[0056] To gain a clearer understanding of the technical features, objectives, and effects of this utility model, the following comparison is made.

[0057] The accompanying drawings illustrate specific embodiments of this utility model.

[0058] Example 1: A preferred embodiment of the sand screening device for building mortar provided by this utility model is as follows:

[0059] Figure 1 to Figure 4 As shown: A sand screening device for building mortar, comprising:

[0060] Framework 1;

[0061] Among them, the right side of frame 1 has a notch 8;

[0062] Support legs 2 are fixedly installed at the bottom of the four corners of frame 1. The support legs 2 can be used to make the entire device...

[0063] For stable support, a feed plate 3 is installed below the frame 1 and is fixedly installed with the support leg 2.

[0064] Material plate 3 facilitates sand screening during material feeding;

[0065] Filter component 5, connect it to frame 1;

[0066] The flipping component 6 is installed between the frame 1 and the filtering component 5.

[0067] Filtering component 5 includes:

[0068] Motor 51 is located at the lower right position of frame 1;

[0069] The lower end of the short rod 54 is fixedly installed to the output end of the motor 51, and the upper end of the short rod 54 is connected by a pin.

[0070] A connecting rod 52 is movably connected, and a concave block 53 is movably connected to the end of the connecting rod 52 away from the short rod 54;

[0071] The screen frame 55 is positioned above the frame 1 and is fixedly installed with the concave block 53.

[0072] L-shaped block 56, one end of which is fixedly installed to the bottom surface of screen frame 55, and the other end of L-shaped block 56 is fixed to the inner surface of frame 1.

[0073] The wall has a sliding groove.

[0074] In the specific implementation process, motor 51 is started, and the output shaft of motor 51 drives the short rod connected to it.

[0075] 54 rotates in a circle, and the rotation of short rod 54 in turn gives connecting rod 52 a tendency to move, due to L-shaped block 56.

[0076] With this configuration, the connecting rod 52 can stably and effectively drive the screen frame 55 to reciprocate during operation.

[0077] This allows for efficient screening.

[0078] In this embodiment, an L-shaped mounting base 4 is fixedly installed on the lower surface of the motor 51.

[0079] The motor 51 is fixedly installed with the frame 1, and the L-shaped mounting bracket 4 allows for secure installation, facilitating easy mounting.

[0080] Motor 51 is operating normally.

[0081] Example 2: Based on the above implementation scheme, the tilting component 6 includes:

[0082] The rack 61 is fixedly installed on the top surface of the screen frame 55;

[0083] Gear 62 is configured to mesh with rack 61;

[0085] One side of the support plate 64 is rotatably mounted, and the support plate 64 is fixedly installed on the top surface of the frame 1;

[0086] Lever 65 is fixedly installed on the outer wall of the rotating shaft 63. There are multiple levers 65.

[0087] The levers 65 are evenly spaced on the outer wall of the rotating shaft 63. The sand can be pushed aside by the installed levers 65.

[0088] Avoid piling up, as this will affect the screening effect.

[0089] In the actual implementation process, when the screen frame 55 moves, it will drive the associated rack 61 to move synchronously.

[0090] The movement of rack 61 drives gear 62 to rotate, and the rotation of gear 62 drives the connected components...

[0091] The rotating shaft 63 rotates together, which in turn causes the lever 65 fixed on the rotating shaft 63 to rotate, thus affecting the screening process.

[0092] During the process, lever 6 continuously agitates the sand on the screen surface, effectively preventing sand accumulation and ensuring high efficiency in screening.

[0093] To ensure efficient and stable operation and avoid reduced screening efficiency due to sand accumulation.

[0094] In this embodiment, a feed hopper 7 is provided above the lever 65, and the feed hopper 7 is fixedly installed on the support.

[0095] The top surface of the support plate 64 is equipped with a feed hopper 7 for easy material feeding.

[0096] Working principle: First, the sand to be screened is fed onto the screen frame 55 through the feed hopper 7. Then,

[0097] When motor 51 is started, its output shaft drives the connected short rod 54 to rotate in a circular motion.

[0098] The rotation of rod 54 transmits power, causing connecting rod 52 to tend to move. This is facilitated by the L-shaped block 56.

[0099] The connecting rod 52 can stably and efficiently drive the screen frame 55 to reciprocate during movement, thereby achieving high efficiency.

[0100] Effective screening process.

[0101] As the screen frame 55 moves, the rack 61 in contact with it will be affected, producing the same...

[0102] Motion trend. The movement of rack 61 drives gear 62 to rotate, which in turn causes the shaft coaxial with gear 62 to rotate.

[0103] 63 rotates synchronously, and the rotation of shaft 63 drives lever 65 to rotate accordingly. In this way, throughout the entire screening process...

[0104] During the process, lever 65 can turn the sand over, effectively preventing it from piling up and ensuring the smooth operation of the screening process.

[0105] The process proceeded smoothly, and the final screened sand was discharged through feed plate 3.

[0106] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model.

[0107] The scope of this invention is as follows. Any person skilled in the art, without departing from the concept and principles of this invention, may apply this invention.
