Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a construction waste screening and crushing device. Background Art

[0002] The construction waste screening and crushing device is a mechanical device specially used for processing construction waste. The device integrates screening and crushing functions and can effectively crush construction waste. And according to the crushing conditions of construction waste, the screening device can be used to screen the crushed construction waste according to particle size;

[0003] According to the structural setting of the screening and crushing device, some construction waste screening and crushing devices will adopt the method of combining a crusher and a drum screen structure to realize the crushing and screening of construction waste, and the drum screen is installed on the bracket of the drum screen through multiple supporting wheels and limiting wheels. In addition, due to the need to achieve better screening effect and ensure the normal discharge of the screened material, the installation of the drum screen will be set obliquely, and the number of supporting wheels supporting the drum screen is large. Each supporting wheel needs to be adjusted separately, which makes synchronous adjustment difficult. In actual operation, due to the mutual influence and restriction between the supporting wheels, it is difficult to achieve accurate height synchronization. When the heights of two supporting wheels at the same horizontal position are inconsistent, the drum screen will become unstable during operation. This instability not only affects the screening efficiency, but may also cause additional wear on the screen and reduce its service life. Long-term vibration and uneven force may also cause structural deformation or even damage of the drum screen, thereby increasing maintenance costs and downtime. Utility Model Content
