Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in figures 1-2, a two-vibration explosion-proof straight row sieve, wherein the both sides of vibration frame 4 are fixed with explosion-proof vibrating motor 7, and this vibration frame 4 is fixed in on support 1 through damping spring 2, and reel 5 is fixed on this vibration frame 4 and its upper portion fixed dust cover 6, hopper 3 under the lower part is fixed, and the slope of discharge gate 8 sets up hopper 3's lower extreme down install rack 10 in reel 5, ultrasonic wave vibration head 12 vertical fixation is in the lower part of this rack 10, and screen cloth 11 is fixed on the upper portion of this rack 10, and bin outlet 9 sets up on the lateral wall of reel 5 and is in the upper portion of screen cloth 11, this straight row sieve peripheral hardware explosion-proof ultrasonic power supply 17, ultrasonic wave vibration head 12 through the electric wire with explosion-proof ultrasonic power supply 17 electric connection. The vibration source of the direct vent screen is an explosion-proof vibration motor, and the ultrasonic power supply is an explosion-proof ultrasonic power supply so as to avoid the dust explosion danger caused by sparks. The central axes of the two explosion-proof vibration motors 7 are intersected, the rotation motion of the explosion-proof vibration motors 7 is changed into horizontal, vertical, inclined and centrifugal multi-acting force superposition by using the phase angles of two groups of eccentric blocks (unbalanced eccentric blocks) at the upper end and the lower end of the shaft of the explosion-proof vibration motors 7 and the intersection angle between the two motors, and then the acting force is transmitted to the screen 11, thereby achieving the purpose of screening. The staff can reach the size of change exciting force and the motion trail of material through changing the phase angle and the weight of upper and lower eccentric blocks on the explosion-proof vibrating motor 7.

The screen frame 5 and the dust cover 6 are fixedly connected through the binding rings, and the screen frame is convenient to disassemble and assemble quickly.
