Gravity crushing hammer and automatic control method

Abstract

The invention discloses a gravity type breaker and a control method thereof. The gravity type breaker comprises: a cylinder body; a drill rod; a hammer block; a piston cylinder including a cylinder barrel and a piston rod fixedly connected with the hammer block; a drive pump; a fluid pipe The road is connected between the driving pump and the piston cylinder; the control valve assembly is arranged on the fluid pipeline; the first detection device is used to detect whether the hammer reaches the first position on the cylinder during the upward movement of the hammer; The control device is signal-connected with the control valve assembly and the first detection device, and includes a timing device. The control device is configured to: when the first detection device detects that the hammer block reaches the first position during the upward movement of the hammer block, the control device controls After the first time, the valve assembly cuts off the communication between the drive pump and the piston cylinder so that the hammer continues to move upward under the action of inertia, and after the second time passes after the connection between the drive pump and the piston cylinder is cut off, the control The device controls the control valve assembly to actuate the hammer block to start moving down.

Description

technical field [0001] The invention relates to the field of crushing operations, in particular to a gravity type breaking hammer and an automatic control method thereof. Background technique [0002] The breaker is installed on excavators and loaders. It is used to break stones, rocks, concrete slabs, etc., and plays an important role in many fields such as mineral mining and civil construction. Most of the existing breakers are hydraulic breakers, which are broken by hammering the drill rod through the hammer head of the piston rod. , the drill rod can be kept horizontal for horizontal crushing, or the drill rod can be kept vertical for vertical crushing. And in the rock crushing operation, it is mainly controlled by foot and manual, and the degree of automation is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a gravity type breaker and an automatic control method thereof, which have good crushing effect and high degree of au...

AI Technical Summary

Problems solved by technology

Most of the existing breaking hammers are hydraulic breaking hammers. The hammer head of the piston rod is used to beat the drill rod for crushing. The hammer head of the hydraulic breaking hammer is lighter in weight, and the power for hammering the drill rod mainly comes from hydraulic oil. , the chisel can be kept horizontal for horizontal crushing, or the chisel can be kept vertical for vertical crushing, the use scene is more flexible, but the hammering force is not strong enough

And in the rock crushing operation, it is mainly controlled by foot and manual, and the degree of automation is low.
