When the turntable 20 rotates, the lever 21 can shift the baffle rod 26 during the rotation process;

[0045] The seed discharge pipe 13 and the fertilizer discharge pipe 18 are sequentially arranged between the double disc furrow opener 2 and the soil cover 3;

[0046] The frame 1 is also provided with a reduction box 28, a seeding power shaft 29 and a spot-discharging power shaft 30, which are both mounted on the frame 1 in a rotatable manner, and the reduction box 28 is connected to the seeding power shaft 29 and the spot-discharging power shaft 30 through a power transmission mechanism, the eyelet wheel 14 is mounted on the seeding power shaft 29, and the turntable 20 is mounted on the spot-discharging power shaft 30; Figure 3 As shown, the specific structure of the power transmission mechanism is as follows: a transmission shaft 31 is installed on the frame 1, the reduction box 28 is connected to the transmission shaft 31 through a bevel gear transmission pair 32, the transmission shaft 31 is connected to the seeding power shaft 29 through a first belt transmission pair 33, and the seeding power shaft 29 is connected to the spot-seeding power shaft 30 through a second belt transmission pair 34.

[0047] The operation process of the seeding hole spreading machine of this embodiment is as follows: the frame 1 is connected to the tractor through a three-point suspension mechanism. During the frame 1 process, the double disc furrow opener 2 is used to open furrows first, and the tractor power output shaft is connected to the reduction box 28. The reduction box 28 drives the transmission shaft 31 to rotate through the bevel gear transmission pair 32, and the transmission shaft 31 drives the seeding power shaft 29 to rotate through the first belt transmission pair 33. The seeding power shaft 29 drives the spot discharge power shaft 30 to rotate through the second belt transmission pair 34. Finally, under the drive of the seeding power shaft 29 and the spot discharge power shaft 30, the socket wheel 14 seeding device 4 and the fertilizer spot discharge device 5 start to work synchronously, and the seeds in the seed box 6 fall into the first disc shell 8 through the rectangular opening 12, the inoculation box 11 and the inoculation opening 9, and some of the seeds fall into the socket 15. As the socket wheel 14 rotates, the seeds in the socket 15 fall into the seed discharge pipe 13 through the seed discharge opening 10, and finally fall into the hole through the seed discharge pipe 13;

[0048] Secondly, the fertilizer in the fertilizer box 7 falls into the second disc shell 16 through the fertilizer discharge port 19 and the fertilizer connecting pipe 17, and the turntable 20 rotates driven by the spot discharge power shaft 30. When the spot discharge switch 22 is in the closed state, under the action of the first torsion spring 25, the spot discharge plug ball 27 blocks the upper end pipe opening of the fertilizer discharge pipe 18. As the turntable 20 rotates, the lever 21 toggles the baffle 26 when passing through the baffle 26, the spot discharge switch 22 is turned on, and the cross bar 24 rotates a certain angle on the short axis 23, so that the spot discharge plug ball 27 escapes upward from the upper end pipe opening of the fertilizer discharge pipe 18, and the upper end pipe opening of the fertilizer discharge pipe 18 is opened, and the fertilizer can enter the fertilizer discharge pipe 18, and fall into the hole from the fertilizer discharge pipe 18 for fertilization, and the fertilizer and seeds fall into one hole synchronously to complete the sowing hole operation.

[0049] In addition, in order to prevent the fertilizer in the fertilizer box 7 from being blocked during fertilization, the present embodiment may further provide a vibration mechanism 35 in the fertilizer box 7, the specific structure of which is as follows: Figure 7-9 As shown, the bottom of the fertilizer box 7 is a cone bucket structure 36, and the fertilizer discharge port 19 is arranged at the bottom of the cone bucket structure 36;

[0050] A vibration box 37 is placed in the fertilizer box 7. The bottom of the vibration box 37 is an inclined surface structure 38. One half of the inclined surface structure 38 is a fertilizer discharge part. The height of the fertilizer discharge part is lower than the other half of the inclined surface structure 38. The fertilizer discharge part is evenly distributed with a number of fertilizer holes 39. A vibration mechanism 35 is fixed at the bottom of the inclined surface structure 38. The vibration mechanism 35 includes an outer shell 40 and a motor 41. The outer shell 40 and the motor 41 are fixed to the inclined surface structure 38 at the bottom of the vibration box 37. A mounting shaft 42 is rotatably installed in the outer shell 40. Two eccentric blocks 43 are installed on the mounting shaft 42. The main shaft of the motor 41 is connected to the mounting shaft 42 through a coupling.

[0051] A crossbeam 44 is fixed on the top of the fertilizer box 7 , and a vibration spring 45 is installed between the crossbeam 44 and the vibration box 37 .

[0052] Fertilizer is contained in the vibration box 37, and the vibration box 37 is supported and placed in the fertilizer box 7. Since the bottom of the vibration box 37 is a slope structure 38, the fertilizer automatically gathers in the fertilizer discharge part and falls into the cone bucket structure 36 through the fertilizer hole 39. The vibration box 37 can vibrate under the drive of the high-speed rotating eccentric block 43, and the vibration is conducive to the discharge of fertilizer from the fertilizer hole 39, thereby avoiding blockage.

[0053] Secondly, two groups of fertilizer spot dischargers 5 can also be installed at the bottom of the fertilizer box 7. Specifically, a partition plate 46 is fixed in the cone bucket structure 36 at the bottom of the fertilizer box 7. The partition plate 46 divides the inner cavity of the cone bucket structure 36 into two fertilizer cavities. Two fertilizer discharge ports 19 are provided at the bottom of the cone bucket structure 36. The fertilizer discharge ports 19 correspond to the two fertilizer cavities of the cone bucket structure 36, and each fertilizer discharge port 19 is installed with a fertilizer spot discharger 5.

[0054] As another embodiment of the present invention, as the socket wheel 14 rotates, the seeds first enter the socket 15, and the socket wheel 14 rotates half a circle before seeding. If the seeds do not enter the socket 15 in advance, there will be a situation of missing seeds. In order to avoid the above situation, this embodiment is provided with a missing seed detector 47 and a seeding device 48. The missing seed detector 47 is used to detect whether there are seeds in the socket 15. If there are no seeds, the seeding device 48 performs reseeding. The specific structures of the two are as follows:

[0055] like Figure 10-14 As shown, the seed leakage detector 47 includes a mounting shell 49, a first linkage plate 50, a movable member 51 and a detection ball 52. A mounting port 53 is also provided on the top of the first disc shell 8. The mounting port 53 is located behind the inoculation port 9. The mounting shell 49 is fixed at the mounting port 53. A cylindrical movable cavity 54 is provided in the mounting shell 49. A long hole 55 is provided on the front side of the mounting shell 49. The long hole 55 is connected to the cylindrical movable cavity 54. The movable member 51 is located in the cylindrical movable cavity 54. The movable member 51 can move up and down in the cylindrical movable cavity 54. A reset spring 56 is also provided in the cylindrical movable cavity 54. The reset spring 56 conflicts with the upper end of the movable member 51. The detection ball 52 is installed at the lower end of the movable member 51 through a support rod 57. The detection ball 52 is placed in one of the sockets 15 after passing through the mounting port 53.

[0056] The first linkage plate 50 is located on the front outer wall of the mounting shell 49. A guide column 58 is fixed to the middle of the first linkage plate 50. The lower part of the first linkage plate 50 is fixedly connected to the movable member 51 through a fixing rod 59. The fixing rod 59 and the guide column 58 are both inserted into the long hole 55. The upper part of the first linkage plate 50 is fixed to a first shaft 60.

[0057] The reseeding device 48 includes a detection linkage rod 61 and a reseeding box 62. A seed storage hopper 63 is installed on the top of the reseeding box 62. A reseeding tube 64 is connected to the bottom of the reseeding box 62. A reseeding linkage member is installed on the reseeding box 62. The reseeding linkage member includes a second linkage plate 65, two push-pull rods 66, a reseeding conveyor belt 67, a driving shaft 68 and two driven shafts 69. The driving shaft 68 and the two driven shafts 69 are installed in the reseeding box 62 by rotation. The reseeding conveyor belt 67 is arranged on the driving shaft 68 and the two driven shafts 69. A plurality of circular grooves 70 are evenly distributed on the reseeding conveyor belt 67.

[0058] The second linkage plate 65 is located in front of the reseeding box 62, and a second shaft 71 is fixed on the second linkage plate 65. The two ends of the detection linkage rod 61 are respectively fixed on the first shaft 60 and the second shaft 71;

[0059] The end of the driving shaft 68 extends forwardly out of the reseeding box 62, and a square rotating member 72 is installed at the end of the driving shaft 68. The four corner ends of the square rotating member 72 are all ratchet structures 73. Two triangular pull plates 74 are also provided at the end of the driving shaft 68. The square rotating member 72 is located between the two triangular pull plates 74. The triangular pull plate 74 has an obtuse triangle shape. The triangular positions of the triangular pull plate 74 are respectively an obtuse angle, an upper angle and a lower angle. The triangular positions of the triangular pull plate 74 are all provided with circular holes. The triangular pull plate 74 is installed on the driving shaft 68 through the circular hole at the lower corner. The triangular pull plate 74 can rotate on the driving shaft 68. The circular hole at the upper corner of the triangular pull plate 74 is installed with a first pin shaft 75. The first pin shaft 75 can rotate in the circular hole. A second torsion spring 76 and a pawl 77 are installed on the first pin shaft 75. The second torsion spring 76 acts on the pawl 77, so that the pawl 77 always contacts the outer edge of the square rotating member 72.

[0060] The lower ends of the two push-pull rods 66 are arranged on the second shaft body 71, and the second shaft body 71 is rotatably matched with the lower ends of the push-pull rods 66. The two push-pull rods 66 form a V-shaped structure. The two triangular pull plates 74 are respectively connected to the upper ends of the push-pull rods 66, and the circular holes at the obtuse angles of the triangular pull plates 74 are installed on the upper ends of the push-pull rods 66 through the second pin shaft 78.

[0061] The entire process of missed seed detection and replanting is as follows: as the socket wheel 14 rotates, each socket 15 is detected by the detection ball 52. If there is a seed in the socket 15, the detection ball 52 will not move up and down, and the reset spring 56 is in a compressed state. If there is no seed in the socket 15, the detection ball 52 enters the socket 15 under the elastic force of the reset spring 56, and the movable member 51 moves downward in the cylindrical movable cavity 54, thereby driving the first linkage plate 50 to move vertically downward;

[0062] Then the first linkage plate 50 drives the second linkage plate 65 to move downward through the detection linkage rod 61, and the second linkage plate 65 pulls the two push-pull rods 66 downward, and the two push-pull rods 66 form a V-shaped structure. In the initial state, the seed storage hopper 63 is filled with seeds, and the seeds fall into the seed supplement box 62, and some seeds fall into the circular groove 70 of the seed supplement conveyor belt 67. Fig.13 As shown, the pawl 77 at the upper end of the left push-pull rod 66 abuts against the ratchet structure 73 on the left side of the square rotating member 72, while the pawl 77 at the upper end of the right push-pull rod 66 abuts against the ratchet structure 73 on the upper side of the square rotating member 72. As the two push-pull rods 66 are pulled downward, the triangular pull plate 74 on the left side rotates counterclockwise around the driving shaft 68 by a certain angle, and the triangular pull plate 74 on the right side rotates clockwise around the driving shaft 68 by a certain angle. The pawl 77 on the left triangular pull plate 74 pushes the ratchet structure 73 on the left side of the square rotating member 72, and the pawl 77 on the right triangular pull plate 74 slides on the outer edge of the square rotating member 72, and the square rotating member 72 starts to rotate. The driving shaft 68 rotates driven by the square rotating member 72, so that the reseeding conveyor belt 67 starts to transmit a certain distance. As the reseeding conveyor belt 67 is transmitted, the seeds in its circular groove 70 fall into the reseeding tube 64, and are replenished into the hole by the reseeding tube 64 to complete the reseeding.

[0063] As the socket wheel 14 rotates, the detection ball 52 escapes upward from the socket 15 without a seed inside, and the detection ball 52 moves upward, and finally drives the first linkage plate 50 to move upward through the movable part 51. The first linkage plate 50 moves upward through the detection linkage rod 61 and the second linkage plate 65, and the second linkage plate 65 pushes the two push-pull rods 66 upward. At this time, the pawl 77 on the right triangular pull plate 74 has just slid across the ratchet structure 73 on the right side of the square rotating part 72, and the push-pull rod 66 pushes the triangular pull plate 74 upward, and the pawl 77 on the triangular pull plate 74 pushes the ratchet structure 73 on the right side of the square rotating part 72, so that the square rotating part 72 rotates a certain angle again.
