[0003] According to the dust remover for concrete production disclosed in Chinese Patent Publication No. CN215610303U, the dust can be transported into the inside of the dust collecting box through the cooperation of the air extractor and the air pump, and the large-particle and small-particle dust can be screened through the screen plate, which is very convenient. However, the dust remover still has some disadvantages in actual use. Since the top of the dust collecting box is open, the dust discharged from the air outlet will be carried by the flowing air and transported downward. Although the dust can be prevented from diffusing in a large area, the dust cannot be prevented from flowing in a small range, which pollutes the surrounding working environment. In addition, the large-particle dust collected on the screen plate is easily scraped and falls off when the screen plate is pulled out, so as to mix with the small-particle dust after screening. Therefore, the operation mode has some room for improvement, which leads to poor practicability of the existing dust remover for concrete production. CONTENT OF THE INVENTION
