Description

Technical Field

[0001] This utility model relates to the field of mining blasting rod technology, and more specifically to a blasting rod for mining blasting. Background Technology

[0002] Mining refers to production activities that obtain energy and raw materials by mining underground mineral resources. Mineral resources are formed by long-term geological processes of the earth's crust and are classified into categories such as energy, metals, and non-metals. Mining blasting is a core method that uses the explosive energy of explosives to break rocks and achieve the stripping or excavation of ore bodies. It is widely used in open-pit mines, underground mines, and special engineering scenarios. During the blasting process, the blasting rod is the core tool for loading explosives, detonators, and blasting mud. It is also used to detect the angle, depth, and internal conditions of the blast hole (such as whether the hole wall is flat and whether there is water accumulation).

[0003] During blasting, the blast holes are often too deep, and the existing blasting rods are generally of limited length, making them inconvenient to use. Secondly, in order to adapt to different hole depths, blasting rods are often connected using connectors, but the existing connectors are cumbersome to fix, and installation and disassembly take a certain amount of time, which is not conducive to use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a blasting rod for mining to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a blasting ram for mining, comprising a handle and a quick-connect component. The quick-connect component is fixedly connected to one side of the handle. Fixing devices are movably connected to the top and bottom sides of the quick-connect component. A connecting rod is fixedly connected to one side of the quick-connect component. The quick-connect component includes a quick-connect body. Receiving grooves are formed at the top and bottom of the quick-connect body near the sides. The receiving grooves are arc-shaped recessed grooves. Insertion blocks are fixedly connected to both sides of the quick-connect body.

[0006] Furthermore, the handle includes a rod body, a retaining ring is fixedly connected to the other side of the rod body, and a handle is fixedly connected to the other side of the retaining ring.

[0007] Furthermore, the fixing device includes a control rod, a connecting plate is fixedly connected to the bottom of the control rod, a limit block is fixedly connected to one side of the top of the connecting plate, and a plug-in block is movably connected to the outer side of the limit block.

[0008] Furthermore, a telescopic spring is fixedly connected to the other side of the bottom of the connecting plate, and a base plate is fixedly connected to the bottom of the telescopic spring. A support rod is provided inside the telescopic spring, and the bottom of the support rod is fixedly connected to the base plate.

[0009] Furthermore, the length of the support rod is less than the length of the telescopic spring, and the distance between the top of the support rod and the bottom of the connecting plate is the same as the length of the limiting block located outside the top of the plug-in block.

[0010] Furthermore, the connecting rod includes a connecting rod body, and the connecting rod body has insertion slots on both sides. The insertion slots are adapted to the insertion blocks. The insertion slots have limiting slots inside, and the limiting slots are evenly distributed in hexagons. The limiting slots are adapted to the limiting blocks.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model has a quick-connect component. By pressing the control rod, the limiting block moves into the insertion block. By inserting the insertion block into the insertion slot and releasing the control rod, the limiting block and the limiting slot are fixed in place. This facilitates the quick connection of multiple connecting rods and allows the length of the gun barrel to be adapted to different gun hole depths.

[0013] 2. This utility model has a fixing device. By pressing the control rod, the control rod moves the connecting plate towards the inside of the quick-connect piece, thereby moving the limiting block towards the inside of the insertion block. When the connecting plate moves to contact the support rod, the top of the limiting block moves into the inside of the insertion block. When the control rod is released, the connecting plate moves back to its original position under the elastic force of the telescopic spring. This facilitates quick control of the movement of the limiting block by pressing and releasing the control rod. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The blasting ram for mining involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4 This utility model provides a blasting ram for mining, including a handle 1 and a quick-connect component 2. The quick-connect component 2 is fixedly connected to one side of the handle 1. Fixing devices 3 are movably connected to the top and bottom sides of the quick-connect component 2. A connecting rod 4 is fixedly connected to one side of the quick-connect component 2. The quick-connect component 2 includes a quick-connect body 201. Receiving grooves 202 are opened at the top and bottom of the quick-connect body 201 near the sides. The receiving grooves 202 are arc-shaped recessed grooves. Insertion blocks 203 are fixedly connected to both sides of the quick-connect body 201. By pressing the control rod 301, the limiting block 303 moves into the insertion block 203. By inserting the insertion block 203 into the insertion groove 402 and releasing the control rod 301, the limiting block 303 is fixedly positioned with the limiting groove 403. This facilitates the quick connection of multiple connecting rods 4, allowing the length of the blasting ram to adapt to different blast hole depths.

[0021] In a preferred embodiment, the handle 1 includes a rod 101, a retaining ring 102 is fixedly connected to the other side of the rod 101, and a handle 103 is fixedly connected to the other side of the retaining ring 102.

[0022] In a preferred embodiment, the fixing device 3 includes a control rod 301, a connecting plate 302 is fixedly connected to the bottom of the control rod 301, a limit block 303 is fixedly connected to one side of the top of the connecting plate 302, and a plug-in block 203 is movably connected to the outer side of the limit block 303.

[0023] In a preferred embodiment, a telescopic spring 304 is fixedly connected to the other side of the bottom of the connecting plate 302. A base plate 305 is fixedly connected to the bottom of the telescopic spring 304. A support rod 306 is provided inside the telescopic spring 304. The bottom of the support rod 306 is fixedly connected to the base plate 305. By pressing the control rod 301, the control rod 301 drives the connecting plate 302 to move inward toward the quick connector 2, thereby driving the limiting block 303 to move inward toward the insertion block 203. When the connecting plate 302 moves to contact the support rod 306, the top of the limiting block 303 moves into the insertion block 203. When the control rod 301 is stopped and released, the connecting plate 302 moves back to its original position under the elastic force of the telescopic spring 304. This facilitates the rapid control of the movement of the limiting block 303 by pressing and releasing the control rod 301.

[0024] In a preferred embodiment, the length of the support rod 306 is less than the length of the telescopic spring 304, and the distance between the top of the support rod 306 and the bottom of the connecting plate 302 is the same as the length of the limiting block 303 located outside the top of the plug block 203.

[0025] In a preferred embodiment, the connecting rod 4 includes a connecting rod body 401, with insertion slots 402 on both sides of the connecting rod body 401.

The limiting slots 403 are uniformly distributed in hexagons and are adapted to the limiting blocks 303.

[0026] The working principle of this utility model:

[0027] By pressing the control lever 301, the bottom of the control lever 301 moves to the bottom of the receiving groove 202, causing the limiting block 303 to move into the insertion block 203. Simultaneously, the arc-shaped concave structure of the receiving groove 202 facilitates pressing the control lever 301. By inserting the insertion block 203 into the insertion groove 402 and releasing the control lever 301, the limiting block 303 is fixed to the limiting groove 403, facilitating the rapid connection of multiple connecting rods 4 and allowing the length of the gun barrel to adapt to different gun hole depths. Pressing the control lever 301... 1. The control lever 301 drives the connecting plate 302 to move inward toward the quick connector 2, thereby driving the limiting block 303 to move inward toward the insertion block 203. When the connecting plate 302 moves to contact the support rod 306, the top of the limiting block 303 moves into the insertion block 203. When the control lever 301 is stopped and released, the connecting plate 302 moves back to its original position under the elastic force of the telescopic spring 304. This facilitates the rapid control of the movement of the limiting block 303 by pressing and releasing the control lever 301.
