Assembled compound pendulum slow-release jaw breaker

Abstract

The invention relates to an assembled compound pendulum slow-release jaw breaker adopting an assembled structure for replacing a cast steel machine frame or weld machine frame. The jaw breaker comprises a jaw breaker body. A front block body and a rear block body in the jaw breaker body are located on damping supports through damping cushions correspondingly. Two side steel plates located betweenthe front block body and the rear block body are fixed through high-strength bolts and cylindrical pins in a combined mode. The jaw breaker has the advantages that firstly, the defects that cast steelmachine frames are difficult to overturn technically and turn around, potential machining safety hazards exist and the machining precision is low are overcome, and the phenomenon that cracking of weld machine frames is prone to occurring is avoided; and secondly, the problem that assembling bolts are loosened due to huge impact vibration in the using process of the assembled jaw breaker is fundamentally solved, and the vibration noise of the jaw breaker and impact to the damping supports is reduced to the greatest extent.

Description

technical field [0001] The invention relates to an assembled compound pendulum slow-release jaw crusher which adopts an assembled structure instead of a cast steel frame or a welded frame, belonging to the field of jaw crusher manufacturing. Background technique [0002] The casing of the traditional compound pendulum jaw crusher adopts a cast steel frame or a welded frame. The disadvantage is: in the actual processing process of the cast steel frame, the plane of the fixed plate of the casing and the internal groove of the rear frame need to be processed, but the overall casing is large in size - several meters long, wide, high, and heavy ---It weighs several tons, it is difficult to turn over and turn around during processing, and there are hidden dangers in processing safety and low processing accuracy; while the welding frame is easy to crack in actual use, resulting in the failure of the whole machine. Secondly, when the whole machine is fixed, the traditional compound...

The disadvantage is: in the actual processing process of the cast steel frame, the plane of the fixed plate of the casing and the internal groove of the rear frame need to be processed, but the overall casing is large in size - several meters long, wide, high, and heavy ---It weighs several tons, it is difficult to turn over and turn around during processing, and there are hidden dangers in processing safety and low processing accuracy; while the welding frame is easy to crack in actual use, resulting in the failure of the whole machine

Secondly, when the whole machine is fixed, the traditional compound pendulum jaw crusher is fixed with M48 anchor bolts, but because the compound pendulum jaw crusher has great impact and vibration in actual use, the anchor bolts are easy to loose
