Description

Technical Field

[0001] This utility model relates to the field of bulldozer technology, and more specifically, to a standard bulldozer for farmland construction. Background Technology

[0002] Standard farmland refers to high-quality arable land formed through land consolidation and construction, characterized by concentrated and contiguous areas, complete facilities, high and stable yields, sound ecology, strong disaster resistance, and compatibility with modern agricultural production and management methods. Its core indicators include flat and regular plots, fertile and healthy soil, complete irrigation and drainage facilities, convenient and unobstructed roads, a reasonable forest network layout, sufficient power supply, and compliance with mechanized operations. Through the construction of high-standard farmland, my country has effectively improved the quality of arable land and grain production capacity.

[0003] In the process of planning and rectifying standard farmland, bulldozers are needed to control the movement of the bulldozer blades, which push the soil in the farmland to level it and divide it into ridges.

[0004] Traditional bulldozer blades often have protective panels welded to their surfaces to enhance overall wear resistance. However, welding makes it difficult to replace these panels when damaged. Furthermore, most existing bulldozer blades have replaceable slats secured to the bottom with bolts, facilitating the replacement of easily worn parts. However, this method of bolting the entire slat requires replacing the entire blade, preventing the replacement of damaged sections. This results in high maintenance costs and inconvenience for existing bulldozer blades. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a standard bulldozer for farmland construction, which has the following beneficial effects:

[0019] 1. This utility model, through its modular and detachable structural design, significantly reduces the maintenance cost of bulldozer blades during standard farmland construction, improves maintenance efficiency, reduces time wasted on equipment maintenance during construction, and enhances overall construction efficiency. The protective panel uses a combination of mounting strips and mounting grooves, secured with a first locking bolt, avoiding the inconvenience of traditional welding methods and allowing for quick disassembly and replacement after damage. The protective base plate is composed of multiple independent protective teeth, secured by the limiting engagement of connecting strips and connecting grooves and a second locking bolt, enabling partial replacement rather than complete replacement, significantly reducing material waste. The protective side plates are secured by the engagement of teeth and grooves and a third locking bolt, enhancing side protection and facilitating individual maintenance. This modular design allows for independent maintenance of each component, effectively reducing maintenance costs throughout the equipment's lifecycle.

[0020] 2. This utility model significantly improves the installation efficiency and stability of the bulldozer blade through a multi-limiting structure. The connecting end of the protective tooth precisely aligns with the interlocking groove in the installation slot via an interlocking strip, and is fixed with the second locking bolt to ensure its impact resistance. The locking teeth of the protective side plate engage with the locking grooves of the base and the protective panel, forming a lateral constraint to prevent loosening during bulldozing operations. The guide top plate quickly aligns with the positioning groove of the base via a positioning block, and is reinforced with a fourth locking bolt, simplifying the installation process and enhancing the top's resistance to deformation. These designs, while ensuring convenient disassembly, significantly improve the overall structural load-bearing reliability through the dual protection of mechanical interlocking and bolt fixing.

[0021] 3. This utility model optimizes the farmland construction performance of bulldozers through structural innovation. The wear-resistant surface layer at the bottom of the protective teeth extends the life of vulnerable parts and reduces replacement frequency. The arc-shaped inclined design of the guide top plate effectively prevents soil from overflowing from the top, avoiding contamination of the rear hydraulic components. The material-blocking function of the protective side plates reduces lateral soil leakage and improves bulldozing efficiency. The split-type protective panel and protective teeth design allows for differentiated replacement based on the degree of wear, enabling differentiated maintenance. These improvements, while ensuring equipment durability, significantly enhance the land preparation accuracy and operational continuity in standard farmland construction, making it particularly suitable for the needs of large-scale mechanized farmland construction.

[0041] In summary:

[0042] When the bulldozer blade 2 of the bulldozer 1 needs to be inspected and maintained during the construction of standard farmland, this utility model can realize convenient and quick partial disassembly gap, realize differentiated maintenance, and reduce maintenance costs while improving the convenience of inspection and maintenance.

[0043] In this invention, when installing the protective panel 4, the mounting slide 5 on the back of the protective panel 4 is slid from the side of the base 3 into the corresponding mounting groove 6. The cooperation between the mounting slide 5 and the mounting groove 6 can limit the vertical movement of the protective panel 4 on the base 3. Then, the protective panel 4 is fixed to the base 3 by the cooperation of multiple sets of first locking bolts 7. In this way, compared with the existing technology that uses welding to fix the protective panel 4 to the base 3, this invention ensures installation stability while facilitating the disassembly and replacement of the protective panel 4.

[0044] This invention features a protective base plate 10 formed by multiple protective teeth 9 along the mounting edge 8 at the bottom of the base 3. This allows for partial disassembly and replacement of the protective base plate 10 when damaged, while maintaining bulldozing performance and reducing equipment maintenance costs. Adjacent protective teeth 9 are connected by connecting strips 11 and connecting grooves 12, thereby increasing the connection strength between the protective teeth 9 and improving the load-bearing capacity during bulldozing. During installation, the protective teeth 9 are pushed upwards from the bottom of the mounting edge 8, causing the connecting end 13 carrying the insertion strip 17 to insert into the corresponding insertion groove 16. This allows the connecting end 13 to be positioned within the corresponding mounting groove 15 and secured by the second locking bolt 14, thus enabling convenient, stable, and rapid installation of the protective tooth 9 on the mounting edge 8. Afterward, adjacent protective teeth 9 are installed according to the above steps, and during installation, the corresponding connecting strip 11 slides into the corresponding connecting groove 12. This improves the mutual restraint effect between adjacent protective teeth 9. Furthermore, during disassembly, after releasing the restraint of the second bolt, the corresponding protective tooth 9 can be directly disassembled downwards, improving the ease of disassembly and replacement.

[0045] After the above installation is completed, the protective side plate 18 is installed on both sides, and the locking teeth 20 are inserted into the corresponding slots 21. Then, it is locked and fixed by the third locking bolt 19. This allows the protective side plate 18 to be stably installed on both sides and to stop the material. At the same time, the protective side plate 18 can improve the installation stability of the protective panel 4. The components are mutually constrained, which strengthens the overall installation stability and facilitates the individual replacement of local components.
