Description
Technical field
The utility model relates to a kind of lower cutter device of agro-farming mechanical field, particularly grain header.
Background technology
Grain header is a kind of conventional machinery gathering in the cereal such as paddy, the wheat head, in the middle of modern agricultural production, is extensively promoted the use of.The lower cutter of traditional grain header and harvester running gear be public power set to provide power, as long as start grain header, in the process of walking, the movable blades in lower cutter will move back and forth grain header always in the horizontal direction.And in the process of walking, hard material can be run into unavoidably, as stone etc., therefore, movable blades, after meeting these hard objects, is easy to movable blades to damage.In addition, because blade is consumptive material, and existing grain header upon actuation its movable blades will move always, produce with ledger-plate and rub, can directly shortening blade service life.
Summary of the invention
The purpose of this utility model is that the lower cutter in order to solve existing grain header starts in the process of walking always, easily damages, the problem that service life is low, and the lower cutter device of a kind of grain header provided.
To achieve these goals, the lower cutter device of the grain header designed by the utility model, it comprises frame and is arranged on movable blades and the ledger-plate of frame lower end, be arranged on the power input shaft of frame upper end, it is characterized in that, also be provided with the output shaft of shifting fork mechanism, output shaft stirs lower transverse shifting at shifting fork mechanism, combines or be separated with power shaft; Output shaft arranges eccentric wheel, eccentric wheel is connected with push rod, the other end of push rod is connected with one end of rocking arm, and the middle part of rocking arm is movably arranged on frame lower end, phase clamping in the middle part of the other end of rocking arm and movable blades; After eccentric wheel rotates, drive push rod to swing up and down, thus drive rocking arm to swing, drive movable blades left and right on ledger-plate to move back and forth.
Further, described shifting fork mechanism comprise be enclosed within respectively power shaft with on output shaft and with clutch tooth dynamic combination wheel and quiet combination wheel and be vertically fixed on dynamic combine wheel upper and for control dynamic combine to take turns take turns with quiet combination the shift fork combining or be separated, described shift fork is connected with the clutch cable of grain header.During use, pull shift fork by drag-line, make shift fork drive dynamic combination wheel to take turns with quiet combination and engage or be separated.
Further, described eccentric wheel is provided with a sleeve socket-connected with output shaft near the side of output shaft, and eccentric wheel is provided with one for installing the projection of Connection Block near the side of push rod; One is provided with for connecting push rod and eccentric Connection Block above push rod, Connection Block is provided with an installing hole matched with projection, one is provided with for clamping and fixing the breach of push rod upper end in the lower end of Connection Block, described push rod upper end is stuck in the breach of Connection Block lower end, and runs through push rod by one and be connected with the axle rotary type of Connection Block.Output shaft is connected with eccentric wheel in cam mechanism, when moving, after output shaft rotation, namely can drive and being attached thereto the eccentric wheel connect and circling.After eccentric wheel rotates, the Connection Block be fixedly connected with eccentric wheel, be connected to push rod on Connection Block will thereupon together with move, because push rod is vertically arranged, and circle around eccentric wheel, when following eccentric wheel and rotating to peak, push rod is at higher position, when wobbler action is to lowest part, push rod produces corresponding displacement thereupon, thus in wobbler action process, push rod vertical direction namely can be reciprocal move up and down, and then drive the rocking arm transverse shifting that is connected of push rod.
Further, the vertical rod that described rocking arm is provided with installing hole by a cross bar be fixedly connected with push rod lower end and upper end, lower end is provided with derivation breach forms, and described cross bar is fixedly connected with the upper end of vertical rod, and one-body molded.When push rod moves up and down; the cross bar in rocking arm moves up and down thereupon; because its vertical rod upper end is enclosed within the rocker shaft of frame lower end; therefore when rocking arm moves up; cross bar moves up thereupon, thus drives the vertical rod be fixedly connected with cross bar to move right, and when rocker arm moving downward; cross bar moves down thereupon, thus the vertical rod promoting to be connected with cross bar is moved to the left.
Further, for the ease of installing rocking arm, in the lower end of frame, the upper end of movable blades is provided with an outwardly and rocker shaft that is that match with rocking arm installing hole.In the middle part of movable blades, be provided with a lever matched with the derivation breach of rocking arm, in use, after rocking arm swings, namely can promote the lever on movable blades, drive movable blades to swing together immediately.
Compared with prior art, the lower cutter device tool of grain header that the utility model obtains has the following advantages:
By the connection of fork controls power shaft and output shaft or be separated, and then control the motion or static of the cam mechanism, push rod and the rocking arm that drive movable blades to move, achieve the independent control of movable blades, movable blades can be avoided to move back and forth in the process of walking, and then increase the service life of movable blades.
