[0017] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. An intermittent rotary potato planting mechanism includes a base 30 and a bearing seat plate 23 fixedly mounted on a frame 6. A base plate 3 with a seed-dropping hole is fixedly mounted on the upper end of the base 30. A seed-feeding funnel 4 is fixedly mounted below the seed-dropping hole on the base plate 3. A notched annular boss 46 is fixedly mounted on the upper surface of the base plate 3, with the notch located above the seed-dropping hole on the base plate 3. A circular frame 2 is rotatably mounted above the notched annular boss 46. Ten seed-feeding cylinders 1 are evenly distributed and fixedly mounted on the circular frame 2 along the circumference. A seed-feeding funnel 4 is mounted on the bottom end of each seed-feeding cylinder 1. A bottom plate 49 is rotatably mounted on a pin Ⅲ 47. A torsion spring 48 is fitted onto the pin Ⅲ 47. The two ends of the torsion spring 48 are in close contact with the seeding cylinder 1 and the bottom plate 49, respectively. The bottom plate 49 is in a closed or open contact with the bottom port of the seeding cylinder 1. The bottom plate 49 is in close supporting contact with the notched annular boss 46. A seeding drive shaft 40 is fixedly mounted at the center of the circular cylinder frame 2. A spherical grooved wheel 39 is fixedly mounted on the lower end of the seeding drive shaft 40. Ten drive grooves 42 and ten fixed grooves are evenly distributed and staggered along the circumferential direction on the spherical grooved wheel 39. The base 30 has a slot 43, on which a dial shaft 41 is rotatably mounted via bearing seat IV 37. A transmission sprocket I 31 and a dial 38 are fixedly mounted at both ends of the dial shaft 41. A cylindrical pin 44 and a central positioning pin 45 are fixedly mounted on the end face of the dial 38. The cylindrical pin 44 sequentially engages with ten drive slots 42 on the spherical grooved wheel 39, and the central positioning pin 45 sequentially engages with ten positioning slots 43 on the spherical grooved wheel 39. Bearing seats I 27, II 18, and III 20 are mounted on the bearing seat plate 23. 26. The power input shaft 16 and the lower shaft 21 are respectively inserted into bearing housing I 27, bearing housing II 18 and bearing housing III 20. Double row sprockets 28, upper crank flywheel 13 and cam 25 are respectively fixed on both sides of the upper shaft 26. Drive sprocket II 17 and power input sprocket 33 are respectively fixed on both sides of the power input shaft 16. Drive sprocket III 22 and lower crank flywheel 19 are fixed on the lower shaft 21. Drive chain I 15 is sequentially mounted on drive sprocket II 17, drive sprocket III 22 and double row sprocket 28. Drive chain II 29 is mounted on double row sprocket 28 and drive sprocket I 31.A rocker arm 14 is hinged and suspended on the upper crank flywheel 13 via a connecting rod 12. One end of the rocker arm 14 is hinged to the lower crank flywheel 19, which can rotate relative to each other. A device plate seat 7 is fixed to the other end of the rocker arm 14. On the lower part of the device plate seat 7, a seeder plate 19 and a seeder plate 20 are respectively suspended and hinged via parallel pins 18 and 211, which are symmetrical and can swing relative to each other. The seeder plate 19 and the seeder plate 210 are in a closed or open fit with each other. On the upper opposite ends of the seeder plate 19 and the seeder plate 210, there are involute teeth that are integrally arc-shaped and mesh with each other. The two ends of the tension spring 36 are respectively connected to the seeder plate. On the upper sides of seeder plate I9 and seeder plate II10, wire seat 50 and support plate 51 are respectively fixed to the corresponding upper parts of seeder plate I9 and seeder plate II10; a pull arm 24 is hinged to the upper part of the bearing seat plate 23 and can swing back and forth; a roller 32 is rotatably mounted on the lower part of the pull arm 24, and the roller 32 is in contact with the cam 25 fixed on the upper shaft 26; a hanging plate 34 is fixed on the bearing seat plate 23; a pull wire 35 is sequentially inserted through the hanging plate 34 and the support plate 51, and the two ends of the pull wire 35 are respectively connected to the bottom end of the pull arm 24 and the wire seat 50 on seeder plate I9; an inoculation funnel 5 is installed on the upper end of the seeder plate seat 7, below the seeding funnel 4.
[0018] During operation, the external rotational power is transmitted through the power input sprocket 33, power input shaft 16, transmission sprocket II 17, transmission chain I 15, transmission sprocket III 22, double-row sprocket 28, transmission chain II 29, and transmission sprocket I 31 to drive the lower shaft 1, upper shaft 26, and dial shaft 41 to rotate. The lower shaft 21 and upper shaft 26 simultaneously drive the lower crank flywheel 19 and upper crank flywheel 13, and cam 25 to rotate at the same speed and in the same direction. Under the control of the rocker arm 14 and connecting rod 12, the device plate seat 7, inoculation funnel 5, seeder plate I 9, and seeder plate II 10 rotate. At the same time, the rotating dial shaft 41 drives the dial 38 to rotate, which is connected to the cylindrical pin 44 and the center. The positioning pins 45 engage sequentially with the ten drive grooves 42 and ten positioning grooves 43 on the spherical grooved wheel 39. The seeding drive shaft 40 drives the circular cylinder frame 2 and the ten seeding cylinders 1 fixedly mounted on it to rotate together. When the dial 38 rotates 360 degrees in one revolution, the seeding drive shaft 40 rotates 36 degrees (one-tenth of a revolution) to perform the seeding operation of one seeding cylinder 1, allowing the ten seeding cylinders 1 to complete intermittent rotation and seeding. When a seeding cylinder 1 rotates to the position above the notch of the notch-shaped annular boss 46, the bottom plate 49 on the bottom end of the seeding cylinder 1 disengages from the supporting contact of the notch-shaped annular boss 46. Under the combined action of the torsion spring 48 and the gravity of the seed tuber... As the bottom plate 49 rotates, it opens the bottom port of the seeding cylinder 1. Under the action of gravity, the seed tubers fall through the seed dropping hole on the bottom plate 3, the seeding funnel 4, and the inoculation funnel 5, which has reached its highest point in a periodic motion, into the space between the closed seeder plate I9 and seeder plate II10. When the seeding cylinder 1, after being seeded, rotates past the notch of the notch-shaped annular boss 46, the bottom plate 49, supported by the notch-shaped annular boss 46, overcomes the torque of the torsion spring 48 and rotates in the opposite direction, closing the bottom port of the seeding cylinder 1. At the same time, when the seeder plate I9 and seeder plate II10 periodically move to their lowest position and are inserted into the seedbed soil, the cam 25, fixed on the upper shaft 26, comes to a stop. The contact point is engaged with roller 32, pushing pull arm 24 to rotate on bearing seat plate 23. Through pull wire 35 and wire seat 50, the seeder plate I9 rotates around pin shaft I8 on plate seat 7. With the engagement of the arc-shaped involute teeth on seeder plate I9 and seeder plate II10, seeder plate II10 also rotates around pin shaft II11 on plate seat 7. Seeder plate I9 and seeder plate II10 open, and potato tubers fall into the soil holes, completing the seeding. Afterwards, the cam 25, which continues to rotate, disengages from roller 32 at its far rest point. Under the tension of tension spring 36, seeder plate I9 and seeder plate II10 rotate in opposite directions, returning to the closed state. This intermittent seeding operation of potato plots is performed continuously in this cycle.
