By using above-mentioned technical proposal, because bucket tooth and protective case are cast member, cause between protective case and bucket tooth
It is difficult to preferably coordinate, certain gap can be there are；By the setting of rubber layer to being produced between protective case and bucket tooth
Gap play filling effect, rocked caused by reducing protective case in the course of the work.And can be to protecting by the setting of rubber layer
Sheath, which is conducted to the active force of bucket tooth, plays cushioning effect, and reduces the rigid contact between protective case and bucket tooth, to protective case
Certain protective effect is played with bucket tooth.
It is further arranged to：The keeper is the first bolt, and first bolt connects through protective case and bucket tooth screw thread
Connect, the protective case is provided with the groove being embedded for the first bolt head, and the groove is provided with capping.
By using above-mentioned technical proposal, the first bolt is threadedly coupled through protective case and bucket tooth, is protected for realizing
Fixation of the sheath on bucket tooth, and bolt is embedded during rotation into groove, it is used to realize to first by groove
Bolt head houses, then is used to realize the sealing to groove by covering so that medium will not enter inside grooves, convenient
In realizing the separation between protective case and bucket tooth.
It is further arranged to：The scraper bowl plate end face and position between two adjacent bucket tooths is provided with wear-resistant block, institute
State and be fixedly connected between wear-resistant block and protective case by the second bolt.
By using above-mentioned technical proposal, the end face for being located at bucket tooth to scraper bowl plate by the setting of wear-resistant block plays protection
Effect, the scraper bowl abrasion for caused by end face in the course of the work is reduced, further extend the service life of scraper bowl.Pass through second
Bolt is used to realize the fixation between wear-resistant block and protective case so that protective case, can be simultaneously real during being arranged into bucket tooth
Existing wear-resistant block makes the installation between wear-resistant block and protective case more convenient in the fixation of scraper bowl plate end face.
It is further arranged to：The protective case is provided with the stopper slot being embedded for wear-resistant block.
By using above-mentioned technical proposal, wear-resistant block is embedded in stopper slot during installation, is used by stopper slot
In the movement of limitation wear-resistant block so that it is more convenient that the installation of wear-resistant block is fixed.
In summary, the utility model has the advantages that：By being arranged protective case on bucket tooth and by first
The mode of bolt is used to realize fixation of the protective case on bucket tooth, and bucket tooth is played a protective role, extends the service life of scraper bowl
And lift the operating efficiency of scraper bowl；Protective case is arranged to the mode of point and sleeved part and wear-resisting tungsten is set on point
Bisque, on the premise of protective case surplus capacity is lifted, increase the structural strength of point, protective case is played more preferable protection
Effect；By setting extension on the protective sleeve and the depressed part and limit card slot of cooperation extension being set on scraper bowl so that
The active force being subject on protective case can more quickly conduct to scraper bowl plate and reduce the by-local forces being subject on extension, carry
Rise the structural strength of scraper bowl protective case；The position between two bucket tooths is played a protective role by the setting of wear-resistant block, further
Extend the service life of scraper bowl.
