Description
Technical field
This utility model relates to a kind of tractor trifilar suspension lifting arm, belongs to a kind of agricultural machinery three-link hitch neck
Territory.
Background technology
Existing tractor trifilar suspension lifting arm is usually and is made up of upper and lower screw rod and band female thread pipe, or by
Upper and lower loop bar and band outer stricture of vagina screw rod composition, typically with three big parts and two set positive/negative threads, screw rod needs the positive and negative spiral shell of car system
Stricture of vagina, this structure fabrication process is complicated.
Summary of the invention
This utility model, in order to overcome drawbacks described above, its object is to provide a kind of tractor trifilar suspension lifting arm.
This utility model to achieve these goals, adopts the following technical scheme that
A kind of tractor trifilar suspension lifting arm, it includes that U-shaped plate, U-shaped plate locking nut, fixing nut, interior hexagonal are tight
Determine screw, long bolt, set stem jam nut, loop bar；
Is connected in the middle of U-shaped plate and loop bar and has long bolt, at long bolt and U-shaped plate equipped with U-shaped plate locking nut,
Equipped with fixing nut in the middle of long bolt, the radial direction at fixing nut is provided with two symmetrical interior hexagonal screws, at set
One end of bar is equipped with set stem jam nut.
Further, described U-shaped plate base plate has a circular hole, has a pin through hole in Vertical U-type plate side.
Further, there is great circle step its one end of described long bolt, has one section of full thread, greatly below great circle step
Round platform rank are mounted below fixing nut.
Further, its one end of described loop bar is U-shaped plate, has a pin through hole in Vertical U-type plate side, the other end
Loop bar is a pipe, has female thread in one end of the draw.
Further, the both sides of described long bolt are respectively provided with two locking nuts.
Use long bolt to connect in the middle of U-shaped plate and loop bar, mainly by a set of threaded engagement, do not have positive/negative thread, screw thread to add
Work is convenient, and design of part is simple, and lifting arm is easy to adjust, and two locking nuts lock U-shaped plate and loop bar one end respectively, are connected firmly
Stable, make lifting arm assembly become a rigidity overall.
The beneficial effects of the utility model are: using long bolt to connect in the middle of U-shaped plate and loop bar, long bolt does not has positive and negative spiral shell
Stricture of vagina, screw thread process is convenient, and design of part is simple, and lifting arm is easy to adjust, and two locking nuts lock U-shaped plate and loop bar one respectively
End, is connected firmly stable, makes lifting arm assembly become a rigidity overall.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
1 pair of this utility model is described in detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of tractor trifilar suspension lifting arm, it includes U-shaped plate 1, U-shaped plate locking nut 2, fixing spiral shell
Mother 3, interior hexagonal screw 4, long bolt 5, set stem jam nut 6, loop bar 7.It is characterized in that: described lifting arm is at U
Is connected in the middle of template 1 and loop bar 7 and has long bolt 5, at long bolt 5 and U-shaped plate 1 equipped with U-shaped plate locking nut 2, growing
Equipped with fixing nut 3 in the middle of screw rod 5, the radial direction at fixing nut 3 is provided with two symmetrical interior hexagonal screws 4, at set
One end encapsulation stem jam nut 6 of bar 7.
Described U-shaped plate 1 base plate has a circular hole, has a pin through hole in Vertical U-type plate side.
Described long bolt 5 can use spheroidal graphite cast-iron to cast, and there is great circle step its one end, has one section below great circle step
Full thread, is mounted below fixing nut 3 at great circle step, fixing nut 3 be radially separately installed with two symmetrical in six
Angle screw 4.
Described loop bar 7 it the mode of welding can be used to manufacture.Its one end is U-shaped plate,
Having a pin through hole in Vertical U-type plate side, the loop bar of the other end is a pipe, has in one end of the draw
Female thread.
The both sides of described long bolt 5 are separately installed with two locking nuts.
This utility model one tractor trifilar suspension lifting arm work process is as follows:
When tractor work, farm tool frame is dropped to and needs farming ground, measure lifting arm length, then by farm implements machine
Frame rises to certain altitude, adjusts this height for the soil cultivating degree of depth.First two locking nuts are unclamped, by monkey spanner card
On fixing nut, plate moves long bolt and is adjusted to suitable length, then by both sides locking nut respectively and tight U-shaped plate and loop bar
One end, it is ensured that two ends stable connection is firm, makes lifting arm assembly become a rigidity overall.
