[0023] 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.

[0024] like Figure 1 and Figure 2As shown, the coal mine unloading device in this embodiment includes a unloading box 1 and a unloading drive assembly 2. The top of the unloading box 1 has a feed port, and the lower end of the unloading box 1 has a tapered unloading channel 11. The flow cross-sectional area at the upper end of the unloading channel 11 is larger than the flow cross-sectional area at the lower end. The unloading port of the unloading channel 11 is connected to the outside. The unloading drive assembly 2 includes a mounting component 21, a driving member 22, an extrusion hammer 23, and an extrusion rod 24. The mounting component 21 is provided on the unloading box 1, the driving member 22 is connected to the mounting component 21, the extrusion hammer 23 is connected to the output end of the driving member 22, and is located above the outlet of the unloading channel 11. The driving member 22 is used to drive the extrusion hammer 23 to reciprocate along the unloading direction; the extrusion rod 24 is connected to the end face of the extrusion hammer 23 facing the unloading port of the unloading channel 11. The extrusion rod 24 passes through the unloading port of the unloading channel 11 and forms a gap with the inner wall of the unloading port.

[0025] Specifically, the extrusion rod 24 is located at the center of the discharge channel 11. The gap formed between the extrusion rod 24 and the inner wall of the discharge port is an annular gap, which facilitates uniform discharge. Furthermore, the driving member 22 and the extrusion hammer 23 are connected by a fixing rod 25, and the position of the extrusion hammer 23 can be adjusted by the fixing rod 25.

[0026] For example, the driving member 22 may be a hydraulic cylinder, which has high working efficiency and can smoothly drive the extrusion hammer 23 to move.

[0027] When the coal is transported through the coal unloading device in this embodiment, the coal enters the unloading box 1 from the feeding port and falls into the conical unloading channel 11 at the bottom. A conical unloading channel 11 is provided at the bottom of the unloading box 1, which can facilitate the coal to be gathered into the unloading channel 11. The unloading drive assembly 2 is installed on the unloading box 1 through the mounting component 21. When it is necessary to drive the coal gathered in the unloading channel 11 to be transported to the unloading port, the drive assembly drives the extrusion hammer 23 to move back and forth. The extrusion hammer 23 can squeeze and crush the coal to prevent large pieces of coal from blocking the unloading channel 11. At the same time, the extrusion hammer 23 drives the extrusion rod 24 to move back and forth. The extrusion rod 24 can dredge the unloading channel 11, so that the upstream coal can be dredged into the unloading port, which is beneficial to the blockage.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, the blanking box 1 includes an upper box body 12 and a lower box body 13 which are sequentially arranged up and down. The upper box body 12 is a hollow cylinder, and the lower box body 13 is a hollow cone.

[0029] It can be understood that by setting the upper box body 12 as a hollow cylinder, more coal can be accommodated, and setting the lower box body 13 as a hollow cone can facilitate the formation of a tapered discharge channel 11 so that the coal in the upper box body 12 automatically converges to the lower box body 13.

[0030] In this embodiment, the extrusion hammer 23 includes two cones or frustums disposed opposite to each other up and down, and the cross-sectional area of the middle portion of the extrusion hammer 23 is larger than the cross-sectional areas of the two ends.

[0031] The extrusion hammer 23 comprising two cones or truncated cones disposed vertically opposite each other means that the extrusion hammer 23 may comprise two cones or two truncated cones disposed vertically opposite each other. The operating principles of the truncated cones and cones are the same. The cross-sectional area of the middle portion of the extrusion hammer 23 being greater than the cross-sectional area of the ends means that the end surfaces of the two cones or truncated cones with larger areas are disposed opposite each other. The two cones or truncated cones may be formed integrally or separately, without limitation.

[0032] In detail, the side surface of the upper end of the extrusion hammer 23 is a conical surface, which can make the coal above the discharge box 1 flow along the side surface of the upper end of the extrusion hammer 23 to the side surface of the lower end of the extrusion hammer 23 and the inner wall of the discharge box 1. The extrusion hammer 23 can use the side surface of the lower end of the extrusion hammer 23 to squeeze the coal during the descent process; when the extrusion hammer 23 rises, since the upper end side surface of the extrusion hammer 23 is a conical surface, the resistance of the extrusion hammer 23 when rising can be reduced, and the load on the driving part 22 can be reduced.

[0033] In this embodiment, if Figure 2 As shown, the extrusion rod 24 includes a rod body section 241 and a cone tip section 242 connected in sequence, and the rod body section 241 is connected to the extrusion hammer 23.

[0034] It can be understood that by providing the rod body section 241, it is convenient to clear the coal mine in the feeding channel 11, and by providing the cone tip section 242, the resistance when the squeezing rod 24 descends can be reduced, so as to smoothly clear the feeding channel 11.

[0035] In this embodiment, if Figure 2 As shown, the mounting component 21 includes a first connecting portion 211 and a second connecting portion 212, the first connecting portion 211 is connected to the driving member 22; there are multiple second connecting portions 212, and the multiple second connecting portions 212 are evenly spaced along the circumference of the first connecting portion 211, and one end of each second connecting portion 212 is connected to the first connecting portion 211, and the other end is detachably connected to the discharge box 1.

[0036] For example, there may be two, three or four second connection parts 212, etc. The specific number of the second connection parts 212 can be set according to the installation space and installation stability, and is not limited here.

[0037] The first connecting portion 211 is provided to connect the driving member 22, and the plurality of second connecting portions 212 are provided to connect the blanking box 1, so that the second connecting portions 212 provide a stable support for the driving member 22 connected to the first connecting portion 211. The second connecting portions 212 are detachably connected to the blanking box 1, so that the blanking drive assembly 2 can be removed from the blanking box 1 through the second connecting portions 212.

[0038] In this embodiment, if Figure 2 and Figure 3 As shown, the second connecting portion 212 includes a connecting rod 2121, a first guide post 2122, a first elastic member 2123, and a first clamping plate 2124. One end of the connecting rod 2121 is connected to the first connecting portion 211. The first guide post 2122 is provided at the end of the connecting rod 2121 away from the first connecting portion 211 and is slidable relative to the connecting rod 2121 along its length. The first elastic member 2123 is provided on the outer circumference of the first guide post 2122 and is connected to the connecting rod 2121 at one end adjacent to the connecting rod 2121. The first clamping plate 2124 is connected to the end of the first guide post 2122 away from the connecting rod 2121 and to the end of the first elastic member 2123 away from the connecting rod 2121, so that the first clamping plate 2124 elastically abuts against the outer wall of the discharge box 1.

[0039] For example, a guide hole is provided at one end of the connecting rod 2121 facing the first guide post 2122 , and the first guide post 2122 is at least partially slidably connected in the guide hole, so that the first guide post 2122 can slide relative to the connecting rod 2121 .

[0040] In this embodiment, the first elastic member 2123 may be a spring, which can be selected as needed and has low cost.

[0041] Specifically, the first connection portion 211 includes a clamp that is clamped to the outer circumference of the driving member 22, and the second connection portion 212 is connected to the clamp. The connecting rod 2121 of the second connection portion 212 can be connected to the clamp by threaded connection or welded to the clamp.

[0042] The shape of the first clamping plate 2124 matches the shape of the outer wall of the blanking box 1, so that the first clamping plate 2124 fits against the outer wall of the blanking box 1. Furthermore, a first anti-slip pad (not shown) can be provided on the surface where the first clamping plate 2124 fits against the blanking box 1, so that the first clamping plate 2124 increases friction with the blanking box 1 through the first anti-slip pad, thereby improving the reliability of the connection.

[0043] When the material discharge drive assembly 2 needs to be installed, place the material discharge drive assembly 2 in the material discharge box 1, pull the first clamping plate 2124 toward the outside of the circumference of the material discharge box 1 until the first clamping plate 2124 moves to the outer wall of the material discharge box 1, loosen the first clamping plate 2124, and under the elastic force of the first elastic member 2123, drive the first clamping plate 2124 to move toward the inside of the material discharge box 1 until the first clamping plate 2124 abuts against the outer wall of the material discharge box 1. When the first clamping plates 2124 of multiple second connecting parts 212 all abut against the outer wall of the material discharge box 1, the installation is completed.

[0044] In this embodiment, if Figures 2 to 4 As shown, the second connecting part 212 also includes a fixing part 2125, a second guide column 2126, a second clamping plate 2127 and a second elastic part 2128. The fixing part 2125 is connected to the connecting rod 2121; the second guide column 2126 is connected to the fixing part 2125 and can slide along its axial direction relative to the fixing part 2125, and the second guide column 2126 is arranged parallel to the first guide column 2122; the second clamping plate 2127 is arranged at one end of the second guide column 2126 away from the fixing part 2125; the second elastic part 2128 is arranged on the circumferential outside of the second guide column 2126 to drive the second clamping plate 2127 to elastically abut against the inner wall of the discharge box 1.

[0045] In detail, the fixing member 2125 is plate-shaped, one end of the fixing member 2125 is connected to the connecting rod 2121, and a guide hole is provided at the end away from the connecting rod 2121. The second guide column 2126 slides through the guide hole, and when the second clamping plate 2127 moves, the second guide column 2126 is driven to move relative to the guide hole.

[0046] A second anti-slip pad (not shown in the figure) can be provided on the second clamping plate 2127 to increase the friction between the first clamping plate 2124 and the blanking box 1 through the second anti-slip pad, thereby improving the reliability of the connection.

[0047] For example, the second elastic member 2128 may be a spring, which is convenient to select according to needs and has low cost.

[0048] In this embodiment, the second connecting part 212 is set, and under the drive of the second elastic part 2128 of the second connecting part 212, the second clamping plate 2127 is abutted against the discharge box 1 from the inner wall of the discharge box 1. The cooperation between the second clamping plate 2127 and the first clamping plate 2124 is conducive to further improving the firmness of the installation of the discharge drive assembly 2.

[0049] like Figure 1 and Figure 2As shown, the coal mine unloading device in this embodiment also includes a vibration component 3, which includes a first vibration component 31 and a second vibration component 32. The first vibration component 31 is arranged on the inner wall of the unloading box 1; the second vibration component 32 is arranged at the output end of the driving member 22 to drive the second vibration component 32 to move when the driving member 22 is running and drive the unloading box 1 to vibrate through the cooperation of the second vibration component 32 and the first vibration component 31.

[0050] It can be understood that by setting up the vibration component 3, when the driving member 22 moves, the driving member 22 drives the second vibration component 32 to move. When the second vibration component 32 moves, the second vibration component 32 cooperates with the first vibration component 31 to drive the discharge box 1 to vibrate. When the discharge box 1 vibrates, it is beneficial to speed up the discharge efficiency.

[0051] In this embodiment, the first vibration component 31 includes multiple elastic vibration blocks, which are distributed in sequence along the inner wall of the discharge box 1. The distribution direction of the multiple elastic vibration blocks is consistent with the moving direction of the output end of the driving member 22. In the process of the driving member 22 driving the second vibration component 32 to move, the second vibration component 32 collides with the elastic vibration block.

[0052] Specifically, multiple groups of elastic vibration blocks can be provided, evenly spaced along the inner wall of the blanking box 1. A second vibration component 32 is provided for each group of elastic vibration blocks, so that multiple locations of the blanking box 1 have vibration sources, thereby improving the vibration effect. For example, the second vibration component 32 is in the shape of an elastic rod or plate.

[0053] It can be understood that when the driving member 22 is in operation, it drives the second vibrating member 32 to move, and the second vibrating member 32 collides with the elastic vibrating blocks in sequence, causing the blanking box 1 to vibrate.

[0054] like Figure 1 and Figure 2 As shown, the coal mine feeding device in this embodiment further includes a feeding pipe 4 , which is connected to the feeding box 1 , and an inlet of the feeding pipe 4 is connected to a feeding port of the feeding box 1 .

[0055] It can be understood that by providing the discharge pipe 4, the coal can be transported downstream through the discharge pipe 4, so that the coal can be transported in a preset direction.
