[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-8 As shown, the scraper conveyor for coal mining faces with different dip angles according to this embodiment of the invention includes a scraper conveyor body 1 and a power unit 2. The power unit 2 is located at the tail of the scraper conveyor body 1 and is hinged to the scraper conveyor body 1. The power unit 2 is placed horizontally, and the scraper conveyor body 1 can rotate relative to the power unit 2. The power unit 2 is used to provide power to the scraper conveyor body 1.

[0029] The scraper conveyor of this invention is applicable to coal seam mining faces with different inclination angles. The scraper conveyor body 1 is rotatable relative to the power unit 2, so that the scraper conveyor body 1 can be applied to coal seam mining faces with different inclination angles. The power unit 2 is always kept horizontal, which ensures the lubrication effect of the power unit 2, reduces wear, ensures service life, and facilitates maintenance and inspection.

[0030] Specifically, the power unit 2 includes a motor 21, a coupling 22, and a reducer 23 connected in sequence. The reducer 23 is connected to the scraper conveyor body 1. The rear housing of the scraper conveyor body 1 contains a sprocket shaft assembly 11 and a scraper assembly (not shown). The reducer 23 is connected to the sprocket shaft assembly 11 to drive the sprocket shaft assembly 11 to run, thereby driving the scraper assembly to run.

[0031] Specifically, the scraper conveyor can be supported by the same type and specification of hydraulic support throughout its entire length, which is easier and more convenient than the existing technology that requires the use of three different specifications of hydraulic support.

[0032] Furthermore, the scraper conveyor suitable for coal seam mining faces with different dip angles also includes a first mounting plate 3 and a second mounting plate 4. The first mounting plate 3 and the second mounting plate 4 are hinged together, the power unit 2 is located on the first mounting plate 3, and the tail of the scraper conveyor body 1 is located on the second mounting plate 4.

[0033] Specifically, the first mounting plate 3 and the second mounting plate 4 are hinged together, allowing the scraper conveyor body 1 to rotate relative to the power unit 2. This facilitates the scraper conveyor body 1 to work on coal seam working faces with different inclination angles, improves the applicability of the scraper conveyor, and the method of achieving a rotatable connection between the scraper conveyor body 1 and the power unit 2 is simple.

[0034] Furthermore, the second mounting plate 4 has an elongated hole 41 on its side wall adjacent to the first mounting plate 3, and a connector 42 is movably installed in the elongated hole 41. The connector 42 is used to connect the first mounting plate 3 and the second mounting plate 4.

[0035] Specifically, an elongated hole 41 is located at one end of the second mounting plate 4 adjacent to the first mounting plate 3 and extends along the extension direction of the scraper conveyor body 1. There are two elongated holes 41, which are respectively located on two opposite sides of the second mounting plate 4. The two elongated holes 41 are arranged opposite each other, and each elongated hole 41 is provided with a connector 42 for connecting the first mounting plate 3 and the second mounting plate 4. This ensures a firm connection between the power unit 2 and the scraper conveyor body 1, and also limits the movement of the scraper conveyor body 1 to prevent the scraper conveyor ladder from swinging.

[0036] The second mounting plate 4 can move relative to the first mounting plate 3 along the extension direction of the elongated hole 41, and can also rotate relative to the first mounting plate 3, so that the second mounting plate 4 has two degrees of freedom, which makes it easy to adapt to the angle changes of different working sides.

[0037] Furthermore, the extension direction of the central axis of the power unit 2 is orthogonal to the extension direction of the scraper conveyor body 1.

[0038] Specifically, the power unit 2 is located on the outer side of the tail of the scraper conveyor body 1. During operation, it can be placed in the auxiliary transport roadway to avoid occupying the area of ​​the longwall face, ensuring that the power unit 2 can be placed horizontally, meeting the installation specifications of each component of the power unit 2, ensuring lubrication, and facilitating installation and debugging. In addition, the power unit 2 is relatively heavy, and placing it on the upper level of the auxiliary transport roadway helps prevent the front scraper conveyor body 1 from sliding down.

[0039] Furthermore, the scraper conveyor suitable for coal seam mining faces with different dip angles also includes a transmission belt 5. The transmission belt 5 is located at one end of the power unit 2. The power unit 2 is connected to the tail of the scraper conveyor body 1 through the transmission belt 5. The power unit 2 drives the scraper conveyor body 1 to operate through the transmission belt 5.

[0040] Specifically, the transmission belt 5 connects the reducer 23 and the sprocket shaft assembly 11. The reducer 23 drives the sprocket shaft assembly 11 to rotate via the transmission belt 5. The transmission belt 5 can be a synchronous toothed belt, a belt, etc. The synchronous toothed belt has a higher transmission power than the belt, and it is more efficient and has less torque loss.

[0041] Furthermore, the rotation angle of the scraper conveyor body 1 is 0-80°.

[0042] Specifically, when the rotation angle of the scraper conveyor body 1 is greater than or equal to 80°, the transmission belt 5 is prone to interference with the connection between the first mounting plate 3 and the second mounting plate 4, affecting the normal use of the scraper conveyor.

[0043] Furthermore, the scraper conveyor suitable for coal seam mining faces with different dip angles also includes a tensioning element 6. The power unit 2 has a movable hole 24, which is elongated and extends in the vertical direction. The tensioning element 6 is movably installed in the movable hole 24 and contacts the surface of the transmission belt 5 to adjust the tension of the transmission belt 5.

[0044] Specifically, the tensioning element 6 is movably installed in the movable hole 24 and can move vertically relative to the power unit 2 to adjust the tension of the belt and prevent the excessive weight of the scraper conveyor body 1 from causing excessive tension of the transmission belt 5.

[0045] Furthermore, the tensioning element 6 includes a tensioning wheel 61, a bearing 62, and a connecting shaft 63. The tensioning wheel 61 is located at one end of the connecting shaft 63, and the bearing 62 is located between the tensioning wheel 61 and the connecting shaft 63. The outer circumferential surface of the tensioning wheel 61 is in contact with the surface of the transmission belt 5, and the other end of the connecting shaft 63 is movably installed in the movable hole 24.

[0046] Specifically, the connecting shaft 63 moves up and down within the movable hole 24 to drive the tensioning wheel 61 to move up and down, thereby adjusting the tension of the transmission belt 5. Furthermore, the bearing 62 allows the tensioning wheel 61 to rotate relative to the connecting shaft 63, reducing the friction between the transmission belt 5 and the tensioning wheel 61 during transmission. The tensioning component 6 has a simple structure, is easy to manufacture, and saves costs.

[0047] Furthermore, the first mounting plate 3 is provided with a plurality of first through holes 31, which are arranged at intervals along a first direction, and a first pin 32 is provided in each of the first through holes 31. The second mounting plate 4 is provided with a plurality of second through holes 43, which are arranged at intervals along the extension direction of the scraper conveyor body 1, and a second pin 44 is provided in each of the second through holes 43. Adjacent first pins 32 and second pins 44 are connected by a connecting ring 7.

[0048] Specifically, a plurality of first through holes 31 are provided on the side of the first mounting plate 3 adjacent to the reducer 23 and are spaced apart along the first direction. A plurality of second through holes 43 are provided on the side of the second mounting plate 4 adjacent to the hydraulic support 9 and are spaced apart along the extension direction of the scraper conveyor body 1.

[0049] The first pin 32 and the second pin 44 have the same structure and both have a hole 33 at one end. The connecting ring 7 passes through the hole 33 on the adjacent first pin 32 and second pin 44 to connect the adjacent first pin 32 and second pin 44, thereby limiting the weight of the scraper conveyor body 1 to be entirely applied to the transmission belt 5. Specifically, the connecting ring 7 is made of a material with elasticity and flexibility, which facilitates the connection of adjacent first pin 32 and second pin 44 when there is an angle between the first mounting plate 3 and the second mounting plate 4.

[0050] In some other embodiments, a plurality of first pins 32 are welded to the upper surface of the first mounting plate 3, and the plurality of first pins 32 are spaced apart along a first direction. A plurality of second pins 44 are welded to the upper surface of the second mounting plate 4, and the plurality of second pins 44 are spaced apart along the extension direction of the scraper conveyor body 1.

[0051] Furthermore, the scraper conveyor suitable for coal seam mining faces with different dip angles also includes a connecting lug 8, which can be connected to the first mounting plate 3 through the first through hole 31. The connecting lug 8 can be connected to the second mounting plate 4 through the second through hole 43. The connecting lug 8 is used to install the hydraulic support 9 on the first mounting plate 3 or the second mounting plate 4.

[0052] Specifically, connecting ears 8 can be provided at both the first through hole 31 and the second through hole 43 so that the hydraulic support 9 can be installed on the mounting plate through the connecting ears 8.
