[0012] A modular assembling method of an Artemisia selengensis sowing and tilling device, the assembling method comprising the following steps: When separating the tillage device, pull out the supporting connecting rods in the three trailers, and then loosen the limiting bolts in the row spacing adjustment assembly so that the limiting bolts will disengage from the limiting holes in the extension rods, that is, release the locking state between the sliding sleeve and the extension rod, and then push the frame under the connecting seat so that the frame drives the sliding sleeve to slide on the outside of the extension rod through the connecting seat until the sliding sleeve disengages from the extension rod. Similarly, operate the limiting bolts on the other side of the fixed seat to separate the frames on both sides from the middle frame, and then install walking wheels at one end of the spreading assemblies in the frames on both sides so that the three frames can move independently, and then loosen the bolts on both sides of the fixed seat and remove the two extension rods from both sides of the fixed seat, thus completing the disassembly work between multiple frames; When removing the tillage assembly from the bottom of the frame, loosen the fastening bolts to disengage them from the card holes, release the locking state between the column and the card seat, pull the plow blade downward to drive the column to slide in the card seat until the column slides off the card seat to remove the plow blade from the frame. When removing the bulldozer assembly and the cover plate, pull out the pin to disengage them from the frame and the plug hole, release the locking state of the bulldozer blade and the frame, pull the vertical rod downward to remove the bulldozer blade and the cover plate from the frame, and then lift the hopper upward to separate the bottom opening of the hopper from the middle of the spreading assembly, thereby completing the disassembly steps of the device; When assembling the device, the ends of the two extension rods are fixed to the two sides of the fixing seat by bolts, and then the walking wheels of the spreading components in the frames on both sides close to the middle frame are removed, and the frames on both sides are moved to drive the sliding sleeves to be sleeved on the outside of the extension rods. The sliding sleeves are supported and limited by the extension rods with a rectangular cross-section, thereby improving the stability of the horizontal movement of the frames on both sides and making all the frames on the same horizontal line. Since there are several limiting holes in the extension rods, the limiting bolts can be stuck in any limiting hole to adjust and lock the position of the sliding sleeve, the connecting seat and the frame, so as to adjust the distance between the two adjacent frames. At the same time, the soil turning components at the bottom of multiple frames The spacing between them changes, so as to freely adjust the row spacing of Qi Ai planting. After the frames on both sides and the middle frame are assembled, the columns in the multiple soil-turning assemblies are inserted into the interior of the card seat in turn. After adjusting the height of the plow blade, the fastening bolt is inserted into one of the card holes to lock the column and the plow blade. Secondly, the vertical rod in the bulldozer assembly is inserted into one side of the frame. After adjusting the position of the bulldozer blade and the covering plate, the pin is inserted into one of the sockets from one side of the frame to achieve the purpose of locking the height of the bulldozer blade and the covering plate. The silo is set in the frame so that the middle part of the spreading assembly is located in the opening at the bottom of the silo, thereby completing the assembly of the device; When in use, insert the supporting connecting rod into the through-holes on the top of the three trailers, then pour the crushed mugwort roots or seeds into multiple silos, and connect the two ends of the supporting connecting rod to the external tractor trailer. During the driving process, the tractor trailer drives the three frames to move synchronously through the supporting connecting rod and multiple trailers, so that the walking wheels roll on the ground, and at the same time, the plow blades at the bottom of the frames open grooves in the land, and the walking wheels drive the rotating shaft to rotate inside the bearing seat, and the rotating shaft is supported and limited by the bearing seat, so as to improve the stability of the rotating shaft driving the two baffles and multiple material-digging plates to rotate. When the hopper is rotated counterclockwise, the rotating shaft drives the baffle and the diverter plate to rotate in the opposite direction. The diverter plate flips up the mugwort roots or mugwort seeds at the bottom opening of the hopper, and cooperates with the two baffles to block the mugwort roots or mugwort seeds, preventing the mugwort roots or mugwort seeds from falling into the designated area and being spread off-center. As the diverter plate continues to rotate, the mugwort roots or mugwort seeds are guided into the groove to achieve the purpose of automatic directional sowing. As the frame continues to move forward, the two bulldozers behind the coulter push the soil on both sides of the groove into the groove, and cooperate with the use of two covering plates to cover the soil on top of the mugwort roots or mugwort seeds to complete the sowing of mugwort. When adjusting the width of the covering plate, the screw rod is driven to rotate by turning the handle. During the rotation of the screw rod, the nut drives the slide to move inside the retaining frame, and the rectangular slide is limited by the inner wall of the retaining frame to improve the stability of the horizontal movement of the slide. The slide pushes or pulls the two covering plates on both sides of the bulldozer through two connecting rods and two support rods. Since the rotating rod on one side of the covering plate is sleeved and rotated in the shaft sleeve on one side of the bulldozer, the stability of the deflection of the covering plate is improved, and the covering width can be flexibly adjusted by adjusting the angle of the covering plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The cam is fixed on the upper and lower ends of the support frame by bolts, and the travel wheels of the spreading assembly on the two side frames are removed near the middle frame. The frames on both sides are moved to drive the sliding sleeves to be sleeved on the outside of the extension rods. The extension rods with a rectangular cross-section are used to support and limit the sliding sleeves, thereby improving the stability of the horizontal movement of the frames on both sides and making all frames on the same horizontal line. Since a plurality of limiting holes are provided in the extension rods, the limiting bolts can be stuck in any limiting hole to adjust and lock the positions of the sliding sleeves, the connecting seat and the frames. By adjusting the distance between the two adjacent frames, at the same time, the spacing between the soil turning assemblies at the bottom of the multiple frames is changed, so as to freely adjust the row spacing of the wormwood planting, and the frames on both sides and the frame assembly in the middle can be connected. After the installation is completed, the columns of the multiple soil-turning components are inserted into the inside of the card seat in turn, and the fastening bolt is inserted into one of the card holes after adjusting the height of the plow blade to lock the column and the plow blade. Secondly, the vertical rod of the bulldozer assembly is inserted into one side of the frame, and the position of the bulldozer and the covering plate is adjusted, and the pin is inserted into one of the sockets from one side of the frame to achieve the purpose of locking the height of the bulldozer and the covering plate. The silo is set in the frame so that the middle of the spreading component is located in the opening at the bottom of the silo to complete the assembly of the device. Therefore, the function of the device can be quickly adjusted by replacing or adding or removing modules. The function expansion is easy, and the modular design can realize the flexible combination and splitting of the device functions, the transportation difficulty is low, and it can adapt to the needs of different operation scenarios and planting scales. 2. The present invention digs grooves in the land through the plow blade at the bottom of the frame, and the walking wheel drives the rotating shaft to rotate inside the bearing seat, and the rotating shaft is supported and limited by the bearing seat, thereby improving the stability of the rotating shaft driving the two baffles and multiple stripping plates to rotate. Since the walking wheel rotates counterclockwise when moving forward, the rotating shaft drives the baffles and the stripping plate to rotate in the opposite direction, and the stripping plate flips up the mugwort roots or mugwort seeds at the bottom opening of the silo, and cooperates with the two baffles to block the mugwort roots or mugwort seeds, preventing the mugwort roots or mugwort seeds from falling into the designated area and being spread off-center. As the stripping plate continues to rotate, the mugwort roots or mugwort seeds are guided into the groove, thereby realizing the purpose of automatic directional sowing. As the frame continues to move forward, the rear of the plow blade The two bulldozers push the soil on both sides of the trench into the trench, and with the use of two covering plates, the soil is covered on top of the mugwort roots or seeds to achieve the purpose of automatic sowing of mugwort. Secondly, the slide pushes or pulls the two covering plates on both sides of the bulldozer through two connecting rods and two support rods to deflect. The covering width can be flexibly adjusted by adjusting the angle of the covering plate. Widening the width can cover a larger area of ​​the surface, reduce soil moisture evaporation, keep the soil around the roots moist, and prevent seedlings from drying out due to lack of water. Reducing the covering width can reduce soil compaction, increase the contact area between the surface and the air, which is beneficial to root breathing and avoids soil compaction and root hypoxia caused by excessive covering.

During the driving process, the traction trailer drives the three frames 2 to move synchronously through the supporting link 4 and multiple trailers 3, so that the walking wheels 6 roll on the ground. At the same time, the plow 802 at the bottom of the frame 2 digs grooves in the land, and the walking wheels 6 drive the rotating shaft 501 to rotate inside the bearing seat 502. The rotating shaft 501 is supported and limited by the bearing seat 502, thereby improving the stability of the rotating shaft 501 driving the two baffles 503 and multiple diverter plates 504 to rotate. When the wheel 6 moves forward, it rotates counterclockwise, so that the rotating shaft 501 drives the baffle 503 and the material-diverting plate 504 to rotate in the opposite direction. The material-diverting plate 504 flips up the mugwort root or mugwort seeds at the bottom opening of the hopper 1, and cooperates with the two baffles 503 to block the mugwort root or mugwort seeds from entering, preventing the mugwort root or mugwort seeds from falling into the designated area and being spread sideways. As the material-diverting plate 504 continues to rotate, the mugwort root or mugwort seeds are guided into the groove, thereby achieving the purpose of automatic directional sowing. As the frame 2 continues to move forward, the two bulldozers 102 behind the coulter 802 push the soil on both sides of the groove into the groove, and cooperate with the use of the two covering plates 11 to cover the soil above the mugwort root or mugwort seeds to complete the sowing of mugwort. When adjusting the width of the covering plate 11, the screw rod 122 is driven to rotate by turning the handle 127. During the rotation of the screw rod 122, the nut 123 drives the slide 124 to move inside the baffle 121. The rectangular slide 124 is limited by the inner wall of the baffle 121 to improve the stability of the horizontal movement of the slide 124. The slide 124 pushes or pulls the two covering plates 11 on both sides of the bulldozer 102 through two connecting rods 125 and two support rods 126. Since the rotating rod on one side of the covering plate 11 is sleeved and rotated in the shaft sleeve on one side of the bulldozer 102, the stability of the deflection of the covering plate 11 is improved, and the covering width can be flexibly adjusted by adjusting the angle of the covering plate 11.

The sleeve (705) is separated from the extension rod (702). Similarly, the limiting bolt (707) on the other side of the fixed seat (701) is operated to separate the racks (2) on both sides from the rack (2) in the middle. Then, the walking wheel (6) is installed at one end of the spreading assembly (5) in the racks (2) on both sides so that the three racks (2) can be transferred independently. Then, the bolts (703) on both sides of the fixed seat (701) are loosened and the two extension rods (702) are removed from both sides of the fixed seat (701). Thus, the disassembly work between the multiple racks (2) is completed. When removing the tiller assembly (8) from the bottom of the frame (2), loosen the fastening bolt (804) to disengage it from the card hole (805), release the locking state between the column (801) and the card seat (803), pull the plow blade (802) downward to drive the column (801) to slide in the card seat (803), until the column (801) slides off the card seat (803) and remove the plow blade (802) from the frame (2), and then remove the bulldozer assembly (10) and When the covering plate (11) is removed, the latch (104) is pulled out to separate it from the frame (2) and the socket (103), the locking state between the bulldozer (102) and the frame (2) is released, and the vertical rod (101) is pulled downward to remove the bulldozer (102) and the covering plate (11) from the frame (2), and then the silo (1) is lifted upward to separate the bottom opening of the silo (1) from the middle of the spreading assembly (5), thereby completing the disassembly steps of the device; When assembling the device, the ends of the two extension rods (702) are fixedly mounted on both sides of the fixing seat (701) by means of bolts (703). Then, the walking wheels (6) of the spreading components (5) close to the middle frame (2) in the racks (2) on both sides are removed. The racks (2) on both sides are moved so as to drive the sliding sleeve (705) to be sleeved on the outside of the extension rods (702). The sliding sleeve (705) is supported and limited by the extension rods (702) with a rectangular cross-section, thereby increasing the height of the two racks. The stability of the horizontal movement of the side frame (2) makes all the frames (2) on the same horizontal line. Since the extension rod (702) is provided with a plurality of limiting holes (704), the limiting bolt (707) can be inserted into any limiting hole (704) to adjust and lock the position of the sliding sleeve (705), the connecting seat (706) and the frame (2), thereby adjusting the distance between two adjacent frames (2). At the same time, the soil turning components (8) at the bottom of multiple frames (2) are connected. The spacing between the rows is changed so as to freely adjust the row spacing of the Ai Ai planting. After the racks (2) on both sides are assembled with the rack (2) in the middle, the columns (801) in the plurality of soil turning components (8) are sequentially inserted into the interior of the card seat (803). After adjusting the height of the plow (802), the fastening bolt (804) is inserted into one of the card holes (805) to lock the column (801) and the plow (802). Then, the vertical column (801) in the bulldozer component (10) is inserted into the card seat (803). The rod (101) is inserted through one side of the frame (2), and after adjusting the positions of the bulldozer (102) and the covering plate (11), the pin (104) is inserted into one of the sockets (103) from one side of the frame (2) to achieve the purpose of locking the bulldozer (102) and the covering plate (11) at a high level. The silo (1) is set up in the frame (2) so that the middle of the spreading assembly (5) is located in the opening at the bottom of the silo (1), thereby completing the assembly of the device; When in use, the supporting connecting rod (4) is inserted into the through hole (9) at the top of the three trailers (3), and then the crushed mugwort roots or mugwort seeds are poured into the multiple silos (1). The two ends of the supporting connecting rod (4) are connected to the external traction trailer. During the driving process, the traction trailer drives the three frames (2) to move synchronously through the supporting connecting rod (4) and the multiple trailers (3), so that the walking wheel (6) rolls on the ground. At the same time, the plow blade (802) at the bottom of the frame (2) opens a groove on the land, and the walking wheel (6) drives the rotating shaft (501) to rotate inside the bearing seat (502). The rotating shaft (501) is supported and limited by the bearing seat (502), thereby improving the stability of the rotating shaft (501) driving the two baffles (503) and the multiple diverter plates (504) to rotate. Qualitatively, as the walking wheel (6) rotates counterclockwise when moving forward, the rotating shaft (501) drives the baffle (503) and the material-diverting plate (504) to rotate in the opposite direction, and the material-diverting plate (504) flips the mugwort root or mugwort seed at the bottom opening of the hopper (1) upward, and cooperates with the two baffles (503) to block the mugwort root or mugwort seed, preventing the mugwort root or mugwort seed from falling into the designated area and being scattered. As the material-diverting plate (504) continues to rotate, the mugwort root or mugwort seed is guided into the groove, thereby achieving the purpose of automatic directional sowing. As the frame (2) continues to move forward, the two bulldozers (102) behind the plow (802) push the soil on both sides of the groove into the groove, and cooperate with the use of the two covering plates (11) to cover the soil above the mugwort root or mugwort seed, thereby completing the sowing of mugwort. When the width of the covering plate (11) is adjusted, the screw rod (122) is driven to rotate by rotating the handle (127). During the rotation of the screw rod (122), the nut (123) drives the slide (124) to move inside the retaining frame (121). The rectangular slide (124) is limited by the inner wall of the retaining frame (121) to improve the stability of the horizontal movement of the slide (124). The slide (124) pushes or pulls the two covering plates (11) to deflect on both sides of the bulldozer (102) through two connecting rods (125) and two supporting rods (126). Since the rotating rod on one side of the covering plate (11) is sleeved and rotated in the shaft sleeve on one side of the bulldozer (102), the stability of the deflection of the covering plate (11) is improved, and the covering width is flexibly adjusted by adjusting the angle of the covering plate (11).
