A second discharge pipe 13 is obliquely provided at the bottom of the star-shaped discharger 14, and the lower end side of the second discharge pipe 13 is connected to the feeding chamber 1-2, and a spiral conveying blade 17 is rotatably provided in the feeding chamber 1-2. A third motor 16 is provided at the top of the shell 1, and the output end of the third motor 16 is connected to the spiral conveying blade 17. A third discharge pipe 15 is obliquely provided near the top of the second arc-shaped partition 3, and the lower end side of the third discharge pipe 15 is connected to the stirring chamber 1-1, and a discharge valve 18 is provided at the bottom of the feeding chamber 1-2; the stirring assembly includes a second motor 9, a second rotating shaft 10 and a plurality of stirring rods 11, the second motor 9 is provided at the top of the shell 1, the second rotating shaft 10 is connected to the output end of the second motor 9 and is rotatably provided in the stirring chamber 1-1, and the plurality of stirring rods 11 are provided on the second rotating shaft 10; a pair of through grooves 6-1 are opened on each of the rotating drums 6, and the pair of through grooves 6-1 are arranged opposite to each other.

[0017] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] In the present invention, the first motor 8, the second motor 9, the star-shaped discharger 14 and the third motor 16 are all connected to the external electric control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0019] According to the instruction manual Figure 1-3It can be seen that when the present invention is in use, the alloy powder raw materials to be mixed are transported into a pair of first hoppers 4, and the first motor 8 arranged on the first discharge pipe 5 is started. The output end of the first motor 8 drives the connected first rotating shaft 7 to rotate, and the first rotating shaft 7 drives the connected pair of rotating drums 6 to rotate in the pair of first discharge pipes 5. Since a plurality of through grooves 6-1 are provided on each rotating drum 6 and the through grooves 6-1 on the pair of rotating drums 6 are staggered, when the pair of rotating drums 6 rotate, the raw materials in the pair of first hoppers 4 can be alternately dropped into the shell 1, thereby preventing the same raw materials from accumulating inside the shell 1, and the raw materials in the stirring chamber 1-1 are stirred by the stirring assembly. After stirring for a period of time, the star-shaped discharger 14 is started to allow the preliminarily stirred raw materials to be transported through the second discharge pipe 13 arranged obliquely downward. The raw materials are sent to the feeding chamber 1-2, and the third motor 16 arranged at the top of the shell 1 is started. The third motor 16 drives the spiral conveying blade 17 to rotate, and then the raw materials at the bottom of the feeding chamber 1-2 are transported upward, and then transported to the stirring chamber 1-1 through the third discharge pipe 15, so that the raw materials are turned up and down to improve the mixing effect. When the mixing is completed, the discharge valve is opened to discharge the raw materials outward from the discharge valve; the utility model drives a pair of rotating drums 6 to rotate by the first motor 8, so that the raw materials in a pair of first hoppers 4 alternately fall into the stirring chamber 1-1, to prevent the same raw materials from accumulating in the shell 1 and resulting in low stirring efficiency. After the stirring assembly is initially mixed, the star-shaped discharger 14 and the third motor 16 are started to make the raw materials turn up and down in the shell 1 to further improve the mixing effect.

[0020] In one possible implementation, when the output end of the second motor 9 rotates, it drives the connected second rotating shaft 10 to rotate, and the second rotating shaft 10 drives multiple stirring rods 11 provided thereon to rotate, and the multiple stirring rods 11 mix and stir the raw materials.

[0021] There is a possible implementation in which a pair of through grooves 6-1 are relatively provided on each rotating drum 6, so that the raw materials in the first hopper 4 can fall into the through grooves 6-1 respectively, and enter the stirring chamber 1-1 when the through grooves 6-1 rotate downward.

[0022] 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.
