Description
Technical field
The utility model relates to a kind of agricultural machinery, belong to agricultural machinery technological field, especially relating to one kind can be used for
The hitch frame of various balers.
Background technique
Pickup formula square bale baler is for carrying out field to the stalks class herbaceous plant such as herbage, corn stover, wheat straw, straw
Between compress bundling automatically into side or round bale, keep bale solid, storage, convenient transportation.All kinds of pickup formula balers are at home
Production time is not grown, and technology is not mature enough, needs constantly to improve into raw, the needs for being allowed to adapt to Chinese agriculture production.The machine at present
It has the following problems: when turning operation, due to tractor driver's misoperation, being easily damaged tractor inter-axle shaft, Universal drive
Axis and the power input shaft for picking up formula square bale baler；Tractor hydraulic rear linkage on rough road when walking
It is easy top bad universal drive shaft.
Summary of the invention
The utility model provides a kind of traction mechanism of the baler of axial-rotation, horizontal hunting and up and down adjustment.
A kind of hitch frame for baler, hitch frame include connecting cross beam, fluted disc mounting base, axle sleeve, attachment pegs and lead
Draw crossbeam；Fluted disc mounting base is separately mounted to the both ends of the connecting cross beam, and one end of draw beam is connected to fluted disc peace through fluted disc
It fills on seat, the axle sleeve of the other end of draw beam is flexibly connected through attachment pegs and traction crossbeam；
Wherein fluted disc by two it is pairs of divide fluted disc to form, divide the back side of fluted disc to be respectively welded at fluted disc mounting base and traction
Liang Shang；Fluted disc is divided to be intermeshed together through involute teeth；When draw beam angle is adjusted, fluted disc clamping screw passes through annular ring
Fluted disc is locked.
Further, it is clearance fit between above-mentioned axle sleeve and attachment pegs, rotates axle lock nut and rotary shaft limits spiral shell
Bolt cooperates axle sleeve axial limiting in attachment pegs.
The beneficial effects of the utility model are: dividing fluted disc through involute teeth intermeshing plus annular ring；Make in front and back
Height between connecting cross beam is adjusted.
Between axle sleeve and attachment pegs for gap, limit cooperation, prevent axle sleeve from moving axially, can only radial rotating, thus
Achieve the purpose that baler and tractor traveling are non-interference in broken terrain.

Specific embodiment
The invention will be further described with reference to the accompanying drawing:
Referring to shown in Fig. 1, Fig. 2, hitch frame includes connecting cross beam 1, fluted disc mounting base 2, rotary shaft 5, draw beam 4 and traction
Crossbeam 6；Two fluted disc mounting bases 2 are mounted on connecting cross beam 1, and one end of two draw beams 4 links together through fluted disc 3, draw beam 4
The other end be flexibly connected through rotary shaft 5 and traction crossbeam 6.
Wherein fluted disc 3 by two it is pairs of divide fluted disc to constitute, two pairs of to divide fluted disc to be respectively welded at fluted disc mounting base 2
On draw beam 4；Divide fluted disc through involute teeth 301 mutually engageable in together；When 4 angle of draw beam is adjusted, then through fluted disc
Clamping screw 30 is locked.
Rotary shaft 5 is made of the axle sleeve 51 of the front end of two draw beams 4 and the attachment pegs 52 being fixed in traction crossbeam 6；Axis
Set 51 and 52 clearance fit of attachment pegs, rotary shaft caging bolt 8 and rotation axle lock nut 7 are axial to axle sleeve 51 and attachment pegs 52
Limit, such rotary shaft 5 cannot move axially, and can only radial rotating.
Referring to Fig. 3, three fluted disc clamping screws 30 are solid after being intermeshed the involute teeth 301 for dividing fluted disc being split into two halves
It is scheduled on together.
Referring to involute fluted disc in this figure of Fig. 3 be equipped with for engagement involute teeth 301, fluted disc be equipped with for across
Three equally distributed annular rings of fluted disc clamping screw 30, fluted disc clamping screw 30 can be mobile around ring in annular ring aperture, this
Just draw beam regulates angle to sample prescription, that is, can carry out high fine-tuning to front and back crossbeam to draw beam.
Fig. 4 is the A-A view of the involute teeth 301 of Fig. 3.
Fig. 5 is the structure chart of rotary shaft 5, and rotary shaft 5 is made of the axle sleeve 51 and attachment pegs 52 of 4 front end of draw beam；Axle sleeve
51 and 52 clearance fit of attachment pegs, it rotates axle lock nut 7 and rotary shaft caging bolt cooperates and joining the limit of axle sleeve 51
In outbound 52；The other end of attachment pegs 52 is fixed in traction crossbeam 6.
In machine walking at rough road surface, attachment pegs 52 pass through and 51 clearance fit of axle sleeve, rotate shaft locking
After nut 7 and the mutual cooperation of rotary shaft caging bolt limit axle sleeve 51, prevent axle sleeve 51 from moving axially, it can only be radial
Rotation, to achieve the purpose that baler and tractor traveling are non-interference in broken terrain.
