Referring to Fig. 1 and Fig. 2 descriptions according to the pull rod device and land leveller described in this utility model some embodiments.
As depicted in figs. 1 and 2, the pull rod device 10 that the embodiment of this utility model first aspect is provided, is arranged on level land
On machine, land leveller includes turning circle 20, perching knife support member 30 and the perching knife 40 on perching knife support member 30, perching knife support member
30 are connected with turning circle 20, and can be rotated relative to turning circle 20, and pull rod device 10 includes：First drag link sleeve 11 and the first pull bar
12。
Specifically, one end of the first drag link sleeve 11 can be rotated with turning circle 20 and is connected；One end of first pull bar 12 is located at
In first drag link sleeve 11, and first drag link sleeve can be stretched out to adjust the first pull bar 12 with respect to 11 axial stretching of the first drag link sleeve
11 length, and the other end of the first pull bar 12 and perching knife support member 30 rotate and be connected；Wherein, the length of pull rod device 10 is adjusted
During section, perching knife support member 30 drives perching knife 40 to rotate relative to turning circle 20, to change the cutting angle between perching knife 40 and ground.
The pull rod device 10 that the embodiment of this utility model first aspect is provided, by the first pull bar 12 and the first drag link sleeve
Axial stretching between 11 is realizing the length adjustment of pull rod device 10, and then realizes that pull rod device 10 adjusts the purpose at shovel angle,
As the cost of mechanical pull rod device 10 is than relatively low, it is thus possible to effectively reduce the manufacturing cost of land leveller, and pull rod device 10
Telescopic adjustment it is simple to operate, and can realize that mechanism is locked, synchronicity is relatively good.
Specifically, pull rod device 10 includes the first drag link sleeve 11 being sequentially connected and the first pull bar 12, and mechanical shovel soil in level land is made
During industry, only need to need to adjust the length that the first pull bar 12 stretches out the first drag link sleeve 11 according to operating mode, you can drive perching knife support member
30 rotate relative to turning circle 20 so that the angle between perching knife support member 30 and ground changes, so realize perching knife 40 with
The change at cutting angle between ground, then locks the first pull bar 12 and the first drag link sleeve 11, you can be fixed on 40 angle of perching knife
Desired location.During adjustment, as pull rod device 10 can realize that machinery is locked, therefore, when land leveller has left and right
During two perching knife support members 30, two pull rod device 10 can be adjusted to into identical length easily and be fixed on the position,
Therefore the synchronicity of two perching knife support members 30 is can effectively ensure that, and then ensure effective regulation at shovel angle.
In such scheme, it should be noted that the axial stretching of 12 relative first drag link sleeve 11 of the first pull bar can pass through
Various ways realize that such as, the first pull bar 12 is sheathed in the first drag link sleeve 11, and be threaded connection (the first pull bar 12 with
One of first drag link sleeve 11 can rotate), rotate the first pull bar 12 or the first drag link sleeve 11 i.e. axle of the first pull bar of scalable 12
To extension elongation, and the first pull bar 12 and the first drag link sleeve 11 are locked at into ad-hoc location by screw thread.For another example, the first pull bar 12
It is sheathed in the first drag link sleeve 11, and relative can slides, by locking device or limiting component limiting the axle of the first pull bar 12
To extension elongation.
In some embodiments of the present utility model, in the first pull bar 12 and the first drag link sleeve 11 is provided with spacing
Portion, another is provided with spacing auxiliary section, and limiting section is engaged with spacing auxiliary section, can limit the first pull bar 12 relative first
11 axial stretching of drag link sleeve.
In the above-described embodiments, by limiting section and spacing auxiliary section come realize the first pull bar 12 and the first drag link sleeve 11 it
Between locking and unblock, connection is reliable and easy to operate；As for the axial stretching between the first pull bar 12 and the first drag link sleeve 11
Mode, can be relative slip, or screw telescopic or other modes.
In one embodiment of the present utility model, as shown in figure 1, spacing auxiliary section include it is multiple along pull rod device 10
The first connecting hole 111 that length direction is arranged, limiting section include connector and at least one second connecting holes 121, connector energy
Enough run through the first connecting hole 111 and the second connecting hole 121, to limit 12 11 axial stretching of relative first drag link sleeve of the first pull bar.

Preferably, as shown in figure 1, the distance between second adjacent connecting hole 121 is not equal to the first adjacent connecting hole
The distance between 111.
Multiple first connecting hole, 111 equidistantly distributeds so that the length adjustment amplitude of pull rod device 10 can realize ladder
Change, so, only need to can be visually known the length change of pull rod device 10 according to the quantity of first connecting hole 111 at interval
Situation, adjusts more convenient.Certainly, multiple first connecting holes 111 can also non-equidistance distribution, such as according to shovel angle etc.
The length change amplitude of the corresponding pull rod device of amplitude variationization 10 also can arranging the distance between corresponding first connecting hole 111
Preferable adjustment effect is played enough, as the technical scheme is without departing from design philosophy of the present utility model and objective, so
In protection domain of the present utility model.
Axially disposed multiple connecting holes on the first pull bar 12 and the first drag link sleeve 11, due to the second adjacent connection
The distance between hole 121 is not equal to the distance between first adjacent connecting hole 111, then the first different connecting hole 111 and not
More combinations can be realized between the second same connecting hole 121, so as to refine the length adjustment amplitude of pull rod device 10, Jin Erti
The degree of regulation at 10 pairs of shovel angles of high pull rod device.As between multiple second connecting holes, can be with spaced set, it is also possible to non-etc.
Spacing is arranged.
In second embodiment of the present utility model, the first pull bar 12 is provided with limiting section, sets on the first drag link sleeve 11
Limited location auxiliary section；Spacing auxiliary section includes multiple hole clippings arranged along 10 length direction of pull rod device, and limiting section includes elasticity
