Problems solved by technology

[0002] As we all know, when the excavator is digging, the bucket will easily bring sediment and other particles into the pin shaft of the bucket when the bucket is turned, and the butter in the bucket will be gradually squeezed out of the pin shaft, so that the pin shaft and the bushing, tooling Parts such as the word frame and bucket connecting rod rub against each other with particles, which intensifies the wear of other parts such as the pin shaft and shortens the service life; the wear of other parts such as the pin shaft leads to greater mechanical vibration and noise large, which has a serious impact on the operator's body; the operator needs to apply butter to the pin shaft many times to relieve the wear of other parts such as the pin shaft, which greatly increases the workload of the operator and causes a waste of resources
[0003] The bucket oil seal of the excavator is most likely to be damaged, because the working surface in the bucket oil seal is close, and the mud will splash on the first hydraulic lever of the bucket when the bucket is excavated. Due to the needs of the operation of the excavator, sometimes the first hydraulic lever of the bucket The end is not fully retracted into the oil cylinder oil seal. After the excavator works, the temperature will become high, and the mud will solidify soon. When the solidified mud is cleaned, the oil seal will easily be damaged, resulting in hydraulic oil leakage.

Abstract

The invention relates to a mechanical arm and an excavator with the same. The mechanical arm comprises a protective device, a bucket, a mechanical arm body and a first hydraulic rod. One end of the mechanical arm body is connected with one end of the bucket; one end of the first hydraulic rod is connected with one end of the bucket; the other end of the first hydraulic rod is connected with the other end of the mechanical arm body; and the protective device is installed on the bucket. The mechanical arm and the excavator with the same have the beneficial effects that the protective device is installed on the bucket, so that particulate matters are effectively blocked and prevented from entering a pin shaft, abrasion to other parts such as the bucket, an oil cylinder, the mechanical arm body and the pin shaft is reduced, and the service life is prolonged; noise generated during usage of the excavator is lowered; the working strength of operators is relieved; and the effective utilization ratio of resources is increased.

Description

technical field [0001] The present invention relates to the technical field of excavation, in particular to an excavator, in particular to a mechanical arm and an excavator including the mechanical arm. Background technique [0002] As we all know, when the excavator is digging, the bucket will easily bring sediment and other particles into the pin shaft of the bucket when the bucket is turned, and the butter in the bucket will be gradually squeezed out of the pin shaft, so that the pin shaft and the bushing, tooling Parts such as the word frame and bucket connecting rod rub against each other with particles, which intensifies the wear of other parts such as the pin shaft and shortens the service life; the wear of other parts such as the pin shaft leads to greater mechanical vibration and noise Large, it has a serious impact on the operator's body; the operator needs to apply butter to the pin shaft many times to alleviate the wear of other parts such as the pin shaft, which...
