Description

Technical Field

[0001] This utility model relates to the field of coal mine conveyor technology, and more specifically, to a debris blocking device for a coal mine belt conveyor. Background Technology

[0002] Coal mine belt conveyors are widely used conveying equipment in the coal mining industry, mainly for the continuous transport of coal. Because coal mining requires the handling of large quantities of materials, belt conveyors have become an efficient, economical, and stable transportation method. The working principle of a belt conveyor is that a drive unit drives a drive drum to rotate, and the rotation of the drum drives the belt to move, thereby transporting coal or other materials along the track of the conveyor belt.

[0003] During coal mining, a lot of equipment is used. During the use or maintenance of the equipment, some iron parts inevitably fall off. The building structure in the mine may leave behind long materials such as steel bars, steel strips or wood that get mixed into the coal mine. When these debris enter the coal bunker, it may cause a coal bunker blockage accident. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a debris blocking device for a coal mine belt conveyor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a debris blocking device for a coal mine belt conveyor, comprising a main body of a transmission mechanism, wherein a blocking component, a cleaning component, and an adsorption component are sequentially installed on the top of the main body of the transmission mechanism from left to right. The blocking component includes a fixed frame fixedly connected to the outside of the main body of the transmission mechanism, an mounting block fixedly connected to the front of the inner wall of the fixed frame, a long strip plate movably connected to the mounting block via a fixed shaft, a blocking strip fixedly connected to the bottom of the long strip plate, and a horizontal strip fixedly connected to the bottom of the blocking strip. The cleaning component includes a support plate fixedly connected to the top of the main body of the transmission mechanism, a fixed frame fixedly connected to the top of the support plate, a translation motor fixedly connected to the front of the fixed frame, a screw fixedly connected to the output shaft of the translation motor, a moving plate threaded onto the outside of the screw, a fixed block fixedly connected to the top of the moving plate, a connecting block fixedly connected to the top right side of the fixed block, and a scraper fixedly connected to the right side of the connecting block.

[0006] As a preferred embodiment of this utility model, the adsorption assembly includes a support plate, a rotary motor is fixedly connected to the front of the support plate, a rotary rod is fixedly connected to the output shaft of the rotary motor, a support rod is fixedly connected to the middle of the outer side of the rotary rod, and a magnetic frame is fixedly connected to the outer side of the support rod.

[0007] As a preferred embodiment of this utility model, a cylindrical frame is fixedly connected to both the front and back of the magnetic frame, and the cylindrical frame is made of stainless steel.

[0008] As a preferred embodiment of this utility model, a cylinder is fixedly connected to the top of the inner wall of the fixing frame, and a connecting component is installed on the back of the piston rod of the cylinder. The end of the connecting component away from the cylinder is connected to the back of the top of the long strip plate.

[0009] As a preferred embodiment of this utility model, a baffle is fixedly connected to the top of the fixed frame, and a rectangular groove is provided on the side of the baffle, which is slidably connected to the connecting block.

[0010] As a preferred embodiment of this utility model, a positioning rod is fixedly connected to the inner side of the fixed frame, and the positioning rod is slidably sleeved with the moving plate.

[0011] As a preferred technical solution of this utility model, a sliding groove is provided in the middle of the top of the fixed frame, and the sliding groove is slidably connected to the fixed block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by providing a blocking component, and the cooperation of the blocking strip and the horizontal strip, can block long debris. When a long debris is blocked by the blocking strip, the cylinder is activated to drive the piston rod to retract, thereby the connecting component drives one end of the back of the long strip to rotate a certain angle around the fixed axis inside the mounting block, so that the horizontal strip is tilted with the back height higher than the front height. Then the long debris slides down the surface of the horizontal strip to the front, thus removing the debris.

[0014] 2. This utility model is equipped with a cleaning component and an adsorption component. A rotary motor drives a rotating rod to rotate, which in turn drives the support rod to rotate the magnetic frame counterclockwise. The magnetic frame can adsorb ferrous debris, and the fixed frame can intercept the debris adsorbed by the magnetic frame. Activating a translation motor drives a screw to rotate, and a moving plate drives the fixed block to move back and forth. As a result, the scraper can scrape the ferrous debris intercepted on the top right side of the fixed frame to the front or back, preventing ferrous debris and long debris from entering the coal bunker and causing coal bunker blockage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a debris blocking device for a coal mine belt conveyor, including a transmission mechanism body 1. From left to right, a blocking component 2, a cleaning component 3, and an adsorption component 4 are sequentially installed on the top of the transmission mechanism body 1. The blocking component 2 includes a fixing frame 201 fixedly connected to the outside of the transmission mechanism body 1. An installation block 202 is fixedly connected to the front of the inner wall of the fixing frame 201. A long strip plate 203 is movably connected to the installation block 202 via a fixing shaft. A blocking strip 204 is fixedly connected to the bottom of the long strip plate 203. A horizontal strip 205 is fixedly connected to the bottom of the blocking strip 204. The cleaning component 3 includes a fixed connection... A support plate 301 is located on the top of the main body 1 of the transmission mechanism. A fixed frame 302 is fixedly connected to the top of the support plate 301. A translation motor 303 is fixedly connected to the front of the fixed frame 302. A screw 305 is fixedly connected to the output shaft of the translation motor 303. A moving plate 306 is threaded onto the outer side of the screw 305. A fixed block 307 is fixedly connected to the top of the moving plate 306. A connecting block 308 is fixedly connected to the top right side of the fixed block 307. A scraper 309 is fixedly connected to the right side of the connecting block 308. A sliding groove 321 is provided in the middle of the top of the fixed frame 302. The sliding groove 321 is slidably connected to the fixed block 307.

[0023] In this embodiment, coal is transported from left to right by the main body 1 of the conveying mechanism. The long materials can be blocked by the cooperation of the blocking strip 204 and the horizontal strip 205. Since the blocking strip 204 and the horizontal strip 205 are relatively thin strips, they will not affect the normal transport of coal. When long materials are blocked by the blocking strip 204, the cylinder 211 is activated to drive the piston rod to retract. This causes the connecting component 206 to rotate one end of the back of the long strip plate 203 around the fixed axis inside the mounting block 202 by a certain angle, so that the horizontal strip 205 is tilted with the back height higher than the front height. Then, the long materials slide down the surface of the horizontal strip 205 to the front, thus removing the materials.

[0024] The length of the magnetic frame 405 is the same as the width of the conveyor belt of the main body 1 of the conveyor mechanism. The rotating rod 403 is driven to rotate by the rotating motor 402, so the support rod 404 drives the magnetic frame 405 to rotate counterclockwise. The magnetic frame 405 can attract iron debris. Since the right side of the fixed frame 302 is close to the left side of the magnetic frame 405 but not in contact, the fixed frame 302 can intercept the debris attracted by the magnetic frame 405. The translation motor 303 is started to drive the screw 305 to rotate. Under the thread thrust of the screw 305, the moving plate 306 drives the fixed block 307 to move back and forth. Thus, the scraper 309 can scrape the iron debris intercepted on the top right side of the fixed frame 302 to the front or back, so as to prevent iron debris and long debris from entering the coal bunker and causing the coal bunker to be blocked.

[0025] The adsorption component 4 includes a support plate 401. A rotary motor 402 is fixedly connected to the front of the support plate 401. A rotary rod 403 is fixedly connected to the output shaft of the rotary motor 402. A support rod 404 is fixedly connected to the middle of the outer side of the rotary rod 403. A magnetic frame 405 is fixedly connected to the outer side of the support rod 404. A cylindrical frame 406 is fixedly connected to both the front and back of the magnetic frame 405. The cylindrical frame 406 is made of stainless steel.

[0026] The tops of the magnetic frame 405 and the cylindrical frame 406 are kept at a certain distance from the top of the main body 1 of the transmission mechanism, so as not to affect the normal transportation of coal. The length of the magnetic frame 405 is adapted to the width of the transmission belt of the main body 1 of the transmission mechanism.

[0027] A cylinder 211 is fixedly connected to the top of the inner wall of the fixing frame 201. A connecting component 206 is installed on the back of the piston rod of the cylinder 211. The end of the connecting component 206 away from the cylinder 211 is connected to the back of the top of the long strip plate 203.

[0028] The two ends of the connecting component 206 are connected to the piston rod of the cylinder 211 and the back of the top of the long strip plate 203 respectively through the rotating shaft. When the piston rod of the cylinder 211 is in the extended state, the long strip plate 203 remains in a horizontal state, and the horizontal strip 205 is in contact with the surface of the main body 1 of the transmission mechanism, which will not affect the normal transportation of coal.

[0029] The top of the fixed frame 302 is fixedly connected to a baffle 304, and a rectangular groove 341 is provided on the side of the baffle 304. The rectangular groove 341 is slidably connected to the connecting block 308.

[0030] During the movement of the movable plate 306, the connecting block 308 can slide along the inner side of the rectangular groove 341, and the baffle 304 can prevent iron impurities from falling into the interior of the fixed frame 302 through the slide groove 321.

[0031] The fixed frame 302 is fixedly connected to the inner side of the positioning rod 310, and the positioning rod 310 is slidably sleeved with the moving plate 306.

[0032] The movable plate 306 can be positioned to prevent it from tilting or shifting, so that when the screw 305 rotates, it can drive the movable plate 306 to move smoothly.

[0033] Working principle and usage process of this utility model:

[0034] In this embodiment, coal is transported from left to right by the main body 1 of the conveying mechanism. The long materials can be blocked by the cooperation of the blocking strip 204 and the horizontal strip 205. Since the blocking strip 204 and the horizontal strip 205 are relatively thin strips, they will not affect the normal transport of coal. When long materials are blocked by the blocking strip 204, the cylinder 211 is activated to drive the piston rod to retract. This causes the connecting component 206 to rotate one end of the back of the long strip plate 203 around the fixed axis inside the mounting block 202 by a certain angle, so that the horizontal strip 205 is tilted with the back height higher than the front height. Then, the long materials slide down the surface of the horizontal strip 205 to the front, thus removing the materials.

[0035] The length of the magnetic frame 405 is the same as the width of the conveyor belt of the main body 1 of the conveyor mechanism. The rotating rod 403 is driven to rotate by the rotating motor 402, so the support rod 404 drives the magnetic frame 405 to rotate counterclockwise. The magnetic frame 405 can attract iron debris. Since the right side of the fixed frame 302 is close to the left side of the magnetic frame 405 but not in contact, the fixed frame 302 can intercept the debris attracted by the magnetic frame 405. The translation motor 303 is started to drive the screw 305 to rotate. Under the thread thrust of the screw 305, the moving plate 306 drives the fixed block 307 to move back and forth. Thus, the scraper 309 can scrape the iron debris intercepted on the top right side of the fixed frame 302 to the front or back, so as to prevent iron debris and long debris from entering the coal bunker and causing the coal bunker to be blocked.
