The present invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figures 1 to 3, the invention provides a kind of conveyer belt seeding evenness device, it includes plants case 1, protecting cover 2, conveying
Portion, clear kind portion and portion of charging seed, the outlet at bottom top of plants case 1 are provided with dividing plate, seed inlet 12, protecting cover are offered in dividing plate side wall
2 are connected with the bottom of plants case 1, and delivery section, clear kind portion and the portion of charging seed are arranged in protecting cover 2；Wherein, it is defeated to include rubber for delivery section
Band 3, conveyer belt main driving wheel 4, conveyer belt is sent to include seeds depositing wheel 11, the main biography of conveyer belt from drive 5 and tensioning wheel 6, the portion of charging seed
Driving wheel 4 and conveyer belt are separately positioned at the outlet at bottom upper-lower position of plants case 1 from drive 5, and conveyer belt main driving wheel 4 with
Conveyer belt is acclivitous straight line transportation section from rubber conveyer belt 3 between drive 5, and plants case 1 is defeated with this by seed inlet 12
Send section to connect, seeds depositing wheel 11 is arranged at the outlet at bottom of protecting cover 2, rubber conveyer belt 3 across conveyer belt main driving wheel 4, conveying
Band forms the conveying stroke of seed from drive 5 and seeds depositing wheel 11, in rubber of the conveyer belt between drive 5 and seeds depositing wheel 11
The tensioning wheel 6 of its rate of tension can be adjusted by being set on conveyer belt 3；It is uniformly distributed on the periphery in the outside of rubber conveyer belt 3 some
What is be inclined to set broadcasts tooth 31, and adjacent two broadcast the type hole of formation storage seed between tooth 31；Clear kind portion include rubber seed clearing wheel 7,
Clear kind drive sprocket 8, clear kind driven sprocket 9 and seed clearing wheel chain 10；Conveyer belt main driving wheel 4, clear kind drive sprocket 8 with row
Kind device sprocket wheel 13 is coaxially connected, and clear drive sprocket 8 of planting is connected by seed clearing wheel chain 10 with clear kind driven sprocket 9, is planted clearly driven
Sprocket wheel 9 and rubber seed clearing wheel 7 are coaxially connected, and rubber seed clearing wheel 7 and the rubber conveyer belt above the outlet at bottom of plants case 1
3 tangent settings, feed mechanism for seed sprocket wheel 13 by seeder power drive and as the power source of whole evenness device.
Further, pyramidal pits are provided with the type hole on the outer circumference face of rubber conveyer belt 3, ensure that seed is filled with type hole
And stable transport is charged seed to the outlet at bottom of protecting cover 2, has spaced tooth-shape structure in the inner peripheral surface of rubber conveyer belt 3,
Conveyer belt main driving wheel 4, conveyer belt driven pulley 5, tensioning wheel 6 and seeds depositing wheel 11 are toothed wheel, are engaged with rubber conveyer belt 3
Connection.
Further, protecting cover 2 includes preceding protecting cover 21 and rear protecting cover 22, and preceding protecting cover 21 is fixedly connected with the bottom of plants case 1, after
Protecting cover 22 is detachable connection with preceding protecting cover 21 and plants case 1, so, when being gone wrong inside evenness device, after pulling down

Further, rubber conveyer belt 3 is endless belt, and rubber conveyer belt 3 is by conveyer belt main driving wheel 4, conveyer belt from biography
Driving wheel 5 and seeds depositing wheel 11 support and drive to form the seed of circulation conveying stroke, are disposably completed during circulation rotating
Fill kind, clear kind, shield are planted, conveyed, charging seed, and the height that outlet at bottom of the rubber conveyer belt 3 through protecting cover 2 is charged seed is only 4 centimetres.
The course of work of the present invention is as follows：During tractor seeder operation, by the rotation of seeder ground wheel, by power via
Each portion's drive sprocket is delivered on feed mechanism for seed sprocket wheel 13, and feed mechanism for seed sprocket wheel 13 rotates, and driving conveying belt main driving wheel 4 and clear kind are led
Movable sprocket 8 rotates, and conveyer belt main driving wheel 4 rotates counterclockwise (as shown in Figure 1), and driving conveying belt is from drive 5 and seeds depositing wheel
11 rotate, and so as to drive rubber conveyer belt 3 to walk counterclockwise, the seed in plants case 1 enters rubber conveyer belt 3 through seed inlet 12
Acclivitous straight line transportation section, the seed of the transportation section broadcast the work of tooth 31 in the effect and being tilted in rubber conveyer belt 3 of gravity
Quickly it is charged into lower in type hole, when rubber conveyer belt 3 moves with the unnecessary seed of the seed and type hole outer that are filled with type hole
When moving in the pivot region of rubber seed clearing wheel 7, because clear kind drive sprocket 8 rotates counterclockwise, the clear kind inverse time of driven sprocket 9 is driven
Pin rotates, and clear kind driven sprocket 9 and rubber seed clearing wheel 7 are coaxially connected, and then the rotate counterclockwise of rubber seed clearing wheel 7 is (such as Fig. 1 institutes
Show), rubber seed clearing wheel 7 is with linear velocity of more than 4 times higher than 3 movement velocity of rubber conveyer belt by the unnecessary seed brush in type hole outer
The bottom of plants case 1 is gone back to, a remaining seed in the type hole after the cleaning of rubber seed clearing wheel 7, by the type hole on rubber conveyer belt 3
The bottom of seeds depositing wheel 11 is escorted always to discharge at the outlet at bottom of protecting cover 2, is charged seed in the place of distance 4 centimetres of ditch of kind, by
Charged seed highly in greatly reducing, and before charging seed, seed is in type hole, fundamentally ensure that seed not by outer
Portion's factor influences and maintains its uniformity, really solves other feed mechanism for seeds because the interference of charge seed excessive height or grain conductor is made
Into sowing evenness difference the problem of, improve the sowing uniformity, reach the purpose of crop yield.
The present invention is only illustrated with above-described embodiment, and structure, set location and its connection of each part are all to have
Changed.On the basis of technical solution of the present invention, all improvement carried out according to the principle of the invention to individual part or equivalent
Conversion, should not be excluded outside protection scope of the present invention.
