Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of tracked excavators, specifically relating to a mud scraping structure for tracked excavators. Background Technology
[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] Tracked excavators are engineering machines that use tracks as their walking device. With the characteristics of large contact area between the tracks and the ground and low ground pressure, they can operate stably in complex terrains such as mud, swamps, mountains, and sand. They are widely used in mining, road construction, earthwork engineering and other scenarios.
[0004] In actual operation of tracked excavators, the working environment is often harsh, frequently encountering complex geological conditions such as mud, sticky sand, and humus. When the excavator moves or operates in such terrain, soil adheres heavily to the machine's surface due to the compaction of the tracks and the contact between the machine and the ground, especially at the chassis and slewing bearing mounting points. The slewing bearing mounting point, located below the cab, is the connecting hub between the upper body and the lower chassis. This area is not only narrow and structurally complex, but also surrounded by numerous precision components such as connecting bolts and seals, making it difficult to clean the soil once it adheres using conventional methods. If cleaning is attempted after the excavator has finished its work, the remaining soil will gradually harden due to exposure to air, forming hard clumps. Currently, cleaning of these areas mostly relies on manual operation, but due to limited space and structural obstructions, effective cleaning is difficult, resulting in low efficiency and the potential for accidental damage to precision components due to improper operation. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a mud scraper structure for tracked excavators. This structure efficiently removes mud, sand, and other deposits from the chassis via a scraper blade, preventing chassis corrosion or mechanical component failure caused by long-term accumulation. It also reduces unnecessary friction and load, protecting the structural integrity of the chassis and related components. Furthermore, the scraper blade engages with the track plates via a locking groove and with the track plate ribs via a first and second positioning block, ensuring secure installation, easy disassembly, and convenient replacement after damage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The side of the mud scraper is provided with a snap-fit groove, which snaps onto the track plate. The upper end of the mud scraper is provided with the first positioning plate and the second positioning plate, which are connected to the mud scraper and snap onto the track ribs on the track plate.
[0008] As a further technical solution, the scraper has an upper surface, a lower surface and two side surfaces. The upper and lower surfaces of the scraper are composed of several planes and inclined surfaces, and both side surfaces of the scraper are planes.
[0009] As a further technical solution, the upper surface of the scraper includes a second plane, a first inclined plane and a third plane, one end of the second plane is the first inclined plane and one end of the first inclined plane is the third plane.
[0010] As a further technical solution, the upper surface of the scraper is used to scrape off the sludge at the upper end of the slewing bearing mounting seat.
[0011] As a further technical solution, the first positioning plate and the second positioning plate are mounted on the third plane.
[0012] As a further technical solution, the lower surface of the scraper includes a fourth plane, a second inclined plane, and a fifth plane, with one end of the fourth plane being the second inclined plane and one end of the second inclined plane being the fifth plane.
[0013] As a further technical solution, the lower surface of the scraper is used to scrape off the sludge on the chassis.
[0014] As a further technical solution, one side of the scraper is a first plane, which is used to scrape off the sludge on the side of the slewing bearing mounting seat.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0025] In actual operation of tracked excavators, the working environment is often harsh, frequently encountering complex geological conditions such as mud, sticky sand, and humus. When the excavator moves or operates in such terrain, soil adheres heavily to the machine's surface due to the compaction of the tracks and the contact between the machine and the ground, especially at the chassis and slewing bearing mounting points. The slewing bearing mounting point, located below the cab, is the connecting hub between the upper body and the lower chassis. This area is not only narrow and structurally complex, but also surrounded by numerous precision components such as connecting bolts and seals, making it difficult to clean the soil once it adheres using conventional methods. If cleaning is attempted after the excavator has finished its work, the remaining soil will gradually harden due to exposure to air, forming hard clumps. Currently, cleaning of these areas mostly relies on manual operation, but due to limited space and structural obstructions, effective cleaning is difficult, resulting in low efficiency and the potential for accidental damage to precision components due to improper operation.
[0026] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a mud-scraping structure for a tracked excavator, such as... Figure 1 As shown, it includes a scraper, a first positioning plate 12 and a second positioning plate 13. The scraper has a snap-fit groove 14 on its side, which snaps onto the track plate 4. The upper end of the scraper is provided with the first positioning plate 12 and the second positioning plate 13. The first positioning plate 12 and the second positioning plate 13 are connected to the scraper and snap onto the track ribs 41 on the track plate 4.
[0027] Specifically, the mud on the chassis 2 and slewing bearing mounting base 5 is scraped off by the upper and lower surfaces of the scraper blade and the first plane 111. The upper surface of the scraper blade removes the mud from the upper end of the slewing bearing mounting base 5, the first plane 111 removes the mud from the side of the slewing bearing mounting base 5, and the lower surface of the scraper blade removes the mud from the chassis 2. This efficiently removes mud, sand, and other adhering substances from the chassis 2, preventing corrosion of the chassis 2 or mechanical component failure caused by long-term accumulation, reducing unnecessary friction and load, and protecting the structural integrity of the chassis 2 and related components. Furthermore, the scraper blade engages with the track plate 4 through the locking groove 14 and with the track plate rib 41 through the first and second positioning blocks, ensuring a secure installation, easy disassembly, and convenient replacement after damage.
[0028] The scraper blade has an upper surface, a lower surface, and two side surfaces. The upper and lower surfaces of the scraper blade are composed of several planes and inclined surfaces, while both side surfaces are flat. Through the multi-faceted collaborative scraping design of the scraper blade, effective cleaning of sludge from key parts of the chassis 2 and the slewing bearing mounting base 5 is achieved.
[0029] The upper surface of the scraper includes a second plane 112, a first inclined plane 113, and a third plane 114. One end of the second plane 112 is the first inclined plane 113, and one end of the first inclined plane 113 is the third plane 114. The upper surface of the scraper is used to scrape sludge from the upper end of the slewing bearing mounting base 5. The lower surface of the scraper includes a fourth plane 115, a second inclined plane 116, and a fifth plane 117. One end of the fourth plane 115 is the second inclined plane 116, and one end of the second inclined plane 116 is the fifth plane 117. The lower surface of the scraper is used to scrape sludge from the chassis 2.
[0030] One side of the scraper is a first plane 111, which is used to scrape away sludge from the side of the slewing bearing mounting seat 5. The other side of the scraper is a sixth plane 118. The sixth plane 118 faces the location of the track plate 4.
[0031] Specifically, the upper surface of the scraper blade is attached to the upper end face of the slewing bearing mounting base 5, and can scrape off the deposited sludge during equipment operation; the vertically set first plane 111 is in close contact with the side of the slewing bearing mounting base 5, which can effectively peel off the sticky mud and sand adhering to the side and prevent such debris from accumulating; while the lower surface of the scraper blade cooperates with the chassis 2, and through parallel contact with the surface of the chassis 2, it can effectively scrape off the sludge on the upper surface of the chassis 2.
[0032] To avoid the problems of rust and oxidation of metal parts of chassis 2 caused by long-term sludge coverage, and to avoid the reduction of structural strength caused by rust, the service life of chassis 2 is extended; to remove impurities between mechanical moving parts, effectively prevent abnormal wear caused by sand and gravel during the operation of parts, reduce unnecessary friction resistance and equipment load, and make the mechanical operation smoother and more stable.
[0033] Specifically, depending on the requirements of different models, a suitable scraper model can be selected or its parameter settings (such as plate shape) can be adjusted to be compatible with various specifications of tracked excavators and meet the needs of diverse application scenarios. Structurally, it is necessary to ensure that the scraper can effectively remove mud without damaging the chassis 2.
[0034] The first positioning plate 12 and the second positioning plate 13 are installed on the third plane 114.
[0035] Specifically, the scraper blade is designed to be both stable and convenient to install. The snap-fit groove 14 matches the shape of the track plate 4, enabling quick snap-fit positioning. The tight engagement of the first and second positioning blocks with the track plate ribs 41 forms a multi-fixing structure, ensuring that the scraper blade will not loosen or fall off under complex working conditions such as equipment vibration and high-speed operation.
[0036] Specifically, such as Figure 2 and Figure 3As shown, a slewing bearing mounting seat 5 is provided at the upper end of the chassis 2, and track plates 4 are provided at both ends of the chassis 2. A sludge scraping structure 1 is installed on each of the track plates 4 at both ends. The track plates 4 are moved by the cooperation of the support roller 6 and the drive wheel 3, which in turn drives the sludge scraping structure 1 to move relative to the chassis 2 and the slewing bearing mounting seat 5, thereby scraping off the sludge on the chassis 2 and the slewing bearing mounting seat 5.
[0037] During installation, the scraper blade 11 is inserted onto the track plate 4, ensuring that the locking groove 14 on the scraper blade 11 fits snugly against the track plate 4, and that the first and second positioning blocks at the upper end of the scraper blade 11 engage with the track plate rib 41. When maintenance or replacement is required, disassembly can be completed with simple operations without the need for complex tools, significantly shortening maintenance time and reducing maintenance costs. Even in harsh environments such as field operations, quick replacement can be easily achieved, ensuring the continuous and efficient operation of the equipment.
[0038] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
