Abstract
The utility model discloses a corn harvester main transmission clutch mechanism, including a swing arm hinged on a harvester chassis longitudinal beam and a belt tension pulley in transmission connection with one end of the swing arm; an oil cylinder is mounted on the harvester chassis longitudinal beam; a driving rod is hinged on the piston rod of the oil cylinder; the other end of the swing arm is hinged on the driving rod; a section of screw threads is respectively arranged on two ends of the driving rod; a nut is respectively screwed on two sections of screw threads; two sliding disks are slidably sleeved on the driving rod between two nuts; a compression spring sleeved on the driving rod is disposed between two sliding disks; and the other end of the swing arm is hinged on the sliding disk away from the oil cylinder. The clutch mechanism is easy to operate and has less damage to the belt.
Description
Technical field
The utility model relates to a kind of maize harvesting machine main transmission clutch.
Background technology
Existing maize harvesting machine, its engine is realized power transmission to transmission of power to final drive shaft by belt, adjusts the degree of tightness realization engine of belt and the clutch of final drive shaft by regulating wheel.Regulating wheel is rotatably connected in the swing arm, and swing arm is hinged on the support that is fixed in chassis member, by manual manipulation and the hinged pull bar driving swinging arm of swing arm, to realize the clutch of main transmission.Above-mentioned clutch mainly has the following disadvantages: the one, and drive pull bar and require great effort very much, make the difficulty of controlling change of clutch, the 2nd, impact greatly during tightening belt, belt is caused very macrolesion, influence the service life of belt.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, and a kind of maize harvesting machine main transmission clutch is provided.
In order to solve above-mentioned first technical problem that deficiency is brought, the utility model provides a kind of maize harvesting machine main transmission clutch of following structure, comprise the tension pulley that is hinged on the swing arm on the reaping machine chassis member and is rotatably connected on swing arm one end, its design feature is: on the reaping machine chassis member oil cylinder is housed, be hinged with driving rod on the piston rod of oil cylinder, the other end of swing arm is hinged on the driving rod.
The maize harvesting machine main transmission clutch of said structure drives swing arm and then drives the regulating wheel action realizing the clutch of main transmission by oil cylinder, thus make clutch control being very easy to of change.
In order to solve above-mentioned second technical problem that deficiency is brought, technique scheme has been done following improvement: the two ends of described driving rod respectively are provided with one section screw thread, respectively be bolted with nut on two sections screw threads, driving rod upper sliding sleeve between two nuts has two slider disc, be provided with the stage clip that is sleeved on the driving rod between two slider disc, the other end of swing arm is hinged on the slider disc away from oil cylinder.
In the technique scheme,, make that the enormous impact that produces when tension pulley contacts with belt is slowed down effectively by this elastomeric element of stage clip, make and reduce greatly because of impacting the damage that belt is caused owing to increased this elastomeric element of stage clip.
Advantage of the present utility model is to control easily, damages little to belt.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Maize harvesting machine main transmission clutch as depicted in figs. 1 and 2 comprises swing arm 1, tension pulley 2 and reaping machine chassis member 8.Be hinged with oil cylinder 3 on the reaping machine chassis member 8 and be connected with swing arm support 9.Be hinged with driving rod 4 on the piston rod of oil cylinder 3, the two ends of driving rod 4 respectively are provided with one section screw thread, respectively being bolted with driving rod 4 upper sliding sleeves between nut 5, two nuts 5 on two sections screw threads has between two slider disc, 6, two slider disc 6 and is provided with the stage clip 7 that is sleeved on the driving rod 4.Swing arm 1 is made of short section and long section, a short section and the interconnection of long section be "
" shape, swing arm 1 is hinged on the swing arm support 9 by junction of its short section and long section, and tension pulley 2 is rotatably connected on the end of the short section of swing arm 1, and the end of the long section of swing arm 1 is hinged on the slider disc 6 away from oil cylinder 3.The pretightning force that can regulate stage clip 7 by the distance of adjusting 5 on two nuts.Oil cylinder 3 promotion swing arms 1 drive tension pulley 2 compresses or unclamps main drive belt 10, realizes the clutch of engine belt wheel 11 and final drive shaft belt wheel 12.In the above-mentioned relevant description that is articulated and connected, hinged implementation is a known technology, does not repeat them here.
