[0001] This utility model relates to a limit device for the upper cover of a crusher, and belongs to the field of crusher technology. Background Technology

[0002] A crusher, also known as a stone crusher, is a pulverizing machine used in the processing of metal and non-metal minerals to break mined raw ore into small particles through compression and bending.

[0003] During crusher maintenance, the top cover needs to be opened via a hydraulic device for repair or replacement of the rotor blades. After hydraulic opening, the center of gravity of the top cover in the open state is supported by the hydraulic cylinder. The entire center of gravity of the top cover is concentrated on the hydraulic cylinder, causing the hydraulic station to be under constant pressure. This prolonged pressure on the hydraulic station causes wear and tear on the cylinder seals and the hydraulic station mechanism.

[0004] Therefore, a limit device for the upper cover of the crusher is proposed. Utility Model Content

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-3 As shown, this utility model embodiment provides a crusher cover limiting device, including a crusher 1, a top cover 2 movably connected to the top of the crusher 1, a flipping mechanism 3 provided on the front side of the crusher 1, the flipping mechanism 3 including a rotating rod 301, a telescopic cylinder 302 and a fixing plate 303, the rear side of the rotating rod 301 is fixedly connected to the front side of the top cover 2, the rear side of the telescopic cylinder 302 is movably connected to the front side of the crusher 1, the bottom of the rotating rod 301 is movably connected to the output end of the telescopic cylinder 302, the rear side of the fixing plate 303 is movably connected to the front side of the crusher 1 through a rotating shaft, a plug 4 is fixedly connected to the front side of the top cover 2, the front side of the plug 4 extends through to the front side of the fixing plate 303, a compression spring 5 is provided on the front side of the fixing plate 303, the compression spring 5 is sleeved on the surface of the rotating shaft, the rear side of the compression spring 5 is fixedly connected to the front side of the fixing plate 303, and the front side of the compression spring 5 is fixedly connected to the rear side of the rotating shaft.

[0028] When the upper cover 2 needs to be opened for use, the telescopic cylinder 302 pulls the rotating rod 301 through the rotation mechanism, causing the upper cover 2 to flip and open for use. The fixing plate 303 can fix the upper cover 2 to prevent loosening when it is closed. By setting the insertion post 4, the insertion post 4 can be accurately inserted into the interior of the fixing plate 303. By using the compression spring 5, when the fixing plate 303 is pulled, the compression spring 5 is compressed, which makes it convenient for the staff to move the fixing plate 303 outward.

[0029] Example 2

[0030] like Figure 4-5 As shown, in one embodiment, a positioning block 6 is fixedly connected to the right side of the crusher 1, and a plug-in plate 7 is fixedly connected to the right side of the upper cover 2. A cavity 8 is opened inside the positioning block 6. A moving rod 9 is movably connected inside the cavity 8 through a rotating shaft. The bottom of the moving rod 9 extends through the cavity 8 to the bottom of the positioning block 6. A connecting rod 10 is movably connected inside the cavity 8. The outer side of the connecting rod 10 contacts the inner side of the moving rod 9. The other side of the connecting rod 10 extends through to the interior of the plug-in plate 7. A compression spring 11 is fixedly connected to the inner side of the connecting rod 10. A plug-in groove 12 is opened on the surface of the plug-in plate 7. The outer side of the connecting rod 10 is movably connected to the interior of the plug-in groove 12.

[0031] By using the positioning block 6 and the plug plate 7, the moving rod 9 is pulled, and the moving rod 9 moves the connecting rod 10, so that the connecting rod 10 moves into the cavity 8, making it convenient for the staff to unfold and use the top cover 2. By setting the plug groove 12, the connecting rod 10 can be accurately inserted into the plug groove 12 when it is plugged and fixed, thereby improving the connection stability between the crusher 1 and the top cover 2.

[0032] When this utility model is in operation: First, the moving rod 9 is pulled outwards simultaneously. The moving rod 9 rotates around the pivot. When the surface of the moving rod 9 presses against the surface of the connecting rod 10, the connecting rod 10 moves inwards at the same time. As the connecting rod 10 moves inwards, it compresses the compression spring 11, causing the connecting rod 10 to move into the cavity 8. At this time, the fixing plate 303 can be pulled outwards. After the fixing plate 303 is pulled out, the telescopic cylinder 302 is activated, causing the telescopic cylinder 302 to retract. The telescopic cylinder 302 drives the rotating rod 301 to rotate, causing the upper cover 2 to flip over, making it convenient for the staff to open and use the upper cover 2. After unfolding, the fixing plate 303 is released. The rebound force of the compression spring 5 pushes the fixing plate 303 to move. The fixing plate 303 supports the upper cover 2 to prevent it from loosening.
