Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, specifically to an adjustable transplanting seedling root soil stabilization device. Background Technology

[0002] When transplanting seedlings, ensuring that the soil around the roots is stable and in close contact with the root system is key to improving the survival rate of seedlings and promoting early growth. Traditional soil stabilization operations mostly rely on manual tamping or simple tools for compaction. In order to improve the efficiency and quality of operations, existing technologies have developed methods for stabilizing the soil around the roots using mechanized devices.

[0003] Currently, the most common mechanized soil stabilization method is to use a compaction roller to roll and compact the backfill soil in the seedling hole. However, during the compaction process, hard debris such as gravel mixed in the soil, uncleaned native plant roots (tree roots), and the thick root system (stem-like materials) of the transplanted seedlings can easily cause abrasions, scratches, or even structural damage to the surface of the compaction roller. It is difficult to prevent tree roots and stem-like materials from affecting the compaction effect of the roller, and it is also difficult to improve the protection of the roller. This needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable root stabilization device for transplanted seedlings, which has the advantages of stable structure, flexible adjustment and effective protection of root system, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable transplanter root stabilization device includes a mobile vehicle, rotating rollers rotatably mounted on the inner walls of both sides of the mobile vehicle, pressure rollers fixed to the outer peripheral walls of the rotating rollers near the edges of both ends, two ear plates fixed to one end of the mobile vehicle, a fixed rod fixed between the two ear plates, a second fixed block bolted to the fixed rod, a protective mechanism on the second fixed block, a hinge seat on the protective mechanism, rotating blocks rotatably mounted on the inner walls of both sides of the hinge seat, a first blocking mechanism between the two rotating blocks, a fixed platform fixed to the mobile vehicle, and a drive mechanism on the fixed platform for driving the rotating rollers to rotate.

[0007] A second blocking mechanism is provided on the fixed rod.

[0008] Preferably, the protective mechanism includes a vertical block and a protective plate. The vertical block is fixedly connected to the end of the second fixed block away from the moving vehicle. The protective plate is installed on the vertical block by bolts and nuts. The hinge is fixedly connected to the side wall of the protective plate.

[0009] It is worth noting that the protective mechanism, through the bolted connection between the uprights and the protective plate, enables quick disassembly and installation, facilitating flexible adjustment according to the root size of the transplanted seedlings. This effectively isolates the direct impact of mechanical parts on the root system during soil stabilization, preventing root damage. The uprights, acting as stable supports, ensure the positional stability of the protective plate during operation, avoiding displacement caused by soil resistance or equipment vibration, thus improving the overall reliability of the device. The hinge is fixed to the side wall of the protective plate, providing a precise rotation base for the rotating block, enabling the first blocking mechanism to operate smoothly. Together with the protective plate, it forms a multi-level protection, optimizing the uniformity and compactness of root soil stabilization.

[0010] Preferably, the top surface of the rotating block is U-shaped, and the first blocking mechanism includes a groove extending through both sides of the rotating block, an insert plate slidably disposed on the inner wall of the groove on the two rotating blocks, a stop block fixed to the end of the insert plate away from the moving vehicle, two slots extending through the upper end of the insert plate, an insert block inserted into the inner wall of the slot, and a handle fixed to the upper end of the insert block, with the two sides of the insert block and the two sides of the inner wall of the rotating block in contact.

[0011] It is worth noting that the U-shaped planar design of the rotating block allows the insert plate of the first blocking mechanism to slide smoothly in the groove, providing a stable guiding effect and preventing the insert plate from shaking or getting stuck during operation. This ensures that the blocking effect of the block on the soil is uniform and reliable. The two sides of the insert plate are tightly fitted to the two sides of the inner wall of the rotating block, which enhances the structural rigidity of the connection and reduces the risk of loosening caused by gaps. This effectively disperses soil pressure when stabilizing the soil and avoids local stress concentration that could cause wear to the device.

[0012] Preferably, the upper and lower ends of the insert plate are fixedly connected to a fixing frame, with the end of the fixing frame closer to the moving vehicle and the end of the rotating block away from the moving vehicle fitting together.

[0013] It is worth noting that the fixed frame design enhances the overall structural strength of the insert plate, preventing it from being deformed by stress during long-term use and affecting its blocking function. At the same time, the fit between the fixed frame and the end of the rotating block ensures the alignment accuracy of the insert plate during sliding, reducing friction loss. This fit structure forms an effective mechanical limit, preventing the insert plate from overextending or retracting, ensuring that the stop block works stably in the preset position, thereby maintaining a consistent blocking force during soil stabilization and improving the uniformity of soil compaction.

[0014] Preferably, the first blocking mechanism further includes a threaded column fixed to the inner wall of the groove, a turntable sleeved on the outer peripheral wall of the threaded column, two first nuts threaded on the outer peripheral wall of the threaded column, and a second nut threaded on the outer peripheral wall of the threaded column. The ends of the two first nuts that are close to each other are in contact with the two sides of the rotating block, and the end of the second nut that is close to the rotating block is in contact with the end of the fixed frame that is away from the rotating block.

[0015] It is worth noting that the engagement of the threaded post and the nut provides an adjustable locking mechanism. By rotating the first and second nuts, the fixed position of the insert plate within the groove can be precisely controlled, thereby enabling fine-tuning of the block spacing to accommodate the soil stabilization needs of transplanted seedlings of different diameters. The two first nuts fit snugly against the two sides of the rotating block, ensuring the threaded post is stably fixed axially and preventing it from loosening or shifting during operation, thus improving the overall rigidity of the first blocking mechanism. The fit between the second nut and the fixing frame enhances the end-fixing effect of the insert plate, forming a double locking mechanism that maintains structural stability under soil pressure. The design of the turntable facing the pressure roller improves the protection of the pressure roller, and because the turntable can rotate, it can block the impact pressure from debris.

[0016] Preferably, the outer peripheral wall of the threaded column fits into the inner wall of the fixed frame, and there is a gap between the two sides of the turntable and the insert plate.

[0017] It is worth noting that the fitting design between the outer peripheral wall of the threaded column and the inner wall of the fixed frame provides additional guidance and support, reduces the radial sway of the fixed frame when under force, ensures that the insert plate maintains linear motion during sliding, and improves the motion accuracy and reliability of the blocking mechanism.

[0018] Preferably, the drive mechanism includes a motor fixed to both sides of the fixed platform, a first sprocket fixed to the output shaft of the motor, a second sprocket fixed to the outer peripheral wall of the rotating shaft on both sides of the roller, and a chain simultaneously mounted on the first sprocket and the second sprocket, wherein the first sprocket and the second sprocket are rotatably connected by the chain.

[0019] It is worth noting that the drive mechanism adopts a transmission method of motor, sprocket and chain, which provides stable and efficient power transmission, ensuring uniform torque when the roller drives the pressure roller to rotate, thereby achieving uniform soil compaction and avoiding local pressure damage to the roots of transplanted seedlings. The chain drive has high load-bearing capacity and reliability, adapts to the variable load in field operations, and reduces the risk of slippage or breakage.

[0020] Preferably, the second blocking mechanism includes a first fixing block fixed to the outer peripheral wall of the fixing rod, a horizontal block fixed to one end of the first fixing block near the moving vehicle, and a plurality of rubber pillars fixed to the lower end of the horizontal block.

[0021] It is worth noting that the second blocking mechanism is fixed to the fixed rod through the first fixing block, providing an additional soil blocking layer. The elastic design of the rubber column can buffer the soil impact, prevent soil splashing or loss during the soil stabilization process, and enhance the wrapping and protection of the roots. The horizontal block, as a support base, disperses the pressure borne by the rubber column and improves the durability of the overall structure. At the same time, the multiple rubber columns are evenly arranged to ensure the continuity and consistency of the blocking effect, adapting to the soil stabilization needs under different terrain conditions.

[0022] Preferably, the turntable in the first blocking mechanism is positioned directly opposite the pressure roller, and the turntable is rotatably fitted onto the outer peripheral wall of the threaded column.

[0023] It is worth noting that the turntable in the first blocking mechanism is positioned directly opposite the pressure roller, and the turntable is rotatably fitted onto the outer peripheral wall of the threaded column. This design ensures that the turntable is always facing the forward direction of the pressure roller during operation, actively contacting and removing hard debris such as gravel and tree roots mixed in the soil, preventing them from directly impacting the surface of the pressure roller. At the same time, the rotatable nature of the turntable allows it to rotate flexibly when subjected to lateral impacts, converting the impact force of the debris into rotational kinetic energy, thereby effectively reducing damage and scratches to the pressure roller, significantly improving the protection effect on the pressure roller, and extending the service life of the device.

[0024] Preferably, the multiple rubber columns in the second blocking mechanism are evenly spaced along the length of the transverse block.

[0025] It is worth noting that the multiple rubber columns in the second blocking mechanism are evenly spaced along the length of the horizontal block. The evenly spaced rubber columns can form a continuous and consistent buffer barrier when the pressure roller is working. Each rubber column independently bears the local soil impact, avoiding stress concentration. At the same time, the even arrangement ensures the uniformity of the soil blocking effect throughout the entire length of the horizontal block, preventing local soil splashing or loss, thereby enhancing the wrapping and compaction uniformity of the soil around the roots, and further improving the soil fixation quality of the transplanted seedling roots.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. The removable protective plate in the protective mechanism is bolted to the upright block, which can flexibly adjust the protection range according to the size of the transplanted seedling roots. During the compaction process, it isolates the mechanical parts from direct impact on the root system and prevents root damage. At the same time, the turntable of the first blocking mechanism is facing the pressure roller and can rotate. When the pressure roller is working, it actively blocks hard debris such as gravel and tree roots in the soil to avoid them hitting the surface of the pressure roller, thereby reducing bruising and scratches and improving the protection effect of the pressure roller.

[0028] 2. The drive mechanism stably drives the rotating roller and pressure roller to rotate via a motor, sprocket, and chain, achieving uniform compaction of the soil. The insert plate of the first blocking mechanism is quickly fixed to the rotating block by threaded post and nut, making the block an adjustable barrier. Combined with the U-shaped guide design of the rotating block, it can ensure stable sliding of the insert plate to adapt to different root sizes. The rubber post of the second blocking mechanism buffers the soil impact and prevents soil splashing or loss. These parts work together to form multi-level protection during the compaction process, which not only avoids hard debris from affecting the compaction effect, but also enhances the wrapping and compaction of the soil around the roots.

[0029] 3. The overall structure features an adjustable design, such as quick disassembly and assembly of the protective plate, fine adjustment of the spacing between the blocks, and elastic arrangement of the rubber columns, which improves the applicability and reliability of the device. This device not only effectively prevents damage to the pressure rollers but also optimizes the uniformity of soil stabilization, thereby helping to improve the survival rate and initial growth quality of transplanted seedlings.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To address the problems of existing pressure roller-type soil stabilization devices being easily damaged by hard debris in the soil and being difficult to protect, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-7 ;

[0040] An adjustable transplanter root stabilization device includes a mobile cart 1, rotating rollers 2 rotatably mounted on the inner walls of both sides of the mobile cart 1, pressure rollers 3 fixed to the outer peripheral wall of the rotating rollers 2 near the edges of both ends, two ear plates 4 fixed to one end of the mobile cart 1, a fixing rod 5 fixed between the two ear plates 4, a second fixing block 6 bolted to the fixing rod 5, a protective mechanism set on the second fixing block 6, a hinge seat 7 set on the protective mechanism, rotating blocks 8 rotatably mounted on the inner walls of both sides of the hinge seat 7, a first blocking mechanism set between the two rotating blocks 8, a fixed platform 9 fixed to the mobile cart 1, and a drive mechanism set on the fixed platform 9 for driving the rotating rollers 2 to rotate.

[0041] A second blocking mechanism is provided on the fixed rod 5.

[0042] When in use, the protective mechanism is installed on the second fixed block 6, and the first blocking mechanism is installed between the two rotating blocks 8. When the device is turned on, the first blocking mechanism and the second blocking mechanism can be used to move away debris such as branches to avoid impacting the pressure roller 3, thus protecting the pressure roller 3.

[0043] In this embodiment, specifically: the protective mechanism includes a vertical block 61 and a protective plate 62. The end of the second fixed block 6 away from the mobile vehicle 1 is fixedly connected to the vertical block 61. The protective plate 62 is installed on the vertical block 61 by bolts and nuts. The hinge seat 7 is fixedly connected to the side wall of the protective plate 62.

[0044] In this embodiment, specifically: the top surface of the rotating block 8 is U-shaped, and the first blocking mechanism includes a groove 81 that passes through both sides of the rotating block 8, an insert plate 82 that slides on the inner wall of the groove 81 on the two rotating blocks 8, a stop block 83 that is fixed to the end of the insert plate 82 away from the moving vehicle 1, two slots 88 that pass through the upper end of the insert plate 82, an insert block 89 that is inserted into the inner wall of the slot 88, and a handle 810 that is fixed to the upper end of the insert block 89. The two sides of the insert block 89 are in contact with the two sides of the inner wall of the rotating block 8.

[0045] In this embodiment, specifically: the upper and lower ends of the insert plate 82 are fixedly connected to a fixing frame 811, and the end of the fixing frame 811 close to the moving vehicle 1 and the end of the rotating block 8 away from the moving vehicle 1 are attached.

[0046] In this embodiment, specifically: the first blocking mechanism further includes a threaded post 84 fixed to the inner wall of the groove 81, a turntable 85 sleeved on the outer peripheral wall of the threaded post 84, two first nuts 86 threaded on the outer peripheral wall of the threaded post 84, and a second nut 87 threaded on the outer peripheral wall of the threaded post 84. The ends of the two first nuts 86 that are close to each other are in contact with the two sides of the rotating block 8, and the end of the second nut 87 that is close to the rotating block 8 is in contact with the end of the fixed frame 811 that is away from the rotating block 8.

[0047] In this embodiment, specifically: the outer peripheral wall of the threaded column 84 and the inner wall of the fixing frame 811 are fitted together, and there is a gap between the two sides of the turntable 85 and the insert plate 82.

[0048] In this embodiment, specifically: the driving mechanism includes a motor 91 fixed to both sides of the fixed platform 9, a first sprocket 92 fixed to the output shaft of the motor 91, a second sprocket 94 fixed to the outer peripheral wall of the rotating shaft on both sides of the rotating roller 2, and a chain 93 simultaneously installed on the first sprocket 92 and the second sprocket 94. The first sprocket 92 and the second sprocket 94 are rotatably connected by the chain 93.

[0049] In this embodiment, specifically: the second blocking mechanism includes a first fixing block 51 fixed to the outer peripheral wall of the fixing rod 5, a horizontal block 52 fixed to one end of the first fixing block 51 near the moving vehicle 1, and a plurality of rubber pillars 53 fixed to the lower end of the horizontal block 52.

[0050] In this embodiment, specifically: the turntable 85 in the first blocking mechanism is positioned directly opposite the pressure roller 3, and the turntable 85 is rotatably fitted onto the outer peripheral wall of the threaded column 84.

[0051] In this embodiment, specifically: multiple rubber columns 53 in the second blocking mechanism are evenly spaced along the length of the horizontal block 52.

[0052] Working principle: When in use, first, according to the size of the root of the seedling to be transplanted, install the protective plate 62 of the corresponding width on the upright block 61 with bolts and nuts to flexibly adjust the protection range;

[0053] Then, the motor 91 on the fixed platform 9 is started. The output shaft of the motor 91 drives the first sprocket 92 to rotate, which in turn drives the second sprocket 94 and the rotating roller 2 fixed thereto to rotate through the chain 93. This causes the pressure rollers 3 fixed at both ends of the rotating roller 2 to rotate synchronously, so as to achieve uniform compaction of the soil around the roots of the seedlings.

[0054] During this process, the rotating block 8 installed on the hinge seat 7 on the side wall of the protective plate 62 and the first blocking mechanism therebetween move accordingly. The U-shaped surface of the rotating block 8 provides a stable sliding guide for the insert plate 82. The operator can insert or remove the insert block 89 into or out of the slot 88 on the insert plate 82 by using the handle 810 to quickly install and remove the insert plate 82 and the stop block 83 fixed at one end. Then, by tightening or loosening the first nut 86 and the second nut 87 on the threaded column 84, the lateral position of the insert plate 82 can be adjusted and fixed, so that the stop block 83 forms an adjustable-spacing barrier.

[0055] When the pressure roller 3 rolls and presses, the turntable 85 facing the pressure roller 3 can rotate freely, actively removing hard debris such as gravel and tree roots in the soil to prevent them from directly hitting the surface of the pressure roller 3 and avoiding damage or scratches.

[0056] Meanwhile, in the second blocking mechanism installed on the fixed rod 5, multiple rubber columns 53 continuously contact and buffer the soil during the compaction process, effectively suppressing soil splashing and loss;

[0057] With the coordinated operation of all mechanisms, the pressure roller 3 compacts the soil around the roots under the stable power provided by the drive mechanism. The protective plate 62 isolates the direct impact of the mechanical parts on the roots. The first blocking mechanism actively removes hard debris, and the second blocking mechanism buffers and maintains the soil position. Thus, while achieving uniform soil compaction, a multi-level protection is formed for the pressure roller 3, which not only protects the pressure roller 3 from damage, but also enhances the tightness of the soil covering the roots, ultimately improving the survival rate and initial growth quality of the transplanted seedlings.
