The main factor that determines the length of the excavator scarifier is the installation position and size of the scarifier support angle, which also has a certain impact on the performance of the whole machine. The installation position of the support angle is too close to the vehicle body, which is easy to cause the large soil or stone stripped by the scarifier to be stuck between the support angle and the track, causing damage to the vehicle; If it is too far away from the vehicle body, it is easy to lift the vehicle body off the ground during the process of cornering, reducing the large pressure of the excavator scarifier and the adhesion and traction of the vehicle, and reducing the scarifying performance of the vehicle.
Lifting height of excavator ripper
The lifting height of the excavator scarifier mainly affects the passing ability of the vehicle. Generally speaking, when the support angle of the scarifier is raised to a large height, the departure angle is required to be greater than 20 degrees. The design can be based on that the large lifting height of the scarifier is greater than the small ground clearance of the bulldozer.
Parameter design of support angle of excavator scarifier
The support angle is the main bearing part of the soil loosening operation load. The strength and relevant parameters of the excavator’s single hook scarifier have a great impact on the soil loosening performance of the excavator’s scarifier. However, due to the diversity of its working objects and the complexity of its stress, there is no mature design calculation formula at present, which basically relies on experience for analogy, amplification design, finite element analysis and test verification.
