Description

Technical Field

[0001] This utility model relates to the field of dry-mixed mortar processing technology, and in particular to a screening device for dry-mixed mortar processing with good screening effect. Background Technology

[0002] Dry-mixed mortar is a precast concrete product made of cement, sand and other filler materials. It can be mixed with water before use, reducing the space occupied by material storage on the construction site, facilitating construction site management and reducing construction safety hazards.

[0003] In the existing technology, in order to maintain a stable dispersion effect in the use of dry-mixed mortar, the mortar needs to be screened. During screening, the vibration of the screen will cause sand and soil to splash, polluting the processing environment. At the same time, wear will affect the service life of the screening device and increase the processing cost. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where the vibration of the screen during screening causes sand and soil to splash and pollute the processing environment, while also causing wear and tear that affects the service life of the screening device and increases processing costs. Therefore, this invention proposes a screening device for dry-mixed mortar processing with good screening effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for dry-mixed mortar processing with good screening effect includes a frame, a motor fixedly connected to the inner wall of the frame, a screening frame provided inside the frame, the output shaft of the motor fixedly connected to the end of the screening frame, multiple openings inside the screening frame, a connecting frame inserted into the inner wall of the screening frame at one of the openings, a screening screen fixedly connected inside the connecting frame, a hanging block fixedly connected to the inner wall of the top of the frame, a fixing rod fixedly connected to the inner wall of the bottom of the hanging block, the bottom wall of the fixing rod rotatably connected to the inner wall of the screening frame, a connecting rod fixedly connected to the wall of the fixing rod, and a scraper fixedly connected to the end of the connecting rod away from the fixing rod, the scraper being slidably disposed on the side wall of the screening screen.

[0020] 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.

[0021] Reference Figure 1-3 A screening device for dry-mixed mortar processing with good screening effect includes a frame 1, a motor 2 fixedly connected to the inner wall of the frame 1, a screening frame 3 provided inside the frame 1, the output shaft of the motor 2 fixedly connected to the end of the screening frame 3, multiple openings inside the screening frame 3, a connecting frame 4 inserted into the inner wall of the screening frame 3 at the opening, a screening screen 5 fixedly connected inside the connecting frame 4, a hanging block 7 fixedly connected to the inner wall of the top of the frame 1, a fixing rod 8 fixedly connected to the inner wall of the bottom end of the hanging block 7, the bottom end of the fixing rod 8 rotatably connected to the inner wall of the screening frame 3, a connecting rod 9 fixedly connected to the rod wall of the fixing rod 8, a scraper 10 fixedly connected to the end of the connecting rod 9 away from the fixing rod 8, and the scraper 10 slidably disposed on the side wall of the screening screen 5.

[0022] The connecting frame 4 is set to be arc-shaped to match the screening frame 3. An anti-overflow ring 6 is fixedly connected to the inner wall of the top of the screening frame 3. The bottom of the anti-overflow ring 6 is set to be arc-shaped. A cavity is opened in the inner wall of the connecting frame 4. A spring 11 is fixedly connected to the inner wall of the cavity. A slider 12 is fixedly connected to the end of the spring 11. The slider 12 is slidably set in the inner wall of the cavity. An insert block 13 is fixedly connected to the end of the slider 12 away from the spring 11. Multiple slots are opened in the inner wall of the screening frame 3. The insert block 13 is inserted into the inner wall of the slot.

[0023] In use, the mortar to be screened is placed into the inside of the screening frame 3. The output shaft of the motor 2 rotates, which drives the screening frame 3 to rotate. This allows the mortar to be filtered and screened out along the screening mesh 5, ensuring the screening effect while reducing the wear caused by long-term vibration of the shaking structure. It also reduces the noise during screening. The inclined setting of the screening frame 3 can improve the screening efficiency when the screening frame 3 rotates. The anti-overflow ring 6 can prevent the mortar from overflowing to the outside of the screening frame 3. The hanging block 7 and the fixing rod 8 are fixedly set and can be scraped along the inner wall of the rotating screening frame 3 through the connecting rod 9 and the scraper 10, which can improve the screening efficiency and prevent the mortar from piling up, ensuring the screening efficiency. The spring 11 can push the slider 12 to move, so that the insert block 13 extends into the inside of the slot, which can improve the stability of the connecting frame 4 connected to the inside of the screening frame 3.

[0024] To facilitate the removal of connecting frame 4, such as Figure 1-3 As shown, the connecting frame 4 has a strip-shaped opening on the inner wall of the cavity. A lever 14 is slidably provided on the inner wall of the strip-shaped opening. The end of the lever 14 extends into the cavity and is fixedly connected to the slider 12. The end of the lever 14 away from the slider 12 extends to the outside of the connecting frame 4 and is fixedly connected to an arc-shaped pull plate 15. The end of the insert block 13 has a rounded corner. The screening frame 3 is located on the inner wall of the slot and matches the insert block 13.

[0025] Pulling the arc-shaped lever 15 and the lever 14 facilitates the adjustment of the slider 12, causing the insert 13 to retract into the cavity, which facilitates the disassembly of the connecting frame 4 and makes maintenance and replacement easier. The end of the insert 13 is rounded to reduce wear during connection.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
