Description
Technical field
The utility model belongs to excavator technical field; Relate to a kind of multifunctional excavator demountable bit specifically.
Background technology
Along with the sustainable development of China's economy, in order to increase work efficiency in the work progress of power system and building system, reduce the labour intensity of workman, mostly multifunctional excavator is all adopted to carry out the concrete operations of constructing, as china national practical new-type patent 201220687376.0 the multifunctional excavator that uses, larger application is just had in electric power and building system, the excavator that past uses is all that drill bit and drilling rod connect as one, but due in the process of breaking ground, when running into the soil structure of geological condition complexity, the anterior bit wear of excavator is larger, like this in the process of more bit change, also will drilling rod be changed together simultaneously, so the resource of the enterprise of waste greatly, and reduce the service efficiency of machinery, improve the labour intensity of workman, certain loss is brought to the normal production of enterprise.
Summary of the invention
Goal of the invention of the present utility model:
Mainly in order to provide a kind of dismountable drill bit structure of excavator front portion, in use changing more simple and convenient, improving the service efficiency of machinery, reduce the labour intensity of the workman of entreprise cost.
The technical solution of the utility model is:
Provide a kind of multifunctional excavator demountable bit, comprise drilling rod body, drilling rod body is provided with helical blade, the bottom of drilling rod body is provided with dismounting drill bit, and dismounting drill bit is connected with drilling rod body by bearing pin, and the bottom of dismounting drill bit is provided with the node that breaks ground, dismounting drill bit is also provided with delivery sheet, delivery sheet is directly connected with helical blade, and the bearing pin that dismounting drill bit is connected with drilling rod body is at least two, and the angle between bearing pin is 45 °.
The beneficial effects of the utility model are:
Effectively reduce the cost of production of enterprise, improve the production efficiency of enterprise, reduce the labour intensity of workman.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure; 1 is drilling rod body; 2 is helical blade; 3 is dismounting drill bit; 4 is bearing pin; 5 is the node that breaks ground; 6 is delivery sheet.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, provide a kind of multifunctional excavator demountable bit, comprise drilling rod body 1, drilling rod body 1 is provided with helical blade 2, dismounting drill bit 3 is provided with in the bottom of drilling rod body 1, dismounting drill bit 3 is connected with drilling rod body 1 by bearing pin 4, the bottom of dismounting drill bit 3 is provided with the node 5 that breaks ground, dismounting drill bit 3 is also provided with delivery sheet 6, delivery sheet 6 is directly connected with helical blade 2, the bearing pin that dismounting drill bit is connected with drilling rod body is at least two, and the angle between bearing pin is 45 °, in concrete work progress, workman carries out construction operation by directly changing dismounting drill bit, and do not need to change whole jackrod structure, and in the process changed, can change after only needing bearing pin to dismantle, greatly improve the production efficiency of machinery, reduce the labour intensity of workman, and the hazards reduced in work progress, improve production safety, in use, the node that breaks ground of dismounting drill bit bottom is by after hard clods breaking, helical blade is sent to by delivery sheet, then soil property is transported away, production efficiency is high, safe ready.
