Description
Technical field
This utility model is related to land leveller, more specifically, it relates to a kind of land leveller of width adjustable.
Background technology
Land leveller is the major mechanical for being used for shaping and leveling operation in earth work, is widely used in highway, airport level land
The large-area Land leveling operation such as machine.Also indispensable effect is played in municipal works.Why land leveller has extensively
General less important work ability, is to complete 6 degree of motions in space due to its clean-up scraper.They individually can be carried out, it is also possible to
Combination is carried out.Land leveller can provide enough strength and stabilities for roadbed in subgrade construction.Its master in subgrade construction
Method is wanted to have grading operation, brush slope operation, railway embankment.
During level land, due to operating mode complexity, it is sometimes desirable to which wider perching knife increases soil-shifting amount, it is sometimes desirable to narrow by one
A little perching knives reaches flexible effect., due to there was only perching knife, operationally soil-shifting amount is very little for land leveller of the prior art, it is impossible to
Realize the regulation of perching knife width.
For the problems referred to above, a kind of level land of width adjustable disclosed in the Chinese patent of Publication No. CN2040982U
Machine, is characterized in that：Actuating unit is provided with the rear cabin of land leveller, the driver's cabin, the bottom of actuating unit set
There is rear portion road wheel, support beam being provided with driver's cabin front portion, the support beam front lower portion is provided with directive wheel, level land perching knife is arranged on
Below the middle part of support beam, two pieces of additional perching knives are fixedly connected on the two ends rear portion of level land perching knife.
The program solve the problems, such as land leveller work when width inadequate, but due to additional perching knife be fixed, it is impossible to
Adapt to all operating modes, perching knife can not need adjusting size according to operating mode, it is therefore desirable to propose a kind of new scheme to solve this
Problem.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of level land of width adjustable

Specific embodiment
With reference to the accompanying drawings and examples, this utility model is described in detail.
Embodiment one：A kind of land leveller of width adjustable, as depicted in figs. 1 and 2, including body 1, support beam 2, is propping up
The lower section of support beam 2 is provided with perching knife 3, and perching knife 3 includes that main perching knife 4 and secondary perching knife 5, main perching knife 4 are provided with guiding groove, secondary perching knife
5 are provided with guide protrusions is mutually fitted together to the guiding groove of main perching knife 4, allows secondary perching knife 5 to slide in the horizontal direction.Main perching knife 4
Bottom is fixed with rotating shaft 8, and rotating shaft 8 is rotatably connected by second connecting rod 7 and secondary perching knife 8, and first connecting rod 6 and second connecting rod 7 are rotated
Rotary shaft 15 is connected to, the stopper slot 14 of vertical direction on secondary perching knife 4, is provided with, rotary shaft 15 is stuck in stopper slot 14 and can be with
Slide in stopper slot 14.First connecting rod 6 is rotatably connected and has vertical direction in the top of second connecting rod 7, the upper end of first connecting rod 6
Primary push rod 10, the top of primary push rod 10 is connected with power set 9, and power set 9 are cylinder.
When road surface is wider, only with 4 width of main perching knife not enough, need using secondary perching knife 5.Cylinder is moved downward, and promotes master
Push rod 10 is moved downward, and primary push rod 10 forms thrusts oliquely downward by the secondary perching knives 5 of first connecting rod 6 pairs, now due to
Gathering sill is provided between main perching knife 4 and secondary perching knife 5 so that secondary perching knife 5 can only be moved in the horizontal direction, in pushing away for first connecting rod 6
Power effect under, secondary perching knife 5 is sliped off to both sides in the horizontal direction, so as to reach the purpose for expanding main 4 width of perching knife, be adapted to compared with
The operation in broad way face.When road surface is narrower, it is only necessary to which main perching knife 4 works independently, and cylinder is moved upwards, while pulling first connecting rod
6 move upwards, and now, the secondary perching knife 5 of first connecting rod 6 pairs produces power obliquely so that secondary perching knife 5 is inwardly sliding in the horizontal direction
Dynamic, secondary perching knife 5 withdraws, and now only main perching knife 4 works.
Embodiment two：A kind of land leveller of width adjustable, as shown in figure 3, the difference from embodiment one is：Main shovel
Rotating disk 11 is installed on knife 4, and dynamic source 12 on rotating disk 11, power source 12 are rocking handle, and the first company is fixedly connected with rotating disk 11

Top slidably connect primary push rod 10, first connecting rod 6, primary push rod 10 are slidingly and sealingly connected with sleeve 13 respectively, primary push rod
10 and first connecting rod 6,7 junction of second connecting rod have seal with elastometic washer, in sleeve 13 formed cavity.The top of primary push rod 10 connects
Power set 9 are connected to, power set 9 are cylinder.
When road surface is wider, need using secondary perching knife 5, cylinder is run downwards, promote 10 downward operation of primary push rod, compression is empty
Intracavity gas, now in compressive state, generation thrust promotes 7 outside sidesway of first connecting rod 6 and second connecting rod to empty intracavity gas
Dynamic, first connecting rod, second connecting rod promote two pair 5 outside Slideslips of perching knife again, and now pair perching knife 5 stretches out and the work together of main perching knife 4
Make, adapt to the wider operating mode in road surface.When road surface is narrower, cylinder drives primary push rod 10 to run up, and is now formed in cavity true
Sky, first connecting rod 6 and second connecting rod 7 drive secondary 5 inside operation of perching knife under atmospheric pressure effect, now secondary perching knife 5 withdraw and
Main perching knife 4 overlaps, and only main perching knife 4 works, and adapts to the narrower operating mode in road surface.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
