Abstract
A kind of excavator bucket tooth, including the installation portion that may be installed on power shovel, and the work portion being connected with installation portion, described work portion is made up of the flank of the crown of front end, connection crown, described flank is arc, is wherein provided with, in the indent one side of arc flank, the bar-shaped trough that at least one trend is consistent with flank axis.Use excavator bucket tooth described in the utility model, utilize the inner concave at arc flank that bar-shaped trough is set, can be when bucket tooth extruding work soil layer, moisture in soil and fine particle are extruded and discharged from bar-shaped trough, avoid Soil adhesion at bucket tooth inner concave, thus decrease excavating resistance and to the abrasion of bucket tooth and corrosion.
Description
Technical field
This utility model belongs to mechanical field, relates to a kind of excavator parts, is specifically related to a kind of excavator bucket tooth.
Background technology
Excavator bucket teeth is the important easy consumption parts on excavator, is similar to the tooth of people, is made up of toothholder and crown
Dipper Teeth.Excavator bucket teeth is the fastest parts that wear and tear in use, when carrying out dredge operation when soil moisture content
Gao Shi, extruding when excavator inserts causes soil layer to be close to excavator bucket tooth surface, not only causes excavating resistance to increase, and
Make in work process the abrasion of bucket tooth and corrosion-damaged all can increase.
Utility model content
For overcoming existing excavator bucket tooth to be easily adhered clay when the soil layer that moisture is high carries out operation, resistance increases
The technological deficiency that big and erosion corrosion is strengthened, the utility model discloses a kind of excavator bucket tooth.
Excavator bucket tooth described in the utility model, including the installation portion that may be installed on power shovel, and with peace
The work portion that dress portion connects, it is characterised in that described work portion is made up of the flank of the crown of front end, connection crown, described tooth
Abdomen is arc, is wherein provided with, in the indent one side of arc flank, the bar-shaped trough that at least one trend is consistent with flank axis.
Preferably, the cross section of described bar-shaped trough is del, and the both sides of inverted triangle are the arc to bar-shaped trough inner bulge
Line.
Preferably, being provided with three parallel bar-shaped troughs in the indent one side of described flank, middle part bar shaped slot length is longer than
Both sides bar-shaped trough, both sides bar-shaped trough is 1-5 degree with the angle of middle part bar-shaped trough.
Preferably, described work portion end and installation portion are provided with bolt hole, and described work portion passes through with installation portion
Bolt connects.
Preferably, both sides, described work portion are provided with curve slope.
Use excavator bucket tooth described in the utility model, utilize the inner concave at arc flank that bar-shaped trough is set, can
With when bucket tooth extruding work soil layer, the moisture in soil and fine particle are extruded and discharged from bar-shaped trough, it is to avoid soil sticks
It is attached to bucket tooth inner concave, thus decreases excavating resistance and to the abrasion of bucket tooth and corrosion.
Accompanying drawing explanation
Fig. 1 is a kind of detailed description of the invention structural representation of excavator bucket tooth described in the utility model, accompanying drawing in figure
Token name is referred to as 1-installation portion, 2-work portion, 3-bolt hole, 4-crown, bar-shaped trough in the middle part of 5-, 6-both sides bar-shaped trough, 7-arc
Shape inclined-plane.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in further detail.
Excavator bucket tooth described in the utility model, including the installation portion 1 that may be installed on power shovel, and with peace
The work portion 2 that dress portion connects, described work portion is made up of the flank of the crown 4 of front end, connection crown, and described flank is arc,
Wherein it is provided with, in the indent one side of arc flank, the bar-shaped trough that at least one trend is consistent with flank axis.
This utility model utilizes and arranges bar-shaped trough at the inner concave of arc flank, can when bucket tooth extruding work soil layer,
Moisture in soil and fine particle are extruded and discharged from bar-shaped trough, it is to avoid Soil adhesion is at bucket tooth inner concave, thus reduces
Excavating resistance and to the abrasion of bucket tooth and corrosion.
For snapping in sandstone foreign body in avoiding bar-shaped trough, the cross section of described bar-shaped trough is preferably arranged to del, inverted triangle
Both sides be the camber line to bar-shaped trough inner bulge, two sides of convex make reduced space in bar-shaped trough, are difficult to snap in different
Thing.
As it is shown in figure 1, in the detailed description of the invention shown in Fig. 1, be provided with in the indent one side of flank three parallel
Bar-shaped trough, middle part bar-shaped trough 5 length is longer than both sides bar-shaped trough 6, and both sides bar-shaped trough 6 is 1-5 degree with the angle of middle part bar-shaped trough 5.
Use multiple bar-shaped trough to tackle wider work surface and the bigger soil layer of moisture, the angle of both sides bar-shaped trough arrange be by
The direction of motion in bucket tooth axis both sides is not parallel with axis, and the both sides bar-shaped trough of inclination more meets actual loading during operation
Situation, the space being simultaneously obliquely installed between the bar-shaped trough that both sides bar-shaped trough also makes is gradually increased, and can reduce soil layer resistance.
Another kind of preferred implementation, for arranging curve slope 7 in both sides, work portion, reduces both sides when excavating further
Resistance.
Previously described for each preferred embodiment of the present utility model, the preferred implementation in each preferred embodiment
If not the most contradictory or premised on a certain preferred implementation, each preferred implementation can arbitrarily superposition
Being applied in combination, the design parameter in described embodiment and embodiment is merely to clearly state the utility model of utility model people
Proof procedure, and be not used to limit scope of patent protection of the present utility model, scope of patent protection of the present utility model still with
Its claims are as the criterion, the equivalent structure change that every utilization description of the present utility model and accompanying drawing content are made, in like manner
Should be included in protection domain of the present utility model.
