[0015] S1. Installation and placement: First, twist the adjusting screw according to the ground conditions next to the blasthole. The adjusting screw drives the left and right movable plates to move synchronously inward and outward. When the movable plate moves and the tapered rod moves to the appropriate position, stop twisting the adjusting screw to make the detection head align with the blasthole. Insert the tapered rod into the ground to fix the movable plate on the ground.

[0016] S2, detection, start the electric sliders on the left and right sides to move toward each other, the electric sliders drive the vertical rods to move downward through the connecting rods, the vertical rods move downward and the detection head moves downward, at the same time the vertical rods drive the horizontal plate to move downward, the horizontal plate drives the spiral rod to rotate through the sphere, the spiral rod drives the annular brush to rotate through the spur gear and the outer gear ring, the annular brush rotates to remove impurities such as metal ore powder on the detection head, and the detection head after removing impurities detects the quality of the blasthole;

A driving assembly is provided between the vertical rod 3 and the L-shaped frame 7. The driving assembly is used to drive the outer ring gear 10 to rotate, and the outer ring gear 10 drives the annular brush 9 to rotate, so that the annular brush 9 can remove impurities such as metal ore powder before and after use of the detection head 4.

[0035] See also Figure 2 As shown, the adjustable support assembly includes a movable plate 6, an adjusting screw 61 and a tapered rod 62. The movable plate 6 is symmetrically slidably connected to the fixed base 1 on the left and right sides. The movable plate 6 can support and limit the fixed base 1. The outer end bottoms of the left and right movable plates 6 are symmetrically fixed with tapered rods 62 front and back. The upper part of the fixed base 1 is symmetrically rotatably connected with the adjusting screw 61 on the left and right sides. The adjusting screws 61 on the left and right sides are respectively threadedly connected to the upper parts of the left and right movable plates 6. When the adjusting screw 61 rotates, the adjusting screw 61 can drive the movable plate 6 to move left and right to adjust the position of the support.

[0036] See also Figure 3 and Figure 4 As shown, the drive assembly includes a spur gear 11, a screw rod 111, a horizontal plate 112 and a ball 113. The screw rod 111 is vertically rotatably connected to the bottom right side of the L-shaped frame 7. The lower part of the screw rod 111 is fixedly sleeved with a spur gear 11, and the spur gear 11 is engaged with the outer gear ring 10. The top of the vertical rod 3 is laterally fixed with a horizontal plate 112, and the left side of the horizontal plate 112 is slidably sleeved on the screw rod 111. A ball 113 is fixed in the sleeve hole of the horizontal plate 112, and the ball 113 is in contact with the spiral groove of the screw rod 111. When the ball 113 moves up and down, the ball 113 can drive the screw rod 111 to rotate.

[0037] First, move the device to the blasthole position, and according to the ground conditions next to the blasthole, twist the adjusting screw 61 to rotate. The rotation of the adjusting screw 61 drives the movable plates 6 on the left and right sides to move synchronously inward and outward, and the movable plates 6 drive the tapered rods 62 on the left and right sides to move synchronously inward and outward. When the movable plates 6 move inward and outward to a position suitable for supporting the fixed seat 1, stop twisting the adjusting screw 61, and the movable plate 6 stops driving the tapered rod 62 to move inward and outward. In this way, the position of the tapered rod 62 can be adjusted according to the conditions of the ground next to the blasthole to adapt to different ground conditions next to the blasthole. The mobile fixed seat 1 drives the connecting rod 5 to move through the electric slider 2, and the connecting rod 5 drives the detection head 4 to move through the vertical rod 3, so that the detection head 4 is exactly corresponding to the blasthole. Then put the device down, and the fixed seat 1 drives the connecting rod 5 to move through the movable plate 6. The tapered rod 62 moves downward, and the tapered rod 62 moves downward and is inserted into the ground. The tapered rod 62 fixes the movable plate 6 on the ground, and then starts the left and right electric sliders 2 to move in the direction of approaching each other. The electric sliders 2 drive the upper parts of the left and right connecting rods 5 to move in the direction of approaching each other. The upper part of the connecting rod 5 moves in the direction of approaching each other so that the lower part moves downward. The downward movement of the lower part of the connecting rod 5 drives the detection head 4 to move downward. At the same time, the downward movement of the vertical rod 3 also drives the horizontal plate 112 to move downward. The downward movement of the horizontal plate 112 drives the ball 113 to move downward. The downward movement of the ball 113 drives the screw rod 111 to rotate. The rotation of the screw rod 111 drives the spur gear 11 to rotate. The rotation of the spur gear 11 drives the outer ring gear 10 to rotate. The rotation of the outer ring gear 10 drives the annular brush 9 to rotate. The annular brush 9 rotates to clean the detection head 4 moving downward, that is, to remove impurities such as metal ore powder attached to the detection head 4. After removing the impurities, the detection head 4 continues to move downward into the blasthole. When the detection head 4 moves downward to the detection position in the blasthole, the electric slider 2 is closed, the vertical rod 3 stops driving the detection head 4 and the horizontal plate 112 to move downward, the horizontal plate 112 stops driving the ball 113 to move downward, the ball 113 stops driving the screw rod 111 to rotate, the screw rod 111 stops driving the spur gear 11 to rotate, the outer gear ring 10 stops driving the annular brush 9 to rotate, and then the detection head 4 is started. The detection head 4 detects the diameter, depth and humidity of the inner wall of the blasthole. The humidity measurement can prevent the explosives from getting damp, thereby improving the blasting effect. In this way, The inspection of the blasthole quality can be completed. When the blasthole quality inspection is completed, the left and right electric sliders 2 are started to move away from each other and reset. The electric slider 2 drives the vertical rod 3 to move upward and reset through the connecting rod 5. The vertical rod 3 moves upward and resets, driving the detection head 4 and the horizontal plate 112 to move upward and reset. The horizontal plate 112 moves upward and drives the ball 113 to move upward. The ball 113 moves upward and drives the screw rod 111 to rotate in the opposite direction. The screw rod 111 drives the spur gear 11 to rotate in the opposite direction. The spur gear 11 drives the outer gear ring 10 to rotate in the opposite direction. The outer gear ring 10 drives the annular brush 9 to rotate in the opposite direction. The annular brush 9 rotates in the opposite direction to clean the detection head 4 after use, so as to remove impurities such as metal ore powder attached to the detection head 4 to ensure that the detection head 4 is clean.Once the inspection head 4 is reset, the motorized slide 2 is closed, the annular brush 9 stops rotating, and the device can be lifted, allowing the movable plate 6 to move the tapered rod 62 upward and out of contact with the ground. The adjusting screw 61 is then rotated in the opposite direction, driving the left and right movable plates 6 toward each other and into their original position. This, through the action of the annular brush 9, automatically removes impurities such as metal ore powder from the inspection head 4, preventing them from adhering and affecting the inspection, thereby improving the accuracy of blasthole quality inspection.

[0038] See also Figure 5 and Figure 6 As shown, the deep hole blasthole quality detection device in the underground metal mine also includes a stabilizing component installed on the movable plate 6, the stabilizing component includes an air bag 12, a support sleeve 121, a cylinder body 122, a screw rod 123, a piston block 124 and a connecting pipe 125, the lower parts of the movable plates 6 on the left and right sides are fixedly connected with the support sleeve 121, the cylinder body 122 is fixedly arranged on the support sleeve 121 on the corresponding side, and the bottoms of the movable plates 6 on the left and right sides are fixedly connected with the air bags 12. When the air bags 12 are inflated, the air bags 12 can support the movable plates 6 so that the movable plates 6 are more firmly on the ground. The tops of the air bags 12 on the left and right sides are fixedly connected with the air bags 12. Both are connected to a connecting pipe 125. The top ends of the connecting pipes 125 on the left and right sides respectively penetrate the lower part of the left and right movable plates 6, the support sleeve 121 and the bottom of the cylinder body 122. The airbag 12 is connected with the cylinder body 122 on the corresponding side through the connecting pipe 125 thereon. A piston block 124 is slidably connected in the cylinder body 122. A screw rod 123 is threadedly connected to the middle of the top of the cylinder body 122. The bottom end of the screw rod 123 is vertically downward and rotatably connected to the middle of the top of the piston block 124. When the screw rod 123 rotates, the screw rod 123 can drive the piston block 124 to move up and down to push air into the connecting pipe 125.

[0039] See also Figure 7-Figure 9As shown, the deep hole blasthole quality inspection device for underground metal mines also includes a horizontal inspection component, which includes a mounting plate 13, a hollow tube 131, a guide plate 132, a ball 133 and a positioning component. The middle part of the front side of the fixed seat 1 is fixedly connected to the mounting plate 13, and the lower part of the front side of the mounting plate 13 is fixedly connected to the hollow tube 131. A rollable ball 133 is placed in the hollow tube 131, and the ball 133 can inspect the horizontal position of the hollow tube 131. The middle part of the front side of the movable plates 6 on the left and right sides is fixedly connected to the guide plate 132, and the front side of the guide plate 132 is slidably mounted on the outer side of the hollow tube 131. The guide plate 132 can support and guide the hollow tube 131. A positioning component is provided on the hollow tube 131. When the positioning component is in operation, the positioning component can position the ball 133. The positioning assembly includes a guide rod 134, a positioning plate 135 and a return spring 136. The front side of the hollow tube 131 has a straight hole 1321 along its length. A guide rod 134 is fixed between the left and right sides of the hollow tube 131. The guide rod 134 is parallel to the hollow tube 131. A positioning plate 135 is symmetrically slidably connected between the guide rod 134 and the inner side of the hollow tube 131. The positioning plate 135 passes through the straight hole 1321. The positioning plates 135 slide with the straight hole, the inner wall of the hollow tube 131 and the guide rod 134. When the positioning plate 135 moves to contact the ball 133, the positioning plate 135 can position the ball 133. The left and right positioning plates 135 are away from each other and are respectively connected to the left and right ends of the hollow tube 131 with a return spring 136, which is sleeved on the guide rod 134.

[0040] When the tapered rod 62 is inserted into the ground, the screw rod 123 is twisted and rotated forward to move downward through the thread. The screw rod 123 moves downward to drive the piston block 124 to move downward. The piston block 124 moves downward to push the air in the cylinder 122 into the connecting pipe 125. The air in the connecting pipe 125 is discharged into the air bag 12. As the air is discharged, the air bag 12 continues to expand and contact the ground. The expansion of the air bag 12 increases the contact area with the ground. The air bag 12 supports and limits the movable plate 6, making the movable plate 6 more stable. On the ground, stop twisting the screw rod 123, the piston block 124 stops moving downward, and the device can be operated to detect the quality of the blasthole. When the blasthole quality detection is completed, twist the screw rod 123 in the opposite direction and move it upward to reset. The screw rod 123 moves upward to drive the piston block 124 to move upward to reset. The piston block 124 moves upward to draw the air in the air bag 12 back into the cylinder 122 through the connecting pipe 125. As the air is drawn out, the air bag 12 continuously contracts and resets, and the twisting of the screw rod 123 is stopped. In this way, the movable plate 6 can be placed more firmly on the ground, and the device can be used to detect the quality of the blasthole more firmly.

[0041] When the movable plates 6 on the left and right sides move, the movable plates 6 drive the guide plates 132 to move, and the guide plates 132 slide on the hollow tube 131. When the movable plates 6 stop moving, the movable plates 6 stop driving the guide plates 132 to move, and the guide plates 132 support and limit the hollow tube 131. Then, after the tapered rods 62 are inserted into the ground to fix the movable plates 6, the operator pulls the left and right positioning plates 135 to move toward each other, and the return springs 136 are stretched. The left and right positioning plates 135 move toward each other and contact with the ball 133. The positioning plates 135 center the ball 133, and then release the positioning plates 135. 5. Due to the action of the return spring 136, the left and right positioning plates 135 move away from each other and reset. The positioning plates 135 reset and disengage from the ball 133. The operator then observes the position of the ball 133. If the ball 133 moves to the left or right, it means that the entire device is in a tilted state, and the detection head 4 is no longer aligned with the blasthole. The movable plate 6 corresponding to the movement direction of the ball 133 can be pulled upward to move the iron ball to the center of the hollow tube 131. This indicates that the detection head 4 is adjusted to the position aligned with the blasthole, and then the blasthole quality inspection can be started. In this way, the deviation of the detection head 4 position can be prevented from affecting the detection of the blasthole quality, thereby further improving the detection of the blasthole quality by the detection head 4.

[0042] See also Figure 10 As shown, the deep hole blasthole quality detection device in the underground metal mine also includes an electric support rod 14. The electric support rods 14 are symmetrically installed on the lower outer ends of the left and right movable plates 6 in the front and back, and the electric support rods 14 can support the movable plates 6.

[0043] When it is necessary to use this device, first start the electric support rod 14 and swing it upward to a suitable position. Then, when the movable plate 6 is fixed to the ground through the tapered rod 62, start the electric support rod 14 and swing it downward to contact the ground. The electric support rod 14 is closed, and the electric support rod 14 supports and limits the front and rear sides of the movable plate 6. When it is not necessary to use this device and the movable plate 6 is picked up from the ground, start the electric support rod 14 and swing it downward to reset it to a vertical state and put it away. The electric support rod 14 is put away for easy subsequent carrying. In this way, the movable plate 6 can be placed more firmly without affecting the detection of the quality of the blasthole.
