DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-3 As shown, the food raw material mixing device comprises a container 1, the inner cavity of the container 1 is a conical shape with a larger upper portion and a smaller lower portion, a container lid 11 is sealed on the top of the container 1, a discharge port 13 is provided at the bottom of the container 1, and a valve is provided at the discharge port 13. A shaft 3 is provided inside the container 1 along the axis, and the top of the shaft 3 slides vertically through the container lid 11;

[0022] like Figure 2-4As shown, the driving device includes a motor 2, which is mounted on the surface of the tank cover 11. The output shaft of the motor 2 is fixed with a driving gear 21. A driven gear 22 is rotatably mounted on the surface of the tank cover 11. The shaft 3 slides through the driven gear 22. A sliding key 24 is fixed on the inner side of the driven gear 22. A key groove 23 is axially provided on the surface of the shaft 3. The sliding key 24 slides axially with the key groove 23, and the driving gear 21 is meshed with the driven gear 22.

[0023] like Figure 1-3 As shown, the lifting assembly includes an electric telescopic rod 4, which is installed on the surface of the tank cover 11. The telescopic end of the electric telescopic rod 4 is upwardly connected to a connecting frame 41, and the connecting frame 41 is rotatably connected to the top end of the shaft 3;

[0024] like Figure 2-3 As shown, the shaft 3 is fixedly connected to the spiral plate 5 through evenly distributed support rods 51. The spiral diameter of the spiral plate 5 gradually decreases from top to bottom, so that the outer edge of the spiral plate 5 is adapted to the inner wall of the container 1.

[0025] The material is fed into the container 1 at a fixed ratio through the feeding port 12. When the stirring operation is started, the electric telescopic rod 4 is kept extended, so that the shaft 3 drives the spiral plate 5 to rise and there is a gap between it and the inner wall of the container 1. The motor 2 is turned on to drive the driving gear 21 and the driven gear 22 to rotate. The shaft 3 drives the spiral plate 5 to rotate through the torsion limit of the sliding key 24 and the keyway 23. The rotating spiral plate 5 mixes and stirs the material;

[0026] When discharging, the discharge port 13 is opened, and the electric telescopic rod 4 is turned on and retracted, so that the shaft 3 drives the spiral plate 5 to descend, and the outer edge of the spiral plate 5 is in contact with the inner wall of the storage tank 1. The motor 2 is turned on to drive the spiral plate 5 to rotate, and the spiral plate 5 has a tendency to rotate downward to push the material, thereby promoting the material to be discharged from the discharge port 13. At the same time, the spiral plate 5 contacts the inner wall of the storage tank 1 to scrape the material downward, reducing the material adhering to the inner wall of the storage tank 1.

[0027] like Figure 2-3 As shown, an inclined stirring plate 6 is fixed on the surface of the support rod 51. The setting of the stirring plate 6 increases the amplitude of stirring the material. The direction of rotation and pushing of the stirring plate 6 is opposite to the direction of rotation and pushing of the spiral plate 5, so that the material can be circulated and stirred, thereby improving the mixing efficiency.

[0028] A vertically extending shaft sleeve 14 is fixed to the surface of the tank cover 11, and the shaft rod 3 slides through the shaft sleeve 14 to improve the stability of the vertical sliding of the shaft rod 3. A spring is connected between the connecting frame 41 and the tank cover 11, so that the connecting frame 41 and the shaft rod 3 have a tendency to move upward elastically. The setting of the spring is used to share the counterweight carried by the electric telescopic rod 4, so as to keep the spiral plate 5 stable in a mixed working state.

[0029] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
