Example Embodiment

[0013] Examples:

[0014] See figure 1 , Hydraulic breaker, including a middle cylinder block 4 and a front cylinder block 6 which are connected in one body. It also includes a rear nitrogen chamber 1 arranged at the end of the middle cylinder block 4 and a reversing valve arranged above the middle cylinder block 4. The assembly 3 and the piston 8 located in the inner cavity of the middle cylinder 4 and the front cylinder 6, and the front end of the piston 8 is connected to the hammer 7.

[0015] The piston 8 and the inner wall of the cylinder are provided with a piston ring 2 to support the piston 8, reduce friction, reduce air leakage, improve thermal efficiency, and make the connection between the piston 8 and the cylinder wall closer.

[0016] Above the middle cylinder 4, there is a high-pressure nitrogen chamber 5 on the side of the reversing valve assembly 3. The high-pressure nitrogen chamber 5 can supplement the air pressure to the piston 8 in the cylinder, so that the pisto...

Abstract

The invention discloses a crushing hammer of a hydraulic machine, which comprises a medium cylinder body, a front cylinder body, a rear nitrogen chamber, a reversing valve assembly and a piston, wherein the medium cylinder body and the front cylinder body are connected into a whole; the rear nitrogen chamber is arranged at the tail end of the medium cylinder body; the reversing valve assembly is arranged above the medium cylinder body; the piston is in the inner cavities of the medium cylinder body and the front cylinder body; and a hammer is connected to the front end of the piston. Piston rings having the effects of supporting the piston, sealing and reducing friction are arranged on the inner walls of the piston and the cylinder bodies; a high-pressure nitrogen chamber is arranged above the medium cylinder body and near the reversing valve assembly; and air pressure can be supplied to the piston in the cylinder body through the high-pressure nitrogen chamber. The crushing hammer of the hydraulic machine disclosed by the invention transmits power through hydraulic pressure and has the advantages of being high in force, rapider for crushing ore and high in working efficiency.

Description

technical field [0001] The invention relates to the field of hydraulic machines, in particular to hydraulic machine breaking hammers. Background technique [0002] The coarse crushing of the ore mined in the existing mines mostly adopts a crusher, and the commonly used one is a rotary hydraulic crusher. The hydraulic press is used to apply pressure to the melt, so that the melt rheological feeding and solidification molding. There are many types of crushing hammers, some of which are rotary mechanical crushers, which rely on mechanical power, have little crushing power, consume electricity, and are expensive. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the present invention provides a hydraulic breaker, which transmits power through hydraulic pressure, and the force of the breaker is large, and the ore is broken faster and the work efficiency is high. [0004] In order to achieve the above object, the technical sc...
