[0034] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figure 1 - Figure 2 This embodiment provides a feeding device with stirring, including: a hopper 1, the hopper 1 having an inlet 13 and an outlet 14, the outlet 14 being used to communicate with the production host 7; a rotating spiral stirring and feeding assembly 2 located in the hopper 1; a drive assembly 3, the drive shaft of the drive assembly 3 being connected to the spiral stirring and feeding assembly 2; and a lifting assembly 4, the fixed end of the lifting assembly 4 being used to connect to the production host 7, and the movable end of the lifting assembly 4 being connected to the hopper 1.

[0037] Specifically, the hopper 1 is used to hold raw materials, the inlet 13 is used to connect with the relevant loss-in-weight scale 8, so that the raw materials on the loss-in-weight scale 8 can enter the hopper 1 through the inlet 13, and the outlet 14 is used to connect with the relevant production host 7, so that the raw materials in the hopper 1 can enter the production host 7 through the outlet 14; the spiral mixing and feeding assembly 2 is not only used to perform secondary mixing and stirring of the raw materials to make the mixing uniformity of the raw materials, but also used to spirally convey the raw materials to reduce the conveying speed of the raw materials and prevent the raw materials from falling freely, thereby preventing the raw materials from having a large impact on the production host 7; the drive assembly 3 is used to drive the spiral mixing and feeding assembly 2 to rotate, and the drive assembly 3 may include a servo motor or a stepper motor, etc.; the lifting assembly 4 is used to realize the lifting and lowering of the hopper 1, the spiral mixing and feeding assembly 2 and the drive assembly 3, etc., so that the height of the hopper 1 can be adjusted according to the height of the relevant production host 7, and has good versatility to adapt to production host 7 of different heights. The lifting assembly 4 can be hydraulic, pneumatic or electric, etc., preferably hydraulic, so as to have a strong lifting force.

[0038] Furthermore, such as Figure 1 - Figure 2The hopper 1 includes: a conical section 11, with an inlet 13 located at the large-diameter end 111 of the conical section 11; a cylindrical section 12, with one end of the cylindrical section 12 connected to the small-diameter end 112 of the conical section 11, and an outlet 14 located at the other end of the cylindrical section 12; wherein, the spiral stirring and feeding assembly 2 is rotatably located inside the conical section 11 and the cylindrical section 12, and the movable end of the lifting assembly 4 is connected to the conical section 11.

[0040] Furthermore, such as Figure 1 It also includes a level gauge 5, the detection end of which is located inside the conical portion 11 near the large diameter end 111. Specifically, since the detection end of the level gauge 5 is located inside the conical portion 11 near the large diameter end 111, the level gauge 5 is equivalent to being used as a high-level level gauge to prevent the material level in the silo 1 from being too high. The level gauge 5 can be mechanical or capacitive, etc.

[0041] Furthermore, such as Figure 1 - Figure 2 It also includes a scraper rod 6 connected inside the conical portion 11 near the small diameter end 112.

The motor 31 can be a servo motor or a stepper motor, etc.; the gearbox 32 is used to change the speed and torque.

[0045] Furthermore, such as Figure 1 The lifting assembly 4 includes: a hydraulic cylinder 41, the cylinder body of which is connected to the production host 7, and the piston rod of the hydraulic cylinder 41 connected to the hopper 1; and a hydraulic oil supply unit communicating with the cylinder body of the hydraulic cylinder 41.
