Excited frame, vibratory conveying apparatus for moving particulate material

An excited frame, vibratory conveying apparatus for moving particulate material, comprising:

• an excited frame means having an elongated frame extending in an intended conveying direction defining a first part of an assembly;
• said excited frame means having a known center of mass;
• an elongated conveying member supported on the elongated frame and extending in the intended conveying direction and defining a second part of the assembly for receiving particulate material at one end and conveying the particulate material in a forward direction to an opposite end;
• said elongated conveying member having a known center of mass;
• first supporting means for resiliently supporting the conveying member on the excited frame means and defining a third part of the assembly to enable the elongated conveying member to reciprocate in the intended conveying direction with respect to the elongated frame;
• said first supporting means comprising a plurality of springs connected to and extending between the elongated frame and the conveying member for resiliently supporting the conveying member on the elongated frame to enable the conveying member on the elongated frame to enable the conveying member to reciprocate in a prescribed path in the intended conveying direction with the conveying member forward and upward in a forward stroke and rearward and downward in a rearward stroke with respect to the excited frame means;
• said springs having a known spring constant and wherein said assembly has a known weight and center of mass;
• a second supporting means for resiliently supporting the excited frame means;
• said excited frame means having a directional vibratory drive means mounted thereon and directly connected to the elongated frame in which the directional vibratory drive means produces vibrating motion along a linear line of force for directly vibrating the elongated frame at a desired frequency relating to the weight of the assembly and spring constant;
• said excited frame means having a mounting means mounting the vibratory drive means on the elongated frame with the linear line of force extending colinearly through the center of masses of the excited frame means and the conveying member and parallel with the prescribed reciprocating path of the conveying member to minimize rocking motion of the conveying element about its center of mass;
• and
• said vibratory drive means being mounted along the line of force spaced from the center of mass of the assembly.
