Technical Field

[0001] This utility model belongs to the field of building technology, specifically relating to a sand screening device for building construction. Background Technology

[0002] Architecture is a general term encompassing buildings and structures. The term "building" has both a broad and a narrow meaning. In a broad sense, it refers to all man-made structures, including both houses and structures. In a narrow sense, it refers specifically to houses, excluding structures. A house is a space with a foundation, walls, a roof, doors, and windows, providing shelter from wind and rain, and serving as a place for people to live, work, study, entertain, store goods, or engage in other activities. Unlike buildings, structures lack usable interior space; people generally do not directly engage in production or daily life activities within them. Examples include chimneys, water towers, bridges, dams, and sculptures.

[0003] During construction, a large amount of sand is used. To improve quality, the sand needs to be sieved. However, ordinary sand sieving devices cannot effectively remove impurities such as leaves from the sieve, thus affecting the quality of the finished product. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a sand screening device for construction, which solves the problem of not being able to effectively screen out impurities such as leaves from the sieve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand screening device for construction, comprising a sand screening box, a feeding hopper at the top of the sand screening box, a discharge hopper above one end of the sand screening box, fixing blocks on the inner wall of the sand screening box, a spring installed at the bottom of the fixing blocks, a U-shaped support frame connected to one end of the spring, a sand filter plate slidably connected inside the U-shaped support frame, a conveying cylinder connected to the other end of the sand screening box, the conveying cylinder extending into the interior of the sand screening box, a support block at the top of the conveying cylinder, a second motor on one side of the support block, a first rotating shaft connected to the output end of the second motor, a cam connected to one end of the first rotating shaft, a first motor at one end of the sand screening box, a second rotating shaft connected to the output end of the first motor, a spiral blade mounted on the surface of the second rotating shaft, and connecting inclined plates connected inside the sand screening box, with one end of the connecting inclined plate connected to the conveying cylinder.

[0006] Preferably, the two ends of the hopper are respectively provided with fixing plates, and one end of the fixing plate is respectively provided with bolts, and one end of the bolts passes through the fixing plate and is threadedly connected to the sand screening box.

[0007] Preferably, a lid is provided on the top of the other end of the sand screening box, and a hinge is provided on one side of the lid, and the lid is connected to the sand screening box through the hinge.

[0008] Preferably, a threaded rod is provided above the other end of the sand screening box, and one end of the threaded rod passes through the box cover and is threadedly connected to a handle threaded ring.

[0009] Preferably, the hopper is provided with a feeding plate inside, and a threaded sleeve is provided on one side of the hopper. One end of the threaded sleeve is connected to a handle, and a threaded inner rod is threadedly connected inside the threaded sleeve. One end of the threaded inner rod is connected to a T-shaped slider. A T-shaped groove is provided at the bottom of the feeding plate, and the T-shaped slider slides inside the T-shaped groove.

[0010] Preferably, the top of the feeding plate is provided with a rotating shaft, and the rotating shaft is movably connected to the inner wall of the feeding hopper.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides the following technical solution: a sand screening device for construction, including a sand screening box 1, a feeding hopper 4 at the top of the sand screening box 1, a discharge hopper 5 above one end of the sand screening box 1, fixing blocks 19 respectively provided on the inner wall of the sand screening box 1, a spring 17 installed at the bottom of the fixing blocks 19, a U-shaped support frame 18 connected to one end of the spring 17, a sand filter plate 20 slidably connected inside the U-shaped support frame 18, and a conveying cylinder 10 connected to the other end of the sand screening box 1, with the conveying cylinder 10 extending into the sand screening box 1. Inside the conveying cylinder 10, a support block 11 is provided on the top, a second motor 12 is provided on one side of the support block 11, the output end of the second motor 12 is connected to a first rotating shaft 13, one end of the first rotating shaft 13 is connected to a cam 21, one end of the sand screening box 1 is provided with a first motor 6, the output end of the first motor 6 is connected to a second rotating shaft 28, a spiral blade 29 is installed on the surface of the second rotating shaft 28, and connecting inclined plates 30 are respectively connected inside the sand screening box 1, and one end of the connecting inclined plate 30 is connected to the conveying cylinder 10.

[0024] In this embodiment, by providing a cover 14, a hinge 9, a threaded rod 15, and a handle threaded ring 16, the sand filter plate 20 can be easily pulled out from inside the U-shaped support frame 18, making it convenient to replace and maintain the sand filter plate 20 and increasing the ease of use.

[0025] In this embodiment: by rotating the handle 23, the handle 23 drives the threaded sleeve 24 to rotate, thereby causing the threaded sleeve 24 to move the threaded inner rod 25 and the T-shaped slider 27, so that the T-shaped slider 27 slides inside the T-shaped groove 26, thereby adjusting the feeding plate 22 so that one end of the feeding plate 22 is away from or close to the inner wall of the feeding hopper 4, thereby controlling the falling speed of the sand and avoiding falling too fast, which would affect the screening effect.

[0026] In this embodiment, the fixing plate 3 and bolts 2 are used to install and fix the hopper 4, thereby increasing the convenience and stability of assembly.

[0027] The working principle and usage process of this utility model are as follows: After installation, sand is poured into the hopper 4 and falls onto the surface of the sand filter plate 20 inside the sand screening box 1. Then, the second motor 12 is activated, driving the cam 21 to rotate via the first rotating shaft 13. Through the contact between the cam 21 and the sand filter plate 20, and the spring 17, the cam 21 drives the sand filter plate 20 to move up and down, causing the sand to fall through the sand filter plate 20. Impurities such as leaves are output through the discharge hopper 5, thus separating them and increasing the screening effect. The screened sand falls into the conveying cylinder 10 through the connecting inclined plate 30. Then, the first motor 6 is activated, driving the spiral blade 29 to rotate via the second rotating shaft 28, thus outputting the sand through the spiral blade 29 and increasing the discharge effect. All electrical equipment in this device is powered by an external power source.
