Description

Technical Field

[0001] This invention relates to the field of agricultural seeding equipment technology, and in particular to an adjustable precision seeding machine that integrates seeding and water injection. Background Technology

[0002] Legumes are an important food crop grown in dryland areas of both northern and southern China, with a wide planting area and significant economic value. Currently, legumes in most remote areas and rural areas are still sown manually. Manual sowing faces numerous problems. First, it's difficult to accurately control the planting depth and density. Second, it consumes a large amount of manpower and resources; each step of the sowing process—tilling, sowing, and watering—requires significant time and effort. While mechanical sowing can effectively solve some of the problems associated with manual sowing, it still has many shortcomings. Existing seeders on the market are mainly row seeders, but due to their generally large size or high price, they are unsuitable for sowing in small rural plots. Most current hill-planting machines cannot adjust the spacing between hills; even if they can, the entire hill-planting device needs to be replaced, which is costly, time-consuming, and labor-intensive. Furthermore, the design of the hill-planting claws in existing hill-planting machines commonly suffers from soil clogging, delayed opening, or difficulty in opening, resulting in missed sowing and significantly affecting the sowing quality. In addition, manual watering is still required after mechanical sowing, continuing to consume manpower and resources. In summary, existing mechanical seeders still have shortcomings such as low level of intelligence, inability to flexibly change the spacing between holes according to different crop growth needs, non-autonomous opening of the hole-forming claws, and the need for manual irrigation after sowing. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable precision hill-seeding machine that integrates sowing and watering, so as to achieve flexible and stepless adjustment of the plant spacing in the hill.

[0004] This invention is achieved through the following technical solution:

[0005] An adjustable precision hill-seeding machine with integrated sowing and watering includes a double-row hill-seeder. The double-row hill-seeder is attached to the machine via a mounting bracket. A left-right extending main shaft is rotatably mounted on the mounting bracket. The double-row hill-seeder includes two hill-seeding wheel assemblies that are symmetrically mounted on the main shaft. The side of the two hill-seeding wheel assemblies facing each other is the inner side, and the side facing away from each other is the outer side.

[0006] Each seeding reel assembly includes a seed box, a mounting end cap, a seed picker, a seed metering device, and a seed-forming mechanism. The seed picker is rotatably mounted on the main shaft. The mounting end cap is fixed to the outside of the seed picker, and the seed box is fixed to the outside of the mounting end cap. The seed picker has a seed chamber inside, and a notch at the bottom serves as a seed outlet. The seed box sidewall and the mounting end cap each have an inwardly sloping, interconnected guide channel, which connects the inner cavity of the seed box to the seed chamber. The seed metering device includes a seed metering wheel body located around the seed picker. The inner side of the seed metering wheel body is fixedly mounted on the main shaft via the seed metering end cap. Multiple seed guide tubes are evenly distributed circumferentially on the outer circumferential surface of the seed metering wheel body. Each seed guide tube extends radially outward along the seed metering wheel body. Multiple seed guide tubes are evenly distributed circumferentially on the inner circumferential surface of the seed metering wheel body. The inoculation box is used to receive seeds falling from the seed outlet of the seed dispenser. Multiple inoculation boxes are connected to multiple seed guide tubes in a one-to-one correspondence. The hole-forming mechanism includes multiple hole-forming components. Each hole-forming component includes an arc-shaped extrusion plate and telescopic tubes and hole-forming claws fixed on both sides of the extrusion plate. The extrusion plates of the multiple hole-forming components together form an extrusion ring. The telescopic tubes of the multiple hole-forming components are slidably fitted onto multiple seed guide tubes of the seed metering wheel in a one-to-one correspondence. The main shaft is also equipped with two plant spacing adjusters corresponding to the two hole-seeding wheel components. By driving the telescopic tubes of the corresponding multiple hole-forming components to slide along their respective seed guide tubes through the plant spacing adjusters, the circumferential spacing of the hole-forming claws of the multiple hole-forming components can be adjusted, thereby adjusting the sowing plant spacing.

[0007] As a preferred embodiment of the aforementioned hill-planting machine, the plant spacing adjuster includes an adjusting ring slidably mounted on the main shaft. Multiple connecting rods are hinged circumferentially on the adjusting ring. An adjusting positioning connecting rod is fixed on the telescopic tube of the multiple hill-forming components of each hill-forming mechanism. The adjusting positioning connecting rod extends along the axis of the main shaft. The other ends of the multiple connecting rods on the adjusting ring are hinged one-to-one with the inner ends of the multiple adjusting positioning connecting rods of the corresponding hill-forming mechanism. The adjusting ring is driven to move axially along the main shaft by the plant spacing adjustment drive mechanism, thereby causing the multiple telescopic tubes of the corresponding hill-forming mechanism to slide along their respective seed guide tubes.

[0008] As a preferred embodiment of the above-mentioned hill-planting machine, the plant spacing adjustment drive mechanism is a push-pull electric cylinder.

[0009] As a preferred embodiment of the aforementioned seeding machine, in the seeding assembly, the seeding claw is formed by the engagement of a fixed claw and a movable claw to create a complete inverted conical shell, with the pointed end of the seeding claw facing downwards. The upper end of the fixed claw is fixed to the extrusion plate, and the upper end of the movable claw is hinged to the upper end of the fixed claw via a hinge sleeve and a torsion spring. A lever is fixed to the hinge sleeve at the upper end of the movable claw, and the outer section of the lever is bent into a Z-shape. In its natural state, under the action of the torsion spring, the movable claw and the fixed claw are in contact, causing the seeding claw to be in a closed state. When the outer end of the lever is squeezed by an external force, it will drive the movable claw to rotate away from the fixed claw, causing the seeding claw to open.

[0010] As a preferred embodiment of the aforementioned seeding machine, the outer side of the mounting end cover is provided with a vertically extending slide groove, in which a self-opening adjuster is slidably arranged. The self-opening adjuster includes a mounting base, a slide rail fixed to the top of the mounting base, an adjustment track fixed to one side of the mounting base, and a pressing block fixed to the bottom of the mounting base. The slide rail extends vertically and slides in cooperation with the slide groove. The adjustment track is located below the mounting end cover, and an arc-shaped groove concentric with the main shaft is opened on the inner side of the adjustment track. The outer end of the adjustment positioning link on the telescopic tube is an embedded end. The embedded end of the adjustment positioning link of the lower seeding component in the seeding mechanism is embedded in the arc-shaped groove of the adjustment track and can slide in the arc-shaped groove. As the seeding wheel rotates, it drives the multiple seeding components of the seeding mechanism to rotate together. When the seeding component rotates to the lower position, the pressing block presses the outer end of the lever of the seeding claw, causing the seeding claw to open.

[0011] As a preferred embodiment of the aforementioned seeder, each seeding reel assembly also includes a synchronous precision watering system. The synchronous precision watering system includes a rigid watering pipe, a water pipe mounting block fixed to the outside of the seed box, and a guide channel extending forward and backward on the water pipe mounting block. The rigid watering pipe is slidably installed in the guide channel of the water pipe mounting block. The inlet end of the rigid watering pipe is connected to a water pump through a flexible water pipe, and the outlet end of the rigid watering pipe is connected to a water outlet bend through a solenoid valve. After the water outlet bends downward, it is connected to a water outlet head. The rigid watering pipe is driven to move forward and backward in the guide channel of the water pipe mounting block through a water pipe drive mechanism to adjust the forward and backward position of the water outlet head.

[0012] As a preferred embodiment of the aforementioned seeder, the synchronous precision watering system further includes a watering detection, leveling, and positioning mechanism. The watering detection, leveling, and positioning mechanism includes a positioning plate, an L-shaped balance bar, and a positioning pulley assembly. The positioning plate is mounted on the machine and has a positioning groove extending in the front-to-back direction. The positioning pulley assembly includes a positioning cylinder and positioning pulleys fixed at the upper and lower ends of the positioning cylinder. The positioning cylinder slides in conjunction with the positioning groove of the positioning plate and can only slide back and forth along the positioning groove. The two positioning pulleys are located on the upper and lower sides of the positioning plate, respectively. The horizontal bar of the L-shaped balance bar extends in the front-to-back direction and its rear end is fixed to the outside of the seed box. The vertical bar of the L-shaped balance bar is located at the front end of the horizontal bar and slides upward through the inner hole of the positioning cylinder.

[0013] As a preferred embodiment of the aforementioned seeding machine, the mounting frame includes a mounting beam and a mounting frame body. The mounting beam extends horizontally and is rotatably mounted on the machine. The main shaft is connected to the lower rear of the mounting beam via the mounting frame body. The mounting frame body is provided with horizontally extending crossbars, and a lifting electric cylinder is provided below the crossbars. The cylinder body of the lifting electric cylinder is hinged to the machine, and the piston rod of the lifting electric cylinder is hinged to the crossbars. By extending and retracting the piston rod of the lifting electric cylinder, the mounting frame is driven to rotate around the axis of the mounting beam, thereby driving the main shaft and the double-row seeders mounted on the main shaft to rotate together.

[0014] As a preferred solution of the above-mentioned hill-drop planter, the synchronous precision water injection system further includes a precision water injection detection device. The precision water injection detection device includes a Hall element and a plurality of electromagnetic sheets. The Hall element is fixed inside the bottom of the mounting end cover. The plurality of electromagnetic sheets are installed at the edge outside the seed metering wheel body and are evenly distributed along the circumferential direction of the seed metering wheel body. The plurality of electromagnetic sheets correspond to the plurality of seed guide tubes on the seed metering wheel body one by one. When the electromagnetic sheet rotates to the directly below with the seed metering wheel body, it is opposite to the induction end of the Hall element.

[0015] As a preferred solution of the above-mentioned hill-drop planter, the seed picker includes a seed picker wheel rotatably sleeved on the main shaft. The seed chamber is arranged inside the seed picker wheel. The bottom of the seed chamber is open and a seed discharging ring is rotatably installed. A plurality of seed picking holes are evenly distributed along the circumferential direction on the outer circumferential surface of the seed discharging ring. The seed picking holes are used to receive the seeds in the seed chamber. As the seed discharging ring rotates, the seeds are taken out of the seed chamber and fall through the seed picking outlet below; There is also a brush obliquely above the seed discharging ring. The brush is rotatably installed in the seed chamber and rotates in the same direction as the seed discharging ring. The bristles of the brush contact the outer circumferential surface of the seed discharging ring.

[0016] The present invention has the following advantages compared with the prior art:

[0017] 1. The sowing and water injection integrated adjustable precision hill-drop planter provided by the present invention adopts a set of plant spacing adjuster composed of an adjusting ring and a connecting rod mechanism designed independently, which can realize the stepless adjustment of the in-hole plant spacing. That is, the in-hole plant spacing between two adjacent in-hole claws of the hill-drop wheel assembly can be adjusted to any parameter within the adjustable range according to the crop planting requirements, greatly improving the sowing application range of the machine. Most of the existing hill-drop planters have a fixed plant spacing or a very complex step for changing the plant spacing. The hill-drop planter designed by the present invention with stepless adjustment of plant spacing fills the blank in this field on the market.

[0018] 2. The sowing and water injection integrated adjustable precision hill-drop planter provided by the present invention designs a set of self-opening adjuster that联动调节随株距变化. It ensures that the self-opening function of the in-hole claw can still proceed normally after the plant spacing adjustment and continues to complete the in-hole sowing. The design of the above self-opening adjuster realizes the联动调节 of the self-opening of the in-hole claw with the plant spacing adjustment.

[0019] 3. The sowing and water injection integrated adjustable precision hill-drop planter provided by the present invention designs a set of telescopic adjustable synchronous precision water injection system that联动调节随株距变化. It can meet the requirements of multi-crop planting modes and ensure that there is no missed sowing phenomenon, and no manual irrigation is required later; while improving the sowing quality and efficiency of crops, it can also save a large amount of manpower and material resources. The联动式 synchronous precision water injection system can realize the accurate hole positioning, precision water injection of the water injection system and the联动定位 with the plant spacing adjustment through the designed water injection detection leveling and positioning mechanism and precision water injection detection device. Specifically, it is embodied as:

[0020] Precise acupoint location: To enable the acupoint planter to accurately locate and inject water after the acupoints are formed, the Hall element and electromagnetic plate in the precision water injection detection device are properly placed, and the water injection detection leveling and positioning mechanism ensures that the detection element, i.e. the Hall element, is fixed at the bottom of the installation end cover and remains in a constant position, so that the water injection point always coincides with the formed acupoint, thus achieving precise acupoint location.

[0021] Precision water injection: The controller controls the opening time of the solenoid valve to achieve precise control of the water injection volume in a single operation, or the water pump can be adjusted to achieve precise water injection in a single operation.

[0022] Linkage positioning with plant spacing adjustment: The controller controls the plant spacing adjuster and the side electric cylinder of the watering system to achieve the change of hole spacing. At the same time, the side electric cylinder drives the rigid watering pipe to synchronously control the change of water outlet position, so that the hole and the watering point always coincide. In this way, the linkage adjustment of the telescopic adjustable watering system with the change of plant spacing adjuster is completed. Attached Figure Description

[0046] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0047] See Figures 1 to 22 This embodiment discloses an adjustable precision seeder with integrated sowing and watering, including a double-row seeder. The double-row seeder is attached to the implement via a mounting frame 1. In this embodiment, the implement is a tracked vehicle 2, and the double-row seeder is attached to the rear of the tracked vehicle 2. A left-right extending main shaft 3 is rotatably mounted on the mounting frame 1. The double-row seeder includes two seeder wheel assemblies 4 symmetrically mounted on the main shaft 3. The side of the two seeder wheel assemblies 4 facing each other is the inner side, and the side facing away from each other is the outer side.

[0048] The mounting frame 1 includes a mounting beam 5 and a mounting frame body 6. The mounting beam 5 extends left and right and is rotatably mounted on the machine via two left and right beam bearing seats 7. The main shaft 3 is connected to the lower rear of the mounting beam 5 via the mounting frame body 6. The bottom of the mounting frame body 6 is provided with two left and right mounting base plates 8, and the main shaft bearing seats 9 are fixed on the two mounting base plates 8 respectively. The main shaft 3 is rotatably mounted on the two main shaft bearing seats 9. The mounting frame body 6 is provided with a left and right extending crossbar 10. Below the crossbar 10 is a lifting electric cylinder 11. The cylinder body of the lifting electric cylinder 11 is hinged to the machine. The piston rod of the lifting electric cylinder 11 is hinged to the crossbar 10. By extending and retracting the piston rod of the lifting electric cylinder 11, the mounting frame 1 is driven to rotate around the axis of the mounting beam 5, thereby driving the main shaft 3 and the double-row seeder mounted on the main shaft 3 to rotate together.

[0049] When the piston rod of the lifting electric cylinder 11 extends or retracts, it pushes upward or pulls downward on the main body 6 of the mounting bracket, causing the main body 6 of the mounting bracket to rotate relative to the beam bearing seat 7 via the mounting beam 5 fixed at the upper end. That is, the lifting electric cylinder 11 drives the main body 6 of the mounting bracket to rotate along the axis of the mounting beam 5, thereby lifting or lowering the main shaft 3, and in turn driving the double-row seeders installed on the main shaft 3 to be lifted or lowered together.

[0050] Each seeding reel assembly 4 includes a seed box 12, a mounting end cap 13, a seed extractor 14, a seed metering device 15, and a seed-forming mechanism 16. The seed extractor 14 is rotatably mounted on the main shaft 3. The mounting end cap 13 is fixed to the outside of the seed extractor 14, and the seed box 12 is fixed to the outside of the mounting end cap 13. The seed extractor 14 has a seed chamber 17 inside, and a notch at the bottom of the seed extractor 14 serves as a seed extraction outlet 18. The side wall of the seed box 12 and the mounting end cap 13 have inwardly downward inclined openings. A slanted and interconnected guide channel 19 connects the inner cavity of the seed box 12 with the seed chamber 17. The seed metering device 15 includes a seed metering wheel body 20 located around the seed taker 14. The inner side of the seed metering wheel body 20 is fixedly mounted on the main shaft 3 by a seed metering end cap 21. Multiple seed guide tubes 22 are evenly distributed circumferentially on the outer circumferential surface of the seed metering wheel body 20. Each seed guide tube 22 extends radially outward along the seed metering wheel body 20. Multiple seed guide tubes 22 are evenly distributed circumferentially on the inner circumferential surface of the seed metering wheel body 20. The device is equipped with multiple inoculation boxes 23, which are used to receive seeds falling from the seed outlet 18 of the seed dispenser 14. The multiple inoculation boxes 23 are connected to multiple seed guide tubes 22 in a one-to-one correspondence. The hole-forming mechanism 16 includes multiple hole-forming components 24. Each hole-forming component 24 includes an arc-shaped extrusion plate 25 and telescopic tubes 26 and hole-forming claws 27 fixed on both sides of the extrusion plate 25. The extrusion plates 25 of the multiple hole-forming components 24 together form an extrusion ring. The telescopic tubes 26 of the multiple hole-forming components 24 are slidably fitted onto the multiple seed guide tubes 22 of the seed metering wheel body 20 in a one-to-one correspondence. The main shaft 3 is also equipped with two plant spacing adjusters 28 corresponding to the two hole-seeding wheel components 4 respectively. By driving the telescopic tubes 26 of the corresponding multiple hole-forming components 24 to slide along their respective seed guide tubes 22 through the plant spacing adjusters 28, the circumferential spacing of the hole-forming claws 27 of the multiple hole-forming components 24 can be adjusted, thereby adjusting the sowing plant spacing.

[0051] The seed extractor 14 includes a seed extractor wheel 29 rotatably mounted on the main shaft 3. A seed chamber 17 is located inside the seed extractor wheel 29. The bottom of the seed chamber 17 is open and a seed dispensing ring 30 is rotatably mounted thereon. Multiple seed extractor holes 31 are evenly distributed circumferentially on the outer circumferential surface of the seed dispensing ring 30. The distribution of the multiple seed extractor holes 31 on the seed dispensing ring 30 can be configured as follows: multiple seed extractor holes 31 are arranged in several rows along the circumferential direction of the seed dispensing ring 30. Each row of seed extractor holes 31 includes two seed extractor holes 31 arranged axially along the seed dispensing ring 30. The seed extractor holes 31 are used to collect the seeds in the seed chamber 17. As the seed dispensing ring 30 rotates, the seeds are carried out of the seed chamber 17 and fall through the seed extraction outlet 18 below. A brush 32 is also provided diagonally above the seed dispensing ring 30. The brush 32 is rotatably mounted inside the seed chamber 17 and rotates in the same direction as the seed dispensing ring 30. The bristles of the brush 32 are in contact with the outer circumferential surface of the seed dispensing ring 30. The function of the brush 32 is to brush away excess seeds on the seed metering ring 30 and leave them in the seed chamber 17, ensuring that only the seeds in the two seed holes 31 of a single row on the seed metering ring 30 are carried out of the seed chamber 17 and fall into the seed outlet 18 below, and then fall into the corresponding inoculation box 23 through the seed outlet 18, so as to achieve precise seed collection.

[0052] Each seeding reel assembly 4 also includes a seeding transmission system, which includes a main shaft gear 33, a transmission gear 34, a seed metering ring gear 35, a reversing gear 36, and a brush gear 37. The main shaft gear 33 is fixedly mounted on the main shaft 3. The transmission gear 34, the seed metering ring gear 35, and the seed metering ring 30 are coaxially fixedly mounted. The brush gear 37 and the brush 32 are coaxially fixedly mounted. The reversing gear 36 is rotatably mounted on the seed-collecting wheel 29, and the transmission gear 34 meshes with the main shaft gear 33. The seed metering ring gear 35 and the brush gear 37 are connected by the reversing gear 36. As the main shaft 3 rotates, the main shaft 3 drives the main shaft gear 33 to rotate, which in turn drives the transmission gear 34 to rotate, thereby driving the seed metering ring gear 35 and the seed metering ring 30 to rotate. The rotation of the seed metering ring gear 35 then drives the brush gear 37 to rotate in the same direction through the reversing gear 36, thereby driving the brush 32 and the seed metering ring 30 to rotate in the same direction.

[0053] The working process of seed box 12, seed dispenser 14 and seed metering device 15 is as follows:

[0054] Seeds fall from the seed box 12 into the seed chamber 17 of the seed-collecting wheel 29 via the inclined guide channel 19. When the main shaft 3 rotates, it drives the main shaft gear 33, which is fixedly connected to the main shaft 3, to rotate. The main shaft gear 33, through the transmission of the sowing transmission system, drives the seed metering ring 30 and the brush 32 to rotate in the same direction. The rotation direction of the brush 32 is the same as that of the seed metering ring 30. This leaves excess seeds in the seed chamber 17, ensuring that only the seeds in the two seed-collecting holes 31 of a single row on the seed metering ring 30 are carried out and fall into the corresponding inoculation box 23 below, achieving precision seed collection. When the seed metering wheel 20 rotates, the seeds are guided out from their corresponding seed guide tube 22 and enter the seed-forming claw 27, ensuring precision sowing.

[0055] The plant spacing adjuster 28 includes an adjusting ring 38 that is slidably mounted on the main shaft 3. Multiple connecting rods 39 are hinged circumferentially on the adjusting ring 38. An adjusting positioning connecting rod 40 is fixed on the telescopic tube 26 of the multiple hole-forming components 24 of each hole-forming mechanism 16. The adjusting positioning connecting rod 40 extends along the axis of the main shaft 3. The other end of the multiple connecting rods 39 on the adjusting ring 38 is hinged to the inner end of the multiple adjusting positioning connecting rods 40 of the corresponding hole-forming mechanism 16. The adjusting ring 38 is driven to move axially along the main shaft 3 by the plant spacing adjustment drive mechanism, thereby driving the multiple telescopic tubes 26 of the corresponding hole-forming mechanism 16 to slide along their respective seed guide tubes 22. The plant spacing adjustment drive mechanism adopts a push-pull electric cylinder 41. The cylinder body of the push-pull electric cylinder 41 is installed in the mounting box 42, which is fixed on the main shaft 3. The piston rod of the push-pull electric cylinder 41 is fixedly connected to the adjusting ring 38. By extending and retracting the piston rod of the push-pull electric cylinder 41, the adjusting ring 38 is driven to move axially along the main shaft 3. Multiple connecting rods 39 pull multiple adjusting and positioning connecting rods 40, causing multiple telescopic tubes 26 to slide along their respective seed guide tubes 22, thereby driving multiple hole-forming claws 27 to move axially along each seed guide tube 22, realizing the change of the circumferential distance between adjacent hole-forming claws 27. That is, the plant spacing of the seeder can be adjusted within the adjustable range according to the crop requirements, thus realizing stepless adjustment of the plant spacing.

[0056] In the cavity forming component 24, the cavity forming claw 27 is formed by the engagement of a fixed claw 43 and a movable claw 44 to form a complete inverted conical shell, with the pointed end of the cavity forming claw 27 facing downwards. The upper end of the fixed claw 43 is fixed to the extrusion plate 25, and the upper end of the movable claw 44 is hinged to the upper end of the fixed claw 43 through a hinge sleeve 45 and a torsion spring. A lever 46 is fixed on the hinge sleeve 45 at the upper end of the movable claw 44. The outer section of the lever 46 is bent into a Z-shape. In its natural state, under the action of the torsion spring, the movable claw 44 and the fixed claw 43 are in contact, so that the cavity forming claw 27 is in a closed state. When the outer end of the lever 46 is squeezed by an external force, it will drive the movable claw 44 to rotate away from the fixed claw 43, so that the cavity forming claw 27 opens.

[0057] The outer side of the mounting end cap 13 is provided with a vertically extending slide groove 47. A self-opening adjuster 48 is slidably disposed in the slide groove 47. The self-opening adjuster 48 includes a mounting base 49, a slide rail 50 fixed to the top of the mounting base 49, an adjustment track 51 fixed to one side of the mounting base 49, and a pressing block 52 fixed to the bottom of the mounting base 49. The slide rail 50 extends vertically and slides in cooperation with the slide groove 47. The inner side of the adjustment track 51 has an arc-shaped groove 53 concentric with the main shaft 3. The outer end of the adjustment and positioning connecting rod 40 on the telescopic tube 26 is an embedded end 54. The adjustment and positioning of the cavity forming component 24 located below in the cavity forming mechanism 16. The insert end 54 of the connecting rod 40 is inserted into the arc-shaped groove 53 of the adjusting track 51 and can slide in the arc-shaped groove 53. One end of the arc-shaped groove 53 along the circumferential direction is the inlet end, and the inlet end of the arc-shaped groove 53 is a flared flared mouth, so that the insert end 54 of the next adjusting positioning connecting rod 40 can smoothly enter the arc-shaped groove 53 from the inlet end of the arc-shaped groove 53. As the seeding wheel 20 rotates, it drives the multiple hole-forming components 24 of the hole-forming mechanism 16 to rotate together. When the hole-forming component 24 rotates to the bottom, the pressing block 52 presses the outer end of the lever 46 of the hole-forming claw 27, so that the hole-forming claw 27 opens. During the rotation of the hole-forming mechanism 16, it is ensured that the insert end 54 of the adjusting positioning connecting rod 40 of at least one hole-forming component 24 is always in the arc-shaped groove 53 of the adjusting track 51 to prevent the self-opening regulator 48 from falling off and failing to play its role in self-opening the hole-forming claw 27.

[0058] The working process of the cavitation mechanism 16 is as follows:

[0059] As the entire seeding wheel assembly 4 rotates forward, multiple seed-forming claws 27 on the seed metering wheel 20 alternately form holes. Seeds move from the seed picker 14 to the seed metering device 15, and then from the seed guide tube 22 into the seed-forming claws 27. During this process, at least one of the adjusting and positioning linkages 40 of the seed-forming assembly 24 always moves in the arc-shaped groove 53 of the self-opening regulator 48. When the seed-forming claw 27 moves to an appropriate position below the seed picker 14, the lever 46 on the seed-forming claw 27 begins to contact the squeezing block 52. The squeezing block 52 squeezes the lever 46 to rotate, which in turn drives the fixed movable claw 44 on it to rotate relative to the fixed claw 43, opening the seed-forming claw 27. At this time, the seeds in the seed-forming claw 27 fall into the formed holes, completing the sowing. When the lever 46 separates from the squeezing block 52, the seed-forming claw 27 automatically closes under the action of the torsion spring, preparing for the next sowing. When adjusting the plant spacing of the seeding wheel assembly 4, the adjusting positioning link 40 drives the seeding claw 27 to extend and retract along the seed guide tube 22 axially via the telescopic tube 26 fixed to it, ensuring that at least one of the seeding components 24 has its embedded end 54 of the adjusting positioning link 40 embedded in the arc groove 53 of the adjusting track 51. This drives the slide rail 50 of the self-opening regulator 48 to move up and down along the slide groove 47, thereby driving the squeezing block 52 to move up and down. This makes the height position of the squeezing block 52 linked with the plant spacing adjustment of the seeding claw 27, ensuring that the seeding claw 27 can open smoothly when sowing under different plant spacing conditions.

[0060] Each seeding reel assembly 4 also includes a synchronous precision watering system, which includes a rigid watering pipe 55. A water pipe mounting block 56 is fixed to the outside of the seed box 12. The water pipe mounting block 56 has a guide channel extending forward and backward. The rigid watering pipe 55 is slidably installed in the guide channel of the water pipe mounting block 56. The inlet end of the rigid watering pipe 55 is connected to the water pump 58 through a flexible water pipe 57. The water pump 58 is a booster pump. A bracket 59 is installed on the body of the tracked vehicle 2. A water tank 60 is installed on the bracket 59. The two seeding reel assemblies 4 can share a water tank 60. The bottom of the water tank 60 is connected to the inlet of the water pump 58 through a straight pipe connector. The outlet of the water pump 58 is connected to the corresponding flexible water pipe 57 through two straight pipe connectors. The outlet end of the rigid water injection pipe 55 is connected to a water outlet bend 62 via a solenoid valve 61. The water outlet bend 62 downwards and connects to a water outlet head 63. A water pipe drive mechanism drives the rigid water injection pipe 55 to move back and forth in the guide channel of the water pipe mounting block 56, thereby adjusting the position of the water outlet head 63. The water pipe drive mechanism can be a side electric cylinder 64, which is installed on the outside of the seed box 12. The piston rod of the side electric cylinder 64 is connected to a fastening sleeve 65, which is fixed to the rigid water injection pipe 55. By extending or retracting the piston rod of the side electric cylinder 64, the rigid water injection pipe 55 is moved back and forth in the guide channel of the water pipe mounting block 56.

[0061] The working process of the synchronous precision water injection system is as follows:

[0062] Water flows through water tank 60, is pressurized by water pump 58, and then passes through foldable flexible water pipe 57 and rigid water injection pipe 55 to reach solenoid valve 61. Solenoid valve 61 opens upon receiving a command from the controller, and water flows through solenoid valve 61 and into the prepared holes via the outlet head 63 of outlet bend 62. To ensure that the water injection position remains correct even when the hole spacing changes, the rigid water injection pipe 55 must drive the extension and retraction of solenoid valve 61 and outlet bend 62 in conjunction with the hole-forming claw 27, establishing a functional relationship of mutual linkage. When the plant spacing adjuster 28, controlled by the controller, pushes and pulls the electric cylinder 41 to move the adjusting ring 38 axially to change the plant spacing, the side electric cylinder 64 is simultaneously controlled by the controller. This simultaneously controls the side electric cylinder 64 outside the seed box 12 to adjust the rigid water injection pipe 55 according to the relationship with the plant spacing adjustment, ensuring the relative position of the water outlet head 63 of the water injection system with the hole to be watered, thereby achieving stepless adjustment of the plant spacing and linkage adjustment of the water injection system.

[0063] The synchronous precision water injection system also includes a water injection detection, leveling, and positioning mechanism. The water injection detection, leveling, and positioning mechanism includes a positioning plate 66, an L-shaped balance bar 67, and a positioning pulley group 68. The positioning plate 66 is mounted on the machine and has a positioning groove 69 extending in the front-to-back direction. The positioning pulley group 68 includes a positioning cylinder and positioning pulleys fixed at the upper and lower ends of the positioning cylinder. The positioning cylinder slides in cooperation with the positioning groove 69 of the positioning plate 66 and can only slide back and forth along the positioning groove 69. The two positioning pulleys are located on the upper and lower sides of the positioning plate 66, respectively. The horizontal bar of the L-shaped balance bar 67 extends in the front-to-back direction and its rear end is fixed to the outside of the seed box 12. The vertical bar of the L-shaped balance bar 67 is located at the front end of the horizontal bar and slides upward through the inner hole of the positioning cylinder.

[0064] The synchronous precision water injection system also includes a precision water injection detection device, which includes a Hall element 70 and multiple electromagnetic plates 71. The Hall element 70 is fixed to the bottom inner side of the mounting end cover 13. The multiple electromagnetic plates 71 are installed on the outer edge of the seed metering wheel body 20 and are evenly distributed around the circumference of the seed metering wheel body 20. The multiple electromagnetic plates 71 correspond one-to-one with the multiple seed guide tubes 22 on the seed metering wheel body 20. When the electromagnetic plates 71 rotate to the bottom with the seed metering wheel body 20, they are opposite to the sensing end of the Hall element 70.

[0065] The working process of the precision water injection detection device is as follows:

[0066] As the seeding wheel assembly 4 rotates forward, when the seeding claw 27 forms a seed at the lowest point, the Hall element 70 aligns with the corresponding electromagnetic plate 71 at the lowest point of the seed metering wheel 20. The Hall element 70 detects the corresponding electromagnetic plate 71 and transmits a signal to the controller terminal. The controller then controls the opening time of the solenoid valve 61. During the opening time of the solenoid valve 61, water flows precisely into the previously formed seed holes through the outlet bend 62. After the controller's set time, the solenoid valve 61 automatically closes, thus completing one cycle of seeding, one opening and closing of the solenoid valve 61, and one water injection. The seeding wheel assembly 4 continues to rotate, and when the Hall element 70 detects the next electromagnetic plate 71, the solenoid valve 61 opens again. This cycle repeats continuously, completing the continuous seeding, sowing, and water injection. Precise water injection can be achieved by setting the opening time of the solenoid valve 61 to the controller, or by changing the model of the water pump 58 to a higher-powered pump to increase the flow rate and thus the water injection volume. These two methods can be used to achieve precise water injection.

[0067] The working process of the water injection detection, leveling, and positioning mechanism is as follows:

[0068] During the rotation of the seeding wheel assembly 4 and the lifting or lowering of the double-row seeders with the hanging frame 1, the horizontal guiding action of the positioning groove 69 on the positioning plate 66 and the vertical guiding action of the positioning pulley group 68 ensure that the horizontal bar of the L-shaped balance bar 67 remains horizontal and the vertical bar remains vertical. Since the seed box 12 is fixed to the horizontal bar of the L-shaped balance bar 67, it ensures that the seed box 12 remains vertical and will not flip over. This has the following functions:

[0069] First, the mounting end cap 13 and the seed extractor 14, which are fixed to the seed box 12, are always kept in a vertical position to ensure the smooth progress of the seed extraction operation.

[0070] Secondly, the rigid water injection pipe 55 and solenoid valve 61 fixedly installed on the seed box 12 always remain horizontal, thereby ensuring that the water injection position of the water outlet bend 62 remains unchanged and ensuring the precise water injection position.

[0071] Furthermore, since the Hall element 70 of the precision water injection detection device is fixed on the mounting end cover 13, the Hall element 70 can remain in a fixed position, thus ensuring that the position of the precision water injection detection remains unchanged.

[0072] The working process of the adjustable precision seeder with integrated sowing and watering provided in this embodiment is as follows:

[0073] First, according to crop planting requirements, the controller controls the extension and retraction of the push-pull electric cylinder 41, which drives the plant spacing adjuster 28 to infinitely adjust the hole-forming distance of the seeding wheel assembly 4, ensuring that the hole spacing meets crop growth requirements. Simultaneously, the plant spacing adjuster 28, through the adjustment positioning linkage 40 embedded in the arc-shaped groove 53 of the adjustment track 51 of the self-opening adjuster 48, moves the self-opening adjuster 48 vertically along the slide 47, thereby moving the extrusion block 52 directly below the self-opening adjuster 48. This achieves linkage adjustment between the height of the extrusion block 52 and the hole-forming distance of the hole-forming claw 27, realizing the linkage between the self-opening adjuster 48 and the plant spacing adjustment. While the plant spacing adjuster 28 is working, the controller also synchronously controls the side electric cylinders 64 on both sides of the seeder, moving the rigid water injection pipe 55 back and forth to the appropriate position, ensuring that the subsequent water injection points always coincide with the holes requiring watering. This achieves linkage adjustment between the synchronous precision water injection system and the plant spacing adjuster 28, and the water injection volume is controlled by settings in the controller.

[0074] During machine operation, the controller uses the lifting electric cylinder 11 to place the seeder in the tilled field. At this time, the piston rod of the lifting electric cylinder 11 retracts, and the mounting bracket 1 is in the lowered state, so that the two seeding wheel assemblies 4 are in contact with the ground. The tracked vehicle 2 is controlled to move forward, and the double-row seeder is attached to the rear of the tracked vehicle 2. Under the traction of the tracked vehicle 2 and the friction between the seeding part and the ground, the seed metering device 15 and the seeding mechanism 16 rotate on their own. The seed metering wheel body 20 drives the main shaft 3 to rotate synchronously. Through the seeding transmission system, the seed metering ring 30 and the brush 32 rotate in the same direction. The movement of the brush 32 and the seed metering ring 30 can achieve precise seed picking. The seeds in the seed box 12 fall into the seed chamber 17. During the rotation of the seed metering ring 30, under the joint action of the brush 32, the seeds in the seed chamber 17 fall into the seed picking hole 31 of the seed metering ring 30 and are carried out of the seed chamber 17, falling into the corresponding inoculation box 23, and then guided into the corresponding seeding claw 27 through the seed guide tube 22. As the seed metering wheel 20 rotates, the embedded end 54 of the lower adjusting positioning linkage 40 rotates in the arc groove 53 of the adjusting track 51 of the self-opening regulator 48. When the hole-forming claw 27 moves directly below the seed taker 14, the lever 46 of the hole-forming claw 27 begins to contact the squeezing block 52. The squeezing block 52 exerts a backward force on the lever 46, causing the hole-forming claw 27 to open. At this time, the seed falls into the prepared hole, completing the sowing. When the lever 46 of the hole-forming claw 27 separates from the squeezing block 52, the hole-forming claw 27 automatically closes under the action of the torsion spring, preparing for the next sowing. While the seeder is working, as it rotates forward, the water injection detection and leveling positioning mechanism keeps the seed box 12 vertical, thus ensuring that the rigid water injection pipe 55 fixedly installed on the seed box 12 and the solenoid valve 61 fixed at its outlet port remain horizontal. This guarantees that the water injection position of the outlet bend 62 remains constant, ensuring precise water injection. Simultaneously, because the detection element of the precision water injection detection device, namely the Hall element 70, is fixed inside the bottom end of the mounting end cover 13, the detection element remains in a constant position, achieving a constant precision water injection detection position. When the hole-forming claw 27 forms a hole at the lowest end, the Hall element... When component 70 rotates to the lowest point of the seeding wheel 20, the electromagnetic plate 71 is aligned with the corresponding electromagnetic plate 71. The corresponding electromagnetic plate 71 is detected, and a signal is transmitted to the controller. The controller then controls the solenoid valve 61 to open. Water flows precisely into the prepared holes through the solenoid valve 61 and the outlet bend 62 within the opening time of the solenoid valve 61. After the controller's set time, the solenoid valve 61 automatically closes, completing one round of precise hole-filling. This achieves simultaneous hole-filling and water injection into the prepared holes while the seeder forms the holes. The tracked vehicle 2 continues to move forward, completing the continuous process of precise hole-filling, precise seeding, and simultaneous water injection. After the tracked vehicle 2 finishes its work, the double-row seeder is first lifted to a safe position using the lifting electric cylinder 11. Then, the hole-filling claws 27 around the seeder are retracted by the plant spacing adjuster 28, causing the double-row seeder to lift off the ground. Finally, the tracked vehicle 2 is controlled to drive out of the cultivated field.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
