A hyperstatic mesh beam device is arranged between the screen plates on both sides of the screen box, and multiple main beams are connected by at least one hyperstatic support plate to form an enclosure. Vibrators are respectively added to the excitation transmission shafts on both sides of the hyperstatic support plate, and no I-beam or rectangular steel is required as the support of the main beam vibrator. The supporting volume of the vibrator is reduced, the vibration weight of the vibrating screen is reduced, and the motion accuracy of the rotating body is improved. The vibrating screen body has a simple structure, increased reliability, improved comprehensive performance, and stable vibration. It can meet the process requirements of the large-scale vibrating screen excitation device and improve the production efficiency of the single vibrating screen. It has wide practicality in the fields of coal, metallurgy, chemical industry, and environmental protection.
Description
One, technical field
