[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] See also Figure 1 and Figure 2 The utility model provides a dividing plate of a cone crusher, including a main shaft 1, a dividing plate 2 is arranged on the main shaft 1, a mounting structure 3 is arranged on the main shaft 1, the dividing plate 2 is mounted on the upper end of the main shaft 1 through the mounting structure 3, the main shaft 1 is the output shaft of the cone crusher, and the dividing plate 2 can disperse the ore.

[0025] See also Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model provides a cone crusher ore distribution plate, the mounting structure 3 includes a docking block 31, the docking block 31 is rectangular, the docking block 31 is integrally formed on the surface where the main shaft 1 and the distribution plate 2 are connected, and the docking block 31 is connected to the distribution plate 2, and the docking block 31 is used for transmission. The upper end of the main shaft 1 is provided with a plug-in port 32, and the plug-in port 32 is provided with four. The four plug-in port 32 corresponds to the four surfaces of the rectangular docking block 31, so that when the distribution plate 2 is connected to the docking block 31, the plug-in plate 35 integrally formed on the bottom end surface of the distribution plate 2 can be connected to the plug-in port 32, which has the beneficial effect of convenient docking. The main shaft 1 is provided with a bolt port 33, the bolt port 33 is communicated with the plug-in port 32, and a fixing bolt 34 is inserted into the bolt port 33 and threadedly connected thereto, and a bolt hole is opened in the plug-in plate 35. The fixing bolt 34 can be threadedly connected with the bolt hole to realize that the fixing bolt 34 passes through the plug plate 35, thereby improving the stability of the limit. A top plate 36 is provided inside the spindle 1, and the top plate 36 is connected to the spindle 1 in a transverse sliding manner. Top plates 36 are provided at the upper and lower ends of the bolt opening 33, and a top block 37 is provided on the surface of the fixing bolt 34. When the fixing bolt 34 is locked into the spindle 1, the top block 37 can push the top plate 36 and press the top plate 36 on the surface of the plug plate 35, thereby improving the stability of the plug plate 35, so that the plug plate 35 will not shake inside the spindle 1, affecting the stable connection between the fixing bolt 34 and the plug plate 35, and effectively avoiding problems such as wire jamming. The lower end of the outer side of the plug plate 35 is chamfered on the left and right, and the chamfered surface is smooth, so that the plug plate 35 will not be resisted by the top plate 36 when it is inserted into the plug plate opening 32;

[0026] When the bottom end surface of the material distribution plate 2 is in contact with the top end surface of the main shaft 1, the fixing bolts 34 will be aligned with the bolt holes on the plug plate 35, which improves the convenience of installation;
