Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement mortar technology, specifically a building mortar screening device. Background Technology
[0002] Cement mortar is made of cement, fine aggregate, and water; that is, cement, sand, and water are mixed according to requirements. Cement-mixed mortar, on the other hand, is made of cement, fine aggregate, lime, and water. These are different concepts, with different names and uses. Therefore, when screening building cement mortar materials, a building cement mortar screening device is required.
[0003] When screening sand using a vibrating screen, the inability to set multiple layers prevents the screening process from separating sand of different particle sizes as needed. This necessitates the use of multiple screening devices to separate sand of varying sizes, increasing equipment costs, labor intensity, and reducing the screening efficiency of mortar raw material sand.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figures 1 to 4 As shown, a mortar screening device includes a housing 1, a guide plate 4, a screening box 5, a screening mesh 8, a screening mesh 9, a vibrating structure 10, and a lifting structure 12. The top of the housing 1 is open. The screening box 5 moves within the housing 1. The housing 1 and the screening box 5 work together to screen mortar raw materials. Screening mesh 8 is inclined and fixedly connected within the screening box 5. Screening mesh 9 is also inclined and fixedly connected within the screening box 5, located below screening mesh 8. The mesh size of screening mesh 8 is larger than that of screening mesh 9. The discharge port 7 is lower than the discharge port 2. The lowest end of screening mesh 8 connects to discharge port 2, and the lowest end of screening mesh 9 connects to discharge port 3. When the screening box 5 is inside the housing 1, it is a closed space. During the screening process... The screening box 5 is a closed structure, which can reduce the amount of dust raised in the air during the screening of mortar raw materials. The screening box 5 has a discharge port 2 6 at one end and a discharge port 3 7 at the other end. The discharge port 2 6 and discharge port 3 7 are sealed by the box wall of the box body 1. The vibration structure 10 is located on both sides of the screening box 5. At the same time, the screening screen 1 8 and screening screen 2 9 are used in conjunction with the vibration structure 10 to screen the mortar raw materials in multiple stages. The lifting structure 12 is located between the vibration structure 10 and the box body 1. After screening, the screening box 5 is pushed out of the box body 1 by the lifting structure 12. The guide plate 4 is fixedly connected to both ends of the box body 1. The screened mortar raw materials are discharged through the guide plate 4 through the discharge port 2 6 and discharge port 3 7.
[0028] The vibrating structure 10 includes a fixed plate 101, which is fixedly connected to both sides of the screening box 5. Elastic supports 102 are fixedly connected to the bottom ends of the two fixed plates 101. Movable plates 103 are fixedly connected to the bottom of the two elastic supports 102. A vibrator 104 is fixedly connected between the two movable plates 103 and the fixed plates 101. When screening mortar raw materials, the movable plates 103 are fixed to the lifting structure 12. Simultaneously, the elastic supports 102 and the vibrator 104 work together to cause the screening box 5 to vibrate within the box. During the vibration process, the mortar raw materials in the screening box 5 are vibrated. Furthermore, in conjunction with screening mesh 8 and screening mesh 9, the mortar raw materials are screened multiple times, effectively reducing workload and improving the screening efficiency of the mortar raw materials.
[0029] The lifting structure 12 includes two fixed plates 121, which are fixedly connected to both sides of the box body 1. Electric telescopic rods 122 are fixedly connected to both ends of the top of the two fixed plates 121. The electric telescopic rods 122 are three-section telescopic rods, and their tops are fixedly connected to the bottom of the vibrating structure 10. After the mortar raw materials are screened, the screening box 5 is pushed out of the box body by the electric telescopic rods 1212 in conjunction with the movable plate 103. When the first section of the electric telescopic rod 122 rises to its maximum position... When the discharge port 26 connects with the guide plate 4 at one end of the box 1, the mortar material on the top of the screening screen 7 is discharged. Then, the second movable rod of the electric telescopic rod 122 rises, and the discharge port 37 connects with the guide plate 4 at the other end of the box 1, so that the mortar material on the screening screen 29 is discharged. The mortar material screened by the screening screen 29 is discharged through the discharge port 2 at the bottom of the box 1, thus completing the screening of the mortar material. In addition, the bottom of the box 1 is a sloping structure to avoid the mortar material remaining in the box and being difficult to clean.
