As a further aspect of the present invention, the expansion assembly includes a sliding bar 63, first sliding grooves 64 are spaced apart on the circumferential surface of the rotation shaft 2, the first sliding grooves 64 are disposed along the axial length direction of the rotation shaft 2, and the sliding bar 63 is slidably installed in the first sliding grooves 64; an expansion ring 66 is hinged on the sliding strip 63 through a connecting rod 65, one end of the connecting rod 65 is hinged on the sliding strip 63, the other end of the connecting rod is hinged on the expansion ring 66, and the expansion ring 66 is slidably arranged in the casing 61; one end of the sliding strip 63, which is close to the medicine inlet 21, is fixedly connected with a driving ring, and the driving ring is connected with a driving mechanism 67 fixedly arranged on the mounting seat 1; the driving ring comprises a high-position driving ring 68 and a low-position driving ring 69, the high-position driving ring 68 is closer to the medicine inlet 21 than the low-position driving ring 69, the sliding strips 63 connected with the high-position driving ring 68 are arranged at intervals with the driving ring connected with the low-position driving ring 69, and when the sliding strips 63 slide to the side close to the medicine outlet 22 of the rotating shaft 2, the expansion piece extends out of the notch 62 to seal the drilling hole.
As a further aspect of the invention, the expansion ring 66 is made of rubber.
In the practical use process, particularly in the horizontal punching process, the explosive filling needs to be pressed to the vicinity of the explosive outlet 22 of the rotating shaft 2 by adopting external force, but the explosive belongs to inflammable and explosive components, and can not be excessively extruded except fireproof and waterproof components, otherwise, the explosive can be invalid or even exploded, and safety accidents can occur. Therefore, as shown in fig. 3 and 6, the rotary shaft 2 of the present invention is fixedly installed in the casing 61, the casing 61 rotates together with the rotary shaft 2 during drilling, and the sliding bar 63 is also slidably installed on the shaft body of the rotary shaft 2. As shown in fig. 4 and 6, after the drilling is finished, the driving mechanism 67 fixedly installed on the mounting seat 1 drives the low-level driving ring 69 to move towards one end close to the medicine outlet 22 of the rotating shaft 2, the low-level driving ring 69 pushes the sliding strip 63 to move on the shaft body of the rotating shaft 2 to drive the expansion ring 66 hinged on the sliding strip 63 to the notch 62 on the casing 61, then the sliding strip 63 continues to move, and the expansion ring 66 is clamped at the notch 62, so that the connecting rod 65 rotates to eject the expansion ring 66 from the notch 62 of the casing 61 to the inner wall of the drilling at the moment; similarly, after the low-level driving ring 69 is moved, the driving mechanism 67 drives the high-level driving ring 68 to move, the expansion piece on the sliding strip 63 is ejected out of the notch 62 of the casing 61, at this time, the expansion ring 66 seals the drilled hole with the casing 61, at this time, the drill bit 5 and the medicine outlet 22 on the rotating shaft 2 are in an open state. The present embodiment provides a way to open the drill 5 and the medicine outlet 22, as shown in fig. 4, 5 and 6, because the sliding bar 63 moves to the medicine outlet 22 side on the rotating shaft 2, the sliding column 53 at the medicine outlet 22 of the rotating shaft 2 is pushed by the sliding bar 63 to lift the sector 51, and the sliding column 53 slides in the second sliding groove 52 on the sector 51 while lifting the sector 51. Because the sector 51 is rotatably mounted at one end of the discharge opening 22 of the rotary shaft 2, when the sector 51 is lifted up, the sector 51 opens the discharge opening 22, allowing the explosive to leave the rotary shaft 2. The mounting 1 then drives the rotary shaft 2 and the drill bit 5 to begin to withdraw from the borehole. As shown in fig. 3, because the expansion ring 66 and the casing 61 seal the bore hole at this time, as the mounting seat 1 is retracted, the expansion ring 66 and the casing 61 are retracted to form a negative pressure in the bore hole, so that the explosive located at the explosive inlet 21 of the rotary shaft 2 is pressed into the explosive outlet 22 end of the rotary shaft 2 by air under the action of external air pressure; as the rotary shaft 2 and the drill bit 5 leave the borehole, the explosive can leave the root of the borehole after leaving the rotary shaft 2, and the explosive filling is completed. According to the invention, the drill bit 5 is opened after the drilling is completed, and the recovery action of the drill bit 5 leaving the drilling is utilized, so that negative pressure is formed in the drilling, and the explosive in the hollow rotating shaft 2 is sucked into the drilling, so that the damage of the explosive caused by rigid extrusion and friction of the hole wall in the charging process is avoided, the manual operation is avoided, the explosive is protected, the economic cost and the time cost of filling the drilling are saved, and the production efficiency is improved.
As shown in FIG. 6, the high-level driving ring 68 and the low-level driving ring 69 are arranged in the invention, because when the expansion ring 66 is contracted from the notch 62, the radial direction of the expansion ring 66 is contracted in the rotating shaft 2, so that the two groups of expansion rings 66 which are originally formed into a ring shape cannot be positioned at the same height of the rotating shaft 2, otherwise, the two groups of expansion rings interfere with each other, and the heights of the two groups of expansion rings 66 are staggered with each other at will, so that the interference is avoided.
In order to ensure that the air pressure can push the explosive to the explosive outlet 22 of the rotating shaft 2, a gasket can be placed on the explosive to fill the explosive, the end face of the gasket has a size consistent with the cross section area of the hollow passage of the rotating shaft 2, and the gasket is slidably arranged in the hollow passage of the rotating shaft 2. When the rotating shaft 2 and the drill bit 5 leave the drill hole, external air cannot pass through the explosive and the hollow channel of the rotating shaft 2, so that the thrust of air pressure to the explosive is ensured; meanwhile, the gasket can prevent external sundries from falling into a drilled hole after filling, so as to protect explosive and ensure blasting effect.
It is noted that the expansion ring of the present invention is made of rubber. When the rotating shaft and the drill bit are retracted to pull the expansion ring, the expansion ring made of rubber can seal the drilling hole, so that the drilling hole forms negative pressure to suck explosive, the drilling hole can be cleaned, the drill bit 5 is remained in the drilling hole when the drilling hole is drilled as a further scheme of the invention, the drill bit 5 comprises a sector part 51 rotatably arranged at one end of the rotating shaft 2 close to the medicine outlet 22, the sector 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 sector 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 medicine 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 bit 5 is in a1 state; when the slide bar 63 slides to the side away from the medicine outlet 22 of the rotation shaft 2, the drill bit 5 is in the state a 2.
In the invention, the drill bit 5 is in a closed state when drilling, the medicine outlet 22 on the rotating shaft 2 is closed, and the drill bit 5 is in an open state when filling medicine, and the medicine outlet 22 on the rotating shaft 2 is opened. As shown in fig. 4, 5 and 6, the drill bit 5 is in a closed state during drilling, and the medicine outlet 22 on the rotating shaft 2 is closed. After the drilling is completed, the driving mechanism 67 drives the sliding bar 63 to move towards the medicine outlet 22 on the rotating shaft 2, so that the sliding column 53 at the medicine 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 on the sector 51 while jack up the sector 51. Because the sector 51 is rotatably mounted at one end of the discharge opening 22 of the rotary shaft 2, when the sector 51 is lifted up, the sector 51 opens the discharge opening 22, allowing the explosive to leave the rotary shaft 2.
