Description
Technical field
The utility model relates to a kind of tooth cover for excavator, belong to excavator component technology field.
Background technology
The bucket tooth of excavator is parts important on excavator, also be one of parts the most easily consumed, in the work of high strength, bucket tooth is direct and collided by the hard object excavated and rub, thus bucket tooth becomes the consumable accessory of excavator, once certain bucket tooth is damaged, just need whole bucket tooth all will change, add use cost, therefore, usually supporting on bucket tooth have multiple tooth cover, bucket tooth is protected, with by the hard object excavated, as direct contacts such as ores is tooth cover instead of bucket tooth, as long as overlap once impaired tooth is changed in the damage of tooth cover, thus reduction use cost, but existing tooth cover because of unreasonable structure and, the reasons such as raw material are not wear-resisting, so it is short still to there is application life, the technological deficiency such as easy to wear.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, compact, and easy to install and use, wear-resistant, intensity is high, can extend the tooth cover for excavator in excavator application life.
The purpose of this utility model has been come by following technical solution, a kind of tooth cover for excavator, it comprises the block body that a tail end is provided with socket chamber, leading section is provided with taper shovel portion, the fixing intermediate throughholes passing perpendicularly through socket chamber is offered between the rear portion upper and lower surface of this body, the taper shovel portion front end edge of described body offers multiple sintering counterbore, and in it, sintering has hard alloy columnar and forms one with body.
The front end, taper shovel portion of described body be provided with towards upper surface or soffit side be skewed cone angle, wherein become with hard alloy columnar on the jacket surface of side in vertical direction and be provided with two shallow grooves be arranged in parallel, and sintering there is carbide alloy and forms one with body in shallow grooves.
Another of described body is provided with the shallow notch groove in unidirectional with hard alloy columnar, middle dark two on the surface, offer the square shape intermediate throughholes passing perpendicularly through socket chamber between the rear portion upper and lower surface of body, and described through hole is positioned at the centre of notch groove.
The rearward end dual-side of described body offers the arc notch groove being in same center line; Form larger cone angle between the rear portion upper and lower surface of described body, the socket chamber offered in the middle of it is the cone-shaped cavity with the bucket tooth matching form be connected together.
The utility model belongs to the improvement to prior art, and it is simple, compact that it has structure, easy to install and use, wear-resistant, and intensity is high, can extend the features such as excavator application life.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1-3, a kind of tooth cover for excavator described in the utility model, it comprises the block body 3 that a tail end is provided with socket chamber 1, leading section is provided with taper shovel portion 2, the fixing intermediate throughholes 4 passing perpendicularly through socket chamber 1 is offered, for body is fixed on bucket tooth or toothholder between the rear portion upper and lower surface of this body 3.The taper shovel portion front end edge of described body 3 offers multiple sintering counterbore, and in it, sintering has hard alloy columnar 5 and forms one with body 3, and specific embodiment is that multiple sintering counterbore is adjacent uniform successively, can improve hardness and the abrasion resistance of tooth cover.
Shown in figure, it is skewed cone angle that the front end, taper shovel portion 2 of described body 3 is provided with towards upper surface 6 or soffit 7 side, and the embodiment shown in Fig. 1 is towards upper surface 6; Wherein towards side body 3 on the surface with hard alloy columnar 5 one-tenth vertical direction is provided with two shallow grooves be arranged in parallel 8, see shown in Fig. 1,2, and sintering has carbide alloy 9 and is formed integrally with body 3 in shallow grooves 8.The surface easily contacted with hard object in side is embedded hard alloy layer, can improve hardness and the abrasion resistance of tooth cover equally.
Body 3 described in the utility model another on the surface (embodiment in figure is soffit) be provided with the shallow notch groove 10 in unidirectional with hard alloy columnar 5, middle dark two, this notch groove 10 is equivalent to the reinforcing rib adding body, not only reduce the weight of body, also add the intensity of body.Offer the square shape intermediate throughholes 4 passing perpendicularly through socket chamber 1 between the rear portion upper and lower surface of body 3, and described through hole 4 is positioned at the centre of notch groove 10.
The rearward end dual-side of described body 3 offers the arc notch groove 11 being in same center line, the fixed installation of body can be convenient to; Form larger cone angle between the rear portion upper and lower surface 6,7 of described body 3, the socket chamber 1 offered in the middle of it is the cone-shaped cavity with the bucket tooth matching form be connected together.
