[0030] As Figures 1 to 3 shown, the present utility model discloses a mixing and stirring device 100 for lightweight building materials, including a stirring housing 10 and a hoisting and stirring mechanism 20. The hoisting and stirring mechanism 20 cooperates with the stirring housing 10 to stir the lightweight materials in the stirring housing 10. The hoisting and stirring mechanism 20 can move upward to open the top opening 12 of the stirring housing 10 for adding or scooping out the stirring materials into the stirring housing 10.

[0031] Specifically, a cylindrical stirring bin 11 is sleeved inside the stirring housing 10. The top of the stirring bin 11 has an opening 12, and the hoisting and stirring mechanism 20 can enter or leave the stirring bin 11 from the opening 12. In this application, the side wall of the stirring bin 11 is cylindrical, and the bottom plate of the stirring bin 11 is horizontally arranged.

[0032] The hoisting and stirring mechanism 20 includes a top cover 21, a stirring assembly 22 and a driving assembly 23. The stirring assembly 22 includes a stirring shaft 221 and at least one stirring arm 222.

In the present application, the stirring shaft 221 and the stirring bin 11 are coaxially distributed. Thus, when the driving assembly 23 drives the stirring shaft 221 to rotate, the stirring arm 222 can rotate while abutting against the side wall and the bottom plate of the stirring bin 11. Therefore, while stirring the light material, it is possible to prevent the light material from adhering to the side wall of the stirring bin 11.

[0033] As Figure 4 and Figure 5 shown, further, the stirring arm 222 includes a connecting cross bar 223 and a connecting vertical bar 224.

At least one second scraping plate 226 is provided on the connecting vertical bar 224, and the second scraping plate 226 contacts the side wall of the stirring bin 11. Specifically, the connecting vertical bar 224 is distributed in the vertical direction, the connecting vertical bar 224 is parallel to the stirring shaft 221, and the first scraping plate 225 and the second scraping plate 226 respectively abut against the side wall and the bottom plate of the stirring bin 11. When the stirring arm 222 rotates, the first scraping plate 225 can rotate while abutting against the side wall of the stirring bin 11, and the second scraping plate 226 can rotate while abutting against the bottom plate of the stirring bin 11.

[0034] Further, both the first scraping plate 225 and the second scraping plate 226 are inclined, and the inclination directions of the first scraping plate 225 and the second scraping plate 226 face the rotation direction of the stirring arm 222.

[0035] Further, the positions where the first scraping plate 225 abuts against the side wall of the stirring bin 11 and the position where the second scraping plate 226 abuts against the bottom plate of the stirring bin 11 are made of plastic material, so that the stirring arm 222 is in flexible contact with the side wall and the bottom plate of the stirring bin 11.

[0036] Further, two of the first scrapers 225 are provided on the connecting cross bar 223, and the two first scrapers 225 are distributed along the axial direction of the connecting cross bar 223; two second scrapers 226 are provided on the connecting vertical bar 224, and the two second scrapers 226 are distributed along the axial direction of the connecting vertical bar 224.

Both ends of the second rotating shaft 2262 extend to both sides of the second rotating portion 2241 and are threadedly engaged with second locking screws 2263. Rotating the two second locking screws 2263 can clamp the second connecting portion 2261 through the second rotating portion 2241. Through the above structure, the connecting angle of the first scraper 225 relative to the connecting cross bar 223 can be adjusted, and the connecting angle of the second scraper 226 relative to the connecting vertical bar 224 can be adjusted.

[0038] There are two stirring arms 222, and the two stirring arms 222 are symmetrically distributed relative to the stirring shaft 221.

The output shaft of the drive motor 231 is connected to a first pulley. A second pulley is provided at the top end of the stirring shaft 221. The first pulley and the second pulley are in transmission cooperation through a belt. The drive motor 231 drives the first pulley to rotate, and the first pulley drives the second pulley to rotate through the belt, thereby driving the rotation of the stirring shaft 221.

[0040] Further, the top cover 21 includes a first cover plate 211, a second cover plate 212, a third cover plate 213, and a fourth cover plate 214. Both ends of the support frame 30 are respectively provided with a first rotary connection frame 31 and a second rotary connection frame 32.
