Beneficial effects of the present invention:Motor is arranged in the present invention on chassis, when lifting platform is displaced downwardly to minimum point, motor
It is rotated with rope sheave connecting band running rope wheel, casing mechanism is pulled by drawstring, using the isolated design of motor and casing mechanism,
Will not be by the vibration influence of motor in use process, and towed structure, casing mechanism be can be made smaller, and are suitable for use in
Operation on smaller field;Borehole drill construction is also set up on chassis simultaneously, can be inserted in the hole to surface drilling and using drilling rod,
To fix chassis, enabling chassis in operation process is not in sidesway.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the invention, specific structure and generation
Clear, complete description, to be completely understood by the purpose, feature and effect of the invention.Each skill in the invention
Art feature, can be with combination of interactions under the premise of not conflicting conflict.
Referring to figs. 1 to Fig. 3, a kind of small-sized towed drag links are set on the chassis 1 including the chassis 1 with traveling wheel
It is equipped with lifting platform 2 moving up and down, borehole drill construction 3 and motor 4 are provided on the lifting platform 2, the borehole drill construction 3 wraps
Dismountable drilling rod 31 is included, one end of the drilling rod 31 is helical-blade bit end, and the other end is cylinder body end, the cylinder body end
Diameter is not more than the outer diameter of helical-blade bit end, and the shaft of the motor 4 stretches out the bottom surface of lifting platform 2 and perpendicular to chassis 1,
The shaft of the motor 4 is connect with borehole drill construction 3, and for driving drilling rod 31 to rotate, the chassis 1 is wound with drawing being provided with
The rope sheave 6 of rope 5,6 axis of rope sheave is overlapped with the axis of 4 shaft of motor, described when lifting platform 2 is displaced downwardly to minimum point
4 turns of thes tip of the axis of motor are connect with rope sheave 6, left side and its end of the pull direction of the drawstring 5 perpendicular to chassis 1
It being detachably connected with a hand-held casing mechanism 8, the chassis 1 is provided with fixation hole 11 on the position close to 6 right side of rope sheave,
The cylinder body end of the drilling rod 31 can pass through the fixation hole 11 from top to bottom.31 helical-blade bit end of drilling rod after the drilling bore hole of ground,
By cylinder body end pass through the fixation hole 11 insertion ground hole after can fixed frame 1, due to drawstring 5 pull casing mechanism 8 work
It firmly acts on rope sheave 6, fixation hole 11 is arranged in the position on the right side of rope sheave 6, allow the pull direction of drawstring 5, the axis of rope sheave 6
The axis of line and fixation hole 11 is in the same plane, in this way can more preferable fixed frame 1.
To the embodiment of borehole drill construction 3, referring to Fig. 3 and Fig. 4, the borehole drill construction 3 further includes being rotatably connected going up and down
It fifth wheel 32 on platform 2, the belt wheel 33 being fixedly connected in the shaft of motor 4 and is wound on belt wheel 33 and fifth wheel 32
Belt 34 is provided with ring gear on the fifth wheel 32, is provided between the helical-blade bit end and cylinder body end of the drilling rod 31
The outer gear ring 311 that can cooperate with ring gear, the helical-blade bit end are provided with retaining ring 312 on the position close to outer gear ring 311,
The cylinder body end is provided with the telescopic fixture block for being stuck in 32 upper surface of fifth wheel on the position close to outer gear ring 311
313.When in use, after lifting lifting platform 2, fixture block 313 is pressed, the cylinder body end of drilling rod 31 is allowed up to insert from 32 lower section of fifth wheel
Enter fifth wheel 32, until the upper surface of retaining ring 312 and the lower end face contact of fifth wheel 32, outer gear ring 311 is fully inserted at this time
Ring gear, fixture block 313 is located at the upper surface of fifth wheel 32 at this time and auto-extending is stuck in upper end surface, and drilling rod 31 is enabled to will not fall
Under, drilling rod 31 can carry out bore operation to ground at this time;To remove drilling rod 31, fixture block 313 is pressed first, lifts lifting platform 2,
Due to do not have fixture block 313 block and gravity, drilling rod 31 will not rise with lifting platform 2, continue to lift lifting platform 2 until
Drilling rod 31 is kept completely separate with fifth wheel 32, can remove drilling rod 31.Further improved, settable inclined-plane on fixture block 313 allows brill
When the cylinder body end of bar 31 is up inserted into from 32 lower section of fifth wheel, inclined-plane is contacted with fifth wheel 32 can force fixture block 313 to move back automatically
Contracting, does not need to be pressed with hand, easier for installation.
Further improvement is embodiment, and the lifting platform 2 includes at least three 21 Hes of guide post being vertically set on chassis 1
The plate 22 moving up and down on guide post 21 is covered, drop handle 221 is provided on the plate 22, is provided with and helps on the chassis 1
Hand II 12 is provided with crossbeam 13 on the handrail II 12, shadoof 10 is hinged on the crossbeam 13, the shadoof 10 is mentioned across this
Ring 221.In practice, guide post 21 has four, and be arranged shadoof 10 allow itself and pass through drop handle 221, be easy for operator and lift plate
22, while while also facilitating drilling, applies pressure to plate 22.
Further improvement is embodiment, and referring to Fig. 2 and Fig. 3,4 turns of thes tip of the axis of the motor are that section is regular polygon
Structure, being provided at the axis of the rope sheave 6 can be regular polygon with the section of the shaft end clearance fit of motor 4
Cavity.By clearance fit, 4 turns of thes tip of the axis of motor is enabled to be easily accessible in cavity, user, which works as, turns the tip of the axis and cavity
When not being aligned, rope sheave 6 can be rotated manually and enables its alignment, into mating connection.
In addition, the casing mechanism 8 include rack 81,8 front of rack is set walking directive wheel 82, be separately positioned on
Two panels trailing bar 83 at left and right sides of 8 rear portion of rack and the handrail I 84 that 8 rear upper of rack is set, the end of the drawstring 5
The front end of rack 8 is hooked by a fastener in end.Rack 8 is hooked using fastener, when not needed detachably, is disconnected, this is covered
The structure of native mechanism 8 only has necessary component, compact-sized, small in size, convenient for manipulation.
The present invention lifts lifting platform 2, plugs drilling rod 31 in use, chassis 1 is shifted on the fit position of ridge, connects
Electric power, motor 4 drive drilling rod 31 to rotate, and operation shadoof 10 controls drilling rod 31 and drills out hole location on ground, lift lifting after the completion
Platform 2 removes drilling rod 31, pushes chassis 1 that fixation hole 11 is enabled to be aligned with the hole location on ground, and the cylinder body end of drilling rod 31 is passed through and is fixed
Hole 11 is inserted into hole location, and chassis 1 is fixed at this time, then puts down shadoof 10 and the shaft end of motor 4 and the cavity of rope sheave 6 is enabled to match
Connection is closed, motor 4 drives rope sheave 6 to rotate after energization, and drawstring 5 pulls casing mechanism 8 mobile, at this time the controllable handrail of user
I 84, casing mechanism 8 is controlled, the trailing bar 83 of two sides will roll soil topples over toward both sides, seed or seedling to both sides
Carry out earthing.The present invention replaces traditional engine with motor, advantageously reduces vibration, and use towed structure, keeps away
Exempt from motor 4 to the vibration influence of casing mechanism 8, the volume with season casing mechanism 8 be can be made smaller ingeniously, is suitble to smaller
Field on operation.
It should be noted that it is above only in conjunction with the embodiments further elucidated above to the present invention, it does not constitute to the present invention
The limitation of protection scope only realizes the invention if simply being changed to this technology with essentially identical means
Purpose, all should belong to protection scope of the present invention.
