Fig. 1 is the structural representation of the seed removal of impurities screening plant in maize harvesting machine embodiment of the present invention, is also the structural representation of a kind of embodiment of seed removal of impurities screening plant in the present invention simultaneously;
Fig. 2 is the end view of Fig. 1.
Embodiment
The embodiment of maize harvesting machine is as shown in Figure 1 and 2: comprise the corn harvesting apparatus of mainframe and upper setting thereof, debarker and seed removal of impurities screening plant, seed removal of impurities screening plant comprises the sieve nest 6 that screening plant frame and length direction extend along front and back, sieve nest 6 by motion and follower can produce movable amplitude and move up and down amplitude be assemblied in screening plant frame, motion and follower are arranged at intervals at the rear and front end of sieve nest along the longitudinal direction, and motion and follower are divided into the both sides up and down of sieve nest.Motion is included in and frame arranges, pivot center extends and the driving shaft 1 driven by corresponding power source in left-right direction, driving shaft 1 is installed with the length actuating arm consistent with the radial bearing of trend of driving shaft 12, motion also comprises the eccentric block 5 with the articulated position that two axis extend all in left-right direction, two articulated position eccentric settings of eccentric block, an articulated position of eccentric block 5 is hinged and connected by link 4 and sieve nest 6, another articulated position place is hinged with connecting rod 3, connecting rod 3 is an expansion link with straight-line displacement telescopic adjustment amount, connecting rod 3 is hinged and connected away from one end of eccentric block 5 and actuating arm 2 one end away from driving shaft 1, sieve nest 6 is driven to tilt forward and the reciprocating motion of tilting backwards to make eccentric block 5 when driving shaft circumference is rotated, wherein eccentric block, connecting rod and actuating arm constitute planar linkage transmission mechanism.Follower comprises rocking lever 7; lower end of rocking lever 7 is hinged and connected with frame by the first articulated structure 8; upper end is hinged and connected with sieve nest 6 by the second articulated structure 9; during to drive sieve nest 6 to move at motion; rocking lever also moves thereupon; axially extending all in left-right direction of first and second articulated structure; rocking lever 7 has two and the left and right sides being arranged at sieve nest corresponding respectively; two rocking levers 7 are the U-shaped structure with vertical arm 7-2 and two transverse arm 7-1, and wherein two transverse arms of first and second articulated structure and respective rocker arm bar 7 are hinged and connected.
During work, can be dropped on the compass screen surface of sieve nest 6 by the corn kernel that debarker falls, bract and broken stipe, driving shaft 1 circles under the driving of corresponding power source, corresponding actuating arm 2 also moves around the pivot center of driving shaft 1,3, connecting rod stretches under the drive of actuating arm 2 while swing in certain angle, the swing of connecting rod can make eccentric block swing thereupon, and then makes the mobile range on sieve nest generation fore-and-aft direction; In the process that actuating arm upwards rotates, connecting rod first can reach oneself a flexible stroke limit position, actuating arm continues upwards to rotate subsequently, connecting rod pulls on eccentric block and sieve nest and moves, thus make sieve nest produce mobile range on an above-below direction, under the synthesis of both direction motion amplitude, sieve nest will tilt forward and the reciprocating motion of tilting backwards along with the rotation of actuating arm.Sieve nest is reciprocating while, and follower is also and then servo-actuated.Motion and follower synergy; whole sieve nest is made to produce the Oscillation Amplitude of front and back and above-below direction; make mutually to be rolled, jump, collide and be separated with broken stipe on the compass screen surface of sieve nest by the corn kernel that debarker falls, Bao Ye; suitable amplitude and vibration frequency make corn kernel thoroughly be separated with bract, broken stipe; maize kernel falls into corresponding kernel recovery box through sieve nest, and bract and broken stipe are then discharged by body.Greatly reduce the percent of loss of seed, achieve high yield good harvest; The use of expansion link, reduces sieve nest Oscillation Amplitude in all directions, prevents corn kernel, bract and broken stipe from being deviate from by the top of sieve nest, also reduces whole complete machine size in the vertical direction simultaneously.
In other embodiment of this maize harvesting machine: the rocking lever lifting that can be arranged between frame and sieve nest draws other followers such as the rope of effect or chain to replace; When needing sieve nest to have less amplitude, the reduction that the distance between follower and motion can be suitable, is such as arranged on the middle part of sieve nest, front portion or rear portion simultaneously by follower and motion; Link also can not be established, and now eccentric block can directly be articulated with on sieve nest; Follower and motion can also be arranged at upside or the downside of sieve nest simultaneously; Certainly, connecting rod can also be a common rigid rod without Telescopic.
The embodiment of seed removal of impurities screening plant is as shown in Figure 1 and 2: the seed removal of impurities screening plant of concrete structure as described in above-mentioned each maize harvesting machine embodiment of seed removal of impurities screening plant, is not described in detail in this.
