[0036] The support mechanism 2 is installed around the conveyor belt 1, and the plowshare 31 is connected to the support mechanism 2 and is located above the conveyor belt 1.

[0037] When the conveyor belt 1 is in operation, the plowshare 31 is used to make the materials on the conveyor belt 1 roll.

[0038] In this embodiment, the support mechanism 2 is installed on both sides of the conveyor belt 1 and spans the conveyor belt 1. The plowshare 31 is connected to the support mechanism 2 and is located above the conveyor belt 1. When the conveyor belt 1 is operating, the plowshare 31 can turn over the material on the conveyor belt 1 so that the bottom of the original material faces upward, which is more convenient for comprehensive cleaning of the coal material and improves the quality of the coal material after cleaning.

[0039] In one of the embodiments, the support mechanism 2 can also be directly installed above the conveyor belt 1, for example, directly connected to the ceiling or connected to the bottom of the conveyor belt 1; there is more than one plowshare 31 above the conveyor belt 1, and the number of plowshares 31 is determined according to the width of the conveyor belt 1 and the shoveling range of each plowshare 31; at the same time, the distance between the plowshare 31 and the conveyor belt 1 is determined according to the thickness of the coal; the plowshare 31 can also be set to a structure that flips up and down relative to the support mechanism 2, so as to flip the coal more fully, facilitate the cleaning of the coal by the cleaning device, and thus improve the quality of the coal after cleaning.

[0040] like Figure 1 , Figure 2 As shown, in one embodiment, the support mechanism 2 includes a support frame 21 and a fixing plate 22;

[0041] The fixing plate 22 is installed on the supporting frame 21 , and the plowshare 31 is connected below the fixing plate 22 .

[0042] In this embodiment, the support frame 21 is fixedly installed on both sides of the conveyor belt 1, the fixed plate 22 is installed above the conveyor belt 1 through the support frame 21, and the plowshare 31 is connected to the fixed plate 22 for shoveling materials on the conveyor belt 1.

[0043] In this embodiment, the support frame 21 includes four L-shaped rods, and every two L-shaped rods form a support member, and the fixed plate 22 is arranged between the two support members; the two sides of the fixed plate 22 can also be respectively connected to the four L-shaped rods, and the connection method can be welding, or two holes penetrating the plane of the fixed plate 22 can be set on both sides of the fixed plate 22, and connected with two support members respectively.

[0044] like Figure 1 , Figure 2 As shown, in one embodiment, the turning mechanism 3 also includes a fixed frame 32, a support rod 33 connected above the fixed frame 32 and at least one connecting rod 34 extending downward from the fixed frame 32, the upper end of the support rod 33 is connected to the supporting mechanism 2, and a plowshare 31 is installed at the lower end of each connecting rod 34.

[0045] In this embodiment, the turning mechanism 3 includes a fixed frame 32, a support rod 33 and a connecting rod 34, wherein the upper end of the support rod 33 is connected to the support mechanism 2, and the lower end is connected to the fixed frame 32, and the fixed frame 32 extends downwardly at least one connecting rod 34, and a plowshare 31 is installed at the lower end of the connecting rod 34.

[0046] The upper end of the connecting rod 34 is connected to the fixing frame 32, and the upper end of the fixing frame 32 is connected to the fixing plate 22 of the supporting structure 2 through the supporting rod 33. The fixing frame 32 is parallel to the fixing plate 22. The setting of the fixing frame 32 simplifies the connecting mechanism, and multiple plowshares 31 can be connected at the bottom. At the same time, it can help the plowshares 31 and the connecting rod 34 to release force and maintain the structural integrity of the turning mechanism 3.

[0047] like Figure 1 , Figure 2 As shown, in one of the embodiments, it also includes a lifting mechanism 4 for driving the material turning mechanism 3 to move up and down. The lifting mechanism 4 is installed on the supporting mechanism 2 and connected to the material turning mechanism 3.

[0048] In this embodiment, the lifting mechanism 4 can drive the turning mechanism 3 to move up and down, and can adjust the height between the plowshare 31 and the conveyor belt 1, so as to turn over coal layers of different thicknesses, thereby improving the maneuverability and flexibility of the device and making it more convenient to inspect and repair the plowshare 31.

[0049] like Figure 1 , Figure 2 As shown, in one embodiment, the lifting mechanism 4 includes a driver 41;

[0050] The driver 41 is installed above the supporting mechanism 2 , and the upper end of the supporting rod 33 is connected to the output end of the driver 41 .

[0051] In this embodiment, the driver 41 in the lifting mechanism 4 is installed above the supporting mechanism 2, and the output end of the driver 41 is connected to the upper end of the supporting rod 33. The driver 41 can drive the supporting rod 33 to move up and down, thereby driving the fixing frame 32, the connecting rod 34 and the plowshare 31 connected to the supporting rod 33, so that the plowshare 31 can move up and down relative to the conveyor belt 1 to turn over coal layers of different thicknesses.

[0052] The driver 41 may be an electric push rod, and the output end of the driver 41 is fixedly connected to the upper end of the support rod 33 by bolts.

[0053] like Figure 1-4 As shown, in one embodiment, the lifting mechanism 4 further includes at least one limiting rod 42 , the lower end of the limiting rod 42 is connected to the fixing frame 32 , the upper end thereof passes through the fixing plate 22 , and a limiting block 43 is further disposed at the upper end of the limiting rod 42 .

[0054] In this embodiment, the lifting mechanism 4 further includes at least one limiting rod 42 mounted on the fixing frame 32, and the upper end of the limiting rod 42 penetrates the fixing plate 22 and is provided with a limiting block 43. When the lifting mechanism 4 drives the material turning mechanism 3 to move up and down, the limiting block 43 can limit the moving distance, and when the support rod 33 moves to the bottom, the limiting block 43 will be blocked by the fixing plate 22, so that the support rod 33 cannot continue to slide downward, and the plowshare 31 cannot continue to move downward, thereby achieving the limitation and protection of the plowshare 31, preventing the plowshare 31 from causing large friction with the conveyor belt 1, which may cause damage to the device.

[0055] In a preferred embodiment, the lifting mechanism 4 includes two limit rods 42, and a limit block 43 is provided at the upper end of each limit rod 42. The two limit rods 42 can not only limit the up and down movement of the turning mechanism 3, but also maintain the relative stability between the turning mechanism 3 and the lifting mechanism 4, thereby preventing problems in the connection between the turning mechanism 3 and the lifting mechanism 4.

[0056] like Figure 1-4 As shown, in another preferred embodiment, the fixed frame 32 is a triangular frame, the turning mechanism 3 includes three plowshares 31, the three tips of the fixed frame 32 are respectively connected to a connecting rod 34, and a plowshare 31 is installed at the lower end of each connecting rod 34.

[0057] In this preferred embodiment, the fixing frame 32 is a triangular frame. The triangle has a certain stability. When the plowshare 31 turns the coal, the fixing frame 32 bears part of the force. The triangular structure makes the fixing frame 32 more stable and not easy to be damaged.

[0058] The tips of the three corners of the fixing frame 32 are respectively connected to a connecting rod 34, and a plowshare 31 is respectively installed at the lower end of each connecting rod 34. The device has three plowshares 31. The middle plowshare 31 contacts the coal faster and turns the coal in the middle of the conveyor belt 1. The other two plowshares 31 are arranged on both sides of the conveyor belt 1 to turn the coal on both sides, so that the coal turning is more uniform and the quality of the coal after cleaning is improved.

[0059] like Figure 4 As shown, in one embodiment, the plowshare 31 includes two symmetrically arranged plow blades, and the two plow blades are connected at an angle to form a connecting space between the two plow blades, and the lower end of the connecting rod 34 is connected in the connecting space.

[0060] In this embodiment, the angle between the two plow blades connected at an angle forms a connecting space, and the lower end of the connecting rod 34 is connected in the connecting space. Specifically, the lower end of the connecting rod 34 is divided into three parts, two of which are respectively connected to the two plow blades, and the other part is connected to the connection between the two plow blades, so that the plow head 31 has a force release effect and is not easily damaged when turning the coal.

[0061] like Figure 1 , 2 In a preferred embodiment, one end of the plow blade away from the connecting rod 34 forms a tip of the plowshare 31 , and the tip of the plowshare 31 extends toward the conveyor belt 1 and is inclined in the opposite direction to the conveying direction of the conveyor belt 1 .

[0062] In this preferred embodiment, the tip of the plowshare 31 faces the opposite direction of the conveying direction of the conveyor belt 1. Specifically, when the conveyor belt 1 is in operation, the coal on the conveyor belt 1 will be brought to the tail end of the plowshare 31 by the inclined plowshare 31, and fall back onto the conveyor belt 1 at the tail end. At this time, the coal at the bottom will be turned to the top, and the coal at the top will be turned to the bottom.

[0063] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0064] like Figure 1-4 As shown, in an optimal embodiment, the coal transport turning device includes a conveyor belt 1, a supporting mechanism 2 and a turning mechanism 3, the turning mechanism 3 includes three plowshares 31, the supporting mechanism 2 is installed on the periphery of the conveyor belt 1, the plowshares 31 are connected to the supporting mechanism 2 and are located above the conveyor belt 1, and when the conveyor belt 1 is operating, the three plowshares 31 are used to roll the material on the conveyor belt 1.

[0065] The supporting mechanism 2 includes a supporting frame 21 and a fixing plate 22. The fixing plate 22 is directly mounted on the supporting frame 21, and the supporting frame 21 spans the left and right sides of the conveyor belt 1 to provide a solid supporting force for the turning mechanism 3. In addition, the device can be directly set on the conveyor belt 1, and there is no need to set up additional equipment to roll and wash the coal, which greatly reduces the cost of the equipment.

[0066] The material turning mechanism 3 also includes a triangular fixed frame 32, a support rod 33 connected above the fixed frame 32 and three connecting rods 34 extending downward from the tip of the fixed frame 32, the support rod 33 is connected to the fixed plate 22, and a plowshare 31 is installed at the lower end of each connecting rod 34. The fixed plate 22 can buffer part of the force of the coal on the plowshare 31, and the triangle has stability. The triangular fixed frame 32 can bear a certain force on the material turning mechanism 3, thereby ensuring the integrity of the material turning mechanism 3 and preventing it from being easily damaged.

[0067] The plow blades include two symmetrically arranged plow blades, which are connected at an angle to form a connecting space. The lower end of the connecting rod 34 is connected in the connecting space, and the lower end of the connecting rod 34 is divided into three parts, two of which are respectively connected to the center points of the two plow blades, and the remaining part is connected to the connection between the two plow blades. The lower end of the connecting rod 34 can make the connection structure between the plow head 31 and the connecting rod 34 have a force release effect, so that the plow head 31 is not easily damaged.

[0068] The end of the plow blade away from the connecting rod 34 forms the tip of the plowshare 31, which faces the conveyor belt 1 and is inclined in the opposite direction of the conveying direction of the conveyor belt 1, so that the coal at the bottom can be turned to the top by the plowshare 31.

[0069] Three plowshares 31 arranged in a triangle are provided on the conveyor belt 1. The middle plowshare 31 first contacts the coal transported on the conveyor belt 1 and turns the coal over. The rear two plowshares 31 are respectively provided on both sides of the conveyor belt 1 to turn the coal over, thereby turning the coal over evenly and comprehensively.

[0070] The device is also provided with a lifting mechanism 4 for driving the turning mechanism 3 to move up and down. The lifting mechanism 4 includes a driver 41. The driver 41 is installed above the supporting mechanism 2, and the upper end of the supporting rod 33 is connected to the output end of the driver 41. The driver 41 can drive the supporting rod 33 to move up and down, thereby driving the fixing frame 32, the connecting rod 34 and the plowshare 31 to move up and down, thereby adjusting the height between the plowshare 31 and the conveyor belt 1, and then turning over coal layers of different thicknesses, thereby improving the maneuverability and flexibility of the device and making it more convenient to inspect and repair the plowshare 31.

[0071] The lifting mechanism 4 also includes two limit rods 42 installed on the fixed frame 32. The upper ends of the two limit rods 42 pass through the fixed plate 22 and are provided with limit blocks 43. When the lifting mechanism 4 drives the turning mechanism 3 to move up and down, the limit blocks 43 can limit the moving distance, thereby protecting the plowshare 31 and preventing damage between the plowshare 31 and the conveyor belt 1.
