[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to solve the problem of low efficiency in dust removal of a large amount of dust generated by a coal mining machine when mining a coal mine in the prior art, the present invention provides a dust removal coal mining machine.

[0028] Please refer to Figures 1 to 4 As shown, the present invention provides a dust removal coal mining machine, including a device body 10, two dust suction structures 20 and a dust collecting structure 30; rocker arms 11 are movably provided on opposite sides of the device body 10 for collecting coal; the two dust suction structures 20 are movably arranged on the device body 10 and are correspondingly connected to the two rocker arms 11, so as to follow the movement of the two rocker arms 11 and absorb the dust generated by the two rocker arms 11 when collecting coal; the dust collecting structure 30 is arranged on the device body 10, and the two dust suction structures 20 are respectively connected to the dust collecting structure 30, so as to collect the dust absorbed by the two dust suction structures 20 and clean it.

[0029] By applying the technical solution of this embodiment, since the dust suction structure 20 is directly connected to the rocker arm 11, the dust generated during the crushing and collection of coal can be immediately absorbed, avoiding the diffusion of dust in the air, and improving the immediacy and efficiency of dust removal. The traditional water mist spraying method often increases the humidity of the work site and reduces visibility, while the dust removal coal mining machine of the present application directly absorbs dust by physical means, reduces the use of water mist, improves the visibility of the operation on site, and thus enhances the safety of the operation. It avoids the use of a large amount of water for dust suppression, reduces the additional moisture of the equipment and coal, reduces the cost and time of subsequent coal drying treatment, and reduces the potential damage to the electrical part of the coal mining machine, thereby solving the problem of low efficiency of dust removal of a large amount of dust generated by the coal mining machine when mining coal in the prior art. In addition, the design of the dust collection structure 30 enables dust to be collected and cleaned in a centralized manner, reducing the difficulty of cleaning and maintenance, and can reduce maintenance costs and downtime in the long run.

[0030] like Figure 1 and Figure 2 As shown, the dust suction structure 20 includes a support arm 21 and a dust suction member 22; the support arm 21 is rotatably connected to the device body 10, and a dust conveying channel 210 for dust flow is provided in the support arm 21 along its extension direction, and one end of the dust conveying channel 210 is connected to the dust collecting structure 30; the dust suction member 22 is provided at one end of the support arm 21 away from the device body 10, and a plurality of dust suction holes 220 are provided on the dust suction member 22, and the plurality of dust suction holes 220 are respectively connected to the other end of the dust conveying channel 210, so that dust flows from the plurality of dust suction holes 220 and flows into the dust collecting structure 30 through the dust conveying channel 210.

[0031] Through the above-mentioned arrangement, the dust collecting member 22 is arranged on the support arm 21, which can be closer to the dust source, that is, the crushing and collection point of the coal, so that the dust collecting structure 20 can capture the generated dust more quickly and effectively, thereby improving the dust treatment efficiency. In addition, the rotatable connection design between the support arm 21 and the device body 10 enables the dust collecting structure 20 to follow the movement trajectory of the rocker arm 11 for adaptive adjustment, and can maintain a good dust capture effect even under the complex geological conditions of the coal mine working face, thereby improving the flexibility and adaptability of the system. At the same time, the design of the dust conveying channel 210 not only ensures that the dust can flow smoothly from the dust collecting hole 220, but also forms a closed conveying system through the connection between the channel and the dust collecting structure 30, thereby reducing the escape of dust during the conveying process and improving the sealing of the entire system and the integrity of the dust treatment.

[0032] Specifically, the dust suction structure 20 also includes a dust suction assembly 23, which is arranged in the support arm 21 and located at the dust suction member 22, and at least part of the dust suction assembly 23 is rotatably arranged so that dust is sucked from the multiple dust suction holes 220 and flows into the dust conveying channel 210. With the above arrangement, the active rotation of the dust suction assembly 23 can generate a stronger suction force, thereby more effectively sucking dust from the multiple dust suction holes 220, and ensuring good dust capture efficiency even when the hardness of the coal seam is high and the amount of dust is large during the crushing process. At the same time, it helps to optimize the flow of dust in the dust conveying channel 210, reduce the deposition of dust in the channel, keep the channel unobstructed, and improve the dust conveying efficiency.

[0033] Specifically, the dust collecting assembly 23 includes a mounting plate 230 and a dust collecting blade 231; the mounting plate 230 is arranged in the support arm 21; the dust collecting blade 231 is connected to a rotating shaft 232, and the dust collecting blade 231 is rotatably arranged on the mounting plate 230 through the rotating shaft 232 and is located at the connection point between the support arm 21 and the dust collecting member 22, so that when the dust collecting blade 231 rotates, dust flows from the plurality of dust collecting holes 220 into the dust conveying channel 210. In this way, the mounting plate 230 is fixed in the support arm 21, ensuring the precise position of the dust collecting blade 231, so that it can be accurately located at the connection point between the support arm 21 and the dust collecting member 22. The dust suction blades 231 are rotatable through the rotating shaft 232, so that the blades can generate strong suction force, and guide the dust sucked by the multiple dust suction holes 220 into the dust conveying channel 210. Compared with the static dust suction method, this active dust suction design significantly improves the dust suction efficiency and capacity, ensuring that the dust can smoothly enter the subsequent dust collection and processing link after being captured. At the same time, the dust suction blades 231 not only help the dust enter the dust conveying channel 210, but also optimize the flow of dust in the dust conveying channel 210, reduce the accumulation and blockage of dust in the dust conveying channel 210, and keep the dust conveying channel 210 unobstructed, thereby improving the operating efficiency of the entire dust removal coal mining machine.

[0034] like Figure 3As shown, the dust collection assembly 23 also includes a driving component 233, which is arranged on one side of the mounting plate 230, and a mounting slot 234 is arranged on the other side of the mounting plate 230. The output shaft of the driving component 233 is inserted into the mounting slot 234, and the rotating shaft 232 of the dust collection blade 231 and the output shaft of the driving component 233 are respectively wound on the transmission belt 235, so that the driving component 233 drives the dust collection blade 231 to rotate. In the above arrangement, the driving component 233 can be a motor or other power source, which can accurately control the rotation speed of the dust collection blade 231, so that it can be dynamically adjusted according to the actual dust concentration and the motion state of the rocker arm 11 during the dust collection process, which not only ensures high-efficiency dust capture, but also avoids energy waste caused by excessive dust collection. The transmission belt 235 is arranged in the mounting slot 234 to prevent the fragments from affecting the transmission belt 235 during mining, and increase the stability of the dust collection blade 231 during operation. At the same time, the design of the mounting slot 234 facilitates the installation of the driving component 233, and also facilitates the daily inspection and maintenance of the transmission belt 235, the dust collecting fan blades 231 and the driving component 233. This modular design reduces the complexity of maintenance and improves the maintainability and reliability of the system.

[0035] Specifically, the dust collecting structure 30 includes a dust collecting box 31 and two exhaust assemblies 32; the dust collecting box 31 is arranged on the device body 10; the two exhaust assemblies 32 are respectively arranged on the dust collecting box 31 and respectively arranged corresponding to the two dust collecting structures 20, at least a part of the exhaust assemblies 32 is connected to the dust conveying channel 210, and at least another part of the exhaust assemblies 32 is connected to the dust collecting box 31, so that the exhaust assemblies 32 can extract the dust in the dust conveying channel 210 into the dust collecting box 31. Through the above arrangement, the exhaust assemblies 32 are directly connected to the dust conveying channel 210, and the dust captured by the dust collecting structure 20 can be quickly extracted into the dust collecting box 31 through the airflow, avoiding the dust from staying in the dust conveying channel 210 and possible re-diffusion, and ensuring the effective collection of dust. The design of the dust collecting box 31 facilitates the centralized cleaning of dust on a regular basis, reduces the complexity and frequency of cleaning, and improves the maintenance efficiency.

[0036] Specifically, the exhaust component 32 includes an exhaust component 320, a first connecting pipe 321 and a second connecting pipe 322; the exhaust component 320 is arranged on the dust box 31; the first connecting pipe 321 and the second connecting pipe 322 are respectively connected to the exhaust component 320, one end of the first connecting pipe 321 extends into the dust conveying channel 210 and is slidably arranged, and one end of the second connecting pipe 322 extends into the dust box 31. The dust box 31 has filtered water, so that the exhaust component 320 draws dust in the dust conveying channel 210 into the dust box 31 and filters it.

[0037] Through the above arrangement, the function of the exhaust component 320 is to generate airflow, and to suck the dust from the dust conveying channel 210 to the dust collecting box 31 through the first connecting pipe 321. This design ensures that the dust can be quickly and effectively transferred from the dust suction structure 20 to the dust collecting box 31, reduces the retention and escape of dust during the transmission process, and improves the efficiency of dust treatment. The first connecting pipe 321 is slidably arranged in the dust conveying channel 210, which means that it can move flexibly following the range of motion of the support arm 21 and the rocker arm 11, ensuring that when the rocker arm 11 collects coal in various directions, the first connecting pipe 321 can still maintain an effective connection with the dust conveying channel 210, and the mechanical movement will not affect the suction of dust. The filtered water in the dust collecting box 31 serves as a dust filtering medium. When the exhaust component 320 draws dust into the dust collecting box 31, the dust will contact with the water, and the viscosity and gravity of the water will be used to effectively precipitate the dust, purify the air, reduce the complexity of dust treatment, and ensure the cleanliness of the discharged air. By timely suction and water filtration, the dust content in the working area is reduced, the working environment of coal miners is improved, the risk of respiratory diseases is reduced, and the safety and comfort of work are improved. In addition, the air extraction component 320 can adjust the air extraction volume according to the actual working state of the dust suction structure 20 to avoid energy waste. At the same time, the water filtration system has lower maintenance costs than other filtration methods, such as filter screens or filter elements, because water can be replaced regularly without frequent replacement of filter components.

[0038] In this embodiment, the air exhaust component 320 is an exhaust fan.

[0039] Specifically, one end of the dust conveying channel 210 close to the dust collecting box 31 has a bent channel 211 set at an angle with the dust conveying channel 210, and one end of the first connecting pipe 321 extends into the dust conveying channel 210 through the bent channel 211. The outer peripheral wall of the first connecting pipe 321 is sealed and connected to the inner wall of the bent channel 211 and the dust conveying channel 210 respectively, so that when the support arm 21 follows the movement of the rocker arm 11, the first connecting pipe 321 slides in the dust conveying channel 210. Through the above-mentioned setting, the sliding connection design of the bent channel 211 and the first connecting pipe 321 enables the first connecting pipe 321 to slide in the dust conveying channel 210, thereby adapting to the position change of the support arm 21 when following the movement of the rocker arm 11, ensuring the effectiveness and continuity of dust suction, and no matter how the rocker arm 11 rotates, the first connecting pipe 321 can maintain a good connection with the dust conveying channel 210, ensuring the smooth transmission of dust. At the same time, the sealed connection between the first connecting pipe 321 and the inner wall of the bending channel 211 and the dust conveying channel 210 effectively prevents the escape of dust during the transmission process, improves the sealing of the system, ensures the efficiency and completeness of dust treatment, and reduces secondary pollution to the working environment.

[0040] In this embodiment, two air outlets 310 are provided at the top of the dust box 31, and filters 311 are provided in both air outlets 310. In this way, the filter 311 can block fine dust particles that are not completely filtered by water, ensuring that the air discharged to the outside is double-filtered, thereby improving the air purification efficiency and quality, and reducing the pollution to the working environment and the surrounding environment. At the same time, the two air outlets 310 can achieve uniform distribution of airflow, prevent uneven airflow or excessive pressure caused by a single air outlet 310, resulting in dust backflow from the dust conveying channel 210 or other parts, and ensure the stability and reliability of the dust removal system.

[0041] In this embodiment, the bottom of the dust box 31 is connected to a drain pipe that is conductively arranged with the dust box 31, so as to discharge the dirt in the dust box 31. In this way, the design of the drain pipe allows the dust and dirt in the dust box 31 to be directly discharged into a pre-set processing system or container, without opening the dust box 31 for cleaning, thereby simplifying the maintenance process and improving the operating efficiency. By regularly discharging dirt through the drain pipe, the accumulation of dust inside the dust box 31 can be avoided, the maintenance time and downtime caused by cleaning the dust can be reduced, and the labor intensity of the maintenance personnel can be reduced, and the labor cost and time cost can be reduced.

[0042] like Figure 2 As shown, the dust collecting part 22 includes a dust collecting hood 221 and a protective hood 222; the dust collecting hood 221 is a conical structure, the dust collecting hood 221 is connected to the support arm 21, and the opening of the dust collecting hood 221 gradually expands in the direction away from the support arm 21; the protective hood 222 is an arc-shaped structure, the protective hood 222 is connected to the end of the dust collecting hood 221 away from the support arm 21, and a plurality of dust collecting holes 220 are respectively arranged on the protective hood 222 at intervals. In the above arrangement, the dust collecting hood 221 and the protective hood 222 are both made of metal. The design of the conical dust collecting hood 221 utilizes the principle of fluid mechanics. When the dust collecting blades 231 rotate to generate airflow, the conical structure can guide the airflow so that in the direction away from the support arm 21, as the opening of the dust collecting hood 221 expands, the airflow speed slows down, thereby enhancing the efficiency of absorbing dust generated during coal mining. The gradually enlarging opening design of the dust hood 221 can cover a wider working area, effectively increase the dust capture range, and ensure that the dust can be effectively sucked in and processed at different stages and locations of coal collection. The arc design of the protective cover 222 is intended to match the shape of the coal mine working surface or the movement trajectory of the equipment, reduce the collision with the mine wall or other obstacles during operation, and at the same time, the arc structure can disperse the impact force, protect the dust suction hole 220 from damage, and improve the stability and durability of the system.

[0043] In this embodiment, the rocker arm 11 and the support arm 21 are connected by a support rod so that the rocker arm 11 and the support arm 21 are relatively movable, so that when the rocker arm 11 swings up and down, the support arm 21 swings up and down with the rocker arm 11.

[0044] In the present application, the specific usage process is as follows: the operator adds an appropriate amount of water to the inside of the dust box 31, and when the roller of the rocker arm 11 mines the coal, the driving component 233 is started, and the motor drives the rotating shaft 232 to rotate through the transmission belt 235, so that the dust suction fan blades 231 rotate, thereby capturing the dust generated when the rocker arm 11 mines the coal, and transporting it to the inside of the dust conveying channel 210. At the same time, when the rocker arm 11 swings up and down, the free end of the support arm 21 can be driven to rotate through the support rod, so that the dust suction assembly 23 can move with the rocker arm 11, and the exhaust component 320 is started to extract the dust inside the dust conveying channel 210 through the first connecting pipe 321, and transport it to the bottom of the dust box 31 through the second connecting pipe 322, so that the dust-containing air is filtered by the water inside the dust box 31, so that the dust is settled at the bottom of the dust box 31, and the filtered air is discharged through the air outlet 310.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0046] The dust removal coal mining machine includes a device body 10, two dust suction structures 20 and a dust collecting structure 30; rocker arms 11 are movably provided on opposite sides of the device body 10 for collecting coal; the two dust suction structures 20 are movably arranged on the device body 10 and are correspondingly connected to the two rocker arms 11, so as to follow the movement of the two rocker arms 11 and absorb the dust generated by the two rocker arms 11 when collecting coal; the dust collecting structure 30 is arranged on the device body 10, and the two dust suction structures 20 are respectively connected to the dust collecting structure 30, so as to collect the dust absorbed by the two dust suction structures 20 and clean it. In this way, since the dust suction structure 20 is directly connected to the rocker arm 11, the dust generated during the crushing and collection of coal can be immediately absorbed, thereby avoiding the diffusion of dust in the air and improving the immediacy and efficiency of dust removal. The traditional water mist spraying method often increases the humidity of the work site and reduces visibility, while the dust removal coal mining machine of the present application directly absorbs dust by physical means, reduces the use of water mist, improves the visibility of the operation on site, and thus enhances the safety of the operation. It avoids the use of a large amount of water for dust suppression, reduces the additional moisture of the equipment and coal, reduces the cost and time of subsequent coal drying, and reduces the potential damage to the electrical part of the coal mining machine, thereby solving the problem of low efficiency of dust removal of a large amount of dust generated by the coal mining machine when mining coal in the prior art. In addition, the design of the dust collection structure 30 enables dust to be collected and cleaned in a centralized manner, reduces the difficulty of cleaning and maintenance, and can reduce maintenance costs and downtime in the long run.
