Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a sieve for construction. Background Technology

[0002] Some sieves suffer from low screening efficiency, relying solely on manual or simple mechanical operation, which cannot quickly process large quantities of materials, thus hindering construction progress. Moreover, their screening accuracy is poor, making it difficult to accurately separate materials of different particle sizes. The inclusion of substandard materials can affect the stability and durability of building structures. In addition, the unreasonable structural design of traditional sieves makes them prone to shaking and jamming during operation, which not only affects the screening effect but also shortens the equipment's lifespan and increases maintenance costs. Furthermore, maintenance and cleaning are cumbersome, and cleaning clogged screens is difficult, time-consuming, and labor-intensive. In view of these problems, it is urgent to develop a new type of construction sieve that is efficient, accurate, stable, and easy to maintain to meet the growing construction needs of the modern construction industry.

[0031] Reference Figure 1-4 This utility model discloses a construction sieve, which includes a shell 1, a fixed frame 5 placed at the upper end of the shell 1, bolts 7 slidably connected to the inner wall of the fixed frame 5, a first sliding groove 13 provided on the upper surface of the rear end of the shell 1, a first slider 4 fixedly connected to the lower end of the fixed frame 5, a second sliding groove 23 provided on the upper surface of the front end of the shell 1, the inner wall of the second sliding groove 23 slidably connected to the first slider 4, a first slot 8 fixedly connected to the inner wall of the shell 1, a second slot 10 fixedly connected to the inner wall of the shell 1 near the bottom, a tray 11 slidably connected to the inner wall of the second slot 10, a second sieve 9 slidably connected to the inner wall of the first slot 8, a first sieve 6 fixedly connected to the inner wall of the fixed frame 5, a vibration motor 12 fixedly connected to the lower end of the second sieve 9, and a reciprocating screening mechanism provided at the rear end of the shell 1.

[0032] The reciprocating screening mechanism includes a fixed frame 2, a cam 3, a connector 14, a sliding rod 15, a spring 16, a drive motor 17, a first bracket 18, a slide rail 19, a second slider 20, a second bracket 21, and a roller 22. The front end of the outer shell 1 is fixedly connected to the fixed frame 2. The inner wall of the top of the fixed frame 2 is fixedly connected to the first bracket 18. The upper end of the first bracket 18 is fixedly connected to the drive motor 17. The output end of the drive motor 17 is fixedly connected to the cam 3. The outer surface of the cam 3 is in rolling contact with the roller 22. The outer side of the roller 22 is in rotatable contact with the second bracket 21. Next, the rear end of the second bracket 21 is fixedly connected to the sliding rod 15, the spring 16 is located outside the sliding rod 15, and the two ends of the spring 16 are in close contact with the first bracket 18 and the second bracket 21 respectively. The outer surface of the sliding rod 15 is slidably connected to the first bracket 18. The rear end of the first bracket 18 is fixedly connected to the connector 14. The inner wall of the connector 14 is threadedly connected to the bolt 7. The upper end of the second bracket 21 is fixedly connected to the second slider 20. The outer surface of the second slider 20 is slidably connected to the slide rail 19. The upper surface of the slide rail 19 is fixedly connected to the first bracket 18.

[0033] Working principle: When the drive motor 17 starts, its output end drives the cam 3 to rotate. Since the outer surface of the cam 3 is in rolling connection with the roller 22, and the roller 22 is connected to the sliding rod 15 through the second bracket 21, and the spring 16 is sleeved on the outside of the sliding rod 15 with its two ends in close contact with the first bracket 18 and the second bracket 21 respectively, when the cam 3 rotates, it will push the roller 22 and the connected second bracket 21 and sliding rod 15 to reciprocate. The second slider 20 at the upper end of the second bracket 21 slides on the slide rail 19, which plays a guiding and stabilizing role, ensuring the smooth progress of the reciprocating motion.

[0034] The sliding rod 15 is connected to the bolt 7 via the connector 14. The bolt 7 is slidably connected to the inner wall of the fixed frame 5. When the sliding rod 15 reciprocates, it drives the bolt 7 through the connector 14, thereby causing the fixed frame 5 to reciprocate on the first slide groove 13 and the second slide groove 23 of the outer shell 1. The first slider 4 at the lower end of the fixed frame 5 slides in the slide groove to ensure the stability of the movement of the fixed frame 5. The first sieve 6 inside the fixed frame 5 reciprocates accordingly to screen the building materials placed on it. At the same time, the vibration motor 12 at the lower end of the second sieve 9 is started, causing the second sieve 9 to vibrate, further improving the screening effect.

[0035] The materials after being screened by the first sieve 6 and the second sieve 9 fall into different positions according to their particle size. The smaller particles fall into the tray 11 below through the second sieve 9, while the larger particles remain on the first sieve 6 or the second sieve 9. The tray 11 can be cleaned periodically. The tray 11 is slidably connected to the inner wall of the outer casing 1 through the second slot 10, making it easy to remove and replace in order to collect the screened materials.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
