A bucket conveyor comprises a drive pulley and at least one guide pulley with endless traction cable means engaged over the guide pulley and the drive pulley. A bucket member or a conveyor trough has an axle thereon on each side and with a pulley on the axle. In one embodiment the pulley is pivotal on the axle and in another embodiment the pulley is fixed on the axle. In addition, the construction includes a guide pin on the trough on each side of the axle and the endless traction cable is trained around each guide pin and has a loop engaged over the pulley between the pins. In this manner the endless cable is guided between the drive pulley and the guide pulley and around the pin of each bucket and over the bucket pulley on an axle of the bucket and around the pin on the opposite side of the bucket pulley. The construction is applicable both for a fixed bucket in respect to the traction cable or a bucket that pivots or swings in respect thereto and in which the bucket pulley is rotatable on its bucket axle.
A bucket conveyor, comprising a drive pulley, at least one guide pulley, endless traction cable means engaged over said drive pulley and said guide pulley, a conveyor trough having an axle, a bucket pulley on said axle, a guide pin on said trough on each side of said axle, said endless traction cable means including a cable trained around each guide pin having a loop engaged over said bucket pulley between said pins to secure said bucket pulley to said cable, wherein said bucket pulley is rotatably mounted on said axle.
A bucket conveyor, comprising a drive pulley, at least one guide pulley, a pair of endless traction ropes engaged over said drive pulley and said guide pulley, a conveyor trough having axles extending from each side thereof, a bucket pulley on each of said axles, guide pins on said trough adjacent each of said axles, defining a spacing between each of said guide pins and said axle, one of said endless traction ropes trained around each guide pin and engaged over said bucket pulley through said spacing to receive said trough to said rope, said conveyor trough being arranged between said traction ropes, and said bucket pulley being rotatably mounted in said bucket axle.
