Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-4, in the embodiment, the discharging device of the cement mill, which is not easy to block, includes a tube body 1, a screen mechanism is movably disposed inside the tube body 1, an installation cavity 3 is disposed on an inner wall of the tube body 1, a plurality of driving mechanisms are disposed in the installation cavity 3, each driving mechanism includes a motor 31, the motor 31 is fixedly disposed inside the installation cavity 3, an output shaft of the motor 31 is horizontally disposed and coaxially connected with a rotating shaft, an elliptical cam 32 extending in a vertical direction is fixedly connected to the rotating shaft, a long square frame 33 is sleeved outside the elliptical cam 32, a maximum distance from a circle center of the elliptical cam 32 to an outer side of the elliptical cam is smaller than a length of the long square frame 33, an upper end of the long square frame 33 is fixedly connected with a transmission rod 34, the transmission rod 34 is detachably connected as an outer edge portion of the screen mechanism at an output end of the driving mechanism, so that the transmission rod 34 transmits a movement track of the long square frame 33 to the screen mechanism.

The device drives a strip square frame 33 to move up and down at the horizontal height through a rotary elliptical cam 32, so that a screen mechanism moves up and down, the screen mechanism comprises a coarse screen 21 and a fine screen 2 which are sequentially arranged from top to bottom, the screen mechanism is the prior art, a part of transmission rods 34 are detachably connected with the outer edge part of the coarse screen 21, preferably, transmission rods 34 are respectively arranged on two sides of the inner wall of a pipe body 1 and are connected with the coarse screen 21, a part of transmission rods 34 are detachably connected with the outer edge part of the fine screen 2, preferably, one transmission rod 34 is respectively arranged on two sides of the inner wall of the pipe body 1 and is connected with the fine screen 2, and the coarse screen 21 and the fine screen 2 can stably move up and down.

Further, one side of the upper end surface of the mounting cavity 3, which is close to the inner wall of the pipe body 1, is higher than one side of the upper end surface of the mounting cavity, which is far away from the inner wall of the pipe body 1, and the upper end surface of the mounting cavity is obliquely arranged downwards.

Because the upper end face of the mounting cavity 3 can contain part of falling dust, the dust is prevented from being accumulated on the upper end face and obliquely moves downwards, so that the dust can slide to the discharge hole conveniently.

Furthermore, the included angle between the upper end surface of the mounting cavity 3 and the horizontal plane is thirty degrees.

When the included angle between the upper end surface of the mounting cavity 3 and the horizontal plane is too large, the movement track of the strip-shaped frame 33 may be affected, and when the included angle is too small, the dust may not slide smoothly, and part of the dust still accumulates on the upper end surface.

Further, the outer edge part of the screen mechanism is provided with square holes, the upper end of the transmission rod 34 is a screw rod, the part of the transmission rod 34 inserted into the outer edge is a square rod, the square rod is matched with the square holes, the transmission rod 34 is positioned at the lower end of the square holes, the outer diameter of the transmission rod is slightly larger than the square holes, and the transmission rod cannot pass through the square holes.

The application provides a preferred embodiment, peg graft to square downthehole through square pole, make transfer line 34 unable rotation, the angle of rectangular square frame 33 can not change, thereby can normally drive rectangular square frame 33 when ensuring that oval cam 32 is rotatory, change its movement track, set up square pole lower part external diameter and be slightly greater than the quad slit, restriction screen cloth downstream, circular screw rod and nut cooperation restriction screen cloth upward movement, so that the screen cloth can with transfer line 34 fixed connection, convenient to detach makes later maintenance simultaneously, it is convenient to change the screen cloth.

Further, inside motor 31 passed through bearing plate fixed mounting to installation cavity 3, fixed mounting has support bearing 35 on the bearing plate, and support bearing 35 cover is established in motor 31's output shaft outside to provide the holding power.

When the device is used, the output shaft of the motor 31 bears the weight of the transmission rod 34 and the screen, and the support bearing 35 is arranged to provide support force for the transmission rod and the screen, so that the abrasion at the position is reduced, and the service life of the assembly is guaranteed to a certain extent.

The working principle of the above embodiment is as follows:

material that mill processing was accomplished falls to coarse screen 21 from the top, carry out the screening for the first time, continue to fall to fine mesh screen 2 again, carry out the screening for the second time after, can follow the ejection of compact of below discharge gate department, because the discharge gate does not have other subassemblies that set up, avoid fixed protection casing in the traditional design, cause the inconvenient problem of ejection of compact, the device is through pivoted elliptical cam 32, drive transfer line 34 and carry out up-and-down motion, thereby drive screen cloth mechanism and carry out up-and-down motion, can the adhesion part material on avoiding the horizontal fagging in traditional design, after one-time processing is accomplished, can stop on horizontal fagging for a long time, probably cause extravagant problem.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
