Description
Technical field
The utility model relates to excavator, particularly a kind of dredger scraper bowl.
Background technology
Excavator becomes the king of engineering machinery, and it is widely used in various occasion, comprises various bad working environments, such as quarry etc.The scraper bowl of excavator is made up of back side panel, two side shields and the base plate between two side shields, for the ease of maintain and replace teeth, current teeth generally dismantles the leading section being arranged at base plate mutually, usually, the rear portion of teeth has U-shaped draw-in groove, pan front is blocked by U-shaped draw-in groove, then pass through screw-driving, but excavator is under intensive work, teeth is stressed comparatively large, when its left and right sides unbalance stress, screw is stressed larger, when exceeding the holding capacity of screw, screw can get loose and even rupture, thus the phenomenon causing teeth to get loose.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides a kind of dredger scraper bowl, and teeth is installed and firmly not easily got loose.
The technical scheme that the utility model adopts is such: dredger scraper bowl, comprise bucket body and teeth, described bucket body is by back side panel, both sides side shield and base plate enclose and form, the front portion of described base plate is provided with some field joints be arranged in parallel, the rear portion of described teeth has the installation cavity matched with described field joint, the front portion of described teeth forms crown, upper surface and the soffit of described field joint all offer detent, the bar shaped positioning convex matched with described detent is provided with in described installation cavity, the length direction of described detent extends along fore-and-aft direction, described teeth and described field joint are connected by screw.
Further improvement: the upper surface of described teeth and soffit are provided with some helical cut muscle.
Further improvement: the inner side of described base plate is provided with some outwardly arc buffering gussets, and described buffering gusset extends along fore-and-aft direction.
By adopting preceding solution, the beneficial effects of the utility model are: teeth is sheathed in field joint and passes through screw fastening, detent in field joint and the positioning convex in installation cavity match, and excavator teeth under intensive work can be avoided to get loose.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram (not installing teeth);
Fig. 2 is the utility model schematic diagram (being provided with teeth).
Wherein: 1, back side panel; 2, side shield; 3, base plate; 4, teeth; 5, field joint; 6, detent; 7, helical cut muscle; 8, gusset is cushioned.
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Fig. 2, the utility model discloses a kind of dredger scraper bowl, comprise bucket body and teeth 4, described bucket body is by back side panel 1, both sides side shield 2 and base plate 3 enclose and form, the front portion of described base plate 3 is provided with some field joints 5 be arranged in parallel, the rear portion of described teeth 4 has the installation cavity matched with described field joint 5, the front portion of described teeth 4 forms crown, upper surface and the soffit of described field joint 5 all offer detent 6, the bar shaped positioning convex matched with described detent 6 is provided with in described installation cavity, the length direction of described detent 6 extends along fore-and-aft direction, described teeth 4 is connected by screw with described field joint 5.
Operating principle: teeth 4 is fixed by screw after being sheathed on field joint 5, positioning convex now in teeth 4 installation cavity inserts in the detent 6 of field joint 5, because detent 6 extends along fore-and-aft direction, then positioning convex and detent 6 play the spacing effect in left and right, alleviate the holding capacity of screw, under intensive work, even if the left and right unbalance stress of teeth 4, screw also can not get loose, and more can not rupture.
As shown in Figure 2, excavate for the ease of excavator, the upper surface of described teeth 4 and soffit are provided with some helical cut muscle 7, teeth 4 arranges helical cut muscle 7, make excavator when excavating, teeth 4 produces cross shear in the process moved downward, and is convenient to excavate.
As shown in Figure 1 and Figure 2; in order to available protecting scraper bowl is not broken by hard stone; the inner side of described base plate 3 is provided with some outwardly arc buffering gussets 8; described buffering gusset 8 extends along fore-and-aft direction; when running into the hard stone of bulk in excavator mining process and entering scraper bowl; buffering gusset 8 can play the effect of buffering, reduces the shock of hard stone and scraper bowl inwall, thus protection scraper bowl is not crashed through.
More than show and describe general principle of the present utility model and principal character and advantage thereof; the technician of the industry should understand; the utility model is not restricted to the described embodiments; above-described embodiment just illustrates principle of the present utility model with description in explanation; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
