Abstract
The invention relate to a bidirectional rotating ground drill, which comprises an outer tube, an inner tube and an outer connecting piece, wherein the outer tube is sleeved in the bottom of the outer connecting piece; the inner tube is placed in the middle of the inside of the outer tube; the top end of the inner tube is inserted into an inner connecting piece casing, and is connected with one end of a rotating shaft through a split pin; the other end of the rotating shaft is arranged in a hollow spline shaft after passing through the middle hole of the outer connecting piece; the hollow spine shaft is in meshed connection with a connecting gear assembly; the bottom end of the inner tube is connected with a drill bit welding assembly positioned in the middle of the end part of the outer tube; external spiral blades are arranged on the excircle of the outer tube; the edges of the external spiral blades at the bottom end of the outer tube are connected with a plurality of square iron welding assembles through bolts; internal spiral blades are arranged on the excircle of the inner tube. According to the bidirectional rotating ground drill, two drill bits with different spiral directions are driven by two shafts with different rotating directions, so that excessive torque caused by ground drilling is reduced and even eliminated, operators can work more easily, and higher safety is achieved.
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
For physical prospecting, road construction, plantation fruit-bearing forest, hedge and autumn often using ground auger to applying fruit trees with fertilizer etc., to alleviate people's manual labor.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 controls drill bit on action bars and digs cave by being held in.
Existing ground auger structure is basic identical, uses single-screw drill bit can produce great moment of torsion when operation, effort and dangerous operation in, and while 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, by two contrary axles of direction of rotation, drive the different drill bits of two hands of spiral, reduce even to eliminate the very big moment of torsion causing while boring ground, lighter when operator is worked, safety is higher.
The technical solution adopted for the present invention to solve the technical problems is: a kind of double rotational directions ground boring device is provided, comprise outer tube, inner tube and outer connector, described outer tube is nested in the bottom of outer connector, described outer tube bosom is placed with inner tube, described inner tube top penetrates in interconnecting piece sleeve pipe, the one end that connects axis of rotation 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, the hollow splined shaft gear assembly that is connected with a joggle, the connection of described inner tube bottom is positioned at the drill bit weld assembly in the middle of outer tunnel end portion, on the cylindrical of described outer tube, be provided with external spiral blade, the edge that is positioned at the external spiral blade of outer tube bottom is bolted some square iron weld assemblies, on the cylindrical of described inner tube, be 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 pass are crossed welding manner and are fixed on outer tube.
Described interconnecting piece and internal helical blades are fixed on inner pipe by welding manner.
Described drill bit weld assembly and inner tube are bolted.
Between described internal helical blades and outer tube wall, leave gap.
Beneficial effect
The present invention has following advantage and good effect:
Moment of torsion while 1, using two different drill bits of rotation direction to reduce work, lighter when operator is worked.
Safety while 2, using this structure effectively to improve work.

As Figure 1-3, a kind of double rotational directions ground boring device, comprise outer tube 6, inner tube 2 and outer connector 8, described outer tube 6 is nested in the bottom of outer connector 8, described outer tube 6 bosoms are placed with inner tube 2, described inner tube 2 tops penetrate in interconnecting piece 4 sleeve pipes, the one end that connects axis of rotation 11 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 gear assembly 12 that is connected with a joggle, described inner tube 2 bottoms connections are positioned at the drill bit weld assembly 1 in the middle of outer tube 6 ends, on the cylindrical of described outer tube 6, be provided with external spiral blade 7, the edge that is positioned at the external spiral blade 7 of outer tube 6 bottoms is bolted some square iron weld assemblies 9, on the cylindrical of described inner tube 2, be 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 in inner tube 2 by welding manner with internal helical blades 3.
Described drill bit weld assembly 1 is bolted with inner tube 2.
Between described internal helical blades 3 and outer tube 6 inwalls, leave gap.
It is worth mentioning that, moment of torsion when the present invention uses two different drill bits of rotation direction to reduce work, lighter when operator is worked; Safety while using this structure effectively to improve work.
