[0015] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor belong to the range of protection of the utility model.

[0016] Embodiment 1

[0017] Please refer to Figure 1 、 Figure 2 and Figure 3 , a mine folding arm, including: mounting seat 1, the top wall of mounting seat 1 is hinged with support arm 2 and first driving part 3, the end of first driving part 3 away from mounting seat 1 is hinged with the side wall of support arm 2, and first driving part 3 refers to oil cylinder, which is used for driving support arm 2 to rotate and change its pitch angle through the extension and retraction of oil cylinder, the end of support arm 2 away from mounting seat 1 is hinged with first telescopic arm 4, and second driving part 5 (both ends of second driving part 5 are hinged with the fixed end of first telescopic arm 4 and support arm 2 through pin shaft) is hinged between the fixed end of first telescopic arm 4 and support arm 2, and second driving part 5 is also oil cylinder, which is used for driving first telescopic arm 4 to rotate through the extension and retraction of oil cylinder;

[0018] Please refer to Figure 1 、 Figure 2 and Figure 3The moving end of the first telescopic arm 4 is provided with a support 6, the second telescopic arm 7 and the third driving member 8 are hingedly connected to the support 6, the end of the third driving member 8 away from the support 6 is hingedly connected to the fixed end of the second telescopic arm 7, the third driving member 8 is a hydraulic cylinder, and the second telescopic arm 7 is driven to rotate by the extension and contraction of the hydraulic cylinder; the support arm 2 and the second telescopic arm 7 rotate on the opposite side of the first telescopic arm 4, the support arm 2, the first telescopic arm 4 and the second telescopic arm 7 form a zigzag shape, the directions of the support arm 2, the first telescopic arm 4 and the second telescopic arm 7 are adjusted by sections, and the rotating directions of the second telescopic arm 7 and the support arm 2 are located on the upper and lower sides of the first telescopic arm 4 respectively, so that the second telescopic arm 7 does not contact the inner wall of the inclined ore chute when entering the ore chute, the second telescopic arm 7 can be deeply inserted into the ore chute, and the folding arm can fix the explosive to the best blasting area.
