Description

A kind of energy-saving electric earth auger
Technical field
The utility model relates to agricultural mechanical field, particularly a kind of energy-saving electric earth auger.
Background technology
Afforestation, fruit tree plants, tree grafting growth and dig the operation needs such as hole of topdressing a large amount of dig cave operation.Because trench digging mode breaks ground volume greatly, need trench digging mechanical output large, volume and weight is also corresponding comparatively large, and during operation, energy consumption is high, noise is large.And, because mechanical volume weight of ditching is large, be not suitable for mountain area, hills uniform slope larger area operation, also be not suitable for the operating environment of limited space, as orchard, tea place and mulberry field etc., these are local main based on manpower ditching-fertilizing at present, efficiency is lower, labor intensive.The existing hand-held machinery that burrows also can be used as fertilizer machinery, is generally be power source with two stroke gasoline engine, but adopts when such is mechanically activated and pull rope mode, and it is more difficult operate, and due to drill bit exposure, also there is potential safety hazard; During work, gasoline engine vibrations and noise are strongly, and very large on operator's impact during hand-held, add gasoline feeder exhaust emissions, long time continuous working has harmful effect to operator's health.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existed in prior art, provides a kind of low-power consumption, carries easy to operate energy-saving electric earth auger.
The purpose of this utility model is achieved through the following technical solutions:
A kind of energy-saving electric earth auger, comprising: handle 1, motor 2, power transmission shaft 3, sleeve 4, external spiral stator 5, the unidirectional expandable drill bit 6 in center, the tooth 7 that breaks ground, single direction ratchet 8 and inside spin stator 9; Motor 2 is fixed on handle 1; Power transmission shaft 3 is secured across handle 1 by bearing, and one end of power transmission shaft 3 is connected with motor 2, and the other end is directly connected with the unidirectional expandable drill bit 6 in center, power transmission shaft 3 is fixed with inside spin stator 9; Single direction ratchet 8 is fixed on power transmission shaft 3, and sleeve 4 is connected on power transmission shaft 3 by single direction ratchet 8; The external stability of sleeve 4 has external spiral stator 5, and the bottom of sleeve 4 is fixed with the tooth 7 that breaks ground.
The angle of the cone angle of the unidirectional expandable drill bit 6 in center can be changed by the rotation of power transmission shaft, can the angle of reduced cone angle when rotating counterclockwise, and can expand the angle of cone angle when rotating clockwise.
When the angle of the cone angle of the unidirectional expandable drill bit 6 in center narrows down to minimum angles, the edge diameter of the unidirectional expandable drill bit 6 in center is slightly less than inside spin stator 9, and just in time contacts with inside spin stator 9.
When the angle of the cone angle of the unidirectional expandable drill bit 6 in center opens up into maximum angle, the edge diameter of the unidirectional expandable drill bit 6 in center is slightly less than sleeve 4, can clamp the earth in sleeve 4.
When motor rotates forward, the unidirectional expandable drill bit in center is in contraction state, only plays the effect of breaking ground; During motor reversal, the unidirectional expandable drill bit in center expands, and plays stuck core effect.
Energy-saving electric earth auger of the present utility model, drive power transmission shaft by motor, sleeve is connected by single direction ratchet with power transmission shaft, and power transmission shaft and sleeve bore upper fixing internal and external screw stator, be rotated down when breaking ground and hack is discharged, form a hollow cylindrical core, during motor reversal, sleeve loses interlock, and the unidirectional expandable drill bit in center expands, block hollow cylindrical core, then take out core, avoid too much operation of breaking ground, thus decrease energy consumption of breaking ground.During work, when power transmission shaft 3 rotates counterclockwise, single direction ratchet 8 drive socket 4 rotates counterclockwise, and the unidirectional expandable drill bit 6 of tooth 7 and center that breaks ground cuts soil simultaneously, and hack is sent by external spiral stator 5 and inside spin stator 9, and whole earth auger moves to direction, underground; When reaching certain depth, motor 2 reverses, and power transmission shaft 3 rotates clockwise, and single direction ratchet 8 is slided, and sleeve 4 loses transmission, the unidirectional expandable drill bit 6 in center bottom power transmission shaft 3 centered by, expand angle, clamping core, lifting handle 1, takes out whole core.Compare existing earth auger structure, when power is identical, the area that breaks ground of the present utility model can promote more than twice.
The utility model compared with prior art has the following advantages and effect:
1, device of the present utility model breaks ground effective, and rate of breaking ground is little, energy-conservation;
2, simply portable, easy to operate, the applicable various landform of device of the present utility model.

Wherein: 1, handle; 2, motor; 3, power transmission shaft; 4, sleeve; 5, external spiral stator; 6, the unidirectional expandable drill bit in center; 7, break ground tooth; 8, single direction ratchet; 9, inside spin stator.
Embodiment
Below in conjunction with embodiment, further detailed description is done to the utility model, but embodiment of the present utility model is not limited thereto.
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3, Figure 4, energy-saving electric earth auger of the present utility model comprises handle 1, motor 2, power transmission shaft 3, sleeve 4, external spiral stator 5, the unidirectional expandable drill bit 6 in center, the tooth 7 that breaks ground, single direction ratchet 8 and inside spin stator 9; Motor 2 is fixed on handle 1; Power transmission shaft 3 is secured across handle 1 by bearing, and one end of power transmission shaft 3 is connected with motor 2, and the other end is directly connected with the unidirectional expandable drill bit 6 in center, power transmission shaft 3 is fixed with inside spin stator 9; Single direction ratchet 8 is fixed on power transmission shaft 3, and sleeve 4 is connected on power transmission shaft 3 by single direction ratchet 8; The external stability of sleeve 4 has external spiral stator 5, and the bottom of sleeve 4 is fixed with the tooth 7 that breaks ground.The angle of the cone angle of the unidirectional expandable drill bit 6 in center can be changed by the rotation of power transmission shaft, can the angle of reduced cone angle when rotating counterclockwise, and can expand the angle of cone angle when rotating clockwise.When the angle of the cone angle of the unidirectional expandable drill bit 6 in center narrows down to minimum angles, the edge diameter of the unidirectional expandable drill bit 6 in center is slightly less than inside spin stator 9, and just in time contacts with inside spin stator 9.When the angle of the cone angle of the unidirectional expandable drill bit 6 in center opens up into maximum angle, the edge diameter of the unidirectional expandable drill bit 6 in center is slightly less than sleeve 4, can clamp the earth in sleeve 4.
During work, make drill bit vertically ground, starter motor 2 makes power transmission shaft 3 rotate counterclockwise, single direction ratchet 8 drive socket 4 rotates counterclockwise, grab steady handle 1 by electronic earth auger toward pressing down, the unidirectional expandable drill bit 6 of tooth 7 and center that breaks ground cuts soil simultaneously, and hack is sent by external spiral stator 5 and inside spin stator 9, and whole earth auger moves to direction, underground.When reaching certain depth, motor 2 reverses, and drive power transmission shaft 3 to rotate clockwise, single direction ratchet 8 is slided, sleeve 4 loses transmission stall, and the unidirectional expandable drill bit 6 in center opens, and bottom power transmission shaft 3 centered by, expand angle, clamping core, lifting handle 1, takes out whole core.On ground, motor 2 rotates forward by other positions again, and the unidirectional expandable drill bit 6 in center shrinks, and core landing from sleeve 4, completes and once play cave operation.
