Feed bin anti-bridge device

A method of dislodging entrapped particulate material from an assembly of a bin and a hopper for dispensing the particulate material, wherein the assembly of the bin and the hopper is supported on a foundation by a plurality of support legs, the method comprising:

• lifting at least one of the plurality of support legs off of the foundation by a predetermined amount by using at least one lifting mechanism that is resting on the foundation and operatively attached to one of the plurality of support legs;
• and
• dropping the at least one support leg into a free fall down on to the foundation using the lifting mechanism, whereby an impact shock thus produced is transmitted to the assembly of the bin and the hopper through the support leg and promote dislodging of any of the particulate material that may be in a non-flowable state to enhance dispensing of the particulate material from the assembly of the bin and the hopper.
