The first embodiment is as follows:

as shown in figures 1 and 2, an anti-impact buffering device for coal mine belt transportation comprises a buffering device 2 arranged between conveying belts 1 which are high and low on two sides, wherein the buffering device 2 comprises a buffering belt 3, a bracket 4 arranged at two ends of the buffering belt 3 and positioned at two sides, a winding mechanism 5 arranged at one end of the buffering belt 3 and a baffle 6 arranged at the edge of the length direction of two sides of the buffering belt 3.

As shown in fig. 1 and 3, the vertical rod of the support 4 comprises a telescopic rod 4.1 and a fixed rod 4.2 positioned at the upper end of the telescopic rod 4.1. The height of the supports 4 at the two ends of the buffer belt 3 can be adjusted, and the buffer belt can adapt to different height drops between different high-level and low-level conveyor belts 1.

The outer surface of the fixed rod 4.2 is provided with a fixed lug 11, and two ends of the baffle 6 are rotatably connected with a bolt 13 inserted into the fixed lug 11 through a ball movable joint 12. The both ends of baffle 6 are fixed between both ends support 4 through bolt 13, and the bolt 13 of rotatable setting can rotate according to the in service behavior of the different inclination of buffer 2 and adjust the back and insert in fixed ear 11.

In this embodiment, a telescopic adjusting section 14 is provided in the middle of the baffle 6. The adjusting section 14 can be made of elastic material, rubber band, spring or telescopic rod, mainly to adapt to the length change of the buffer strip 3.

In this embodiment, as shown in fig. 1 and 4, the winding mechanism 5 includes a winding drum 7 disposed at one end of the buffer strip 3, and two ends of a central shaft of the winding drum 7 respectively penetrate through the brackets 4 at two sides and are externally connected with a handle 8. Plunger pins 9 are arranged at two ends of the central shaft, and positioning holes 10 are uniformly distributed on the inner wall of a contact hole between the support 4 and the central shaft.
