Problems solved by technology

[0004] At present, the disassembly and assembly process of the gear head is relatively difficult. During the assembly process, it is necessary to use a lot of strength to swing the hammer to drive the gear pin in. It also requires a lot of effort to smash the gear pin out during the disassembly process.
Therefore, it is laborious and time-consuming during the disassembly and assembly of the tooth head, and at the same time, there are potential safety hazards in the beating process

Embodiment 1

[0040] See figure 1 , The bucket tooth provided in this embodiment is applied to the bucket in construction machinery, such as excavators, loaders and other construction machinery. The bucket is an important part of the working device of this type of construction machinery, and the bucket teeth are Important parts of excavators are prone to wear out after long-term operation and need to be replaced.

[0041] The traditional bucket teeth are difficult to install and disassemble. The main reason is that the connecting pin needs to be directly driven with a hammer with great strength, and there are great safety hazards in the beating process. In addition, the connecting pin after disassembly will be deformed to a certain extent, which seriously affects the secondary use of the connecting pin.

[0042] The starting point of this embodiment is to solve the problems in the prior art by providing a bucket tooth that can be installed and disassembled without beating, has a simple structure...

Embodiment 2

[0072] See Figure 1 to Figure 8 , The bucket tooth provided in this embodiment is applied to buckets in construction machinery, such as excavators, loaders and other construction machinery. The starting point of this embodiment is to solve the problems in the prior art by providing a bucket tooth that can be installed and disassembled without beating, has a simple structure, is convenient and quick to disassemble and assemble, and the disassembly process is safer. Compared with the first embodiment above, this embodiment has the following main differences:

[0073] For details, please refer to figure 2 with image 3 In this embodiment, the boss 30 is in clearance fit with the groove 33 on the outer arc surface of the connecting pin 3, and the boss 30 is an elastic boss 30. It can be understood that the elastic boss 30 can be relatively telescopic in the groove 33, and then the boss 30 can enter the track 101 after being compressed, and generate a thrust to the track 101, and t...

Embodiment 3

[0083] See Figure 1 to Figure 8 , The bucket tooth provided in this embodiment is applied to buckets in construction machinery, such as excavators, loaders and other construction machinery. The starting point of this embodiment is to solve the problems in the prior art by providing a bucket tooth that can be installed and disassembled without beating, has a simple structure, is convenient and quick to disassemble and assemble, and the disassembly process is safer. Compared with the above-mentioned first or second embodiment, the main difference between this embodiment is:

[0084] For details, please refer to figure 2 with image 3 In this embodiment, the pair of connecting pins 3 are the first pin 3a and the second pin 3b, respectively. The first pin 3a and the second pin 3b are in interference fit in the second shaft hole 100, in other words Therefore, the opposite ends of the first pin 3a and the second pin 3b are matched with each other.

[0085] It is understandable that t...

Abstract

The invention provides a bucket tooth, a bucket and an excavator, related to the field of engineering machinery. The bucket tooth comprises a tooth base, a tooth head and a pair of connection pins, external arc surfaces of the pair of connection pins both are provided with lug bosses, a first axle hole arranged on the tooth head is corresponding to a second axle arranged on the tooth base, two rails are arranged in the second axle hole, and accommodating areas adaptive to the lug bosses are arranged at tail ends of the rails. While assembling, the tooth head is inserted and connected on the tooth base, the pair of connection pins respectively pass through the first axle hole, stretch into the axle hole and further drive the lug bosses to enter into the accommodating areas along the rails,thus, connection between the tooth head and the tooth base is realized; and while disassembling, the connection pins are just taken off from the rails. The bucket tooth, the bucket and the excavator provided by the invention are simple in structure and convenient and easy to assemble and disassemble, and in assembling and disassembling processes, striking the connection pins with great force is not needed, so the assembling and disassembling processes are safer. The bucket tooth is used on the bucket of the engineering machinery, the bucket tooth is time-saving and labor-saving in the assembling and disassembling processes, and can improve working performance of the engineering machinery.

Description

Technical field [0001] The invention relates to the field of engineering machinery, and in particular to a bucket tooth, a bucket and an excavator. Background technique [0002] The working device of the excavator in the construction machinery is equipped with a bucket, which is suitable for earth and stone construction projects. [0003] The bucket is equipped with bucket teeth. The bucket teeth are an important part of the excavator. They are similar to human teeth and are also vulnerable parts. They are combined bucket teeth composed of a tooth seat and a tooth head, which are connected by a tooth pin. Because the part of the bucket tooth wear and failure is the tooth head, just replace the tooth head. [0004] At present, the process of disassembling and assembling the tooth head is relatively difficult. During the assembling process, it is necessary to manually swing a hammer to drive the tooth pin in. During the disassembly process, a great effort is also required to push the ...
