Description
Technical Field
[0001] This invention relates to the field of conveying technology, specifically to a conveying device for coal gangue backfilling. Background Technology
[0002] Solid waste such as coal gangue is generated during coal mining and washing. Coal gangue can be backfilled, which not only solves the problem of waste disposal, but also replaces traditional filling materials and realizes resource reuse. During the backfilling process, conveying equipment is needed to transport the coal gangue to the mixing device for processing, so that it can be backfilled later. For example, the prior art patent with publication number "CN214934150U" entitled "A Coal Gangue Backfilling and Conveying Device" discloses a belt conveyor that transports coal gangue to the coal pit for backfilling. Simultaneously, the bolts fixing the support plate to the fixed angle frame are loosened, and the support plate is rotated and lowered along the support shaft. This allows the positioning rod at the bottom of the support plate to be inserted into the ground away from the coal pit for fixation, strengthening the positioning and fixing of the support frame and preventing displacement of the belt conveyor due to the collapse of the coal pit edge. This significantly improves the stability of the belt conveyor, ensures the efficiency of coal gangue transportation, and facilitates loading and unloading. Another example is the prior art patent with publication number "CN222555812U" entitled "A Coal Gangue Backfilling Conveying Device," which discloses... The bottom of the conveying device body is connected to a support base. By installing the support base, the conveying device body can be fixed to the ground. The top of the conveying device body is equipped with a frame. The frame body has a first bearing frame and a second bearing frame on the outside. The first bearing frame has a first breathable net inside, and a first activated carbon plate on top of the first breathable net. The second bearing frame has a second breathable net inside, and a second activated carbon plate on top of the second breathable net. The tops of the first and second bearing frames are fixedly connected to damping rods, and pressure plates are installed on the outside of the damping rods. By installing the frame, first bearing frame, second bearing frame, first activated carbon plate, and second activated carbon plate on the top of the conveying device body, the adsorption structure can be initially installed. Moreover, the activated carbon plate can adsorb dust, so its adsorption effect is good during use.
[0003] The existing coal gangue backfilling conveying equipment described above uses a combination of a first activated carbon plate and a second activated carbon plate to adsorb dust. While this prevents dust from escaping, the adsorption of dust by the first and second activated carbon plates is passive, resulting in slow adsorption efficiency and poor adsorption effect, which in turn leads to some dust escaping. Therefore, we propose a coal gangue backfilling conveying equipment to solve the problems mentioned above. Summary of the Invention
[0004] The purpose of this invention is to provide a conveying device for coal gangue backfilling, in order to solve the problem mentioned in the background art. Currently available coal gangue backfilling conveying devices rely on the combined use of a first activated carbon plate and a second activated carbon plate to adsorb dust. While this can prevent dust from escaping, the adsorption of dust by the first and second activated carbon plates is passive, resulting in slow adsorption efficiency and poor dust adsorption effect, which in turn leads to the problem of some dust escaping.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for coal gangue backfilling, comprising a support frame and a conveyor belt disposed on its inner side, wherein a main pipe is installed on the upper left side of the support frame via a support assembly, and the right side of the main pipe is connected to the left end of a first anti-escape pipe via a connecting hose, and the first anti-escape pipe is installed on the support frame located on the right side of the main pipe via an adjustment assembly.
[0006] Preferably, a drive roller is provided inside the rear side of the conveyor belt, and both ends of the drive roller are rotatably installed with the inner side of the support frame, and the right end of the drive roller passes through the right side of the support frame.
[0007] The above structure ensures that the drive drum rotates stably, driving the conveyor belt to rotate, which facilitates the conveyor belt to transport coal gangue effectively.
[0008] Preferably, the support assembly includes a threaded rod installed in a slot on the upper left side of the support frame, and a first support block is threadedly connected to the outer side of the threaded rod. The lower part of the first support block is engaged and slidably connected to the slot on the upper left side of the support frame, and a main pipe is fixedly fixed through the upper part of the first support block.
[0009] With the above structure, the slot on the upper left side of the support frame limits the first support block, so that when the threaded rod rotates later, it can stably drive the first support block connected to the outer thread to move back and forth, so that the first support block can drive the main pipe to move back and forth.
[0010] Preferably, the control component includes a second support block installed on a support frame located on the right side of the main tube, and a first anti-escape tube is fixedly fixed through the lower interior of the second support block, a guide rod is installed in a slot on the left side of the second support block, and a protruding post is fixed on the bottom surface of the second support block.
[0011] With the above structure, the second support block can support and install the first anti-escape tube, so that the first anti-escape tube is placed stably and horizontally on the conveyor belt. This facilitates the first anti-escape tube to adsorb and collect dust on the conveyor belt in the later stage, and prevents dust from escaping and polluting the surrounding environment during the conveying process.
[0012] Preferably, a manual telescopic rod is installed on the right side of the first support block, and a guide rod is provided through the inside of the right end of the manual telescopic rod. A connecting spring is nested on the outside of the manual telescopic rod, and a return spring is nested on the outside of the guide rod.
[0013] The above-described structure, along with the manual telescopic rod, not only facilitates the installation of the second support block but also allows for stable vertical movement of the second support block, thus meeting various usage requirements.
[0014] Preferably, the upper left surface of the support frame is provided with an inclined guide groove, and a guide block is installed inside the guide groove. The upper surface of the guide block is an inclined surface, and the lower end of the protrusion is inserted into the guide groove.
[0015] With the above structure, since the guide block with the inclined upper surface is installed in the guide groove, when the convex column moves to contact the guide block later, the guide block will apply an upward thrust to the convex column, thereby causing the guide block to drive the convex column to move up and down reciprocally.
[0016] Preferably, the protruding post forms a lifting structure through a guide block.
[0017] The above structure facilitates the convex column to drive the second support block to move up and down reciprocally, which in turn drives the first anti-escape tube to move up and down reciprocally, allowing for slight shaking of the first anti-escape tube.
[0018] Preferably, collars are rotatably installed on the outer sides of both the front and rear ends of the drive roller, and a connector is fixed below the collar. A scraper is installed at the lower end of the connector, and the inner side of the scraper is fitted to the outer side of the conveyor belt. A vertical rod is installed in a slot on the front side of the connector. An electric push rod is installed on the support frame located in front of the drive roller, and a push frame is fixed at the rear end of the electric push rod. A movable block is movably connected to the rear end of the push frame, and a movable block is provided through the outer side of the vertical rod.
[0019] With the above structure, the scraper reciprocates at a certain angle around the center of the drive roller, so that the scraper can actively remove dust and impurities from the outer side of the conveyor belt.
[0020] Preferably, a bracket is fixed below the scraper, and a second anti-escape tube is installed inside the bracket.
[0021] With the above-mentioned structure, the second anti-escape tube can actively adsorb and collect the impurities and dust scraped off by the scraper.
[0022] Preferably, the bottom surface of the bracket is fixed with an inclined guide plate.
[0023] With the above structure, the inclined guide plate also reciprocates at a certain angle with the center of the drive roller, so that the guide plate can guide the falling coal gangue to a farther position, avoiding the coal gangue falling at the rear end of the conveyor belt from accumulating in one place.
[0024] Compared with the prior art, the beneficial effects of the present invention are: the conveying equipment for coal gangue backfilling can increase the dust suction range of the first anti-escape pipe, thereby further improving the adsorption effect and efficiency of dust, and preventing dust from escaping during the conveying process of coal gangue. The specific details are as follows: (1) By using the main pipe in conjunction with the first row of first anti-escape pipes, the first row of first anti-escape pipes can actively adsorb and collect the dust generated above the conveyor belt. At the same time, by controlling the first anti-escape pipes to move back and forth and left and right, the dust suction range of the first anti-escape pipes can be increased, thereby further improving the adsorption effect and efficiency of dust and preventing dust from escaping during the conveying of coal gangue. (2) Furthermore, by setting the guide block with the upper surface inclined, the convex column drives the second support block and the first anti-escape tube to move up and down reciprocally, thereby facilitating the slight up and down shaking of the first anti-escape tube and preventing the dust suction head at the bottom of the first anti-escape tube from being blocked by dust. (3) The push frame can drive the connector and collar to rotate, thereby causing the collar to rotate around the center of the drive roller, which causes the connector to drive the scraper to rotate at a certain angle, so that the scraper can effectively remove the dust and impurities on the outside of the conveyor belt and actively collect them through the second anti-escape tube. (4) Furthermore, the bracket drives the inclined guide plate to reciprocate at a certain angle, which allows the guide plate to intermittently guide the coal gangue falling from the rear end of the conveyor belt to a more distant position, thus avoiding the coal gangue falling from the rear end of the conveyor belt from accumulating in one place and affecting the processing efficiency in the later stage.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Please see Figures 1-12 The present invention provides the following technical solution: Example 1: The coal gangue backfilling conveying equipment in this example can not only actively adsorb and collect dust to prevent it from escaping, but also increase the dust suction range of the first anti-escape pipe 6. This further improves the dust adsorption effect and efficiency, preventing dust from escaping during the conveying process of coal gangue. For the specific structure, please refer to the attached diagram. Figures 1-6As shown, the system includes a support frame 1 and a conveyor belt 2 disposed inside it. A main pipe 3 is installed on the upper left side of the support frame 1 via a support assembly, and the right side of the main pipe 3 is connected to the left end of a first anti-escape pipe 6 via a connecting hose. The first anti-escape pipe 6 is installed on the support frame 1 located on the right side of the main pipe 3 via an adjustment assembly. A drive roller 201 is disposed inside the rear side of the conveyor belt 2, and both ends of the drive roller 201 are rotatably mounted to the inner side of the support frame 1. The right end of the drive roller 201 penetrates the right side of the support frame 1. The support assembly includes a threaded rod 10 installed in a groove opened on the upper left side of the support frame 1, and a first support block 4 is threadedly connected to the outer side of the threaded rod 10. The lower part of the first support block 4 is slidably connected to the slot opened on the upper left side of the support frame 1, and the upper part of the first support block 4 is fixedly fixed with the main pipe 3. The control component includes a second support block 7 installed on the support frame 1 located on the right side of the main pipe 3, and the lower part of the second support block 7 is fixedly fixed with the first anti-escape tube 6. The left side of the second support block 7 is slotted and a guide rod 72 is installed. The bottom surface of the second support block 7 is fixed with a protruding post 71. The right side of the first support block 4 is installed with a manual telescopic rod 5, and the right end of the manual telescopic rod 5 is provided with a guide rod 72. The outer side of the manual telescopic rod 5 is nested with a connecting spring 51, and the outer side of the guide rod 72 is nested with a return spring 73.
[0029] First, the right end of the drive roller 201 is connected to an external servo motor via a coupling. The servo motor drives the drive roller 201 to rotate, which in turn drives the conveyor belt 2 to rotate as well, allowing the conveyor belt 2 to effectively transport the coal gangue backward. While the conveyor belt 2 is transporting the coal gangue, the front end of the threaded rod 10 is connected to the external servo motor via a coupling. The servo motor drives the threaded rod 10 to rotate clockwise and counterclockwise in a reciprocating motion. The external fan is then connected to the main pipe 3 and started. When the threaded rod 10 rotates clockwise, the first support block 4, which is threaded to the outside of the threaded rod 10, moves the main pipe 3 backward. Simultaneously, the first support block 4 moves the manual telescopic rod 5, the second support block 7, and the first anti-escape pipe 6 together. Moving backward, the protruding post 71 at the bottom of the second support block 7 moves within the guide groove 8. Since the guide groove 8 is inclined, the protruding post 71 moves backward and to the right simultaneously within the guide groove 8. At this time, the connecting hose at the connection between the main pipe 3 and the first anti-escape pipe 6 is stretched, the manual telescopic rod 5 is stretched, and the connecting spring 51 stores force. When the threaded rod 10 rotates counterclockwise, as described above, the main pipe 3 and the first anti-escape pipe 6 move forward, and the first anti-escape pipe 6 moves to the left. This operation is repeated, causing the first anti-escape pipe 6 to move back and forth and left and right, thus increasing the dust collection range of the first anti-escape pipe 6. This further improves the dust adsorption effect and efficiency, preventing dust from escaping during the conveying of coal gangue by the conveying equipment.
[0030] Example 2: The coal gangue backfilling conveying equipment in this example, based on Example 1, can also drive the first anti-escape pipe 6 to slightly sway up and down, preventing the dust suction head at the bottom of the first anti-escape pipe 6 from being blocked by dust. See attached diagram for the specific structure. Figures 5-8 As shown, the upper left side surface of the support frame 1 is provided with an inclined guide groove 8, and a guide block 9 is installed inside the guide groove 8. The upper surface of the guide block 9 is an inclined surface, and the lower end of the protruding column 71 is inserted into the guide groove 8. The protruding column 71 forms a lifting structure through the guide block 9.
[0031] When the protrusion 71 at the bottom of the second support block 7 moves in the guide groove 8, and the bottom end of the protrusion 71 contacts the guide block 9 with its upper surface inclined, the guide block 9 can automatically drive the protrusion 71 and the second support block 7 to move upward. At this time, one end of the manual telescopic rod 5 slides on the outside of the guide rod 72, and the return spring 73 stores force. This operation is repeated so that the protrusion 71 drives the second support block 7 and the first anti-escape tube 6 to move up and down in a reciprocating manner. This makes it easy to make the first anti-escape tube 6 slightly shake up and down, so as to avoid the dust suction head at the bottom of the first anti-escape tube 6 being blocked by dust.
[0032] Example 3: In this example, the coal gangue backfilling conveyor, based on Example 1, features a guide plate 17 that intermittently guides the coal gangue falling from the rear end of the conveyor belt 2 to a more distant location, preventing the coal gangue from accumulating in one place and affecting subsequent processing efficiency. The specific structure is shown in the attached diagram. Figures 9-12 As shown, collars 132 are rotatably mounted on the outer sides of both the front and rear ends of the drive roller 201, and a connector 13 is fixed below the collars 132. A scraper 16 is installed at the lower end of the connector 13. The inner side of the scraper 16 is fitted to the outer side of the conveyor belt 2. A vertical rod 131 is installed in a slot on the front side of the connector 13. An electric push rod 11 is installed on the support frame 1 located in front of the drive roller 201. A push frame 12 is fixed at the rear end of the electric push rod 11. A movable block 121 is movably connected to the rear end of the push frame 12. The movable block 121 is passed through the outer side of the vertical rod 131. A bracket 14 is fixed below the scraper 16. A second anti-escape tube 15 is installed inside the bracket 14. An inclined guide plate 17 is fixed on the bottom surface of the bracket 14.
[0033] When the conveyor belt 2 is conveying coal gangue, the electric push rod 11 is activated. The output end of the electric push rod 11 drives the push frame 12 to move back and forth. When the push frame 12 moves backward, the rear end of the push frame 12 pushes the connecting piece 13 to move backward, so that the connecting piece 13 and the collar 132 rotate around the center of the drive roller 201 at a certain angle. At this time, the movable block 121 slides on the outside of the vertical rod 131, thereby causing the connecting piece 13 to drive the scraper 16 to rotate back and forth at a certain angle, which facilitates the scraper 16 to move back and forth. The dust and impurities on the outside of the conveyor belt 2 are effectively scraped off. Then, the external fan is connected to the second anti-escape pipe 15, so that the second anti-escape pipe 15 actively adsorbs and collects the scraped dust and impurities. Similarly, the connecting piece 13 drives the bracket 14 and the guide plate 17 to reciprocate at a certain angle, so that the guide plate 17 intermittently guides the coal gangue falling from the rear end of the conveyor belt 2 to a farther position, so as to avoid the coal gangue falling from the rear end of the conveyor belt 2 from accumulating in one place and affecting the subsequent processing efficiency, thereby completing a series of tasks.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
