Description
Technical field
The invention belongs to ground auger technical field, particularly relate to a kind of double rotational directions ground boring device.
Background technology
Often need to use ground auger, to alleviate the manual labor of people to applying fruit trees with fertilizer etc. for physical prospecting, road construction, plantation fruit-bearing forest, hedge and autumn.In existing ground auger, because single ground auger is applicable to various landform, efficiency is high, is easy to carry and therefore the operation of field, field is widely used.Common single ground auger is by small utility gasoline engine, and the drilling tool of gear-box and particular design forms.Operator action bars controls drill bit digs cave by being held in.
Existing ground auger structure is substantially identical, uses single-screw drill bit can produce great moment of torsion when operating, and operation is required great effort and dangerous, and when causing use, facility, safety are low not.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of double rotational directions ground boring device, the different drill bits of two hands of spiral are driven by the axle that two direction of rotation are contrary, reduce even to eliminate the very big moment of torsion caused when boring ground, more light when operator is worked, safety is higher.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of double rotational directions ground boring device, comprise outer tube, interior pipe and outer connector, described outer tube is nested in the bottom of outer connector, interior pipe is placed with in the middle of described outer tube, described interior pipe top penetrates in interconnecting piece sleeve pipe, one end of axis of rotation is connected by cottor pin, the other end of described axis of rotation is through after the mesopore of outer connector, be contained in hollow splined shaft, hollow splined shaft is connected with a joggle gear assembly, described interior pipe bottom connects the drill bit weld assembly be positioned in the middle of outer tube end, the cylindrical of described outer tube is provided with external spiral blade, the edge being positioned at the external spiral blade of outer tube bottom is bolted some square iron weld assemblies, the cylindrical of described interior pipe is provided with internal helical blades.
Described hollow splined shaft is contrary with the direction of rotation of axis of rotation.
Described outer connector and external spiral blade are fixed on outer tube by welding manner.
Described interconnecting piece and internal helical blades are fixed on inner pipe by welding manner.
Described drill bit weld assembly and interior pipe are bolted.
Gap is left between described internal helical blades and outer tube wall.
Beneficial effect
The present invention has following advantage and good effect:
1, the drill bit that use two rotation directions are different reduces moment of torsion during work, lighter when operator is worked.
Safety when 2, using this structure effectively can improve work.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is dentition sectional view of the present invention.
Fig. 3 is that dentition of the present invention faces enlarged drawing.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As Figure 1-3, a kind of double rotational directions ground boring device, comprise outer tube 6, interior pipe 2 and outer connector 8, described outer tube 6 is nested in the bottom of outer connector 8, described outer tube 6 bosom is placed with interior pipe 2, described interior pipe 2 top penetrates in interconnecting piece 4 sleeve pipe, one end of axis of rotation 11 is connected by cottor pin 5, the other end of described axis of rotation 11 is through after the mesopore of outer connector 8, be contained in hollow splined shaft 10, hollow splined shaft 10 is connected with a joggle gear assembly 12, described interior pipe 2 bottom connects the drill bit weld assembly 1 be positioned in the middle of outer tube 6 end, the cylindrical of described outer tube 6 is provided with external spiral blade 7, the edge being positioned at the external spiral blade 7 of outer tube 6 bottom is bolted some square iron weld assemblies 9, the cylindrical of described interior pipe 2 is provided with internal helical blades 3.
Described hollow splined shaft 10 is contrary with the direction of rotation of axis of rotation 11.
Described outer connector 8 is fixed on outer tube 6 by welding manner with external spiral blade 7.
Described interconnecting piece 4 is fixed on interior pipe 2 by welding manner with internal helical blades 3.
Described drill bit weld assembly 1 is bolted with interior pipe 2.
Gap is left between described internal helical blades 3 and outer tube 6 inwall.
It is worth mentioning that, the drill bit that the present invention uses two rotation directions different reduces moment of torsion during work, lighter when operator is worked; Safety when using this structure effectively can improve work.
