And, because gripping mechanism is not to be closely attached on the arm fully, but fix with vacant state, therefore there are the following problems, that is and, the gripping mechanism of originally installing for the convenience of operating limits the operation of the scraper bowl of the basic operation of carrying out excavator on the contrary.
Following structural problem causes the former of the problems referred to above because promptly, not using under the situation that is installed in the gripping mechanism on the excavator, can't be securely fixed on the arm of excavator.
In addition, when using gripping mechanism, the end of gripping mechanism should engage one another with the fork of scraper bowl, but owing to separate with certain spacing, therefore there is following structural problem, that is,, can cause being transferred body and between scraper bowl and gripping mechanism, rock or landing in clamping and when carrying bigger rock or trees etc.
Summary of the invention
The technical problem to be solved in the present invention, the gripping mechanism that promptly the purpose of this invention is to provide a kind of excavator, in the past the structure that is installed on the gripping mechanism that uses on the excavator is improved, only do not use under the situation of scraper bowl not using gripping mechanism, gripping mechanism is loaded closely connected closing on the arm that is fixed in excavator with folding fully state, thereby make that the operation of scraper bowl is not subjected to the obstruction of gripping mechanism when utilizing scraper bowl to carry out dredge operation.
Another object of the present invention provides a kind of gripping mechanism of excavator, when use is installed on gripping mechanism on the excavator, the end of gripping mechanism is engaged one another with the fork of scraper bowl, thereby prevent in clamping and when carrying bigger rock or trees etc., be transferred body and between scraper bowl and gripping mechanism, rock or landing.
The invention effect
According to aforesaid the present invention, can reach following effect.
First, the structure that is installed on the gripping mechanism that uses on the excavator is improved, only do not use under the situation of scraper bowl device not using gripping mechanism, gripping mechanism is fitted with folding fully state to be fixed on the arm of excavator, thereby make that gripping mechanism does not hinder the operation of scraper bowl when utilizing scraper bowl to carry out dredge operation.
The second, when use is installed on gripping mechanism on the excavator, the end of gripping mechanism is engaged one another with the scraper bowl fork, thereby prevent in clamping and when carrying bigger rock or trees etc., be transferred body and between scraper bowl and gripping mechanism, rock or landing.
