In the practical use process of the invention, especially when horizontal punching is carried out, the explosive is filled by adopting external force to press the explosive to the position near the explosive outlet 22 of the rotating shaft 2, but the explosive belongs to a flammable and explosive piece, and can not be excessively extruded except fire prevention and water prevention, otherwise the explosive can be out of work or even explode, and safety accidents occur. Therefore, as shown in fig. 3 and 6, the rotating shaft 2 of the present invention is fixedly installed in the casing 61, the casing 61 rotates along with the rotating shaft 2 during drilling, and the sliding bar 63 is slidably installed on the shaft body of the rotating shaft 2. As shown in fig. 4 and 6, after drilling is finished, the driving mechanism 67 fixedly mounted on the mounting base 1 moves the low driving ring 69 to the end close to the medicine outlet 22 of the rotating shaft 2, the low driving ring 69 pushes the sliding bar 63 to move on the shaft body of the rotating shaft 2 to drive the expansion ring 66 hinged on the sliding bar 63 to the notch 62 on the casing 61, and then the sliding bar 63 continues to move, because the expansion ring 66 is clamped at the notch 62, at this time the connecting rod 65 rotates to eject the expansion ring 66 out of the notch 62 of the casing 61 to the inner wall of the drilling; similarly, after the low driving ring 69 is moved, the driving mechanism 67 drives the high driving ring 68 to move, so as to eject the expansion piece on the sliding bar 63 out of the notch 62 of the casing 61, at this time, the expansion ring 66 and the casing 61 seal the drilled hole, and at this time, the medicine outlet 22 on the drill 5 and the rotating shaft 2 is in an open state. In the present embodiment, as shown in fig. 4, 5, and 6, since the sliding bar 63 moves toward the medicine outlet 22 on the rotating shaft 2, the sliding column 53 located at the medicine outlet 22 on the rotating shaft 2 is pushed by the sliding bar 63 to jack up the sector 51, and the sliding column 53 slides in the second sliding groove 52 on the sector 51 while jacking up the sector 51. Since the sector 51 is rotatably mounted on the end of the discharge port 22 of the rotary shaft 2, when the sector 51 is pushed up, the sector 51 opens the discharge port 22, allowing explosive to leave the rotary shaft 2. The mounting 1 then carries the shaft 2 and the drill bit 5 to begin to retract away from the borehole. As shown in fig. 3, because the expansion ring 66 and the casing 61 seal the borehole, as the mounting seat 1 is withdrawn, the expansion ring 66 and the casing 61 are withdrawn to form negative pressure in the borehole, so that the explosive at the explosive inlet 21 of the rotating shaft 2 is pressed into the explosive outlet 22 of the rotating shaft 2 by air under the action of the external air pressure; as the shaft 2 and bit 5 exit the borehole, the explosive charge will leave the shaft 2 and remain at the root of the borehole, completing the charge. According to the explosive-filling device, the drill bit 5 is opened after drilling is finished, the recovery action that the drill bit 5 leaves the drill hole is utilized, negative pressure is formed in the drill hole, explosive in the hollow rotating shaft 2 is sucked into the drill hole, the explosive is prevented from being damaged due to rigid extrusion and friction of the hole wall in the explosive-filling process, manual operation is avoided, the explosive is protected, the economic cost and the time cost for filling the explosive in the drill hole are saved, and the production efficiency is improved.
As shown in fig. 6, the high-position drive ring 68 and the low-position drive ring 69 are provided in the present invention, because when the expansion ring 66 contracts from the notch 62, the expansion ring 66 contracts in the radial direction of the rotating shaft 2, so that the two groups of expansion rings 66 originally formed into a ring shape cannot be located at the same height of the rotating shaft 2, otherwise, they interfere with each other, and the heights of the two groups of expansion rings 66 are optionally staggered from each other in the present invention, so as to avoid interference.
In order to ensure that air pressure can push the explosive to the explosive outlet 22 of the rotating shaft 2, a gasket can be placed on the explosive when the explosive is filled, the size of the end face of the gasket is consistent with the cross-sectional area of the hollow channel of the rotating shaft 2, and the gasket is slidably arranged in the hollow channel of the rotating shaft 2. Thus, when the rotating shaft 2 and the drill bit 5 leave the drill hole, outside air cannot pass through the explosive and the hollow channel of the rotating shaft 2, and the thrust of air pressure on the explosive is ensured; meanwhile, the gasket can prevent external sundries from falling into the drill hole after the explosive filling is finished, so that the explosive is protected, and the blasting effect is ensured.

When the expansion ring is pulled by withdrawing the rotating shaft and the drill bit, the expansion ring made of rubber can seal a drill hole, so that the drill hole forms negative pressure to suck explosives, and can clean the drill hole, and the residual expansion ring in the drill hole is used as a further scheme of the invention, the drill bit 5 comprises a fan-shaped part 51 which is rotatably arranged at one end of the rotating shaft 2 close to the explosive outlet 22, the fan-shaped part 51 is annularly arranged along the circumferential direction of the rotating shaft 2, a second sliding groove 52 is formed in one side surface of the fan-shaped part 51 close to the axis of the rotating shaft 2, a sliding column 53 is fixedly arranged at one end of the sliding strip 63 close to the explosive outlet 22, and the sliding column 53 is slidably arranged in the second sliding groove 52; when the sliding bar 63 slides to the side close to the medicine outlet 22 of the rotating shaft 2, the drill 5 is in a1 state; when the slide bar 63 slides away from the medicine outlet 22 of the rotary shaft 2, the drill 5 is in a state of a 2.
When the medicine filling machine is used for drilling, the drill bit 5 is in a closed state to close the medicine outlet 22 on the rotating shaft 2, and when medicine is filled, the drill bit 5 is in an open state to open the medicine outlet 22 on the rotating shaft 2. As shown in fig. 4, 5 and 6, the drill 5 is closed during drilling to close the medicine outlet 22 on the rotating shaft 2. After drilling, since the driving mechanism 67 drives the sliding bar 63 to move toward the drug outlet 22 on the rotating shaft 2, the sliding column 53 at the drug outlet 22 of the rotating shaft 2 is pushed by the sliding bar 63 to jack up the sector 51, and the sliding column 53 slides in the second sliding groove 52 of the sector 51 while jacking up the sector 51. Since the sector 51 is rotatably mounted on the end of the discharge port 22 of the rotary shaft 2, when the sector 51 is pushed up, the sector 51 opens the discharge port 22, allowing explosive to leave the rotary shaft 2. The invention utilizes the driving mechanism 67 to drive the sliding bar 63 to move on the rotating shaft 2, thereby not only driving the expansion ring 66 to eject from the gap 62 of the casing 61, but also sealing the drilled hole; the sliding column 53 is also driven to slide in the second sliding groove 52 of the sector 51, the sector 51 is jacked up, the drill 5 is opened, and the medicine outlet 22 on the rotating shaft 2 is opened.
