Mountain-cutting heavy punch

Abstract

The invention discloses a mountain-cutting heavy punch. A through hole is formed in the bottom wall of a barrel body; a guide sleeve is arranged in the through hole in a penetrating mode; a brazing rod is arranged in the guide sleeve in a sleeved mode; a punch body, a slide path, a first oil cylinder and a nitrogen gas chamber are arranged in the barrel body; the upper part of the punch body is connected with a piston rod of the first oil cylinder; a cylinder barrel of the first oil cylinder communicates with a nitrogen gas chamber; the brazing rod comprises a rod body and a rod head; and therod body is connected with the rod head through a pin roll. The mountain-cutting heavy punch has the advantages that: compared with a conventional crushing hammier, dropping speed is extremely high after the punch body is lifted and bears dual action of self-gravity and pushing force of compressed nitrogen gas in the nitrogen gas chamber, hitting force on the brazing rod by the punch body is great, crushing force is increased and crushing efficiency is improved; the rod body of the brazing rod and the rod head of the brazing rod can be freely dismounted, and can be independently replaced afterthe rod head is worn, so that cost is reduced, and working efficiency is improved; and a rake can be used for clearing broken stones or other garbage, so that the integral environment is guaranteed to be beneficial for crushing work. The mountain-cutting heavy punch is clean in operation, is free of waste gas emission, is simple to maintain, and is low in fault rate.

Description

technical field [0001] The invention belongs to the technical field of manufacturing crushing equipment for mines, tunnels and construction machinery, and in particular relates to a mountain-breaking hammer. Background technique [0002] At present, in various mining, tunnel excavation, and construction projects, crushing equipment is often used as an indispensable additional tool for excavators, mobile loaders, and backhoe loaders. The hydraulic crusher commonly used in the prior art works in the process of digging rocks, breaking ice and crushing concrete, etc., its working principle is as follows: the hydraulic oil is distributed to the front and rear chambers of the hammer cylinder through the control valve, so that the hammer body reciprocates and impacts the broken drill. The tail of the rod makes the head of the drill rod gradually penetrate into rocks, ice, concrete, etc., breaking them into small pieces. The existing hydraulic crusher has the following disadvantage...

AI Technical Summary

Problems solved by technology

The existing hydraulic crusher has the following disadvantages: the hammer body of the crusher is small in weight, and it mainly relies on hydraulic oil to drive and its free fall motion to strike the chisel rod, which has limited strength and is not easy to break for larger, high-hardness stones, etc.; The drill rod and its drill rod head are an integrated structure, and the drill rod head is easily damaged, resulting in the replacement of the drill rod as a whole, and the cost is too high
