The blade head 101 is rotatably connected to the support frame 104, and the support frame 104 is fixed to the loader by the fixing frame 103. It also includes a dust removal and cleaning assembly 200; the dust removal and cleaning assembly 200 includes a rotating frame 201 and a spray nozzle. The system includes a mist nozzle 202, a delivery pipe 203, a water storage tank 205, a rotating gear 207, a water supply pipe 208, a cleaning nozzle 209, and a drive pump 211. The rotating frame 201 is rotatably connected to the top of the fixed frame 103. The tilt angle of the rotating frame 201 can be adjusted by rotating it. Multiple delivery pipes 203 are fixed on the rotating frame 201. The delivery pipes 203 are connected to the water storage tank 205 via the water supply pipe 208. The water storage tank 205 stores water for dust removal. The water storage tank 205 is fixed to the fixed frame 103. A drive pump 211 is fixed inside the water tank 205. The drive pump 211 is connected to the water supply pipe 208. The drive pump 211 drives the water in the water tank 205 to enter the delivery pipe 203 through the water supply pipe 208. A spray head 202 is fixed on the side wall of the delivery pipe 203. The spray head 202 can spray water into the air in the form of water mist. The water mist can moisten dust particles floating in the air and make them settle quickly. The delivery pipe 203 is rotatably connected to the rotating frame 201. Interlocking parts are fixed on the delivery pipe 203. The rotating gear 207 is driven by a motor, which is fixed on the rotating frame 201. A cleaning nozzle 209 is fixed on the other side of the conveying pipe 203. After each use of the shovel head 101, the rotating frame 201 is rotated to a state parallel to the shovel head 101, and the cleaning nozzle 209 is rotated to a position facing the inside of the shovel head 101 under the drive of the motor. The water in the water storage tank 205 is driven by the drive pump 211 to spray water from the cleaning nozzle 209 onto the shovel head 101 to clean the coal debris attached to the shovel head 101.

[0021] Preferably, the rotating frame 201 is a rectangular frame, and a handle 204 is fixed to the top of the rotating frame 201. The rotating frame 201 can be manually rotated by pulling the handle 204. The rotating frame 201 and the fixed frame 103 are connected by a damped rotating shaft, so that the rotating frame 201 can stop at a specified angle. The handle 204 is wrapped with an anti-slip rubber sleeve to increase the friction during operation and prevent the hand from slipping.

[0022] Preferably, the water storage tank 205 is fixed on the side wall of the principle shovel head 101 of the fixing frame 103, and a water injection pipe is fixed on the top of the water storage tank 205. Water is injected into the water storage tank 205 through the water storage pipe. A sealing cap is provided on the water injection pipe to prevent dust from entering the interior of the water storage tank 205 and to ensure water quality.

[0023] Preferably, two drive gears 206 are fixed on the side walls of the fixed frame 103 and the rotating frame 201. One drive gear 206 is fixed on the rotating shaft of the motor, which is located inside the fixed frame 103. The other drive gear 206 is fixed on the rotating shaft of the rotating frame 201. The rotating frame 201 is driven to rotate by the motor, thereby adjusting the tilt angle of the rotating frame 201. When the forklift is working, the rotating frame 201 tilts upward so that the water mist sprayed from the spray nozzle can be dispersed into the air, thereby wetting the dust particles generated at the shovel head 101. By driving the rotating frame 201 to rotate by the motor, the tilt angle of the rotating frame 201 can be easily adjusted according to the area of ​​dust, so that the water mist sprayed from the spray nozzle can be directly sprayed onto the area of ​​dust.

[0024] Preferably, the conveying pipe 203 is a cylindrical rod, and the inside of the conveying pipe 203 is divided into two chambers. The two chambers are respectively connected to the spray nozzle and the cleaning nozzle 209. The diameter of the chamber connected to the cleaning nozzle 209 is larger than that of the chamber connected to the spray nozzle, so that the water pressure sprayed from the cleaning nozzle 209 can wash away the coal sludge adhering to the shovel head 101.

[0025] Preferably, a control valve 212 is fixed at the bottom of the delivery pipe 203. The control valve 212 is a solenoid valve. The control valve 212 controls which chamber the water entering the delivery pipe 203 flows into. The control valve 212 can precisely adjust the water flow direction to ensure that the water flow can accurately enter the corresponding chamber under different working conditions. When spraying to suppress dust is required, the control valve 212 will guide the water flow into the chamber connected to the spray nozzle, thereby effectively suppressing dust. When cleaning the shovel head 101, the control valve 212 will switch the water flow to the chamber connected to the cleaning nozzle 209 to ensure that the high-pressure water flow can thoroughly remove the residue inside the shovel head 101.

[0026] Preferably, the rotating frame 201 is fixed with 6 to 8 conveying pipes 203, and each conveying pipe 203 is fixed with 4 to 6 spray nozzles. The spray nozzles are disc-shaped and have multiple nozzles. The spray nozzles are detachably fixed to the conveying pipes 203 by threaded connection, so that the spray nozzles can be easily disassembled and replaced when the nozzles are blocked.

[0027] Preferably, the water mist particles sprayed from the spray nozzle have a diameter of 50μm to 150μm, which can effectively adsorb dust particles in the air and achieve a good dust reduction effect. At the same time, the water mist in this size range can be distributed relatively evenly during the spraying process, ensuring a wide coverage area and preventing rapid settling due to excessively large particles, or failure to effectively capture dust due to excessively small particles.

[0028] Preferably, the water supply pipe 208 is a rubber hose, which is fixed to the rotating frame 201 by a threaded pipe. The rotating frame 201 is provided with a water pipe that communicates with the delivery pipe 203, so that water is delivered to each delivery pipe 203 through the water pipe.

[0029] Preferably, the cleaning nozzle 209 is a vortex booster nozzle, which can increase the water flow speed and impact force, thereby enhancing the cleaning effect. The cleaning nozzle 209 is made of a high-performance alloy that is corrosion-resistant and wear-resistant, ensuring that it can maintain a long service life even under harsh working conditions.

[0030] Preferably, the side wall of the shovel head 101 is provided with a plurality of drainage holes 106. The drainage holes 106 can quickly drain the water inside the shovel head 101 when the cleaning nozzle 209 washes the shovel head 101, so as to avoid the shovel head 101 from rusting or coal sludge from adhering again due to water residue.

[0031] Preferably, a connecting seat 105 is fixed to the outside of the shovel head 101, and the hydraulic rod 102 and the support frame 104 are rotatably connected to the shovel head 101 through the connecting seat 105.

[0032] Preferably, the fixing frame 103 is a rectangular metal plate with multiple threaded holes. The fixing frame 103 is fixed to the loader head by bolts, thereby fixing the shovel head 101 to the loader head. This makes it convenient to replace the shovel head 101 with a suitable size according to usage requirements. The fixing frame 103 is made of high-strength alloy steel, which can adapt to the complex working environment of mine roadways.

[0033] Preferably, the fixed nozzle of the spray head is conical, which can guide the water flow to spray out at a specific angle, thereby improving the diffusion range and coverage effect of the water mist.

[0034] Preferably, the support frame 104 is bolted to the side wall of the fixed frame 103. The support frame 104 is made of high-strength steel to ensure sufficient stability and load-bearing capacity during use. The surface of the support frame 104 is treated with rust prevention to effectively resist moisture and corrosive substances in the mining environment, thus extending its service life.

[0035] Preferably, the shovel head 101 is made of high-strength wear-resistant material and has a special arc-shaped structure inside, which can effectively reduce the residue of coal dust in the shovel head 101. The edge of the shovel head 101 is thickened to enhance its durability during bulldozing. At the same time, the edge is also equipped with replaceable wear-resistant strips, which facilitates partial replacement when wear is severe, thereby reducing maintenance costs.

[0036] In practical use, a telescopic bulldozer blade for a mine roadway repair machine according to an embodiment of this application is as follows: The drive gear 206 on the motor shaft meshes with the drive gear 206 on the rotating frame 201 shaft, driving the rotating frame 201 to rotate to a preset upward angle, allowing the spray head 202 to accurately cover the dust diffusion area of ​​the subsequent bulldozing operation. The hydraulic system on the loader is activated, driving the shovel head 101 to rotate around the support frame 104 via the hydraulic rod 102, adjusting the working angle of the shovel head 101. With the loader's forward propulsion, the shovel head 101 pushes and repairs the slag, gravel, etc. in the mine roadway. The drive pump 211 in the water storage tank 205 is activated, pressurizing the clean water in the water storage tank 205 and then delivering it to each delivery pipe 203 through the water delivery pipe 208. The water flows through the delivery pipe 203 into the spray nozzle. The mist nozzle 202 sprays water mist particles of 50μm-150μm into the air of the work area through multiple nozzles on the spray head. The water mist fully contacts and wets the scattered dust particles, causing them to settle rapidly due to gravity. During operation, if the dust-covered area is found to have shifted, the tilt angle of the rotating frame 201 can be adjusted manually or electrically: for manual adjustment, pull the handle 204 to rotate the rotating frame 201 to the appropriate angle, and the damping shaft ensures that it remains stable in the adjusted position; for electric adjustment, the motor drives the gear 206 to rotate the rotating frame 201, so that the water mist sprayed by the spray head 202 accurately covers the new dust-covered area. After the bulldozing operation is completed, stop the hydraulic system operation and... The shovel head 101 is reset to a horizontal position; the rotating frame 201 is adjusted manually or electrically to rotate it parallel to the shovel head 101; the motor driving the conveying pipe 203 is started, causing the conveying pipe 203 to rotate, so that the cleaning nozzle 209 on the other side of the conveying pipe 203 rotates to face the inside of the shovel head 101; the solenoid control valve 212 is switched to the "shovel head 101 cleaning" position, allowing water to flow into the chamber in the conveying pipe 203 that is connected to the cleaning nozzle 209; the drive pump 211 is started again, and the clean water in the water tank 205 is pressurized and then enters the cleaning nozzle 209 through the water supply pipe 208 and the conveying pipe 203; because the cleaning nozzle 209 adopts a vortex pressurization structure, the water flows through the cleaning nozzle 209 at high pressure. Water is sprayed into the shovel head 101 in the form of a jet; the high-pressure water jet washes away coal dust, coal sludge and other residues adhering to the shovel head 101; during the cleaning process, the shovel head 101 can be slightly rotated by the hydraulic rod 102 to adjust the flushing angle inside the shovel head 101 to ensure that there are no dead corners in the cleaning process. The sewage generated during the cleaning process is quickly discharged through multiple drainage holes 106 opened on the side wall of the shovel head 101 to avoid water accumulation and rusting of the shovel head 101 or secondary adhesion of coal sludge. After the shovel head 101 is cleaned, the drive pump 211 and all motors are turned off to stop the water flow; the electromagnetic control valve 212 is reset to the initial state. If the water in the water storage tank 205 is insufficient, clean water is added to the water storage tank 205 through the water inlet 210.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
