[0002] Dry-mixed mortar (also known as dry powder mortar or dry-mixed mortar) is a precast material produced through industrial production by mixing dried fine aggregates (such as quartz sand), cementitious materials (such as cement), mineral admixtures, and additives in a scientifically proportioned ratio. Its core feature is that it is pre-mixed in the factory and ready to use after adding water on site, avoiding the quality instability problems of traditional on-site mixing.

It includes a mixing tank and a cooling layer. The mixing tank is wrapped with the cooling layer, and a rotating shaft, which is a hollow cylinder, is provided inside the mixing tank. The rotating shaft is connected to the mixing tank via bearings, and both ends of the rotating shaft pass through the cooling layer. The portion of the rotating shaft located in the cooling layer has through holes, and coolant is filled into the cooling layer, entering the rotating shaft through the through holes for cooling. This application, by placing the cooling layer on the outer wall of the mixing tank and connecting the hollow rotating shaft to the cooling layer through through holes, ensures that the coolant cools the tank from the outside in within the cooling layer, and also allows the coolant to cool from the inside out within the rotating shaft.

When the first motor 25 is started, it drives the screw 24 to rotate, which in turn drives the lifting block 23 to move vertically, which in turn drives the moving plate 26 and the unblocking rod 27 to move vertically. The unblocking rod 27 can be moved into the feed pipe 11 to quickly unblock the raw material clogged in the feed pipe 11 without manual unblocking, greatly improving unblocking efficiency. A third motor 41 is fixedly connected to the top of the moving plate 26, along with the unblocking rod 27. A spiral conveyor blade 42 is fixedly connected to the outer side. The output end of a third motor 41 is fixedly connected to the top of a clearing rod 27. When the third motor 41 is started, it can drive the clearing rod 27 to rotate, which in turn drives the spiral conveyor blade 42 to rotate, thereby clearing the blocked material and further improving the clearing efficiency. A horizontal plate 51 is fixedly connected to one side of the mixing tank 1. A fourth motor 52 is fixedly connected to the bottom of the horizontal plate 51. A rotating shaft 53 is fixedly connected to the top of the fourth motor 52. A rotating seat 54 is fixedly connected to the top of the rotating shaft 53. The rotating seat 54 is fixedly connected to the vertical plate 21. The fourth motor 52 is rotatably connected to the horizontal plate 51. It can drive the rotating shaft 53 to rotate, which in turn drives the rotating seat 54 to rotate, which in turn drives the vertical plate 21 to rotate, which in turn drives the unblocking rod 27 to rotate to the other side, preventing it from being located above the feed pipe 11 and affecting normal feeding. The top of the horizontal plate 51 is provided with a rotating groove 61. Rotating blocks 62 are slidably connected to the four sides of the rotating groove 61. The rotating blocks 62 are fixedly connected to the rotating seat 54. The rotation of the rotating seat 54 can drive the rotating blocks 62 to rotate.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5The cleaning components include a second motor 31 fixedly connected to the top of the mixing tank 1, a stirring shaft 32 fixedly connected to the bottom of the second motor 31, two connecting plates 33 fixedly connected to both sides of the stirring shaft 32, a first scraper 34 fixedly connected to the connecting plates 33, and multiple first blades 35 fixedly connected to the stirring shaft 32. The stirring shaft 32 is rotatably connected to the mixing tank 1, and the first scraper 34 contacts the inner wall of the mixing tank 1. The second motor 31 can drive the stirring shaft 32 to rotate, which in turn can drive the first blades 35 to rotate, thus stirring the raw materials. At the same time, it can also drive the first scraper 34 to rotate, so that the first scraper 34 can scrape off the material remaining on the inner wall of the mixing tank 1, which can prevent the residue from affecting the interior of the mixing tank 1. In the space, support rods 71 ​​are fixedly connected to both sides of the lower part of the stirring shaft 32. A second scraper 72 is fixedly connected to one end of the support rod 71. The second scraper 72 is in contact with the inner wall of the mixing tank 1. The rotation of the stirring shaft 32 can drive the support rods 71 ​​to rotate, which in turn can drive the second scraper 72 to rotate. The second scraper 72 can clean the residual raw materials at the bottom of the mixing tank 1, which can further improve the cleaning efficiency. A rotating port 81 is opened on the first blade 35. A fixed shaft 82 is rotatably connected to the inner wall of the rotating port 81. A second blade 83 is fixedly connected to the outer side of the fixed shaft 82. When the first blade 35 rotates, the second blade 83 can drive the fixed shaft 82 to rotate due to the obstruction of the raw materials, which can indirectly improve the mixing efficiency of the raw materials.

[0026] Working principle: During operation, raw materials are fed into the mixing tank 1 through the feed pipe 11. The second motor 31 is started, which drives the stirring shaft 32 to rotate. The rotation of the stirring shaft 32 drives the first blade 35 to rotate, thereby mixing the raw materials. Due to the presence of the raw materials, the second blade 83 can rotate freely, further improving the mixing efficiency. When the feed pipe 11 becomes blocked, the fourth motor 52 is started. The fourth motor 52 drives the rotating shaft 53 to rotate, which in turn drives the rotating seat 54 to rotate, which in turn drives the vertical plate 21 to rotate, which in turn drives the moving plate 26 to rotate, causing the unblocking rod 27 to rotate above the feed pipe 11. The first motor 25 is then started. The screw 24 rotates, which in turn moves the lifting block 23 downward, thereby moving the moving plate 26 and the unblocking rod 27 downward. The third motor 41 starts, which drives the unblocking rod 27 to rotate, which in turn drives the spiral conveyor blade 42 to rotate. As the unblocking rod 27 descends, it pushes the blocked material into the mixing tank 1, quickly clearing the feed pipe 11. After clearing, the third motor 41 is turned off, the first motor 25 reverses, causing the unblocking rod 27 to move upward and reset. The fourth motor 52 reverses, which drives the unblocking rod 27 to rotate, moving it away from the feed pipe 11 to avoid affecting the feeding. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
