Embodiment Construction

[0018] The specific implementation will be described below in conjunction with the accompanying drawings.

[0019] Such as Figure 1 to Figure 7 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. The bucket bottom is usually composed of an inner bottom plate 14 and a reinforcing plate for reinforcement. The front part of the excavator bucket bottom (the front part of the bucket bottom) is usually used for excavation, leveling and other operations, and the back is the bucket connection part, where a shaft seat is set for connection with the arm and connecting rod. The front part and the back of the bucket bottom are arc connecting parts. When the excavator bucket is excavating, the front part of the bucket bottom and the excavated material have relative motion and collision, and there is friction and collision force on the front part of the bucket bottom, while the back of the...

Abstract

The invention relates to an excavator bucket which aims to overcome the defect that an existing bucket is heavy and large in digging resistance. A main cutter board is arranged on the edge of an inner layer plate. A left side plate and a right side plate are provided with a left protection plate and a right protection plate respectively, and the left protection plate and the right protection plate extend from the front ends of the respective bottoms to the left end and the right end of an arc connection portion at the bottom of the bucket respectively. Horizontal reinforcing slats are welded to the outer portion of the arc connection portion at intervals. Longitudinal reinforcing plates are welded to the outer side of the front portion of the bottom of the bucket at intervals. The rear ends of the reinforcing plates are welded to the reinforcing slats. The front ends of the reinforcing plates are welded to the main cutter board. Longitudinal wear-resisting plates are arranged between the adjacent reinforcing plates and between the reinforcing plates and the left protection plate and the right protection plate. Compared with the prior art, the excavator bucket has the advantages that the structure rigidity is high, the structure design is more reasonable, the digging resistance is reduced, more materials are saved, and cost is saved.

Description

technical field [0001] The invention relates to a bucket, in particular to an excavator bucket. Background technique [0002] Excavator buckets are usually reinforced at the bottom of the bucket in order to avoid wear and collision dents at the bottom of the bucket; the reinforcement structure is generally as follows: 1. Add a One layer of horizontal reinforcement boards or one layer of vertical reinforcement boards; the simple reinforcement boards are placed horizontally to form concave-convex steps, so that when the front part of the bucket bottom is in contact with the soil, it will hinder the movement of the bucket and increase the excavation resistance. increase, and increase the wear of the reinforcement plate; the simple vertical placement also makes the rigidity of the bucket bottom weak; 2. In order to make the bucket bottom more rigid and wear-resistant, it will add 2 layers of reinforcement plates to the bottom of the bucket ; One layer is horizontal, and the oth...
