Description

Technical Field

[0001] This invention belongs to the field of seeding equipment technology, and in particular relates to a seeding device for various complex terrains. Background Technology

[0002] When sowing seeds in the ground, a plow is typically used to dig a furrow for planting, and then the seeds are sown into it. In existing methods, a crossbeam is installed at the end of a drive unit, and multiple plow blades are mounted on the crossbeam. During operation, the drive unit can move multiple plow blades simultaneously via the crossbeam, thus creating multiple furrows at once and improving efficiency. However, this structure has drawbacks in practical use: when any plow blade encounters a hard obstacle such as a rock, the crossbeam needs to be raised to allow the plow blade to avoid it. However, raising the crossbeam simultaneously raises all the plow blades attached to it, causing the remaining plow blades, which are not encountering obstacles, to also rise, affecting their normal operation. Furthermore, in low-lying, flat areas, the plow blades attached to the crossbeam cannot actively sink to the ground, resulting in unproductive plowing. On undulating slopes, they cannot actively rise, causing the plow blades to sink too deeply into the soil, resulting in uneven furrow depths and affecting subsequent seed germination.

[0003] To optimize vegetation structure, seeders are typically used in desertification restoration operations to mix multiple seed varieties and sow them into the furrows. While this method allows for successful sowing of the mixed seeds, it has significant limitations. When different varieties need to be sown in different areas, the pre-mixed seeds cannot be adjusted to suit the specific needs of each region, making it difficult to adapt to varying sowing requirements. Furthermore, differences in seed size and shape can cause stratification during operation, leading to deviations in the actual seed ratio from the preset proportions. This can result in situations where one type of seed is displaced excessively at certain times, while another is displaced excessively. Summary of the Invention

[0004] (a) Technical problems to be solved This invention provides a seeding device for various types of complex terrain to solve the following problems: 1. When the existing seeding equipment is digging furrows, if any plow blade on the crossbeam encounters an obstacle and needs to avoid it, the crossbeam will lift simultaneously with all the plow blades on it, causing the plow blades that have not encountered obstacles to also lift, thus affecting the normal operation of the plow blades that have not encountered obstacles. 2. The position of the plow blade cannot be adjusted according to the undulating ground, resulting in uneven depths of the furrows. 3. Existing seeders have a single sowing method and cannot adjust the seed variety combination according to the specific needs of different regions during sowing.

The free ends of the two second connecting arms are rotatably connected to the two sides of the card seat respectively.

[0015] (III) Beneficial Effects Compared with the prior art, the beneficial effects of the present invention are as follows: I. In this invention, while the first hook spring tightens the plowshare holder, it does not completely lock the plowshare holder. During the digging process, if a hard obstacle such as a stone blocks the bottom of the plowshare, after the plowshare comes into contact with the stone, as the plowshare moves forward, the stone will exert a reverse force on the plowshare. At this time, the corresponding plowshare holder will elastically lift together with the plowshare. When passing over the obstacle, the limiting sleeve set on the plowshare holder slides upward along the vertical section of the limiting rod for a certain distance. At the same time, the first hook spring, which is in a stretched state, will be further stretched. After passing over the obstacle, the first hook spring will pull the plowshare holder again, so that it abuts against the top of the horizontal bending section of the limiting rod again. At the same time, after passing over the obstacle, the plowshare will also reset and continue to work.

[0016] Second, in this invention, when traversing undulating ground, the support wheel rolls upward along the undulating ground and simultaneously lifts the plowshare holder upward via the limiting rod, thereby causing the plowshare to move together with the support wheel. At the same time, the first hook spring, which is in a stretched state, is further stretched. When the ground level drops, the support wheel rolls downward along the ground and stops lifting the plowshare holder upward. At this time, the first hook spring, which is in a stretched state, contracts and pulls the plowshare holder downward, thereby causing the plowshare holder and the plowshare set on the plowshare holder to move downward together with the support wheel, avoiding the problem of the plowshare penetrating too deeply into the soil on undulating slopes and being suspended and plowing empty in low-lying areas.

[0017] Third, in this invention, the first hook spring in the stretched state can continuously tighten the plowshare holder, ensuring that the plowshare always remains in contact with the bottom of the dug furrow.

[0018] Fourth, in this invention, the limiting rod can limit the plowshare holder to prevent the plowshare from sinking too much and causing the furrow to be dug too deep.

[0019] Fifth, in this invention, the second hook spring in the tensioned state can continuously tighten the roller bracket to ensure that the vibrating roller always keeps in contact with the ground. As the driving vehicle moves forward, after the plow has opened the furrows and the seeds have fallen into the furrows through the seed collection tube, the vibrating roller can compact and level the seeds and furrows during the forward movement.

[0020] VI. In this invention, different types of seeds can be separated by multiple seed storage cavities. When in use, the staff pour different types of seeds into each seed storage cavity as needed. As the corresponding inoculation disc rotates, the seeds in each seed storage cavity can be quantitatively discharged into the same seed collection tube for mixing, and then discharged through the seed collection tube for sowing.

[0021] VII. In this invention, if it is necessary to stop the delivery of seeds from a certain seed storage cavity to a certain seed collection tube, it is not necessary to stop the corresponding connecting shaft from rotating. It is only necessary to release the locking structure between the inoculation disc and the connecting shaft. At the same time, it does not affect the driving of the connecting shaft to other inoculation discs. The staff can independently control the flow of seeds entering a single seed collection tube according to the actual planting needs.

[0022] 8. In this invention, the locking sleeve is a transparent structure to facilitate the insertion of the first insertion rod into the first positioning slot. Attached Figure Description

[0025] 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.

[0026] Example 1 like Figures 1-16 As shown, a seeding device for various complex terrains includes a drive vehicle body 11. A connecting rod 12 is rotatably connected to one side of the drive vehicle body 11 via a first connecting bracket 111. The connecting rod 12 is provided with multiple connecting rod structures, including a side docking seat 21 fixed to the connecting rod 12 and a plow head seat 22 with a hollow interior. An upper connecting rod 23 is rotatably connected to the side of the side docking seat 21 away from the connecting rod 12, and lower connecting rods 24 are symmetrically rotatably connected to both sides of the side docking seat 21. The free end of the upper connecting rod 23 is rotatably connected to the inside of the plowshare holder 22, and the free ends of the two lower connecting rods 24 are symmetrically rotatably connected to both sides of the plowshare holder 22. The same first hook spring 25 is movably suspended between the two lower connecting rods 24, and the other end of the first hook spring 25 is movably suspended on the upper connecting rod 23; The plowshare holder 22 is equipped with a plowshare 31; The drive vehicle 11 drives the plow head 31 to move through the first connecting bracket 111, the connecting rod 12 and the linkage structure. The plow head 31 can open a furrow for sowing in the soil. The linkage structure can pull the corresponding plow head 31 individually. When one plow head 31 encounters an obstacle, the corresponding linkage structure can make the plow head 31 avoid the obstacle, while the other plow heads 31 maintain their original working state.

[0027] Combination Figures 1-3 , Figures 9-11 A seed box 61 is installed on the side of the drive vehicle body 11 away from the plow head 31 via a second connecting bracket 112. The seed box 61 has at least two seed storage cavities 6101 inside. The bottom of each seed storage cavity 6101 is fixedly connected to multiple seed-dropping structures. The seed-dropping structures at the bottom of the two seed storage cavities 6101 are set one-to-one, and the outlets of the corresponding two seed-dropping structures are connected to the same seed collection pipe 75. The staff pours different types of seeds into the two seed storage cavities 6101 as needed. The seeds in the two seed storage cavities 6101 can be quantitatively discharged into the seed collection pipe 75 for mixing through the set seed-dropping structures. Multiple seed collection tubes 75 correspond one-to-one with multiple plow heads 31, and along the direction of travel of the drive vehicle body 11, the discharge end of the seed collection tube 75 is fixed to the rear side of the plow head 31. During the process of the plow head 31 opening furrows, the mixed seeds fall into the opened furrows through the seed collection tubes 75.

[0028] Furthermore, such as Figures 1-4 As shown, multiple side docking brackets 21 are equidistantly fixed to the connecting rod 12; The upper link 23 is located above the two lower links 24, and the upper link 23 is parallel to the two lower links 24; The two lower connecting rods 24 are fixedly connected to the same first connecting shaft 244, and the first connecting shaft 244 is located on the side of the two lower connecting rods 24 near the side docking seat 21. The bottom of the upper connecting rod 23 away from the side docking seat 21 is fixedly connected to the first hook spring seat 231. The same first hook spring 25 is movably hung between the first connecting shaft 244 and the first hook spring seat 231, and the first hook spring 25 is in a stretched state.

[0029] Furthermore, such as Figure 5 As shown, the plowshare holder 22 has an insertion groove 2201 inside. An insertion rod 311 is fixedly connected to the top of the plowshare 31. When installing the plowshare 31, the insertion rod 311 is inserted into the insertion groove 2201. Multiple through holes 2601 are correspondingly opened on the inner wall of the insertion groove 2201 and on the insertion rod 311. Two through holes 2601 located at the same height on the inner wall of the insertion groove 2201 and on the insertion rod 311 are connected to the same pin 26. The pin 26 allows the insertion rod 311 to be inserted... Locked and fixed to the plow head holder 22, the operator can adjust the vertical height of the plow head 31 according to the desired furrow depth. During adjustment, first pull out the pin 26, and then drive the connecting rod 311 to move vertically up and down along the connecting groove 2201 according to the target furrow depth. After adjustment, the pin 26 can be reinserted into the corresponding through hole 2601. During operation, the first hook spring 25, which is in a stretched state, can continuously tighten the plow head holder 22 to ensure that the plow head 31 always remains in contact with the bottom of the furrow.

[0030] Furthermore, such as Figures 3-6 As shown, a limiting sleeve 27 is fixedly connected inside the plowshare holder 22. An L-shaped limiting rod 41 is slidably connected inside the limiting sleeve 27. One end of the limiting rod 41 is rotatably connected to a support wheel 42 via a bracket. The horizontal bend of the limiting rod 41 is located below the plowshare holder 22, and its end extends out from one side of the plowshare holder 22. The bottom of the plowshare holder 22 abuts against the top of the horizontal bend of the limiting rod 41. The top of the limiting rod 41 extends into the limiting sleeve 27, and the top end is threadedly connected to the limiting nut 43. The bottom of the limiting nut 43 abuts against the top of the limiting sleeve 27. The support roller 42 is located on one side of the plowshare 31.

[0031] When installing the support roller 42, insert the top of the limiting rod 41 along the bottom of the limiting sleeve 27. After the top of the limiting rod 41 extends out of the limiting sleeve 27, thread a limiting nut 43 onto the top of the limiting rod 41. The limiting nut 43 can limit the top of the limiting rod 41 to prevent the limiting rod 41 from slipping out of the limiting sleeve 27.

[0032] During operation, the support roller 42 contacts the ground, and the plow head 31 penetrates the soil under the tension of the first hook spring 25. As the plow head 31 moves downward, the limiting sleeve 27 set on the plow head holder 22 also slides downward along the vertical section of the limiting rod 41. When the bottom of the plow head holder 22 abuts against the top of the horizontal bending section of the limiting rod 41, the ground will exert a reverse force on the plow head holder 22 through the support roller 42 and the limiting rod 41, preventing the plow head 31 from descending and preventing it from sinking too much, which would cause the furrow to be dug too deep.

[0033] While the first hook spring 25 tightens the plowshare holder 22, it does not completely lock the plowshare holder 22. During the digging process, if a hard obstacle such as a stone blocks the bottom of the plowshare 31, after the plowshare 31 comes into contact with the stone, the stone will exert a reverse force on the plowshare 31 as it moves forward. At this time, the corresponding plowshare holder 22 will elastically lift together with the plowshare 31. When it passes the obstacle, the limiting sleeve 27 set on the plowshare holder 22 slides upward along the vertical section of the limiting rod 41 for a certain distance. At the same time, the first hook spring 25, which is in a stretched state, will be further stretched. After passing the obstacle, the first hook spring 25 will pull the plowshare holder 22 again, so that it abuts against the top of the horizontal bending section of the limiting rod 41 again. At the same time, after passing the obstacle, the plowshare 31 will also reset and continue to work.

[0034] When traversing undulating ground, the support roller 42 rolls upward along the undulating ground and simultaneously lifts the plowshare holder 22 upward via the limit rod 41, thereby causing the plowshare 31 to move together with the support roller 42. At the same time, the first hook spring 25, which is in a stretched state, is further stretched. When the ground level drops, the support roller 42 rolls downward along the ground and stops lifting the plowshare holder 22 upward. At this time, the first hook spring 25, which is in a stretched state, contracts and pulls the plowshare holder 22 downward, thereby causing the plowshare holder 22 and the plowshare 31 set on the plowshare holder 22 to move downward together with the support roller 42. This avoids the plowshare 31 from penetrating too deeply into the soil on undulating slopes and from being suspended and plowing empty in low-lying areas.

[0035] Furthermore, such as Figure 2 , Figure 3 and Figure 7 As shown, it also includes a vibratory roller 52. The end of the plowshare holder 22 away from the upper connecting rod 23 is rotatably connected to a roller bracket 51. The roller bracket 51 is inclined and the high end of the roller bracket 51 is rotatably connected to the plowshare holder 22. The vibratory roller 52 is rotatably connected to the low end of the roller bracket 51. Along the direction of travel of the drive vehicle 11, the vibratory roller 52 is located directly behind the plowshare 31; A second connecting shaft 221 is fixedly connected to the bottom of the plowshare holder 22 near the roller bracket 51. A second hook spring holder 511 is fixedly connected to the bottom of the roller bracket 51. The same second hook spring 53 is movably hung between the second connecting shaft 221 and the second hook spring holder 511. The second hook spring 53 is in a stretched state. During operation, the stretched second hook spring 53 can continuously tighten the roller bracket 51 to ensure that the vibrating roller 52 always keeps in contact with the ground. As the drive vehicle 11 moves forward, after the plowshare 31 has opened the furrows and the seeds have fallen into the furrows through the seed collection tube 75, the vibrating roller 52 compacts and flattens the seeds and furrows during the forward movement.

[0036] Furthermore, such as Figure 9 As shown, the top of the second connecting bracket 112 is symmetrically fixed with a heightening support plate 118, and the seed box 61 is fixed between the two heightening support plates 118. like Figure 11 As shown, the seed collection tube 75 is snapped onto the bottom of the second connecting bracket 112. Multiple fans 14, each corresponding to a seed collection tube 75, are fixedly installed on the second connecting bracket 112. The air inlet of the seed collection tube 75 is connected to the exhaust port of the corresponding fan 14. The air inlets of multiple seed collection tubes 75 are connected to the exhaust ports of the fans 14 through pipes. The other end of the seed collection tube 75 is the discharge port. When the seeds in multiple seed storage cavities 6101 are discharged into the corresponding seed collection tube 75 through the seed-laying structure, the fans 14 can blow the seeds out from the discharge port of the seed collection tube 75. The seeds of multiple varieties falling into the same seed collection tube 75 will also mix while moving.

[0037] Among them, such as Figure 9 As shown, there are preferably three seed storage cavities 6101. The seeding structure includes an outer protective shell 71. The outer protective shell 71 is hollow inside and has openings at the top and bottom. The top opening of the outer protective shell 71 is fixedly connected to the corresponding seed storage cavity 6101. like Figure 12 As shown, three seed inlets 7501 are fixedly connected to the seed collection tube 75, and the bottom openings of the three corresponding outer protective shells 71 are connected to the seed inlets 7501 through the seed delivery tube 73 respectively. An inoculation disc 72 is rotatably connected inside the outer protective shell 71. The inoculation disc 72 is located between the top opening and the bottom opening of the outer protective shell 71, and the inoculation disc 72 separates the top opening and the bottom opening of the outer protective shell 71. The surface of the inoculation disc 72 is provided with multiple recesses 7201 in a circumferential shape. A hollow sleeve 721 is integrally provided on the axis of the inoculation disc 72, and the two ends of the hollow sleeve 721 are rotatably connected to the inner wall of the outer protective shell 71. like Figure 9 and Figure 11 As shown, three connecting shafts 74, corresponding one-to-one with the seed storage cavities 6101, are rotatably connected between the two raised support plates 118. All three connecting shafts 74 are located at the bottom of the seed box 61, and multiple hollow sleeves 721 corresponding to the same seed storage cavity 6101 are slidably fitted onto the same connecting shaft 74. Locking structures are provided on the side walls of multiple outer protective shells 71, and multiple hollow sleeves 721 are locked to the connecting shafts 74 through corresponding locking structures. By setting the connecting shafts 74, multiple inoculation discs 72 located at the bottom of the same seed storage cavity 6101 can be connected in series. The locking structures can lock the hollow sleeves 721 to the corresponding connecting shafts 74, and the connecting shafts 74 drive the inoculation discs 72 to rotate. Specifically, as shown... Figures 13-16 As shown, the locking structure includes a locking sleeve 81 and a threaded rod 82. One end of the hollow sleeve 721 extends out of the outer protective shell 71 and the locking sleeve 81 is fixedly connected to the end. The locking sleeve 81 is slidably sleeved on the connecting shaft 74. The locking sleeve 81 has a threaded hole 8101. The threaded rod 82 is threadedly engaged with the threaded hole 8101. The connecting shaft 74 has a plurality of first positioning slots 7401 that correspond one-to-one with the threaded holes 8101. The end of the threaded rod 82 near the connecting shaft 74 is integrally provided with a first insertion rod 821 that is adapted to the first positioning slot 7401. A connecting ear 711 is fixedly connected to the side of the outer protective shell 71 near the locking sleeve 81. A second positioning slot 7101 is provided on the connecting ear 711. A threaded rod 82 extends from one end near the connecting ear 711 into a threaded hole 8101, and a second insert rod 822 adapted to the second positioning slot 7101 is integrally provided at the end. Specifically, during locking, the threaded rod 82 is rotated, and under the action of thread engagement, the threaded rod 82 moves along the direction close to the first positioning slot 7401. When the first insertion rod 821 is inserted into the first positioning slot 7401, the connecting shaft 74 rotates, which drives the locking sleeve 81 to rotate together through the first insertion rod 821, thereby driving the corresponding inoculation disc 72 to rotate. At this time, the inoculation disc 72 will send the seeds in the corresponding seed storage cavity 6101 to the corresponding seed collection tube 75 during the rotation. The multiple seed storage cavities 6101 can separate different types of seeds. When in use, the staff pour different types of seeds into each seed storage cavity 6101 as needed. As the corresponding inoculation disc 72 rotates, the seeds in each seed storage cavity 6101 can be quantitatively discharged into the same seed collection tube 75 for mixing, and then discharged through the seed collection tube 75 for sowing. To stop the delivery of seeds from a seed storage cavity 6101 to a seed collection tube 75, simply reverse the threaded rod 82. The threaded rod 82 moves away from the connecting shaft 74. When the first insertion rod 821 separates from the first positioning slot 7401, the threaded rod 82 will no longer drive the locking sleeve 81 to rotate via the first insertion rod 821. Continue to reverse the threaded rod 82. When the second insertion rod 822 is inserted into the second positioning slot 7101, the connecting ear 711 can limit the threaded rod 82 via the second insertion rod 822, thereby limiting the locking sleeve 81 and the hollow sleeve 721 fixed to the locking sleeve 81. This prevents the corresponding hollow sleeve 721, which is slidably sleeved on the connecting shaft 74, from passively rotating with the rotation of the connecting shaft 74 after the locking sleeve 81 stops locking with the connecting shaft 74, thus causing the corresponding inoculation disc 72 to deliver the seeds.

[0038] When the first insertion rod 821 is in the insertion state with the first positioning slot 7401, the second insertion rod 822 is in the separation state with the second positioning slot 7101; this prevents the second insertion rod 822 from interfering with the connecting ear 711 when the connecting shaft 74 drives the locking sleeve 81 to rotate through the first insertion rod 821. When the second insertion rod 822 is in the insertion state with the second positioning slot 7101, the first insertion rod 821 is in the separation state with the first positioning slot 7401, so as to avoid interference between the first insertion rod 821 and the corresponding serial shaft 74 when the second insertion rod 822 is in the insertion state with the second positioning slot 7101.

[0039] The locking sleeve 81 is transparent to facilitate the insertion of the first insertion rod 821 into the first positioning slot 7401. Among them, the threaded rod 82 extends out of the threaded hole 8101 and is fixedly connected in a circular shape with a lever 823 so that the operator can rotate the threaded rod 82.

[0040] Furthermore, such as Figure 9 and Figure 10 As shown, the same end of each of the three tandem shafts 74 extends a heightening support plate 118; A driven chain 93 is fixedly sleeved on the shaft of the extension plate 118 extending from the edge of the connecting shaft 74. A drive motor 91 is fixedly installed on the side of the extension plate 118 away from the driven chain 93. The output shaft of the drive motor 91 passes through the extension plate 118 and a drive chain 92 is fixedly sleeved at its end. The drive chain 92 and the driven chain 93 are meshed with the same first transmission chain 94. A first synchronous chain 95 is also fixedly sleeved on the shaft of the extension plate 118 extending from the connecting shaft 74. A first synchronous chain 95 and a second synchronous chain 96 are fixedly sleeved on the shaft of the extension plate 118 extending from the connecting shaft 74 adjacent to the connecting shaft 74. The two first synchronous chain 95s are meshed with the same second transmission chain 97. Another tandem shaft 74 extends from the shaft of the heightened support plate 118 and is fixedly fitted with a second synchronous toothed plate 96. The two second synchronous toothed plates 96 are engaged with the same third transmission chain 98. The number of teeth on the active toothed disc 92 is less than the number of teeth on the driven toothed disc 93, thereby reducing the rotational speed of the driven toothed disc 93 and increasing the torque. This prevents the seeding disc 72 from rotating too fast with the output shaft of the drive motor 91, causing the seeds to be discharged too quickly and thus clogging the seed delivery tube 73.

[0041] Specifically, when driving the three tandem shafts 74 to rotate, the drive motor 91 is turned on, and the output shaft of the drive motor 91 drives the active crank 92 to rotate. Under meshing, the active crank 92 drives the driven crank 93 to rotate through the first transmission chain 94. The driven crank 93 drives the corresponding tandem shaft 74 to rotate. When the tandem shaft 74 rotates, it drives the first synchronous crank 95 fixedly sleeved on its shaft to rotate. Under meshing, the first synchronous crank 95 drives another first synchronous crank 95 to rotate through the second transmission chain 97, thereby driving the tandem shaft 74 adjacent to the tandem shaft 74 and the second synchronous crank 96 fixedly sleeved on its shaft to rotate. Under meshing, the second synchronous crank 96 drives another second synchronous crank 96 to rotate through the third transmission chain 98. At this time, all three tandem shafts 74 are in a rotating state. Furthermore, in combination Figure 2 , Figure 3 and Figure 8The top of the first connecting bracket 111 is integrally provided with a gantry bracket 113. The top of the gantry bracket 113 is rotatably connected to a hydraulic telescopic rod 13. The bottom of the first connecting bracket 111 is symmetrically rotatably connected to a first connecting arm 114 on the side away from the connecting rod 12. The two first connecting arms 114 are fixedly connected to the same third connecting shaft 115. The telescopic end of the hydraulic telescopic rod 13 is movably sleeved on the third connecting shaft 115. The two ends of the third connecting shaft 115 extend from the two first connecting arms 114 respectively, and the two ends of the third connecting shaft 115 are rotatably connected to a second connecting arm 116 respectively. The second connecting arm 116 is arc-shaped. A card seat 117 is fixedly connected to the connecting rod 12. The free ends of the two second connecting arms 116 are rotatably connected to the two sides of the card seat 117 respectively.

[0042] After the work is completed, control the hydraulic telescopic rod 13 to extend its telescopic end. At the same time, the telescopic end of the hydraulic telescopic rod 13 will push the first connecting arm 114 through the third connecting shaft 115. At this time, the first connecting arm 114 will rotate counterclockwise by a certain angle. While the first connecting arm 114 is rotating, it will also pull the connecting rod 12 through the second connecting arm 116, causing it to rotate counterclockwise along the first connecting bracket 111. This will lift the connecting rod structure and plow head 31 set on the connecting rod 12, so as to drive the vehicle body 11 away.

[0043] The first connecting arm 114 and the second connecting arm 116 can raise the connecting rod 12 higher. If the telescopic end of the hydraulic telescopic rod 13 is directly fixed to the card seat 117, when the telescopic end of the hydraulic telescopic rod 13 pulls the connecting rod 12 to rise through the card seat 117, the travel of the telescopic end of the hydraulic telescopic rod 13 when it drives the card seat 117 to move is limited because the hydraulic telescopic rod 13 itself occupies a certain space. This results in the limited lifting height of the connecting rod 12.

[0044] In summary, the workflow of this invention is as follows: The drive vehicle 11 drives the plow head 31 to move through the first connecting bracket 111 and the linkage structure. Multiple plow heads 31 open multiple furrows for sowing in the soil. During the digging process, if a hard obstacle such as a stone blocks the bottom of the plow head 31, the plow head 31 will exert a reverse force on the plow head 31 as it moves forward. At this time, the corresponding plow head holder 22 will elastically lift together with the plow head 31. When it passes the obstacle, the limiting sleeve 27 set on the plow head holder 22 slides upward along the vertical section of the limiting rod 41 for a certain distance. At the same time, the first hook spring 25, which is in a stretched state, will be further stretched. After passing the obstacle, the first hook spring 25 will pull the plow head holder 22 again, so that it abuts against the top of the horizontal bending section of the limiting rod 41 again. At the same time, the plow head 31 will also reset after passing the obstacle and continue to work. At the same time, the drive motor 91 is turned on, and the output shaft of the drive motor 91 drives the active crank 92 to rotate. Under meshing, the active crank 92 drives the driven crank 93 to rotate through the first transmission chain 94. The driven crank 93 drives the corresponding tandem shaft 74 to rotate. When the tandem shaft 74 rotates, it drives the first synchronous crank 95 fixedly sleeved on its shaft to rotate. Under meshing, the first synchronous crank 95 drives another first synchronous crank 95 to rotate through the second transmission chain 97, thereby driving the tandem shaft 74 adjacent to the tandem shaft 74 and the second synchronous crank 96 fixedly sleeved on its shaft to rotate. Under meshing, the second synchronous crank 96 drives another second synchronous crank 96 to rotate through the third transmission chain 98. At this time, all three tandem shafts 74 are in a rotating state. When the tandem shaft 74 rotates, it will drive the corresponding inoculation disc 72 to rotate through the locking structure. When the inoculation disc 72 rotates, when the concave opening 7201 is connected to the seed storage cavity 6101, the seeds in the seed storage cavity 6101 will fall into the concave opening 7201 through the top opening of the outer protective shell 71. As the inoculation disc 72 rotates, the concave opening 7201 stops communicating with the top opening of the outer protective shell 71 and begins to communicate with the bottom opening of the outer protective shell 71. At this time, the seeds in the concave opening 7201 will fall into the seed delivery tube 73 through the bottom opening of the outer protective shell 71 and be sent to the seed collection tube 75 through the seed delivery tube 73. After the seeds of multiple varieties enter the same seed collection tube 75, the fans 14 will mix the seeds sent into the same seed collection tube 75 and discharge them into the corresponding furrows. As the drive vehicle 11 moves forward, after the plow 31 has opened the furrows and the seeds have fallen into the furrows through the seed collection tube 75, the vibrating roller 52 compacts and flattens the seeds and furrows during the forward movement. After the work is completed, control the hydraulic telescopic rod 13 to extend its telescopic end. At the same time, the telescopic end of the hydraulic telescopic rod 13 will push the first connecting arm 114 through the third connecting shaft 115. At this time, the first connecting arm 114 will rotate counterclockwise by a certain angle. While the first connecting arm 114 is rotating, it will also pull the connecting rod 12 through the second connecting arm 116, causing it to rotate counterclockwise along the first connecting bracket 111. This will lift the connecting rod structure and plow head 31 set on the connecting rod 12, and then drive the vehicle body 11 away.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive vehicle body 11, the hydraulic telescopic rod 13 and the drive motor 91 are commonplace and are all conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
