Description
Technical field
The present invention relates to graden machine equipment technical field, more particularly to a kind of weeding for being conveniently replaceable cutter
Machine.
Background technology
Lawn is important part in modern garden greening, and the combinations of lawn and trees, flowers constitutes a variety of more
The Green Landscape of sample.It is essential to obtain regular maintenance for lawn, and the trimming on lawn is numerous lawn maintenance works
One of bother and the most frequently work the most in work.
Initial people are manually mowed by using reaping hook, and so not only labor intensity is big, and efficiency is low, takes
When it is laborious while turf-mown flatness it is uneven.So being trimmed at present using hay mover to lawn, operate
Personnel need to only control the operation of hay mover, without being mowed manually, reduce manual labor amount while increasing efficiency.At present
Most of hay movers carry out the trimming on lawn using motor driven rotating blade, and blade holds very much under long-term high speed rotational operation
Easily go wrong, at this moment need to carry out blade maintenance replacing, or need to change different knives in face of different weedings requirement
During piece, but existing weeder blade exchange is fairly cumbersome, adds the replacing difficulty of blade, the weeding ratio of reduction.
The content of the invention
It is an object of the invention to：In order to solve the problems, such as existing weeder cutter changing trouble, the present invention provides a kind of
It is conveniently replaceable the weeder of cutter.
The present invention specifically uses following technical scheme to achieve these goals：
A kind of chassis for being conveniently replaceable the weeder of cutter, including being provided with some wheels, chassis side are provided with handle,
The weeding hole of circle is offered on chassis, it is characterised in that：Also include being arranged on the rotary cutter below weeding hole with being arranged on
Motor above weeding hole, the output shaft of motor are connected through weeding hole with rotary cutter, output shaft distal end faces center
The groove of circle is axially offered, screw thread is provided with groove inner wall, half tooth bolt, half tooth bolt polished rod portion is provided with groove
Spiral chute is provided with cyclotomy week, the depth of spiral chute is exported by increasing successively on half tooth bolt top to end direction
The fixing hole of communication groove is symmetrically offered on the periphery of axle both sides, fixing hole is divided into big hole section and close output close to groove
The aperture section of axle periphery, sets fix bar in fixing hole, and the thick bar that fix bar includes being arranged in big hole section is small with being arranged on
Thin bar in hole section, spring is arranged with thin bar, thick bar end is stretched out fixing hole and is engaged with spiral chute bottom land, described
Rotary cutter includes axle sleeve and axle sleeve blade provided circumferentially about, and axle sleeve both sides radially offer spacing with fixing hole cooperation
Hole.
Further, some spacing holes for being used to adjust blade setting height(from bottom) are provided with axle sleeve.
Further, collecting chamber is provided with above weeding hole, collecting chamber side is provided with collecting pipe, collects pipe end connection
There is the collecting box being arranged on chassis, blower fan is provided with collecting box.
Further, fix bar both-side ends are arc-shaped
Beneficial effects of the present invention are as follows：
1st, using the cooperation between spacing hole and fixing hole, half tooth bolt need to only be rotated, you can make by spiral chute solid
Determine the fix bar in hole to stretch out and pass through spacing hole, realize and be relatively fixed installation between output shaft and axle sleeve, reverse rotation is
The separation dismounting of the two can be achieved, the design is simple in construction, easy to operate, only cutter changing need to can be achieved by once rotating
Handling, greatly reduce lay day of cutter, improve the efficiency of weeding.
2nd, axially arranged some spacing holes on axle sleeve are passed through, you can real using the cooperation between fixing hole and different spacing holes
The setting height(from bottom) of cutter is now adjusted, to reach different weeding height, meets the weeding requirement for height in different places.
3rd, in weeder normal work, the blower fan operating in collecting box produces suction, by collecting pipe by under collecting chamber
It is unified in grass cuttings suction collecting box caused by cutting at square rotary cutter to collect, avoid grass cuttings and fly away everywhere, eliminate weeding
The work to the secondary cleaning of lawn progress is needed afterwards.
4th, the arc-shaped of fix bar end effectively prevent fix bar end stretch out with retract during with spacing hole
Conflict is produced, also makes the slip that fix bar can be more smooth in spiral chute, has further facilitated behaviour of the cutter in handling
Make.

Embodiment
In order to which those skilled in the art are better understood from the present invention, below in conjunction with the accompanying drawings with following examples to the present invention
It is described in further detail.
Embodiment 1
It is a kind of to be conveniently replaceable the weeder of cutter, including the chassis 1 of some wheels 2 is provided with, the side of chassis 1 is provided with handle
Hand 10, the weeding hole 6 of circle is offered on chassis 1, it is characterised in that：Also include the rotary cutter for being arranged on the lower section of weeding hole 6
With the motor 4 being arranged on above weeding hole, the output shaft 5 of motor 4 is connected through weeding hole 6 with rotary cutter, output shaft 5
Distal end faces are central axial to offer circular groove 19, is provided with screw thread on the inwall of groove 19, half tooth is provided with groove 19
Bolt 17, the smooth bar part of half tooth bolt 17 is provided circumferentially about spiral chute 18, and the depth of spiral chute 18 is by half tooth bolt 17
Increase successively on top to end direction, the fixing hole 14 of communication groove 19 is symmetrically offered on the both sides periphery of output shaft 5, Gu
It is the big hole section 14-2 and the aperture section 14-1 close to the periphery of output shaft 5 close to groove 19 to determine hole point 14, is set in fixing hole 14
Fix bar 15 is put, fix bar 15 includes the thick bar 15-2 being arranged in big hole section 14-2 and the thin bar being arranged in aperture section 14-1
Spring 16 is arranged with 15-1, thin bar 15-1, thick bar 15-2 ends are stretched out fixing hole 14 and are engaged with the bottom land of spiral chute 18,
Described rotary cutter includes axle sleeve 12 and the blade 11 provided circumferentially about of axle sleeve 12, and the both sides of axle sleeve 12 are radially offered with fixing
The spacing hole 13 that hole 14 coordinates.
Operation principle：When cutter needs to change, half tooth spiral 17 is rotated, fix bar 15 is slid into along spiral chute 18
The end of half tooth bolt 17, because the depth of spiral chute 18 is increased successively by the top of half tooth bolt 17 to end, is now fixed
Bar 15 shrinks in fixing hole 14 to the side of groove 19 under the action of the spring 16, so that thin bar 15-1 parts in fix bar 15
Shrink the spacing hole 13 on axle sleeve 12, unloaded so that cutter separates with output shaft 5, when Cutting tool installation manner, by axle sleeve
Spacing hole 13 on 12 is directed at fixing hole 14, reversely rotates half tooth bolt 17, protrudes into the thin bar 15-1 in fix bar 15
In spacing hole 13, so that cutter is relatively fixed with output shaft 5.
Using the cooperation between spacing hole and fixing hole, half tooth bolt only need to be rotated, you can fixation is made by spiral chute
Fix bar in hole is stretched out and passes through spacing hole, is realized and is relatively fixed installation, reverse rotation between output shaft and axle sleeve
The separation dismounting of the two is realized, the design is simple in construction, easy to operate, only cutter changing need to can be achieved by once rotating
Handling, the lay day of cutter is greatly reduced, improve the efficiency of weeding.
