Comparison of excavator stump ripper arm and hydraulic breaker

When we carry out the crushing operation, the first thought is to use the breaker. It is undeniable that the breaker plays a very obvious role in mountain cutting, mining, grid crushing, secondary crushing, etc., but its work efficiency and the convenience of maintenance Compared with the broken tool below, it is too far behind, it is the excavator stump ripper arm.

As a new and improved product, the excavator stump ripper arm has taken a higher level in terms of work performance, which greatly meets people's needs. What are the advantages and performance of this device? Let's introduce it in detail below.

The excavator stump ripper arm is a device at the front end of the excavator. Its appearance is extremely like an eagle beak, so it is also called an "eagle beak" arm. This device was originally a modified arm designed for construction work such as weathered rock.

Compared with the breaking hammer, this device has very high working efficiency, low loss and convenient maintenance. Then it is applied to extreme operating environments such as mining and crushing, which greatly meets the needs of the project.

At first, the front end of the first-generation excavator stump ripper arm was equipped with a ripper and bucket cylinder, and the solid arm at the rear end was cast with high-strength manganese steel. There are not only a large number of pit press plates in the arm, but also a mixture of iron sand and cement, which improves the quality, durability and work efficiency of the arm.

With the continuous development of technology, the excavator stump ripper arm has been continuously improved, so there is a new type of integrated rock arm. Compared with the traditional type, the integrated rock arm eliminates the bucket cylinder, and directly connects the forearm and the ripper into an integrated rock arm. After adopting this design, compared with the traditional rock boom, the advantages of the new rock boom are more obvious.

First of all, if the bucket cylinder is eliminated, everyone will think that it lacks movement and flexibility. However, in actual work, the old-fashioned excavator stump ripper arm will be limited by the depth when digging the rock with low hardness due to this structure design, and the ripper is easy to break when digging the rock with high hardness. Therefore, the integrated rock arm using a whole piece of steel plate solves this problem well. At the same time, maintenance is more convenient and the failure rate is lower.

Not only that, after the one-piece excavator stump ripper arm cancels the bucket cylinder, the oil lines of the crude oil cylinder and the stick cylinder are now merged into the pipe of the stick cylinder, which increases the hydraulic oil flow of the stick and greatly improves the rock arm. Power and speed.

In terms of structure, the boom of the new ripper boom no longer adopts a solid structure, but a hollow reinforced boom, which not only reduces the load, but also reduces the overall performance loss of the excavator.
