Description

Technical Field

[0001] This invention relates to the field of grassland improvement devices, specifically to a high-efficiency grassland improvement device and method. Background Technology

[0002] In the field of turfgrass improvement, traditional turfgrass improvement operations typically suffer from two major pain points: First, the application of amendments and turf aeration are independent processes, requiring multiple devices to complete the work in stages. This not only leads to low operational efficiency but also causes problems such as accumulation, blockage, and uneven distribution of amendments during delivery, resulting in localized waste or insufficient amendments and further reducing the quality of improvement. Second, traditional aeration equipment often uses a single rotating aeration structure, which makes the aeration tube prone to sticking and clogging with the soil. In addition, the small aeration size is not conducive to improving soil aeration, and the amendment cannot accurately penetrate into the aeration holes, affecting the improvement effect. To address these issues, we have introduced a highly efficient turfgrass improvement device and method. Summary of the Invention

[0012] Preferably, the top of the temporary storage cylinder is connected to a top connecting box, the top of the top connecting box is connected to the bottom slot at the bottom of the granular grass conditioner hopper, and the top connecting box is inclined backward.

[0013] The bottom of the uniformly distributed shell is connected to a bottom connecting box, the bottom of which is connected to the top of the uniformly distributed box, and the bottom of the uniformly distributed box has evenly distributed holes.

[0014] Preferably, the drive assembly includes a front rotating shaft rotatably connected inside the evenly distributed assembly, a driven bevel gear and a scraper on the front rotating shaft, and a driving bevel gear meshing with the driven bevel gear;

[0015] The scraper is located inside the temporary storage cylinder, and the driven bevel gear and the driving bevel gear are located inside the gearbox, with the driving bevel gear being driven by a reducer at the front end of the frame.

[0016] Preferably, the grass perforation assembly further includes a transmission box that extends rearward through both sides of the inner side of the housing;

[0017] The front shaft extends into the transmission box at both ends and is fixed with a drive drive wheel. The rear shaft extends into the transmission box at both ends and is fixed with a driven drive wheel. The transmission belt inside the transmission box is connected to the drive drive wheel and the driven drive wheel.

[0018] Preferably, the auxiliary limiting component includes a limiting plate passing through the middle of the rear rotating shaft, an annular limiting groove provided on both sides of the limiting plate, and abutment balls installed at both ends of the limiting plate;

[0019] The inner end of the outer rotating cylinder is open and inserted into the annular limiting groove.

[0020] Preferably, the inner rotating component includes an intermediate cylinder sleeved on the rear rotating shaft, support discs fixed at both ends of the intermediate cylinder, and sliding protrusions fixed at equal intervals on the outer sides of the support discs.

[0021] The sliding protrusion slides into the corresponding reserved groove, and an abutment ring is fixed on the inner support plate. The inner wall of the abutment ring is provided with arc-shaped grooves at equal intervals, and the abutment ball is in close contact with the inner wall of the abutment ring.

[0022] Several sets of return springs are distributed in a circular pattern at equal intervals on the inner wall of the outer rotating cylinder, and the return springs are fixed to the corresponding support plates.

[0024] This invention also provides an improvement method based on a high-efficiency grassland improvement device, specifically including the following steps:

[0025] S1. Drive the component to rotate, and distribute the granular grass conditioner evenly to the grass through the distribution component;

[0026] S2. At the same time, the drive component also drives the grass perforation component to rotate relative to the auxiliary limiting component;

[0027] S3, the auxiliary limiting component drives the inner rotating component to reciprocate within the outer rotating cylinder, thereby enabling the reciprocating movement of the perforating tube for grass perforation.

[0028] Compared with existing technologies, the advantages of this invention are: This invention enables a single power source to synchronously drive the distribution component and the grass aeration component, allowing the application of the amendment and the aeration operation to proceed simultaneously. Furthermore, it eliminates the need for multiple devices, significantly simplifying the workflow and improving operational efficiency.

[0029] This invention enables the perforated pipe to achieve a composite motion of "rotation and revolution + reciprocating axial movement". The reciprocating movement can clean the soil on the outer wall of the perforated pipe in real time, avoid adhesion and blockage, increase the perforation size, and improve soil aeration.

[0030] The invention features a front rotating shaft that drives a scraper to rotate, which can stir the amendment in the storage cylinder to prevent clumping and control the pushing flow rate. The flow guiding effect of the bottom connecting box and the uniform distribution holes at the bottom of the distribution box ensure that the amendment falls at a uniform flow rate, ensuring that the amendment is evenly distributed on the grass surface, improving the utilization efficiency of the amendment and avoiding resource waste.

[0050] 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.

[0051] Example:

[0052] Please see Figures 1-18 The present invention provides a technical solution:

[0053] A high-efficiency grassland improvement device includes a frame 1. A uniform distribution component 6 is fixed inside the front side of the frame 1. The uniform distribution component 6 includes a uniform distribution shell 601, a gearbox 602 disposed in the middle of the uniform distribution shell 601, temporary storage cylinders 603 disposed on both sides inside the uniform distribution shell 601, and a uniform distribution box 607 fixed at the bottom of the uniform distribution shell 601. A lubricating oil injection pipe 606 at the top of the gearbox 602 extends through the frame 1. A granular grassland conditioner hopper 3 is disposed at the top front side of the frame 1 and communicates with the uniform distribution component 6. The top of the temporary storage cylinder 603 communicates with the bottom of the granular grassland conditioner hopper 3, and the bottom of the temporary storage cylinder 603 communicates with the top of the uniform distribution box 607.

[0054] The top of the temporary storage cylinder 603 is connected to a top connecting box 605. The top of the top connecting box 605 is connected to the bottom slot 13 at the bottom of the granular grass conditioner hopper 3, and the top connecting box 605 is tilted backward.

[0055] The bottom of the uniformly distributed housing 601 is connected to a bottom connecting box 604, the bottom of the bottom connecting box 604 is connected to the top of the uniformly distributed box 607, and the bottom of the uniformly distributed box 607 has uniformly distributed holes 608 evenly distributed.

[0056] The top of the top connecting box 605 is connected to the bottom slot 13 of the bottom of the granular grass amendment hopper 3, and is set to tilt backward. This tilted structure can guide the amendment to slide down smoothly and avoid the amendment from accumulating and blocking at the outlet of the granular grass amendment hopper 3. At the same time, the top connecting box 605 realizes the smooth connection between the granular grass amendment hopper 3 and the two sets of temporary storage cylinders 603, so that the amendment can be evenly distributed to the temporary storage cylinders 603 on both sides, laying the foundation for subsequent uniform distribution operations.

[0057] The bottom connecting box 604 facilitates the transition between the temporary storage cylinder 603 and the distribution box 607, allowing for the convergence and guidance of the amendment pushed by the scraper 9, preventing the amendment from scattering at the bottom outlet of the temporary storage cylinder 603. The evenly distributed distribution holes 608 at the bottom of the distribution box 607 can transform the converged amendment into a uniform flow, ensuring that the amendment is evenly distributed on the grass surface, avoiding excessive or insufficient amendment in certain areas, and improving the amendment effect.

[0058] The rear side of the frame 1 is rotatably connected to a grass aeration component 7. Several sets of soft curtains 14 are evenly spaced at the bottom rear end of the frame 1. The sets of soft curtains 14 at the bottom rear end of the frame 1 can cover the area where aeration and soil amendment have been completed, to prevent dust from spreading during the operation, and to prevent external debris (such as weeds and stones) from entering the aeration holes, thus ensuring the contact effect between the soil amendment and the soil and improving the quality of soil amendment.

[0059] The front end of the frame 1 is also equipped with a connecting frame 2. The connecting frame 2 at the front end of the frame 1 provides a stable interface for the connection between the device and the external traction equipment, ensuring that the device can move smoothly with the traction equipment, avoiding deviation during operation, ensuring the uniformity of the modifier distribution range and the regularity of the drilling trajectory, and improving the overall operation effect.

[0060] The drive component inside the uniform distribution component 6 rotates to achieve uniform distribution of the granular grass conditioner. At the same time, it also drives the grass aeration component 7 to rotate to perform aeration on the grass. The uniform distribution housing 601 encapsulates the core components of the uniform distribution component, such as the gearbox 602 and the temporary storage cylinder 603. The transmission box 701 encapsulates the transmission components, such as the active transmission wheel 8, the driven transmission wheel 706, and the transmission belt 705. This effectively prevents dust, moisture, weeds, and other elements in the grass environment from corroding the internal components, while also preventing interference with the external environment during component operation, thus improving the operational stability and safety of the device.

[0061] The drive assembly includes a front rotating shaft 12 rotatably connected inside the distribution assembly 6, a driven bevel gear 11 and a scraper 9 on the front rotating shaft 12, and a driving bevel gear 10 meshing with the driven bevel gear 11. The scraper 9 rotates synchronously with the front rotating shaft 12. The rotating scraper 9 can stir and push the modifier in the temporary storage cylinder 603. On the one hand, it can prevent the modifier from clumping and blocking in the temporary storage cylinder 603. On the other hand, it can control the pushing flow of the modifier to ensure that the modifier continuously and stably enters the distribution box 607 and ensure the continuity of the distribution operation.

[0062] The scraper 9 is located inside the temporary storage cylinder 603, and the driven bevel gear 11 and the driving bevel gear 10 are located inside the gearbox 602. The driving bevel gear 10 is driven by the reducer 4 at the front end of the frame 1. The input end of the reducer 4 is connected to the drive shaft 5.

[0063] The meshing drive of the driving bevel gear 10 and the driven bevel gear 11 (within the gearbox 602) converts the horizontal power transmitted by the reducer 4 into the axial rotational power of the front shaft 12. The power transmission direction conversion is precise, the meshing transmission has high transmission efficiency and stable torque transmission. At the same time, the gearbox 602 can seal and protect the two bevel gears to prevent dust and moisture in the grassland working environment from corroding the gears and extend the service life of the transmission components. Moreover, a single power source drives the scraper 9 and the driving drive wheel 8 to rotate simultaneously through this gear meshing mechanism, realizing the split utilization of power. There is no need to set up an additional independent power source, which simplifies the device structure and reduces the equipment manufacturing cost and maintenance difficulty.

[0064] The reducer 4 can reduce the speed and increase the torque of the externally input power, so that the drive bevel gear 10 can obtain the appropriate speed and torque. This satisfies the speed requirement of the scraper 9 to smoothly push the amendment, and also provides sufficient drilling torque for the grass aeration assembly 7, avoiding operation failure due to mismatch of power parameters and improving the rationality of power utilization.

[0065] The lawn aeration assembly 7 includes an outer rotating cylinder 702 symmetrically fixed on both sides of a rear rotating shaft 710, an inner rotating component slidingly connected inside the outer rotating cylinder 702, and an auxiliary limiting component connecting the two sets of outer rotating cylinders 702. The perforation tube 703 on the inner rotating component extends through the reserved groove 711 on the outer rotating cylinder 702. The lawn aeration assembly 7 also includes a transmission box 701 extending rearward through both sides of the interior of the housing 601. The two ends of the front rotating shaft 12 extend into the transmission box 701 and are fixed with a drive transmission wheel 8. The two ends of the rear rotating shaft 710 extend into the transmission box 701 and are fixed with a driven transmission wheel 706. The transmission belt 705 inside the transmission box 701 is connected to the drive transmission wheel 8 and the driven transmission wheel 706.

[0066] The transmission connection between the front rotating shaft 12, the driving drive wheel 8, the drive belt 705, the driven drive wheel 706, and the rear rotating shaft 710 achieves power linkage between the evenly distributed component 6 and the grass perforation component 7 through belt drive. The belt drive has the characteristics of buffering and absorbing vibration, which can alleviate the impact of equipment vibration caused by uneven grass on power transmission and ensure the smoothness of the transmission process. At the same time, the transmission box 701 encloses and protects this group of transmission components to prevent grass debris from getting entangled or corroding the drive wheel and drive belt 705, ensuring the continuity of power transmission. In addition, the transmission structure has a compact layout, which can effectively utilize the internal space of the frame 1 and make the overall structure of the device more regular.

[0067] The auxiliary limiting components include a limiting disk 704 that passes through the middle of the rear rotating shaft 710, annular limiting grooves 718 provided on both sides of the limiting disk 704, and abutment balls 719 installed at both ends of the limiting disk 704. The inner end of the outer rotating cylinder 702 is open and inserted into the annular limiting groove 718.

[0068] The inner rotating component includes an intermediate cylinder 714 sleeved on the rear rotating shaft 710, support plates 712 fixed at both ends of the intermediate cylinder 714, and sliding protrusions 709 fixed at equal intervals on the outer sides of the support plates 712. The sliding protrusions 709 slide in the corresponding reserved grooves 711. An abutment ring 716 is fixed on the inner support plate 712. The inner wall of the abutment ring 716 is provided with arc-shaped grooves 717 at equal intervals. The abutment ball 719 is close to the inner wall of the abutment ring 716. The inner rotating component slides in the reserved grooves 711 of the outer rotating cylinder 702 through the sliding protrusions 709, so that the inner rotating component can move back and forth along the axial direction of the outer rotating cylinder 702 while rotating synchronously with the outer rotating cylinder 702. This realizes the composite motion of "revolution + reciprocating movement" of the perforated tube 703, which not only improves the perforation efficiency, but also cleans the soil on the outer wall of the perforated tube 703 through reciprocating movement, avoids adhesion and blockage, and ensures the perforation quality.

[0069] The limiting plate 704 has symmetrical hemispherical inner grooves 7043 for placing the abutment ball 719 on both side walls. Two sets of circular limiting covers 7041 are also symmetrically fixed on both side walls of the limiting plate 704. The circular limiting cover 7041 has an arc-shaped through hole 7042, and the outer end of the abutment ball 719 extends out through the arc-shaped through hole 7042.

[0070] The circular limiting cover 7041 and the arc-shaped through hole 7042 thereon serve to limit the abutment ball 719. When the abutment ball 719 rolls in the hemispherical inner groove 7043, the abutment ball 719 will not fall off.

[0071] Several sets of return springs 713 are distributed in a circular pattern at equal intervals on the inner wall of the outer rotating cylinder 702, and the return springs 713 are fixed to the corresponding support plates 712.

[0072] The return spring 713 provides elastic power for the reverse reset of the inner rotating part, ensuring that after the abutment ball 719 slides out of the arc groove 717, the inner rotating part can be reset quickly and smoothly, making the reciprocating motion of the inner rotating part more regular, ensuring the stability of the drilling rhythm of the punch tube 703, and improving the uniformity of the drilling operation.

[0073] The top of the limiting plate 704 is connected to the fixing plate 708 by the L-shaped frame 707. The fixing plate 708 is installed on the top of the transmission box 701. The outer side of the intermediate cylinder 714 is fixed to the inner wall of the sliding protrusion 709 by the support arm 715. The perforated tube 703 is fixed at equal intervals on the corresponding sliding protrusion 709.

[0074] The support arm 715 can enhance the connection strength between the sliding protrusion 709 and the intermediate cylinder 714, and prevent the sliding protrusion 709 from deforming or breaking due to excessive force when driving the perforated tube 703 to make holes, thereby improving the structural stability and load-bearing capacity of the inner rotating part.

[0075] The limiting plate 704 is fixed to the top of the transmission box 701 by the L-shaped frame 707 and the fixing plate 708, thus achieving self-fixation. Its annular limiting groove 718 forms a rotation limit for the inner end of the outer rotating cylinder 702, preventing axial displacement when the outer rotating cylinder 702 rotates and ensuring rotational stability. The abutment ball 719 cooperates with the arc-shaped groove 717 on the inner wall of the abutment ring 716 to convert the rotation of the outer rotating cylinder 702 into the reciprocating axial power of the inner rotating component. This eliminates the need for an additional reciprocating drive mechanism, simplifying the structure of the drilling assembly and reducing energy consumption. At the same time, the rolling contact between the abutment ball 719 and the abutment ring 716 reduces friction loss and extends the service life of the components. When the grass drilling assembly 7 rotates, the auxiliary limiting component drives the inner rotating component to reciprocate within the outer rotating cylinder 702, realizing the grass drilling by the reciprocating movement of the drilling tube 703.

[0076] This invention also provides an improvement method based on a high-efficiency grassland improvement device, specifically including the following steps:

[0077] S1. Drive the component to rotate, and distribute the granular grass conditioner evenly to the grass through the distribution component 6.

[0078] S2. At the same time, the drive component also drives the grass perforation component 7 to rotate relative to the auxiliary limiting component;

[0079] S3, the auxiliary limiting component drives the inner rotating component to reciprocate within the outer rotating cylinder 702, thereby realizing the reciprocating movement of the perforating tube 703 for grass perforation.

[0080] Specifically, when using it:

[0081] External power (the onboard power take-off shaft at the rear of the tractor) is transmitted to the reducer 4 through the drive shaft 5. After the reducer 4 reduces the speed and increases the torque, it drives the drive bevel gear 10 to rotate.

[0082] The driving bevel gear 10 meshes with the driven bevel gear 11 in the gearbox 602, transmitting power to the front rotating shaft 12, enabling the front rotating shaft 12 to rotate stably, thus completing the initial transmission and conversion of power.

[0083] Meanwhile, the active drive wheels 8 at both ends of the front shaft 12 are connected to the driven drive wheels 706 at both ends of the rear shaft 710 via the drive belt 705 in the transmission box 701, which transmits power from the distribution component 6 to the grass aeration component 7, providing a power foundation for the subsequent simultaneous operation of two tasks.

[0084] Synchronous job execution phase:

[0085] 1. Uniform distribution of granular lawn conditioner: The granular lawn conditioner is pre-poured into the granular lawn conditioner hopper 3, and the conditioner enters the top connecting box 605 through the bottom groove 13 at the bottom of the granular lawn conditioner hopper 3.

[0086] Because the top connecting box 605 is tilted backward, the modifier flows smoothly into the temporary storage cylinder 603 under the action of gravity and tilting guidance to complete the temporary storage.

[0087] When the front rotating shaft 12 rotates, it drives the scraper 9 on its surface to rotate synchronously. During the rotation of the scraper 9 in the temporary storage cylinder 603, it pushes the temporarily stored improver to the bottom connecting box 604. After being guided by the bottom connecting box 604, it enters the uniform distribution box 607.

[0088] Finally, the amendment falls onto the grass surface at a uniform flow rate through the evenly distributed holes 608 at the bottom of the distribution box 607, completing the uniform distribution of the amendment.

[0089] 2. Grassland aeration operation: The power transmitted by the front rotating shaft 12 drives the rear rotating shaft 710 to rotate, and the rear rotating shaft 710 drives the outer rotating cylinders 702 on both sides to rotate synchronously.

[0090] During the rotation of the outer rotating cylinder 702, the inner rotating part on its inner side rotates outward. At the same time, the limiting disk 704 forms a rotation limit on the inner end of the outer rotating cylinder 702 through the annular limiting groove 718, ensuring that the rotation trajectory of the outer rotating cylinder 702 is stable.

[0091] During this process, the abutting balls 719 at both ends of the limiting disk 704 slide close to the inner wall of the abutting ring 716. When the abutting balls 719 slide into the arc-shaped groove 717 on the inner wall of the abutting ring 716, they will generate a lateral thrust on the abutting ring 716, pushing the inner rotating part to move unidirectionally along the axial direction of the outer rotating cylinder 702.

[0092] When the ball 719 slides out of the arc-shaped groove 717, the return spring 713 on the inner wall of the outer rotating cylinder 702 releases its elastic potential energy, pulling the support plate 712 to drive the inner rotating component to return to its original position.

[0093] The above process is repeated, causing the inner rotating part to reciprocate axially along the reserved groove 711 of the outer rotating cylinder 702 via the sliding protrusion 709.

[0094] Since the perforating tube 703 is fixed on the sliding protrusion 709 and extends through the reserved groove 711, the perforating tube 703 achieves a composite motion of "rotation and revolution + reciprocating axial movement" with the sliding protrusion 709. During the rotation, it is inserted into the grass to complete the perforation. The reciprocating movement can prevent the perforating tube 703 from sticking too much to the grass soil, ensuring smooth perforation, increasing the perforation size, and making it easier for the soil conditioner mixed with rainwater to penetrate into the soil.

[0095] (III) Post-operation limit protection stage:

[0096] During the operation of the device, several sets of soft curtains 14 at the bottom rear end of the frame 1 reduce the dust loss of the modifier; the connecting frame 2 at the front end of the frame 1 can realize the stable connection between the device and the traction equipment (such as a tractor), ensuring that the whole device moves smoothly with the traction equipment and ensuring the regularity of the operation trajectory.

[0097] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
