Abstract
A flexible material handling apparatus is arranged to be installed on a full face heading machine. The apparatus includes a material handling member and a linkage member coupled together in a head-tail manner by a joint connection, and the linkage member at the other end may be coupled to a frame of a heading machine. The entire apparatus may be retracted to rest on the side of the machine frame and maintained there by a locking means. The material handling member may be swivelled about two separate vertical axes and brought outwardly to an oblique front position, where one or more locking means may be included to secure the material handling member fixed in place relative to the machine frame.
Claims12
An apparatus for handling excavated material, the apparatus comprising:
- a material handling member arranged to gather excavated material, wherein the apparatus is coupled to a machine frame;
- a linkage member, the material handling member being coupled to the linkage member at a distal end thereof by a first joint connection, the linkage member at its proximal end having at least a part of a joint arrangement to form a second joint connection with the machine frame;
- and
- a locking means arranged to prevent a movement of the material handling member at a working position in relation to the machine frame, the locking means being configured to be coupled between the material handling member and the machine frame, or between the linkage member and the machine frame, or between the material handling member and the linkage member;
- at least one drive means arranged for actuating a movement of the material handling member in a horizontal plane between a parking position and a working position, wherein the at least one drive means includes a first and a second arm pivotably attached together at one end of each arm, the other end of the second arm is pivotably coupled to the material handling member, the other end of the first arm being configured to be pivotably coupled to the machine frame at a base position departing from the second joint connection, the at least one drive means including an actuator arranged between the first and second arms for providing an angular displacement therebetween.
