Bucket elevator conveying chain

Abstract

The invention belongs to the technical field of chains, and particularly relates to a bucket elevator conveying chain. The bucket elevator conveying chain comprises chain links connected in sequence, wherein each chain link comprises two inner chain plates, two outer chain plates, a sleeve and two rotating shafts; and each outer chain plate is provided with a groove chamber one, a grinding unit is arranged in each groove chamber one, and each grinding unit comprises a gear one, a pair of gears two, a grinding plate and grinding teeth. According to the bucket elevator conveying chain, by arranging the grinding units, each grinding unit comprises the gear one, the pair of gears two, the grinding plate and the grinding teeth, each grinding plate rotates through mutual cooperation of the gears one and the pair of gears two so as to drive the grinding teeth to rotate, and the transmission ratio of the gears one to the gears two is 1 to 0.5, so that the rotating speed of the grinding plates is smaller than that of the rotating shafts, therefore, time difference exists between the inner chain plates and the grinding plates, the grinding effect of the grinding teeth on the outer walls of the inner chain plates is further improved, and the service life of the chain is prolonged.

Description

technical field [0001] The invention belongs to the technical field of chains, in particular to a bucket elevator conveying chain. Background technique [0002] Conveyor chains are also made up of a series of bearings, which are fixed by restraining chain plates, and their positional relationship with each other is very precise. Each bearing consists of a pin shaft and a bushing, on which the chain rollers rotate. , the pin shaft and the sleeve are all surface hardened, which allows them to be hinged together under high pressure, and can withstand the load pressure transmitted by the rollers and the impact during engagement. There are a series of conveyor chains of various strengths. Different chain pitches: the minimum chain pitch depends on the requirement for sufficient strength of the sprocket teeth, while the maximum chain pitch is usually determined by the rigidity of the chain plates and general purpose chain. [0003] In the Chinese invention patent (application num...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem that the gap between the existing inner chain plate and the outer chain plate is easy to wear and the chain is exposed to a humid environment for a long time, making the chain easy to rust, the invention proposes a bucket type Elevator Conveyor Chain
