Description

Technical Field

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

[0002] Premixed mortar refers to a mixture made from cement, sand, and necessary admixtures and additives, prepared in a specific ratio through centralized metering and mixing, and then transported and used using specialized equipment. Premixed mortar includes both dry-mixed and wet-mixed mortar. Developing premixed mortar is an important measure for energy conservation and emission reduction, and it is also a significant manifestation of promoting public welfare projects. Before use, premixed mortar needs to be screened to remove large particles and impurities, thereby improving its quality.

[0003] Chinese Patent Publication No. CN221063425U discloses a premixed mortar screening device, including a screening box with support legs installed at the four corners of the bottom. A feed pipe is installed on the screening box, and a storage hopper is installed on the feed pipe. Through the arrangement of the storage hopper, partitions, and motor, when premixed mortar needs to be screened, it is poured into the storage hopper all at once. Then, the motor is started, and its rotation drives the partitions to slide back and forth. When the two first through holes on the partitions coincide with the two second through holes on the limiting plate, the premixed mortar falls out and falls into the arc-shaped filter screen for screening. When the partitions slide to block the two second through holes on the limiting plate, the premixed mortar stops falling, thus allowing sufficient time for screening. This eliminates the need for workers to constantly use tools to pour premixed mortar onto the screen for screening, reducing the workload of workers and providing convenience and speed.

[0004] However, in actual use, the above-mentioned device only uses the arc-shaped filter screen to screen the mortar raw materials. If the raw materials adhere to the arc-shaped filter screen, the rotating arc-shaped filter screen cannot scrape off the adhered raw materials. If the adhered raw materials are not scraped off in time, they will clog the filter screen and even affect the screening efficiency. In addition, the arc-shaped filter screen in the above-mentioned device is located inside the screening box, which makes it difficult to remove the filtered impurities. Utility Model Content

[0022] Working Principle: This utility model discloses a premixed mortar screening device. During use, the mortar to be screened is poured into the screening trough 3. Then, the motor 17 is started. The motor 17 drives the first eccentric wheel 14 and the second eccentric wheel 15 to rotate through the drive rod 16. The first eccentric wheel 14 first touches the first baffle 12 and pushes the first baffle 12. The first baffle 12 drives the first rotating shaft 8 to rotate. The first rotating shaft 8 drives the vertical plate 5 and the screening trough 3 to swing to the left. Then, the first eccentric wheel 14 moves away from the first baffle 12. Under the action of gravity, the screening trough 3 swings to the right to its original state. Then, the second eccentric wheel 15 touches the second baffle 13 and pushes the second baffle 13. The second baffle 13 drives the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the connecting plate 9 and the disturbance rake 11 to swing to the right. Then, the second eccentric wheel 15 moves away from the second baffle 13. Under the action of gravity, the disturbance rake 11 swings to the left to its original state.

[0023] The oscillating trough 3 can sieve the mortar, and the oscillating rake 11 can scrape off the adhering mortar. The qualified mortar passes through the sluice hole 4 and is collected inside the collection trough 2, while the unqualified mortar remains inside the sieve trough 3. The open sieve trough 3 makes it easy to remove internal impurities and is easy to clean.

[0024] When the motor 17 is working, it can drive the screening trough 3 to swing and the agitator 11 to swing, achieving two goals at once. Furthermore, the screening trough 3 and the agitator 11 swing in opposite directions. The swinging of the screening trough 3 can screen the mortar, while the swinging of the agitator 11 can scrape off the adhering mortar, preventing the adhering mortar from clogging the sluice hole 4, thereby improving the screening efficiency.
