the utility model provides a vibrating screen, includes frame and last feed bin, the lower extreme rigid coupling of going up the feed bin has the sieve body, the sieve body is all fixed mutually and is had the walking axle about both ends, the terminal rotation in the outside of walking axle links mutually has the walking wheel, the lower extreme of walking wheel all with the top frid inner wall of frame, the left end center stationary phase of sieve body even has the connecting plate, the left side below stationary phase of frame even has the pendulum needle speed reducer, the terminal rigid coupling of output shaft of pendulum needle speed reducer has the sector plate, the rear side of sector plate is provided with the connecting rod, the both sides end of connecting rod all rotates continuously with sector plate and connecting plate respectively through the round pin axle, the lower extreme rigid coupling of sieve body has out the hopper.

Preferably, the upper bin is positioned on the right side above the frame.

Preferably, a vibrating screen is installed at the center of the inside of the screen body.

Preferably, a taper opening is processed at the front end of the feeding bin.

The utility model provides a pair of vibrating screen, beneficial effect lies in:

through the sieve body, the pendulum needle speed reducer, the walking wheel, cooperation between frame and the sector plate, the sieve body is when the preparation, there is certain inclination about, will be followed the upper discharge mouth and screened out vibrations in-process granule is big, when pendulum needle speed reducer drive, rotary motion is to the sector plate, at this moment will drive the sieve body and do the seesaw in the track of frame through the walking wheel, thereby play vibrations effect, will spill from the bottom through the screen cloth through vibrations screen cloth granule is little, the granule will be followed the discharge gate and screened out greatly, and the present case is made the sieve body when the design has certain inclination about, make will follow the upper discharge mouth and be screened out vibrations in-process granule is big, so effectively realize the autosegregation of different granule size materials, the screening efficiency has been promoted greatly.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to figures 1-6: in the embodiment, the vibrating screen comprises a frame 5 and an upper bin 1, wherein the lower end of the upper bin 1 is fixedly connected with a screen body 3, the inner sides of the left and right sides of the front and back ends of the screen body 3 are fixedly connected with walking shafts 11, the outer end of each walking shaft 11 is rotatably connected with a walking wheel 10, the lower ends of the walking wheels 10 are respectively connected with the inner wall of a slot edge above the frame 5, the left end center of the screen body 3 is fixedly connected with a connecting plate 4, the lower side of the left side of the frame 5 is fixedly connected with a swing needle speed reducer 9, the tail end of an output shaft of the swing needle speed reducer 9 is fixedly connected with a sector plate 8, the rear side of the sector plate 8 is provided with a connecting rod 7, the model of the swing needle speed reducer 9 can be determined according to specific use conditions, the tail ends of two sides of the connecting rod 7 are respectively rotatably connected with the sector plate 8 and the connecting plate 4 through hinge pins, the lower end of the screen body 3 is fixedly connected with a discharge hopper 6, the upper bin 1 is positioned on the right above the frame 5, the inner center of the screen body 3 is provided with a vibrating screen 2, the front end of the upper bin 1, and a tapered opening is machined into which can be used as a material discharge opening with larger particles;
