[0014] A method for using a mine blasting hole positioning and charge integrated device comprises the following steps: Step 1: After installing the device on the excavator, position the electric puncher at the drilling position of the blasting hole and then start the motor; Step 2: The motor drives the two gears connected by the wheel shaft to rotate, and the gears engage with the rack rail, thereby driving the wheel frame, the electric puncher and the front sliding frame to move downward, and the electric puncher starts drilling into the ground; Step 3: After drilling is completed, the motor drives the gear to reverse, driving the front sliding frame to rise. During the sliding frame's rise, the traction rope pulls the rear sliding frame connected to the injection pipe downward; Step 4: When the front sliding frame rises, it drives the sliding post on the rear side to move. The sliding post slides in the guide tube. When the ball moves to the spiral part in the guide groove, the sliding post rotates 180 degrees, and the sliding frame connected to it rotates synchronously. Step 5: The rotation of the sliding frame drives the lower frame connected to the slide rail to rotate, and the rotating sleeve rotates on the rotating seat, causing the structure including the injection pipe and the electric punch to flip 180 degrees.

[0015] Working principle: After the device is installed on the excavator, the electric puncher on the device is positioned at the drilling position of the blasting hole, and then the motor is started to drive the two gears connected by the wheel frame to rotate, so that the gears are engaged on the rack rail, thereby driving the wheel frame, electric puncher and Qi An Ce's sliding frame connected to it to move downward, driving the started electric puncher to perform positioning drilling work on the ground. After the drilling work is completed, the motor drives the gear to reverse, driving the front sliding frame to continue to rise. During the rising process of the sliding frame, the traction rope connected to it pulls the sliding frame on the rear side connected to the injection pipe to move downward. When the front sliding frame rises, it will also drive the sliding column on the rear side to move, so that the sliding column slides in the guide cylinder and the ball bearings move in the guide groove. When they move to the spiral part of the guide groove, the ball bearings move downward. Under the traction of the spiral part, the traction slide rotates 180°, and the sliding frame connected to the slide is synchronously acted upon by force, rotates, and simultaneously acts upon the lower frame connected to the slide rail, so that the lower frame tends to rotate, and the rotating sleeve connected to the lower frame rotates on the rotating seat, causing the structure connected to the lower frame including the injection pipe and the electric puncher to flip 180°, so that the injection pipe is moved to the position of the blasting hole, and continues to descend under the movement of the sliding frame at the rear side until it is inserted into the blasting hole, and the external device for providing explosive material injects material into the injection pipe through a pipeline, and charges the inside of the blasting hole through the injection pipe. After loading is completed, the device is lifted by the excavator and reset by the motor, and the above-mentioned work process is repeated to continue the positioning, drilling and charging work of the blasting hole at the next point.

DETAILED DESCRIPTION
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Example: As one aspect of the present application, an embodiment of the present invention provides an integrated device for blasthole positioning and charging in a mine, comprising: Please see the attached Figure 1 , Attachment Figure 3 and attached Figure 6 The upper frame 1 is connected to the lower frame 2 on the bottom side of the upper frame 1 through a rotating assembly. The rotating assembly includes a rotating seat 14 fixedly connected to the bottom end of the upper frame 1 and a rotating sleeve 15 fixedly connected to the top end of the upper frame 1. The rotating sleeve 15 is rotatably connected to the bottom side of the rotating seat 14. The front and rear sides of the lower frame 2 are vertically slidable with sliding frames 6 through slide rails 5. The two sliding frames 6 are mirror-imaged, and a lifting assembly is installed on the front side of the front sliding frame 6 to enable the front sliding frame 6 to perform lifting and lowering movements, and the traction assembly is used to affect the rear sliding frame 6 to perform lifting and lowering movements in the opposite direction. An electric puncher 3 for positioning and perforating blasting holes is installed on the front side of the lifting assembly, and an injection pipe 4 for explosive charging is installed on the rear side of the rear sliding frame 6. The top side of the injection pipe 4 is connected to a pipeline for providing explosive material through a flange, and the pipeline is equipped with a valve and other structures for controlling the discharge of the material. Specifically, the position of the bottom center point of the drill bit of the electric puncher 3 and the position of the bottom center point of the injection tube 4 are mirror-symmetrical when they are centered on the rotating seat 14, so that after the electric puncher 3 and the injection tube 4 are exchanged, the injection tube 4 can be accurately aligned with the blasting hole drilled by the electric puncher 3.
[0022] Please see the attached Figure 1 , Attachment Figure 4 and attached Figure 7 , base plate 16, base plate 16 is fixedly connected to the top side of the upper frame 1, and a guide assembly is installed on the bottom side of the base plate 16. When the electric punching machine 3 rises, the guide assembly causes the lower frame 2 to rotate around the rotating assembly, so that the injection pipe 4 moves to the drilling position to perform the charging work of the blasting hole. The guide assembly includes a guide cylinder 17 fixedly connected to the bottom side of the base plate 16 and a slide column 18 fixedly connected to the rear side of the front sliding frame 6. A ball groove is opened on the top of the outer wall of the slide column 18, and a ball 19 is arranged inside the ball groove. The ball 19 rolls and contacts the guide cylinder 1 The guide groove 20 formed on the inner wall of the guide groove 20 has a spiral shape in the middle, and the top and bottom of the guide groove 20 are vertical. The vertical structure at the bottom is to allow the sliding frame 6 to have displacement space for drilling, and the vertical structure at the top is to allow the injection tube 4 to have displacement space for injection. It can also limit the slide post 18 to prevent the structure connected to the slide post 18, including the lower frame 2, from rotating freely. The spiral structure allows the ball 19 to slide inside and drive the slide post 18 to rotate exactly 180 degrees. Please refer to the attached figure. Figure 8The inner wall of the ball groove is provided with an abutment protrusion, which is in rolling contact with the ball 19, and the interior of the ball groove is filled with lubricating oil. The structure of the abutment protrusion allows the ball 19 to keep rotating while ensuring that the ball 19 does not separate. Under the action of the lubricating oil, it maintains lubrication to avoid getting stuck, so that the ball 19 can stably move in the guide groove. The double sealing design ensures long-term lubrication of key movements in the dusty environment of the mine, preventing dust from entering the interior of the ball groove to ensure the normal operation of the ball. Specifically, when the front sliding frame 6 rises, it will also drive the sliding column 18 on the rear side to move, so that the sliding column 18 slides in the guide tube 17 and the ball 19 moves in the guide groove 20. When it moves to the spiral part of the guide groove 20, the ball 19 is pulled by the spiral part to pull the sliding column 18 to rotate 180°. The sliding frame 6 connected to the sliding column 18 is simultaneously acted upon by the force and rotates, and the lower frame 2 connected to the slide rail 5 is simultaneously acted upon by the force, so that the lower frame 2 tends to rotate. The rotating sleeve 15 connected to the lower frame 2 rotates on the rotating seat 14, causing the structure connected to the lower frame 2 including the injection pipe 4 and the electric punch 3 to flip 180°, so that the injection pipe 4 is displaced to the position of the blasting hole.
[0023] Please see the attached Figure 2 , Attachment Figure 4 and attached Figure 5 The lifting assembly includes two rack rails 11 fixedly connected to the left and right sides of the lower frame 2 respectively, the front side of the front sliding frame 6 is fixedly connected to the wheel frame 7, the internal rotation of the wheel frame 7 is connected to the wheel axle 8, the left and right ends of the wheel axle 8 are fixedly connected to the gears 10, the gears 10 and the front sides of the rack rails 11 are meshed with each other, one of the gears 10 is driven by the motor 9 installed on the outer wall of the wheel frame 7, the traction assembly includes a plurality of traction wheels 13 fixedly connected to the top and bottom ends of the inner wall of the lower frame 2, the bottom sides of the two sliding frames 6 and the top sides of the two sliding frames 6 are connected by a traction rope 12, and the rope body of the traction rope 12 is in rolling contact with the traction wheel 13; Specifically, the motor 9 is provided with a locking structure, which enables the drive shaft of the motor 9 to be locked, thereby enabling the gear 10 to be locked in its original position when it does not need to rotate. When the motor 9 drives the two gears 10 connected by the wheel frame 7 to rotate, the gear 10 is engaged on the rack rail 11, thereby driving the wheel frame 7, the electric puncher 3 and the sliding frame 6 of Qi An Ce connected thereto to perform a downward displacement movement. When the front sliding frame 6 is displaced, the traction rope 12 connected thereto pulls the rear sliding frame 6 connected to the injection tube 4 to displace synchronously. The traction rope 12 will pull the rear sliding frame 6 to perform the opposite displacement. When the traction rope 12 is pulled, it will roll in contact with the traction wheel 13, causing the traction wheel 13 to rotate, and then the traction wheel 13 stabilizes its displacement.
[0024] Please see the attached Figure 1 The rear side of the upper frame 1 is fixedly connected with a mounting frame 21 for auxiliary installation, so that it can be installed on an excavator as an accessory of the excavator to perform positioning drilling of blasting holes. The bottom side of the lower frame 2 is fixedly connected with a positioning bottom vertebra 22 for standing on the ground for support.
[0025] Based on the above-mentioned integrated device for blasting blasthole positioning and charging, as another aspect of the present application, a method for using the integrated device for blasting blasthole positioning and charging, comprising the following steps: Step 1: After installing the device on the excavator, position the electric puncher 3 at the drilling position of the blasting hole, and then start the motor 9; Step 2: The motor 9 drives the two gears 10 connected by the wheel shaft 8 to rotate.

During the rising process of the sliding frame 6, the traction rope 12 pulls the rear sliding frame 6 connected to the injection pipe 4 downward; Step 4: When the front sliding frame 6 rises, it drives the sliding post 18 on the rear side to move. The sliding post 18 slides in the guide cylinder 17. When the ball 19 moves to the spiral part in the guide groove 20, the sliding post 18 is pulled to rotate 180 degrees, and the sliding frame 6 connected to it rotates synchronously; Step 5: The rotation of the sliding frame 6 drives the lower frame 2 connected to the slide rail 5 to rotate, and the rotating sleeve 15 rotates on the rotating seat 14, causing the structure including the injection pipe 4 and the electric punch 3 to flip 180 degrees. The injection pipe 4 moves to the blasting hole position and continues to descend under the movement of the rear sliding frame 6 until it is inserted into the blasting hole; Step 6: The external device injects material into the injection pipe 4 through the pipeline.
