DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-9 The present invention provides a technical solution: an electrically automatically controlled long-distance coal transportation device, which uses a screw conveyor as the main transportation form and is set in relatively flat areas and coal transfer points. Specifically, it includes several auxiliary screw conveyors 2, spring conveying pipes 4 and at least one main screw conveyor 1. The main screw conveyor 1 is set at the coal transfer point to collect the coal collected from the Jiwo coal mine and transport it to the coal transfer point. The auxiliary screw conveyor 2 is set in a relatively flat area in the mine where gravity transportation is not easy to use, and is used to connect the main screw conveyor 1 and the spring conveying pipe 4.

[0034] The feed ends of several of the spring conveying pipes 4 are arranged near the mining equipment of Jiwo Coal Mine, and the discharge ends of several of the spring conveying pipes 4 are connected to the feed port of the auxiliary screw conveyor 2 or the feed port of the main screw conveyor 1. The discharge port of the auxiliary screw conveyor 2 is connected to the feed port of the main screw conveyor 1 through the connecting pipe 3. The spring conveying pipe 4 conveys the coal collected by the mining equipment of Jiwo Coal Mine downward into the main screw conveyor 1 or the auxiliary screw conveyor 2 by gravity and finally into the main screw conveyor 1. The spring conveying pipe 4 is similar to a spring and can bend and expand and deform. It can be an integral pipeline or it can be composed of an indefinite number of segmented spring conveying pipes connected to each other, so that it can be set to a corresponding shape according to the mountain shape and the conveying route, etc., to ensure the smoothness of the conveying channel.

[0035] The spring conveying pipe 4 is respectively provided with a pushing mechanism and an adjusting mechanism. The adjusting mechanism is arranged near the pushing mechanism. The pushing mechanism is arranged in some flat sections or horizontal sections to push the coal in the spring conveying pipe 4 to prevent the coal from piling up there and affecting the conveying. At the same time, an adjusting mechanism is arranged to adjust the shape of the spring conveying pipe 4 when the coal is piled up or stuck. The accumulated coal can be loosened by extrusion, deformation, shaking, etc., and the pushing mechanism can be cooperated to push it to continue to convey it downward.

[0036] The present application uses the spring conveying pipe 4 to convey the coal collected from the Jiwo coal mine to the main screw conveyor 1 or the auxiliary screw conveyor 2 by gravity and in cooperation with the pushing mechanism and the adjusting mechanism, and finally sends it into the main screw conveyor 1, so as to realize long-distance transportation of the coal collected from the Jiwo coal mine, reduce the difficulty of transportation, and improve work efficiency. The spring conveying pipe 4 can be bent, deformed and assembled, etc., and can adapt to different mountain shapes. It can be recovered after the collection of a Jiwo coal mine is completed and put into use again in other Jiwo coal mine areas, thereby reducing mining costs.

[0037] The preferred technical solution is that the spring conveying pipe 4 is arranged along the mine body, so that the coal mined by external mining equipment can be transported to the main screw conveyor 1 or the auxiliary screw conveyor 2 through the spring conveying pipe 4, and a positioning rod 5 is arranged on the outside of the spring conveying pipe 4. The positioning rod 5 is fixedly arranged at the corner of the spring conveying pipe 4, and is used to limit the spring conveying pipe 4 according to the shape of the mountain and the conveying route so that it connects the mining point and the main screw conveyor 1 or the auxiliary screw conveyor 2.

[0038] According to a preferred technical solution, the upper surface of the spring conveying pipe 4 is open, which facilitates the pushing mechanism to push the coal in the spring conveying pipe 4, and is also convenient for inspection and processing during inspection and maintenance by staff.

[0039] Further preferably, the cross-sectional shape of the spring conveying tube 4 is an isosceles trapezoid whose lower base is shorter than the upper base, that is, its opening is larger and the bottom is smaller, so that the coal and the like are concentrated in the middle of the bottom, avoiding being too dispersed on both sides and not easy to concentrate in one place, making it easier to gather together and transport downward along the spring conveying tube 4 under the action of gravity.

[0040] The preferred technical solution is that the spring conveying tube 4 contains several steel rings evenly arranged along its length direction. The main body of the spring conveying tube 4 is a semi-circular wear-resistant plastic such as polytetrafluoroethylene or nylon, and can also be engineering plastics to extend its service life. The steel ring is also arranged in the material; the wear-resistant rubber is elastic between the wear-resistant plastics. The wear-resistant rubber is thinner and the wear-resistant plastic is thicker. When the spring conveying tube 4 is compressed, the wear-resistant rubber is squeezed, and when the spring conveying tube 4 is elongated, the wear-resistant rubber is stretched, that is, the spring conveying tube 4 has elasticity and scalability, so that it can adapt to the shape of the mountain. By setting up multiple spring conveying tubes 4, mining operations can be carried out on multiple relatively scattered Jiwo coal mines at the same time, which greatly improves work efficiency.

[0041] The preferred technical solution is that the pushing mechanism includes two mounting seats 6 installed on both sides of the upper surface of the spring conveying tube 4, and a rotating shaft 11 is rotatably arranged between the two mounting seats 6, and a motor seat 8 is installed on the outer surface of one of the mounting seats 6, and a pushing motor 10 is installed on the side surface of the motor seat 8. The output shaft of the pushing motor 10 passes through the motor seat 8 and is connected to one end of the rotating shaft 11 through a coupling, and a bearing seat 9 is provided on the outer surface of the other mounting seat 6, and the bearing installed in the bearing seat 9 is connected to the other end of the rotating shaft 11, and a trapezoidal pushing plate 12 is fixedly provided on the outer surface of the rotating shaft 11, and the pushing motor 10 drives the pushing plate 12 to rotate through the rotating shaft 11. When the pushing plate 12 rotates, the coal in the spring conveying tube 4 is pushed to the lower side where gravity can be used to continue to convey the coal or to the next pushing mechanism, thereby continuously conveying the coal until it is sent into the main screw conveyor 1 or the auxiliary screw conveyor 2, completing the long-distance coal transportation to the Jiwo Coal Mine.

[0042] A further preferred technical solution is that screw holes are provided on the upper surfaces of both sides of the spring delivery tube 4 and the upper surface of the mounting seat 6, and mounting bolts 7 are threadedly connected to the screw holes. The mounting seat 6 is installed on the spring delivery tube 4 through the mounting bolts 7 and can be installed to the corresponding position according to actual needs, thereby greatly improving the flexibility of use.

[0043] According to the preferred technical solution, a first slide groove 15 is provided on the upper surface of the push plate 12, and a trapezoidal main telescopic plate 13 is slidably arranged in the first slide groove 15, and a plurality of springs 16 are evenly arranged between the main telescopic plate 13 and the inner surface of the first slide groove 15. When the push plate 12 rotates into the spring conveying tube 4 to push the internal coal, the main telescopic plate 13 is kept at the outermost side under the elastic force of the spring 16 to push the coal at the bottom; when the material is stuck, the main telescopic plate 13 is stuck, and the push plate 12 continues to rotate, which will cause the main telescopic plate 13 to move into the first slide groove 15, thereby compressing the spring 16 to prevent the push plate 12 from being stuck and causing damage to the push motor 10.

[0044] A further preferred technical solution is that two second slide grooves 19 are symmetrically provided on the two oblique side surfaces of the push plate 12, and a rectangular side telescopic plate 14 is slidably arranged in the second slide groove 19, and a plurality of springs 16 are evenly arranged between the side telescopic plate 14 and the inner surface of the second slide groove 19. When the push plate 12 rotates into the spring conveying tube 4 to push the internal coal, the side telescopic plate 14 is kept at the outermost side under the elastic force of the spring 16, and the coal on both sides of the lower part of the spring conveying tube 4 is pushed and conveyed; when the material is stuck, the side telescopic plate 14 is stuck, and the push plate 12 continues to rotate, which will cause the side telescopic plate 14 to move into the second slide groove 19, thereby compressing the spring 16 to prevent the push plate 12 from being stuck and causing damage to the push motor 10.

[0045] The preferred technical solution is that the adjustment mechanism includes a mounting stud 20, a threaded sleeve 21, a pull rod 23, a rack 24, a housing 25, a gear 27 and a drive motor 28. Two screw holes are symmetrically provided on the upper surfaces of both sides of the spring delivery tube 4. The two mounting studs 20 are threadedly connected in the corresponding screw holes. The threaded sleeve 21 is threadedly connected to the outside of the mounting stud 20. The pull rod 23 is arranged on the outside of the threaded sleeve 21 and connected to the rack 24. There are two racks 24, and both racks 24 are L-shaped. The two racks 24 are slidably arranged in the slide groove provided on the housing 25. The drive motor 28 is fixedly installed at the center of the side surface of the housing 25, and the output shaft of the drive motor 28 penetrates the housing 2 5 and connected with the gear 27, the two racks 24 are centrally symmetrically arranged with the output shaft center of the driving motor 28 as the center point, the two racks 24 are respectively arranged on the upper and lower sides of the gear 27 and are meshed with the gear 27. When the spring conveying pipe 4 is jammed due to coal accumulation, the driving motor 28 is turned on, the driving motor 28 drives the gear 27 to rotate, the gear 27 drives the two racks 24 to move toward the middle, and the two racks 24 drive the two mounting studs 20 to move toward the middle through the pull rod 23, thereby contracting the two side plates of the spring conveying pipe 4 to deform it, squeezing the coal toward the middle, so that the coal is concentrated in the middle position, so that it is easy to be pushed out by the pushing plate 12, reducing the probability of jamming and improving the conveying efficiency.

[0046] A further preferred technical solution is that an annular groove is provided on the outer surface of the threaded sleeve 21, a rotating ring 22 is rotatably arranged in the annular groove, and the pull rod 23 is fixedly arranged on the outer surface of the rotating ring 22. When the threaded sleeve 21 is rotated on the mounting stud 20 to adjust the height, the pull rod 23 can be rotated through the rotating ring 22 so that it always remains connected to the shell 25.

[0047] A further preferred technical solution is that two T-shaped slide rails 26 are symmetrically arranged on both side surfaces of the rack 24, and the inner surface of the shell 25 is provided with slide rail grooves corresponding to the slide rails 26. The two racks 24 are slidably arranged in the slide rail grooves in the shell 25 through the slide rails 26, ensuring that they maintain their angles and directions when moved by the gears 27, and the adjustment is more stable.

[0048] The preferred technical solution is that a battery 32 and a controller 33 are arranged on the mounting base 6 or on the ground near the mounting base 6. The battery 32 is preferably a commonly used lithium battery or lead-acid battery. The controller 33 may include a control box and an internal PLC controller and a control switch, etc. The PLC controller may be a commonly used Mitsubishi FX2N series PLC controller, or a single-chip microcomputer or other commonly used microprocessors, etc. The battery 32 is electrically connected to the controller 33 to power it and other electrical components; the input end of the main screw conveyor 1, the input end of the auxiliary screw conveyor 2, the input end of the push motor 10 and the input end of the drive motor 28 are all electrically connected to the output end of the controller 33, and the controller 33 controls the switches and gear power of each electrical component according to a preset program to realize electrical automatic control of long-distance coal transportation.

[0049] An optional technical solution is that 3-6 mounting grooves 17 are provided on the inner surface of the first chute 15 and the inner surface of the second chute 19, and a distance sensor 18 is installed in the mounting groove 17. The output end of the distance sensor 18 is electrically connected to the input end of the controller 33, which is used to detect the positions of the main telescopic plate 13 and the side telescopic plate 14, and send a corresponding signal to the controller 33. The controller 33 compares the detected distance value with the preset value to determine whether the main telescopic plate 13 and the side telescopic plate 14 cannot be normally extended for a long time or are in a tilted state for a long time, and then determines that a jam has occurred on the spring conveying tube 4, and then automatically controls the adjustment mechanism to adjust the angle of the spring conveying tube 4, so that the coal stuck there can be moved under the continuous contraction and expansion of the wall of the spring conveying tube 4, so that it is convenient for the pushing mechanism to continue to push it down, thereby ensuring the normal transportation of the coal and further improving the degree of automation.

[0050] The interior of the rotating shaft 11 is hollow and is used to set a wire connected to each distance measuring sensor 18. The wire is connected to the controller 33 through a collector ring to avoid damage to the wire when the rotating shaft 11 drives the push plate 12 to rotate.

[0051] An optional technical solution is that a wireless transmission module 34 is also provided on the controller 33, preferably a commonly used Wi-Fi module or a 5G communication module. The controller 33 is bidirectionally electrically connected to the wireless transmission module 34, and the controller 33 is bidirectionally electrically connected to the control center 35 through the wireless transmission module 34. The control center 35 is generally arranged in the central control room of the coal mine, and mainly includes a computer, a display and other peripherals, etc., and can also be a commonly used electrical control cabinet. The controller 33 sends the data and results of its analysis and judgment to the terminal of the control center 35 through the wireless transmission module 34. The staff views the analysis data and results through the display. When an abnormality is found somewhere, the maintenance personnel are notified to go to the corresponding location for inspection and maintenance, etc., to avoid affecting the mining and transportation of coal in the Jiwo Mine.

[0052] The controller 33 at each pushing mechanism and adjusting mechanism has its own corresponding number and position, etc., and this information is also stored in the memory of the control center 35. When an abnormality occurs, the staff can immediately know which position and number of the controller 33 it is, which is convenient for quick viewing and maintenance, thereby improving work efficiency.

[0053] As a further optional technical solution, the controller 33 can also be bidirectionally electrically connected to the mobile terminal 36 via the wireless transmission module 34. The mobile terminal 36 can be a smart phone or PDA with a corresponding APP installed, which is carried by the inspection personnel. The controller 33 sends the data and results of its analysis and judgment to the mobile terminal 36 via the wireless transmission module 34. When an abnormal situation occurs, the built-in software of the mobile terminal 36 reminds the inspection personnel through a speaker, etc., and the inspection personnel can go to the corresponding location for inspection and maintenance, thereby further improving work efficiency.

[0054] The main screw conveyor 1, auxiliary screw conveyor 2, push motor 10, drive motor 28, distance sensor 18, controller 33, wireless transmission module 34 and mobile terminal 36 used in this application are all electrical equipment or electronic components commonly used in the prior art. Their specific structures, working principles and circuit connections are all well-known technologies and will not be described in detail here.

[0055] A capstan 29 is provided on the other side of the housing 25, and the output shaft of the driving motor 28 passes through the gear 27 and the other side surface of the housing 25 to be connected to the capstan 29. Two rope grooves are provided on the capstan 29, and a rope 30 is provided in each of the two rope grooves. Two rope seats 31 are symmetrically provided at the bottom or middle of the inner surface of the spring conveying tube 4. The rope seats 31 can be fixedly installed or detachably installed by bolts, pins, etc. The ends of the two ropes 30 are fixedly connected to the two rope seats 31 respectively. The driving motor 28 is driven by the gear 27. When the wheel 27 drives the two racks 24 to move and then drives the spring conveying tube 4 to retract through the pull rod 23 and the mounting stud 20, the driving motor 28 simultaneously drives the capstan 29 to rotate, winds up the twisting rope 30, and then pulls the twisting rope seat 31 upward, so that the lower parts of both sides of the spring conveying tube 4 are also lifted upward, thereby shortening the distance of the lower part of the spring conveying tube 4, so that the coal is further concentrated in the middle position, and with the adaptive extension of the main extension plate 13 and the side extension plate 14, it is easier to be pushed and moved by the pushing mechanism, further ensuring the normal transportation of the coal.
