Description

Technical Field

[0001] This invention relates to the field of soil cultivation technology, and in particular to an intelligent soil cultivation device and its usage method for soybean production. Background Technology

[0002] Hilling is a process that, after planting crops, involves turning over the soil between crops and covering the roots with the turned-up soil, combined with weeding. Hilling thickens the soil layer, providing deeper soil space for root growth, and also covers fertilizer. Covering the fertilizer with soil reduces its volatilization and loss; furthermore, the fertilizer decomposes slowly in the soil, continuously providing nutrients to the crops. However, several problems can easily arise during hilling:

[0003] First, it is necessary to ensure that the roots and seedlings are not damaged during the soil mounding process. This requires corresponding protection of the planted crop during the soil mounding process. If the planted crop is not protected, it will be damaged, and in severe cases, it will lead to the death of the crop. At the same time, it is also necessary to avoid damaging the roots of the crop during the soil mounding process.

[0004] Secondly, the fertilizer used for covering during the soil mounding process needs to decompose slowly. However, the existing fertilizer covering technology involves burying large pieces of fertilizer in the soil to cover the fertilizer. However, the decomposition of this fertilizer usually occurs in the same layer, which does not achieve the effect of slow decomposition. It should be mixed with the soil before being put into the soil.

[0005] To this end, we designed an intelligent soil-raising device for soybean production and planting, as well as its usage method. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that the fertilizer covered during the soil covering process needs to decompose slowly. However, the existing fertilizer covering technology involves burying large pieces of fertilizer in the soil to achieve fertilizer burial. However, the decomposition of this fertilizer usually occurs in the same layer, which fails to achieve the effect of slow decomposition. Therefore, this invention proposes an intelligent soil covering device and method for soybean production and planting.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A smart hilling device for soybean production includes a main beam and an end cylinder at the end of the main beam. Two symmetrically swinging side frames are located on both sides of the end cylinder. A first sliding frame slides on the main beam, and the side swinging frames are connected to the first sliding frame via a connecting rod assembly. The side swinging frames are connected to the end cylinder via a lifting part. Each of the two side swinging frames has a third sliding frame, and a support is rotatably mounted at the bottom of the third sliding frame. A second sliding frame slides on the main beam, and a first telescopic rod assembly connects the second sliding frame to the support. The support has a soil-scraping part for soil scraping. A liquid storage cylinder is located below the second sliding frame, and a second telescopic rod assembly is located between the second sliding frame and the liquid storage cylinder. A drive ring for driving the soil-scraping part to rotate is symmetrically fitted on the outer wall of the liquid storage cylinder. A telescopic cylinder connected to the soil-scraping part slides symmetrically on the liquid storage cylinder. A linkage ring fixed to the soil-scraping part is coaxially fitted on the telescopic cylinder, and a rubber hose for introducing fertilizer solution into the soil-scraping part is provided on the linkage ring.

[0009] Preferably, the connecting rod assembly includes a connecting rod and two shaft assembly assemblies. One end of the connecting rod is rotatably connected to the side swing frame through the shaft assembly, and the other end of the connecting rod is raised and lowered and slidably connected to the first sliding frame through the shaft assembly.

[0010] Preferably, two rotating grooves are symmetrically formed on the side wall of the end cylinder, and a rotating shaft platform swings within the rotating groove. A drive screw is provided between the two rotating shaft platforms on the same side, and the drive screw is connected to the side swing frame.

[0011] Preferably, the excavating section includes:

[0012] A mixing chamber, wherein multiple mixing chambers are arranged in a circular pattern, and the multiple mixing chambers are fixed in a circular pattern on a linkage ring, the linkage ring being connected to a drive ring via a thin rod;

[0013] A soil-breaking blade is provided on one side of the mixing box, with the opening of the mixing box facing the soil-breaking blade. The opening of the mixing box is provided with a soil-blocking plate, and a side plate is provided on one side of the soil-blocking plate. A first return spring is provided between the side plate and the mixing box.

[0014] Preferably, the telescopic cylinder is fixed with an end post, and the outer side wall of the end post is symmetrically provided with side grooves, and the two side grooves are horizontally arranged. The side plate abuts against the outer side wall of the end post through a first reset spring. The side groove includes an inner groove, and both sides of the inner groove are chamfered.

[0015] Preferably, the retaining plate includes a retaining slide plate and a retaining flap plate. The retaining slide plate slides in the opening of the mixing box, and the retaining flap plate rotates with the retaining slide plate via a rotating shaft. A fourth return spring is connected between the retaining slide plate and the retaining flap plate, and the retaining slide plate is provided with a positioning part for positioning the rotating shaft.

[0016] Preferably, the positioning part includes:

[0017] The insert rod has a sliding cavity inside the retaining plate, and the insert rod slides and extends within the sliding cavity. The rotating shaft has a insertion hole that is compatible with the insert rod.

[0018] Preferably, a magnet is provided in the side groove, and an iron block is fixed to the side of the insertion rod facing the end post. A first retaining ring and a second retaining ring are fixed to the inner wall of the sliding cavity, and the iron block is located between the first retaining ring and the second retaining ring. A third return spring is provided between the iron block and the second retaining ring.

[0019] Preferably, the mixing chamber is provided with multiple extending stirring shafts, and a driven gear is coaxially fixed on the outer wall of the stirring shaft. The side wall of the mixing chamber is provided with a drive gear driven by an external driving device, and the drive gear meshes with the driven gear. The outer wall of the stirring shaft is provided with multiple fertilizer outlet holes and spiral blades for stirring. The rubber hose is connected to the fertilizer outlet holes.

[0020] The specific steps for using an intelligent hilling device for soybean production and planting are as follows:

[0021] S1: First, adjust the position of the first sliding frame on the main beam according to the spacing between two adjacent soybean seedlings. Then, fix the first sliding frame on the main beam by spiral positioning. At this time, the side swing frames on both sides of the main beam will control the opening angle according to the adjustment. This can achieve the effect of not damaging the soybean seedlings. The soil-building operation is only applied to the soil between two adjacent soybean seedlings, thus completing the soil-building between them. Since the soil-digging part is located at the bottom of the third sliding frame on the side swing frame, and due to the presence of the first telescopic rod assembly, the first telescopic rod assembly and the soil-digging part are set perpendicular to each other and the first telescopic rod assembly is perpendicular to the main beam. This makes the rotation direction of the soil-digging part at the bottom of the third sliding frame always face the forward direction of the main beam. No matter how large or small the opening angle of the side swing frame is, the soil-digging part is located on one side of the soybean seedling roots, without damaging the soybean seedling roots. At the same time, it can also ensure that the soil around the soybean seedlings is in a soil-building state, and the soil containing fertilizer is located around the soybean seedling roots, which is convenient for the soybean seedlings to absorb better.

[0022] S2: By turning on the external drive motor, the drive screw on the rotating shaft table is rotated. The threaded hole on the side swing frame is matched with the drive screw, which will drive the side swing frame to slide up and down on both sides of the end cylinder, thereby driving the soil-digging part on the side swing frame to rise and fall, thereby controlling the depth of the soil-digging part into the soil, thus realizing the expansion of the soil-covering depth.

[0023] S3: The drive ring symmetrically sleeved on the outer wall of the liquid storage tank is driven to rotate by an external drive device, and drives the linkage ring and multiple mixing boxes on the linkage ring to rotate together through a thin rod. One side of the mixing box is equipped with a U-shaped soil-breaking blade, so that the linkage ring drives the soil-breaking blade on the mixing box to rotate and dig soil.

[0024] As the rotation continues and the mixing chamber opening faces vertically upward, the retaining plate that was originally against the outer wall of the end column will retract into the side groove located horizontally on the end column under the action of the first return spring. In this way, the retaining plate that was originally blocking the opening of the mixing chamber will open. At the same time, due to the insertion rod installed in the retaining plate, as the retaining plate extends into the inner groove, the iron block at the end of the insertion rod will be attracted by the magnet in the inner groove, thereby causing the insertion rod that was originally stuck in the insertion hole on the rotating shaft to be pulled out, thereby releasing the rotation limit of the retaining flap on the retaining plate. The soil that was originally piled up at the soil breaking edge will be pushed and flipped by gravity, allowing this part of the soil to fall into the mixing chamber.

[0025] S4: The liquid storage tank is connected to the external fertilizer tank, and liquid fertilizer is added to the liquid storage tank. As the rotation continues, due to the fourth return spring connecting the soil retaining plate and the soil retaining flap, and without the pressure of soil, the soil retaining plate and the soil retaining flap will return to a flush state under the action of the fourth return spring. The soil retaining plate, which was originally located in the side groove, is pushed out again. The iron block is no longer attracted by the magnetic piece, but is reset to the insertion hole on the rotating shaft under the action of the third return spring, and the rotation limit of the soil retaining flap is achieved in the soil retaining plate. Since the linkage ring has an inner cavity, and the inner cavity is connected to the telescopic cylinder, the liquid fertilizer in the liquid storage tank will enter the linkage ring through the telescopic cylinder, and then enter the mixing shaft through the rubber hose. The rubber hose is rotatably connected to the mixing shaft through the rotating cap, and is discharged from the fertilizer outlet hole on the mixing shaft. Then the drive gear drives the driven gear to rotate the mixing shaft, completing the mixing of liquid fertilizer and soil.

[0026] S5: As the rotation continues, when the opening of the mixing box containing the soil and fertilizer mixture is vertically downward, the retaining plate that abuts against the outer wall of the end column will retract back into the side groove located horizontally on the end column under the action of the first return spring. Repeat the above operation. At this time, the retaining plate flips in the opposite direction under the action of the soil, allowing the soil to be poured out of the mixing box. As the rotation continues, the retaining plate will cover the opening of the mixing box again, thus forming the function of digging, mixing, and refilling soil.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention activates an external drive motor, which drives the drive screw on the rotating shaft to rotate. The threaded hole on the side swing frame is adapted to the drive screw, which causes the side swing frame to slide up and down on both sides of the end cylinder. This, in turn, causes the soil-digging part on the side swing frame to rise and fall, thereby controlling the depth of the soil-digging part into the soil and thus increasing the depth of soil covering.

[0029] 2. This invention employs a soil-digging section and a soil-retaining flap that flips in both forward and reverse directions under the action of the soil. Liquid fertilizer is discharged from the fertilizer outlet on the mixing shaft. Then, the drive gear drives the driven gear to rotate the mixing shaft, completing the mixing of the liquid fertilizer and soil. The soil is then poured into and out of the mixing box. As the rotation continues, the soil-retaining flap will cover the opening of the mixing box again, thus forming the functions of digging, mixing, and refilling soil. Attached Figure Description

[0046] Reference Figures 1-9 A smart hilling device for soybean production includes a main beam 1 and an end cylinder 3 located at the end of the main beam 1. The end cylinder 3 has two symmetrically swinging side swing frames 2 on both sides. The side wall of the end cylinder 3 has two symmetrically opened rotating grooves 6, and a rotating shaft platform 4 swings in the rotating grooves 6. The position of the first sliding frame 7 located on the main beam 1 is adjusted according to the distance between two adjacent soybean seedlings. Then, the first sliding frame 7 is fixed on the main beam 1 by a screw positioning. At this time, the side swing frames 2 on both sides of the main beam 1 will open at an angle controlled according to the adjustment. This can achieve the effect of not damaging the soybean seedlings and the hilling operation is only applied to the soil between two adjacent soybean seedlings, thereby completing the hilling of the soil between them.

[0047] Since the soil-digging part 18 is located at the bottom of the third sliding frame 9 on the side swing frame 2, and due to the presence of the first telescopic rod assembly 10, the first telescopic rod assembly 10 and the soil-digging part 18 are set perpendicular to each other, and the first telescopic rod assembly 10 is perpendicular to the main beam 1, thus the rotation direction of the soil-digging part 18 at the bottom of the third sliding frame 9 is always in the forward direction of the main beam 1. No matter how large or small the opening angle of the side swing frame 2 is, the soil-digging part 18 is located on one side of the soybean seedling root, and will not damage the soybean seedling root. At the same time, it can also ensure that the soil around the soybean seedling is in a mound state, and the soil containing fertilizer is located around the soybean seedling root, which is convenient for the soybean seedling to absorb better.

[0048] The side swing frame 2 is connected to the end cylinder 3 via a lifting part. A first sliding frame 7 slides on the main beam 1, and the side swing frame 2 is connected to the first sliding frame 7 via a connecting rod assembly 11. The connecting rod assembly 11 includes a connecting rod and two shaft assembly assemblies. One end of the connecting rod is rotatably connected to the side swing frame 2 via the shaft assembly, and the other end of the connecting rod is raised and lowered and slidably connected to the first sliding frame 7 via the shaft assembly. A drive screw 5 is provided between the two rotating shaft assemblies 4 on the same side, and the drive screw 5 is connected to the side swing frame 2. In this way, by turning on the external drive motor, the drive screw 5 on the rotating shaft assemblies 4 is driven to rotate. The threaded hole opened on the side swing frame 2 is adapted to the drive screw 5, which will drive the side swing frame 2 to rise and fall and slide on both sides of the end cylinder 3, thereby driving the digging part 18 on the side swing frame 2 to rise and fall, thereby controlling the depth of the digging part 18 penetrating the soil, thereby realizing the expansion of the soil covering depth.

[0049] Both side swing frames 2 are equipped with a third sliding frame 9, and the bottom of the third sliding frame 9 is rotatably supported by a bracket 17. A second sliding frame 8 slides on the main beam 1, and a first telescopic rod assembly 10 is connected between the second sliding frame 8 and the bracket 17.

[0050] Reference Figure 3 and Figure 4 In the above-mentioned state, the support 17 is provided with a soil-scraping part 18 for soil scraping. The soil-scraping part 18 includes a mixing box 181, which is arranged in a circle. The multiple mixing boxes 181 are fixed in a circle on the linkage ring 16. A liquid storage cylinder 13 is provided below the second sliding frame 8. A second telescopic rod assembly 12 is provided between the second sliding frame 8 and the liquid storage cylinder 13. A drive ring 14 for driving the soil-scraping part 18 to rotate is symmetrically sleeved on the outer wall of the liquid storage cylinder 13. The linkage ring 16 is connected to the drive ring 14 through a thin rod. The drive ring 14 symmetrically sleeved on the outer wall of the liquid storage cylinder 13 is driven to rotate by an external drive device, and drives the linkage ring 16 and the multiple mixing boxes 181 on the linkage ring 16 to rotate together through the thin rod.

[0051] The excavating section 18 also includes a soil-breaking blade 182, which is located on one side of the mixing box 181 and the opening of the mixing box 181 faces the soil-breaking blade 182. The soil-breaking blade 182 is U-shaped on one side of the mixing box 181, so that the soil-breaking blade 182 on the mixing box 181 can rotate and excavate soil when driven by the linkage ring 16.

[0052] The opening of the mixing box 181 is provided with a retaining plate 183 to block the opening. A side plate 184 is provided on one side of the retaining plate 183, and a first reset spring 185 is provided between the side plate 184 and the mixing box 181. This makes the retaining plate 183 abut against the outer wall of the end column 19 under the action of the first reset spring 185.

[0053] The retaining plate 183 includes a retaining slide plate 1831 and a retaining flap 1832. The retaining slide plate 1831 slides in the opening of the mixing box 181. The retaining flap 1832 rotates with the retaining slide plate 1831 via a rotating shaft 27. A fourth return spring is connected between the retaining slide plate 1831 and the retaining flap 1832. The retaining slide plate 1831 is provided with a positioning part for positioning the rotating shaft 27.

[0054] The positioning part includes a rod 29, a sliding cavity 26 is provided in the retaining plate 1831, and the rod 29 slides in the sliding cavity 26. A hole 28 is provided on the rotating shaft 27, and the hole 28 is adapted to the rod 29.

[0055] The liquid storage cylinder 13 has a telescopic cylinder 15 that slides symmetrically with the soil excavation part 18. The end of the telescopic cylinder 15 is fixed with an end post 19. The outer side wall of the end post 19 is symmetrically provided with side grooves 20, and the two side grooves 20 are horizontally arranged.

[0056] As the rotation continues and the opening of the mixing box 181 faces vertically upward, the retaining plate 183, which was originally abutting against the outer wall of the end column 19, will retract into the side groove 20 located horizontally on the end column 19 under the action of the first return spring 185. In this way, the retaining plate 183, which was originally blocking the opening of the mixing box 181, will open, and at the same time, due to the insertion rod 29 provided in the retaining plate 1831.

[0057] A magnet 25 is provided in the side groove 20, and an iron block 32 is fixed on the side of the insertion rod 29 facing the end post 19. A first retaining ring 30 and a second retaining ring 31 are fixed on the inner wall of the sliding cavity 26 respectively, and the iron block 32 is located between the first retaining ring 30 and the second retaining ring 31. A third return spring 33 is provided between the iron block 32 and the second retaining ring 31.

[0058] As the retaining plate 1831 extends into the built-in groove 201, the iron block 32 at the end of its insert rod 29 is attracted by the magnet 25 located in the built-in groove 201, thereby causing the insert rod 29, which was originally stuck in the insertion hole 28 on the rotating shaft 27, to be pulled out. This releases the rotation limit of the retaining flap 1832 on the retaining plate 1831, and the soil that was originally piled up at the soil breaking blade 182 will be pushed by gravity to flip the retaining flap 1832 and let this part of the soil fall into the mixing box 181.

[0059] A linkage ring 16, which is fixed to the soil-digging part 18, is coaxially sleeved on the telescopic cylinder 15. The linkage ring 16 is equipped with a rubber hose 21 for introducing fertilizer liquid into the soil-digging part 18. Multiple stirring shafts 22 are inserted into the mixing box 181. A driven gear 23 is coaxially fixed on the outer wall of the stirring shaft 22. A drive gear 24 driven by an external drive device is provided on the side wall of the mixing box 181. The drive gear 24 meshes with the driven gear 23. Multiple fertilizer outlet holes 34 and spiral blades for stirring are provided on the outer wall of the stirring shaft 22. The rubber hose 21 is connected to the fertilizer outlet holes 34. The liquid storage cylinder 13 is connected to the external fertilizer tank and liquid fertilizer is added into the liquid storage cylinder 13. As the rotation continues, since a fourth return spring is connected between the soil-retaining slide plate 1831 and the soil-retaining flap 1832, and there is no soil pressure, the soil-retaining slide plate 1831 and the soil-retaining flap 1832 will return to a flush state under the action of the fourth return spring.

[0060] The side plate 184 abuts against the outer wall of the end post 19 via the first return spring 185. The side groove 20 includes an inner groove 201, and chamfers 202 are provided on both sides of the inner groove 201. This facilitates the repulsion plate 1831, which was originally located in the side groove 20, to be pushed out again. The iron block 32 is no longer attracted by the magnet 25, but is reset to the insertion hole 28 on the rotating shaft 27 under the action of the third return spring 33, and the rotation limit of the repulsion flap 1832 in the repulsion plate 1831 is realized.

[0061] Since the linkage ring 16 has an inner cavity that is connected to the telescopic cylinder 15, the liquid fertilizer in the storage tank 13 will enter the linkage ring 16 through the telescopic cylinder 15, and then enter the stirring shaft 22 through the rubber hose 21. The rubber hose 21 is rotatably connected to the stirring shaft 22 through a rotating cap, and is discharged from the fertilizer outlet 34 on the stirring shaft 22. Then, the drive gear 24 drives the driven gear 23 to rotate the stirring shaft 22, thus completing the mixing of the liquid fertilizer and the soil.

[0062] As the rotation continues, when the opening of the mixing box 181 containing the mixture of soil and fertilizer is vertically downward, the retaining plate 183, which abuts against the outer wall of the end column 19, will retract back into the side groove 20 located horizontally on the end column 19 under the action of the first return spring 185. The above operation is repeated. At this time, the retaining flap 1832 flips in the opposite direction under the action of the soil, allowing the soil to be poured out of the mixing box 181. As the rotation continues, the retaining plate 183 will cover the opening of the mixing box 181 again, thus forming the function of digging, mixing, and refilling soil.

[0063] The working principle of this invention is as follows:

[0064] S1: First, adjust the position of the first sliding frame 7 on the main beam 1 according to the spacing between two adjacent soybean seedlings. Then, fix the first sliding frame 7 on the main beam 1 using a spiral positioning mechanism. At this time, the side swing frames 2 on both sides of the main beam 1 will open at an angle controlled by the adjustment. This ensures that the soybean seedlings are not damaged, and the soil-covering operation is only applied to the soil between two adjacent soybean seedlings, thus completing the soil-covering process. Since the digging part 18 is located at the bottom of the third sliding frame 9 on the side swing frame 2, and due to the first telescopic... With the presence of the rod assembly 10, the first telescopic rod assembly 10 and the soil-digging part 18 are set perpendicular to each other, and the first telescopic rod assembly 10 is perpendicular to the main beam 1. This ensures that the rotation direction of the soil-digging part 18 at the bottom of the third sliding frame 9 is always in the forward direction of the main beam 1. Regardless of the opening angle of the side swing frame 2, the soil-digging part 18 is located on one side of the soybean seedling root, without damaging the soybean seedling root. At the same time, it ensures that the soil around the soybean seedling is in a mounded state, and the soil containing fertilizer is located around the soybean seedling root, which is convenient for the soybean seedling to absorb better.

[0065] S2: By turning on the external drive motor, the drive screw 5 on the rotating shaft 4 is driven to rotate. The threaded hole on the side swing frame 2 is adapted to the drive screw 5, which will drive the side swing frame 2 to slide up and down on both sides of the end cylinder 3, thereby driving the soil-digging part 18 on the side swing frame 2 to rise and fall, thereby controlling the depth of the soil-digging part 18 into the soil, thus realizing the expansion of the soil-covering depth.

[0066] S3: The drive ring 14 symmetrically sleeved on the outer wall of the liquid storage tank 13 is driven to rotate by the external drive device, and drives the linkage ring 16 and the multiple mixing boxes 181 on the linkage ring 16 to rotate together through the thin rod. The mixing box 181 is provided with a U-shaped soil breaking blade 182 on one side, so that the linkage ring 16 drives the soil breaking blade 182 on the mixing box 181 to rotate and dig soil.

[0067] As the rotation continues and the opening of the mixing box 181 faces vertically upward, the retaining plate 183, which was originally abutting against the outer wall of the end post 19, will retract into the side groove 20 located horizontally on the end post 19 under the action of the first return spring 185. In this way, the retaining plate 183, which was originally blocking the opening of the mixing box 181, will open. At the same time, due to the insertion rod 29 provided in the retaining plate 1831, as the retaining plate 1831 extends into the inner groove 201, the iron block 32 at the end of the insertion rod 29 will be attracted by the magnet 25 located in the inner groove 201, thereby causing the insertion rod 29, which was originally stuck in the insertion hole 28 on the rotating shaft 27, to be pulled out. This releases the rotation limit of the retaining flap 1832 on the retaining plate 1831. The soil that was originally piled up at the soil breaking blade 182 will be pushed and flipped by gravity, allowing this part of the soil to fall into the mixing box 181.

[0068] S4: The liquid storage tank 13 is connected to the external fertilizer tank, and liquid fertilizer is added into the liquid storage tank 13. As rotation continues, since the soil retaining plate 1831 and the soil retaining flap 1832 are connected by a fourth return spring, and there is no soil pressure, the soil retaining plate 1831 and the soil retaining flap 1832 will return to a flush state under the action of the fourth return spring. The soil retaining plate 1831, which was originally located in the side groove 20, is pushed out again. The iron block 32 is no longer attracted by the magnet 25, but is reset and inserted into the rotating shaft 27 under the action of the third return spring 33. The insertion hole 28 on the upper part realizes the rotation limit of the soil retaining flap 1832 on the soil retaining slide plate 1831. Since the linkage ring 16 has an inner cavity and the inner cavity is connected to the telescopic cylinder 15, the liquid fertilizer in the liquid storage tank 13 will enter the linkage ring 16 through the telescopic cylinder 15, and then enter the mixing shaft 22 through the rubber hose 21. The rubber hose 21 is rotatably connected to the mixing shaft 22 through the rotating cap, and is discharged from the fertilizer outlet hole 34 on the mixing shaft 22. Then the drive gear 24 drives the driven gear 23 to rotate the mixing shaft 22, thus completing the mixing of liquid fertilizer and soil.

[0069] S5: As the rotation continues, when the opening of the mixing box 181 containing the soil and fertilizer mixture is vertically downward, the retaining plate 183, which abuts against the outer wall of the end column 19, will retract back into the side groove 20 located horizontally on the end column 19 under the action of the first return spring 185. Repeat the above operation. At this time, the retaining flap 1832 flips in the opposite direction under the action of the soil, allowing the soil to be poured out of the mixing box 181. As the rotation continues, the retaining plate 183 will cover the opening of the mixing box 181 again, thus forming the function of digging, mixing, and refilling soil.

The rubber hose (21) is connected to the fertilizer outlet holes (34).

10. A method of using an intelligent hilling device for soybean production, applied to the intelligent hilling device for soybean production as described in claim 9, characterized in that, The specific steps are as follows: S1: First, adjust the position of the first sliding frame (7) on the main beam (1) according to the distance between two adjacent soybean seedlings. Then, fix the first sliding frame (7) on the main beam (1) by spiral positioning. At this time, the side swing frames (2) on both sides of the main beam (1) will open at the angle according to the adjustment, so that the soil-building operation is only applied to the soil between two adjacent soybean seedlings, thereby completing the soil-building between them. This makes the direction of rotation of the digging part (18) at the bottom of the third sliding frame (9) always face the direction of movement of the main beam (1). S2: By turning on the external drive motor, the drive screw (5) on the rotating shaft platform (4) is driven to rotate. The threaded hole on the side swing frame (2) is matched with the drive screw (5), which will drive the side swing frame (2) to slide up and down on both sides of the end cylinder (3), thereby controlling the depth of the soil cutting part (18) into the soil. S3: The drive ring (14) symmetrically sleeved on the outer wall of the liquid storage cylinder (13) is driven to rotate by the external drive device, and drives the linkage ring (16) and multiple mixing boxes (181) on the linkage ring (16) to rotate together through the thin rod. The mixing box (181) is provided with a U-shaped soil-breaking blade (182) on one side. In this way, the linkage ring (16) drives the soil-breaking blade (182) on the mixing box (181) to rotate and dig soil. As the rotation continues and the opening of the mixing box (181) faces vertically upward, the retaining plate (183) that was originally abutting against the outer wall of the end post (19) will retract into the side groove (20) located horizontally on the end post (19) under the action of the first return spring (185). At the same time, due to the insertion rod (29) provided in the retaining plate (1831), as the retaining plate (1831) extends into the inner groove (201), the iron block (32) at the end of its insertion rod (29) will... The soil will be attracted by the magnet (25) located in the built-in groove (201), which will cause the plug (29) that was originally stuck in the insertion hole (28) on the rotating shaft (27) to be pulled out, thereby releasing the rotation limit of the retaining flap (1832) on the retaining slide plate (1831). The soil that was originally piled up at the soil breaking blade (182) will be pushed by gravity to flip the retaining flap (1832) and let this part of the soil fall into the mixing box (181). S4: The liquid storage tank (13) is connected to the external fertilizer tank and liquid fertilizer is added into the liquid storage tank (13). As the rotation continues, since the soil retaining plate (1831) and the soil retaining flap (1832) are connected by a fourth return spring, and without the pressure of soil, the soil retaining plate (1831) and the soil retaining flap (1832) will become flush again under the action of the fourth return spring. The rubber hose (21) is rotatably connected to the stirring shaft (22) through the rotating cap and discharged from the fertilizer outlet (34) on the stirring shaft (22), thus completing the mixing of liquid fertilizer and soil. S5: When the mixing box (181) containing soil and fertilizer continues to rotate, and the opening is vertically downward, the retaining plate (183) that abuts against the outer wall of the end column (19) will retract back into the side groove (20) located horizontally on the end column (19) under the action of the first return spring (185). Repeat the above operation to form the function of digging, mixing and refilling soil.
