Description
Technical Field
[0001] This utility model relates to the field of coal tipping basket technology, and in particular to a pneumatically powered coal tipping basket. Background Technology
[0002] In the coal mining and processing industry, the process of transferring coal from the underground mining face to the surface storage bin, and from the conveyor belt to the subsequent sorting equipment, relies on connecting equipment to achieve a continuous operation of "transportation-turning-unloading". The coal tipping hopper is a key transition device in this process, used to connect the conveyor belt with downstream equipment (such as chutes, sorting machines, and mine cars). Especially in the underground coal mine operation scenario, due to factors such as narrow space, the presence of flammable and explosive gases such as methane, and strict safety standards, the safety, explosion-proofness, ease of operation, and unloading efficiency of the coal tipping equipment directly determine the safety level and production efficiency of coal transfer, and is of great significance for reducing the labor intensity of miners and reducing resource waste. The existing pneumatic coal tipping hopper has several drawbacks. Before welding or installing the dedicated platform, cleaning the slag in the longwall mining face roadway requires 2-3 people working together for each unloading operation. The coal density is also high. Furthermore, the traditional coal tipping hopper is mostly flat-bottomed, and the residual amount after each unloading can reach 5% to 10%, requiring additional manual cleaning and increasing ineffective labor. Therefore, the above-mentioned technical problems need to be solved. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pneumatically powered coal tipping basket.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pneumatically powered coal tipping hopper, comprising a support frame, conveying mechanisms installed at both ends above the support frame, fixed plates installed at equal intervals on both sides between the conveying mechanisms, support rollers installed at an incline between the fixed plates, and a material guiding mechanism installed on the support frame on one side of the fixed plate by bolts, and a tipping mechanism installed above the material guiding mechanism.
[0005] Preferably, the conveying mechanism includes fixed seats that are bolted to each other at both ends above the support frame, and a conveying roller is rotatably mounted between the fixed seats, with a conveyor belt sleeved on the conveying roller.
[0006] Preferably, a positioning plate is bolted to one end of the support frame, and a drive motor is mounted on the positioning plate. The output end of the drive motor passes through the positioning plate and is coaxially fixed to one end of the conveying roller.
[0007] Preferably, the material guiding mechanism includes a coal retaining plate bolted to one side of the support frame, a support plate horizontally fixed below the coal retaining plate, and an inclined material guiding plate fixed to the upper end of the coal retaining plate toward the conveyor belt.
[0008] Preferably, the material turning mechanism includes a lifting anchor cable installed at the top of the canopy, a pneumatic chain hoist installed at the lower end of the lifting anchor cable via a hook, a scoop installed on the support plate of the coal retaining plate below the pneumatic chain hoist, hinge blocks hinged to both sides of the scoop, a connecting rope fixed between the hinge blocks, and the middle part of the connecting rope connected to the telescopic end of the pneumatic chain hoist via a hook.
[0009] Preferably, a guide block is fixed inside the hopper near the coal retaining plate, and the other side of the guide block has an inclined angle.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of pneumatic chain hoist, connecting rope, and skip, facilitates the tipping and unloading of the skip, improving the convenience and efficiency of the unloading operation. This enables a single person to efficiently complete the function of cleaning and unloading slag in the fully mechanized mining face roadway. Furthermore, through the cooperation of the inclined guide block and the skip, it is easy to avoid coal accumulation and residue in the flat-bottomed skip, reducing the amount of residue in a single unloading and improving the thoroughness of unloading. This also enables the reduction of additional manual cleaning steps and ineffective labor. Ultimately, it solves the problems of traditional coal tipping skips requiring multiple people to operate, high labor costs, and the flat-bottom design leading to a lot of residue during unloading and requiring additional manual cleaning.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0013] Example: See Figures 1 to 4 This utility model discloses a pneumatically powered coal tipping hopper, comprising a support frame 1, conveying mechanisms mounted at both ends of the support frame 1, fixed plates 4 equidistantly mounted on both sides between the conveying mechanisms, and support rollers rotatably mounted between the fixed plates 4. A material guiding mechanism is bolted to the support frame 1 on one side of the fixed plate 4, and a tipping mechanism is mounted above the material guiding mechanism. The support frame 1, conveying mechanisms, fixed plates 4, support rollers, material guiding mechanism, and tipping mechanism facilitate the construction of the overall frame of the pneumatically powered coal tipping hopper, providing a structural foundation for coal conveying, guiding, and unloading operations. The conveying mechanism includes components bolted to each other... At both ends of the support frame 1, there are fixed seats 2. Conveying rollers 3 are rotatably installed between the fixed seats 2. Conveyor belts 5 are fitted on the conveying rollers 3. The fixed seats 2, conveying rollers 3, and conveyor belts 5 form a coal conveying carrier, providing a stable carrying and conveying channel for coal. A positioning plate is bolted to one end of the support frame 1. A drive motor 6 is installed on the positioning plate. The output end of the drive motor 6 passes through the positioning plate and is coaxially fixed to one end of the conveying roller 3. The positioning plate and drive motor 6 provide power to the conveying roller 3, driving the conveying roller 3 to rotate and drive the conveyor belt 5 to run, realizing the automatic conveying of coal.
[0014] In this utility model, the material guiding mechanism includes a coal retaining plate 7 bolted to one side of the support frame 1. A support plate is horizontally fixed below the coal retaining plate 7, and an inclined material guiding plate is fixed to the upper end of the coal retaining plate 7 towards the conveyor belt 5. The coal retaining plate 7, the support plate, and the inclined material guiding plate facilitate the guidance of the coal conveying direction, prevent coal leakage during conveying, and accurately guide the coal to the subsequent tipping components. The tipping mechanism includes a lifting anchor cable installed at the top of the canopy. A pneumatic chain hoist 8 is installed at the lower end of the lifting anchor cable via a hook. A hopper 10 is installed on the support plate of the coal retaining plate 7 below the pneumatic chain hoist 8. Hinged blocks 11 are hinged to both sides of the hopper 10. A connecting rope 9 is fixedly connected between the hinge blocks 11. The middle of the connecting rope 9 is connected to the telescopic end of the pneumatic chain hoist 8 via a hook. Through the lifting anchor cable, pneumatic chain hoist 8, skip 10, hinge blocks 11, and connecting rope 9, the telescopic power of the pneumatic chain hoist 8 can be used to pull the connecting rope 9, causing the skip 10 to rotate around the hinge blocks 11, thus realizing the coal unloading operation. Inside the skip 10, near the coal retaining plate 7, a guide block 12 is fixedly connected. The other side of the guide block 12 has a downward tilt angle. Through the guide block 12 inside the skip 10, the coal inside the skip 10 can be smoothly guided to slide down, avoiding coal residue or blockage inside the skip 10, and ensuring unloading efficiency.
[0015] Working Principle: In the use of this utility model, the lifting anchor cable is first fixed to the top of the ceiling, and then connected to the upper end of the pneumatic chain hoist 8 through a hook to provide suspension support for the entire material turning mechanism, ensuring that the material turning mechanism is stably suspended above the material guiding mechanism. Then, the pneumatic chain hoist 8 provides pneumatic power for turning the material. At the same time, the telescopic end is connected to the middle of the connecting rope 9 through a hook, and then the telescopic action can be achieved by compressed air. In the initial state, the pneumatic chain hoist 8 retracts simultaneously, causing the scoop 10 to move upward. When it moves to a certain height, it approaches the conveyor. When the pneumatic hoist 8 on one side of belt 5 stops moving, the pneumatic hoist 8 on the other side continues to move, causing the skip 10 to tilt to one side through the connecting rope 9 and the hinge block 11, forming a power transmission link of "pneumatic hoist 8 - connecting rope 9 - skip 10". At the same time, a guide block 12 is fixed to the inner wall of the skip 10 near the coal retaining plate 7. The guide block 12 is inclined downward at a 30°-45° angle on the side away from the coal retaining plate 7, which helps the coal to slide smoothly when it is turned over, and avoids coal residue in the skip 10.
[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
