empty spoon of the seeding chain spoon 21 can be detected in advance in time, and
the empty spoon is detected to move to the bottom seeding stage. This period of time
is the delay time for the PLC to send the action command signal to the reseeding
servo motor 34. When the time is up, the reseeding servo motor 34 will act, and the
reseeding chain spoon 31 will move for a distance of one plant spacing, just to complete the reseeding.In the present invention, the installation height of the vibration motor 24 is lower than the infrared photoelectric sensor 71 of the missing sowing detection device 7 to ensure that the seed picking chain spoon 21 starts the missing sowing detection after seed picking is completed and smooth movement is achieved.
In the present invention, the PLC control system sends a control signal to the
reseeding servo motor 34 as an action command signal. When the seeding chain
spoon 21 has an empty spoon, the phenomenon of missied sowing occurs. When this
phenomenon occurs, the PLC calculates according to its own programming. The time
when the action is issued. This time point is obtained by the accumulation of three
times.The first time point is the time point of the seeding chain spoon 21 from the
current empty spoon time point, and the time point of the distance traveled by the
chain spoon movement to the final seeding stage is TI; the second time point is the
reseeding servo motor 34 action occurs and the reseeding chain spoon is driven to
move a distance of one plant distance at this time point T2; The third time point is that
after the seed potato falls off the reseeding chain spoon and falls into the seeding ditch,
the time point of this distance is T3.The accumulation of three time points is used as
the delay time for the PLC to send a command to the reseeding servo motor.Under the
accumulation of three time points of TI, T2 and T3, this accumulation time point is
programmed into the PLC control system. At the same time, after the PLC sends out
an action command, it is necessary to ensure that the reseeding device 3 moves a
distance of one plant spacing, so that it is convenient to calculate the time point T2. At
the same time, in the present invention, it is ensured that after the reseeding device 3
operates, the refilled seed potatoes will fall into the correct position after the seeds are
thrown out during normal seeding, so as to ensure the plant spacing for normal
planting and meet the planting requirements of users.
When the present invention works, after the planting machine is towed and
connected to the tractor, the planting machine is driven by the tractor to work, and the
tractor inputs power into the gearbox transmission system to drive the soil covering
device 8 to work, and ridges the seed potatoes after sowing. At the same time, during
the rotation of the left and right ground wheels 11, the seeding device 2, the
fertilization device 4, and the pesticide applicator 5 are driven by the chain
drive.When there is a missed sowing phenomenon, the reseeding device 3 sends out a
reseeding action to reseed in time; the soil covering device 8 covers the soil and
ridges in time, the film covering device 9 covers the ridge surface with a plastic film,
and the drip irrigation tape device 10 spreads the drip irrigation tape on the ridge. The
surface of the soil layer, therefore, multiple operations such as precision seeding,
fertilization, pesticide application, soil covering, film covering, and drip irrigation belt
laying can be completed at one time through the present invention.
