffering pads are used to absorb impact energy, then the device can provide buffering function, but the service life is short and components must be replaced frequently when impact energy is too high

Engineering Contradiction:

Solution Approach 1:

The buffering system is divided into three independent auxiliary components connected in sequence: first auxiliary component with arc-shaped rod, second auxiliary component with annular sleeve and pouring weight, and third auxiliary component with buffering box. Each component absorbs impact energy through different mechanisms, distributing the load and preventing single-point failure, thereby extending service life under high impact energy conditions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second auxiliary component uses hydraulic oil to convert impact energy into gravitational potential energy by lifting the pouring weight. This hydraulic-mechanical energy conversion mechanism provides reliable buffering with longer service life compared to traditional elastic buffers, as the hydraulic system can handle high impact energies without component fatigue.
