Abstract
The utility model discloses a bucket tooth structure for engineering machines, and belongs to the technical field of engineering machine equipment. The bucket tooth structure comprises bucket tooth and further comprises a metal protecting sleeve and fixing screws. A plurality of bolt holes are evenly distributed in the periphery of the front end of the bucket tooth. The metal protecting sleeve corresponds to the appearance of the front end of the bucket tooth and is arranged at the front end of the bucket tooth, a plurality of round holes corresponding to the bolt holes evenly distributed around the front end of the bucket tooth are formed in the periphery of the metal protecting sleeve, and the metal protecting sleeve is fixedly arranged at the front end of the bucket tooth through the fixing screws. A plurality of grooves are formed in the front end of the metal protecting sleeve in parallel, and the distance between every two adjacent grooves is 5 cm to 8 cm. The metal protecting sleeve is arranged at the front end of the bucket tooth and is fixed through the screws. When the metal protecting sleeve is abraded, it is not required to replace the whole bucket tooth, only the metal protecting sleeve needs to be replaced, and therefore cost is saved. Meanwhile, the grooves are formed in the front end of the metal protecting sleeve in parallel, the distance between every two adjacent grooves is 5 cm to 8 cm, the certain protecting and buffering function is achieved, and normal use and work efficiency are ensured.
Description
Technical field
The utility model relates to a kind of bucket tooth, and specifically a kind of engineering machinery Tooth structure, belongs to engineering mechanical device technical field.
Background technology
Excavator and loader are widely used in digging, civil engineering, water conservancy and defence construction, in its course of work, bucket tooth is the parts that directly contact with rock, ore or soil, very severe because of operating mode, also has higher impact resistance when requiring it to have high-wearing feature.
At present, the main method that improves bucket tooth abrasion resistance has: optimize bucket tooth casting technique and Technology for Heating Processing, interpolation trace alloying element etc., these methods are to preventing the wearing and tearing of bucket tooth, played certain effect, but limited for the material quality of using, but still can not meet Production requirement, and waste time and energy while changing, waste time and efficiency in use, and due to needs integral replacing, increased cost.
Summary of the invention
For the problems referred to above, the utility model provides a kind of engineering machinery Tooth structure, simple in structure, and it is convenient to change, and when guaranteeing to use, reduces costs.
For achieving the above object, the utility model comprises bucket tooth, also comprises protective metal shell and fixed screw; The uniform a plurality of bolts hole of surrounding of bucket tooth front end; The profile of the front end of the corresponding bucket tooth of protective metal shell, and be arranged on the front end of bucket tooth, the uniform a plurality of bolts hole of surrounding of the corresponding bucket tooth front end of surrounding have a plurality of circular holes, and by fixed screw, are fixed on the front end of bucket tooth; The front end of protective metal shell has a plurality of grooves side by side, and each groove distance is 5-8cm.
Further, protective metal shell is stainless steel sheath.
Further, between protective metal shell and bucket tooth front end, be provided with one deck cushion coat, cushion coat is rubber layer or the hard plastic bed of material.
Further, the upper and lower surface of protective metal shell front end and two sides are evenly equipped with several PDC.
Further, the PDC putting at the right-angle side place of protective metal shell front end upper and lower surface and two sides is half sheet or quarter-wave plate, and its straight flange is concordant with the right-angle side of bucket tooth.
Further, PDC is composite polycrystal-diamond, and profile is antiparallelogram, and upper surface is diamond layer.
Further, the inner surface surrounding that the front end of protective metal shell has a plurality of grooves is side by side provided with one deck aluminium alloy layer.
Compared with prior art, the utility model is by a protective metal shell is set at bucket tooth front end, and is screwed; When protective metal shell, receive after wearing and tearing, do not need to change whole bucket tooth, only need to change protective metal shell, thereby saved cost; Meanwhile, at protective metal shell front end, have side by side a plurality of grooves, each groove distance 5-8cm, plays certain protection and cushioning effect, has guaranteed normal use and operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, bucket tooth, 2, fixed screw, 3, protective metal shell, 4, PDC, 5, groove.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of engineering machinery Tooth structure, comprises bucket tooth 1, also comprises protective metal shell 3 and fixed screw 2; The uniform a plurality of bolts hole of surrounding of bucket tooth 1 front end; The profile of the front end of the corresponding bucket tooth 1 of protective metal shell 3, and be arranged on the front end of bucket tooth 1, the uniform a plurality of bolts hole of surrounding of corresponding bucket tooth 1 front end of surrounding have a plurality of circular holes, and by fixed screw 2, are fixed on the front end of bucket tooth 1; The front end of protective metal shell 3 has a plurality of grooves 5 side by side, and each groove 5 distance is 5-8cm.
As the preferred mode of the utility model, protective metal shell 3 is stainless steel sheath, guarantees application life.
As the utility model, further improve, between protective metal shell 3 and bucket tooth 1 front end, be provided with one deck cushion coat, cushion coat is rubber layer or the hard plastic bed of material, plays the effect of buffering.
As the utility model, further improve, the upper and lower surface of protective metal shell 3 front ends and two sides are evenly equipped with several PDC4, utilize the intensity of PDC4, improve abrasion resistance.
As the preferred mode of the utility model, the PDC4 putting at the right-angle side place of protective metal shell 3 front end upper and lower surfaces and two sides is half sheet or quarter-wave plate, and its straight flange is concordant with the right-angle side of protective metal shell 3, thereby has saved cost.
As the preferred mode of the utility model, PDC4 is composite polycrystal-diamond, and profile is antiparallelogram, and upper surface is diamond layer, the intensity while improving its use.
As the utility model, further improve, the inner surface surrounding that the front end of protective metal shell 3 has a plurality of grooves 5 is side by side provided with one deck aluminium alloy layer, plays the effect of protection and buffering.
The utility model is by bucket tooth 1 front end, a protective metal shell 3 being set, and it is fixing to pass through screw 2; When protective metal shell 3, receive after wearing and tearing, do not need to change whole bucket tooth 1, only need to change protective metal shell 3, thereby saved cost; Meanwhile, at protective metal shell 3 front ends, have side by side a plurality of grooves 5, each groove 5, apart from 5-8cm, plays certain protection and cushioning effect, has guaranteed normal use and operating efficiency.
