technical field

The utility model relates to the field of conveyors, in particular to a feeding mechanism for continuously sealing and conveying materials.

Background technique

With the continuous and rapid development of society, there are more and more kinds of domestic garbage, the pollution and damage of urban living garbage to the environment are becoming more and more serious, and people's efforts to deal with garbage are also constantly strengthening. Household garbage includes all kinds of solid waste. In the process of garbage treatment or recycling, it is an indispensable link to transport it to designated areas for processing.

In order to prevent domestic waste from leaking during transportation or causing damage to the working environment due to flying due to vibration, sealed transportation is currently used to solve such problems. However, when conveying domestic waste, it is easy to cause blockage during the feeding process, especially when the accumulation of various domestic wastes causes problems such as bridging and bonding. In this case, it is more difficult to discharge smoothly; Poor, seriously affecting the working environment and work efficiency. Therefore, there is an urgent need to design a feeding mechanism that can continuously seal and convey domestic waste to solve the problems that occur during the transportation of domestic waste.
