Technical Field
[0001] The utility model relates to the technical field of mortar screening, in particular to a mortar screening device. Background Technique
[0002] Mortar is a bonding substance used for bricklaying in construction. It is made by mixing sand and cementitious materials such as cement, lime paste, and clay in a certain proportion with water. It is also called mortar. Commonly used mortars include cement mortar, mixed mortar (also called cement-lime mortar), lime mortar, and clay mortar. When producing mortar, it is necessary to screen the sand to improve the quality of the mortar. Natural sand commonly used in mortar, such as river sand, often contains large impurities such as gravel and mud blocks during the extraction process, and its distribution is uneven, so it needs to be screened.
[0003] When screening mortar, a vibration motor is used to vibrate the screen mesh to screen the mortar. However, relying solely on the vibration motor to screen the mortar, the vibration amplitude is small, which leads to the problem of low screening efficiency. Now, a mortar screening device is proposed. Summary of the Utility Model

The first gear and the second gear are both rotatably connected inside the housing. The screening barrel is rotatably connected inside the housing. When the first gear rotates, it drives the second gear to rotate, and then drives the screening barrel to rotate.
[0010] A further improvement of the technical solution of the utility model is that a limit groove is provided inside the shell, the limit rod is rotatably connected in the limit groove, a first box door is hinged on the shell, a material guide plate is fixedly connected to the inside of the shell, and the screened mortar slides along the material guide plate, thereby facilitating collection.

[0025] Specifically, when the first drive motor 11 operates, it drives the first gear 12 to rotate, thereby driving the second gear 13 and the limiting rod 14 to rotate. Consequently, the screening barrel 15 rotates, driving the mortar inside the screening barrel 15 to shake. As a result, the mortar with smaller particles flows out through the holes of the screening barrel 15. Then, the electric rotating rod 16 is started to drive the stirring plate 17 to rotate synchronously, further agitating the mortar, increasing the number of times the mortar is turned over, and preventing the situation of mortar accumulation. At the same time, the cleaning bristles 18 clean the inner wall of the screening barrel 15, thereby preventing mortar from adhering to the inner wall of the screening barrel 15 and further improving the screening efficiency.
[0026] Embodiment 2
[0027] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the material guiding mechanism 2 includes a housing 21.

A first box door 23 is hinged to the housing 21. A material guiding plate 24 is fixedly connected inside the housing 21;
[0028] Specifically, after the mortar is placed in the screening barrel 15, the first box door 23 is closed, thereby sealing the open end of the screening barrel 15 and preventing mortar from scattering during screening. The mortar that falls out of the holes of the screening barrel 15 flows along the material guiding plate 24 into the feeding port provided at the bottom of the housing 21, thereby improving the mortar collection efficiency.
[0029] Embodiment 3
[0030] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the second screening mechanism 3 includes a second screening box 31. The second screening box 31 is fixedly connected to the bottom of the housing 21. A second drive motor 32 is fixedly connected to one side of the second screening box 31.

[0031] Specifically, the mortar after the initial screening falls into the second sub-screening box 31, and then the second drive motor 32 is started to drive the threaded rod 33 to rotate, thereby driving the threaded adjustment block 34 and the anti-blocking brush 35 to move, and the threaded adjustment block 34 pushes the mortar back and forth, and the anti-blocking brush 35 cleans the sub-screen 36 to avoid blockage of the sub-screen 36, ensuring the flow of the mortar, thereby performing a secondary screening of the mortar, and the screened mortar will enter the third sub-screening box 37, thereby improving the screening quality.
[0032] The working principle of the mortar screening device is described in detail below.
[0033] like Figures 1-4 As shown, after the mortar is put into the screening barrel 15, the first box door 23 is closed, the first driving motor 11 is started, the first gear 12 is driven to rotate, thereby driving the second gear 13 and the limit rod 14 to rotate, and the screening barrel 15 rotates accordingly, driving the mortar in the screening barrel 15 to shake, so that the mortar with smaller particles flows out of the holes in the screening barrel 15, and the electric rotating rod 16 is started to drive the stirring plate 17 to rotate synchronously, further stirring the mortar, increasing the number of times the mortar is turned over, and the mortar that has been initially screened falls into the second screening barrel along the guide plate 24. In the binary screen box 31, the second drive motor 32 is then started to drive the threaded rod 33 to rotate, thereby driving the threaded adjustment block 34 and the anti-blocking brush 35 to move. The threaded adjustment block 34 pushes the mortar back and forth, and the anti-blocking brush 35 cleans the sub-screen 36 to avoid blockage of the sub-screen 36, ensuring the flow of the mortar, thereby performing a secondary screening of the mortar.
