Description

Technical Field

[0001] This utility model relates to the technical field of construction equipment, and in particular to a soil leveling device. Background Technology

[0002] The foundation refers to the soil or rock mass beneath a building that serves as its supporting base. The soil layers used for building foundations are mainly classified as rock, gravelly soil, sandy soil, silty soil, clayey soil, and artificial fill. Foundation treatment typically requires the use of soil compaction equipment for leveling and compaction.

[0003] Chinese utility model patent CN222715755U discloses a road leveling machine for asphalt concrete pavement laying, including a pressure roller and a first cleaning component for cleaning the pressure roller. The first cleaning component includes a mounting plate, a water tank, and a scraper. The mounting plate is mounted above the pressure roller and has multiple spray nozzles. The water tank is connected to each spray nozzle via a water pump and connecting pipes for supplying water to the spray nozzles. The scraper is mounted on the mounting plate and has a scraping end face with a triangular cross-section. The scraping end face contacts the outer surface of the pressure roller and is used to scrape off debris adhering to the outer surface of the pressure roller. This patent achieves surface scraping and rinsing of the pressure roller during the ground leveling process, effectively ensuring that debris adhering to the surface of the pressure roller can be removed in a timely manner, avoiding problems caused by debris preventing leveling during subsequent leveling processes.

[0004] However, the scraper in this patent remains in constant contact with the pressure roller. This continuous friction causes the scraper to gradually wear down, creating a gap between it and the pressure roller. Consequently, it cannot effectively remove debris, affecting the cleaning effect. Ultimately, the residue remaining on the pressure roller will make it difficult to ensure the leveling quality of the floor. Utility Model Content

[0005] To address the technical problem that the existing device suffers from increased gap between the scraper and the pressure roller due to continuous wear, which in turn affects the cleaning effect, this utility model provides a soil leveling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: Soil leveling equipment includes a frame, a pressure roller, and a cleaning assembly for cleaning the pressure roller. The pressure roller is located below the frame, and the cleaning assembly is mounted on the frame. The cleaning assembly includes: The first transmission component is slidably mounted on the frame and can move in the vertical direction; The trigger block is rotatably connected to the frame. The rotation axis of the trigger block is parallel to the rotation axis of the pressure roller. The rotation axis of the pressure roller extends in the left and right direction. The front side of the trigger block contacts the outer circumferential surface of the pressure roller. The rear side of the trigger block is provided with a support surface, which contacts the lower end of the first transmission component. When the trigger block rotates toward the side of the first transmission component, it can push the first transmission component to move upward. The scraper is slidably mounted on the frame and can switch between a first state and a second state. In the first state, the bottom end of the scraper is away from the outer peripheral surface of the pressure roller. In the second state, the bottom end of the scraper is in contact with the outer peripheral surface of the adjacent trigger block on the pressure roller. The transmission mechanism is disposed between the scraper and the first transmission member, and acts on the scraper and the first transmission member respectively, converting the upward movement of the first transmission member into the downward movement of the scraper, and converting the downward movement of the first transmission member into the upward movement of the scraper. A reset component is disposed at any point in the entire kinematic chain from the first transmission component to the scraper, and is used to reset the scraper and the first transmission component.

[0007] Furthermore, the lower end face of the scraper is wedge-shaped, with its tip facing the outer circumferential surface of the pressure roller, and is used to scrape off the adhering substances on the surface of the pressure roller.

[0008] Furthermore, the length direction of the trigger block is parallel to the central axis of the pressure roller, and the cross-sectional shape of the trigger block perpendicular to its own length direction is fan-shaped.

[0009] Furthermore, the transmission mechanism includes a first transmission shaft and a second transmission shaft that are parallel to each other. Both the first and second transmission shafts extend in the left-right direction and are synchronously connected. A support is provided on the frame, and both the first and second transmission shafts are rotatably connected to the support. A first gear is coaxially fixed on the first transmission shaft, and a first rack portion that meshes with the first gear is provided on the first transmission component. Rotation of the first gear can drive the first transmission component to move up and down. A second gear is coaxially fixed on the second transmission shaft, and a second rack portion that meshes with the second gear is provided on the scraper. Rotation of the second gear can drive the scraper to contact or move away from the outer circumferential surface of the pressure roller near the trigger block.

[0010] Furthermore, both the first and second drive shafts are equipped with pulleys, and belts are wound around the pulleys to realize the transmission between the first and second drive shafts.

[0011] Furthermore, there are two first transmission components, which are arranged side by side at intervals in the left-right direction, and the number of first gears is correspondingly set to two.

[0012] Furthermore, the lower end face of the first transmission component is set as an inclined surface, and in the initial state, the inclined surface is parallel to the support surface and remains in contact.

[0013] Furthermore, the scraper is angled downwards from front to back.

[0014] Furthermore, the reset component is a spring, which is mounted on the scraper. A fixed seat is provided on the frame, with one end of the spring connected to the fixed seat and the other end connected to the scraper.

[0015] Furthermore, the trigger block has a shaft hole along its own length, and a rotating shaft is provided on the frame. The rotating shaft extends in the left and right direction and passes through the shaft hole, allowing the trigger block to rotate around the axis of the rotating shaft.

[0016] The beneficial effects of this utility model are: This invention solves the problem of continuous wear and reduced cleaning efficiency caused by the scraper's constant contact with the pressure roller in traditional technologies by setting up a first transmission component, a trigger block, a scraper, a transmission mechanism, and a reset component. Through a mechanical linkage structure, it addresses this issue. A trigger block, in contact with the pressure roller surface, acts as a sensing mechanism. When more debris adheres to the pressure roller, the trigger block rotates, pushing the first transmission component upwards. This movement is immediately converted into a downward pressing action of the scraper via the transmission mechanism, ensuring that it only contacts the pressure roller for scraping when actually needed. This purely mechanical feedback mechanism of "sensing-triggering-action" reduces idle wear.

[0017] Furthermore, the cleaning force of this component can be adaptively adjusted. The more debris there is, the greater the rotation amplitude of the trigger block, ultimately causing the scraper to press against the outer circumference of the pressure roller with greater pressure, ensuring effective removal of thick, adhered materials. After cleaning, all components automatically reset under the action of the reset mechanism, and the scraper lifts away from the outer circumference of the pressure roller, achieving zero-contact standby. The entire system requires no electronic sensors or controllers, relying solely on the linkage of mechanical components. Its robust and durable structure is well-suited to the harsh working conditions of high vibration and dust on construction sites, significantly extending the scraper's service life and ensuring stable leveling quality.

[0022] Reference Figures 1 to 2 This utility model provides a soil leveling device.

[0023] like Figures 1 to 2 As shown, in some embodiments, a soil leveling device is provided, including a frame 1, a pressure roller 2, and a cleaning assembly for cleaning the pressure roller 2. The pressure roller 2 is located below the frame 1, and the cleaning assembly is mounted on the frame 1. The cleaning assembly includes: The first transmission component 3 is slidably mounted on the frame 1 and can move in the up and down direction; The trigger block 4 is rotatably connected to the frame 1. The rotation axis of the trigger block 4 is parallel to the rotation axis of the pressure roller 2. The rotation axis of the pressure roller 2 extends in the left and right direction. The front side of the trigger block 4 contacts the outer peripheral surface of the pressure roller 2. The rear side of the trigger block 4 is provided with a support surface 5. The support surface 5 contacts the lower end of the first transmission member 3. When the trigger block 4 rotates toward the side of the first transmission member 3, it can push the first transmission member 3 to move upward. The scraper 6 is slidably mounted on the frame 1 and can switch between a first state and a second state. In the first state, the bottom end of the scraper 6 is away from the outer peripheral surface of the pressure roller 2. In the second state, the bottom end of the scraper 6 is in contact with the outer peripheral surface of the adjacent trigger block 4 on the pressure roller 2. The transmission mechanism is located between the scraper 6 and the first transmission member 3, and acts on the scraper 6 and the first transmission member 3 respectively, converting the upward movement of the first transmission member 3 into the downward movement of the scraper 6, and converting the downward movement of the first transmission member 3 into the upward movement of the scraper 6. A reset component is provided at any point in the entire motion chain from the first transmission component 3 to the scraper 6, and is used to reset the scraper 6 and the first transmission component 3.

[0024] The first transmission component 3 can be a strip plate, a square plate, or other shaped component; its shape is not particularly limited. It can be slidably mounted on the frame 1 and can slide up and down. For the first transmission component 3 to be slidably mounted on the frame 1, a groove can be provided on the frame 1, and the first transmission component 3 can be inserted into the groove and slide in contact; alternatively, a slide rail can be provided on the frame 1, and a slider on the first transmission component 3 can slide in cooperation with the slide rail; another option is to provide a groove on the first transmission component 3 and a slider on the frame 1 to achieve a sliding fit. Besides these, existing sliding fit structures can also be used. For the scraper 6 to be slidably mounted on the frame 1, the sliding fit between the first transmission component 3 and the frame 1 can be referenced.

[0025] like Figures 1 to 2 As shown, for the trigger block 4 to be rotatably connected to the frame 1, optionally, the trigger block 4 has a shaft hole 17 along its own length direction, and the frame 1 is provided with a rotating shaft that extends in the left-right direction and passes through the shaft hole 17, allowing the trigger block 4 to rotate around the axis of the rotating shaft; alternatively, spherical grooves can be provided on both the left and right sides of the trigger block 4, and spherical protrusions can be provided on the frame 1, with the spherical protrusions spherically hinged to the spherical grooves to achieve a rotatable connection; alternatively, bearings can be installed on the left and right sides of the trigger block 4, and a rotating shaft can be provided on the frame 1, with the rotating shaft passing through the bearings. In addition, existing achievable rotatable connection methods can also be used.

[0026] like Figures 1 to 2 As shown, for the transmission mechanism, optionally, a first rack portion 11 is provided on the first transmission member 3, and a second rack portion 13 is provided on the scraper 6. A mating gear is provided between the two. The first rack portion 11 meshes with the rear side of the mating gear, and the second rack portion 13 meshes with the front side of the mating gear. When the first rack portion 11 moves upward, it drives the mating gear to rotate counterclockwise, thereby driving the second rack portion 13 to move downward. In order to make the movement smoother and increase the distance between the scraper 6 and the first transmission member 3, so as to facilitate the tilt adjustment of the scraper 6, provide ample installation space for the scraper 6 and the first transmission member 3, and improve the installation flexibility, the transmission mechanism can also be configured as follows: the transmission mechanism includes mutually parallel first transmission shafts. 7 and 8 are both extended in the left and right direction. The first drive shaft 7 and the second drive shaft 8 are synchronously connected. The frame 1 is provided with a support 9. The first drive shaft 7 and the second drive shaft 8 are rotatably connected to the support 9. The first gear 10 is coaxially fixed on the first drive shaft 7. The first transmission member 3 is provided with a first rack part 11 that meshes with the first gear 10. The rotation of the first gear 10 can drive the first transmission member 3 to move up and down. The second gear 12 is coaxially fixed on the second drive shaft 8. The scraper 6 is provided with a second rack part 13 that meshes with the second gear 12. The rotation of the second gear 12 can drive the scraper 6 to contact or move away from the outer peripheral surface of the pressure roller 2 near the trigger block 4.

[0027] like Figures 1 to 2 As shown, the first drive shaft 7 and the second drive shaft 8 are synchronously connected. Optionally, both the first drive shaft 7 and the second drive shaft 8 are provided with pulleys 14, and belts 15 are wound around the pulleys 14 to realize the transmission between the first drive shaft 7 and the second drive shaft 8. Sprockets and chains can also be used for synchronous transmission. For the belt 15, a synchronous belt is preferred, and the pulleys 14 are also selected with gears that are compatible with the synchronous belt.

[0028] The reset element can be located at any point in the entire kinematic chain from the first transmission member 3 to the scraper 6. For example, the reset element can be a spring 16, mounted on the scraper 6 or the first transmission member 3; alternatively, the reset element can be a torsion spring mounted on the first transmission shaft 7 or the second transmission shaft 8. These are not all listed here. Theoretically, by placing a suitable reset element at any point in the entire kinematic chain from the first transmission member 3 to the scraper 6, the reset of one component can drive the reset of other components.

[0029] like Figures 1 to 2 As shown, generally speaking, the lower end face of the scraper 6 is wedge-shaped, with its tip facing the outer circumference of the pressure roller 2, used to scrape off the adhering substances on the surface of the pressure roller 2. Of course, a regular plate-shaped scraper 6 can also scrape off the adhering substances on the surface of the pressure roller 2, but the effect is slightly less. The contact area between the wedge-shaped tip and the pressure roller 2 is very small. When the scraper 6 is subjected to the same downward pressure, the smaller the contact area, the greater the pressure generated. The huge pressure allows the cutting edge of the scraper 6 to easily cut into and pry off the dirt, asphalt, or other debris tightly adhering to the surface of the pressure roller 2, thereby achieving efficient scraping. In contrast, a flat scraper 6 has a large contact area and low pressure, which is more like "rubbing" or "pushing" the debris, easily causing the debris to be flattened rather than removed, greatly reducing the effect.

[0030] In the first state, the bottom of the scraper 6 does not contact the pressure roller 2, thus avoiding long-term wear. Of course, to improve the accuracy of the movement, the bottom of the scraper 6 can be as close as possible to the outer peripheral surface of the adjacent trigger block 4 on the pressure roller 2. When the front side of the trigger block 4 contacts the pressure roller 2 and there is no adhesive on the pressure roller 2, the pressure roller 2 will not drive the trigger block 4 to rotate. This is because in the initial state, the trigger block 4 is vertically hanging down, and the pressure roller 2 will not exert a backward force on the trigger block 4, but only a vertically upward frictional force. Therefore, the trigger block 4 will not rotate around the rotation axis.

[0031] like Figures 1 to 2As shown, the preferred shape of the trigger block 4 is that its length direction is parallel to the central axis of the pressure roller 2, and its cross-sectional shape perpendicular to its length direction is fan-shaped. Alternatively, conventional strip-shaped blocks or other shapes can also achieve the triggering function, provided that the length of the trigger block 4 is greater than or equal to the length of the pressure roller 2, and the trigger block 4 has a contact portion that contacts the outer circumferential surface of the pressure roller 2. Depending on the actual use, only a portion of the pressure roller 2 can be cleaned, or the entire outer circumferential surface of the pressure roller 2 can be cleaned. During overall cleaning, the contact portion of the trigger block 4 continuously contacts the outer circumference of the pressure roller 2 and covers the length of the pressure roller 2, so that any adhering material on any part of the pressure roller 2 will trigger the trigger block 4 to react. If the entire outer circumferential surface of the pressure roller 2 needs to be cleaned, the length of the scraper 6 should also be greater than or equal to the length of the pressure roller 2. When the trigger block 4 rotates towards the side of the first transmission member 3, the trigger support surface 5 can provide an upward thrust to push the first transmission member 3 upward.

[0032] To increase transmission smoothness, there are two first transmission components 3, arranged side-by-side at intervals in the left-right direction, and two first gears 10 are correspondingly arranged. Of course, the width of the first transmission component 3 can also be designed to be larger, for example, by combining two or three first transmission components 3 together, which can also increase transmission smoothness and reduce shaking.

[0033] like Figures 1 to 2 As shown, regarding the contact between the first transmission component 3 and the support surface 5, preferably, the lower end surface of the first transmission component 3 is set as an inclined surface. In the initial state, the inclined surface is parallel to and in contact with the support surface 5. With this design, the first transmission component 3 and the trigger block 4 have a larger contact area, and the surface contact can withstand greater pressure, avoiding damage to the components. Of course, if the first transmission component 3 and the support surface 5 are made of a higher strength material, they can also make point contact or line contact.

[0034] like Figures 1 to 2 As shown, to make the cleaning response more immediate and efficient, the scraper 6 is specifically designed in terms of spatial layout: the scraper 6 is tilted downwards from front to back, and the lower tilted end of the scraper 6 is as close as possible to the trigger block 4, so that its wedge-shaped cutting edge is as close as possible to the surface of the pressure roller 2 near the trigger block 4 in the initial (standby) position. The core purpose of this layout is to maximize the immediacy of the cleaning response and utilize the movement of the pressure roller 2 itself. The cutting edge of the scraper 6 is like a "scalpel" pre-positioned near the "incident site," ready to immediately perform scraping operations upon receiving a signal.

[0035] Induction triggering stage: During the rolling and pressing process, impurities gradually adhere to the surface of the pressure roller 2, causing a local increase in roller diameter. When this thickened area rotates with the pressure roller 2 and comes into contact with the trigger block 4, it will lift the front side of the trigger block 4. The trigger block 4 rotates around its rotation axis, and the rear side of the trigger block 4 rotates backward and upward at an angle. The supporting surface 5 on its rear side rises accordingly, pushing the first transmission component 3 in contact with it to move upward.

[0036] Power transmission and the downward movement of scraper 6: The upward linear motion of the first transmission component 3 is converted into the downward linear motion of scraper 6 through the transmission mechanism. Since the initial position of scraper 6 is already inclined and very close to pressure roller 2, it only needs a very short downward stroke for its cutting edge to quickly press against the surface of pressure roller 2.

[0037] Scraping Operation Stage: At this stage, two key points occur simultaneously. First, the scraper 6 is pressed down into position, with its cutting edge contacting the surface of the pressure roller 2 with a certain pressure. Second, the pressure roller 2 continues to roll, and the surface of the pressure roller 2 with adhering debris is moving forward from the trigger block 4 position (towards the scraper 6 position). The wedge-shaped cutting edge of the scraper 6 precisely scrapes into the adhering material, and as the pressure roller 2 rotates, the adhering material is continuously scraped up and peeled off by the sturdy cutting edge of the scraper 6. This design is more suitable for scraping large areas of adhering material. For small amounts of adhering material, the scraping precision is slightly lower, but it can still complete the scraping of the vast majority of adhering material.

[0038] like Figures 1 to 2 As shown, the reset component is a spring 16, which is mounted on the scraper 6. A fixed seat is provided on the frame 1. One end of the spring 16 is connected to the fixed seat, and the other end is connected to the scraper 6. The spring 16 can be either a tension spring or a compression spring. The specific method depends on the installation location. For example, if it is installed on the upper surface of the frame 1 and on the scraper 6, the spring 16 is compressed when the scraper 6 moves downwards, so a compression spring is used for reset. If it is installed on the lower surface of the frame 1 and on the scraper 6, the spring 16 is stretched when the scraper 6 moves downwards, so a tension spring is used for reset. Alternatively, components with elastic functions, such as rubber strips or other components with elastic reset functions, can be used.
