Description

TECHNICAL FIELD

[0001] The utility model relates to land leveling technical field, specifically point to a land restoration leveling device. BACKGROUND

[0002] In the field of land restoration, land leveling and compaction are the core links in the restoration process, aiming to improve soil structure, improve land use efficiency and provide a good foundation for subsequent planting or construction. Currently, rollers are commonly used in land restoration to compact and level the soil. The roller can compact loose soil through its own weight and rolling action, restoring the land surface to a level state. This method is widely used in land restoration, agricultural development and engineering construction due to its simple operation and significant effect.

[0003] However, due to the adhesion of the soil, part of the soil is easily attached to the surface of the roller during the rolling and compaction process. As the operation continues, the soil attached to the roller gradually accumulates, which not only increases the burden of the roller, but also may cause the rotation to be blocked, and even reduce the operation quality of the roller for land leveling. Especially in the condition of wet and sticky soil, this problem is more prominent, and soil adhesion has become an important technical bottleneck affecting the efficiency and effect of the roller in land restoration.

The roller is rotatably installed between the two frame bodies. The leveling shovel is fixedly connected to the two frame bodies. The scraper assembly is fixedly connected to the two frame bodies. The scraper assembly is in contact with the roller. The rolling brush is rotatably installed between the two frame bodies.

[0010] Preferably, the driving assembly comprises a motor, a first bevel gear and a second bevel gear; the motor is fixedly installed on the upper surface of the mounting plate, the first bevel gear is connected with the output end of the motor, the second bevel gear is fixedly connected with the transmission shaft, and the first bevel gear is meshingly connected with the second bevel gear.

[0012] Preferably, the vibration assembly comprises a rotating shaft and an eccentric wheel, the rotating shaft is rotatably installed between the two frame bodies, the second pulley is fixedly connected with the rotating shaft, and the rotating shaft passes through the eccentric wheel and is fixedly connected with the eccentric wheel.

[0013] Preferably, the scraper assembly comprises a scraper body and a guide plate, the scraper body and the guide plate are fixedly connected, the scraper body and the guide plate are installed between the two frame bodies, one side of the scraper body close to the compression roller is inclined downward and in contact with the compression roller, and one side of the guide plate close to the compression roller is inclined upward and in contact with the compression roller.

[0014] Preferably, the scraping shovel comprises a shovel body and a connecting seat, the shovel body is fixedly connected with the connecting seat, and the connecting seat is fixedly connected with the frame body.

[0015] One or more technical solutions provided in the application have at least the following technical effects or advantages:

[0016] The land repairing and leveling device provided by the utility model is driven by the traction equipment to move along the land surface. During the movement, the scraping shovel first contacts the land to preliminarily scrape and level the soil and remove the protruding or uneven part on the surface. Then, the compression roller rotates when the device advances, and the compression roller compacts the scraped land by using its own weight and rolling effect, so that the compactness and flatness of the soil are improved.

[0017] In the process of rolling compaction of the land, due to the adhesion of the soil, part of the soil will adhere to the outer surface of the roller. To solve this problem, the device is provided with a double cleaning mechanism of the scraper assembly and the rolling brush. Specifically, when the roller surface adhered with soil rotates to the position in contact with the scraper assembly, the scraper assembly scrapes most of the soil on the roller surface through the close contact with the roller surface. However, due to the size and viscosity difference of the soil particles, the scraper assembly may not completely remove all the fine soil residues. Therefore, the rolling brush further works behind the roller. During rotation, the bristles of the rolling brush contact the roller surface and form relative motion due to the opposite rotation direction of the roller, thereby effectively brushing off the fine soil particles remaining on the roller surface.

[0018] Through the above structure and operation mode, the device can significantly reduce the soil adhesion on the surface of the roller in the land repair and leveling operation. Through the cooperation of the scraper assembly and the rolling brush, there may still be a small amount of soil residues on the surface of the roller, but the residual amount is extremely small and will not have a substantial impact on the normal rotation of the roller or the effect of the land leveling operation. The design of the utility model improves the cleaning efficiency of the roller, prolongs the continuous operation time of the device, and thus improves the overall work efficiency of the land repair.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0031] As Figures 1 to 6 shown, the land repairing and leveling device aims to solve the problem of reduced work efficiency caused by the adhesion of mud on the surface of the compression roller in the prior art. The device comprises two frame bodies 1, a scraper 2, a compression roller 3, a scraper assembly 4, and a rolling brush 5. The structure of each component and its connection relationship are described as follows.

[0032] The pressing roller 3 is rotatably mounted between the two frame bodies 1, specifically, the two ends of the pressing roller 3 are connected to the two frame bodies 1 through bearings or other rotating connecting members, to ensure that the pressing roller 3 can freely rotate between the frame bodies 1. The scraping shovel 2 is fixedly connected to the two frame bodies 1, for example, through welding or bolt fixing, so that the scraping shovel 2 remains stable during operation of the device. The scraper assembly 4 is also fixedly connected to the two frame bodies 1, and is installed close to the pressing roller 3, and the working surface of the scraper assembly 4 is in direct contact with the outer surface of the pressing roller 3, for removing the attachments on the surface of the pressing roller 3. The rolling brush 5 is rotatably mounted between the two frame bodies 1, and the two ends thereof are also connected to the frame bodies 1 through bearings or other rotating connecting members. The bristles of the rolling brush 5 are in contact with the outer surface of the pressing roller 3, and the rotating direction of the rolling brush 5 is opposite to that of the pressing roller 3, to achieve further cleaning of the surface of the pressing roller 3.

[0033] The method for using the land repair and leveling device is as follows: first, the scraping shovel 2 is connected to an existing traction equipment (such as a tractor), and the connection mode can adopt a traction hook or other conventional mechanical connection structure. The traction equipment drives the entire device to move along the surface of the land. During the movement, the scraping shovel 2 first contacts the land to preliminarily scrape and level the soil and remove the protruding or uneven parts on the surface. Subsequently, the pressing roller 3 rotates during the advancement of the device, and compacts the scraped land by using its own weight and rolling action, thereby improving the compactness and flatness of the soil.

[0034] During the process of compacting the land by rotating the pressing roller 3, part of the soil will be attached to the outer surface of the pressing roller 3 due to the adhesion of the soil. To solve this problem, the device is provided with a double cleaning mechanism of the scraper assembly 4 and the rolling brush 5. Specifically, when the surface of the pressing roller 3 with soil attached rotates to the position in contact with the scraper assembly 4, the scraper assembly 4 scrapes most of the soil on the surface of the pressing roller 3 through the close contact with the surface of the pressing roller 3. However, due to the size and viscosity differences of the soil particles, the scraper assembly 4 may not be able to completely remove all the fine soil residues. Therefore, the rolling brush 5 further works behind the pressing roller 3. During the rotation of the rolling brush 5, the bristles thereof are in contact with the surface of the pressing roller 3, and due to the opposite rotating direction, the relative motion is formed, thereby effectively brushing away the fine soil particles remaining on the surface of the pressing roller 3.

[0035] Through the above structure and operation mode, the device can significantly reduce the soil attachment on the surface of the pressing roller 3 in the land repair and leveling operation. Through the cooperation of the scraper assembly 4 and the rolling brush 5, there may still be a small amount of soil residues on the surface of the pressing roller 3, but the residual amount is extremely small and will not have a substantial impact on the normal rotation of the pressing roller 3 or the effect of the land leveling operation. The design of the device improves the cleaning efficiency of the pressing roller 3, prolongs the continuous operation time of the device, and thereby improves the overall work efficiency of the land repair.

[0036] In the embodiment, a vibration assembly 6 is also rotatably installed between the two frame bodies 1. The interior of the compression roller 3 is designed as a hollow structure to accommodate the vibration assembly 6. Specifically, the vibration assembly 6 is arranged in the interior of the compression roller 3 and connected to the two frame bodies 1 through a rotary connection (such as a bearing or a shaft sleeve), ensuring that the vibration assembly 6 can stably operate inside the compression roller 3. The vibration assembly 6 can be an existing vibration generating device, such as an eccentric vibrator or a motor-driven oscillation mechanism, and its specific structure is not limited here, but its function is to generate stable vibration.

[0037] In use, the vibration assembly 6 generates vibration when it works, which is first transmitted to the two frame bodies 1 through the connection between the vibration assembly 6 and the frame bodies 1. Since the frame bodies 1 are fixedly connected to the compression roller 3 or indirectly connected through a rotary structure, the vibration is further transmitted from the frame bodies 1 to the housing of the compression roller 3. The compression roller 3 produces a slight oscillation while rolling and compacting the soil under the action of the vibration transmitted by the vibration assembly 6. This vibration can enhance the compaction effect of the compression roller 3 on the soil, especially in loose or high-moisture soil, vibration helps to rearrange soil particles, further improving the density and stability of the soil.

[0038] In addition, the arrangement of the vibration assembly 6 can also help to reduce the adhesion of soil on the surface of the compression roller 3. Since the surface of the compression roller 3 is in a dynamic state under the action of vibration, the soil adhering to it is more easily loosened under the action of vibration, thereby facilitating the subsequent cleaning by the scraper assembly 4 and the roller brush 5. Through the cooperation of the vibration assembly 6 and the compression roller 3, the device not only improves the efficiency of land leveling and compaction, but also further optimizes the cleaning performance of the compression roller 3, ensuring the stability of long-time operation.

[0039] In the embodiment, the land repair and leveling device also includes a driving assembly 7 and a transmission assembly 8. To facilitate the installation and support of the above-mentioned assemblies, the upper side of the two frame bodies 1 is fixedly provided with a mounting plate 11. The driving assembly 7 is installed on the upper surface of the mounting plate 11 and connected to the vibration assembly 6 and the roller brush 5 through the transmission assembly 8 to realize power transmission. The driving assembly 7 can be a motor, a hydraulic motor or other conventional power source, and its specific form is not limited here, and its function is to provide rotary driving force.

[0040] The specific structure of the transmission assembly 8 includes a transmission shaft 81, two first gears 82, two second gears 83, two first pulleys 84, two second pulleys 85, and a transmission belt 86. The transmission shaft 81 is rotatably connected to the mounting plate 11 through a bearing or other rotary connecting member, and one end of the transmission shaft 81 is connected to the output end of the driving assembly 7, so that the driving assembly 7 can drive the transmission shaft 81 to rotate around its axis. Two first gears 82 are sleeved on the transmission shaft 81 and are fixedly connected to the transmission shaft 81 through key connection or welding, etc., to rotate synchronously with the transmission shaft 81. Two second gears 83 are fixedly connected to the two ends of the roller brush 5, for example, through a shaft sleeve or a key groove structure, and each first gear 82 is meshingly connected to the corresponding second gear 83 to transmit rotary power.

[0041] Meanwhile, two first pulleys 84 are also sleeved on the transmission shaft 81 and are fixedly connected to the transmission shaft 81 to rotate synchronously with the transmission shaft 81. Two second pulleys 85 are respectively connected to the rotary input end of the vibration assembly 6, for example, through shaft connection or other fixing means to realize power transmission. The transmission belt 86 is wound between the corresponding first pulley 84 and the second pulley 85 to form a belt transmission structure, so as to transmit the rotation of the first pulley 84 to the second pulley 85. The transmission belt 86 can be a belt, a chain or other flexible transmission member, and its specific form is selected according to actual needs.

[0042] The working process of the device is as follows: when the driving assembly 7 starts, its output power drives the transmission shaft 81 to rotate. The rotation of the transmission shaft 81 simultaneously drives the first gear 82 and the first pulley 84 fixed thereon to rotate in a first direction (for example, clockwise). The first pulley 84 transmits the rotation to the second pulley 85 through the transmission belt 86, so that the second pulley 85 also rotates in the first direction, thereby driving the vibration assembly 6 to rotate in the first direction, generating vibration and transmitting it to the compression roller 3 through the aforementioned mode. At the same time, the device advances under the traction of the traction equipment, and the compression roller 3 rolls due to contact with the ground, and the rolling direction is the first direction.

[0043] Under the drive of the transmission shaft 81, the first gear 82 meshes with the second gear 83, so that the second gear 83 rotates in a second direction (for example, counterclockwise, opposite to the first direction). The roller brush 5 fixed to the second gear 83 rotates in the second direction. Since the rotation direction of the roller brush 5 is opposite to the rolling direction of the compression roller 3, the bristles of the roller brush 5 can generate relative motion when contacting the surface of the compression roller 3, thereby effectively brushing off the fine soil particles remaining on the surface of the compression roller 3, further improving the cleaning effect.

[0044] Through the cooperation of the driving assembly 7 and the transmission assembly 8, the device realizes the unified driving of the vibration assembly 6 and the rolling brush 5, ensures the simultaneous operation of the vibration compaction and the surface cleaning function. The design of the reverse rotation of the rolling brush 5 and the compression roller 3 not only improves the thoroughness of soil cleaning, but also reduces the influence of the soil attached to the surface of the compression roller 3 on the leveling operation, thereby ensuring the efficiency and stability of the device in the land restoration process.

[0045] In the embodiment, the driving assembly 7 includes a motor 71, a first bevel gear 72 and a second bevel gear 73. The motor 71 is firmly installed on the upper surface of the mounting plate 11 through bolts or other fixing methods to ensure the stability during operation. The first bevel gear 72 is connected with the output end of the motor 71, for example, through key connection or shaft coupling to realize fixation, to receive the rotating power of the motor 71. The second bevel gear 73 is sleeved on the transmission shaft 81 and is fixedly connected with the transmission shaft 81 through key connection or welding. The first bevel gear 72 and the second bevel gear 73 are meshed with each other to form a bevel gear transmission structure for changing the direction of power transmission and driving the transmission shaft 81.

[0046] The driving process is as follows: after starting the motor 71, the output end of the motor 71 drives the first bevel gear 72 to rotate. The first bevel gear 72 transmits the rotating power to the second bevel gear 73 through the meshing with the second bevel gear 73, so that the second bevel gear 73 rotates. Since the second bevel gear 73 is fixedly connected with the transmission shaft 81, the transmission shaft 81 rotates around its axis under the driving of the second bevel gear 73, thereby realizing the effective driving of the transmission shaft 81 and providing power for the subsequent vibration assembly 6 and rolling brush 5.

[0047] In the embodiment, the upper surface of the mounting plate 11 is also provided with a storage battery 9. The storage battery 9 is electrically connected with the motor 71 through wires to provide stable power supply for the motor 71. The storage battery 9 can be a rechargeable battery, and its capacity and specifications are configured according to the power demand of the motor 71 to ensure the continuous operation ability of the device in the environment without external power supply.

[0048] In the embodiment, the vibration assembly 6 includes a rotating shaft 61 and an eccentric wheel 62. The rotating shaft 61 is rotatably installed between the two frame bodies 1 through bearings or other rotating connecting members, and the two ends thereof are connected with the frame bodies 1 respectively to maintain stability. The second pulley 85 is fixedly connected with one end of the rotating shaft 61, for example, through key slots or fasteners to realize synchronous rotation. The rotating shaft 61 penetrates through the eccentric wheel 62 and is fixedly connected with the eccentric wheel 62 through welding or key connection, so that the rotating shaft 61 can drive the eccentric wheel 62 to rotate synchronously when the rotating shaft 61 rotates.

[0049] The working principle of the vibration assembly 6 is as follows: when the transmission assembly 8 drives the rotating shaft 61 to rotate through the second belt pulley 85, the rotating shaft 61 drives the eccentric wheel 62 to rotate around the axis of the rotating shaft 61. Since the center of gravity of the eccentric wheel 62 is offset from the rotation center of the rotating shaft 61, the rotation of the eccentric wheel 62 will generate a periodic centrifugal force, so that the rotating shaft 61 vibrates. The vibration of the rotating shaft 61 is transmitted to the two frame bodies 1 through the connecting part of the rotating shaft 61 and the frame bodies 1, and further transmitted to the compression roller 3 through the frame bodies 1. The compression roller 3 generates slight oscillation under the vibration effect while rolling and compacting the soil, which can enhance the compacting effect of soil particles, and is especially suitable for compacting loose or wet and sticky soil.

[0050] In the embodiment, the scraper assembly 4 comprises a scraper body 41 and a guide plate 42, which are fixedly connected by welding or bolt fixing or the like. The scraper body 41 and the guide plate 42 are jointly installed between the two frame bodies 1, and their two ends are fixed with the frame bodies 1 to maintain the structural stability. The side of the scraper body 41 close to the compression roller 3 is designed as a downwardly inclined structure, and is in contact with the outer surface of the compression roller 3 to scrape the attached soil on the surface of the compression roller 3. The side of the guide plate 42 close to the compression roller 3 is upwardly inclined, and is also in contact with the outer surface of the compression roller 3 to guide the cleaned soil.

[0051] The working process of the scraper assembly 4 is as follows: during the travel of the device, the soil attached to the surface of the compression roller 3 is moved to the position in contact with the scraper body 41 by the rotation of the compression roller 3. The scraper body 41 scrapes the soil from the surface of the compression roller 3 through the inclined working surface thereof. Then, the slight residual soil on the surface of the compression roller 3 is further cleaned by the rolling brush 5 as the compression roller 3 continues to rotate, and the cleaned soil falls on the guide plate 42. Since the guide plate 42 is upwardly inclined, the scraped soil moves away from the compression roller 3 along the inclined direction of the guide plate 42, avoiding the cleaned soil from falling back to the surface of the compression roller 3 or accumulating in the device. This double structural design improves the efficiency of soil cleaning, reduces the possibility of secondary pollution, ensures the cleaning state of the compression roller 3 in long-term operation, and maintains the quality of land leveling and the running stability of the device.

[0052] In the embodiment, the scraping shovel 2 comprises a shovel body 21 and a connecting seat 22. The shovel body 21 and the connecting seat 22 are firmly connected by welding, bolting or other conventional fixing methods to ensure the stability between them during operation. The two ends of the connecting seat 22 are fixedly connected with two frame bodies 1, for example, by bolts or pins fixed to the preset mounting positions of the frame bodies 1, so as to fix the scraping shovel 2 as a whole on the frame structure of the device. The connecting seat 22 is provided with structures for connecting the traction equipment, such as traction holes or hooks, which can be adapted according to the connection requirements of the traction equipment (such as a tractor) used, for connecting the device with the traction equipment and moving the whole device. The shovel body 21 is the working part of the scraping shovel 2, and its lower edge is designed as a flat or slightly arc-shaped structure suitable for contacting the land surface for scraping the soil.

[0053] During use, when the traction equipment drives the device along the land surface through the connecting seat 22, the shovel body 21 first contacts the soil. The shovel body 21 scrapes the land through its lower edge to push the protruding, uneven or loose soil on the surface flat, providing a flat base surface for the subsequent compaction operation of the compactor roller 3. The width of the shovel body 21 is usually matched with the width of the compactor roller 3 to ensure that the scraping range is consistent with the compaction range, thereby improving the overall effect of land repair. In addition, the shovel body 21 can be made of wear-resistant materials (such as steel plates) or provided with wear-resistant coatings on its working edge according to actual needs to prolong the service life and adapt to the operation requirements of different soil conditions.

[0054] The above specific embodiments do not constitute a limitation on the protection scope of the present application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
