[0002] Coal conveyor belts play a vital role in the coal, electricity, chemical and other industries. They can efficiently transport large amounts of coal and other bulk materials. They can realize truly continuous production and assembly line operations, greatly improving production efficiency. Moreover, coal conveyor belts use automated and intelligent control systems to avoid the risk of accidental injuries to workers. In short, coal conveyor belts, as an efficient, safe, energy-saving and environmentally friendly material conveying equipment, are an important part of the development of modern logistics technology.

[0003] The coal conveyor belt also has a certain service life. If the environment it is in is relatively harsh, or the long-term load exceeds the set value, the coal conveyor belt may crack or break during operation, which will directly lead to the transmission system not being able to work properly and the production equipment being unable to operate, resulting in production shutdowns and delays in production plans. It may also affect product delivery and sales. In addition, coal slag will adhere to the surface of the coal conveyor belt. If it is not cleaned in time, the weight of the coal slag on the outside of the belt will increase, causing the belt load to increase, reducing its service life, and reducing the actual conveying volume, affecting work efficiency. Utility Model Content

Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0023] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a coal conveyor belt tear protection device, including a support frame 1, a conveyor belt 2 for coal transportation is installed on the inner side of the support frame 1, a driving unit 3 is installed on the outer side of the conveyor belt 2 for driving the conveyor belt 2 to rotate, a wind speed detector 9 is installed in the middle of the conveyor belt 2 for detecting the wind speed, a blast unit 10 is installed at the bottom of the conveyor belt 2, an inclined air outlet 11 is opened on the outer side of the blast unit 10, the inclined air outlet 11 is inclined upward, and the air outlet direction of the inclined air outlet 11 is opposite to the movement direction below the conveyor belt 2, so that the relative speed of the two is greater, and a guide plate 13 matched with the inclined air outlet 11 is installed below the conveyor belt 2, and a plurality of brushes 14 are fixedly installed on the side of the guide plate 13 away from the blast unit 10 for cleaning the coal slag on the outer side of the conveyor belt 2.

[0024] In this embodiment, Figure 2As shown, the driving unit 3 drives the conveyor belt 2 to rotate counterclockwise, and the conveyor belt 2 contacts the brush 14. The brush 14 cleans the coal slag adhered to the conveyor belt 2. The blowing unit 10 is powered on and works, and a high-speed airflow blows to the bottom of the conveyor belt 2 to clean the coal slag on the outside of the conveyor belt 2 again. The direction of the airflow is opposite to the movement direction of the bottom of the conveyor belt 2, so the relative speed is greater and the cleaning effect is better.

[0025] Specifically, a control box 4 is fixedly installed on the outer side of the support frame 1 , the drive unit 3 is fixedly installed on the outer side of the support frame 1 , and the wind speed detector 9 is electrically connected to the drive unit 3 through the control box 4 .

[0026] In this embodiment, when there is a crack in the conveyor belt 2, a high-speed airflow passes through the gap and blows toward the wind speed detector 9. The wind speed detector 9 sends an electrical signal to the control box 4. The control box 4 controls the drive unit 3 to cut off the power, and the conveyor belt 2 stops rotating, reminding the staff to repair. An early warning is given at the beginning stage of damage to the conveyor belt 2, which can reduce the possibility of breakage of the conveyor belt 2, shorten the subsequent maintenance time, and reduce losses.

[0027] Specifically, a connecting plate 7 is fixedly installed at the bottom of the support frame 1, and a collecting funnel 8 is fixedly installed at the bottom of the connecting plate 7 to facilitate the collection of coal slag. The bottom of the collecting funnel 8 is connected to the collecting box, and the collecting equipment required for actual production can be selected. This is a relatively mature existing technology and will not be described in detail herein.

[0028] In this embodiment, the high-speed airflow blown out by the blowing unit 10 flows toward the collection box under the guidance of the guide plate 13, driving the coal slag and dust generated during cleaning to flow to the collection box for collection.

[0029] Specifically, the outer side of the guide plate 13 is fixedly installed on the inner side of the connecting plate 7 , and a fixing column 12 is fixedly installed between the blowing unit 10 and the supporting frame 1 .

[0030] Specifically, a support plate 5 is fixedly installed on the inner side of the support frame 1, and the support plate 5 is in contact with the bottom side of the upper part of the conveyor belt 2, thereby reducing the damage of the conveyor belt 2 caused by the coal pressure and extending the service life of the conveyor belt 2. A mounting frame 6 is fixedly installed between the outer side of the wind speed detector 9 and the support frame 1.

[0031] Specifically, a windshield plate 15 is fixedly installed on the periphery of the support frame 1 , and the bottom height of the windshield plate 15 is lower than the bottom height of the conveyor belt 2 .

[0032] In this embodiment, the wind shield 15 is used to isolate the conveyor belt 2 from the outside air to prevent the outside airflow from affecting the detection result of the wind speed detector 9.

[0033] How it works:

[0034] like Figure 2As shown, the driving unit 3 drives the conveyor belt 2 to rotate counterclockwise, and the conveyor belt 2 contacts the brush 14. The brush 14 cleans the coal slag adhered to the conveyor belt 2, and the cleaned coal slag falls into the collection box from the collecting funnel 8. The blowing unit 10 is powered on and works, and a high-speed airflow blows to the bottom of the conveyor belt 2 to clean the coal slag on the outside of the conveyor belt 2 again. The direction of the airflow is opposite to the movement direction of the bottom of the conveyor belt 2, with a greater relative speed and a better cleaning effect. The subsequent airflow flows toward the collection box under the guidance of the guide plate 13, driving the coal slag and dust generated during cleaning to flow to the collection box for collection.

[0035] When there is a crack in the conveyor belt 2, a high-speed airflow passes through the gap and blows toward the wind speed detector 9. The wind speed detector 9 sends an electrical signal to the control box 4. The control box 4 controls the drive unit 3 to cut off the power, and the conveyor belt 2 stops rotating, reminding the staff to repair. An early warning is given at the beginning stage of damage to the conveyor belt 2, which can reduce the possibility of breakage of the conveyor belt 2, shorten the subsequent maintenance time, and reduce losses.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
