Abstract

A frame for reciprocating sieve assembly comprises a first side member ( 300, 308 ) that is elongate and extends longitudinally; a second side member ( 302, 310 ) that is elongate and extends longitudinally; a third side member ( 304, 312 ) that is elongate and extends transversely; a fourth side member ( 306, 314 ) that is elongate and extends transversely; a first hanger mount ( 206 L, 210 L) coupled to and extending between the first side member and the third side member; a second hanger mount ( 208 L, 212 L) coupled to and extending between the first side member and the fourth side member; a third hanger mount ( 206 R, 210 R) coupled to and extending between the second side member and the third side member; and a fourth hanger mount ( 208 R, 212 R) coupled to and extending between the second side member and the fourth side member; wherein the first side member, the second side member, the third side member, and the fourth side member are comprised essentially of an aluminum alloy; and wherein the first hanger mount, the second hanger mount, the third hanger mount, and the fourth hanger mount are comprised essentially of a ferrous alloy.

First claim

We claim:

1. A frame for reciprocating sieve assembly comprising:
a first side member ( 300 , 308 ) that is elongate and extends longitudinally;
a second side member ( 302 , 310 ) that is elongate and extends longitudinally;
a third side member ( 304 , 312 ) that is elongate and extends transversely;
a fourth side member ( 306 , 314 ) that is elongate and extends transversely;
a first hanger mount ( 206 L, 210 L) coupled to and extending between the first side member and the third side member;
a second hanger mount ( 208 L, 212 L) coupled to and extending between the first side member and the fourth side member;
a third hanger mount ( 206 R, 210 R) coupled to and extending between the second side member and the third side member; and
a fourth hanger mount ( 208 R, 212 R) coupled to and extending between the second side member and the fourth side member;
wherein the first side member, the second side member, the third side member, and the fourth side member are comprised essentially of an aluminum alloy; and
wherein the first hanger mount, the second hanger mount, the third hanger mount, and the fourth hanger mount are comprised essentially of a ferrous alloy.

2. The frame of claim 1 , further comprising:
a first plurality of fasteners ( 1012 , 1018 , 1312 , 1318 ) fastening the first hanger mount ( 206 L, 210 L) to the first side member; and
a second plurality of fasteners ( 1030 , 1330 ) fastening the first hanger mount ( 206 L, 210 L) to the third side member.

3. The frame of claim 1 , further comprising:
a third plurality of fasteners ( 1112 , 1118 , 1212 , 1218 ) fastening the second hanger mount ( 208 L, 212 L) to the first side member; and
a fourth plurality of fasteners ( 1130 , 1230 ) fastening the second hanger mount ( 208 L, 212 L) to the fourth side member.

4. The frame of claim 1 , further comprising:
a fifth plurality of fasteners ( 1012 , 1018 , 1312 , 1318 ) fastening the third hanger mount ( 206 R, 210 R) to the second side member; and
a sixth plurality of fasteners ( 1030 , 1330 ) fastening the third hanger mount ( 206 R, 210 R) to the third side member.

5. The frame of claim 1 , further comprising;
a seventh plurality of fasteners ( 1112 , 1118 , 1212 , 1218 ) fastening the fourth hanger mount ( 208 R, 212 R) to the second side member; and
an eighth plurality of fasteners ( 1130 , 1230 ) fastening the fourth hanger mount ( 208 R, 212 R) to the fourth side member.

6. The frame of claim 1 , further comprising:
a first bracket ( 214 , 216 ) that is fixed to the first side member ( 300 , 308 ) and extends downward therefrom; and
a second bracket ( 214 , 216 ) that is fixed to the second side member ( 302 , 310 ) and extends downward therefrom.

7. The frame of claim 6 , further comprising:
a first grain pan ( 222 , 224 ) fixed to the first bracket ( 214 , 216 ) and the second bracket ( 214 , 216 ).

8. The frame of claim 7 , wherein the first bracket ( 214 , 216 ), the second bracket ( 214 , 216 ), and the first grain pan ( 222 , 224 ) are formed of a ferrous sheet metal.

9. The frame of claim 8 , wherein the first grain pan ( 222 , 224 ) has a strength of at least 30 kpsi.

10. The frame of claim 9 , wherein the first grain pan ( 222 , 224 ) has a strength of at least 50 kpsi.

11. The frame of claim 7 , wherein the first grain pan ( 222 , 224 ) is fixed in a forwardly and downwardly sloping orientation with respect to the first side member ( 300 , 308 ) and the second side member ( 302 , 310 ).

12. The frame of claim 1 , wherein at least one of the third side member ( 304 , 312 ) and the fourth side member ( 306 , 314 ) comprises an elongate extruded recess ( 604 , 704 , 804 , 904 ) is configured to receive and support an elongate sieve element.

13. The frame of claim 12 , wherein the elongate extruded recess ( 604 , 704 ) opens in a rear-facing direction.

14. The frame of claim 12 , wherein the elongate extruded recess ( 804 , 904 ) opens in an upward-facing direction.

15. The frame of claim 1 , wherein the first side member ( 300 , 308 ) and the second side member ( 302 , 310 ) are extruded members, and further wherein the first side member ( 300 , 308 ) and the second side member ( 302 , 310 ) define a tubular section ( 400 , 500 ) in cross-section.

16. The frame of claim 15 , wherein the tubular section ( 400 , 500 ) extends substantially an entire length of the first side member ( 300 , 308 ) and the second side member ( 302 , 310 ).

17. The frame of claim 1 , wherein at least one of the third side member ( 304 , 312 ) and the fourth side member ( 306 , 314 ) are extruded members, and further wherein said at least one of the third side member and the fourth side member define a hollow interior region ( 600 , 700 , 800 , 900 ) in cross-section.
