Excavator bucket

Abstract

The invention relates to an excavator component, and particularly discloses a bucket. The bucket comprises a bucket body with an opening in the rear end, wherein a guide groove is formed in the upperwall of the bucket body, the rear lower end of the bucket body is hinged to a bottom cover, a guide block matched with the guide groove is arranged at the upper end of the bottom cover, and the bucketcapacity is reduced when the bottom cover rotates forwards, and is increased otherwise; a traction base is arranged at the outer end of the guide block and is hinged to a traction arm, and a threadedsleeve is arranged at the other end of the traction arm; and a swing seat is arranged above the bucket body, a main shaft and a motor device are arranged on the swing seat, and the main shaft is matched with the threaded sleeve so that the position of the bottom cover can be adjusted through rotation to adjust the bucket capacity. The bucket has the bucket capacity adjusting function and can be adjusted according to actual working conditions, and therefore the operation efficiency can be improved to the maximum extent on the premise that stable work of an excavator is guaranteed; the bucket capacity is convenient and fast to adjust, so that time and labor are saved; and a spare bucket is not required to be arranged, so that the equipment acquisition cost is reduced, and the defects of labor consumption, operation efficiency reduction and the like of the spare bucket in transportation, disassembling and assembling are eradicated.

Description

Technical field

[0001] The invention relates to an accessory of an excavating machine, in particular to a bucket for an excavating machine.Background technique

[0002] Bucket is an important component of excavator, and its capacity, namely bucket capacity, is one of the three most important parameters (operating weight, engine power and bucket capacity) of an excavator. The bucket capacity of the original bucket is usually the standard bucket capacity, which is not suitable for all working conditions. For example, for light materials with lower density, a bucket with a larger capacity should be used to reduce power consumption and improve work efficiency. For heavy materials with higher density, a bucket with a smaller bucket capacity should be selected to avoid overloading of the excavator to ensure its working stability. Therefore, excavators usually need to be equipped with multiple spare buckets with different bucket capacities to meet the needs of different working conditions. This ...
