Technical Field
[0001] This utility model relates to the field of loader technology, and specifically to a blade structure for a combinable loader. Background Technology
[0002] A loader is a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is primarily used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil. By changing different auxiliary working devices, it can also perform bulldozing, lifting, and loading / unloading operations on other materials such as timber.
[0003] In most cases, the working implement equipped on a loader is the bucket, which is used to dig and transfer materials. As the working implement that directly contacts the working materials, the loader bucket is one of the main wear parts of the loader and is directly related to the operating cost. Loader buckets have a large volume and generally adopt a blade plate made of wear-resistant material welded to the front end of the lower body of the bucket. Then, shovel teeth are installed at equal intervals on the blade plate. The shovel teeth play the role of "pathfinder" in loading operations.
[0004] The existing method of connecting the shovel teeth and the blade plate is by bolts, which results in the fastest wear rate. Wear manifests as shortening in length, thinning in thickness, and even separation of the upper and lower parts, making replacement extremely inconvenient. Furthermore, after prolonged use, the bolt connections rust and become difficult to disassemble, increasing workload. Therefore, there is an urgent need to design a modular shovel structure for loaders to solve these problems. Utility Model Content
[0005] The purpose of this invention is to provide a shovel structure for a loader that can be combined with other loaders, so as to solve the above-mentioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A shovel structure for a combustible loader includes a bucket, a blade plate, and shovel teeth. A mounting cavity is provided on the lower side of the blade plate, and a threaded rod is rotatably mounted within the mounting cavity. A threaded sliding plate is threaded onto the circumference of the middle section of the threaded rod. A movable block is fixedly mounted on one side of the threaded sliding plate, and a connecting rod is fixedly mounted on one side of the movable block. A locking block is provided within the shovel teeth. A locking groove is provided at the bottom of the inner wall of the blade plate, and the locking groove is movably inserted into the locking groove. A connecting groove is provided on one side of the locking block, and the connecting rod is movably inserted into the connecting groove.
[0008] The number of the shovel teeth is several, and the number of the moving block, the plug-in rod and the snap-fit block are all corresponding to the number of the shovel teeth.
[0009] A slot is provided on one side of the shovel tooth, and the shovel tooth is engaged with one side of the shovel blade plate through the slot. The upper side of the inner wall of the slot corresponds to the engaging groove.
[0010] The snap-fit block is disposed in the slot, and a groove is formed on the upper side of the inner wall of the slot. A spring and a support rod are disposed between the snap-fit block and the inner wall of the groove. The support rod is slidably connected to the groove, and the spring is sleeved around the support rod.
[0011] The snap-fit block has a first chamfer on one side, and the blade plate has a second chamfer on one front end, with the first chamfer and the second chamfer cooperating.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] like Figure 1-5 As shown in the figure, the present invention provides a shovel structure for a combinable loader, including a bucket 1, a blade plate 2, and shovel teeth 3. A mounting cavity 20 is provided on the lower side of the blade plate 2, and a threaded rod 4 is rotatably mounted within the mounting cavity 20. A threaded sliding plate 5 is threadedly mounted on the circumferential side of the middle section of the threaded rod 4. A movable block 6 is fixedly mounted on one side of the threaded sliding plate 5, and a connecting rod 7 is fixedly mounted on one side of the movable block 6. A locking block 11 is provided inside the shovel teeth 3. A locking groove 9 is provided at the bottom of the inner wall of the blade plate 2, and the locking groove 9 is movably inserted into the locking groove 9. A connecting groove 12 is provided on one side of the locking block 11, and the connecting rod 7 is movably inserted into the connecting groove 12. The number of shovel teeth 3 is several, and... The number of moving blocks 6, plug rods 7, and snap-fit blocks 11 all correspond to the number of shovel teeth 3. A slot 13 is provided on one side of the shovel teeth 3, and the shovel teeth 3 are snapped onto one side of the shovel blade plate 2 through the slot 13. The upper side of the inner wall of the slot 13 corresponds to the snap-fit groove 9. The snap-fit block 11 is set in the slot 13. A groove 8 is provided on the upper side of the inner wall of the slot 13. A spring 10 and a support rod 14 are provided between the snap-fit block 11 and the inner wall of the groove 8. The support rod 14 is slidably connected to the groove 8. The spring 10 is sleeved on the periphery of the support rod 14. A first chamfer 18 is provided on one side of the snap-fit block 11, and a second chamfer 19 is provided at the front end of one side of the shovel blade plate 2. The first chamfer 18 and the second chamfer 19 cooperate with each other.
[0025] Specifically, in this embodiment, rotating the threaded rod 4 drives the threaded slide plate 5 to move. The movement of the threaded slide plate 5 drives the moving block 6 to move. The movement of the moving block 6 drives the insertion rod 7 to move. The insertion rod 7 moves away from the insertion groove 12 on one side of the locking block 11, thereby releasing the insertion rod 7 from limiting the locking block 11. Then, pulling the support rod 14 causes the support rod 14 to drive the locking block 11 to move upward. The upward movement of the locking block 11 can disengage from the locking groove 9 and retract into the groove 8, thereby releasing the fixation between the locking block 11 and the scraper plate 2. Then, pulling the scraper tooth 3 causes the scraper tooth 3 to disengage from the scraper plate 2, thereby completing the disassembly of the scraper tooth 3. During installation, by aligning the locking groove 13 on one side of the scraper tooth 3 with the scraper plate 2, and then pushing the scraper tooth 3, the first chamfer 18 on one side of the locking block 11 contacts the second chamfer 19. Angle 18 and second chamfer 19 allow the snap-fit block 11 to retract into the groove 8 under pressure. When the snap-fit block 11 moves to correspond with the snap-fit groove 9, the spring force of the spring 10 can drive the snap-fit block 11 to insert into the snap-fit groove 9. Then, the threaded rod 4 is rotated in the opposite direction, causing the threaded slide plate 5 to move. The movement of the threaded slide plate 5 can drive the movement of the moving block 6, which in turn can drive the insertion rod 7 to move. The insertion rod 7 can be inserted into the insertion groove 12 on one side of the snap-fit block 11, thus completing the fixation of the shovel teeth 3. The support rod 14 can provide guidance for the snap-fit block 11 and facilitate the user to pull the support rod 14. The upper side of the support rod 14 is provided with a pull ring, which facilitates the user to pull the support rod 14. The length of the threaded slide plate 5 corresponds to the arrangement length of the shovel teeth, but the length of the threaded slide plate 5 is less than the length of the threaded rod 4 and the mounting cavity 20.
[0026] This utility model provides a shovel structure for a loader that can be combined. The shovel plate 2 has an insertion port 17 on one side. A rotating shaft 15 is rotatably installed in the insertion port 17. One end of the rotating shaft 15 is fixedly connected to one end of the threaded rod 4. The other end of the rotating shaft 15 has an internal hexagonal groove 16.
[0027] In another embodiment of this utility model, when rotating the threaded rod 4, a hex wrench adapted to the internal hexagonal socket 16 is inserted into the internal hexagonal socket 16 through the insertion port 17, and then rotating the hex wrench can drive the threaded rod 4 to rotate. By setting the rotating shaft 15 and the internal hexagonal socket 16 in the insertion port 17, it is possible to avoid the situation where the threaded rod 4 is accidentally touched by external force during the use of the bucket, causing the threaded rod 4 to rotate and drive the threaded slide plate 5 to move, thereby increasing the stability of the shovel structure during use.
[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
