Abstract
The disclosure relates to a chute liner for mounting on a shelf of a material transfer chute. The shelf has at least one locking formation aperture formed therein. The chute liner has a base for mounting on the shelf. The base has an operatively upper surface that comes into contact with material passing through the chute and an opposed operatively lower surface. The base has at least one mounting formation that depends from the operatively lower surface of the base that defines a passage which in use is passed through the locking formation aperture in the shelf. The chute liner also has a locking member passed through the passage until it operatively engages the mounting formation to lock the base to the shelf.
Claims23
A chute liner for mounting on a shelf of a chute with shelves including at least one locking formation aperture formed therein, the chute liner comprising:
- a base for mounting on the shelf and an arm extending away from the base to a free end, the base having an operatively lower surface and an opposed operatively upper surface that contacts material passing through the chute, the base and the arm being configured to retain a portion of material passing through the chute thereon, at least one mounting formation depending from the operatively lower surface of the base that is in use passed through the locking formation aperture in the shelf, wherein the mounting formation forms a passage extending therethrough below the shelf, with one side of the passage being formed by a lower surface of the shelf;
- and
- a locking member that is displaced into the passage of the mounting formation in use to operatively engage the mounting formation and lock the base to the shelf.
A shelf and liner arrangement for a chute with shelves, the shelf and liner arrangement comprising:
- a shelf having an inner end mounted on a chute wall and a free outer end spaced away from the chute wall, the shelf having at least one locking formation aperture formed therein;
- and
- a chute liner mounted on the shelf, comprising:
- a base mounted on the shelf and an arm extending away from the base to a free end, the base having an operatively lower surface and an opposed operatively upper surface that contacts material passing through the chute, the base and the arm being configured to retain a portion of material passing through the chute thereon during operation of the chute, at least one mounting formation depending from the operatively lower surface of the base that is in use passed through the locking formation aperture in the shelf, wherein the mounting formation forms a passage extending therethrough below the shelf, with one side of the passage being formed by a lower surface of the shelf;
- and
- a locking member received in the passage and operatively engaging the mounting formation to lock the chute liner to the shelf.
