Description
Technical field
The present invention relates to seeder compensation device fields more particularly to a kind of replay broadcast leakage for seeder to compensate dress
It sets.
Background technique
Seeder is usually at the uniform velocity walked on field when carrying out seeding operation, and makes seed with the identical time
Interval falls to field one by one, and seed can be made to be spaced successively uniformly sowing at the same distance on field.But actually make
In, of both seed and seeder due to, the problem of being easy to produce replay and broadcast leakage.Replay be due to two even
Stick to each other between multiple seeds makes multiple seeds be collected as the same particulate matter and falls to field from seeder, just makes
It is replayed on the same position in field；And broadcast leakage is often as seeder itself and causes the time fallen between two seeds
Be spaced it is too long, make next seed fall before seeder advance distance it is excessive, two seeds fall the distance interval of position just
It will increase, make the position that will appear a broadcast leakage between two seeds.Existing seeder shortcoming can be avoided replay and broadcast leakage
Ability, broadcast leakage and replay situation are easy to appear under field seeding complex job environment and to influence crop yield and agricultural raw
Produce cost.
Summary of the invention
To solve the problems, such as that existing seeder is easy to appear replay and broadcast leakage, the present invention provides one kind to be used for seeder
Replay broadcast leakage compensation device.
Used technical solution is the present invention to solve above-mentioned technical problem: a kind of replay broadcast leakage benefit for seeder

According to the above technical scheme, the beneficial effects of the present invention are:
Provided by the present invention for the replay broadcast leakage compensation device of seeder, be mounted on the discharge port of seeder, make seed from
It all can first drop down onto the inner cavity of shell, and can be collided after being fallen in seeder with point kind of a plate, and point kind of plate is in motor
Under control, state diagonally downward is remained, seed will be with the surface collision of point kind of plate side upward, and direction after an impact
The side rebound opposite with seeder direction of travel, then field is fallen to from shell.In the present invention when replaying, mutually
It can be separated after the seed of adhesion and point kind of plate collision reaction, thus just can be from housing cavity after separating the seed of stick to each other
The case where small end opening is fallen, and the seed of stick to each other can be made to respectively fall on the different location in field, effectively avoids replay.
In the present invention be provided with opposite type sensor and controller, seed between two opposite type sensors by when will be monitored
Arrive, opposite type sensor will to controller issue signal, when there is broadcast leakage, also mean that before next seed is fallen when
Between be spaced excessive, the time interval that controller receives next signal also just will increase and beyond preset time interval, at this time
Controller controls electric motor starting, rotates kind of a plate to the side of the close big end opening of housing cavity, thus increase point kind of plate and
Angle between vertical direction when seed continues to fall on point kind of plate, falls position from small end opening after collision reaction
Also will towards prolonging behind the side opposite with seeder direction of travel, make seed from big end opening fall position and seed collides
Increase from falling between position for small end opening along the distance of the horizontal direction of travel of seeder after rebound, to make next seed
Fall after position also occurs and prolong, it will be able to fall next seed in broadcast leakage position to realize that broadcast leakage compensates, the present invention is just
Can replay to seeder and broadcast leakage phenomenon all carry out effective compensation, avoid due to replay and broadcast leakage and influence crop yield and
Agriculture production cost promotes the sowing efficiency and quality of seeder.
