Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a screen for building construction. Background Art

[0002] Concrete mortar is needed in construction. Concrete mortar is a mixture of cement, sand, gravel and other additives. When processing sand and gravel, a screen is needed to block large particles of sand and gravel to improve the mixing effect of concrete.

[0003] The existing screen will tilt at a certain angle when in use, and then the staff will use a shovel to throw sand and gravel on the screen. In actual operation, it is inevitable that there will be large sand and gravel blocking the screen, resulting in reduced screening efficiency. The existing cleaning of the screen is to vibrate and clean it without changing the angle of the screen. For example, the application number is CN202223431603.6, a kind of construction screen. The above utility model patent is provided with a support frame 1, a drive motor 1, a support frame 2, a rotating rod and a cam.

[0028] See also Figure 3 Better yet, the cam 7 of the utility model matches the movement trajectory of the screen 2 on the arc groove 12, and when the screen 2 moves to the end of the arc groove 12, the cam 7 is squeezed with the screen 2, and when the screen 2 rotates, the cam 7 can realize vibration cleaning of the screen 2, thereby achieving the effect of cleaning the screen 2 while rotating.

[0029] See also Figure 1 Finally, a collecting box 14 is provided between the supporting bottom plates 1 of the utility model, and the collecting box 14 is convenient for collecting the required sand and gravel after screening, which is convenient for subsequent use.

[0030] The working principle of this utility model:

[0031] First, the staff places the screen at the required position, and then adjusts the screen 2 to the initial state (such as Figure 1As shown in the figure), you can throw sand and gravel onto the screen 2 with a shovel to screen the sand and gravel. Qualified sand and gravel will pass through the screen 2 and enter the collection box 14, completing the collection of qualified sand and gravel. When the screening is completed, there will be larger sand and gravel stuck on the screen 2. If it is not cleaned up, it will lead to a decrease in the subsequent screening efficiency. At this time, the staff can withdraw the collection box 14 and then turn on the drive motor 4. The drive motor 4 drives the active shaft 5 to rotate. The active shaft 5 drives the driven shaft 6 to rotate through the synchronous belt 8. The rotation of the active shaft 5 drives the screen 2 to rotate. At the same time, the fixed shaft 10 also facilitates the rotation of the screen 2. The rotation of the driven shaft 6 drives the cam 7 to rotate, so that the screen 2 and the cam 7 rotate synchronously. When the screen 2 rotates to be perpendicular to the ground, the part The sand and gravel stuck on the screen 2 will fall down under the action of its own gravity. As the screen 2 continues to rotate, the rotation trajectory of the cam 7 will contact the surface of the screen 2. Since the screen 2 can move to a certain amplitude, as the screen 2 rotates, the side of the screen 2 with the sand and gravel stuck on it will correspond to the ground. Under the two effects of the vibration of the cam 7 on the screen 2 and the gravity of the sand and gravel themselves, the sand and gravel stuck on the screen 2 will fall from the screen 2 and fall to the ground, thereby improving the cleaning effect. When the screen 2 moves to the end of the arc groove 12 through the slider 13 (such as Figure 2 As shown), if the screen 2 needs to be continued to be used, the drive motor 4 can be reversed to drive the screen 2 to reset. When the screen 2 is reset, the cam 7 can still vibrate and clean the screen 2, which significantly improves the cleaning effect.

[0032] In summary, the utility model provides a screen for construction, comprising: a supporting base plate, two groups of fixed plates are symmetrically arranged on the supporting base plate, a screen is movably arranged between the fixed plates, and a rotating assembly and a cleaning assembly are arranged between the fixed plate and the screen; the rotating assembly comprises a driving motor arranged on a side of a group of the fixed plates away from the screen and a driving shaft arranged at the output end of the driving motor and passing through the interior of the fixed plates; the cleaning assembly comprises a driven shaft arranged on a side of a group of the fixed plates away from the screen and passing through the interior of the fixed plates and a cam arranged at the end of the driven shaft, the screen is driven to rotate by the rotating assembly, and the sand and gravel stuck on the screen are cleaned by the cleaning assembly, thereby improving the screening efficiency. In summary, the utility model drives the screen and the cam to rotate through the rotating component, and during the rotation of the screen, the cam will contact and squeeze the screen, that is, when the screen rotates, the cam will also vibrate and clean the screen, and when the cam can contact the screen, the angle of the screen has changed, so that the sand and gravel stuck on the screen tend to move downward under the action of its gravity, so that the sand and gravel after vibration will not fall onto the screen again, thereby improving the cleaning efficiency.
