Crushing gap adjusting device of impact crusher

Abstract

The invention discloses a crushing gap adjusting device of an impact crusher, and the device is used for adjusting the distance between an impact plate and an impact plate hammer. The device comprisesa cross beam, an adjusting mandrel mechanism, an external suspension mechanism and a driving adjusting mechanism, the adjusting mandrel mechanism comprises an adjusting mandrel, a lifting lug, a partition plate, a partition plate pin shaft and a partition plate pin shaft mounting piece; a partition plate support is arranged on the adjusting mandrel; the partition plate comprises a partition platepin shaft clamping part and an adjusting mandrel clamping part; and the external suspension mechanism comprises a screw rod, a seat cylinder and a spring. According to the crushing gap adjusting device of the impact crusher, the gap between the impact plate and the impact plate hammer in the impact crusher can be flexibly adjusted through the adjusting mandrel mechanism, the labor intensity of workers can be reduced through the driving adjusting mechanism, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, and more specifically relates to a crushing gap adjustment device for an impact crusher. Background technique [0002] The impact crusher has the advantages of simple structure, large crushing ratio, low energy consumption, high output, and cubes after crushing. It can be used in mining, cement, construction, refractory materials, coal, glass and other industrial sectors. It is used for crushing and finely crushing various medium-hard materials whose compressive strength is not higher than 100Mpa, such as limestone, clinker, slag, coke, coal, etc. [0003] At present, the crushing adjustment gap mechanism of the domestic impact crusher is mechanically adjusted, and the impact plate and the impact blow bar are vulnerable parts, which wear quickly, and the wear causes the gap to increase. It is often necessary to adjust the gap between the impact plate and the impact blow bar. The ga...

Problems solved by technology

[0003] At present, the crushing adjustment gap mechanism of the domestic impact crusher is mechanically adjusted, and the impact plate and the impact blow bar are vulnerable parts, which wear quickly, and the wear causes the gap to increase. It is often necessary to adjust the gap between the impact plate and the impact blow bar. The gap between the impact plate and the impact blow bar needs to be adjusted for different crushing purposes, feeding conditions, final products, operating conditions and rock crushing characteristics, so the adjustment of the gap between the impact plate and the impact blow bar is relatively frequent

However, the existing impact crushers do not have a convenient mechanism for adjusting the gap between the impact plate and the impact blow bar.
