Description

Technical Field

[0001] This invention relates to the field of belt conveyor tail protection technology, and in particular to a belt conveyor tail safety protection device. Background Technology

[0002] Belt conveyors are important continuous transport machinery that play an indispensable role in the transportation of bulk materials. When transporting coal, large coal blocks need to be crushed. Generally, two belt conveyors are connected to form a height difference and toothed plates are installed to crush the coal blocks. The coal crushing and collection module mainly solves the problems of material splashing and coal slurry dripping at the junction of the conveyor head and tail.

[0003] During use, the coal crushing and collecting module at the tail of the conveyor belt can only crush some of the large coal pieces when coal is falling. Many of the coal pieces do not easily contact the toothed plate, which will cause great wear to the bottom conveyor belt when they fall. It is also difficult to center the coal on the bottom conveyor belt. Therefore, this needs to be improved. Summary of the Invention

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, referring to Figures 1 to 3This is the first embodiment of the present invention, which provides a safety protection device for the tail of a belt conveyor, which can improve the crushing effect and automatic centering effect when coal falls at the tail of the belt conveyor. It includes a conveying component 100, which includes a conveying assembly 101, a protective assembly 102 fixedly mounted on the conveying assembly 101, a support assembly 103 mounted on the conveying assembly 101, and a centering assembly 104 fixedly mounted on the support assembly 103. The conveying assembly 101 is used for conveying coal and consists of two belt conveyors with different joint heights. The protective assembly 102 is used to protect and reduce dust on the coal on the conveying assembly 101. The support assembly 103 is used to support the centering assembly 104 at the bottom of the conveying assembly 101 at the tail of the belt conveyor. A guiding component 200 includes a limiting assembly 201 fixedly mounted on the support assembly 103 and a guiding assembly 204 fixedly mounted on the limiting assembly 103. The classification component 202 on component 201 also includes a toothed wall component 203 fixedly mounted on the limiting component 201, a flow guide component 204 slidably mounted on the limiting component 201, and an elastic component 205 fixedly mounted on the limiting component 201 and the flow guide component 204. The limiting component 201 is used to control the uniformity of coal transported on the bottom conveyor belt. The classification component 202 divides the falling coal into two sides and guides it to the central component 104 so that it can be evenly transported to the bottom conveyor belt. The toothed wall component 203 is used to crush coal blocks and guide them to the classification component 202. The flow guide component 204 is used to guide coal blocks on the top conveyor belt of the conveying component 101 to the toothed wall component 203. The elastic component 205 is used to adjust the guiding angle of the flow guide component 204, which can make the coal blocks guided to the toothed wall component 203 more uniform, thereby achieving a better crushing effect.

[0035] In use, the conveying assembly 101 is used to convey coal. It consists of two belt conveyors with different joint heights. The protection assembly 102 is used to protect and reduce dust on the coal on the conveying assembly 101. The support assembly 103 is used to support the centering assembly 104 at the tail of the bottom belt conveyor on the conveying assembly 101. The limiting assembly 201 is used to control the uniformity of the coal transported on the bottom belt conveyor. The sorting assembly 202 divides the falling coal into two sides and guides it to the centering assembly 104 so that it can be evenly conveyed to the bottom belt conveyor. The toothed wall assembly 203 is used to crush coal lumps and guide them to the sorting assembly 202. The flow guiding assembly 204 is used to guide the coal lumps on the top belt conveyor of the conveying assembly 101 to the toothed wall assembly 203. The elastic assembly 205 is used to adjust the guiding angle of the flow guiding assembly 204, which can make the coal lumps guided to the toothed wall assembly 203 more uniform, thus achieving a better crushing effect.

[0036] In summary, the flow guiding component 204 and the elastic component 205 work together to evenly guide the coal blocks onto the toothed wall component 203 for crushing. The sorting component 202 can then separate the crushed coal blocks to both sides and guide them to the centering component 104. This allows the centering component 104 to evenly spread the coal onto the conveying component 101, thereby improving the coal crushing efficiency and ensuring that the material is evenly spread onto the bottom belt conveyor, preventing the tail of the belt conveyor from being impacted by falling coal and thus improving the protection performance of the belt conveyor tail.

[0037] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a transmission component 100 for a safety protection device at the tail of the conveyor belt, which solves the problem of centering the coal after it falls. It includes a conveying assembly 101 comprising a first conveyor belt 101a and a second conveyor belt 101b. The first conveyor belt 101a is the bottom conveyor belt, and the second conveyor belt 101b is located at the tail side of the first conveyor belt 101a. A support frame 101c is fixedly installed on the second conveyor belt 101b. Since the second conveyor belt 101b needs to form a height difference with the first conveyor belt, the bottom of the second conveyor belt 101b has a support frame 101c to support it.

[0038] Specifically, the protective component 102 includes a cover 102a, and a slot 102b on the cover 102a. Multiple slots 102b are formed on the top of the cover 102a. It also includes a dry fogging device 102c fixedly mounted on the top of the cover 102a at the slot 102b. The top of the cover 102a has a dry fogging device 102c corresponding to the top of its respective slot 102b. Furthermore, it includes air curtains 1 fixedly mounted on both sides of the cover 102a. 02d, the air curtain 102d is used to contain coal particles. It is located on both sides of the cover 102a corresponding to one end of the dry fog equipment 102c. It also includes L-shaped rods 102e fixed on the cover 102a. The L-shaped rods 102e are located on both sides of the cover 102a, and there are multiple L-shaped rods 102e. The L-shaped rods 102e are connected to the second belt conveyor 101b. The L-shaped rods 102e are all fixed to the top of the second belt conveyor 101b.

[0039] Furthermore, the support assembly 103 includes a bottom shell 103a located at the tail of the first belt conveyor 101a, and an opening 103b at the top of the bottom shell 103a. The opening 103b is located at the top of the bottom shell 103a in the conveying direction of the first belt conveyor 101a. It also includes two reinforcing plates 103c fixed on the bottom shell 103a. The two reinforcing plates 103c are fixed to the inner walls on both sides of the bottom shell 103a respectively. The function of the reinforcing plates 103c is to reinforce the support stability of the bottom shell 103a.

[0040] Furthermore, the centering component 104 includes a centering plate 104a fixedly disposed on the top of the bottom shell 103a, and a central groove 104b provided on the centering plate 104a, wherein the central groove 104b is provided at the opening 103b of the centering plate 104a.

[0041] The rest of the structure is the same as in Example 1.

[0042] In operation, coal blocks are transported to conveyor belt 101a via conveyor belt 2 101b. Cover 102a prevents dust during coal drop and air curtain 102d centers the coal particles. Dry fog equipment 102c reduces dust during coal drop. When conveyor belt 2 101b guides the coal to conveyor belt 101a, guide component 200 breaks up the coal blocks and guides them to centering plate 104a. Concentrated trough 104b then evenly guides the coal to the top of conveyor belt 101a.

[0043] In summary, this method can reduce dust caused by coal particles during coal dropping, and can also evenly concentrate the material after coal dropping onto the bottom conveyor belt, thus protecting the conveyor belt. Furthermore, even material distribution can increase its transportation efficiency.

[0044] Example 3, referring to Figures 1-12 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a guide component 200 for the safety protection device at the tail of the conveyor belt, solving the problem of low crushing efficiency when coal falls at the tail of the conveyor belt. It includes a limiting component 201 comprising an equipment shell 201a on the bottom shell 103a, the equipment shell 201a being located at the top of the bottom shell 103a corresponding to the outer wall of the central plate 104a, and the equipment shell 201a having a reserved groove 201b, an arc-shaped groove 201c, and a discharge chute 201d. The reserved groove 201b is located on one side of the second conveyor belt. The equipment housing 201a has arc-shaped grooves 201c on both sides near the reserved groove 201b. The equipment housing 201a has a discharge groove 201d at the guide of the No. 1 belt conveyor 101a. It also includes mounting blocks 201e fixed on the surface of the equipment housing 201a corresponding to the two sides of the discharge groove 201d, a flexible plate 201f fixed on the mounting block 201e, a limiting groove 201g at the bottom of the flexible plate 201f, and an elastic band 201h fixed on both sides of the flexible plate 201f. The elastic band 201h is connected to the equipment housing 201a.

[0045] Specifically, the classification component 202 includes a triangular plate 202a fixedly disposed inside the equipment housing 201a, and the triangular plate 202a is provided with a long surface 202b and a short surface 202c. The long surface 202b is provided on the left side of the top of the triangular plate 202a, and the short surface 202c is provided on the right side of the top of the triangular plate 202a.

[0046] Furthermore, the toothed wall assembly 203 includes a frame 203a fixedly mounted on the equipment housing 201a, the frame 203a being located on one side wall of the long surface 202b of the inner wall of the equipment housing 201a, and a protruding plate 203b slidably mounted on the frame 203a. It also includes a soft pad 203c fixedly mounted on the protruding plate 203b, with the soft pad 203c fixed inside the frame 203a, and a soft frame 203d mounted on the protruding plate 203b. The outer wall of the protruding plate 203b has a soft frame 203d. 3d, the flexible frame 203d abuts against the frame 203a on one side, and also includes a force-bearing plate 203e fixed on the convex plate 203b. The force-bearing plate 203e is located at the end of the convex plate 203b away from the flexible pad 203c. The force-bearing plate 203e is provided with an arc-shaped inclined surface 203f. The force-bearing plate 203e is provided with an arc-shaped inclined surface 203f at the end away from the convex plate 203b. It also includes a conical block 203g fixed on the arc-shaped inclined surface 203f. Several conical blocks 203g are evenly fixed on the arc-shaped inclined surface 203f.

[0047] Furthermore, the flow guiding assembly 204 includes a flow guiding plate 204a and an inclined surface 204b on the flow guiding plate 204a. The inclined surface 204b is provided on one side of the top end of the flow guiding plate 204a. It also includes arc-shaped blocks 204c fixed on both sides of the flow guiding plate 204a. The arc-shaped blocks 204c are located on both sides of the flow guiding plate 204a away from the inclined surface 204b. The arc-shaped blocks 204c slide inside the arc-shaped groove 201c.

[0048] Furthermore, the elastic component 205 includes a hollow rod 205a, a spring 205b fixedly disposed inside the hollow rod 205a, a connecting rod 205c slidably disposed on the hollow rod 205a, the connecting rod 205c being located inside the hollow rod 205a with one end in contact with the spring 205b, a first rotating component 205d fixedly disposed on the hollow rod 205a, and a second rotating component 205e fixedly disposed on the connecting rod 205c, the first rotating component 205d being connected to the equipment housing 201a, and the second rotating component 205e being connected to the guide plate 204a.

[0049] The rest of the structure is the same as in Example 2.

[0050] During operation, when the No. 2 belt conveyor 101b transports coal to the guide component 200, it is guided to the toothed wall assembly 203 via the guide plate 204a. During this process, some coal, due to inertia, will be guided to the toothed wall assembly 203 before reaching the inclined surface 204b, while the remaining coal will be guided to the toothed wall assembly 203 via the inclined surface 204b. The guiding angles of the coal at these two locations are different, resulting in different positions when impacting the toothed wall assembly 203. Furthermore, when there is excessive coal on the guide plate 204a, its weight will exert a downward force on the elastic component 205, primarily acting on the No. 2 rotating component 20. 5e. Connecting rod 205c compresses spring 205b. Rotating components 205d and 205e rotate during this process. Therefore, when the angle of the guide plate 204a changes, its two guiding angles change with the weight, thus uniformly guiding the coal onto the toothed wall assembly 203. The coal mainly impacts the arc-shaped inclined surface 203f of the force plate 203e, and collides with the conical block 203g on the arc-shaped inclined surface 203f, thereby crushing the coal. During this process, the force plate 203e will be compressed by the convex plate 203b, which in turn will compress the soft pad 203c. The force plate 203e will also compress the soft frame 203d, thereby reducing the impact on the equipment housing 201a and minimizing vibration of the guide component 200. Because the coal blocks strike the arc-shaped inclined surface 203f of the force plate 203e, the broken coal blocks will fall to the center of the top of the triangular plate 202a. Since the coal guided by the guide plate 204a has multiple angles, the position of the coal on the force plate 203e is also different, thus ensuring even distribution on the guide triangular plate 202a. The coal is uniform, but the coal mainly directed to the long side 202b is mostly granular, while the short side 202c is mostly coal ash. The coal on the long side 202b and the short side 202c will be directed to the central component 104. After the central component 104 evenly spreads the coal on the No. 1 belt conveyor 101a, it will pass through the limiting groove 201g of the flexible plate 201f. This ensures that the material on the No. 1 belt conveyor 101a is uniform. If a relatively firm coal block is encountered, the flexible plate 201f will pull the elastic belt 201h, so that the material passes through and then the elastic belt 201h and the flexible plate 201f will return to their original position due to their own elasticity.

[0051] In summary, this method can significantly improve the efficiency and uniformity of coal crushing, and the crushed coal can be evenly guided to the bottom conveyor belt.
