A mud scraper and a road roller

Abstract

This application provides a sludge scraping device and a road roller, relating to the field of sludge scraping technology. The sludge scraping device includes: a mounting base for connection to a road roller; a first mounting member hinged to the mounting base; a sludge scraper connected to the first mounting member; and an elastic member, one end of which is connected to the first mounting member, and the other end of which is connected to the mounting base. The first mounting member is rotatable relative to the mounting base, allowing the sludge scraper to switch between a sludge scraping position and an open position. This application allows the elastic member to pull the first mounting member upwards or downwards within the rotation range of the elastic member, thereby keeping the sludge scraper in an open state when raised and in a sludge scraping state when pressed down, increasing the distance between the scraper blade and the roller surface, facilitating operation (e.g., allowing larger foreign objects to pass through and preventing them from jamming the scraper blade).

Description

Technical Field

[0001] This application relates to the field of mud scraping technology, and more particularly to a mud scraping device and a road roller. Background Technology

[0002] During operation, foreign objects, such as mud, may adhere to the rollers, affecting their normal function. Therefore, a mud scraper should be installed on the rollers to remove the mud from their surface.

[0003] In the prior art, the sludge scraping device includes a sludge scraper mounting plate, a sludge scraper, a tension spring, and an adjusting screw. The sludge scraper mounting plate is connected to the road roller via a hinge shaft. The sludge scraper mounting plate is connected to the sludge scraper. The tension spring is located below the hinge shaft and connects to the sludge scraper, bringing the sludge scraper close to the roller surface. The adjusting screw adjusts the rotation position of the sludge scraper mounting plate, thereby adjusting the distance between the sludge scraper and the roller surface.

[0004] However, no matter how the limit screw is adjusted, that is, no matter how the scraper mounting plate rotates, the extension line of the spring tension is always located below the scraper, so that the scraper mounting plate is always subjected to force towards the side closer to the roller surface. The scraper mounting plate cannot be fully opened upwards, resulting in a narrower distance between the scraper and the roller surface. Utility Model Content

[0005] This application provides a sludge scraping device and a road roller to solve the problem in the prior art that no matter how the limit screw is adjusted, that is, no matter how the scraper mounting plate rotates, the extension line of the spring tension is always located below the scraper, so that the scraper mounting plate is always subjected to force towards the side close to the roller surface, and the scraper mounting plate cannot be fully opened upwards, resulting in a narrow distance between the scraper and the roller surface.

[0006] To achieve the above objectives, the technical solution of this application is as follows:

[0007] On one hand, this application provides a sludge scraping device, comprising: a mounting base for connection to a road roller; a first mounting member hinged to the mounting base; a sludge scraper connected to the first mounting member; and an elastic member, one end of which is connected to the first mounting member and the other end of which is connected to the mounting base; the first mounting member is rotatable relative to the mounting base to switch the sludge scraper between a sludge scraping position and an open position; in the sludge scraping position, the sludge scraper abuts against the surface of a wheel component, and the center of the elastic member is located below the hinge point between the first mounting member and the mounting base; in the open position, the center of the elastic member is located above the hinge point between the first mounting member and the mounting base, and keeps the sludge scraper away from the surface of the wheel component.

[0008] In one possible implementation, the sludge scraping device in this application embodiment includes a mounting base comprising a first body, a second body, and a hinge shaft rotatably disposed within the first body. The first mounting member is connected to the hinge shaft, and the end of the first mounting member facing the sludge scraper has a first connecting portion. The first connecting portion and the second body are respectively disposed on opposite sides of the hinge shaft and respectively connected to the two ends of the elastic member. The first mounting member rotates around the hinge shaft, causing the first connecting portion to rotate relative to the second body, so that the center of the elastic member is located below or above the hinge shaft.

[0009] In one possible implementation, the sludge scraping device in this application embodiment has a first body with a mounting through hole, a hinge shaft rotatably disposed in the mounting through hole, and two ends of the first mounting member passing through the mounting through hole from the hinge shaft to form two extensions located on opposite sides of the first body, the extensions facing the sludge scraping member having the first connecting portion.

[0010] In one possible implementation, the mud scraping device in this application embodiment further includes a fixing plate on the mounting base, the fixing plate being connected to the first body and located below the hinge shaft;

[0011] When in the open position, the fixing plate abuts against the first mounting member to restrict the rotational position of the first mounting member.

[0012] In one possible implementation, in the mud scraping device of this application embodiment, the fixed plate is inclined and the inclined direction is toward the extension section that is disposed away from the mud scraper. The extension section has a bent portion that is inclined toward the fixed plate. In the open position, the bent portion is used to abut against the fixed plate.

[0013] In one possible implementation, the mud scraping device in this application embodiment further includes an adjusting member, which is inserted into the first mounting member and abuts against the mounting seat at the mud scraping position. The adjusting member moves toward the mounting seat to adjust the relative position between the mud scraper and the surface of the wheel component.

[0014] In one possible implementation, the mud scraping device in this application embodiment has an adjusting screw or a limiting cam as the adjusting element.

[0015] In one possible implementation, the sludge scraping device in this application embodiment further includes a hook member located on one side of the first mounting member, and the hook member is used to abut against the first mounting member to limit the rotational position of the first mounting member.

[0016] In one possible implementation, the mud scraping device in this application embodiment includes at least two elastic elements, which are respectively disposed at opposite ends of the first mounting member.

[0017] This application also provides a road roller, including a body and a sludge scraper device disposed on the body as described in any of the above embodiments.

[0018] This application provides a sludge scraping device and a road roller. The road roller includes: a mounting base for connecting to the road roller; a first mounting member hinged to the mounting base; a sludge scraper connected to the first mounting member; and an elastic member, one end of which is connected to the first mounting member and the other end of which is connected to the mounting base. The first mounting member is rotatable relative to the mounting base to allow the sludge scraper to switch between a sludge scraping position and an open position. This application drives the first mounting member to rotate around the hinge point to the scraping position under the action of external force. At this time, the center of the elastic element is located below the hinge point, and the elastic element provides a downward pulling force to the scraper, keeping the lower edge of the scraper in contact with the surface of the wheel component, thus performing the scraping function. Alternatively, the first mounting member can be driven to rotate around the hinge point to the open position. At this time, the center of the elastic element is located above the hinge point, and the elastic element provides an upward pulling force to the scraper. The upward pulling force moves the scraper away from the surface of the wheel component and keeps the scraper in the open position, increasing the distance between the scraper blade and the roller surface, facilitating operation (such as allowing larger foreign objects to pass through and preventing them from jamming the scraper blade). Therefore, in this application, the hinge point between the first mounting member and the mounting base is within the rotation range of the elastic element, allowing the elastic element to pull the first mounting member upward or downward, thereby keeping the scraper in the open state when raised and in the scraping state when pressed down, increasing the distance between the scraper blade and the roller surface, thus facilitating operation.

[0035] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] It should be noted that in the description of the embodiments of this application, the terms "upper", "lower", "inner", "outer" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description, and are not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0038] Furthermore, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In the prior art, the sludge scraping device includes a sludge scraper mounting plate, a sludge scraper, a tension spring, and an adjusting screw. The sludge scraper mounting plate is connected to the road roller via a hinge shaft. The sludge scraper mounting plate is connected to the sludge scraper. The tension spring is located below the hinge shaft and connects to the sludge scraper, bringing the sludge scraper close to the roller surface. The adjusting screw adjusts the rotation position of the sludge scraper mounting plate, thereby adjusting the distance between the sludge scraper and the roller surface.

[0041] However, regardless of how the limit screw is adjusted, and no matter how the scraper mounting plate rotates, the extension line of the spring tension always lies below the scraper. This means the scraper mounting plate is always subjected to force towards the side closest to the roller surface, preventing it from opening fully upwards and resulting in a narrow distance between the scraper and the roller surface. Furthermore, opening the scraper requires loosening the adjusting bolt with a wrench, which is inconvenient due to the limited space.

[0042] In addition, the scraper is equipped with a crossbeam limiting structure, which completely restricts the position of the scraper when the limiting bolt is held in place by the crossbeam. If there are foreign objects other than soil such as stones or branches, the scraper cannot be adjusted accordingly, which can easily lead to damage to the scraper.

[0043] The following is combined Figure 1 , Figure 2 , Figure 3 and Figure 4 The present application will be described in detail with reference to specific embodiments.

[0044] On the one hand, this application provides a sludge scraping device, including: a mounting base 100, which is used to connect with a road roller 10. For example, the mounting base 100 is provided with mounting holes, and the mounting base 100 is connected to the road roller 10 through the mounting holes. For example, bolts or studs are threadedly connected to the road roller 10 through the mounting holes, so that the mounting base 100 and the road roller 10 are detachably connected, which is convenient for installation at different positions of the road roller 10. For example, the mounting base 100 can be located above, in front of or behind the roller of the road roller 10, and this application does not limit this.

[0045] The first mounting component 200 is hinged to the mounting base 100; the scraper component 300 is connected to the first mounting component 200. For example, the first mounting component 200 is rotatably mounted on the mounting base 100, so that the relative position of the first mounting component 200 and the mounting base 100 can be adjusted. The first mounting component 200 is connected to the scraper component 300, so that by adjusting the rotational position of the first mounting component 200 and the mounting base 100, the scraper component 300 can be driven to rotate to move closer to or away from the surface of the roller of the road roller 10.

[0046] This application does not limit the connection method between the scraper 300 and the first mounting part 200. It can be a detachable connection, such as a detachable connection using fasteners (e.g., bolts). Specifically, the first mounting part 200 is connected to the scraper 300 via a U-shaped plate. The first mounting part 200, the U-shaped plate, and the scraper 300 all have threaded holes. The U-shaped plate is clamped on both sides of the scraper 300. Bolts pass sequentially through one side of the U-shaped plate, the scraper 300, the other side of the U-shaped plate, and the first mounting part 200, achieving a secure connection and reducing the possibility of the scraper 300 falling off during scraping. Alternatively, the connection method between the scraper 300 and the first mounting part 200 can also be welding.

[0047] An elastic element 400 is provided, one end of which is connected to the first mounting member 200, and the other end of which is connected to the mounting base 100. The first mounting member 200 is rotatable relative to the mounting base 100, so that the scraper 300 can switch between a scraping position and an open position. In the scraping position, such as... Figure 1 As shown, the scraper 300 is used to abut against the surface of the wheel component 20, and the center of the elastic member 400 is located below the hinge point between the first mounting member 200 and the mounting base 100; in the open position, as Figure 2 As shown, the center of the elastic element 400 is located above the hinge point between the first mounting member 200 and the mounting base 100, and keeps the scraper 300 away from the surface of the wheel component 20. The elastic element 400 can be a spring, a tension spring, or a torsion spring, and this application does not limit it to any of these.

[0048] Mounting base 100 is fixed to the frame of roller 10. First mounting member 200 is rotatably connected to mounting base 100 via hinge point. Scraper 300 is mounted at the end of first mounting member 200. Elastic member 400 (such as tension spring) is connected at one end to first mounting member 200 and at the other end to mounting base 100. Under external force, the first mounting member 200 is driven to rotate around the hinge point to the scraping position. At this time, elastic member 400 is located below the hinge point. Elastic member 400 provides downward force to scraper 300, keeping the lower edge of scraper 300 in contact with the surface of wheel component 20, thus performing the scraping function. Alternatively, the first mounting member 200 is driven to rotate around the hinge point to the open position. At this time, the center of elastic member 400 is located above the hinge point. Elastic member 400 provides upward force to scraper 300. The upward force moves scraper 300 away from the surface of wheel component 20 and keeps scraper 300 in the open position. In this application, the hinge point between the first mounting member 200 and the mounting base 100 is within the rotation range of the elastic member 400, allowing the tension spring to pull the first mounting member 200 upwards or downwards. This allows the scraper member 300 to be manually lifted and held in an open state, and manually pressed down and held in a scraping state. It should be noted that this application does not limit the structure of the scraper blade; for example, the scraper member 300 can be a scraper blade.

[0049] It is understandable that switching between the aforementioned scraping position and open position only requires external force (such as manual or hydraulic mechanical action) to move the scraper 300 up and down for adjustment. Compared with the prior art, in this application, when manually moving the scraper 300 up and down, the scraper 300 can be lifted without the aid of tools, and there is no need to use a wrench to tighten the adjusting bolt to lift the scraper 300. Moreover, compared with the prior art, the crossbeam limiting structure has been eliminated, avoiding the defect that the scraper 300 is easily damaged when encountering hard objects under the crossbeam limiting condition.

[0050] Moreover, when the roller encounters a large hard object, the scraper 300 can be impacted and lifted to the open position, and the elastic element 400 passes over the hinge point and is located above it, pulling the scraper 300 away from the roller surface and keeping it suspended.

[0051] In one possible implementation, the sludge scraping device in this embodiment includes a mounting base 100 comprising a first body 110, a second body 120, and a hinge shaft 130 rotatably disposed within the first body 110. A first mounting member 200 is connected to the hinge shaft 130. The end of the first mounting member 200 facing the sludge scraper 300 has a first connecting portion 201. The first connecting portion 201 and the second body 120 are respectively disposed on opposite sides of the hinge shaft 130 and respectively connected to the two ends of the elastic member 400. The first mounting member 200 rotates around the hinge shaft 130, causing the first connecting portion 201 to rotate relative to the second body 120, so that the center of the elastic member 400 is located below or above the hinge shaft 130.

[0052] Specifically, the first mounting component 200 is a bent plate. The center of the first mounting component 200 is fixedly connected to the hinge shaft 130. The rotation of the hinge shaft 130 drives the first mounting component 200 to rotate. The end of the first mounting component 200 facing the scraper 300 is detachably connected to the scraper 300. For example, one end of the bent plate is detachably connected to the scraper 300 by bolts. The side of the bent plate away from the scraper 300 has a first connecting part 201. The first connecting part 201 can be a connecting shaft. The first connecting part 201 is used to connect to one end of the elastic member 400.

[0053] The elastic element 400 is connected at both ends to the second body 120 and the first connecting portion 201, which are located on both sides of the hinge shaft 130. When the first mounting member 200 rotates, the first connecting portion 201 swings around the second body 120: in the scraping position, the first connecting portion 201 moves downward, and the center of the elastic element 400 is below the hinge shaft 130; in the open position, the first connecting portion 201 moves upward, and the center of the elastic element 400 moves above the hinge shaft 130. It can be understood that the first connecting portion 201 and the second body 120 are located on the extension line of the tension direction of the elastic element 400. For example, the second body 120 has a second connecting portion 121, and the elastic element 400 forms a fixed end during rotation by connecting to the second connecting portion 121. In this embodiment, the switching between the two states and self-locking can be achieved by the tension of the elastic element 400 and the rotation of the first mounting member 200, without the need for an additional locking mechanism.

[0054] The second body 120 is connected to the first body 110, and the second body 120 is located on the side of the first body 110 opposite to the scraper 300. The first body 110 has a mounting through hole 111, such as... Figure 3 As shown, the hinge shaft 130 is rotatably disposed within the mounting through hole 111. The first mounting member 200 is connected to the hinge shaft 130 within the mounting through hole 111 to form a hinge point. Both ends of the first mounting member 200 pass through the mounting through hole 111 and extend outward away from the mounting through hole 111. The first mounting member 200 is a bent mounting plate. The end of the mounting plate facing the scraper 300 has a first connecting portion 201. The two ends of the elastic member 400 are respectively connected to the second body 120 and the first connecting portion 201. For example, the first mounting member 200 is a mounting plate that passes through the mounting through hole 111 and is connected to the hinge shaft 130. The rotation of the hinge shaft 130 drives the mounting plate to rotate.

[0055] The first mounting component 200 rotates around the hinge shaft 130, causing the first connecting part 201 to rotate relative to the second body 120. In the open position, the center of the elastic element 400 is located above the hinge shaft 130, or in the mud-scraping position, the center of the elastic element 400 is located below the hinge shaft 130.

[0056] In one possible implementation, the sludge scraping device in this application embodiment has a first body 110 with a mounting through hole 111, a hinge shaft 130 rotatably disposed in the mounting through hole 111, and two ends of the first mounting member 200 passing through the mounting through hole 111 from the hinge shaft 130 to form two extensions 210 located on opposite sides of the first body 110, and the extensions 210 disposed toward the sludge scraping member 300 have a first connecting portion 201.

[0057] The hinge shaft 130 passes through the mounting through hole 111 of the first body 110. The first mounting member 200 is a long strip-shaped bent plate that passes through the through hole, with both ends extending out of the through hole to form two extension sections 210, namely a front extension section 210 and a rear extension section 210, as shown below. Figure 4 As shown. The front extension 210 connects to the scraper 300 and has a first connecting part 201, while the rear extension 210 has a limiting structure. When the hinge shaft 130 rotates, it drives the entire bending plate to rotate, causing the front extension 210 to drive the scraper 300 to rise and fall. The rear extension 210 cooperates with the mounting base 100 (such as the fixing plate 140 of the mounting base 100) to limit the movement and prevent the scraper 300 from tilting upwards excessively.

[0058] In some embodiments, the mounting base 100 further includes a fixing plate 140, which is connected to the first body 110 and located below the hinge shaft 130. In the open position, the fixing plate 140 abuts against the first mounting member 200 to limit the rotational position of the first mounting member 200. The fixing plate 140 is obliquely welded to the bottom of the first body 110 and located below the hinge shaft 130. When the scraper 300 is in the open position, the rear extension 210 of the first mounting member 200 presses down and abuts against the upper surface of the fixing plate 140, limiting the angle of further rotation and preventing the scraper 300 from tilting upwards excessively.

[0059] In one possible implementation, the sludge scraping device in this application embodiment has a fixed plate 140 that is inclined and the inclined direction is toward the extension 210 that is disposed away from the sludge scraper 300. The extension 210 has a bent portion 211 that is inclined toward the fixed plate 140. When in the open position, the bent portion 211 is used to abut against the fixed plate 140, thereby preventing the sludge scraper 300 from tilting upwards excessively.

[0060] Understandably, the portion of the first mounting member 200 located behind the hinge shaft 130 has a bend 211, which limits its movement in the open position, preventing the scraper 300 from completely tilting upwards under tension. For example, the fixing plate 140 is inclined towards the rear extension 210. The end of the rear extension 210 has a bend 211 that matches the inclination angle of the fixing plate 140. In the open position, the bend 211 fits against the upper surface of the fixing plate 140, forming a surface contact limit.

[0061] In one possible implementation, the mud scraping device in this application embodiment further includes an adjusting member 500, which is inserted into the first mounting member 200 and abuts against the mounting base 100 at the mud scraping position. The adjusting member 500 moves toward the mounting base 100 to adjust the relative position of the mud scraper 300 and the surface of the wheel component 20.

[0062] The adjusting member 500 extends laterally through the threaded hole in the middle of the first mounting member 200. In the sludge scraping position, the end of the adjusting member 500 abuts against the fixing plate 140 of the mounting base 100. Tightening the adjusting member 500 pushes the first mounting member 200 forward about the hinge axis 130, causing the sludge scraper 300 to press against the roller surface; loosening the adjusting member 500 causes the first mounting member 200 to tilt backward, and the sludge scraper 300 to move away from the roller, creating a gap.

[0063] The adjusting component 500 can be an adjusting screw or a limiting cam. The adjusting component 500 can be an adjusting screw, and the first mounting component 200 has an adjusting hole. The fixing plate 140 of the mounting base 100 is located below the hinge shaft 130. The adjusting screw abuts against the fixing plate 140 through the adjusting hole, adjusting the position of the first mounting component 200 relative to the hinge shaft 130 when in the scraping position. External force is applied, causing the adjusting screw to move towards the mounting base 100, such as by manually rotating and tightening the screw. This moves the adjusting screw towards the fixing plate 140, adjusting the rotation of the first mounting component 200 relative to the mounting base 100, thereby driving the scraper 300 closer to the surface of the wheel component 20 to fit tightly against the surface of the wheel component 20. External force is applied, causing the adjusting screw to move away from the mounting base 100, such as by manually rotating and loosening the screw. This moves the adjusting screw away from the fixing plate 140, adjusting the rotation of the first mounting component 200 relative to the mounting base 100, thereby driving the scraper 300 away from the surface of the wheel component 20, leaving an appropriate gap.

[0064] Of course, the adjusting member 500 can also be a limiting cam. For example, the limiting cam can be rotatably inserted into the adjusting hole, and its eccentric profile surface selectively abuts against the upper surface of the fixing plate 140; wherein, when the limiting cam is rotated to the point where its long diameter end abuts against the fixing plate 140, the first mounting member 200 is driven to rotate in the forward direction around the hinge shaft 130, so that the scraper 300 fits against the surface of the wheel component 20; when the limiting cam is rotated to the point where its short diameter end abuts against the fixing plate 140, the first mounting member 200 rotates in the reverse direction, so that a gap is formed between the scraper 300 and the surface of the wheel component 20.

[0065] The bent portion 211 of the first mounting member 200 located behind the hinge shaft 130 can also be replaced with a hook structure to achieve limiting. In this embodiment, the application also includes a hook, located on one side of the first mounting member 200, which abuts against the first mounting member 200 to limit its rotational position. Specifically, the hook can be a hook fixed to the side of the mounting base 100. In the open position, the rear extension 210 of the first mounting member 200 is hooked by the hook, forming a mechanical hard limit to prevent excessive tension in the elastic member 400 from causing the scraper member 300 to lift excessively.

[0066] In one possible implementation, the mud scraping device in this application embodiment includes at least two elastic elements 400, which are respectively disposed at opposite ends of the first mounting member 200.

[0067] This application includes at least two elastic elements 400, which are respectively disposed at opposite ends of the first mounting member 200. That is, one scraper 300 corresponds to two elastic elements 400. The two elastic elements 400 are spaced apart along the length of the first connecting portion 201. A connecting shaft is provided on the side of the first connecting portion 201 facing the roller surface. One end of each of the two elastic elements 400 is connected to the connecting shaft. Another connecting shaft is provided on the side of the second connecting portion 121 facing the first body 110. The other end of each of the two elastic elements 400 is connected to the other connecting shaft. The two elastic elements 400 enhance the tension on the scraper 300, regardless of whether the scraper 300 is in the open position or the scraping position.

[0068] This application also provides a road roller 10, including a body and a sludge scraper device of any of the above embodiments disposed on the body.

[0069] The road roller 10 includes a body with rollers. Scraping devices can be positioned above the rollers to scrape the upper half of the rollers, or below the rollers to scrape the lower half. This application does not limit the number of scraping devices; one roller can correspond to one scraping device, or one roller can correspond to two scraping devices. For example, one roller can correspond to two scraping devices. The two scraping devices are located on the upper and lower halves of the same roller, respectively, and their scraping directions are opposite. Alternatively, the two scraping devices are located on the upper halves of the same roller, and their scraping directions are the same.

[0070] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein.
