Abstract
The utility model discloses an excavator shovel tooth and relates to the technical field of mechanical accessories. The excavator shovel tooth comprises a shovel tooth and a shovel tooth fixing base. A pin hole is formed in the middle of the shovel tooth, the front of the shovel tooth is in a cambered structure, and the shovel tooth and the shovel tooth fixing base are in an integrated structure. A notch is formed in the shovel tooth fixing base, the shovel tooth is mounted on an excavator bucket through the notch, a shovel tooth protection plate is arranged on the outer side of the shovel tooth and is connected with the pin hole in the shovel tooth through a hinge pin to cover the shovel tooth tightly, and the end of the shovel tooth protection plate is connected onto the shovel tooth fixing base through bolts. The excavator shovel tooth is simple in structure, novel in design, high in integral strength, good in abrasion resistance and capable of prolonging the shovel tooth service life and reducing the production cost.
Description
Technical field
The utility model relates to mechanical fitting technical field, is specifically related to a kind of excavator shovel tooth.
Background technology
Excavator is indispensable plant equipment in various engineering constructions, and the teeth of excavator is subject to continuous wearing and tearing in construction, need to change in time.In order to reduce the cost, reduce the part of changing, the teeth of a lot of excavators is designed to two body structures, teeth is combined by teeth holder and spear, spear wearing and tearing are at work much larger than teeth holder, only need to change as a rule spear, the teeth holder long period just needs to change, and has reduced cost.In the middle of the teeth holder of this double-body bike teeth is thick by two with spear, thin pin is connected, and an elastic ring is installed in the middle of pin, and two parts are combined as a resilient key and used.During installation, first spear and teeth holder are installed together, then resilient key is squeezed in pin-and-hole.In use, along with the wearing and tearing of teeth, the stressed continuous increase of pin, causes pin to become curved, dismantles very difficult.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, anti abrasive excavator shovel tooth.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of excavator shovel tooth, comprise teeth and teeth holder, in the middle of described teeth, be provided with a pin-and-hole, described teeth front portion is arc-shaped structure, described teeth holder and teeth are structure as a whole, on described teeth holder, be provided with a notch, by this notch, teeth is installed on bucket, described teeth outside is provided with teeth backplate, this teeth backplate is connected with the pin-and-hole on teeth by bearing pin, described teeth is closely wrapped, and described teeth backplate end is bolted on teeth holder.
The Length Ratio of described teeth holder and teeth is 20:9, makes teeth stressed evenly.
Between the top and the bottom of described teeth one end and base, all leave one section of support portion, object is to improve the intensity of teeth holder.
The rear portion indentation of described notch, can be good at being connected with bucket, can not produce obscission.
The beneficial effects of the utility model are: the utility model is simple in structure, modern design, and bulk strength is high, and abrasion resistance is good, can extend the application life of teeth, reduces production costs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of excavator shovel tooth, comprise teeth 1 and teeth holder 2, in the middle of teeth 1, be provided with a pin-and-hole 3, teeth 1 front portion is arc-shaped structure, teeth holder 2 is structure as a whole with teeth 1, on teeth holder 2, be provided with a notch 4, by this notch 4, teeth 1 is installed on bucket, teeth 1 outside is provided with teeth backplate 5, this teeth backplate 5 is connected with the pin-and-hole 3 on teeth 1 by bearing pin, and teeth 1 is closely wrapped, and teeth backplate 5 ends are bolted on teeth holder 2.Teeth holder 2 is 20:9 with the Length Ratio of teeth 1, makes teeth 1 stressed evenly.Between the top and the bottom of teeth 1 one end and base, leave one section of support portion 6, object is to improve the intensity of teeth holder 2, and the rear portion zigzag of notch 4, can be good at being connected with bucket, can not produce obscission.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
