Description

Technical Field

[0001] The utility model relates to a chain belt driven by a sprocket and a chain and a chain belt conveyor. Background Art

[0002] Belt conveyors are widely used in chemical, mining and logistics fields for the transportation of goods and materials. However, the current use of belt conveyors has certain limitations, such as limited length, limited use environment, and the risk of belt breakage and slippage when transmitting ore materials with relatively high weight, which poses certain safety hazards. Moreover, the limited length limits its use environment. In some necessary occasions, multiple belt conveyors need to be arranged for the transportation of materials, which cannot adapt to the transportation from flat lanes to slope lanes and from slope lanes to flat lanes. In comparison, the more important issue is safety. Therefore, some technicians in this field have proposed a safer chain belt conveyor, which uses gears and chain transmission to overcome the problems of belt breakage, slippage and deviation.

[0003] However, the currently disclosed chain-belt conveyors only use chain conveying, connecting the chain to the belt through a transfer device or other auxiliary mechanism, and indirectly driving the belt to realize material transmission. They are not real chain conveyors. The structure is not compact enough, the effect is unsatisfactory, the transmission efficiency is not high, and the stability is also lacking.
