DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0024] The utility model provides Figure 1-Figure 5 The centralized control system of the coal mine belt conveyor shown includes a conveying device, a local parameter sensor and a management and control module. The local parameter sensor includes an angle sensor, which is used to monitor the inclination angle of the conveying device. The management and control module includes a remote management control terminal, an Internet of Things system and a cloud server. The remote management control terminal can communicate with the conveying device through the Internet of Things system and the cloud server in turn.

[0025] The remote management control terminal can communicate with the conveying device through the Internet of Things system and the cloud server in turn, and then the user can adjust and control the conveying device through the remote management control terminal, including the conveying height, conveying speed, etc. At the same time, more groups of conveying devices can be set up, and multiple parameters of a single group of conveying devices can be controlled, and multiple groups of conveying devices can be controlled separately to achieve the effect of centralized control. The remote management control terminal can be set as a mobile terminal to improve the convenience of operation.

[0026] At the same time, an angle sensor (not shown in the figure) is provided to monitor the inclination angle of the conveying device, so as to facilitate the control of the conveying device.

[0027] The conveying device includes a frame 1. Considering that during the coal transportation process, a transfer vehicle is needed and the coal is loaded through a belt conveyor, and the bucket of the transfer vehicle has a certain height, the frame 1 is inclined. A conveyor belt 2 is arranged for rotation inside the frame 1. The frame 1 is also provided with a motor, a roller and other structures to realize the rotation and transportation of the conveyor belt 2. The motor, the roller and other structures are all existing common technologies and will not be described in detail here. The conveying speed can be adjusted and controlled through the remote management control terminal.

[0028] In order to increase the friction force on the surface of the conveyor belt 2 and improve the conveying effect, a retaining frame 5 is fixedly connected to the outer ring of the conveyor belt 2. The retaining frame 5 is V-shaped, and multiple retaining frames 5 are provided, and the multiple retaining frames 5 are distributed at equal distances. Both ends of the retaining frame 5 are fixedly connected to the surrounding bars 6. A stacking space is formed between two adjacent retaining frames 5, which can prevent the coal from rolling and sliding even if the conveyor belt 2 is conveyed in an inclined state, especially the granular coal.

[0029] The utility model can prevent the coal material, especially the granular coal material, from rolling and sliding by arranging structures such as the retaining frame 5 and the surrounding strips 6 on the conveyor belt 2, thereby improving the conveying efficiency.

[0030] The downwardly inclined end of the frame 1 is fixedly connected with a loading box 4. The upwardly inclined end of the frame 1 is fixedly connected with a discharge hopper 3. The loading box 4 is used for loading, the conveyor belt 2 is inclined for conveying, and the materials are discharged from the discharge hopper 3.

[0031] Considering that some materials may adhere to the conveyor belt 2 during the conveying process, in order to clean the conveyor belt 2, an elastic strip 7 is fixedly connected to the inner wall of the discharge hopper 3. Two elastic strips 7 are provided, and the two elastic strips 7 correspond to the surrounding strips 6 on both sides of the conveyor belt 2. A round rod 21 is fixedly connected between the two elastic strips 7, and a swing rod 8 is fixedly connected to the round rod 21. A billiard ball 9 for causing the conveyor belt 2 to vibrate is fixedly connected to the end of the swing rod 8 away from the round rod 21. When in use, the shape and structure of the billiard ball 9 can be adjusted according to the width of the conveyor belt 2 to improve the effect of the vibration.

[0032] Specifically, during the process of conveying coal, the conveyor belt 2 will drive the surrounding bars 6 to move synchronously. When the surrounding bars 6 come into contact with the elastic bars 7, the elastic bars 7 will be squeezed to bend downward. As the conveyor belt 2 continues to rotate, the elastic bars 7 will be separated from the squeezing of the surrounding bars 6 and will restore their deformation. The billiard balls 9 will be driven to swing through the round rods 21 and the swinging rods 8. The billiard balls 9 will hit the conveyor belt 2, causing the conveyor belt 2 to vibrate slightly, thereby shaking off the coal adhered to its outer surface, thereby cleaning the conveyor belt 2.

[0033] The utility model provides structures such as elastic strips 7, billiard balls 9 and upper surrounding strips 6 of the conveyor belt 2, so that the position of the conveyor belt 2 inside the discharge hopper 3 is slightly vibrated, and the coal adhered to its outer surface is shaken off, thereby cleaning the conveyor belt 2.

[0034] The conveying device also includes a base 10, the top of which is rotatably connected to a U-shaped frame 11, which is rotatably arranged on one end of the frame body 1 that is tilted downward. The frame body 1 can be rotated on the base 10 through the U-shaped frame 11 to adjust the conveying direction.

[0035] Both sides of the middle section of the frame 1 are rotatably connected with a slide plate 15, and the bottom of the slide plate 15 is slidably connected with a vertical frame 14. A connecting plate 12 is fixedly connected between the bottoms of the two vertical frames 14, and a strip plate 13 is fixedly connected between the connecting plate 12 and the U-shaped frame 11. The strip plate 13 is provided to improve the stability of the overall structure. A lower cross plate 17 is fixedly connected between the middle sections of the two vertical frames 14, and an upper cross plate 16 is fixedly connected between the bottoms of the two slide plates 15. A threaded rod 19 is rotatably connected to the bottom of the upper cross plate 16, and a threaded hole matching the threaded rod 19 is provided on the lower cross plate 17. A driving motor 18 is fixedly connected to the upper surface of the upper cross plate 16, and the threaded rod 19 is fixedly connected to the driving shaft of the driving motor 18.

[0036] Specifically, the driving motor 18 rotates to drive the threaded rod 19 to rotate. Since the lower cross plate 17 is provided with a threaded hole that cooperates with the threaded rod 19, the upper cross plate 16 drives the two slide plates 15 to move up and down, thereby adjusting the inclination angle of the frame 1.

[0037] Furthermore, the drive motor 18 can be controlled via a remote management control terminal.

[0038] In order to facilitate the adjustment of the conveying direction, universal wheels 20 are fixedly connected to both ends of the bottom of the connecting plate 12 .
