Abstract
A belt conveyor skirtboard apron assembly comprising at least two vertically oriented U-shaped brackets mounted at spaced positions on the skirtboard, preferably inclined inwardly toward the edge of the conveyor belt, a corresponding number of tension arms each mounted in one of the brackets by a wedge that extends through the bracket sidewalls and the tension arm, an apron-mounting channel extending between and affixed to the lower end of each tension arm, and a resilient, flexible apron replaceably mounted on the channel by means of two mounting strips affixed to the apron and slidably fitted into the channel; the vertical position of the apron is adjusted to compensate for wear, without requiring shutdown of the conveyor, by driving the wedges further into the brackets.
Claims8
A skirtboard apron assembly for a belt conveyor for granular material of the kind comprising a rigid skirtboard positioned a short distance above the conveyor belt and a resilient, replaceable apron mounted on and extending downwardly from the skirtboard to close the gap between the skirtboard and the belt, the apron assembly, in assembled condition, comprising:
- a plurality of U-shaped brackets mounted at spaced positions along the skirtboard, each bracket having a base and two side walls defining a generally vertically oriented receptacle, the bracket side walls including aligned wedge-receiving apertures;
- a corresponding plurality of tension arms, each positioned in one of the bracket receptacles and each including a wedge-receiving aperture aligned with the wedge-receiving apertures in the bracket sidewalls, each tension arm being affixed to a horizontally oriented apron-mounting channel extending parallel to the conveyor belt surface;
- a corresponding plurality of wedges, each inserted through the wedge-receiving apertures in one mounting bracket and in one tension arm to mount that tension arm in the bracket;
- and an apron having a longitudinally extending mounting element affixed thereto, the mounting element being slidably fitted into the channel of each tension member to suspend the apron from the tension member;
- the vertical position of the apron being determined by the extent to which the wedges are inserted into the mounting brackets.
