The toggle plate of the jaw crusher is also called the thrust plate or the toggle plate
and is also called the safety plate. Although the jaw crusher has a simple structure and simple working principle, from the transmission device to the adjustment device to the safety device , Zhengzhou
Tengfei
Every link is reasonably designed and closely coordinated, thereby improving the crushing efficiency of the jaw crusher.
The thrust plate is the most difficult item to replace. In the jaw crusher, the connecting rod is an integral part of the crushing equipment. To remove the thrust plate, you must first unscrew the baffle bolts, cut off the dry oil lubricating oil pipe, and lift the thrust plate. Hang it on the crane lifting hook or other lifting equipment, and then loosen the spring at one end of the horizontal connecting rod, pull the movable jaw to the direction of the fixed jaw plate, and take out the thrust plate. If the rear thrust plate is to be taken out, the connecting rod, front thrust plate and movable jaw should be pulled apart together, and the rear thrust plate should be taken out. After the thrust plate is removed, cut off the thin lubricating oil pipe and cooling water pipe, and use a bracket under the connecting rod. Support it, and then remove the connecting rod cover. If the problem occurs, it needs to be repaired and solved in time. The replacement must be organized and the steps must be clear.
Various unexpected situations will occur when the jaw crusher is working. For example, the broken material is too large and too hard, causing the discharge port to be blocked, which will cause the entire jaw crusher system to be paralyzed. At this time, the jaw crusher will Safety devices are particularly important. The safety device of the jaw crusher mainly relies on the help of the toggle plate. The toggle plate is made of ordinary cast iron, which is thin in the middle and thick on both sides. When the above situation occurs, the toggle plate will break, causing the jaw crusher to stop working and protecting the jaw crusher
Thrust of the grinder The plate is the two connecting components connecting the connecting rod, the movable jaw and the frame. It plays the role of transmitting energy (for simple pendulum jaw crusher) and grinding side force. The thrust plate is subjected to pressure when working. The thrust plate also serves as a safety device. When non-abrasive objects such as metal blocks enter the grinding chamber of the jaw crusher, in order to protect the safety of important working components such as the equal shaft, the thrust plate is required to break due to overload. This prevents the remaining components from being damaged. Therefore, the material requirements for the thrust plate are not too high, and most of its materials are cast iron.
The structural form of the thrust plate of the grinding machine is either cast as a whole or combined. According to the shape and structure of the thrust plate, there are mainly single-piece combined double-body type and combined three-body type. , the minimum cross-sectional size of the thrust plate is designed based on the fact that the grinder can break on its own when overloaded.
