Description

Technical Field

[0001] The utility model relates to the technical field of tailing waste processing, in particular to a cone crusher for tailing waste. Background Art

[0002] The part of the product of the sorting operation in mineral processing that has a low content of useful target components and cannot be used for production is called tailings. Under the current technical and economic conditions, it is not suitable for further sorting. However, with the development of production science and technology, the useful target components may have economic value for further recycling.

[0003] At present, in the process of tailings waste processing, cone crushers are used to crush the waste. After the waste is put into the feed port of the cone crusher, when the cone crusher hammer rotates, a large amount of waste ore will splash out from the feed end, which will cause certain safety hazards. At the same time, due to the frequent feeding of the feed end of the cone crusher, the feed end of the cone crusher will be impacted and deformed, thereby greatly reducing the service life of the cone crusher. Therefore, we proposed a cone crusher for tailings waste to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figures 1-5 A cone crusher for tailings waste includes a crusher pressure-resistant shell 1, two feeding semi-annular funnels 2, and a cone crusher body 3 arranged inside the crusher pressure-resistant shell 1.

The position distribution diagram of the plurality of anti-slip strips 19 is shown in FIG. Figure 5 As shown, the purpose of setting the anti-slip strip 19 is to prevent the two feeding semi-annular funnels 2 from rotating on the top of the crusher pressure-resistant shell 1;

[0021] Two feeding semi-annular funnels 2 are fixedly arranged on the top of the crusher pressure-resistant shell 1 by multiple cap bolts. The top and side walls of the crusher pressure-resistant shell 1 are respectively provided with a feeding port 4 and multiple discharging ports 5. The bottom of the crusher pressure-resistant shell 1 is rotatably connected to a main shaft 6 fixedly connected to the bottom of the cone crushing hammer body 3. The outer wall of the crusher pressure-resistant shell 1 is rotatably connected to a transmission shaft 7. The main shaft 6 and the transmission shaft 7 are connected by a large and small bevel gear assembly.

[0022] Two limit rings 8 are fixedly connected to the outer wall of the crusher's pressure-resistant shell 1, and two limit slots 9 that fit with the limit rings 8 are opened on the inner wall of the feeding semi-annular funnel 2. A rotating groove 10 is opened on the inner wall of the feeding semi-annular funnel 2. A rotating shaft 11 is rotatably connected to the inner wall of the rotating groove 10. A curved anti-collision blanking plate 12 is fixedly connected to the outer wall of the rotating shaft 11. The shape of the curved anti-collision blanking plate 12 is as shown in FIG. Figure 4 As shown, the position of the curved anti-collision blanking plate 12 is as follows Figure 2 As shown;

[0023] An arc-shaped hole 13 coaxial with the rotating shaft 11 is provided on the inner side wall of the feeding semi-circular funnel 2. An arc-shaped sliding rod 14 is fixedly connected to the bottom of the curved surface anti-collision blanking plate 12. The outer side wall of the arc-shaped sliding rod 14 on the same side is slidably connected to the inner side wall of the arc-shaped hole 13. A bending spring 15 is slidably connected to the inner side wall of the arc-shaped hole 13. The two ends of the bending spring 15 are respectively fixedly connected to the inner side wall of the arc-shaped hole 13 and the end of the arc-shaped sliding rod 14.

[0024] The functional principle of the present utility model can be described through the following operation method: When it is necessary to install two feeding semi-circular funnels 2 on the top of the crusher pressure-resistant housing 1, one worker needs to fit the feeding semi-circular funnel 2 against the side wall of the crusher pressure-resistant housing 1, so that the two limit card slots 9 on the inner wall of the feeding semi-circular funnel 2 fit on the limit ring 8, and at the same time, the anti-slip strip 19 on the inner top of the feeding semi-circular funnel 2 also fits on the top of the crusher pressure-resistant housing 1;

[0025] Then, install another feeding semi-circular funnel 2 on the top of the crusher pressure-resistant housing 1 as well, and use multiple cap screws to fix the two feeding semi-circular funnels 2 on the top of the crusher pressure-resistant housing 1. The initial position of the device is as Figure 1 shown. Use an external motor to connect the transmission shaft 7 through a belt, which is convenient for the external motor to drive the main shaft 6 and the conical crushing hammer body 3 thereon to rotate through the transmission shaft 7 and the large and small bevel gear assemblies, so as to enable the conical crushing hammer body 3 to perform crushing work on the tailings waste;

[0026] When feeding tailings waste into the feeding semi-circular funnel 2, when the tailings waste falls on the curved surface anti-collision blanking plate 12, it will drive the curved surface anti-collision blanking plate 12 to rotate downward. When the curved surface anti-collision blanking plate 12 rotates, it will allow the tailings waste to enter the crusher pressure-resistant housing 1, and the rotating conical crushing hammer body 3 will perform crushing work. When the curved surface anti-collision blanking plate 12 rotates under pressure, it will drive the rotating shaft 11 to rotate, and at the same time, the curved surface anti-collision blanking plate 12 will drive the arc-shaped sliding rod 14 to rotate. The outer wall of the arc-shaped sliding rod 14 will slide on the inner wall of the arc-shaped hole 13, causing the bending spring 15 to be compressed. When there is no tailings waste feeding at the top of the curved surface anti-collision blanking plate 12, the rebound of the bending spring 15 will make the curved surface anti-collision blanking plate 12 return to the initial position.

[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
