Description

Technical Field

The feeding and screening system is mainly composed of a vacuum loader, a screening machine, an equipment frame, etc. Chinese patent CN211649654U discloses a mounting bracket for a vacuum loader. The patent designs a base frame platform, a first bracket component, and a second bracket component to support the vacuum loader. At the same time, the screening machine is placed on the base frame platform to form an upper and lower arrangement structure of the vacuum loader and the screening machine. The defect of this patent is that the first bracket component and the second bracket component have complex structures and high processing costs. In addition, a base frame platform is required to install the first bracket component, which occupies a large area.
