Description

Technical Field

[0001] This utility model relates to the field of weighing bin technology, and in particular to a weighing bin for use in rapid loading stations. Background Technology

[0002] A rapid loading station is an automated equipment used for efficient and quantitative loading of bulk materials (such as coal, ore, cement, etc.), and is widely used in mines, ports, railways and other scenarios.

[0003] During operation at the rapid loading station, materials enter the weighing hopper through a buffer hopper at the top of the station. High-precision weighing sensors are installed on the outside of the weighing hopper, which can monitor the weight of the materials in the weighing hopper in real time. A hydraulic valve is installed at the bottom of the weighing hopper. The valve is opened by a hydraulic system to allow the materials to be discharged. When the valve plate moves back and forth, materials can easily enter the groove of the valve plate. Over time, the material will be compacted by the movement of the valve plate. In the long run, the valve plate will not be able to completely seal when it moves, resulting in coal leakage and affecting the normal use of the weighing hopper. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when the valve plate moves back and forth, material easily enters the groove of the valve plate. The long-term accumulation of material will be compacted by the movement of the valve plate. Over time, this will cause the valve plate to be unable to completely seal when it moves, resulting in coal leakage and affecting the normal use of the weighing bin. Therefore, a weighing bin for a rapid loading station is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a weighing bin for a rapid loading station, comprising a support frame, a hopper fixedly connected to the outer surface of the support frame, a plurality of weighing sensors disposed on the outer surface of the hopper, a frame disposed at the bottom end of the hopper, the frame being fixed to the outer surface of the support frame, a hydraulic rod disposed at one end of the frame, a valve plate fixedly connected to the output rod of the hydraulic rod, the valve plate sliding on the inner wall of the frame, and a cleaning device disposed on the outer surface of the valve plate for cleaning the valve plate moving track inside the frame.

[0006] Furthermore, the cleaning device includes two threaded cylinders and two screws. The two screws are fixedly connected to both sides of the inner wall of the frame, and the two threaded cylinders are rotatably connected to both sides of the inner wall of the valve plate. The inner wall of the threaded cylinder is threadedly connected to the outer surface of the screw. A number of scraping blocks are fixedly connected to one end of the threaded cylinder, and the scraping blocks are circumferentially distributed on the outer surface of the threaded cylinder.

[0007] Furthermore, the outer surface of the scraper is provided with several auxiliary grooves, and the inner walls of the auxiliary grooves are inclined at both sides.

[0008] Furthermore, a brush plate is fixedly connected to one side of the scraper, and one end of the brush plate is provided with stiff bristles.

[0009] Furthermore, a pad made of rubber is fixedly connected to one end of the threaded cylinder.

[0010] Furthermore, one end of the frame is provided with several through slots, which are linearly distributed on the outer surface of the frame.

[0011] Furthermore, a striking device is provided on one side of the bottom end of the frame. The striking device includes a rotating shaft, a striking rod is fixedly connected to the outer surface of the rotating shaft, a coil spring is provided at one end of the rotating shaft, and the two ends of the coil spring are fixedly connected to one side of the rotating shaft and one side of the inner wall of the frame, respectively. Two stops are fixedly connected to the top end of the striking rod.

[0012] Furthermore, a rubber rod is fixedly connected to the end of the striking rod away from the pivot, and the outer surface of the rubber rod is cylindrical.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting a striking device, when the hydraulic rod operates to move the valve plate, the threaded cylinders on both sides of the inner wall of the valve plate will rotate, causing the scraper to rotate and scrape and clean the material on the moving path of the valve plate on the inner wall of the frame. This prevents the material from accumulating on the inner wall of the frame and blocking the moving path of the valve plate, thus affecting the sealing effect of the valve plate on the bottom of the silo and improving the stability of the weighing silo during use.

[0020] Example 1, as Figure 1-2 As shown, the weighing bin for a rapid loading station includes a support frame 1. A hopper 4 is fixedly connected to the outer surface of the support frame 1. Several weighing sensors 5 are installed on the outer surface of the hopper 4. A frame 6 is installed at the bottom of the hopper 4 and is fixed to the outer surface of the support frame 1. A hydraulic rod 7 is installed at one end of the frame 6. A valve plate 8 is fixedly connected to the output rod of the hydraulic rod 7. The valve plate 8 slides on the inner wall of the frame 6. A cleaning device 2 is installed on the outer surface of the valve plate 8 to clean the moving track of the valve plate 8 inside the frame 6. When the weighing bin is working, it receives signals from the support frame 1. The material in the buffer bin (not shown in the figure) is controlled by a gate to flow into the silo 4. After the material enters the silo 4, the weighing sensor 5 receives the weight change of the silo 4 and generates an electrical signal. The signal from the weighing sensor 5 is collected through the junction box and transmitted to the weighing instrument. The weighing instrument converts the signal into the weight of the material and displays it in real time on the screen in the control room. Then, the hydraulic rod 7 is controlled to operate and retract, which drives the valve plate 8 to move on the inner wall of the frame 6, which can open or close the bottom of the silo 4, so that the material is output through the bottom of the silo 4 or the silo 4 is closed.

[0021] Reference Figure 1-4 As shown in this embodiment: the cleaning device 2 includes two threaded cylinders 22 and two screws 21. The two screws 21 are fixedly connected to both sides of the inner wall of the frame 6. The two threaded cylinders 22 are rotatably connected to both sides of the inner wall of the valve plate 8. The inner wall of the threaded cylinder 22 is threadedly connected to the outer surface of the screw 21. A number of scraper blocks 23 are fixedly connected to one end of the threaded cylinder 22. The scraper blocks 23 are circumferentially distributed on the outer surface of the threaded cylinder 22. By setting the scraper blocks 23, when the hydraulic rod 7 moves the valve plate 8, the threaded cylinders 22 on both sides of the inner wall of the valve plate 8 will move and rotate on the outer surface of the two screws 21, which will drive the scraper blocks 23 at one end of the threaded cylinder 22 to rotate. The scraper blocks 23 scrape and clean the material on the moving path of the valve plate 8 on the inner wall of the frame 6, so as to avoid the material from accumulating on the inner wall of the frame 6 and blocking the moving path of the valve plate 8, affecting the sealing effect of the valve plate 8 on the bottom of the silo 4, and improving the stability of the weighing silo during use.

[0022] Reference Figure 2-4 As shown in this embodiment: the outer surface of the scraper 23 is provided with several auxiliary grooves 24. The inner walls of the auxiliary grooves 24 are inclined at both sides. By setting the auxiliary grooves 24, the contact area between the outer surface of the scraper 23 and the material attached to the inner wall of the frame 6 can be increased, thereby improving the cleaning effect of the scraper 23 on the material. The inclined inner wall of the auxiliary groove 24 makes it easier for the material to leave the interior of the auxiliary groove 24. A brush plate 25 is fixedly connected to one side of the scraper 23. One end of the brush plate 25 is provided with hard bristles. When the scraper 23 rotates, the hard bristles at one end of the brush plate 25 will contact the inner wall surface of the frame 6, further sweeping away the material on the inner wall of the frame 6 and improving the cleaning effect.

[0023] Reference Figure 2-4 As shown in this embodiment: a pad 27 is fixedly connected to one end of the threaded cylinder 22. The pad 27 is made of rubber. By setting the rubber pad 27, the contact point between one end of the threaded cylinder 22 and the inner wall of the frame 6 when the valve plate 8 moves to close the bottom of the hopper 4 can be buffered. Several through grooves 26 are opened at one end of the frame 6. The through grooves 26 are linearly distributed on the outer surface of the frame 6. By opening several through grooves 26 on the outer surface of the frame 6, the material scraped off when the valve plate 8 moves in the direction of the through grooves 26 can be output through the through grooves 26.

[0024] Reference Figure 1-3 As shown in this embodiment: a striking device 3 is provided on one side of the bottom end of the frame 6. The striking device 3 includes a rotating shaft 31, and a striking rod 32 is fixedly connected to the outer surface of the rotating shaft 31. A coil spring 33 is provided at one end of the rotating shaft 31. The two ends of the coil spring 33 are fixedly connected to one side of the rotating shaft 31 and one side of the inner wall of the frame 6, respectively. Two stops 34 are fixedly connected to the top end of the striking rod 32. When the valve plate 8 moves to fully open the bottom end of the hopper 4, one end will contact one side of the stop 34 and push the stop 34 to control the striking rod 32. The upward rotation of the pivot 31 causes the end of the striking rod 32 away from the pivot 31 to contact the outer surface of the valve plate 8 and generate an impact, causing the valve plate 8 to vibrate. This further knocks off the material adhering to both sides of the valve plate 8, improving the cleaning effect on the surface of the valve plate 8 and the frame 6. A rubber rod 35 is fixedly connected to the end of the striking rod 32 away from the pivot 31. The outer surface of the rubber rod 35 is cylindrical. By setting the cylindrical rubber rod 35, the striking rod 32 will not make any abnormal noise when it strikes the valve plate 8.

[0025] Working Principle: When the weighing silo is working, it receives material from the buffer silo. The buffer silo controls the flow of material into the silo 4 through a gate. After the material enters the silo 4, the load cell 5 receives the weight change of the silo 4 and generates an electrical signal. The signal from the load cell 5 is collected through the junction box and transmitted to the weighing instrument. The weighing instrument converts the signal into the material weight and displays it in real time on the screen in the control room. Subsequently, the hydraulic rod 7 is controlled to retract, causing the valve plate 8 to move on the inner wall of the frame 6, which can open or close the bottom of the silo 4, allowing material to be output through the bottom of the silo 4 or closing the silo 4. When the hydraulic rod 7 moves the valve plate 8, the threaded cylinders on both sides of the inner wall of the valve plate 8... 22 will move and rotate on the outer surface of the two screws 21, causing the scraper 23 at one end of the threaded cylinder 22 to rotate. The scraper 23 scrapes and cleans the material on the moving path of the valve plate 8 on the inner wall of the frame 6, preventing the material from accumulating on the inner wall of the frame 6 and blocking the moving path of the valve plate 8. When the valve plate 8 moves and fully opens the bottom of the hopper 4, one end will contact one side of the stop block 34 and push the stop block 34 to control the striking rod 32 to rotate upward through the rotating shaft 31, so that the end of the striking rod 32 away from the rotating shaft 31 contacts the outer surface of the valve plate 8 and generates an impact, causing the valve plate 8 to vibrate, further knocking off the material attached to both sides of the valve plate 8.
