Abstract
The utility model discloses a kind of scraper bowl of excavator, comprise scraper bowl body, the lower end edge of described scraper bowl body is provided with can be with respect to the teeth of described scraper bowl body rotation, and described teeth is fixed on described scraper bowl body by adjusting device.Because teeth can rotate with respect to scraper bowl body, teeth can be adjusted angle, and scraper bowl excavates the adaptive capacity enhancing of the cubic metre of earth and stone like this, and digging efficiency improves.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of scraper bowl of excavator.
Background technology
Excavator is widely used in comprising the multiple fields such as mine, urban construction, is bearing the multiple tasks such as mining of earth and stone, and scraper bowl, as the important process parts of excavator, often uses under various severe working environments.In the prior art, the angle of the teeth in scraper bowl is all changeless, and the cubic metre of earth and stone of encountering certain angle just there will be excavation difficulty.
Summary of the invention
The problem that the utility model exists for prior art proposes a kind of scraper bowl of excavator, and object is to improve the adaptive capacity of the scraper bowl excavation cubic metre of earth and stone, improves digging efficiency.
The utility model is achieved in that
A scraper bowl for excavator, is characterized in that, comprises scraper bowl body, and the lower end edge of described scraper bowl body is provided with can be with respect to the teeth of described scraper bowl body rotation, and described teeth is fixed on described scraper bowl body by adjusting device.
In the scraper bowl of above-mentioned a kind of excavator, the lower end edge of described scraper bowl body has bar-shaped trough, is fixed with and the axis of rotation of described bar-shaped trough adaptation on described teeth, and described axis of rotation is embedded in described bar-shaped trough and can in bar-shaped trough, rotates.
In the scraper bowl of above-mentioned a kind of excavator, described adjusting device comprises the fixing hole being positioned on described scraper bowl body, has the adjustment hole that multiple and described fixing hole coordinates on described axis of rotation, and described axis of rotation is bolted on described scraper bowl body.
In the scraper bowl of above-mentioned a kind of excavator, the width of the notch of described bar-shaped trough is less than the diameter of described axis of rotation, and the thickness of described teeth is less than the width of notch.
In the scraper bowl of above-mentioned a kind of excavator, the both ends or one end of described bar-shaped trough have the opening for described axis of rotation turnover.
The scraper bowl of a kind of excavator provided by the utility model, because teeth can rotate with respect to scraper bowl body, teeth can be adjusted angle, and scraper bowl excavates the adaptive capacity enhancing of the cubic metre of earth and stone like this, and digging efficiency improves.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model scraper bowl.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The present embodiment provides a kind of scraper bowl of excavator, as shown in Figure 1, comprises scraper bowl body 100, teeth 200 and adjusting device.Teeth 200 is fixed on scraper bowl body 100 by adjusting device, can regulate the angle of teeth 200 by adjusting adjusting device.
Specifically, teeth 200 is arranged on the lower end edge of scraper bowl body 100, and teeth 200 can rotate with respect to scraper bowl body 100.The lower end edge of scraper bowl body 100 has bar-shaped trough, is fixed with and the axis of rotation 310 of bar-shaped trough adaptation on teeth 200, and axis of rotation 310 is embedded in bar-shaped trough and can in bar-shaped trough, rotates.Wherein, bar-shaped trough and axis of rotation 310 can be segmenteds, can be also whole piece formulas, the present embodiment taking whole piece formula as example.
Adjusting device comprises fixing hole, adjustment hole and bolt 320.Wherein fixed hole position is in scraper bowl body 100, and adjustment hole is arranged on axis of rotation 310, and adjustment hole is provided with multiple and circumferentially distributes along axis of rotation 310, and bolt 320 inserts adjustment hole through fixing hole axis of rotation 310 is fixed on scraper bowl body 100.Bolt 320 is by inserting different adjustment holes to realize the adjusting of teeth 200 angles.
Further, the width of the notch of bar-shaped trough is less than the diameter of described axis of rotation 310.Axis of rotation 310 is embedded in and in bar-shaped trough, can depart from bar-shaped trough like this.The thickness of teeth 200 is less than the width of notch, so just can realize the angle adjustment of teeth 200.The both ends or one end of bar-shaped trough have the opening passing in and out for described axis of rotation 310, and the teeth 200 that so just can change or be replaced with other shapes to the teeth 200 of wearing and tearing is to adapt to the cubic metre of earth and stone of different situations.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or be improved, and all these increases and decreases, replace, conversion or improve after technical scheme, all should belong to the protection domain of the utility model claims.
