[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3The utility model provides an embodiment: an underground mining equipment with dust reduction function, including a fixed column 1, the outer wall on the left side of the fixed column 1 is rotatably connected with a drill bit 2, the drill bit 2 is a prior art, and is a drill shield installed at the front end of an existing tunneling machine, the surface of the fixed column 1 is fixedly connected with a connecting ring 3, and a cavity is arranged inside the connecting ring 3, so that when water enters from the inside of the connecting pipe 4, it will enter the inside of the spray pipe 54 through the connecting ring 3 to the telescopic hose 55, and the surface of the fixed column 1 is fixedly connected with multiple groups of connecting pipes 4, and the connecting pipes 4 are far away from the fixed column 1. One end is fixedly connected to the outer wall of the connecting ring 3, a cavity is arranged inside the fixing column 1, water is stored inside the cavity, and a water pump is arranged inside the fixing column 1, which is a prior art. The water inside the fixing column 1 is controlled by the water pump to enter the inside of the connecting ring 3 from the connecting pipe 4. A rotating shaft 6 is penetrated and rotatably connected to the inner wall of the fixing column 1. The rotating shaft 6 is fixedly connected to the rotation center axis of the drill bit 2. The drill bit 2 is driven to rotate at high speed through the rotating shaft 6, so as to carry out excavation. This is a prior art, so that the rotating shaft 6 only drives the drill bit 2 to rotate, and the fixing column 1 will not rotate with it.

[0034] Reference Figure 2-Figure 4 The outer wall of the fixed column 1 is provided with an adjustment mechanism 5, and the adjustment mechanism 5 includes a moving ring 51, and the moving ring 51 is slidably connected to the surface of the fixed column 1. The inner side wall of the moving ring 51 is provided with a guide block, and the surface of the fixed column 1 is provided with a guide groove, so that the moving ring 51 can only move on the surface of the fixed column 1 and cannot be separated from its inner wall. The outer side wall of the moving ring 51 is hinged with a hinge rod 52, and one end of the hinge rod 52 away from the moving ring 51 is hinged to the outer wall of the spray pipe 54. When the moving ring 51 moves, it will drive the spray pipe 54 to rotate on the surface of the fixed plate 53 through the hinge rod 52 , thereby adjusting the angle of the spray pipe 54 and the nozzle 510, the bottom end of the outer wall of the telescopic hose 55 is fixedly connected to the surface of the movable ring 51, the outer wall of the connecting ring 3 is fixedly connected to multiple sets of fixed plates 53, the outer walls of the multiple sets of fixed plates 53 are rotatably connected to the spray pipe 54, and the bottom end of the outer wall of the spray pipe 54 is fixedly connected to the telescopic hose 55. The telescopic hose 55 is a prior art, so that when the spray pipe 54 rotates around the fixed plate 53, the telescopic hose 55 will shrink and stretch to prevent water from being discharged outward from the gap, and the inner wall of the movable ring 51 is elastically connected to the plug 57 through the limit spring 56.

[0035] Reference Figure 3-Figure 5One end of the limit spring 56 is fixedly connected to the surface of the plug block 57, and the other end of the limit spring 56 is fixedly connected to the top of the inner wall of the moving ring 51. The function of the limit spring 56 is to automatically reset the position of the plug block 57 stretched outward. The plug block 57 penetrates and is slidably connected to the inner wall of the top of the moving ring 51. A through hole is provided on the inner wall of the top of the fixed column 1. The bottom end of the outer wall of the plug block 57 is plugged into the inner wall of the through hole. The plug-in between the two fixes the moving ring 51 at multiple sliding positions on the surface of the fixed column 1.

[0036] Reference Figure 2 and Figure 4 The inner wall at the top of the spray pipe 54 is detachably mounted with a spray head 510 through a limit assembly 59, and the right side of the spray head 510 is slidably connected to the inner wall at the top of the spray pipe 54. The bottom end of the outer wall of the spray head 510 contacts the surface of the sealing ring 58, and the two are in contact, so that the gap between the inner walls of the spray pipe 54 and the spray head 510 is sealed by the sealing ring 58 to prevent water seepage at the connection. The inner wall at the top of the spray pipe 54 is provided with a sealing ring 58. The sealing ring 58 is a prior art, and its size matches the inner walls of the spray head 510 and the spray pipe 54, so as to fill and seal the connection between the two to avoid water seepage at the connection.

[0037] Reference Figure 4-Figure 5 The limiting assembly 59 includes a wedge block 592, which is elastically connected to the inner wall of the spray pipe 54 through a return spring 591, one end of the return spring 591 is fixedly connected to the surface of the wedge block 592, and the other end of the return spring 591 is fixedly connected to the inner wall of the spray pipe 54. The function of the return spring 591 is to automatically reset the position of the wedge block 592 after being squeezed and moved. The wedge block 592 penetrates and is slidably connected to the inner wall of the spray pipe 54. A slot is provided on the outer wall of the spray head 510, and the bottom end of the outer wall of the wedge block 592 is engaged with the inner wall of the slot. The engagement between the two fixes the position where the spray head 510 is installed on the inner wall of the spray pipe 54, thereby preventing the two from falling off during use.

[0038] Working principle: When a tunnel boring machine is used for drilling in underground mining, the rotating shaft 6 will drive the drill bit 2 to rotate at high speed to perform drilling operations. At this time, the plug block 57 can be pulled to move it upward on the inner wall of the moving ring 51, and the limit spring 56 can be elastically compressed. At this time, the moving ring 51 can be moved on the surface of the fixed column 1, so that the hinge rod 52 drives the spray pipe 54 to rotate around the fixed plate 53, so that the position of the spray head 510 is adjusted up and down, thereby adjusting the spraying range and adjusting the spraying range. After that, loosen the plug block 57 and it will be affected by the elastic action of the limit spring 56, restoring it to its original position, so as to be plugged into the through hole of the current position of the fixed column 1, thereby fixing the position of the movable ring 51 and the spray pipe 54 after rotation. At this time, the water pump inside the fixed column 1 can be started to allow the degradation water inside it to enter the interior of the connecting ring 3 from the connecting pipe 4, and enter the interior of the spray pipe 54 along the telescopic hose 55, and then be sprayed out from the nozzle 510, thereby degrading the dust raised by the drilling position of the drill bit 2.

[0039] When the nozzle 510 is used for a long time and its surface is clogged with dust and stones, the wedge block 592 can be pulled to disengage it from the clamping connection on both sides of the nozzle 510, so that the nozzle 510 can be removed from the top of the spray pipe 54, making it easier to replace and clean it.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
