Embodiment 1

[0030] A bucket tooth installation device that is easy to replace includes a tooth seat 2, a tooth tip 1 with a pin hole, and a pin shaft 3 connecting the tooth tip 1 and the tooth seat 2 through the pin hole.

[0031] The tooth holder 2 includes a middle hinge part 21 , a tooth end connection part 22 connected with the tooth tip 1 , and a tail end connection part 23 clamped and connected with the excavator bucket through the middle hinge part 21 .

[0032] The middle hinge part 21 includes an upper connecting block, and a lower connecting block hinged with the upper connecting block through a hinge rod;

[0033] The tail end connecting portion 23 includes an upper clamping piece integrally formed with the upper connecting block, and a lower clamping piece integrally formed with the lower connecting block;

[0034] The tooth end connecting portion 22 includes an upper tooth portion integrally formed with the upper connection block, and a lower tooth portion integrally formed w...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that in this embodiment, the structure between the excavator bucket and the tooth seat 2 is optimized, and the structure between the upper tooth portion and the lower tooth portion is optimized at the same time. The specific settings are as follows:

[0040] The excavator bucket is provided with a protruding part at the connection with the tooth seat 2, and the connection with the excavator bucket on the lower clamping part or / and the upper clamping part is provided with a matching protruding part. groove.

[0041] The upper tooth portion or / and the lower tooth portion are provided with a blocking member 4 that prevents the pin shaft 3 from moving between the upper tooth portion and the lower tooth portion.

[0042] Through the optimization of the above structure, the connection between the excavator bucket and the tooth holder 2 and between the tooth holder 2 and the tooth tip 1 is effectively promoted to be mo...

Embodiment 3

[0044] The difference between this embodiment and Embodiment 2 is that the specific structure of the resistance member 4 is optimized in this embodiment, and the specific settings are as follows:

[0045] There are more than two resistance members 4 , all of which are arranged along a direction perpendicular to the central axis of the pin shaft 3 . In this embodiment, both the upper teeth and the lower teeth are provided with resistance members 4, and the number of upper resistance members 4 on the upper teeth and the lower teeth is respectively set to five, as figure 2 shown. In the upper tooth portion, three of the resistance members 4 are arranged on one side of the central axis of the pin shaft 3, and the other two are arranged on the other side of the central axis of the pin shaft 3, such as figure 2 shown. Similarly, two stoppers 4 are provided on one side of the lower teeth corresponding to the upper teeth with three stoppers 4, and one side of the lower teeth corre...

Abstract

The invention discloses a bucket tooth mounting device convenient to change, and solves the problem that existing structure bucket teeth are very inconvenient to change. The bucket tooth mounting device comprises a tooth holder (2), a tip (1) having a pinhole, and a pin (3) connecting the tip (1) and the tooth holder (2) through the pinhole, and is characterized in that the tooth holder (2) comprises a middle hinging portion (21), a tooth end connection portion (22) connected with the tip (1), and a tail connection portion (23) connected with an excavator bucket through the middle hinging portion (21). The bucket tooth mounting device has the advantages of good convenience in separating and assembly operations, good connection stability, simple structure and the like.

Description

technical field [0001] The invention relates to a bucket tooth, in particular to an easy-to-replace bucket tooth installation device. Background technique [0002] At present, most of the bucket teeth on the market are composed of tooth bases and tooth tips connected by pin shafts, and the tooth bases are fixed on the excavator bucket to realize the excavation effect of the excavator bucket. [0003] However, the teeth on the existing excavator buckets need to be connected and disassembled twice to realize the separation and assembly between the tooth seat, the tooth tip and the bucket. Therefore, it is very inconvenient to install and replace the bucket teeth in the existing structure. Contents of the invention [0004] The present invention mainly solves the problem of inconvenient installation and replacement of bucket teeth in the existing structure, and provides an easy-to-replace bucket tooth installation device that solves the above problems. [0005] The present ...
