[0017] 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.

[0018] The utility model provides Figure 1-3The body assembly of a cone machine shown in the figure includes a vertebral body 1, an axle extension 2 is arranged on the top of the vertebral body 1, a bushing assembly is arranged on the outer wall of the vertebral body 1 and the axle extension 2, a spindle nut 3 for fixing the position of the bushing assembly is provided on the top threaded sleeve of the axle extension 2, a pushing assembly for pushing the spindle nut 3 away from the axle extension 2 is provided at the connection between the axle extension 2 and the spindle nut 3, the pushing assembly includes a fixed sleeve 4 fixedly connected to the top of the axle extension 2 and an extension sleeve 5 inserted and connected to the top of the fixed sleeve 4, and a spring 6 for pushing the extension sleeve 5 away from the fixed sleeve 4 is fixedly connected to the inner wall of the bottom end of the fixed sleeve 4.

[0019] Specifically, the cross-section of the shaft extension 2 is set to be a herringbone shape, the extension sleeve 5 is set on the inner wall of the top end of the main shaft nut 3, the end of the spring 6 away from the fixed sleeve 4 is fixedly connected to the inner wall of the top end of the extension sleeve 5, and a limiting member for limiting the rotation of the extension sleeve 5 is set at the connection between the fixed sleeve 4 and the extension sleeve 5.

[0020] It should be noted that the cross-section of the shaft extension 2 is a herringbone shape, the bottom end of the herringbone shape is fixedly connected to the top of the vertebral body 1, and a thread matching the spindle nut 3 is opened on the top. When in use, the spindle nut 3 is sleeved on the thread opened on the top of the shaft extension 2; the inner diameter of the fixed sleeve 4 is matched with the outer diameter of the extension sleeve 5. When in use, the extension sleeve 5 is slidably inserted and connected inside the fixed sleeve 4, and the limiting member is used to limit the rotation of the extension sleeve 5, and at the same time prevent the extension sleeve 5 from moving out of the fixed sleeve 4, and prevent the extension sleeve 5 from rotating with the rotation of the spindle nut 3 when the spindle nut 3 is rotated to fit with the extension sleeve 5, so that when the spindle nut 3 moves to one side of the extension sleeve 5 by rotating, the extension sleeve 5 moves into the fixed sleeve 4, and the spring 6 is squeezed and deformed by the movement of the extension sleeve 5.

[0021] Furthermore, when the spindle nut 3 is threadedly sleeved on the top of the shaft extension 2, the two are pushed by the spring 6, pushing the shaft extension 2 and the spindle nut 3 away from the connection between the two, thereby strengthening the friction between the threads of the threaded connection between the two through the thrust, thereby strengthening the connection between the two and avoiding the situation where the threaded connection becomes loose due to the rotation of the spindle nut 3.

[0022] Specifically, the limiting member includes limiting sliding grooves 7 symmetrically fixedly connected to both sides of the extension sleeve 5 , and sliding blocks 8 are symmetrically provided on both sides of the fixed sleeve 4 , and the limiting sliding grooves 7 are inserted and connected inside the sliding blocks 8 .

[0023] It should be noted that when the extension sleeve 5 moves, the sliders 8 on both sides thereof are driven to move by the extension sleeve 5, so that the sliders 8 move in the limiting slide groove 7. When the sliders 8 move to fit with the inner wall of one side of the limiting slide groove 7, they will be restricted by the limiting slide groove 7 and cannot continue to move.

[0024] Specifically, the bushing assembly includes a first bushing 9 sleeved on the outer wall of the vertebral body 1 , a second bushing 10 is provided on the top of the first bushing 9 , and the second bushing 10 is sleeved on the middle part of the shaft extension 2 .

[0025] It should be noted that, when the cone crusher is working, the internal components are easily worn due to the friction and impact of the materials. The first bushing 9 and the second bushing 10 are used to reduce the wear and tear and extend the service life of the internal components.

[0026] Specifically, a cutting ring 11 is provided on a side of the spindle nut 3 opposite to the second bushing 10 , and the cutting ring 11 is sleeved on the middle part of the shaft extension 2 .

[0027] Furthermore, when installing the bushing assembly, the first bushing 9 is first sleeved on the outer wall of the vertebral body 1, and then the second bushing 10 is sleeved on the outer wall of the shaft extension 2, so that the first bushing 9 and the second bushing 10 are fitted together, and then the cutting ring 11 is set on the top of the second bushing 10, and finally, it is threadedly sleeved on the top of the shaft extension 2 through the spindle nut 3, and the positions of the cutting ring 11, the second bushing 10 and the first bushing 9 are fixed by pressing the spindle nut 3.

[0028] Specifically, a material chute 12 for collecting materials is provided at the top of the spindle nut 3 , and a rotating hole 13 is provided at the middle of the spindle nut 3 .

[0029] It should be noted that the chute 12 opened at the top of the spindle nut 3 is used to collect materials. When the chute 12 is full of materials, when other materials fall to the top of the spindle nut 3, the materials will first contact with the materials in the chute 12, thereby cushioning the falling materials and reducing the impact of the falling materials on the spindle nut 3. The rotating hole 13 is opened to pass through the spindle nut 3. When the spindle nut 3 needs to be rotated, a round rod is passed through the rotating hole 13 to rotate the spindle nut 3.

[0030] 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.
