DETAILED DESCRIPTION

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following further details the present utility model with reference to the drawings.

[0019] As Figure 1-4 shown, a sand screening machine for building construction provided by the present utility model includes a support frame 1, a sieve plate 2 and a protective cover 3. Limit columns 4 and support springs 5 are provided near the four corners at the top of the support frame 1. The support springs 5 are sleeved outside the limit columns 4. The top end of the support spring 5 is connected to an inclined bottom plate 6. The inclined bottom plate 6 is in a U-shaped plate structure with the U-shaped opening facing upward. A first support groove 7 and a second support groove 8 are fixedly arranged inside the inclined bottom plate 6. The first support groove 7 is located at the top end, and the second support groove 8 is located at the bottom end. The two side ends of the sieve plate 2 are respectively installed in the first support groove 7 and the second support groove 8. Extension supporting ribs 9 are provided at the bottom of the two opposite outer side walls of the inclined bottom plate 6. Limiting blocks 10 are uniformly extended vertically along the extension supporting ribs 9. Limiting card slots 11 are uniformly opened at the bottom of the opposite side walls of the protective cover 3. The limiting card slots 11 are inserted and adapted to the limiting blocks 10. The protective cover 3 is installed by inserting the limiting blocks 10 on the extension supporting ribs 9 into the limiting card slots 11. The extension supporting ribs 9 support and install the protective cover 3, and at the same time facilitate the disassembly of the protective cover 3 so as to disassemble, clean or replace the sieve plate 2 supported and installed on the first support groove 7 and the second support groove 8, ensuring the stability of the overall assembly while the disassembly and assembly process is convenient.

[0020] As Figure 3 shown, the grooves of the first support groove 7 and the second support groove 8 are adapted to support the sieve plate 2. The height of the second support groove 8 is higher than that of the first support groove 7. The second support groove 8 can block and intercept the impurities screened out by the sieve plate 2.

[0021] As Figure 1-3 shown, an installation seat 12 is provided under the inclined bottom plate 6. A vibration motor 13 is installed inside the installation seat 12. The vibration motor 13 drives the inclined plate to vibrate. The setting of the support springs 5 can increase the vibration, so that the sieve plate 2 can vibrate and screen better to prevent impurities from blocking the sieve plate 2.

[0022] As Figure 1-3As shown, a support column 14 is provided at the top end of the side of the support frame 1, a lower hopper 15 is provided at the top end of the support column 14, a feed port 16 is opened at the top of the protective cover 3, and the feed port 16 is located directly below the lower hopper 15, and the protective cover 3 and the bottom end of the inclined bottom plate 6 form a feed port 17.

[0023] During specific use, the lower hopper 15 transports the sand to the sieve plate 2 covered by the protective cover 3 through the lower material port 17, and then starts the vibration motor 13. The electric motor drives the inclined bottom plate 6 and the sieve plate 2 on the inclined bottom plate 6 to vibrate and screen the sand. The screened sand is transported out from the lower material port 17. After the sand screening is completed, the protective cover 3 is pulled out and disassembled from the extended support rib 9 of the inclined bottom plate 6, and then the sieve plate 2 is removed from the bracket 1 7 and the bracket 2 8 for cleaning or replacement.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto.
