The small coal particles and coal slime discharged with the water flow cannot be effectively recycled, and the cross-flow of coal and water underground seriously affects the underground working environment, making it difficult to manage the underground environment.

[0003] In order to solve the problem of resource waste and environmental pollution caused by the inability to effectively recycle and treat the coal-water mixture at the tail of the scraper conveyor on the working face, the published patent number is CN117326363A, and the name is a coal-water treatment device and method for the tail of a scraper conveyor.

[0060] Scraper conveyor is a continuous conveying machine with a flexible traction mechanism, mainly used for transporting coal in coal mining working faces and mining tunnels. Scraper conveyor plays an important role in coal mining and is an indispensable main equipment in modern coal mining technology. It can not only realize the continuous transportation of coal, but also improve coal mining efficiency and reduce production costs. The tail recovery device of the scraper conveyor is a device specially designed to recover the scattered materials at the tail of the scraper conveyor. The main function of the tail recovery device is to collect the scattered materials at the tail of the scraper conveyor to avoid material waste and accumulation. At the same time, it can also keep the conveyor clean and hygienic, and improve the service life of the equipment.

[0061] See also Figure 1 , showing a schematic structural diagram of a coal slime recovery device provided in an embodiment of the present application, comprising:

[0062] The feeding part has two ends, namely a feeding end and a discharging end, and there is a height difference between the feeding end and the discharging end. The feeding end is used to connect with the tail of the scraper conveyor;

[0063] A conveying component 1, which is arranged inside the conveying part along the length direction of the conveying part, and the conveying component 1 connects the feeding end and the discharging end;

[0064] The telescopic head 2 is connected to the discharging end and is also connected to the conveying assembly 1. The telescopic head 2 is used to drive the conveying assembly 1 to rotate;

[0065] The material discharging port 3 is arranged on a side of the telescopic head 2 facing the material feeding part.

[0066] In the above embodiment, the feeding part is the main part of the material conveying, and has a feed end and a discharge end. In the present application, the shape of the feeding part is designed as a "C-type" structure, that is, there is a height difference between the feed end and the discharge end, the feed end is located below the discharge end, and the feed direction and the discharge direction are completely opposite, and the feed end is used to be connected to the tail of the scraper conveyor. The transmission component 1 is arranged inside the feeding part along the length direction of the feeding part, and connects the feed end and the discharge end. The transmission component 1 can be a middle single chain. The telescopic head 2 is connected to the discharge end and is also connected to the transmission component 1, that is, the telescopic head 2 is installed at the discharge end and is connected to the scraper chain of the transmission component 1. The discharge port 3 is arranged on the side of the telescopic head 2 facing the feeding part, that is, the discharge port 3 is opened downward, and the transmission component 1 transports the coal sludge to the inside of the telescopic head 2 and falls due to gravity, and the coal sludge is discharged from the feeding part through the discharge port 3.

[0067] The "C-type" structure of the feeding part changes the transport direction by 180 degrees while lifting the material, and finally returns the material to the upper side of the starting point, so that the present application can be applied to the tail of all types of scraper conveyors. The transmission component 1 selects a scraper chain component with a single chain in use to reduce the running resistance of the chain. The telescopic head 2 is used to achieve chain tensioning, and the lower chain track is an open bottom structure, so that the material transported to the telescopic head 2 can be unloaded from its bottom.

[0068] Furthermore, a coal slime recovery device also includes:

[0069] The telescopic tail 4 is connected to the feeding end and is also connected to the conveying assembly 1 . The telescopic tail 4 is used to cooperate with the telescopic head 2 to drive the conveying assembly 1 to rotate.

[0070] In the above embodiment, the telescopic tail 4 is connected to the feed end of the feeding part, and the conveying component 1 in the feeding part is mounted on the rotating component in the telescopic tail 4 to achieve a change in direction. When the telescopic head 2 drives the conveying component 1 to move, the rotating component in the telescopic tail 4 also rotates synchronously.

[0071] The movement of the conveying assembly 1 is achieved by the cooperation between the telescopic machine tail 4 and the telescopic machine head 2, so that the materials on the conveying assembly 1 can be lifted to the discharge end.

[0072] For further information, see Figure 2 , shows a schematic cross-sectional view of a feeding portion provided in an embodiment of the present application, wherein the feeding portion comprises:

[0073] A first feeding trough 5, which is in the shape of an arc, and one end of the first feeding trough 5 is a feeding end, which is used to connect with the tail of the scraper conveyor and the telescopic tail 4;

[0074] A second feeding trough 6, which is in the shape of an arc, one end of which is connected to the other end of the first feeding trough 5, and the other end of which is a discharge end connected to the telescopic head 2;

[0075] Aggregate assembly, which is arranged at the connection between the first feeding trough 5 and the tail of the scraper conveyor, and is used to collect coal slime;

[0076] A cover plate 8, which is disposed at the openings of the first feed trough 5 and the second feed trough 6, and is used to close the first feed trough 5 and the second feed trough 6;

[0077] The middle plate 9 is arranged inside the trough body of the first material conveying trough 5 and the second material conveying trough 6 , and the middle plate 9 is used for installing the conveying component 1 .

[0078] In the above embodiment, the shape of the first feed trough 5 and the second feed trough 6 are both one-quarter circular arc, that is, the shape of the first feed trough 5 and the second feed trough 6 combined is one-half circular arc, that is, "C-shaped". The aggregate assembly is arranged at the connection between the first feed trough 5 and the tail of the scraper conveyor, and the coal sludge falling from the tail of the scraper conveyor enters the first feed trough 5 through the aggregate assembly. The first feed trough 5 and the second feed trough 6 are both unsealed structures, and the first feed trough 5 and the second feed trough 6 are closed by a detachable cover plate 8. The shape of the cover plate 8 is consistent with the shape of the first feed trough 5 and the second feed trough 6, and is installed on the first feed trough 5 and the second feed trough 6 by bolts. The middle plate 9 is arranged in the middle of the trough body of the first feed trough 5 and the second feed trough 6, dividing the space in the trough body into two parts, and the conveying assembly 1 is installed on both sides of the middle plate 9.

[0079] The "C-type" design enables the first feed trough 5 and the second feed trough 6 to be connected smoothly, ensuring that the material can be continuously and stably transmitted. While lifting the material, the transportation direction changes 180 degrees, so that the coal sludge is recovered from the tail outlet of the scraper conveyor to the conveyor belt of the scraper conveyor. The setting of the aggregate assembly effectively collects the coal sludge, reduces the scattering and accumulation of the coal sludge, and keeps the equipment clean and running efficiently. The closing function of the cover plate 8 not only prevents the leakage of materials and makes the feed trough chain a closed structure, but also the detachable cover plate 8 is easy to replace after wear, which is convenient for the installation of the scraper chain and the maintenance of the equipment, and can effectively extend the service life of the equipment. The middle plate 9 provides a stable support and installation platform for the transmission component 1, ensuring the stability and reliability of the transmission mechanism. There is a little gap between the transmission component 1 and the trough body. On the premise of ensuring that the coal sludge can be smoothly transported to the telescopic head 2, the water contained in the coal sludge can be drained through the gap during transportation, making the separation of coal and water more thorough.

[0080] For further information, see Figure 3, shows a schematic structural diagram of a first feed trough 5 provided in an embodiment of the present application, the first feed trough 5 comprises:

[0081] A first side plate group 51, the first side plate group 51 includes two side plates with a preset distance, and the two side plates form a trough body of the first feed trough 5;

[0082] A first panel 52, the first panel 52 is connected to one side of the first side panel set 51, and the other side of the first side panel set 51 forms an opening, and the length of the first panel 52 is less than the length of the first side panel set 51;

[0083] A first connecting plate 53, which is disposed at one end of the first side plate group 51 and is used to connect to the second material conveying trough 6;

[0084] The second connecting plate 54 is disposed at the other end of the first side plate group 51 , and is used to connect to the telescopic machine tail 4 .

[0085] In the above embodiment, the first side plate group 51 and the first panel 52 constitute a first feed trough 5 with an opening on one side, and the first connecting plate 53 and the second connecting plate 54 are arranged at both ends of the first feed trough 5 for connecting with the second feed trough 6 and the telescopic tail 4. The length of the first panel 52 is less than the length of the first side plate group 51, which means that the trough body is open at one end close to the telescopic tail 4.

[0086] The combination of two side panels and a panel forms a strong and stable trough structure that can withstand the weight and pressure during material transmission. The open input end and smooth connection design ensure that the material can efficiently enter the first feed trough 5 and be smoothly transmitted to the second feed trough 6 through the connecting plate.

[0087] For further information, see Figure 4 and Figure 5 , shows a schematic structural diagram of a second feed trough 6 provided in an embodiment of the present application, the second feed trough 6 comprises:

[0088] A second side plate group 61, the second side plate group 61 includes two side plates with a preset distance, and the two side plates form a trough body of the second material conveying trough 6;

[0089] A second panel 62, the second panel 62 is connected to one side of the second side panel set 61, and the other side of the second side panel set 61 forms an opening;

[0090] A third connecting plate 63, which is disposed at one end of the second side plate group 61 and is used to connect with the telescopic head 2;

[0091] A fourth connecting plate 64, which is disposed at the other end of the second side plate group 61 and is used to connect to the first feed trough 5;

[0092] The reinforcing plate 65 is disposed on the fourth connecting plate 64 , and is used to fix the connection between the first material conveying trough 5 and the second material conveying trough 6 .

[0093] In the above embodiment, the second feed trough 6 is also composed of a second side panel group 61 and a second panel 62. The third connecting plate 63 and the fourth connecting plate 64 are arranged at both ends of the second feed trough 6 for connecting with the first feed trough 5 and the telescopic head 2. The difference from the first feed trough 5 is that the fourth connecting plate 64 is provided with a reinforcing plate 65 for fixing the connection between the first feed trough 5 and the second feed trough 6.

[0094] The connection between the first feed trough 5 and the second feed trough 6 is the midpoint of the arc, which is the stress concentration point. The reinforcement plate 65 is provided here to significantly enhance the structural strength of the connection between the first feed trough 5 and the second feed trough 6, thereby improving the stability and reliability of the entire material transmission system.

[0095] For further information, see Figure 6 , shows a schematic structural diagram of an aggregate assembly provided in an embodiment of the present application, the aggregate assembly comprises:

[0096] A mounting plate 71, which is disposed on a side of the first side plate group 51 facing the tail of the scraper conveyor. The mounting plate 71 is obliquely connected to the first side plate group 51, and is used to be connected to the tail of the scraper conveyor;

[0097] A limit plate 72, which is disposed on a side of the first side plate group 51 away from the tail of the scraper conveyor, and the limit plate 72 is obliquely connected to the first side plate group 51;

[0098] The blocking plate 73 is disposed between the limiting plate 72 and the first side plate group 51 , and is used to block the gap between the limiting plate 72 and the first side plate group 51 .

[0099] In the above embodiment, the mounting plate 71 is arranged on the side of the first side plate group 51 facing the tail of the scraper conveyor, and is connected obliquely to the first side plate group 51, that is, the mounting plate 71 is not tightly fitted to the feeding part, but is tightly connected at the bottom, and there is a preset angle between the tops, which can be determined by the operator, and only needs to meet the actual use requirements. The limit plate 72 is arranged on the side of the first side plate group 51 away from the tail of the scraper conveyor, that is, the side opposite to the mounting plate 71, and is also connected obliquely to the feeding part. Since the limit plate 72 is connected obliquely to the feeding part, a gap between the limit plate 72 and the feeding part will appear below the limit plate 72, and the blocking plate 73 is arranged in the gap.

[0100] See also Figure 8 , shows a schematic diagram of the installation of a coal slime recovery device provided by an embodiment of the present application. Since the mounting plate 71 is tilted on the feed part, when the mounting plate 71 is installed on the tail of the scraper conveyor, the present application as a whole will be tilted toward the direction of the tail of the scraper conveyor, which reduces the possibility of material leakage and transmission interruption, and ensures that the recovered coal slime can be smoothly unloaded to the upper chain of the scraper conveyor. The limit plate 72 is also connected to the feed part at an angle to increase the storage space in the trough body. The blocking plate 73 blocks the lower end of the limit plate 72, ensuring that the material can be smoothly transmitted from the tail of the scraper conveyor to the first feed trough 5, thereby improving the efficiency of material transmission.

[0101] Further, the mounting plate 71 includes:

[0102] The material through hole is provided on the mounting plate 71, and the area of ​​the material through hole is greater than or equal to the area of ​​the opening at the tail of the scraper conveyor.

[0103] In the above embodiment, the material through hole is opened on the mounting plate 71, and the coordination with the tail of the scraper conveyor needs to be considered. The area of ​​the material through hole can be determined by the operator. It is only necessary to ensure that the material can smoothly pass through the material through hole on the mounting plate 71 from the tail of the conveyor.

[0104] The design of the material through hole ensures that the material can be smoothly discharged from the tail of the scraper conveyor to the present application, reducing the risk of material blockage or stagnation, thereby improving the efficiency and stability of material transmission. Due to the close fit between the mounting plate 71 and the tail of the scraper conveyor, the installation process is simpler and faster, and it also helps to reduce maintenance costs and complexity.

[0105] Furthermore, a coal slime recovery device also includes:

[0106] The baffle 10 is arranged on one side of the telescopic tail 4 facing the tail of the scraper conveyor.

[0107] In the above embodiment, the baffle 10 is arranged on the telescopic tail 4 and is also located below the tail opening of the scraper conveyor.

[0108] The baffle 10 is used to prevent the coal slime from falling, and ensure that the material can be smoothly transferred from the tail of the scraper conveyor to the first feeding trough 5 .

[0109] Furthermore, a coal slime recovery device also includes:

[0110] The power unit 11 is connected to the telescopic head 2 and is used to provide power for the telescopic head 2 .

[0111] In the above embodiment, the power unit 11 can be installed at the head of the machine or at the tail of the machine according to the actual size conditions of the mine.

[0112] The design of the power unit 11 provides the telescopic head 2 with power to start the conveying assembly 1, so that the conveying assembly 1 can operate normally to transport coal slime. The design of the detachable power unit 11 allows the shape of the present application to be flexibly changed, sufficient to be applied to mines of different sizes, thereby achieving a wide range of applications.

[0113] Furthermore, a coal slime recovery device also includes:

[0114] The material guiding part 12 is connected with the material discharging port 3 and is used for guiding the material at the material discharging port 3 to the body of the scraper conveyor.

[0115] The pump 13 is arranged inside the feeding part and is used to extract water from the material discharged from the tail of the scraper conveyor.

[0116] In the above embodiment, the material guiding portion 12 is directly connected to the material outlet 3 and may be a material guiding funnel, and the pump 13 is disposed inside the first material delivery trough 5 .

[0117] The setting of the material guide part 12 ensures that the material can enter the scraper conveyor body accurately, avoiding waste and accumulation of materials during the conveying process, thereby improving the overall conveying efficiency. By extracting the moisture in the material through the pump 13, the humidity of the material during the conveying process can be effectively reduced, making the material more suitable for subsequent recycling steps. At the same time, reducing moisture also helps to reduce the wear and failure rate of the equipment and extend the service life of the equipment.

[0118] See also Figure 7 , shows a schematic diagram of the installation of a coal slime recovery device provided by an embodiment of the present application. When in use, the present application uses a coupling to install the mounting plate 71 to the tail of the scraper conveyor. Driven by the power unit 11, the conveying assembly 1 and the scraper chain assembly start to operate. Coal slime and coal water enter the first feed trough 5 through the discharge hole at the tail end of the scraper conveyor. A drainage pump 13 is installed in the first feed trough 5. A large amount of water is first pumped out by the drainage pump 13. Coal slime and granular raw coal are transported along the upper chain path, along the first feed trough 5, and the second feed trough 6 to the telescopic head 2 under the scraping of the scraper chain assembly. When transported to the telescopic head, they are unloaded through the discharge port 3 below it, and the coal slime and granular raw coal are recovered to the upper chain path of the scraper conveyor through the guide unit 12 and transported away.
