Description

Planter alignment device

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of planter alignment device of suitable hillside fields operation.

Background technology

When seeder carries out seeding operation in hillside fields, seeder can run-off the straight, by being rigidly connected, be singly hinged or four The planter of bar connection also can the run-off the straight with the inclination of seeder connection frame, this can be caused on the planter The transaction capabilities of feed mechanism for seed decline, and the phenomenon of broadcast leakage or replay occur, influence seeding operation quality, such as beautiful for imtertilled crop , frequently with bucket wheel type seeding unit, when bucket wheel upper end is outward-dipping, often there is broadcast leakage phenomenon, when bucket wheel upper end is tilted inwards in rice When, often there is resowing phenomenon, so that there is one-hill-multiple-plant or the disconnected ridge that is short of seedling, therefore, develop a kind of and supporting seeder be adapted to The planter alignment device of hillside fields operation, makes it in seeding operation, is always ensured that the vertical state of planter, to ensure The transaction capabilities of feed mechanism for seed, have very important significance.

The content of the invention

The problem of purpose of the invention exists aiming at above-mentioned prior art, designs a kind of planter levelling dress Put, by being linked between beam link and four bar side arms using being rotatably assorted, and balance weight iron is fixedly mounted with using four bar side arm lower ends Action of Gravity Field, is realized when seeder mainframe deflection, the state seeding operation that planter still can be vertical, it is ensured that feed mechanism for seed Seeding quality.

What the purpose of the invention was realized in：Cantilevered axle, the beam connection are fixedly mounted with beam link central right Frame both sides set angle limiting plate, and -25 °~25 ° of beam link angle range assembles taper roller in cantilevered axle by round nut Bearing inner race, the taper roll bearing outer ring is packed on bearing block by positioning sleeve, and the bearing block is packed in by bolt On four bar side arms, the four bars side arm lower end is fixedly mounted with balance weight iron, before and after upper and lower connecting rod by bearing pin respectively with four bar side arms and four Bar after-frame is hinged, and middle and lower part is fixedly mounted with lower limiting board on the left of the four bars side arm.

The invention is by application taper roll bearing by the bearing block rolling assembling being packed on four bar side arms in beam In the cantilevered axle that link center is fixedly mounted with, and balance weight iron is fixedly mounted with the lower end of four bar side arms, when beam link is with seeder machine During frame deflection, by the Action of Gravity Field of balance weight iron, levelling torque is applied to four bar side arms of the rolling assembling in cantilevered axle, makes to lead to Vertical job state is presented in the planter being fixedly mounted with the four bar after-frames for crossing upper and lower connecting rod link, it is ensured that the operation of feed mechanism for seed Quality, meanwhile, the device has that structure is novel, simple, reasonable, easy to operate, operation quality is reliable, spy applied widely Point.

Embodiment

The embodiment to the invention is described in detail below in conjunction with the accompanying drawings：

A kind of planter alignment device, cantilevered axle 4, the both sides of beam link 3 are fixedly mounted with the central right of beam link 3 Angle limiting plate 15 is set, and -25 °~25 ° of 3 angle range of beam link assembles taper roller in cantilevered axle 4 by round nut 7 The inner ring of bearing 5, the outer ring of taper roll bearing 5 is packed on bearing block 6 by positioning sleeve 8, and the bearing block 6 is by bolt 9 It is packed on four bar side arms 2, the lower end of four bars side arm 2 passes through bearing pin 10 before and after being fixedly mounted with balance weight iron 1, upper and lower connecting rod 11,12 It is hinged respectively with four bar side arms 2 and four bar after-frames 14, lower limiting board 13 is fixedly mounted with the left side middle and lower part of four bars side arm 14.

Seeder carries out seeding operation in sloping upland, when seeder is glanced off with topography variation, is packed in seeder Beam link 3 on roof beam structure is glanced off therewith, and the central right of beam link 3 is fixedly mounted with cantilevered axle 4, and circle is passed through in cantilevered axle 4 Nut 7 assembles the inner ring of taper roll bearing 5, and the outer ring of taper roll bearing 5 is packed on bearing block 6 by positioning sleeve 8, bearing block 6 are packed on four bar side arms 2 by bolt 9, and the lower end of four bar side arm 2 is fixedly mounted with balance weight iron 1, so far, four bar side arms 2 and beam link 3 Between be rotating link, when beam link 3 glances off initial stage, the same deflection of four bar side arm 2, at this moment, due to breeding iron 1 Action of Gravity Field, four bar side arms 2 are applied at the axle center of cantilevered axle 4 with levelling torque, four bar side arms 2 start to rotate, until levelling Torque disappears, i.e. four bar side arms 2 are in vertical state, and at this moment, the four bar after-frames 14 linked with it by upper and lower connecting rod 11,12 are same Sample is in vertical state, and the planter on four bar after-frames 14 keeps vertical state operation, it is ensured that the operation matter of feed mechanism for seed Amount, the angle limiting plate of the both sides of beam link 3 limits the drift angle of planter in the range of -25 °~25 °.
