Environment-friendly breaking hammer head

The invention relates to the technical field of engineering machinery, and discloses an environment-friendly breaking hammer head which comprises a body, a cover plate is fixedly connected to the middle of the upper end of the body, a connecting piece is fixedly mounted on the outer side of the middle of the upper end of the cover plate, an air cavity and a dust collection cavity are formed in the body, and a sealing cover is in threaded connection with the middle of the cover plate. Through the arrangement of the dust collection cavity, a piston plate and a groove, when the breaking hammer body hits the ground, the piston plate slides on one side of the air cavity under the action of inertia generated by the gravity of the piston plate, at the moment, the size of the dust collection cavity is increased, large negative pressure is generated, when the breaking hammer body knocks the ground to raise dust, a strong negative pressure area can be formed in the groove through the air inlet pipe, the dust raised aro
