1, the cutting edge part cutting resistance of drilling bucket bottom is big, and its reason is because angle and drilling bucket base plane that its cutting edge was do not have fillet surface;
2, drive the bucket linkage and occupied native passage, making into, soil resistance increases;
3,, barrel body wall is thickened and make and deposit native space and reduce by drilling bucket outer wall transfer torque;
4, the bottom is opened discharge height is increased, and closes fashionable need and forward to not have and unload Tu Qu and realize pressing bucket to close closing, increased cycle time for working;
5, unload soil by gravity dumping, the inwall of bucket is easily gathered by cohesive soil and makes and effectively deposit native space and dwindle.
(3) summary of the invention
To be solved in the utility model is exactly drilling bucket cutting and to advance soil resistance big in the prior art, inwall easily amasss problems such as clay, and a kind of novel structure, the uniqueness that provide are easy to make, cost is low, easy to operate and safe and reliable axial whole open-type rotary drilling digger.
The technical solution of the utility model realizes by following measure.Axial whole open-type rotary drilling digger, comprise drum shape staving, the unlatching suspension rod is equipped with at the top of staving, open suit back-moving spring on the suspension rod, the below of opening suspension rod is provided with the automatic locking that links with it, automatic locking is provided with back-moving spring, cylindrical extension bar is housed in the staving, the top of extension bar is connected with borer drill rod, the guiding bracing frame is equipped with on the top of extension bar, and the linear drill bit of many curved surfaces of monolithic spiral flow is equipped with in the bottom of extension bar, and lead rail axis is to the inwall that is fixedly connected on staving, limited block is fixedly connected on the below of guide rail, and is connected with staving.
The linear drill bit of described many curved surfaces of monolithic spiral flow is formed by monoblock cast, and the curved surface of its drill bit is the axial screw shape, comprises cutting edge, transition face and storage surface three parts, and cutting edge partly is axial involute bending, radially is parabolic; Circumferentially reaching of transition face radially all is arc surface; Storage surface is the plane; The thickness of its drill bit curved surface circumferentially reaches radially to be and increases progressively shape, crop is located at the outside of cutting edge, the middle part of cutting edge is provided with several circular-arc bucket tooths, and the center, lower end of drill bit is provided with the alloy apex point that is the chisel edge shape, is provided with cutting slot between alloy apex point and the cutting edge part.
Owing to adopted said structure, the utlity model has following conspicuous advantage:
1, the inner no linkage of drilling bucket advances soil resistance and reduces.
2, adopt the linear drill bit of monolithic many curved surfaces spiral flow, apex point partly is provided with cutting slot, thereby has reduced cutting resistance.
3, it is more obvious that the guiding bracing frame has effect, the especially clay soil of automatic removing earth.
4, the drilling bucket closure need not to land, thereby cycle time for working is shortened.
5, novel structure, uniqueness are easy to make, and cost is low, and is easy to operate, are applicable to that revolving of various models dig churn.
