[0002] Mortar is the bonding material used for bricklaying in construction. It is composed of a certain proportion of sand and binding materials (cement, lime paste, clay, etc.) and water. It is also called mortar and is an indispensable material in the construction field.

[0003] At present, the existing mortar screening device (such as patent number: CN220573991U) discloses a premixed mortar screening device. Through the cooperation of a main motor, a reciprocating screw, a base, a fixed plate, a column and a slider, the device can set multiple layers of screening plates with different apertures according to actual needs, thereby improving the screening effect of the mortar raw materials, and also enhancing the screening efficiency of the device, and can flexibly adjust the distance between adjacent screening plates.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: the two sieve plates were installed horizontally, and the sieve plates could only be moved and adjusted in the vertical direction. During the screening process, the surface of the sieve plates would continuously intercept various impurities, which would accumulate on the surface of the sieve plates, forming layers of sediments, which might affect the screening effect. Utility Model Content

These impurities accumulate on the surface of the sieve plate to form layers of sediments, which may affect the screening effect.

[0007] (2) Technical solution

The deflection angle of the first filter plate and the second filter plate is adjusted. By tilting the first filter plate and the second filter plate, impurities can be effectively prevented from settling and accumulating on the surface, because the inclined surface can prevent impurities from being smoothly deposited, thereby keeping the surface clean.

[0020] The embodiment of the present application provides a premixed mortar screening device, which effectively solves the problem that the screen plate can only be moved and adjusted in the vertical direction. During the screening process, the surface of the screen plate will continuously intercept various impurities, and these impurities accumulate on the surface of the screen plate to form layers of sediments. These sediments may affect the screening effect. By pulling the top end of the buffer rod, the buffer rod is forced to retract and retract inside the fixed frame. At the same time, the guide slide exerts a pulling force on one end of the second filter plate, so that the second filter plate rotates around the connecting seat at one end of the first filter plate, and the deflection angle of the first filter plate and the second filter plate is adjusted. By tilting the first filter plate and the second filter plate, impurities can be effectively prevented from settling and accumulating on the surface, because the inclined surface can prevent impurities from being smoothly deposited, thereby keeping the surface clean. At the same time, the inclination angle of the first filter plate and the second filter plate can be flexibly adjusted to adjust the screening speed. Example

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the sieve plate can only be moved and adjusted in the vertical direction. During the screening process, the surface of the sieve plate will continuously intercept various impurities. These impurities accumulate on the surface of the sieve plate to form layers of sediments. These sediments may affect the screening effect. The overall idea is as follows:

The filter screen 15 is fixedly mounted on the filter screen 15, and the filter screen 15 is fixedly mounted on the filter screen 15. The filter screen 15 is fixedly mounted on the filter screen 15, and the filter screen 15 is fixedly mounted on the filter screen 15. The filter screen 15 is fixedly mounted on the filter screen 15, and the filter screen 15 is fixedly mounted on the filter screen 15.

[0023] The guide slide 17 is internally rotatably mounted with two driving rods 22, and the surface of each driving rod 22 is rotatably mounted with a limit slider 21. The outer side of the guide slide 17 is rotatably mounted with a rotating rod 24, and the surface of the rotating rod 24 is fixedly mounted with a collar 23. The side end of the guide slide 17 is fixedly mounted with two fixing blocks 25, and the side end of each fixing block 25 is fixedly mounted with two reset rods 26. The top of the two reset rods 26 is fixedly mounted with a connecting block 27. The top of the connecting block 27 is an arc-shaped design, which is engaged with the surface of the collar 23. By pushing the two connecting blocks 27, the connecting block 27 is allowed to slide on the side end of the guide slide 17, and the connecting block 27 slides and squeezes the top of the reset rod 26, forcing the reset rod 26 to be compressed toward the side end of the fixed block 25. At the same time, the connecting block 27 moves toward the side end of the fixed block 25, and the top of the connecting block 27 is disconnected from the collar 23. The side end of each connecting plate 16 is fixedly mounted with two buffer rods 19.

[0024] Working principle:

[0025] In the first step, the mortar raw material is poured onto the surface of the second filter plate 14, and the mortar raw material is screened through the double filtration of the first filter plate 13 and the second filter plate 14. At the same time, the two connecting blocks 27 are pushed to slide on the side end of the guide slide 17. The connecting block 27 slides and squeezes the top of the reset rod 26, forcing the reset rod 26 to be compressed toward the side end of the fixed block 25. At the same time, the connecting block 27 moves toward the side end of the fixed block 25, and the top of the connecting block 27 is disconnected from the collar 23. By rotating the rotating rod 24, the rotating rod 24 is moved on the guide slide 17. The side end of the slide 17 rotates, and the rotating rod 24 drives the ring 23 to rotate. The end of the rotating rod 24 is connected to the driving rod 22 through a bevel gear, driving the two driving rods 22 to rotate inside the guide slide 17. At the same time, the surface of the driving rod 22 is a threaded design. The driving rod 22 drives the limit slider 21, pushing the two limit sliders 21 to enter the interior of the guide slide 17 first. The top end of the limit slider 21 is disconnected from the side end of the side plate 18, and the guide slide 17 is pulled to slide on the inner wall of the side plate 18.

[0026] The second step is to pull the guide slide 17 at the same time, so that the guide slide 17 slides on the inner wall of the side plate 18, and push the guide slide 17 upward, so that the guide slide 17 drives the connecting plate 16 to move upward, so that the connecting plate 16 moves upward, and the guide slide 17 and the connecting plate 16 rotate with each other. At the same time, the connecting plate 16 is tilted and slides on the side end of the fixed frame 15, and the connecting plate 16 slides on the side end of the fixed frame 15, pulling the top of the buffer rod 19, forcing the buffer rod 19 to retract inside the fixed frame 15. At the same time, the guide slide 17 applies a pulling force to one end of the second filter plate 14, so that the second filter plate 14 rotates around the connecting seat 12 at one end of the first filter plate 13, adjusting the deflection angle of the first filter plate 13 and the second filter plate 14, and the tilted first filter plate 13 and the second filter plate 14 can prevent impurities from precipitating and accumulating on the surface. At the same time, the first filter plate 13 and the second filter plate 14 can flexibly adjust the inclination angle to increase the flexibility of use.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
