[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] like Figure 1-7 As shown:

[0037] The blocking piece 100 and the pull wire 8 are consumables and can be replaced. The winding device 3 is installed in the wire box 11. The pull wire 8 is wound on the outer wall of the ring. The inner diameter structure of the ring is adapted to the rotating shaft of the winding device 3, so that the ring can be detachably sleeved on the outer wall of the rotating shaft of the winding device 3. The winding device 3 drives the ring to rotate forward and reverse, thereby realizing the winding or release of the pull wire 8. The outer wall of the pull wire 8 is provided with one-way limit members 81 at equal intervals along its length. The one-way limit member 81 is a rotating body structure with one end larger and the other end smaller. Figure 6 As shown, the small end of the one-way limit member 81 is relatively forward;

[0038] like Figure 1 As shown, the hollow cylinder 1 extends straight from the left wall to the right to form an inner cavity. The inner cavity of the hollow cylinder 1 is divided into a filling area and a raw material area from left to right. The filling area is located on the side close to the opening of the inner cavity of the hollow cylinder 1 relative to the raw material area; Figure 2 As shown, a number of evenly distributed elastic limiters 13 are provided at the junction between the loading area and the raw material area. A first elastic member 7 is installed in the raw material area. When a row of blocking pieces 100 are placed in the raw material area, the elastic force of the first elastic member 7 on the right side causes the leftmost blocking piece 100 in the row of blocking pieces 100 to abut against the elastic limiters 13. Due to the restriction of the elastic limiters 13, the initial limit of the blocking piece 100 moving to the left is achieved. A through hole 101 is opened in the middle of the blocking piece 100, as shown in FIG. Figure 6 As shown, the through hole 101 is a rotating body structure with one end being larger and the other end being smaller, and the smaller end of the through hole 101 is relatively located close to the inner opening of the hollow cylinder 1 .

[0039] like Figure 1 As shown, a gun mud box 2 is installed on the outside of the hollow cylinder 1, the output end of the gun mud box 2 extends to the filling area, and an electric control valve or a metering pump is installed at the output end of the gun mud box 2, and the gun mud in the gun mud box 2 is quantitatively transported to the filling area through the electric control valve or the metering pump.

[0040] The hollow cylinder 1 is provided with a transverse movement device 5 and a sheet moving mechanism 4. The transverse movement device 5 can adopt a screw drive structure or a linear movement module. The transverse movement device 5 drives the mounting seat 41 to move in the same direction as the arrangement direction of a row of blocking sheets 100. A slip ring 42 is fixedly installed on the mounting seat 41. Figure 3 As shown, the sheet moving mechanism 4 has two groups symmetrically installed on both sides of the slip ring 42. The two groups of sheet moving mechanisms 4 are relatively located on the front and back sides of the upper part of the inner cavity of the hollow cylinder 1. The sheet moving mechanism 4 includes a first one-way pull rod 43, a fixing seat 44, a second elastic member 45 and a second one-way pull rod 46. Figure 4As shown, the first one-way pull rod 43 is fixed to the fixed seat 44, and the second one-way pull rod 46 is slidably connected to the fixed seat 44 along its length direction. The second one-way pull rod 46 and the fixed seat 44 are both provided with a first magnetic member (not shown in the figure). The second one-way pull rod 46 and the fixed seat 44 are magnetically repelled by two sets of first magnetic members of the same polarity. A second elastic member 45 is connected between the slip ring 42 and the fixed seat 44. The second elastic member 45 can be a tension spring. The elastic force of the second elastic member 45 drives the fixed seat 44 to approach the slip ring 42 under normal conditions. The free ends of the first one-way pull rod 43 and the second one-way pull rod 46 both pass through the slip ring 42 in the same direction and extend to the inner cavity of the hollow cylinder 1. The free ends of the first one-way pull rod 43 and the second one-way pull rod 46 are designed to have an inclined chamfered structure near the side of a row of blocking plates 100.

[0041] A slide groove is provided on the upper part of the inner wall of the inner cavity of the hollow cylinder 1, and the first one-way pull rod 43 and the second one-way pull rod 46 slide linearly relative to each other in the slide groove. The free ends of the first one-way pull rod 43 and the second one-way pull rod 46 are inserted into the inner cavity of the hollow cylinder 1 through the slide groove. Since the slide groove is relatively located at the upper part of the inner cavity of the hollow cylinder 1, the gun mud in the filling area can be prevented from entering the slide groove; further, a folding protective cover is connected between the left inner wall of the slide groove and the first one-way pull rod 43, the right inner wall of the slide groove and the second one-way pull rod 46, and the folding protective cover is used to prevent the gun mud in the inner cavity of the hollow cylinder 1 from being squeezed out through the slide groove.

[0042] like Figure 1 As shown, the hollow cylinder 1 is provided with a second magnetic member 9 near its opening position. The second magnetic member 9 and the first magnetic member 6 are magnetically attracted to each other, and the attractive magnetic force between the second magnetic member 9 and the first magnetic member 6 is greater than the repulsive magnetic force between the two groups of first magnetic members 6.

[0043] like Figure 1 As shown, a shearing mechanism 6 is installed near the opening of the hollow cylinder 1. The shearing mechanism 6 can adopt a scissor-type structure, or a telescopic device and a blade installed at the output end of the telescopic device. Under normal circumstances, the telescopic device is shortened so that the blade leaves the loading area; the telescopic device is extended to drive the blade to move and cut the pull wire 8.

[0044] Working principle:

[0045] like Figure 1 As shown, under normal conditions, the leftmost sealing piece 100 (marked as a) in the hollow cylinder 1 is relatively close to the opening position of the hollow cylinder 1. Then, the cannon mud in the cannon mud box 2 is quantitatively transported to the filling area through the electric control valve or the quantitative pump, and the transverse movement device 5 drives the moving mechanism 4 to move rightward to the right limit position, as shown in FIG. Figure 7As shown, from left to right, the second group of blocking pieces 100 (marked as b) is now in contact with the elastic limiting member 13. At this time, the free end of the first one-way pull rod 43 is located between the second group of blocking pieces 100 (marked as b) and the third group of blocking pieces 100 (marked as c), and the free end of the second one-way pull rod 46 is located between the third group of blocking pieces 100 (marked as c) and the fourth group of blocking pieces 100.

[0046] Afterwards, the transverse movement device 5 drives the second group of blocking pieces 100 (marked as b) and the third group of blocking pieces 100 (marked as c) to move leftward to the left limit position through the sheet moving mechanism 4. During this process, the second group of blocking pieces 100 (marked as b) and the third group of blocking pieces 100 (marked as c) are pushed by external force to cross the elastic limit member 13, and the remaining row of blocking pieces 100 are still abutted and limited by the elastic limit member 13 under the push of the first elastic member 7; at the same time, the second group of blocking pieces 100 (marked as b) and the third group of blocking pieces 100 (marked as c) push the gun mud in the filling area, and the first group of blocking pieces 100 (marked as a) follow and move leftward into the blasting hole 200;

[0047] During the leftward movement of the second one-way pull rod 46 in the sheet moving mechanism 4, it passes through the second magnetic member 9. Due to the magnetic attraction between the second magnetic member 9 and the first magnetic member, the second one-way pull rod 46 is relatively close to the fixed seat 44, so that the free end of the second one-way pull rod 46 is relatively separated from the third group of blocking pieces 100 (marked as c). At this time, the third group of blocking pieces 100 (marked as c) loses the thrust and stays in place, while the second group of blocking pieces 100 (marked as b) is still abutted by the first one-way pull rod 43 and continues to be pushed forward for a distance; so that a distance is generated between the second group of blocking pieces 100 (marked as b) and the third group of blocking pieces 100 (marked as c), and this distance also includes a one-way limit member 81; during this process, the winding device 3 is in a loosened state, so that the pull wire 8 can be stretched following the release; the state at this time is as follows Figure 5 As shown;

[0048] Afterwards, the winding device 3 rotates to wind the pull wire 8 around its outer wall. At this time, the leftmost sealing piece 100 (marked as a) is driven to move to the right by the one-way limit piece 81 and the pull wire 8 on its left side, so that the leftmost sealing piece 100 (marked as a) is close to the relatively fixed second group of sealing pieces 100 (marked as b), thereby compacting the gun mud 300 therebetween, thereby realizing that the gun mud 300 is compacted and filled in the opening position of the blasting hole 200 without external support.

[0049] Afterwards, the pull wire 8 between the second group of blocking pieces 100 (marked as b) and the third group of blocking pieces 100 (marked as c) can be manually cut, and the one-way limit piece 81 is retained on the left side of the third group of blocking pieces 100 (marked as c); or it can be automatically cut off by the shearing mechanism 6.

[0050] After that, the next process is continued. The gun mud is quantitatively transported to the loading area, and the transverse movement device 5 drives the sheet moving mechanism 4 to move rightward and reset. During this process, due to the mutual magnetic force between the second magnetic member 9 and the first magnetic member 6, the free end of the second one-way pull rod 46 is relatively far away from the third group of blocking pieces 100 (marked as c). The third group of blocking pieces 100 (marked as c) will not affect the rightward movement of the second one-way pull rod 46; and during the rightward movement of the first one-way pull rod 43, since the right side of the third group of blocking pieces 100 (marked as c) is restricted by the gun mud, the free end of the first one-way pull rod 43 can pass over the third group of blocking pieces 100 (marked as c) with the cooperation of the inclined chamfer and the second elastic member 45;

[0051] During this process, the right side of the original third group of blocking pieces 100 (marked as c) is limited by the taphole mud and becomes the leftmost blocking piece 100 (marked as a) of the next process.

[0052] like Figure 7 This is a schematic diagram of the state when the transverse moving device 5 drives the sheet moving mechanism 4 to move to the right to the right limit. The free ends of the first one-way pull rod 43 and the second one-way pull rod 46 can unidirectionally cross the blocking piece 100 through the inclined chamfer on the right side and the second elastic member 45; at this time, the second one-way pull rod 46 is away from the second magnetic member 9, and under the repulsive force of the two groups of first magnetic members, the second one-way pull rod 46 is relatively away from the fixed seat 44.

[0053] like Figure 1 and 6 As shown, the arrow indicates the unidirectional penetration direction of the pull wire 8 relative to the blocking piece 100 in the raw material area. Since the blocking pieces 100 in the raw material area are closely arranged, during the advancement of the pull wire 8, the small end of the one-way limiting member 81 first cooperates with the large end of the through hole 101 to achieve insertion, thereby achieving unidirectional crossing of the through hole 101; during this process, a row of blocking pieces 100 in the raw material area are still abutted and limited by a number of elastic limiting members 13 and cannot be crossed; the one-way limiting member 81 can be made of elastic material.
