At the same time, according to the above, the speed of the first slave gear b6 is faster than that of the second slave gear b7, providing that the speed at which multiple groups of second augers f rotate around the first augers e is slower than the speed at which multiple groups of second augers f and the first augers e themselves rotate, so as to be more in line with practical use. Embodiment 2:

[0020] like Figures 1 to 5 As shown, the difference between it and the embodiment 1 is that it also includes a material discharge component 6, which is fixed outside the second linkage component d to follow the plurality of groups of second augers f to rotate around outside the first augers e; when the first augers e and the plurality of groups of second augers f extend into the barrel body 3, the material discharge component 6 can be annularly fed into the barrel body 3 to improve uniformity and reduce the possibility of block generation; The above-mentioned blanking assembly 6 is specifically implemented as follows: The material discharge assembly 6 comprises an annular material shell 61, a material cavity 62 in the annular material shell 61, an annular material inlet 63 provided on the annular material shell 61 to connect the material cavity 62 with the outside of the annular material shell 61, a concave cavity 64 on the annular material shell 61 for the second rotating rod c4 to penetrate, a plurality of groups of through holes 65 evenly provided at the bottom end of the annular material shell 61, and a stabilizing shell assembly 66 fixed on the annular material shell 61 and the second linkage assembly d, and the material cavity 62 gradually decreases from top to bottom; when the first auger e and a plurality of groups of second auger f extend into the barrel body 3, the plurality of groups of through holes 65 are all located on the inner side directly above the barrel body 3; like Figure 2 , 4 As shown in Figure 5, a stabilizing shell component 66 is fixedly installed on the periphery of the second linkage component d, and the stabilizing shell component 66 is connected to the annular material shell 61 for fixing, and the annular material shell 61 surrounds the stirring mechanism 4 in an annular manner. In order to provide the movement of the second rotating rod c4, a concave cavity 64 is also set on the inner side of the annular material shell 61, and an annular material inlet 63 is set on the upper side of the periphery of the annular material shell 61. In this way, when adding materials, the annular material shell 61 itself rotates, and only needs to be at a fixed position to evenly add another part of the mixed material that is prone to agglomeration to the annular material inlet 63, and the multiple groups of through holes 65 at the bottom of the annular material shell 61 are used to evenly disperse the materials into the barrel 3 and cooperate with the high-speed uniform function of the stirring mechanism 4 for rapid diffusion, so as to further reduce the generation of agglomerates. At the same time, the stabilizing shell component 66 can generate continuous vibration to the annular material shell 61 to ensure the smoothness of the through hole 65 when the materials are discharged: The structure of the above-mentioned housing stabilizing component 66 is specifically implemented as follows: The stabilizing shell assembly 66 comprises an extension plate 661 fixed to the ring plate d4, a plurality of groups of elastic members 662 uniformly fixed between the extension plate 661 and the outside of the annular shell 61, a plurality of groups of brackets 663 fixed to the outside of the support plate a, a plurality of groups of vibration motors 664 fixed to the brackets 663, rolling members 665 fixed to the outside of the vibration motors 664, a guide groove 666 for the rolling end of the rolling member 665 to be placed in a movable manner, and a convex ring 667 fixed to the outside of the annular shell 61, the guide groove 666 is provided on the convex ring 667, a wear-resistant pad is fixedly attached to the inner wall of the guide groove 666 and is attached to the rolling end of the rolling member 665, the convex ring 667 is located on the side of the annular shell 61 facing downward, the elastic member 662 can be a spring, the rolling member 665 can be a universal ball or roller, and the wear-resistant pad is a rubber pad; like Figure 2 , 4As shown in , 5, the extension plate 661 is annular and extends and is fixedly arranged on the periphery of the ring plate d4. A plurality of groups of elastic members 662 are elastically connected between the bottom end of the extension plate 661 and the annular shell 61 to provide stability for the annular shell 61; two groups of brackets 663 are symmetrically fixed on the left and right sides of the support plate a, a part of the bracket 663 is on the side of the annular shell 61 facing downward, and two groups of vibration motors 664 are installed on the bracket 663 on the side of the annular shell 61 facing downward, and a rolling member 665 is installed on the vibration motor 664 to further drag the annular shell 61 by fitting on the rubber pad of the guide groove 666, so that the stability of the annular shell 61 after installation is better; At the same time, the elastic member 662 provides elastic compression for the annular material shell 61, so that the rolling member 665 fits more stably on the rubber pad. When the annular material shell 61 rotates, the rolling member 665 has good stability when it rolls in close contact. When the vibration motor 664 generates vibration, the elastic member 662 can also reduce the hard transmission to the extension plate 661, so as to provide good protection for the stirring mechanism 4. At the same time, the vibration motor 664 is selected to have a smaller amplitude. When the vibration motor 664 generates vibration, it can ensure that the rolling member 665 will not fall out of the guide groove 666.

[0021] A mixing process for a compound thickener is proposed, which comprises the following steps: S1: stably placing the barrel 3 on the frame 1, placing part of the mixed material that will not or is not likely to form lumps into the barrel 3 in advance, and connecting the controller 5 to an external power supply; S2: The controller 5 is operated to start the lifting mechanism 2 to drive the stirring mechanism 4 to move downward until the first auger e and several groups of second auger f extend into the barrel 3; S3: The controller 5 is operated to start the stirring mechanism 4, and the first auger e rotates to make part of the mixed material put into the barrel 3 surge upward, while the second auger f of several groups rotates in the opposite direction to make the mixed material outside the upwardly surging mixed material surge downward, thereby forming a mixing mode of up and down circulation flow to improve efficiency. At the same time, the second auger f of several groups can also rotate synchronously around the first auger e, thereby strengthening the stirring surface of the mixed material and further improving the mixing efficiency. S4: According to the above, when part of the mixed material is stirred evenly, another part of the mixed material that is prone to agglomeration is discharged into the barrel 3 at the discharge assembly 6, and the discharge follows a plurality of groups of second auger f rotating around the outside of the first auger e to enter, which can improve the uniformity of the discharge position, and cooperate with the high-speed uniform function of the stirring mechanism 4 for rapid diffusion, so as to further reduce the generation of agglomerates; S5: After the mixing is completed, the controller 5 turns off the operation of the stirring mechanism 4 and controls the stirring mechanism 4 to move upward, and the barrel 3 can be directly lifted out. Only the first auger e and several groups of second auger f are in contact with the mixture and are directly exposed, so they can be easily cleaned.

[0022] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.
