The shell of Yantai Rocka's breaker is made of high-strength manganese steel plate, which has good wear resistance and durability. The shape processing adopts the German imported CNC flame cutting machine; the welding groove adopts the Japanese "groove robot" to weld the welded parts, so as to achieve uniformity and ensure the quality of processing and welding. The shell is well sealed to effectively prevent dust and protect the impact mechanism and bushing from premature wear and damage.

The structure of connecting the broken hammer shell includes the symmetrical left and right broken shells. The left and right broken shells are connected to each other. One end is connected to the left and right broken shells. Each position has a left connector and a correct one. The connecting block and the other hammer shell part are respectively fixed on the last left and right connecting plates; the left connecting plate and the right connecting plate are equipped with several connecting holes, and the left connecting plate and the right connecting plate pass through the connecting holes Connect the broken hammer frame, the hammer frame is installed on the assembly pin. The interval between the hammer shell and the excavator hammer frame, when used, will be affected by the hammer shell and the broken hammer frame together, reducing the impact of a single product, slowing down the damage rate of the product, extending the service life of the product, and reducing the cost of the product ; At the same time, if the product is damaged during use, only the damaged part can be replaced.
