Problems solved by technology

[0002] In the rock formation breaking construction of mining and foundation construction, rippers are widely used for rock formations that are not too hard due to their high efficiency. The main equipment equipped with rippers are bulldozers and excavators. Can not make full use of the weight of the equipment to obtain larger cutting force, in order to overcome the above technical problems, there have been rock breakers such as publication numbers CN106979010A. The rock breaking operation can be carried out inside, and the weight of the rock breaking machine can be fully utilized to obtain a large cutting force
[0003] Due to its structural characteristics, in order to meet most transportation conditions, the rock breaker takes walking as the dividing point. The area where the main function is located is long and is often located at the rear of the trailer. The front of the trailer is relatively small. The other end of the rock breaker is usually It will be located in front of the trailer, so the length of the front end will be limited, resulting in a large difference in length between the two ends. The area where the ripper can break rocks when the rock breaker does not move in the hollow area is the effective rock-breaking area. The area of ​​the rock area is usually smaller than the hollow area, and the center point of the effective rock-breaking area is located at or close to the center of gravity of the rock-breaking machine. The center point is at or close to the center of gravity of the rock breaker. In some cases, it is limited by the total weight of the rock breaker, and the weight of the counterweight will also be limited, so that it is difficult for the center of gravity of the effective rock breaking area to be at or close to the center of gravity of the rock breaker, so that the ripper Can not make full use of the weight of the rock breaker to obtain a large cutting force
