Technical Field

[0001] This utility model relates to the field of screening technology, specifically to a screening device for mortar production. Background Technology

[0002] Mortar is a bonding material used in bricklaying. It is made by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion.

Detailed Implementation

[0043] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0044] like Figures 1-4 As shown in the figure, this embodiment proposes a screening equipment for mortar production, including: a screening box 1, a screen plate 2, a feeding box 3, a dust prevention mechanism, a screening mechanism, and a feeding mechanism. A support frame 21 is fixedly connected to the bottom end of the screening box 1. The bottom end of the screening box 1 has a feeding port and two discharge ports. The screen plate 2 is fixedly connected inside the screening box 1. The feeding box 3 is fixedly connected to the feeding port. Guide boxes 20 are fixedly connected to both discharge ports. Through the cooperation between the screening box 1, the screen plate 2, the feeding box 3, the dust prevention mechanism, the screening mechanism, and the feeding mechanism, it is easy to seal the screen plate 2, which can effectively prevent dust from flying out. Furthermore, through the swinging of the dust prevention plate 4, the support rod 6 swings on the screen plate 2, thereby moving the cement on the screen plate 2, so that the cement passes through the screen plate 2 for screening. This improves the screening efficiency while reducing cement dust, which is less likely to affect the surrounding environment and reduces cement waste.

[0045] The dustproof mechanism is installed inside the screening box 1 to prevent dust from flying out of the screening box 1. The dustproof mechanism includes a dustproof plate 4, a guard 5, and support rods 6. The dustproof plate 4 is located inside the screening box 1, and the guard 5 is fixedly connected inside the screening box 1. The downward-sloping side of the guard 5 contacts the upward-sloping side of the dustproof plate 4. There are multiple support rods 6. One end of each support rod 6 is fixedly connected to the downward-sloping side of the dustproof plate 4, and the other end of each support rod 6 contacts the screen plate 2. Specifically, the length of the support rod 6 is sufficient to fix one side to the dustproof plate 4 while the other end abuts against the screen plate 2, thereby supporting the other side of the dustproof plate 4 to contact the guard 5. This ensures that the dustproof plate 4 does not hinder its own movement, while forming a seal between the guards 5, thus effectively preventing dust from flying out of the screening box 1.

[0046] The screening mechanism is installed inside the screening box 1 and is used to agitate the cement for screening. The screening mechanism includes: a top plate 7, a connecting rod 8, a fixed plate 9, a rotating plate 10, actuating rods 11, and a drive assembly. A rotating shaft 19 is rotatably connected to the fixed plate 9, and the rotating plate 10 is fixedly connected to the rotating shaft 19. A rotating rod 17 is fixedly connected between the two actuating rods 11, and a rotating ring 18 is rotatably connected to the rotating rod 17. The bottom end of the drive rod 13 is fixedly connected to the rotating ring 18, and the top plate 7 is fixedly connected to the screening box. 1. Two connecting rods 8 are provided, both of which are rotatably connected to the dustproof plate 4. Two fixing plates 9 are provided, both of which are fixedly connected to the top plate 7. A rotating plate 10 is rotatably connected to each of the two fixing plates 9. Two actuating rods 11 are provided, both of which are fixedly connected between the rotating plates 10. The two connecting rods 8 are both located between the two actuating rods 11. A driving assembly is located on the top plate 7 and is used to drive the actuating rods 11 and the rotating plate 10 to swing. The driving assembly includes: The system comprises a drive frame 12, a drive rod 13, and a first motor 14. The drive frame 12 has a rotating hole, and the drive rod 13 is rotatably connected to the rotating hole. The drive frame 12 is rotatably connected to the top plate 7. One end of the drive rod 13 is rotatably connected to the drive frame 12, and the other end of the drive rod 13 is rotatably connected between two actuating rods 11. The first motor 14 is mounted on the top plate 7, and its output end passes through the top plate 7 and is fixedly connected to the drive frame 12. Specifically, the first motor 14 on the top plate 7 drives the drive frame 12 to rotate. When the drive frame 12 rotates, it drives the drive rod 13 to revolve around the drive frame 12. Since the drive rod 13 is inclined on the drive frame 12, the other end of the drive rod 13 will drive the rotating ring 18 to rotate on the rotating rod 17, thereby driving the two actuating rods 11 and the two rotating plates 10 to swing. When the actuating rod 11 swings, it drives the connecting rod 8 and the dustproof plate 4 to reciprocate. At this time, the connecting rod 8 slides adaptively between the two actuating rods 11.

[0047] The feeding mechanism is located inside the feeding box 3 and is used to convey and feed cement. The feeding mechanism includes a guide box 15 and a blower 16. There are two guide boxes 15, and both guide boxes 15 are connected to the feeding box 3. Multiple blowers 16 are installed on both guide boxes 15, and the output ends of the multiple blowers 16 are all facing inwards from the guide box 15. Specifically, when cement is fed, the cement is poured into the feeding box 3, and then the blower 16 in the guide box 15 blows air into the screening box 1, thereby blowing the dust in the feeding box 3 into the screening box 1, thus preventing the dust from flying out of the feeding box 3.

[0048] In this embodiment, during cement screening, the cement to be screened is poured into the feed box 3. Then, the blower 16 inside the guide box 15 blows air into the screening box 1, thereby blowing the dust in the feed box 3 into the screening box 1, thus preventing the dust from flying out of the feed box 3. After that, the cement will enter the screen plate 2. At this time, the first motor 14 is started. The first motor 14 installed on the top plate 7 drives the drive frame 12 to rotate. When the drive frame 12 rotates, it drives the drive rod 13 to revolve around the drive frame 12. Since the drive rod 13 is inclined on the drive frame 12, the other end of the drive rod 13 will drive the rotating ring 18 to rotate on the rotating rod 17. This causes the two actuating rods 11 and the two rotating plates 10 to swing. When the actuating rods 11 swing, they drive the connecting rods 8 and the dustproof plate 4 to run in a cycle. At this time, the connecting rods 8 slide adaptively between the two actuating rods 11. When this action drives the dustproof plate 4 and the support rod 6 to swing, it can not only agitate the cement on the screen plate 2, but also prevent dust from flying out of the screening box 1 through the cooperation between the dustproof plate 4 and the guard 5. The screened cement is discharged through the bottom outlet. Since the screening box 1 and the screen plate 2 are in an inclined state, coupled with the actuation of the support rod 6, the cement or impurities left on the screen plate 2 can be discharged through another outlet.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
