Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment:

[0026] Please refer to Figures 1-6 , this embodiment provides a movable knife plate for a loader, including a main body 1 of the movable knife plate. The main body 1 of the movable knife plate includes a plurality of single knife plates 2 arranged along the length direction. The single knife plates 2 are separable from each other, and a positioning structure is provided between two adjacent single knife plates 2. Since the main body 1 of the movable knife plate is composed of a plurality of single knife plates 2, when a single single knife plate 2 is worn or damaged, only the damaged single knife plate 2 needs to be disassembled and replaced, reducing the maintenance and repair costs.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown in the figure, the single knife plate 2 includes a main knife plate 21 and a secondary knife plate 22 which are respectively arranged on both sides of the loader's hopper. The main knife plate 21 and the secondary knife plate 22 have the same length. The main knife plate 21 includes an installation part 211, a connection part 212 and a cutting edge part 213 which are connected in sequence. The single knife plate 2 formed by the main knife plate 21 and the secondary knife plate 22 is respectively installed on both sides of the loader's hopper, which can protect the installation part of the loader's hopper and avoid problems such as deformation and wear of the installation part of the loader's hopper.

[0028] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, a first hopper installation slot 216 is provided at the installation part 211 of the main knife plate 21, and a second hopper installation slot 221 is provided on the secondary knife plate 22. The combined shape of the first hopper installation slot 216 and the second hopper installation slot 221 is adapted to the installation part of the loader's hopper. A first installation hole 215 communicating with the first hopper installation slot 216 is provided on the main knife plate 21, and a second installation hole 222 communicating with the second hopper installation slot 221 is provided on the secondary knife plate 22. The second installation hole 222 corresponds to the position of the first installation hole 215. The main knife plate 21 and the secondary knife plate 22 are fixedly installed on the installation part of the loader's hopper by bolts passing through the first installation hole 215 and the second installation hole 222. In this embodiment, both the first installation hole 215 and the second installation hole 222 are counterbored holes, which can accommodate the end of the bolt and prevent the bolt from protruding on the surface of the loader's hopper. The provided first hopper installation slot 216 and the second hopper installation slot 221 are used to closely assemble and install the main knife plate 21 and the secondary knife plate 22 with the loader's hopper. By passing bolts through the first installation hole 215 on the main knife plate 21 and the second installation hole 222 on the secondary knife plate 22, it is convenient to tightly install the main knife plate 21 and the secondary knife plate 22 with the loader's hopper.

[0029] In this embodiment, as Figure 6 shown, a secondary knife plate installation groove 217 is provided on one side of the first hopper installation slot 216 on the main knife plate 21. One end of the secondary knife plate 22 is clamped into the secondary knife plate installation groove 217. Two positioning holes 218 are provided on the inner wall of the secondary knife plate installation groove 217. Two positioning posts 223 are fixedly connected to the secondary knife plate 22 and are inserted into the positioning holes 218. When installing the secondary knife plate 22, first install the main knife plate 21 inside the loader's hopper, then install the secondary knife plate 22 outside the loader's hopper, and clamp one end of the secondary knife plate 22 into the installation groove 217. Then, insert the positioning posts 223 on the secondary knife plate 22 into the positioning holes 218 on the main knife plate 21 to position the relative installation position of the secondary knife plate 22 and the main knife plate 21 and ensure the accuracy of the installation position of the secondary knife plate 22 and the main knife plate 21.

[0030] In this embodiment, asFigure 6 As shown, a clamping groove 219 is formed on the inner wall of the auxiliary knife plate mounting groove 217 between two positioning holes 218. A connecting block 224 is fixedly connected to the auxiliary knife plate 22 and is inserted into the clamping groove 219 in a matching manner. When the auxiliary knife plate 22 and the main knife plate 21 are assembled in place, the connecting block 224 on the auxiliary knife plate 22 is inserted into the clamping groove 219 on the main knife plate 21, increasing the connection area between the auxiliary knife plate 22 and the main knife plate 21 and improving the stability of the connection and installation between the auxiliary knife plate 22 and the main knife plate 21. It should be noted that the length of the positioning post 223 is greater than the thickness of the connecting block 224, and the depth of the positioning hole 218 is greater than the depth of the clamping groove 219, so that the positioning post 223 is first inserted into the positioning hole 218, and then the connecting block 224 is inserted into the clamping groove 219, which helps the connecting block 224 to better cooperate with the clamping groove 219.

[0031] In this embodiment, as Figure 3 and Figure 5 shown, the positioning structure includes positioning grooves 2111 formed on one side of the main knife plate 21 and the auxiliary knife plate 22 and positioning protrusions 2110 provided on the other side of the main knife plate 21 and the auxiliary knife plate 22. The positioning protrusions 2110 are used to accommodate the positioning grooves 2111. When multiple knife plate units 2 are assembled, the positioning protrusions 2110 on the main knife plate 21 and the auxiliary knife plate 22 are inserted into the positioning grooves 2111 on the adjacent main knife plate 21 and auxiliary knife plate 22 in a matching manner, improving the integrity of the knife plate units 2 assembled into the movable knife plate body 1, enhancing the stability after the knife plate units 2 are assembled, and effectively preventing misalignment during the assembly of the knife plate units 2.

[0032] In this embodiment, as Figure 2 shown, a plurality of reinforcing ribs 214 are fixedly connected between the mounting portion 211 and the connecting portion 212 of the main knife plate 21. By providing the reinforcing ribs 214, the structural strength of the main knife plate 21 is improved, and the durability of the main knife plate 21 is enhanced.

[0033] Working principle: When in use, install the main blade plate 21 inside the loader hopper, install the secondary blade plate 22 outside the loader hopper, and snap one end of the secondary blade plate 22 into the installation groove 217, so that the positioning post 223 on the secondary blade plate 22 is inserted into the positioning hole 218 on the main blade plate 21 in alignment. Then, pass a bolt through the first installation hole 215 on the main blade plate 21 and the second installation hole 222 on the secondary blade plate 22 to firmly install the main blade plate 21 and the secondary blade plate 22 on the loader hopper. When the secondary blade plate 22 is assembled in place with the main blade plate 21, the connecting block 224 on the secondary blade plate 22 is inserted into the card slot 219 on the main blade plate 21 in alignment, improving the stability of the connection and installation between the secondary blade plate 22 and the main blade plate 21, and completing the installation of one blade plate unit 2. Then, arrange and install multiple blade plate units 2 in sequence according to the above steps. When assembling adjacent blade plate units 2, align and embed the positioning protrusions 2110 on the main blade plate 21 and the secondary blade plate 22 into the positioning grooves 2111 on the adjacent main blade plate 21 and secondary blade plate 22, improving the integrity of the blade plate units 2 assembled into the movable blade plate body 1, enhancing the stability after assembly of the blade plate units 2, and effectively avoiding misalignment during the assembly of the blade plate units 2. Since the movable blade plate body 1 is composed of multiple blade plate units 2, when a single blade plate unit 2 is worn or damaged, only the damaged blade plate unit 2 needs to be disassembled and replaced, reducing the maintenance and repair costs. The blade plate units 2 composed of the main blade plate 21 and the secondary blade plate 22 are respectively installed on both sides of the loader hopper, which can protect the installation part of the loader hopper and avoid problems such as deformation and wear of the installation part of the loader hopper.

[0034] The above embodiments are the preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
