Description

Technical Field

[0001] This invention relates to the field of tracked shovels and loaders, specifically a tracked shovel and loader. Background Technology

[0002] Scrapers are earthmoving and transport machinery widely used in engineering fields such as railways, roads, water conservancy, and power. They can independently complete earthmoving, loading, transporting, unloading, and local compaction and leveling operations. Tracked scrapers are a typical model adapted to complex terrain. Most existing scraper buckets have an integral welded structure. This structure has significant shortcomings in practical use: First, maintenance is difficult. The blade, side plates, and inner walls are in constant contact with materials, resulting in severe wear. Damage requires cutting and welding for repair, which is complex, time-consuming, and the heat input during welding can easily lead to structural deformation or stress concentration. In severe cases, the entire bucket must be scrapped, resulting in high maintenance costs. Second, adaptability to working conditions is poor. Once the bucket material and thickness are fixed, they cannot be changed, making it difficult to flexibly adjust to different operational needs.

[0003] To address the aforementioned issues, Chinese utility model patent CN211472634U proposes a "prefabricated loader bucket," which improves maintenance convenience and adaptability to different working conditions by designing the middle bucket wall panel as a detachable structure, allowing for targeted replacement of bucket wall components. However, this solution still has the following limitations: First, the detachable range is limited; critical components that are also prone to wear, such as the blade plate (main cutting plate), side wall panels, and hinge seats, are still welded and fixed, failing to fundamentally solve the problem of inconvenient maintenance. Second, the disassembly and assembly of each component are independent, lacking a linkage design, resulting in cumbersome and inefficient disassembly and assembly steps. Third, the pin seat is still fixed by welding, and this part also bears alternating loads, making repair extremely difficult after wear.

[0004] Therefore, it is necessary to provide a tracked loader that can more comprehensively and conveniently disassemble and repair various components of the bucket, especially one that can disassemble multiple components such as the blade, side plates, inner blade, and pin seat, and further optimize the disassembly and assembly efficiency to better meet the actual needs of engineering. Summary of the Invention

[0014] As a further embodiment of the present invention: both the outer walls of the fixing plate and the L-shaped plate are provided with toothed grooves, the toothed grooves mesh with the spur gear, one end of the outer wall of the fixing plate is in contact with the inner wall of the first fixing groove, and the outer wall of the fixing rod is in contact with the inner wall of the second fixing groove.

[0015] As a further embodiment of the present invention: the outer wall of the first connecting seat is provided with a through groove for the insertion of the fixing plate, and the inner wall of the second connecting seat is fixedly connected with a limiting rod, the limiting rod passing through the fixing rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The invention achieves full detachability of the main components of the bucket, significantly improving maintenance convenience. The main shovel plate, inner shovel plate, blade plate, side plates, first pin seat, and second pin seat are all designed as independent detachable components. Each component is detachably connected to the main shovel plate via a connecting mechanism (positioning plate and positioning groove, cylinder and round hole, connecting plate and connecting groove) and an installation mechanism. When any wear-prone part, such as the blade plate, side plates, inner wall, or pin seat, is damaged, only that single component needs to be disassembled and replaced. Unlike existing technologies (CN211472634U), there is no need to cut and weld the welded structure for repair, nor is it necessary to scrap the entire bucket. This fundamentally reduces maintenance difficulty and cost, and extends the overall service life of the bucket.

[0017] 2. The linkage locking mechanism significantly improves disassembly and assembly efficiency. Compared to existing technologies such as CN211472634U, where the disassembly and assembly of each component are independent and the steps are cumbersome, this invention, during the side plate installation process, uses a vertical plate to push a fixing plate into the first fixing groove to lock the first pin seat. Simultaneously, the fixing plate, via a spur gear, drives an L-shaped plate, which in turn pushes a fixing rod through a connecting rod to engage with the second fixing groove to lock the second pin seat. This linkage design ensures that the side plate installation action synchronously locks the pin seat, effectively simplifying the disassembly and assembly steps and improving maintenance efficiency.

[0018] 3. Flexible adaptation to different working conditions. The modular bucket of this invention can be flexibly assembled by selecting inner shovel plates, blade plates and other components of different materials, thicknesses or surface characteristics according to different working conditions. It can ensure the working strength of the bucket under high-intensity working conditions, and select lightweight components to reduce energy consumption and improve working efficiency under general working conditions. It overcomes the defects of the integral welded bucket, which has single performance and cannot adapt to diverse working conditions.

[0019] In summary, by setting up an assembled bucket structure, this invention overcomes the technical problems of difficult maintenance and poor adaptability to working conditions of existing integral welded buckets. It also makes up for the shortcomings of existing assembled solutions (such as CN211472634U), such as limited disassembly range, lack of linkage mechanism, and inability to disassemble and assemble pin seats. This provides a more efficient, economical and flexible bucket maintenance solution for tracked loaders. Attached Figure Description

A positioning groove 802 is provided at the end of blade plate 10 near positioning plate 801. Circular holes 803 are symmetrically provided on both sides of inner shovel plate 7. Connecting grooves 804 are symmetrically provided on both sides of main shovel plate 6 and blade plate 10. A cylinder 805 and connecting plate 806 are fixedly connected to the outer wall of side plate 11. The cylinder 805 is used to insert into the inner wall of the circular hole 803. Plate 806 is used to insert into the inner wall of connecting groove 804. Side plate 11 has a groove 807 on the side away from connecting plate 806. Connecting mechanism 8 also includes a first transverse groove 808, which is formed on the outer wall of connecting plate 806 and extends to the inner wall of groove 807. The scraper plate 10 has a second transverse groove 809 inside. A crossbar 810 is slidably connected to the inner walls of the first and second transverse grooves 808 and 809.

A pressing block 818 is slidably connected to the inside of the blocking block 814 on one side of the locking block 819. The pressing block 818 extends out of the blocking block 814.

[0025] In this embodiment: when installing the inner shovel plate 7, the blade plate 10, and the side plate 11, the blade plate 10 is moved to one end of the main shovel plate 6, and the positioning plate 801 is inserted into the positioning groove 802 to position the blade plate 10; then the inner shovel plate 7 is attached to the inner wall of the main shovel plate 6; after completion, the side plate 11 is moved to both sides of the main shovel plate 6. During this process, the connecting plate 806 is inserted into the connecting groove 804, and the cylinder 805... Insert the rod into the round hole 803 to position the inner shovel plate 7, the blade plate 10, and the side plate 11; insert the crossbar 810 into the first horizontal groove 808 and the second horizontal groove 809, and then tighten the screw 812 into the first threaded hole 811. Both rotating blocks 813 are in contact with the inner wall of the groove 807, thereby fixing the side plate 11 to both sides of the main shovel plate 6, and thus fixing the main shovel plate 6, the inner shovel plate 7, the blade plate 10, and the side plate 11. After completion, the blocking block 814 is moved into the inner wall of the groove 807 to block the inner wall of the groove 807.

The pressing block 818 is displaced relative to the blocking block 814 under force. The displacement of the pressing block 818 pushes the locking block 819 to move, which compresses the first spring 820. The displacement of the locking block 819 engages with the rotating block 813, thereby preventing the rotating block 813 from rotating and loosening.

[0026] Please refer to this carefully. Figures 9 to 12 The mounting mechanism 9 includes a vertical plate 901, which is fixedly connected to the top of the side plate 11.

At the same time, the displacement of the fixing plate 909 causes the spur gear 910 to rotate, and the rotation of the spur gear 910 causes the L-shaped plate 911 to move. The displacement of the L-shaped plate 911 drives the fixing rod 913 to move through the connecting rod 912. The fixing rod 913 is engaged in the second fixing groove 907, fixing the second mounting plate 906 in the second connecting seat 903, thus fixing the position of the second pin seat 13.
