The seeding device 2 and the reseeding device 3 are equipped with a missing sowing detection device 7, which is used to detect the missed seeding phenomenon of the seeding device Z in time, and issue an action command to the reseeding device 3 in tire to complete the missed seeding detection function. The missing sowing detection device 7 includes an infrared photoelectric sensor 71 and an intelligent control box 72. The infrared photoelectric sensor 71 is installed on the seeding tube 23 of the seeding device 2 to detect whether there is seed potato on the seeding spoon; The intelligent control box 72 is installed on the right front side of the seeding box 25, the intelligent control box 72 includes a touch screen, a PLO, and a stepping driver. The human-computer interaction is realized through the touch screen, and various parameter adjusiment functions can be realized. The infrared photoelectric sensor 71 belongs to the diffuse reflection type, and it comes with an infrared light source and a light receiving device. The light emitted by the hight source is reflecied by the potsto seed potato and received by the photosensitive element, and then processed by the intelligent control box 72 fo obtain the required information. When there is seed potato on the seeding chain spoon 21, the PLC in the intelligent control box 72 does not respond, and the reseeding device 3 does not operate; when there is no seed potato on the seeding chain spoon 21, the light emitted by the light source is not reflected, and the intelligent control If the required information is not obtained in the box 72, the PLC will respond and send an action signal to the resceding serve motor 34 in time, and the resceding servo motor 34 will act to complete the reseeding process. The infrared photoelectric sensor 71 is installed in the seeding device Z after the seeding is completed and the seeding chain spoon 21 18 in the rising stage. At this tie, the 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 rescoding serve motor 34 will act, and the LU501812 resceding chain spoon 31 will move for a distance of one plant spacing, just to complete the resceding. 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 bas an empty spoon, the phenomenon of missied sowing occurs. When this phenomenon occurs, the PLC calculates according to Us 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 T1: the second time point is the reseeding serve motor 34 action occurs and the reseeding chain spoon is driven 10 move a distance of ons plant distance at this time point T2, The third time point 15 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 15 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, F2 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 fo ensure that the reseeding device 3 moves a distance of one plant spacing, so that it is convenient to calculate the time point TZ. At the same time, in the present invention, if is ensured that after the reseeding device 3 operates, the refilled seed potatoes will fall into the correct position after the seeds are thrown ont 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 & 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 trigation tape on the ridge. The surface of the soil laver, therefore, multiple operations such as precision seeding, fertilization, pesticide application, soil covering,

film covering, and drip irrigation bell laving can be completed at one time through the present . . LU501812 invention.
