In mining work, usually adopt the mode of deep hole blasting to mine. Specifically, the blast hole is dug deep at the target first, then explosives are poured into the blast hole, and the fuse is inserted into the blast hole. After the fuse is ignited, the rock is blasted as the explosive explodes. Because in the process of digging the blasthole deeply, the bottom of the blasthole sometimes overflows from the bottom of the blasthole, which mixes with the explosives in the blasthole and reduces the power of the explosive explosion. So, someone invented the isolator, which is used to isolate groundwater and explosives.

For example, the notification number is the existing patent of CN216770369, which separates groundwater and explosives by setting isolators in the blast holes, so as to avoid groundwater from affecting the explosion of explosives.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention.

Referring to Fig. 1 , the present invention provides a delivery device 100, which is used to put into the blast hole of the mine, so as to isolate the explosive from the groundwater in the blast hole, and prevent the explosive from being wetted by the ground water to affect the blasting.

The delivery device 100 includes an isolation structure 101 and a delivery structure 102. The delivery structure 102 is detachably connected to the isolation structure 101. The delivery structure 102 can drive the isolation structure 101 into the blast hole dug in advance in the mine. When the isolation structure 101 is ready to be placed, the delivery structure 102 can be separated from the isolation structure 101, and the isolation structure 101 can be left alone in the blast hole. At this time, explosives can be placed on the top of the isolation structure 101, and the isolation structure 101 can isolate the explosives on the top from the groundwater at the bottom, so as to prevent the explosives from being wetted by the groundwater, so that the explosives can fully explode.

The isolation structure 101 includes a first elastic isolator 1, a second elastic isolator 2 and a plunger 3, wherein both ends of the plunger 3 are detachably plugged into the first elastic isolator 1 and the second elastic isolator 2, and in other embodiments, the two ends of the plunger 3 can also be connected to the first elastic isolator 1 and the second elastic isolator 2 by means of a fixed connection.

Referring to FIG. 3 , the first elastic spacer 1 includes a connected base 11 and an elastic body 12 , and the elastic body 12 is arranged around the periphery of the base 11 so that the elastic body 12 can fully abut against the wall of the blast hole when expanded.

The side of the base 11 facing away from the elastic body 12 is provided with a locking hole 111 , and the locking hole 111 is used for detachable insertion with the plunger 3 . The engaging hole 111 runs through the base 11 , so that the powdered explosive on the base 11 can be filled into the plunger 3 through the engaging hole 111 .

The base 11 is provided with a force rope 13, the two ends of the force rope 13 are connected to the base 11, and a traction hole 14 is formed between the base 11. The traction hole 14 can be used for the delivery structure 102 to connect the force rope, so as to drive the first elastic spacer 1 or the whole isolation structure 101 to be lowered in the blast hole.

The elastic body 12 is made of elastic material, such as rubber or silica gel, so that the elastic body 12 has good elastic deformation ability, and can be opened quickly when it is unbound.

The difference between the second elastic spacer 2 and the first elastic spacer 1 is that the diameter of the elastic body of the second elastic spacer 2 in the expanded state is smaller than the diameter of the elastic body 12 of the first elastic spacer 1 in the opened state, and even smaller than the diameter of the blast hole, so that during the lowering of the isolation structure 101 in the blast hole, the second elastic spacer 2 is prevented from being stuck in the blast hole and hindering the lowering of the isolation structure 101.

It should be emphasized that the diameter of the elastic body 12 of the first elastic spacer 1 is larger than the diameter of the blast hole in the expanded state, so that the elastic body 12 can be stuck on the wall of the blast hole and fixed in the expanded state.

The plunger 3 is hollow with both ends open. When the plunger 3 is plugged into the clamping hole 111 of the first elastic spacer 1, the clamping hole 111 communicates with the inside of the plunger 3. The powdered explosive located on the first elastic spacer 1 can be filled into the interior of the plunger 3 through the clamping hole 111, and then reaches the second elastic spacer 2 at the other end of the plunger 3. The explosive can pass through the second elastic spacer 2. Therefore, after the isolation structure 101 is placed in the blasthole and fixed, a part of the explosive is poured into the top of the isolation structure 101, and then another isolation structure 101 can be placed on the explosive, and the explosive can be continuously poured into the isolation structure 101 again. In addition, the inside of the plunger 3 of the isolation structure 101 is filled with explosives, and the explosives at the upper and lower ends of the isolation structure 101 are connected, which means that the isolation structure 101 can also play the role of connecting explosives, so that after the explosives at the bottom of the isolation structure 101 are detonated, the explosives at the top of the isolation structure 101 can be transmitted to detonate, thereby increasing the explosive power.

The eccentric hook 5 is used to hook the stressed rope 13 of the first elastic isolator 1 so as to pull the isolation structure 101 down in the blast hole. The limit assembly 6 is used to detachably clamp the elastic body 12 of the first elastic isolator 1 to constrain the elastic body 12, preventing the elastic body 12 from opening naturally in advance and engaging the hole wall of the blast hole, affecting the lowering of the isolation structure 101. The entire isolation structure 101 can be controlled to be gradually lowered in the blast hole by retracting and retracting the traction rope 4 through the reel 7 . When the isolation structure 101 is lowered to the target position of the blast hole, stop releasing the traction rope 4 through the reel 7. Now the reel 7 is lowered, and the eccentric hook 5 also descends thereupon, so that the eccentric hook 5 is separated from the force rope 13 of the first elastic spacer 1, and then the reel 7 is rotated, and the traction rope 4 is rewound. The traction rope 4 drives the limit assembly 6 to move upward, so that the limit assembly 6 slides away from the elastic body 12. Inside the gun hole.

There is a scale mark on the traction rope 4, so as to remind the operator of the length of the traction rope 4 lowering.
