[0006] Preferably, the tool assembly includes a cutter head and a fixing ring, the fixing ring is fixedly connected to the outer wall surface of the connecting shaft, the cutter heads are evenly distributed on the outer wall of the fixing ring, and the angle between the cutter head and the center of the fixing ring is 28°.

[0007] Preferably, the tool assemblies are arranged on the outer wall of the connecting shaft at a staggered angle of 7°.

[0008] Preferably, a circular hole is opened at the center of the connecting shaft, a rectangular position is opened at the center of the connecting shaft directly above the circular hole, and the rectangular position is communicated with the circular hole.

[0009] Preferably, the cutter head, the fixing ring and the connecting shaft are designed as an integrally formed structure.

[0010] Beneficial Effects

[0011] Compared with the existing technology, the beneficial effects of the utility model are:

[0012] The utility model is provided with the above-mentioned scheme. When working, the material is first coarsely crushed and then the connecting shaft is rotated to drive the coarsely crushed material to be gradually crushed backward. The setting of this structure makes the size of the material uniform after being crushed, and has the force effect of dispersed crushing, thereby prolonging the service life of the tool.

[0017] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", "vertical", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore are not to be construed as limiting the present invention. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0019] like Figure 1-2It is a structural schematic diagram of a low-speed crusher tool in a preferred embodiment of the utility model. In this embodiment, a low-speed crusher tool includes a tool 1, wherein the tool 1 includes a connecting shaft 2 and a tool assembly 3, and a plurality of groups of tool assemblies 3 are arranged on the outer wall of the connecting shaft 2. The tool assembly 3 is fixedly connected to the outer wall of the connecting shaft 2, and the tool assemblies 3 are evenly distributed on the outer wall of the connecting shaft 2, and a connecting position 8 is formed between two adjacent tool assemblies 3. The connecting position 8 facilitates the shedding of the crushed solid and prevents the crushed solid from being stuck on the tool 1, and the width of the connecting position 8 is greater than the thickness of the tool assembly 3.

[0020] In this embodiment, the tool assembly 3 includes a cutter head 5 and a fixed ring 4, which is fixedly connected to the outer wall surface of the connecting shaft 2 through the fixed ring 4, and the cutter head 5 is evenly distributed on the outer wall of the fixed ring 4, and the angle between the cutter head 5 and the center of the fixed ring 4 is 28°. The setting of this structure improves the material gripping efficiency of the tool 1, and also improves the solid crushing effect.

[0021] In this embodiment, the tool assembly 3 is arranged on the outer wall of the connecting shaft 2 at a staggered angle of 7°. This structure allows the material to be coarsely crushed first and then the connecting shaft 2 rotates to drive the coarsely crushed material to be gradually crushed backward, so that the size of the crushed material is uniform and has a dispersed crushing force effect, thereby increasing the service life of the tool.

[0022] In this embodiment, a circular hole 6 is opened at the center of the connecting shaft 2, and a rectangular position 7 is opened at the center of the connecting shaft 2 just above the circular hole 6, and the rectangular position 7 is communicated with the circular hole 6. This structural setting facilitates the rotation of the driving device and can stably drive the tool 1 to realize the rotation function.

[0023] In this embodiment, the cutter head 5 and the fixing ring 4 are designed as an integrally formed structure with the connecting shaft 2. This structural arrangement improves the use strength of the cutter 1 and increases its service life.
