Abstract
The invention discloses a vibration screen. The vibration screen comprises a screen box, supports, springs and screen plates. The screen box is elastically supported on the supports through the springs. The three screen plates are arranged in the screen box in a layering manner. The vibration screen further comprises rotating shafts, transmission belt wheels, a transmission belt, eccentric blocks, a motor, an elastic coupler and a flange plate. The two rotating shafts are rotationally arranged on the screen box. The two ends of each rotating shaft penetrate the screen box and stretch out of the screen box. The two transmission belt wheels are arranged on the two rotating shafts. The transmission belt is wound around the two transmission belt wheels. The flange plate is in threaded connection to one rotating shaft. A rotating shaft of the motor is connected with the flange plate through the elastic coupler. The two eccentric blocks are arranged on the two rotating shafts. The vibration screen is simple in structure, one motor drives two spindles to rotate at the same time, and the moving amplitude of the screen plates is increased. Centrifugal force, acting on the motor, of a vibration exciter can be effectively buffered through the elastic coupler, and the service life of the motor is prolonged.
Description
Technical field:
The present invention relates to a kind of vibrosieve.
Background technology:
In occasions such as rock crushing plants, often use vibrosieve.Existing vibrosieve is mainly made up of screen box, spring, vibrator, main shaft, sieve plate and motor, motor drive shaft, the vibrator being arranged on main shaft rotates with main shaft, the eccentric block of operating produces centrifugal force, screen box is excited to produce the motion of certain amplitude, material produces continuous print sling movement on compass screen surface, thus reaches to screen material and the purpose of classification.
Existing vibrosieve mostly is single shaft transmission, and the momentum that screen box is subject to is little, and sieve plate motion amplitude is little, and the output shaft of the motor in existing vibrosieve is directly connected with main shaft, in motor rotary course, the centrifugal action that vibrator produces reacts on motor, is easily damaged motor.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Summary of the invention:
The present invention is in order to solve the problem of above-mentioned prior art existence and to provide a kind of vibrosieve.
The technical solution adopted in the present invention has: a kind of vibrosieve, including screen box, support, spring and sieve plate, described screen box is supported on support by spring, three pieces of sieve plate layerings are located in screen box, also include rotating shaft, drive pulley, transmission band, eccentric block, motor, yielding coupling and ring flange, axis of rotation described in two is located on screen box, and the two ends of rotating shaft both pass through screen box and stretch in outside screen box, two drive pulleys are located in two rotating shafts, transmission band is set around on two drive pulleys, ring flange is threaded in rotating shaft described in, the rotating shaft of motor is connected with ring flange by yielding coupling, two eccentric blocks are located in two rotating shafts；
Described yielding coupling includes contiguous block, connection dish and connects band, described in two, connection dish is arranged in parallel, some connection bands are fixedly connected between two connection dishes, and two contiguous blocks are respectively welded on two connection dishes, and two contiguous blocks are connected with ring flange and machine shaft respectively.
Further, the described band that connects is bolted to connection with being connected between dish.
There is advantages that
1) present configuration is simple, and a motor drives two rotating shafts to rotate simultaneously, increases the motion amplitude of sieve plate.
2) yielding coupling in the present invention can effectively buffer vibrator and act on the centrifugal force of motor, extends the service life of motor.
Accompanying drawing illustrates:
Fig. 1 is vibrosieve front view of the present invention.
Fig. 2 is vibrosieve left view of the present invention.
Fig. 3 is the structure chart of vibrosieve Elastic shaft coupling of the present invention.
Detailed description of the invention:
The present invention is further illustrated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, one vibrosieve of the present invention, including screen box 11, support 12, spring 13 and sieve plate 14, screen box 11 is elastically supported on support 12 by spring 13, three pieces of sieve plate 14 layerings are located in screen box 11, vibrosieve of the present invention also includes rotating shaft 21, drive pulley 22, transmission band 23, eccentric block 24, motor 25, yielding coupling 26 and ring flange 27, two rotating shafts 21 rotate and are located on screen box 11, and wall stretch in outside screen box 11 before and after two ends both pass through screen box 11 before and after these two rotating shafts 21, two drive pulleys 22 are respectively fixedly connected with in the front end of two rotating shafts 21, transmission band 23 is around being located on two drive pulleys 22.Ring flange 27 is threaded in the rear end of a rotating shaft 21, and the rotating shaft of motor 25 is connected with ring flange 27 by yielding coupling 26, and drives two rotating shafts 21 to rotate, and two eccentric blocks 24 are fixedly connected on the rear end of two rotating shafts 21.The eccentric block 24 in present invention connected mode in rotating shaft 21 is identical with eccentric block connected mode on axle in vibrator in prior art, therefore no longer repeats attachment structure between the eccentric block 24 in the present invention and rotating shaft 21.
Such as Fig. 3, yielding coupling 26 in the present invention includes contiguous block 260, connection dish 261 and connects band 262, two connection dishes 261 are arranged in parallel, and some bands 262 that connect are located between two connection dishes 261, and the every two ends connected with 262 are all fixed connected by bolt and two connection dishes 261.Two contiguous blocks 260 are respectively welded on two connection dishes 261, and wherein a contiguous block 260 is fixing with ring flange 27 is connected, and another contiguous block 260 is connected with motor 25 rotating shaft.Connecting in yielding coupling 26 can effectively buffer vibrator with 262 and act on the centrifugal force of motor, extends the service life of motor.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
