The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1:

[0021] See also Figure 1 As shown, the utility model provides a protective device for jaw crusher processing, including a jaw crusher body 1, a frame 2 is fixedly installed on the bottom of the jaw crusher body 1, a protective cover 3 is rotatably installed on the upper left end of the frame 2 through a pin shaft, an adjusting knob 4 is threadedly installed on the front of the right end of the protective cover 3, a support frame 5 is fixedly installed on the right side of the top of the jaw crusher body 1, a rubber plate 6 is fixedly installed on the bottom of the left end of the support frame 5, a support spring 7 is fixedly installed on the bottom of the rubber plate 6, and a protective baffle 8 is fixedly installed on the lower end of the support spring 7.

[0022] This technical solution sets up the use of a protective cover 3 and a protective baffle 8. The protective baffle 8 can protect and block the top of the feed port to prevent upward-flying stones from causing collision damage to equipment and personnel. At the same time, the protective cover 3 can be stuck on the top of the frame 2 and block the outside of the feed port. It can form an integrated structure with the protective baffle 8 to block and protect stones flying during processing, while ensuring the safety of the processing personnel, and also improving the processing safety. Example 2:

[0023] On the basis of embodiment 1, the present invention is as follows Figure 4 As shown, a limit spring 9 is fixedly installed on the left end of the top of the support frame 5, a limit clamping plate 10 is fixedly installed on the upper end of the limit spring 9, and a side baffle 11 is fixedly installed on the left end of the limit clamping plate 10.

[0024] Use Figure 1 In the technical solution shown, the limit spring 9 squeezes and supports the limit clamp 10. After the protective cover 3 is clamped above the feed port, the limit clamp 10 can be fitted with the inner wall of the protective cover 3 to ensure the firmness of the upper end of the protective cover 3 after installation, and the side baffle 11 connected to the left end can limit the moving direction to avoid tilting.

[0025] Secondly, in the technical solution, limit baffles 12 are fixedly installed on the front and rear sides of the protective baffle 8, and the limit baffles 12 are located on the front and rear sides of the support frame 5; a transparent glass cover 13 is fixedly installed on the bottom of the protective cover 3, and the transparent glass cover 13 is made of tempered glass.

[0026] It uses Figure 1In the technical solution shown, the limit baffle 12 can limit the front and rear ends of the protective baffle 8, and can ensure the balance when moving up and down when it is hit by flying stones. In addition, the transparent glass cover 13 made of tempered glass has a high structural strength and will not be damaged by flying stones for a long time. Example 3:

[0027] The utility model Figures 1-4 As shown, the left end of the protective baffle 8 extends to above the feed port of the jaw crusher body 1, and the vertical height of the protective cover 3 is greater than the height between the support frame 5 and the jaw crusher body 1; an anti-collision protection pad is installed on the inner side of the protective cover 3, and the anti-collision protection pad is distributed on the inner wall of the protective cover 3 throughout the range; a bottom plate is welded to the bottom of the frame 2, and a reinforcing support plate is welded at the connection between the bottom plate and the frame 2.
