Simultaneously, the stop belt and the traction belt are pulled, so that the cutter protecting device and the cutter can be pulled, and the cutter can be rotated out. The pulling belt is pulled continuously to drive the cutter to move so as to remove the medicine package.
Further, one end of the cutter protection device is connected with a redundant connecting belt, and the other end of the redundant connecting belt is fixedly connected with the medicine package. The traction belt is pulled to break the medicine package, and the redundant connecting belt is pulled at the same time, so that the whole medicine package can be pulled out completely.

Detailed Description
The following description of the embodiments of the present utility model is provided to facilitate understanding of the present utility model by those skilled in the art, but it should be understood that the present utility model is not limited to the scope of the embodiments, and all the utility models which make use of the inventive concept are protected by the spirit and scope of the present utility model as defined and defined in the appended claims to those skilled in the art.
As shown in fig. 1 and 2, the intrinsically safe coal mine allowable stemming of the scheme comprises an outer package 2, wherein stemming 1 is arranged in the outer package, a flame arrester medicine package 3 is arranged at one end in the outer package 2, and a medicine package 31 is arranged outside the flame arrester medicine package 3. The flame arrester package 3 may be isolated from the stemming 1 during storage and transport, and the package 31 removed prior to use. The material of the pack 31 is preferably plastic. And a package removing device is arranged between the flame arrester medicine bag 3 and the inner wall of the outer package 2.
As shown in fig. 3, the package removing device comprises a cutter 43, a cutter protecting device 44 is sleeved outside the cutter 43, and the cutter 43 is rotatably connected with the cutter protecting device 44. The knife guard 44 corresponds to the protective sheath of the knife 43 and prevents the knife 43 from being sharpened during storage or transport to scratch the flame retardant package 3 or the outer package 2 and allow the flame retardant package 3 to leak.
Specifically, the package removing device further comprises a stop belt 41 and a traction belt 42, wherein the stop belt 41 is connected with a cutter protecting device 44, and the traction belt 42 is connected with a cutter 43; the stop belt 41 and the traction belt 42 extend out of the outer package 2, so that the outer package is convenient to pull by a person, and the package removing work can be realized without damaging the outer package.
In practice, the cutter protecting device 44 and the cutter 43 can be pulled by simultaneously pulling the stop belt 41 and the pulling belt 42, so that the cutter 43 rotates out of the cutter protecting device 44. Wherein the stopping belt 41, the pulling belt 42, the cutter 43 and the cutter protecting device 44 are all contacted with the medicine package 31, the cutter 43 rotates out of the cutter protecting device 44, and then the cutting edge faces the medicine package 31, and the pulling belt 42 can be pulled continuously to drive the cutter 43 to move along the outer surface of the medicine package 31, and the cutting edge of the cutter 43 clings to the medicine package 31 and cuts the medicine package. The material strength of the outer package 2 is greater than that of the package 31, the package 31 is preferably a plastic package material that is easy to scratch, and the outer package is preferably a plastic package material that is not easy to scratch, such as PVC.
