Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically a dust suppression and drainage device for coal mine tunneling. Background Technology

[0002] A large amount of dust is generated during coal mine tunneling operations. Dust suppression and drainage devices are required to control dust at the construction site. However, in the existing technology, it is difficult to effectively adjust the dust suppression range according to the site conditions when using dust suppression and drainage devices, which makes the flexibility of use less than ideal.

[0003] For example, patent publication number CN212803318U is specifically a dust suppression device for coal mine tunneling. This dust suppression device aims to collect dust and improve dust suppression efficiency and quality. However, this dust suppression and drainage device has the problem that it is difficult to effectively adjust the dust suppression range according to the site conditions during dust suppression operations, resulting in insufficient flexibility in its use.

[0004] For example, patent publication number CN219139115U describes a dust suppression device for coal mine tunneling. When the end of the locking block slides out of the locking groove, it can pull the protective net. The protective net, when pulled, can slide against the inner wall of the spraying device. When the protective net slides out of the spraying device, it can be disassembled. A threaded rod can be rotated, and this rotation can be achieved through an adjusting groove. The rotation of the threaded rod can drive the threaded sleeve to slide, and the sliding of the threaded sleeve can drive the guide block to slide within the guide groove. When one end of the threaded sleeve slides into the sliding groove, the protective cover can be fixed, facilitating the protection of the spray holes. However, this dust suppression and drainage device suffers from the problem that it is difficult to effectively adjust the dust suppression range according to the site conditions during dust suppression operations, resulting in insufficient flexibility in its use. Summary of the Invention

[0018] 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.

[0019] Please see Figure 1-3The present invention provides a technical solution: a dust suppression and drainage device for coal mine tunneling, including a movable base 1, a support frame 3 fixedly connected to the top of the movable base 1, a water tank 4 inside the support frame 3, and a spray dust suppression mechanism 2 on the top of the support frame 3. The swing range can be effectively adjusted by the spray dust suppression mechanism 2, so that the spray range can be adjusted according to the actual situation on site, effectively improving the flexibility of use.

[0020] The dust suppression spray mechanism 2 includes a rocker arm 201. One end of the rocker arm 201 is rotatably connected to a support frame 3, and the other end of the rocker arm 201 is fixedly connected to a mounting base 202. This allows the rocker arm 201 to rotate, causing the mounting base 202 to swing back and forth, thus expanding the spray range. A rotating base 203 is rotatably connected to the top of the mounting base 202. Multiple spray heads 204 are provided on the side surface of the rotating base 203. A rotary motor 206 is driven to one side of the rotating base 203. The transmission structure between the rotary motor 206 and the rotating base 203 includes two transmission gears. The two transmission gears are fixedly connected to the rotating base 203 and the output shaft end of the rotary motor 206, respectively. The rotary motor 206 can drive the rotating base 203 to rotate. The rotation of the spray head 204 effectively increases the spray radius, spray range, and spray effect. A rotary joint 205 is located at the bottom of the rotating base 203. A water pump is located at one end of the water tank 4, with an inlet pipe connected to the pump. The inlet pipe is connected to the rotary joint 205, allowing the pump to supply water to the rotating base 203 while it is rotating. A swing disk 207 is located on one side of the rocker arm 201, with a swing motor 208 connected to its bottom. The transmission structure between the swing motor 208 and the swing disk 207 includes two bevel gears, which are fixedly connected to the output shafts of the swing disk 207 and the swing motor 208, respectively, enabling the swing motor 208 to drive the swing disk 207 to rotate. A telescopic rod 209 is provided between the swing turntable 207 and the rocker arm 201. One end of the telescopic rod 209 is rotatably connected to the eccentric part of the swing turntable 207, and the other end is rotatably connected to the end of the rocker arm 201, so that the swing turntable 207 can rotate using the telescopic rod 209. An adjusting nut 210 is fixedly connected to the telescopic rod 209, and an adjusting bolt 211 is threaded inside the adjusting nut 210. The telescopic rod 209 has multiple adjusting holes 212. The end of the adjusting bolt 211 passes through the adjusting nut 210 and extends into the telescopic rod 209, and the adjusting bolt 211 matches the adjusting hole 212. The adjusting bolt 211 can be inserted into different adjusting holes 212 to adjust the telescopic rod 209. Locking is achieved by pulling the telescopic rod 209 to extend or retract it, then tightening the adjusting bolt 211 into the adjusting hole 212 for fixation, thus changing the length of the telescopic rod 209. The swing motor 208 then drives the swing turntable 207 to rotate. The swing turntable 207 uses the telescopic rod 209 to drive the rocker arm 201 to swing back and forth. The rocker arm 201 swings, causing the mounting base 202 to swing. During the swing of the mounting base 202, the rotary motor 206 drives multiple spray heads 204 to rotate, expanding the spray radius. Simultaneously, by changing the length of the telescopic rod 209, the swing amplitude can be adjusted, allowing for adjustment of the spray range according to the actual situation on site, effectively improving the flexibility of use.

[0021] Please see Figure 1and Figure 4 The mobile base 1 has multiple casters at its bottom. A push handle 5 is fixedly connected to one end of the mobile base 1. A stabilizing mechanism 6 is provided on one side of the top of the mobile base 1. The stabilizing mechanism 6 includes a stabilizing nut 601, which is fixedly mounted on the mobile base 1. A stabilizing screw 602 is threaded inside the stabilizing nut 601. A rotating handle 603 is fixedly connected to the top of the stabilizing screw 602, and a stabilizing seat 604 is fixedly connected to the bottom of the stabilizing screw 602. The entire unit can be easily moved by the multiple casters. When the rotating handle 603 is rotated, the rotating handle 603 drives the stabilizing screw 602 to rotate. The rotation of the stabilizing screw 602, in conjunction with the stabilizing nut 601, drives the stabilizing seat 604 to move down to the ground, thus providing a good stabilizing effect.

[0022] During operation, the telescopic rod 209 is pulled to extend or retract, and then the adjusting bolt 211 is tightened and screwed into the adjusting hole 212 for fixation, changing the length of the telescopic rod 209. Then, the swing motor 208 drives the swing turntable 207 to rotate. The swing turntable 207 uses the telescopic rod 209 to drive the rocker arm 201 to swing back and forth. The swing of the rocker arm 201 drives the mounting base 202 to swing. During the swing of the mounting base 202, the rotary motor 206 drives multiple spray heads 204 to rotate, expanding the spray radius. At the same time, the swing amplitude is adjusted by changing the length of the telescopic rod 209, so that the spray range can be adjusted according to the actual situation on site, effectively improving the flexibility of use.
