Description

Technical Field

[0001] The utility model relates to the technical field of coal mine belt conveyors, and specifically relates to a surface coal slime cleaning structure for a coal mine belt conveyor. Background Technique

[0002] A coal mine belt conveyor is a transportation device widely used in coal mine production, and it is mainly used for coal transportation underground or on the ground. The cleaning of the coal slime on the surface of the belt of a coal mine belt conveyor is an important maintenance link, which not only relates to the operation efficiency of the conveyor, but also involves the service life and safety of the equipment. In order not to let the coal mine leak outwards during transportation, the belts of some coal mine belt conveyors are recessed in the middle, and the bottom of the belt is supported by multiple inclined rollers, and the coal mine is gathered in the middle for transportation. When cleaning the belt, some people stand on the frame manually, use cleaning tools to contact different positions on the surface of the belt, and clean by scraping when the belt rotates. First of all, this method is relatively dangerous, and the thrust generated by friction may cause the cleaning personnel to fall onto the belt and cause safety accidents. Moreover, the sundries generated by cleaning leak out and fall to both sides and the end of the belt, which requires subsequent cleaning, consuming manpower and being inconvenient to use.

[0037] In this embodiment, the two hydraulic rods 3 121 are started to drive the push rod 12 to move to the bottom of the belt body 22, and the middle part of the belt body 22 is supported by the push rod 12. The inclined plate 13 can guide the debris cleaned by the cleaning roller 2 142 to the inside of the limiting shell 10. The two hydraulic rods 4 144 are started to move the two cleaning rollers 2 142 to the top of the belt body 22 for cleaning. The motor 2 151 is started to drive the adjacent card seat 14 to rotate, so that the two card seats 14 and the connecting shell 141 are driven to rotate synchronously through the connection of the cleaning roller 2 142. At the same time, the two accommodating shells 143 drive the cleaning roller 2 142 to rotate around the connecting shell 141. In the process, the two cleaning rollers 2 142 are driven to rotate by themselves through the transmission of the outer gear ring 154 and the gear 153, and the top of the belt body 22 is scraped and cleaned alternately by the two cleaning rollers 2 142, and the debris is moved to the top of the inclined plate 13.

[0038] like Figure 4 As shown, in the present embodiment, two protective shells 113 are symmetrically fixedly connected to the top of the limit frame 11, a hydraulic rod 111 is fixedly connected to the inner wall of the protective shell 113, a cleaning roller 112 is rotatably connected between the output ends of the two hydraulic rods 111, a motor 115 is fixedly connected to the output end of one of the hydraulic rods 111, the output end of the motor 115 is fixedly connected to the adjacent end of the cleaning roller 112, hydraulic rods 114 are rotatably connected to both outer side walls of the limit shell 10, and the output end of the hydraulic rod 114 is rotatably connected to the limit frame 11.

Starting the two second hydraulic rods 114 drives the limiting frame 11 to rotate, thereby pouring the debris inside the limiting frame 11 into the limiting shell 10 for collection.

[0040] Embodiment 2

[0041] Based on Embodiment 1, in order to be able to drive the limiting shell 10 to automatically and quantitatively traverse horizontally, thereby facilitating the cleaning of different positions of the belt body 22.

[0042] As Figures 1-5 shown, in this embodiment, a plurality of first rollers 102 are rotatably connected to the bottom of the limiting shell 10. A trap door 103 is rotatably connected to the rear side of the limiting shell 10 through a hinge. The regulation module 16 includes a rectangular block 161. The rectangular block 161 is slidably connected to the top of the limiting shell 10. Two sleeves 162 are fixedly connected to one side of the rectangular block 161. A ferrule 164 is slidably connected inside the adjacent sleeve 162. A spring 163 is fixedly connected between the ferrule 164 and the rectangular block 161. A plurality of balls 165 are rotatably connected to the inner wall of the ferrule 164. A fixed frame 166 is fixedly connected to the front side of the limiting shell 10. Two connecting arms 167 are rotatably connected to the top of the fixed frame 166. A driving frame 168 is arranged above the fixed frame 166. Both connecting arms 167 are rotatably connected to the driving frame 168. A plurality of second rollers 1681 are rotatably connected to the front side of the driving frame 168 at equal intervals. A third motor 169 is fixedly connected to the bottom of the fixed frame 166. The output end of the third motor 169 penetrates the fixed frame 166 and is fixedly connected to the adjacent connecting arm 167.

[0043] In the specific implementation, the setting of the roller 102 facilitates the overall lateral movement of the limit shell 10, and the setting of the trap door 103 facilitates the removal of the debris collected by the limit shell 10. The rectangular block 161 cooperates with the two sleeves 162 to perform sliding limit in the vertical direction, and the limit shell 10 is pushed to one side of the conveyor body 20 as a whole, and the clamping sleeve 164 is placed just above the support rod 21, and then the clamping sleeve 164 is moved down to clamp it with the top of the support rod 21 to complete the initial limit. At this time, the limit shell 10 can move horizontally to clean different positions of the belt body 22, and the ball 165 is convenient for reducing the clamping sleeve 164 and the support rod. The sliding friction between the rods 21 makes the movement smoother, the sleeve 162 limits the lateral sliding of the sleeve 164, the spring 163 can drive the sleeve 164 to move and reset, and adjust the position of the limit shell 10, start the motor three 169 to drive the adjacent connecting arms 167 to rotate reciprocatingly, and through the connection of the driving frame 168, the two connecting arms 167 rotate synchronously, the driving frame 168 shakes back and forth, and during the process the driving frame 168 always remains parallel to the rectangular block 161, and the fence of the support rod 21 is alternately moved by multiple rollers 2 1681, thereby driving the limit shell 10 to move horizontally as a whole to adjust the position.
