Description

Pull farm machinery three-point hitch
Technical field
The utility model relates to agricultural mechanical field, particularly a kind of use on agricultural machinery pull farm machinery three-point hitch.
Background technology
Agricultural machinery generally adopts hitch to hang pulls farm machinery and carries out farming, controls various diverse location of pulling farm machinery by the lifting of hitch.At present, the suspension arm rotating shaft of hanging machinery is all directly be welded in frame, and suspension arm is around suspension arm axis of rotation, and it is solid that this just makes suspension arm rotating shaft use, and not only increases overall weight, also easy flexural deformation.Owing to pulling farm machinery Heavy Weight, in main frame walking and operation process, often swing, a larger side force will be created, make suspension arm bending.In order to overcome this side force, just need increase the thickness of suspension arm, gaining in weight.The connecting hole of suspension arm and lifting chain is a weak spot on suspension arm, during using in the past, occurs the phenomenon of the lifting chain fracture of more connection hole cracking or connection hole, and therefore also needs the bonding strength strengthening connection hole.Next is that lifting chain and Anchoring chain can not be finely tuned; The crosspiece of upper connecting rod and hanger bracket is interfered, and causes lifting chain significantly not regulate, and lift arm assembly syndeton intensity difference under Anchoring chain and left and right, easily breaks.For this reason, many manufacturers and knowledgeable people develop and develop, but market not yet have so far comparatively satisfied product come out.
Summary of the invention
For overcoming the problems referred to above existing for existing farm machinery hitch, the purpose of this utility model be to provide a kind of simple and reasonable, flexible operation is light, lightweight, use reliable and stable, install and easy to adjust pull farm machinery three-point hitch.
The utility model solves the problems of the technologies described above adopted technical scheme, it comprises frame, be fixed on the left-right rotation seat in frame, upper suspension assembly, described upper suspension assembly comprises suspension arm rotating shaft, lift arm on left and right, crosspiece, on left and right, lift arm correspondence is fixed on and hangs arm pivoted two ends, crosspiece correspondence is fixed between the upper lift arm in left and right, suspension arm rotating shaft is arranged on left-right rotation seat rotationally, lift cylinder is hinged with between frame and crosspiece, the both sides correspondence of frame lower is hinged with the lower lift arm in left and right, the corresponding left and right raising rod assembly that is connected with between lift arm with lift arm on left and right under left and right, crosspiece is hinged with adjusting yoke, lift arm suspension joint on the lower lift arm in left and right and the pull bar suspension joint composition trifilar suspension structure on upper adjusting yoke are used for hanging dilatory farm machinery.
The further scheme of the utility model, the centre position of described frame lower is fixed with chain stays, correspondingly between lift arm with chain stays under left and right is connected with left and right Anchoring chain assembly.
The further scheme of the utility model, correspondingly between lift arm with both sides before and after crosspiece on described left and right is fixed with stiffener, and in suspension arm rotating shaft, left and right, lift arm, crosspiece and stiffener form stable isosceles trapezoidal structure.
The further scheme of the utility model, described left and right raising rod assembly is formed by connecting by adjusting rod and chain joint.
The further scheme of the utility model, described left and right Anchoring chain assembly is formed by connecting by chain joint, double end adjusting screw(rod) and chain type bolt successively.
The further scheme of the utility model, described left-right rotation seat is provided with for the arm pivoted pump nozzle of lubricious suspension.
After adopting said structure, compared with prior art have the following advantages and effect: one is because suspension arm rotating shaft is arranged on on rotation seat in frame rotationally, suspension arm rotating shaft can adopt hollow-core construction, in suspension arm rotating shaft, left and right, lift arm, crosspiece and stiffener interfix and form stable isosceles trapezoidal structure, upper adjusting yoke is hinged on crosspiece, upper adjusting yoke and crosspiece are not interfered mutually, left and right raising rod assembly can significantly regulate, structure is simple, flexible operation, easy to adjust, use reliable and stable.Two is be connected with left and right Anchoring chain assembly due to corresponding between lift arm and the chain stays of frame under left and right, and left and right is fixed with stiffener between lift arm and crosspiece, makes loop strength distribute rationally, can swing by spacing mounted equipment in walking process.Three is can adjust the angle of penetration of farm machinery by regulating upper adjusting yoke length, can by embedded depth and the degree of balance regulating left and right raising rod assembly length to adjust farm machinery, bonding strength can be adjusted by regulating left and right Anchoring chain assembly length, and prevent farm machinery from acutely swinging further.Four is because rotation seat is provided with pump nozzle, and not only in use procedure, coefficient of friction is little, long service life, and dismounting is simple, easy to maintenance.
