The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that any of the embodiments described herein can be incorporated into other embodiments.

[0033] Referring to Figures 1 to 6 The precise hole filling mechanism for the mine explosive truck comprises an insertion pipe 1, a filling pipe 2 and an extension mechanism 3.

[0034] The insertion pipe 1 is fixedly connected with a pair of supports 101 on the side wall, and the height of the support 101 is greater than the length of the insertion pipe 1. The support 101 can play a supporting role so that the insertion pipe 1 can be stably placed on the upper side of the blast hole.

[0035] In addition, an anchor rod 102 is connected to the support 101, and the insertion pipe 1 can be fixed at the blast hole port through the cooperation of the support 101 and the anchor rod 102, so as to fill the explosive into the blast hole.

[0036] Specifically, a pair of stable buckles 103 are connected to the side wall of the insertion pipe 1, and a pair of screw rods 303 pass through the pair of stable buckles 103 respectively, and the stable buckle 103 plays a role in stabilizing the screw rod 303.

[0037] Referring to Figures 1 to 6 The filling pipe 2 is connected to the side wall of the insertion pipe 1, and the filling pipe 2 is used to connect a filling cover 201.

[0038] The filling pipe 2 is an elastic telescopic pipe, so that the direction of the filling cover 201 can be adjusted at will, so that the filling cover 201 can adapt to the angle of the charging hose, and then the charging hose can be inserted into the filling cover 201, without the need to frequently adjust the slewing bearing and each telescopic drive to adapt the charging hose to the blast hole, which not only can ensure the filling effect of the explosive, but also can improve the filling efficiency.

[0039] In addition, the filling pipe 2 is connected with the filling cover 201, and the filling cover 201 is connected in communication with the inside of the insertion pipe 1 through the filling pipe 2. The charging hose can be inserted into the filling cover 201, and the explosive can enter the insertion pipe 1 through the filling cover 201 and the filling pipe 2, and then be filled into the blast hole through the insertion pipe 1 and the telescopic pipe 301.

[0040] Preferably, the opening diameter of the filling cover 201 is greater than the diameter of the filling pipe 2, which facilitates the insertion of the charging hose, so as to fill the explosive into the blast hole.

[0041] Referring to Figures 1 to 6The telescopic mechanism 3 is connected to the insertion tube 1, and the telescopic mechanism 3 can extend the overall length of the insertion tube 1, so that the explosive is not easy to contact the mouth wall and the side wall of the blast hole when filling the blast hole, thereby reducing the impact of the explosive on the rock blocks of the blast hole mouth wall and the side wall, so that the rock blocks and debris of the blast hole side wall are not easy to fall off, thereby improving the charging quality.

[0042] The telescopic mechanism 3 includes a telescopic pipe 301 connected to the lower bottom of the insertion tube 1 and communicating with the inside of the insertion tube 1. Through the telescopic pipe 301, the overall length of the insertion tube 1 can be extended, so that the explosive directly penetrates into the blast hole through the telescopic pipe 301, and is not easy to contact the mouth wall and the side wall of the blast hole, thereby reducing the impact of the explosive on the rock blocks of the blast hole mouth wall and the side wall, so that the rock blocks and debris of the blast hole side wall are not easy to fall off, thereby improving the charging quality.

[0043] In addition, the telescopic pipe 301 is connected with a bottom ring 302 at the end away from the insertion tube 1, and the outer diameter of the bottom ring 302 is greater than the outer diameter of the insertion tube 1, so as to facilitate the connection of a screw rod 303.

[0044] Specifically, a pair of screw rods 303 are threadedly connected to the bottom ring 302, and the rotation of the screw rods 303 can control the movement of the bottom ring 302, thereby controlling the telescopic pipe 301 to extend or retract, so that the telescopic pipe 301 can penetrate into the blast hole, and the explosive can directly extend into the blast hole through the telescopic pipe 301, thereby ensuring the explosive filling effect.

[0045] Preferably, the length of the screw rod 303 is greater than the length of the insertion tube 1 and the telescopic pipe 301, so that the telescopic pipe 301 can be extended, and the telescopic pipe 301 can penetrate into the blast hole, thereby facilitating the filling of the explosive into the blast hole.

[0046] In addition, one end of the screw rod 303 is connected with a limiting ring, and the limiting ring is arranged on the lower side of the bottom ring 302, so that the screw rod 303 is not easy to be separated from the bottom ring 302.

[0047] Please refer to Figures 1 to 6 The end of the screw rod 303 away from the bottom ring 302 penetrates through the support 101, and a belt pulley 304 is connected to the side wall of one end of the screw rod 303, and the belt pulley 304 is arranged on the upper side of the support 101. A pair of belt pulleys 304 are connected with a belt 305. When one of the screw rods 303 rotates, the rotating screw rod 303 can drive the other screw rod 303 to rotate through the cooperation of the belt pulley 304 and the belt 305, so as to control the movement of the bottom ring 302, thereby enabling the telescopic pipe 301 to extend or retract.

[0048] One end of one of the screw rods 303 is connected with a rotating disc 306, and the rotating disc 306 is arranged on the upper side of the belt pulley 304. The rotating disc 306 is rotated, and then the belt pulley 304 and the belt 305 are used to control the rotation of the pair of screw rods 303, so that the movement of the bottom ring 302 is controlled, and the telescopic pipe 301 can be telescoped to meet the filling requirement of the explosive.

[0049] In use, the insertion pipe 1 is placed above the blast hole through the support 101, and the pair of screw rods 303 is inserted into the blast hole. The support 101 and the insertion pipe 1 are fixed as a whole through the anchor rod 102.

[0050] The rotating disc 306 is rotated in the forward direction, and the rotating disc 306 rotates one of the screw rods 303. The rotating screw rod 303 drives the other screw rod 303 to rotate through the cooperation of the belt pulley 304 and the belt 305. Since the bottom ring 302 is threadedly connected with the screw rod 303, when the screw rod 303 is rotated in the forward direction, the bottom ring 302 is moved downward due to the thread action, so that the telescopic pipe 301 is elongated, and the telescopic pipe 301 is deepened into the blast hole.

[0051] Since the filling pipe 2 is an elastic telescopic pipe, the direction of the filling cover 201 can be adjusted at will, so that the filling cover 201 can adapt to the angle of the charging hose, and the charging hose can be inserted into the filling cover 201, and the charging hose does not need to be frequently adjusted to adapt to the blast hole through the slewing bearing and the telescopic driving members. The filling effect of the explosive is ensured, and the filling efficiency is improved.

[0052] The explosive in the charging hose enters the insertion pipe 1 through the filling cover 201 and the filling pipe 2, and then is directly filled into the blast hole through the telescopic pipe 301. Since the telescopic pipe 301 is arranged, the explosive is not easy to contact the mouth wall and the side wall of the blast hole during the filling of the explosive, so that the impact of the explosive on the rock blocks of the mouth wall and the side wall of the blast hole is reduced, the rock blocks and rock debris of the side wall of the blast hole are not easy to fall, and the charging quality is improved.

[0053] When the explosive is filled, the rotating disc 306 is rotated in the reverse direction, the bottom ring 302 is moved upward, the telescopic pipe 301 is retracted, the anchor rod 102 is removed, and then the insertion pipe 1 and the support 101 are removed from the blast hole.

[0054] The above description is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion in the utility model specification and the drawings, or direct or indirect application in other related technical fields is also included in the patent protection range of the utility model.
