Problems solved by technology
The above two methods have great certainty. The first one is that the hydraulic cylinder needs to reciprocate for a long time to do the same movement, which will cause the instability of the hydraulic oil circuit and damage other components in the oil circuit. Once it is damaged, it is very inconvenient to replace; the second one Setting it at the end cover will affect the formation of the hydraulic cylinder and cannot achieve the desired working effect

The invention discloses an excavator capable of reducing the impact of cylinders. The excavator is provided with a crawler belt, a rotary platform and a cab, wherein the rotary platform is carried onthe crawler belt, the cab is arranged on the rotary platform, a boom and the boom cylinder used for driving the boom to rotate are arranged on the rotary platform, an arm is arranged at one end of theboom, the arm is driven to rotate through the arm cylinder, a bucket is arranged at one end of the arm, and the bucket is driven to rotate through the bucket cylinder; and the excavator is further provided with a mechanism which enables the boom cylinder, the arm cylinder and the bucket cylinder to perform speed reduction at the operation terminal. According to the excavator capable of reducing the impact of the cylinders, the impact between cylinder pistons and cylinder bottoms and end covers can be effectively reduced, so that the service life of the hydraulic cylinders and the stability ofoil ways are improved.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to an excavator which reduces the impact of an oil cylinder. Background technique [0002] When the hydraulic cylinder drives a working part with a large mass and a fast movement speed, a buffer device is generally required. Its purpose is to eliminate the mechanical impact between the piston and the cylinder head and cylinder bottom caused by the inertial force and hydraulic pressure of moving parts. There are two commonly used methods at present. One is to control the flow of hydraulic oil inside the cylinder. To achieve the purpose of buffering, the other is to set a buffer pad at the end cover. The above two methods have great certainty. The first one is that the hydraulic cylinder needs to reciprocate for a long time to do the same movement, which will cause the instability of the hydraulic oil circuit and damage other components in the oil circuit. Once it is damaged, it...
