1. How to install the excavator breaker
1. First, we need to remove the pin bushing on the bucket and set it aside for later use.
2. Use a grease gun to inject butter into the drill rod hole sleeve of the hydraulic breaker, install the drill rod, and nail the latch.
3. Put the front cover of the excavator forearm between the ear plates of the hydraulic breaker shell, install the pin sleeve, operate the excavator forearm, lift the breaker hammer, and lower the forearm “cow” Bone” and install the other part of the pin bushing.
4. Use two high-pressure hoses to connect the hydraulic oil pipe on the forearm and the middle cylinder of the hydraulic breaker. Tighten the bolts and open the valve of the hydraulic oil pipe on the forearm. The installation is complete. Test machine.
5. Since most excavators have reserved oil port joints for accessories when they leave the factory, when installing the breaker, you only need to connect the pipelines, joints and Just connect the breaker hammers together.
2. What are the precautions for operating the excavator breaker
1. Every time you use it, you should first check whether the high-pressure or low-pressure oil pipe of the breaker is There is looseness. At the same time, for the sake of caution, you should always check whether there are oil leaks in other places to avoid the oil pipe falling off due to vibration and causing failure.
2. When the breaker is operating, the drill rod should always remain perpendicular to the surface of the object to be broken. And make the drill rod press the broken object tightly. After crushing, the breaker hammer should be stopped immediately to prevent empty hitting. Continuous aimless impact will cause damage to the front body of the breaker and loosening of the main body bolts. In severe cases, the main engine itself may be injured.
3. When carrying out crushing operations, do not use the rocking drill rod, otherwise the main bolt and the drill rod may break; do not let the breaker drop quickly or hit hard rocks hard. This may damage the breaker or main unit due to excessive impact.
4. Do not carry out crushing operations in water or mud. Except for the drill rod, other parts of the breaker body should not be immersed in water or mud, otherwise the piston and other parts with similar functions on it should not be immersed in water or mud. Mud accumulation on parts can cause premature wear of the breaker.
5. When breaking a particularly hard object, you should start from the edge first, and do not hit the same point continuously for more than 1 minute to prevent the drill rod from burning or the hydraulic oil from overheating.
6. Do not use the guard plate of the breaker hammer as a tool to push heavy objects. Since backhoe loaders are mainly small machines and are light in weight, if they are used to push heavy objects, they may be damaged or broken. If the hammer is too heavy, it may cause the boom of the main engine to break, or even cause the main engine to roll over.
Do not perform operations when the hydraulic cylinder is fully extended or fully retracted, otherwise the impact vibration will be transmitted to the hydraulic cylinder body and thus to the host machine.
7. Since the working conditions of the breaker hammer are very harsh, correct maintenance can reduce machine failures and extend the service life of the machine. In addition to timely maintenance of the host machine, the following points should also be paid attention to:
p>
(1) Appearance inspection
Check whether the relevant bolts are loose; whether the connecting pins are excessively worn; check whether the clearance between the drill rod and its bushing is normal. If there is oil leakage, it means that the low-pressure oil seal is damaged and should be replaced by a professional.
(2) Lubrication
The lubrication points of the working device should be lubricated before operation and after 2 to 3 hours of continuous operation.
(3) Replace hydraulic oil
The quality of hydraulic oil varies depending on the working environment. A simple way to judge the quality of the oil is Observe the color of the oil quality. When the oil quality deteriorates extremely seriously, the oil should be drained and new oil should be injected after cleaning the oil tank and oil filter.
8. The main body of the breaker is a set of precision components including a hydraulic circulation system. Generally, factories without special equipment are not allowed to disassemble it by themselves, and must be commissioned for maintenance.
