Description

Small harvester operating mechanism

Technical field

The utility model relates to a kind of farm machinery, is specifically related to small harvester operating mechanism.

Background technology

Existing rice harvester is in order to adapt to the comparatively severe terrain environment in mountain region, need to grain header be done small and exquisitely and durable, and can make operating personnel drive easily grain header, for large-scale grain header, generally driver's seat and operating mechanism platform can be set specially, but for miniature agricultural machinery, in order to reduce the weight and volume of agricultural machinery, must carry out rational layout to driver's seat and console, it is less for agricultural machinery is realized, conventional way is by longer handrail, manipulation device is set on handrail, but strengthened like this operation easier of people to grain header, and operator also will directly walk in field, in order to make operator avoid the operation of walking in field, rear-mounted driver's seat is set on miniature agricultural machine, make driver's seat not occupy the space of large of grain header, on driver's seat, by operating mechanism, grain header is gathered in, turn to the control with speed change, tradition is because needs are artificially stood control crank is operated in field, for being all conveniently adopts handle to drive span wire system to regulate, once but when taking driver's seat to operate, re-using bracing wire controls, very easily after people loses center of gravity, cause out of control, for the driver who is sitting on small harvester, an operating mechanism that is simply easy to control is necessary.

Summary of the invention

The purpose of this utility model is to provide a kind of convenience, simple and central controlled small harvester operating mechanism.

To achieve these goals, the technical scheme that the application proposes is, small harvester operating mechanism, comprise guidance panel, the bracing frame of support operation panel, throttle control and control stick, described guidance panel is provided with the loose slot that four stripe pitch are equal, on bracing frame, be provided with transverse axis, centered by the above transverse axis of guidance panel, axle is in the arc-shaped, described control stick comprises walking control stick, ceding of Taiwan control stick and a left side, right turn control stick, walking control stick, ceding of Taiwan control stick is by clutch axle sleeve and be connected to upper transverse axis both sides, clutch axle sleeve rotates around upper transverse axis, left, right turn control stick is connected to the centre of upper transverse axis by steering column jacket, walking control stick puts to be also provided with ceding of Taiwan control stick and clutch shaft and makes to walk the control stick jointed shaft vertical with clutch axle sleeve rotation direction with ceding of Taiwan control stick, walking control stick, ceding of Taiwan control stick is placed in the loose slot of guidance panel both sides, a described left side, right turn control stick is placed in two of the centres loose slot on guidance panel, the guidance panel at two loose slot places, described centre is partly set to depression or outstanding structure, the draw-in groove communicating with this loose slot is set on the loose slot of described guidance panel both sides, on the axle sleeve at described every one control lever place, be all fixedly connected with transmission ear, the transmission ear of upper transverse axis is connected by positive drive bar with the transmission ear of lower transverse axis, guidance panel is provided with integral type handrail near driver's seat one side and guidance panel both sides.

The advantage of the utility model console is: when small harvester enters hilly country and carries out farm work, operating personnel are directly sitting on driver's seat, the turning to, accelerate, stopping controlling small harvester by four one control levers; 1, due to walking control stick and ceding of Taiwan control stick are arranged in the movable span on both sides, its objective is that control stick need to realize transverse movement, be arranged in both sides and can prevent the interference between control stick; 2, walking control stick and ceding of Taiwan control stick are respectively to control Traction clutch and ceding of Taiwan clutch, for realizing the not flame-out grain header that stops, now by also coordinating the control stick jointed shaft vertical with axle sleeve rotation direction with ceding of Taiwan control stick that make to walk in the draw-in groove of guidance panel, operating personnel just can keep the state of action bars always by draw-in groove, reach the object simplifying the operation; 3, on the axle sleeve at described every one control lever place, be all fixedly connected with transmission ear, the transmission ear of upper transverse axis is connected by positive drive bar with the transmission ear of lower transverse axis, by hard drive link, the power of action bars is delivered to impetus, before comparing, use and there is flexible bracing wire and carry out power transmission, the loss of energy in the transmittance process greatly reducing; 4, guidance panel near driver's seat on one side and guidance panel both sides be provided with integral type handrail, because most place, field belongs to level land, when grain header is advanced in field, the most of the time only need maintain self in the process of walking stable by handrail.

Further, because control stick is to rotate around upper transverse axis, more in order to prevent that the body of rod of control stick from exposing guidance panel, described guidance panel is arc, the central point that arc is corresponding is upper transverse axis, so both guaranteed the attractive in appearance of guidance panel, and the distance that control stick exposes outside guidance panel is constant all the time.

Further, between described guidance panel and bracing frame, be provided with reinforcing tripod, by tripod, the guidance panel of arc reinforced, increased guidance panel weight capacity, guaranteed that guidance panel is not yielding.

Further, the corresponding axle sleeve of described left steering control stick is enclosed within on the axle sleeve that right control stick is corresponding or the corresponding axle sleeve of right turn control stick is enclosed within on the axle sleeve that left control stick is corresponding, so just can when saving top rail shaft length, guarantee power transmission process, drive disk assembly does not interfere.

Further, described accelerator control device is arranged on the right side of described handrail, and convenient operation person carries out the size adjustment of throttle at any time like this.

Further, on one side described guidance panel is provided with illuminating lamp away from driver's seat, when illuminating lamp is installed, make 1 meter of the shadow surface radiation grain header front end of light, make grain header also can realize operation in the darker environment of light.

Further, support frame as described above and grain header removably connect by inserted link fitted bolt and grain header, and bracing frame is that many inserted links coordinate the spud pile on grain header, then by bolt, is undertaken fastening; After time can have been assembled guidance panel so when mounted, be connected on grain header, make can separately assemble at each assembly of production process.

Finally, described guidance panel also comprises the vertical panel near one side of driver's seat, is provided with and controls illuminating lamp and starting switch on described vertical panel.Because vertical panel and guidance panel are in coplanar not, increased the installed surface of operating platform.
