The body mainly comprises a machine core 4 and two side plates 5, wherein the two side plates 5 are detachably connected to two sides of the machine core 4.
Specifically, the core 4 comprises a cylinder and a piston, the excavator provides high-pressure oil for the core 4 through a hydraulic pipeline, the core 4 comprises the cylinder and the piston, the high-pressure oil drives the piston in the core 4 to reciprocate, the piston impacts a drill rod, impact energy is transmitted to a rock stratum through the drill rod, and then the rock stratum is cracked. Since the movement 4 can directly adopt the existing structure, it is not described again to avoid redundancy.
The two side plates 5 are symmetrically arranged at two sides of the movement 4, the upper part of the side plates 5 is also provided with a first hinge part 51 and a second hinge part 52, the first hinge part 51 is used for being hinged with a small arm (not shown in the figure) of the excavator, and the second hinge part 52 is used for being hinged with an oil cylinder (not shown in the figure) on the small arm.
The two balance weights 7 are symmetrically arranged and are respectively connected with the two side plates 5. In order to facilitate the installation of the counterweight 7, the side plate 5 is provided with a first installation part 8 and a second installation part 9 at intervals, and correspondingly, the counterweight 7 is provided with a first connection part 72 and a second connection part 73 at intervals; the first mounting portion 8 is connected to the first connecting portion 72, and the second mounting portion 9 is connected to the second connecting portion 73.
In the present embodiment, the first mounting portion 8 is located below the second mounting portion 9, and the first connecting portion 72 is located below the second connecting portion 73; the first mounting portion 8 is hinged to the first connecting portion 72, and the second mounting portion 9 is engaged with the second connecting portion 73. Specifically, the first mounting portion 8 is provided with a hinge hole, and the first connecting portion 72 is provided with a hinge shaft rotatably provided in the hinge hole. The second mounting portion 9 has a hook-shaped structure with a hook tip tilted upward, and the second connecting portion 73 has a groove structure with a notch facing downward. When the installation is carried out, the inner side surface 76 of the counterweight 7 is firstly attached to the side plate, the second connecting part 73 is higher than the second connecting part 73 of the side plate 5, the hook tip is aligned to the notch of the groove, and the counterweight 7 is lowered, so that the hook tip is clamped into the groove; at this time, the positions of the first mounting portion 8 and the first connecting portion 72 are exactly corresponding, and the pin shaft passes through the through hole interfaces of the first mounting portion 8 and the first connecting portion 72. When the balance weight is detached, the pin shaft is detached, and then the balance weight 7 is lifted upwards. The second mounting portion 9 and the second connecting portion 73 are capable of engaging with each other, and capable of restricting the movement of the counterweight 7 in the front-rear direction and the lateral direction.
Further, a transition piece 1010 is disposed between the mating surfaces of the second mounting portion 9 and the second connecting portion 73.

Further, the sum of the weights of the two counterweights 7 is greater than the weight of the movement 4. The overall weight of the breaking hammer directly influences the magnitude of the downward pressure of the breaking hammer and the strength of the jumping hammer, and when the weight is larger, the downward pressure of the breaking hammer is larger, and the strength of the jumping hammer is smaller. Since the production cost of the movement 4 is much higher than that of the counterweight 7, the production cost is lower for increasing the weight of the counterweight 7 compared to increasing the weight of the movement 4. In this embodiment, the sum of the weights of the two counterweights 7 is greater than the weight of the movement 4, so that the production cost can be reduced as much as possible under the conditions of ensuring good downward pressure and reducing the strength of the jump hammer.
The counterweight 7 may be made of a casting member, and the upper portion thereof is provided with a lifting lug 76. The manufacturing cost of the counterweight is 6300 yuan/ton, and the total weight of the two counterweights 7 is 2.6 tons.

The weight of the machine core 4 is 2.1 tons, the machine core 4 is formed by cutting high-quality steel pieces, and the manufacturing cost is 21000 yuan/ton. Therefore, the manufacturing cost of the movement 4 is much higher than that of the counterweight 7 and the side plate 5; increasing the weight of the breaking hammer by increasing the weight of the side plates 5 and the counterweight 7 is advantageous to reduce the overall production cost.
Further, referring to fig. 5, in the present embodiment, the front surface of the counterweight 7 is moved backward, so that the edge of the side plate front side 53 protrudes out of the counterweight front side 71. When the breaking hammer is operated, the front part of the breaking hammer is easy to touch with a rock stratum.
