[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described in detail below with reference to the embodiments.

[0041] A specific embodiment of the lateral horizontal application seeding hole applicator provided by the present invention:

[0042] like Figure 1-3 As shown, a side-position flat application seeding and hole application machine includes a frame 1. A double-disc furrow opener 2 and a soil coverer 3 are set at the bottom of the frame 1. A seed metering device 4, a fertilizer spot metering device 5, a seed box 6 and a fertilizer box 7 are installed on the frame 1. The seed metering device 4 is installed at the bottom of the seed box 6 and the fertilizer spot metering device 5 is installed at the bottom of the fertilizer box 7.

[0043] like Figure 4 and Figure 5 As shown, the seed metering device 4 includes a first disc housing 8. The top and bottom of the first disc housing 8 are respectively provided with an inoculation port 9 and a seed metering port 10. An inoculation box 11 is installed at the inoculation port 9. The bottom of the seed box 6 is provided with a rectangular opening 12. The inoculation box 11 is installed at the rectangular opening 12. A seed metering tube 13 is connected to the seed metering port 10. A seed metering wheel 14 is provided inside the first disc housing 8. The seed metering wheel 14 can rotate inside the first disc housing 8. A plurality of seed holes 15 are evenly provided on the outer edge of the seed metering wheel 14.

[0044] like Figure 6As shown, the fertilizer dispenser 5 includes a second disc housing 16. A fertilizer receiving pipe 17 and a fertilizer discharging pipe 18 are connected to the top and bottom of the second disc housing 16, respectively. A fertilizer discharging port 19 is opened at the bottom of the fertilizer tank 7, and the fertilizer receiving pipe 17 is fixed to the fertilizer discharging port 19. A turntable 20 is installed inside the second disc housing 16, and the turntable 20 can rotate within the second disc housing 16. A lever 21 is fixed to the outer edge of the turntable 20. A discharging switch 22 is installed at the lower part of the second disc housing 16. The discharging switch 22 includes a short shaft 23 and a crossbar 24. The short shaft 23... The crossbar 24 is fixed in the lower part of the second disc housing. A circular hole is provided in the middle of the crossbar 24. The short shaft 23 passes through the circular hole of the crossbar 24 and can rotate on the short shaft 23. A first torsion spring 25 is provided on the short shaft 23. The first torsion spring 25 acts on the crossbar 24. A stop bar 26 and a dot-filling ball 27 are fixed on the crossbar 24. The dot-filling ball 27 is installed at the end of the crossbar 24 and is located at the upper end of the fertilizer discharge pipe 18. When the turntable 20 rotates, the lever 21 can move the stop bar 26 during the rotation.

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

[0046] The frame 1 is also equipped with a reduction gearbox 28, a seeding power shaft 29, and a spot-drilling power shaft 30. Both the seeding power shaft 29 and the spot-drilling power shaft 30 are rotatably mounted on the frame 1. The reduction gearbox 28 is connected to the seeding power shaft 29 and the spot-drilling power shaft 30 via 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-drilling power shaft 30. Figure 3 As shown, the specific structure of the power transmission mechanism is as follows: a drive shaft 31 is installed on the frame 1, a reduction gearbox 28 is connected to the drive shaft 31 through a bevel gear transmission pair 32, the drive 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 point-discharge power shaft 30 through a second belt transmission pair 34.

[0047] The operation process of the seeding hole applicator in this embodiment is as follows: The frame 1 is connected to the tractor through a three-point suspension mechanism. During the operation of the frame 1, the double-disc furrow opener 2 first opens the furrow. The tractor's power output shaft is connected to the reduction gearbox 28. The reduction gearbox 28 drives the transmission shaft 31 to rotate through the bevel gear transmission pair 32. The transmission shaft 31 drives the seed metering power shaft 29 to rotate through the first belt transmission pair 33. The seed metering power shaft 29 drives the spot metering power shaft 30 to rotate through the second belt transmission pair 34. Finally, under the drive of the seed metering power shaft 29 and the spot metering power shaft 30, the seed metering device 4 and the fertilizer spot metering device 5 start to work synchronously. 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 port 9. Some of the seeds fall into the holes 15. As the seed metering wheel 14 rotates, the seeds in the holes 15 fall into the seed metering tube 13 through the seed metering port 10, and finally fall into the hole through the seed metering tube 13.

[0048] Secondly, the fertilizer in the fertilizer box 7 falls into the second disc housing 16 through the fertilizer outlet 19 and the fertilizer receiving pipe 17. The turntable 20 rotates under the drive of the puncture power shaft 30. When the puncture switch 22 is in the closed state, under the force of the first torsion spring 25, the puncture stopper ball 27 blocks the upper end of the fertilizer outlet pipe 18. As the turntable 20 rotates, the lever 21 moves the stop lever 26 when it passes the stop lever 26, and the puncture switch 22 is opened. The crossbar 24 rotates a certain angle on the short shaft 23, so that the puncture stopper ball 27 comes out upward from the upper end of the fertilizer outlet pipe 18. The upper end of the fertilizer outlet pipe 18 is opened, and the fertilizer can enter the fertilizer outlet pipe 18 and fall into the hole for fertilization. The fertilizer and seeds fall into the hole at the same time, completing the sowing and hole application operation.

[0049] In addition, to prevent fertilizer from clogging the fertilizer tank 7 during fertilization, this embodiment can also install a vibration mechanism 35 inside the fertilizer tank 7, with the specific structure as follows: Figure 7-9 As shown, the bottom of the fertilizer box 7 is a cone-shaped structure 36, and the fertilizer outlet 19 is located at the bottom of the cone-shaped structure 36.

[0050] A vibrating box 37 is placed inside the fertilizer box 7. The bottom of the vibrating box 37 is a sloping structure 38. One half of the sloping structure 38 is a fertilizer discharge section, and the height of the fertilizer discharge section is lower than that of the other half of the sloping structure 38. The fertilizer discharge section is evenly distributed with several fertilizer holes 39. A vibration mechanism 35 is fixed at the bottom of the sloping 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 sloping structure 38 at the bottom of the vibrating box 37. An installation shaft 42 is rotatably installed inside the outer shell 40. Two eccentric blocks 43 are installed on the installation shaft 42. The main shaft of the motor 41 is connected to the installation shaft 42 through a coupling.

[0051] A crossbeam 44 is fixed to 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 vibrating box 37, which is supported and placed inside the fertilizer box 7. Since the bottom of the vibrating box 37 is a sloping structure 38, the fertilizer automatically gathers in the fertilizer discharge section and falls into the conical hopper structure 36 through the fertilizer hole 39. The vibrating box 37 can vibrate under the drive of the high-speed rotating eccentric block 43. The vibration helps the fertilizer to be discharged from the fertilizer hole 39, thereby avoiding blockage.

[0053] Secondly, two sets of fertilizer dispensers 5 can be installed at the bottom of the fertilizer tank 7. Specifically, a partition plate 46 is fixed inside the cone-shaped structure 36 at the bottom of the fertilizer tank 7. The partition plate 46 divides the inner cavity of the cone-shaped structure 36 into two fertilizer chambers. Two fertilizer discharge ports 19 are provided at the bottom of the cone-shaped structure 36. The fertilizer discharge ports 19 correspond to the two fertilizer chambers of the cone-shaped structure 36. Each fertilizer discharge port 19 is equipped with a fertilizer dispenser 5.

[0054] In another embodiment of the present invention, as the seed-filling wheel 14 rotates, the seeds first enter the seed-filling holes 15. After the seed-filling wheel 14 rotates half a turn, the seeds are distributed. If the seeds do not enter the seed-filling holes 15 beforehand, seed leakage will occur. To avoid this situation, this embodiment provides a seed leakage detector 47 and a seed replenisher 48. The seed leakage detector 47 is used to detect whether there are seeds in the seed-filling holes 15. If there are no seeds, the seed replenisher 48 replenishes the seeds. The specific structures of the two are as follows:

[0055] like Figure 10-14 As shown, the missed seed detector 47 includes a mounting shell 49, a first linkage plate 50, a movable component 51, and a detection ball 52. The top of the first disc shell 8 is also provided with a mounting port 53, which 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 inside the mounting shell 49. An elongated hole 55 is opened on the front side of the mounting shell 49, which is connected to the cylindrical movable cavity 54. The movable component 51 is located inside the cylindrical movable cavity 54 and can move up and down inside the cylindrical movable cavity 54. A return spring 56 is also provided inside the cylindrical movable cavity 54. The return spring 56 abuts against the upper end of the movable component 51. The detection ball 52 is installed at the lower end of the movable component 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 post 58 is fixed in the middle of the first linkage plate 50. The lower part of the first linkage plate 50 is fixedly connected to the movable part 51 through a fixing rod 59. Both the fixing rod 59 and the guide post 58 are inserted into the elongated hole 55. A first shaft 60 is fixed in the upper part of the first linkage plate 50.

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

[0058] The second linkage plate 65 is located in front of the replanting box 62. The 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 drive shaft 68 extends forward into the replanting box 62. A square rotating component 72 is installed at the end of the drive shaft 68. The four corners of the square rotating component 72 are all ratchet structures 73. Two triangular pull plates 74 are also provided at the end of the drive shaft 68. The square rotating component 72 is located between the two triangular pull plates 74. The triangular pull plates 74 are obtuse triangles. The triangular positions of the triangular pull plates 74 are obtuse, upper, and lower. A round hole is opened at each of the triangular positions of the triangular pull plates 74. The triangular pull plates 74 are installed on the drive shaft 68 through the round hole at the lower corner. The triangular pull plates 74 can rotate on the drive shaft 68. A first pin 75 is installed in the round hole at the upper corner of the triangular pull plates 74. The first pin 75 can rotate in the round hole. A second torsion spring 76 and a pawl 77 are installed on the first pin 75. The second torsion spring 76 acts on the pawl 77, so that the pawl 77 always abuts against the outer edge of the square rotating component 72.

[0060] The lower ends of the two push-pull rods 66 are mounted on the second shaft 71, and the second shaft 71 and the lower ends of the push-pull rods 66 are rotatably coupled. The two push-pull rods 66 form a V-shaped structure. Two triangular pull plates 74 are respectively connected to the upper ends of the push-pull rods 66, and the round 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 78.

[0061] The entire process of missing seed detection and replanting is as follows: As the seed-filling wheel 14 rotates, each seed-filling hole 15 is detected by the detection ball 52. If there is a seed in the seed-filling hole 15, the detection ball 52 will not move up or down, and the return spring 56 will be in a compressed state. If there is no seed in the seed-filling hole 15, the detection ball 52 will enter the seed-filling hole 15 under the elastic force of the return spring 56, and the movable part 51 will move downward in the cylindrical movable cavity 54, thereby driving the first linkage plate 50 to move downward vertically.

[0062] Next, the first linkage plate 50 drives the second linkage plate 65 downward through the detection linkage rod 61. The second linkage plate 65 pulls down two push-pull rods 66, which form a V-shaped structure. In the initial state, the seed storage hopper 63 contains seeds, which fall into the replanting box 62. Some seeds fall into the circular groove 70 of the replanting conveyor belt 67. Figure 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 part 72, while the pawl 77 at the upper end of the right push-pull rod 66 abuts against the ratchet structure 73 above the square rotating part 72. As the two push-pull rods 66 are pulled down, the left triangular pull plate 74 rotates counterclockwise around the drive shaft 68 by a certain angle, and the right triangular pull plate 74 rotates clockwise around the drive 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 part 72, and the pawl 77 on the right triangular pull plate 74 slides on the outer edge of the square rotating part 72. The square rotating part 72 begins to rotate, and the drive shaft 68 rotates under the drive of the square rotating part 72. Thus, the replanting conveyor belt 67 begins to travel a certain distance. As the replanting conveyor belt 67 is driven, the seeds in its circular groove 70 fall into the replanting tube 64 and are replanted into the hole by the replanting tube 64, completing the replanting.
