Abstract
The invention relates to an ejector unit, in particular for a road milling machine, having an ejector that is replaceably mounted on a carrier. In one aspect the ejector is curved in a scoop-like fashion. In another aspect the ejector is reversible upon the carrier to allow the ejector to be reversed after one wear surface is worn, thus presenting a new second wear surface.
Claims47
An ejector for a road milling machine, comprising:
- a concave conveying surface facing in a feed direction;
- and
- a rear mounting side facing away from the conveying surface, the rear mounting side including at least one support surface.
An ejector for a road milling machine, comprising:
- a generally rectangular ejector body having a length and a width, the body having a front conveying side and a rear mounting side, the body being curved along at least part of its length so that the front conveying side is concave lengthwise and the rear mounting side is convex lengthwise;
- and
- a lengthwise extending mounting rib protruding from the rear mounting side, the ejector body being symmetrical about the mounting rib in a widthwise direction so that the ejector body can be reversibly mounted in either of two mounting positions rotated 180° from each other.
An ejector unit for a road milling machine, comprising:
- a carrier adapted to be mounted on a milling drum;
- and
- an ejector replaceably mountable upon the carrier in at least two different operating positions.
An ejector unit for a road milling machine, the milling machine including a milling drum rotatable in a feed direction about a rotational axis, the rotational axis defining an axial direction parallel to the axis and a radial direction extending radially from the axis, the ejector unit comprising:
- a carrier including a mounting foot shaped to be received on the milling drum, and a support portion extending from the mounting foot, the support portion including a forward facing support surface and first and second crossing support recesses defined in the support surface;
- and
- an ejector including a forward facing conveying surface and including first and second rearward extending crossing extensions complementary to and received in the first and second crossing support recesses of the carrier, so that engagement of the crossing extensions with the crossing recesses supports the ejector against both axial and radial motion relative to the carrier.
