Abstract
The bucket conveyor system is made up of buckets which are pivotally suspended between two chains and run around an endless circuit. The claims are made up of links being connected by pins in elongated holes. This chain can be compressed to make its length less than when it is under tension. The chain is compressed at the loading station to force the buckets into direct contact with each other and allow continuous 10 loading. At the discharge station the chain is put under tension to space the buckets and allow them to be rotated through 360.degree. to empty out their contents. Guides are positioned at the areas where the chain is under compression to stop buckling from occurring. The system is driven by a motor and sprockets which also control the compression or tension of the chain.
Claims12
A bucket elevator conveyor system, comprising:
- (a) a track for moving at least one chain through an endless circuit including a loading station and a discharge station;
- (b) a plurality of buckets pivotally mounted on the chain for movement therewith, and to receive material at the loading station and discharge material at the discharge station and drive means to drive the chain;
- (c) said chain comprising a multiplicity of links connected together by pins pivoting in elongated holes formed in the links such that the length of a section of the chain is greater when in a tensioned condition;
- (d) compression means for compressing a section of the chain into a compression condition at the loading station, the spacing of the buckets being such that when the chain is in said compression condition, adjacent edge portions of the buckets are in contact and when the chain is in said tensioned condition the buckets can be rotated through 360.degree. about an axis on which the buckets are carried.

- (b) a plurality of buckets pivotally mounted on the chain for movement therewith, and to receive material at the loading station and discharge material at the discharge station and chain drive means to drive the chain, the chain drive means comprises a sprocket member powered by a motor;
- (c) said chain comprising a multiplicity of links connected together by pins pivoting in elongated holes formed in the links such that the length of a section of the chain is greater when in a tensioned condition;
- and
- (d) compression means for compressing a section of the chain into a compression condition at the loading station, the spacing of the buckets being such that when the chain is in said compression condition, adjacent edge portions of the buckets are in contact and when the chain is in said tensioned condition the buckets can be rotated through 360.degree. about an axis on which the buckets are carried, said compression means comprising first and second sprockets rotatably mounted at the entry and exit ends of said section of the chain and spaced apart at a distance equivalent to the compressed length of said section of chain, the chain drive means being positioned on the entry side of said chain section.
