Abstract
The utility model discloses a maize picker gear directly links mechanism. This maize picker gear directly links mechanism, including gear control hinge pole, the lower extreme of gear control hinge pole is articulated mutually with the one end of first adjustable connecting rod, the other end of first adjustable connecting rod is articulated with pitman arm's one end, pitman arm's middle part is rotated with the single -revolution axle and is linked to each other, pitman arm's the other end is articulated mutually with the one end of the adjustable connecting rod of second, the other end of the adjustable connecting rod of second is articulated mutually with the one end of an eave tile pull rod, the other end of eave tile pull rod links to each other with gearbox box shift fork through a split pin. This maize picker gear directly links mechanism, the tip of first adjustable connecting rod, the adjustable connecting rod of second are processed into left right -handed thread, the basis of not disassembling go up through with be connected the relative rotation pitched and to neutral gear and stroke individual adjustment, avoid revising repeatedly. When shifting or pluck the neutral gear, power transmits gearbox box shift fork through the pitman arm switching -over, realizes the gear separation or combines.
Description
Technical field
The utility model belongs to mechanical field, the direct-connected mechanism of more particularly to a kind of maize harvesting machine gear.
Background technology
At present, the mostly of Miniature corn harvesting machine tool employing on domestic market are flexible axle shift position control mechanisms, are that guarantee is changed
Gear smooth-going, flexible shaft mechanism is by ball pivot, pull bar, guide pipe, heart yearn, outer tube, clamping sleeve, oscillating bearing, packing ring, thin nut, support
Deng part composition.Traditional this shift position control mechanism can cause the overall structure of corn harvesting machine gear control system to answer
It is miscellaneous, and cost of manufacture is high.Secondly as system parts are more, also bring along to operations such as assembling, maintenance, debugging gears
Very big workload.Again, in use, it is easily dead by foreign matters from being blocked or rust between heart yearn and outer tube, cause gear
Connect, pluck gear difficulty or failure, affect the performance of maize harvesting machine.Therefore, a kind of simple structure, reliability are invented, can
Realize gear control function and installation, verification, to keep in repair all convenient maize harvesting machine position control mechanism very necessary.
The content of the invention
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of simple structure, it is reasonable in design, corn receive
The direct-connected mechanism of machine gear is obtained, problems of the prior art are solved.
The utility model is achieved by the following technical solution：
A kind of direct-connected mechanism of maize harvesting machine gear, including gear control toggle, the lower end of gear control toggle and the
One end of one adjustable link is hinged, and the other end of the first adjustable link is hinged with one end of the pitman arm of bending,
The middle part of pitman arm is rotatedly connected with single-revolution axle, and the other end of pitman arm mutually cuts with scissors with one end of the second adjustable link
Connect, the other end of the second adjustable link is hinged with one end of an eave tile pull bar, the other end of eave tile pull bar is by an opening
Pin is connected with gear box shift fork.
Packing ring is provided with the junction of split pin and eave tile pull bar.
The quantity of the pitman arm is two groups or more.
First compensation linkage and the second compensation linkage are to be the pull bar that end thread is arranged with connection fork.
The beneficial effects of the utility model are：The direct-connected mechanism of maize harvesting machine gear, the first adjustable link, second can
Adjust connecting rod end be processed into left-right rotary screw thread respectively, can on the basis of not disassembling by be connected pitch rotate against
Neutral and stroke adjusted respectively, it is to avoid correct repeatedly.When being shifted gears or being plucked neutral, the diverted rocking arm commutation of power is passed
Gear box shift fork is delivered to, realizes that gear is separated or combined, simple structure is easy to adjust, low manufacture cost, to assembling, dimension
Repair, to debug gear simple, and be not easy to occur dead by foreign matters from being blocked or rust between heart yearn and outer tube, cause gear connection, pluck
Gear is difficult or fails, and affects the phenomenon of the performance of maize harvesting machine.
Description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment 1.
In figure, 1, gear control toggle, the 2, first adjustable link, 3, pitman arm, 4, gyroaxis, 5, second can adjust
Connecting rod, 6, eave tile pull bar, 7, split pin, 8, gear box shift fork, 9, packing ring, 10, connection fork.
Specific embodiment
Clearly to illustrate the technical characterstic of this programme, below by specific embodiment, and with reference to its accompanying drawing, to this reality
It is described in detail with new.
Embodiment：
As shown in fig. 1, the embodiment includes that a gear controls toggle 1, and the lower end of gear control toggle 1 is adjustable with first
One end of section connecting rod 2 is hinged, and the other end of the first adjustable link 2 is hinged with one end of the pitman arm 3 of bending, turns to
The middle part of rocking arm 3 is rotatedly connected with single-revolution axle 4, and the other end of pitman arm 3 mutually cuts with scissors with one end of the second adjustable link 5
Connect, the other end of the second adjustable link 5 is hinged with one end of an eave tile pull bar 6, the other end of eave tile pull bar 6 is opened by one
Mouth pin 7 is connected with gear box shift fork 8.
Packing ring 9 is provided with the junction of split pin 7 and eave tile pull bar.
The quantity of the pitman arm 3 is two groups or more.
The compensation linkage 4 of first compensation linkage 2 and second is arranged with the pull bar of connection fork 10 for end thread.
