Abstract
The utility model provides a large-capacity bucket tooth which belongs to the technical field of machinery. The large-capacity bucket tooth settles the following problems when particle-shaped material is dig by the prior bucket tooth with a smooth surface or curved surface as a working surface: inconvenient carrying, and high difficulty in digging. The large-capacity bucket tooth comprises a tooth tip, an operation part and a connecting part. The operation part is arranged between the tooth tip and the connecting part. The tooth tip, the operation part and the connecting part are in an integrated structure. Two sides of the connecting part are provided with through connecting holes. The end of the connecting part is provided with two symmetrically arranged mounting ports in the vertical direction of the working surface of the working part. A reinforcing rib is arranged on a front working surface and a back working surface of the working part. One end of the reinforcing rib is connected with a tooth tip, and the other end is connected with the connecting part. Furthermore the height of the reinforcing rib gradually enlarges from the tooth tip end to the connecting part end. The tooth tip is plate-shaped. The width of the tooth tip is same with that of the working part. The large-capacity bucket tooth has the following advantages: simple structure, high convenience in mounting, large carrying amount, high economic performance and high practicability.

Background technology
Along with the fast development of China's economic construction, particularly country strengthens the investment to highway, railway, house and water conservancy projects, and excavator more and more demonstrates the great function in the development of the national economy.Bucket tooth is the important easy consumption parts on excavator, due to the easy wear out failure of bucket tooth, so need often to change bucket tooth.General existing bucket tooth is sharp knife shape with the crown position that material directly contacts, during work and the contact area of material little, the amount of carrying is little, is not suitable for the softer soil of soil property.Such bucket tooth has increased the time of work, and efficiency is not high, and is impracticable.In addition, the work plane of bucket tooth is level and smooth plane or curved surface,, running into while being granular material, carries inconvenience, and is more difficult during excavation.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of simple in structure, easy to assembly, super capacity bucket tooth that the amount of carrying is large, economical and practical.
the purpose of this utility model can realize by following technical proposal: a kind of super capacity bucket tooth, comprise crown, operate portions and connecting portion, described working position is between crown and connecting portion, described crown, operate portions and connecting portion are the integral type structure, it is characterized in that, described connecting portion dual-side offers the connecting hole that connects, described connecting portion end offers two symmetrically arranged installing ports along operate portions work plane vertical direction, be provided with reinforcing rib along direction of axis line on positive and negative two work planes of described operate portions, described reinforcing rib one end is connected with crown, the other end is connected with connecting portion, and the height of reinforcing rib raises gradually from crown end to connecting portion end, described crown shape is plate shape, described crown width and operate portions width equate, two connecting holes are arranged with boss outward, described connecting hole passes boss.
Crown is shaped as plate shape, crown width and operate portions width equate, the contact area of bucket tooth and material in the time of can increasing work like this, the setting of reinforcing rib on operate portions, when bucket tooth leaves material, a part of material can be carried in the reinforcing rib both sides, compares the existing bucket tooth amount of carrying and increases, and is economical and practical, simple in structure, the setting of boss, reduced the wearing and tearing of connecting hole, extended the application life of bucket tooth.
In above-mentioned super capacity bucket tooth, described crown cross section is isosceles trapezoid.Be formed with the gradient between the work plane of crown and operate portions, reduced the contact area of crown and material, make the crown concentrated stress large, when bucket tooth is worked, can make the excavator bucket dental transition go deep into material.
In above-mentioned super capacity bucket tooth, described installing port is a square breach.Excavator bucket teeth comprises bucket tooth and toothholder, and it is more firm that the setting of square breach is fixed on toothholder bucket tooth, good stability.
In above-mentioned super capacity bucket tooth, described operate portions end has cancave cambered surface and arc transition to the connecting portion place.The design, destroy of cancave cambered surface in the mining process compacted material, along the trend of operate portions top mobile, reduced excavating resistance, alleviated the wearing and tearing of bucket tooth self.
In above-mentioned super capacity bucket tooth, the length of described crown is L, 1.8mm≤L≤3mm.
Compared with prior art, the utlity model has following advantage:
1, the connecting portion dual-side offers the connecting hole that connects, the connecting portion end offers two symmetrically arranged installing ports along operate portions work plane vertical direction, installing port is a square breach, excavator bucket teeth comprises bucket tooth and toothholder, it is more firm that the setting of square breach is fixed on toothholder bucket tooth, good stability.
2, be provided with reinforcing rib along direction of axis line on positive and negative two work planes of operate portions, reinforcing rib one end is connected with crown, the other end is connected with connecting portion, and the height of reinforcing rib raises gradually from crown end to connecting portion end, when bucket tooth left material, a part of material can be carried in the reinforcing rib both sides, compared the existing bucket tooth amount of carrying and increased, economical and practical, simple in structure.
3, the crown shape is plate shape, the crown cross section is isosceles trapezoid, crown width and operate portions width equate, the contact area of bucket tooth and material in the time of can increasing work like this, be formed with the gradient between the work plane of crown and operate portions, reduced the contact area of crown and material, make the crown concentrated stress large, when bucket tooth is worked, can make the excavator bucket dental transition go deep into material.
4, the operate portions end has cancave cambered surface and arc transition to the connecting portion place, the design, destroy of cancave cambered surface in the mining process compacted material, along the trend of operate portions top mobile, reduced excavating resistance, alleviated the wearing and tearing of bucket tooth self.
