[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 An embodiment of the utility model provides a stirring and mixing device for mixing mortar admixtures, comprising: a stirring tank 1 and a forward and reverse motor 2.

[0019] Among them, Figure 1As shown, the forward and reverse motor 2 is installed on the top of the mixing tank 1, and the rotating shaft tube of the forward and reverse motor 2 passes through the top of the mixing tank 1 and is fixedly connected to a rotating rod 3. A stirring blade 4 is installed on the outer wall of the rotating rod 3. One end of the bottom of the rotating rod 3 is rotatably installed on the bottom inner wall of the mixing tank 1 through a bearing. The forward and reverse motor 2 drives the rotating rod 3 and the stirring blade 4 on its outer wall clockwise to start rotating, and the mortar admixture in the mixing tank 1 is stirred. One end of the bottom of the rotating rod 3 is installed on the bottom inner wall of the mixing tank 1 through a bearing, so that the rotating rod 3 remains stable during rotation.

[0020] Furthermore, a shield 10 is installed on the top of the mixing tank 1 , and the forward and reverse motor 2 is located inside the shield 10 . The shield 10 can cover and protect the forward and reverse motor 2 .

[0021] In this embodiment, Figure 1-Figure 3 As shown, an inner ratchet 13 is installed on the inner wall of the bottom of the mixing tank 1 through a turntable 15, and no less than three L-shaped scrapers 7 are symmetrically installed on the outer wall of the inner ratchet 13. A sleeve 12 is fixedly connected to the outer wall of the rotating rod 3, and a pawl 14 is elastically connected to the sleeve 12. The pawl 14 is located inside the inner ratchet 13.

[0022] When the forward and reverse motor 2 drives the rotating rod 3 to rotate counterclockwise, the sleeve 12 and the pawl 14 are driven to rotate counterclockwise, and the pawl 14 drives the inner ratchet 13 to rotate, so that the L-shaped scraper 7 rotates with the inner ratchet 13 to scrape the mortar admixture attached to the inner wall of the mixing tank 1.

[0023] Furthermore, a support plate 8 is fixedly connected to the top of the L-shaped scraper 7 , and the support plate 8 can improve the stability of the top of the L-shaped scraper 7 .

[0024] like Figure 1 As shown, the top of the mixing tank 1 is connected to a feed pipe 5, the bottom of the mixing tank 1 is connected to a discharge pipe 6, and the top of the mixing tank 1 is connected to a feeding pipe 9. Concrete mortar can enter the mixing tank 1 through the feed pipe 5, and the mortar admixture can be added into the mixing tank 1 through the feeding pipe 9. After the concrete mortar is mixed with the mortar admixture, it can be discharged to the outside through the discharge pipe 6.

[0025] Specifically, a support column 11 is installed at the bottom of the mixing tank 1 , and the support column 11 can support and stabilize the mixing tank 1 .

[0026] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the utility model is used, the forward and reverse motor 2 drives the rotating rod 3 and the stirring blades 4 on its outer wall clockwise to start rotating, and the mortar admixture in the mixing tank 1 is stirred. One end of the bottom of the rotating rod 3 is installed on the bottom inner wall of the mixing tank 1 through a bearing, so that the rotating rod 3 remains stable during rotation.

[0027] In addition, the outer wall of the rotating rod 3 is fixedly connected to a sleeve 12, and a pawl 14 is elastically connected to the sleeve 12. The pawl 14 meshes with the inside of the inner ratchet 13. When the forward and reverse motor 2 drives the rotating rod 3 to rotate counterclockwise, the sleeve 12 and the pawl 14 are driven to rotate counterclockwise. The pawl 14 pushes the inner ratchet 13 to rotate, so that the L-shaped scraper 7 rotates with the inner ratchet 13, scraping the mortar admixture attached to the inner wall of the mixing tank 1 to avoid deposition and attachment in the mixing tank 1, and quickly and effectively cleaning the inner wall of the mixing tank 1.
