Embodiment Construction

[0014] The specific implementation will be described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the excavator bucket includes a left side plate, a right side plate and a bucket bottom between the left side plate and the right side plate. Such as figure 2 As shown, the front part of the bucket bottom is a flat plate 7, a back plate 6 at the rear, and an arc connecting portion 4 between the flat plate 7 and the back plate 6. The flat plate 7 is horizontal and connected by an arc The curvature of the arc at the front end of the part 4 is small, but the curvature of the arc becomes larger as it goes to the rear. The back plate part 6 is provided with an ear plate 5, which is used to connect the bucket with the excavator arm and connecting rod. The front part of the flat part 7 The edge is provided with a main knife plate 1, and the bottom of the bucket is composed of two layers of plates at its circular arc joint 4. The inner layer ...

Abstract

The invention relates to an excavator bucket and aims to solve the problem of conflict between the excavating efficiency and the land leveling efficiency of an existing excavator bucket. The excavator bucket disclosed by the invention comprises a left side plate, a right side plate and a bucket bottom, wherein a flat plate part is arranged in the front of the bucket bottom, a back plate part is arranged at the back of the bucket bottom, and a circular arc connecting part is arranged in the middle of the bucket bottom; a main knife plate is arranged at the front edge of the flat plate part; at least one longitudinal strip-shaped land leveling rib is arranged on the bottom surface of the bucket bottom in a welding way; the front end of the land leveling rib is butted with the main knife plate, and the rear end of the land leveling rib is lapped on the circular arc connecting part of the bucket bottom; the bottom surface edge of the land leveling rib is a straight line; the shape of the top surface of the land leveling rib is matched with that of the bottom of the bucket bottom, and the top surface of the land leveling rib is attached to the bucket bottom. Through the land leveling rib, the straight surface in the left-right direction is enlarged, and the leveling efficiency is improved; a land leveling rib plate in the excavation direction is protruded downwards and is resistant to soil, the bucket is guided during excavation, the excavation resistance is lower, the land leveling rib plate can be used as a wear-resistant plate, and the bucket is more wear-resistant.

Description

technical field [0001] The invention relates to a bucket, in particular to an excavator bucket. Background technique [0002] The excavator bucket includes a left side plate, a right side plate and a bucket bottom located between the left side plate and the right side plate. The front end of the bucket is the main knife plate, the rear end of the bucket bottom is the back, and there is an arc connecting part between the back and the flat part. In order to ensure the smoothness of excavation in existing excavator buckets, the flat plate portion at the front end of the bucket bottom is as short as possible when the bucket shape is designed, and the arc connecting portion extends forward as much as possible. However, as the king of construction machinery, the excavator is often faced with various working conditions. For example, the excavator also has the function of leveling the land. The flat plate portion at the bottom of the bucket is used to level the land, and the longe...
