The object of the present invention is achieved like this: a kind of towed double-pole mower, it comprises frame, grass-mowing, transmission mechanism and Griffe mechanism, it is characterized in that: anterior small frame and rear portion big frame that described frame is alignd by inner side edge form, the front end inner side of small frame arranges traction seat, traction seat front end connects traction pawl by bearing pin, traction seat arranges intermeshing end-tooth with the connecting end surface of traction pawl, and road wheel is installed in the both sides, rear portion of big frame; Described grass-mowing comprises internal cutter and external cutter, and the medial extremity of internal cutter is arranged on the outside of small frame by knife rest, and the medial extremity of external cutter is arranged on the outside of big frame by knife rest; Described transmission mechanism comprises a longitudinal rack-mounted final drive shaft, and final drive shaft drives internal cutter and external cutter shearing work by the belt gear of internal cutter and the belt gear of external cutter respectively.
Further, described Griffe mechanism comprises internal cutter Griffe mechanism and external cutter Griffe mechanism, and internal cutter Griffe mechanism and external cutter Griffe mechanism are all by hydraulic jack and griffe connecting rod and form.
Further, the belt gear of described internal cutter is by main pulley, form from belt pulley, regulating wheel, crank and connecting rod.
Further, the belt gear of described external cutter is by main pulley, form from belt pulley, pinch wheels, regulating wheel, crank and connecting rod.
Further, in the inner side of big frame, wide heterotype steel plate is set, in the narrow heterotype steel plate of arranged outside of big frame.
Advantage of the present invention is:
1) it comprises internal cutter and external cutter, has increased cutting operation fabric width, has improved operating efficiency, has reduced motor vehicle and has rolled grassland density, is conducive to protect grassland.
2) frame consists of anterior small frame and rear portion big frame, rational in infrastructure, simply compact, is conducive to reduce production costs, and reduces after-sales maintenance service.
3) traction seat front end connects traction pawl by bearing pin, traction seat arranges intermeshing end-tooth with the connecting end surface of traction pawl, by end-tooth, can adjust the fixed angle between traction seat and traction pawl, adapt to the needs of the different traction hights of different traction locomotives, the suitable mowing height of external cutter in guaranteeing.
4) described transmission mechanism drives the belt gear of internal cutter and the belt gear of external cutter to drive internal cutter and external cutter shearing work by a final drive shaft, transmission mechanism is rational in infrastructure, stable and reliable operation, has overcome gear-box that prior art generally adopts and transmission shaft driven complex structure, cost is high and parts often damage shortcoming.
5) in inner side and the outside of big frame, be provided with respectively wide heterotype steel plate and narrow heterotype steel plate, this design, when having guaranteed support strength, reduces steel weight; Appearance and modeling is also very attractive in appearance, and trade mark advertisement content can be set in the above.
6) adopt the Griffe mechanism that hydraulic jack is power, there is the advantages such as simple in structure, stable performance, manipulation convenience.
