Automatic control system for quartering hammers of crawler type hydraulic excavator

Abstract

The invention provides an automatic control system for quartering hammers of a crawler type hydraulic excavator. The system comprises an electric system, a hydraulic system and an actuating mechanism. The electric system mainly comprises a central controller, a controller area network (CAN) bus, a monitor and a pedal switch. The hydraulic system comprises a main pump, a quartering hammer solenoid valve, a fist ball valve, a second ball valve, an overflow valve and a main valve. The actuating mechanism mainly comprises a quartering hammer. The automatic control system for quartering hammers of the crawler type hydraulic excavator enables a user to simply and conveniently operate and locate to an ideal working state of the quartering hammers. The electric system, the hydraulic system and the actuating mechanism are precisely matched. Accordingly, the whole machine is high in working efficiency and has broad application prospects in an energy saving and environment protection market. In addition, oil consumption is greatly reduced.

Description

technical field [0001] The invention relates to a crawler hydraulic excavator, in particular to an automatic control system for a breaker of the crawler hydraulic excavator and an automatic control mode thereof. [0002] Background technique [0003] Conventional excavator breaker operation is usually controlled by manual adjustment, that is, the operator manually adjusts the throttle to meet the working parameters of the breaker, and then controls the breaker operation through the breaker handle. It is generally recommended that the user keep the throttle at the high-speed position during operation. . However, the problem in the manual adjustment control of the excavator breaker hammer is that it is difficult for the working state of the breaker manual control to meet the parameters, such as working flow, working pressure, impact frequency, etc., and it is often difficult to choose an inappropriate gear during operation , so that its working parameters exceed the range of...

AI Technical Summary

Problems solved by technology

However, the problem in the manual adjustment and control of the excavator breaker hammer is that it is difficult for the manual control of the breaker hammer to meet the parameters, such as working flow, working pressure, impact frequency and other ranges. , so that its working parameters exceed the range of use of the breaker, resulting in a high failure rate of the hydraulic system and structural parts
