Planet gear driving type screening device

Abstract

The invention discloses a planet gear driving type screening device. The planet gear driving type screening device is characterized in that the device comprises a pedestal, planet gear bases, a sieve plate, planet gear driving mechanisms, a sliding groove, a sliding bar and a driving disk; the pedestal is used for fixing a screening device body on the ground; the planet gear bases are arranged on the two sides of one end of the pedestal; the sieve plate is arranged above the screening device body and used for screening materials; each planet gear driving mechanism is arranged on one side of the corresponding planet gear base and used for driving the sieve plate to move; the sliding groove is located in the other end of the sieve plate and used for allowing a finger pin of the sliding bar to slide therein; the sliding bar is connected with the sliding groove through one section of the finger pin and can slide in the sliding groove through the finger pin, and the sliding groove is formed in the other end of the sliding bar; the sliding bar is hinged to the center of the circle of the driving disk, and the finger pin arranged on the driving disk slides in the sliding groove of the sliding bar, so that the sliding bar is driven to rotate around the center of the circle of the driving disk. The screening device is simple and compact in structure, large in operation space, flexible in sieve plate motion, and capable of improving work quality and efficiency.

Description

technical field [0001] The invention relates to the field of screening devices, in particular to a planetary wheel driven screening device. Background technique [0002] At present, in many sand fields, the sand extracted from the river is directly loaded, unloaded and sold with a forklift, and the river sand is basically not classified and screened before being sold. Screening is also carried out during construction on the construction site, which not only takes up a lot of Manpower, but also increased production costs. [0003] The screening machines sold on the existing market are generally only used in construction sites, and are rarely used in sand fields; moreover, these screening machines are usually manually operated and simply mechanically vibrated to screen sand. The extension machine fails to sieve sands of different thicknesses, which not only wastes time, but also increases labor costs. [0004] To sum up, the existing screening devices mainly have defects suc...
