Please refer to fig. 1-5:
example 1: a sand screening device for premixed mortar comprises a device main body 1, a feeding funnel 2 is inserted into the inner surface of the device main body 1, four stabilizing supports 3 are fixedly installed on the inner surface of the top of the device main body 1, first filter plates 4 are fixedly installed on the outer surfaces of the four stabilizing supports 3, a second filter plate 5 is movably connected to the inner surface of the device main body 1, a baffle 6 is welded to the outer surface of the right side of the second filter plate 5, a telescopic box 7 is fixedly installed on the inner surface of the left side of the device main body 1, springs 8 are fixedly installed on the inner surface of the telescopic box 7, an L-shaped support rod 9 is movably connected to the inner surface of the telescopic box 7, materials are placed into the feeding funnel 2, then the materials are filtered by the first filter plates 4, then the materials fall onto a second layer of filter plates for secondary filtering, then a more delicate filtering effect is achieved, a motor 12 is opened, and the motor 12 drives a swing rod 13 to rotate, the oscillating bar 13 drives the annular frame 14 to move left and right, the annular frame 14 drives the L-shaped support rod 9 to move left and right, and then drives the second filter plate 5 to move left and right, so that the effect of vibration screening is achieved, and the clamping stagnation is not easy to occur during screening.
Example 2: the internal surface swing joint of device main part 1 has fine material collecting box 16, the right side external fixed surface of fine material collecting box 16 installs handle 17, the internal fixed surface of device main part 1 installs loading board 18, the internal fixed surface of loading board 18 installs a plurality of gyro wheel 19, drop to inside fine material collecting box 16 through thin material, then reach certain degree after the removal of handle 17, handle 17 will drive fine material collecting box 16 and remove to the right side, then reach the effect of taking out the fine material that will screen, the setting of loading board 18 is for stable support fine material collecting box 16, the setting of gyro wheel 19 is for reducing frictional force, make inside the convenient device that shifts out of fine material collecting box 16, thereby reached the effect that conveniently takes out the fine material.
Wherein the motor 12 is of type Y90S-6.
The working principle is as follows: this sand screening plant for ready-mixed mortar need place the ready-mixed mortar raw materials inside feed hopper 2 in the in-service use of reality, then will drop under the effect of gravity and carry out the primary screening to the raw materials on first filter plate 4, what the primary screening was gone on is non-vibrations screening, main aim at with the building stones and the sand preliminary separation of large granule. The stabilizing frame 3 is used for stably connecting and supporting the first filter plate 4, and then the filtered raw material falls to the top position of the second filter plate 5 for secondary screening.
At this moment, the rotation of the motor 12 will drive the swing rod 13 to rotate, the swing rod 13 will drive the annular frame 14 to move left and right, the annular frame 14 will drive the linkage rod 15 to move left and right, the linkage rod 15 will drive the second filter plate 5 to move left and right, the second filter plate 5 drives the L-shaped support rod 9 to move left and right, the L-shaped support rod 9 will extrude the spring 8, the effect of stably extending and retracting the L-shaped support rod 9 is achieved, and therefore the second filter plate 5 can move left and right under the acting force of the motor 12 and the spring 8, so that the effect of vibration screening is achieved. The portable reciprocating sieve of prior art selects more and provides vibrations with the eccentric disc, and this vibration direction that just leads to the reciprocating sieve is the annular, and the vibration direction is the variety, consequently needs all-round fixed reciprocating sieve on the one hand, and on the other hand also need restrain the amplitude, avoids the reciprocating sieve to break away from fixing device, causes the potential safety hazard. After the vibration sieve is improved, left-right vibration in the horizontal direction is adopted, and the fixed type can be realized only by mainly fixing the horizontal direction of the vibration sieve in a reverse direction, so that the fixing difficulty is obviously reduced compared with the existing eccentric disc type vibration. In addition, because the vibration directions of the utility model are relatively uniform, even if the amplitude vibration frequency is properly improved, the effective fixation can be realized by reinforcing the horizontal direction fixation mode, and the screening efficiency can be improved.
After the second filter plate 5 is vibrated and screened, the larger raw material can drop into the coarse material collecting box 11, and the screened thinner raw material can drop into the fine material collecting box 16 under the action of gravity. Thereby achieving the purpose of screening the raw materials for many times. Then when collecting to a certain extent, pulling handle 17, handle 17 will drive fine material collecting box 16 and move to the right side, then makes fine material collecting box 16 move on gyro wheel 19, reaches the effect of conveniently collecting the material after the screening. The fine sand material of collection is transported through fine material collecting box 16, and it is convenient to transport on the one hand, and on the other hand also can effectively avoid flying upward at transportation in the mode of adding the lid apron.
