Description

Technical Field

[0001] The utility model relates to the technical field of coal conveying pipes, in particular to an anti-blocking and dust-suppressing curved drop pipe for coal conveying. Background Art

[0002] At present, coal mines are areas where humans exploit coal resources in coal-rich mining areas, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological layers rich in coal, usually including tunnels, shafts, and mining faces, etc. The transportation of coal in the mining and processing process is generally completed by conveyor belts and coal drop pipes.

[0003] The drop pipe in the prior art usually has a dust suppression component at the discharge port, which results in a large amount of dust flying out of the feed port to pollute the environment when the coal is delivered and transported, thereby reducing the dust suppression effect. In addition, the coal drop pipe is provided with a curved portion in order to suppress the dust, but the blockage in the curved portion of the coal drop pipe is not easy to clean. Therefore, we propose an anti-blocking and dust-suppressing curved drop pipe for coal transportation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a kind of anti-blocking and dust-suppressing curved drop pipe for coal transportation, which can effectively prevent coal dust from flying out from the entrance of the lower hopper to pollute the environment, thereby improving the dust suppression effect. At the same time, the first rotating shaft and the second rotating shaft are rotated to drive the connected dredging blade to move, and the moving dredging blade dredges and cleans the blockage in the corresponding curved part. In addition, the rotation of the first rotating shaft drives the auxiliary conveying component to work, so that the work of the auxiliary conveying component can increase the downward rotation angle of the baffle, thereby facilitating the transportation of coal, and can effectively solve the problems in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a blocking and dust suppression type curved drop pipe for coal transportation, comprising a drop hopper, a drop pipe, an auxiliary conveying assembly and a driving assembly;

[0006] The lower surface of the lower hopper is connected and two dropping pipes are installed, and the lower surface of the lower hopper is provided with a guide groove at the connection point between the dropping pipe and the dropping pipe, and the dropping pipe includes a second straight portion, a curved portion and a first straight portion from top to bottom, the upper end of the first straight portion is connected to the lower hopper, the curved portion on the left side is rotatably installed with a second rotating shaft, and the curved portion on the right side is rotatably installed with the first rotating shaft, and a plurality of dredging blades are evenly installed on the first rotating shaft and the second rotating shaft, and a first pulley is installed at the front end of the second rotating shaft, and a second pulley is installed at the front end of the first rotating shaft, and the first pulley and the second pulley are connected through belt transmission. Pins are rotatably installed on the left and right sides of the interior of the lower hopper, and a baffle is installed on the pin. One end of a tension spring is installed on the upper surface of the baffle, and the other end of the tension spring is connected to the corresponding inner wall of the lower hopper. A driving assembly is installed on the rear side of the left dropping pipe, and the driving assembly is connected to the rear end of the second rotating shaft, and the rear end of the first rotating shaft is connected to the auxiliary conveying assembly.

[0007] Furthermore, the auxiliary conveying assembly includes a mounting rod and a pinion mounted on the rear end of the first rotating shaft, a third rotating shaft is rotatably mounted on the side of the lower hopper, a large gear is mounted on the rear end of the third rotating shaft, the large gear and the pinion are meshed and connected, the front end of the third rotating shaft is mounted on one end of the mounting rod, the mounting rod is located in the lower hopper, and the third rotating shaft is located above the baffle. The first rotating shaft rotates to drive the pinion to rotate, the small gear rotates to drive the large gear to rotate, the large gear rotates to drive the third rotating shaft to rotate, and the third rotating shaft rotates to drive the mounting rod to rotate. When the mounting rod rotates clockwise or counterclockwise to the bottom and contacts the baffle on one side, the baffle opening angle can be adjusted to facilitate coal transportation. When the baffle opening angle is the largest and the mounting rod cannot rotate, the first rotating shaft rotates in the opposite direction to contact the other baffle, thereby not affecting the coal transportation efficiency, and the large gear and the pinion mesh to achieve speed change, thereby effectively avoiding affecting the cleaning efficiency of the blockage.

[0008] Furthermore, the driving assembly includes a motor bracket installed at the rear side of the left drop tube, a motor is installed on the motor bracket, an output shaft of the motor is connected to the rear end of the second rotating shaft through a coupling, and an input end of the motor is electrically connected to an output end of an external controller. The motor is controlled by the external controller, and the motor drives the second rotating shaft to rotate, thereby completing the rotation of the second rotating shaft by electric power.

[0009] Compared with the prior art, the utility model has the following beneficial effects: when the coal is poured into the lower hopper due to the anti-blocking and dust-suppressing curved drop pipe for coal conveying, the gravity of a large amount of coal creates a downward force on the baffle, so that under the rotation of the pin shaft, the two baffles will rotate downward to drop the coal into the drop pipe, and at the same time, under the elastic force of the tension spring, the baffle will have the force to drive itself to reset, thereby effectively preventing the coal dust from flying out from the entrance of the lower hopper to pollute the environment, thereby improving the dust suppression effect, and at the same time, by driving the component to The second rotating shaft is driven to rotate, and the rotation of the second rotating shaft drives the first pulley to rotate. Under the action of the first pulley, the second pulley and the belt, the rotation of the first pulley drives the second pulley to rotate, and the rotation of the second pulley drives the first rotating shaft to rotate. Therefore, the rotation of the first rotating shaft and the second rotating shaft drives the dredging blade connected to them to move, so that the blockage in the corresponding curved part is dredged and cleaned by the dredging blade. At the same time, the rotation of the first rotating shaft drives the auxiliary conveying component to work, so that the auxiliary conveying component can increase the downward rotation angle of the baffle, thereby facilitating the transportation of coal.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-2 , This embodiment provides a technical solution: a blocking and dust suppression type curved drop pipe for coal transportation, comprising a lower hopper 1, a drop pipe, an auxiliary conveying component and a driving component;

[0015] The lower surface of the lower hopper 1 is connected and installed with two dropping pipes. A guide groove 14 is provided at the connection point between the lower surface of the lower hopper 1 and the dropping pipe. The dropping pipe includes a second straight portion 8, a curved portion 5 and a first straight portion 7 from top to bottom. The upper end of the first straight portion 7 is connected to the lower hopper 1. The curved portion 5 on the left is rotatably installed with a second rotating shaft 18, and the curved portion 5 on the right is rotatably installed with a first rotating shaft 13. The front end of the second rotating shaft 18 is installed with a first pulley 6, and the front end of the first rotating shaft 13 is installed with a second pulley 10. The first pulley 6 and the second pulley 10 are connected through a belt 9 transmission. Pins are rotatably installed on both sides of the interior of the lower hopper 1, and a baffle 2 is installed on the pin. One end of a tension spring 4 is installed on the upper surface of the baffle 2, and the other end of the tension spring 4 is connected to the corresponding inner wall of the lower hopper 1. A driving assembly is installed on the rear side of the left dropping pipe, and the driving assembly is connected to the rear end of the second rotating shaft 18, and the rear end of the first rotating shaft 13 is connected to the auxiliary conveying assembly.

[0016] When in use, coal is poured into the lower hopper 1. At this time, the gravity of a large amount of coal creates a downward force on the baffle 2, so that under the rotation of the pin shaft, the two baffles 2 will rotate downward to drop the coal into the drop tube. At the same time, under the elastic force of the tension spring 4, the baffle 2 will have a force to drive itself to return to its original position, thereby effectively preventing coal dust from flying out of the entrance of the lower hopper 1 to pollute the environment, thereby enhancing the dust suppression effect. At the same time, the second shaft 18 is driven to rotate by the driving component, and the rotation of the second shaft 18 drives the first pulley 6 to rotate. Under the action of the first pulley 6, the second pulley 10 and the belt 9, the rotation of the first pulley 6 drives the second pulley 10 to rotate, and the rotation of the second pulley 10 drives the first rotating shaft 13 to rotate, so that the rotation of the first rotating shaft 13 and the second rotating shaft 18 drives the dredging blade 17 connected to them to move, so that the dredging blade 17 is used to dredge and clean the blockage in the corresponding curved portion 5. At the same time, the rotation of the first rotating shaft 13 drives the auxiliary conveying component to work, so that the auxiliary conveying component can increase the downward rotation angle of the baffle 2, thereby facilitating the transportation of coal.

[0017] The auxiliary conveying assembly includes a mounting rod 3 and a pinion 12 mounted on the rear end of the first rotating shaft 13. A third rotating shaft is rotatably mounted on the side of the lower hopper 1. A large gear 11 is mounted on the rear end of the third rotating shaft. The large gear 11 and the pinion 12 are meshed and connected. The front end of the third rotating shaft is mounted on one end of the mounting rod 3. The mounting rod 3 is located in the lower hopper 1, and the third rotating shaft is located above the baffle 2. The first rotating shaft 13 rotates to drive the pinion 12 to rotate, the pinion 12 rotates to drive the large gear 11 to rotate, the large gear 11 rotates to drive the third rotating shaft to rotate, and the third rotating shaft rotates to drive the mounting rod 3 to rotate. When the mounting rod 3 rotates clockwise or counterclockwise to the bottom and contacts the baffle 2 on one side, the opening angle of the baffle 2 can be adjusted to facilitate coal transportation. When the opening angle of the baffle 2 is the largest and the mounting rod 3 cannot rotate, the first rotating shaft 13 rotates in the opposite direction to contact the other baffle 2, so as not to affect the transportation efficiency of the coal. The large gear 11 and the pinion 12 are meshed to achieve speed change, thereby effectively avoiding affecting the cleaning efficiency of the blockage.

[0018] The driving assembly includes a motor bracket 16 installed at the rear side of the left drop tube, and a motor 15 is installed on the motor bracket 16. The output shaft of the motor 15 is connected to the rear end of the second rotating shaft 18 through a coupling, and the input end of the motor 15 is electrically connected to the output end of the external controller. The motor 15 is controlled by the external controller to drive the second rotating shaft 18 to rotate, thereby completing the rotation of the second rotating shaft 18 by electric power.

[0019] The working principle of the anti-blocking and dust-suppressing curved drop pipe for coal conveying provided by the utility model is as follows: when in use, the coal is poured into the lower hopper 1. At this time, the gravity of a large amount of coal creates a downward force on the baffle 2, so that under the rotation of the pin shaft, the two baffles 2 will rotate downward to drop the coal into the drop pipe. At the same time, under the elastic force of the tension spring 4, the baffle 2 will have a force to drive itself to return to its original position, thereby effectively preventing the coal dust from flying out from the entrance of the lower hopper 1 to pollute the environment, thereby enhancing the dust suppression effect. At the same time, the second rotating shaft 18 is driven to rotate by the driving component, and the second rotating shaft 18 is driven to rotate. The rotation of the shaft 18 drives the first pulley 6 to rotate. Under the action of the first pulley 6, the second pulley 10 and the belt 9, the rotation of the first pulley 6 drives the second pulley 10 to rotate. The rotation of the second pulley 10 drives the first rotating shaft 13 to rotate. Therefore, the rotation of the first rotating shaft 13 and the second rotating shaft 18 drives the dredging blade 17 connected to them to move, so that the dredging blade 17 is used to dredge and clean the blockage in the corresponding curved portion 5. At the same time, the rotation of the first rotating shaft 13 drives the auxiliary conveying component to work, so that the auxiliary conveying component can increase the downward rotation angle of the baffle 2, thereby facilitating the transportation of coal. The first rotating shaft 13 rotates to drive the pinion 12 to rotate, the pinion 12 rotates to drive the large gear 11 to rotate, the large gear 11 rotates to drive the third rotating shaft to rotate, and the third rotating shaft rotates to drive the mounting rod 3 to rotate. When the mounting rod 3 rotates clockwise or counterclockwise to the bottom and contacts the baffle 2 on one side, the opening angle of the baffle 2 can be adjusted to facilitate coal transportation. When the opening angle of the baffle 2 is the largest and the mounting rod 3 cannot rotate, the first rotating shaft 13 rotates in the opposite direction to contact the other baffle 2, so as not to affect the transportation efficiency of the coal, and the large gear 11 and the pinion 12 mesh to achieve speed change, thereby effectively avoiding affecting the cleaning efficiency of the blockage. The motor 15 is controlled by an external controller to work, and the motor 15 drives the second rotating shaft 18 to rotate, so as to complete the rotation of the second rotating shaft 18 by electric power.

[0020] It is worth noting that in this embodiment, the core chip of the external controller is an STC single-chip microcomputer, specifically, the model is STC15W204S, and the motor 15 can be freely configured according to the actual application scenario. The motor 15 can be a JE series single-phase servo motor produced by Beijing Mitsubishi Electric (China) Co., Ltd. The external controller controls the operation of the motor 15 using a method commonly used in the prior art.
