Description

Technical Field

[0001] This utility model relates to the field of explosive loading rod technology, and in particular to an explosive loading rod for rock blasting. Background Technology

[0002] As the scale of mineral mining continues to expand, the requirements for explosive loading efficiency are also increasing. Traditional manual loading methods are slow and cannot meet the needs of large-scale mining. In a large mine, there may be hundreds or thousands of blast holes that need to be loaded with explosives. If each blast hole is loaded slowly by hand, it will greatly extend the mining cycle. This will not only increase production costs but also affect the economic benefits of the mine. Moreover, the efficiency of manual loading is also affected by the operator's skill level. New operators may be slower in loading and the loading quality is difficult to guarantee. Therefore, a tool that can improve loading efficiency and ensure loading quality is needed to solve these problems.

[0003] Existing equipment requires manual filling of explosives into blast holes, and the amount of explosives filled is difficult to control, placing it in a highly dangerous environment. Explosives are highly sensitive; accidental impacts, friction, or static electricity during filling can trigger an explosion, posing a serious threat to the lives of operators. Furthermore, the inability to precisely control the amount of explosives filled into each blast hole makes the blasting effect unpredictable, potentially failing to achieve the desired results. For example, it may not completely break up the ore, affecting mining efficiency and requiring additional re-blasting operations, increasing costs and time.

[0004] Therefore, there is an urgent need to provide an explosive loading rod for rock blasting to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an explosive loading rod for rock blasting.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution: a loading rod for explosives used in rock blasting, comprising a connecting plate, a handle fixedly connected to the bottom of the connecting plate, a pushing assembly installed on the top of the connecting plate, a support member fixedly connected to one side of the top of the connecting plate, a guide pipe fixedly connected to one side of the outer wall of the support member, two fixing plates fixedly connected to one side of the outer wall of the connecting plate, a feeding assembly installed between the two fixing plates, and a feeding port opened at the top of the guide pipe.

[0007] The present invention is further configured such that: the pushing assembly includes two sliding grooves formed on the top of the connecting plate, and multiple sliders are slidably connected to the inner walls of the two sliding grooves; a pushing box is fixedly connected between the tops of the multiple sliders; a rotating rod is rotatably connected to one side of the outer wall of the pushing box; a rotating wheel is fixedly connected to the outer wall of the rotating rod; a rotating rod is fixedly connected to the front end of the rotating rod; multiple transmission teeth are fixedly connected to the top of the connecting plate; an installation plate is fixedly connected to one side of the inner wall of the pushing box; and a pushing rod is fixedly connected to one side of the outer wall of the installation plate.

[0008] The above technical solution involves first rotating the rotating rod clockwise, which then drives the rotating rod to rotate synchronously. Simultaneously, the rotating rod drives the rotating wheel to rotate synchronously. Subsequently, multiple transmission teeth cause the entire pusher box to move horizontally. Then, the pusher box drives the mounting plate to move horizontally synchronously, and the mounting plate then drives the pusher rod to move horizontally synchronously.

[0009] The present invention is further configured such that the outer walls of the plurality of sliders are in close contact with the inner walls of the corresponding sliding grooves, and that every two sliders are parallel to each other.

[0010] The above technical solution can prevent the slider from wobbling left and right or up and down during the movement, ensuring that the movement direction of the push box is always along the direction of the sliding groove. At the same time, it ensures that the load borne by each slider can be evenly distributed during the movement of the push box.

[0011] The present invention is further configured such that: the inner wall of the rotating wheel matches the outer wall of the rotating rod, and the rotating wheel meshes with multiple transmission teeth.

[0012] With the above technical solution, when the inner wall of the rotating wheel matches the outer wall of the rotating rod, the connection between them is tighter and more stable. During the process of the rotating rod driving the rotating wheel to rotate, this tight match can prevent relative slippage or loosening between the two.

[0013] The present invention is further configured such that: the feeding assembly includes a fixed rod fixedly connected to two fixed plates, a feeding tank fixedly connected between the inner walls of the two fixed rods, a feeding port provided at the top of the feeding tank, a transmission rod rotatably connected to the center of the top of the feeding tank, a rotating ring fixedly connected to the top of the outer wall of the transmission rod, a glass cover fixedly connected to the outer wall of the feeding tank, scale lines provided on the outer wall of the glass cover, and multiple stirring rods fixedly connected to the outer wall of the transmission rod.

[0014] The above technical solution involves first feeding explosives into the feeding tank through the feeding port, then observing the amount of explosives fed through the scale lines until the specified scale is reached, and then rotating the rotating ring to drive the transmission rod to rotate synchronously, which in turn drives multiple stirring rods to rotate synchronously.

[0015] The present invention is further configured such that: the bottom of the feeding tank is parallel to the inlet, and the bottom of the outer wall of the feeding tank fits into the inner wall of the inlet.

[0016] With the above technical solution, when the bottom of the feeding tank is parallel to the inlet, the process of explosives flowing from the feeding tank to the inlet will be smoother, and the fit between the bottom of the outer wall of the feeding tank and the inner wall of the inlet can prevent leakage of explosives during the transmission process.

[0017] The present invention is further configured such that each pair of stirring rods is arranged at a 90° angle, and the distance between each pair of stirring rods is equal.

[0018] The above technical solution can change the flow direction of explosives in the feeding tank, so that the material is sheared and pushed by the stirring rod in different directions, preventing the material from continuously accumulating in a certain fixed direction, thereby reducing the possibility of blockage.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up a feeding component, this utility model allows the explosive filling process to be operated from a relatively safe distance, avoiding the safety risks caused by direct manual contact with explosives and reducing the risk of accidental explosions caused by close manual operation;

[0021] 2. By setting up a feeding component, this utility model can accurately control the amount of explosive entering the loading rod each time, ensuring that the amount of explosive loaded each time meets the blasting design requirements. By accurately measuring and controlling the feeding amount, it can avoid affecting the performance of the explosive and the blasting effect due to too much or too little feeding.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Please see Figure 1 - Figure 6A loading rod for explosives used in rock blasting includes a connecting plate 1, a handle 2 fixedly connected to the bottom of the connecting plate 1, and a pushing assembly 3 installed on the top of the connecting plate 1. The pushing assembly 3 includes two sliding grooves 301 formed on the top of the connecting plate 1, with multiple sliders 302 slidably connected to the inner walls of the two sliding grooves 301. A pushing box 303 is fixedly connected between the tops of the multiple sliders 302, and a rotating rod 304 is rotatably connected to one side of the outer wall of the pushing box 303. A rotating wheel 30 is fixedly connected to the outer wall of the rotating rod 304. 5. A rotating rod 306 is fixedly connected to the front end of the rotating rod 304. Multiple transmission teeth 307 are fixedly connected to the top of the connecting plate 1. A mounting plate 308 is fixedly connected to one side of the inner wall of the pusher box 303, and a pusher rod 309 is fixedly connected to one side of the outer wall of the mounting plate 308. First, the rotating rod 306 is rotated clockwise. Then, the rotating rod 306 will drive the rotating rod 304 to rotate synchronously. At the same time, the rotating rod 304 will drive the rotating wheel 305 to rotate synchronously. Subsequently, the multiple transmission teeth 306... 7. The pusher box 303 is moved horizontally as a whole, and then the pusher box 303 drives the mounting plate 308 to move horizontally synchronously. Subsequently, the mounting plate 308 drives the pusher rod 309 to move horizontally synchronously. The outer walls of multiple sliders 302 are tightly fitted with the inner walls of the corresponding sliding grooves 301, and every two sliders 302 are parallel to each other. This can prevent the sliders 302 from wobbling left and right or up and down during the movement, ensuring that the movement direction of the pusher box 303 is always along the direction of the sliding groove 301. At the same time, it ensures that the load borne by each slider 302 can be evenly distributed during the movement of the pusher box 303. The inner wall of the rotating wheel 305 matches the outer wall of the rotating rod 304, and the rotating wheel 305 meshes with multiple transmission teeth 307. When the inner wall of the rotating wheel 305 matches the outer wall of the rotating rod 304, the connection between them is tighter and more stable. During the rotation of the rotating rod 304 driving the rotating wheel 305 to rotate, this tight matching can prevent relative sliding or loosening between the two.

[0031] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a support member 4 is fixedly connected to one side of the top of the connecting plate 1, a guide pipe 5 is fixedly connected to one side of the outer wall of the support member 4, two fixed plates 6 are fixedly connected to one side of the outer wall of the connecting plate 1, and a feeding assembly 7 is installed between the two fixed plates 6. The top of the guide pipe 5 has a feed inlet 8. The feeding assembly 7 includes a fixed rod 701 fixedly connected to the two fixed plates 6, a feeding tank 702 is fixedly connected between the inner walls of the two fixed rods 701, a feeding port 703 is provided at the top of the feeding tank 702, a transmission rod 704 is rotatably connected to the center of the top of the feeding tank 702, a rotating ring 705 is fixedly connected to the top of the outer wall of the transmission rod 704, a glass cover 706 is fixedly connected to the outer wall of the feeding tank 702, a scale line 707 is provided on the outer wall of the glass cover 706, and multiple stirring rods 708 are fixedly connected to the outer wall of the transmission rod 704. First, the explosive is transported into the feeding tank 702 through the feeding port 703, and then the feeding of the explosive is observed through the scale line 707. The quantity is increased until the specified scale is reached. Then, the rotating ring 705 is rotated, causing the transmission rod 704 to rotate synchronously. The transmission rod 704 then drives multiple stirring rods 708 to rotate synchronously. The bottom of the feeding tank 702 is parallel to the feed inlet 8, and the bottom of the outer wall of the feeding tank 702 fits into the inner wall of the feed inlet 8. When the bottom of the feeding tank 702 is parallel to the feed inlet 8, the flow of explosives from the feeding tank 702 to the feed inlet 8 is smoother. The fit between the bottom of the outer wall of the feeding tank 702 and the inner wall of the feed inlet 8 prevents leakage of explosives during transmission. Each pair of stirring rods 708 is set at a 90° angle, and the distance between each pair of stirring rods 708 is equal. This can change the flow direction of explosives in the feeding tank 702, so that the material is sheared and pushed by the stirring rods 708 in different directions, preventing the material from continuously accumulating in a fixed direction, thereby reducing the possibility of blockage.

[0032] In use, the explosives are first fed into the feeding tank 702 through the feeding port 703. The amount of explosives fed is then observed through the scale line 707 until the specified scale is reached. Then, the rotating ring 705 is rotated, causing the transmission rod 704 to rotate synchronously. The transmission rod 704 then drives multiple stirring rods 708 to rotate synchronously, causing the rotating rod 306 to rotate clockwise. The rotating rod 306 then drives the rotating rod 304 to rotate synchronously. At the same time, the rotating rod 304 drives the rotating wheel 305 to rotate synchronously. Then, the pusher box 303 is moved horizontally through multiple transmission teeth 307. The pusher box 303 then drives the mounting plate 308 to move horizontally. The mounting plate 308 then drives the pusher rod 309 to move horizontally. Finally, the pusher rod 309 pushes the explosives out of the guide tube 5.
