Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, the embodiment is a large FX wind power dry coal separator, the model is FX-24, and the large FX wind power dry coal separator comprises a machine base 1, a rotary crossbeam 2, a four-bar linkage 3, a driving shaft 4, a driven shaft 5, a main driving connecting rod 6, a duplex bearing seat 7, a separating bed 8, a balancing weight 9 and the like. A rotary girder 2 is arranged on a machine base 1, a four-bar mechanism 3 is arranged at two ends of the rotary girder 2, the upper end of the four-bar mechanism 3 is hinged with two ends of the bottom of a bed selector 8 (shown in figures 3, 4 and 5), and the length-width ratio of the bed selector 8 is 2.66, preferably 7920 mm in length and 2965 mm in width.

The middle part of the rotary girder 2 is provided with a driving shaft 4 and a driven shaft 5 (shown in figures 6 and 7), the driving shaft 4 and the driven shaft 5 are arranged in parallel, two ends of the driving shaft 4 and the driven shaft 5 are respectively arranged in two shaft holes of the duplex bearing seat 7, the axes of the two shaft holes of the duplex bearing seat 7 are parallel, a bearing is arranged in the shaft hole, and the duplex bearing seat 7 is connected with the rotary girder 2 through a bolt. The driving ends of the driving shaft 4 and the driven shaft 5 are provided with a driving gear and a driven gear which are meshed. The main driving connecting rod 6 is of a large-small head structure, a large-head shaft hole of the main driving connecting rod 6 is a driving shaft hole, a bearing is installed in the driving shaft hole, the driving shaft 5 is installed in the bearing, a small head of the main driving connecting rod 6 is a driven shaft hole, and the driven shaft hole is hinged with the sorting bed 8 through a pin shaft.
