Description

Technical Field

[0001] The invention belongs to the technical field of coal mine conveyors, and in particular relates to a safe coal mine conveyor for coal mine transportation. Background Art

[0002] At present, in the vast majority of coal mines, coal preparation plants and activated carbon companies in my country, the transportation of coal is mainly carried out by coal conveyors. Coal conveyors are important equipment for coal production. Coal transportation is based on transporting underground coal resources to the ground through conveyor belts to realize coal excavation, transportation and processing.

[0003] An important link in coal mine production is the coal mine transportation system. At present, the coal mine transportation system mainly adopts coal conveyor belt transportation. In coal mine transportation, coal conveyors generally have to carry out long distances, long working hours and heavy transportation. Since the coal falling position during use is relatively concentrated and uneven, it is easy to cause uneven force on the conveyor belt and large transportation inclination, which may cause the belt to slip, deviate, and break. In addition, traditional coal conveyors lack belt monitoring mechanisms. When the conveyor belt breaks due to quality problems such as overload and aging, the tight belt will quickly slide down due to the breakage, and even fly out and hit the staff. The large amount of scattered coal will also hit the personnel and equipment, thereby threatening the life safety of the staff and damaging nearby equipment and facilities, causing huge economic losses. In addition, the safety is relatively low, so there are deficiencies and it cannot meet the user's usage needs. Therefore, it is necessary to further improve it.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a safe coal conveyor for coal mine transportation is provided, in order to achieve a more practical purpose. Summary of the Invention

[0036] 3. The safe coal conveyor for coal mine transportation pushes the striking piece to retract based on the reaction force when the striking piece contacts the coal, and drives the unloading plate to squeeze the unloading air cushion through the movable rod, thereby achieving the purpose of buffering and unloading the striking piece. At the same time, the buffering piece and the unloading groove are combined with each other, which can improve the buffering effect of the striking piece on the one hand, and effectively enhance the stability of the movable rod during movement on the other hand. This setting effectively avoids damage to the striking piece, while enhancing the service life of the equipment and further improving its use effect.

[0037] 4. The safe coal conveyor for coal mine transportation scrapes the coal remaining on the surface of the conveyor belt through the cleaning plate to clean it.

[0063] The specific usage and function of this embodiment are as follows:

[0064] Working principle: At present, the transportation of coal is mainly carried out by coal conveyor, which is an important equipment for coal production. Coal mine transportation is based on transporting underground coal resources to the ground through conveyor belts to realize coal excavation, transportation and processing. When in use, the coal is piled on the top of the conveyor belt 4, and the conveyor motor 2 and the conveyor roller 3 are used to drive the conveyor belt 4 to move, so as to realize the transportation of coal. Since the coal is piled up randomly on the conveyor belt 4, there is a situation where it is piled in the same place. As the conveyor belt 4 drives the coal to move continuously, the uniform roller 71 is prompted to contact with the coal. The coal in the process of operation drives the uniform roller 71 to rotate, and the uniform roller 71 is used to evenly process the coal. At the same time, the setting of the vibration component 75 makes the uniform roller 71 vibrate when it comes into contact with the coal. The vibration spring 753 can enhance the vibration frequency of the uniform roller 71, thereby effectively enhancing the uniform effect of the uniform roller 71 on the coal and making the coal dispersed on the surface of the conveyor belt 4. At the same time, it can prevent the conveyor belt 4 from being stretched and damaged due to uneven force on the falling coal and offset of the falling coal position, effectively avoid the possibility of uneven force on the conveyor belt 4, and further improve the safety performance of the equipment.

[0065] During the operation of the conveyor belt 4, the outer side of the movable wheel 10 contacts the conveyor belt 4, and the force of the conveyor belt 4 during operation drives the movable wheel 10 and the movable roller 8 to rotate. The movable roller 8 drives the knocking assembly 9 to rotate synchronously during the rotation, so that the knocking member 93 knocks the coal, and the knocking member 93 is used to knock the larger coal loose and disperse it, which can further improve the uniformity of the coal and make the conveyor belt 4 more evenly stressed, further improving the use effect of the equipment.

[0066] In addition, when the striking piece 93 strikes the coal, there is some harder coal. When the striking piece 93 contacts the harder coal, it fails to break it. At this time, the reaction force when the striking piece 93 contacts the coal pushes the striking piece 93 to retract, and the movable rod 92 drives the unloading plate 94 to squeeze the unloading air cushion 95, thereby achieving the purpose of buffering and unloading the striking piece 93. In addition, when the movable rod 92 moves, the buffering piece 96 and the unloading groove 971 are combined with each other, which can improve the buffering effect of the striking piece 93 on the one hand, and effectively enhance the stability of the movable rod 92 when moving on the other hand. This arrangement effectively avoids damage to the striking piece 93, while extending the service life of the equipment and further improving its use effect.

[0067] The movable roller 8 drives the rotating shaft 1 81 to rotate synchronously during the rotation process, and utilizes the mutual cooperation between the rotating shaft 1 81, the linkage shaft 11 and the rotating shaft 2 131 to drive the cleaning roller 13 to rotate. During the rotation of the cleaning roller 13, the cleaning plate can be driven to scrape the coal remaining on the surface of the conveyor belt 4, and the coal is scraped clean, which is beneficial to the monitoring of the conveyor belt 4. During the rotation of the cleaning roller 13, the fixed ring 15 and the pushing member 151 are driven to rotate synchronously. When the pushing member 151 rotates, it will contact with the linkage member 163 and push the linkage member 163 to move upward, and the linkage member 163 is used to squeeze the inflatable airbag 162, and the air flow in the inflatable airbag 162 is ejected toward the conveyor belt 4 through the air nozzle 165. The ejected air The flow can blow clean the surface of the conveyor belt 4, thereby cleaning the coal dust on the surface of the conveyor belt 4. The intermittent setting of the pushing member 151 prompts the reset spring 164 to drive the linkage member 163 to reset, and then the inflation valve 166 is used to inflate the inflatable airbag 162. After inflation, the pushing member 151 pushes the linkage member 163 to squeeze it again, and the air nozzle 165 sprays out again, and the reciprocating cycle makes the scraper 14 clean the conveyor belt 4 while the cleaning component 16 runs synchronously. As the surface of the conveyor belt 4 is cleaned, the monitoring mechanism 18 is used to detect the conveyor belt 4, which can further enhance the monitoring effect of the monitoring mechanism 18 on the conveyor belt 4. When a crack is found, a message is sent to alarm, reminding the staff to replace and inspect it in time.
