Abstract
The utility model discloses a detachable drilling tool of an earth boring machine. The detachable drilling tool of the earth boring machine comprises a detachable drill bit, a joy stick, a motor which drives the drill bit to rotate and a drive shaft which is connected between the drill bit and the motor. The drill bit comprises a connecting part, a screw hole is formed in the connecting part, and the drill bit and the drive shaft are connected into a whole through the connecting part. The drill bit is composed of a drill stem, blades, tool aprons, and a drill point, the upper tool apron and the lower tool apron which are symmetrical in the radial direction are arranged on the drill stem, the two blades used for cutting soil are fastened to the tool aprons, the tool aprons and the tool stem are fixed together, and the connecting part is connected with the drive shaft in a detachable mode. By means of the earth boring machine, detachable separation of the drill bit and the earth boring machine is well achieved, cost is saved to a large extent, and the blades can be replaced according to demands and damaged conditions.
Description
[technical field]
The utility model relates to a kind of machine bit of digging pit, and relates in particular to the detachable brill cutter of a kind of trench excavator.
[background technology]
Traditional plantation trees are generally adopted and dig with a pick, spade digs etc. manually digs pit, and this mode of digging pit is not only required great effort but also time-consuming.Personnel are easily tired, and efficiency is too slow.Therefore, occurred adopting trench excavator to substitute the mode of manually digging pit.
Existing general trench excavator is adopted drill bit and is digged pit, drill bit is the cutter that must apply in trench excavator, annual use amount is very large, the drill bit and the trench excavator that use at present are generally the welded type overall structure, tool wear is just scrapped processing after reconditioning or tipping afterwards again, causes scrapping of whole trench excavator.
[utility model content]
The utility model is for existing trench excavator drill bit design and use the problem existed, provide a kind of drill bit that can make to dismantle and separate with trench excavator, thereby change the detachable brill cutter of trench excavator of the drill bit of trench excavator, this drill bit has not only extended the life-span of trench excavator greatly, and has saved greatly cost.
Know-why and scheme that the utility model adopts for achieving the above object are:
The detachable brill cutter of trench excavator of the present utility model, the motor and one that comprises demountable bit, control stick, driving bit is connected in the driving shaft between described drill bit and motor, drill bit comprises a junction, connecting portion is provided with a screw, drill bit is integrally connected by connecting portion and driving shaft, drill bit comprises that a drilling rod, a blade, a tool rest and apex point section form, on drilling rod, arrange one on the other, two tool rests of radial symmetric, on tool rest, be fixed wtih two blades of cutting soil, tool rest and described drilling rod are fixing together, the movable dismounting of connecting portion and driving shaft.
The utility model has the advantage of: because drill bit of the present utility model detachably separates with trench excavator, thereby make the drill bit of trench excavator can change at any time when wearing and tearing occurring or damage, so not only extended the life-span of trench excavator, and avoided causing whole trench excavator not use and the situation of cost of idleness because drill bit damages.
[accompanying drawing explanation]
Fig. 1 is the trench excavator overall structure schematic diagram that the utility model is implemented;
Fig. 2 is the detachable brill cutter of trench excavator schematic diagram in Fig. 1;
Fig. 3 is connecting portion structural representation in Fig. 1;
[specific embodiment]
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Referring to Fig. 1-Fig. 3, the present embodiment provides a kind of trench excavator detachable brill cutter, drill bit and trench excavator 100 are separable, and trench excavator 100 comprises that the motor 10 and of demountable bit, control stick 20, driving bit is connected in the driving shaft 30 between described drill bit and motor 10.
The control that the user realizes trench excavator 100 positions and direction by control stick 20.
Drill bit comprises a junction 40, described connecting portion 40 is provided with a screw 401, described drill bit is integrally connected by described connecting portion 40 and driving shaft 30, described drill bit comprises that a drilling rod 50, a blade 60, a tool rest 70 and apex point section 80 form, on drilling rod 50, arrange one on the other, two tool rests 70 of radial symmetric, on described tool rest 70, be fixed wtih two blades 60 of cutting soil, described tool rest 70 and described drilling rod 50 are fixing together, described connecting portion 40 and the movable dismounting of described driving shaft 30.
Motor 10 directly connects driving shaft 30 and drives driving shaft 30 runnings, screw 401 on connecting portion 40 is by motor 10, control stick 20 and the drill bit one that is screwed together, driving shaft 30 drives drilling rod 50 rotations, and the apex point section 80 and the blade 60 that are positioned on drilling rod 50 can cut soil, realize digging pit.
In the utility model, drill bit and trench excavator screw togather together by screw 401, realize separating with the detachable of trench excavator integral body, and the model of drill bit can be changed with the soil hardness difference, also can change with damage and the degree of wear of drill bit.
In addition, the blade in this practicality newly also can be changed with service failure and the demand of digging pit.
Adopt trench excavator of the present utility model, realized well that not only drill bit and the detachable of trench excavator separate, saved greatly cost, and blade also can be changed with demand and damaged condition.
Preferably, between described connecting portion 40 and driving shaft 30, be bolted.
Preferably, tool rest 70 is provided with screw, and the corresponding described screw of drilling rod 50 is provided with screw thread, and tool rest 70 and drilling rod 50 screw togather together.
Preferably, on tool rest 70, fix respectively a blade.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should wrap in the utility model scope.
