Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, a novel bar screen comprises a vibrating frame 1, a vibration exciter, a spring support, a motor base and a driving motor, wherein a stepped screen bar mounting plate 2 is arranged on the inner side of the vibrating frame 1 along a discharging direction, a row of screen bar mounting holes 3 are arranged on each screen bar mounting plate 2, a taper sleeve 4 is arranged in each screen bar mounting hole 3, a taper hole 41 is arranged in each taper sleeve 4, the bar screen 5 further comprises a screen bar 5, each screen bar 5 comprises a mounting end 51 and a screening end 52, at least one end of each screening end 52 is provided with a first tapered structure 521, each mounting end 51 comprises a limiting section 511, a mounting section 512 and a fastening section 513 which are sequentially arranged, the mounting section 512 is provided with a second tapered structure pointing to the end, the fastening section 513 is provided with an external thread, in a mounting state, the second tapered structure is matched with the taper hole 41 to be sleeved, the fastening section 513 is in threaded connection with a bolt 6, the diameter of the outer ring of the bolt 6 is larger than that of the small taper hole 41, the diameter of the limiting section 511 is larger than the diameter of the large taper end of the taper hole 41. The length of the drogue 4 is not shorter than the length of the mounting section 512. The upper surface of the screen bar 5 is a smooth arc surface, and two side surfaces of the screen bar 5 are flat surfaces. The screen bars 5 are provided with a cavity 53 penetrating left and right along the central axis.
