Description
Technical field
The utility model relates to a kind of agricultural tool, especially relates to a kind of rotovator.
Background technology
Existing rotovator generally is arranged on the rear of dynamic power machine with symmetric mode, evenly be provided with about the rotovator framework, dynamic power machine applies pulling force to framework the place ahead central authorities, pulling force acts on the main-gear box by universal joint, and then act on an auxiliary transmission that is arranged on an end by universal joint, subsequently with transmission of power to power transmission shaft, the power of framework pulling force and power transmission shaft transmission orders about the rotary tillage cutter and finishes the rotary tillage operation.But utility model inventor finds existing rotovator and has following problems at least: the rotary tillage cutter is arranged on the dead astern of dynamic power machine, in the place that barrier rotary tillage machineries such as running into fruit tree can not arrive, the rotary tillage cutter correspondingly can't be carried out the rotary tillage operation, setting inferior place just can not be by rotary tillage, and the rotovator job area is restricted.
In view of this, the present utility model people is active development research, and for improving the deficiency of the said goods, through the permanent research and experiment of making great efforts, development and Design goes out multifunction rotavator of the present utility model finally.
The utility model content
The technical problems to be solved in the utility model provides a kind of multifunction rotavator, can solve the problem that rotovator rotary tillage cutter can't arrive at a distance in the prior art, job area is subject to the barrier restriction, scope is little.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multifunction rotavator, comprise the rotovator framework, main-gear box, auxiliary transmission, power transmission shaft and rotary tillage cutter, be provided with first universal joint before the described main-gear box, described auxiliary transmission is arranged at a side end of rotovator framework, its upper end links to each other with main-gear box by second universal joint, the lower end links to each other with the power transmission shaft that is arranged at the framework below by the 3rd universal joint, described power transmission shaft links to each other with described rotary tillage cutter, described power transmission shaft is the expansion link power transmission shaft, the end side of described rotovator framework links to each other with other positions of rotovator framework by first expansion link, second expansion link is set on main-gear box to link to each other with the described end side of rotovator framework, also be provided with distributor and oil cylinder on the described rotovator, described distributor links to each other by connecting line with described oil cylinder.
Preferably, the end side of described rotovator framework below is provided with driving wheel.
Preferably, the end side of described rotovator framework is outside equipped with directive wheel.
Preferably, described directive wheel and the connected mode of described framework are for to be connected by movable frame.
After adopting the technical solution of the utility model, because described power transmission shaft is the expansion link power transmission shaft, the end side of described rotovator framework links to each other with other positions of rotovator framework by first expansion link, second expansion link is set on main-gear box to link to each other with the described end side of rotovator framework, also be provided with distributor and oil cylinder on the described rotovator, described distributor closes described oil cylinder and links to each other by connecting line, therefore, can order about first expansion link by oil cylinder and distributor distributed power, second expansion link and expansion link power transmission shaft generation stretching motion, and then it is flexible to drive the rotary tillage cutter, can not arrive the still effect of rotary tillage operation of zone to reach to dynamic power machine one side.Adopt this unique design, make the utility model product contrast prior art, can reach the barrier zone that can't arrive and carry out rotary tillage, widen the practical improvement of the rotovator scope of application dynamic power machine.
Description of drawings
Fig. 1 is the side schematic view of a kind of rotovator in the prior art.
Fig. 2 is the structural representation of the utility model multifunction rotavator.
Embodiment
Below in conjunction with drawings and embodiments the utility model is described in further detail.
See also Fig. 1, Fig. 1 is the side schematic view of a kind of rotovator in the prior art, it comprises the first half bracket and the major and minor gearbox of part frame, dynamic power machine is connected with bracket, and then the pulling force of exerting pressure, evenly be provided with about the rotovator framework, pulling force acts on the main-gear box by universal joint, and then act on an auxiliary transmission that is arranged on an end by universal joint, subsequently with transmission of power to power transmission shaft, the power of framework pulling force and power transmission shaft transmission orders about the rotary tillage cutter and finishes the rotary tillage operation.
Consult Fig. 2, structural representation for the utility model multifunction rotavator, a kind of multifunction rotavator, comprise the rotovator framework, main-gear box 3, auxiliary transmission 5, power transmission shaft 16 and rotary tillage cutter 7, be provided with first universal joint 2 before the described main-gear box 3, can be connected with the power output source 1 of hitching machinery by first universal joint 2, described auxiliary transmission 5 is arranged at a side end of rotovator framework, its upper end links to each other with main-gear box 3 by second universal joint 4, the lower end links to each other with the power transmission shaft that is arranged at the framework below by the 3rd universal joint 6, for affiliated rotary tillage cutter 7 provides power, described power transmission shaft 16 links to each other with described rotary tillage cutter 7, described power transmission shaft 16 is the expansion link power transmission shaft, level is flexible under external force, and traction rotary tillage cutter 7 left and right horizontal move, the end side of described rotovator framework links to each other with other positions of rotovator framework by first expansion link 13, second expansion link 12 is set on main-gear box 3 to link to each other with the described end side of rotovator framework, also be provided with distributor 8 and oil cylinder 10 on the described rotovator, described distributor 8 and described oil cylinder 10 link to each other by connecting line (9,11).Like this, if make rotary tillage cutter 7 to a lateral movement to reach elongation state, can be under the acting in conjunction of oil cylinder 10 and distributor 8, second expansion link 12 extends to a lateral movement, correspondingly first expansion link 13 and expansion link power transmission shaft are to the same side motion extension, the drive of rotary tillage cutter is extended to outside far-end, and the rotary tillage cutter promptly departs from the rotovator middle position, can implement rotary tillage to the soil of a side.
