Description

Technical Field

[0002] Most conventional underground metal mining blasting work uses nitrate metal particles as explosives. At present, in underground metal mining, blasting is carried out by first drilling some holes distributed in a certain way on the rock steps to be blasted. At present, drilling blasting is one of the best methods used in underground metal mining blasting methods. The drilling blasting method is to add explosives after drilling holes in the rock steps, and then use the explosive force of the explosives themselves to blast the mine. The existing blasting drilling equipment is generally composed of a drill rod, a drive motor and a frame. After the equipment is moved to the drilling position, the drill rod is driven to rotate and move downward to drill holes. After the drilling is completed, the drill rod is taken out, and explosives are placed in the drilling position for fixed-point blasting. However, there are the following defects:

[0003] When the drilling device is drilling, as the drill rod is drilled into the borehole, the gravel generated by the drilling is continuously discharged outward. When the drilling force is large, the gravel is easy to jump out, and the gravel is easy to collide with the device and personnel, thereby causing personal injury and damage to the device. At the same time, as the drill rod is drilled into the borehole, gravel is continuously accumulated on the outside of the borehole at the drilling position, and it is not easy to push the gravel outward during drilling, which affects the subsequent discharge of gravel and thus hinders the drilling work.

[0044] Working principle: when working, first move the equipment to the position where the coal mine water prevention and control drilling is required, turn on the first motor 6, so that the embedded drill rod 5 rotates, and turn on the second motor 9 at the same time. Since the screw 8 is threadedly connected to the horizontal platform 4, the horizontal platform 4 moves downward, so that the embedded drill rod 5 moves downward, and the position where the drilling is required is continuously drilled. Since the protective tube 1001 is sleeved on the outside of the embedded drill rod 5, when in use, turn on the cylinder 1004, so that the output end of the cylinder 1004 extends downward, pushing the cylinder 1004 to move downward until the bottom rod 1005 moves downward. At this time, the bottom end of the push plate 1101 contacts the ground at the position where the drilling is required, thereby blocking the stones splashed out when the embedded drill rod 5 is drilled, thereby improving the protection effect. At the same time, the protective tube 1001 can be adjusted in height through the cylinder 1004, which is convenient for protection at different heights;

[0045] At the same time, a plate groove 1201 is opened at an equal angle on the outer wall of the protective tube 1001, and a top baffle 1202 is movably installed inside the plate groove 1201. Half of the area of ​​the top baffle 1202 is located below the top baffle 1202 in the clockwise direction, thereby generating a stone blocking effect on the top of the protective tube 1001, thereby improving the protective effect;

[0046] As the embedded drill rod 5 is drilled, more stones are squeezed out to the top of the ground at the location where the hole needs to be drilled, and are located on the inner side of the cylinder formed by the combination of multiple push plates 1101. At this time, the cylinder 1004 is turned on to make the protective cylinder 1001 move upward. At this time, the push plate 1101 moves upward. At this time, the outer side of the stone is not restricted by the push plate 1101 and tilts outward. Then, the output end of the cylinder 1004 is controlled to move downward, so that the push plate 1101 is inserted into the stone. The electromagnet 1114 is energized to generate a repulsive force on the magnetic block 1113, pushing the bottom rod 1110 to move downward, and then the push plate 1101 is pulled by the first connecting rod 1112 to move toward the side away from the embedded drill rod 5, pushing the accumulated stones outward, and facilitating the subsequent discharge of stones.

[0047] When each push plate 1101 moves synchronously toward the side away from the embedded drill rod 5, a fan-shaped gap is generated between two adjacent push plates 1101, and the stones in the fan-shaped gap cannot be pushed out. At this time, the protective tube 1001 is pulled upward by the cylinder 1004. After the electromagnet 1114 is powered off, the push plate 1101 moves back under the elastic force of the first spring 1105, and then the third motor 1009 is turned on to rotate the gear 1008, and the gear 1008 is meshed with the toothed ring 1007 at the top of the protective tube 1001, thereby driving the protective tube 1001 to rotate a certain angle, and then repeating the above operation, the stones in the fan-shaped area can be pushed out, further facilitating the subsequent discharge of stones;

[0048] When the movable plate 1109 moves downward, the extrusion block 1210 moves downward along the surface of the pressure inclined surface 1209, thereby pushing the pressure block 1207 to move toward the side away from the protective tube 1001, and then pushing the side groove 1206 to move laterally, pushing the end plate 1203 to move upward through the third connecting rod 1217, and then pushing the movable ring 1205 to move upward, and pushing the top baffle 1202 to move a certain distance toward the embedded drill pipe 5 through each second connecting rod 1204, thereby increasing the shielding protection area of ​​the top of the protective tube 1001 and improving the protection effect;

[0049] When the end plate 1203 moves toward the protective tube 1001, it drives the fixed plate 1302 to move toward the clamping plate 1303, and the clamping plate 1303 contacts the surface of the friction ring 1301, so that the third spring 1306 is compressed. Under the elastic force of the third spring 1306, the clamping plate 1303 and the friction ring 1301 are pressed tightly, ensuring the stability between the protective tube 1001 and the limit sleeve 1002 when the stone is pushed out, thereby improving the working stability.
