In view of this, the utility model proposes protection structure, the engineering machinery of a kind of scraper bowl and dipper junction O type circle, do not collided with protection O type circle.
For achieving the above object, the technical solution of the utility model is achieved in that
On the one hand, the utility model provides the O type circle protection structure of a kind of scraper bowl and dipper junction, and this O type circle protection structure comprises: be used for placing the groove of O type circle, be opened in the position of O type circle to be laid on scraper bowl Connection Block seat board.
Further, in said apparatus, the O type circle of described scraper bowl and dipper junction protection structure also comprises: be used for checking the breach in scraper bowl and gap, dipper junction, be opened in the outer peripheral edges of described groove.
Further, in said apparatus, described breach is at least one.
Further, in said apparatus, described breach is four, is arranged in respectively the groove outer peripheral edges.
Further, in said apparatus, described O type circle protection structure also disposes: for any one digs the hook-shaped part of O type circle from described breach.
On the other hand, the utility model also provides a kind of engineering machinery, and this project machinery is provided with the O type circle protection structure as above-mentioned any described scraper bowl and dipper junction.
Further, in said apparatus, described engineering machinery is excavator.
With respect to prior art, the utlity model has following advantage:
The scraper bowl Connection Block seat board that the utility model will coordinate with O type circle is designed to the form of structure with Baltimore groove, and described groove can be protected O type circle, prevents that O type circle from being collided and the impurity such as silt infiltrates O type circle.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can make up mutually.
Basic thought of the present utility model is: the scraper bowl Connection Block seat board that will coordinate with O type circle is designed to the form of structure with Baltimore groove, O type circle is protected, thereby prevented from being collided and the impurity such as silt infiltrates.
Below in conjunction with accompanying drawing, each preferred embodiment of the present utility model is described further:
As extremely shown in Figure 5 in Fig. 1; the present embodiment provides the O type circle protection structure of a kind of scraper bowl and dipper junction; this O type circle protection structure comprises: be used for placing the groove 21 of O type circle 1, described groove 21 is opened in the position of O type circle 1 to be laid on scraper bowl Connection Block seat board 2.
In a preferred embodiment, the O type circle of described scraper bowl and dipper junction protection structure also comprises: be used for checking the breach 22 in scraper bowl 4 and dipper 3 gaps, junction, described breach 22 is opened in the outer peripheral edges of described groove 21.
Need to prove, in above-described embodiment, described breach 22 is at least one.As shown in Figure 3 and Figure 4, scraper bowl Connection Block seat board 2 is designed to the shape of groove 21, is convenient to place and protection O type circle 1.As Fig. 1 and shown in Figure 5, before dipper 3 and scraper bowl 4 assemblings, O type circle 1 is put between the groove 21 of the anterior cylinder of dipper 1 and scraper bowl Connection Block seat board 2, bearing pin 5 is penetrated in scraper bowl 4, dipper 3 and O type circle pin-and-hole and fixing.
Preferably, in above-described embodiment, described breach 22 is four, is arranged in respectively groove 21 outer peripheral edges.
Like this; in the engineering machinery use procedure with above-mentioned O type circle protection structure; when whether the gap that need to check dipper and scraper bowl connecting portion is suitable; with hook-shaped part from any one 4 breach 22 of scraper bowl Connection Block seat board 2 with O type circle 1 to dipper cylinder one rollover, can check the gap.
Therefore, can find out from the various embodiments described above, the utlity model has following advantage:
The scraper bowl Connection Block seat board that the utility model will coordinate with O type circle is designed to the form of structure with Baltimore groove; described groove can be protected O type circle; prevent that O type circle from being collided; and can prevent that the impurity such as silt from infiltrating in O type circle; lubrication oil is overflowed from dipper cylinder one side take away superincumbent dust, sealing is better.
The utility model embodiment also provides a kind of engineering machinery; excavator for example; this project machinery is provided with the O type circle protection structure of above-mentioned any scraper bowl and dipper junction; because the O type circle protection structure of above-mentioned any scraper bowl and dipper junction has above-mentioned technique effect; therefore; the engineering machinery that is provided with the O type circle protection structure of this scraper bowl and dipper junction also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby give unnecessary details.
