Description

Transmission shield for jaw crusher and jaw crusher Technical Field The utility model relates to the technical field of mining equipment, in particular to a transmission shield for a jaw crusher and the jaw crusher. Background Jaw crusher is used as core equipment in mine industry and is widely used in coarse crushing of ore. The drive train is usually driven by a belt and transmits power through the cooperation of a driving pulley and a driven pulley. However, jaw crushers are often in severe environments where dust is much, vibration is large, foreign matter is easy to invade, a transmission belt is easy to damage due to impact of foreign matter such as broken stone, metal fragments and the like, and a belt running at a high speed constitutes a serious potential safety hazard to operators. For this reason, shields are commonly used in the prior art to protect the drive belt and flywheel. The shields in the current market mostly adopt split left and right structures, the mounting process of the shields needs to be aligned with the left and right shields in sequence and fixed, the operation is complicated, the shields need to be completely detached when the belt is replaced, and the maintenance efficiency is low. In addition, the shield is easy to deform in transportation or long-term use due to insufficient structural strength, and the protection effect is affected. The landing leg fixed mode and the connection structure of current guard shield are mostly rigid design, are difficult to adapt to the installation demand of different model jaw breaker, and for example flywheel and band pulley interval's change can't nimble the regulation, lead to the commonality relatively poor. In view of the above, there is a need in the art for improvements.
