Description

Technical Field

[0001] This utility model relates to the field of land fertilization technology, and in particular to a strip application machine for organic fertilizer under mulch film. Background Technology

[0002] In agricultural production, crops need to be fertilized before or after planting to improve their survival rate and yield. Farmyard manure, also known as organic fertilizer, includes pure sheep manure, pure chicken manure, a mixture of chemical fertilizer and sheep manure, a mixture of chemical fertilizer and chicken manure, and a mixture of organic fertilizer and bio-fertilizer. Traditionally, farmyard manure is applied by spreading it on the soil surface, followed by tilling with agricultural machinery to mix the fertilizer with the soil. The application rate can reach 1-several cubic meters per acre. However, this method of applying farmyard manure has the following problems: insufficient precision in fertilization. Traditional spreading combined with tilling makes it difficult to control the distribution location or depth of fertilizer in the soil. For example, when transplanting chili peppers, organic fertilizer and bio-fertilizer are best applied to a depth of 10-15 cm below the soil surface. However, existing agricultural machinery cannot achieve precise positioning during tillage, resulting in reduced fertilizer utilization. Furthermore, full-coverage fertilization requires a large amount of fertilizer. Precise strip or hole application usually involves fertilizing multiple points simultaneously, requiring a large area to be covered in a single operation. This necessitates the use of large-capacity fertilizer storage devices. However, high-efficiency organic fertilizers made by mixing pure sheep manure and pure chicken manure with chemical fertilizers after secondary composting and sieving have fine particles and high viscosity. When stored in large-capacity fertilizer storage devices for fertilization, friction, moisture, or particle agglomeration can easily clog the fertilizer discharge channels, preventing the fertilizer from being discharged smoothly from the storage device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an organic fertilizer strip applicator under ridge film, which is mainly used for applying farmyard manure. When a large amount of farmyard manure is stored in the fertilizer box for fertilization, the organic fertilizer will not block the fertilizer channel, thus achieving the purpose of rapid fertilizer application.

Detailed Implementation

[0023] The present invention will be further described below.

[0024] This utility model provides a strip application machine for organic fertilizer under ridge film, mainly used for applying farmyard manure. It includes a rotary tiller and film-laying integrated machine, comprising a main beam 11 on the machine body. A fertilizer box 2 is mounted on the main beam 11, and a fertilizer dispensing mechanism 3 is located at the bottom of the fertilizer box 2. A soil-feeding device 4 is connected below the fertilizer dispensing mechanism 3. The fertilizer box 2 has a trapezoidal structure, wider at the top and narrower at the bottom. Fertilizer dispensing holes 21 are spaced apart at the bottom of the fertilizer box 2. A first mixer 22 is also located above the fertilizer dispensing holes 21 inside the fertilizer box 2. The first mixer 22 includes horizontally arranged... The fertilizer box 2 contains a first rotating shaft 221. A winch 222 is circumferentially arranged on the first rotating shaft 221 along its length. A stirring rod 223 is also provided on the first rotating shaft 221, perpendicular to and extending away from it. The stirring rods 223 are spaced apart on the first rotating shaft 221 and correspond one-to-one with the fertilizer inlet holes 21. Both ends of the first rotating shaft 221 pass through the fertilizer box 2 and are rotatably connected to it. The fertilizer dispensing mechanism 3 includes a rectangular fertilizer dispensing box 31. The upper surface of the fertilizer dispensing box 31 is connected to the bottom of the fertilizer box 2. The box 31 is equipped with a second mixer 32, which includes a second rotating shaft 321 arranged horizontally inside the fertilizer box 31. A winch 222 is arranged circumferentially on the second rotating shaft 321 along its length. Both ends of the second rotating shaft 321 pass through the fertilizer box 31 and are rotatably connected to it. The upper surface of the fertilizer box 31 has upper fertilizer inlet holes 33 aligned with the fertilizer outlet holes 21. The lower surface of the fertilizer box 31 has lower fertilizer outlet holes 34. Below each lower fertilizer outlet hole 34 is a fertilizer outlet pipe 35 for connecting to the soil entry device 4. Below the fertilizer pipe 35, there is a crossbar 12 arranged along the length of the lower fertilizer box 31. The end of the crossbar 12 is connected to a telescopic mechanism that drives the crossbar 12 to move up and down. The soil-entry device 4 includes a soil-entry steel pipe 41 vertically arranged on the crossbar 12. The soil-entry steel pipe 41 is arranged below each lower fertilizer pipe 35 in sequence. A flexible hose 351 for connection is provided between each lower fertilizer pipe 35 and the soil-entry steel pipe 41. The lower end of the soil-entry steel pipe 41 is provided with a bevel 42. Soil-retaining plates 43 are provided on both sides of the bevel 42. The first mixer 22 and the second mixer 32 are driven by a drive mechanism 6.

[0025] like Figures 1-7As shown, the ridge-mulch organic fertilizer strip application machine includes a rotary tiller and mulch-laying integrated machine for rotary tilling and mulching the land. Specifically, the rotary tiller and mulch-laying integrated machine can adopt existing structures as described in CN219894064U "A Rotary Tiller and Mulch-Laying Machine" or CN205694112U "Adjustable Width Rotary Tiller and Mulch-Laying Machine Between Rows of Fruit Trees," and is suspended on a tractor for rotary tilling and mulching. The rotary tiller and mulch-laying integrated machine is equipped with a main beam 11. A fertilizer box 2 is installed on the main beam 11. The fertilizer box 2 can be directly installed above the mulch-laying machine using the frame. The fertilizer box 2 adopts a trapezoidal structure that is wider at the top and narrower at the bottom, which is beneficial for the storage and falling of organic fertilizer. A first mixer 22 is installed inside the fertilizer box 2 to mix the organic fertilizer stored in the fertilizer box 2, preventing it from solidifying inside the fertilizer box 2. Unable to smoothly dispose of fertilizer, the first mixer 22 includes a first rotating shaft 221 horizontally arranged inside the fertilizer application area. Both ends of the first rotating shaft 221 pass through the fertilizer application box 2 and are mounted on the body of the rotary tillage and mulching machine through bearing seats. Specifically, a corresponding frame can be set on the body according to the position of the first rotating shaft 221. Winches 222 are arranged circumferentially along the length of the first rotating shaft 221. The winches 222 are used to stir the organic fertilizer stored in the fertilizer application box 2. In addition, in order to ensure that the fertilizer at each fertilizer application hole 21 is not blocked, stirring rods 223 corresponding to each fertilizer application hole 21 are installed on the first rotating shaft 221. The stirring rods 223 are perpendicular to the first rotating shaft 221 and stir the fertilizer above the fertilizer application hole 21 during the rotation of the first rotating shaft 221, making it loose so that it can fall into the fertilizer application box 31 located below the fertilizer application box 2.The fertilizer box 31 and the fertilizer application box 2 can be detachably connected by bolts or pins, or they can be directly welded into an integral structure. The top of the fertilizer box 31 has upper fertilizer inlet holes 33 that are aligned with the fertilizer inlet holes 21 one by one. The fertilizer box 31 is equipped with a second mixer 32. The second shaft 321 of the second mixer 32 is horizontally arranged in the fertilizer box 31 to mix the fertilizer in the fertilizer box 31 that has not yet been conveyed to the soil entry device 4, so as to avoid it from accumulating and solidifying into lumps that cannot be applied due to long-term accumulation. The two ends of the second shaft 321 of the second mixer 32 are horizontally arranged in the fertilizer box 31 and are rotatably connected to the fertilizer box 31. They are mounted on the body of the rotary tillage and mulching machine through bearing seats. Specifically, the second shaft 321 can be arranged according to the second shaft 321. The corresponding frame is set on the body of the rotary tillage and mulching machine. One end of the second rotating shaft 321 extending out of the fertilizer tank 31 is connected to the drive mechanism 6. The drive mechanism 6 drives the second rotating shaft 321 to rotate. The second rotating shaft 321 is also equipped with a winch 222, which is set along the length of the second rotating shaft 321 to rotate with the second rotating shaft 321 to stir the fertilizer stored in the fertilizer tank 31. The bottom of the fertilizer tank 31 has a fertilizer outlet hole 34. Each fertilizer outlet hole 34 is equipped with a fertilizer pipe 35. The fertilizer pipe 35 can be connected to the fertilizer outlet hole 34 by a flange or directly welded to the fertilizer tank 31. The fertilizer pipe 35 can be a cylindrical pipe or a square pipe, but it is important to ensure that the fertilizer can be smoothly distributed. For optimal downward flow, a funnel shape (wider at the top and narrower at the bottom) is best for the fertilizer inlet pipe 35. This allows the fertilizer to quickly enter the soil inlet device 4 connected to the fertilizer inlet pipe 35 under the influence of gravity and the squeezing action of the fertilizer inlet pipe 35. The soil inlet device 4 includes a vertically mounted steel pipe 41 on the horizontal bar 12. This steel pipe 41 is sequentially positioned below each fertilizer outlet pipe and connected to the fertilizer outlet hole 34 via a flexible hose 351. The flexible hose 351 can be an existing PVC telescopic pipe or a telescopic corrugated pipe, ensuring that the connection between the steel pipe 41 and the fertilizer outlet pipe 35 does not break when the horizontal bar 12 moves the steel pipe 41 up and down. The telescopic mechanism connected to the horizontal bar 12 drives the horizontal bar 12 to move up and down, thereby moving all the fertilizer outlet holes connected to the horizontal bar 12. The soil-inserting steel pipe 41 moves up and down to insert into the soil to be fertilized for fertilization. The telescopic mechanism can be an existing hydraulic telescopic rod or an electric push rod. To achieve synchronous movement of the left and right sides of the crossbar 12, a telescopic mechanism can be set at each end of the crossbar 12 and controlled by the same controller. To facilitate the smooth insertion of the soil-inserting steel pipe 41 into the soil for fertilization, the lower end of the soil-inserting steel pipe 41 is provided with a slanted cut 42 for insertion into the soil. At the same time, fertilizer can fall into the soil first from the shorter side of the slanted cut 42. To further ensure that the soil-inserting steel pipe 41 can be inserted into the soil smoothly, soil-retaining plates 43 are also provided on both sides of the slanted cut 42. While increasing the cutting force on the soil, they can also ensure that the soil on both sides of the slanted cut 42 of the soil-inserting steel pipe 41 will not affect the fertilization effect.The drive mechanism 6, which is connected to the first rotating shaft 221 and the second rotating shaft 321, can be directly connected to the first rotating shaft 221 and the second rotating shaft 321 via a motor 62.

[0026] This ridge-mulch organic fertilizer strip application machine incorporates an organic fertilizer strip application mechanism on an existing ridge-mulch machine. A first mixer 22 and a second mixer 32 are installed in the fertilizer tank 2 (for storing organic fertilizer) and the fertilizer discharge tank 31 (for temporary storage of organic fertilizer), respectively, to agitate the organic fertilizer and prevent it from solidifying and clogging the discharge channels due to friction, moisture, or particle agglomeration. For the fertilizer tank 2, which stores a large amount of organic fertilizer, the first mixer 22 has a stirring rod 223 perpendicular to the first rotating shaft 221 and corresponding to each fertilizer discharge hole 21. The stirring rod 223 further agitates the fertilizer at the fertilizer discharge holes 21, preventing blockage. Simultaneously, the beveled cut 42 of the soil-inserting steel pipe 41 facilitates insertion into the soil, and a retaining plate 43 prevents soil from entering the pipe 41 during the insertion process, ensuring smooth application of the organic fertilizer. The connection method of the soil and hose 351 allows the soil-inserting steel pipe 41 to move flexibly within a certain range, adapting to different terrains and operational requirements. This adjusts the insertion depth of the steel pipe 41 into the soil, preventing clogging of the fertilization channel during fertilization, achieving rapid and uniform fertilization, ensuring fertilization efficiency, and providing adjustable fertilization depth. Furthermore, when the fertilizer box is installed on the film-laying machine frame, the soil-inserting steel pipe can be directly positioned on both sides of the film-laying machine. While laying the film, the control bar moves the soil-inserting steel pipe downwards to achieve fertilization. For example, adding this strip fertilizer to an existing three-row ridging and film-laying machine allows for the installation of soil-inserting steel pipes on both sides of each film-laying machine, forming a three-film, six-row ridging film-under-film organic fertilizer strip fertilizer machine. That is, during operation, three rows of film are laid simultaneously, and fertilizer is applied to both sides of each row of film, totaling six fertilization points. The specific number of fertilizer pipes is set according to the actual film-laying volume required by the rotary tillage and film-laying integrated machine.

[0027] Furthermore, to prevent the fertilizer inlet pipe 35 and hose 351 from becoming too long, which could cause fertilizer blockage between them and prevent normal fertilizer dispensing, such as... Figure 5As shown, the second rotating shaft 321 is provided with a curved portion 322 corresponding to the lower fertilizer outlet 34. Each curved portion 322 is provided with a crankshaft ring 323 that is arranged around the top of the curved portion 322 and rotates around the curved portion 322. Each crankshaft ring 323 is fixed with a vertically downward connecting rod 324 that extends into the lower fertilizer pipe 35. The lower end of the connecting rod 324 is provided with a dredging spring 325 that extends into the soil entry steel pipe 41 along the hose 351. By providing a curved portion 322 corresponding to the lower fertilizer outlet 34 on the second rotating shaft 321, and setting a crankshaft ring 323 at the center of the curved portion 322, the crankshaft ring 323 is rotatably set at the top of the curved portion 322. When the curved portion 322 moves with the second rotating shaft 321, the crankshaft ring 323 rotates around the top of the curved portion 322. When the rotating shaft 321 starts to rotate, the crankshaft ring 323 moves in a circular motion around the second rotating shaft 321 with the bending part 322 as the center. At the same time, because the crankshaft ring 323 is provided with a vertically downward connecting rod 324 that extends into the lower fertilizer pipe 35, the connecting rod 324 moves up and down in the lower fertilizer pipe 35 with the crankshaft ring 323. This drives the unblocking spring 325 at the lower end of the connecting rod 324 to move up and down in the hose 351 and the soil entry steel pipe 41, so as to unblock the fertilizer in the lower fertilizer pipe 35, the hose 351 and the soil entry steel pipe 41 and avoid the problem of fertilizer blockage. In addition, the bending part 322 is set to correspond to the lower fertilizer outlet 34, which can also stir the fertilizer above the lower fertilizer outlet 34 again to prevent it from solidifying and ensure that it can be discharged smoothly.

[0028] To ensure that the fertilizer in the lower fertilizer tank 31 is discharged at a designated location, such as Figure 5 As shown, the upper fertilizer inlet 33 and the lower fertilizer outlet 34 are staggered and arranged on the lower fertilizer box 31. The fertilizer in the lower fertilizer box 31 is stirred and squeezed by the winch 222 set on the second rotating shaft 321, and controlled to fall from the lower fertilizer outlet 34. When the second rotating shaft 321 does not rotate, the fertilizer does not fall from the lower fertilizer outlet 34, thus controlling the fall of the fertilizer in the lower fertilizer box 31.

[0029] To facilitate adjustment of the spacing of the steel pipes 41 into the soil according to the planting needs of the crop, and to accommodate fertilizer holes of different widths, such as... Figure 5 , Figure 7As shown, the soil-inserting steel pipe 41 is detachably mounted on the crossbar 12. By adjusting the position of the soil-inserting steel pipe 41 on the crossbar 12, it can accommodate fertilizer holes of different widths. The connection between the soil-inserting steel pipe 41 and the crossbar 12 can be achieved by using a pipe clamp 44 to mount the soil-inserting steel pipe 41 on the crossbar 12. The crossbar 12 has connecting holes 121 for the pipe clamp 44 to pass through. Multiple connecting holes 121 are spaced apart along the length of the crossbar 12. In addition to the pipe clamp 44, binding wire or binding tape can also be used to directly bind the soil-inserting steel pipe 41 to the crossbar 12 through the connecting holes 121, thereby adjusting the spacing of the soil-inserting steel pipe 41. The side of the soil-inserting steel pipe 41 can be provided with a snap-fit ​​block. A slot adapted to the snap-fit ​​block is opened on the crossbar 12. The slot is spaced apart along the length of the crossbar 12. The detachable connection between the soil-inserting steel pipe 41 and the crossbar 12 is achieved by snap-fitting the snap-fit ​​block and the slot.

[0030] To adjust the soil penetration depth of the steel pipe 41 and ensure that the steel pipe 41 installed on the crossbar 12 moves up and down synchronously to achieve uniform depth of the fertilizer application holes, such as... Figure 7 As shown, vertical rods 13 are connected to both ends of the crossbar 12. The vertical rods 13 are fixed to the vehicle body, and the crossbar 12 is slidably mounted on the vertical rods 13 along their length. Specifically, vertical rods 13 are provided at both ends of the crossbar 12, and the crossbar 12 is slidably mounted on the vertical rods 13 along their length. Alternatively, vertically arranged grooves 131 can be provided on the vertical rods 13, and the crossbar 12 can be slidably mounted within these grooves. When the telescopic mechanism moves the crossbar 12 up and down... When moving, the crossbar 12 moves up and down along the slide groove 131 and is fixed by the corresponding locking device, thereby adjusting the soil penetration depth of the soil-inserting steel pipe 41; a gear and rack mechanism can also be set at the connection between the vertical bar 13 and the crossbar 12, and the crossbar 12 can be moved up and down by driving the gear and rack; multiple strip holes 532 that are adapted to the size of the crossbar 12 can also be set at intervals on the vertical bar 13, and the position of the crossbar 12 inserted into the vertical bar 13 can be adjusted according to the fertilization depth.

[0031] To prevent the winch 222 from being too high, which would cause excessive resistance during mixing and excessive pressure on the organic fertilizer, leading to clumping and blockage at the fertilizer outlet 21 or fertilizer discharge 34, the winch 222 is 2-3 cm high. Through multiple tests, the winch 222 is designed to mix the fertilizer while avoiding excessive resistance and pressure on the organic fertilizer, which would cause clumping and blockage at the fertilizer outlet 21 or fertilizer discharge 34.

[0032] To facilitate control over the amount of fertilizer applied and whether or not to apply fertilizer, such as Figure 4As shown, the ridge-mulch organic fertilizer strip applicator also includes a gate valve mechanism 5 for controlling fertilizer application, located between the fertilizer box 2 and the fertilizer application mechanism 3. The gate valve mechanism 5 includes an upper gate box 51 fixedly connected to the bottom of the fertilizer box 2, a lower gate box 52 fixedly connected to the top of the fertilizer application mechanism 3, and a gate plate 53 movably disposed between the upper gate box 51 and the lower gate box 52. The upper gate box 51 and the lower gate box 52 are bolted together. The upper gate box 51 has a hole with the same diameter as the fertilizer application hole 21 and is aligned with the fertilizer application hole 21. The first through hole 511, the lower plate 52 of the gate box has a second through hole 521 with the same diameter as the upper inlet hole 33 and aligned with the upper inlet hole 33, the upper surface of the lower plate 52 of the gate box has a frame-shaped protrusion 522 located around the second through hole 521, one end of the frame-shaped protrusion 522 has an opening 523 for the insertion of the gate piece 53; the gate piece 53 is inserted into the frame-shaped protrusion 522 to block the first through hole 511 and the second through hole 521, and one end of the gate piece 53 has a handle 531. Figure 1 , Figure 4 As shown, the upper gate box 51 is welded to the bottom of the fertilizer box 2, and the first through hole 511 of the upper gate box 51 is aligned with the lower fertilizer hole 21 of the fertilizer box 2. The lower gate box 52 is welded to the top of the lower fertilizer box 31, and the second through hole 521 of the lower gate box 52 is aligned with the upper fertilizer inlet hole 33 of the lower fertilizer box 31. The first through hole 511 of the upper gate box 51 and the second through hole 521 of the lower gate box 52 are aligned. Bolts are provided around the upper gate box 51 and the lower gate box 52 for connection to ensure the connection stability of the upper gate box 51 and the lower gate box 52. A gate plate 53 for blocking the first through hole 511 and the second through hole 521 is movably connected between the upper gate box 51 and the lower gate box 52. In order to limit the insertion distance of the gate plate 53 and provide the insertion space of the gate plate 53, the lower gate box 52 is provided with a gate plate located at the second through hole 511. A circumferential frame-shaped protrusion 522 is provided at one end for inserting the brake plate 53. The protrusion 522 can be directly welded to the lower plate 52 of the brake box using a wire rod or a steel sheet. To facilitate the control of the movement of the brake plate 53 between the upper plate 51 and the lower plate 52 of the brake box, a hand-held rod 531 is provided at one end of the brake plate 53. This allows the operator to hold the hand-held rod 531 to control the movement of the brake plate 53. The hand-held rod 531 can be directly welded to the brake plate 53, or a nut can be welded to the brake plate 53, and a screw rod can be used as the hand-held rod 531. The screw rod is screwed into the nut to set the hand-held rod 531 on the brake plate 53. The amount and timing of fertilizer application in the fertilizer box 2 are controlled by the gate valve mechanism 5 to ensure the fertilization effect.

[0033] To further ensure that the fertilizer in fertilizer tank 2 does not clump and cause blockage, and to ensure the installation stability of fertilizer tank 2, such as Figure 1 , Figure 3As shown, the rotary tillage and mulching machine's main beam 11 is also equipped with a hydraulic cylinder 14. The cylinder body 141 of the hydraulic cylinder 14 is mounted on the main beam 11. The telescopic end 142 of the hydraulic cylinder 14 is connected to the fertilizer box 2. The fertilizer box 2 has a hinge part 23 on the side away from the hydraulic cylinder 14. The hinge part 23 includes a support rod 232 vertically mounted on the main beam 11 and a hinge rod 231 mounted on the outside of the fertilizer box 2. The end of the hinge rod 231 away from the fertilizer box 2 is hinged to the top of the support rod 232. The rotary tillage and mulching machine's main beam 11... A hydraulic cylinder 14 is installed on the top of the fertilizer box 2. The end of the fertilizer box 2 away from the hydraulic cylinder 14 is provided with a hinge part 23 that is connected to the main beam 11 of the rotary tillage and mulching machine. The hinge rod 231 on the outside of the fertilizer box 2 is hinged to the support rod 232 on the main beam 11 of the rotary tillage and mulching machine. The extension end 142 of the hydraulic cylinder 14 drives the fertilizer box 2 to swing left and right, so that the fertilizer in the fertilizer box 2 shakes, ensuring that the fertilizer forms a hole-shaped frame when it falls naturally. The fertilizer collapses and falls due to the left and right swing of the fertilizer box 2 and the vibration generated by the operation of the main beam 11 of the rotary tillage and mulching machine.

[0034] To ensure that the first mixer 22 and the second mixer 32 operate synchronously and save power consumption, such as Figure 6 As shown, the drive mechanism 6 includes a motor 62 and a transmission mechanism 61 mounted on the main beam 11 of the rotary tillage and mulching machine. The transmission mechanism 61 includes a first gear 224 fixedly connected to the end of the first rotating shaft 221, a second gear 326 fixedly connected to the end of the second rotating shaft 321, a third gear 621 fixedly connected to the output end of the motor 62, and a gear set 611 mounted on the main beam 11 of the rotary tillage and mulching machine. The gear set 611 includes a gear shaft 612 fixedly connected to the bracket 143. A fourth gear 613, a fifth gear 614, and a third gear 621 are rotatably connected to the gear shaft 612 at intervals. A transmission chain 616 is provided between the fourth gear 613 and the first gear 224, between the fifth gear 614 and the second gear 326, and between the sixth gear 615 and the third gear 621. The drive mechanism 6 adopts a combination of the motor 62 and the transmission mechanism 61, which has a compact structure and high transmission efficiency. The first mixer 22 and the second mixer 32 can be operated synchronously through the transmission of gears and chains.

[0035] like Figure 1 , Figure 5 As shown, the fertilizer inlet pipe 35 is funnel-shaped. The funnel-shaped fertilizer inlet pipe 35 can increase the flow area of ​​organic fertilizer, reduce the risk of blockage during the fertilizer inlet process, and improve the fertilizer inlet efficiency.

[0036] In summary, during operation, the organic fertilizer strip applicator under the ridge film uses a motor 62 to drive the first mixer 22 and the second mixer 32 via a transmission mechanism 61 to mix the organic fertilizer in the fertilizer box 2 and the fertilizer inlet box 31. The operator controls the gate valve mechanism 5 to open the fertilizer inlet channel. The organic fertilizer enters the fertilizer inlet box 31 from the fertilizer inlet hole 21 of the fertilizer box 2 through the upper fertilizer inlet hole 33, then through the fertilizer outlet hole 34, the fertilizer inlet pipe 35, and the hose 351 into the soil inlet steel pipe 41, and finally into the soil. During operation, the telescopic mechanism can adjust the height of the crossbar 12 as needed, thereby adjusting the soil penetration depth of the soil inlet steel pipe 41. Simultaneously, the unblocking spring 325 can unblock the fertilizer inlet pipe 35 and the soil inlet steel pipe 41 in real time to prevent blockage.
