Description

Technical Field

[0001] This utility model relates to the field of manganese ore production, and in particular to a funnel unloading device for manganese ore. Background Technology

[0002] When manganese ore is conveyed by a conveyor belt, the processed ore needs to be transferred to a hopper. During the transfer of manganese ore, the amount of ore transported on the conveyor belt varies with production, sometimes more and sometimes less. The unloading process of the hopper is slow, and the unloading speed of the hopper cannot be adjusted in time. When there is a large amount of ore, it accumulates in the hopper and is prone to blockage near the discharge port. When the blockage is severe, the ore may accumulate too high in the hopper, exceeding the hopper's load-bearing capacity, thus causing the hopper to collapse. At the same time, existing hoppers only have a single discharge port on one side. A hopper with a single discharge port can only discharge from one side in a fixed way, which is difficult to adapt to different production needs and cannot meet diverse production requirements. It is easy to cause the ore to concentrate on one side and the flow rate to be uneven. To address these problems, we propose a hopper unloading device for manganese ore. Utility Model Content

[0003] This utility model provides a funnel unloading device for manganese ore, which solves the problem that when a large amount of ore is transported, blockages are easily formed near the unloading port, which may cause the ore to accumulate too high in the funnel and exceed the funnel's bearing capacity; a funnel with a single unloading port can only unload from one side in a fixed manner, which is difficult to adapt to different production needs and easily causes the ore to concentrate on one side.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a funnel unloading device for manganese ore, including a conveyor belt, a plurality of plowshare unloaders on the conveyor belt, supports on both sides of the plowshare unloaders, a funnel on the supports, a side unloading device on one side of the funnel, and a second unloading device at the bottom of the funnel, the second unloading device including two opening and closing hemispherical valves.

[0005] In a preferred embodiment, the plow unloader includes a U-shaped frame with a rotating electro-hydraulic actuator on it. One end of the electro-hydraulic actuator has a plow head with a rotating shaft that is rotatably connected to the conveyor belt.

[0006] In the preferred embodiment, the top of the support is provided with a rectangular frame, the funnel includes a multi-sided funnel, a support frame is provided on the multi-sided funnel, the support frame abuts against the rectangular frame, a side discharge frame is provided on one side of the funnel, and a bottom discharge barrel is provided at the bottom of the funnel, the bottom discharge barrel is a hollow structure.

[0007] In a preferred embodiment, the side unloading device includes an arc-shaped rotating plate and a first motor. One end of the first motor is provided with a main gear, and the main gear is provided with a meshing driven gear. The first motor is mounted on the side unloading frame.

[0008] In a preferred embodiment, the arc-shaped rotating plate includes an arc-shaped baffle, side plates on both sides of the arc-shaped baffle, and rotating sleeves on the side plates. The rotating sleeves are rotatably connected to the side unloading frame, and a gear is installed on one of the rotating sleeves.

[0009] In the preferred embodiment, the second unloading device includes an mounting ring and a bottom ring. Two hemispherical valves are rotatably connected to the bottom ring. Telescopic cylinders are provided on both sides of the mounting ring. A limit strip is provided at one end of the telescopic cylinder, and the limit strip is connected to the two hemispherical valves.

[0010] In the preferred embodiment, the mounting ring is installed on the bottom discharge hopper, the bottom ring is installed at the bottom of the bottom discharge hopper, and the limiting strip is provided with limiting grooves on both sides.

[0011] In a preferred embodiment, the hemispherical valve includes a hemispherical shell, an arc-shaped plate at the top of the hemispherical shell, rotating shafts on both sides of the hemispherical shell, rotating shafts being rotatably connected to a bottom ring, limiting shafts on both sides of the hemispherical shell, the limiting shafts abutting against limiting grooves, and a side plane at the bottom of the limiting shafts.

[0012] In a preferred embodiment, one end of the hemispherical valve is provided with an arc-shaped outer edge, and the bottom surface of the arc-shaped outer edge of one hemispherical valve abuts against the top surface of the arc-shaped outer edge of another hemispherical valve.

[0013] The beneficial effects of this utility model are as follows: When manganese ore needs to be unloaded, the electro-hydraulic actuator of the plow unloader is driven so that one end of the empty plow head abuts against the conveyor belt, causing the ore on the conveyor belt to be diverted to the funnels on both sides. The two boxes with the conveyor belt are respectively placed on one side of the side unloading device and at the bottom of the second unloading device. The first motor of the side unloading device is driven to rotate the main gear, which in turn rotates the driven gear, causing the arc-shaped rotating plate to rotate relative to the side unloading frame, thereby unloading the material. By adjusting the rotation angle of the first motor, the opening size of the arc-shaped rotating plate relative to the side unloading frame is adjusted, thereby regulating the unloading speed of the material.

[0014] The two telescopic cylinders at the top of the second unloading device are driven to move the two limit bars, thereby causing the two hemispherical valves to rotate relative to the bottom unloading bucket and to open and close relative to each other. The displacement distance of the limit bars is controlled by driving the telescopic cylinders to control the opening and closing angle of the two hemispherical valves, thereby adjusting the unloading speed of the material.

[0015] When there is a large amount of ore, the side discharge device and the second discharge device can be opened simultaneously to prevent ore from accumulating in the hopper and forming blockages near the discharge port. This would prevent the ore from piling up too high in the hopper, exceeding its load-bearing capacity and causing the hopper to collapse. When the ore needs to be transported to different processing equipment or storage areas, the ore unloaded from the side discharge device and the second discharge device can be transported to different locations to meet different production needs. Because the side discharge device and the second discharge device disperse the ore flow, the impact force of the ore flowing from a single discharge port is reduced, thus reducing the possibility of ore splashing. At the same time, the even distribution of ore around the discharge port also reduces the probability of ore spilling onto the ground, making the working environment safer and reducing the risk of accidents to operators due to ore splashing or slippery ground. This has significant potential for widespread application. Attached Figure Description

[0026] Example 1:

[0027] like Figure 1-8 The manganese ore unloading device includes a conveyor belt 1 with multiple plowshare unloaders 2 on it. Supports 3 are located on both sides of each plowshare unloader 2, and funnels 4 are mounted on the supports 3. A side unloading device 5 is located on one side of each funnel 4, and a second unloading device 6 is located at the bottom of each funnel 4. The second unloading device 6 includes two opening and closing hemispherical valves 604. With this structure, when manganese ore needs to be unloaded, the electro-hydraulic actuator 201 of the plowshare unloader 2 is driven, causing one end of the empty plowshare head 202 to abut against the conveyor belt 1, diverting the ore on the conveyor belt 1 to the funnels 4 on both sides. Two conveyor boxes are placed on one side of the side unloading device 5 and at the bottom of the second unloading device 6, respectively. The first motor 502 drives the side unloading device 5 to rotate the main gear 503, which in turn rotates the driven gear 504, causing the arc-shaped rotating plate 501 to rotate relative to the side unloading frame 403, so that the material is unloaded. The opening size of the arc-shaped rotating plate 501 relative to the side unloading frame 403 is adjusted by rotating the first motor 502, thereby adjusting the unloading speed of the material.

[0028] The two telescopic cylinders 7 at the top of the second unloading device 6 are driven to move the two limit bars 603, thereby causing the two hemispherical valves 604 to rotate relative to the bottom unloading bucket 404, so that the two hemispherical valves 604 open and close relative to each other. By driving the telescopic cylinders 7 to extend and retract, the displacement distance of the limit bars 603 is controlled, thereby controlling the opening and closing angle of the two hemispherical valves 604, and thus adjusting the unloading speed of the material.

[0029] When there is a large amount of ore, the side discharge device 5 and the second discharge device 6 can be opened simultaneously to prevent ore from accumulating in the hopper and forming blockages near the discharge port. This would prevent the ore from piling up too high in the hopper, exceeding its load-bearing capacity and causing the hopper to collapse. When the ore needs to be transported to different processing equipment or storage areas, the ore unloaded from the side discharge device 5 and the second discharge device 6 is used to transport the ore to different locations to meet different production needs. Because the side discharge device 5 and the second discharge device 6 disperse the ore flow, the impact force of the ore flowing out from a single discharge port is reduced, thereby reducing the possibility of ore splashing. At the same time, the ore is evenly distributed around the discharge port, which also reduces the probability of ore spilling onto the ground, making the working environment safer and reducing the risk of accidents to operators due to ore splashing or slippery ground.

[0030] In a preferred embodiment, the plow unloader 2 includes a U-shaped frame 203, on which a rotating electro-hydraulic actuator 201 is mounted. One end of the electro-hydraulic actuator 201 is equipped with a plow head 202, and the plow head 202 has a rotating shaft that is rotatably connected to the conveyor belt 1. With this structure,

[0031] In a preferred embodiment, the support 3 has a rectangular frame 301 at its top, and the funnel 4 includes a multi-faceted funnel 401 with a support frame 402 abutting against the rectangular frame 301. A side discharge frame 403 is located on one side of the funnel 4, and a bottom discharge bin 404 is located at the bottom of the funnel 4. The bottom discharge bin 404 has a hollow structure. With this structure, both the side discharge frame 403 and the bottom discharge bin 404 are hollow and connected to the funnel 4. The support frame 402 abuts against the support 3 to enhance the overall stability of the structure.

[0032] In a preferred embodiment, the side unloading device 5 includes an arc-shaped rotating plate 501 and a first motor 502. One end of the first motor 502 is equipped with a main gear 503, and the main gear 503 has a meshing driven gear 504. The first motor 502 is mounted on the side unloading frame 403. With this structure, driving the first motor 502 of the side unloading device 5 causes the main gear 503 to rotate, which in turn causes the driven gear 504 to rotate, causing the arc-shaped rotating plate 501 to rotate relative to the side unloading frame 403, thereby unloading the material. By adjusting the rotation angle of the first motor 502, the opening size of the arc-shaped rotating plate 501 relative to the side unloading frame 403 is adjusted, thus regulating the material unloading speed.

[0033] In a preferred embodiment, the arc-shaped turntable 501 includes an arc-shaped baffle 5011, with side plates 5012 on both sides of the baffle 5011. A rotating sleeve 5013 is mounted on each side plate 5012, and the rotating sleeve 5013 is rotatably connected to the side discharge frame 403. A gear 504 is mounted on one of the rotating sleeves 5013. With this structure, when the amount of ore transported on the conveyor belt 1 is small, the side discharge device 5 or the second discharge device 6 can be opened separately, thus saving on the overall structural operating costs.

[0034] In a preferred embodiment, the second unloading device 6 includes a mounting ring 601 and a bottom ring 602. Two hemispherical valves 604 are rotatably connected to the bottom ring 602. Telescopic cylinders 7 are provided on both sides of the mounting ring 601. One end of each telescopic cylinder 7 has a limiting strip 603, which is connected to the two hemispherical valves 604. With this structure, driving the two telescopic cylinders 7 at the top of the second unloading device 6 causes the two limiting strips 603 to move, allowing the limiting shaft 6044 to slide against the limiting groove 6031. This causes the two hemispherical valves 604 to rotate relative to the bottom unloading bucket 404, opening and closing relative to each other, allowing the ore to fall from the bottom unloading bucket 404. By controlling the extension and retraction length of the ends of the telescopic cylinders 7, the displacement distance of the limiting strips 603 is controlled, thereby controlling the opening and closing angles of the two hemispherical valves 604 and adjusting the unloading speed of the material.

[0035] In the preferred embodiment, the mounting ring 601 is mounted on the bottom discharge hopper 404, the bottom ring 602 is mounted on the bottom of the bottom discharge hopper 404, and the limiting strip 603 has limiting grooves 6031 on both sides. With this structure, the telescopic cylinder 7 is mounted on the mounting ring 601, and the hemispherical valve 604 is rotatably connected to the funnel 4 via the rotating shaft 6042.

[0036] In a preferred embodiment, the hemispherical valve 604 includes a hemispherical shell 6041, an arc-shaped plate 6043 at the top of the hemispherical shell 6041, and rotating shafts 6042 on both sides of the hemispherical shell 6041. The rotating shafts 6042 are rotatably connected to the bottom ring 602. Limiting shafts 6044 are provided on both sides of the hemispherical shell 6041, and the limiting shafts 6044 abut against the limiting grooves 6031. The bottom of the limiting shafts 6044 is provided with a side plane 6045. With this structure, the limiting shafts 6044 abut against the limiting grooves 6031, and the limiting strip 603 slides against the side plane 6045. Due to the presence of the side plane 6045, the movement of the limiting strip 603 is prevented from interfering with the hemispherical valve 604.

[0037] In a preferred embodiment, one end of the hemispherical valve 604 is provided with an arc-shaped outer edge 6046, and the bottom surface of the arc-shaped outer edge 6046 of one hemispherical valve 604 abuts against the top surface of the arc-shaped outer edge 6046 of the other hemispherical valve 604. With this structure, the arc-shaped outer edge 6046 of one hemispherical valve 604 abuts against the arc-shaped outer edge 6046 of the other hemispherical valve 604, so that when both hemispherical valves 604 are closed, one arc-shaped outer edge 6046 covers the other arc-shaped outer edge 6046, and the two arc-shaped outer edges 6046 overlap. This further prevents small pieces of ore from falling from the bottom of the second unloading device 6.

That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
