Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery, in particular to an intelligent agricultural planting and sowing machine. BACKGROUND

[0002] The sowing machine is an agricultural machine, which is mainly used for uniformly and efficiently sowing seeds into the soil to replace the traditional manual sowing and improve the agricultural production efficiency. The existing sowing machine includes a drill, a dibbler and a broadcaster, wherein: The drill is used for sowing seeds in rows, which is suitable for densely planted crops such as wheat and grains; The dibbler is used for single-grain sowing at fixed intervals, which saves seeds and avoids thinning, such as corn and soybeans.

[0003] The broadcaster is used for throwing seeds over a large area, which has low uniformity but high efficiency, such as pasture and green manure; However, the existing sowing machine has some defects, for example: The drill can only sow seeds in rows and cannot sow seeds by dibbling or broadcasting. The dibbler can only sow seeds by dibbling and cannot sow seeds by drilling or broadcasting. The broadcaster can only sow seeds by broadcasting and cannot sow seeds by dibbling or drilling. In summary, the existing sowing machine cannot combine the functions of drilling, dibbling and broadcasting, and cannot switch between the three functions.

[0004] Therefore, the present application provides an intelligent agricultural planting and sowing machine to solve the above problems. SUMMARY

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present application provides an intelligent agricultural planting and sowing machine to solve the problem that the existing sowing machine cannot combine the functions of drilling, dibbling and broadcasting and cannot switch between the three functions.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: An intelligent agricultural planting and sowing machine, comprising a mechanical body frame, a rotating frame, a seed throwing disc and a seed positioning cylinder. The mechanical body frame: the upper end of the mechanical body frame is fixedly connected with a hopper, the lower side of the hopper is fixedly and linearly connected with a pneumatic seed metering device, and the seed metering end of the pneumatic seed metering device is fixedly connected with a seed metering pipe. The rotating frame: the rotating frame is fixedly connected in the mechanical body frame and can rotate, and the rotating frame is linearly and rotatably connected with a fan-shaped frame, and a control assembly is installed between the rotating frame and the fan-shaped frame to drive the fan-shaped frame to rotate. Seed-spinning tray: The seed-spinning tray rotates inside the fan-shaped frame. The other end of the seed-discharging tube is connected to the seed-spinning tray. The side of the seed-spinning tray has a rotating seat, and the side of the rotating seat is connected to a vertical push rod. The vertical push rod moves up and down through the horizontal slide frame. The horizontal slide frame is inserted horizontally inside the horizontal push frame. The end of the horizontal push frame has a rotating block for installation. The rotating block for installation is fixed inside the swing arm. A power component is installed inside the rotating frame. The center of the swing arm is fixedly connected to the output end of the power component. The power component drives the swing arm to move back and forth. The seed-throwing tray is hollow inside and has a seed-throwing port at the end. A split section is integrally formed in the center of the seed-throwing port to divide the seed-throwing port into an upper seed-throwing port and a lower seed-throwing port. An arc-shaped baffle is movably inserted around the center of the seed-throwing tray inside the split section. An extension section is provided at the lower end of the arc-shaped baffle, which blocks the lower seed-throwing port. A support hole is provided at one end of the arc-shaped baffle located inside the split section. An inner rotating column moves through the opening, and a push rod is fixedly connected to the side of the end of the inner rotating column. The push rod is located in the support hole. A spring is movably clamped between the inner rotating column and the opening. A support seat is fixedly connected to the end of the inner rotating column outside the opening. An arc-shaped limiting rod is fixedly connected inside the support seat. A seed positioning cylinder slides inside the support seat, and the arc-shaped limiting rod moves through the seed positioning cylinder. The seed positioning cylinder has a feed inlet at the middle and a discharge outlet at the bottom. A stop bar is fixedly connected inside the feed inlet. The stop bar pushes the extension and the arc-shaped baffle to move upward. The feed inlet of the seed positioning cylinder is located directly below the lower seed throwing port of the seed throwing disc. With the above technical solution, when the seed-throwing disc is in a horizontal state and the seed positioning cylinder is in a vertical state, the seeds can be thrown out from the upper and lower seed-throwing ports of the seed-throwing disc at the same time, thus realizing the sowing function. When the seed-splitting disc is in a vertical position and the seed positioning cylinder is in a horizontal position, the seeds can be flung out from the lower seed-splitting port of the seed-splitting disc. Since the seed-splitting disc is in a vertical position, the seeds are sown in a line, thus achieving the row sowing function. When the seed-throwing tray is in a vertical position and the seed positioning cylinder is in a vertical position, the arc-shaped baffle and the extension can intermittently open the lower seed-throwing port, thereby intermittently discharging the seeds. The seeds are also directed into the seed positioning cylinder and discharged from the seed positioning cylinder, that is, the seeds are discharged after being placed on the ground, thus realizing the spot sowing function. When the seed-throwing tray is horizontal and the seed positioning cylinder is vertical, and when the seed-throwing tray is vertical and the seed positioning cylinder is horizontal, the push rod pushes the arc-shaped baffle from inside the support hole, so that the upper and lower seed-throwing ports of the seed-throwing tray are always open, avoiding affecting broadcasting and row sowing. When the seed-throwing tray is vertical and the seed positioning cylinder is vertical, the upper seed-throwing port of the seed-throwing tray can be in an alternating open and closed state. The power unit drives the seed-throwing disc to rotate through the swing arm, horizontal push frame, horizontal slide frame, vertical push rod and rotating seat. Through the forward and backward movement of the horizontal push frame, the left and right movement of the horizontal slide frame, the up and down movement of the vertical push rod and the rotation of the rotating seat, the power transmission can still drive the seed-throwing disc to rotate after the seed-throwing disc changes direction, thus realizing the function of multi-directional power transmission. The rotating frame can rotate, which allows the seed trays to revolve, increasing or decreasing the lateral spacing between the seed trays in a row, thereby adjusting the spacing of the seed trays and the planting spacing for broadcasting, row sowing, and spot sowing.

[0007] Preferably, the control assembly includes a rotating column, a driven gear, an active gear plate, a transverse rod, and a first screw. One end of the rotating column is fixedly connected to the end of the sector frame, and the other end of the rotating column rotates through the rotating frame. A section of the rotating column located inside the rotating frame is fixedly connected through the driven gear. The driven gear meshes with the active gear plate. The active gear plate is fixedly connected to the lower part of the transverse rod. The transverse rod movably passes through the rotating frame. A first screw is threaded through the end of the transverse rod, and the other end of the first screw rotates inside the rotating frame. The above technical solution involves rotating the first screw to move the transverse rod laterally, and then using the power transmission of the active gear plate and the passive gear to drive the rotating column and the sector frame to rotate. After the first screw stops rotating, the rotating column and the sector frame can be fixed, thereby controlling the rotation, fixation and rotation angle of the sector frame.

[0008] Preferably, the side circular array of the support base is provided with slots, and the side circular array of the split portion is provided with inserts, the inserts being movably inserted into the slots of the support base; With the above technical solution, the insert block can be inserted into the slot to fix the support base, which can also initially fix the seed positioning cylinder on the support base and prevent the support base and seed positioning cylinder from rotating at will.

[0009] Preferably, an L-shaped folding column is fixedly connected to the center of the mechanical body frame, and an arc-shaped support frame is fixedly connected to both ends of the mechanical body frame in the lateral direction. The two arc-shaped support frames are symmetrically arranged, and the center of the two arc-shaped support frames is on the same straight line as the lower center of the L-shaped folding column. The center of the rotating frame rotates at the lower center of the L-shaped folding column, and the two ends of the rotating frame rotate within the two arc-shaped support frames respectively. A second screw is fixedly connected to the end of the rotating frame. After the second screw moves out of the arc-shaped support frame, a nut is threaded on it. The nut presses against the arc-shaped support frame to fix the rotating frame. Through the above technical solution, the L-shaped folding column is used to support the rotating frame, and the nut presses against the arc-shaped support frame to fix the rotating frame, thereby controlling the rotation, fixation and rotation angle of the rotating frame.

[0010] Preferably, the upper end of the seed positioning cylinder is provided with an abutment part, and a limiting rod is installed on the side of the fan-shaped frame away from the seed discharge tube. The limiting rod is located directly below the abutment part, and when the abutment part moves down, the limiting rod pushes the abutment part upward. With the above technical solution, when the contact part moves downward, the limiting rod pushes upward against the contact part, thus preventing the seed positioning cylinder from falling. During seeding, if the limiting rod does not push against the contact part, the lower end of the seed positioning cylinder will need to fall to the ground before it stops rotating. When the height of the seed throwing tray and the seed positioning cylinder changes due to the revolution of the rotating frame, the seeding function will be unstable. However, by setting the limiting rod to push against the contact part, the seed positioning cylinder can stop rotating without falling to the ground. That is, regardless of the height of the seed throwing tray and the seed positioning cylinder, the upward movement of the seed positioning cylinder can be controlled, ensuring the stability of the seeding process.

[0011] Preferably, a protrusion is provided at the middle of the seed positioning cylinder, and an arc-shaped bracket is fixedly connected to the side of the seed throwing disc where the limiting rod is installed. The center of the arc-shaped bracket is on the same straight line as the rotation center of the inner rotating column. The lower end of the arc-shaped bracket extends vertically downward. When the seed positioning cylinder rotates to be perpendicular to the seed throwing disc, the arc-shaped bracket abuts against the protrusion, causing the protrusion to move along the inner side of the arc-shaped bracket. With the above technical solution, since the seed positioning cylinder needs to rotate relative to the seed throwing plate, and the protrusion moves along the inner side of the arc-shaped bracket, the rotation trajectory of the seed positioning cylinder can be restricted, and the seed positioning cylinder can be prevented from moving relative to the seed throwing plate after rotation. That is, the upper end of the seed positioning cylinder is restricted by the arc-shaped limiting rod and the support seat, and the middle end is restricted by the arc-shaped bracket, which can increase the stability of the seed positioning cylinder.

[0012] Preferably, the limiting rod moves up and down within the sector frame, and a screw rotates through the sector frame, with the screw thread passing through the limiting rod; The above technical solution allows for adjustment of the height of the limiting rod and ensures that the limiting rod remains fixed after adjustment.

[0013] Preferably, the power assembly includes a directional rod, a first pin, a first transmission rod, a motor, a second transmission rod, and a third transmission rod. The motor is fixedly connected to the end of the rotating frame. The output end of the motor rotates through the rotating frame and is then fixedly connected to the third transmission rod. The other end of the third transmission rod passes through a rotating shaft and is rotatably connected to the second transmission rod. The other end of the second transmission rod rotates within one end of the first transmission rod via the rotating shaft. The other end of the first transmission rod movably passes through the rotating frame and rotates within one end of the directional rod. A first pin is inserted between the first transmission rod and the directional rod. The other end of the directional rod movably passes out of the rotating frame and is then fixedly connected to a swing rod. Through the above technical solution, the output power of the motor drives the swing arm to move back and forth through the third transmission rod, the second transmission rod, the first transmission rod, and the directional rod, thereby providing power for the movement of the swing arm. Furthermore, the pin can be pulled out to rotate the directional rod 180° to change the direction of the swing arm, thereby changing the height of the horizontal slide and the horizontal push frame. Since the height of the rotating seat and the vertical push rod are different when the seed-throwing disc is in a horizontal state and when it is in a vertical state, changing the height of the horizontal slide and the horizontal push frame can make the height of the horizontal slide and the horizontal push frame consistent with the height of the rotating seat and the vertical push rod.

[0014] Preferably, it also includes a power supply and a controller, with the output of the power supply electrically connected to the controller, and the output of the controller electrically connected to the input of the motor and the pneumatic seed metering device.

[0015] The beneficial effects of this invention are as follows: 1. When the seed-throwing tray is in a horizontal position and the seed positioning cylinder is in a vertical position, the seeds can be thrown horizontally from the upper and lower seed-throwing ports of the seed-throwing tray at the same time to achieve the sowing function. 2. When the seed-throwing tray is in a vertical position and the seed positioning cylinder is in a horizontal position, the seeds can be thrown out from the lower seed-throwing port of the seed-throwing tray. Since the seed-throwing tray is in a vertical position, the seeds are sown in a line, realizing the row sowing function. 3. When the seed-throwing tray is in a vertical position and the seed positioning cylinder is in a vertical position, the arc-shaped baffle and the extension can intermittently open the lower seed-throwing port, thereby intermittently discharging the seeds. The seeds are directionally guided into the seed positioning cylinder and discharged from the seed positioning cylinder, that is, the seeds are discharged after being placed on the ground, realizing the spot sowing function. 4. The rotating frame can be rotated, which allows the seed trays to revolve, increasing or decreasing the lateral spacing between a row of seed trays, thereby adjusting the spacing of the seed trays and the planting spacing for broadcasting, row sowing, and spot sowing.

[0016] In summary, this device combines broadcasting, row sowing, and spot sowing functions, and can switch between the three functions, making it widely applicable. Furthermore, the sowing spacing can be adjusted when performing any function, making it more practical. Attached Figure Description

[0031] The following will refer to the attached reference. Figures 1 to 13The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] As attached Figure 1 - Appendix Figure 13 As shown, an intelligent agricultural planting and sowing machine includes a mechanical frame 2, a rotating frame 6, a seed-spinning disc 14, and a seed positioning cylinder 16. Mechanical frame 2: See appendix Figure 3 The lower end of the mechanical frame 2 has rotating wheels and a hook at the rear end for attaching it to an external vehicle for movement. The upper end of the mechanical frame 2 is fixedly connected to a funnel 1, which contains seeds. (See attached document.) Figure 1 A pneumatic seed metering device 3 is fixedly connected to the lower side of the funnel 1 in a linear array. The funnel 1 is connected to the seed inlet of the pneumatic seed metering device 3, allowing the seeds in the funnel 1 to flow into the pneumatic seed metering device 3. A seed metering tube 4 is fixedly connected to the seed metering end of the pneumatic seed metering device 3 to discharge the seeds in the pneumatic seed metering device 3 into the seed metering tube 4. (See attached diagram) Figure 1 An L-shaped folding column 41 is fixedly connected to the center of the mechanical body frame 2. An arc-shaped support frame 5 is fixedly connected to both ends of the horizontal direction of the mechanical body frame 2. The two arc-shaped support frames 5 are symmetrically arranged, and the center of the two arc-shaped support frames 5 is on the same straight line as the lower center of the L-shaped folding column 41. Rotating frame 6: The center of rotation of rotating frame 6 is at the lower center of L-shaped folding column 41. Both ends of rotating frame 6 rotate within two arc-shaped support frames 5 respectively. (See appendix) Figure 4 A second screw 20 is fixedly connected to the end of the rotating frame 6. The second screw 20 extends out of the arc-shaped support frame 5 and is threaded with a nut 21. The nut 21 presses against the arc-shaped support frame 5 to fix the rotating frame 6. (See attached diagram) Figure 1 Within the rotating frame 6, a sector frame 12 rotates in a linear array. A control component is installed between the rotating frame 6 and the sector frame 12. The control component drives the sector frame 12 to rotate and controls the rotation angle. Seed Discharge Plate 14: See Appendix Figure 1 The rotation of the seed-throwing disc 14 occurs within the sector-shaped frame 12, and the rotation direction of the seed-throwing disc 14 and the rotation direction of the sector-shaped frame 12 are both on a vertical plane and perpendicular to each other. (See attached diagram.) Figure 2 A limiting post 18 is fixedly connected to the side of the seed-throwing tray 14. An arc-shaped hole is provided at the end of the sector frame 12, and the center of the arc-shaped hole is on the same straight line as the rotation center of the seed-throwing tray 14. The limiting post 18 is located in the arc-shaped hole to help limit the rotation trajectory of the seed-throwing tray 14 and prevent the seed-throwing tray 14 from falling out of the sector frame 12. See Appendix. Figure 1 and attached Figure 7The other end of the seed metering tube 4 rotates through the center of the side of the fan-shaped frame 12 and the seed-throwing tray 14 and then connects into the seed-throwing tray 14. The seed metering tube 4 is made of plastic, which is soft and deformable. When the seed-throwing tray 14 rotates, the seed metering tube 4 can deform to adapt and participate in the process. Figure 1 Appendix Figure 8 and attached Figure 9 The side of the seed-throwing disc 14 has a rotating seat 39, and the side of the rotating seat 39 is rotatably connected to a vertical push rod 11. The vertical push rod 11 is always in a vertical state. The vertical push rod 11 moves up and down through the horizontal slide 37. The horizontal slide 37 is inserted horizontally into the horizontal push frame 9. The end of the horizontal push frame 9 has a rotating mounting block 38. A second pin 40 passes between the rotating mounting block 38 and the swing rod 10, so that the rotating mounting block 38 is fixed in the swing rod 10. The center of the swing rod 10 is fixedly connected to the output end of the power component 22. See appendix Figure 6 Appendix Figure 7 and attached Figure 11 The seed-throwing tray 14 is hollow inside and has a seed-throwing port at its end. A split section 24 is integrally formed in the center of the seed-throwing port to divide the seed-throwing port into an upper seed-throwing port and a lower seed-throwing port. An arc-shaped baffle 23 is movably inserted around the center of the seed-throwing tray 14 inside the split section 24. An extension section 32 is provided at the lower end of the arc-shaped baffle 23, which blocks the lower seed-throwing port. A support hole 29 is provided at one end of the arc-shaped baffle 23 located inside the split section 24. See appendix Figure 6 Appendix Figure 7 and attached Figure 11 An inner rotating column 28 moves through the opening 24. A push rod 27 is fixedly connected to the side of the end of the inner rotating column 28. The push rod 27 revolves around the rotation center of the inner rotating column 28. The push rod 27 is located in the support hole 29. When the push rod 27 revolves with the inner rotating column 28, it pushes the arc-shaped baffle 23 upward from the support hole 29. A spring 26 is movably clamped between the inner rotating column 28 and the opening 24. A support seat 31 is fixedly connected to the end of the inner rotating column 28 outside the opening 24. The support base 31 has slots arranged in a circular array on its side, and the split part 24 has inserts 25 arranged in a circular array on its side. The inserts 25 are movably inserted into the slots of the support base 31. An arc-shaped limiting rod 30 is fixedly connected inside the support base 31. The center of the arc-shaped limiting rod 30 is on the same straight line as the rotation center of the seed throwing disc 14. A seed positioning cylinder 16 slides inside the support base 31. The arc-shaped limiting rod 30 moves through the seed positioning cylinder 16, allowing the seed positioning cylinder 16 to move along the arc-shaped limiting rod 30. See appendix Figure 6 Appendix Figure 7 and attached Figure 11The seed positioning cylinder 16 has a feed inlet at the middle and a discharge outlet at the lower end. A stop bar 33 is fixedly connected inside the feed inlet. The stop bar 33 pushes the extension 32 and the arc-shaped baffle 23 to move upward. The feed inlet of the seed positioning cylinder 16 is located directly below the lower seed throwing port of the seed throwing disc 14. See appendix Figure 1 and attached Figure 2 The seed positioning cylinder 16 has an abutment part 17 at its upper end. A limiting rod 15 is fixedly connected to the side of the fan-shaped frame 12 away from the seed discharge tube 4. The limiting rod 15 is located directly below the abutment part 17. When the abutment part 17 moves down, the limiting rod 15 pushes the abutment part 17 upward. The limiting rod 15 is fixed as follows: the limiting rod 15 moves up and down inside the sector frame 12. A screw passes through the sector frame 12 and the screw thread passes through the limiting rod 15. When the screw is rotated, the limiting rod 15 moves up and down. After the limiting rod 15 moves upward, the contact part 17 and the seed positioning cylinder 16 can contact the contact part 17 when they move downward a smaller distance, and thus push against the contact part 17 and the seed positioning cylinder 16 upward. Similarly, after the limiting rod 15 moves downward, the contact part 17 and the seed positioning cylinder 16 can contact the contact part 17 when they move downward a larger distance, and thus push against the contact part 17 and the seed positioning cylinder 16 upward. See appendix Figure 1 and attached Figure 2 A protrusion 19 is provided at the middle of the seed positioning cylinder 16. An arc-shaped bracket 13 is fixedly connected to the side of the seed throwing tray 14 where the limiting rod 15 is installed. The center of the arc-shaped bracket 13 is on the same straight line as the rotation center of the inner rotating column 28. The lower end of the arc-shaped bracket 13 extends vertically downward. When the seed positioning cylinder 16 rotates to be perpendicular to the seed throwing tray 14, the arc-shaped bracket 13 abuts against the protrusion 19, causing the protrusion 19 to move along the inner side of the arc-shaped bracket 13.

[0033] As attached Figure 1 Appendix Figure 6 and attached Figure 7 As shown, the control assembly includes a rotating column 34, a driven gear 35, a driving gear plate 36, a transverse rod 8, and a first screw 7. One end of the rotating column 34 is fixedly connected to the end of the sector frame 12, and the other end of the rotating column 34 rotates through the rotating frame 6. A section of the rotating column 34 located inside the rotating frame 6 is fixedly connected through the driven gear 35. The driven gear 35 meshes with the driving gear plate 36. The driving gear plate 36 is fixedly connected to the lower part of the transverse rod 8. The transverse rod 8 moves through the rotating frame 6. The first screw 7 is threaded through the end of the transverse rod 8. The other end of the first screw 7 rotates inside the rotating frame 6. The control component works as follows: when the first screw 7 is manually rotated in both directions, the first screw 7 drives the transverse rod 8 to move horizontally left and right. The transverse rod 8 drives the active gear plate 36 to move horizontally left and right. The active gear plate 36 drives the passive gear 35 to rotate in both directions through inter-tooth meshing. The passive gear 35 drives the rotating column 34 to rotate. The rotating column 34 drives the sector frame 12 to rotate. Similarly, when the first screw 7 is stopped rotating, the rotating column 34 stops driving the sector frame 12 to rotate, so that the sector frame 12 is in a fixed state.

[0034] As attached Figure 4 and attached Figure 9 As shown, the power assembly 22 includes a directional rod 2201, a first pin 2202, a first transmission rod 2203, a motor 2204, a second transmission rod 2205, and a third transmission rod 2206. The motor 2204 is fixedly connected to the end of the rotating frame 6. The output end of the motor 2204 rotates through the rotating frame 6 and is then fixedly connected to the third transmission rod 2206. The other end of the third transmission rod 2206 passes through a rotating shaft and is rotatably connected to the second transmission rod 2205. The other end of the transmission rod 2205 rotates through a shaft into one end of the first transmission rod 2203. The other end of the first transmission rod 2203 is movably inserted into the rotating frame 6. The other end of the first transmission rod 2203 rotates into one end of the directional rod 2201. A first pin 2202 is inserted between the first transmission rod 2203 and the directional rod 2201. The first pin 2202 is made of iron wire and can be bent. The other end of the directional rod 2201 is movably inserted out of the rotating frame 6 and then fixedly connected to the swing rod 10. The power assembly 22 operates as follows: after the motor 2204 is powered on, it drives the third transmission rod 2206 to rotate. The third transmission rod 2206 drives the first transmission rod 2203 to move through the second transmission rod 2205. The first transmission rod 2203 drives the guide rod 2201 to move laterally. The guide rod 2201 drives the swing arm 10 to move laterally. In addition, when the swing arm 10 needs to rotate 180°, the first pin 2202 can be straightened and then pulled out, so that the guide rod 2201 is in a free rotation state. The guide rod 2201 and the swing arm 10 can be rotated 180°. After that, the first pin 2202 is reinserted and then bent, so that the first transmission rod 2203 can continue to drive the guide rod 2201 to move laterally.

[0035] As attached Figure 12 As shown, it also includes a power supply 42 and a controller 43. Both the power supply 42 and the controller 43 are fixed on the external vehicle body. The output end of the power supply 42 is electrically connected to the controller 43, and the output end of the controller 43 is electrically connected to the input end of the motor 2204 and the pneumatic seed metering device 3.

[0036] The working principle of this device is as follows: The controller 43 controls the pneumatic seed metering device 3 to work, so that the seeds in the funnel 1 are discharged into the seed metering tube 4, and the seeds flow from the seed metering tube 4 into the seed throwing tray 14. The seed-spinning disc 14 and the seed positioning cylinder 16 are rotated according to the needs of row sowing, spot sowing, and broadcast sowing. Rotate the seed-throwing tray for 14 hours: According to the above-mentioned operating method of the control component, the control component drives the sector frame 12 to rotate, and the sector frame 12 drives the seed-throwing disc 14 to rotate, so that the seed-throwing disc 14 is in a vertical or horizontal state. When the seed positioning cylinder is rotated 16: Keep the seed-throwing tray 14 in a fixed state, pull the seed positioning cylinder 16 away from the seed-throwing tray 14. The seed positioning cylinder 16 drives the support base 31 to move, the spring 26 is compressed, and the insert 25 leaves the slot of the support base 31. Then rotate the seed positioning cylinder 16, which drives the support base 31 to rotate, causing the inner rotating column 28 to rotate. After rotation, release the seed positioning cylinder 16, the spring 26 returns to its original state and pushes the inner rotating column 28, so that the seed positioning cylinder 16 and the support base 31 are close to the seed-throwing tray 14 again, and the insert 25 is inserted into the slot to complete the fixation. At the same time as the seed positioning cylinder 16 is rotated, the protrusion 19 moves along the arc-shaped bracket 13, so that the lower end of the seed positioning cylinder 16 is restricted by the arc-shaped bracket 13 and the upper end is restricted by the arc-shaped limiting rod 30, thus achieving the purpose of auxiliary fixation. The cyclic rotation mode of the seed-throwing disc 14 is as follows: the power component 22 pushes the swing arm 10 to move back and forth, the swing arm 10 pushes the horizontal push frame 9 to move back and forth, the horizontal push frame 9 pushes the vertical push rod 11 to move back and forth by pushing the horizontal slide frame 37, the vertical push rod 11 moves up and down in the horizontal slide frame 37, so that the vertical push rod 11 has two actions: moving back and forth and moving up and down. The vertical push rod 11 drives the rotating seat 39 to move back and forth and move up and down, thereby pushing the seed-throwing disc 14 to rotate. Based on the above and referring to the appendix Figure 10 This allows the seed-throwing tray 14 and the seed positioning cylinder 16 to have three possible working states. State a: Both the seed-throwing disc 14 and the seed positioning cylinder 16 are in a vertical position. Seed sowing is performed in this state. The operation is as follows: The seed-throwing disc 14 rotates in the vertical plane, driving the seed positioning cylinder 16 to rotate via the support base 31. This brings the lower end of the seed positioning cylinder 16 closer to the planting hole. After rotating to a certain angle, the limiting rod 15 pushes upward against the contact part 17, preventing the seed positioning cylinder 16 from falling. However, the seed-throwing disc 14 continues to rotate. The stop rod 33 at the inlet of the seed positioning cylinder 16 pushes upward against the extension part 32 and the arc-shaped baffle 23, thus allowing the seed-throwing disc 14 to continue rotating. The seed-splitting port of 4 is opened to allow the seeds in the seed-splitting tray 14 to fall into the seed positioning cylinder 16, and then be discharged into the acupoint. Afterwards, the seed-splitting tray 14 rotates in the reverse direction, causing the extension 32 and the arc-shaped baffle 23 to cover the seed-splitting port again. The seed-splitting tray 14 drives the seed positioning cylinder 16 to move upward back to its original position, thus completing the seeding process. That is, the seeding process repeats as follows: the seed positioning cylinder 16 moves down to approach the acupoint, the seed-splitting port opens to discharge the seeds, the seeds fall from the seed positioning cylinder 16 into the acupoint, the seed-splitting port closes, and the seed-splitting tray 14 rotates in the reverse direction to drive the seed positioning cylinder 16 to move upward back to its original position. State b: The seed-throwing disc 14 is in a vertical state and the seed positioning cylinder 16 is in a horizontal state. At this time, the seed row sowing is performed. The operation method is as follows: The seed-throwing disc 14 rotates on the vertical plane, but the seed positioning cylinder 16 rotates 90° relative to the seed-throwing disc 14. The seed positioning cylinder 16 drives the support base 31 to rotate, the support base 31 drives the inner rotating column 28 to rotate, and the inner rotating column 28 drives the push rod 27 to rotate. The push rod 27 rotates in the support hole 29 to push the arc-shaped baffle 23 upward, so that the extension 32 of the arc-shaped baffle 23 leaves the lower seed-throwing port. Then the lower seed-throwing port and the upper seed-throwing port are always in the open state. When the seed-throwing disc 14 rotates in a forward and reverse cycle, the seeds are thrown out from the lower seed-throwing port. Since the seed-throwing disc 14 is in a vertical state, the thrown seeds are arranged in a line, that is, row sowing is performed. State c: The seed-splitting disc 14 is in a horizontal state and the seed positioning cylinder 16 is in a vertical state. Seed sowing is carried out in this state. The operation method is as follows: the seed-splitting disc 14 rotates on the horizontal surface, and the seed positioning cylinder 16 still rotates 90° relative to the seed-splitting disc 14. Then the lower seed-splitting port and the upper seed-splitting port are always in the open state. When the seed-splitting disc 14 rotates in both directions, the seeds are simultaneously flung out from the upper seed-splitting port and the lower seed-splitting port. Based on states a, b, and c above, the spacing of a row of seed-throwing discs 14 can also be adjusted. (Refer to the appendix for further details.) Figure 13The adjustment method is as follows: unscrew the nut 21, so that the nut 21 no longer presses against the arc-shaped support frame 5, allowing the rotating frame 6 to be in a free-rotating state. At the same time, the rotating frame 6 can be rotated, and the rotation of the fan-shaped frame 12 and the seed-throwing disc 14 can be controlled by the control component. The seed-throwing disc 14 remains in a vertical state, but the lateral distance between two adjacent seed-throwing discs 14 will change. When the rotating frame 6 is in a horizontal state, the lateral distance between two adjacent seed-throwing discs 14 is the largest. When the rotating frame 6 is in an inclined state, the lateral distance between two adjacent seed-throwing discs 14 becomes smaller.
