[0013] Compared with the prior art, the advantages of this utility model are: This utility model has a compact structure and reasonable design. It forms an efficient crushing structure by installing several sets of crushing blade holders in the middle of the crushing roller, connecting columns installed on the top of the blade holders, and crushing blades fixed on the outside, which can fully crush solid waste.

[0014] The crushing roller of this utility model adopts a structure in which the regular prism and the roller are integrally formed, which not only enhances the overall strength and stability, but also the locking external thread on the outer surface of the roller and the locking nut installed on the inner side facilitates the connection and fixation with other equipment.

[0015] The polygonal hollow limiting groove in the middle of the blade holder body of this utility model can accurately fit onto the outside of the regular prism, ensuring the stable installation of the blade holder on the crushing roller. At the same time, the connecting post hole on the inner circumference of the blade holder body and the through-mounted connecting post provide a reliable way to fix the crushing blade.

[0016] The ring structure of the blade holder adjustment ring and the design of the polygonal hollow limiting groove in the middle of the present invention allow it to be flexibly placed between adjacent blade holder bodies. By adjusting the number and position of the blade holder adjustment rings, the gap between adjacent blade holder bodies can be easily adjusted, thereby adapting to the needs of crushing solid waste of different sizes and shapes.

[0018] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Example 1

[0019] A solid waste crushing device for environmental engineering includes a crushing roller 1, a crushing blade holder 2, a blade holder adjusting ring 3, crushing blades 4, and a connecting column 5. Several sets of crushing blade holders 2 are installed in the middle of the crushing roller 1, and the connecting column 5 is installed on the top of the crushing blade holder 2. The crushing blades 4 are fixed on the outside of the connecting column 5. The crushing blade holders 2 are grouped and limited by the blade holder adjusting ring 3.

[0020] The crushing roller 1, crushing blade holder 2, blade holder adjusting ring 3, and connecting column 5 are all made of high-strength stainless steel, and the crushing blade 4 is made of tungsten carbide hard alloy.

[0021] The crushing roller 1 includes a polygonal regular prism 101 located in the middle, and two circular rollers 102 at both ends of the regular prism 101. The rollers 102 and the regular prism 101 are integrally formed. The outer surface of the rollers 102 has locking external threads. The inner side of the rollers 102 is connected to a locking nut 103 by a thread.

[0022] The crusher holder 2 includes a generally annular holder body 201. A polygonal hollow limiting groove 202 is provided in the middle of the holder body 201, and the limiting groove 202 is sleeved on the outside of the regular prism 101. A circular connecting post hole 203 is provided on the inner circumference of the holder body 201, and a connecting post 5 for fixing and locking the crusher 4 is installed through the connecting post hole 203. Several dividing blocks 204 are welded at intervals on both sides of the holder body 201, and the dividing blocks 204 are used to form a certain gap between adjacent holder bodies 201.

[0023] The crushing roller 1 has a polygonal regular prism 101 in the middle, and a polygonal hollow limiting groove 202 is provided in the middle of the cutter holder body 201. The limiting groove 202 is sleeved on the outside of the regular prism 101. This design can effectively limit the movement of the cutter holder body 201 and prevent it from rotating. Moreover, the cutter holder body 201 does not need to be installed with bolts or welding. When disassembling and replacing the crushing blade 4, it can be directly pulled out from the regular prism 101, saving time and effort.

[0024] The crushing blade 4 is placed between adjacent blade holder bodies 201 and sleeved on the outside of the connecting post 5 that passes through the connecting post hole 203; the crushing blade 4 and the connecting post 5 are connected by a high-strength key; the connecting post 5 passes through the connecting post hole 203 of the blade holder body 201, and the two ends of the connecting post 5 are locked and fixed to the outermost blade holder body 201.

[0025] Both ends of the connecting post 5 are locked and fixed to the outermost blade holder body 201. When the crusher blade 4 is disassembled and replaced later, the connecting post 5 can be quickly removed, saving time and effort. The crusher blade 4 and the connecting post 5 are connected by a high-strength key. When the crusher blade 4 is disassembled and replaced later, the crusher blade 4 can be quickly removed, saving time and effort.

[0026] The tool holder adjusting ring 3 has an overall ring structure with a polygonal hollow limiting groove in the middle, which is sleeved on the outside of the regular prism 101. The tool holder adjusting rings 3 are placed in pairs between adjacent tool holder bodies 201 to form a certain gap between adjacent tool holder bodies 201. The tool holder adjusting rings 3 and the dividing block 204 have the same thickness.

[0027] The tool holder adjustment ring 3 can be quickly disassembled and installed on the outside of the right prism 101. The tool holder adjustment ring 3 and the dividing block 204 have the same thickness, which can ensure that the gap between the bottom and top of the tool holder body 201 is the same, thus ensuring the overall stability of the tool holder body 201.

[0028] The crushing roller 1, crushing blade holder 2, blade holder adjusting ring 3, crushing blade 4, and connecting column 5 are combined into an integrated structure and rotate synchronously. Example 2

[0029] like Figure 7-9 As shown, the solid waste crushing device in Embodiment 1 can be placed entirely within the existing crusher housing, directly replacing the older, more advanced crushing rollers. The installation method involves mounting bearing seats at both ends of the crushing roller 1 onto the crusher body. A pulley is mounted at one end of the crushing roller 1, and the pulley is connected to a belt motor via a belt. Two sets of solid waste crushing devices are installed side-by-side to achieve interlocking crushing of solid waste.
