Description

Technical Field

[0001] The utility model relates to the technical field of material distribution, in particular to a two-side material distribution device. Background Art

[0002] The distribution chute is a device used to transport and distribute materials in the mining, coal, metallurgy and other industries. In mines, coal preparation plants, and metallurgical process systems, chutes play the role of connecting different process equipment and transporting and distributing materials. The distribution chute focuses on diverting materials to meet the needs of different production processes. For example, materials are distributed to the two vibrating screens below in equal proportions. Currently, most of the distribution chutes on the market simply use a steel plate welded distribution chute or flap valve to feed the two vibrating screens. There are many problems. The simple welded distribution chute is difficult to ensure that the amount of material on the two vibrating screens is consistent. There is often a large difference, which affects the screening efficiency of the vibrating screen. The flap valve is very inconvenient to adjust, and the wearing parts inside are difficult to replace. Therefore, the company specially developed this project and proposed a two-side distribution device to solve the above problems. Utility Model Content

[0017] See also Figure 1-2The utility model provides a technical solution: a two-side material distribution device, including a walking trolley 7, a material distribution chute 6 and a rail chassis 9. The material distribution chute 6 is arranged on the walking trolley 7, and the walking trolley 7 is in rolling contact with the rail chassis 9. The material distribution chute 6 is arranged in an inverted Y-shaped structure. The upper end of the material distribution chute 6 is provided with a feed port 5, and the lower end of the material distribution chute 6 is provided with a discharge port 10. There are two discharge ports 10. The material distribution chute 6 divides the material into two flow channels, so as to realize feeding to two vibrating screens, which can greatly improve the screening efficiency of the vibrating screen. The material port 10 passes through the bottom of the traveling trolley 7 and corresponds to the weighing chute 1 respectively. The weighing chute 1 is used to receive the material discharged from the distribution chute 6 respectively; a lower base frame 3 is provided under the weighing chute 1, and a weighing sensor 2 is provided between the lower base frame 3 and the weighing chute 1. The lower base frame 3 is used to fix the weighing sensor 2 to ensure the stability of the weighing sensor 2 and the accuracy of the measurement. The weighing sensor 2 is electrically connected to the electronic control system. The weighing sensor 2 is used to detect the weight of the material in the weighing chute 1 and output the weight signal to the electronic control system.

[0018] Guide wheels 4 are respectively provided at the four corners of the traveling trolley 7, and rails 8 are provided on the upper surface of the rail frame 9. The guide wheels 4 are in rolling contact with the rails 8. A drive motor 12 is provided on the bottom surface of the traveling trolley 7. The drive motor 12 is electrically connected to the electronic control system. The electronic control system receives the weight signal of the weighing sensor 2 and calculates the weight difference of the materials in the two weighing chutes 1. When the weight difference is greater than the set value, the drive motor 12 of the traveling trolley 7 is controlled to rotate in the opposite direction, so that the distribution chute 6 moves in the direction of the side with smaller weight, thereby adjusting the distribution state of the material.

[0019] The steel rail 8 is a rectangular rail or a circular guide rail to provide high-precision linear guidance. The material of the steel rail 8 is wear-resistant high-strength steel to improve the durability and impact resistance of the device.

[0020] Stoppers 11 are provided at both ends of the rail 8 , which restrict the trolley 7 and prevent it from detaching from the rail 8 , thereby ensuring that the structure of the trolley 7 is safe and reliable.

[0021] The lower chassis 3 is made of stainless steel or carbon steel, and its structure has corrosion resistance and high strength, and is suitable for harsh environments such as mining, chemical industry, and metallurgy.

[0022] The traveling trolley 7 is designed as a hollow structure, the material distribution chute 6 is welded to the traveling trolley 7, and a reinforcing plate rib 14 is provided between the material distribution chute 6 and the traveling trolley 7. The reinforcing plate rib 14 is used to increase the strength of the connection structure and to increase the ability to bear the impact of materials.

[0023] During the working process, the upstream belt conveyor or chute transports the material into the distribution chute 6, and the material enters the two weighing chutes 1 below from the two discharge ports 10 of the distribution chute 6, and then flows into the downstream equipment. The weighing sensor 2 below the weighing chute 1 transmits the weighing signal to the electronic control system in real time, and the electronic control system performs calculations. If the weight difference between the two sides is greater than the set value, the electronic control system controls the rotation direction of the drive motor 12 on the walking trolley 7, and drives the walking trolley 7 to move a certain set distance toward the weighing chute 1 with lower weight, and then enters the next cycle of weighing judgment. By continuously adjusting the position of the distribution chute 6, the purpose of uniform material distribution is achieved.

[0027] The material distribution chute 6 is mounted on the traveling trolley 7 with bolts to ensure that the chute and the trolley move synchronously.

[0028] The weighing chute 1, the weighing sensor 2 and the lower chassis 3 are sequentially installed below the rail chassis 9.

[0029] Example 3: Optional Variant

[0030] Dual drive structure: A drive motor 12 is installed at each end of the traveling trolley 7 to improve the driving force and response speed of the device.

[0031] Multiple control modes: Multiple operating modes can be preset in the electronic control system, such as "quantitative material distribution mode" and "dynamic balancing mode" to adapt to different material characteristics and production process requirements.

[0032] Intelligent optimization algorithm: The electronic control system can adopt PID control algorithm or fuzzy control algorithm to further optimize the moving path and speed of the walking car 7 and reduce control errors and unnecessary movements.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention.
