Problems solved by technology

[0005] Moreover, because the thin teeth themselves are thin, the back of the wedge-shaped bucket tooth body 300 is also provided with grooves 331, 332, so the overall bucket teeth are thin, weak in strength, easy to break, and have poor wear resistance and poor durability. It is suitable for earthwork operations with less sand and gravel, but not suitable for stonework operations, and the replacement cycle is short, and the cost of use is high, which affects the working efficiency of the excavator

Abstract

The invention provides a digging bucket and bucket teeth of the digging bucket. Each of the bucket teeth comprises a wedge-shaped bucket tooth body, an upper thick tooth surface and an upper thin tooth surface, wherein the upper thick tooth surface is positioned at the upper surface of the wedge-shaped bucket tooth body; and the upper thin tooth surface is of a curved surface formed by downward depressing the upper surface of the wedge-shaped bucket tooth body, and is positioned at two sides of the upper thick tooth surface, and the projection of the curved surface, in the vertical plane, is of the projection region of a surrounding area. The strength and wear resistance of the bucket teeth can be improved, and the service lives of the bucket teeth can be prolonged.

Description

technical field [0001] The invention relates to engineering machinery, in particular to an excavator bucket and bucket teeth. Background technique [0002] Excavator is a kind of construction machinery, which is widely used in construction, road, mine and other engineering fields, and its main function is to carry out excavation operations. figure 1 It is the outline structure diagram of the existing excavator, such as figure 1 As shown, the working part of the excavator mainly includes a bucket (bucket) 110 , a stick (arm) 120 and a boom (boom) 130 . Among them, the bucket 110 is the main component that directly contacts the excavated gravel. figure 2 It is the outline structure diagram of the existing bucket, such as figure 1 , figure 2 As shown, the body 111 of the bucket 110 forms teeth 113 at the lower bottom edge of the mouth 112 . Bucket teeth 113 are used to plan hard ground or gravel, and cut into the ground. Therefore, bucket teeth 113 are generally made of ...
