The working principle of the invention is as follows: the oil is delivered into an oil pipe through an oil pump on an excavator or a loader, and hydraulic oil respectively enters an upper oil way 9 and a lower oil way 10 from the oil pipe, so that the piston 3 is controlled to move in the direction, and the reciprocating impact action on the drill pick 5 is realized; when the piston 3 moves downwards, the control valve 82 controls the vent pipe 85 to be opened so that gas in the gas tank 83 enters the gas cavity 7 from the vent pipe 85, the gas pressure gauge 84 and the connector 86, the pressure in the gas cavity 7 can be enhanced, the downward movement speed of the piston 3 is increased, the power of the piston can be improved, and the impact force and the penetrating power of the drill pick 5 are stronger; when the piston 3 moves upwards, the gas in the gas cavity 7 reversely flows into the gas tank 83 for storage, the barometer 84 monitors the pressure in the gas cavity 7 in real time, and adjusts the control valve 82 to work to control the opening and closing of the vent pipe 85 through the monitoring data of the barometer 84, and in the process, the gas cavity 7 is not required to be filled with the gas regularly by manpower, so that the manual operation is reduced, and the use is convenient; when the piston 3 moves downwards to impact the drill pick 5, the drill pick 5 is immersed into the ground to drive the left machine plate 1 and the right machine plate 2 to synchronously move downwards, so that the bottom plate 1211 positioned at the bottom ends of the left machine plate 1 and the right machine plate 2 is in contact with the ground, in the process, the reaction force applied to the left machine plate 1 and the right machine plate 2 is buffered through the spring 1214, the damage of the drill pick 5 to the cylinder body 4 and the piston 3 can be effectively reduced, the service lives of the cylinder body 4 and the piston 3 are further protected and prolonged, and the splash fragment powder and the like generated in the using and crushing process of the drill pick 5 can be blocked by utilizing the bottom plate 1211, so that the situation that the using effect and the penetrating power of the drill pick 5 are deteriorated due to the fact that the splash fragment powder and the like enter the cylinder body 4 is prevented from occurring; when the whole body is required to be connected to an excavator or a loader, the rotating arm and the fixed arm on the front end of the excavator respectively correspond to two pin holes 134, wherein the arc-shaped fixture block 15 on the rotating fixed shaft 14 can limit the fixed arm and rapidly correspond to one pin hole 134, then the fixed arm and the breaking hammer are integrally connected and fixed by inserting one pin shaft 133 into the pin hole 134, and the subsequent inserting and installation of the positioning pin 131 is facilitated, next, the rotating arm on the front end of the excavator corresponds to another pin hole 134 and then the rotating arm and the breaking hammer are integrally connected and fixed by inserting another pin shaft 133 into the pin hole 134, the positioning pin 131 is integrally inserted and installed on one end of the two pin shafts 133, the whole positioning of the two pin shafts 133 is completed, the connecting sleeve seat 132 is not only convenient for the installation of the positioning pin 131, but also can improve the stability between the positioning pin 131 and the two pin shafts 133, compared with the prior art, the number of the positioning pins 131 is reduced, the connection, the disassembly and the assembly are convenient, and the working efficiency is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
