Flat axle fracture, such agricultural machinery just need repairing, shorten using the time, and have delayed the work time.
Summary of the invention
The solved the technical problems existing in the prior art of the utility model are that blade and trunnion axis are rigidly connected, and are being encountered
It when obstruction, is easy stress and blade is knocked into damage or the problem of by horizontal axle fracture, a kind of flexible connection is provided and has imitative
The rake group of shape function.
The utility model is that technical solution used by solving its technical problem is:
A kind of rake group with profile modeling function is by multiple fastener proper alignments with blade and to be connected to level
The rake group structure formed on axis, the trunnion axis are connect by vertically disposed supporting beam with crossbeam, and the supporting beam is arc
Thick steel plate structure, the crossbeam and the trunnion axis are parallel to each other and isometric, and the center of crossbeam is connect with girder, and is led to
It crosses girder and entire rake group is connected to rear tractor, and blade is made to contact soil.
Further, the end of the trunnion axis forms beam-ends edge, and the cross section of trunnion axis is in the hollow knot of crosswise
Structure.
Preferably, the beam-ends edge is square baffle structure.
Further, the fastener includes two half square frameworks, the two half square frameworks pass through mutual corresponding company
It is bolted after lug pairing, to form a square hollow tubular structure.
Preferably, locking ear, the bolt quantity are locked and formed on each pair of engaging lug by several bolts
No less than two.
Further, four isometric elastic polyurethane columns are set on four angles of the square hollow tubular structure, together
When this four elastic polyurethane columns be also located in the recessed position of crosswise hollow structure of trunnion axis.
Further, relative position is also welded in that half square framework of lower section in two half square frameworks
Raking arm, the raking arm are thick steel plate structure, and blade is arranged in end, and the blade is connect by connecting shaft with the pole-climbing.
Possessed beneficial effect is the utility model compared with prior art: fastener and trunnion axis in the utility model
Junction setting elasticity elastic polyurethane column so that between fastener and trunnion axis formed flexible connection, avoid they
It when rigid connection, is hindered, generates stress, so that the problem that connecting portion or stressed member are damaged, has larger on ground
When stone or tree root, rake group stress is larger to be bounced, protection blade it is not damaged, and rake group can be risen and fallen according to ground shape into
Row floats, so that tilling depth be kept to stablize.

Specific embodiment
The present invention is described in further detail below with reference to embodiment, embodiments of the present invention are not limited thereto.
As shown in Figure 1 and 2, a kind of rake group with profile modeling function is neat by multiple fasteners 5 with blade 11
The rake group structure formed on trunnion axis 4 is arranged and is connected to, the trunnion axis 4 is connected by vertically disposed supporting beam 3 with crossbeam 2
It connects, the end of the trunnion axis 4 forms beam-ends edge 6, and the beam-ends edge 6 is square baffle structure, for limiting fastening
The position of part 5 is to prevent fastener 5 to be sliding out trunnion axis 4, and the cross section of trunnion axis 4 is in crosswise hollow structure, institute
Stating supporting beam 3 is arc thick steel plate structure, and the crossbeam 2 and the trunnion axis 4 are parallel to each other and isometric, and in crossbeam 2
The heart is connect with girder 1, and entire rake group is connected to rear tractor by girder 1, and blade 11 is made to contact soil.
As shown in Fig. 2 ~ 3, the fastener 5 includes two half square frameworks 12, the two half square frameworks include two
A engaging lug, the two engaging lugs are that the two sides on single half square framework length direction are connected along first be configured
Ear 13 and the second engaging lug 14, the two half square frameworks are bolted after being matched by mutual corresponding engaging lug, often
To being locked by several bolts 15 on engaging lug and forming locking ear 8, the quantity of the bolt 15 is no less than two,
To form a square hollow tubular structure, set on four angles of this square hollow tubular structure four it is isometric
