Description

Technical Field

[0001] This utility model relates to the field of soil turning structure technology, and in particular to an adaptive and extendable soil turning structure for land reclamation. Background Technology

[0002] In order to restore the land ecosystem, restore the environmental function, or transform abandoned and idle land into usable land and alleviate the pressure of land resource shortage, it is necessary to reclaim the land. Soil turning is an important means of soil improvement in land reclamation. Soil turning structure can be used to break up the soil compaction layer, increase soil aeration and water permeability, and create conditions for crop root growth and microbial activity. To address this, patent CN212970683U discloses a soil-turning device for mine land reclamation, including a connecting frame. The device further includes a soil-turning mechanism and a soil-crushing mechanism, with the connecting frame rotatably connected to both the soil-turning mechanism and the soil-crushing mechanism, which are arranged in parallel. This soil-turning device for mine land reclamation can both turn the soil and crush it, which is beneficial for subsequent planting and improves reclamation efficiency. While the aforementioned soil turning device for mine land reclamation can both turn and crush the soil during use, which is beneficial for subsequent planting and improves reclamation efficiency, it only achieves operation through a simple rotating connection between the connecting frame and the turning and crushing mechanisms. This makes it unable to cope with complex reclamation terrain with alternating pits and ridges. It cannot buffer impacts and avoid rigid collisions on ridges, nor can it actively sink and maintain depth on depressions, resulting in uneven turning depth and poor terrain adaptive extension adjustment effect, making it difficult to maintain the preset operating depth. Furthermore, during the turning and crushing process, soil and waste residue easily adhere to the surface of the operating components, causing blockages and requiring machine shutdown for cleaning, which reduces reclamation efficiency and affects the turning effect. Therefore, it is necessary to design an adaptive extension type soil turning structure for land reclamation. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive and extendable soil turning structure for land reclamation, in order to solve the defects of existing soil turning structures for land reclamation, such as poor terrain adaptive extension adjustment effect and easy clogging of turning components during the soil turning process.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adaptive and extendable soil-turning structure for land reclamation, including a main frame; The top of the main frame is fixed with an upper support, and the bottom of the upper support is flipped to connect with a lower support. An adaptive lifting extension component is evenly installed between the upper support and the lower support. The adaptive lifting extension component includes an upper connecting rod and a lower connecting rod that are movably connected to the upper support and the lower support, respectively. The bottom end of the upper connecting rod is fixed with a telescopic cylinder, and an output rod fixed to the lower connecting rod is slidably connected to the telescopic cylinder. A composite rubber spring is connected between the output rod and the telescopic cylinder. A viscous damping cylinder is fixed to the top end of the lower connecting rod, and a piston rod fixed to the upper connecting rod is provided at the output end of the viscous damping cylinder. The bottom of the lower support is movably connected to a hollow soil turning roller, and the inside of the hollow soil turning roller is suspended and fixed to the lower support with a spray pipe. An air compressor is installed at one end of the spray pipe.

[0005] Furthermore, both sides of the upper and lower connecting rods are provided with second damping shafts, and the upper and lower connecting rods are respectively connected to the upper and lower supports via the second damping shafts to form a flip connection.

[0006] Furthermore, the outer wall of the hollow soil turning roller is uniformly welded with crushing blades, and the crushing blades are uniformly provided with serrations.

[0007] Furthermore, the air compressor is fixed on the lower support, and the outer wall of the blow pipe is uniformly threaded with nozzles.

[0008] Furthermore, auxiliary casters are installed on both sides of one end of the main frame, and external screw holes are evenly provided on the bottom of the main frame.

[0009] Furthermore, a housing is provided on the side of the lower support away from the air compressor, and a servo motor is installed on the outer wall of the housing.

[0010] Furthermore, the output end of the servo motor is connected to a drive gear, and the bottom of the drive gear is meshed with a driven gear, with the hollow soil turning roller fixed at the middle position of the driven gear.

[0011] Furthermore, a first flip connecting arm and a second flip connecting arm are fixed sequentially on both sides of the lower support, and a first damping pivot is provided between the top of the first flip connecting arm and the second flip connecting arm and the upper support.

[0012] The advantages of the adaptive and extendable soil-turning structure for land reclamation provided by this utility model are as follows: Equipped with an adaptive lifting and extension assembly, the convex force of the raised terrain is transmitted to the lower support via the hollow turning roller. This causes the lower support to tilt upwards around the first and second damping shafts. The composite rubber spring contracts, the output rod slides upwards along the telescopic cylinder, and the piston rod of the viscous damping cylinder contracts synchronously, buffering the impact through damping force to avoid rigid structural collisions. Furthermore, in concave terrain, after the lower support loses support, the composite rubber spring releases its elastic potential energy, pushing the output rod to extend along the telescopic cylinder, causing the lower support to tilt downwards around the damping shaft. The hollow turning roller then sinks, and the viscous damping... The hydraulic cylinder provides smooth damping to prevent excessive tilling and achieves adaptive extension adjustment, ensuring that the hollow tilling roller always maintains the preset tilling depth. This adapts to the complex terrain of land reclamation with potholes and ridges, improving the tilling effect. Furthermore, during the tilling operation, the air compressor works continuously, delivering high-pressure gas to the inside of the spray pipe. The high-pressure gas is sprayed outward through nozzles evenly distributed on the outer wall of the spray pipe, directly acting on the inner wall of the hollow tilling roller and the surface of the crushing blade, promptly blowing off the adhering soil and waste, preventing the tilling components from clogging, and improving tilling efficiency. Equipped with a crushing blade, the hollow soil-turning roller is driven to rotate by a servo motor mounted on the outer wall of the machine box, in conjunction with the meshing transmission of the drive and driven gears. The power transmission is stable, ensuring uniform soil turning depth and providing good soil conditions for subsequent planting. Furthermore, the crushing blades uniformly welded to the outer wall of the hollow soil-turning roller have a serrated structure. Compared with ordinary soil-turning blades, the serrated design increases the soil cutting contact area and improves the crushing effect of hard soil and clump soil. Attached Figure Description

[0015] 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.

[0016] Please see Figures 1-5 The present invention provides an adaptive and extendable soil-turning structure for land reclamation, including a main frame 6.

[0017] Reference Figures 1-5 The top of the main frame 6 is fixed with an upper support 7, and the bottom of the upper support 7 is flipped to connect with a lower support 3. An adaptive lifting extension component 8 is evenly installed between the upper support 7 and the lower support 3. The adaptive lifting extension component 8 includes an upper connecting rod 801 and a lower connecting rod 805 that are respectively movably connected to the upper support 7 and the lower support 3. A telescopic cylinder 803 is fixed to the bottom end of the upper connecting rod 801, and an output rod 804 fixed to the lower connecting rod 805 is slidably connected to the telescopic cylinder 803. A composite rubber spring 802 is connected between the output rod 804 and the telescopic cylinder 803. A viscous damping cylinder 806 is fixed to the top end of the lower connecting rod 805, and a piston rod 807 fixed to the upper connecting rod 801 is provided at the output end of the viscous damping cylinder 806. The bottom of the lower support 3 is movably connected to a hollow soil turning roller 4, and the hollow soil turning roller 4 is suspended inside and fixed to the lower support 3 with a jet pipe 5. An air compressor 9 is installed at one end of the jet pipe 5. The air compressor 9 is fixed on the lower support 3, and the outer wall of the blow pipe 5 is uniformly threaded with nozzles 10; The lower support 3 has a first flip connecting arm 13 and a second flip connecting arm 14 fixed on both sides in sequence, and the top of the first flip connecting arm 13 and the second flip connecting arm 14 are provided with a first damping shaft 15 between them and the upper support 7.

[0018] In use, the upper support 7 and lower support 3, fixed inside the main frame 6, form a flip-connected structure through the first flip connecting arm 13, the second flip connecting arm 14, and the first damping rotating shaft 15. When the working surface encounters a raised terrain, the raised part generates an upward force on the hollow turning roller 4. This force is transmitted to the lower support 3 through the hollow turning roller 4, causing the lower support 3 to flip upward around the first damping rotating shaft 15 and the second damping rotating shaft 808. At this time, the composite rubber spring 802 in the adaptive lifting extension component 8 is compressed and contracted, and the output rod 804 slides upward along the telescopic cylinder 803. At the same time, the viscous damping cylinder 806 is activated. The stopper rod 807 retracts synchronously, buffering the impact of the protrusion through damping force to avoid rigid collision of the structure. When the working surface encounters a concave terrain, the lower support 3 loses ground support, the composite rubber spring 802 releases elastic potential energy, pushing the output rod 804 to extend downward along the telescopic cylinder 803, causing the lower support 3 to rotate downward around the damping axis, and the hollow soil turning roller 4 sinks accordingly, ensuring that the hollow soil turning roller 4 always maintains the preset soil turning depth. The viscous damping cylinder 806 provides stable damping in this process, avoiding the lower support 3 from sinking too quickly and causing excessive soil turning. Thus, it can achieve a better adaptive extension adjustment function according to the soil terrain.

[0019] With an external power supply, the air compressor 9 works continuously during the soil turning operation, delivering high-pressure gas to the inside of the spray pipe 5. The high-pressure gas is sprayed outward through the nozzles 10 evenly distributed on the outer wall of the spray pipe 5, directly acting on the inner wall of the hollow soil turning roller 4 and the surface of the crushing blade 16, promptly blowing off the adhering soil and waste residue, avoiding clogging of the soil turning components, and ensuring soil turning efficiency.

[0020] Reference Figures 1-4 Both sides of the upper connecting rod 801 and the lower connecting rod 805 are provided with a second damping shaft 808, and the upper connecting rod 801 and the lower connecting rod 805 are respectively connected to the upper support 7 and the lower support 3 through the second damping shaft 808. The outer wall of the hollow soil turning roller 4 is uniformly welded with a crushing blade 16, and the crushing blade 16 is uniformly provided with serrations. Auxiliary casters 17 are installed on both sides of one end of the main frame 6, and external screw holes are evenly provided on the bottom of the main frame 6. A housing 1 is provided on the side of the lower support 3 away from the air compressor 9, and a servo motor 2 is installed on the outer wall of the housing 1; The output end of the servo motor 2 is connected to the drive gear 11, and the bottom of the drive gear 11 is meshed with the driven gear 12. The hollow soil turning roller 4 is fixed at the middle position of the driven gear 12.

[0021] During use, the auxiliary casters 17 on both sides of one end of the main frame 6 facilitate the overall movement of the equipment and the adjustment of the working position. The external screw holes at the bottom of the main frame 6 can be quickly fixed with tractors and other traction equipment, improving adaptability.

[0022] When the external power supply is connected, the servo motor 2 on the outer wall of the housing 1 is started. Its output end drives the drive gear 11 to rotate, and drives the driven gear 12 to rotate through the gear meshing action. Since the hollow soil turning roller 4 is fixed in the middle position of the driven gear 12, it drives the hollow soil turning roller 4 to rotate synchronously. The crushing blade 16 welded on the outer wall of the hollow soil turning roller 4 rotates with the roller body, and uses the saw tooth structure to cut and crush the soil to complete the soil turning operation.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
