Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation technology, specifically to a split-type coal unloading nozzle structure. Background Technology

[0002] In coal transportation and loading / unloading systems, the unloading nozzle is a key component used to control the discharge of coal from conveying equipment (such as belt conveyors and chutes) to target containers (such as train carriages, ships, or coal storage silos).

[0003] Traditional coal unloading nozzles are typically square or cylindrical metal pipes, open at both ends, serving as coal flow channels. Some unloading nozzles have movable baffles at the bottom, which are opened manually or electrically as a whole. This makes it difficult to achieve precise control of coal flow, easily causing coal to spill or accumulate. Furthermore, coal inevitably sticks to the baffles, making it difficult to open and close them after long-term use. Therefore, a new type of split-type coal unloading nozzle structure is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that it is difficult to achieve precise control of coal flow when the single-sided baffle is opened as a whole, and it is also prone to clogging. This invention provides a novel split-type coal unloading nozzle structure.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a split coal unloading nozzle structure, including a main frame, a baffle and an adjustment mechanism;

[0006] After the main frame is opened at the top and bottom, a pair of baffles are slidably installed on the bottom surface;

[0007] The two baffles move closer or further apart under the action of the adjustment mechanism, adjusting the size of the opening at the bottom of the main frame. When the two baffles are pressed tightly together, the bottom of the main frame is closed.

[0008] When the two baffles slide under the action of the adjustment mechanism, a cleaning component is installed inside the main frame that is in close contact with the two baffles.

[0009] As an improvement, the main frame includes a square frame and an arc-shaped plate;

[0010] After the square frame is opened at the top and bottom, a pair of arc-shaped plates are set on the bottom surface in a mirror image. After the center of the two baffles coincides with the center of the arc-shaped plates, they slide against the two arc-shaped plates respectively.

[0011] As an improvement, the adjustment mechanism includes a limit guide groove, a slide bar, and a drive mechanism;

[0012] The limiting guide groove is fixedly opened on the outer wall of the main frame and coincides with the center of the arc plate and the baffle. A pair of sliding rods are provided. After one end of the two sliding rods is vertically fixedly connected to the center of the two baffles respectively, the other end is slidably connected to the limiting guide groove. Under the drive of the driving mechanism, the two sliding rods move closer or further away from each other along the limiting guide groove.

[0013] The adjustment mechanism is mirrored in a pair, each connected to one end of the baffle.

[0014] As an improvement, the drive mechanism includes a drive groove, a hydraulic telescopic rod, and a connecting rod;

[0015] The drive groove is located on the outer wall of the main frame and is positioned on the axis of symmetry of the two baffles. After the hydraulic telescopic rod is fixedly installed in the drive groove, the output end is connected to a slider that is slidably connected to the drive groove. A pair of connecting rods are symmetrically hinged on the slider, and the other ends of the two connecting rods are respectively hinged to the ends of the two sliding rods.

[0016] As an improvement, the cleaning component includes a scraper, which is fixedly set between two arc-shaped plates on the bottom surface of the square frame, and a pair is mirrored thereon, with the two scrapers closely adhering to the inner walls of the two baffles for cleaning.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. By using a double-baffle symmetrical sliding mechanism with a limiting guide groove and a hydraulic drive mechanism, precise control of the coal unloading port size is achieved, which facilitates adjustment of coal flow rate according to different working conditions;

[0019] 2. The baffles fit together tightly and are designed with an arc shape to ensure no leakage when closed, thus improving safety and environmental friendliness;

[0020] 3. A mirror scraper is installed to scrape away residual coal slag on the inner wall in sync with the movement of the baffle, preventing coal accumulation and blockage and extending service life. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0028] A split-type coal unloading nozzle structure, combined with an attached Figure 1 and 3 As shown in Figure 4, the main frame includes a main frame, baffle 1 and adjustment mechanism; after the main frame is opened up and down, a pair of baffles 1 are slidably arranged on the bottom surface; the main frame includes a square frame 2 and an arc plate 3; after the square frame 2 is opened up and down, a pair of arc plates 3 are slidably arranged on the bottom surface; after the centers of the two baffles 1 and the arc plates 3 coincide, they slide against the two arc plates 3 respectively.

[0029] The two baffles 1 move closer or further apart under the action of the adjustment mechanism, adjusting the size of the opening at the bottom of the main frame. When the two baffles 1 are pressed tightly together, the bottom of the main frame is closed. The adjustment mechanism includes a limiting guide groove 4, a sliding rod 5, and a driving mechanism. The limiting guide groove 4 is fixedly opened on the outer wall of the main frame and coincides with the center of the arc plate 3 and the baffle 1. A pair of sliding rods 5 are provided. One end of each sliding rod 5 is vertically fixedly connected to the center of the two baffles 1, and the other end is slidably connected to the limiting guide groove 4. The two sliding rods 5 move closer or further apart along the limiting guide groove 4 under the action of the driving mechanism. A pair of adjustment mechanisms are mirror images of each other and are connected to both ends of the baffle 1.

[0030] The drive mechanism includes a drive groove 6, a hydraulic telescopic rod 7 and a connecting rod 8. The drive groove 6 is opened on the outer wall of the main frame and is located on the axis of symmetry of the two baffles 1. After the hydraulic telescopic rod 7 is fixedly installed in the drive groove 6, the output end is connected to a slider 9 that is slidably connected to the drive groove 6. A pair of connecting rods 8 are symmetrically hinged on the slider 9, and the other ends of the two connecting rods 8 are respectively hinged to the ends of the two sliding rods 5.

[0031] The hydraulic telescopic rod 7 pushes the slider 9 forward along the drive groove 6. The slider 9 drives the connecting rods 8 on both sides to open, which in turn pushes the slide rod 5 to move outward. The slide rod 5 drives the baffle 1 to slide to both sides along the limit guide groove 4, opening the coal unloading port. The stroke of the hydraulic telescopic rod 7 can be adjusted as needed to control the opening of the baffle 1 and realize the control of coal flow. Example 2

[0032] Based on Example 1, combined with Appendix Figure 2 As shown, when the two baffles 1 slide under the action of the adjusting mechanism, a cleaning assembly is installed inside the main frame that is in close contact with the two baffles 1. The cleaning assembly includes a scraper 10, which is fixedly installed between two arc-shaped plates 3 on the bottom surface of the square frame 2, and a pair of scrapers 10 are mirror images of each other. The two scrapers 10 clean the inner walls of the two baffles 1 in close contact. As the baffles 1 open and close, the scraper 10 always slides in close contact with the inner wall of the baffles 1, and the scraper 10 scrapes away the coal slag, fine powder and other impurities adhering to the surface of the baffles 1, keeping the baffles 1 clean and preventing blockage.

[0033] In specific implementation, the coal unloading nozzle is installed at the end outlet of the belt conveyor or chute, ensuring that it is aligned with the receiving equipment below (such as a car or ship's hold), the hydraulic telescopic rod 7 is in the retracted state, the two baffles 1 are closed, and the coal unloading port is completely sealed to prevent coal leakage when not in operation.

[0034] When the hydraulic system is started, the hydraulic telescopic rod 7 pushes the slider 9 forward along the drive groove 6. The slider 9 drives the connecting rods 8 on both sides to open, which in turn pushes the slide rod 5 to move outward. The slide rod 5 drives the baffle 1 to slide to both sides along the limit guide groove 4 to open the coal unloading port. The stroke of the hydraulic telescopic rod 7 can be adjusted as needed to control the opening of the baffle 1 and achieve precise control of the coal flow.

[0035] As the baffle 1 opens and closes, the scraper 10 set on the bottom surface of the square frame 2 always slides close to the inner wall of the baffle 1. The scraper 10 scrapes away the coal slag, fine powder and other impurities adhering to the surface of the baffle 1, keeping the baffle 1 clean and preventing blockage.

[0036] After coal unloading is completed, the hydraulic system reverses its action, the slider 9 retracts, the connecting rod 8 drives the sliding rod 5 to move inward, the baffle 1 moves towards the center until it is completely closed, the coal unloading port is sealed to prevent dust from overflowing or coal from accumulating.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
