DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1-9As shown, the drum coal mining machine of the embodiment of the present invention includes a support member 1, a coal mining component 2 and a connecting assembly 3. The coal mining component 2 includes a frame 21 and a mining drum 22. The mining drum 22 is arranged on the frame 21 and is rotatable relative to the frame 21. The frame 21 is detachably arranged on the top surface of the support member 1. The mining drum 22 is used to excavate coal. Specifically, as shown in FIG. Figure 1 As shown, the support member 1 extends in the left-right direction. The frame 21 also extends in the left-right direction. There are two mining drums 22. The first mining drum 22 is located on the top surface of the frame 21 and is rotatable relative to the frame 21. The second mining drum 22 is located on the right end surface of the frame 21 and is rotatable relative to the frame 21.

[0029] Specifically, the mining drum 22 includes a cylinder 221 and a shifting tooth 222. The cylinder 221 is cylindrical. There are multiple shifting teeth 222. The multiple shifting teeth 222 are divided into multiple groups. The multiple groups of shifting teeth 222 are arranged at intervals along the extension direction of the cylinder 221. Each group of shifting teeth 222 includes multiple shifting teeth 222. The multiple shifting teeth 222 are arranged at intervals along the circumference of the cylinder 221.

[0030] The connecting assembly 3 includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is provided on the support member 1 and has a mounting hole 311. The second connecting member 32 is provided on the frame 21 and can be fitted into the mounting hole 311. The second connecting member 32 is detachably connected to the first connecting member 31. Specifically, Figure 5 As shown, there are two first connecting members 31, which are spaced apart in the left-right direction, with one first connecting member 31 being provided at the left end of the support member 1 and the other first connecting member 31 being provided at the right end of the support member 1. The first connecting member 31 has two mounting holes 311, which are spaced apart in the front-to-back direction.

[0031] The second connecting member 32 includes a rod 321 and a limiting member 322. One end of the rod 321 (such as Figure 8 The upper end of the rod 321 shown in FIG) is provided on the bottom surface of the frame 21, and the other end of the rod 321 (as shown in FIG) is provided on the bottom surface of the frame 21. Figure 8 The lower end of the rod 321 shown in the figure passes through the mounting hole 311, and one end of the limiting member 322 is rotatably provided at the other end of the rod 321 and has a first position and a second position. In the first position, the other end of the limiting member 322 is close to the other end of the rod 321 so that the other end of the rod 321 can pass through the mounting hole 311. In the second position, the other end of the limiting member 322 is away from the other end of the rod 321 so that at least a portion of the limiting member 322 can contact the bottom surface of the first connecting member 31.

[0032] Specifically, the second connecting member 32 includes a rod 321 and a limiting member 322. When the frame 21 is separated from the support member 1, the other end of the limiting member 322 is located in the first position to facilitate the rod 321 to detach from the mounting hole 311. When the frame 21 is connected to the support member 1, the other end of the limiting member 322 is first located in the first position to facilitate the other end of the rod 321 to penetrate the mounting hole 311, and then the other end of the limiting member 322 is located in the second position so that at least a portion of the limiting member 322 can contact the bottom surface of the first connecting member 31, so that the rod 321 is not easily detached from the mounting hole 311, thereby firmly connecting the frame 21 and the support member 1. Therefore, the roller mining machine of the embodiment of the present invention is stable during operation. In addition, the second connecting member 32 has a simple structure and is easy to manufacture.

[0033] In the drum coal mining machine of the embodiment of the present invention, the frame 21 is detachably connected to the support 1 through the connecting assembly 3, the first connecting member 31 is provided on the support 1, and the second connecting member 32 is provided on the frame 21, and the first connecting member 31 and the second connecting member 32 are detachably connected. When the mining drum 22 needs to be overhauled, the first connecting member 31 and the second connecting member 32 are separated to separate the frame 21 from the support 1, so as to facilitate the overhaul of the mining drum 22. After the overhaul of the mining drum 22 is completed, the first connecting member 31 and the second connecting member 32 are connected again to install the frame 21 on the support 1, so that the drum mining machine of the embodiment of the present invention can continue to work, and the matching method of the first connecting member 31 and the second connecting member 32 is simple, which saves time, so that the mining drum 22 does not need to be shut down for overhaul, thereby improving the working efficiency and coal mining efficiency of the drum mining machine of the embodiment of the present invention.

[0034] In some embodiments, the limiting member 322 includes an elastic member 3221 and a first clamping member 3222. A mounting groove 3211 is provided on the outer wall surface of the other end of the rod member 321. One end of the first clamping member 3222 is rotatably connected to the inner wall surface of the mounting groove 3211. The elastic member 3221 connects the first clamping member 3222 and the inner wall surface of the mounting groove 3211.

[0035] Specifically, if Figure 9 As shown, the mounting groove 3211 is located at the lower end of the rod 321. There are two mounting grooves 3211, and the two mounting grooves 3211 are symmetrically arranged about the axis direction of the rod 321. There are two limiting members 322, and the two limiting members 322 are arranged in a one-to-one correspondence with the two mounting grooves 3211. The elastic member 3221 and the first clamping member 3222 are arranged in the mounting groove 3211. One end of the first clamping member 3222 is connected to the top surface of the mounting groove 3211, and the other end of the first clamping member 3222 can rotate between a first position and a second position. One end of the elastic member 3221 is connected to the lower end of the rod 321, and the other end of the elastic member 3221 is connected to the side of the first clamping member 3222 near the lower end of the rod 321.

[0036] Specifically, the elastic member 3221 is a spring.

[0037] In the first position, the other end of the first clamping member 3222 is close to the other end of the rod 321, and the elastic member 3221 is compressed, making it easier for the rod 321 to pass through the mounting hole 311. In the second position, the other end of the first clamping member 3222 is away from the other end of the rod 321, and the elastic member 3221 is extended to push the other end of the first clamping member 3222 from the first position to the second position. This allows the side of the first clamping member 3222 facing away from the elastic member 3221 to contact the bottom surface of the first connecting member 31, making it difficult for the rod 321 to disengage from the mounting hole 311, and further tightening the connection between the support member 1 and the frame 21. As a result, the roller mining machine according to the embodiment of the present invention is more stable during operation, further improving work efficiency and coal mining efficiency.

[0038] In some embodiments, the limiting member 322 also includes a second clamping member 3223, and the second clamping member 3223 and the first clamping member 3222 are arranged at intervals in the extension direction of the rod member 321. The second clamping member 3223 is located above the first clamping member 3222, and the second clamping member 3223 is arranged around the outer wall surface of the rod member 321. At least a portion of the second clamping member 3223 can contact the top surface of the first connecting member 31.

[0039] Specifically, if Figure 8 and Figure 9 As shown, the rod 321 extends in the vertical direction, the second clamping member 3223 and the first clamping member 3222 are spaced apart in the vertical direction, and the second clamping member 3223 is located above the first clamping member 3222. When the lower end of the rod 321 passes through the mounting hole 311, the first connecting member 31 is located between the first clamping member 3222 and the second clamping member 3223.

[0040] In some embodiments, the retaining member 322 further includes a side plate 3224, which is disposed at the upper end of the rod 321. The side plate 3224 has a larger cross-sectional area than the rod 321, and the side plate 3224 is connected to the frame 21. The bottom of the frame 21 has a mounting hole 311, which extends in the vertical direction and has a first channel 211 and a second channel 212. The first channel 211 is located above the second channel 212, and the first channel 211 and the second channel 212 are coaxially arranged and connected. The cross-sectional area of ​​the first channel 211 is larger than that of the second channel 212. The side plate 3224 is disposed within the first channel 211, and the rod 321 is disposed within the second channel 212, so that the rod 321 is firmly connected to the frame 21 and is not easily separated from the frame 21.

[0041] In some embodiments, the support member 1 includes a body 11, a clamping plate 12 and a screw 13. The clamping plate 12 is provided on the bottom surface of the body 11, and there are at least two clamping plates 12. At least part of the at least two clamping plates 12 is along the first direction (such as Figure 5 The splints 12 are arranged in a spaced relationship with the front and rear directions shown in FIG. 1 , and the splints 12 are movable in a first direction relative to the body 11. Figure 5 As shown, the bottom surface of the body 11 has a bottom groove 111, and the bottom groove 111 extends along the extension direction of the body 11. There are two bottom grooves 111, and the two bottom grooves 111 are arranged at intervals along the front-to-back direction.

[0042] Specifically, if Figure 1 and 5 As shown, the clamping plate 12 is provided on the bottom surface of the body 11 and extends in the left-right direction. There are two clamping plates 12, which are spaced apart in the front-to-back direction. The two clamping plates 12 are provided in a one-to-one correspondence with the two bottom grooves 111, with the top surfaces of the clamping plates 12 extending into the bottom grooves 111.

[0043] The screw 13 is provided on the bottom surface of the body 11, and the screw 13 moves along a first direction (such as Figure 5 The screw 13 extends in the front-to-back direction as shown, and the screw 13 can rotate about a first direction relative to the body 11. The splint 12 is passed through the screw 13 so that the splint 12 can move on the screw 13 when the screw 13 rotates about the first direction relative to the body 11.

[0044] Specifically, if Figure 1 and 5 As shown, there are two screw rods 13, and the two screw rods 13 are arranged in a one-to-one correspondence with the two bottom grooves 111. The screw rods 13 extend in the front-to-back direction, and the central axes of the two screw rods 13 coincide with each other. The ends of the two screw rods 13 that are away from each other extend out of the side of the body 11.

[0045] The clamping plate 12 in one bottom groove 111 passes through the screw 13 in that bottom groove 111. The clamping plate 12 in the other bottom groove 111 passes through the screw 13 in the other bottom groove 111. The clamping plates 12 and the screw 13 are threadedly engaged. When the screw 13 rotates in the forward and backward direction relative to the body 11, the clamping plates 12 can be driven to move on the screw 13, thereby changing the distance between the two clamping plates 12. The operation is simple.

[0046] In some embodiments, the support member 1 further includes a guide member 14, a bearing (not shown) and a first driving member 15. The guide member 14 is provided on the bottom surface of the body 11, and the guide member 14 and the screw 13 are moved along the second direction (e.g. Figure 1 The guide members 14 extend along the first direction and pass through the clamping plate 12. The clamping plate 12 is movable relative to the guide members 14. Figure 5As shown, there are two guide members 14 , which are spaced apart in the left-right direction, extend in the front-back direction, and pass through the two clamping plates 12 in sequence.

[0047] A bearing is disposed between screw 13 and body 11. A first drive member 15 is connected to screw 13 to drive screw 13 to rotate in a first direction. Specifically, two bearings are provided, one corresponding to each screw 13. The bearings are disposed between screw 13 and body 11 to enable screw 13 to rotate in a forward and backward direction relative to body 11.

[0048] Specifically, there are two first driving members 15, which are arranged in a one-to-one correspondence with the two screws 13. The first driving members 15 are connected to the ends of the screws 13 extending from the body 11 to drive the screws 13 to rotate in the front-to-back direction, thereby causing the clamping plates 12 on the screws 13 to move on the screws 13. Therefore, the roller mining machine according to the embodiment of the present invention is easy to operate when adjusting the distance between the two clamping plates 12.

[0049] In some embodiments, the coal mining component 2 further includes a mounting frame 23, a second driving member 24, and a third driving member 25. The mounting frame 23 is provided on the top surface of the frame 21 and is rotatable relative to the frame 21. The mining drum 22 is provided on the mounting frame 23 and is rotatable relative to the mounting frame 23. Specifically, Figure 1 As shown, there are two mounting brackets 23, one of which is located at the left end of the top surface of the frame 21 and is rotatable relative to the frame 21. The first mining drum 22 is connected to one of the mounting brackets 23. The other mounting bracket 23 is located on the side of the right end of the frame 21 and is rotatable relative to the frame 21. The second mining drum 22 is connected to the other mounting bracket 23.

[0050] The second drive member 24 is connected to the mining drum 22 and is used to drive the mining drum 22 to rotate relative to the mounting frame 23. Specifically, there are two second drive members 24, each corresponding to the two coal mining drums. The second drive members 24 are connected to the coal mining drums to drive the coal mining drums to rotate in a forward and backward direction, thereby achieving coal mining.

[0051] A third driving member 25 is provided on the top surface of the frame 21. The third driving member 25 connects the frame 21 and at least partially the mounting frame 23. The third driving member 25 is used to drive the mounting frame 23 to rotate relative to the frame 21. Specifically, two third driving members 25 are provided on the top surface of the frame 21. One third driving member 25 is connected to one of the mounting frames 23 to drive the mounting frame 23 to rotate relative to the frame 21, thereby rotating the first mining drum 22 relative to the frame 21. The other third driving member 25 is connected to the other mounting frame 23 to drive the other mounting frame 23 to rotate relative to the frame 21, thereby rotating the second mining drum 22 relative to the frame 21.

[0052] Specifically, the second driving member 24 is an electric push rod.

[0053] Specifically, the third driving member 25 drives the mounting frame 23 to adjust the position of the mining drum 22 to facilitate coal mining, and the second driving member 24 drives the mining drum 22 to rotate in the front-rear direction to achieve coal mining.

[0054] In some embodiments, the coal mining component 2 further includes a hanger 26 . The hanger 26 is disposed on the top surface of the frame 21 , and an opening 261 is formed on the hanger 26 .

[0055] Specifically, if Figure 1 As shown, the hanger 26 is provided in the middle of the top surface of the frame 21. When the mining drum 22 needs to be inspected, a lifting rope (not shown) is connected to the opening 261 on the hanger 26. The lifting rope cooperates with a crane (not shown). The crane pulls the frame 21 via the lifting rope, thereby separating the frame 21 from the main body 11. This facilitates the crane to separate the frame 21 from the main body 11.

[0056] In some embodiments, the body 11 has a positioning groove (not shown), and the coal mining component 2 further includes a positioning member 27 . The positioning member 27 is provided on the bottom surface of the frame 21 , and the positioning member 27 cooperates with the positioning groove.

[0057] Specifically, the top surface of the body 11 is provided with two positioning slots extending in the left-right direction, spaced apart in the front-to-back direction. Two positioning members 27 are spaced apart in the front-to-back direction on the bottom surface of the frame 21, extending in the left-to-right direction. The two positioning members 27 correspond to the two positioning slots. When the frame 21 is mounted on the top surface of the body 11, the positioning members 27 cooperate with the positioning slots to ensure a precise and secure installation of the frame 21 on the body 11.

[0058] In some embodiments, the shearer further includes a transport member (not shown) disposed between at least two clamping plates 12 and configured to transport the coal. Specifically, the mining drum 22 rotates forward and backward to mine the coal, and the coal falls onto the transport member, which then transports the coal.

[0059] Specifically, the transport member is disposed between two clamping plates 12. The two clamping plates 12 are movable in the front-to-back direction relative to the body 11 to adjust the distance between the two clamping plates 12. This allows for adaptability to transport members of varying widths, thereby increasing the applicability of the drum shearer of the present invention. Specifically, the width of the transport member refers to its dimension in the front-to-back direction.

[0060] In some embodiments, the support member 1 further includes a protrusion 16 , which is provided on a side of the clamping plate 12 close to the transport member, and the protrusion 16 is detachably connected to the transport member.

[0061] Specifically, there are two protrusions 16, one corresponding to each of the two clamping plates 12. The protrusions 16 are located on the sides of the two clamping plates 12 that are adjacent to each other, and the two protrusions 16 on the two clamping plates 12 are arranged opposite each other. The two protrusions 16 on the two clamping plates 12 clamp the transported object, ensuring that the transported object is securely mounted between the two clamping plates 12.

[0062] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
