Abstract
The utility model discloses an excavator bucket protective device of an excavator, which includes an excavator bucket protective plate (1) and a toothholder (2) that are plugged-in together, wherein an internal-convex pit is formed on the contacted surface of the toothholder (2) and the excavator bucket protective plate (1). By adopting the structure, the contacted area with the excavator bucket protective plate is reduced, so that the typical casting defects as deformation and swelling caused by big plane is effectively removed, the better attachment with the plane of the excavator bucket protective plate is realized, the connection between the excavator bucket protective plate and the toothholder becomes firm, and the normal working state of the excavator is ensured.
Description
Technical field
The utility model relates to the plant equipment field, specifically is a kind of excavator bucket guard plate apparatus.
Background technology
Excavator generally is that the engineering machinery that is used to excavate engineerings such as mine, road is used car, and the bucket backplate is one of them component on the excavator.The bucket backplate of prior art normally is connected with excavator-type shovel clamshell excavator through toothholder, and an end of bucket backplate has the inclined-plane, and the bucket backplate is plugged on toothholder through this inclined-plane.But, the problem below the bucket guard plate apparatus of this structure exists: because the inclined-plane is to realize through being adjacent to of face and face with cooperating of toothholder, in other words; The cooperation place of toothholder and bucket backplate is made up of two crossing planes, i.e. lower plane and ramp, like this; The lower plane of the lower plane of toothholder and bucket backplate is adjacent to, and the inclined-plane of the ramp of toothholder and bucket backplate is adjacent to, therefore; When being adjacent to face face to face, contact surface is bigger, and just correspondingly the requirement of the flatness on opposite is high more, because toothholder is formed by casting; The plane is bigger just to be easy to generate casting flaws such as distortion, bulge more, and when the plane irregular place is arranged slightly, will produce and the jiggly phenomenon of another plane contact; Therefore; The bucket backplate is connected not steady with toothholder, the bucket backplate will be thrown off from toothholder, thereby influences the duty of whole bucket.
The utility model content
The utility model technical problem to be solved is to provide a kind of bucket backplate that can make to be connected firmly with toothholder, thereby guarantee the excavator bucket guard plate apparatus of bucket normal operating conditions.
For solving the problems of the technologies described above, the excavator bucket guard plate apparatus that the utility model provides comprises the bucket backplate and the toothholder that are plugged on together, the pit that has indent on the contact plane of described toothholder and bucket backplate.
One end of described bucket backplate has the inclined-plane, and correspondingly the junction of toothholder and bucket backplate is made up of lower plane and ramp.
Have on the lower plane of described toothholder along the following pit of the edge indent of lower plane, have on the ramp along the last pit of the edge indent of lower inclined plane.
After adopting above structure, the utility model with compared with techniques is arranged, have the following advantages: owing to all have along the pit of horizontal edge indent on the lower plane that combines with the bucket backplate of toothholder and the ramp; Like this; Reduced the contact area with the bucket backplate, eliminated effectively because typical casting flaws such as the big distortion that causes in plane, bulges, also fitted with the plane of bucket backplate better; Thereby the bucket backplate is connected firmly with toothholder, has guaranteed the normal operating conditions of bucket.

The utility model: 1, bucket backplate; 1.1, the inclined-plane; 2, toothholder; 2.1, lower plane; 2.2, ramp; 2.3, following pit; 2.4, go up pit.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation in further detail.
Structural representation by toothholder in the excavator bucket guard plate apparatus of prior art illustrated in figures 1 and 2 can be known; It comprises the toothholder 2 ' that matches with bucket backplate 1 '; Have inclined-plane 1.1 ' on the bucket backplate 1 ', have the ramp 2.2 ' and lower plane 2.1 ' that match and be connected with the inclined-plane 1.1 ' and the bottom surface of bucket backplate 1 ' on the toothholder 2 '.
Structural representation by Fig. 1, Fig. 3 and the utility model excavator bucket guard plate apparatus shown in Figure 4 can know that it comprises the bucket backplate 1 and toothholder 2 that is plugged on together, the pit that has indent on the contact plane of described toothholder 2 and bucket backplate 1.
One end of described bucket backplate 1 has inclined-plane 1.1, and correspondingly toothholder 2 is made up of lower plane 2.1 and ramp 2.2 with the junction of bucket backplate 1.Have on the lower plane 2.1 of described toothholder 2 along the following pit 2.3 of the edge indent of lower plane, have on the ramp 2.2 along the last pit 2.4 of the edge indent of lower inclined plane.
Claims (3)
1. an excavator bucket guard plate apparatus comprises the bucket backplate (1) and the toothholder (2) that are plugged on together, it is characterized in that: the pit that has indent on the contact plane of described toothholder (2) and bucket backplate (1).
