[0037] See also Figure 1-7 On the basis of the first embodiment, the scraping mechanism 3 further comprises a second motor 303, the second motor 303 is fixedly connected to the center of the top of the barrel cover 2, the second motor 303 is fixedly connected to a stirring rod 32 at the bottom, the stirring rod 32 surface is densely fixedly connected to stirring blades 31, the front and rear sides of the top of the barrel cover 2 are fixedly connected to support plates 39, a top seat 33 is fixedly connected between the front and rear support plates 39, the left and right sides of the top of the barrel cover 2 are fixedly connected to slide bars 38, the top of the slide bar 38 and the bottom of the top seat 33 are fixedly connected, and the left and right slide bars 38 A top plate 37 is slidably connected to the surface, and a first motor 36 is fixedly connected to the left and right sides of the bottom of the top plate 37. A threaded rod 35 is fixedly connected to the bottom of the first motor 36. A scraper 302 is rotatably connected to the bottom of the threaded rod 35. The scraper 302 is arranged at the bottom of the barrel cover 2. Threaded holes 34 are provided inside the left and right sides of the barrel cover 2. The surface of the threaded rod 35 and the inside of the threaded rod 35 are threadedly connected. The barrel cover 2 and the barrel body 4 are both threadedly connected with a first bolt 301. There are two threaded rods 35, and the thread lines on the surfaces of the two threaded rods 35 have the same specifications and the same direction.

[0038] Furthermore, the first bolt 301 threadably fixes the two, the second motor 303 drives the stirring rod 32 to rotate, and the stirring rod 32 drives the stirring blades 31 to stir the chemical raw materials in the barrel body 4, thereby avoiding a potential danger when the chemical raw materials are manually stirred, reducing the human inhalation of gases generated by the stirring of chemical raw materials, and improving the working safety environment of operators. The threaded rod 35 and the threaded hole 34 are threadedly connected, and the threaded rod 35 can be lifted and moved.

[0039] In actual operation, when this device is used, when the chemical raw materials are safely produced, it is necessary to ensure the uniformity of the chemical raw materials during stirring. First, the barrel 4 is placed on the round table 6, and when the third motor 516 is started, the third motor 516 drives the rotating rod 517 to rotate, and the rotating rod 517 drives the gear 512 to rotate. Since the gear 512 and the arc-shaped gear ring 5103 are meshed and connected, the gear 512 can rotate around the arc-shaped gear ring 5103. When the gear 512 rotates, the connecting plate 513 can drive the annular slider 515 in the arc-shaped slide groove 511 At the same time, since the long block 5104, the hinge rod 518 and the connecting seat 519 are hinged, when the long block 5104 is driven to move by the rotating rod 517, the T-plate 5101 can also be driven to slide in the first T-slot 514, until the T-plate 5101 drives the clamping ring 5102 to clamp and fix the barrel body 4. At this time, the barrel body 4 can be clamped and fixed on the round table 6, which is convenient for the fourth motor 62 to start and drive the rotating shaft 61 to rotate. When the rotating shaft 61 drives the round table 6 to rotate, the barrel body 4 can also rotate, which is convenient for a uniform mixing of chemical raw materials;

At this time, the position of the rotating rod 517 can be limited and fixed, and the position of the clamping ring 5102 can be limited and fixed, so that the clamping ring 5102 can firmly clamp and fix the barrel body 4;

[0041] After the chemical raw materials are poured into the barrel body 4, the barrel cover 2 is placed on the barrel body 4, and the two are screwed together by the first bolt 301. When the second motor 303 is started, the second motor 303 drives the stirring rod 32 to rotate, and the stirring rod 32 drives the stirring blade 31 to stir the chemical raw materials in the barrel body 4, thereby avoiding a potential danger when the chemical raw materials are stirred manually and reducing the inhalation of the gas generated by the stirring of the chemical raw materials.

[0042] When the inner wall of the barrel body 4 needs to be cleaned in the later stage, and the chemical raw material residues adhered to the inner wall of the barrel body 4 need to be processed, the first motor 36 can be started, and the first motor 36 can drive the threaded rod 35 to rotate. Since the threaded rod 35 and the threaded hole 34 are threadedly connected, the threaded rod 35 can be raised and lowered. When the threaded rod 35 moves, the top plate 37 can also slide on the surface of the sliding rod 38. At the same time, the threaded rod 35 can also drive the scraper 302 to scrape the inner wall of the barrel body 4, and the chemical raw material residues adhered to the inner wall of the barrel body 4 can be scraped off and collected, so that when the inner wall of the barrel body 4 is flushed in the later stage, no waste of chemical raw materials will be caused.
