[0001] The utility model relates to the technical field of sand screening for construction, in particular to sand screening equipment for construction. Background Art
[0002] Sand refers to tiny stones. Sand has a wide range of uses: in addition to being used in construction, road construction, filtration, aquaculture and beautification, and as a smelting agent, it is also the main material for making glass. It contains silicon elements, and in sports, in addition to sand pools, it can also be used as sandbags for boxing and flood prevention. In daily life, it plays a role in cleaning, such as sand for factory workers to wash their hands and feet, and for cleaning wine bottles, porcelain, metal tableware, etc.
[0003] However, the existing construction sand screening equipment still has the following shortcomings: In the prior art, the traditional screening equipment has low screening accuracy and cannot effectively remove impurities and foreign matter in the sand. It usually adopts a single screening method with low screening efficiency and cannot meet the requirements of construction for sand quality and quantity, thus affecting the quality of construction. Therefore, we propose a sand screening equipment for construction. Utility Model Content

[0023] See also Figure 1-4 , the utility model provides a technical solution:
[0024] A sand screening device for construction includes a bottom plate 1, pulleys 2 are fixedly connected at the four corners of the lower end of the bottom plate 1, a fixed plate 3 is fixedly connected to the left part of the upper end of the bottom plate 1, a side plate 4 is fixedly connected to the right end of the bottom plate 1, a rotating motor 5 is fixedly connected to the lower right end of the side plate 4, an output end of the rotating motor 5 is fixedly connected to a driving gear 6, a movable column 7 is fixedly connected to the left end of the driving gear 6, a plurality of beating rods 8 are fixedly connected to the outer surface of the movable column 7, a connecting column 9 is movably connected to the upper left end of the side plate 4 through a bearing, and the connecting column 9 The left end of the driven gear 10 is fixedly connected to the left end of the driven gear 10, and the first drum screening machine 11 is fixedly connected to the left end. The inner wall of the first drum screening machine 11 is provided with four slide grooves 12. The second drum screening machine 13 is clamped in the first drum screening machine 11, and the outer surface of the second drum screening machine 13 is fixedly connected with four convex strips 14. A fixed cover 15 is clamped on the left part of the outer surface of the first drum screening machine 11, and a feed trough 16 is inserted and fixedly connected to the upper end of the fixed cover 15, and a movable plate 17 is clamped on the upper end of the feed trough 16.
[0025] In this embodiment, the left end of the movable column 7 is movably connected to the right end of the fixed plate 3 through a bearing. The bearing can provide better support and positioning to ensure the rotation accuracy of the movable column 7, thereby improving the beating effect and stability of the beating rod 8; a plurality of beating rods 8 are distributed at equal distances in pairs, and the uniform distribution of the beating rods 8 can ensure that during the rotation process, each beating rod 8 can beat the sand with the same frequency and strength, thereby achieving a uniform screening effect; the output end of the rotating motor 5 is interspersed with the right end of the side plate 4 and extends to the left end of the side plate 4. The design of the output end interspersed with the side plate 4 can increase the stability of the rotating motor 5, reduce shaking and noise during operation, and also prevent the rotating motor 5 from being displaced during operation; the driving gear 6 is meshed and connected with the driven gear 10. When the driving gear 6 rotates, it is meshed with the driven gear 10. The meshing of the moving gear 10 transmits power to the driven gear 10, thereby driving the first drum screen 11 and the second drum screen 13 to rotate, thereby screening the sand; the four chutes 12 are adapted to the four convex strips 14, and the second drum screen 13 is clamped in the first drum screen 11 through the four convex strips 14.

In addition, this clamping method makes the installation and disassembly of the second drum screen 13 more convenient. It is only necessary to align the convex strip 14 with the chutes 12, and then push or pull it out to complete the installation or disassembly, thereby reducing the maintenance time and cost of the equipment.
[0026] It should be noted that the utility model is a sand screening device for construction. In the specific use process, the sand to be screened is placed in the feed trough 16 by opening the movable plate 17, and the sand falls into the first drum screening machine 11 under the action of gravity. Then the movable plate 17 is closed, and the rotating motor 5 is started. The output end of the rotating motor 5 drives the driving gear 6 to rotate, and the driving gear 6 is meshed and connected with the driven gear 10. The driven gear 10 rotates accordingly, thereby driving the first drum screening machine 11 and the second drum screening machine 13 to rotate together. The sand in the first drum screening machine 1 During the rotation of the first and second drum screening machines 11 and 13, screening is performed through the screen, smaller particles fall from the screen, and larger particles remain on the surface of the screen. The beating rod 8 on the movable column 7 continuously beats the screen during the rotation process to prevent sand from clogging the screen and improve the screening efficiency. The screened sand is discharged from the discharge ports (not shown in the drawings) of the first and second drum screening machines 11 and 13 respectively. When it is necessary to clean or replace the screen, the fixed cover 15 is opened and the second drum screening machine 13 is taken out of the first drum screening machine 11 for cleaning or replacement.
