[0002] Corn is an annual monoecious cross-pollinating plant with tall plants and strong stems. It is an important food crop and feed crop, and also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. The existing devices still have some defects; for example;

[0003] For example, an integrated corn planting machine with announcement number CN111406458A, when in use, includes a receiving plate, a bearing frame, a bottom beam, a driving wheel, a rotary tiller wheel, a storage bin, a water tank, a main linkage shaft, a telescopic tube, a first crankshaft, a second crankshaft, a third crankshaft, a sleeve, a vertebral plate, a first set, a passive gear, a piston, a groove, a piston pump, and a second set; a bearing frame is integrated on one side of the receiving plate, and a bottom beam and passive gears are integrated from one side to the other side of the bearing frame. By setting the rotation radius of the first crankshaft to be greater than that of the second crankshaft, and the length of the telescopic tube to be greater than that of the sleeve, a quadrangular pyramid is formed between the vertebral plates, and a torsion spring is nested on the hinge at the connection between the vertebral plate and the sleeve. When the sleeve is pushed down by the second crankshaft, the vertebral plate at the bottom of the sleeve can be inserted into the soil. Since the rotation radius of the first crankshaft is greater than that of the second crankshaft, the downward distance of the telescopic tube increases, and then the telescopic tube pushes the vertebral plate open to put down the corn seeds;

[0004] The above device has some problems. The device is cumbersome to use, and it is inconvenient to feed corn seeds during use. In addition, the sowing spacing adjustment effect is not good during use, and the spacing cannot be adjusted according to different needs.

[0026] When in use, after the front end of the connecting rod 18 is connected to the external moving mechanism through bolts, the box door on the top of the body 1 is opened through the hinge shaft and the corn seeds are added inside, the body 1 can be pulled to move through the wheels at the bottom. At the same time, during the movement, the first motor 2 inside the body 1 can be started to drive the first gear 3 to rotate. Since the first gear 3 and the second gear 4 are meshed, the second gear 4 drives the rotating rod 5 to rotate, so that the rotating rod 5 drives the third gear 6 below to rotate. At the same time, the third gear 6 and the fourth gear 7 are meshed, so that the fourth gear 7 drives the rotating shaft 8 to rotate, so that the rotating shaft 8 drives the rotating plate 9 to rotate, and the scraper 11 on the surface of the rotating plate 9 rotates. At this time, the through hole 10 on the surface of the rotating plate 9 coincides with the feeding pipe 21 inside the body 1. At the same time, the scraper 11 scrapes the corn seeds inside, so that the corn seeds pass through the feeding pipe 19 and enter the storage box 20 below the knife. Through the rotation of the rotating plate 9, it can be ensured that the corn seeds dropped each time will not be too much to cause internal blockage;

[0028] When it is necessary to sow, the spacing of sowing can be determined according to the needs. When the sowing spacing is small, the feed pipe 21 is connected to the position below the first discharge hole 15 by bolts. When the sowing spacing is medium, the feed pipe 21 is connected to the position below the second discharge hole 16 by bolts. When the sowing spacing is large, the feed pipe 21 is connected to the position below the third discharge hole 17 by bolts. When sowing is required at this time, the internal second motor 13 is started to drive the turntable 14 to rotate. According to different spacings, the positions of the first discharge hole 15, the second discharge hole 16 and the third discharge hole 17 are made to coincide with the feed pipe 21 below for feeding. At the same time, the push rod 12 can be started to drive the storage box 20 to descend, so that the feed pipe 21 enters the planting pit set in advance in the ground, and the corn seeds are put in at the same time.

During the movement, the first motor 2 inside the body 1 can be started to drive the first gear 3 to rotate. Since the first gear 3 and the second gear 4 are meshed, the second gear 4 drives the rotating rod 5 to rotate, so that the rotating rod 5 drives the third gear 6 below to rotate. At the same time, the third gear 6 and the fourth gear 7 are meshed, so that the fourth gear 7 drives the rotating shaft 8 to rotate, so that the rotating shaft 8 drives the rotating plate 9 to rotate, and the scraper 11 on the surface of the rotating plate 9 rotates. At this time, the through hole 10 on the surface of the rotating plate 9 coincides with the discharge pipe 21 inside the body 1, and the scraper 11 scrapes the internal corn seeds, so that the corn seeds pass through The feeding pipe 19 then enters the storage box 20 under the knife. By rotating the rotating plate 9, the corn seeds that descend each time will not be too much and cause internal blockage. When sowing is needed, the sowing spacing can be set as needed. When the sowing spacing is small, the feeding pipe 21 is connected to the position below the first discharge hole 15 by bolts. When the sowing spacing is medium, the feeding pipe 21 is connected to the position below the second discharge hole 16 by bolts. When the sowing spacing is large, the feeding pipe 21 is connected to the position below the third discharge hole 17 by bolts.
