Description

A stone powder screening device for weather-resistant stone paint Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a stone powder screening device for weather-resistant stone paint. Background Technology

[0002] According to a search, Chinese patent document, publication number CN203494758U, discloses a stone powder screening device for real stone paint. This device uses a vibrating screen to drive the raw material through a sieve for screening. The addition of a roller improves the screening efficiency of the vibrating screen, and the stone powder is less likely to clog the sieve mesh, making it highly practical. However, while the roller provides some anti-clogging effect, it lacks a cleaning function. Long-term use can easily lead to clogging of the sieve mesh, and stone powder can accumulate, hindering discharge and affecting the screening effect. Furthermore, although screening can be performed using a vibrating screen, the screening efficiency is poor, often resulting in incomplete screening and discharge, requiring repeated screening, leading to cumbersome procedures and reduced processing efficiency.

It features thorough stone powder screening, reduces repeated screening processes and improves processing efficiency, and also has a cleaning function to prevent sieve blockage and stone powder accumulation inside the device, thus solving the aforementioned technical problems.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stone powder screening device for weather-resistant stone paint, comprising a base and a fixed cylinder. A sieve cylinder is movably mounted on the inner side of the fixed cylinder via a bearing. A threaded rod is movably mounted on the lower end of the inner side of the fixed cylinder via a bearing. A scraper is threadedly connected to the outer side of the threaded rod. A baffle is provided on the left side of the fixed cylinder. An electric push rod is fixedly installed between the baffle and the fixed cylinder. A connecting seat is fixedly installed on the outer side of the fixed cylinder. A lifting cylinder is provided between the connecting seat and the base.

[0007] Preferably, a movable hole is provided at the center of the bottom side of the base, and a groove is provided on the left side of the base, with a guide plate fixedly installed on the inner side of the groove.

[0008] The above technical solution facilitates the movement of the telescopic hose through the movable hole, thus avoiding the impact on use when the fixed cylinder is tilted. Moreover, the guide plate facilitates the discharge of larger stones after screening.

[0009] Preferably, a partition is fixedly installed on the left end of the inner side of the fixed cylinder, and a screen cylinder is movably installed on the inner side of the partition via a bearing. A discharge seat is fixedly installed at the middle position of the bottom side of the fixed cylinder, and a telescopic hose is provided on the bottom side of the discharge seat. The telescopic hose is located inside the movable hole, and a discharge hole is opened at the left end of the bottom side of the fixed cylinder.

[0010] With the above technical solution, after complete screening, the stone powder is discharged and collected by the telescopic hose after passing through the discharge seat, while larger stones are discharged through the discharge hole and then guided and collected by the guide plate. The telescopic hose facilitates telescopic discharge.

[0011] Preferably, the outer side of the screen cylinder has a plurality of equidistantly arranged screen holes, and the inner side of the screen holes is provided with a screen mesh, and a drive motor is fixedly installed on the right side of the screen cylinder.

After feeding is completed, the drive motor is started to drive the screen cylinder to rotate, thereby facilitating the rotation and screening of the raw material. At the same time, the two sets of lifting cylinders on the left and right ends move up and down in opposite directions, which helps to continuously create an inclination during the screening process, making it easier for the raw material to move inside the screen cylinder, improving the screening effect and efficiency, and ensuring thorough screening without the need for multiple screenings.

[0019] 2. After screening, the two sets of lifting cylinders on the right end are activated to move the left end of the fixed cylinder upward, creating an inclination. Then, the electric push rod is activated to move the baffle away from the screen cylinder. At this time, the screen cylinder continues to rotate, thereby discharging the screened stone material to the inner side of the leftmost fixed cylinder. After being discharged through the discharge hole, it is discharged and collected by the guide plate. Then, the cleaning motor is activated to rotate forward and backward, which facilitates the relative movement of the two sets of scrapers to clean the inner wall of the fixed cylinder. At the same time, the stone powder is pushed to the discharge seat and discharged and collected by the telescopic hose. The brush can clean the screen holes on the screen cylinder by discharging the stone powder, avoiding clogging. Attached Figure Description

A screen cylinder 3 is movably installed on the inner side of the partition plate 201 via a bearing. A discharge seat 202 is fixedly installed in the middle of the bottom side of the fixed cylinder 2. A telescopic hose 2021 is provided on the bottom side of the discharge seat 202. The telescopic hose 2021 is located inside the movable hole 101, and a discharge hole 203 is opened at the left end of the bottom side of the fixed cylinder 2.

After being discharged through the discharge hole 203, it is discharged and collected by the guide plate 1021. Then, the cleaning motor 401 is activated to rotate forward and backward, which facilitates the relative movement of the two sets of scrapers 5 to clean the inner wall of the fixed cylinder 2.
