[0017] In order to solve the above problems, the technical solution adopted by the method of sowing using the above corn test seeder is as follows: the method comprises the following steps:

[0018] The first step is to load the seeds

[0019] According to the test requirements, each corn seed to be sown is placed in the corresponding seed storage room and covered with a seed box cover;

[0020] The second step is to place the seed box with seeds on the seed box track of the seed box platform.

[0021] With the seed box cover facing downward, place the seed box on the seed box track so that the lower opening of the independent seed storage room in the front row of the seed box is located on the side of the seed drop hole;

[0022] The third step is to sort

[0023] The seed box is pushed toward the seed drop hole, the seed box cover is blocked, and the seed box frame with an independent seed storage room moves forward, so that the independent seed storage room on the seed box frame is aligned with the seed drop hole, and the seeds in the independent seed storage room enter the top of the seed partition plate at the bottom of the seed guide tube;

[0024] Step 4: Planting

[0025] The first solenoid valve drives the seed separator to move backward, and the seeds fall into the seed separation box;

[0026] Step 5: While sowing, proceed to the next step of seed division

[0027] The corn test planter moves forward, the traveling wheel rotates, driving the rotating wheel to rotate. When the through hole on the rotating wheel passes through the photosensitive switch, the photosensitive switch transmits a signal to the control mechanism. The control mechanism controls the second solenoid valve to open, driving the push rod to push up, and the seeds in the groove at the top of the push rod move up with the push rod. When the seeds reach the seed outlet, the seeds enter the ground through the seed outlet and the seed tube. At the same time, the push rod moves downward, and the top of the push rod retracts to the bottom of the seed box. The seeds in the seed box enter the groove at the top of the push rod; the corn test planter continues to move forward to sow until the designed length is reached;

[0028] After the seeds in the seed guide tube fall into the seed separation box, the first solenoid valve pushes the seed partition plate to block the bottom of the seed guide tube, and the seed box is pushed forward by the seed box pushing mechanism, so that the independent seed storage room on the seed box frame is aligned with the seed drop hole, and the seeds in the independent seed storage room enter the top of the seed partition plate at the bottom of the seed guide tube;

[0029] Step 6: Remove remaining seeds

[0030] Remove the remaining seeds from the seed box;

[0031] Step 7, repeating from step 4 until all the seeds in the seed box have fallen, and removing the old seed box;

[0032] Step 8. Replace the seed box with a new one containing seeds, and then repeat from step 2 until the sowing is completed.

[0033] For a corn test planter in which the upper part of the rear box body is movably connected to the baffle plate through a connecting pin, the planting method includes the following steps:

[0034] The first step is to load the seeds

[0035] According to the test requirements, each corn seed to be sown is placed in the corresponding seed storage room and covered with a seed box cover;

[0036] The second step is to place the seed box with seeds on the seed box track of the seed box platform.

[0037] With the seed box cover facing downward, place the seed box on the seed box track so that the lower opening of the independent seed storage room in the front row of the seed box is located on the side of the seed drop hole;

[0038] The third step is to sort

[0039] The seed box is pushed toward the seed drop hole, the seed box cover is blocked, and the seed box frame with an independent seed storage room moves forward, so that the independent seed storage room on the seed box frame is aligned with the seed drop hole, and the seeds in the independent seed storage room enter the top of the seed partition plate at the bottom of the seed guide tube;

[0040] Step 4: Planting

[0041] The first solenoid valve drives the seed separator to move backward, and the seeds fall into the seed separation box;

[0042] Step 5: While sowing, proceed to the next step of seed division

[0043] The corn test planter moves forward, the traveling wheel rotates, driving the rotating wheel to rotate. When the through hole on the rotating wheel passes through the photosensitive switch, the photosensitive switch transmits a signal to the control mechanism. The control mechanism controls the second solenoid valve to open, driving the push rod to push up, and the seeds in the groove at the top of the push rod move up with the push rod. When the seeds reach the seed outlet, the seeds enter the ground through the seed outlet and the seed tube. At the same time, the push rod moves downward, and the top of the push rod retracts to the bottom of the seed box. The seeds in the seed box enter the groove at the top of the push rod; the corn test planter continues to move forward to sow until the designed length is reached;

[0044] After the seeds in the seed guide tube fall into the seed separation box, the first solenoid valve pushes the seed partition plate to block the bottom of the seed guide tube, and the seed box is pushed forward by the seed box pushing mechanism, so that the independent seed storage room on the seed box frame is aligned with the seed drop hole, and the seeds in the independent seed storage room enter the top of the seed partition plate at the bottom of the seed guide tube;

[0045] Step 6: Remove remaining seeds

[0046] The control mechanism controls the third solenoid valve to open, and the swing rod swings to drive the lower end of the outer end to swing backward, so that the remaining seeds in the seed box fall from the seed box into the collecting trough, and then the control mechanism controls the third solenoid valve to close, and the lower end of the rear box body pushes forward under the action of the top spring to enclose the seed box with the baffle; the conveyor belt motor is turned on, and the discarded seeds that fall into the collecting trough move to the side of the waste seed outlet under the action of the scraper and fall from the waste seed outlet;

[0047] Step 7, repeating from step 4 until all the seeds in the seed box have fallen, and removing the old seed box;

[0048] Step 8. Replace the seed box with a new one containing seeds, and then repeat from step 2 until the sowing is completed.

According to the test needs, each corn seed to be sown is placed in the corresponding seed storage room and covered with a seed box cover; the seed box cover is downward, and the seed box is placed on the seed box track so that the lower mouth of the independent seed storage room in the front row of the seed box is located on the side of the seed drop hole; the seed box is pushed toward the side of the seed drop hole, the seed box cover is blocked, and the seed box frame with the independent seed storage room moves forward, so that the independent seed storage room on the seed box frame is aligned with the seed drop hole, and the seeds in the independent seed storage room enter the bottom of the seed guide tube and above the seed partition plate; The first solenoid valve drives the seed partition plate to move backward, and the seeds fall into the seed box; the corn test seeder moves forward, the traveling wheel rotates, driving the rotating wheel to rotate, and when the through hole on the rotating wheel passes the photosensitive switch, the photosensitive switch transmits a signal to the control mechanism, and the control mechanism controls the second solenoid valve to open, driving the push rod to push up, and the seeds in the groove at the top of the push rod move up with the push rod. When the seeds reach the seed outlet, the seeds enter the ground through the seed outlet and the seed tube, and at the same time the push rod moves downward, and the top of the push rod retracts to the bottom of the seed box, and the seeds in the seed box enter the groove at the top of the push rod; the corn test seeder continues to move forward to sow until the designed length is reached;After the seeds in the seed guide tube fall into the seed separation box, the first solenoid valve pushes the seed partition plate to block the bottom of the seed guide tube, and the seed box is pushed forward by the seed box pushing mechanism, so that the independent seed storage room on the seed box frame is aligned with the seed drop hole, and the seeds in the independent seed storage room enter the top of the seed partition plate at the bottom of the seed guide tube; the remaining seeds in the seed separation box are cleared; the above steps are repeated until all the seeds in the seed box have fallen, and the old seed box is removed; a new seed box with seeds is replaced until sowing is completed. The rotating wheel of the seed drop control device controls the speed through the traveling wheel, and the sowing is more uniform and the sowing depth is more uniform. The seeds are first blocked by the seed partition plate at the bottom of the seed guide tube. After the excess seeds in the seed separation box are taken out of the seed separation box, the first solenoid valve controls the seed partition plate to move away, and the seeds The seeds are quickly and simultaneously dropped into the seed box, thus avoiding uneven sowing caused by different distances from the seed box to the seed box; the second solenoid valve controls the push rod to push the seeds out of the seed box and drop them into the foot of the building, sowing is even; after the push rod retracts, the seeds in the seed box are gathered to the top of the push rod under the vibration of the seed box, which is more convenient to use; secondly, since the upper end of the baffle plate is inclined forward, when the seeds are pushed on the push rod, the seeds are attached to the rear side of the baffle plate due to gravity, while the seeds next to the push rod remain still in the seed box under the action of gravity, and when reaching the seed outlet, the seeds enter the ground through the seed outlet and the seed tube due to gravity. When the baffle plate is in a vertical direction, it is easy to cause the seeds to fall off when the seeds are pushed on the push rod, resulting in uneven sowing and When the seeds reach the seed outlet, it is not easy for them to fall into the ground through the seed outlet, which makes it more convenient to use. The upper end of the baffle is tilted forward at an angle of 8 to 30 degrees. When the inclination angle of the baffle is too small, the seeds are easily caused to fall off from the top of the push rod, and cannot be discharged from the seed outlet when reaching the seed outlet. When the inclination angle of the baffle is too large, the seeds located around the push rod are also easily brought to the seed outlet during the pushing process of the push rod, resulting in uneven sowing. Thirdly, since the rear box body is semi-cylindrical and the bottom plate is hemispherical, the seeds are more likely to fall into the groove at the top of the push rod when the top of the push rod is withdrawn to the bottom of the seed box, which avoids the situation that the seeds cannot fall on the top of the push rod when the top of the push rod is withdrawn to the bottom of the seed box. Fourthly, since the upper part of the rear box body is connected to the A connecting pin is arranged between the baffles, a baffle is arranged on the frame at the rear of the rear box body, a top spring is arranged between the baffle and the rear box body, a swing rod is arranged on the frame body behind the baffle, a pull rope connected to the rear box body is arranged on the swing rod, a third solenoid valve is arranged on the frame body, the third solenoid valve is control-connected with the control mechanism, the third solenoid valve is connected with the swing rod, after sowing of one variety is completed, the control mechanism controls the third solenoid valve to open, drives the swing rod to rotate, the pull rope pulls the rear box body to swing backward around the connecting pin shaft at the upper end of the rear box body, the seeds in the seed box fall along the rear side of the baffle, and then the rear box body is pushed forward under the action of the top spring, the rear box body and the baffle enclose a seed box, which is more convenient to use;Fifth, since a seed guide plate is provided at the lower end of the baffle, a collecting trough is provided at the lower end of the seed guide plate, a waste seed outlet is provided at the bottom of one end of the collecting trough, a scraper is provided in the collecting trough, and both sides of the scraper are respectively connected to the two ends of the conveyor belt, and the conveyor belt is connected to the conveyor belt motor power, the control mechanism controls the third solenoid valve to open, and the swing of the swing rod drives the lower end of the outer end to swing backward, so that the remaining seeds in the seed box fall from the seed box into the collecting trough, and then the control mechanism controls the third solenoid valve to close, and the lower end of the rear box body is pushed forward by the top spring to enclose the seed box with the baffle; the conveyor belt motor is turned on, and the discarded seeds that fall into the collecting trough move to the side of the waste seed outlet under the action of the scraper and fall from the waste seed outlet, which is more convenient to use. Convenient; Sixth, since a camera and a counting probe are arranged above the seed outlet, a display, an operating platform and a broadcasting speaker are arranged on the seed box platform, the camera is connected to the display, and the counting probe is connected to the broadcasting speaker, the sowing situation of each seed outlet can be displayed on the display, and the counting probe can also broadcast the sowing situation and the number of seeds through the broadcasting speaker, which is more convenient to use; Seventh, since an oblique seed-blocking plate is arranged on the baffle plate above the seed outlet, it is avoided that the seeds pass over the seed outlet due to inertia during the pushing process of the push rod, which is more convenient to use; Eighth, since a seed-discharging notch is arranged in front of the groove, the seeds can pass through the seed outlet smoothly through the seed-discharging notch when they reach the seed outlet position. ; BRIEF DESCRIPTION OF THE DRAWINGS

The lifting mechanism 84 is a second solenoid valve, and the second solenoid valve is control-connected to the control mechanism 23.

[0064] According to the needs of the experiment, each corn seed to be sown is placed in the corresponding seed storage room 52 and covered with the seed box cover 51; the seed box cover 51 is facing downward, and the seed box 5 is placed on the seed box track 11, so that the lower mouth of the independent seed storage room in the front row of the seed box is located on the side of the seed hole 10; the seed box 5 is pushed toward the side of the seed hole 10, the seed box cover 51 is blocked, and the seed box frame 53 with the independent seed storage room 52 moves forward, so that the independent seed storage room 52 on the seed box frame 53 is aligned with the seed hole 10, and the seeds located in the independent seed storage room 52 enter the bottom of the seed guide tube and above the seed partition plate. The first solenoid valve 15 drives the seed partition plate 16 to move backward, and the seeds fall into the seed box 4; the corn experimental seeder moves forward, the traveling wheel 1 rotates, driving the rotating wheel 19 to rotate, and when the through hole 21 on the rotating wheel 19 passes the photosensitive switch 22, the photosensitive switch 22 transmits a signal to the control mechanism 23, and the control mechanism 23 controls the second solenoid valve to open, driving the push rod 82 to push up, and the seeds in the groove 83 at the top of the push rod 82 move up with the push rod 82. When the seeds reach the seed outlet 64, the seeds enter the underground through the seed outlet 64 and the seed tube 13, and at the same time, the push rod 82 moves downward, and the top of the push rod 82 retracts to the bottom of the seed box, and the seeds in the seed box 4 enter the groove 83 at the top of the push rod 82; the corn experimental seeder continues to move forward to sow until the designed length is reached. After the seeds in the seed guide tube 7 fall into the seed box 4, the first solenoid valve 15 pushes the seed partition plate 16 to block the bottom of the seed guide tube 7, and the seed box 5 is pushed forward by the seed box pushing mechanism 12, so that the independent seed storage room 52 on the seed box frame 53 is aligned with the seed drop hole 10, and the seeds located in the independent seed storage room 52 enter the top of the seed partition plate 16 at the bottom of the seed guide tube 7. Remove the remaining seeds in the seed box 4; repeat the above steps until all the seeds in the seed box have fallen, and remove the old seed box; replace the new seed box with seeds until sowing is completed. The wheel 19 of the seed drop control device 9 controls the rotation speed through the traveling wheel 1, sowing is more uniform, and the sowing depth is more uniform. The seeds are first blocked by the seed partition plate 16 at the bottom of the seed guide tube. After the excess seeds in the seed box 4 are taken out of the seed box, the first solenoid valve 15 controls the seed partition plate 16 to move away, and the seeds fall into the seed box 4 quickly and simultaneously, avoiding uneven sowing caused by different distances from the seed box to the seed box; the second solenoid valve controls the push rod 82 to push the seeds out of the seed box and drop them into the foot of the building, sowing is uniform, and after the push rod retracts, under the vibration of the seed box, the seeds in the seed box are gathered at the top of the push rod, which is more convenient to use.

[0065] The upper end of the baffle 61 is inclined forward. When the seeds are pushed on the push rod 82, the seeds are attached to the rear side of the baffle 61 due to gravity, and the seeds next to the push rod are stationary in the seed box 4 under the action of gravity. When the seeds reach the seed outlet 64, the seeds enter the ground through the seed outlet 64 and the lower seed tube 13 due to gravity. When the baffle is in a vertical direction, it is easy to cause the seeds to fall off when the seeds are pushed on the push rod, resulting in uneven sowing. Moreover, when the seeds reach the seed outlet, it is not easy for the seeds to fall into the ground through the seed outlet, which is more convenient to use. The upper end of the baffle 61 is inclined forward at an angle of 8 degrees to 30 degrees. When the baffle is tilted too small, it is easy to cause the seeds to fall off from the top of the push rod, and cannot be discharged from the seed outlet when reaching the seed outlet 64. When the baffle is tilted too large, the seeds located around the push rod are also easily brought to the seed outlet during the push process of the push rod, resulting in uneven sowing.

[0066] The rear box body 62 is semi-cylindrical and the bottom plate 63 is hemispherical; in this way, when the top of the push rod is withdrawn to the bottom of the seed box, the seeds are more likely to fall into the groove 83 at the top of the push rod 82, avoiding the situation that the seeds cannot fall on the top of the push rod when the top of the push rod is withdrawn to the bottom of the seed box.
