Description

Technical Field

[0001] This invention relates to the field of equipment technology for treating albic soil, specifically a layered application device for albic soil improving microbial agents. Background Technology

[0002] Albic soils have a thin humus layer, poor permeability, and are prone to both waterlogging and drought, leading to a high risk of crop yield reduction. However, improving albic soils through cultivation and fertilization can effectively enhance soil fertility and disaster resistance, thereby increasing agricultural production.

[0003] Current technology involves creating horizontal and vertical trenches in alkaline soil, then applying different proportions of microbial agents to each trench based on the distribution characteristics of microorganisms at different depths. This stratified fertilization method offers significant improvement advantages. However, this method requires airflow to power the transport of fertilizer to the horizontal trenches. While airflow ensures smooth fertilizer delivery, excessive airflow pressure at the pipe outlet can cause fertilizer in the horizontal trenches to be blown into the vertical trenches. This not only reduces the fertilizer concentration in the horizontal trenches but also disrupts the microbial composition in the vertical trenches, thus negating the therapeutic advantages of the original microbial composition.

[0004] Therefore, we propose a stratified application device to reduce the air pressure at the fertilizer outlet in a transverse trench for the stratified application of microbial agents to stabilize albic soil. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1) This device has a rotatable receiving box in the fertilizer horizontal pipe, and then the receiving box is opened with a feed hole and a discharge port; when the fertilizer horizontal pipe drives the square air hole to rotate into the horizontal groove, the receiving box will rotate one revolution accordingly. When the feed hole of the receiving box is connected to the fertilizer vertical pipe, the improved microbial agent enters the receiving box under the action of wind. At this time, the discharge port of the receiving box is facing upward, and its outer wall will block the strip hole. The improved microbial agent will settle in the receiving box, and the airflow will be discharged from the square air hole, which will not blow to the bottom of the horizontal groove, thus preventing the improved microbial agent from being blown away. When the discharge port of the receiving box is aligned with the strip hole of the fertilizer horizontal pipe, the improved microbial agent in the receiving box passes through the discharge port and the strip hole in sequence under the action of gravity and is sprinkled into the horizontal groove. At the same time, the outer wall of the receiving box will block the outlet of the fertilizer vertical pipe, and the fertilizer in the fertilizer vertical pipe cannot enter the receiving box. At this time, the air flow that can enter the receiving box is small and cannot blow away the improved microbial agent in the horizontal groove. Continue rotating the receiving box. When the discharge port of the receiving box is misaligned with the strip hole of the fertilizer horizontal pipe and the inlet is not connected to the fertilizer vertical pipe, stop after one revolution of the receiving box. Then the fertilizer horizontal pipe enters the vertical trench. Because the inlet of the receiving box is misaligned with the outlet of the fertilizer vertical pipe and the discharge port is misaligned with the strip hole of the fertilizer horizontal pipe, the improving agent is blocked in the fertilizer vertical pipe, preventing the improving agent from entering the vertical trench.

[0015] 2) This device uses the cooperation of a cam and an arc-shaped push plate to move a limiting plate, causing it to separate from or engage with a synchronous gear, thus selectively controlling the steering bevel gear; it also uses a guide rail groove to move a positioning plate, causing it to separate from or engage with a positioning gear, thus selectively controlling the positioning bevel gear; this allows the receiving box to rotate or stop automatically when the fertilizer vertical pipe rotates, making the control of the receiving box more convenient.

Detailed Implementation

[0018] 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.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Example 1: Please see Figure 1-9 This invention provides a technical solution: a layered application device for a soil amendment microbial agent, comprising a frame 11, a flat support on the upper side of the frame 11, and an air supply mechanism 31, a storage tank 13, a controller 14, and a battery mounted on the upper side of the support. The air supply mechanism 31 (which can be an air compressor or a fan) generates airflow to propel the amendment microbial agent, ensuring that the amendment microbial agent in the pipeline can smoothly enter the soil. The storage tank 13 is divided into a first tank and a second tank, where the first tank stores the amendment microbial agent for the soil layer and the second tank stores the amendment microbial agent for the clay deposition layer; the amendment microbial agent in the storage tank 13 can flow into the pipeline under gravity. The battery is electrically connected to the air supply mechanism 31 to supply it with power. A depth-limiting wheel 21 is mounted on the lower side of the flat support of the frame 11, and a hanging rod 12 is hinged to the outer side of the frame 11. The hanging rod 12 is connected to an external traction vehicle, allowing the device to be moved by the external traction vehicle. A hollow support is provided on the lower side of the frame 11, and a transmission component is installed on the inner side of the hollow support.

[0021] A deep loosening shovel 41 is installed on the lower side of the hollow support on the frame 11. Each deep loosening shovel 41 is equipped with 2N (N is a positive integer) shovel wings 42, which are symmetrically distributed on both sides of the deep loosening shovel 41. During operation, the deep loosening shovel 41 cuts vertical grooves, and the shovel wings 42 cut transverse grooves on the sidewalls of the vertical grooves. The number of shovel wings 42 is related to the number of transverse grooves to be cut, where the number of transverse grooves is N.

[0022] A fertilizer vertical pipe 52 is rotatably mounted on the hollow support of the frame 11. A fertilizer horizontal pipe 53 is connected to the lower outer end of the fertilizer vertical pipe 52, and the position of the fertilizer horizontal pipe 53 is aligned with the shovel wing 42. The upper end of the fertilizer vertical pipe 52 is connected to the first box of the storage box 13. When the fertilizer vertical pipe 52 drives the fertilizer horizontal pipe 53 to rotate, the white slurry layer improving agent enters the fertilizer horizontal pipe 53 through the fertilizer vertical pipe 52, and then enters the transverse trench through the fertilizer horizontal pipe 53. Each transverse trench corresponds to a set of fertilizer vertical pipes 52 and fertilizer horizontal pipes 53. A support pipe 51 is fixedly mounted on the hollow support of the frame 11. The support pipe 51 is connected to the second box, and the adhesive deposition layer improving agent enters the vertical trench through the support pipe 51. The support pipe 51 is a metal pipe with a large wall thickness. A fertilizer pipe support is installed on its outer side. The fertilizer vertical pipe 52 passes through the fertilizer pipe support and is connected to the inner wall of the fertilizer pipe support through a bearing. The support pipe 51 supports the fertilizer vertical pipe 52, which can improve its stability.

[0023] Inside the hollow support of the frame 11, there are two discharge mechanisms: a first discharge mechanism 33 and a second discharge mechanism 34 (the discharge mechanism is existing technology and is mainly used to control the falling speed of the improved microbial agent, which will not be described in detail here). The inlet of the first discharge mechanism 33 is connected to the first box of the storage box 13. The white slurry layer improved microbial agent in the first box will enter the first discharge mechanism 33 under the action of gravity. The outlet of the first discharge mechanism 33 is connected to the feeding pipe 32 through a tee. One end of the feeding pipe 32 is connected to the air outlet of the air supply mechanism 31, and the other end is connected to the upper end of the fertilizer vertical pipe 52 through a rotary joint 35. A valve (not shown in the figure) is provided on the feeding pipe 32 to control the air flow. The first discharge mechanism 33 sends the white slurry layer improved microbial agent into the feeding pipe 32, and then the air supply mechanism 31 blows out the airflow to send it into the fertilizer vertical pipe 52, and discharges it into the transverse trench from the fertilizer horizontal pipe 53. The inlet of the second discharge mechanism 34 is connected to the second box of the storage box 13. The adhesive deposition layer improver in the second box will enter the second discharge mechanism 34 under the action of gravity. The second discharge mechanism 34 sends the adhesive deposition layer improver into the support pipe 51, and then it will automatically be discharged from the lower end of the support pipe 51 into the vertical groove under the action of gravity.

[0024] The hollow support of the frame 11 houses the main shaft 61 and a main shaft motor (not shown in the figure) that drives the main shaft 61 to rotate. The main shaft 61 is connected to the hollow support via bearings. The battery and controller 14 are electrically connected to the main shaft motor. The battery supplies power to the main shaft motor, and the controller 14 controls the speed of the main shaft motor. A first drive pulley 621 and a second drive pulley 631 are fitted on the outer side of the main shaft 61. A first driven pulley 622 is fitted on the outer side of the rotating shaft of the first discharge mechanism 33. The first drive pulley 621 is connected to the first driven pulley 622 via a belt. A second driven pulley 632 is fitted on the outer side of the rotating shaft of the second discharge mechanism 34. The second drive pulley 631 is connected to the second driven pulley 632 via a belt.

[0025] A first bevel gear 623 is also fitted on the outside of the rotating shaft of the first discharge mechanism 33. A second bevel gear 624 and a first sprocket 625 are rotatably connected on the hollow bracket. The second bevel gear 624 and the first sprocket 625 are coaxially connected. A buffer 70 is fitted on the outside of the fertilizer vertical pipe 52. A second sprocket 626 is fitted on the outside of the buffer 70. The first sprocket 625 and the second sprocket 626 are connected by chain drive. The rotating shaft of the first discharge mechanism 33 is linked with the fertilizer vertical pipe 52, which makes the discharge speed of the first discharge mechanism 33 and the rotation speed of the fertilizer vertical pipe 52 have good synchronization, thus facilitating synchronous control of the two. That is, when the rotation speed of the fertilizer vertical pipe 52 is faster, the rotating shaft of the first discharge mechanism 33 also rotates faster, so that more white slurry layer improving bacteria agent can enter the fertilizer vertical pipe 52, thereby increasing the application speed of the improving bacteria agent; conversely, if the rotation speed of the fertilizer vertical pipe 52 is reduced, the amount of white slurry layer improving bacteria agent entering the fertilizer vertical pipe 52 will also be reduced accordingly.

[0026] The lower inner wall of the fertilization horizontal pipe 53 has a strip-shaped hole. The white slurry layer improving microbial agent in the fertilization horizontal pipe 53 can be discharged through the strip-shaped hole under gravity and enter the transverse groove. A square air hole is opened on the upper outer wall of the fertilization horizontal pipe 53 at the end furthest from the fertilization vertical pipe 52. The large size of the hole facilitates airflow dispersion, thereby reducing the airflow velocity. The white slurry layer improving microbial agent carried in the airflow falls automatically under gravity. A staggered dust baffle 531 is installed in the square air hole. The dust baffle 531 is tilted downwards, blocking some of the white slurry layer improving microbial agent from being blown out, thus reducing the possibility of the white slurry layer improving microbial agent being blown out of the fertilization horizontal pipe 53. If the wind force is too strong, a protective net (not shown in the figure) can be installed at the end of the square air hole to further reduce the possibility of the white slurry layer improving microbial agent being blown out.

[0027] A receiving box 561 is rotatably connected to the inner wall of the fertilization horizontal pipe 53. The section of the receiving box 561 furthest from the fertilization vertical pipe 52 is semi-cylindrical, while the section closest to the fertilization vertical pipe 52 is cylindrical. Both the upper semi-cylindrical and cylindrical sections of the receiving box 561 are hollow, allowing it to receive the white slurry layer improving microbial agent. Its outer wall is in contact with the inner wall of the fertilization horizontal pipe 53. The outer wall of the cylindrical section of the receiving box 561 has an inlet hole 562 corresponding to the outlet of the fertilization vertical pipe 52. The open portion on the outer side of the semi-cylindrical section serves as the discharge port of the receiving box 561. Wind baffles 563 are welded to the inner wall of the semi-cylindrical section of the receiving box 561. Multiple wind baffles 563 are staggered, blocking airflow from different directions. The wind baffles 563 disrupt the airflow, facilitating the settling of the white slurry layer improving microbial agent. When the feed hole 562 is aligned with the outlet of the fertilizer vertical pipe 52, the white slurry layer improver can enter the receiving box 561 through the feed hole 562. At this time, the outer wall of the receiving box 561 blocks the strip hole on the lower side of the inner wall of the fertilizer horizontal pipe 53, making it difficult for airflow to escape from the strip hole, thus preventing the airflow from blowing away the white slurry layer improver sprinkled into the horizontal groove. When the feed hole 562 is misaligned with the outlet of the fertilizer vertical pipe 52, the opening of the receiving box 561 is aligned with the strip hole. Under the action of gravity, the white slurry layer improver inside the receiving box 561 is sprinkled into the horizontal groove from the strip hole. At this time, the outer wall of the receiving box 561 blocks the outlet of the fertilizer vertical pipe 52, making it difficult for airflow to enter the fertilizer horizontal pipe 53, thus preventing the airflow from escaping and sprinkling the white slurry layer improver sprinkled into the horizontal groove.

[0028] An adjusting chamber 54 is installed at the lower end of the fertilizer vertical pipe 52. The rotating shaft of the receiving box 561 extends into the inner side of the adjusting chamber 54, and a synchronous gear 564 and a steering bevel gear 565 are sleeved on its outer wall. A limiting plate 593 is slidably installed on the inner wall of the adjusting chamber 54. The limiting plate 593 has an internal gear groove corresponding to the synchronous gear 564. When the internal gear groove is engaged with the outer side of the synchronous gear 564, the synchronous gear 564 is fixed, and the receiving box 561 cannot rotate. A guide post 592 is connected to the side of the limiting plate 593 away from the receiving box 561. A return spring 594 is sleeved on the outer side of the guide post 592. The other end of the return spring 594 is in contact with the inner wall of the adjusting chamber 54. The return spring 594 is used to push the limiting plate 593 to move away from the fertilizer vertical pipe 52. An arc-shaped push plate 591 is connected to the other end of the guide post 592.

[0029] A central shaft 581 is rotatably connected to the inner side of the regulating chamber 54. A cam 584, a positioning bevel gear 583, and a positioning gear 582 are sleeved on the outer side of the central shaft 581. The cam 584 is fixedly connected to the central shaft 581, and the positioning bevel gear 583 is coaxially connected to the positioning gear 582 and is movably sleeved on the outer side of the central shaft 581 through a bearing. The positioning bevel gear 583 meshes with the steering bevel gear 565. The cam 584 is located on the inner side of the arc-shaped push plate 591. Rotation of the cam 584 can push the arc-shaped push plate 591 to move away from the receiving box 561. A circular protrusion is provided on the inner side of the arc-shaped push plate 591, which abuts against the cam 584.

[0030] A control chamber 55 is connected to the outer side of the support tube 51 via a thick tube bracket. The control chamber 55 is located below and rotatably connected to the adjustment chamber 54. The lower end of the central shaft 581 is fixedly connected to the bottom wall of the adjustment chamber 54, and a spline groove is formed on the inner wall of the adjustment chamber 54. A spline is provided on the outer side of the positioning plate 572, and it is slidably connected to the adjustment chamber 54 through spline engagement. A positioning tooth groove adapted to the positioning gear 582 is formed on the upper side of the positioning plate 572. When the positioning tooth groove meshes with the positioning gear 582, the positioning gear 582 is fixed, and the cam 584 and the positioning bevel gear 583 on its outer side cannot rotate. A thrust spring 571 is connected between the lower side of the positioning plate 572 and the bottom wall of the control chamber 55. The thrust spring 571 is used to push the positioning plate 572 upward, so that the positioning tooth groove meshes with the positioning gear 582.

[0031] The lower end of the adjustment chamber 54 is provided with a guide rail groove 541, which includes a lower convex section and an upper concave section. The upper outer end of the positioning plate 572 is provided with a synchronization plate 573, the upper end of which abuts against the guide rail groove 541. When the upper end of the synchronization plate 573 is in the lower convex section, the adjustment chamber 54 forces the positioning plate 572 to be in the lower position through the synchronization plate 573, and the positioning tooth groove on the positioning plate 572 separates from the positioning gear 582. When the upper end of the synchronization plate 573 is in the upper concave section, the thrust spring 571 is used to push the positioning plate 572 upward, so that the positioning tooth groove meshes with the positioning gear 582. In order to reduce frictional resistance, a ball groove is provided on the upper side of the synchronization plate 573, and a ball is placed inside the ball groove.

[0032] The reset spring 594, limit plate 593, guide post 592, arc-shaped push plate 591, cam 584, positioning bevel gear 583, positioning gear 582, central shaft 581, synchronization plate 573, positioning plate 572, thrust spring 571, steering bevel gear 565, and synchronization gear 564 together form the adjustment mechanism that drives the receiving box 561 to rotate.

[0033] A photoelectric encoder is installed on the hollow support of the frame 11. The encoder disk with a grating on the photoelectric encoder is installed on the outside of the fertilizer vertical pipe 52. The photoelectric encoder is electrically connected to the controller 14 and the battery. When the photoelectric encoder detects the grating, the support pipe 51, fertilizer vertical pipe 52, and fertilizer horizontal pipe 53 are on the same plane. Before the support pipe 51, fertilizer vertical pipe 52, and fertilizer horizontal pipe 53 enter and exit the alkaline soil, the controller 14 first determines whether the photoelectric encoder can detect the grating. If it can detect it, the support pipe 51, fertilizer vertical pipe 52, and fertilizer horizontal pipe 53 can directly enter or exit the soil; if it cannot detect it, the controller 14 drives the main shaft motor to rotate, which drives the fertilizer vertical pipe 52 to rotate until the photoelectric encoder detects the grating.

[0034] During the movement of this device, the sinusoidal curve of the trajectory of the end of the fertilizer application pipe 53 (see...) Figure 8 The movement trajectory of the receiving box 561 inside the fertilizer horizontal pipe 53 is the same as that of the fertilizer horizontal pipe 53, but its rotation is divided into a rotating area and a fixed area (see Figure 9 The rotating zone is mainly located in the transverse groove. At this time, the adjusting mechanism drives the receiving box 561 to rotate. The rotating zone includes a fertilizer receiving area, a fertilizer application area, and a blank area. When the receiving box 561 is in the fertilizer receiving area, its inlet 562 is connected to the fertilizer application vertical pipe 52, and the wind blows the white slurry layer improving microbial agent into the receiving box 561. When the receiving box 561 is in the fertilizer application area, its outlet is aligned with the strip hole of the fertilizer application horizontal pipe 53, and the white slurry layer improving microbial agent is discharged under gravity. When the receiving box 561 is in the fixed area, its outlet is offset from the strip hole of the fertilizer application horizontal pipe 53, and its inlet 562 is offset from the fertilizer application vertical pipe. When the receiving box 561 is in the fixed area, it is fixed and cannot rotate. To ensure rotation feasibility, the transmission ratio of the steering bevel gear 565 and the positioning bevel gear 583 is set to 3:1.

[0035] Example 2: Please see Figure 10 The present invention provides a technical solution: a layered application device for a white soil improving microbial agent. Based on the first embodiment, the buffer 70 includes an outer sleeve 71, an inner limiting ring 72, and a reset disc spring 73.

[0036] The second sprocket 626 is fitted onto the outside of the outer sleeve 71 and is fixedly connected; the inner limiting ring 72 is fitted onto the outside of the fertilizer vertical pipe 52 and is fixedly connected; a return disc spring 73 is connected to the outer wall of the inner limiting ring 72, and the other end of the return disc spring 73 is connected to the inner wall of the outer sleeve 71. A limiting protrusion 721 is provided on the outer side of the inner limiting ring 72, and a limiting groove 711 corresponding to the limiting protrusion 721 is provided on the inner side of the outer sleeve 71. The limiting groove 711 is used to limit the rotation angle of the limiting protrusion 721. The return disc spring 73 stores elastic potential energy and can drive the inner limiting ring 72 to rotate, so that the upper limiting protrusion 721 of the inner limiting ring 72 fits against one side of the inner wall of the limiting groove 711. When the horizontal fertilizer pipe 53 is blocked by hard objects such as stones in the horizontal groove during rotation, the horizontal fertilizer pipe 53 can drive the vertical fertilizer pipe 52 to rotate around the hard object, thus avoiding excessive pressure from the hard object on the horizontal fertilizer pipe 53. After bypassing the hard object, the reset disc spring 73 will push the vertical fertilizer pipe 52 to rotate and reset.

[0037] Example 3: Please see Figure 11-12 This invention provides a technical solution: a layered application device for a soil-improving microbial agent. Based on Embodiment 1, the lower side of the flat support of the frame 11 is further equipped with a height adjustment guide rail 24, a height adjustment push rod 26, and a positioning locking plate 27. A height adjustment slider 25 is slidably mounted on the height adjustment guide rail 24, and the telescopic end of the height adjustment push rod 26 is connected to the height adjustment slider 25. An adjustment shaft is rotatably connected to the positioning locking plate 27, and adjustment rods 29 are fixedly connected to both ends of the adjustment shaft. A wheel axle 22 is rotatably connected between the two adjustment rods 29, and a depth-limiting wheel 21 is fixed to both ends of the wheel axle 22. A transition shaft 28 is also connected between the two adjustment rods 29, and a connecting rod 23 is rotatably connected to the outer side of the transition shaft 28. The other end of the connecting rod 23 is hinged to the height adjustment slider 25. By pushing the height adjustment slider 25 to slide through the height adjustment push rod 26, and driving the adjustment rods 29 to rotate through the connecting rod 23 and the transition shaft 28, the ground clearance of the adjustment shaft and the positioning locking plate 27 is adjusted. By adjusting the ground clearance of the positioning locking plate 27, the ground clearance of the frame 11 can be adjusted, thereby adjusting the depth of the deep loosening shovel 41 and shovel wing 42. At the same time, when the frame 11 is raised, the rotation of the adjusting rod 29 pushes the wheel axle 22 to move towards the middle part of the frame 11, which is beneficial to the stability of the machine.

[0038] A locking gear 291 is provided on the side of the adjusting rod 29 near the positioning locking plate 27. A locking sleeve 272 corresponding to the locking gear 291 is slidably installed on the inner side of the positioning locking plate 27. A spline groove is provided on the inner side of the positioning locking plate 27, and a corresponding spline is provided on the outer side of the locking sleeve 272. An electromagnetic push rod 271 is fixedly installed on the inner side of the positioning locking plate 27. The telescopic end of the electromagnetic push rod 271 is connected to the locking sleeve 272 and is used to push the locking sleeve 272 to engage or disengage from the locking gear 291. When the locking sleeve 272 engages with the locking gear 291, the locking gear 291 is fixed, and the adjusting rod 29 and the adjusting shaft cannot rotate. At this time, the height of the frame 11 from the ground is fixed and cannot be adjusted. When the locking sleeve 272 disengages from the locking gear 291, the locking gear 291, the adjusting rod 29, and the adjusting shaft can rotate. At this time, the height of the frame 11 from the ground can be adjusted. The height adjustment push rod 26 is an electric push rod, and the battery, controller 14, height adjustment push rod 26 and electromagnetic push rod 271 are electrically connected.

[0039] Working principle: The white slurry layer improving bacteria agent in the first box of the storage box 13 enters the first discharge mechanism 33 under the action of gravity; the viscous deposition layer improving bacteria agent in the second box of the storage box 13 enters the second discharge mechanism 34 under the action of gravity; the second discharge mechanism 34 guides the viscous deposition layer improving bacteria agent into the support pipe 51, and discharges it into the vertical groove opened by the deep loosening shovel 41 under the action of gravity; the first discharge mechanism 33 guides the white slurry layer improving bacteria agent into the feeding pipe 32, and at the same time, the air supply mechanism 31 blows the white slurry layer improving bacteria agent in the feeding pipe 32 into the fertilizer vertical pipe 52 through airflow, and enters the receiving box 561 inside the fertilizer horizontal pipe 53 through the inlet hole 562.

[0040] When the fertilizing horizontal pipe 53 is located in the vertical groove, the long side of the cam 584 abuts against the arc-shaped push plate 591. The arc-shaped push plate 591 drives the limiting plate 593 to be sleeved on the outside of the synchronous gear 564 through the guide post 592. At this time, the receiving box 561 is restricted and cannot rotate. At the same time, the upper end of the synchronous plate 573 is located on the lower convex section of the guide rail groove 541. The adjusting chamber 54 forces the positioning plate 572 to separate from the positioning gear 582 through the synchronous plate 573. At this time, the positioning gear 582 and the positioning bevel gear 583 can rotate. That is, at this time, the fertilizing vertical pipe 52 drives the fertilizing horizontal pipe 53 to rotate, and the fertilizing horizontal pipe 53 drives the receiving box 561 and the steering bevel gear 565 to rotate around the central axis 581. At the same time, the steering bevel gear 565 drives the positioning bevel gear 583 to rotate.

[0041] When the horizontal fertilizer pipe 53 is located in the transverse trench, the vertical fertilizer pipe 52 drives the adjusting chamber 54 and its internal arc-shaped push plate 591 to rotate. At this time, the arc-shaped push plate 591 abuts against the corresponding short side of the cam 584, and the return spring 594 pushes the limiting plate 593 to separate from the synchronous gear 564. At this time, the synchronous gear 564, the receiving box 561, and the steering bevel gear 565 can rotate. Simultaneously, the upper end of the synchronous plate 573 is located in the upper concave section of the guide rail groove 541, and the thrust spring 571 pushes the positioning plate 572 to move upward. Positioning plate 572 meshes with positioning gear 582. At this time, central shaft 581, positioning gear 582, and positioning bevel gear 583 cannot rotate. That is, at this time, fertilization vertical pipe 52 drives fertilization horizontal pipe 53 to rotate, and fertilization horizontal pipe 53 drives receiving box 561 and steering bevel gear 565 to rotate around central shaft 581. At the same time, steering bevel gear 565 rotates and drives receiving box 561 to rotate. When the discharge port of receiving box 561 is downward, the white slurry layer of improved microbial agent in receiving box 561 enters the transverse groove under the action of gravity.
