[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-3 The dry-mix mortar aggregate grading and screening device shown includes a tank body 1, a servo motor 2 disposed on the top of the tank body 1, a rotating shaft 3 connected to the output end of the servo motor 2 and extending downward into the interior of the tank body 1, and a screening assembly disposed inside the tank body 1;

[0028] The screening assembly includes three filter screens 41 installed on the inner wall of the tank body 1 from top to bottom. Two heating plates 42 connected to the rotating shaft 3 are provided on the top of each filter screen 41, and a vibration motor 43 is installed at the bottom of each filter screen 41 for graded screening of the dry-mixed mortar aggregate on the filter screen 41.

[0029] The two heating plates 42 on the top of each filter screen 41 are both tilted and used to stir and screen the dry-mixed mortar aggregate on the filter screen 41 .

[0030] In one embodiment, the three filter screens 41 are evenly spaced apart, wherein the mesh diameter of the filter screen 41 at the top is larger than the mesh diameter of the filter screen 41 at the middle, and the mesh diameter of the filter screen 41 at the middle is larger than the mesh diameter of the filter screen 41 at the bottom, so that the dry-mixed mortar aggregate can be screened three times when falling, thereby improving the screening effect of the dry-mixed mortar aggregate.

[0031] In one embodiment, the end of each heating plate 42 away from the rotating shaft 3 is set to an arc-shaped surface that is compatible with the inner wall of the tank body 1, the bottom of each heating plate 42 is set to a flat surface, and the upper bottom edge of the inclined surface of each heating plate 42 is chamfered to facilitate stirring by the heating plate 42, so that the dry-mixed mortar aggregate can be heated by the heating plate 42 and lifted upward at the same time, thereby quickly breaking up the agglomerated dry-mixed mortar aggregate. The inclination angles of the two heating plates 42 on the top of each filter screen 41 are set in opposite directions, and the inclination angle is set to 20-30 degrees. In accordance with the rotation of the rotating shaft 3, the inclined surface of the heating plate 42 can face the dry-mixed mortar aggregate pile on the filter screen 41, and lift it upward after stirring.

[0032] In one embodiment, a feed pipe 5 is installed on the top of the tank body 1, and the feed pipe 5 is located on one side of the servo motor 2. A discharge pipe 6 is installed at the bottom of the tank body 1. The bottom wall of the tank body 1 and the discharge pipe 6 are funnel-shaped as a whole. Support legs 7 are also installed at the four corners of the bottom of the tank body 1. The discharge pipe 6 is located between the four legs 7, which is convenient for the use of the dry-mixed mortar aggregate grading and screening device. A door panel 8 is installed on the front side of the tank body 1, and the door panel 8 is set to a transparent panel, so that when the dry-mixed mortar aggregate is graded and screened, the staff can check the status inside the tank body 1 at any time. At the same time, after opening the door panel 8, it is convenient for the staff to clean impurities on the filter screen 41.

[0033] The specific implementation method is as follows: when the present invention is in use, the staff directly puts the dry-mixed mortar aggregate that needs to be screened into the tank body 1 through the feed pipe 5, and starts the vibration motor 43 under each filter screen 41, so that each filter screen 41 starts to vibrate. At this time, the dry-mixed mortar aggregate with a particle size smaller than the mesh of the uppermost filter screen 41 can directly fall onto the middle filter screen 41. Similarly, the dry-mixed mortar aggregate with a particle size smaller than the mesh of the middle filter screen 41 can directly fall onto the lowermost filter screen 41, and the dry-mixed mortar aggregate with a particle size smaller than the mesh of the lowermost filter screen 41 can directly fall to the bottom of the tank body 1, that is, the dry-mixed mortar aggregate with a suitable particle size is screened out, and then discharged and collected through the discharge pipe 6, and transferred to the next process, thereby completing the production of dry-mixed mortar;

[0034] While the vibration motor 43 is working, the output end of the servo motor 2 rotates clockwise, driving the rotating shaft 3 to rotate clockwise, further causing the heating plate 42 to rotate clockwise, stirring the dry-mixed mortar aggregate above each filter 41. At the same time, the heating plate 42 generates heat to heat the dry-mixed mortar aggregate, thereby preventing the dry-mixed mortar aggregate from agglomerating, so that the dry-mixed mortar aggregate with a suitable particle size can fall through the three filter screens 41 in sequence and be discharged;

[0035] At the same time, since the heating plate 42 is tilted, the dry-mixed mortar aggregate on the filter screen 41 will be lifted upward, which not only improves the stirring effect of the dry-mixed mortar aggregate, but also further enhances the heating effect of the dry-mixed mortar aggregate, thereby completely breaking up the lumps of dry-mixed mortar aggregate. The arrangement of the three filter screens 41 allows the dry-mixed mortar aggregate to be screened step by step, so that the dry-mixed mortar aggregate with a suitable particle size is discharged through the discharge pipe 6 after passing through the layers of filter screens 41. The screened dry-mixed mortar aggregate has a suitable particle size and a good screening effect.

[0036] When all the dry-mixed mortar aggregates are discharged, the staff can open the door panel 8 and clean the larger impurities on the filter screen 41 out of the tank body 1, so that the tank body 1 can be put into use again.

[0037] This embodiment specifically solves the problem in the prior art that when the current screening device is used to screen dry-mixed mortar aggregates, the dry-mixed mortar aggregates contain moisture, which easily agglomerates in the screening device and ordinary screening devices cannot cope with this situation, resulting in insufficient screening of the dry-mixed mortar aggregates and poor screening effect.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
