Description

Technical Field

[0001] This invention relates to the field of agricultural planting equipment, and in particular to a garlic planter. Background Technology

[0002] Garlic, as an important economic crop, has unique planting characteristics due to the significant differences in clove size. While traditional garlic planters integrate land preparation (rotary tillage and ridging) with planting, they face numerous technical bottlenecks in practical applications. The main issue is that existing equipment uses fixed welded connections or bolt fastening, making it impossible to quickly replace planting components to suit different garlic varieties. When planting large garlic varieties like single-clove garlic using combined garlic planters, the fixed-size seed scoop and guide tube are prone to jamming, while planting smaller varieties like multi-clove garlic results in missed plantings, severely impacting planting quality. Changing the planting structure of traditional combined garlic land preparation and planting equipment requires disassembling numerous bolts and even cutting welded parts, which is time-consuming and significantly reduces operational efficiency. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art by designing a garlic planter.

[0004] The technical solution of the present invention to achieve the above objectives is a garlic planter, comprising a rotary tillage structure, a fixing block, a frame, a ridging structure, a planting structure, a pressing structure, a connecting rod, and a tensioning structure;

[0010] Furthermore, the sowing structure includes a sowing box, a seed storage chamber, a sowing cavity, adjusting plates, support frames, a rotating shaft, connecting gears, a seed scoop, a power motor, a furrow opener, and a conveyor cylinder. The sowing box is fixedly installed on the frame and is divided into an upper seed storage chamber and a lower sowing cavity. Multiple adjusting plates are slidably installed inside the seed storage chamber, and multiple support frames are fixedly installed inside the sowing cavity. The rotating shaft is rotatably mounted on the frame at both ends. Multiple sets of connecting gears are installed within the sowing structure. Each set of connecting gears has three gears arranged in a triangle and driven by a chain. One gear in each set is fixedly installed on the rotating shaft, and the other two gears in each set are connected by a chain. Each of the above and below the support frame is rotatably mounted. The number of support frames is the same as the number of sets of connecting gears. Multiple seeding scoops are fixedly mounted on the chain of each set of connecting gears. The power motor is fixedly mounted on the frame. The power motor has two output ends.

[0016] In summary, this invention provides a garlic planter with the following advantages: Through its structural design, the device utilizes a detachable tensioning structure and fixing blocks to achieve rapid connection and replacement of the rotary tillage structure, ridging structure, and planting structure. This design leverages the adjustable function of the tensioning structure to precisely align and reliably fix the rotary tillage structure, frame, and planting structure. The entire assembly process requires only simple tools, greatly improving the equipment's assembly efficiency. Users can quickly select and replace the appropriate planting structure according to different garlic varieties (such as single-clove garlic, multi-clove garlic, etc.), perfectly adapting to the planting needs of various garlic varieties, or promptly replacing and repairing any damaged individual structure. Compared to traditional garlic planters that use fixed welding or bolt-fastening connections, this invention solves the problem of needing to disassemble a large number of parts or even cut welded areas when replacing planting components, shortening replacement time and improving work efficiency.

[0032] First Embodiment

[0033] Please see Figure 1 and Figure 2 This invention provides a technical solution: a garlic planter, comprising a rotary tillage structure 1, a fixing block 2, a frame 3, a ridging structure 4, a planting structure 5, a compaction structure 6, a connecting rod 7, and a tensioning structure 8. The input end of the gearbox of the rotary tillage structure 1 is connected to the rear output shaft of the gearbox of an agricultural tractor via a universal joint, and the output end is connected to the ridging structure 4 via a chain drive, used to chop weeds and roots of previous crops and break up compacted soil.

[0034] The rotary tillage structure 1 is equipped with a steel plate with multiple round holes. Multiple fixing blocks 2 are detachably mounted on the steel plate with multiple round holes on one end via bolts. The multiple round holes on the steel plate on the rotary tillage structure 1 facilitate the alignment and connection of the fixing blocks 2 with the rotary tillage structure 1 using bolts. The other end of the multiple fixing blocks 2 is detachably mounted on the frame 3 via U-shaped screws. One end of the fixing block 2 is connected to the rotary tillage structure 1, and the other end is connected to the frame 3, thereby fixing the frame 3 and the rotary tillage structure 1 together.

[0035] The ridging structure 4 can be detachably installed on the frame 3 by means of U-shaped screws or bolts. In this embodiment, U-shaped screws are used to detachably install the ridging structure 4 on the frame 3. The ridging structure 4 is used to gather the loose soil after rotary tillage towards the center to form a ridge.

[0036] The sowing structure 5 is fixedly installed on the frame 3, and the seed landing position is aligned with the bottom of the ridge formed by the ridging structure 4 to guide the seed to the bottom of the ridge. The sowing structure 5 is equipped with a motor, which provides power to the sowing structure 5 and the pressing structure 6. The sowing structure 5 and the pressing structure 6 are driven by a chain.

[0037] The compaction structure 6 is fixedly installed on the frame 3. The power source is provided by the sowing structure 5 through chain drive, which drives the compaction structure 6 to compact the soil around the seed furrow and level the ridge surface.

[0038] One end of the connecting rod 7 is fixedly installed on the compaction structure 6, and the other end is fixedly installed on the sowing structure 5, used to connect the sowing structure 5 and the compaction structure 6. The end of the connecting rod 7 extends out of the sowing structure 5, and the part extending out of the sowing structure 5 forms a triangle with the multiple fixing blocks 2 on the frame 3 as the vertex, making the connection between the combined rotary tillage structure 1 and the frame 3 more stable and preventing it from shaking during use.

[0039] One end of the tensioning structure 8 is installed on the rotary tillage structure 1, and the other end is installed on the end of the connecting rod 7 that extends out of the seeding structure 5, for pulling the rotary tillage structure 1 and the connecting rod 7 toward each other.

[0040] Before operation, the input end of the rotary tiller 1 is connected to the rear output shaft of the agricultural tractor's gearbox via a universal joint. A suitable sowing structure 5 is selected based on the size of the garlic seeds to be sown. The sowing structure 5 and the pressing structure 6 are fixedly mounted on the same frame, and are simultaneously fixedly connected to both structures via a connecting rod 7 at the top. The end of the connecting rod 7 extends beyond the sowing structure 5.

[0041] After the fixing block 2 and the ridging structure 4 are installed on the frame 3 by U-shaped screws, the frame 3 and the rotary tillage structure 1 are pulled towards each other by the tensioning structure 8. During the pulling process, the fixing block 2 is gradually aligned with the steel plate part with the round hole on the rotary tillage structure 1. After precise alignment, the fixing block 2 is connected to the rotary tillage structure 1 by bolts, thus completing the assembly of the present invention.

[0042] During operation, the front section consists of a rotary tillage structure 1 and a ridging structure 4. An agricultural tractor provides power to the front section, driving the entire invention along the direction of travel and simultaneously operating the rotary tillage structure 1. The rotary tillage structure 1 thoroughly crushes the previous crop residue and clods, loosens the soil, improves aeration and water retention, creating a level seedbed for subsequent sowing, and also shreds weeds and the roots of the previous crop. The tilled soil then enters the ridging structure's operating area. The gearbox of the ridging structure 4 is connected to the gearbox of the rotary tillage structure 1 via a chain drive, and the rotary tillage structure 1 transmits power to the ridging structure 4 through the chain. As the rotary tillage structure 1 operates, it drives the ridging structure 4 simultaneously. The blades of the ridging structure 4 spiral in a counter-rotating manner, pushing the soil from both sides towards the center and continuously piling it up during travel, forming a regular ridge.

[0043] The latter half consists of the sowing structure 5 and the compaction structure 6. The sowing structure 5 provides the power source for the latter half. The motor within the sowing structure 5 drives the compaction structure 5 itself, while simultaneously transmitting power to the compaction structure 6 via a chain. During operation, the sowing structure 5 drops the garlic seeds into the ridge bottom. Because the sowing position of the sowing structure 5 corresponds to the ridge bottom position formed by the ridging structure 4 during operation, the seeds can fall more accurately into the ridge bottom. The lower ridge bottom helps retain moisture better, reduces evaporation, and is beneficial for seed germination and growth. Finally, the compaction structure 6 compacts the soil, ensuring close contact between the seeds and the soil to promote water absorption and germination, while also leveling the ridge surface, facilitating subsequent field management (such as irrigation and spraying).

[0044] Please see Figure 3The rotary tillage structure 1 includes a rotary tillage shell 11, a connecting bracket 12, a first gearbox 13, a rotary tillage shaft 14, and rotary tillage blades 15. The connecting bracket 12 is fixedly installed at the center of the upper surface of the rotary tillage shell 11. The connecting bracket 12 provides a position for connecting the rotary tillage structure 1 to the agricultural tractor, allowing the agricultural tractor to drive the rotary tillage structure 1 to move, thus enabling the overall structure of the invention to move along the trajectory of the agricultural tractor. One end of the tensioning structure 8 is installed on the connecting bracket 12. The first gearbox 13 is fixedly installed on the rotary tillage shell 11, and the input end of the first gearbox 13 is connected to the agricultural tractor's... The output shaft of the gearbox is connected by a universal joint. The first gearbox 13 has three output ends. One output end is located above the first gearbox 13 and is connected to the ridging structure 4 by a chain. The other two output ends are located on the lower sides of the first gearbox 13 and are on the same axis. The ends of the two rotary tillage blade shafts 14 facing the center of the rotary tillage structure 1 are fixedly connected to one of the output ends below the first gearbox 13. The ends of the two rotary tillage blade shafts 14 facing the sides of the rotary tillage structure 1 are rotatably connected to the rotary tillage housing 11. Multiple rotary tillage blades 15 are fixedly installed on the rotary tillage blade shafts 14 and are equidistantly distributed on the rotary tillage blade shafts 14.

[0045] During operation, the input shaft of the first gearbox 13 is driven to rotate by the output shaft of the agricultural tractor's gearbox, causing all three output shafts of the first gearbox 13 to rotate simultaneously. The output shaft located above the first gearbox 13 is connected to the ridging structure 4 via a chain, providing power to the ridging structure 4. The other two output shafts located below the first gearbox 13 drive the rotary tiller shaft 14 to rotate within the rotary tiller housing 11. The rotation of the rotary tiller shaft 14 drives the rotary tiller blades 14 to rotate, thoroughly crushing previous crop residues and clods, loosening the soil, improving soil aeration and water retention, and creating a level seedbed for subsequent sowing.

[0046] Please see Figure 1 The rotary tiller housing 11 is equipped with a hinged plate 9, one side of which is hinged to the rotary tiller housing 11. When it is necessary to repair or replace parts inside the rotary tiller structure 1, the hinged plate 9 can be opened on the rotary tiller housing 11 via the hinge, making it convenient for maintenance personnel to inspect and work.

[0047] Please see Figure 3The ridging structure 4 includes a ridging support 41, a second gearbox 42, ridging shafts 43, and spiral blades 44. Two lifting frames are detachably mounted on the frame 3. The function of the lifting frames is to adjust the height of the ridging support 41 by rotating a rotatable handle located above the lifting frame, thereby changing the height of the spiral blades 44. This is a common technique used by those skilled in the art. The ridging support 41 is fixedly installed below the lifting frames. The second gearbox 42 is fixedly installed on the ridging support 41. The input end of the second gearbox 42 is connected to the rotary tillage structure 1 via a chain drive. The two output ends of the second gearbox 42 are located on both sides below the second gearbox 42 and are on the same axis. One end of each of the two ridging shafts 43 facing the center of the ridging support 41 is fixedly connected to one of the output ends below the second gearbox 42. The ends of the two ridging shafts 43 facing both ends of the ridging support 41 are rotatably connected to the ridging support 41. The spiral blades 44 are fixedly installed on the ridging shafts 43. The spiral blades 44 on the two ridging shafts 43 rotate in opposite directions, used to gather the loose soil after rotary tillage towards the center.

[0048] During operation, the rotary tillage structure 1 transmits power via a chain to the input end of the second gearbox 42, causing the two output ends of the second gearbox 42 to rotate. The rotation of the two output ends of the second gearbox 42 drives the ridging shaft 43 to rotate on the ridging support 41. The rotation of the ridging shaft 43 drives the spiral blades 44 to rotate. The two spiral blades 44 rotate in opposite directions, gathering the loose soil after rotary tillage towards the center. The reverse spiral design pushes the soil on both sides towards the center, continuously piling it up during the process to form a ridge.

[0049] Please see Figures 4-7The sowing structure 5 includes a sowing box 51, a seed storage chamber 511, a sowing chamber 512, an adjusting plate 52, a support frame 53, a rotating shaft 54, a connecting gear 55, a seed scoop 56, a power motor 57, a furrow opener 58, and a conveyor cylinder 59. The sowing box 51 is fixedly installed on the frame 3. The sowing box 51 is divided into an upper seed storage chamber 511 and a lower sowing chamber 512. Multiple adjusting plates 52 are slidably installed in the seed storage chamber 511. Multiple support frames 53 are fixedly installed in the sowing chamber 512. The rotating shaft 54 ​​is rotatably installed on the frame 3 at both ends. Multiple sets of connecting gears 55 are installed in the sowing structure 5. Each set of connecting gears 55 has three gears arranged in a triangle and driven by a chain. One of the connecting gears 55 in each set is fixedly installed on the rotating shaft 54. Two other connecting gears 55 are rotatably mounted on the upper and lower ends of a support frame 53. The number of support frames 53 is the same as the number of groups formed by the connecting gears 55. Multiple seeding spoons 56 are fixedly mounted on the chain that drives each group of connecting gears 55. The power motor 57 is fixedly mounted on the frame 3. The power motor 57 has two output ends. One output end is driven by a gear to the rotating shaft 54, and the other output end is driven by a chain to the pressing structure 6. Multiple furrow openers 58 are fixedly mounted below the frame 3. The number of furrow openers 58 is the same as the number of support frames 53. Multiple conveyor cylinders 59 are fixedly mounted on the seed box 51. The number of conveyor cylinders 59 is the same as the number of furrow openers 58. The discharge port at the end of the conveyor cylinder 59 is aligned with the position of the furrow opener 58.

[0050] Before planting, garlic cloves are placed in the seed storage chamber 511 above the planting box 51. The position of the adjusting plates 52 on the seed storage chamber 511 is adjusted according to the required planting spacing. Multiple adjusting plates 52 are evenly distributed on the seed storage chamber 511. The adjusting plates 52 slide on the seed storage chamber 511. When the adjusting plates 52 slide outwards from the seed storage chamber 511, a channel leading from the seed storage chamber 511 to the planting chamber 512 is exposed, allowing the seeds to fall into the planting chamber 512 through the channel. When the adjusting plates 52 slide inwards from the seed storage chamber 511, the channel leading from the seed storage chamber 511 to the planting chamber 512 is blocked, preventing the seeds from falling into the planting chamber 512. Through the sliding adjustment of multiple adjusting plates 52, the seeds can be positioned according to the user's requirements for planting. The seeding chamber 512 is divided into multiple sections at equal intervals by steel plates. Seeds falling into one section will not be pulled from the seeding scoop 56 into the bottom of the ridge from the seeding chamber 512 in other sections.

[0051] During operation, the power motor 57 provides power to the sowing structure 5. The power motor 57 drives the rotating shaft 54 ​​to rotate on the frame 3 through the mutual transmission between gears. The rotation of the rotating shaft 54 ​​drives the connecting gears 55 to rotate. The connecting gears 55 are in groups of three, with one fixedly installed on the rotating shaft 54 ​​and the other two rotatably installed on the support frame 53 on the side closer to the ground and the side farther from the ground. When the connecting gear 55 on the rotating shaft 54 ​​rotates, it transmits power to the other two connecting gears 55 in the same group through a chain. At this time, all the connecting gears 55 in the same group rotate simultaneously, driving the chain to move around the rotation direction of the connecting gears 55. During the movement of the chain, the lower seed scoop 56 moves along the movement trajectory of the chain. The movement of the lower seed scoop 56 carries the seeds in the sowing chamber 512 down the conveyor cylinder 59 into the seed furrow opened by the furrow opener 58.

[0052] Please see Figure 7 The frame 3 is equipped with a reinforcing block 10. One end of the reinforcing block 10 is fixedly installed on the frame 3, and the other end is fixedly installed on the conveyor cylinder 59. The reinforcing block 10 fixes the bottom of the conveyor cylinder 59 so that the bottom of the conveyor cylinder 59 can be more accurately aligned with the trencher 58, preventing the conveyor cylinder 59 from shifting due to vibration during the process.

[0053] Please see Figure 7 The pressing structure 6 includes a mounting frame 61 and a pressing roller 62. The mounting frame 61 is fixedly mounted on the machine frame 3. One end of the connecting rod 7 is mounted on the mounting frame 61. The pressing roller 62 is rotatably mounted on the mounting frame 61. The pressing roller 62 and the sowing structure 5 are driven by a chain.

[0054] During operation, the power is transmitted from the sowing structure 5 to the press roller 62 via a chain, causing the press roller 62 to rotate on the mounting frame 61, compacting the soil and ensuring close contact between the seeds and the soil to promote water absorption and germination. At the same time, it flattens the ridge surface, providing convenience for subsequent field management (such as irrigation and spraying).

[0055] Please see Figure 8 The tensioning structure 8 includes a first tensioning cylinder 811, a first tensioning rod 812, and a protrusion 813. A first tensioning rod 812 is installed at each end of the first tensioning cylinder 811. One end of the first tensioning rod 812 is threadedly connected to the first tensioning cylinder 811, and the other end is annular. One annular part of the first tensioning rod 812 is rotatably mounted on the rotary tillage structure 1, and the other annular part of the first tensioning rod 812 is rotatably mounted on the connecting rod 7. A protrusion 813 is installed on the first tensioning cylinder 811 to drive the first tensioning cylinder 811 to rotate.

[0056] Before starting work, select a suitable planting structure 5 according to the size of the garlic seeds to be planted. After fixing the lifting frame in the ridging structure 4 to the machine frame 3 with U-shaped screws, rotatably install one of the first tensioning rods 812 in the tensioning structure 8 onto the connecting rod 7. Rotate the other first tensioning rod 812 onto the rotary tillage structure 1. At this time, rotate the first tensioning cylinder 811. Since the first tensioning cylinder 811 is circular, a protrusion 813 is provided on the first tensioning cylinder 811 to facilitate the user's rotation using tools. The two ends of the first tensioning cylinder 811 are respectively connected to the two first tensioning rods 812 through threaded engagement. During the rotation of the first tensioning cylinder 811, the two first tensioning rods 812 will gradually be pulled towards each other. During the process of the first tensioning rods 812 being pulled closer, the connecting rod 7 and the rotary tillage structure 1 will be pulled towards each other simultaneously. During the movement, the fixing block 2 gradually aligns with the steel plate with multiple round holes on the rotary tillage structure 1. After complete alignment, the fixing block 2 is connected to the rotary tillage structure 1 using bolts, completing the assembly of the invention. The part of the connecting rod 7 extending out of the sowing structure 5 forms a triangle with the fixing block 2. The triangular stabilizing system effectively ensures the stability between components, while the modular design of the connecting structure allows the sowing structure 5 to be quickly replaced according to different garlic seed specifications.

[0057] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0058] In the first embodiment of the present invention:

[0059] Before operation, the fixing block 2 and the ridging structure 4 are installed on the frame 3 using U-shaped screws. A suitable sowing structure 5 is selected based on the size of the garlic seeds to be sown. One of the first tensioning rods 812 in the tensioning structure 8 is rotatably installed on the connecting rod 7. The other first tensioning rod 812 is rotatably installed on the rotary tillage structure 1. At this time, the first tensioning cylinder 811 is rotated. Since the first tensioning cylinder 811 is circular, a protrusion 813 is provided on it to facilitate rotation by the user using tools. Both ends of the first tensioning cylinder 811 are connected to the two first tensioning rods 812 via threaded engagement. During the rotation of the first tensioning cylinder 811, the two first tensioning rods 812 are gradually pulled towards each other. As the first tensioning rods 812 are pulled closer, they simultaneously pull the connecting rod 7 and the rotary tillage structure 1 towards each other. During the movement, the fixing block 2 gradually aligns with the steel plate with multiple round holes on the rotary tillage structure 1. After complete alignment, the fixing block 2 is connected to the rotary tillage structure 1 by bolts, thus completing the assembly of the present invention.

[0060] After assembly, garlic cloves are placed into the seed storage chamber 511 above the planting box 51. The position of the adjusting plates 52 on the seed storage chamber 511 is adjusted according to the required planting spacing. Multiple adjusting plates 52 are evenly distributed on the seed storage chamber 511. The adjusting plates 52 slide on the seed storage chamber 511. When the adjusting plates 52 slide outwards from the seed storage chamber 511, a channel from the seed storage chamber 511 to the planting chamber 512 is exposed, allowing the seeds to fall into the planting chamber 512 through the channel. When the adjusting plates 52 slide inwards from the seed storage chamber 511, the channel from the seed storage chamber 511 to the planting chamber 512 is blocked, preventing the seeds from falling into the planting chamber 512. Through the sliding adjustment of multiple adjusting plates 52, the seeds can be positioned according to the user's requirements for planting. The seeding chamber 512 is divided into multiple sections at equal intervals by steel plates. Seeds falling into one section will not be pulled from the seeding scoop 56 into the bottom of the ridge from the seeding chamber 512 in other sections.

[0061] During operation, the rear output shaft of the agricultural tractor's gearbox is connected to the first gearbox 13 in the rotary tiller structure 1. The agricultural tractor's gearbox provides power to the rotary tiller structure 1 and the ridging structure 4, driving the three output shafts of the first gearbox 13 to rotate simultaneously. The output shaft located above the first gearbox 13 is connected to the ridging structure 4 via a chain, providing power to the ridging structure 4. The other two output shafts located below the first gearbox 13 drive the rotary tiller blade shaft 14 to rotate within the rotary tiller housing 11. The rotation of the rotary tiller blade shaft 14 drives the rotary tiller blades 14 to rotate, simultaneously chopping up weeds and the roots of the previous crop. The rotary-tilled soil then enters the ridging structure's operating area. The second gearbox 42 of the ridging structure 4 is connected to the first gearbox 13 of the rotary tiller structure 1 via a chain, and the rotary tiller structure 1 transmits power to the ridging structure 4 via the chain. When the rotary tiller structure 1 is running, it drives the second gearbox 42 of the ridging structure 4 to run simultaneously. The two output ends of the second gearbox 42 rotate, causing the ridging shaft 43 to rotate on the ridging support 41. The rotation of the ridging shaft 43 drives the spiral blades 44 to rotate. The two spiral blades 44 rotate in opposite directions, gathering the loose soil after rotary tillage towards the center. The reverse spiral design pushes the soil on both sides towards the center and continuously piles up during the process to form a ridge.

[0062] In this invention, the power source for the sowing structure 5 and the pressing structure 6 is provided by the power motor 57 in the sowing structure 5. One end of the power motor 57 is connected to the rotating shaft 54 ​​via gear transmission, and the other end is connected to the pressing roller 62 via chain transmission.

[0063] The rotating shaft 54 ​​drives the connecting gears 55 to rotate. The connecting gears 55 are grouped in sets of three, with one fixedly mounted on the rotating shaft 54 ​​and the other two rotatably mounted on the support frame 53, one near the ground and the other away from the ground. When the connecting gear 55 on the rotating shaft 54 ​​rotates, it transmits power to the other two connecting gears 55 in the same group via a chain. At this time, all the connecting gears 55 in the same group rotate simultaneously, causing the chain to move around the rotation direction of the connecting gears 55. During this movement, the chain drives the seed scoop 56 to move along the chain's trajectory. The moving seed scoop 56 carries the seeds from the sowing chamber 512 down the conveyor cylinder 59 into the furrow opened by the furrow opener 58. The frame 3 is equipped with reinforcing blocks 10 to fix the bottom of the conveyor cylinder 59, ensuring more precise alignment of the bottom of the conveyor cylinder 59 with the furrow opener 58 and preventing the conveyor cylinder 59 from shifting due to vibration during operation.

[0064] Finally, the press roller 62 rotates on the mounting frame 61 to compact the soil, ensuring that the seeds are in close contact with the soil to promote water absorption and germination, while also leveling the ridge surface to facilitate subsequent field management (such as irrigation and spraying).

[0065] Second Embodiment

[0066] Please see Figures 9-11 In the second embodiment of the present invention:

[0067] The difference between the second embodiment and the first embodiment is that the tensioning structure 8 includes a second tensioning cylinder 821, a slider 822, an inclined block 823, a guide cavity 824, a trapezoidal block 825, a threaded rod 826, and a second tensioning rod 827. A slider 822 is slidably installed inside each of the two ends of the second tensioning cylinder 821, and an inclined block 823 is fixedly installed on each slider 822. Guide cavities 824 are formed at both ends of the second tensioning cylinder 821, and each guide cavity 824 is composed of the internal space of the second tensioning cylinder 821 and the internal spaces protruding at both ends of the second tensioning cylinder 821. The guide cavity 824 is rectangular in shape. The trapezoidal block 825 is slidably connected to the guide cavity 824. The inclined surface of the trapezoidal block 825 is slidably connected to the inclined surface of the inclined block 823. Two threaded rods 826 are rotatably installed at both ends of the second tensioning cylinder 821 and are connected to the trapezoidal block 825 by thread engagement. A second tensioning rod 827 is fixedly installed on the side of the slider 822 facing the end of the second tensioning cylinder 821. One end is fixedly installed on the slider 822, and the other end is composed of a safety hook. The safety hook part of one of the second tensioning rods 827 is installed on the rotary tillage structure 1, and the safety hook part of the other second tensioning rod 827 is installed on the connecting rod 7.

[0068] In the assembly of this invention, the safety hook portion of one of the second tensioning rods 821 in the tensioning structure 8 is installed on the connecting rod 7. The safety hook portion of the other second tensioning rod 821 is installed on the rotary tillage structure 1. At this time, the threaded rod 826 is rotated, and the cross-sectional shape of the second tensioning cylinder 821 is square. During the rotation of the threaded rod 826, the trapezoidal block 825 is driven to move within the guide cavity 824. During the movement of the trapezoidal block 825, the tilting block 823 is driven to move, and the movement of the tilting block 823 drives the slider 822 to move towards each other within the second tensioning cylinder 821. The movement of the slider 822 drives the second tensioning rod 827 to move, and during the process of the second tensioning rod 827 being pulled closer, it simultaneously pulls the connecting rod 7 and the rotary tillage structure 1 to move towards each other. During the movement, the fixing block 2 gradually aligns with the steel plate with multiple round holes on the rotary tillage structure 1. After complete alignment, the fixing block 2 is connected to the rotary tillage structure 1 by bolts, completing the assembly of this invention.
