Reciprocating moving mechanism applied to coal feeders Technical Field
[0001] This utility model relates to the field of coal transportation equipment technology, and in particular to a reciprocating moving mechanism applied to a coal feeder. Background Technology
[0002] A coal feeder is a device used to extract coal from a coal pile or storage device and supply it to equipment such as a coal-fired boiler. It typically consists of a feeding device, a conveying device, and a discharging device. The feeding device is responsible for conveying coal from the stockpiling area or storage device to the coal feeder.
[0003] For example, a patent entitled "A Coal Feeder Transportation Device" (patent application number: CN202322003162.8) discloses a coal feeder transportation device. By modularizing the coal feeder transportation device into multiple liftable transportation units, the manufacturing, installation efficiency and maintenance convenience of the coal feeder transportation device can be improved through structural modularization. However, the lifting height is limited, and multiple transportation units are required to achieve a higher conveying effect. At the same time, when coal is piled together for transportation, the problem of falling is difficult to solve.
[0004] Therefore, it is necessary to propose a reciprocating moving mechanism for use on coal feeders to solve the above problems. Summary of the Invention
[0005] The purpose of this utility model is to provide a reciprocating moving mechanism for use on a coal feeder, in order to solve the problems in the prior art where the lifting height of the device is limited, multiple transport units are required to achieve a higher conveying height, and the problem of coal falling off when transported together is difficult to solve.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating moving mechanism applied to a coal feeder, including a vertical frame, wherein two vertical frames are provided, and a drive shaft is rotatably connected between the top ends of the two vertical frames. Gears are fixed on the outer sides of both ends of the drive shaft, and a conveying chain is meshed on the outer sides of both gears. The conveying chain is distributed along the height direction of the vertical frame.
[0007] Two conveyor chains are connected to a load-bearing frame at one end, and a connecting rod is fixed to one side of the other end of each of the two conveyor chains. A movable box is fixed to each of the two connecting rods. Connecting frames are fixed to both sides of the movable box. A through groove is opened at the top of each of the two connecting frames, and an extension plate is slidably arranged in the through groove. The bottom ends of the two extension plates extend out of the through groove, and a horizontal plate is fixed between the two extension ends. An electric push rod is fixed between the top of the horizontal plate and the movable box. Multiple needles are fixed at the top of the horizontal plate. A through hole for the needles to pass through is opened at the bottom of the movable box. A pressure sensor is embedded in the bottom of the movable box.
[0008] Preferably, a connecting rope is fixed to the bottom end of the load-bearing frame, and a winding box is installed below the connecting rope. The top of the winding box has a winding hole for the connecting rope to pass through.
[0009] Preferably, a winding motor is fixed inside the winding box, the drive shaft of the winding motor is fixedly connected to the winding shaft, the winding shaft is rotatably disposed inside the winding box, and the connecting rope is wound around the outside of the winding shaft.
[0010] Preferably, a connecting plate is fixed between the two uprights, and the two ends of the conveyor chain are respectively located on both sides of the uprights.
[0011] Preferably, the two gears are the same size and the two gears are the same height.
[0012] Preferably, a buffer pad is fixed at the bottom end of the cross plate.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. In the actual operation of this utility model, when coal is placed inside the moving box, the pressure sensor detects the pressure signal and controls the electric push rod to retract through the controller, so that the horizontal plate is close to the bottom of the moving box. At this time, the extension plates on both sides of the horizontal plate extend upward to connect the frame and block the sides of the moving box to prevent the coal from falling from the sides during transportation. At the same time, the needles will penetrate into the coal pile through the through hole to enhance the connection between the coal and the coal, enhance the stability of the coal when it rises, and prevent the gaps between the coal from being too large, which would cause the coal to slip during the rise.
[0015] 2. When coal needs to be discharged, extend the electric push rod downwards, causing the horizontal plate to move away from the bottom of the moving box, thereby causing the extension plate and the spikes to retract, releasing the connection with the coal, thus facilitating the discharge of coal.

It includes a vertical frame 1, two vertical frames 1 are provided, and a drive shaft is rotatably connected between the top ends of the two vertical frames 1. Gears 2 are fixed on the outer sides of both ends of the drive shaft, and conveying chains 3 are meshed on the outer sides of the two gears 2. The conveying chains 3 are distributed along the height direction of the vertical frame 1.
[0023] One end of each of the two conveyor chains 3 is connected to a load-bearing frame 4. A connecting rod 9 is fixed to one side of the other end of each of the two conveyor chains 3. A movable box 5 is fixed to each of the two connecting rods 9. A connecting rope 7 is fixed to the bottom of the load-bearing frame 4. A winding box 8 is installed below the connecting rope 7. A winding hole is opened at the top of the winding box 8 for the connecting rope 7 to pass through. A winding motor is fixed inside the winding box 8. The drive shaft of the winding motor is fixedly connected to the winding shaft. The winding shaft is rotatably located inside the winding box 8. The connecting rope 7 is wound around the outside of the winding shaft.
[0024] In the actual operation of this utility model, when the winding motor starts and winds the connecting rope 7, it will pull the conveyor chain 3 to move towards the winding motor, thereby driving the movable box 5 connected to the other end of the conveyor chain 3 to move upward. When coal is placed on the movable box 5, it can drive the collected coal and the movable box 5 to rise together, completing the mobile conveying.
[0025] Similarly, when the winding motor rotates in the opposite direction and releases the winding connecting rope 7, the conveyor chain 3 will drive the moving box 5 to descend, which can repeatedly transport coal at a high altitude.

An extension plate 12 is slidably arranged in the through groove.

An electric push rod 14 is fixed between the top of the horizontal plate 13 and the mobile box 5. Multiple needles 15 are fixed at the top of the horizontal plate 13. The bottom of the mobile box 5 is provided with a through hole 10 for the needles 15 to pass through. A pressure sensor is embedded in the bottom of the mobile box 5.
[0027] In the actual operation of this utility model, when coal is placed inside the movable box 5, the pressure sensor detects the pressure signal and controls the electric push rod 14 to retract through the controller, so that the horizontal plate 13 is close to the bottom of the movable box 5. At this time, the extension plates 12 on both sides of the horizontal plate 13 extend upward to connect the frame 11 and block the sides of the movable box 5 to prevent coal from falling from the sides during transportation. At the same time, the needles 15 will penetrate into the coal pile through the through hole 10 to enhance the connection between the coal and the coal, enhance the stability of the coal when it rises, and prevent the gaps between the coal from being too large, which would cause the coal to slip during the rise.
[0028] When coal needs to be discharged, the electric push rod 14 extends downward, causing the horizontal plate 13 to move away from the bottom of the moving box 5, thereby causing the extension plate 12 and the needle 15 to retract, releasing the connection with the coal, thus facilitating the discharge of coal.
[0029] A connecting plate 6 is fixed between the two uprights 1. The two ends of the conveyor chain 3 are respectively set on both sides of the uprights 1. The two gears 2 are the same size and the two gears 2 are the same height. A buffer pad is fixed at the bottom of the horizontal plate 13.
