Description
Technical field
The utility model relates to a kind of function lever apparatus, more particularly, to a kind of perching knife operating stick.
Background technique
Perching knife is the device of bull-dozer postposition, for loosening the soil or ploughing.The sidesway oil cylinder pushing perching knife at the perching knife back side is along sliding
Rail does lateral sliding.Cutting angle, which adjusts oil cylinder, can change the shovel Tu Jiao of perching knife.
The front end of the structure hitch frame of perching knife is a hinged ball, is hinged and connected with the front end of front frame, the fixed revolution in rear end
Circle, is connected by lifting cylinder and rocker with land leveller front frame, perching knife is connect with turning circle, in the driving of device for revolving and driving
Lower drive perching knife revolution.The sidesway oil cylinder pushing perching knife at the perching knife back side does lateral sliding along sliding rail.Cutting angle adjusts oil cylinder can be with
Change the shovel Tu Jiao of perching knife.Therefore, grader is able to carry out the movements such as lifting, inclination, sidesway, extraction and 360 ° of revolutions,
Its position can adjust in a big way, to meet land leveller level land, cutting, side shifting soil, roadbed forming, slope trimming etc.
Operation.
Therefore the perching knife used is usually provided with multiple operating sticks, wherein mainly including ejector dozer operating stick, perching knife lifting
Operating stick and perching knife revolution operating stick etc., the frequency that the native angle operating stick of traditional shovel uses is higher, is usually an integral molding structure,
And interfering due to operating stick, it is therefore desirable to set fold-line-shaped for operating stick, shovel native angle operating stick use process
In often problem appear to is that the one end connecting with perching knife easily snaps off, and traditional operating stick is an integral molding structure, and is fractureed
After need integral replacing operating stick, in this way caused by higher cost, and the wasting of resources is be easy to cause, because of other portions of operating stick
Position is intact, but can only become waste product.
Utility model content
The purpose of this utility model is to cause resource unrestrained to solve not repairing after connecting rod fracture in existing operating stick
The problem of taking provide a kind of native angle operating stick of perching knife shovel.
The deficiency of the utility model to solve above-mentioned technical problem, used technical solution is:
A kind of native angle operating stick of perching knife shovel, including operating stick and axle sleeve, wherein one end of operating stick are fixed on axle sleeve, institute
Extension rod is also connected in the operating stick stated, extension rod and operating stick are in 120 ° of angles, are also connected with connecting rod on axle sleeve, connect
It is in 30 ° of angles between bar and the center line of operating stick, connecting rod is twisted in threaded hole far from threaded hole is offered on one end of axle sleeve
Equipped with transiting rod, the external screw thread being mutually matched with threaded hole is machined on transiting rod, transiting rod is far from solid on one end of connecting rod
Surely have connection ring, the connecting hole connecting with perching knife offered in connection ring, be connected through a screw thread transiting rod is changed to it is detachable
Structure is not necessarily to integral replacing if transiting rod can replace transiting rod after fractureing, to save cost, transiting rod is located at outer
At least three planes along the distribution of transiting rod length direction are machined on outer wall between screw thread and connection ring, when transiting rod fractures
When it is disassembled from connecting rod convenient for clamping transiting rod by flat clamping.
The externally threaded length being arranged on the transiting rod outer wall is less than the depth of threaded hole.
The outer diameter of the transiting rod is equal to the 1/2 of connecting rod outer diameter.
The center line of connecting hole under the use state and the centerline parallel of axle sleeve.
The beneficial effects of the utility model are: the utility model dismantles the easy fracture position design of traditional operation bar
Formula structure can directly be replaced after fracture, to can not repair after solving the problems, such as the fracture of traditional operation bar, while in mistake
It crosses and is provided with planar structure on bar, avoid the problem of can not taking out after being broken appearance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Diagram label: 1, extension rod, 2, operating stick, 3, axle sleeve, 4, connecting rod, 5, connection ring, 6, transiting rod, 7, screw thread
Hole.
Specific embodiment
As shown in the figure, specific embodiment is as follows:
A kind of native angle operating stick of perching knife shovel, including operating stick 2 and axle sleeve 3, wherein one end of operating stick 2 are fixed on axle sleeve 3
On, extension rod 1 is also connected in the operating stick 2, extension rod 1 and operating stick 2 are in 120 ° of angles, are also connected on axle sleeve 3
Connecting rod 4, is in 30 ° of angles between connecting rod 4 and the center line of operating stick 2, and connecting rod 4 offers on one end far from axle sleeve 3
Threaded hole 7 twists in threaded hole 7 and is equipped with transiting rod 6, is machined with the external screw thread being mutually matched with threaded hole 7, transition on transiting rod 6
Bar 6 is fixed with connection ring 5 on one end far from connecting rod 4, the connecting hole connecting with perching knife is offered in connection ring 5, passes through spiral shell
Transiting rod 6 is changed to Demountable by line connection, if transiting rod 6 can replace transiting rod 6 after fractureing, more without entirety
It changes, to save cost, transiting rod 6 is machined at least three along transition on the outer wall between external screw thread and connection ring 5
The plane of 6 length direction of bar distribution clamps transiting rod by flat clamping for it from connecting rod when transiting rod 6 fractures
It is disassembled on 4.
The externally threaded length being arranged on 6 outer wall of transiting rod is less than the depth of threaded hole 7.
The outer diameter of the transiting rod 6 is equal to the 1/2 of 4 outer diameter of connecting rod.
The center line of connecting hole under the use state and the centerline parallel of axle sleeve 3.
The utility model and adjusts connecting hole before use, in the threaded hole for needing that transiting rod 6 is first screwed into connecting rod 4
Then the centerline parallel of center line and axle sleeve 3 will penetrate shaft in axle sleeve, connection ring is connect with perching knife, was then operated
Extension rod 1 is pulled in journey can be realized adjustment, when transiting rod 6 is broken, since the diameter of transiting rod 6 is less than the straight of connecting rod 4
For diameter so fracture location is positively located on transiting rod, the plane for needing clamping to be located on transiting rod outer wall at this time takes transiting rod
Out, the transiting rod then more renewed.
Technical solution cited by the utility model and embodiment and non-limiting, with skill cited by the utility model
Art scheme and embodiment be equivalent or effect same approach is all in the range of the utility model is protected.
