ABSTRACT:
A scraper blade assembly for use in a central chain scraper conveyor, especially in a double central chain scraper conveyor, includes a lower and an upper blade part forming respective channels that complement each other at a parting plane between the blade parts into openings for receiving transversely spaced portions of respective horizontal links of the chains. The blade parts have overlapping portions one of which extends across the parting plane and is received in a correspondingly configurated recess juxtaposed with the other overlapping portion. The overlapping portions are provided with aligned holes at least one of which is elongated in direction normal to the parting plane, and bolts extend through these holes parallel to the advancement direction of the conveyor to connect the blade parts to one another. One of the blade parts has additionally one or two further bolts connected thereto, these additional bolts extending normal to the parting plane and into corresponding additional holes in the other blade part. A nut is threaded on each of the additional bolts and connects the same to the other blade part in such a manner that the blade parts are unable to bend at the critical region of the openings for the chain link portions and hence the latter are safely clamped between the blade parts.
