[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0019] The utility model provides Figure 1-4 The integral spindle nut of a cone machine shown in the figure includes a mounting column 1, a material dividing column 2 for material dividing is arranged at the top of the mounting column 1, a connecting column 3 for connecting with the material dividing column 2 is arranged at the top of the mounting column 1, a mounting groove 4 for connecting with the spindle is opened at the bottom of the mounting column 1, a rotating groove 8 for rotating the connecting column 3 is opened at the top of the connecting column 3, a material dividing trough 6 for placing materials is opened at the top of the material dividing column 2, and a material guide trough 7 for discharging accumulated materials is opened at the bottom of the material dividing trough 6.
[0020] Specifically, the top of the mounting column 1 is fixedly connected to the bottom end of the connecting column 3, the top of the connecting column 3 is fixedly connected to the bottom end of the dividing column 2, the mounting column 1 and the dividing column 2 are cylindrical, the connecting column 3 is truncated cone-shaped, the mounting groove 4 is cylindrical, and the inner wall of the mounting groove 4 is provided with a thread for connecting to the end of the main shaft, and the rotating groove 8 passes through the top of the connecting column 3, and the rotating groove 8 is used to insert a long rod to drive the connecting column 3 to rotate.
[0021] Furthermore, the connecting column 3 is an inverted cone, the top size of the connecting column 3 corresponds to the size of the material dividing column 2, and the bottom size of the connecting column 3 corresponds to the size of the mounting column 1. The mounting column 1, the connecting column 3 and the material dividing column 2 adopt an integrated processing and molding technology, thereby eliminating the original material dividing plate and bolts, thereby simplifying the parts. By opening a mounting groove 4 at the bottom of the mounting column 1 and threadedly interlaced with the top of the mounting column 1, the mounting column 1, the connecting column 3, the material dividing column 2 and the main shaft can be connected, so that the mounting column 1, the connecting column 3 and the material dividing column 2 form an integral main shaft nut. During the installation of the main shaft nut, a long rod with a size smaller than the diameter of the rotating groove 8 is inserted into the interior of the rotating groove 8, and then the long rod is rotated. The long rod drives the connecting column 3 to rotate synchronously, and the connecting column 3 drives the mounting column 1 to rotate synchronously, so that the thread on the inner wall of the mounting groove 4 is engaged with the thread on the outer wall of the top of the main shaft, so that the mounting column 1 and the main shaft form a threaded connection. In this way, the connection and installation of the main shaft nut and the main shaft can be completed.
[0022] Specifically, one end of the material guiding groove 7 is connected to the bottom of the inner wall of the material distributing groove 6 , and the other end of the material guiding groove 7 is connected to the outer wall of the top of the connecting column 3 .
[0023] Furthermore, the dividing trough 6 is opened in the middle of the dividing column 2. By placing materials inside the dividing trough 6, when the cone crusher is in use, the falling materials can collide with the materials inside the dividing trough 6 without directly colliding with the dividing column 2, thereby reducing the wear of the dividing column 2. At the same time, the dividing trough 6 can play the role of the original dividing plate. When the materials are fed by other feeding equipment and pass through the dividing column 2 again, the rotating dividing column 2 uses centrifugal force to evenly spread the crushed materials on the surrounding crushing walls, so that a "stone-to-stone" crushing effect is generated between the materials, thereby controlling the uniformity of the material crushing process and improving the service life of the machine's wearing parts. The guide trough 7 is a curved arc trough, and the concave surface of the guide trough 7 faces the side away from the mounting column 1. The guide trough 7 is opened There are multiple material guide grooves 7 which are evenly spaced and annularly distributed around the bottom of the distribution trough 6. The two ends of the material guide grooves 7 respectively penetrate the edge of the bottom of the distribution trough 6 and the outer wall of the top of the connecting column 3. During the use of the distribution column 2, large materials will gradually be thrown out of the distribution trough 6 as the distribution column 2 rotates and the material falls. As the crushing work continues, a large amount of crushed and small materials will accumulate at the bottom of the distribution trough 6. Under the centrifugal force of the rotation of the distribution column 2, the crushed and small materials will accumulate on the bottom edge of the distribution trough 6. When the crushing work is completed, it is necessary to clean the crushed and small materials accumulated in the distribution trough 6. Through the multiple material guide grooves 7 arranged in an annular manner, when the distribution column 2 rotates, the crushed and small materials will slide out of the distribution trough 6 through the material guide grooves 7, thereby reducing the accumulation of crushed and small materials.
[0024] Specifically, an annular groove is formed at the bottom of the mounting column 1 , and a sealing ring 5 for sealing a connection gap of the mounting column 1 is fixedly connected to the inner wall of the annular groove.
[0025] Furthermore, the sealing ring 5 is a rubber ring. After the mounting column 1 is rotated and connected to the main shaft, long-term use of the crusher will cause a large amount of dust and fine particles to accumulate inside the connecting gap at the bottom end of the mounting column 1. As the dust or fine particles enter the interior of the mounting groove 4, it will cause the threads to get stuck, which is not conducive to the rotation of the main shaft nut. Therefore, the sealing ring 5 is extruded and deformed to isolate the mounting groove 4 from the outside, which can prevent dust and fine particles from entering the interior of the mounting groove 4 and ensure the rotation and disassembly of the main shaft nut.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
