Technical Field
[0001] This utility model relates to the technical field of powder material loading and unloading equipment, specifically a telescopic chute used for loading powder silos. Background Technology
[0002] Telescopic chutes are equipment specifically designed for loading and unloading powdery, granular, and lumpy bulk materials, and are widely used in industries such as grain, cement, docks, and feed. Their core structure employs a double-layered casing (chute and dust cover), featuring dust prevention, reduced material breakage, environmental friendliness, and high efficiency. Supporting manual, automatic, or remote control, loading powder silos is a crucial step in the production, storage, and transportation of powdery materials.
[0003] Most existing chutes have fixed structures and non-adjustable lengths. This makes them difficult to adapt flexibly to different heights and types of transport vehicles. For taller tank trucks or freight cars with higher cargo compartments, fixed-length chutes cannot extend to suitable positions, requiring manual guidance of powder materials during loading, increasing labor intensity and costs, and easily leading to material spillage, waste, and environmental pollution. Therefore, those skilled in the art have provided a telescopic chute for loading powder silos to solve the problems mentioned in the background art. Utility Model Content

[0024] Please see Figures 1-5 In this embodiment of the present invention, a telescopic chute for loading powder silos includes a lifting mechanism 1 and a first chute pipe 2. A second chute pipe 3 is sleeved on the outside of the first chute pipe 2, and a third chute pipe 4 is sleeved on the outside of the second chute pipe 3. Limiting plates 5 are connected to the outer surfaces of the first chute pipe 2 and the second chute pipe 3. Rubber pads 6 are connected to the upper surfaces of the two limiting plates 5. A ring-shaped arrangement of fixing plates 7 is connected to the outer surface of the first chute pipe 2. The overall structure is compact, which can reduce dust during the powder conveying process, improve the quality of the working environment, and improve loading efficiency and safety.
[0025] Each fixed plate 7 has a connecting rope 8 attached to its upper surface. One end of each connecting rope 8 is connected to a hook 9. The lifting mechanism 1 includes two support plates 101. One side of each support plate 101 is connected to the first chute pipe 2. The bottom surface of each support plate 101 is connected to a reinforcing plate 110. One side of each reinforcing plate 110 is connected to the first chute pipe 2. The upper surface of each support plate 101 is connected to a vertical plate 102. The side of each vertical plate 102 that is close to each other is inlaid with a bearing 103. The inner ring of each bearing 103 is connected to a connecting rod 104. The end of each connecting rod 104 that is close to each other is connected to a rotating roller 105. This not only greatly increases the strength of the support plate 101, but also makes it easier for people to install the equipment.
[0026] The outer surface of the rotating roller 105 is wound with a steel cable 106. Two baffles 108 are connected to the outer surface of the rotating roller 105. One end of the steel cable 106 is connected to a fixing frame 107. One side of the fixing frame 107 is connected to the third chute pipe 4. A servo motor 109 is installed on the front of one of the vertical plates 102. The output end of the servo motor 109 is connected to one of the connecting rods 104 through a coupling. This not only prevents the steel cable 106 from getting tangled during the winding and unwinding process, but also makes it convenient for people to adjust the height of the chute, so that the equipment can meet the needs of carriages of different heights.
[0027] The working principle of this utility model is as follows: First, the equipment can be installed in the usage position using hooks 9. Then, the first chute 2, the second chute 3, and the third chute 4 are nested in sequence. The maximum extension stroke is limited by the limiting plate 5, and the rubber pad 6 can prevent the pipe body from colliding during operation. Then, the servo motor 109 can be started according to the height of the carriage. The servo motor 109 transmits to the connecting rod 104 through the coupling, driving the rotating roller 105 to rotate, causing the steel cable 106 wound on its surface to be wound up and down. The steel cable 106 is connected to the third chute 4 through the fixing frame 107. When the steel cable 106 is tightened, the third chute 4 rises and drives the second chute 3 to contract; when it is loosened, the pipe body naturally extends due to gravity. The baffle 108 can prevent the steel cable 106 from deviating during the winding and unwinding process. Finally, the powder enters from the first chute 2 and is transported to the carriage in sequence through the second chute 3 and the third chute 4.
