Description

Technical Field

[0001] This utility model belongs to the field of mining engineering technology, and specifically relates to a drilling device for mine blasting. Background Technology

[0002] Blasting in mines can quickly remove overlying layers such as rocks and topsoil from the ore body, creating space for subsequent mining operations. The high-temperature, high-pressure gas generated by the explosion can efficiently break hard rocks that are difficult for machinery to handle. Blasting can process large areas of ore and rock in a short time, significantly shortening the mining cycle, and is especially suitable for large-scale operations in open-pit mines. After blasting, the ore and rock are blasted into blocks suitable for mining, loading, and transportation, providing convenient conditions for subsequent excavation, loading, and other processes. Before blasting, holes need to be drilled in the blasting area, and then explosives are filled into the holes. This requires the use of drilling equipment for mining blasting. However, traditional drilling equipment for mining blasting is stored in the limited space of the mine, resulting in high storage pressure. In many areas, carrying or hand-holding drilling equipment is inconvenient. When drilling, the drilling angle is fixed, resulting in low flexibility. After drilling, a large amount of gravel and dust remain in the holes, affecting the uniformity of explosive filling, requiring subsequent cleaning, which is time-consuming and labor-intensive. To solve the problems mentioned above, we propose a drilling equipment for mining blasting. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling device for mining blasting, which has the advantages of multi-angle folding and hole cleaning.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a drilling device for mine blasting, comprising a back plate, a cylinder A bolted to the bottom left side of the back plate, a movable block bolted to the top of the cylinder A, a limit rod rotatably connected through the left side of the front and back sides of the movable block, a rotating box fixedly sleeved on the front and rear ends of the limit rod near the middle, a side plate bolted to the front and rear ends of the left side of the back plate, a limit groove formed on the front and back sides of the side plate, and the interior of the limit groove slidingly connected to the front and rear ends of the limit rod away from the center, a cylinder B bolted to the right side inside the rotating box, a drilling mechanism provided on the left side of the cylinder B, and a cleaning mechanism provided on the top of the rotating box.

[0005] The above technical solution involves cylinder A extending and retracting downwards to move the moving block, which in turn causes the limiting rod to rotate. The limiting rod then moves along the limiting groove, and its rotation causes the rotating box to rotate. This rotation, in turn, causes the drilling mechanism to rotate, resulting in the drill bit folding inwards. After folding, the equipment's volume is significantly reduced, making it easier to store in the limited space of a mine and reducing storage pressure. The equipment can be quickly unfolded or folded to adapt to complex mine terrain and varying working conditions, shortening preparation time. The drilling direction can be adjusted at multiple angles, improving drilling flexibility. The equipment can quickly adjust its angle in complex environments such as narrow tunnels and uneven mine working faces to adapt to different terrain requirements.

[0006] The present invention is further configured such that the cleaning mechanism includes an L-plate, which is bolted to the top of the rotating box. A motor B is rotatably connected to the center of the right side of the L-plate. An inclined plate is fixedly sleeved at the left output end of the motor B. A movable groove is opened at the top left side of the inclined plate. A movable joint is movably sleeved inside the movable groove. A C-rod is bolted to the left side of the movable joint. A bracket is hinged to the front and rear ends of the inner wall of the C-rod. A rotating rod is bolted to the opposite side of the two brackets. The bottom of the rotating rod is rotatably connected to the left side of the top of the L-plate. A bellows is bolted to the top of the rotating rod. A telescopic connecting pipe is sleeved on the right side of the bellows. A fan is connected to the end of the telescopic connecting pipe away from the bellows. The surface of the fan is embedded in the top left side of the back plate. An air inlet pipe is connected to the top of the fan. The surface of the air inlet pipe penetrates the top of the back plate. An air outlet pipe is sleeved on the left side of the bellows.

[0007] The above technical solution employs a cleaning mechanism. The blower draws air in through the inlet pipe, blows it into the telescopic connecting pipe, enters the air box through the telescopic connecting pipe, and exits through the outlet pipe. Motor B drives the inclined plate to rotate, which in turn drives the movable groove to rotate. The movable groove then moves the movable joint, which in turn moves plate C. Plate C then drives the rotating rod to rotate back and forth, causing the outlet pipe to swing back and forth. This process removes debris such as gravel and soil from the hole during drilling, preventing the drill bit from getting stuck or worn. The hole is free of sediment after cleaning, increasing drilling speed and depth. Clean holes ensure even filling of explosives, reducing energy loss and creating a neater blasting section, thus creating favorable conditions for blasting.

[0008] The present invention is further configured such that the drilling mechanism includes a drive box, a motor A is bolted to the right side inside the drive box, and the surface of the output end of the motor A is rotatably connected to the left side of the drive box, and a drill bit is fixedly sleeved on the left side of the motor A.

[0009] The above technical solution is adopted: by setting up a drilling mechanism, the cylinder B extends and retracts to drive the drive box to move, and the motor A drives the drill bit to rotate, so that the drill bit can rotate and extend at the same time.

[0010] The present invention is further configured such that a slider A is bolted to the right side of the movable block, a groove A is provided at the center of the left side of the back plate, and the interior of the groove A is slidably connected to the surface of the slider A; slider B is bolted to the left side of the top and bottom of the interior of the rotating box; and grooves B are provided at the top and bottom of the drive box, and the interior of the groove B is slidably connected to the surface of the slider B.

[0011] The above technical solution is adopted: by setting slide groove A and slider A, the movement of the moving block can be limited; by setting slide groove B and slider B, the movement of the drive box can be limited.

[0012] The present invention is further configured such that a filter screen is fitted onto the top of the fan.

[0013] The above technical solution, by setting up a filter, can prevent dust and gravel from entering the fan.

[0014] The present invention is further configured such that a handle is fitted onto the opposite side of the cylinder A and the back plate.

[0015] The above technical solution incorporates a handle for easy gripping.

[0016] The present invention is further configured such that the right side of the motor B is bolted to the housing, and the left side of the housing is bolted to the top and bottom of the right side of the L plate.

[0017] By adopting the above technical solution, a housing is installed to prevent dust from entering motor B.

[0018] The present invention is further provided that the surface of the grip is provided with anti-slip texture.

[0019] The above technical solution, by setting anti-slip texture, makes the device more stable when held.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. The device volume is greatly reduced after folding, which makes it easy to store in the limited space of the mine and reduces storage pressure. The device can be quickly unfolded or folded to adapt to the complex terrain and changing working conditions of the mine, shorten the preparation time.

After cleaning, there is no sediment at the bottom of the hole, which improves the drilling speed and depth. The clean hole can ensure that the explosive is filled evenly, reduce energy loss, make the blasting cross section more neat, and create favorable conditions for subsequent blasting.
