[0006] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the driving unit includes a motor mounted on the top of a U-shaped block, the output end of the motor being connected to a fixing rod, and one end of the fixing rod extending into the interior of a first groove and connected to a first roller.

[0007] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the following part includes a strip rod inside the first slide groove, a second roller, a first spring and an insert rod are provided on the strip rod, the first spring is sleeved on the side wall of the insert rod, a fixing block is provided on the U-shaped block, an I-shaped block is provided on the fixing block, and the I-shaped block is sleeved on the side wall of the insert rod.

[0008] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the limiting part includes a second sliding groove on a fixed block, a first air bladder inside the second sliding groove, an air groove on an I-shaped block, a fixed ring inside the air groove, a second spring on the fixed ring, a second air bladder on the second spring, an insert block on the second air bladder, and a slot on the side wall of the insert rod.

[0009] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the extrusion part includes a screw on the side wall of a U-shaped block, the screw being rotatably connected to the U-shaped block, and an extrusion block being provided inside the second sliding groove, the extrusion block being sleeved on the side wall of the screw.

[0010] As a preferred embodiment of the intelligent cleaning brush head for coal mine train carriages of the present invention, the rotating part includes a first water pipe and a second water pipe on both sides of the water tank, and a blade is installed on the side wall of the screw.

[0011] As a preferred embodiment of the intelligent cleaning brush head for coal mine train carriages of the present invention, the reset part includes a reset groove at the end of the screw, and a coil spring is provided inside the reset groove.

[0012] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the flushing section includes a chamber inside a strip block, and water spray holes are provided on the side wall of the strip block.

[0013] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the sealing part includes a rectangular frame inside the cavity, a sealing plate connected to the bottom of the rectangular frame, and a through hole provided on the sealing plate.

[0014] As a preferred embodiment of the intelligent cleaning brush head for coal mine train cargo compartments of the present invention, the pressure stabilizing part includes a storage box on a strip block, and a floating block is provided inside the storage box, which is fixedly connected to a rectangular frame.

[0015] The beneficial effects of the intelligent cleaning brush head for coal mine train freight cars of the present invention:

[0016] 1. By setting up a clamping mechanism, an auxiliary mechanism and a washing mechanism, train cargo boxes of different thicknesses and sizes can be clamped. When the U-shaped block drives the strip block to move and spray water, the second roller at the current position can be restricted to prevent the reaction force of the strip block when spraying water from causing the first roller and the second roller to separate.

[0017] 2. When the water pump delivers clean water to the inside of the strip block, water can be stored first. When the water level rises to the float, the float can drive the sealing plate to rise. When the sealing plate drives the through hole to be horizontal with the spray hole, the clean water inside the chamber can be sprayed out through the spray hole to wash the coal slag on the inner wall of the train cargo box. This allows multiple spray holes to spray water simultaneously, ensuring that the inner wall of the train cargo box is cleaned synchronously. This avoids the situation where the lower spray holes spray water first when the water level rises, while the upper spray holes do not spray water, thus avoiding the waste of water resources. At the same time, when the strip block moves, it can drive the brush to scrub the coal slag in the train cargo box. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Reference Figures 1 to 11 This invention provides an intelligent cleaning brush head for coal mine train cargo boxes, which includes a clamping mechanism, an auxiliary mechanism, and a washing mechanism. It can clamp the cargo box according to the thickness of different train cargo box plates. During the clamping process, it does not affect the movement of the U-shaped block 10. When the U-shaped block 10 moves, it can clean the coal slag on the inner wall of the cargo box. During the washing of the inner wall of the cargo box, it can fix the relative position of the first roller 153 and the second roller 162, improve the stability of the U-shaped block 10 when moving, and also ensure the stability of the water pressure during washing.

[0035] Furthermore, the clamping mechanism can clamp cargo box panels of different thicknesses, facilitating the movement of the U-shaped block 10 on the cargo box and cleaning coal slag from the inner wall of the cargo box. The mechanism includes a U-shaped block 10, whose inner wall is provided with a first groove 11, a second groove 12, a storage slot 13, and a first sliding groove 14. The first groove 11 and the second groove 12 are directly opposite each other, the second groove 12 and the storage slot 13 are interconnected, and the storage slot 13 and the first sliding groove 14 are interconnected. The first groove 11 contains a driving part 15 for moving the U-shaped block 10. The first sliding groove 14 contains a follower part 16 suitable for different thicknesses of cargo box panels, with a limiting part 17 on the follower part 16 and a pressing part 18 on the U-shaped block 10.

[0036] Furthermore, the drive unit 15 includes a motor 151 mounted on the top of the U-shaped block 10. The motor 151 is controlled by a controller to achieve preliminary intelligence (the controller is a commonly used remote control device in the prior art, used by the staff to remotely control the motor 151 to rotate clockwise and counterclockwise). There are two motors 151. The output end of the motor 151 is connected to a fixing rod 152. One end of the fixing rod 152 extends into the interior of the first groove 11 and is connected to a first roller 153.

[0037] It should be noted that when the U-shaped block 10 is placed on the cargo box, the first roller 153 contacts the inner wall of the cargo box.

[0038] In use, the motor 151 can drive the fixed rod 152 to rotate, and the fixed rod 152 drives the first roller 153 to rotate.

[0039] Furthermore, the follower part 16 includes two strip rods 161 inside the first slide groove 14. Each strip rod 161 is equipped with a second roller 162, a first spring 163, and a plug rod 164. The first spring 163 is sleeved on the side wall of the plug rod 164. The two second rollers 162 are located between the two strip rods 161, and are directly opposite the first roller 163. One end of the rod 164 is inserted into the interior of the U-shaped block 10, and the rod 164 can move laterally on the U-shaped block 10. A fixing block 165 is provided on the U-shaped block 10. One end of the fixing block 165 extends to the outside of the U-shaped block 10, and the other end of the fixing block 165 is located inside the second groove 12. An I-shaped block 166 is provided on the fixing block 165. The I-shaped block 166 is sleeved on the side wall of the rod 164, and the I-shaped block 166 is fixedly installed inside the first sliding groove 14.

[0040] During use, depending on the thickness of the cargo box material, when the U-shaped block 10 is located on the cargo box material, the second roller 162 is squeezed by the cargo box. The second roller 162 can drive the strip rod 161 to move inside the first slide groove 14. The strip rod 161 drives the insert rod 164 to extend into the U-shaped block 10. At the same time, under the obstruction of the I-shaped block 166, the strip rod 161 drives the first spring 163 to retract. Through the arrangement of the first spring 163 and the strip rod 161, the first roller 153 and the second roller 162 are always in contact with the cargo box material. When the motor 151 is started, the motor 151 can drive the first roller 153 to roll on the inner wall of the cargo box, thereby allowing the U-shaped block 10 to move on the cargo box, which facilitates the cleaning of coal slag on the inner wall of the cargo box.

[0041] Furthermore, the limiting part 17 includes a second sliding groove 171 on the fixing block 165, a first airbag 172 is provided inside the second sliding groove 171, an air groove 173 is provided on the I-shaped block 166, the air groove 173 communicates with the second sliding groove 171, a fixing ring 174 is provided inside the air groove 173, a second spring 175 is provided on the fixing ring 174, a second airbag 176 is provided on the second spring 175, an insert block 177 is provided on the second airbag 176, and a slot 178 is provided on the side wall of the insert rod 164. There are multiple slots 178, which are evenly distributed on the side wall of the insert rod 164, and the insert rod 164 is adapted to the slot 178.

[0042] When in use, when the first airbag 172 is compressed, the gas inside the first airbag 172 enters the interior of the second airbag 176 along the air groove 173, causing the second airbag 176 to extend. The second airbag 176 drives the second spring 175 to extend. At the same time, the second airbag 176 drives the insert block 177 to insert into the interior of the slot 178, which can restrict the position of the insert rod 164 and prevent the first roller 153 and the second roller 162 from breaking contact with the cargo box plate due to external forces when the U-shaped block 10 moves, thus affecting the normal movement of the U-shaped block 10.

[0043] Furthermore, the extrusion section 18 includes a screw 181 on the side wall of the U-shaped block 10, the screw 181 being rotatably connected to the U-shaped block 10, and an extrusion block 182 being provided inside the second slide groove 171, the extrusion block 182 being sleeved on the side wall of the screw 181.

[0044] When in use, when the threaded rod rotates, the extrusion block 182 can move inside the second slide groove 171, and the extrusion block 182 can extrude the first airbag 172 when it moves.

[0045] Furthermore, the auxiliary mechanism can restrict the position of the second roller 162 when washing the train car, so as to avoid the force generated by the water washing from affecting the stability of the movement of the U-shaped block 10. This includes a fixed seat 20 on the side wall of the U-shaped block 10, a water tank 21 on the fixed seat 20, a rotating part 22 inside the water tank 21, and a reset part 23 on the rotating part 22.

[0046] Furthermore, the rotating part 22 includes a first water pipe 221 and a second water pipe 222 on both sides of the water tank 21, and a blade 223 is installed on the side wall of the screw 181.

[0047] In use, a water pump can deliver clean water to the inside of the water tank 21 through the first water pipe 221. During the flow of clean water, the paddle 223 can be rotated. The paddle 223 can drive the screw 181 to rotate. When the screw 181 rotates, it can drive the extrusion block 182 to move inside the second slide groove 171, so that the extrusion block 182 pushes the first airbag 172 to contract.

[0048] Furthermore, the reset part 23 includes a reset groove 231 at the end of the screw 181. A coil spring 232 is provided inside the reset groove 231. One end of the coil spring 232 is connected to the inner wall of the water tank 21, and the other end of the coil spring 232 is connected to the inner wall of the reset groove 231.

[0049] When in use, when the screw 181 rotates, it can cause the coil spring 232 to retract. When the clean water in the water tank 21 stops being transported, the coil spring 232 can cause the screw 181 to rotate back to its initial state.

[0050] Furthermore, the washing mechanism can simultaneously rinse and wash the inner wall of the train freight car while ensuring water pressure. It includes a base 30 on the U-shaped block 10, a strip block 31 on the base 30, a brush 32 on the strip block 31, a rinsing part 33 on the strip block 31, a sealing part 34 on the rinsing part 33, and a pressure stabilizing part 35 on the sealing part 34.

[0051] When in use, as the U-shaped block 10 moves, the U-shaped block 10 can drive the brush 32 on the strip block 31 to scrub the inner wall of the train freight car.

[0052] Furthermore, the rinsing section 33 includes a chamber 331 inside the strip block 31, and a water spray hole 332 is provided on the side wall of the strip block 31, which communicates with the chamber 331.

[0053] When in use, when clean water is injected into the chamber 331, the clean water can be sprayed out from the spray nozzle 332, and the sprayed water can wash away the coal slag on the inner wall of the train freight car.

[0054] Furthermore, the sealing part 34 includes a rectangular frame 341 inside the chamber 331. A sealing plate 342 is connected to the bottom of the rectangular frame 341. There are two sealing plates 342, which are slidably connected to the inner wall of the chamber 331 respectively. A through hole 343 is provided on the sealing plate 342.

[0055] It should be noted that when there is no clean water inside the chamber 331, the sealing plate 342 is located on the bottom surface inside the chamber 331. The sealing plate 342 can seal the water spray hole 332, allowing water to be stored inside the chamber 331. When the through hole 343 and the water spray hole 332 are in a horizontal position, the clean water inside the chamber 331 can be sprayed out through the through hole 343 and the water spray hole 332.

[0056] Furthermore, the voltage stabilizing unit 35 includes a storage box 351 on the strip block 31, and a float 352 is provided inside the storage box 351. The float 352 is fixedly connected to the rectangular frame 341.

[0057] It should be noted that as the amount of clean water inside chamber 331 gradually increases, when the water level rises to the position of float 352, the subsequent rise in water level can drive float 352 to rise, and when float 352 rises, it can drive sealing plate 342 to rise together.

[0058] Working principle:

[0059] To meet water transport needs, the coal slag on the inner walls of the train cargo box needs to be cleaned first to prevent damage caused by friction between the waterproof cloth and the coal slag during transport. Workers first install U-shaped blocks 10 on the top of the train cargo box panels. The arrangement of strip rods 161, first sliding grooves 14, second rollers 162, first springs 163, and I-shaped blocks 166 allows for adjustment based on the thickness of the cargo box panels, ensuring that the first rollers 153 and 162 are in contact with the sides of the cargo box panels. Workers then start motor 151, which drives the first rollers 153 to rotate, moving the U-shaped blocks 10 across the train cargo box. Simultaneously, the water pump is started, and clean water enters the water tank 21 through the first water pipe 221. The water flow drives the paddle inside the water tank 21. When blade 223 rotates, it drives screw 181 to rotate. Screw 181 drives coil spring 232 to retract. While screw 181 rotates, it also drives extrusion block 182 to move inside the second slide groove 171. When extrusion block 182 moves, it extrudes first airbag 172. The gas inside first airbag 172 is compressed and enters the inside of second airbag 176 through air groove 173. Second airbag 176 extends, driving second spring 175 to extend, and at the same time, it drives insertion block 177 to insert into slot 178, restricting the position of insertion rod 164, preventing the position of second roller 162 from changing, and ensuring the stability of U-shaped block 10 movement. U-shaped block 10 drives strip block 31 to move, and strip block 31 drives brush 32 to scrub the inner wall of cargo box.

[0060] To ensure that multiple water spray holes 332 spray water simultaneously, after passing through the paddle 223, the clean water flows into the interior of the chamber 331 through the second water pipe 222, causing the water level inside the chamber 331 to gradually rise. When the water level rises to the float 352, it can drive the float 352 to rise together. The float 352 drives the rectangular frame 341 to rise, and the rectangular frame 341 drives the sealing plate 342 to rise. When the float 352 is at the highest point of the storage box 351, the sealing plate 342 drives the through hole 343 to be horizontal with the water spray hole 332. The clean water inside the chamber 331 can be sprayed out from the through hole 343 and the water spray hole 332 to wash the coal slag on the inner wall of the train cargo box. At the same time, the motor 151 drives the U-shaped block 10 to move stably on the train cargo box, washing the inner wall of the cargo box while rinsing with water.

[0061] After the current board material is cleaned, the workers stop the water pump and motor 151. When the clean water inside the water tank 21 stops flowing, the coil spring 232 drives the screw 181 back to its initial state, causing the squeezing block 182 to move in the opposite direction and release the squeezing of the first airbag 172. At the same time, the second spring 175 can drive the second airbag 176 to contract. The second airbag 176 drives the insert block 177 to disengage from the inside of the slot 178, releasing the restriction on the insert rod 164. At this time, the workers can remove the U-shaped block 10 from the truck board material and install the U-shaped block 10 on other truck board materials for cleaning.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
