Abstract
The utility model provides a wear-resistant excavator bucket tooth which comprises a bucket tooth main body and a protection layer arranged on the outer edge of the bucket tooth main body, wherein a protection cover is arranged at the lower end of the bucket tooth main body; the protection cover is in a grid shape; a protection bump is arranged at the upper end of the bucket tooth main body; the protection bump protrudes outward; reinforcing ribs are arranged on the bucket tooth main body; and the reinforcing ribs are intersected with each other. According to the wear-resistant excavator bucket tooth provided by the utility model, since the protection cover is arranged at the lower end of the bucket tooth main body, the damage of the bucket tooth is effectively reduced, and the wear resistance is improved; due to the protection bump, the bucket tooth is effectively prevented from being damaged by a hard object; and the bucket tooth has a simple structure, long service life and a wide application range.
Description
Technical field
The utility model relates to a kind of excavator accessory, particularly a kind of wear-resisting excavator bucket teeth.
Background technology
Excavator bucket teeth is the vitals on the excavator, it is consumable accessory, the combination bucket tooth of being formed by toothholder and crown, force analysis bucket tooth work plane excavates thing with quilt and contacts, different its stressing conditions difference of working stage in a complete mining process, when the crown position at first contacts the material surface, because speed is very fast, the bucket tooth nose part is subjected to stronger impact, if the intensity of bucket tooth is low, will produce plastic strain in the tip, along with the increasing of excavation depth, the bucket tooth stressing conditions can change to some extent, when bucket tooth cutting material, bucket tooth and material generation relative motion produce very big forward extrusion power on the surface, thereby between bucket tooth work plane and material, produce bigger frictional force, if material is harder rock piece, concrete etc., frictional force will be very big, and the result that this process acts on repeatedly is at bucket tooth work plane generation surface abrasion in various degree, and then produce the bigger ditch dug with a plow of the degree of depth, influence the application life of bucket tooth.
The application life of bucket tooth is very short, changes more frequently, has not only influenced operating efficiency, and wasted great deal of raw materials, and common bucket tooth wears no resistance, and production technology is also relatively poor, the cost height, difficult popularization is in order to increase work efficiency, the bucket tooth that can only usually more renew, increased use cost so greatly, bucket tooth commonly used is short application life, and mining ability is poor, also fracture easily, inefficiency.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of wear-resisting excavator bucket teeth, be arranged on the protective cover of bucket tooth main body lower end, effectively reduce the damage of bucket tooth, improve its anti-wear performance, arranging of protection projection prevents that effectively hard thing from damaging bucket tooth, and this bucket tooth is simple in structure, long service life, applied widely.
The utility model provides a kind of wear-resisting excavator bucket teeth; comprise the bucket tooth main body; be arranged on the topping of described bucket tooth main body outer rim; be provided with protective cover in described bucket tooth main body lower end, described protective cover is latticed, is provided with the protection projection in described bucket tooth main body upper end; described protection projection is to outer lug; be provided with reinforcing rib in the bucket tooth main body, described reinforcing rib is arranged in a crossed manner mutually, and the crosspoint is upper/lower positions in bucket tooth.The purpose of this utility model designs a kind of wear-resisting excavator bucket teeth; be arranged on the protective cover of bucket tooth main body lower end; effectively reduce the damage of bucket tooth; improve its anti-wear performance; arranging of protection projection prevents that effectively hard thing from damaging bucket tooth; this bucket tooth is simple in structure, long service life, applied widely, in the application life that effective protection bucket tooth is set of overcoat, makes it more wear-resistant.
The utility model discloses a kind of a kind of improvement of wear-resisting excavator bucket teeth, the height of described protective cover is 30-60mm.This improvement arranges the height of protective cover, and the excessive height waste material increases cost, the highly too small effect that does not have protection, so the height of protective cover is set to 30-60mm, and the thickness of overcoat is 40mm after tested, and wear-resisting effect is best, and application life is the longest.
The utility model discloses a kind of a kind of improvement of wear-resisting excavator bucket teeth, the thickness of described reinforcing rib is 5-15mm.This improvement arranges the thickness of reinforcing rib, and the excessive waste material of thickness increases cost, the too small effect that does not have protection of thickness, so the thickness of reinforcing rib is set to 5-15mm, and the thickness of reinforcing rib is 10mm after tested, the application life of bucket tooth is better.
The purpose of this utility model designs a kind of wear-resisting excavator bucket teeth; be arranged on the protective cover of bucket tooth main body lower end; effectively reduce the damage of bucket tooth; improve its anti-wear performance; arranging of protection projection prevents that effectively hard thing from damaging bucket tooth; this bucket tooth is simple in structure, long service life, applied widely, in the application life that effective protection bucket tooth is set of overcoat, makes it more wear-resistant.
