Description

Technical Field

[0001] The present application relates to the field of ore mining equipment, and in particular to an ore conveying device with bidirectional feeding of a lowering chute. Background Art

[0002] Ore refers to stones containing some valuable minerals taken from mines. After being crushed, ground and processed step by step, the ore can be used in engineering fields such as metal mining, metallurgical industry, chemical industry, construction industry, cement industry and sand and gravel industry.

[0003] Ore is usually mined in mines. During ore mining operations, in order to facilitate the transportation of ore, ore conveying equipment is needed to transport the mined ore from the mining site to the outside.

[0004] At present, most of the existing ore transportation devices are composed of conveyors and discharge chutes. Both conveyors and discharge chutes are installed on the mine. One end of the conveyor is located at the ore mining position, and the other end of the conveyor is located above the discharge chute. The discharge port of the discharge chute is located above the mine car. During the ore mining process, the staff first loads the ore onto the conveyor, then uses the conveyor to transport the ore to the discharge chute, and then slides into the transport vehicle through the discharge chute.

[0005] With respect to the above-mentioned related technologies, the inventors found that in the process of loading the ore, as the ore is continuously transported, the ore loading position will continue to move forward and become farther and farther away from the conveyor. The ore needs to be transferred for a certain distance before it can be transported to the conveyor. However, the conveyor is difficult to adapt to the advancement of the ore loading position, resulting in the defect that the ore loading is more laborious. Summary of the invention

[0006] In order to alleviate the problem that the conveyor is difficult to adapt to the advancement of the ore feeding position, resulting in more laborious ore feeding, the present application provides an ore conveying device with bidirectional feeding of a feeding chute.

[0007] The present application provides an ore conveying device with bidirectional feeding of a feeding chute, which adopts the following technical solution:

[0009] By adopting the above technical solution, when the ore is transported, the adjustment mechanism is used to drive the mobile frame to move, which can drive the second conveyor to move, thereby realizing automatic adjustment of the position of the second conveyor, so that the second conveyor can move as the ore feeding position changes, thereby making it easier for the staff to feed the ore.

[0011] By adopting the above technical solution, when the position of the second conveyor needs to be adjusted, first start the cylinder to drive the locking block to be inserted into one of the locking holes, and then start the first hydraulic cylinder to drive the movable frame to move, thereby adjusting the position of the second conveyor.

[0012] Preferably, a movable plate is slidably connected to the frame, and the movable plate slides along the length direction of the frame. The mobile frame is rotatably connected to the movable plate, and the rotation axis of the mobile frame is located near the discharge port of the second conveyor. A rotating mechanism is provided on the movable plate, and the rotating mechanism is connected to the mobile frame to drive the mobile frame to rotate.

[0013] By adopting the above technical solution, utilizing the rotation setting of the mobile frame, starting the rotation mechanism, and utilizing the rotation mechanism to drive the mobile frame to rotate, the second conveyor can be driven to rotate, so that the loading end of the second conveyor can be freely rotated to other positions, thereby being able to accommodate more loading positions.

[0015] By adopting the above technical solution, the screening plate is sealed on the feeding port of the first discharge pipe. After the ore enters the chute body from the feeding port, it will first fall on the screening plate. Under the screening of the screening plate, the fine ore will enter the first discharge pipe and then be discharged, and the coarse ore will enter the second discharge pipe and then be discharged. First, the fine ore and the coarse ore are discharged separately, and then enter different mine cars respectively, so as to realize the two-way feeding of the discharge chute.

At this time, the screening plate covers the inlet position of the second discharge pipe under the action of its own gravity, and then the first conveyor continues to transport the ore. The ore will enter the chute body from the first discharge pipe and then fall on the screening plate.

Each group of locking blocks 430 includes a plurality of locking holes, and the plurality of locking holes are arranged at intervals along the length direction of the movable frame 200, and the locking block 430 can be inserted into one of the locking holes corresponding to itself. During the ore mining and transportation process, when the ore loading position moves inward due to the continuous mining and transportation of the ore, first start the two cylinders 420, and use the two cylinders 420 to drive the connected locking blocks 430 to be inserted into one of the locking blocks 430, and then start the two cylinders 420 to drive the mobile frame 200 to move, so that the mobile frame 200 drives the second conveyor 210 to move forward a certain distance, and then the ore can continue to be loaded, realizing the automatic adjustment of the position of the second conveyor 210, thereby improving the flexibility of ore loading.

[0043] Reference Figure 2 and Figure 3 In order to further improve the flexibility of the use of the second conveyor 210, the mobile frame 200 is rotatably connected to the mobile plate 220, and the mobile plate 220 is rotatably connected with a rotating rod 230, the rotating rod 230 is vertically arranged, and the mobile frame 200 is fixedly connected to the rotating rod 230.

[0044] Reference Figure 4 , Figure 5 and Figure 6The chute body 300 includes a feed pipe 310, a first discharge pipe 320 and a second discharge pipe 330, which are integrally formed and connected to each other. The feed pipe 310, the first discharge pipe 320 and the second discharge pipe 330 are spaced apart with the axis of the center of gravity of the chute body 300 as the center of the circle. A screening plate 340 is hinged in the chute body 300, and the screening plate 340 blocks the feed port of the first discharge pipe 320 under the action of its own gravity. The chute body 300 is rotatably connected to the support frame 600. The chute body 300 rotates along its own central axis. A second motor 610 is installed on the support frame 600. The second motor 610 is fixedly connected to the chute body 300. The second motor 610 is used to drive the chute body 300 to rotate. When the second discharge pipe 330 rotates to the position of the original first discharge pipe 320, the screening plate 340 covers the inlet position of the second discharge pipe 330 under the action of its own gravity, and at this time, the first discharge pipe 320 rotates to the position of the original feed pipe 310.

[0045] During the use of the screening plate 340, in order to prevent the ore from getting stuck on the screen holes of the screening plate 340 and blocking the screen holes, during the use of the chute body 300, the second motor 610 is periodically started, and the second motor 610 is used to drive the chute body 300 to rotate, so that the first discharge pipe 320 rotates to the position of the original feed pipe 310, and the second discharge pipe 330 rotates to the position of the original first discharge pipe 320. At this time, the screening plate 340 covers the second discharge pipe 330 under the action of its own gravity. 30, and then the first conveyor 110 continues to convey the ore, the ore will enter the chute body 300 from the first discharge pipe 320, and then fall on the screen plate 340, while knocking down the ore stuck on the screen plate 340, the fine ore will be discharged from the second discharge pipe 330, and at the same time, the coarse ore will be discharged from the feed pipe 310. The chute body 300 is repeatedly driven to rotate, which can effectively reduce the possibility of the screen plate 340 being blocked, thereby ensuring continuous two-way feeding of the discharge chute.

[0046] Reference Figure 4 and Figure 7 In order to maintain the first conveyor 110 conveying ore when adjusting the unloading chute, a storage hopper 700 is fixedly connected to the frame 100, a discharge port is opened at the bottom of the storage hopper 700, and an opening and closing mechanism 710 is installed on the storage hopper 700.

The two second hydraulic cylinders 712 are respectively located at opposite sides of the storage hopper 700. The two second hydraulic cylinders 712 are collinear with the hinge axis of the storage hopper 700. The piston rod of each second hydraulic cylinder 712 is hinged to the side wall of the blocking plate 711. Before driving the chute body 300 to rotate, the two second hydraulic cylinders 712 are first started, and the blocking plate 711 is driven to rotate by the second hydraulic cylinders 712, so that the blocking plate 711 blocks the discharge port of the storage hopper 700. The ore transported by the first conveyor 110 can be temporarily stored in the storage hopper 700, and then the chute body 300 is driven to rotate, so that the feeding and discharging of the chute body 300 can be adjusted without affecting the ore transportation efficiency, and then the discharge port of the processing box is opened, so that the chute body 300 can continue to guide the ore.

[0048] Reference Figure 5 and Figure 8 , a dredging mechanism 800 is installed in both the feed pipe 310 and the first discharge pipe 320. In this embodiment, the dredging mechanism 800 on the feed pipe 310 is taken as an example. Each group of dredging mechanisms 800 includes a power part 810. In this embodiment, the power part 810 is a first electric push cylinder 811, which is fixedly connected in the feed pipe 310. The first electric push cylinder 811 is arranged along the length direction of the feed pipe 310. A protective cover 830 is fixedly connected in the feed pipe 310.

The dredging rod 820 is parallel to the length direction of the feed pipe 310, and the dredging rod 820 is used to be inserted into the storage port of the storage hopper 700. When the blocking plate 711 is opened and the ores are piled up and blocked at the discharge port of the storage hopper 700, the first electric push cylinder 811 is started to drive the dredging rod 820 to be inserted into the storage port of the storage hopper 700, and then the second motor 610 is used to drive the chute body 300 to shake back and forth, so that the dredging rod 820 can shake at the discharge port of the storage hopper 700, thereby realizing automatic dredging of the discharge port of the storage hopper 700 and ensuring the continuity of ore transportation.

[0049] Reference Figure 5 and Figure 6The side walls of the first discharge pipe 320 and the second discharge pipe 330 are both installed with a material discharging mechanism 900. In this embodiment, the material discharging mechanism 900 on the first discharge pipe 320 is taken as an example. The material discharging mechanism 900 includes a driving member 910, and the driving member 910 is installed on the first discharge pipe 320. In this embodiment, the driving member 910 is a second electric push cylinder 911, and the second electric push cylinder 911 is fixedly connected to the first discharge pipe 320. The piston rod of the second electric push cylinder 911 is fixedly connected with a material discharging plate 920, and the material discharging plate 920 is slidably connected to the first discharge pipe 320, and the material discharging plate 920 slides along the length direction of the first discharge pipe 320. In the process of introducing ore into the mine car, the ore tends to accumulate below the discharge port of the chute body 300. If the accumulated ore is moved by manpower, it is not only cumbersome but also laborious. By utilizing the setting of the material-moving mechanism 900, before the chute body 300 rotates, the second electric push cylinder 911 is started, and the second electric push cylinder 911 is used to drive the material-moving plate 920 to slide a certain distance along the length direction of the first discharge pipe 320, and then the chute body 300 is driven to rotate. The accumulated ore can be moved while the ore discharge port is changed, thereby reducing the possibility of the ore being piled up too high and affecting the ore loading.

[0050] The implementation principle of an ore conveying device with bidirectional feeding of a feeding chute in an embodiment of the present application is as follows: by slidingly connecting the second conveyor 210 to the frame 100, during the process of mining and feeding the ore, when the ore feeding position changes, the second conveyor 210 is driven to slide by the adjusting mechanism 400, so that the second conveyor 210 can move forward with the advancement of the ore feeding position, thereby ensuring the convenience of ore feeding. The second conveyor 210 will convey the ore to the first conveyor 110, and then the first conveyor 110 will convey the ore to the storage hopper 700, and then in the chute body 300 that enters, the ore is screened into fine ore and coarse ore by using the screening plate 340 arranged in the chute body 300, and discharged from the first discharge pipe 320 and the second discharge pipe 330 respectively, thereby realizing bidirectional feeding of the fine material chute.
