Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0046] like Figure 1 As shown, the embodiment of the present application provides a mining roadheader 100 , which is mainly used for mining. The mining roadheader 100 includes a carrying mechanism 110 , a cutting mechanism 120 and a sliding mechanism 130 .

[0047] The carrying mechanism 110 includes a body 111 and a walking assembly 112 disposed below the body 111. The walking assembly 112 adopts a crawler structure, so that mining and excavation can adapt to different terrain conditions, the traveling process is stable, and the body 111 is not easy to bump.

[0048] The cutting mechanism 120 is used to cut rock formations in a mine.

[0049] like Figure 1 and Figure 2 As shown, the cutting mechanism 120 includes a cutting head assembly 121 and a control assembly 122. The control assembly 122 is fixed to the right side of the fuselage 111, and the cutting head assembly 121 extends in front of the fuselage 111. The cutting head assembly 121 is suitable for mining hard rock or harder coal seams, and usually uses a cemented carbide tool with high wear resistance and cutting efficiency; the control assembly 122 controls the cutting head assembly 121 to perform precise cutting.

[0050] The sliding mechanism 130 is connected to the bearing mechanism 110 and the cutting mechanism 120 respectively, and the sliding mechanism 130 drives the cutting mechanism 120 to move along the first direction D1 to adjust the total length of the bearing mechanism 110 and the cutting mechanism 120 in the first direction D1. In this way, the mining roadheader 100 can reduce the total length of the bearing mechanism 110 and the cutting mechanism 120 in the first direction D1 through the sliding mechanism 130 in a mine environment with narrow tunnels and short access roads, reduce the turning radius, improve the turning flexibility and applicability of the mining roadheader 100 in a mine, and improve the excavation efficiency.

[0051] It should be noted that the first direction D1 is the length direction of the mining tunneling machine 100. Figure 1 In the embodiment, the first direction D1 is the left-right direction; the second direction D2 is the width direction of the mining tunneling machine 100. For example, Figure 1 In the embodiment, the first direction D1 is the left-right direction and the front-back direction; the third direction D3 is the height direction of the mining roadheader 100. For example, Figure 1 In the figure, the third direction D3 is the up-down direction. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other. In other figures, the first direction D1, the second direction D2 and the third direction D3 can be adaptively adjusted.

[0052] In some embodiments, the sliding mechanism 130 includes a first connecting component 131 , a second connecting component 132 , and a telescopic component 133 .

[0053] like Figure 1 and Figure 3 As shown, the first connecting component 131 is connected to the carrying mechanism 110; the second connecting component and the first connecting component 131 are spaced apart along the first direction D1, and the second connecting component is connected to the cutting mechanism.

[0054] The first connecting component 131 is fixedly connected to the upper part of the fuselage 111 , and the second connecting component 132 is connected to the lower part of the control component 122 .

[0055] The telescopic assembly 133 connects the first connecting assembly 131 and the second connecting assembly 132 , and drives the second connecting assembly 132 to move along the first direction D1 .

[0056] The telescopic assembly 133 is connected between the first connecting assembly 131 and the second connecting assembly 132 , and the telescopic assembly 133 can move along the first direction D1 .

[0057] Exemplarily, the telescopic assembly 133 includes a plurality of telescopic rods arranged along the second direction D2, one end of the telescopic rod is fixedly connected to the first connecting assembly 131, and the other end is fixedly connected to the second connecting assembly 132. By changing the length of the telescopic rod, the second connecting assembly 132 is moved toward or away from the first connecting assembly 131, thereby moving the cutting head assembly 121 toward or away from the fuselage 111, thereby achieving the purpose of adjusting the total length of the mining tunneling machine 100 in the first direction D1.

[0058] Exemplarily, the telescopic assembly 133 includes a slide rail arranged along the second direction D2 and a slider arranged on the slide rail. The second connecting assembly 132 is fixedly connected to the slider. The slider moves on the slide rail, driving the second connecting assembly 132 to move toward or away from the first connecting assembly 131, thereby causing the cutting head assembly 121 to move toward or away from the fuselage 111, thereby achieving the purpose of adjusting the total length of the mining tunneling machine 100 in the first direction D1.

[0059] In some embodiments, the telescopic assembly 133 includes a first link 1331 , a second link 1332 , a third link 1333 , and a fourth link 1334 .

[0060] The first connecting rod 1331, the second connecting rod 1332, the third connecting rod 1333 and the fourth connecting rod 1334 are connected to form a rectangular structure. Compared with the above telescopic rod solution, such a structure requires synchronous control of multiple telescopic rods, which requires higher control accuracy. If the multiple telescopic rods are not synchronized, it is easy to cause jitter, the center line of the cutting head assembly 121 is offset and cannot be accurately positioned, and the telescopic rods are easy to break and need to be replaced frequently, which increases the cost.

[0061] As for the solution of slide rails and sliders, due to the heavy weight of the cutting mechanism 120, multiple slide rails and sliders need to be set, and the synchronous control of multiple sliders also needs to be considered, which requires high control accuracy. If the multiple sliders are not synchronized, it is easy to cause jitter, the center line of the cutting head assembly 121 is offset, and the problem of inaccurate positioning may occur.

[0062] The rectangular structure of the present application does not have the above-mentioned problem of requiring synchronous control, can drive the cutting mechanism 120 to move more smoothly, and has low control accuracy requirements.

[0063] Two adjacent connecting rods are hinged. Specifically, Figure 3 As shown, the telescopic assembly 133 also includes a first hinge 1335 connecting the first link 1331 and the second link 1332, a second hinge 1336 connecting the second link 1332 and the third link 1333, a third hinge 1337 connecting the third link 1333 and the fourth link 1334, and a fourth hinge 1338 connecting the fourth link 1334 and the first link 1331. The first hinge 1335 is connected to the first connecting assembly 131, and the third hinge 1337 is connected to the second connecting assembly.

[0064] In some embodiments, the sliding mechanism 130 further includes a driving assembly 134 , and the driving assembly 134 includes a first driving member 1341 and a second driving member 1342 .

[0065] like Figure 3 As shown, the first driving member 1341 is connected to the second hinge member 1336 and drives the second hinge member 1336 to move along the second direction D2; the second driving member 1342 is connected to the fourth hinge member 1338 and drives the fourth hinge member 1338 to move along the second direction D2.

[0066] The second hinge 1336 and the fourth hinge 1338 move in opposite directions, so that the first connection assembly 131 moves away from or close to the second connection assembly 132. In this way, by making the speeds of the first hinge 1335 and the second hinge 1336 consistent, the telescopic assembly 133 can be accurately controlled, and the centerline of the cutting head assembly 121 will not deviate, thereby reducing the control requirements.

[0067] like Figure 3 As shown, the telescopic assembly 133 further includes a fixing member 135 , and the fixing member 135 is disposed at a middle position between the first connecting assembly 131 and the second connecting assembly 132 .

[0068] Two movable grooves 1351 arranged along the second direction D2 are provided in the fixing member 135. The second hinge 1336 and the fourth hinge 1338 move in one of the movable grooves 1351 respectively. By setting the movable grooves 1351, the freedom of the second hinge 1336 and the fourth hinge 1338 in the first direction D1 is limited, so that the operation of the telescopic assembly 133 is more stable and smooth.

[0069] By providing two movable grooves 1351 independently of each other, interference between the movable travel of the second hinge 1336 and the movable travel of the fourth hinge 1338 can be avoided.

[0070] In some embodiments, the sliding mechanism 130 further includes a limiting assembly 136 , which is connected to the cutting mechanism 120 and disposed below the control assembly 122 .

[0071] The limiting assembly 136 is fixedly connected to the first hinge 1335 . The limiting assembly 136 is formed with a limiting groove 1362 opened along the first direction D1 . The third hinge 1337 is movably disposed in the limiting groove 1362 .

[0072] like Figure 3 and Figure 4 As shown, a positioning hole 1361 is provided in the limiting assembly 136 , the first hinge 1335 is fixedly connected to the positioning hole 1361 , and the positioning hole 1361 and the limiting groove 1362 are spaced apart along the second direction D2 .

[0073] like Figure 1 , 3 As shown in Figure 4, when the third hinge 1337 moves to the left in the limiting groove 1362, the cutting mechanism 120 moves to the left as a whole, shortening the length of the mining tunneling machine 100; when the third hinge 1337 moves to the right in the limiting groove 1362, the cutting mechanism 120 moves to the right as a whole, lengthening the length of the mining tunneling machine 100.

[0074] It should be understood that the limiting groove 1362 limits the degree of freedom of the third hinge 1337 in the second direction D2, making the movement of the telescopic assembly 133 more stable and smooth. When the driving assembly 134 drives the second hinge 1336 and the fourth hinge 1338 to move, the third hinge 1337 moves synchronously in the limiting groove 1362. The two ends of the limiting groove 1362 limit the travel range of the cutting mechanism 120 relative to the body 111, and also limit the minimum length and maximum length of the mining roadheader 100.

[0075] It should be understood that other mechanisms on the fuselage 111 and the cutting mechanism 120 should be arranged at intervals to avoid interference.

[0076] In some embodiments, the mining tunneling machine 100 further includes a dust blocking mechanism 140 disposed on the supporting mechanism 110 , and the dust blocking mechanism 140 includes an air outlet component 141 and an air exhaust component 142 .

[0077] like Figure 2 and Figure 5 As shown, the dust blocking mechanism 140 is disposed at the front end of the machine body 111 to prevent the dust generated during the excavation process from spreading to the rear of the machine body 111 .

[0078] The air exhaust assembly 142 has an air outlet member 1411. The air outlet member 1411 is in an elongated strip shape and is disposed along the second direction D2. A plurality of air outlets 1413 are disposed below the air outlet member 1411, and the air outlet direction of the air outlets 1413 faces downward.

[0079] The air suction assembly 142 has an air suction member 1421, which is arranged at intervals corresponding to the air outlet direction of the air outlet member 1411. The air suction member 1421 is in a long strip shape and is arranged along the second direction D2. A plurality of air suction ports 1423 are arranged above the air suction member 1421, and the air suction direction of the air suction ports 1423 faces upward.

[0080] The air outlet member 1411 cooperates with the air suction member 1421 so that the gas blown out by the air outlet member 1411 passes through the air flow toward the air suction member 1421 and forms a curtain-like airflow wall arranged along the third direction D3. The curtain-like airflow wall is located at the front end of the supporting mechanism 110.

[0081] In the related art, only a blowing member is usually provided, and the blowing direction of the blowing member is downward or forward, which has a poor dust blocking effect. The present application forms a curtain-like airflow wall by cooperating the air outlet member 1411 and the air suction member 1421, which can generate a stronger airflow to drive the dust to move downward, and prevent the dust from spreading to the rear of the fuselage 111.

[0082] In some embodiments, the lengths of the air outlet member 1411 and the air suction member 1421 are not less than the width of the fuselage 111, thereby expanding the area of ​​the curtain-like airflow and improving the ability to block dust.

[0083] In some embodiments, the dust blocking mechanism 140 also includes a first air pump 1412 and a second air pump 1422. The first air pump 1412 is connected to the air outlet piece 1411 through a pipeline, and the second air pump 1422 is connected to the air outlet piece through a pipeline. The first air pump 1412 and the second air pump 1422 are respectively arranged at the rear of the fuselage 111.

[0084] In some embodiments, the second air pump 1422 can also cooperate with the air duct extending to the excavation working face to complete the dust removal work on the working face.

[0085] In some embodiments, the mining tunneling machine 100 further includes a crushing mechanism 150 disposed on the supporting mechanism 110 , and the crushing mechanism 150 includes a moving component 151 and a crushing component 152 .

[0086] Exemplarily, the moving assembly 151 is a mechanical arm with multiple joints, and the crushing assembly 152 is a crushing hammer. The mechanical arm drives the crushing hammer to move, thereby assisting in crushing large rock masses.

[0087] like Figure 2As shown, the moving assembly 151 includes two mechanical arms, which are arranged at the front end of the fuselage 111 and extend forward, and the breaker hammer is arranged at the end of the mechanical arm.

[0088] In some embodiments, the mining tunneling machine 100 further includes a loading mechanism 160 disposed on the supporting mechanism 110 , and the loading mechanism 160 includes a bucket assembly 161 and an auxiliary collecting assembly 162 .

[0089] like Figure 2 As shown, the bucket assembly 161 is used to load debris, and the auxiliary collection assembly 162 is used to scoop the debris into the bucket.

[0090] The bucket assembly 161 adopts a narrow shovel plate, and the width of the bucket assembly 161 is smaller than the width of the body 111, so as to reduce the size of the mining tunneling machine 100 and improve the flexibility of the mining tunneling machine 100.

[0091] Due to the use of a narrow shovel plate, the auxiliary collection assembly 162 includes two claw members 163, and the two claw members 163 are arranged at intervals along the second direction D2, thereby improving the collection efficiency of the debris.

[0092] The claw member 163 includes a fixed rod 1631 and a movable rod 1632 , wherein the fixed rod 1631 is connected to the outer side of the bucket assembly 161 , and the movable rod 1632 is rotatably connected to the fixed rod 1631 , so as to push the slag into the bucket assembly 161 .

[0093] Specifically, during the lowering or transfer of the mining tunneling machine 100, the movable rod 1632 is retracted inward to both sides of the bucket assembly 161. During excavation and loading of rock debris, the movable rod 1632 is extended outward to expand the collection diameter of the bucket assembly 161 on both sides of the bucket assembly 161 to achieve auxiliary debris loading.

[0094] In some embodiments, the mining roadheader 100 further includes a power mechanism 170 disposed on the supporting mechanism 110 , and the power mechanism 170 includes a first driving source 171 and a second driving source 172 .

[0095] The first driving source 171 and the second driving source 172 are integrated into one place and are arranged at the rear of the body 111 .

[0096] Exemplarily, the first driving source 171 is a diesel engine, and the second driving source 172 is a hydraulic pump. The diesel engine drives the hydraulic pump and provides operating power for the travel assembly 112. The hydraulic pump uses the original hydraulic pipeline to provide hydraulic power for the lowering stage of the whole machine.

[0097] It should be noted that the diesel engine is a temporary power device, and the diesel engine is detachably connected to the fuselage 111. The diesel engine can avoid frequent changes in power supply sites and frequent retracting and releasing of cables, thereby improving the mobility efficiency during the lowering of the entire machine.

[0098] In some embodiments, the fuselage 111 eliminates the traditional cab position and explosion-proof casing, and the mining tunneling machine 100 also includes a non-explosion-proof electrical control box 180. The non-explosion-proof electrical control box 180 is arranged at the front of the fuselage 111 and is integrated with the control component 122 of the cutting mechanism 120, thereby further reducing the overall size of the mining tunneling machine 100 and improving the flexibility of the tunneling machine.

[0099] In some embodiments, the mining tunneling machine 100 further includes a cooling pipe 190, which is arranged along the control component 122, the second power source and other components that need to be cooled, and the surface of the cooling pipe 190 is covered with a PN-type thermoelectric material semiconductor refrigeration sheet.

[0100] The mining roadheader 100 provided in the present application is capable of:

[0101] The sliding mechanism 130 is used to drive the cutting mechanism 120 to move along the length direction of the machine body 111, thereby adjusting the length of the whole machine. Especially in a tunnel with a small transition space, the length of the whole machine and the turning radius can be reduced, thereby improving the flexibility of the mining tunneling machine 100;

[0102] By using the bucket assembly 161 equipped with claws, the width of the whole machine is reduced, the size of the whole machine is reduced, and the flexibility of the equipment is improved;

[0103] By using semiconductor refrigeration technology, components such as coolers are eliminated, the size of the machine body is reduced, and the flexibility of the equipment is improved;

[0104] The multi-jointed mechanical arm is connected with the breaker hammer to break the large rock mass that falls to the ground from the filling body of non-coal mines;

[0105] The air outlet member 1411 and the air exhaust member 1421 cooperate to form a curtain-like airflow in front of the fuselage 111 to prevent the dust on the working surface from spreading to the rear.

[0106] A temporary, detachable diesel engine is used to provide temporary power for the traveling assembly 112, avoiding frequent changes of power supply sites and frequent retraction and deployment of cables during the lowering of the entire machine from the surface to the underground working surface, thereby improving the mobility efficiency during the lowering of the entire machine.
