Description

Technical Field

[0001] The utility model relates to the technical field of telescopic slots, in particular to a telescopic slot device for loading vehicles. Background Art

[0002] In the production industry such as petroleum coke, it is often necessary to ship and load. When loading particles, aggregates or materials mixed with powder, most of the materials are transported to the top of the truck bed through a conveyor belt, and then enter the truck bed or the interior of the car through free fall. In this process, it is necessary to cooperate with a bulk loader or a guide pipe to feed the materials to prevent the materials from being scattered due to external factors such as collisions during the falling process, and to prevent the powder from spreading. However, the commonly used guide pipes in the prior art mostly adopt a fixed structure with a fixed length and height. The vehicle can be loaded when it reaches the specified position. Although it can reduce the steps of debugging the height, it is not suitable for trucks of different heights. Tall trucks are prone to collision with pipes when the trucks are in place. The distance between the end face of the car body of a truck with a low height and the pipe is large, and the discharge port of the pipe is high relative to the height of the car body and does not match.

[0003] At the same time, conventional guide pipes can only guide the direction of falling materials. Some materials will generate dust during the falling process, and this dust will scatter during the falling process and affect the environment.

[0004] Therefore, designing a device that can adjust the height of the telescopic slot, has wide applicability, recycles dust and reduces the impact on the surrounding environment is exactly the problem that the inventor wants to solve. Utility Model Content

[0020] See also Figure 1 The utility model structural view, a telescopic slot device for loading a vehicle, comprises an upper plate 1, three equally spaced mounting cylinders 2 are arranged on the end surface of the upper plate 1, two main dust collecting slots 9 and a blanking main slot 20 are fixedly arranged on the inner sides of the three mounting cylinders 2, the upper ends of the main dust collecting slots 9 and the blanking main slots 20 are open, and the fixing method is bolt fixing, the blanking main slot 20 is arranged between the two main dust collecting slots 9, a dust collecting upper cover 3 is arranged on the upper end of the main dust collecting slots 9, the dust collecting upper cover 3 is connected to the main dust collecting slots 9 by bolts, and a sealing gasket is arranged at the connection to reduce air leakage during vacuuming, the two dust collecting upper covers 3 are connected by a dust collecting pipe 4, and the end of the dust collecting pipe 4 is connected to a vacuum dust collector, and the dust is extracted from the main dust collecting slots 9 by the vacuum dust collector.

[0021] A protective cover 16 is provided at the lower end of the upper plate 1, and two rope threading holes 8 are provided on the end face of the upper plate 1. A right-angle bracket guide wheel 5 is fixedly provided on the side of the rope threading hole 8, and a winch 6 is provided on the side of the right-angle bracket guide wheel 5. The wire rope 7 on the winch 6 passes around the right-angle bracket guide wheel 5 and passes through the rope threading hole 8. The lower end of the wire rope 7 is connected with a lifting ring 19, and the lifting ring 19 is threadedly connected to the upper end of the protective cover 16. The bracket of the right-angle bracket guide wheel 5 is a 90° L-shaped bending structure, and the guide wheel is rotatably provided at the end to carry and guide the wire rope 7. The wire rope 7 of the winch 6 passes around the right-angle bracket guide wheel 5 and is connected to the protective cover 16 through the lifting ring 19. The real-time height and telescopic length of the protective cover 16 are controlled by the simultaneous action of the two winches 6.

[0022] The lower end of the protective cover 16 is open and a dust-proof curtain 18 is connected to the outer wall. The dust-proof curtain 18 includes a rubber curtain body. The spacing between adjacent rubber curtain bodies is less than 1 cm. The dust-proof curtain 18 is used to block materials and dust when the materials are dropped, slow down the diffusion of the materials so that they fall near the designated area, and effectively block the diffusion of dust. Because the falling of the materials will be accompanied by an explosive diffusion of dust, the dust diffusion can be better organized by cooperating with the dust-proof curtain 18 and vacuum extraction.

[0023] The outer sides of the dust collecting main trough 9 and the material dropping main trough 20 are both slidably provided with a first chute 10, the outer side of the first chute 10 is slidably provided with a second chute 11, the outer side of the second chute 11 is slidably provided with a third chute 12, the outer side of the third chute 12 is slidably provided with a fourth chute 13, the outer side of the fourth chute 13 is slidably provided with a fifth chute 14, the outer side of the fifth chute 14 is slidably provided with a sixth chute 15, the three sixth chute 15 are connected and fixed to the shield 16 and pass through the side wall of the upper end of the shield 16, the first chute 10, the second chute 11, the third chute 12, the fourth chute 13, the fifth chute 14, the sixth chute 15 The upper end is respectively provided with six annular flanges with different diameters but the same width and thickness, and the lower ends of the six annular flanges are respectively connected with six cylinders with different diameters but the same thickness and height. The inner diameter of the annular flange located at the bottom is smaller than the outer diameter of the annular flange located at the top, and the inner diameter of the annular flanges connected together is smaller than the inner diameter of the cylinder. The diameters of the six slides increase successively from the inside to the outside, and the upper ends are limited by overlapping each other. When the slide rises upward, the top of the annular flange arranged on the slide below presses against the bottom of the annular flange arranged on the slide above, forming an action relationship in which the upper and lower parts are overlapped in sequence and pressed upward to pull up.

[0024] Four evenly distributed limit bolts 17 are connected to the lower end circumferential surfaces of the dust collecting main trough 9, the material dropping main trough 20, the first chute 10, the second chute 11, the third chute 12, the fourth chute 13, the fifth chute 14 and the sixth chute 15. The nut end of the limit bolt 17 cooperates with the annular flange in the vertical direction. The function of the limit bolt 17 is to set a limit on the circumferential surface of the cylinder of the chute. The movement trajectory of the annular flange is blocked by the limit bolt 17, so that when adjacent chutes slide relatively, the limit flange arranged on the chute below can overlap on the limit bolt 17, so that multiple chutes can be overlapped in sequence through the annular flange and the limit bolt 17.

[0025] In order to prevent the limiting bolts 17 from colliding with each other during the lifting and retracting of multiple slide grooves, the distance between adjacent cylinders is greater than the thickness of the nut of the limiting bolt 17, and the distance between adjacent cylinders is greater than the difference between the length of the limiting bolt 17 and the wall thickness of the cylinder.

[0026] Furthermore, the limiting bolts 17 connected to different slide grooves are staggered so that the limiting bolts 17 arranged on different slide grooves have different angles and their projections on the horizontal plane do not overlap, which can better avoid collision of the limiting bolts 17.

[0027] By operating the winch 6 to retract and release the wire rope 7, the lifting and lowering of the shield 16 can be controlled, thereby controlling the lifting and lowering of the sixth chute 15 connected to the shield 16. When the shield 16 descends, relying on gravity, the six chutes gradually extend and expand, and the length of the extension channel is extended until the annular flange and the limit bolts 17 on the chute are overlapped in sequence and completely stop falling. At this time, the maximum length of the extension is reached. When shrinking, the winch 6 rotates in the opposite direction, winds and pulls the wire rope 7 to control the shield 16 to rise, and the chute at the bottom moves upward. The annular flange at the bottom supports the annular flange of the upper chute, and successively lifts up the chute at the top until all the chutes rise to the top, and the top of the first chute 10 stops near the upper plate 1, completing the contraction. When the chute is extended and discharged, the material falling through the middle blanking main chute 20 and the chute directly enters the truck, and the dust generated is vacuumed upward and processed from the dust collecting main chute 9 and the chute on both sides.

[0028] The utility model adopts a telescopic sleeve structure that can be gradually extended and retracted and the height can be adjusted. One section is overlapped with another section to form an elongated blanking channel, and can also be pulled up and contracted together to reduce the occupied space. The bottom height of the channel can be adjusted by controlling the pulling height, thereby realizing the function of being able to adjust the height of the telescopic groove and having a wide range of applicability. A dust collecting main groove 9 for negative pressure collection and extraction of dust is arranged on both sides of the blanking main groove 20. The dust scattered with the blanking is collected and extracted by negative pressure for dust removal, thereby realizing the function of recycling dust and reducing the impact on the surrounding environment.
