The direction away from cutting part 2 of angle extends, and wind-power lifting portion 3 is connected by fixed part 31 with cutting part 2.
Preferably, it is arranged fluted 233 on cutting part 2, the formation that the groove 233 and fixed part 31 match, when solid
When determining portion 31 and extending into groove 233, fixed part 31 can be connected by bolt with cutting part 2.
Preferably, at least one plate 32 windward is provided on cutting part 2, all plates windward 32 are along same rectilinear clearance
Arrangement, and adjacent two are provided with serrated knife on the opposite end face of plate 32 windward, serrated knife can pass through two windward between plate 32
The grass cuttings of gap are shredded.
Embodiment 2
As shown in figures 2-3, in the present embodiment, cutting part 2 includes cutting portion 23 and includes tool mounting portion 22.Against knife
The rotation direction of seat 1 is provided with cutting edge 21 on the preceding end face of cutting portion 23 and posterior end face；Wind-power lifting portion 3
It is set on cutting portion 23 and wind-power lifting portion 3 is detachably connected with cutting portion 23 by bolt；One end of tool mounting portion 22
It is fixedly connected with tool apron 1, the other end of tool mounting portion 22 is detachably connected by bolt with cutting portion 23.
At this point, there are stationary states and free state for cutting portion 23, and when cutting portion 23 is in stationary state, cutting portion 23
It can be fixedly connected with tool mounting portion 22；When cutting portion 23 in a free state, cutting portion 23 can be sent out relative to own axes
Raw rotation, the posterior cutting edge 21 of cutting portion 23 can go to front and wind-power lifting portion 3 can be with 21 rear of cutting edge
Cutting portion 23 is connected, also, the angle between wind-power lifting portion 3 and cutting portion 23 is constant.
For brief, cutting edge 21, cutting portion are provided on the preceding end face of cutting portion 23 and posterior end face
23 are detachably connected with tool mounting portion 22, wind-power lifting portion 3 is detachably connected with cutting portion 23.When the preceding end of cutting portion 23
After cutting edge 21 on face is worn, cutting portion 23 can be disassembled from tool mounting portion 22, then by the cutting portion
23 axis on its length direction rotates 180 degree, so that posterior end face and the location swap in front end face.Then by wind-force
Lifting parts 3 are removed and are re-installed on cutting portion 23, and when installation ensures the angle between wind-power lifting portion 3 and cutting portion 23 not
Become, i.e., so that the free end in wind-power lifting portion 3 always upward.Then, continued using the cutting edge 21 on rear end face
Vegetation is trimmed, cutting edge 21 does not need to replace whole blade when wearing, and has saved cost.
In order to increase the service life of cutting portion 23, in the present embodiment, as shown in figure 4, cutting portion 23 includes the first cutting
Area 231 and the second cutting region 232, and against the rotation direction of tool apron 1, the first cutting region 231 and the second cutting region 232 are preceding
Cutting edge 21 is provided on end face and posterior end face；Correspondingly, tool mounting portion 22 includes installing zone 221, when first
When cutting region 231 or the second cutting region 232 are located in installing zone 221, cutting portion 23 can be connected with tool mounting portion 22.
When the first cutting region 231 is in mowing state, in order to prevent on the second cutting region 232 or the first cutting region 231
Cutting edge 21 be worn, it is preferred, therefore, that installing zone 221 is recessed cavity, be provided with cutter on the second cutting region 232
The part of sword 21 can all can extend into recessed cavity.Conversely, if first cuts when the second cutting region 232 is in mowing state
The part that cutting edge 21 is provided in area 231 can all can also extend into recessed cavity.When the first cutting region 231 or the second is cut
When cutting area 232 and being located in recessed cavity, bolt can pass through the through-hole on fixation hole 234 and tool mounting portion 22 on cutting portion 23
222 are connected the two.
In blade use process, after two blades on the first cutting region 231 are all worn, by cutting portion 23 along it
The axis of width direction rotates 180 degree, so that the location swap of the first cutting region 231 and the second cutting region 232, and wind-force is mentioned
Ascending part 3 is disassembled from the first cutting region 231 is mounted on the second cutting region 232 and ensures that 3 free end of wind-power lifting portion is begun
All morning is upwards.Then the first cutting region 231 is extended into recessed cavity and fixes cutting portion 23 and tool mounting portion 22 and is connected
It connects, i.e., trims vegetation using the cutting edge 21 on the second cutting region 232.
It can be seen that including four cutting edges 21 on any one cutting portion 23, so that each cutting portion 23 can
Using four times, the utilization rate of cutting portion 23 is improved.Meanwhile when the cutting edge 21 on any one cutting portion 23 all wear with
Afterwards, corresponding cutting portion 23 is only needed to change, does not need together to replace tool apron 1 and tool mounting portion 22, saves material.
Further, as shown in figure 5, the wind-power lifting portion 3 in the present embodiment includes plate 32 and fixed part 31 windward, windward
One end of plate 32 is connected with fixed part 31, windward the other end of plate 32 and cutting part 2 have an angle away from cutting
The direction for cutting component 2 extends, and wind-power lifting portion 3 is connected by fixed part 31 with cutting part 2.
Preferably, as shown in figure 4, fluted 233 are arranged on cutting part 2, what which matched with fixed part 31
It is formed, when fixed part 31 extends into groove 233, fixed part 31 can be connected by bolt with cutting part 2.
Preferably, at least one plate 32 windward is provided on cutting part 2, all plates windward 32 are along same rectilinear clearance
Arrangement, and adjacent two are provided with serrated knife on the opposite end face of plate 32 windward, serrated knife can pass through two windward between plate 32
The grass cuttings of gap are shredded.
