Abstract

Vibratory classifier apparatus are provided, e.g., for classification of materials such as wet or dry aggregate materials. In some embodiments, a drive system of the vibratory classifier apparatus includes a housing that can optionally be modified to allow access to a belt or other components of the drive system.

Claims (28)

1 . A vibratory classifier comprising:

a first sidewall;

a second sidewall separated from said first sidewall by a transverse distance;

at least one screen disposed at least partially between said first sidewall and said second sidewall;

an eccentric weight assembly at least partly supported by at least one of said first sidewall and said second sidewall;

a motor configured to drive said eccentric weight assembly, said motor being operably coupled to said eccentric weight assembly by an endless belt; and

a housing having an open configuration and a closed configuration, wherein in said open configuration at least a portion of said endless belt is accessible to an operator, wherein in said closed configuration said housing substantially surrounds said endless belt, said housing comprising:

a first housing portion; and

a second housing portion pivotally coupled to said first portion at a pivot axis; wherein said first housing portion is pivotable about said pivot axis relative to said second housing portion between said closed configuration and said open configuration.

2 . The vibratory classifier of claim 1 , wherein said first housing portion comprises first and second vertical planar walls and a first curved wall extending between said first and second vertical planar walls.

3 . The vibratory classifier of claim 2 , wherein said second housing comprises a second curved wall, wherein in said open configuration, said second curved wall is disposed at least partially between said first curved wall and said pivot axis.

4 . The vibratory classifier of claim 3 , wherein said first housing is disposed at least partially above said second housing in said open configuration.

5 . The vibratory classifier of claim 1 , wherein said first housing is disposed at least partially above said second housing in said open configuration.

6 . The vibratory classifier of claim 1 , further comprising a belt tensioning assembly configured to modify a tension of said endless belt.

7 . The vibratory classifier of claim 6 , wherein said belt tensioning assembly is disposed at least partially inside said housing in said closed configuration.

8 . The vibratory classifier of claim 7 , wherein said belt tensioning assembly accessible by an operator in said open configuration.

9 . The vibratory classifier of claim 7 , wherein said belt tensioning assembly is at least partially supported by said housing.

10 . The vibratory classifier of claim 1 , wherein said belt tensioning assembly is at least partially supported by said housing.

11 . The vibratory classifier of claim 1 , wherein said first housing portion is selectively retainable in said open configuration.

12 . The vibratory classifier of claim 11 , wherein said first housing portion is selectively retained in said open configuration by a removable fastener selectively at least partially extended through said first and second housing portions.

13 . The vibratory classifier of claim 1 , wherein said first housing portion is selectively retainable in said closed configuration.

14 . The vibratory classifier of claim 1 , wherein said first housing portion comprises a first flange and said second housing portion comprises a second flange, wherein said first and second flange are adjacent in said closed configuration and remote in said open configuration, and wherein said first housing portion is selectively retainable in said closed configuration by releasably fastening said first flange to said second flange.

15 . The vibratory classifier of claim 1 , further comprising a central section, wherein said first housing portion is removably mountable to said central section in said closed configuration.

16 . The vibratory classifier of claim 15 , wherein said first housing comprises a first flange and said central section comprises a second flange, wherein said first and second flange are adjacent in said closed configuration and remote in said open configuration, and wherein said first housing portion is selectively retainable in said closed configuration by releasably fastening said first flange to said second flange.

17 . The vibratory classifier of claim 16 , wherein said first housing portion comprises first and second vertical planar walls and a first curved wall extending between said first and second vertical planar walls.

18 . The vibratory classifier of claim 17 , wherein said second housing comprises a second curved wall, wherein in said open configuration, said second curved wall is disposed at least partially between said first curved wall and said pivot axis.

19 . The vibratory classifier of claim 18 , wherein said first housing is disposed at least partially above said second housing in said open configuration.

20 . The vibratory classifier of claim 15 , wherein said first housing is disposed at least partially above said second housing in said open configuration.
