Description

Technical Field

[0001] The utility model relates to the technical field of coal mine machinery, in particular to a coal mine bin cleaning machine. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. Coal slime refers to a semi-solid substance formed by coal powder containing water. It is a product in the coal production process. Depending on the variety and the formation mechanism, its properties vary greatly, and its availability also varies greatly. There are many types and uses. There is often a lot of coal slime piled up in the mine. The existing method is to manually shovel the coal slime onto the mine car and then directly transport it to the surface. Not only is the labor intensity of manual cleaning high, but the efficiency is low, the time cycle is long, and the cost of cleaning is high. The cleaning machine effectively replaces manual cleaning, greatly reduces the labor intensity, and shortens the coal slime cleaning cycle.

[0003] However, the existing coal mine cleaning machine mud collecting device only has a spiral mud collecting device, which is not only cumbersome to operate, but also affects the mud discharge efficiency.

[0004] For this reason, we propose a coal mine cleaning machine. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] The embodiment of the present application solves the problem of easy clogging of the coal mine cleaning machine by providing a coal mine cleaning machine. When in use, the coal mine cleaning machine can quickly and smoothly extract the coal slime under the mine.

[0024] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0025] Since the coal slime at the bottom of the mine has high viscosity, the cleaning machine is often blocked by peat. The mine is rich in water resources. The water is pressurized and passed into the collection pipe to reduce the viscosity of the peat in the collection pipe and make it easier to extract. The energy of the water is converted into kinetic energy through the turbine to drive the stirring paddle, stirring the peat in the front of the collection pipe, reducing the viscosity of the peat, which is beneficial to the extraction of the cleaning machine.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-Figure 3 A coal mine cleaning machine comprises: a cleaning machine body 1, a plurality of collecting pipes 2 are installed at the bottom of the cleaning machine body 1, the collecting pipes 2 are connected to a plurality of water inlet pipes 3, a plurality of water inlet channels 4 are arranged inside the pipe body of the collecting pipe 2, the plurality of water inlet channels 4 are connected to a power cabin 5, the power cabin 5 is connected to a water outlet channel 6, the end of the water outlet channel 6 is connected to the inner wall of the collecting pipe 2, a turbine 7 is arranged in the power cabin 5, the turbine 7 is connected to a rotating shaft 8, the rotating shaft 8 is rotatably connected to the collecting pipe 2, and a stirring paddle 9 is connected to the bottom of the rotating shaft 8.

[0028] The water flows through the water inlet pipe 3 and the water inlet channel 4 to the power cabin 5, and then enters the collecting pipe 2 through the water outlet channel 6. A turbine 7 is installed in the power cabin 5. Water can drive the turbine 7 to rotate. The turbine 7 drives the stirring paddle 9 to rotate through the rotating shaft 8. The stirring paddle 9 can stir the coal slime in advance. The water discharged into the collecting pipe 2 can dilute the coal slime, which facilitates the movement of the coal slime in the collecting pipe 2 and prevents the cleaning machine from being blocked.

[0029] The power cabin 5 is cylindrical, and the power cabin 5 is arranged opposite to the connecting ports of the water inlet channel 4 and the water outlet channel 6 .

[0030] The power cabin 5 is arranged relative to the connection ports of the water inlet channel 4 and the water outlet channel 6 to increase the impact of the water flow on the turbine 7, improve the utilization rate of the turbine 7 for the water flow, reduce energy loss, and increase the rotation speed of the turbine 7.

[0031] Reference Figure 2 A plurality of water outlets 10 are arranged at the end of the water outlet channel 6 , and the plurality of water outlets 10 are evenly distributed on the same vertical plane. The end of the water outlet channel 6 has an angle with the horizontal plane and the water flow direction is the extension direction of the collecting pipe 2 .

[0032] The water discharged into the collecting pipe 2 can dilute the coal slime, and the multiple water outlets 10 can expand the dilution area of ​​the coal slime. The end of the water outlet channel 6 has an angle with the horizontal plane and the water flow direction is the extension direction of the collecting pipe 2 to prevent the water outlet 10 from being blocked by the coal slime.

[0033] A bearing 11 is provided at the connection between the rotating shaft 8 and the collecting pipe 2 , and the rotating shaft 8 and the collecting pipe 2 are sealed.

[0034] The seal between the rotating shaft 8 and the collecting pipe 2 can prevent water from flowing out from the gap between the rotating shaft 8 and the collecting pipe 2. The setting of the bearing 11 can reduce the friction between the rotating shaft 8 and the collecting pipe 2 and reduce energy consumption.

[0035] A nozzle 12 is provided at the water outlet 10 , and the nozzle 12 is fixedly connected to the collecting pipe 2 .

[0036] The nozzle 12 can improve the spraying effect of water and improve the wetting effect on the coal slime in the collecting pipe 2.

[0037] A support frame 13 is connected to the lower part of the rotating shaft 8 , the support frame 13 is rotatably connected to the rotating shaft 8 , and the support frame 13 is fixedly connected to the warehouse cleaning machine body 1 .

[0038] The bracket can improve the stability of the rotating shaft 8 during rotation, and prevent the rotating shaft 8 from bending and causing the rotating shaft 8 to get stuck and affect the rotation of the stirring paddle 9. The bracket can also wrap the stirring paddle 9 to prevent the stirring paddle 9 from contacting the coal blocks and being damaged.

[0039] During use, high-pressure water enters the water inlet channel through the water inlet pipe outside the collecting pipe, enters the power compartment through the water inlet channel, and is discharged to the water outlet through the water outlet channel. The water flow drives the turbine, and the turbine drives the stirring paddle to rotate through the rotating shaft. The stirring paddle can stir the coal slime in advance. Water discharged into the collecting pipe can dilute the coal slime, facilitate the movement of the coal slime in the collecting pipe, and prevent the cleaning machine from being blocked.

[0040] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. It can convert water energy into kinetic energy, reduce energy output, and improve the clearance effect of equipment.

[0042] 2. It can moisten the coal slime that has entered the collection pipe and reduce its viscosity to prevent the cleaning machine from being blocked.
