Turning plate type screening device

Abstract

Disclosed is a turning plate type screening device. A screen plate is arranged on a rack of the turning plate type screening device. A vibration motor is arranged on the screen plate. The screen plate is connected with a rotary shaft and is driven by a telescoping cylinder to rotate around the rotary shaft. The rotary shaft is arranged between the vibration motor and the output end of the telescoping cylinder. Compared with the traditional mode that a vibration motor and a telescoping cylinder are located at the same end of a hinged shaft, the turning plate type screening device enables the rotary shaft to be arranged between the vibration motor and the telescoping cylinder, the self-weight of the vibration motor indirectly serves as a counterweight, force at the two ends of the screen plate can be better balanced, impact force generated when the screen plate rotates or returns can be reduced, rotation is more flexible, more power and energy of the motor are saved, and cost is further reduced. Moreover, the vibration motor is arranged at the end, away from the feeding side, of the screen plate so that a feeding screening area can generate a large amplitude and the screening effect is improved. Furthermore, the vibration motor is arranged in the middle in the width direction of the screen plate, so that a certain balance function is achieved, and the screen plate is prevented from tilting to one side in the width direction.

Description

technical field [0001] The invention relates to a screening device, in particular to a flap type screening device. Background technique [0002] With the wide application of commercial concrete in houses, bridges, roads and water conservancy construction projects, the requirements for commercial concrete production equipment are also getting higher and higher. In the process of concrete production, it is necessary to go through the aggregate screening process. The aggregate screening device used today is prone to material jams when sieving aggregates. The aggregates stuck on the sieve plate are not easy to clean and affect the screening. Effect. In order to solve this problem, the patent document with the authorized announcement number of CN202316284U and the authorized announcement date of 2012.7. The vibration damping device, the second vibration damping device, the base, the hydraulic push rod, the upper sieve slat group and the lower sieve slat group are installed on t...
