[0025] Example

[0026] The following is further described in conjunction with specific embodiments. Figures 1 - 5 As shown, the utility model is a gypsum mixing device, comprising a stirring main rod 1 and stirring blades 2. The stirring main rod 1 is provided with a plurality of annular grooves 11 spaced apart in the axial direction. A pull rod 14 is coaxially rotatably sleeved on the top of the stirring main rod 1. The stirring main rod 1 can be moved by toggling the pull rod. The stirring blades 2 are installed in multiple groups and correspond to the plurality of annular grooves 11 one by one. Each group of stirring blades 2 includes two stirring blades 2. The cross section of each stirring blade 2 is semicircular. Each group of stirring blades 2 is hingedly mounted on the stirring main rod 1 by a hinge shaft 21 on the same side in the length direction and is surrounded in the annular groove 11. The axial direction of the hinge shaft 21 is perpendicular to the axial direction of the stirring main rod 1. When each group of stirring blades 2 rotates into the annular groove 11, the outer wall of the stirring blade 2 is flush with the outer wall of the stirring main rod 1.

[0027] Reference Figure 2 , Figure 3 The cleaning sleeve 3 is slidably mounted on the stirring main rod 1, and the cleaning sleeve 3 and the stirring main rod 1 are in an interference fit. When the cleaning sleeve 3 slides along the stirring main rod 1, it will play a role in cleaning the gypsum mixture. At the same time, when the stirring main rod 1 rotates, the cleaning sleeve 3 will not slide up and down freely. A plurality of cleaning sleeves 3 are installed, and each group of stirring blades 2 corresponds to each other one by one to improve the cleaning efficiency. A driving rod 32 is installed on the cleaning sleeve 3, and the driving rod 32 is welded on all the cleaning sleeves 3 at the same time. The top of the driving rod 32 is bent to facilitate the staff to hold it. The two end walls in the axial direction of the cleaning sleeve 3 are coaxially fixed with cleaning scraper rings 31. The cleaning scraper ring 31 is conically arranged. The cleaning scraper ring 31 is made of elastic material, and its inner diameter is smaller than the outer diameter of the stirring main rod 1. Under the joint action of the cleaning sleeve 3 and the cleaning scraper ring 31, the stirring blades 2 and the gypsum mixture on the stirring main rod 1 can be effectively cleaned and scraped.

[0028] Reference Figure 3 , Figure 4 The reset member 4 is installed at the hinge position of the stirring blade 2 and the stirring main rod 1, and is used to drive the stirring blade 2 and the stirring main rod 1 to be inclined. The reset member 4 is a spring 41, and the spring 41 is sleeved on the hinge shaft 21 between the stirring blade 2 and the stirring main rod 1. One end of the spring 41 is fixed on the stirring main rod 1, and the other end is fixed on the stirring blade 2. In other implementations, the reset member 4 can be a spring.

[0029] Reference Figure 1 , Figure 5In order to facilitate the stirring of gypsum mixture, the gypsum mixing device also includes a mixing barrel 5, the top of the mixing barrel 5 is open, and a mounting plate 6 is installed across the top of the mixing barrel 5. The bottom walls of both sides of the mounting plate 6 are provided with card slots 62, and the card slots 62 are arranged at the barrel mouth position of the top wall of the mixing barrel 5. The card slots 62 can facilitate the installation and removal of the mounting plate 6, and a serpentine through groove 61 is provided on the mounting plate 6. The serpentine through groove 61 extends along the length direction of the mounting plate 6. The stirring main rod 1 is penetrated by the serpentine through groove 61. A limiting ring 12 is coaxially fixed and welded on the stirring main rod 1. The limiting ring 12 is annular. The mounting plate 6 is located at the position of the serpentine through groove 61. A limiting groove 611 is provided along the direction of the serpentine through groove 61. The limiting groove 611 is located in the middle position of the mounting plate 6 in the thickness direction, and the limiting ring 12 is slidably connected in the limiting groove 611.

[0030] Reference Figure 1 , Figure 5 A rack 7 is fixedly welded on the mounting plate 6, and the rack 7 is located at the top of the mounting plate 6. The rack 7 is arranged along the length direction of the serpentine through groove 61 and is arranged parallel to the serpentine through groove 61. A gear 13 is coaxially fixed on the stirring main rod 1, and the gear 13 is meshed with the rack 7. When the stirring main rod 1 is moved along the path of the serpentine through groove 61, the stirring main rod 1 will rotate with the gear 13 to improve the stirring efficiency of the stirring blade 2.

[0031] The working process of this embodiment is as follows: the staff first aligns the slot 62 of the mounting plate 6 with the top wall barrel mouth position of the mixing barrel 5, installs the mounting plate 6, and then holds the lever and pushes the lever back and forth along the serpentine groove 61. Due to the mutual engagement of the rack 7 and the gear 13, the stirring main rod 1 and the stirring blade 2 will rotate along the serpentine groove 61, thereby achieving efficient stirring of the gypsum mixture. When the stirring is completed, the stirring main rod 1 and the mounting plate 6 are lifted, and the driving rod 32 is pushed back and forth up and down. Under the action of the cleaning sleeve 3 and the cleaning scraper ring 31, the stirring blade 2 will swing back into the annular groove 11, and quickly achieve the purpose of sliding and scraping off the gypsum mixture on the stirring blade 2 and the stirring main rod 1, effectively reducing the cleaning difficulty and reducing the time cost. The limiting groove 611 and the limiting ring 12 can limit the stirring main rod 1, so that it moves along the path of the serpentine groove 61, thereby further improving the stirring efficiency of the gypsum mixture.
