Coal mine conveyors have low noise and simple structure during coal mine transportation, and can effectively complete horizontal or inclined transportation of coal mines.

[0003] At present, the existing conveyor is generally composed of a driving motor, a frame, conveyor rollers and a conveyor belt. When in use, the driving motor drives the conveyor rollers to move, and the conveyor belts are driven to move through the conveyor rollers, thereby realizing the transportation of coal blocks. However, since the length of the existing conveyor is generally fixed, an additional conveyor needs to be added when long-distance transportation is required, which undoubtedly increases the cost of use and is difficult to adapt according to the actual distance required, making the use of the conveyor more inconvenient.

The top of one threaded plate is welded and connected to the No. 1 bracket, and the top of the other threaded plate is welded and connected to the No. 2 bracket. The inner side of the No. 1 bracket is rotatably connected to the No. 1 extension roller, the inner side of the No. 2 bracket is rotatably connected to the No. 2 extension roller, and one side of the frame is rotatably connected to the supporting roller.

[0008] Preferably, the bottom end of the support platform is symmetrically welded to a limited position frame, the two groups of frames are internally welded to a transverse plate, and the bottom end of the frame is located below the transverse plate and is welded to a roller.

[0011] In summary, the utility model mainly has the following beneficial effects:

[0012] The length of the existing conveyor is generally fixed, so when long-distance transportation is required, an additional conveyor needs to be added, which increases the cost of use and is difficult to adapt according to the actual distance required, making it inconvenient to use. The utility model is provided with an extension mechanism, a No. 1 moving mechanism, a No. 2 moving mechanism and a roller. When the rotating motor is working, the output end of the rotating motor drives the threaded rod to rotate. Since the threads at both ends of the threaded rod have opposite rotation directions, the threaded plate makes a horizontal approaching movement, and the conveyor belt is relatively loosened. At the same time, the two threaded columns are rotated together under the action of the No. 2 pulley group and the No. 1 pulley group. Since the threads at both ends of the threaded column have opposite rotation directions, the two groups of threaded cylinders make opposite horizontal movements. Since the threads of the threaded column and the threaded rod have opposite rotation directions, the frame makes a horizontal away movement under the action of the roller, thereby realizing the extension operation of the conveyor belt, so that the conveyor body has an extension function, so that there is no need to add an additional conveyor for long-distance transportation, which reduces the cost of use, and can be adapted according to the required distance, which is more convenient to use.

[0018] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0019] The following describes an embodiment of the utility model based on its overall structure.

[0020] A conveyor having an extended structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a conveyor body 1, and the conveyor body 1 includes a frame 101, a conveyor roller 102 and a conveyor belt 103. The frame 101 is internally rotatably connected to the conveyor roller 102, and the conveyor belt 103 is wound around the outer sides of the two conveyor rollers 102. The driving motor drives the conveyor roller 102 to move, and the conveyor belt 103 is driven to move through the conveyor roller 102, thereby realizing the transportation of coal blocks.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the bottom end of the support platform 3 is symmetrically welded to the limiting frame 6 , and the threaded barrel 501 and the support platform 3 form a sliding structure through the limiting frame 6 .

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the two groups of the racks 101 are welded with a transverse plate 7, and the bottom end of the rack 101 is located below the transverse plate 7 and is welded with a roller 8. When the rack 101 moves, the roller 8 can increase the convenience of movement of the rack 101.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the top of the threaded plate 403 is provided with an extension mechanism 2 that penetrates the conveyor belt 103, and the extension mechanism 2 is composed of a No. 1 bracket 201, a No. 1 extension roller 202, a No. 2 bracket 203, a No. 2 extension roller 204 and a roller 205. The top of one of the threaded plates 403 is welded to the No. 1 bracket 201, and the top of the other threaded plate 403 is welded to the No. 2 bracket 203. The inner side of the No. 1 bracket 201 is rotatably connected to the No. 1 extension roller 202, and the inner side of the No. 2 bracket 203 is rotatably connected to the No. 2 extension roller 204, and one side of the frame 101 is rotatably connected to the roller 205;

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the cooperation between the No. 1 extension roller 202 and the No. 2 extension roller 204 can realize the storage of part of the conveyor belt 103, and at the same time, the conveyor belt 103 can be relaxed when the threaded plate 403 moves closer, thereby facilitating the extension of the conveyor.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that a support platform 3 is provided below the conveyor belt 103, and a No. 1 moving mechanism 4 is provided at the top of the support platform 3. The No. 1 moving mechanism 4 is composed of a rotating motor 401, a threaded rod 402 and a threaded plate 403. The threaded rod 402 is rotatably connected to the vertical plate at the top of the support platform 3 through a bearing, and a rotating motor 401 connected to the threaded rod 402 through a coupling is installed on one side of the vertical plate. The outer surface of the threaded rod 402 is threadedly connected to the threaded plate 403, and the threads at both ends of the threaded rod 402 have opposite rotation directions.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4It can be seen that when the rotating motor 401 is working, the output end of the rotating motor 401 drives the threaded rod 402 to rotate. Since the threaded rod 402 is threadedly connected to the threaded plate 403, and the threads at both ends of the threaded rod 402 have opposite rotation directions, the threaded plate 403 moves toward each other in the horizontal direction, making the conveyor belt 103 relatively loose, thereby facilitating the subsequent extension of the conveyor.

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that a No. 2 moving mechanism 5 penetrating the limit frame 6 is arranged between the two horizontal plates 7, and the No. 2 moving mechanism 5 is composed of a threaded cylinder 501, a threaded column 502, a No. 1 pulley group 503 and a No. 2 pulley group 504. A threaded column 502 is rotatably connected to the vertical plate at the bottom end of the support platform 3 through a bearing, and the outer surface of the threaded column 502 is threadedly connected to a threaded cylinder 501 penetrating the limit frame 6 and welded to the horizontal plate 7, and the outer sides of the two threaded columns 502 are symmetrically sleeved with the No. 1 pulley group 503, and the outer surfaces of one threaded column 502 and the threaded rod 402 are sleeved with the No. 2 pulley group 504, and the threaded rotation directions of the two ends of the threaded column 502 are opposite, and the threaded rotation directions of the outer surfaces of the two threaded columns 502 are opposite to the threaded rotation direction of the outer surfaces of the threaded rod 402;

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that since the threaded column 502 and the threaded rod 402 are linked by the second pulley group 503, the two threaded columns 502 are linked by the first pulley group 504, so that the two threaded columns 502 rotate together. Since the threaded column 502 is threadedly connected to the threaded tube 501, and the threads at both ends of the threaded column 502 have opposite rotation directions, the two groups of threaded tubes 501 move in opposite directions in the horizontal direction. Since the threads of the threaded column 502 and the threaded rod 402 have opposite rotation directions, the frame 101 moves away in the horizontal direction, thereby realizing the extension operation of the conveyor belt 103, so that the conveyor body 1 has an extension function, so that there is no need to add an additional conveyor body 1 during long-distance transportation, which reduces the cost of use, and can be adapted according to the required distance, which is more convenient to use.

[0029] See also Figure 1 and Figure 2 It can be seen that the threaded plate 403 is symmetrically provided with limiting holes inside, and a limiting rod penetrating the limiting holes is welded inside the vertical plate at the top of the support platform 3. The threaded plate 403 and the support platform 3 form a sliding structure through the limiting rod and the limiting hole, which can play a supporting and limiting role, thereby increasing the stability of the threaded plate 403 during sliding.

[0030] The working principle of the utility model is as follows: when the conveyor with an extension structure is used, the driving motor drives the conveying roller 102 to move, and drives the conveying belt 103 to move through the conveying roller 102, thereby realizing the transportation of coal blocks. When long-distance transportation is required, the rotating motor 401 is started, so that the output end of the rotating motor 401 drives the threaded rod 402 to rotate, and then the threaded plate 403 is moved toward the horizontal direction, and the conveying belt 103 is relatively loosened, and at the same time, the two threaded columns 502 are rotated together under the action of the second pulley group 504 and the first pulley group 503. Since the threaded column 502 is threadedly connected to the threaded cylinder 501, the two groups of threaded cylinders 501 are moved in the opposite direction in the horizontal direction, and then the frame 101 is moved away from the horizontal direction under the action of the roller 8, thereby realizing the extension operation of the conveying belt 103. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
