Description

Technical Field

[0001] The utility model relates to the technical field of under-screen discharging belt conveyors, and specifically relates to an under-screen discharging belt conveyor. Background Art

[0002] The undersize discharge belt conveyor is a widely used conveying device. It first screens the material through a sieving machine, which classifies the material into coarse and fine particles. The sieving machine then works in conjunction with the undersize discharge belt conveyor, allowing larger particles to pass through the sieve and fall onto the undersize discharge belt conveyor. The drive unit then drives the belt conveyor, transporting the material to its destination. This provides stable conveying and discharge performance, improving processing efficiency and product quality.

[0003] When using an undersize conveyor, material falling onto the conveyor surface raises dust, which can easily enter the conveyor's shaft. Long-term operation can cause wear on the belt and shaft, significantly reducing their service life and requiring regular maintenance and replacement, which increases maintenance costs. Furthermore, undersize conveyors generate dust during the production process, which has a certain impact on the production environment. Therefore, we propose an undersize conveyor that ensures the durability and stability of the equipment. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of the present invention are: when using the under-screen discharging belt conveyor, the conveyor belt is improved, and rubber skirts are symmetrically arranged on the surface. Due to the tensile properties of rubber, it can be stretched together with the conveyor belt to provide a shielding function. At the same time, a discharge structure is provided to cooperate with the rubber skirt for shielding. A flange hole is provided on the top of the discharge structure, which is convenient for connection with the discharge port of the screening machine. By shielding the discharge process, dust can be effectively shielded and prevented from entering the main body of the belt conveyor, thereby ensuring the cleanliness of the production environment and product quality. The dust is then extracted by the exhaust structure. By turning on the power of the exhaust fan and turning on the lowest gear of wind power, the extraction of dust can be ensured, while avoiding the adverse effects of excessive wind force on production. At the same time, this operation method is simple and convenient, which can extend the service life of the belt and reduce maintenance costs and downtime. BRIEF DESCRIPTION OF THE DRAWINGS
