[0019] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the utility model will be briefly introduced below in conjunction with the drawings and embodiments.

[0020] Embodiment 1

[0021] like Figure 1-Figure 4 As shown, a material blockage and broken pin detection device for a raw coal double-toothed roller crusher comprises a box body 1, a crushing roller shaft 2 is arranged inside the box body 1, a crushing roller 3 is fixedly connected to the outer wall of the crushing roller shaft 2, sliding systems 4 are fixedly connected to the outer walls on both sides of the box body 1, the sliding systems 4 on both sides of the box body 1 are fixedly connected to both ends of a C-shaped connecting rod 5, an outer wall on one side of the box body 1 is fixedly connected to an electric push rod 6, and the other end of the electric push rod 6 is fixedly connected to the C-shaped connecting rod 5.

[0022] It should be noted that the sliding system includes a limit box 401, which is fixedly connected to the outer walls on both sides of the box body 1, a connecting sleeve 402, which is sleeved on the outer wall of the crushing roller shaft 2, and a connecting rod 403, one end of which passes through the outer wall of one side of the limit box 401 and is fixedly connected to one end of the C-shaped connecting rod 5, and the other end is fixedly connected to the connecting sleeve 402.

[0023] It should be noted that notches 7 are respectively provided on the outer walls of both sides of the box body 1 .

[0024] It should be noted that the crushing roller shaft 2 passes through the outer walls on both sides of the box body 1.

[0025] In the embodiment, when the crusher is blocked or the pin is broken, the staff stops the equipment in time and starts the electric push rod 6. The electric push rod 6 drives the C-shaped connecting rod 5 to slide, and the C-shaped connecting rod 5 drives the connecting rod 403 to slide at the upper limit of the limit box 401. The connecting rod 403 drives the connecting sleeve 402 to slide forward, and the connecting sleeve 402 drives the crushing roller shaft 2 to slide forward. The crushing roller shaft 2 drives the crushing roller 3 to slide forward. At this time, the gap between the two crushing rollers 3 is increased, which is convenient for the staff to overhaul and reduce the occurrence of safety accidents.

[0026] Embodiment 2
