Description
Technical Field
[0001] This utility model relates to the field of impeller coal feeder technology, specifically an impeller coal feeder with a baffle structure. Background Technology
[0002] Impeller feeders are an indispensable main piece of equipment in slotted coal trenches of thermal power plants. They are widely used in industries such as coal, mining, metallurgy, building materials, and chemicals. They can travel along the longitudinal axis of the coal trench or stop in one place to quantitatively, evenly and continuously feed coal onto the coal conveyor belt.
[0003] During coal transportation, coal may fall through the gaps on both sides of the conveyor belt, which is not only troublesome to clean, but may also damage the equipment below the belt. Therefore, a material blocking structure is installed on both sides of the conveyor belt. However, the existing material blocking structure only passively blocks the material and is not convenient to adjust. Coal particles may splash out due to compression and collision during the transportation process, affecting the actual use effect of the material blocking component. Utility Model Content
[0004] The purpose of this utility model is to provide an impeller coal feeder with a material blocking structure, which solves the problem mentioned in the background art that coal may fall from the gaps on both sides of the belt during the coal transportation process. This is not only troublesome to clean, but may also damage the equipment below the belt. However, the existing material blocking structure only passively blocks the material and is not convenient to adjust. Coal particles may splash out due to compression and collision during the transportation process.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an impeller coal feeder with a baffle structure, comprising a feed trough, an adjusting trough, and a baffle plate. Two discharge ports are opened on both sides of the top of the feed trough, and a discharge trough is fixedly connected to the bottom surface of the feed trough below the discharge ports. Two adjusting troughs are fixedly connected to the center of the bottom of the feed trough. A threaded rod is rotatably connected to the inner side of the adjusting trough. A threaded block passes through the surface of the threaded rod and is threadedly connected to the threaded block. A connecting rod is fixedly connected to the bottom of the threaded block, and a baffle plate is fixedly connected to the bottom of the connecting rod. Fixing strips are fixedly connected to both sides of the bottom of the discharge trough. The fixing strips are parallel to the baffle plate, and a splash guard is fixedly connected between the fixing strips and the baffle plate.
[0006] In this technical solution, the threaded block moves along the threaded rod, thereby driving the baffle plate to move laterally. During the lateral movement, the baffle plates on both sides move the coal towards the center of the conveyor belt assembly, thus concentrating the coal and minimizing leakage from the gaps on both sides of the conveyor belt, thereby improving transportation efficiency. As the coal enters the conveyor belt assembly, it may fly out from above the baffle plate due to collision and compression. Therefore, a splash guard is installed to move with the baffle plate to block the coal, minimizing coal leakage and improving transportation efficiency.
[0007] Preferably, a second servo motor is fixedly connected to one end of the adjustment groove, and the outer end of the drive shaft of the second servo motor is fixedly connected to one end of the threaded rod.
[0008] Preferably, a soft pad is fixedly connected to the bottom of the baffle plate, and the soft pad is in contact with the surface of the conveyor belt assembly below.
[0009] Preferably, a shovel is fixedly connected to the bottom of the surface of the baffle plate facing the center of the conveyor belt assembly.
[0010] Preferably, the two adjustment slots at the bottom of the feed trough are both perpendicular to the baffle plate, and the outer ends of the two adjustment slots at the bottom of the feed trough are respectively connected to their respective No. 2 servo motors.
[0011] Preferably, the splash guard is provided with sufficient length for the normal movement and stretching of the baffle plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model can block coal by using an adjusting groove, a threaded rod, a threaded block, and a baffle plate. The two adjusting grooves control the corresponding baffle plates respectively. The threaded block moves along the threaded rod, thereby driving the baffle plates to move laterally. During the lateral movement, the baffle plates on both sides will move the coal towards the center of the conveyor belt assembly, thereby making the coal more concentrated and minimizing leakage from the gaps on both sides of the conveyor belt, thus improving the efficiency of transportation.
[0014] 2. This utility model uses a fixing strip, a baffle plate, and a splash guard to prevent coal from splashing. During the process of coal entering the conveyor belt assembly, it may fly out from above the baffle plate due to collision and compression. Therefore, the splash guard is set to move with the baffle plate to block the coal, thereby minimizing the amount of coal flying out and improving the efficiency of transportation.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.
[0021] A type of impeller feeder with a baffle structure, see [link / reference]. Figures 1 to 3 The feeding trough includes a feeding trough 1, an adjusting trough 6, and a baffle plate 10. Two discharge ports 3 are opened on both sides of the top of the feeding trough 1, and a discharge trough 5 is fixedly connected to the bottom surface of the feeding trough 1 below the discharge ports 3. Two adjusting troughs 6 are fixedly connected to the center of the bottom of the feeding trough 1. A threaded rod 7 is rotatably connected to the inner side of the adjusting trough 6. A threaded block 8 passes through the surface of the threaded rod 7 and is threadedly connected to the threaded block 8. A connecting rod 9 is fixedly connected to the bottom of the threaded block 8, and a baffle plate 10 is fixedly connected to the bottom of the connecting rod 9. The threaded block 8 moves along the threaded rod 7, from... The baffle plate 10 moves laterally, and during this movement, the baffle plates 10 on both sides move the coal toward the center of the conveyor belt assembly 4, thus concentrating the coal and minimizing leakage from the gaps on both sides of the conveyor belt. The bottom of the feed chute 5 is fixedly connected to both sides of the bottom with fixing strips 11, which are parallel to the baffle plate 10. A splash guard 12 is fixedly connected between the fixing strip 11 and the baffle plate 10. The splash guard 12 moves with the baffle plate 10, thereby blocking the coal and minimizing coal leakage.
[0022] Specifically, such as Figure 3 As shown, a second servo motor 701 is fixedly connected to one end of the adjusting groove 6. The outer end of the drive shaft of the second servo motor 701 is fixedly connected to one end of the threaded rod 7. After the second servo motor 701 is started, it drives the threaded rod 7 to rotate, thereby causing the threaded block 8 to move laterally with the baffle plate 10 below, thereby pushing the coal to concentrate in the center of the conveyor belt assembly 4.
[0023] It is worth noting that, such as Figure 2As shown, a soft pad 14 is fixedly connected to the bottom of the baffle plate 10, and the soft pad 14 is in contact with the surface of the conveyor belt assembly 4 below. The soft pad 14 can fully contact the surface of the conveyor belt assembly 4, thereby filling the gap between the baffle plate 10 and the conveyor belt assembly 4.
[0024] It is worth noting that, such as Figure 2 As shown, a shovel 13 is fixedly connected to the bottom of the surface of the baffle plate 10 facing the center of the conveyor belt assembly 4. The shovel 13 can more easily shovel coal during movement.
[0025] It is worth noting that, such as Figure 3 As shown, the two adjustment slots 6 at the bottom of the feed trough 1 are both perpendicular to the baffle plate 10, and the outer ends of the two adjustment slots 6 at the bottom of the feed trough 1 are respectively connected to their respective second servo motors 701. Therefore, the baffle plates 10 on both sides can be moved independently to push the coal.
[0026] It is worth noting that, such as Figure 2 and Figure 3 As shown, the splash guard 12 is reserved with sufficient length for the normal movement and stretching of the baffle plate 10, so as to avoid the baffle plate 10 pulling on the splash guard 12 during movement and causing it to break or be damaged.
[0027] In actual use, the feed chute 1 is set on top of the conveyor belt assembly 4 via the moving wheel 101 and can move along the conveyor belt assembly 4. After moving to the coal position, the impeller body 2 rotates under the drive of the first servo motor 201. During the rotation process, the coal is fed into the feed chute 1 in batches and enters the transmission belt assembly from the discharge port 3 and discharge chute 5 for transportation. During this process, the two adjusting grooves 6 control the corresponding baffle plates 10 respectively. The threaded block 8 moves along the threaded rod 7, thereby driving the baffle plates 10 to move laterally. During the lateral movement, the baffle plates 10 on both sides will move the coal towards the center of the conveyor belt assembly 4, thereby making the coal more concentrated and minimizing leakage from the gaps on both sides of the conveyor belt, thus improving the transportation efficiency. During the process of coal entering the conveyor belt assembly 4, it may fly out from above the baffle plates 10 due to collision and compression. Therefore, a splash guard 12 is set to move with the baffle plates 10 to block the coal, thereby minimizing the amount of coal flying out and improving the transportation efficiency.
