Abstract
The utility model belongs to the field of vehicles, and relates to a multifunctional special-purpose vehicle three-link hitch which is provided with a multifunctional special-purpose vehicle and characterized in that an installation support is connected with a left longitudinal beam and a right longitudinal beam of an upper frame of the multifunctional special-purpose vehicle in a linkage mode, and a lifting revolving shaft is mounted on the top of the installation support through two revolving shaft bearing seats on the installation support; a lifting power arm, a left lifting arm and a right lifting arm are arranged on the lifting revolving shaft in linkage connection mode; one ends of a left lifting draw bar and a right lifting draw bar are hinged with the left lifting arm and the right lifting arm; the other ends of the left lifting draw bar and the right lifting draw bar are hinged with a left lower link and a right lower link; a cylinder body of a hydro-cylinder is hinged with a hydro-cylinder supporting seat; the upper end of a hydro-cylinder piston rod is hinged with the lifting power arm on the lifting revolving shaft; one end of an upper link is hinged with an upper link supporting seat of the lifting revolving shaft; one end of the lower link is hinged with a cargo compartment rear bearing shaft sleeve; the other end of the upper link and the other end of the lower link are respectively hinged with a supporting seat of a work machine. When the multifunctional special-purpose vehicle three-link hitch is not used, the overall three-link hitch can be dismantled, an original cargo compartment overturning double-acting cylinder is used as a lifting power cylinder, so that a hydraulic system structure is simplified, and manufacture cost is reduced.
Description
Technical field
The utility model relates to vehicular field, at length says it is a kind of Multifunctional vehicle special rearmounted three-point linkage.
Background technology
As everyone knows, tractor generally connects by complicated rearmounted three-point linkage and numerous farm machinery, thereby realizes the multifunctional farm implements operation.And Multifunctional vehicle special is difficult to install rearmounted three-point linkage because structure is limit, the requirement that be difficult to satisfy farming, herd, the forest farm is suspended on Work machine to numerous needs the Multifunctional vehicle special front portion.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Multifunctional vehicle special rearmounted three-point linkage, can link with the Multifunctional vehicle special rear portion easily, thereby realize placing the Multifunctional vehicle special rear portion to carry out the purpose of operation Work machine.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Multifunctional vehicle special rearmounted three-point linkage, be provided with Multifunctional vehicle special, it is characterized in that, mounting bracket connects with the added left-right longeron of Multifunctional vehicle special, promote rotating shaft is installed in mounting bracket by two shaft bearing seats on the mounting bracket top, promote power arm and about two lift arms be connected in and promote in the rotating shaft, about two raising rod one ends and lift arm hinged, the raising rod other end with about two lower links be hinged, cylinder block and cylinder support are hinged, the upper end of cylinder piston rod is hinged with the lifting power arm that promotes in the rotating shaft, one end of upper connecting rod is hinged with the upper connecting rod bearing that promotes in the rotating shaft, lower link one end and loading space rear support axle sleeve are hinged, and the other end of upper connecting rod and lower link is hinged with the bearing of Work machine respectively.
The beneficial effects of the utility model are, but have designed a kind of mounting bracket of novel integral demounting, and the time spent can whole not remove trifilar suspension, and used the former loading space two-way cylinder of tumbling, as promoting actuator cylinder, simplified hydraulic system structure, thus the manufacturing cost that reduces.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among Fig. 11, Multifunctional vehicle special, 2, cylinder support, 3, cylinder block, 4, cylinder piston rod, 5, promote power arm, 6, mounting bracket, 7, support construction bolt hole, 8, lift arm, 9, shaft bearing seat, 10, promote rotating shaft, 11, shackle bracket behind the leaf spring, 12, loading space rear support axle sleeve, 13, the upper connecting rod bearing, 14, raising rod, 15, lower link, 16, upper connecting rod, 17, Work machine.
Embodiment
In Fig. 1, the utility model is provided with Multifunctional vehicle special 1, and mounting bracket 6 connects with the added left-right longeron of Multifunctional vehicle special 1 by bolt, support construction bolt hole 7.To promote rotating shaft 10 and be installed in by two shaft bearing seats 9 on the mounting bracket 6 top of mounting bracket 6, to promote power arm 5 and about two lift arms 8 promoting in the rotating shaft 10 by spline or key connecting, left and right sides raising rod 14 1 ends and lift arm 8 are hinged by bearing pin, raising rod 14 other ends with about two lower links 15 be hinged by bearing pin, cylinder support 2 on double-action hydraulic lift cylinder cylinder body 3 and the vehicle frame is hinged by bearing pin, the upper end of hydraulic cylinder piston rod 4 is hinged with the lifting power arm 5 that promotes in the rotating shaft 10, one end of the upper connecting rod 16 of trifilar suspension is hinged with the upper connecting rod bearing 13 that promotes in the rotating shaft 10, about two lower link 15 1 ends be hinged by bearing pin with loading space rear support axle sleeve 12 respectively, loading space rear support axle sleeve 12 is fixed on behind the leaf spring on the shackle bracket 11, the other end of upper connecting rod 16 and left and right sides lower link 15 is hinged with Work machine 17 corresponding bearings respectively, when cylinder piston rod 4 is in when ejecting the position, Work machine 17 lands and can carry out operation, when operation machinery 17 need to lift, cylinder piston rod 4 is retracted, drive lifting power arm 5 is done and is rotated counterclockwise, drive lifting rotating shaft 10 is done and is rotated counterclockwise, promote rotating shaft 10 and drive again 8 rotations of left and right sides lift arm, lift arm 8 drives left and right sides raising rod 14 and moves upward together, thereby two lower links 15 move upward together about driving, left and right sides lower link 15 drives Work machine 17 again and upwards lifts, thereby realizes the Work machine built on stilts.
Pull down each attachment pegs, the disassembling bolts with on mounting bracket 6 and the longitudinal beam can realize the rearmounted three-point linkage overall pulling down.
