Abstract
The utility model relates to a bucket of an excavator, and aims at providing an improvement of the bucket of the excavator. The bucket of the excavator has the advantages of being convenient to use and high in soft soil digging efficiency. The technical scheme includes that a non-alignment bucket tooth tunnel digging bucket comprises a bucket seat and a plurality of bucket teeth which are configured on the front of the bucket seat. The non-alignment bucket tooth tunnel digging bucket is characterized in that lengths of the plurality of bucket teeth are different, short bucket teeth are arranged in the middle, and long bucket teeth are arranged on two sides of the bucket teeth.
Description
Technical field
The utility model relates to a kind of scraper bowl of excavator.
Background technology
Excavator has purposes widely in every engineering construction; Especially in tunnel construction, bringing into play the effect that can not replace for operations such as weak soil excavation, hole shape are revised, got rid of the danger, slag tap, skim.But the scraper bowl of excavator is the earthwork scraper bowl of standard at present; In practice of construction was used, because of limitations such as the shape of scraper bowl, sizes, the restriction that is subject to was more.Especially in the weak surrounding rock stratum excavation in the tunnel, because existing power shovel adopts concordant bucket tooth, be difficult to insert mud stone, digging efficiency is not high, and progress is slow, and the effect of excavator is not utilized thoroughly.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, proposes a kind of improvement of power shovel, easy to use, the better characteristics of weak soil digging efficiency that this power shovel should have.
The technical scheme that the utility model provides is: a kind of tunnelling scraper bowl of non-concordant bucket tooth comprises the scraper bowl seat and is configured in scraper bowl seat several bucket tooths in front; It is characterized in that described several bucket tooths are different in size, what be positioned at the middle part is short bucket tooth, and what be positioned at both sides is long bucket tooth.
The length of described long bucket tooth is greater than short bucket tooth 50-100mm.
Described bucket tooth is 4-6.
The beneficial effects of the utility model are: when Specific construction, because the length of bucket tooth is inconsistent, at first long bucket tooth contacts with excavation surface.According to the Mudstone Characteristics in tunnel, under same active force, the contact area of its bucket tooth and excavation surface reduces, and pressure increases, and easily inserts in mud stone.After the long bucket tooth of both sides inserted mud stone, by the vibrations of scraper bowl, mud stone began to become flexible, and was conducive to remaining bucket tooth and continued to insert, thereby complete digging operation.Solved the problems such as the disturbance of domestic weak surrounding rock stratum adopting drilling and blasting method excavation and standard machinery excavation to exist is large, serious, the inefficiency of backbreaking, made it form the rapid construction ability.Accelerate the excavation progress, be conducive to improve work efficiency, produced significant economic and social benefit.

Fig. 2 is left TV structure schematic diagram of the present utility model.
Specific embodiments
The tunnelling scraper bowl of non-concordant bucket tooth described in the utility model comprises scraper bowl seat 3 and is configured in scraper bowl seat several bucket tooths in front; The quantity of described bucket tooth is generally 4-6, and tunnelling scraper bowl front is arranged in a row; Said structure and existing tunnel bucket are roughly the same.
Improvement of the present utility model is as shown in Fig. 1 embodiment: tunnelling scraper bowl bucket tooth in front is different in size, and wherein long bucket tooth 1 is 2, is installed on the both sides of scraper bowl seat 3, and length is greater than the short bucket tooth 2 of middle part; Short bucket tooth 2 is 2, is installed on the inboard of scraper bowl seat 3.
As preferably, be positioned at the long bucket tooth length of both sides greater than the short bucket tooth 50-100mm of middle part.
Above-mentioned bucket tooth is arranged in scraper bowl seat 3, can dismantle easily and change.
Claims (3)
1. the tunnelling scraper bowl of a non-concordant bucket tooth, comprise scraper bowl seat (3) and be configured in scraper bowl seat several bucket tooths in front; It is characterized in that described several bucket tooths are different in size, what be positioned at the middle part is short bucket tooth (2), and what be positioned at both sides is long bucket tooth (1).
2. the tunnelling scraper bowl of a kind of non-concordant bucket tooth according to claim 1, is characterized in that the length of described long bucket tooth is greater than short bucket tooth 50-100mm.
